More information about these and other discounts is available from your financial representative and on pages 29 to 31 of this prospectus under "Sales charge reductions and waivers" or pages 273 to 277 of the fund's Statement of Additional Information under "Sales Charges on Class A, Class B, and Class C Shares."&lt;/div&gt;

The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 18% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund seeks to achieve its objective by investing in alternative asset classes. The fund invests in other funds as well as other types of investments as described below.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund allocates its assets among other affiliated and unaffiliated underlying funds, including exchange-traded funds (ETFs), that emphasize alternative or nontraditional asset categories or investment strategies such as international small-cap stocks, emerging-market equity, commodities, market neutral (long/short), global real estate, natural resources, TIPS (Treasury Inflation-Protected Securities), global bonds, high yield, bank loans, foreign currency trading strategies, absolute return strategies, managed futures, arbitrage strategies, tactical investment strategies, and emerging-market debt. Some loans may be illiquid. The fund may purchase any underlying funds except other funds of funds. The fund may also invest directly in exchange-traded notes (ETNs). The fund may use a portion of its assets to employ a market neutral (long/short) strategy by simultaneously purchasing a security and entering into a short sale on the security.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may use various investment strategies such as hedging and other related transactions, including derivative instruments such as options, futures, and swaps. Derivatives may be used for hedging purposes, including hedging various market risks and managing the effective maturity or duration of debt instruments held by the fund. These strategies also may be used to gain exposure to a particular security or securities market. The fund also may purchase and sell commodities and may enter into swap contracts and other commodity-linked derivative instruments, including those linked to physical commodities.&lt;/div&gt;

Many factors affect performance, and fund shares will fluctuate in price, meaning you could lose money. The fund's investment strategy may not produce the intended results.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;During periods of heightened market volatility or reduced liquidity, governments, their agencies, or other regulatory bodies, both within the United States and abroad, may take steps to intervene. These actions, which could include legislative, regulatory, or economic initiatives, might have unforeseeable consequences and could adversely affect the fund's performance or otherwise constrain the fund's ability to achieve its investment objective.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund's main risks are listed below in alphabetical order. &lt;i&gt;Before investing, be sure to read the additional descriptions of these risks beginning on page 8 of the prospectus.&lt;/i&gt;

               &lt;b&gt;Asset allocation risk.&lt;/b&gt; Although allocation among asset categories generally limits exposure to any one category, the management team may favor a category that performs poorly relative to others. Alternative asset categories may underperform the general stock market.&lt;/div&gt;

               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;

               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;

               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;

               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;

               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;

               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;

               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: foreign currency forward contracts, futures contracts, swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;

               &lt;b&gt;Short sales risk.&lt;/b&gt; In a short sale, a fund pays interest on the borrowed security. The fund will lose money if the security price increases between the short sale and the replacement date.&lt;/div&gt;

               &lt;b&gt;Absolute return risk.&lt;/b&gt; Although a manager may aim to maximize absolute return, there is no guarantee that a fund will generate positive returns.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Arbitrage securities and distressed companies risk.&lt;/b&gt; A merger or other restructuring, tender offer, or exchange offer proposed or pending at the time of investment in risk arbitrage securities may not be completed on the terms contemplated, resulting in losses.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Currency risk.&lt;/b&gt; Fluctuations in exchange rates may adversely affect the U.S. dollar value of a fund's investments. Foreign currencies may decline in value, which could negatively impact performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Emerging-market risk.&lt;/b&gt; The risks of investing in foreign securities are magnified in emerging markets. Emerging-market countries may experience higher inflation, interest rates, and unemployment and greater social, economic, and political uncertainties than more developed countries.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;High portfolio turnover risk.&lt;/b&gt; Trading securities actively and frequently can increase transaction costs (thus lowering performance) and taxable distributions.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Loan participations risk.&lt;/b&gt; Participations and assignments involve special types of risks, including credit risk, interest-rate risk, counterparty risk, liquidity risk, risks associated with extended settlement, and the risks of being a lender.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Natural resources industry risk.&lt;/b&gt; The natural resources industry can be significantly affected by international political and economic developments, energy conservation and exploration efforts, commodity prices, and taxes and other governmental regulations, among other factors.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Real estate securities risk.&lt;/b&gt; Securities of companies in the real estate industry carry risks associated with owning real estate, including the potential for a decline in value due to economic or market conditions.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

               The following information illustrates the variability of the fund's returns and provides some indication of the risks of investing in the fund by showing changes in the fund's performance from year to year and by showing how the fund's average annual returns compared with a broad-based market index. Past performance (before and after taxes) does not indicate future results. All figures assume dividend reinvestment. Performance information is updated daily, monthly, and quarterly and may be obtained at our website, jhinvestments.com, or by calling 800-225-5291 (Class A and Class C shares), Monday to Thursday, 8:00 A.M.&#8212;7:00 P.M., and Friday, 8:00 A.M.&#8212;6:00 P.M., Eastern time, or 888-972-8696 (Class I, Class R2, Class R4, and Class R6 shares) between 8:30 A.M. and 5:00 P.M., Eastern time, on most business days.

Returns shown prior to a class's commencement date are those of Class A shares, except that they do not include sales charges and would be lower if they did. Returns for Class C, Class I, Class R2, Class R4, and Class R6 shares would have been substantially similar to returns of Class A shares because each share class is invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.&lt;/div&gt;

The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's performance. During its most recent fiscal year, the fund's portfolio turnover rate was 70% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund seeks to generate capital appreciation and income by investing at least 80% of net assets (plus borrowings for investment purposes) in a diversified portfolio of bonds issued by governments, government agencies, international organizations issuing supranational bonds, and corporate issuers in Asia.  Asia means those countries that are located on the Asian continent or are in the Asian region, including Australia and New Zealand. An issuer is considered to be in Asia if its principal place of business is in Asia or it is incorporated or domiciled in Asia or, for supranational issuers, its securities are denominated in Asian currencies.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in fixed-income securities of other issuers outside Asia if the manager considers that such securities may help to achieve the fund's investment objective. The fund may invest in cash and other liquid short-term fixed-income securities when the manager believes that the fund could benefit from maintaining a higher cash exposure, including for temporary defensive purposes.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in investment-grade fixed-income securities and below-investment-grade fixed-income securities (junk bonds). The fund may invest in securities of any maturity, and there is no limit on the maturities of the fixed-income securities in which the fund may invest. There is no limit on the types of issuers in which the fund may invest, which may include issuers of U.S. dollar-denominated securities of foreign governments and corporations, mortgage-related securities, municipal obligations, asset-backed securities, mortgage-backed securities, pay-in-kind bonds, high-yield bonds, emerging-market debt, distressed investments, loan participations, and U.S. TIPS (Treasury Inflation-Protected Securities). The fund may invest in securities with debt/equity characteristics such as preferred shares, convertible bonds, and warrants. The fund may also use derivatives for hedging and efficient portfolio management purposes by utilizing futures, options, options on futures, foreign currency forward contracts, and nondeliverable forwards.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is a non-diversified fund, which means that it may invest in a smaller number of issuers than a diversified fund and may invest more of its assets in the securities of a single issuer.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Many factors affect performance, and fund shares will fluctuate in price, meaning you could lose money. The fund's investment strategy may not produce the intended results.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;During periods of heightened market volatility or reduced liquidity, governments, their agencies, or other regulatory bodies, both within the United States and abroad, may take steps to intervene. These actions, which could include legislative, regulatory, or economic initiatives, might have unforeseeable consequences and could adversely affect the fund's performance or otherwise constrain the fund's ability to achieve its investment objective.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund's main risks are listed below in alphabetical order. &lt;i&gt;Before investing, be sure to read the additional descriptions of these risks beginning on page 5 of the prospectus.&lt;/i&gt;            
            &lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Asian risk.&lt;/b&gt; Some Asian securities tend to be volatile and may decline in value significantly. Certain companies in Asia may be more vulnerable to political or economic developments or lack access to efficient trading markets. Some Asian countries have restrictions on the extent to which foreigners may invest in their securities markets.&lt;/div&gt;

               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Distressed investments risk.&lt;/b&gt; Distressed investments, including loans, mortgages, bonds, and notes, may not be publicly traded and may involve substantial risk. A fund may lose up to its entire investment.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;

               &lt;b&gt;Greater China risk.&lt;/b&gt; Investments in the Greater China region may be subject to less developed trading markets, acute political risks such as possible negative repercussions resulting from China's relationship with Taiwan or Hong Kong, and restrictions on monetary repatriation or other adverse government actions. For example, a government may restrict investment in companies or industries considered important to national interests, or intervene in the financial markets, such as by imposing trading restrictions, or banning or curtailing short selling. A small number of companies and industries represent a relatively large portion of the Greater China market.&lt;/div&gt;

               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: foreign currency forward contracts, futures contracts, options on futures, and options. Foreign currency forward contracts, futures contracts, and options generally are subject to counterparty risk. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;

               &lt;b&gt;Loan participations risk.&lt;/b&gt; Participations and assignments involve special types of risks, including credit risk, interest-rate risk, counterparty risk, liquidity risk, risks associated with extended settlement, and the risks of being a lender.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Municipal bond risk.&lt;/b&gt; The prices of municipal bonds, including general obligation bonds, can decline if the issuer's credit quality declines. Revenue bond prices can decline if related projects become unprofitable. An insured municipal bond is subject to the risk that the insurer may be unable to pay claims and is not insured with respect to the market value of the obligation. Municipal bond income could become taxable in the future. Investments in AMT bonds may result in tax liability for shareholders.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Warrants risk.&lt;/b&gt; The prices of warrants may not precisely reflect the prices of their underlying securities. Warrant holders do not receive dividends or have voting or credit rights. A warrant ceases to have value if not exercised prior to its expiration date.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The following information illustrates the variability of the fund's returns and provides some indication of the risks of investing in the fund by showing changes in the fund's performance from year to year and by showing how the fund's average annual returns compared with a broad-based market index. Past performance (before and after taxes) does not indicate future results. The fund's custom blended benchmark comprises 50% J.P. Morgan Asia Credit Index/50% J.P. Morgan Emerging Local Market Plus Asia Index and shows how the fund's performance compares against the returns of similar investments. All figures assume dividend reinvestment. Performance information is updated daily, monthly, and quarterly and may be obtained at our website, jhinvestments.com, or by calling 800-225-5291 (Class A), Monday to Thursday, 8:00 A.M.&#8212;7:00 P.M., and Friday, 8:00 A.M.&#8212;6:00 P.M., Eastern time, or 888-972-8696 (Class I) between 8:30 A.M. and 5:00 P.M., Eastern time, on most business days.&lt;/div&gt;

Because Class A and Class I shares of the fund had not commenced operations as of the date of this prospectus, the returns shown are those of Class NAV shares, except that they include any sales charges. Returns for Class A and Class I shares would have been substantially similar to returns of Class NAV shares because each share class is invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Please note that after-tax returns (shown for Class A shares only) reflect the highest individual federal marginal income-tax rate in effect as of the date provided and do not reflect any state or local taxes. Your actual after-tax returns may be different. After-tax returns are not relevant to shares held in an IRA, 401(k), or other tax-advantaged investment plan. After-tax returns for other share classes would vary. The returns for Class A shares have been adjusted to reflect the reduction in the maximum sales charge from 4.50% to 4.00%, effective February 3, 2014.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's performance. During its most recent fiscal year, the fund's portfolio turnover rate was 25% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in the common stocks of large- and medium-sized blue chip growth companies. The manager defines blue chip growth companies as those well established in their industries and with the potential for above-average earnings growth.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;In identifying blue chip companies in which to invest, the manager generally considers whether they have viable or growing leading market positions, seasoned management teams, and strong financial fundamentals. This investment approach reflects the manager's belief that the combination of solid company fundamentals (with emphasis on the potential for above-average growth in earnings or operating cash flow) and a positive industry outlook will ultimately reward investors. The manager also seeks to invest in some companies with good prospects for dividend growth.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;While most of the assets of the fund are invested in U.S. common stocks, the fund may also invest in other types of securities, including (i) U.S. dollar- and foreign currency-denominated foreign securities (up to 20% of net assets), (ii) convertible stocks, warrants, and bonds, and (iii) futures and options. Combined investments in convertible securities, preferred stocks, and debt securities are limited to 25% of total assets. The fund may invest in debt securities of any type without regard to quality or rating, including those rated below investment-grade (junk bonds) (up to 5% of total assets). The fund's investment policies are based on credit ratings at the time of purchase. The fund's debt securities may include privately negotiated notes or loans, including loan participations and assignments (bank loans). Some loans may be illiquid.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund holds a certain portion of its assets in money market reserves consisting of shares of the T. Rowe Price Government Reserve Fund (or any other internal T. Rowe Price money market fund) or U.S. dollar- and foreign currency-denominated money market securities. These include repurchase agreements in the two highest rating categories that mature in one year or less. The fund may invest reserves in U.S. dollars and foreign currencies.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest up to 10% of its total assets in hybrid instruments. Hybrid instruments are a type of high-risk derivative which can combine the characteristics of securities, futures, and options. Such securities may bear interest or pay dividends at below market rates or even relatively nominal market rates.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;In pursuing the fund's investment objective, the manager may deviate from the fund's normal investment criteria to purchase securities the manager believes might appreciate substantially. The fund may invest significantly in the information technology sector, and the fund may at times invest significantly in stocks of technology companies.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Many factors affect performance, and fund shares will fluctuate in price, meaning you could lose money. The fund's investment strategy may not produce the intended results.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;During periods of heightened market volatility or reduced liquidity, governments, their agencies, or other regulatory bodies, both within the United States and abroad, may take steps to intervene. These actions, which could include legislative, regulatory, or economic initiatives, might have unforeseeable consequences and could adversely affect the fund's performance or otherwise constrain the fund's ability to achieve its investment objective.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund's main risks are listed below in alphabetical order. &lt;i&gt;Before investing, be sure to read the additional descriptions of these risks beginning on page 6 of the prospectus.&lt;/i&gt;            
            &lt;/div&gt;

               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Currency risk.&lt;/b&gt; Fluctuations in exchange rates may adversely affect the U.S. dollar value of a fund's investments. Foreign currencies may decline in value, which could negatively impact performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: futures contracts and options. Futures contracts and options generally are subject to counterparty risk.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hybrid instrument risk.&lt;/b&gt; Hybrid instruments entail greater market risk and may be more volatile than traditional debt instruments, may bear interest or pay preferred dividends at below-market rates, and may be illiquid. The risks of investing in hybrid instruments are a combination of the risks of investing in securities, options, futures, and currencies.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Information technology risk.&lt;/b&gt; Information technology companies can be significantly affected by rapid obsolescence, short product cycles, competition, and government regulation, among other factors. Investments in the technology sector may be susceptible to heightened risk of cybersecurity breaches, which may allow an unauthorized party to gain access to personally identifiable information and other customer data.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Investment company securities risk.&lt;/b&gt; A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;

               &lt;b&gt;Loan participations risk.&lt;/b&gt; Participations and assignments involve special types of risks, including credit risk, interest-rate risk, counterparty risk, liquidity risk, risks associated with extended settlement, and the risks of being a lender.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mid-sized company risk&lt;/b&gt;. Mid-sized companies are generally less established and may be more volatile than larger companies. Mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;

               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;

               &lt;b&gt;Technology companies risk.&lt;/b&gt; Technology companies can be significantly affected by rapid obsolescence, short product cycles, competition, and government regulation, among other factors. Investments in the technology sector may be susceptible to heightened risk of cybersecurity breaches, which may allow an unauthorized party to gain access to personally identifiable information and other customer data.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Telecommunications sector risk.&lt;/b&gt; Telecommunication services companies are subject to government regulation of services and rates of return and can be significantly affected by intense competition, among other factors.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Warrants risk.&lt;/b&gt; The prices of warrants may not precisely reflect the prices of their underlying securities. Warrant holders do not receive dividends or have voting or credit rights. A warrant ceases to have value if not exercised prior to its expiration date.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The following information illustrates the variability of the fund's returns and provides some indication of the risks of investing in the fund by showing changes in the fund's performance from year to year and by showing how the fund's average annual returns compared with a broad-based market index. Past performance (before and after taxes) does not indicate future results. The Russell 1000 Growth Index shows how the fund's performance compares against the returns of similar investments. All figures assume dividend reinvestment. Performance information is updated daily, monthly, and quarterly and may be obtained at our website, jhinvestments.com, or by calling 800-225-5291, Monday to Thursday, 8:00 A.M.&#8212;7:00 P.M., and Friday, 8:00 A.M.&#8212;6:00 P.M., Eastern time.&lt;/div&gt;

Class A and Class C shares commenced operations on March 27, 2015. Returns for Class A and Class C shares prior to their commencement date are those of Class NAV shares, except that they include any sales charges. Returns for Class A and Class C shares would have been substantially similar to returns of Class NAV shares because each share class is invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Please note that after-tax returns (shown for Class A shares only) reflect the highest individual federal marginal income-tax rate in effect as of the date provided and do not reflect any state or local taxes. Your actual after-tax returns may be different. After-tax returns are not relevant to shares held in an IRA, 401(k), or other tax-advantaged investment plan. After-tax returns for other share classes would vary.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's performance. During its most recent fiscal year, the fund's portfolio turnover rate was 25% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in the common stocks of large- and medium-sized blue chip growth companies. The manager defines blue chip growth companies as those well established in their industries and with the potential for above-average earnings growth.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;In identifying blue chip companies in which to invest, the manager generally considers whether they have viable or growing leading market positions, seasoned management teams, and strong financial fundamentals. This investment approach reflects the manager's belief that the combination of solid company fundamentals (with emphasis on the potential for above-average growth in earnings or operating cash flow) and a positive industry outlook will ultimately reward investors. The manager also seeks to invest in some companies with good prospects for dividend growth.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;While most of the assets of the fund are invested in U.S. common stocks, the fund may also invest in other types of securities, including (i) U.S. dollar- and foreign currency-denominated foreign securities (up to 20% of net assets), (ii) convertible stocks, warrants, and bonds, and (iii) futures and options. Combined investments in convertible securities, preferred stocks, and debt securities are limited to 25% of total assets. The fund may invest in debt securities of any type without regard to quality or rating, including those rated below investment-grade (junk bonds) (up to 5% of total assets). The fund's investment policies are based on credit ratings at the time of purchase. The fund's debt securities may include privately negotiated notes or loans, including loan participations and assignments (bank loans). Some loans may be illiquid.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund holds a certain portion of its assets in money market reserves consisting of shares of the T. Rowe Price Government Reserve Fund (or any other internal T. Rowe Price money market fund) or U.S. dollar- and foreign currency-denominated money market securities. These include repurchase agreements in the two highest rating categories that mature in one year or less. The fund may invest reserves in U.S. dollars and foreign currencies.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest up to 10% of its total assets in hybrid instruments. Hybrid instruments are a type of high-risk derivative which can combine the characteristics of securities, futures, and options. Such securities may bear interest or pay dividends at below market rates or even relatively nominal market rates.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;In pursuing the fund's investment objective, the manager may deviate from the fund's normal investment criteria to purchase securities the manager believes might appreciate substantially. The fund may invest significantly in the information technology sector, and the fund may at times invest significantly in stocks of technology companies.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Many factors affect performance, and fund shares will fluctuate in price, meaning you could lose money. The fund's investment strategy may not produce the intended results.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;During periods of heightened market volatility or reduced liquidity, governments, their agencies, or other regulatory bodies, both within the United States and abroad, may take steps to intervene. These actions, which could include legislative, regulatory, or economic initiatives, might have unforeseeable consequences and could adversely affect the fund's performance or otherwise constrain the fund's ability to achieve its investment objective.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund's main risks are listed below in alphabetical order. &lt;i&gt;Before investing, be sure to read the additional descriptions of these risks beginning on page 5 of the prospectus.&lt;/i&gt;            
            &lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Currency risk.&lt;/b&gt; Fluctuations in exchange rates may adversely affect the U.S. dollar value of a fund's investments. Foreign currencies may decline in value, which could negatively impact performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: futures contracts and options. Futures contracts and options generally are subject to counterparty risk.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hybrid instrument risk.&lt;/b&gt; Hybrid instruments entail greater market risk and may be more volatile than traditional debt instruments, may bear interest or pay preferred dividends at below-market rates, and may be illiquid. The risks of investing in hybrid instruments are a combination of the risks of investing in securities, options, futures, and currencies.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Information technology risk.&lt;/b&gt; Information technology companies can be significantly affected by rapid obsolescence, short product cycles, competition, and government regulation, among other factors. Investments in the technology sector may be susceptible to heightened risk of cybersecurity breaches, which may allow an unauthorized party to gain access to personally identifiable information and other customer data.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Investment company securities risk.&lt;/b&gt; A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Loan participations risk.&lt;/b&gt; Participations and assignments involve special types of risks, including credit risk, interest-rate risk, counterparty risk, liquidity risk, risks associated with extended settlement, and the risks of being a lender.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;

               &lt;b&gt;Mid-sized company risk&lt;/b&gt;. Mid-sized companies are generally less established and may be more volatile than larger companies. Mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;

               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;

               &lt;b&gt;Technology companies risk.&lt;/b&gt; Technology companies can be significantly affected by rapid obsolescence, short product cycles, competition, and government regulation, among other factors. Investments in the technology sector may be susceptible to heightened risk of cybersecurity breaches, which may allow an unauthorized party to gain access to personally identifiable information and other customer data.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The following information illustrates the variability of the fund's returns and provides some indication of the risks of investing in the fund by showing changes in the fund's performance from year to year and by showing how the fund's average annual returns compared with a broad-based market index. Past performance (before and after taxes) does not indicate future results. The Russell 1000 Growth Index shows how the fund's performance compares against the returns of similar investments. All figures assume dividend reinvestment. Performance information is updated daily, monthly, and quarterly and may be obtained at our website, jhinvestments.com, or by calling 888-972-8696 between 8:30 A.M. and 5:00 P.M., Eastern time, on most business days.&lt;/div&gt;

Because Class I shares of the fund had not commenced operations as of the date of this prospectus, the returns shown are those of Class NAV shares. Returns for Class I shares would have been substantially similar to returns of Class NAV shares because both share classes are invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.&lt;/div&gt;

Your actual after-tax returns may be different. After-tax returns are not relevant to shares held in an IRA, 401(k), or other tax-advantaged investment plan.&lt;/div&gt;

Please see below a hypothetical example showing the expenses of a $10,000 investment for the time periods indicated and then, except as shown below, assuming you sell all of your shares at the end of those periods. The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's performance. During its most recent fiscal year, the fund's portfolio turnover rate was 73% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund seeks to achieve its investment objective, under normal circumstances, by primarily investing in U.S. equities and simultaneously selling a call option against those stocks. The call options will typically have a strike price lower than the current stock price, which is termed "in the money." This combination of long stock position and short in the money call option creates a yield instrument. Additionally, the fund can engage in writing out-of-the-money put options on U.S. equities. Writing out-of-the-money put options is analogous to buying the stock and selling the call option with the same strike price and generally achieves the same result. These two strategies are equivalent in terms of risk/reward due to put-call parity. In making investment decisions, the manager ordinarily analyzes estimates of "intrinsic value" (i.e., the potential downside volatility level) and correlation between such estimates and time to expiration, as well as potential returns relative to risk.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The strike price of the call options is usually set at or below the estimated intrinsic value level of the securities against which they are sold and the time to expiration of the options that the fund sells varies. The fund may also write (sell) in-the-money call options on equity indexes and/or exchange-traded funds and write call options on individual securities that it does not hold in its portfolio (i.e., naked call options).&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The issuers of equity securities purchased by the fund will primarily have market capitalizations in excess of $2 billion. The fund may invest in companies located both within and outside the United States (including in emerging markets). The fund may invest any percentage of assets in any one country, region or geographic area. The fund may invest in initial public offerings (IPOs) and in exchange-traded funds (ETFs). In addition to common stocks and other equity securities (such as preferred stocks, convertible securities, and warrants), the fund may use foreign currency forward contracts, options, stock index futures contracts, and other derivative instruments, primarily for the purpose of reducing the risks of individual equity positions and maximizing risk-adjusted returns, and may also be used to hedge broad market exposure. In addition to the use of written option contracts, the fund may use foreign currency forward contracts, other options, stock index futures contracts, other futures and forward contracts, swap agreements, variance swaps, convertibles and reverse convertibles, and other derivative instruments for hedging purposes or to enhance return. Variance swap agreements involve an agreement by the two parties to exchange cash flows based on the measured variance (or square of volatility) of a specified underlying asset.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund's investment process may result in an extremely high portfolio turnover ratio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Many factors affect performance, and fund shares will fluctuate in price, meaning you could lose money. The fund's investment strategy may not produce the intended results.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;During periods of heightened market volatility or reduced liquidity, governments, their agencies, or other regulatory bodies, both within the United States and abroad, may take steps to intervene. These actions, which could include legislative, regulatory, or economic initiatives, might have unforeseeable consequences and could adversely affect the fund's performance or otherwise constrain the fund's ability to achieve its investment objective.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund's main risks are listed below in alphabetical order. &lt;i&gt;Before investing, be sure to read the additional descriptions of these risks beginning on page 6 of the prospectus.&lt;/i&gt;

               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations.&lt;/div&gt;

               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;

               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: foreign currency forward contracts, futures contracts, variance swaps, options, and swaps. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk. With naked short call positions, the writer of the option may have unlimited liability as the writer may be forced to purchase the stock for delivery at a significantly higher price than the strike price of the option.&lt;/div&gt;

               &lt;b&gt;High portfolio turnover risk.&lt;/b&gt; Trading securities actively and frequently can increase transaction costs (thus lowering performance) and taxable distributions.&lt;/div&gt;

               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;

               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;

               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Warrants risk.&lt;/b&gt; The prices of warrants may not precisely reflect the prices of their underlying securities. Warrant holders do not receive dividends or have voting or credit rights. A warrant ceases to have value if not exercised prior to its expiration date.&lt;/div&gt;

Class A, Class I, and Class R6 shares commenced operations on December 30, 2013. Returns shown prior to a class's commencement date are those of Class NAV shares, except that they include any sales charges. Returns for Class A, Class C, Class I, and Class R6 shares would have been substantially similar to returns of Class NAV shares because each share class is invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.&lt;/div&gt;

The performance presented prior to this date should not be attributed to the current subadvisor. The current portfolio manager has been the lead portfolio manager of the fund since inception. As a result of the difference in subadvisor, the fund's performance shown below might have differed materially.&lt;/div&gt;

You may qualify for sales charge discounts on Class A shares if you and your family invest, or agree to invest in the future, at least $50,000 in the John Hancock family of funds. Intermediaries may have different policies and procedures regarding the availability of front-end sales charge waivers or CDSC waivers (See Appendix 1 - Intermediary sales charge waivers

               ). More information about these and other discounts is available from your financial representative and on pages 20 to 22 of this prospectus under "Sales charge reductions and waivers" or pages 273 to 277 of the fund's Statement of Additional Information under "Sales Charges on Class A, Class B, and Class C Shares."&lt;/div&gt;

Please see below a hypothetical example showing the expenses of a $10,000 investment for the time periods indicated and then, except as shown below, assuming you sell all of your shares at the end of those periods. The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's performance. During its most recent fiscal year, the fund's portfolio turnover rate was 11% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal circumstances, the fund will invest at least 80% of its net assets (plus any borrowings for investment purposes) in companies associated with emerging markets designated from time to time by the Investment Committee of the manager. These emerging markets (Approved Markets) may include frontier markets (early-development emerging markets). A company is associated with an emerging market if its securities meet the definition of "Approved Market Securities," as defined below.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund invests across all market capitalizations with an increased exposure to securities of small-cap issuers and securities the manager considers to be value securities, as described below. The fund invests primarily in Approved Markets equity securities listed on bona fide securities exchanges of any country or actively traded on over-the-counter markets. The fund may invest in financial services companies. The fund also may invest up to 10% of its total assets in shares of other investment companies that invest in one or more Approved Markets, although it intends to do so only where access to those markets is otherwise significantly limited.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The manager primarily considers value stocks to be those with a low price in relation to their book value. The manager may also consider additional factors such as price-to-cash flow or price-to-earnings ratios, as well as economic conditions and developments in the issuer's industry. The criteria used to assess value may change from time to time. The manager may also consider profitability of an eligible company relative to others in making investment decisions. In assessing profitability, the manager may consider ratios such as earnings or profits from operations relative to book value or assets.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;In determining Approved Markets, the manager may consider various factors, including, without limitation, the data, analysis, and classification of countries published or disseminated by the World Bank, the International Finance Corporation, FTSE International, MSCI, and Citigroup. Approved Markets may not include all emerging markets classified by such entities. Other factors the manager may consider include market liquidity, information availability, government regulations (including repatriation rules), and market access, among others.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               The fund may also use derivatives such as futures contracts and options on futures contracts to adjust market exposure based on expected cash inflows to or outflows from the fund. The fund may use derivatives for an Approved Market or other equity market (including U.S.) securities and indexes. The fund may also enter into forward currency contracts to facilitate the settlement of equity purchases of foreign securities, repatriation of foreign currency balances, or currency exchange.            
            &lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;To facilitate seeking broad market diversification, the manager will not use fundamental securities research techniques in selecting securities. The manager retains full discretion with respect to investing in and allocating assets among Approved Markets and issuers associated with them. The fund may focus its investments in a particular sector or sectors of the economy.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;As of the date of this prospectus, the fund considers the following emerging-market countries to be Approved Markets for purposes of its 80% policy described above. In determining when and whether to invest in an Approved Market, the manager may consider factors such as asset growth in the fund and market characteristics. The Investment Committee of the manager may authorize countries for future investment in addition to the countries listed below. The fund may continue to hold investments in countries previously authorized for investment that are not currently authorized.&lt;/div&gt;

               "Approved Market Securities" are defined as securities that are associated with an Approved Market, and include, among others: (a) securities of companies that are organized under the laws of, or maintain their principal place of business in, an Approved Market; (b) securities for which the principal trading market is in an Approved Market; (c) securities issued or guaranteed by the government of an Approved Market country, its agencies or instrumentalities, or the central bank of such country; (d) securities denominated in an Approved Market currency issued by companies to finance operations in Approved Markets; (e) securities of companies that derive at least 50% of their revenues or profits from goods produced or sold, investments made, or services performed in Approved Markets, or have at least 50% of their assets in Approved Markets; (f) Approved Market equity securities in the form of depositary shares; (g) securities of pooled investment vehicles that invest primarily in Approved Markets securities or derivative instruments that derive their value from Approved Market securities; or (h) securities included in the fund's benchmark index. Securities of Approved Markets may include securities of companies that have characteristics and business relationships common to companies in other countries. As a result, the value of the securities of such companies may reflect economic and market forces in such other countries as well as in the Approved Markets. The manager, however, will select only those companies that, in its view, have sufficiently strong exposure to economic and market forces in Approved Markets. For example, the manager may invest in companies organized and located in the United States or other countries outside of Approved Markets, including companies having their entire production facilities outside of Approved Markets, when such companies' securities meet the definition of Approved Market securities.

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Many factors affect performance, and fund shares will fluctuate in price, meaning you could lose money. The fund's investment strategy may not produce the intended results.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;During periods of heightened market volatility or reduced liquidity, governments, their agencies, or other regulatory bodies, both within the United States and abroad, may take steps to intervene. These actions, which could include legislative, regulatory, or economic initiatives, might have unforeseeable consequences and could adversely affect the fund's performance or otherwise constrain the fund's ability to achieve its investment objective.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund's main risks are listed below in alphabetical order. &lt;i&gt;Before investing, be sure to read the additional descriptions of these risks beginning on page 7 of the prospectus.&lt;/i&gt;            
            &lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Currency risk.&lt;/b&gt; Fluctuations in exchange rates may adversely affect the U.S. dollar value of a fund's investments. Foreign currencies may decline in value, which could negatively impact performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Emerging-market risk.&lt;/b&gt; The risks of investing in foreign securities are magnified in emerging markets. Emerging-market countries may experience higher inflation, interest rates, and unemployment and greater social, economic, and political uncertainties than more developed countries.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Financial services sector risk.&lt;/b&gt; Financial services companies can be significantly affected by economic, market, and business developments, borrowing costs, interest-rate fluctuations, competition, and government regulation, among other factors.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Frontier-market risk.&lt;/b&gt; Frontier-market countries generally have smaller economies and less-developed capital markets and political systems than traditional emerging-market countries, which magnifies emerging-market risks.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Greater China risk.&lt;/b&gt; Investments in the Greater China region may be subject to less developed trading markets, acute political risks such as possible negative repercussions resulting from China's relationship with Taiwan or Hong Kong, and restrictions on monetary repatriation or other adverse government actions. For example, a government may restrict investment in companies or industries considered important to national interests, or intervene in the financial markets, such as by imposing trading restrictions, or banning or curtailing short selling. A small number of companies and industries represent a relatively large portion of the Greater China market.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: foreign currency forward contracts, futures contracts, options on futures, and options. Foreign currency forward contracts, futures contracts, and options generally are subject to counterparty risk. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Investment company securities risk.&lt;/b&gt; A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

Past performance (before and after taxes) does not indicate future results. All figures assume dividend reinvestment. Performance information is updated daily, monthly, and quarterly and may be obtained at our website, jhinvestments.com, or by calling 800-225-5291 (Class A and Class C), Monday to Thursday, 8:00 A.M.&#8212;7:00 P.M., and Friday, 8:00 A.M.&#8212;6:00 P.M., Eastern time, or 888-972-8696 (Class I and Class R6) between 8:30 A.M. and 5:00 P.M., Eastern time, on most business days.&lt;/div&gt;

Returns shown prior to a class's commencement date are those of Class NAV shares, except that they include any sales charge. Returns for Class A, Class C, Class I, and Class R6 shares would have been substantially similar to returns of Class NAV shares because each share class is invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.&lt;/div&gt;

Your actual after-tax returns may be different. After-tax returns are not relevant to shares held in an IRA, 401(k), or other tax-advantaged investment plan. After-tax returns for other share classes would vary.&lt;/div&gt;

Please see below a hypothetical example showing the expenses of a $10,000 investment for the time periods indicated and then assuming you sell all of your shares at the end of those periods. The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's performance. During its most recent fiscal year, the fund's portfolio turnover rate was 11% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal circumstances, the fund will invest at least 80% of its net assets (plus any borrowings for investment purposes) in companies associated with emerging markets designated from time to time by the Investment Committee of the manager. These emerging markets (Approved Markets) may include frontier markets (early-development emerging markets). A company is associated with an emerging market if its securities meet the definition of "Approved Market Securities," as defined below.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund invests across all market capitalizations with an increased exposure to securities of small-cap issuers and securities the manager considers to be value securities, as described below. The fund invests primarily in Approved Markets equity securities listed on bona fide securities exchanges of any country or actively traded on over-the-counter markets. The fund may invest in financial services companies. The fund also may invest up to 10% of its total assets in shares of other investment companies that invest in one or more Approved Markets, although it intends to do so only where access to those markets is otherwise significantly limited.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The manager primarily considers value stocks to be those with a low price in relation to their book value. The manager may also consider additional factors such as price-to-cash flow or price-to-earnings ratios, as well as economic conditions and developments in the issuer's industry. The criteria used to assess value may change from time to time. The manager may also consider profitability of an eligible company relative to others in making investment decisions. In assessing profitability, the manager may consider ratios such as earnings or profits from operations relative to book value or assets.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;In determining Approved Markets, the manager may consider various factors, including, without limitation, the data, analysis, and classification of countries published or disseminated by the World Bank, the International Finance Corporation, FTSE International, MSCI, and Citigroup. Approved Markets may not include all emerging markets classified by such entities. Other factors the manager may consider include market liquidity, information availability, government regulations (including repatriation rules), and market access, among others.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               The fund may also use derivatives such as futures contracts and options on futures contracts to adjust market exposure based on expected cash inflows to or outflows from the fund. The fund may use derivatives for an Approved Market or other equity market (including U.S.) securities and indexes. The fund may also enter into forward currency contracts to facilitate the settlement of equity purchases of foreign securities, repatriation of foreign currency balances, or currency exchange.            
            &lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;To facilitate seeking broad market diversification, the manager will not use fundamental securities research techniques in selecting securities. The manager retains full discretion with respect to investing in and allocating assets among Approved Markets and issuers associated with them. The fund may focus its investments in a particular sector or sectors of the economy.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;As of the date of this prospectus, the fund considers the following emerging-market countries to be Approved Markets for purposes of its 80% policy described above. In determining when and whether to invest in an Approved Market, the manager may consider factors such as asset growth in the fund and market characteristics. The Investment Committee of the manager may authorize countries for future investment in addition to the countries listed below. The fund may continue to hold investments in countries previously authorized for investment that are not currently authorized.&lt;/div&gt;

               "Approved Market Securities" are defined as securities that are associated with an Approved Market, and include, among others: (a) securities of companies that are organized under the laws of, or maintain their principal place of business in, an Approved Market; (b) securities for which the principal trading market is in an Approved Market; (c) securities issued or guaranteed by the government of an Approved Market country, its agencies or instrumentalities, or the central bank of such country; (d) securities denominated in an Approved Market currency issued by companies to finance operations in Approved Markets; (e) securities of companies that derive at least 50% of their revenues or profits from goods produced or sold, investments made, or services performed in Approved Markets, or have at least 50% of their assets in Approved Markets; (f) Approved Market equity securities in the form of depositary shares; (g) securities of pooled investment vehicles that invest primarily in Approved Markets securities or derivative instruments that derive their value from Approved Market securities; or (h) securities included in the fund's benchmark index. Securities of Approved Markets may include securities of companies that have characteristics and business relationships common to companies in other countries. As a result, the value of the securities of such companies may reflect economic and market forces in such other countries as well as in the Approved Markets. The manager, however, will select only those companies that, in its view, have sufficiently strong exposure to economic and market forces in Approved Markets. For example, the manager may invest in companies organized and located in the United States or other countries outside of Approved Markets, including companies having their entire production facilities outside of Approved Markets, when such companies' securities meet the definition of Approved Market securities.            
            &lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Many factors affect performance, and fund shares will fluctuate in price, meaning you could lose money. The fund's investment strategy may not produce the intended results.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;During periods of heightened market volatility or reduced liquidity, governments, their agencies, or other regulatory bodies, both within the United States and abroad, may take steps to intervene. These actions, which could include legislative, regulatory, or economic initiatives, might have unforeseeable consequences and could adversely affect the fund's performance or otherwise constrain the fund's ability to achieve its investment objective.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund's main risks are listed below in alphabetical order. &lt;i&gt;Before investing, be sure to read the additional descriptions of these risks beginning on page 7 of the prospectus.&lt;/i&gt;            
            &lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Currency risk.&lt;/b&gt; Fluctuations in exchange rates may adversely affect the U.S. dollar value of a fund's investments. Foreign currencies may decline in value, which could negatively impact performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Emerging-market risk.&lt;/b&gt; The risks of investing in foreign securities are magnified in emerging markets. Emerging-market countries may experience higher inflation, interest rates, and unemployment and greater social, economic, and political uncertainties than more developed countries.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Financial services sector risk.&lt;/b&gt; Financial services companies can be significantly affected by economic, market, and business developments, borrowing costs, interest-rate fluctuations, competition, and government regulation, among other factors.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Frontier-market risk.&lt;/b&gt; Frontier-market countries generally have smaller economies and less-developed capital markets and political systems than traditional emerging-market countries, which magnifies emerging-market risks.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Greater China risk.&lt;/b&gt; Investments in the Greater China region may be subject to less developed trading markets, acute political risks such as possible negative repercussions resulting from China's relationship with Taiwan or Hong Kong, and restrictions on monetary repatriation or other adverse government actions. For example, a government may restrict investment in companies or industries considered important to national interests, or intervene in the financial markets, such as by imposing trading restrictions, or banning or curtailing short selling. A small number of companies and industries represent a relatively large portion of the Greater China market.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: foreign currency forward contracts, futures contracts, options on futures, and options. Foreign currency forward contracts, futures contracts, and options generally are subject to counterparty risk. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Investment company securities risk.&lt;/b&gt; A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The following information illustrates the variability of the fund's returns and provides some indication of the risks of investing in the fund by showing changes in the fund's performance from year to year and by showing how the fund's average annual returns compared with a broad-based market index. Past performance (before and after taxes) does not indicate future results. All figures assume dividend reinvestment. Performance information is updated daily, monthly, and quarterly and may be obtained at our website, jhinvestments.com, or by calling 888-972-8696 between 8:30 A.M. and 5:00 P.M., Eastern time, on most business days.&lt;/div&gt;

Because Class R4 and Class R5 shares had not commenced operations as of the date of this prospectus, the returns shown are those of Class NAV shares. Returns for Class R4 and Class R5 shares would have been substantially similar to returns of Class NAV shares because each share class is invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Please note that after-tax returns (shown for Class R4 shares only) reflect the highest individual federal marginal income-tax rate in effect as of the date provided and do not reflect any state or local taxes. Your actual after-tax returns may be different. After-tax returns are not relevant to shares held in an IRA, 401(k), or other tax-advantaged investment plan. After-tax returns for other share classes would vary.&lt;/div&gt;

Please see below a hypothetical example showing the expenses of a $10,000 investment for the time periods indicated and then, except as shown below, assuming you sell all of your shares at the end of those periods. The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's performance. During its most recent fiscal year, the fund's portfolio turnover rate was 23% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests at least 80% of its net assets in fixed-income securities and debt instruments of emerging-market issuers. The manager may consider, but is not limited to, the classifications by the World Bank, the International Finance Corporation, or the United Nations and its agencies in determining whether a country is an emerging or a developed country. Examples of emerging-market countries include most African, Central Asian, Eastern European, and South and Central American nations.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The manager uses proprietary research to identify specific countries, corporate sectors, and issuers that are attractively priced. The manager's investment decisions are not constrained by market capitalization, company fundamentals, security valuation or seasoning, or similar characteristics. The manager uses economic and industry analysis to try to anticipate shifts in the business cycle. Due to potentially volatile conditions in emerging markets, the fund's portfolio turnover ratio may be higher-than-average, which could increase transaction costs.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in debt securities of any maturity denominated in any currency, including but not limited to: debt issued by governments or government agencies, including the U.S. Treasury; U.S. and foreign corporate-debt instruments; mortgage- and asset-backed securities and collateralized mortgage obligations; and variable and floating-rate senior and subordinated corporate-debt obligations. The fund may invest in countries that do not have sovereign bond ratings or whose bonds are rated below-investment-grade (junk bonds). The fund may invest in corporate or other privately issued debt instruments of issuers with market capitalizations below $1 billion. The fund may attempt to mitigate the risk of unexpected, adverse currency fluctuations through the use of exchange-listed or over-the-counter financial derivatives instruments, including currency forwards, nondeliverable forwards, currency options, interest-rate swaps, interest-rate futures, interest-rate options, index options, and credit default swaps.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is non-diversified and may both invest in a smaller number of issuers and invest more of its assets in the securities of a single issuer than a diversified fund.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Many factors affect performance, and fund shares will fluctuate in price, meaning you could lose money. The fund's investment strategy may not produce the intended results.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;During periods of heightened market volatility or reduced liquidity, governments, their agencies, or other regulatory bodies, both within the United States and abroad, may take steps to intervene. These actions, which could include legislative, regulatory, or economic initiatives, might have unforeseeable consequences and could adversely affect the fund's performance or otherwise constrain the fund's ability to achieve its investment objective.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund's main risks are listed below in alphabetical order. &lt;i&gt;Before investing, be sure to read the additional descriptions of these risks beginning on page 6 of the prospectus.&lt;/i&gt;            
            &lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Changing distribution levels risk.&lt;/b&gt; The fund may cease or reduce the level of its distribution if income or dividends paid from its investments declines.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Emerging-market risk.&lt;/b&gt; The risks of investing in foreign securities are magnified in emerging markets. Emerging-market countries may experience higher inflation, interest rates, and unemployment and greater social, economic, and political uncertainties than more developed countries.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts and swaps, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;High portfolio turnover risk.&lt;/b&gt; Trading securities actively and frequently can increase transaction costs (thus lowering performance) and taxable distributions.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

The example assumes a 5% average annual return and that fund expenses will not change over the periods.

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's performance. During its most recent fiscal year, the fund's portfolio turnover rate was 19% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in equity securities, with at least 65% in common stocks of well-established companies paying above-average dividends. The fund employs a "value" approach and invests in stocks and other securities that appear to be undervalued by various measures but have good prospects for capital appreciation and dividend growth.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, substantial dividend income means that the yield on the fund's portfolio securities generally exceeds the yield on the fund's benchmark. The manager believes that income can contribute significantly to total return over time and expects the fund's yield to exceed that of the Russell 1000 Value Index. While the price of a company's stock can go up or down, stocks paying a high level of dividend income tend to be less volatile than those paying a lower level and may help offset losses in falling markets.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund will generally consider companies with established operating histories, above-average dividend yield or low price/earnings ratios relative to the Russell 1000 Value Index, positive financial characteristics, and/or low stock price relative to a company's underlying value. The fund may also purchase other types of securities in keeping with its objective, including: (i) U.S. dollar-and foreign currency-denominated foreign securities (up to 25% of total assets); (ii) preferred stocks; (iii) convertible stocks, bonds, and warrants; (iv) futures and options; and (v) bank debt, loan participations, and assignments.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in fixed-income securities without regard to quality or rating, including privately negotiated notes or loans (including loan participations and assignments (bank loans)) and up to 10% in below-investment-grade fixed-income securities (junk bonds). The fund's fixed-income investments may include privately negotiated notes or loans, including loan participations and assignments (bank loans). Some loans may be illiquid.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund holds a certain portion of its assets in money market reserves consisting of shares of the T. Rowe Price Government Reserve Fund (or any other internal T. Rowe Price money market fund) or U.S. dollar- and foreign currency-denominated money market securities. These include repurchase agreements in the two highest rating categories that mature in one year or less. The fund may invest reserves in U.S. dollars and foreign currencies.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest up to 10% of its total assets in hybrid instruments. Hybrid instruments are a type of high-risk derivative which can combine the characteristics of securities, futures, and options. Such securities may bear interest or pay dividends at below market rates or even relatively nominal market rates.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;In pursuing the fund's investment objective, the manager may deviate from the fund's normal investment criteria to purchase securities the manager believes might appreciate substantially. The fund may invest significantly in certain sectors, such as the financials sector.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;During periods of heightened market volatility or reduced liquidity, governments, their agencies, or other regulatory bodies, both within the United States and abroad, may take steps to intervene. These actions, which could include legislative, regulatory, or economic initiatives, might have unforeseeable consequences and could adversely affect the fund's performance or otherwise constrain the fund's ability to achieve its investment objective.&lt;/div&gt;

A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;

               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: futures contracts and options. Futures contracts and options generally are subject to counterparty risk.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hybrid instrument risk.&lt;/b&gt; Hybrid instruments entail greater market risk and may be more volatile than traditional debt instruments, may bear interest or pay preferred dividends at below-market rates, and may be illiquid. The risks of investing in hybrid instruments are a combination of the risks of investing in securities, options, futures, and currencies.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Investment company securities risk.&lt;/b&gt; A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Loan participations risk.&lt;/b&gt; Participations and assignments involve special types of risks, including credit risk, interest-rate risk, counterparty risk, liquidity risk, risks associated with extended settlement, and the risks of being a lender.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors. To the extent that a fund invests in securities of companies in the financial services sector, the fund may be significantly affected by economic, market, and business developments, borrowing costs, interest-rate fluctuations, competition, and government regulation, among other factors, impacting that sector.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Warrants risk.&lt;/b&gt; The prices of warrants may not precisely reflect the prices of their underlying securities. Warrant holders do not receive dividends or have voting or credit rights. A warrant ceases to have value if not exercised prior to its expiration date.&lt;/div&gt;

Past performance (before and after taxes) does not indicate future results. The S&amp;amp;P 500 Index shows how the fund's performance compares against the returns and yields of similar investments.

The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's performance. During its most recent fiscal year, the fund's portfolio turnover rate was 19% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in equity securities, with at least 65% in common stocks of well-established companies paying above-average dividends. The fund employs a "value" approach and invests in stocks and other securities that appear to be undervalued by various measures but have good prospects for capital appreciation and dividend growth.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, substantial dividend income means that the yield on the fund's portfolio securities generally exceeds the yield on the fund's benchmark. The manager believes that income can contribute significantly to total return over time and expects the fund's yield to exceed that of the Russell 1000 Value Index. While the price of a company's stock can go up or down, stocks paying a high level of dividend income tend to be less volatile than those paying a lower level and may help offset losses in falling markets.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund will generally consider companies with established operating histories, above-average dividend yield or low price/earnings ratios relative to the Russell 1000 Value Index, positive financial characteristics, and/or low stock price relative to a company's underlying value. The fund may also purchase other types of securities in keeping with its objective, including: (i) U.S. dollar-and foreign currency-denominated foreign securities (up to 25% of total assets); (ii) preferred stocks; (iii) convertible stocks, bonds, and warrants; (iv) futures and options; and (v) bank debt, loan participations, and assignments.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in fixed-income securities without regard to quality or rating, including privately negotiated notes or loans (including loan participations and assignments (bank loans)) and up to 10% in below-investment-grade fixed-income securities (junk bonds). The fund's fixed-income investments may include privately negotiated notes or loans, including loan participations and assignments (bank loans). Some loans may be illiquid.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund holds a certain portion of its assets in money market reserves consisting of shares of the T. Rowe Price Government Reserve Fund (or any other internal T. Rowe Price money market fund) or U.S. dollar- and foreign currency-denominated money market securities. These include repurchase agreements in the two highest rating categories that mature in one year or less. The fund may invest reserves in U.S. dollars and foreign currencies.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest up to 10% of its total assets in hybrid instruments. Hybrid instruments are a type of high-risk derivative which can combine the characteristics of securities, futures, and options. Such securities may bear interest or pay dividends at below market rates or even relatively nominal market rates.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;In pursuing the fund's investment objective, the manager may deviate from the fund's normal investment criteria to purchase securities the manager believes might appreciate substantially. The fund may invest significantly in certain sectors, such as the financials sector.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Many factors affect performance, and fund shares will fluctuate in price, meaning you could lose money. The fund's investment strategy may not produce the intended results.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;During periods of heightened market volatility or reduced liquidity, governments, their agencies, or other regulatory bodies, both within the United States and abroad, may take steps to intervene. These actions, which could include legislative, regulatory, or economic initiatives, might have unforeseeable consequences and could adversely affect the fund's performance or otherwise constrain the fund's ability to achieve its investment objective.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund's main risks are listed below in alphabetical order. &lt;i&gt;Before investing, be sure to read the additional descriptions of these risks beginning on page 5 of the prospectus.&lt;/i&gt;

               &lt;b&gt;Changing distribution levels risk.&lt;/b&gt; The fund may cease or reduce the level of its distribution if income or dividends paid from its investments declines.&lt;/div&gt;

               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Currency risk.&lt;/b&gt; Fluctuations in exchange rates may adversely affect the U.S. dollar value of a fund's investments. Foreign currencies may decline in value, which could negatively impact performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: futures contracts and options. Futures contracts and options generally are subject to counterparty risk.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hybrid instrument risk.&lt;/b&gt; Hybrid instruments entail greater market risk and may be more volatile than traditional debt instruments, may bear interest or pay preferred dividends at below-market rates, and may be illiquid. The risks of investing in hybrid instruments are a combination of the risks of investing in securities, options, futures, and currencies.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Investment company securities risk.&lt;/b&gt; A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Loan participations risk.&lt;/b&gt; Participations and assignments involve special types of risks, including credit risk, interest-rate risk, counterparty risk, liquidity risk, risks associated with extended settlement, and the risks of being a lender.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors. To the extent that a fund invests in securities of companies in the financial services sector, the fund may be significantly affected by economic, market, and business developments, borrowing costs, interest-rate fluctuations, competition, and government regulation, among other factors, impacting that sector.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Warrants risk.&lt;/b&gt; The prices of warrants may not precisely reflect the prices of their underlying securities. Warrant holders do not receive dividends or have voting or credit rights. A warrant ceases to have value if not exercised prior to its expiration date.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The following information illustrates the variability of the fund's returns and provides some indication of the risks of investing in the fund by showing changes in the fund's performance from year to year and by showing how the fund's average annual returns compared with a broad-based market index. Past performance (before and after taxes) does not indicate future results. The S&amp;amp;P 500 Index shows how the fund's performance compares against the returns and yields of similar investments.

Because Class I shares of the fund had not commenced operations as of the date of this prospectus, the returns shown are those of Class NAV shares. Returns for Class I shares would have been substantially similar to returns of Class NAV shares because both share classes are invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.&lt;/div&gt;

The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's performance. During its most recent fiscal year, the fund's portfolio turnover rate was 71% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund will invest at least 80% of its net assets (plus any borrowings for investment purposes) in floating-rate loans, which often include debt securities of domestic and foreign issuers that are rated below investment grade (rated below Baa by a nationally recognized statistical rating organization such as Moody's Investors Service, Inc. or BBB by Standard and Poor's Ratings Services), at the time of purchase, or are of comparable quality, as determined by the manager, and other floating-rate securities. Bonds that are rated at or below BB by Standard and Poor's Ratings Services or Ba by Moody's Investors Service, Inc. are considered junk bonds.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in domestic and foreign loans and loan participations that pay interest at rates that float or reset periodically at a margin above a generally recognized base lending rate such as the Prime Rate, the London InterBank Offered Rate (LIBOR), or another generally recognized base lending rate. Loans and debt instruments rated below investment grade are considered speculative. The fund may invest in loans of companies whose financial conditions are troubled or uncertain and that may be involved in bankruptcy proceedings, reorganizations, or financial restructurings. Some loans may be illiquid. The fund may also acquire and hold warrants and other equity interests. The fund may invest in loans, loan participations, and other securities of any maturity and duration. The fund may also invest in loans of any aggregate principal amount, which will vary from time to time.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;For purposes of reducing risk and/or improving liquidity, the fund may invest in derivative instruments such as options (including options on securities indexes) and swaps (including credit default swaps).&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in any number of issuers and may, at times, invest its assets in a small number of issuers. The fund may focus its investments in a particular sector or sectors of the economy. The fund's investment process may result in a higher-than-average portfolio turnover ratio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Many factors affect performance, and fund shares will fluctuate in price, meaning you could lose money. The fund's investment strategy may not produce the intended results.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;During periods of heightened market volatility or reduced liquidity, governments, their agencies, or other regulatory bodies, both within the United States and abroad, may take steps to intervene. These actions, which could include legislative, regulatory, or economic initiatives, might have unforeseeable consequences and could adversely affect the fund's performance or otherwise constrain the fund's ability to achieve its investment objective.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund's main risks are listed below in alphabetical order. &lt;i&gt;Before investing, be sure to read the additional descriptions of these risks beginning on page 6 of the prospectus.&lt;/i&gt;

               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;

               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;

               &lt;b&gt;Distressed investments risk.&lt;/b&gt; Distressed investments, including loans, mortgages, bonds, and notes, may not be publicly traded and may involve substantial risk. A fund may lose up to its entire investment.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. &lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, options, and swaps. Options and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;High portfolio turnover risk.&lt;/b&gt; Trading securities actively and frequently can increase transaction costs (thus lowering performance) and taxable distributions.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;

               &lt;b&gt;Loan participations risk.&lt;/b&gt; Participations and assignments involve special types of risks, including credit risk, interest-rate risk, counterparty risk, liquidity risk, risks associated with extended settlement, and the risks of being a lender.&lt;/div&gt;

               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small number of issuers risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for funds which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;

               &lt;b&gt;Warrants risk.&lt;/b&gt; The prices of warrants may not precisely reflect the prices of their underlying securities. Warrant holders do not receive dividends or have voting or credit rights. A warrant ceases to have value if not exercised prior to its expiration date.&lt;/div&gt;

Performance information is updated daily, monthly, and quarterly and may be obtained at our website, jhinvestments.com, or by calling 800-225-5291(Class A, Class B, and Class C), Monday to Thursday, 8:00 A.M.&#8212;7:00 P.M., and Friday, 8:00 A.M.&#8212;6:00 P.M., Eastern time, or 888-972-8696 (Class I and Class R6) between 8:30 A.M. and 5:00 P.M., Eastern time, on most business days.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;A note on performance&lt;/b&gt;            
            &lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Class C and Class R6 shares commenced operations on January 2, 2008 and September 1, 2011, respectively. Returns shown prior to Class R6 shares' commencement date are those of Class C shares, except that they do not include sales charges and would be lower if they did.  Returns for Class R6 shares would have been substantially similar to returns of Class C shares because both share classes are invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Prior to August 30, 2018, the fund was managed by a different subadvisor and thus, the performance  presented prior to August 30, 2018 should not be attributed to the current subadvisor, BCSF  Advisors, LP (Bain Capital Credit). The fund's performance shown below might have differed materially had Bain Capital Credit managed the fund prior to August 30, 2018.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Please note that after-tax returns (shown for Class A shares only) reflect the highest individual federal marginal income-tax rate in effect as of the date provided and do not reflect any state or local taxes. Your actual after-tax returns may be different. After-tax returns are not relevant to shares held in an IRA, 401(k), or other tax-advantaged investment plan. The returns for Class A shares have been adjusted to reflect the reduction in the maximum sales charge from 3.00% to 2.50%, effective February 3, 2014. After-tax returns for other share classes would vary.&lt;/div&gt;

The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's performance. During its most recent fiscal year, the fund's portfolio turnover rate was 40% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund will invest at least 80% of its net assets (plus any borrowings for investment purposes) in securities of franchise companies. A franchise company is one whose return on invested capital over a three-year period is above its cost of capital. Return on invested capital quantifies how well a company generates cash flow relative to the capital it has invested in its business, while its cost of capital refers to the cost of raising money to fund its business. These companies will have a leading share of industry sales, the ability to generate consistent sales growth over time as their products and services attract a larger customer base, and a strong record of return on capital invested in the company with a sustainable competitive advantage, meaning bargaining power with buyers and/or sellers and a unique product or process that is difficult to replicate or substitute and hard for others to compete with.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, at least 40% of the value of the fund's net assets will be invested in issuers domiciled outside of the United States, which includes securities for which the relevant reference entity is domiciled outside the United States, such as American Depositary Receipts (ADRs) that trade on U.S. exchanges.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The manager's primary method of analysis is fundamental analysis, which is the ability to assess the health of a company, its competitive positioning, its strength of management, and its competitive advantages. Investment decisions are a function of finding stocks that possess the qualitative factors as outlined above and the manager believes are trading at a significant discount to the manager's estimation of value.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is a non-diversified fund, which means that it may invest in a smaller number of issuers than a diversified fund and may invest more of its assets in the securities of a single issuer.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest significantly in securities of companies in certain sectors, such as the consumer staples and consumer discretionary sectors (as defined by the Global Industry Classification Standards (GICS)), and may therefore experience greater volatility than funds investing in a broader range of sectors and may be more susceptible to the impact of market, economic, regulatory, and other factors affecting that sector.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The manager focuses on the equity securities of small-, mid-, and large-capitalization companies in both developed and emerging countries. The manager primarily invests in common stocks of developed and emerging companies, as well as ADRs, which trade on U.S. exchanges.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Many factors affect performance, and fund shares will fluctuate in price, meaning you could lose money. The fund's investment strategy may not produce the intended results.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;During periods of heightened market volatility or reduced liquidity, governments, their agencies, or other regulatory bodies, both within the United States and abroad, may take steps to intervene. These actions, which could include legislative, regulatory, or economic initiatives, might have unforeseeable consequences and could adversely affect the fund's performance or otherwise constrain the fund's ability to achieve its investment objective.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund's main risks are listed below in alphabetical order. &lt;i&gt;Before investing, be sure to read the additional descriptions of these risks beginning on page 5 of the prospectus.&lt;/i&gt;

               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;

               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The following information illustrates the variability of the fund's returns and provides some indication of the risks of investing in the fund by showing changes in the fund's performance from year to year and by showing how the fund's average annual returns compared with a broad-based market index. Past performance (before and after taxes) does not indicate future results. All figures assume dividend reinvestment. Performance information is updated daily, monthly, and quarterly and may be obtained at our website, jhinvestments.com, or by calling 800-225-5291 (Class A shares), Monday to Thursday, 8:00 A.M.&#8212;7:00 P.M., and Friday, 8:00 A.M.&#8212;6:00 P.M., Eastern time, or 888-972-8696 (Class I and Class R6) between 8:30 A.M. and 5:00 P.M., Eastern time, on most business days.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Class A and Class R6 shares commenced operations on June 29, 2012 and February 13, 2017, respectively. Returns shown prior to Class R6 shares' commencement date are those of Class A shares, except that they do not include sales charges and would be lower if they did. Returns for Class R6 shares would have been substantially similar to returns of Class A shares because both share classes are invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Please note that after-tax returns (shown for Class A shares only) reflect the highest individual federal marginal income-tax rate in effect as of the date provided and do not reflect any state or local taxes. Your actual after-tax returns may be different. After-tax returns are not relevant to shares held in an IRA, 401(k), or other tax-advantaged investment plan. After-tax returns for other share classes would vary.&lt;/div&gt;

You may qualify for sales charge discounts on Class A shares if you and your family invest, or agree to invest in the future, at least $50,000 in the John Hancock family of funds. Intermediaries may have different policies and procedures regarding the availability of front-end sales charge waivers or CDSC waivers (See Appendix 1 - Intermediary sales charge waivers

Please see below a hypothetical example showing the expenses of a $10,000 investment for the time periods indicated and then, except as shown below, assuming you sell all of your shares at the end of those periods. The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's performance. During its most recent fiscal year, the fund's portfolio turnover rate was 43% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund seeks to generate capital appreciation by investing at least 80% of net assets (plus borrowings for investment purposes) in a diversified portfolio of equity securities. Under normal market conditions, at least 40% of the value of the fund's net assets will be invested in securities of issuers domiciled outside of the United States, including in emerging markets. This includes securities of foreign issuers that trade on U.S. exchanges. Equity securities include common and preferred stocks and their equivalents, including depositary receipts, warrants, rights, and convertible securities. The fund may invest in securities of any market-capitalization.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The manager employs an unconstrained, bottom-up stock selection process based on fundamental research to attempt to identify undervalued companies that exhibit attractive valuations, solid business franchises, sustainable margins/cash flow, disciplined capital allocation, strong management teams, and strong balance sheets. The manager considers diversification benefits and liquidity of the security in making investment decisions.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Many factors affect performance, and fund shares will fluctuate in price, meaning you could lose money. The fund's investment strategy may not produce the intended results.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;During periods of heightened market volatility or reduced liquidity, governments, their agencies, or other regulatory bodies, both within the United States and abroad, may take steps to intervene. These actions, which could include legislative, regulatory, or economic initiatives, might have unforeseeable consequences and could adversely affect the fund's performance or otherwise constrain the fund's ability to achieve its investment objective.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund's main risks are listed below in alphabetical order. &lt;i&gt;Before investing, be sure to read the additional descriptions of these risks beginning on page 5 of the prospectus.&lt;/i&gt;            
            &lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Emerging-market risk.&lt;/b&gt; The risks of investing in foreign securities are magnified in emerging markets. Emerging-market countries may experience higher inflation, interest rates, and unemployment and greater social, economic, and political uncertainties than more developed countries.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Warrants risk.&lt;/b&gt; The prices of warrants may not precisely reflect the prices of their underlying securities. Warrant holders do not receive dividends or have voting or credit rights. A warrant ceases to have value if not exercised prior to its expiration date.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 50% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund has significant flexibility to achieve its investment objective and invests in a broad range of income-producing securities, affiliated and unaffiliated underlying funds, and exchange-traded funds (ETFs). The fund may invest directly in debt and equity securities, in underlying funds, in derivative instruments, or in any combination thereof without limitations other than those stated below. The allocation of the fund's investments will vary and, at any given time, the fund may not be invested in all the types of securities and other investments described below.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in the U.S. and foreign markets, including emerging markets. Investments may be in any currency and may be currency-hedged or unhedged. There is no limit on the number of countries in which the fund may invest, and the fund may focus its investments in a single country or a small group of countries. The manager has wide latitude to allocate the fund's assets among strategies and asset classes. Investment decisions are based on the manager's views of strategies, sectors, and overall portfolio construction, taking into account income generation, risk/return analyses, and relative value considerations. The fund may invest up to 100% of its assets in fixed-income securities and up to 70% of its assets in equity securities.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in a portfolio of fixed-income securities such as corporate bonds and notes, government obligations, and mortgage- and asset-backed, convertible, and preferred securities. The fund may also invest in common and preferred stock, securities convertible into common and preferred stock, and non-convertible preferred stock and ETFs, as well as fixed-income and equity funds and ETFs. The fund may also invest significantly in below-investment-grade bonds (e.g., high-yield bonds, junk bonds, or arbitrage and distressed securities) and bank loans, foreign currency-denominated bonds, and bonds of emerging-market issuers. Some loans may be illiquid. The fund may invest in other investment companies, including closed-end funds. Below-investment-grade bonds acquired by the fund directly or through underlying funds will generally be rated BB or lower by Standard &amp;amp; Poor's Ratings Services, Ba or lower by Moody's Investors Service, or of similar quality if unrated. There are no limits regarding portfolio duration or average maturity and average duration will vary.  The fund generally intends to invest in dividend-paying stocks. The fund may invest through initial public offerings (IPOs) and in securities of companies of any market capitalization.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund also may invest extensively in derivative instruments such as futures, options, and swaps, which may relate to equity securities, fixed-income securities, interest rates, total return rates, currencies or currency exchange rates, among other things, and may be used to hedge against losses from movements in stock, currency exchange rates or interest rates or for other hedging purposes, to invest indirectly in securities or financial markets, for duration management, to gain exposure to foreign currencies, for efficient portfolio management, or to generate income. The fund also may invest in restricted or illiquid securities. The fund also may invest in alternative or non traditional asset categories such as commodities, market neutral (long/short) strategies, global real estate, natural resources, TIPS (Treasury Inflation-Protected Securities), foreign currency trading strategies, managed futures, arbitrage strategies, and tactical investment strategies. These investments may be made either directly or through exchange-traded notes (ETNs) or investment companies, including ETFs.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund and/or the underlying funds may trade securities actively, which could result in a high portfolio turnover ratio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Many factors affect performance, and fund shares will fluctuate in price, meaning you could lose money. The fund's investment strategy may not produce the intended results.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;During periods of heightened market volatility or reduced liquidity, governments, their agencies, or other regulatory bodies, both within the United States and abroad, may take steps to intervene. These actions, which could include legislative, regulatory, or economic initiatives, might have unforeseeable consequences and could adversely affect the fund's performance or otherwise constrain the fund's ability to achieve its investment objective.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund's main risks are listed below in alphabetical order. &lt;i&gt;Before investing, be sure to read the additional descriptions of these risks beginning on page 7 of the prospectus.&lt;/i&gt;            
            &lt;/div&gt;

               &lt;b&gt;Arbitrage securities and distressed companies risk.&lt;/b&gt; A merger or other restructuring, tender offer, or exchange offer proposed or pending at the time of investment in risk arbitrage securities may not be completed on the terms contemplated, resulting in losses.&lt;/div&gt;

               &lt;b&gt;Asset allocation risk.&lt;/b&gt; Although allocation among asset categories generally limits exposure to any one category, the management team may favor a category that performs poorly relative to others. Alternative asset categories may underperform the general stock market.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;

               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;

               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;High portfolio turnover risk.&lt;/b&gt; Trading securities actively and frequently can increase transaction costs (thus lowering performance) and taxable distributions.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Investment company securities risk.&lt;/b&gt; A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;

               &lt;b&gt;Loan participations risk.&lt;/b&gt; Participations and assignments involve special types of risks, including credit risk, interest-rate risk, counterparty risk, liquidity risk, risks associated with extended settlement, and the risks of being a lender.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Natural resources industry risk.&lt;/b&gt; The natural resources industry can be significantly affected by international political and economic developments, energy conservation and exploration efforts, commodity prices, and taxes and other governmental regulations, among other factors.&lt;/div&gt;

               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;

               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;

               &lt;b&gt;Real estate securities risk.&lt;/b&gt; Securities of companies in the real estate industry carry risks associated with owning real estate, including the potential for a decline in value due to economic or market conditions.&lt;/div&gt;

               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;

               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

The example assumes a 5% average annual return and that fund expenses will not change over the periods.

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's performance. During its most recent fiscal year, the fund's portfolio turnover rate was 19% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in securities of small-cap companies in the particular markets in which the fund invests. Based on market capitalization data as of October 31, 2018, the maximum market capitalization range of companies eligible for purchase by the fund was approximately $1.7 billion to $6.2 billion, depending on the country. The fund will primarily invest in a broad and diverse group of equity securities of foreign small companies in developed markets, but may also hold equity securities of companies located in emerging markets.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund invests its assets in securities listed on bona fide securities exchanges or traded on the over-the-counter markets, including dual-listed securities, either within or outside the issuer's domicile country.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The manager measures company size on a country- or region-specific basis and based primarily on market capitalization. In the countries or regions authorized for investment, the manager first ranks eligible companies based on market capitalizations and then determines the universe of eligible stocks by defining the maximum market capitalization of a small company that may be purchased by the fund with respect to each country or region. These thresholds will vary based on market conditions. The fund intends to use a market-capitalization-weighted approach in seeking to set country weights based on the relative market capitalizations of eligible small companies within each country (see below). Weightings of certain countries may vary from their weightings in international indices.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may also use derivatives such as futures contracts and options on futures contracts to adjust market exposure based on expected cash inflows to or outflows from the fund. Futures contracts and options on futures contracts may be for foreign or U.S. equity securities and indexes. The fund may also enter into forward currency contracts to facilitate settlement of equity purchases of foreign securities, repatriation of foreign currency balances, or currency exchange. In addition to cash, money market instruments, and other short-term investments, the fund may invest in affiliated and unaffiliated unregistered money market funds to manage cash pending investment, to maintain liquidity to pay redemptions, to make other anticipated cash payments, or for other purposes. Investments in money market funds may involve a duplication of certain fees and expenses.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund does not seek current income as an investment objective and investments will not be based on an issuer's dividend payment policy or record, although many of the companies in which the fund invests do pay dividends.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The manager may, in its discretion, invest in countries authorized by its Investment Committee, depending upon factors such as asset growth in the fund and market characteristics. Other countries may be authorized for investment in the future, and the fund may continue to hold investments in countries previously but not currently authorized. The fund may focus its investments in a particular sector or sectors of the economy.&lt;/div&gt;

                  Market-capitalization-weighted approach

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund uses market capitalization weighting to determine individual security weights and, where applicable, country or region weights. Market-capitalization weighting means each security is generally purchased based on the issuer's relative market capitalization. Market-capitalization weighting will be adjusted by the manager for a variety of factors, including free float, momentum, trading strategies, liquidity management, profitability, and market conditions, among others. The manager may deviate from market-capitalization weighting to limit or fix the exposure of the fund to a particular country or issuer to a maximum proportion of fund assets and may exclude the stock of a company that meets applicable market-capitalization criteria at its discretion. These adjustments will result in a deviation from traditional market-capitalization weighting.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Country weights may be based on the total market capitalization of companies within each country and may take into consideration the free float of companies within a country or whether these companies are eligible to be purchased for the particular strategy. In addition, to maintain a satisfactory level of diversification, the Investment Committee may limit or adjust the exposure to a particular country or region to a maximum proportion of the assets of that vehicle. Country weights may also vary due to general day-to-day trading patterns and price movements.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Many factors affect performance, and fund shares will fluctuate in price, meaning you could lose money. The fund's investment strategy may not produce the intended results.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;During periods of heightened market volatility or reduced liquidity, governments, their agencies, or other regulatory bodies, both within the United States and abroad, may take steps to intervene. These actions, which could include legislative, regulatory, or economic initiatives, might have unforeseeable consequences and could adversely affect the fund's performance or otherwise constrain the fund's ability to achieve its investment objective.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund's main risks are listed below in alphabetical order. &lt;i&gt;Before investing, be sure to read the additional descriptions of these risks beginning on page 7 of the prospectus.&lt;/i&gt;            
            &lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: foreign currency forward contracts, futures contracts, options on futures contracts, and options. Foreign currency forward contracts, futures contracts, and options generally are subject to counterparty risk. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Investment company securities risk.&lt;/b&gt; A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

Returns shown prior to a class's commencement date are those of Class NAV shares, except that they include any sales charges. Returns for Class A, Class C, Class I, and Class R6 shares would have been substantially similar to returns of Class NAV shares because each share class is invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.&lt;/div&gt;

Your actual after-tax returns may be different. After-tax returns are not relevant to shares held in an IRA, 401(k), or other tax-advantaged investment plan. After-tax returns for other share classes would vary.&lt;/div&gt;

Please see below a hypothetical example showing the expenses of a $10,000 investment for the time periods indicated and then assuming you sell all of your shares at the end of those periods. The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's performance. During its most recent fiscal year, the fund's portfolio turnover rate was 19% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in securities of small-cap companies in the particular markets in which the fund invests. Based on market capitalization data as of October 31, 2018, the maximum market capitalization range of companies eligible for purchase by the fund was approximately $1.7 billion to $6.2 billion, depending on the country. The fund will primarily invest in a broad and diverse group of equity securities of foreign small companies in developed markets, but may also hold equity securities of companies located in emerging markets.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund invests its assets in securities listed on bona fide securities exchanges or traded on the over-the-counter markets, including dual-listed securities, either within or outside the issuer's domicile country.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The manager measures company size on a country- or region-specific basis and based primarily on market capitalization. In the countries or regions authorized for investment, the manager first ranks eligible companies based on market capitalizations and then determines the universe of eligible stocks by defining the maximum market capitalization of a small company that may be purchased by the fund with respect to each country or region. These thresholds will vary based on market conditions. The fund intends to use a market-capitalization-weighted approach in seeking to set country weights based on the relative market capitalizations of eligible small companies within each country (see below). Weightings of certain countries may vary from their weightings in international indices.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may also use derivatives such as futures contracts and options on futures contracts to adjust market exposure based on expected cash inflows to or outflows from the fund. Futures contracts and options on futures contracts may be for foreign or U.S. equity securities and indexes. The fund may also enter into forward currency contracts to facilitate settlement of equity purchases of foreign securities, repatriation of foreign currency balances, or currency exchange. In addition to cash, money market instruments, and other short-term investments, the fund may invest in affiliated and unaffiliated unregistered money market funds to manage cash pending investment, to maintain liquidity to pay redemptions, to make other anticipated cash payments, or for other purposes. Investments in money market funds may involve a duplication of certain fees and expenses.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund does not seek current income as an investment objective and investments will not be based on an issuer's dividend payment policy or record, although many of the companies in which the fund invests do pay dividends.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The manager may, in its discretion, invest in countries authorized by its Investment Committee, depending upon factors such as asset growth in the fund and market characteristics. Other countries may be authorized for investment in the future, and the fund may continue to hold investments in countries previously but not currently authorized. The fund may focus its investments in a particular sector or sectors of the economy.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Market-capitalization-weighted approach&lt;/b&gt;            
            &lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund uses market capitalization weighting to determine individual security weights and, where applicable, country or region weights. Market-capitalization weighting means each security is generally purchased based on the issuer's relative market capitalization. Market-capitalization weighting will be adjusted by the manager for a variety of factors, including free float, momentum, trading strategies, liquidity management, profitability, and market conditions, among others. The manager may deviate from market-capitalization weighting to limit or fix the exposure of the fund to a particular country or issuer to a maximum proportion of fund assets and may exclude the stock of a company that meets applicable market-capitalization criteria at its discretion. These adjustments will result in a deviation from traditional market-capitalization weighting.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Country weights may be based on the total market capitalization of companies within each country and may take into consideration the free float of companies within a country or whether these companies are eligible to be purchased for the particular strategy. In addition, to maintain a satisfactory level of diversification, the Investment Committee may limit or adjust the exposure to a particular country or region to a maximum proportion of the assets of that vehicle. Country weights may also vary due to general day-to-day trading patterns and price movements.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Many factors affect performance, and fund shares will fluctuate in price, meaning you could lose money. The fund's investment strategy may not produce the intended results.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;During periods of heightened market volatility or reduced liquidity, governments, their agencies, or other regulatory bodies, both within the United States and abroad, may take steps to intervene. These actions, which could include legislative, regulatory, or economic initiatives, might have unforeseeable consequences and could adversely affect the fund's performance or otherwise constrain the fund's ability to achieve its investment objective.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund's main risks are listed below in alphabetical order. &lt;i&gt;Before investing, be sure to read the additional descriptions of these risks beginning on page 6 of the prospectus.&lt;/i&gt;            
            &lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: foreign currency forward contracts, futures contracts, options on futures contracts, and options. Foreign currency forward contracts, futures contracts, and options generally are subject to counterparty risk. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Investment company securities risk.&lt;/b&gt; A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The following information illustrates the variability of the fund's returns and provides some indication of the risks of investing in the fund by showing changes in the fund's performance from year to year and by showing how the fund's average annual returns compared with a broad-based market index. Past performance (before and after taxes) does not indicate future results. The MSCI EAFE Small Cap Index shows how the fund's performance compares against the returns of similar investments.

Because Class R2, Class R4, and Class R5 shares of the fund had not commenced operations as of the date of this prospectus, the returns shown are those of Class NAV shares. Returns for Class R2, Class R4, and Class R5 shares would have been substantially similar to returns of Class NAV shares because each share class is invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.&lt;/div&gt;

Your actual after-tax returns may be different. After-tax returns are not relevant to shares held in an IRA, 401(k), or other tax-advantaged investment plan. After-tax returns for other share classes would vary.&lt;/div&gt;

More information about these and other discounts is available from your financial representative and on pages 54 to 56 of this prospectus under "Sales charge reductions and waivers" or pages 273 to 276 of the fund's Statement of Additional Information under "Sales Charges on Class A, Class B, and Class C Shares."&lt;/div&gt;

The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 15% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund operates as a fund of funds and, except as otherwise described below, normally invests approximately 100% of its assets in underlying funds that invest primarily in equity securities. Underlying funds may be affiliated or unaffiliated and may include exchange-traded funds (ETFs).&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Variations in the target percentage allocation between underlying funds that invest primarily in equity securities and underlying funds that invest primarily in fixed-income securities are permitted up to 10%. There is no limit on the range of maturities and credit quality of securities in which the fund and underlying funds may invest. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from short to longer term. The fixed-income underlying funds collectively hold various types of debt instruments, such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging-market securities). The portfolio managers may exceed the normal percentage limitations to protect the fund or seek to achieve its goal in light of market or economic conditions.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in various passively managed underlying funds that, as a group, hold a wide range of equity-type securities. The fund may also invest in various actively managed underlying funds. The fund is not designed to track an index or group of indexes. Equity-type securities include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. Each of the underlying funds has its own investment strategy that, for example, may focus on growth stocks, value stocks, or a combination of growth and income stocks. Underlying funds may invest in derivatives such as options on securities and futures contracts.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may also invest in derivatives such as credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, as well as in exchange-traded notes (ETNs). The fund may also purchase futures contracts for cash management purposes and to gain investment exposure pending investments.). The fund is also authorized to use various other investment strategies such as investing directly in fixed-income and equity securities, including U.S. government securities, mortgage-backed and asset-backed securities, closed-end funds, and partnerships. The fund may also short-sell securities.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The investment performance of each fund will reflect both its managers' allocation decisions with respect to the underlying funds and the investment decisions made by the underlying funds' managers.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Many factors affect performance, and fund shares will fluctuate in price, meaning you could lose money. The fund's investment strategy may not produce the intended results.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;During periods of heightened market volatility or reduced liquidity, governments, their agencies, or other regulatory bodies, both within the United States and abroad, may take steps to intervene. These actions, which could include legislative, regulatory, or economic initiatives, might have unforeseeable consequences and could adversely affect the fund's performance or otherwise constrain the fund's ability to achieve its investment objective.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in equity securities than John Hancock Multi-Index Lifestyle Portfolios with greater target allocations to underlying funds that invest primarily in fixed-income securities, equity security risks are more prevalent in this fund than in other John Hancock Multi-Index Lifestyle Portfolios. In addition to equity securities risk, the fund's other main risk factors are listed below in alphabetical order. &lt;i&gt;Before investing, be sure to read the additional descriptions of these risks beginning on page 32 of the prospectus.&lt;/i&gt;

                 &lt;i&gt; Principal risks of investing in the fund of funds  &lt;/i&gt;             
               &lt;/b&gt;&lt;/div&gt;             
                     
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Investment company securities risk.&lt;/b&gt; A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Short sales risk.&lt;/b&gt; In a short sale, a fund pays interest on the borrowed security. The fund will lose money if the security price increases between the short sale and the replacement date.&lt;/div&gt;         
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
               &lt;i&gt;   Principal risks of investing in the underlying funds    &lt;/i&gt;           
               &lt;/b&gt;&lt;/div&gt;             
                     
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;

Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide.

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations.

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The following information illustrates the variability of the fund's returns and provides some indication of the risks of investing in the fund by showing changes in the fund's performance from year to year and by showing how the fund's average annual returns compared with a broad-based market index. Past performance (before and after taxes) does not indicate future results. All figures assume dividend reinvestment. The fund's custom blended benchmark comprises 70% Russell 3000 Index/30% MSCI ACWI ex-USA Index and shows how the fund's performance compares against the returns of similar investments. Performance information is updated daily, monthly, and quarterly and may be obtained at our website, jhinvestments.com, or by calling 800-225-5291 (Class A), Monday to Thursday, 8:00 A.M.&#8212;7:00 P.M., and Friday, 8:00 A.M.&#8212;6:00 P.M., Eastern time, or 888-972-8696 (Class I, Class R2, Class R4, and Class R5) between 8:30 A.M. and 5:00 P.M., Eastern time, on most business days.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Class 1 shares commenced operations on December 30, 2013.  Because Class A, Class I, Class R2, Class R4, and Class R5 shares of the fund had not commenced operations as of the date of this prospectus, the returns shown are those of Class 1 shares, except that they include any sales charges. Returns for Class A, Class I, Class R2, Class R4, and Class R5 shares would have been substantially similar to returns of Class 1 shares because each share class is invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Please note that after-tax returns (shown for Class A shares only) reflect the highest individual federal marginal income-tax rate in effect as of the date provided and do not reflect any state or local taxes. Your actual after-tax returns may be different. After-tax returns are not relevant to shares held in an IRA, 401(k), or other tax-advantaged investment plan. After-tax returns for other share classes would vary.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 17% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund operates as a fund of funds and, except as otherwise described below, normally invests approximately 40% of its assets in underlying funds that invest primarily in fixed-income securities and approximately 60% of its assets in underlying funds that invest primarily in equity securities. Underlying funds may be affiliated or unaffiliated and may include exchange-traded funds (ETFs).&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Variations in the target percentage allocation between underlying funds that invest primarily in equity securities and underlying funds that invest primarily in fixed-income securities are permitted up to 10%. There is no limit on the range of maturities and credit quality of securities in which the fund and underlying funds may invest. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from short to longer term. The fixed-income underlying funds collectively hold various types of debt instruments, such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging-market securities). The portfolio managers may exceed the normal percentage limitations to protect the fund or seek to achieve its goal in light of market or economic conditions.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in various passively managed underlying funds that, as a group, hold a wide range of equity-type securities. The fund may also invest in various actively managed underlying funds. The fund is not designed to track an index or group of indexes. Equity-type securities include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. Each of the underlying funds has its own investment strategy that, for example, may focus on growth stocks, value stocks, or a combination of growth and income stocks. Underlying funds may invest in derivatives such as options on securities and futures contracts.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may also invest in derivatives such as credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, as well as in exchange-traded notes (ETNs). The fund may also purchase futures contracts for cash management purposes and to gain investment exposure pending investments.). The fund is also authorized to use various other investment strategies such as investing directly in fixed-income and equity securities, including U.S. government securities, mortgage-backed and asset-backed securities, closed-end funds, and partnerships. The fund may also short-sell securities.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The investment performance of each fund will reflect both its managers' allocation decisions with respect to the underlying funds and the investment decisions made by the underlying funds' managers.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Many factors affect performance, and fund shares will fluctuate in price, meaning you could lose money. The fund's investment strategy may not produce the intended results.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;During periods of heightened market volatility or reduced liquidity, governments, their agencies, or other regulatory bodies, both within the United States and abroad, may take steps to intervene. These actions, which could include legislative, regulatory, or economic initiatives, might have unforeseeable consequences and could adversely affect the fund's performance or otherwise constrain the fund's ability to achieve its investment objective.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in equity securities than John Hancock Multi-Index Lifestyle Portfolios with greater target allocations to underlying funds that invest primarily in fixed-income securities, equity security risks are more prevalent in this fund than in other John Hancock Multi-Index Lifestyle Portfolios. In addition to equity securities risk, the fund's other main risk factors are listed below in alphabetical order. &lt;i&gt;Before investing, be sure to read the additional descriptions of these risks beginning on page 32 of the prospectus.&lt;/i&gt;

               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;

               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;

               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions.&lt;/div&gt;

               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;

               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;

               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Short sales risk.&lt;/b&gt; In a short sale, a fund pays interest on the borrowed security. The fund will lose money if the security price increases between the short sale and the replacement date.&lt;/div&gt;

                  Principal risks of investing in the underlying funds   &lt;/i&gt;            
               &lt;/b&gt;&lt;/div&gt;

               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The following information illustrates the variability of the fund's returns and provides some indication of the risks of investing in the fund by showing changes in the fund's performance from year to year and by showing how the fund's average annual returns compared with a broad-based market index. Past performance (before and after taxes) does not indicate future results. All figures assume dividend reinvestment. The fund's custom blended benchmark comprises 42% Russell 3000 Index/18% MSCI ACWI ex-USA Index/32% Bloomberg Barclays U.S. Aggregate Bond Index/8% ICE Bank of America Merrill Lynch U.S. High Yield Master II Index and shows how the fund's performance compares against the returns of similar investments. Performance information is updated daily, monthly, and quarterly and may be obtained at our website, jhinvestments.com, or by calling 800-225-5291 (Class A), Monday to Thursday, 8:00 A.M.&#8212;7:00 P.M., and Friday, 8:00 A.M.&#8212;6:00 P.M., Eastern time, or 888-972-8696 (Class I, Class R2, Class R4, and Class R5) between 8:30 A.M. and 5:00 P.M., Eastern time, on most business days.&lt;/div&gt;

Because Class A, Class I, Class R2, Class R4, and Class R5 shares of the fund had not commenced operations as of the date of this prospectus, the returns shown are those of Class 1 shares, except that they include any sales charges. Returns for Class A, Class I, Class R2, Class R4, and Class R5 shares would have been substantially similar to returns of Class 1 shares because each share class is invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.&lt;/div&gt;

Your actual after-tax returns may be different. After-tax returns are not relevant to shares held in an IRA, 401(k), or other tax-advantaged investment plan.

Intermediaries may have different policies and procedures regarding the availability of front-end sales charge waivers or CDSC waivers (See Appendix 1 - Intermediary sales charge waivers, which includes information about specific sales charge waivers applicable to the intermediaries identified therein). More information about these and other discounts is available from your financial representative and on pages 54 to 56 of this prospectus under "Sales charge reductions and waivers" or pages 273 to 276 of the fund's Statement of Additional Information under "Sales Charges on Class A, Class B, and Class C Shares."&lt;/div&gt;

The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 24% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund operates as a fund of funds and, except as otherwise described below, normally invests approximately 80% of its assets in underlying funds that invest primarily in fixed-income securities and approximately 20% in underlying funds that invest primarily in equity securities. Underlying funds may be affiliated or unaffiliated and may include exchange-traded funds (ETFs).&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Variations in the target percentage allocation between underlying funds that invest primarily in equity securities and underlying funds that invest primarily in fixed-income securities are permitted up to 10%. There is no limit on the range of maturities and credit quality of securities in which the fund and underlying funds may invest. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from short to longer term. The fixed-income underlying funds collectively hold various types of debt instruments, such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging-market securities). The portfolio managers may exceed the normal percentage limitations to protect the fund or seek to achieve its goal in light of market or economic conditions.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in various passively managed underlying funds that, as a group, hold a wide range of equity-type securities. The fund may also invest in various actively managed underlying funds. The fund is not designed to track an index or group of indexes. Equity-type securities include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. Each of the underlying funds has its own investment strategy that, for example, may focus on growth stocks, value stocks, or a combination of growth and income stocks. Underlying funds may invest in derivatives such as options on securities and futures contracts.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may also invest in derivatives such as credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, as well as in exchange-traded notes (ETNs). The fund may also purchase futures contracts for cash management purposes and to gain investment exposure pending investments.). The fund is also authorized to use various other investment strategies such as investing directly in fixed-income and equity securities, including U.S. government securities, mortgage-backed and asset-backed securities, closed-end funds, and partnerships. The fund may also short-sell securities.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The investment performance of each fund will reflect both its managers' allocation decisions with respect to the underlying funds and the investment decisions made by the underlying funds' managers.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Many factors affect performance, and fund shares will fluctuate in price, meaning you could lose money. The fund's investment strategy may not produce the intended results.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;During periods of heightened market volatility or reduced liquidity, governments, their agencies, or other regulatory bodies, both within the United States and abroad, may take steps to intervene. These actions, which could include legislative, regulatory, or economic initiatives, might have unforeseeable consequences and could adversely affect the fund's performance or otherwise constrain the fund's ability to achieve its investment objective.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in fixed-income securities than John Hancock Multi-Index Lifestyle Portfolios with greater target allocations to underlying funds that invest primarily in equity securities, fixed-income security risks are more prevalent in this fund than in other John Hancock Multi-Index Lifestyle Portfolios. In addition to fixed-income securities risk, the fund's other main risk factors are listed below in alphabetical order. &lt;i&gt;Before investing, be sure to read the additional descriptions of these risks beginning on page 32 of the prospectus.&lt;/i&gt;

               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions.&lt;/div&gt;

               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;

               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Investment company securities risk.&lt;/b&gt; A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Short sales risk.&lt;/b&gt; In a short sale, a fund pays interest on the borrowed security. The fund will lose money if the security price increases between the short sale and the replacement date.&lt;/div&gt;

U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support.

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;

               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;

Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;

               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;

               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;

               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;

               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The following information illustrates the variability of the fund's returns and provides some indication of the risks of investing in the fund by showing changes in the fund's performance from year to year and by showing how the fund's average annual returns compared with a broad-based market index. Past performance (before and after taxes) does not indicate future results. All figures assume dividend reinvestment. The fund's custom blended benchmark comprises 14% Russell 3000 Index/6% MSCI ACWI ex-USA Index/64% Bloomberg Barclays U.S. Aggregate Bond Index/16% ICE Bank of America Merrill Lynch U.S. High Yield Master II Index and shows how the fund's performance compares against the returns of similar investments. Performance information is updated daily, monthly, and quarterly and may be obtained at our website, jhinvestments.com, or by calling 800-225-5291 (Class A), Monday to Thursday, 8:00 A.M.&#8212;7:00 P.M., and Friday, 8:00 A.M.&#8212;6:00 P.M., Eastern time, or 888-972-8696 (Class I, Class R2, Class R4, and Class R5) between 8:30 A.M. and 5:00 P.M., Eastern time, on most business days.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Class 1 shares commenced operations on December 30, 2013.  Because Class A, Class I, Class R2, Class R4, and Class R5 shares of the fund had not commenced operations as of the date of this prospectus, the returns shown are those of Class 1 shares, except that they include any sales charges. Returns for Class A, Class I, Class R2, Class R4, and Class R5 shares would have been substantially similar to returns of Class 1 shares because each share class is invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.&lt;/div&gt;

Your actual after-tax returns may be different. After-tax returns are not relevant to shares held in an IRA, 401(k), or other tax-advantaged investment plan. After-tax returns for other share classes would vary.&lt;/div&gt;

Intermediaries may have different policies and procedures regarding the availability of front-end sales charge waivers or CDSC waivers (See Appendix 1 - Intermediary sales charge waivers, which includes information about specific sales charge waivers applicable to the intermediaries identified therein). More information about these and other discounts is available from your financial representative and on pages 54 to 56 of this prospectus under "Sales charge reductions and waivers" or pages 273 to 276 of the fund's Statement of Additional Information under "Sales Charges on Class A, Class B, and Class C Shares."&lt;/div&gt;

The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 16% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund operates as a fund of funds and, except as otherwise described below, normally invests approximately 20% of its assets in underlying funds that invest primarily in fixed-income securities and approximately 80% of its assets in underlying funds that invest primarily in equity securities. Underlying funds may be affiliated or unaffiliated and may include exchange-traded funds (ETFs).&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Variations in the target percentage allocation between underlying funds that invest primarily in equity securities and underlying funds that invest primarily in fixed-income securities are permitted up to 10%. There is no limit on the range of maturities and credit quality of securities in which the fund and underlying funds may invest. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from short to longer term. The fixed-income underlying funds collectively hold various types of debt instruments, such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging-market securities). The portfolio managers may exceed the normal percentage limitations to protect the fund or seek to achieve its goal in light of market or economic conditions.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in various passively managed underlying funds that, as a group, hold a wide range of equity-type securities. The fund may also invest in various actively managed underlying funds. The fund is not designed to track an index or group of indexes. Equity-type securities include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. Each of the underlying funds has its own investment strategy that, for example, may focus on growth stocks, value stocks, or a combination of growth and income stocks. Underlying funds may invest in derivatives such as options on securities and futures contracts.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may also invest in derivatives such as credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, as well as in exchange-traded notes (ETNs). The fund may also purchase futures contracts for cash management purposes and to gain investment exposure pending investments.). The fund is also authorized to use various other investment strategies such as investing directly in fixed-income and equity securities, including U.S. government securities, mortgage-backed and asset-backed securities, closed-end funds, and partnerships. The fund may also short-sell securities.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The investment performance of each fund will reflect both its managers' allocation decisions with respect to the underlying funds and the investment decisions made by the underlying funds' managers.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Many factors affect performance, and fund shares will fluctuate in price, meaning you could lose money. The fund's investment strategy may not produce the intended results.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;During periods of heightened market volatility or reduced liquidity, governments, their agencies, or other regulatory bodies, both within the United States and abroad, may take steps to intervene. These actions, which could include legislative, regulatory, or economic initiatives, might have unforeseeable consequences and could adversely affect the fund's performance or otherwise constrain the fund's ability to achieve its investment objective.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in equity securities than John Hancock Multi-Index Lifestyle Portfolios with greater target allocations to underlying funds that invest primarily in fixed-income securities, equity security risks are more prevalent in this fund than in other John Hancock Multi-Index Lifestyle Portfolios. In addition to equity securities risk, the fund's other main risk factors are listed below in alphabetical order. &lt;i&gt;Before investing, be sure to read the additional descriptions of these risks beginning on page 32 of the prospectus.&lt;/i&gt;            
            &lt;/div&gt;          
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                  &lt;i&gt;Principal risks of investing in the fund of funds &lt;/i&gt;              
               &lt;/b&gt;&lt;/div&gt;             
                     
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Investment company securities risk.&lt;/b&gt; A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Short sales risk.&lt;/b&gt; In a short sale, a fund pays interest on the borrowed security. The fund will lose money if the security price increases between the short sale and the replacement date.&lt;/div&gt;         
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                &lt;i&gt;  Principal risks of investing in the underlying funds   &lt;/i&gt;            
               &lt;/b&gt;&lt;/div&gt;             
                     
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;

Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations.

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment.

Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The following information illustrates the variability of the fund's returns and provides some indication of the risks of investing in the fund by showing changes in the fund's performance from year to year and by showing how the fund's average annual returns compared with a broad-based market index. Past performance (before and after taxes) does not indicate future results. All figures assume dividend reinvestment. The fund's custom blended benchmark comprises 56% Russell 3000 Index/24% MSCI ACWI ex-USA Index/4% ICE Bank of America Merrill Lynch U.S. High Yield Master II Index/16% Bloomberg Barclays U.S. Aggregate Bond Index and shows how the fund's performance compares against the returns of similar investments. Performance information is updated daily, monthly, and quarterly and may be obtained at our website, jhinvestments.com, or by calling 800-225-5291 (Class A), Monday to Thursday, 8:00 A.M.&#8212;7:00 P.M., and Friday, 8:00 A.M.&#8212;6:00 P.M., Eastern time, or 888-972-8696 (Class I, Class R2, Class R4, and Class R5) between 8:30 A.M. and 5:00 P.M., Eastern time, on most business days.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Class 1 shares commenced operations on December 30, 2013.  Because Class A, Class I, Class R2, Class R4, and Class R5 shares of the fund had not commenced operations as of the date of this prospectus, the returns shown are those of Class 1 shares, except that they include any sales charges. Returns for Class A, Class I, Class R2, Class R4, and Class R5 shares would have been substantially similar to returns of Class 1 shares because each share class is invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Please note that after-tax returns (shown for Class A shares only) reflect the highest individual federal marginal income-tax rate in effect as of the date provided and do not reflect any state or local taxes. Your actual after-tax returns may be different. After-tax returns are not relevant to shares held in an IRA, 401(k), or other tax-advantaged investment plan. After-tax returns for other share classes would vary.&lt;/div&gt;

The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 20% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund operates as a fund of funds and, except as otherwise described below, normally invests approximately 60% of its assets in underlying funds that invest primarily in fixed-income securities and approximately 40% in underlying funds that invest primarily in equity securities. Underlying funds may be affiliated or unaffiliated and may include exchange-traded funds (ETFs).&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Variations in the target percentage allocation between underlying funds that invest primarily in equity securities and underlying funds that invest primarily in fixed-income securities are permitted up to 10%. There is no limit on the range of maturities and credit quality of securities in which the fund and underlying funds may invest. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from short to longer term. The fixed-income underlying funds collectively hold various types of debt instruments, such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging-market securities). The portfolio managers may exceed the normal percentage limitations to protect the fund or seek to achieve its goal in light of market or economic conditions.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in various passively managed underlying funds that, as a group, hold a wide range of equity-type securities. The fund may also invest in various actively managed underlying funds. The fund is not designed to track an index or group of indexes. Equity-type securities include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. Each of the underlying funds has its own investment strategy that, for example, may focus on growth stocks, value stocks, or a combination of growth and income stocks. Underlying funds may invest in derivatives such as options on securities and futures contracts.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may also invest in derivatives such as credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, as well as in exchange-traded notes (ETNs). The fund may also purchase futures contracts for cash management purposes and to gain investment exposure pending investments.). The fund is also authorized to use various other investment strategies such as investing directly in fixed-income and equity securities, including U.S. government securities, mortgage-backed and asset-backed securities, closed-end funds, and partnerships. The fund may also short-sell securities.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The investment performance of each fund will reflect both its managers' allocation decisions with respect to the underlying funds and the investment decisions made by the underlying funds' managers.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Many factors affect performance, and fund shares will fluctuate in price, meaning you could lose money. The fund's investment strategy may not produce the intended results.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;During periods of heightened market volatility or reduced liquidity, governments, their agencies, or other regulatory bodies, both within the United States and abroad, may take steps to intervene. These actions, which could include legislative, regulatory, or economic initiatives, might have unforeseeable consequences and could adversely affect the fund's performance or otherwise constrain the fund's ability to achieve its investment objective.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in fixed-income securities than John Hancock Multi-Index Lifestyle Portfolios with greater target allocations to underlying funds that invest primarily in equity securities, fixed-income security risks are more prevalent in this fund than in other John Hancock Multi-Index Lifestyle Portfolios. In addition to fixed-income securities risk, the fund's other main risk factors are listed below in alphabetical order. &lt;i&gt;Before investing, be sure to read the additional descriptions of these risks beginning on page 32 of the prospectus.&lt;/i&gt;

               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;

               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions.&lt;/div&gt;

               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;

               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Investment company securities risk.&lt;/b&gt; A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Short sales risk.&lt;/b&gt; In a short sale, a fund pays interest on the borrowed security. The fund will lose money if the security price increases between the short sale and the replacement date.&lt;/div&gt;         
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
              &lt;i&gt;    Principal risks of investing in the underlying funds   &lt;/i&gt;            
               &lt;/b&gt;&lt;/div&gt;             
                     
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The following information illustrates the variability of the fund's returns and provides some indication of the risks of investing in the fund by showing changes in the fund's performance from year to year and by showing how the fund's average annual returns compared with a broad-based market index. Past performance (before and after taxes) does not indicate future results. All figures assume dividend reinvestment. The fund's custom blended benchmark comprises 28% Russell 3000 Index/12% MSCI ACWI ex-USA Index/48% Bloomberg Barclays U.S. Aggregate Bond Index/12% ICE Bank of America Merrill Lynch U.S. High Yield Master II Index and shows how the fund's performance compares against the returns of similar investments.

Returns for Class A, Class I, Class R2, Class R4, and Class R5 shares would have been substantially similar to returns of Class 1 shares because each share class is invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.&lt;/div&gt;

Your actual after-tax returns may be different. After-tax returns are not relevant to shares held in an IRA, 401(k), or other tax-advantaged investment plan.

Please see below a hypothetical example showing the expenses of a $10,000 investment for the time periods indicated and then assuming you sell all of your shares at the end of those periods. The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 15% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund operates as a fund of funds and, except as otherwise described below, normally invests approximately 100% of its assets in underlying funds that invest primarily in equity securities. Underlying funds may be affiliated or unaffiliated and may include exchange-traded funds (ETFs).&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Variations in the target percentage allocation between underlying funds that invest primarily in equity securities and underlying funds that invest primarily in fixed-income securities are permitted up to 10%. There is no limit on the range of maturities and credit quality of securities in which the fund and underlying funds may invest. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from short to longer term. The fixed-income underlying funds collectively hold various types of debt instruments, such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging-market securities). The portfolio managers may exceed the normal percentage limitations to protect the fund or seek to achieve its goal in light of market or economic conditions.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in various passively managed underlying funds that, as a group, hold a wide range of equity-type securities. The fund may also invest in various actively managed underlying funds. The fund is not designed to track an index or group of indexes. Equity-type securities include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. Each of the underlying funds has its own investment strategy that, for example, may focus on growth stocks, value stocks, or a combination of growth and income stocks. Underlying funds may invest in derivatives such as options on securities and futures contracts.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may also invest in derivatives such as credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, as well as in exchange-traded notes (ETNs). The fund may also purchase futures contracts for cash management purposes and to gain investment exposure pending investments.). The fund is also authorized to use various other investment strategies such as investing directly in fixed-income and equity securities, including U.S. government securities, mortgage-backed and asset-backed securities, closed-end funds, and partnerships. The fund may also short-sell securities.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The investment performance of each fund will reflect both its managers' allocation decisions with respect to the underlying funds and the investment decisions made by the underlying funds' managers.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Many factors affect performance, and fund shares will fluctuate in price, meaning you could lose money. The fund's investment strategy may not produce the intended results.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;During periods of heightened market volatility or reduced liquidity, governments, their agencies, or other regulatory bodies, both within the United States and abroad, may take steps to intervene. These actions, which could include legislative, regulatory, or economic initiatives, might have unforeseeable consequences and could adversely affect the fund's performance or otherwise constrain the fund's ability to achieve its investment objective.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in equity securities than John Hancock Multi-Index Lifestyle Portfolios with greater target allocations to underlying funds that invest primarily in fixed-income securities, equity security risks are more prevalent in this fund than in other John Hancock Multi-Index Lifestyle Portfolios. In addition to equity securities risk, the fund's other main risk factors are listed below in alphabetical order. &lt;i&gt;Before investing, be sure to read the additional descriptions of these risks beginning on page 27 of the prospectus.&lt;/i&gt;

               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;

               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;

               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions.&lt;/div&gt;

               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;

               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Investment company securities risk.&lt;/b&gt; A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Short sales risk.&lt;/b&gt; In a short sale, a fund pays interest on the borrowed security. The fund will lose money if the security price increases between the short sale and the replacement date.&lt;/div&gt;

               &lt;/b&gt;&lt;/div&gt;             
                     
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;

An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

Please see below a hypothetical example showing the expenses of a $10,000 investment for the time periods indicated and then assuming you sell all of your shares at the end of those periods. The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 17% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund operates as a fund of funds and, except as otherwise described below, normally invests approximately 40% of its assets in underlying funds that invest primarily in fixed-income securities and approximately 60% of its assets in underlying funds that invest primarily in equity securities. Underlying funds may be affiliated or unaffiliated and may include exchange-traded funds (ETFs).&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Variations in the target percentage allocation between underlying funds that invest primarily in equity securities and underlying funds that invest primarily in fixed-income securities are permitted up to 10%. There is no limit on the range of maturities and credit quality of securities in which the fund and underlying funds may invest. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from short to longer term. The fixed-income underlying funds collectively hold various types of debt instruments, such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging-market securities). The portfolio managers may exceed the normal percentage limitations to protect the fund or seek to achieve its goal in light of market or economic conditions.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in various passively managed underlying funds that, as a group, hold a wide range of equity-type securities. The fund may also invest in various actively managed underlying funds. The fund is not designed to track an index or group of indexes. Equity-type securities include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. Each of the underlying funds has its own investment strategy that, for example, may focus on growth stocks, value stocks, or a combination of growth and income stocks. Underlying funds may invest in derivatives such as options on securities and futures contracts.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may also invest in derivatives such as credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, as well as in exchange-traded notes (ETNs). The fund may also purchase futures contracts for cash management purposes and to gain investment exposure pending investments.). The fund is also authorized to use various other investment strategies such as investing directly in fixed-income and equity securities, including U.S. government securities, mortgage-backed and asset-backed securities, closed-end funds, and partnerships. The fund may also short-sell securities.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The investment performance of each fund will reflect both its managers' allocation decisions with respect to the underlying funds and the investment decisions made by the underlying funds' managers.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Many factors affect performance, and fund shares will fluctuate in price, meaning you could lose money. The fund's investment strategy may not produce the intended results.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;During periods of heightened market volatility or reduced liquidity, governments, their agencies, or other regulatory bodies, both within the United States and abroad, may take steps to intervene. These actions, which could include legislative, regulatory, or economic initiatives, might have unforeseeable consequences and could adversely affect the fund's performance or otherwise constrain the fund's ability to achieve its investment objective.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in equity securities than John Hancock Multi-Index Lifestyle Portfolios with greater target allocations to underlying funds that invest primarily in fixed-income securities, equity security risks are more prevalent in this fund than in other John Hancock Multi-Index Lifestyle Portfolios. In addition to equity securities risk, the fund's other main risk factors are listed below in alphabetical order. &lt;i&gt;Before investing, be sure to read the additional descriptions of these risks beginning on page 27 of the prospectus.&lt;/i&gt;            
            &lt;/div&gt;

               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;

               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions.&lt;/div&gt;

               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Investment company securities risk.&lt;/b&gt; A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Short sales risk.&lt;/b&gt; In a short sale, a fund pays interest on the borrowed security. The fund will lose money if the security price increases between the short sale and the replacement date.&lt;/div&gt;

               &lt;i&gt;   Principal risks of investing in the underlying funds   &lt;/i&gt;            
               &lt;/b&gt;&lt;/div&gt;             
                     
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

Please see below a hypothetical example showing the expenses of a $10,000 investment for the time periods indicated and then assuming you sell all of your shares at the end of those periods. The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 24% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund operates as a fund of funds and, except as otherwise described below, normally invests approximately 80% of its assets in underlying funds that invest primarily in fixed-income securities and approximately 20% in underlying funds that invest primarily in equity securities. Underlying funds may be affiliated or unaffiliated and may include exchange-traded funds (ETFs).&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Variations in the target percentage allocation between underlying funds that invest primarily in equity securities and underlying funds that invest primarily in fixed-income securities are permitted up to 10%. There is no limit on the range of maturities and credit quality of securities in which the fund and underlying funds may invest. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from short to longer term. The fixed-income underlying funds collectively hold various types of debt instruments, such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging-market securities). The portfolio managers may exceed the normal percentage limitations to protect the fund or seek to achieve its goal in light of market or economic conditions.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in various passively managed underlying funds that, as a group, hold a wide range of equity-type securities. The fund may also invest in various actively managed underlying funds. The fund is not designed to track an index or group of indexes. Equity-type securities include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. Each of the underlying funds has its own investment strategy that, for example, may focus on growth stocks, value stocks, or a combination of growth and income stocks. Underlying funds may invest in derivatives such as options on securities and futures contracts.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may also invest in derivatives such as credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, as well as in exchange-traded notes (ETNs). The fund may also purchase futures contracts for cash management purposes and to gain investment exposure pending investments.). The fund is also authorized to use various other investment strategies such as investing directly in fixed-income and equity securities, including U.S. government securities, mortgage-backed and asset-backed securities, closed-end funds, and partnerships. The fund may also short-sell securities.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The investment performance of each fund will reflect both its managers' allocation decisions with respect to the underlying funds and the investment decisions made by the underlying funds' managers.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Many factors affect performance, and fund shares will fluctuate in price, meaning you could lose money. The fund's investment strategy may not produce the intended results.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;During periods of heightened market volatility or reduced liquidity, governments, their agencies, or other regulatory bodies, both within the United States and abroad, may take steps to intervene. These actions, which could include legislative, regulatory, or economic initiatives, might have unforeseeable consequences and could adversely affect the fund's performance or otherwise constrain the fund's ability to achieve its investment objective.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in fixed-income securities than John Hancock Multi-Index Lifestyle Portfolios with greater target allocations to underlying funds that invest primarily in equity securities, fixed-income security risks are more prevalent in this fund than in other John Hancock Multi-Index Lifestyle Portfolios. In addition to fixed-income securities risk, the fund's other main risk factors are listed below in alphabetical order. &lt;i&gt;Before investing, be sure to read the additional descriptions of these risks beginning on page 27 of the prospectus.&lt;/i&gt;            
            &lt;/div&gt;

               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;

               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;

               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions.&lt;/div&gt;

               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;

               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Investment company securities risk.&lt;/b&gt; A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Short sales risk.&lt;/b&gt; In a short sale, a fund pays interest on the borrowed security. The fund will lose money if the security price increases between the short sale and the replacement date.&lt;/div&gt;

               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

Please see below a hypothetical example showing the expenses of a $10,000 investment for the time periods indicated and then assuming you sell all of your shares at the end of those periods. The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 16% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund operates as a fund of funds and, except as otherwise described below, normally invests approximately 20% of its assets in underlying funds that invest primarily in fixed-income securities and approximately 80% of its assets in underlying funds that invest primarily in equity securities. Underlying funds may be affiliated or unaffiliated and may include exchange-traded funds (ETFs).&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Variations in the target percentage allocation between underlying funds that invest primarily in equity securities and underlying funds that invest primarily in fixed-income securities are permitted up to 10%. There is no limit on the range of maturities and credit quality of securities in which the fund and underlying funds may invest. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from short to longer term. The fixed-income underlying funds collectively hold various types of debt instruments, such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging-market securities). The portfolio managers may exceed the normal percentage limitations to protect the fund or seek to achieve its goal in light of market or economic conditions.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in various passively managed underlying funds that, as a group, hold a wide range of equity-type securities. The fund may also invest in various actively managed underlying funds. The fund is not designed to track an index or group of indexes. Equity-type securities include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. Each of the underlying funds has its own investment strategy that, for example, may focus on growth stocks, value stocks, or a combination of growth and income stocks. Underlying funds may invest in derivatives such as options on securities and futures contracts.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may also invest in derivatives such as credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, as well as in exchange-traded notes (ETNs). The fund may also purchase futures contracts for cash management purposes and to gain investment exposure pending investments.). The fund is also authorized to use various other investment strategies such as investing directly in fixed-income and equity securities, including U.S. government securities, mortgage-backed and asset-backed securities, closed-end funds, and partnerships. The fund may also short-sell securities.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The investment performance of each fund will reflect both its managers' allocation decisions with respect to the underlying funds and the investment decisions made by the underlying funds' managers.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Many factors affect performance, and fund shares will fluctuate in price, meaning you could lose money. The fund's investment strategy may not produce the intended results.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;During periods of heightened market volatility or reduced liquidity, governments, their agencies, or other regulatory bodies, both within the United States and abroad, may take steps to intervene. These actions, which could include legislative, regulatory, or economic initiatives, might have unforeseeable consequences and could adversely affect the fund's performance or otherwise constrain the fund's ability to achieve its investment objective.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in equity securities than John Hancock Multi-Index Lifestyle Portfolios with greater target allocations to underlying funds that invest primarily in fixed-income securities, equity security risks are more prevalent in this fund than in other John Hancock Multi-Index Lifestyle Portfolios. In addition to equity securities risk, the fund's other main risk factors are listed below in alphabetical order. &lt;i&gt;Before investing, be sure to read the additional descriptions of these risks beginning on page 27 of the prospectus.&lt;/i&gt;

               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;

               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;

               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions.&lt;/div&gt;

               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;

               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Investment company securities risk.&lt;/b&gt; A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Short sales risk.&lt;/b&gt; In a short sale, a fund pays interest on the borrowed security. The fund will lose money if the security price increases between the short sale and the replacement date.&lt;/div&gt;

              &lt;i&gt;    Principal risks of investing in the underlying funds   &lt;/i&gt;            
               &lt;/b&gt;&lt;/div&gt;             
                     
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;

Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;This example is intended to help you compare the cost of investing in the fund with the cost of investing in other mutual funds. Please see below a hypothetical example showing the expenses of a $10,000 investment for the time periods indicated and then assuming you sell all of your shares at the end of those periods. The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 20% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund operates as a fund of funds and, except as otherwise described below, normally invests approximately 60% of its assets in underlying funds that invest primarily in fixed-income securities and approximately 40% in underlying funds that invest primarily in equity securities. Underlying funds may be affiliated or unaffiliated and may include exchange-traded funds (ETFs).&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Variations in the target percentage allocation between underlying funds that invest primarily in equity securities and underlying funds that invest primarily in fixed-income securities are permitted up to 10%. There is no limit on the range of maturities and credit quality of securities in which the fund and underlying funds may invest. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from short to longer term. The fixed-income underlying funds collectively hold various types of debt instruments, such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging-market securities). The portfolio managers may exceed the normal percentage limitations to protect the fund or seek to achieve its goal in light of market or economic conditions.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in various passively managed underlying funds that, as a group, hold a wide range of equity-type securities. The fund may also invest in various actively managed underlying funds. The fund is not designed to track an index or group of indexes. Equity-type securities include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. Each of the underlying funds has its own investment strategy that, for example, may focus on growth stocks, value stocks, or a combination of growth and income stocks. Underlying funds may invest in derivatives such as options on securities and futures contracts.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may also invest in derivatives such as credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, as well as in exchange-traded notes (ETNs). The fund may also purchase futures contracts for cash management purposes and to gain investment exposure pending investments.). The fund is also authorized to use various other investment strategies such as investing directly in fixed-income and equity securities, including U.S. government securities, mortgage-backed and asset-backed securities, closed-end funds, and partnerships. The fund may also short-sell securities.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The investment performance of each fund will reflect both its managers' allocation decisions with respect to the underlying funds and the investment decisions made by the underlying funds' managers.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Many factors affect performance, and fund shares will fluctuate in price, meaning you could lose money. The fund's investment strategy may not produce the intended results.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;During periods of heightened market volatility or reduced liquidity, governments, their agencies, or other regulatory bodies, both within the United States and abroad, may take steps to intervene. These actions, which could include legislative, regulatory, or economic initiatives, might have unforeseeable consequences and could adversely affect the fund's performance or otherwise constrain the fund's ability to achieve its investment objective.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in fixed-income securities than John Hancock Multi-Index Lifestyle Portfolios with greater target allocations to underlying funds that invest primarily in equity securities, fixed-income security risks are more prevalent in this fund than in other John Hancock Multi-Index Lifestyle Portfolios. In addition to fixed-income securities risk, the fund's other main risk factors are listed below in alphabetical order. &lt;i&gt;Before investing, be sure to read the additional descriptions of these risks beginning on page 27 of the prospectus.&lt;/i&gt;            
            &lt;/div&gt;

               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions.&lt;/div&gt;

               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Investment company securities risk.&lt;/b&gt; A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Short sales risk.&lt;/b&gt; In a short sale, a fund pays interest on the borrowed security. The fund will lose money if the security price increases between the short sale and the replacement date.&lt;/div&gt;

               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;

               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;

               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;

               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;

               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;

               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;

               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;This example is intended to help you compare the cost of investing in the fund with the cost of investing in other mutual funds. Please see below a hypothetical example showing the expenses of a $10,000 investment for the time periods indicated and then assuming you sell all of your shares at the end of those periods. The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 49% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests substantially all of its assets in underlying funds using an asset allocation strategy designed for investors expected to retire around the year 2010.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The portfolio managers of the fund allocate assets among the underlying funds according to an asset allocation strategy that becomes increasingly conservative over time. John Hancock Multi-Index 2010 Lifetime Portfolio has a target asset allocation of 38.75% of its assets in underlying funds that invest primarily in equity securities. The fund will have a greater exposure to underlying funds that invest primarily in fixed-income securities than will a John Hancock Multi-Index Lifetime Portfolio with a more distant target date. To reduce investment risk and volatility as retirement approaches and in the postretirement years, the asset allocation strategy will change over time according to a predetermined "glide path" shown in the following chart. The fund may be a primary source of income for its shareholders after retirement.&lt;/div&gt;         
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                  GLIDE PATH CHART               
               &lt;/b&gt;&lt;/div&gt;   
&lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;/div&gt;           
                  &lt;img alt="glidepath chart" src="glidepath.jpg"&gt;&lt;/img&gt;     
                  
                   

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The allocations reflected in the glide path are referred to as target allocations because they do not reflect active decisions made by the portfolio managers to produce an overweight or an underweight position in a particular asset class. The fund has a target allocation to underlying funds that invest in the broad asset classes of equity and fixed-income securities, but may also allocate its assets to underlying funds that invest outside these asset classes to protect the fund or help it achieve its objective. For example, the fund may also allocate its assets to underlying funds that invest in alternative and specialty asset classes. The managers may change the target allocation without shareholder approval if they believe that such change would benefit the fund and its shareholders. Under normal circumstances, any deviation from the target allocation is not expected to be greater than plus or minus 10%.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Within the prescribed percentage allocation, the managers select the percentage level to be maintained in specific underlying funds. New investments made by the fund may be directed to particular underlying funds in an effort to maintain the desired target allocations. There is no guarantee that the portfolio managers will correctly predict the market or economic conditions and, as with other mutual fund investments, you could lose money even if the fund is at or close to its designated retirement year or in its postretirement stage.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is designed for investors who may remain invested in the fund through their retirement years. The fund will continue to be managed according to an allocation strategy that becomes increasingly conservative over time until approximately twenty years after retirement, at which time the fund expects to maintain a static allocation of approximately 25% of its assets in equity underlying funds.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in underlying funds that invest in a broad range of equity, fixed-income, and alternative/specialty securities and asset classes, including, but not limited to, U.S. and foreign securities, including emerging-market securities, commodities, asset-backed securities, small-cap securities, and below-investment-grade securities (i.e., junk bonds). The underlying funds may also use derivatives, such as swaps, foreign currency forwards, futures, and options, in each case for the purposes of reducing risk, obtaining efficient market exposure and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund will invest in various passively managed underlying funds that as a group hold a wide range of equity-type securities in their portfolios, including convertible securities. The fund may also invest in various actively managed funds. The fund is not designed to track an index or group of indexes. Equity-type securities include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. Certain equity underlying funds may invest in initial public offerings (IPOs). Each of the equity underlying funds has its own investment strategy that, for example, may focus on growth stocks or value stocks, or may employ a strategy combining growth and income stocks, and/or may invest in derivatives such as credit default swaps, foreign currency forwards, interest rate swaps, options on securities, and futures contracts. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from shorter to longer term. The fixed-income underlying funds collectively hold various types of debt instruments such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging market securities). Certain underlying funds may invest in illiquid securities, and certain underlying funds may be non-diversified.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest directly in exchange-traded funds (ETFs), exchange-traded notes (ETNs), the securities of other investment companies, U.S. government securities, and other types of investments such as derivatives, including credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, in each case for the purposes of reducing risk, obtaining efficient market exposure, and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;To the extent permitted by law, the Board of Trustees of the fund may, in its discretion, determine to combine the fund with another fund without shareholder approval if the target allocation of the fund matches the target allocation of the other fund, although there is no assurance that the Board of Trustees will so determine at any point. The fund bears its own expenses and, in addition, indirectly bears its proportionate share of the expenses of the underlying funds in which it invests. The fund's performance reflects both the managers' allocation decisions and the performance of the underlying funds.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Many factors affect performance, and fund shares will fluctuate in price, meaning you could lose money. The fund's investment strategy may not produce the intended results.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;During periods of heightened market volatility or reduced liquidity, governments, their agencies, or other regulatory bodies, both within the United States and abroad, may take steps to intervene. These actions, which could include legislative, regulatory, or economic initiatives, might have unforeseeable consequences and could adversely affect the fund's performance or otherwise constrain the fund's ability to achieve its investment objective.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in fixed-income securities than John Hancock Multi-Index Lifetime Portfolios with target dates that are more distant, fixed-income securities risks are more prevalent in this fund than in these other target-date funds. In addition to fixed-income securities risk, the fund's other main risk factors are listed below in alphabetical order. &lt;i&gt;Before investing, be sure to read the additional descriptions of these risks beginning on page 68 of the prospectus.&lt;/i&gt;

               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk based on the nature of their support.&lt;/div&gt;

               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;

               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;

               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;

               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;

               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;

               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;

               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The following information illustrates the variability of the fund's returns and provides some indication of the risks of investing in the fund by showing changes in the fund's performance from year to year and by showing how the fund's average annual returns compared with a broad-based market index. Past performance (before and after taxes) does not indicate future results. All figures assume dividend reinvestment. Performance information is updated daily, monthly, and quarterly and may be obtained at our website, jhinvestments.com, or by calling 888-972-8696 between 8:30 A.M. and 5:00 P.M., Eastern time, on most business days.&lt;/div&gt;

The information shows how the fund's performance compares with the returns of an index of funds with similar investment objectives. From December 1, 2016 to November 30, 2017, the Custom Benchmark consisted of the following indices and approximate weightings: 28.88% Russell 3000 Index, 12.37% MSCI ACWI ex-USA Index, 47.00% Bloomberg Barclays U.S. Aggregate Bond Index, and 11.75% ICE Bank of America Merrill Lynch U.S. High Yield Master II Index. The weightings of the indices in the Custom Benchmark are adjusted annually to reflect changes in the fund's target asset allocation in accordance with the annual roll-down of the glide path described above and differed in periods prior to December 1, 2016.&lt;/div&gt;

Because Class I and Class R5 shares of the fund had not commenced operations as of the date of this prospectus, the returns shown are those of Class 1 shares. Returns for Class I and Class R5 shares would have been substantially similar to returns of Class 1 shares because each share class is invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.&lt;/div&gt;

Your actual after-tax returns may be different. After-tax returns are not relevant to shares held in an IRA, 401(k), or other tax-advantaged investment plan.

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 28% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests substantially all of its assets in underlying funds using an asset allocation strategy designed for investors expected to retire around the year 2015.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The portfolio managers of the fund allocate assets among the underlying funds according to an asset allocation strategy that becomes increasingly conservative over time. John Hancock Multi-Index 2015 Lifetime Portfolio has a target asset allocation of 45% of its assets in underlying funds that invest primarily in equity securities. The fund will have a greater exposure to underlying funds that invest primarily in fixed-income securities than will a Multi-Index Lifetime Portfolio with a more distant target date. To reduce investment risk and volatility as retirement approaches and in the postretirement years, the asset allocation strategy will change over time according to a predetermined "glide path" shown in the following chart. The fund may be a primary source of income for its shareholders after retirement.&lt;/div&gt;         
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                  GLIDE PATH CHART               
               &lt;/b&gt;&lt;/div&gt;             
                     &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;/div&gt;
                 &lt;img alt="glidepath chart" src="glidepath.jpg"&gt;&lt;/img&gt;    
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The allocations reflected in the glide path are referred to as target allocations because they do not reflect active decisions made by the portfolio managers to produce an overweight or an underweight position in a particular asset class. The fund has a target allocation to underlying funds that invest in the broad asset classes of equity and fixed-income securities, but may also allocate its assets to underlying funds that invest outside these asset classes to protect the fund or help it achieve its objective. For example, the fund may also allocate its assets to underlying funds that invest in alternative and specialty asset classes. The managers may change the target allocation without shareholder approval if they believe that such change would benefit the fund and its shareholders. Under normal circumstances, any deviation from the target allocation is not expected to be greater than plus or minus 10%.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Within the prescribed percentage allocation, the managers select the percentage level to be maintained in specific underlying funds. New investments made by the fund may be directed to particular underlying funds in an effort to maintain the desired target allocations. There is no guarantee that the portfolio managers will correctly predict the market or economic conditions and, as with other mutual fund investments, you could lose money even if the fund is at or close to its designated retirement year or in its postretirement stage.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is designed for investors who may remain invested in the fund through their retirement years. The fund will continue to be managed according to an allocation strategy that becomes increasingly conservative over time until approximately twenty years after retirement, at which time the fund expects to maintain a static allocation of approximately 25% of its assets in equity underlying funds.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in underlying funds that invest in a broad range of equity, fixed-income, and alternative/specialty securities and asset classes, including, but not limited to, U.S. and foreign securities, including emerging-market securities, commodities, asset-backed securities, small-cap securities, and below-investment-grade securities (i.e., junk bonds). The underlying funds may also use derivatives, such as swaps, foreign currency forwards, futures, and options, in each case for the purposes of reducing risk, obtaining efficient market exposure and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund will invest in various passively managed underlying funds that as a group hold a wide range of equity-type securities in their portfolios, including convertible securities. The fund may also invest in various actively managed funds. The fund is not designed to track an index or group of indexes. Equity-type securities include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. Certain equity underlying funds may invest in initial public offerings (IPOs). Each of the equity underlying funds has its own investment strategy that, for example, may focus on growth stocks or value stocks, or may employ a strategy combining growth and income stocks, and/or may invest in derivatives such as credit default swaps, foreign currency forwards, interest rate swaps, options on securities, and futures contracts. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from shorter to longer term. The fixed-income underlying funds collectively hold various types of debt instruments such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging market securities). Certain underlying funds may invest in illiquid securities, and certain underlying funds may be non-diversified.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest directly in exchange-traded funds (ETFs), exchange-traded notes (ETNs), the securities of other investment companies, U.S. government securities, and other types of investments such as derivatives, including credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, in each case for the purposes of reducing risk, obtaining efficient market exposure, and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;To the extent permitted by law, the Board of Trustees of the fund may, in its discretion, determine to combine the fund with another fund without shareholder approval if the target allocation of the fund matches the target allocation of the other fund, although there is no assurance that the Board of Trustees will so determine at any point. The fund bears its own expenses and, in addition, indirectly bears its proportionate share of the expenses of the underlying funds in which it invests. The fund's performance reflects both the managers' allocation decisions and the performance of the underlying funds.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Many factors affect performance, and fund shares will fluctuate in price, meaning you could lose money. The fund's investment strategy may not produce the intended results.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;During periods of heightened market volatility or reduced liquidity, governments, their agencies, or other regulatory bodies, both within the United States and abroad, may take steps to intervene. These actions, which could include legislative, regulatory, or economic initiatives, might have unforeseeable consequences and could adversely affect the fund's performance or otherwise constrain the fund's ability to achieve its investment objective.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in fixed-income securities than John Hancock Multi-Index Lifetime Portfolios with target dates that are more distant, fixed-income securities risks are more prevalent in this fund than in these other target-date funds. In addition to fixed-income securities risk, the fund's other main risk factors are listed below in alphabetical order. &lt;i&gt;Before investing, be sure to read the additional descriptions of these risks beginning on page 68 of the prospectus.&lt;/i&gt;

               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk based on the nature of their support.&lt;/div&gt;

               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;

               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;

               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;

               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Investment company securities risk.&lt;/b&gt; A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;

               &lt;b&gt;Lifecycle risk.&lt;/b&gt; Managers might not correctly predict market or economic conditions, and you could lose money even close to, during, or after the fund's designated retirement year.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Target allocation risk.&lt;/b&gt; The fund's risk profile will change due to reallocation or rebalancing of portfolio assets as the fund approaches its target date.&lt;/div&gt;

                &lt;i&gt;  Principal risks of investing in the underlying funds  &lt;/i&gt;             
               &lt;/b&gt;&lt;/div&gt;             
                     
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

The information shows how the fund's performance compares with the returns of an index of funds with similar investment objectives. From December 1, 2016 to November 30, 2017, the Custom Benchmark consisted of the following indices and approximate weightings: 33.25% Russell 3000 Index, 14.25% MSCI ACWI ex-USA Index, 42.00% Bloomberg Barclays U.S. Aggregate Bond Index, and 10.50% ICE Bank of America Merrill Lynch U.S. High Yield Master II Index. The weightings of the indices in the Custom Benchmark are adjusted annually to reflect changes in the fund's target asset allocation in accordance with the annual roll-down of the glide path described above and differed in periods prior to December 1, 2016.&lt;/div&gt;

Because Class I and Class R5 shares of the fund had not commenced operations as of the date of this prospectus, the returns shown are those of Class 1 shares. Returns for Class I and Class R5 shares would have been substantially similar to returns of Class 1 shares because each share class is invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.&lt;/div&gt;

The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 30% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests substantially all of its assets in underlying funds using an asset allocation strategy designed for investors expected to retire around the year 2020.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The portfolio managers of the fund allocate assets among the underlying funds according to an asset allocation strategy that becomes increasingly conservative over time. John Hancock Multi-Index 2020 Lifetime Portfolio has a target asset allocation of 54% of its assets in underlying funds that invest primarily in equity securities. The fund will have a greater exposure to underlying funds that invest primarily in equity securities than will a John Hancock Multi-Index Lifetime Portfolio with a closer target date. To reduce investment risk and volatility as retirement approaches and in the postretirement years, the asset allocation strategy will change over time according to a predetermined "glide path" shown in the following chart. The fund may be a primary source of income for its shareholders after retirement.&lt;/div&gt;         
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                  GLIDE PATH CHART               
               &lt;/b&gt;&lt;/div&gt; 
&lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;/div&gt;            
                    &lt;img alt="glidepath chart" src="glidepath.jpg"&gt;&lt;/img&gt;    
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The allocations reflected in the glide path are referred to as target allocations because they do not reflect active decisions made by the portfolio managers to produce an overweight or an underweight position in a particular asset class. The fund has a target allocation to underlying funds that invest in the broad asset classes of equity and fixed-income securities, but may also allocate its assets to underlying funds that invest outside these asset classes to protect the fund or help it achieve its objective. For example, the fund may also allocate its assets to underlying funds that invest in alternative and specialty asset classes. The managers may change the target allocation without shareholder approval if they believe that such change would benefit the fund and its shareholders. Under normal circumstances, any deviation from the target allocation is not expected to be greater than plus or minus 10%.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Within the prescribed percentage allocation, the managers select the percentage level to be maintained in specific underlying funds. New investments made by the fund may be directed to particular underlying funds in an effort to maintain the desired target allocations. There is no guarantee that the portfolio managers will correctly predict the market or economic conditions and, as with other mutual fund investments, you could lose money even if the fund is at or close to its designated retirement year or in its postretirement stage.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is designed for investors who may remain invested in the fund through their retirement years. The fund will continue to be managed according to an allocation strategy that becomes increasingly conservative over time until approximately twenty years after retirement, at which time the fund expects to maintain a static allocation of approximately 25% of its assets in equity underlying funds.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in underlying funds that invest in a broad range of equity, fixed-income, and alternative/specialty securities and asset classes, including, but not limited to, U.S. and foreign securities, including emerging-market securities, commodities, asset-backed securities, small-cap securities, and below-investment-grade securities (i.e., junk bonds). The underlying funds may also use derivatives, such as swaps, foreign currency forwards, futures, and options, in each case for the purposes of reducing risk, obtaining efficient market exposure and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund will invest in various passively managed underlying funds that as a group hold a wide range of equity-type securities in their portfolios, including convertible securities. The fund may also invest in various actively managed funds. The fund is not designed to track an index or group of indexes. Equity-type securities include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. Certain equity underlying funds may invest in initial public offerings (IPOs). Each of the equity underlying funds has its own investment strategy that, for example, may focus on growth stocks or value stocks, or may employ a strategy combining growth and income stocks, and/or may invest in derivatives such as credit default swaps, foreign currency forwards, interest rate swaps, options on securities, and futures contracts. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from shorter to longer term. The fixed-income underlying funds collectively hold various types of debt instruments such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging market securities). Certain underlying funds may invest in illiquid securities, and certain underlying funds may be non-diversified.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest directly in exchange-traded funds (ETFs), exchange-traded notes (ETNs), the securities of other investment companies, U.S. government securities, and other types of investments such as derivatives, including credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, in each case for the purposes of reducing risk, obtaining efficient market exposure, and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;To the extent permitted by law, the Board of Trustees of the fund may, in its discretion, determine to combine the fund with another fund without shareholder approval if the target allocation of the fund matches the target allocation of the other fund, although there is no assurance that the Board of Trustees will so determine at any point. The fund bears its own expenses and, in addition, indirectly bears its proportionate share of the expenses of the underlying funds in which it invests. The fund's performance reflects both the managers' allocation decisions and the performance of the underlying funds.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Many factors affect performance, and fund shares will fluctuate in price, meaning you could lose money. The fund's investment strategy may not produce the intended results.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;During periods of heightened market volatility or reduced liquidity, governments, their agencies, or other regulatory bodies, both within the United States and abroad, may take steps to intervene. These actions, which could include legislative, regulatory, or economic initiatives, might have unforeseeable consequences and could adversely affect the fund's performance or otherwise constrain the fund's ability to achieve its investment objective.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in equity securities than John Hancock Multi-Index Lifetime Portfolios with closer target dates, equity security risks are more prevalent in this fund than in these other target-date funds. In addition to equity securities risk, the fund's other main risk factors are listed below in alphabetical order. &lt;i&gt;Before investing, be sure to read the additional descriptions of these risks beginning on page 68 of the prospectus.&lt;/i&gt;            
            &lt;/div&gt;

               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk based on the nature of their support.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;

               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;

               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;

               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;

               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;

               &lt;b&gt;Lifecycle risk.&lt;/b&gt; Managers might not correctly predict market or economic conditions, and you could lose money even close to, during, or after the fund's designated retirement year.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Target allocation risk.&lt;/b&gt; The fund's risk profile will change due to reallocation or rebalancing of portfolio assets as the fund approaches its target date.&lt;/div&gt;

                  &lt;i&gt;Principal risks of investing in the underlying funds  &lt;/i&gt;

               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The following information illustrates the variability of the fund's returns and provides some indication of the risks of investing in the fund by showing changes in the fund's performance from year to year and by showing how the fund's average annual returns compared with a broad-based market index. Past performance (before and after taxes) does not indicate future results. All figures assume dividend reinvestment. Performance information is updated daily, monthly, and quarterly and may be obtained at our website, jhinvestments.com, or by calling 888-972-8696 between 8:30 A.M. and 5:00 P.M., Eastern time, on most business days.&lt;/div&gt;

The information shows how the fund's performance compares with the returns of an index of funds with similar investment objectives. From December 1, 2016 to November 30, 2017, the Custom Benchmark consisted of the following indices and approximate weightings: 40.60% Russell 3000 Index, 17.40% MSCI ACWI ex-USA Index, 33.60% Bloomberg Barclays U.S. Aggregate Bond Index, and 8.40% ICE Bank of America Merrill Lynch U.S. High Yield Master II Index. The weightings of the indices in the Custom Benchmark are adjusted annually to reflect changes in the fund's target asset allocation in accordance with the annual roll-down of the glide path described above and differed in periods prior to December 1, 2016.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Class 1 shares commenced operations on November 7, 2013. Because Class I and Class R5 shares of the fund had not commenced operations as of the date of this prospectus, the returns shown are those of Class 1 shares. Returns for Class I and Class R5 shares would have been substantially similar to returns of Class 1 shares because each share class is invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Please note that after-tax returns (shown for Class I shares only) reflect the highest individual federal marginal income-tax rate in effect as of the date provided and do not reflect any state or local taxes. Your actual after-tax returns may be different. After-tax returns are not relevant to shares held in an IRA, 401(k), or other tax-advantaged investment plan. After-tax returns for other share classes would vary.&lt;/div&gt;

The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 23% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests substantially all of its assets in underlying funds using an asset allocation strategy designed for investors expected to retire around the year 2025.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The portfolio managers of the fund allocate assets among the underlying funds according to an asset allocation strategy that becomes increasingly conservative over time. John Hancock Multi-Index 2025 Lifetime Portfolio has a target asset allocation of 65% of its assets in underlying funds that invest primarily in equity securities. The fund will have a greater exposure to underlying funds that invest primarily in equity securities than will a John Hancock Multi-Index Lifetime Portfolio with a closer target date. To reduce investment risk and volatility as retirement approaches and in the postretirement years, the asset allocation strategy will change over time according to a predetermined "glide path" shown in the following chart. The fund may be a primary source of income for its shareholders after retirement.&lt;/div&gt;         
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                  GLIDE PATH CHART               
               &lt;/b&gt;&lt;/div&gt;             
                     &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;/div&gt;
                  &lt;img alt="glidepath chart" src="glidepath.jpg"&gt;&lt;/img&gt;   
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The allocations reflected in the glide path are referred to as target allocations because they do not reflect active decisions made by the portfolio managers to produce an overweight or an underweight position in a particular asset class. The fund has a target allocation to underlying funds that invest in the broad asset classes of equity and fixed-income securities, but may also allocate its assets to underlying funds that invest outside these asset classes to protect the fund or help it achieve its objective. For example, the fund may also allocate its assets to underlying funds that invest in alternative and specialty asset classes. The managers may change the target allocation without shareholder approval if they believe that such change would benefit the fund and its shareholders. Under normal circumstances, any deviation from the target allocation is not expected to be greater than plus or minus 10%.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Within the prescribed percentage allocation, the managers select the percentage level to be maintained in specific underlying funds. New investments made by the fund may be directed to particular underlying funds in an effort to maintain the desired target allocations. There is no guarantee that the portfolio managers will correctly predict the market or economic conditions and, as with other mutual fund investments, you could lose money even if the fund is at or close to its designated retirement year or in its postretirement stage.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is designed for investors who may remain invested in the fund through their retirement years. The fund will continue to be managed according to an allocation strategy that becomes increasingly conservative over time until approximately twenty years after retirement, at which time the fund expects to maintain a static allocation of approximately 25% of its assets in equity underlying funds.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in underlying funds that invest in a broad range of equity, fixed-income, and alternative/specialty securities and asset classes, including, but not limited to, U.S. and foreign securities, including emerging-market securities, commodities, asset-backed securities, small-cap securities, and below-investment-grade securities (i.e., junk bonds). The underlying funds may also use derivatives, such as swaps, foreign currency forwards, futures, and options, in each case for the purposes of reducing risk, obtaining efficient market exposure and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund will invest in various passively managed underlying funds that as a group hold a wide range of equity-type securities in their portfolios, including convertible securities. The fund may also invest in various actively managed funds. The fund is not designed to track an index or group of indexes. Equity-type securities include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. Certain equity underlying funds may invest in initial public offerings (IPOs). Each of the equity underlying funds has its own investment strategy that, for example, may focus on growth stocks or value stocks, or may employ a strategy combining growth and income stocks, and/or may invest in derivatives such as credit default swaps, foreign currency forwards, interest rate swaps, options on securities, and futures contracts. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from shorter to longer term. The fixed-income underlying funds collectively hold various types of debt instruments such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging market securities). Certain underlying funds may invest in illiquid securities, and certain underlying funds may be non-diversified.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest directly in exchange-traded funds (ETFs), exchange-traded notes (ETNs), the securities of other investment companies, U.S. government securities, and other types of investments such as derivatives, including credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, in each case for the purposes of reducing risk, obtaining efficient market exposure, and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;To the extent permitted by law, the Board of Trustees of the fund may, in its discretion, determine to combine the fund with another fund without shareholder approval if the target allocation of the fund matches the target allocation of the other fund, although there is no assurance that the Board of Trustees will so determine at any point. The fund bears its own expenses and, in addition, indirectly bears its proportionate share of the expenses of the underlying funds in which it invests. The fund's performance reflects both the managers' allocation decisions and the performance of the underlying funds.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Many factors affect performance, and fund shares will fluctuate in price, meaning you could lose money. The fund's investment strategy may not produce the intended results.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;During periods of heightened market volatility or reduced liquidity, governments, their agencies, or other regulatory bodies, both within the United States and abroad, may take steps to intervene. These actions, which could include legislative, regulatory, or economic initiatives, might have unforeseeable consequences and could adversely affect the fund's performance or otherwise constrain the fund's ability to achieve its investment objective.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in equity securities than John Hancock Multi-Index Lifetime Portfolios with closer target dates, equity security risks are more prevalent in this fund than in these other target-date funds. In addition to equity securities risk, the fund's other main risk factors are listed below in alphabetical order. &lt;i&gt;Before investing, be sure to read the additional descriptions of these risks beginning on page 68 of the prospectus.&lt;/i&gt;            
            &lt;/div&gt;

               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk based on the nature of their support.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;

               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;

               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;

               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;

               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;

               &lt;b&gt;Target allocation risk.&lt;/b&gt; The fund's risk profile will change due to reallocation or rebalancing of portfolio assets as the fund approaches its target date.&lt;/div&gt;

               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;

               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;

Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide.

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The following information illustrates the variability of the fund's returns and provides some indication of the risks of investing in the fund by showing changes in the fund's performance from year to year and by showing how the fund's average annual returns compared with a broad-based market index. Past performance (before and after taxes) does not indicate future results. All figures assume dividend reinvestment. Performance information is updated daily, monthly, and quarterly and may be obtained at our website, jhinvestments.com, or by calling 888-972-8696 between 8:30 A.M. and 5:00 P.M., Eastern time, on most business days.&lt;/div&gt;

The information shows how the fund's performance compares with the returns of an index of funds with similar investment objectives. From December 1, 2016 to November 30, 2017, the Custom Benchmark consisted of the following indices and approximate weightings: 49.00% Russell 3000 Index, 21.00% MSCI ACWI ex-USA Index, 24.00% Bloomberg Barclays U.S. Aggregate Bond Index, and 6.00% ICE Bank of America Merrill Lynch U.S. High Yield Master II Index. The weightings of the indices in the Custom Benchmark are adjusted annually to reflect changes in the fund's target asset allocation in accordance with the annual roll-down of the glide path described above and differed in periods prior to December 1, 2016.&lt;/div&gt;

Because Class I and Class R5 shares of the fund had not commenced operations as of the date of this prospectus, the returns shown are those of Class 1 shares. Returns for Class I and Class R5 shares would have been substantially similar to returns of Class 1 shares because each share class is invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.&lt;/div&gt;

Your actual after-tax returns may be different. After-tax returns are not relevant to shares held in an IRA, 401(k), or other tax-advantaged investment plan.

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 19% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests substantially all of its assets in underlying funds using an asset allocation strategy designed for investors expected to retire around the year 2030.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The portfolio managers of the fund allocate assets among the underlying funds according to an asset allocation strategy that becomes increasingly conservative over time. John Hancock Multi-Index 2030 Lifetime Portfolio has a target asset allocation of 77% of its assets in underlying funds that invest primarily in equity securities. The fund will have a greater exposure to underlying funds that invest primarily in equity securities than will a John Hancock Multi-Index Lifetime Portfolio with a closer target date. To reduce investment risk and volatility as retirement approaches and in the postretirement years, the asset allocation strategy will change over time according to a predetermined "glide path" shown in the following chart. The fund may be a primary source of income for its shareholders after retirement.&lt;/div&gt;         
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                  GLIDE PATH CHART               
               &lt;/b&gt;&lt;/div&gt;             
&lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;/div&gt;  
                     &lt;img alt="glidepath chart" src="glidepath.jpg"&gt;&lt;/img&gt;   
                
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The allocations reflected in the glide path are referred to as target allocations because they do not reflect active decisions made by the portfolio managers to produce an overweight or an underweight position in a particular asset class. The fund has a target allocation to underlying funds that invest in the broad asset classes of equity and fixed-income securities, but may also allocate its assets to underlying funds that invest outside these asset classes to protect the fund or help it achieve its objective. For example, the fund may also allocate its assets to underlying funds that invest in alternative and specialty asset classes. The managers may change the target allocation without shareholder approval if they believe that such change would benefit the fund and its shareholders. Under normal circumstances, any deviation from the target allocation is not expected to be greater than plus or minus 10%.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Within the prescribed percentage allocation, the managers select the percentage level to be maintained in specific underlying funds. New investments made by the fund may be directed to particular underlying funds in an effort to maintain the desired target allocations. There is no guarantee that the portfolio managers will correctly predict the market or economic conditions and, as with other mutual fund investments, you could lose money even if the fund is at or close to its designated retirement year or in its postretirement stage.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is designed for investors who may remain invested in the fund through their retirement years. The fund will continue to be managed according to an allocation strategy that becomes increasingly conservative over time until approximately twenty years after retirement, at which time the fund expects to maintain a static allocation of approximately 25% of its assets in equity underlying funds.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in underlying funds that invest in a broad range of equity, fixed-income, and alternative/specialty securities and asset classes, including, but not limited to, U.S. and foreign securities, including emerging-market securities, commodities, asset-backed securities, small-cap securities, and below-investment-grade securities (i.e., junk bonds). The underlying funds may also use derivatives, such as swaps, foreign currency forwards, futures, and options, in each case for the purposes of reducing risk, obtaining efficient market exposure and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund will invest in various passively managed underlying funds that as a group hold a wide range of equity-type securities in their portfolios, including convertible securities. The fund may also invest in various actively managed funds. The fund is not designed to track an index or group of indexes. Equity-type securities include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. Certain equity underlying funds may invest in initial public offerings (IPOs). Each of the equity underlying funds has its own investment strategy that, for example, may focus on growth stocks or value stocks, or may employ a strategy combining growth and income stocks, and/or may invest in derivatives such as credit default swaps, foreign currency forwards, interest rate swaps, options on securities, and futures contracts. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from shorter to longer term. The fixed-income underlying funds collectively hold various types of debt instruments such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging market securities). Certain underlying funds may invest in illiquid securities, and certain underlying funds may be non-diversified.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest directly in exchange-traded funds (ETFs), exchange-traded notes (ETNs), the securities of other investment companies, U.S. government securities, and other types of investments such as derivatives, including credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, in each case for the purposes of reducing risk, obtaining efficient market exposure, and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;To the extent permitted by law, the Board of Trustees of the fund may, in its discretion, determine to combine the fund with another fund without shareholder approval if the target allocation of the fund matches the target allocation of the other fund, although there is no assurance that the Board of Trustees will so determine at any point. The fund bears its own expenses and, in addition, indirectly bears its proportionate share of the expenses of the underlying funds in which it invests. The fund's performance reflects both the managers' allocation decisions and the performance of the underlying funds.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Many factors affect performance, and fund shares will fluctuate in price, meaning you could lose money. The fund's investment strategy may not produce the intended results.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;During periods of heightened market volatility or reduced liquidity, governments, their agencies, or other regulatory bodies, both within the United States and abroad, may take steps to intervene. These actions, which could include legislative, regulatory, or economic initiatives, might have unforeseeable consequences and could adversely affect the fund's performance or otherwise constrain the fund's ability to achieve its investment objective.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in equity securities than John Hancock Multi-Index Lifetime Portfolios with closer target dates, equity security risks are more prevalent in this fund than in these other target-date funds. In addition to equity securities risk, the fund's other main risk factors are listed below in alphabetical order. &lt;i&gt;Before investing, be sure to read the additional descriptions of these risks beginning on page 68 of the prospectus.&lt;/i&gt;

               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk based on the nature of their support.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;

               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;

               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;

               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;

The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;

               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;

               &lt;b&gt;Investment company securities risk.&lt;/b&gt; A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;

               &lt;b&gt;Lifecycle risk.&lt;/b&gt; Managers might not correctly predict market or economic conditions, and you could lose money even close to, during, or after the fund's designated retirement year.&lt;/div&gt;

               &lt;b&gt;Target allocation risk.&lt;/b&gt; The fund's risk profile will change due to reallocation or rebalancing of portfolio assets as the fund approaches its target date.&lt;/div&gt;

               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions.

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

The information shows how the fund's performance compares with the returns of an index of funds with similar investment objectives. From December 1, 2016 to November 30, 2017, the Custom Benchmark consisted of the following indices and approximate weightings: 56.70% Russell 3000 Index, 24.30% MSCI ACWI ex-USA Index, 15.20% Bloomberg Barclays U.S. Aggregate Bond Index, and 3.80% ICE Bank of America Merrill Lynch U.S. High Yield Master II Index. The weightings of the indices in the Custom Benchmark are adjusted annually to reflect changes in the fund's target asset allocation in accordance with the annual roll-down of the glide path described above and differed in periods prior to December 1, 2016.&lt;/div&gt;

The example assumes a 5% average annual return and that fund expenses will not change over the periods.

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 15% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests substantially all of its assets in underlying funds using an asset allocation strategy designed for investors expected to retire around the year 2035.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The portfolio managers of the fund allocate assets among the underlying funds according to an asset allocation strategy that becomes increasingly conservative over time. John Hancock Multi-Index 2035 Lifetime Portfolio has a target asset allocation of 86% of its assets in underlying funds that invest primarily in equity securities. The fund will have a greater exposure to underlying funds that invest primarily in equity securities than will a John Hancock Multi-Index Lifetime Portfolio with a closer target date. To reduce investment risk and volatility as retirement approaches and in the postretirement years, the asset allocation strategy will change over time according to a predetermined "glide path" shown in the following chart. The fund may be a primary source of income for its shareholders after retirement.&lt;/div&gt;         
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                  GLIDE PATH CHART               
               &lt;/b&gt;&lt;/div&gt;    
&lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;/div&gt;         
                     &lt;img alt="glidepath chart" src="glidepath.jpg"&gt;&lt;/img&gt;   
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The allocations reflected in the glide path are referred to as target allocations because they do not reflect active decisions made by the portfolio managers to produce an overweight or an underweight position in a particular asset class. The fund has a target allocation to underlying funds that invest in the broad asset classes of equity and fixed-income securities, but may also allocate its assets to underlying funds that invest outside these asset classes to protect the fund or help it achieve its objective. For example, the fund may also allocate its assets to underlying funds that invest in alternative and specialty asset classes. The managers may change the target allocation without shareholder approval if they believe that such change would benefit the fund and its shareholders. Under normal circumstances, any deviation from the target allocation is not expected to be greater than plus or minus 10%.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Within the prescribed percentage allocation, the managers select the percentage level to be maintained in specific underlying funds. New investments made by the fund may be directed to particular underlying funds in an effort to maintain the desired target allocations. There is no guarantee that the portfolio managers will correctly predict the market or economic conditions and, as with other mutual fund investments, you could lose money even if the fund is at or close to its designated retirement year or in its postretirement stage.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is designed for investors who may remain invested in the fund through their retirement years. The fund will continue to be managed according to an allocation strategy that becomes increasingly conservative over time until approximately twenty years after retirement, at which time the fund expects to maintain a static allocation of approximately 25% of its assets in equity underlying funds.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in underlying funds that invest in a broad range of equity, fixed-income, and alternative/specialty securities and asset classes, including, but not limited to, U.S. and foreign securities, including emerging-market securities, commodities, asset-backed securities, small-cap securities, and below-investment-grade securities (i.e., junk bonds). The underlying funds may also use derivatives, such as swaps, foreign currency forwards, futures, and options, in each case for the purposes of reducing risk, obtaining efficient market exposure and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund will invest in various passively managed underlying funds that as a group hold a wide range of equity-type securities in their portfolios, including convertible securities. The fund may also invest in various actively managed funds. The fund is not designed to track an index or group of indexes. Equity-type securities include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. Certain equity underlying funds may invest in initial public offerings (IPOs). Each of the equity underlying funds has its own investment strategy that, for example, may focus on growth stocks or value stocks, or may employ a strategy combining growth and income stocks, and/or may invest in derivatives such as credit default swaps, foreign currency forwards, interest rate swaps, options on securities, and futures contracts. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from shorter to longer term. The fixed-income underlying funds collectively hold various types of debt instruments such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging market securities). Certain underlying funds may invest in illiquid securities, and certain underlying funds may be non-diversified.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest directly in exchange-traded funds (ETFs), exchange-traded notes (ETNs), the securities of other investment companies, U.S. government securities, and other types of investments such as derivatives, including credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, in each case for the purposes of reducing risk, obtaining efficient market exposure, and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;To the extent permitted by law, the Board of Trustees of the fund may, in its discretion, determine to combine the fund with another fund without shareholder approval if the target allocation of the fund matches the target allocation of the other fund, although there is no assurance that the Board of Trustees will so determine at any point. The fund bears its own expenses and, in addition, indirectly bears its proportionate share of the expenses of the underlying funds in which it invests.

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Many factors affect performance, and fund shares will fluctuate in price, meaning you could lose money. The fund's investment strategy may not produce the intended results.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;During periods of heightened market volatility or reduced liquidity, governments, their agencies, or other regulatory bodies, both within the United States and abroad, may take steps to intervene. These actions, which could include legislative, regulatory, or economic initiatives, might have unforeseeable consequences and could adversely affect the fund's performance or otherwise constrain the fund's ability to achieve its investment objective.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in equity securities than John Hancock Multi-Index Lifetime Portfolios with closer target dates, equity security risks are more prevalent in this fund than in these other target-date funds. In addition to equity securities risk, the fund's other main risk factors are listed below in alphabetical order. &lt;i&gt;Before investing, be sure to read the additional descriptions of these risks beginning on page 68 of the prospectus.&lt;/i&gt;            
            &lt;/div&gt;

               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk based on the nature of their support.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;

               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;

               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;

               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;

               &lt;b&gt;Lifecycle risk.&lt;/b&gt; Managers might not correctly predict market or economic conditions, and you could lose money even close to, during, or after the fund's designated retirement year.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Target allocation risk.&lt;/b&gt; The fund's risk profile will change due to reallocation or rebalancing of portfolio assets as the fund approaches its target date.&lt;/div&gt;

               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality.

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;

Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The following information illustrates the variability of the fund's returns and provides some indication of the risks of investing in the fund by showing changes in the fund's performance from year to year and by showing how the fund's average annual returns compared with a broad-based market index. Past performance (before and after taxes) does not indicate future results. All figures assume dividend reinvestment. Performance information is updated daily, monthly, and quarterly and may be obtained at our website, jhinvestments.com, or by calling 888-972-8696 between 8:30 A.M. and 5:00 P.M., Eastern time, on most business days.&lt;/div&gt;

The information shows how the fund's performance compares with the returns of an index of funds with similar investment objectives. From December 1, 2016 to November 30, 2017, the Custom Benchmark consisted of the following indices and approximate weightings: 62.30% Russell 3000 Index, 26.70% MSCI ACWI ex-USA Index, 8.80% Bloomberg Barclays U.S. Aggregate Bond Index, and 2.20% ICE Bank of America Merrill Lynch U.S. High Yield Master II Index. The weightings of the indices in the Custom Benchmark are adjusted annually to reflect changes in the fund's target asset allocation in accordance with the annual roll-down of the glide path described above and differed in periods prior to December 1, 2016.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Class 1 shares commenced operations on November 7, 2013. Because Class I and Class R5 shares of the fund had not commenced operations as of the date of this prospectus, the returns shown are those of Class 1 shares. Returns for Class I and Class R5 shares would have been substantially similar to returns of Class 1 shares because each share class is invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Please note that after-tax returns (shown for Class I shares only) reflect the highest individual federal marginal income-tax rate in effect as of the date provided and do not reflect any state or local taxes. Your actual after-tax returns may be different. After-tax returns are not relevant to shares held in an IRA, 401(k), or other tax-advantaged investment plan. After-tax returns for other share classes would vary.&lt;/div&gt;

An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 15% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests substantially all of its assets in underlying funds using an asset allocation strategy designed for investors expected to retire around the year 2040.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The portfolio managers of the fund allocate assets among the underlying funds according to an asset allocation strategy that becomes increasingly conservative over time. John Hancock Multi-Index 2040 Lifetime Portfolio has a target asset allocation of 93% of its assets in underlying funds that invest primarily in equity securities. The fund will have a greater exposure to underlying funds that invest primarily in equity securities than will a John Hancock Multi-Index Lifetime Portfolio with a closer target date. To reduce investment risk and volatility as retirement approaches and in the postretirement years, the asset allocation strategy will change over time according to a predetermined "glide path" shown in the following chart. The fund may be a primary source of income for its shareholders after retirement.&lt;/div&gt;         
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                  GLIDE PATH CHART               
               &lt;/b&gt;&lt;/div&gt;             
                     &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;/div&gt;   
                  &lt;img alt="glidepath chart" src="glidepath.jpg"&gt;&lt;/img&gt;   
                  
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The allocations reflected in the glide path are referred to as target allocations because they do not reflect active decisions made by the portfolio managers to produce an overweight or an underweight position in a particular asset class. The fund has a target allocation to underlying funds that invest in the broad asset classes of equity and fixed-income securities, but may also allocate its assets to underlying funds that invest outside these asset classes to protect the fund or help it achieve its objective. For example, the fund may also allocate its assets to underlying funds that invest in alternative and specialty asset classes. The managers may change the target allocation without shareholder approval if they believe that such change would benefit the fund and its shareholders. Under normal circumstances, any deviation from the target allocation is not expected to be greater than plus or minus 10%.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Within the prescribed percentage allocation, the managers select the percentage level to be maintained in specific underlying funds. New investments made by the fund may be directed to particular underlying funds in an effort to maintain the desired target allocations. There is no guarantee that the portfolio managers will correctly predict the market or economic conditions and, as with other mutual fund investments, you could lose money even if the fund is at or close to its designated retirement year or in its postretirement stage.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is designed for investors who may remain invested in the fund through their retirement years. The fund will continue to be managed according to an allocation strategy that becomes increasingly conservative over time until approximately twenty years after retirement, at which time the fund expects to maintain a static allocation of approximately 25% of its assets in equity underlying funds.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in underlying funds that invest in a broad range of equity, fixed-income, and alternative/specialty securities and asset classes, including, but not limited to, U.S. and foreign securities, including emerging-market securities, commodities, asset-backed securities, small-cap securities, and below-investment-grade securities (i.e., junk bonds). The underlying funds may also use derivatives, such as swaps, foreign currency forwards, futures, and options, in each case for the purposes of reducing risk, obtaining efficient market exposure and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund will invest in various passively managed underlying funds that as a group hold a wide range of equity-type securities in their portfolios, including convertible securities. The fund may also invest in various actively managed funds. The fund is not designed to track an index or group of indexes. Equity-type securities include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. Certain equity underlying funds may invest in initial public offerings (IPOs). Each of the equity underlying funds has its own investment strategy that, for example, may focus on growth stocks or value stocks, or may employ a strategy combining growth and income stocks, and/or may invest in derivatives such as credit default swaps, foreign currency forwards, interest rate swaps, options on securities, and futures contracts. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from shorter to longer term. The fixed-income underlying funds collectively hold various types of debt instruments such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging market securities). Certain underlying funds may invest in illiquid securities, and certain underlying funds may be non-diversified.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest directly in exchange-traded funds (ETFs), exchange-traded notes (ETNs), the securities of other investment companies, U.S. government securities, and other types of investments such as derivatives, including credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, in each case for the purposes of reducing risk, obtaining efficient market exposure, and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;To the extent permitted by law, the Board of Trustees of the fund may, in its discretion, determine to combine the fund with another fund without shareholder approval if the target allocation of the fund matches the target allocation of the other fund, although there is no assurance that the Board of Trustees will so determine at any point. The fund bears its own expenses and, in addition, indirectly bears its proportionate share of the expenses of the underlying funds in which it invests. The fund's performance reflects both the managers' allocation decisions and the performance of the underlying funds.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Many factors affect performance, and fund shares will fluctuate in price, meaning you could lose money. The fund's investment strategy may not produce the intended results.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;During periods of heightened market volatility or reduced liquidity, governments, their agencies, or other regulatory bodies, both within the United States and abroad, may take steps to intervene. These actions, which could include legislative, regulatory, or economic initiatives, might have unforeseeable consequences and could adversely affect the fund's performance or otherwise constrain the fund's ability to achieve its investment objective.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in equity securities than John Hancock Multi-Index Lifetime Portfolios with closer target dates, equity security risks are more prevalent in this fund than in these other target-date funds. In addition to equity securities risk, the fund's other main risk factors are listed below in alphabetical order. &lt;i&gt;Before investing, be sure to read the additional descriptions of these risks beginning on page 68 of the prospectus.&lt;/i&gt;            
            &lt;/div&gt;

               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk based on the nature of their support.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;

               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;

               &lt;b&gt;Target allocation risk.&lt;/b&gt; The fund's risk profile will change due to reallocation or rebalancing of portfolio assets as the fund approaches its target date.&lt;/div&gt;

               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality.

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment.

Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;

               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;

               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The following information illustrates the variability of the fund's returns and provides some indication of the risks of investing in the fund by showing changes in the fund's performance from year to year and by showing how the fund's average annual returns compared with a broad-based market index. Past performance (before and after taxes) does not indicate future results. All figures assume dividend reinvestment. Performance information is updated daily, monthly, and quarterly and may be obtained at our website, jhinvestments.com, or by calling 888-972-8696 between 8:30 A.M. and 5:00 P.M., Eastern time, on most business days.&lt;/div&gt;

The information shows how the fund's performance compares with the returns of an index of funds with similar investment objectives. From November 7, 2013 to November 30, 2017, the Custom Benchmark consisted of the following indices and approximate weightings: 66.50% Russell 3000 Index, 28.50% MSCI ACWI ex-USA Index, 4.00% Bloomberg Barclays U.S. Aggregate Bond Index, and 1.00% ICE Bank of America Merrill Lynch U.S. High Yield Master II Index. The weightings of the indices in the Custom Benchmark are adjusted annually to reflect changes in the fund's target asset allocation in accordance with the annual roll-down of the glide path described above.&lt;/div&gt;

Because Class I and Class R5 shares of the fund had not commenced operations as of the date of this prospectus, the returns shown are those of Class 1 shares. Returns for Class I and Class R5 shares would have been substantially similar to returns of Class 1 shares because each share class is invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.&lt;/div&gt;

Your actual after-tax returns may be different. After-tax returns are not relevant to shares held in an IRA, 401(k), or other tax-advantaged investment plan. After-tax returns for other share classes would vary.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 12% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests substantially all of its assets in underlying funds using an asset allocation strategy designed for investors expected to retire around the year 2045.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The portfolio managers of the fund allocate assets among the underlying funds according to an asset allocation strategy that becomes increasingly conservative over time. John Hancock Multi-Index 2045 Lifetime Portfolio has a target asset allocation of 95% of its assets in underlying funds that invest primarily in equity securities. The fund will have a greater exposure to underlying funds that invest primarily in equity securities than will a John Hancock Multi-Index Lifetime Portfolio with a closer target date. To reduce investment risk and volatility as retirement approaches and in the postretirement years, the asset allocation strategy will change over time according to a predetermined "glide path" shown in the following chart. The fund may be a primary source of income for its shareholders after retirement.&lt;/div&gt;          
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                  GLIDE PATH CHART               
               &lt;/b&gt;&lt;/div&gt;             
 &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;/div&gt;     
                     &lt;img alt="glidepath chart" src="glidepath.jpg"&gt;&lt;/img&gt;   
                  
               
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The allocations reflected in the glide path are referred to as target allocations because they do not reflect active decisions made by the portfolio managers to produce an overweight or an underweight position in a particular asset class. The fund has a target allocation to underlying funds that invest in the broad asset classes of equity and fixed-income securities, but may also allocate its assets to underlying funds that invest outside these asset classes to protect the fund or help it achieve its objective. For example, the fund may also allocate its assets to underlying funds that invest in alternative and specialty asset classes. The managers may change the target allocation without shareholder approval if they believe that such change would benefit the fund and its shareholders. Under normal circumstances, any deviation from the target allocation is not expected to be greater than plus or minus 10%.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Within the prescribed percentage allocation, the managers select the percentage level to be maintained in specific underlying funds. New investments made by the fund may be directed to particular underlying funds in an effort to maintain the desired target allocations. There is no guarantee that the portfolio managers will correctly predict the market or economic conditions and, as with other mutual fund investments, you could lose money even if the fund is at or close to its designated retirement year or in its postretirement stage.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is designed for investors who may remain invested in the fund through their retirement years. The fund will continue to be managed according to an allocation strategy that becomes increasingly conservative over time until approximately twenty years after retirement, at which time the fund expects to maintain a static allocation of approximately 25% of its assets in equity underlying funds.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in underlying funds that invest in a broad range of equity, fixed-income, and alternative/specialty securities and asset classes, including, but not limited to, U.S. and foreign securities, including emerging-market securities, commodities, asset-backed securities, small-cap securities, and below-investment-grade securities (i.e., junk bonds). The underlying funds may also use derivatives, such as swaps, foreign currency forwards, futures, and options, in each case for the purposes of reducing risk, obtaining efficient market exposure and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund will invest in various passively managed underlying funds that as a group hold a wide range of equity-type securities in their portfolios, including convertible securities. The fund may also invest in various actively managed funds. The fund is not designed to track an index or group of indexes. Equity-type securities include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. Certain equity underlying funds may invest in initial public offerings (IPOs). Each of the equity underlying funds has its own investment strategy that, for example, may focus on growth stocks or value stocks, or may employ a strategy combining growth and income stocks, and/or may invest in derivatives such as credit default swaps, foreign currency forwards, interest rate swaps, options on securities, and futures contracts. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from shorter to longer term. The fixed-income underlying funds collectively hold various types of debt instruments such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging market securities). Certain underlying funds may invest in illiquid securities, and certain underlying funds may be non-diversified.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest directly in exchange-traded funds (ETFs), exchange-traded notes (ETNs), the securities of other investment companies, U.S. government securities, and other types of investments such as derivatives, including credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, in each case for the purposes of reducing risk, obtaining efficient market exposure, and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;To the extent permitted by law, the Board of Trustees of the fund may, in its discretion, determine to combine the fund with another fund without shareholder approval if the target allocation of the fund matches the target allocation of the other fund, although there is no assurance that the Board of Trustees will so determine at any point. The fund bears its own expenses and, in addition, indirectly bears its proportionate share of the expenses of the underlying funds in which it invests. The fund's performance reflects both the managers' allocation decisions and the performance of the underlying funds.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Many factors affect performance, and fund shares will fluctuate in price, meaning you could lose money. The fund's investment strategy may not produce the intended results.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;During periods of heightened market volatility or reduced liquidity, governments, their agencies, or other regulatory bodies, both within the United States and abroad, may take steps to intervene. These actions, which could include legislative, regulatory, or economic initiatives, might have unforeseeable consequences and could adversely affect the fund's performance or otherwise constrain the fund's ability to achieve its investment objective.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in equity securities than John Hancock Multi-Index Lifetime Portfolios with closer target dates, equity security risks are more prevalent in this fund than in these other target-date funds. In addition to equity securities risk, the fund's other main risk factors are listed below in alphabetical order. &lt;i&gt;Before investing, be sure to read the additional descriptions of these risks beginning on page 68 of the prospectus.&lt;/i&gt;

               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk based on the nature of their support.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;

               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;

               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;

               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;

               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;

               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation.

               &lt;b&gt;Target allocation risk.&lt;/b&gt; The fund's risk profile will change due to reallocation or rebalancing of portfolio assets as the fund approaches its target date.&lt;/div&gt;

               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

The information shows how the fund's performance compares with the returns of an index of funds with similar investment objectives. From November 7, 2013 to November 30, 2017, the Custom Benchmark consisted of the following indices and approximate weightings: 66.50% Russell 3000 Index, 28.50% MSCI ACWI ex-USA Index, 4.00% Bloomberg Barclays U.S. Aggregate Bond Index, and 1.00% ICE Bank of America Merrill Lynch U.S. High Yield Master II Index. The weightings of the indices in the Custom Benchmark are adjusted annually to reflect changes in the fund's target asset allocation in accordance with the annual roll-down of the glide path described above.&lt;/div&gt;

Because Class I and Class R5 shares of the fund had not commenced operations as of the date of this prospectus, the returns shown are those of Class 1 shares. Returns for Class I and Class R5 shares would have been substantially similar to returns of Class 1 shares because each share class is invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.&lt;/div&gt;

The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 14% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests substantially all of its assets in underlying funds using an asset allocation strategy designed for investors expected to retire around the year 2050.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The portfolio managers of the fund allocate assets among the underlying funds according to an asset allocation strategy that becomes increasingly conservative over time. John Hancock Multi-Index 2050 Lifetime Portfolio has a target asset allocation of 95% of its assets in underlying funds that invest primarily in equity securities. The fund will have a greater exposure to underlying funds that invest primarily in equity securities than will a John Hancock Multi-Index Lifetime Portfolio with a closer target date. To reduce investment risk and volatility as retirement approaches and in the postretirement years, the asset allocation strategy will change over time according to a predetermined "glide path" shown in the following chart. The fund may be a primary source of income for its shareholders after retirement.&lt;/div&gt;          
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                  GLIDE PATH CHART               
               &lt;/b&gt;&lt;/div&gt;   
&lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;/div&gt;          
                   &lt;img alt="glidepath chart" src="glidepath.jpg"&gt;&lt;/img&gt;     
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The allocations reflected in the glide path are referred to as target allocations because they do not reflect active decisions made by the portfolio managers to produce an overweight or an underweight position in a particular asset class. The fund has a target allocation to underlying funds that invest in the broad asset classes of equity and fixed-income securities, but may also allocate its assets to underlying funds that invest outside these asset classes to protect the fund or help it achieve its objective. For example, the fund may also allocate its assets to underlying funds that invest in alternative and specialty asset classes. The managers may change the target allocation without shareholder approval if they believe that such change would benefit the fund and its shareholders. Under normal circumstances, any deviation from the target allocation is not expected to be greater than plus or minus 10%.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Within the prescribed percentage allocation, the managers select the percentage level to be maintained in specific underlying funds. New investments made by the fund may be directed to particular underlying funds in an effort to maintain the desired target allocations. There is no guarantee that the portfolio managers will correctly predict the market or economic conditions and, as with other mutual fund investments, you could lose money even if the fund is at or close to its designated retirement year or in its postretirement stage.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is designed for investors who may remain invested in the fund through their retirement years. The fund will continue to be managed according to an allocation strategy that becomes increasingly conservative over time until approximately twenty years after retirement, at which time the fund expects to maintain a static allocation of approximately 25% of its assets in equity underlying funds.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in underlying funds that invest in a broad range of equity, fixed-income, and alternative/specialty securities and asset classes, including, but not limited to, U.S. and foreign securities, including emerging-market securities, commodities, asset-backed securities, small-cap securities, and below-investment-grade securities (i.e., junk bonds). The underlying funds may also use derivatives, such as swaps, foreign currency forwards, futures, and options, in each case for the purposes of reducing risk, obtaining efficient market exposure and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund will invest in various passively managed underlying funds that as a group hold a wide range of equity-type securities in their portfolios, including convertible securities. The fund may also invest in various actively managed funds. The fund is not designed to track an index or group of indexes. Equity-type securities include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. Certain equity underlying funds may invest in initial public offerings (IPOs). Each of the equity underlying funds has its own investment strategy that, for example, may focus on growth stocks or value stocks, or may employ a strategy combining growth and income stocks, and/or may invest in derivatives such as credit default swaps, foreign currency forwards, interest rate swaps, options on securities, and futures contracts. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from shorter to longer term. The fixed-income underlying funds collectively hold various types of debt instruments such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging market securities). Certain underlying funds may invest in illiquid securities, and certain underlying funds may be non-diversified.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest directly in exchange-traded funds (ETFs), exchange-traded notes (ETNs), the securities of other investment companies, U.S. government securities, and other types of investments such as derivatives, including credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, in each case for the purposes of reducing risk, obtaining efficient market exposure, and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;To the extent permitted by law, the Board of Trustees of the fund may, in its discretion, determine to combine the fund with another fund without shareholder approval if the target allocation of the fund matches the target allocation of the other fund, although there is no assurance that the Board of Trustees will so determine at any point. The fund bears its own expenses and, in addition, indirectly bears its proportionate share of the expenses of the underlying funds in which it invests. The fund's performance reflects both the managers' allocation decisions and the performance of the underlying funds.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Many factors affect performance, and fund shares will fluctuate in price, meaning you could lose money. The fund's investment strategy may not produce the intended results.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;During periods of heightened market volatility or reduced liquidity, governments, their agencies, or other regulatory bodies, both within the United States and abroad, may take steps to intervene. These actions, which could include legislative, regulatory, or economic initiatives, might have unforeseeable consequences and could adversely affect the fund's performance or otherwise constrain the fund's ability to achieve its investment objective.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in equity securities than John Hancock Multi-Index Lifetime Portfolios with closer target dates, equity security risks are more prevalent in this fund than in these other target-date funds. In addition to equity securities risk, the fund's other main risk factors are listed below in alphabetical order. &lt;i&gt;Before investing, be sure to read the additional descriptions of these risks beginning on page 68 of the prospectus.&lt;/i&gt;            
            &lt;/div&gt;

                  &lt;i&gt;Principal risks of investing in the fund of funds  &lt;/i&gt;             
               &lt;/b&gt;&lt;/div&gt;

               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk based on the nature of their support.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;

               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;

               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Investment company securities risk.&lt;/b&gt; A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lifecycle risk.&lt;/b&gt; Managers might not correctly predict market or economic conditions, and you could lose money even close to, during, or after the fund's designated retirement year.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Target allocation risk.&lt;/b&gt; The fund's risk profile will change due to reallocation or rebalancing of portfolio assets as the fund approaches its target date.&lt;/div&gt;

                &lt;i&gt;  Principal risks of investing in the underlying funds  &lt;/i&gt;             
               &lt;/b&gt;&lt;/div&gt;             
                     
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

The information shows how the fund's performance compares with the returns of an index of funds with similar investment objectives. From November 7, 2013 to November 30, 2017, the Custom Benchmark consisted of the following indices and approximate weightings: 66.50% Russell 3000 Index, 28.50% MSCI ACWI ex-USA Index, 4.00% Bloomberg Barclays U.S. Aggregate Bond Index, and 1.00% ICE Bank of America Merrill Lynch U.S. High Yield Master II Index. The weightings of the indices in the Custom Benchmark are adjusted annually to reflect changes in the fund's target asset allocation in accordance with the annual roll-down of the glide path described above.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Class 1 shares commenced operations on November 7, 2013. Because Class I and Class R5 shares of the fund had not commenced operations as of the date of this prospectus, the returns shown are those of Class 1 shares. Returns for Class I and Class R5 shares would have been substantially similar to returns of Class 1 shares because each share class is invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.&lt;/div&gt;

Your actual after-tax returns may be different. After-tax returns are not relevant to shares held in an IRA, 401(k), or other tax-advantaged investment plan. After-tax returns for other share classes would vary.&lt;/div&gt;

The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 17% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests substantially all of its assets in underlying funds using an asset allocation strategy designed for investors expected to retire around the year 2055.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The portfolio managers of the fund allocate assets among the underlying funds according to an asset allocation strategy that becomes increasingly conservative over time. John Hancock Multi-Index 2055 Lifetime Portfolio has a target asset allocation of 95% of its assets in underlying funds that invest primarily in equity securities. The fund will have a greater exposure to underlying funds that invest primarily in equity securities than will a John Hancock Multi-Index Lifetime Portfolio with a closer target date. To reduce investment risk and volatility as retirement approaches and in the postretirement years, the asset allocation strategy will change over time according to a predetermined "glide path" shown in the following chart. The fund may be a primary source of income for its shareholders after retirement.&lt;/div&gt;          
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                  GLIDE PATH CHART               
               &lt;/b&gt;&lt;/div&gt;  
&lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;/div&gt;           
                    &lt;img alt="glidepath chart" src="glidepath.jpg"&gt;&lt;/img&gt;    
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The allocations reflected in the glide path are referred to as target allocations because they do not reflect active decisions made by the portfolio managers to produce an overweight or an underweight position in a particular asset class. The fund has a target allocation to underlying funds that invest in the broad asset classes of equity and fixed-income securities, but may also allocate its assets to underlying funds that invest outside these asset classes to protect the fund or help it achieve its objective. For example, the fund may also allocate its assets to underlying funds that invest in alternative and specialty asset classes. The managers may change the target allocation without shareholder approval if they believe that such change would benefit the fund and its shareholders. Under normal circumstances, any deviation from the target allocation is not expected to be greater than plus or minus 10%.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Within the prescribed percentage allocation, the managers select the percentage level to be maintained in specific underlying funds. New investments made by the fund may be directed to particular underlying funds in an effort to maintain the desired target allocations. There is no guarantee that the portfolio managers will correctly predict the market or economic conditions and, as with other mutual fund investments, you could lose money even if the fund is at or close to its designated retirement year or in its postretirement stage.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is designed for investors who may remain invested in the fund through their retirement years. The fund will continue to be managed according to an allocation strategy that becomes increasingly conservative over time until approximately twenty years after retirement, at which time the fund expects to maintain a static allocation of approximately 25% of its assets in equity underlying funds.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in underlying funds that invest in a broad range of equity, fixed-income, and alternative/specialty securities and asset classes, including, but not limited to, U.S. and foreign securities, including emerging-market securities, commodities, asset-backed securities, small-cap securities, and below-investment-grade securities (i.e., junk bonds). The underlying funds may also use derivatives, such as swaps, foreign currency forwards, futures, and options, in each case for the purposes of reducing risk, obtaining efficient market exposure and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund will invest in various passively managed underlying funds that as a group hold a wide range of equity-type securities in their portfolios, including convertible securities. The fund may also invest in various actively managed funds. The fund is not designed to track an index or group of indexes. Equity-type securities include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. Certain equity underlying funds may invest in initial public offerings (IPOs). Each of the equity underlying funds has its own investment strategy that, for example, may focus on growth stocks or value stocks, or may employ a strategy combining growth and income stocks, and/or may invest in derivatives such as credit default swaps, foreign currency forwards, interest rate swaps, options on securities, and futures contracts. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from shorter to longer term. The fixed-income underlying funds collectively hold various types of debt instruments such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging market securities). Certain underlying funds may invest in illiquid securities, and certain underlying funds may be non-diversified.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest directly in exchange-traded funds (ETFs), exchange-traded notes (ETNs), the securities of other investment companies, U.S. government securities, and other types of investments such as derivatives, including credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, in each case for the purposes of reducing risk, obtaining efficient market exposure, and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;To the extent permitted by law, the Board of Trustees of the fund may, in its discretion, determine to combine the fund with another fund without shareholder approval if the target allocation of the fund matches the target allocation of the other fund, although there is no assurance that the Board of Trustees will so determine at any point. The fund bears its own expenses and, in addition, indirectly bears its proportionate share of the expenses of the underlying funds in which it invests. The fund's performance reflects both the managers' allocation decisions and the performance of the underlying funds.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Many factors affect performance, and fund shares will fluctuate in price, meaning you could lose money. The fund's investment strategy may not produce the intended results.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;During periods of heightened market volatility or reduced liquidity, governments, their agencies, or other regulatory bodies, both within the United States and abroad, may take steps to intervene. These actions, which could include legislative, regulatory, or economic initiatives, might have unforeseeable consequences and could adversely affect the fund's performance or otherwise constrain the fund's ability to achieve its investment objective.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in equity securities than John Hancock Multi-Index Lifetime Portfolios with closer target dates, equity security risks are more prevalent in this fund than in these other target-date funds. In addition to equity securities risk, the fund's other main risk factors are listed below in alphabetical order. &lt;i&gt;Before investing, be sure to read the additional descriptions of these risks beginning on page 68 of the prospectus.&lt;/i&gt;            
            &lt;/div&gt;

               &lt;/b&gt;&lt;/div&gt;

               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk based on the nature of their support.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;

               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;

               &lt;b&gt;Lifecycle risk.&lt;/b&gt; Managers might not correctly predict market or economic conditions, and you could lose money even close to, during, or after the fund's designated retirement year.&lt;/div&gt;

               &lt;b&gt;Target allocation risk.&lt;/b&gt; The fund's risk profile will change due to reallocation or rebalancing of portfolio assets as the fund approaches its target date.&lt;/div&gt;

               &lt;i&gt;   Principal risks of investing in the underlying funds   &lt;/i&gt;            
               &lt;/b&gt;&lt;/div&gt;             
                     
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;

               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;

               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;

               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;

               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;

               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;

               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;

               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;

               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;

               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The following information illustrates the variability of the fund's returns and provides some indication of the risks of investing in the fund by showing changes in the fund's performance from year to year and by showing how the fund's average annual returns compared with a broad-based market index. Past performance (before and after taxes) does not indicate future results. All figures assume dividend reinvestment. Performance information is updated daily, monthly, and quarterly and may be obtained at our website, jhinvestments.com, or by calling 888-972-8696 between 8:30 A.M. and 5:00 P.M., Eastern time, on most business days.&lt;/div&gt;

The information shows how the fund's performance compares with the returns of an index of funds with similar investment objectives. From March 26, 2014 to November 30, 2017, the Custom Benchmark consisted of the following indices and approximate weightings: 66.50% Russell 3000 Index, 28.50% MSCI ACWI ex-USA Index, 4.00% Bloomberg Barclays U.S. Aggregate Bond Index, and 1.00% ICE Bank of America Merrill Lynch U.S. High Yield Master II Index. The weightings of the indices in the Custom Benchmark are adjusted annually to reflect changes in the fund's target asset allocation in accordance with the annual rolldown of the glide path described above.&lt;/div&gt;

Because Class I and Class R5 shares of the fund had not commenced operations as of the date of this prospectus, the returns shown are those of Class 1 shares. Returns for Class I and Class R5 shares would have been substantially similar to returns of Class 1 shares because each share class is invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.&lt;/div&gt;

Your actual after-tax returns may be different. After-tax returns are not relevant to shares held in an IRA, 401(k), or other tax-advantaged investment plan. After-tax returns for other share classes would vary.&lt;/div&gt;

The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 24% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests substantially all of its assets in underlying funds using an asset allocation strategy designed for investors expected to retire around the year 2060.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The portfolio managers of the fund allocate assets among the underlying funds according to an asset allocation strategy that becomes increasingly conservative over time. John Hancock Multi-Index 2060 Lifetime Portfolio has a target asset allocation of 95% of its assets in underlying funds that invest primarily in equity securities. The fund will have a greater exposure to underlying funds that invest primarily in equity securities than will a John Hancock Multi-Index Lifetime Portfolio with a closer target date. To reduce investment risk and volatility as retirement approaches and in the postretirement years, the asset allocation strategy will change over time according to a predetermined "glide path" shown in the following chart. The fund may be a primary source of income for its shareholders after retirement.&lt;/div&gt;          
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                  GLIDE PATH CHART               
               &lt;/b&gt;&lt;/div&gt;    
 &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;/div&gt;           
                     &lt;img alt="glidepath chart" src="glidepath.jpg"&gt;&lt;/img&gt;   
       &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;/div&gt;           
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The allocations reflected in the glide path are referred to as target allocations because they do not reflect active decisions made by the portfolio managers to produce an overweight or an underweight position in a particular asset class. The fund has a target allocation to underlying funds that invest in the broad asset classes of equity and fixed-income securities, but may also allocate its assets to underlying funds that invest outside these asset classes to protect the fund or help it achieve its objective. For example, the fund may also allocate its assets to underlying funds that invest in alternative and specialty asset classes. The managers may change the target allocation without shareholder approval if they believe that such change would benefit the fund and its shareholders. Under normal circumstances, any deviation from the target allocation is not expected to be greater than plus or minus 10%.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Within the prescribed percentage allocation, the managers select the percentage level to be maintained in specific underlying funds. New investments made by the fund may be directed to particular underlying funds in an effort to maintain the desired target allocations. There is no guarantee that the portfolio managers will correctly predict the market or economic conditions and, as with other mutual fund investments, you could lose money even if the fund is at or close to its designated retirement year or in its postretirement stage.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is designed for investors who may remain invested in the fund through their retirement years. The fund will continue to be managed according to an allocation strategy that becomes increasingly conservative over time until approximately twenty years after retirement, at which time the fund expects to maintain a static allocation of approximately 25% of its assets in equity underlying funds.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in underlying funds that invest in a broad range of equity, fixed-income, and alternative/specialty securities and asset classes, including, but not limited to, U.S. and foreign securities, including emerging-market securities, commodities, asset-backed securities, small-cap securities, and below-investment-grade securities (i.e., junk bonds). The underlying funds may also use derivatives, such as swaps, foreign currency forwards, futures, and options, in each case for the purposes of reducing risk, obtaining efficient market exposure and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund will invest in various passively managed underlying funds that as a group hold a wide range of equity-type securities in their portfolios, including convertible securities. The fund may also invest in various actively managed funds. The fund is not designed to track an index or group of indexes. Equity-type securities include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. Certain equity underlying funds may invest in initial public offerings (IPOs). Each of the equity underlying funds has its own investment strategy that, for example, may focus on growth stocks or value stocks, or may employ a strategy combining growth and income stocks, and/or may invest in derivatives such as credit default swaps, foreign currency forwards, interest rate swaps, options on securities, and futures contracts. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from shorter to longer term. The fixed-income underlying funds collectively hold various types of debt instruments such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging market securities). Certain underlying funds may invest in illiquid securities, and certain underlying funds may be non-diversified.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest directly in exchange-traded funds (ETFs), exchange-traded notes (ETNs), the securities of other investment companies, U.S. government securities, and other types of investments such as derivatives, including credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, in each case for the purposes of reducing risk, obtaining efficient market exposure, and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;To the extent permitted by law, the Board of Trustees of the fund may, in its discretion, determine to combine the fund with another fund without shareholder approval if the target allocation of the fund matches the target allocation of the other fund, although there is no assurance that the Board of Trustees will so determine at any point. The fund bears its own expenses and, in addition, indirectly bears its proportionate share of the expenses of the underlying funds in which it invests. The fund's performance reflects both the managers' allocation decisions and the performance of the underlying funds.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Many factors affect performance, and fund shares will fluctuate in price, meaning you could lose money. The fund's investment strategy may not produce the intended results.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;During periods of heightened market volatility or reduced liquidity, governments, their agencies, or other regulatory bodies, both within the United States and abroad, may take steps to intervene. These actions, which could include legislative, regulatory, or economic initiatives, might have unforeseeable consequences and could adversely affect the fund's performance or otherwise constrain the fund's ability to achieve its investment objective.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in equity securities than John Hancock Multi-Index Lifetime Portfolios with closer target dates, equity security risks are more prevalent in this fund than in these other target-date funds. In addition to equity securities risk, the fund's other main risk factors are listed below in alphabetical order. &lt;i&gt;Before investing, be sure to read the additional descriptions of these risks beginning on page 68 of the prospectus.&lt;/i&gt;

               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk based on the nature of their support.&lt;/div&gt;

               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;

               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;

               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;

               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;

               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;

               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;

               &lt;b&gt;Target allocation risk.&lt;/b&gt; The fund's risk profile will change due to reallocation or rebalancing of portfolio assets as the fund approaches its target date.&lt;/div&gt;

               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

The information shows how the fund's performance compares with the returns of an index of funds with similar investment objectives. From March 30, 2016 to November 30, 2017, the Custom Benchmark consisted of the following indices and approximate weightings: 66.50% Russell 3000 Index, 28.50% MSCI ACWI ex-USA Index, 4.00% Bloomberg Barclays U.S. Aggregate Bond Index, and 1.00% ICE Bank of America Merrill Lynch U.S. High Yield Master II Index. The weightings of the indices in the Custom Benchmark are adjusted annually to reflect changes in the fund's target asset allocation in accordance with the annual rolldown of the glide path described above.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 49% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests substantially all of its assets in underlying funds using an asset allocation strategy designed for investors expected to retire around the year 2010.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The portfolio managers of the fund allocate assets among the underlying funds according to an asset allocation strategy that becomes increasingly conservative over time. John Hancock Multi-Index 2010 Lifetime Portfolio has a target asset allocation of 38.75% of its assets in underlying funds that invest primarily in equity securities. The fund will have a greater exposure to underlying funds that invest primarily in fixed-income securities than will a John Hancock Multi-Index Lifetime Portfolio with a more distant target date. To reduce investment risk and volatility as retirement approaches and in the postretirement years, the asset allocation strategy will change over time according to a predetermined "glide path" shown in the following chart. The fund may be a primary source of income for its shareholders after retirement.&lt;/div&gt;         
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                  GLIDE PATH CHART               
               &lt;/b&gt;&lt;/div&gt;             
                     &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;/div&gt; 
                  &lt;img alt="glidepath chart" src="glidepath.jpg"&gt;&lt;/img&gt;   
                     

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The allocations reflected in the glide path are referred to as target allocations because they do not reflect active decisions made by the portfolio managers to produce an overweight or an underweight position in a particular asset class. The fund has a target allocation to underlying funds that invest in the broad asset classes of equity and fixed-income securities, but may also allocate its assets to underlying funds that invest outside these asset classes to protect the fund or help it achieve its objective. For example, the fund may also allocate its assets to underlying funds that invest in alternative and specialty asset classes. The managers may change the target allocation without shareholder approval if they believe that such change would benefit the fund and its shareholders. Under normal circumstances, any deviation from the target allocation is not expected to be greater than plus or minus 10%.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Within the prescribed percentage allocation, the managers select the percentage level to be maintained in specific underlying funds. New investments made by the fund may be directed to particular underlying funds in an effort to maintain the desired target allocations. There is no guarantee that the portfolio managers will correctly predict the market or economic conditions and, as with other mutual fund investments, you could lose money even if the fund is at or close to its designated retirement year or in its postretirement stage.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is designed for investors who may remain invested in the fund through their retirement years. The fund will continue to be managed according to an allocation strategy that becomes increasingly conservative over time until approximately twenty years after retirement, at which time the fund expects to maintain a static allocation of approximately 25% of its assets in equity underlying funds.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in underlying funds that invest in a broad range of equity, fixed-income, and alternative/specialty securities and asset classes, including, but not limited to, U.S. and foreign securities, including emerging-market securities, commodities, asset-backed securities, small-cap securities, and below-investment-grade securities (i.e., junk bonds). The underlying funds may also use derivatives, such as swaps, foreign currency forwards, futures, and options, in each case for the purposes of reducing risk, obtaining efficient market exposure and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund will invest in various passively managed underlying funds that as a group hold a wide range of equity-type securities in their portfolios, including convertible securities. The fund may also invest in various actively managed funds. The fund is not designed to track an index or group of indexes. Equity-type securities include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. Certain equity underlying funds may invest in initial public offerings (IPOs). Each of the equity underlying funds has its own investment strategy that, for example, may focus on growth stocks or value stocks, or may employ a strategy combining growth and income stocks, and/or may invest in derivatives such as credit default swaps, foreign currency forwards, interest rate swaps, options on securities, and futures contracts. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from shorter to longer term. The fixed-income underlying funds collectively hold various types of debt instruments such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging market securities). Certain underlying funds may invest in illiquid securities, and certain underlying funds may be non-diversified.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest directly in exchange-traded funds (ETFs), exchange-traded notes (ETNs), the securities of other investment companies, U.S. government securities, and other types of investments such as derivatives, including credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, in each case for the purposes of reducing risk, obtaining efficient market exposure, and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;To the extent permitted by law, the Board of Trustees of the fund may, in its discretion, determine to combine the fund with another fund without shareholder approval if the target allocation of the fund matches the target allocation of the other fund, although there is no assurance that the Board of Trustees will so determine at any point. The fund bears its own expenses and, in addition, indirectly bears its proportionate share of the expenses of the underlying funds in which it invests. The fund's performance reflects both the managers' allocation decisions and the performance of the underlying funds.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Many factors affect performance, and fund shares will fluctuate in price, meaning you could lose money. The fund's investment strategy may not produce the intended results.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;During periods of heightened market volatility or reduced liquidity, governments, their agencies, or other regulatory bodies, both within the United States and abroad, may take steps to intervene. These actions, which could include legislative, regulatory, or economic initiatives, might have unforeseeable consequences and could adversely affect the fund's performance or otherwise constrain the fund's ability to achieve its investment objective.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in fixed-income securities than John Hancock Multi-Index Lifetime Portfolios with target dates that are more distant, fixed-income securities risks are more prevalent in this fund than in these other target-date funds. In addition to fixed-income securities risk, the fund's other main risk factors are listed below in alphabetical order. &lt;i&gt;Before investing, be sure to read the additional descriptions of these risks beginning on page 68 of the prospectus.&lt;/i&gt;

               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk based on the nature of their support.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Investment company securities risk.&lt;/b&gt; A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lifecycle risk.&lt;/b&gt; Managers might not correctly predict market or economic conditions, and you could lose money even close to, during, or after the fund's designated retirement year.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Target allocation risk.&lt;/b&gt; The fund's risk profile will change due to reallocation or rebalancing of portfolio assets as the fund approaches its target date.&lt;/div&gt;

                &lt;i&gt;  Principal risks of investing in the underlying funds    &lt;/i&gt;           
               &lt;/b&gt;&lt;/div&gt;             
                     
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's Board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

The information shows how the fund's performance compares with the returns of an index of funds with similar investment objectives. From December 1, 2016 to November 30, 2017, the Custom Benchmark consisted of the following indices and approximate weightings: 28.88% Russell 3000 Index, 12.37% MSCI ACWI ex-USA Index, 47.00% Bloomberg Barclays U.S. Aggregate Bond Index, and 11.75% ICE Bank of America Merrill Lynch U.S. High Yield Master II Index. The weightings of the indices in the Custom Benchmark are adjusted annually to reflect changes in the fund's target asset allocation in accordance with the annual roll-down of the glide path described above and differed in periods prior to December 1, 2016.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Class R4 shares ceased operations as of June 15, 2016 and resumed on April 7, 2017. Returns for Class R4 shares between those dates are those of Class 1 shares. Returns for Class R4 shares would have been substantially similar to returns of Class 1 shares because both share classes are invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Please note that after-tax returns (shown for Class R4 shares only) reflect the highest individual federal marginal income-tax rate in effect as of the date provided and do not reflect any state or local taxes. Your actual after-tax returns may be different. After-tax returns are not relevant to shares held in an IRA, 401(k), or other tax-advantaged investment plan. After-tax returns for other share classes would vary.&lt;/div&gt;

Please see below a hypothetical example showing the expenses of a $10,000 investment for the time periods indicated and then assuming you sell all of your shares at the end of those periods. The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 28% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests substantially all of its assets in underlying funds using an asset allocation strategy designed for investors expected to retire around the year 2015.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The portfolio managers of the fund allocate assets among the underlying funds according to an asset allocation strategy that becomes increasingly conservative over time. John Hancock Multi-Index 2015 Lifetime Portfolio has a target asset allocation of 45% of its assets in underlying funds that invest primarily in equity securities. The fund will have a greater exposure to underlying funds that invest primarily in fixed-income securities than will a Multi-Index Lifetime Portfolio with a more distant target date. To reduce investment risk and volatility as retirement approaches and in the postretirement years, the asset allocation strategy will change over time according to a predetermined "glide path" shown in the following chart. The fund may be a primary source of income for its shareholders after retirement.&lt;/div&gt;         
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                  GLIDE PATH CHART               
               &lt;/b&gt;&lt;/div&gt;      
 &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;/div&gt;           
                     &lt;img alt="glidepath chart" src="glidepath.jpg"&gt;&lt;/img&gt;   
              
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The allocations reflected in the glide path are referred to as target allocations because they do not reflect active decisions made by the portfolio managers to produce an overweight or an underweight position in a particular asset class. The fund has a target allocation to underlying funds that invest in the broad asset classes of equity and fixed-income securities, but may also allocate its assets to underlying funds that invest outside these asset classes to protect the fund or help it achieve its objective. For example, the fund may also allocate its assets to underlying funds that invest in alternative and specialty asset classes. The managers may change the target allocation without shareholder approval if they believe that such change would benefit the fund and its shareholders. Under normal circumstances, any deviation from the target allocation is not expected to be greater than plus or minus 10%.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Within the prescribed percentage allocation, the managers select the percentage level to be maintained in specific underlying funds. New investments made by the fund may be directed to particular underlying funds in an effort to maintain the desired target allocations. There is no guarantee that the portfolio managers will correctly predict the market or economic conditions and, as with other mutual fund investments, you could lose money even if the fund is at or close to its designated retirement year or in its postretirement stage.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is designed for investors who may remain invested in the fund through their retirement years. The fund will continue to be managed according to an allocation strategy that becomes increasingly conservative over time until approximately twenty years after retirement, at which time the fund expects to maintain a static allocation of approximately 25% of its assets in equity underlying funds.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in underlying funds that invest in a broad range of equity, fixed-income, and alternative/specialty securities and asset classes, including, but not limited to, U.S. and foreign securities, including emerging-market securities, commodities, asset-backed securities, small-cap securities, and below-investment-grade securities (i.e., junk bonds). The underlying funds may also use derivatives, such as swaps, foreign currency forwards, futures, and options, in each case for the purposes of reducing risk, obtaining efficient market exposure and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund will invest in various passively managed underlying funds that as a group hold a wide range of equity-type securities in their portfolios, including convertible securities. The fund may also invest in various actively managed funds. The fund is not designed to track an index or group of indexes. Equity-type securities include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. Certain equity underlying funds may invest in initial public offerings (IPOs). Each of the equity underlying funds has its own investment strategy that, for example, may focus on growth stocks or value stocks, or may employ a strategy combining growth and income stocks, and/or may invest in derivatives such as credit default swaps, foreign currency forwards, interest rate swaps, options on securities, and futures contracts. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from shorter to longer term. The fixed-income underlying funds collectively hold various types of debt instruments such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging market securities). Certain underlying funds may invest in illiquid securities, and certain underlying funds may be non-diversified.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest directly in exchange-traded funds (ETFs), exchange-traded notes (ETNs), the securities of other investment companies, U.S. government securities, and other types of investments such as derivatives, including credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, in each case for the purposes of reducing risk, obtaining efficient market exposure, and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;To the extent permitted by law, the Board of Trustees of the fund may, in its discretion, determine to combine the fund with another fund without shareholder approval if the target allocation of the fund matches the target allocation of the other fund, although there is no assurance that the Board of Trustees will so determine at any point. The fund bears its own expenses and, in addition, indirectly bears its proportionate share of the expenses of the underlying funds in which it invests. The fund's performance reflects both the managers' allocation decisions and the performance of the underlying funds.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Many factors affect performance, and fund shares will fluctuate in price, meaning you could lose money. The fund's investment strategy may not produce the intended results.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;During periods of heightened market volatility or reduced liquidity, governments, their agencies, or other regulatory bodies, both within the United States and abroad, may take steps to intervene. These actions, which could include legislative, regulatory, or economic initiatives, might have unforeseeable consequences and could adversely affect the fund's performance or otherwise constrain the fund's ability to achieve its investment objective.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in fixed-income securities than John Hancock Multi-Index Lifetime Portfolios with target dates that are more distant, fixed-income securities risks are more prevalent in this fund than in these other target-date funds. In addition to fixed-income securities risk, the fund's other main risk factors are listed below in alphabetical order. &lt;i&gt;Before investing, be sure to read the additional descriptions of these risks beginning on page 68 of the prospectus.&lt;/i&gt;            
            &lt;/div&gt;

               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk based on the nature of their support.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;

               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;

               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;

               &lt;b&gt;Target allocation risk.&lt;/b&gt; The fund's risk profile will change due to reallocation or rebalancing of portfolio assets as the fund approaches its target date.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality.

Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide.

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment.

Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;

               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;

               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;

               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;

               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;

               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;

               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's Board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;

               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The following information illustrates the variability of the fund's returns and provides some indication of the risks of investing in the fund by showing changes in the fund's performance from year to year and by showing how the fund's average annual returns compared with a broad-based market index. Past performance (before and after taxes) does not indicate future results. All figures assume dividend reinvestment. Performance information is updated daily, monthly, and quarterly and may be obtained at our website, jhinvestments.com, or by calling 888-972-8696 between 8:30 A.M. and 5:00 P.M., Eastern time, on most business days.&lt;/div&gt;

The information shows how the fund's performance compares with the returns of an index of funds with similar investment objectives. From December 1, 2016 to November 30, 2017, the Custom Benchmark consisted of the following indices and approximate weightings: 33.25% Russell 3000 Index, 14.25% MSCI ACWI ex-USA Index, 42.00% Bloomberg Barclays U.S. Aggregate Bond Index, and 10.50% ICE Bank of America Merrill Lynch U.S. High Yield Master II Index. The weightings of the indices in the Custom Benchmark are adjusted annually to reflect changes in the fund's target asset allocation in accordance with the annual roll-down of the glide path described above and differed in periods prior to December 1, 2016.&lt;/div&gt;

Returns for Class R4 shares between those dates are those of Class 1 shares. Returns for Class R4 shares would have been substantially similar to returns of Class 1 shares because both share classes are invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.&lt;/div&gt;

Your actual after-tax returns may be different. After-tax returns are not relevant to shares held in an IRA, 401(k), or other tax-advantaged investment plan. After-tax returns for other share classes would vary.&lt;/div&gt;

The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 30% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests substantially all of its assets in underlying funds using an asset allocation strategy designed for investors expected to retire around the year 2020.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The portfolio managers of the fund allocate assets among the underlying funds according to an asset allocation strategy that becomes increasingly conservative over time. John Hancock Multi-Index 2020 Lifetime Portfolio has a target asset allocation of 54% of its assets in underlying funds that invest primarily in equity securities. The fund will have a greater exposure to underlying funds that invest primarily in equity securities than will a John Hancock Multi-Index Lifetime Portfolio with a closer target date. To reduce investment risk and volatility as retirement approaches and in the postretirement years, the asset allocation strategy will change over time according to a predetermined "glide path" shown in the following chart. The fund may be a primary source of income for its shareholders after retirement.&lt;/div&gt;         
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                  GLIDE PATH CHART               
               &lt;/b&gt;&lt;/div&gt;  
&lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;/div&gt;            
                     &lt;img alt="glidepath chart" src="glidepath.jpg"&gt;&lt;/img&gt;   
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The allocations reflected in the glide path are referred to as target allocations because they do not reflect active decisions made by the portfolio managers to produce an overweight or an underweight position in a particular asset class. The fund has a target allocation to underlying funds that invest in the broad asset classes of equity and fixed-income securities, but may also allocate its assets to underlying funds that invest outside these asset classes to protect the fund or help it achieve its objective. For example, the fund may also allocate its assets to underlying funds that invest in alternative and specialty asset classes. The managers may change the target allocation without shareholder approval if they believe that such change would benefit the fund and its shareholders. Under normal circumstances, any deviation from the target allocation is not expected to be greater than plus or minus 10%.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Within the prescribed percentage allocation, the managers select the percentage level to be maintained in specific underlying funds. New investments made by the fund may be directed to particular underlying funds in an effort to maintain the desired target allocations. There is no guarantee that the portfolio managers will correctly predict the market or economic conditions and, as with other mutual fund investments, you could lose money even if the fund is at or close to its designated retirement year or in its postretirement stage.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is designed for investors who may remain invested in the fund through their retirement years. The fund will continue to be managed according to an allocation strategy that becomes increasingly conservative over time until approximately twenty years after retirement, at which time the fund expects to maintain a static allocation of approximately 25% of its assets in equity underlying funds.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in underlying funds that invest in a broad range of equity, fixed-income, and alternative/specialty securities and asset classes, including, but not limited to, U.S. and foreign securities, including emerging-market securities, commodities, asset-backed securities, small-cap securities, and below-investment-grade securities (i.e., junk bonds). The underlying funds may also use derivatives, such as swaps, foreign currency forwards, futures, and options, in each case for the purposes of reducing risk, obtaining efficient market exposure and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund will invest in various passively managed underlying funds that as a group hold a wide range of equity-type securities in their portfolios, including convertible securities. The fund may also invest in various actively managed funds. The fund is not designed to track an index or group of indexes. Equity-type securities include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. Certain equity underlying funds may invest in initial public offerings (IPOs). Each of the equity underlying funds has its own investment strategy that, for example, may focus on growth stocks or value stocks, or may employ a strategy combining growth and income stocks, and/or may invest in derivatives such as credit default swaps, foreign currency forwards, interest rate swaps, options on securities, and futures contracts. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from shorter to longer term. The fixed-income underlying funds collectively hold various types of debt instruments such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging market securities). Certain underlying funds may invest in illiquid securities, and certain underlying funds may be non-diversified.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest directly in exchange-traded funds (ETFs), exchange-traded notes (ETNs), the securities of other investment companies, U.S. government securities, and other types of investments such as derivatives, including credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, in each case for the purposes of reducing risk, obtaining efficient market exposure, and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;To the extent permitted by law, the Board of Trustees of the fund may, in its discretion, determine to combine the fund with another fund without shareholder approval if the target allocation of the fund matches the target allocation of the other fund, although there is no assurance that the Board of Trustees will so determine at any point. The fund bears its own expenses and, in addition, indirectly bears its proportionate share of the expenses of the underlying funds in which it invests. The fund's performance reflects both the managers' allocation decisions and the performance of the underlying funds.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Many factors affect performance, and fund shares will fluctuate in price, meaning you could lose money. The fund's investment strategy may not produce the intended results.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;During periods of heightened market volatility or reduced liquidity, governments, their agencies, or other regulatory bodies, both within the United States and abroad, may take steps to intervene. These actions, which could include legislative, regulatory, or economic initiatives, might have unforeseeable consequences and could adversely affect the fund's performance or otherwise constrain the fund's ability to achieve its investment objective.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in equity securities than John Hancock Multi-Index Lifetime Portfolios with closer target dates, equity security risks are more prevalent in this fund than in these other target-date funds. In addition to equity securities risk, the fund's other main risk factors are listed below in alphabetical order. &lt;i&gt;Before investing, be sure to read the additional descriptions of these risks beginning on page 68 of the prospectus.&lt;/i&gt;

               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk based on the nature of their support.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;

               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;

               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;

               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;

               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;

               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;

               &lt;b&gt;Lifecycle risk.&lt;/b&gt; Managers might not correctly predict market or economic conditions, and you could lose money even close to, during, or after the fund's designated retirement year.&lt;/div&gt;

               &lt;b&gt;Target allocation risk.&lt;/b&gt; The fund's risk profile will change due to reallocation or rebalancing of portfolio assets as the fund approaches its target date.&lt;/div&gt;

               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's Board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The following information illustrates the variability of the fund's returns and provides some indication of the risks of investing in the fund by showing changes in the fund's performance from year to year and by showing how the fund's average annual returns compared with a broad-based market index. Past performance (before and after taxes) does not indicate future results. All figures assume dividend reinvestment. Performance information is updated daily, monthly, and quarterly and may be obtained at our website, jhinvestments.com, or by calling 888-972-8696 between 8:30 A.M. and 5:00 P.M., Eastern time, on most business days.&lt;/div&gt;

The information shows how the fund's performance compares with the returns of an index of funds with similar investment objectives. From December 1, 2016 to November 30, 2017, the Custom Benchmark consisted of the following indices and approximate weightings: 40.60% Russell 3000 Index, 17.40% MSCI ACWI ex-USA Index, 33.60% Bloomberg Barclays U.S. Aggregate Bond Index, and 8.40% ICE Bank of America Merrill Lynch U.S. High Yield Master II Index. The weightings of the indices in the Custom Benchmark are adjusted annually to reflect changes in the fund's target asset allocation in accordance with the annual roll-down of the glide path described above and differed in periods prior to December 1, 2016.&lt;/div&gt;

Returns for Class R4 shares between those dates are those of Class 1 shares. Returns for Class R4 shares would have been substantially similar to returns of Class 1 shares because both share classes are invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.&lt;/div&gt;

Your actual after-tax returns may be different. After-tax returns are not relevant to shares held in an IRA, 401(k), or other tax-advantaged investment plan.

The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 23% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests substantially all of its assets in underlying funds using an asset allocation strategy designed for investors expected to retire around the year 2025.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The portfolio managers of the fund allocate assets among the underlying funds according to an asset allocation strategy that becomes increasingly conservative over time. John Hancock Multi-Index 2025 Lifetime Portfolio has a target asset allocation of 65% of its assets in underlying funds that invest primarily in equity securities. The fund will have a greater exposure to underlying funds that invest primarily in equity securities than will a John Hancock Multi-Index Lifetime Portfolio with a closer target date. To reduce investment risk and volatility as retirement approaches and in the postretirement years, the asset allocation strategy will change over time according to a predetermined "glide path" shown in the following chart. The fund may be a primary source of income for its shareholders after retirement.&lt;/div&gt;         
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                  GLIDE PATH CHART               
               &lt;/b&gt;&lt;/div&gt;    
           &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;/div&gt;         
                   &lt;img alt="glidepath chart" src="glidepath.jpg"&gt;&lt;/img&gt;     
        
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The allocations reflected in the glide path are referred to as target allocations because they do not reflect active decisions made by the portfolio managers to produce an overweight or an underweight position in a particular asset class. The fund has a target allocation to underlying funds that invest in the broad asset classes of equity and fixed-income securities, but may also allocate its assets to underlying funds that invest outside these asset classes to protect the fund or help it achieve its objective. For example, the fund may also allocate its assets to underlying funds that invest in alternative and specialty asset classes. The managers may change the target allocation without shareholder approval if they believe that such change would benefit the fund and its shareholders. Under normal circumstances, any deviation from the target allocation is not expected to be greater than plus or minus 10%.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Within the prescribed percentage allocation, the managers select the percentage level to be maintained in specific underlying funds. New investments made by the fund may be directed to particular underlying funds in an effort to maintain the desired target allocations. There is no guarantee that the portfolio managers will correctly predict the market or economic conditions and, as with other mutual fund investments, you could lose money even if the fund is at or close to its designated retirement year or in its postretirement stage.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is designed for investors who may remain invested in the fund through their retirement years. The fund will continue to be managed according to an allocation strategy that becomes increasingly conservative over time until approximately twenty years after retirement, at which time the fund expects to maintain a static allocation of approximately 25% of its assets in equity underlying funds.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in underlying funds that invest in a broad range of equity, fixed-income, and alternative/specialty securities and asset classes, including, but not limited to, U.S. and foreign securities, including emerging-market securities, commodities, asset-backed securities, small-cap securities, and below-investment-grade securities (i.e., junk bonds). The underlying funds may also use derivatives, such as swaps, foreign currency forwards, futures, and options, in each case for the purposes of reducing risk, obtaining efficient market exposure and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund will invest in various passively managed underlying funds that as a group hold a wide range of equity-type securities in their portfolios, including convertible securities. The fund may also invest in various actively managed funds. The fund is not designed to track an index or group of indexes. Equity-type securities include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. Certain equity underlying funds may invest in initial public offerings (IPOs). Each of the equity underlying funds has its own investment strategy that, for example, may focus on growth stocks or value stocks, or may employ a strategy combining growth and income stocks, and/or may invest in derivatives such as credit default swaps, foreign currency forwards, interest rate swaps, options on securities, and futures contracts. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from shorter to longer term. The fixed-income underlying funds collectively hold various types of debt instruments such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging market securities). Certain underlying funds may invest in illiquid securities, and certain underlying funds may be non-diversified.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest directly in exchange-traded funds (ETFs), exchange-traded notes (ETNs), the securities of other investment companies, U.S. government securities, and other types of investments such as derivatives, including credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, in each case for the purposes of reducing risk, obtaining efficient market exposure, and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;To the extent permitted by law, the Board of Trustees of the fund may, in its discretion, determine to combine the fund with another fund without shareholder approval if the target allocation of the fund matches the target allocation of the other fund, although there is no assurance that the Board of Trustees will so determine at any point. The fund bears its own expenses and, in addition, indirectly bears its proportionate share of the expenses of the underlying funds in which it invests. The fund's performance reflects both the managers' allocation decisions and the performance of the underlying funds.&lt;/div&gt;

Many factors affect performance, and fund shares will fluctuate in price, meaning you could lose money. The fund's investment strategy may not produce the intended results.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;During periods of heightened market volatility or reduced liquidity, governments, their agencies, or other regulatory bodies, both within the United States and abroad, may take steps to intervene. These actions, which could include legislative, regulatory, or economic initiatives, might have unforeseeable consequences and could adversely affect the fund's performance or otherwise constrain the fund's ability to achieve its investment objective.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in equity securities than John Hancock Multi-Index Lifetime Portfolios with closer target dates, equity security risks are more prevalent in this fund than in these other target-date funds. In addition to equity securities risk, the fund's other main risk factors are listed below in alphabetical order. &lt;i&gt;Before investing, be sure to read the additional descriptions of these risks beginning on page 68 of the prospectus.&lt;/i&gt;            
            &lt;/div&gt;

               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk based on the nature of their support.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;

               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;

               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;

               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Investment company securities risk.&lt;/b&gt; A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;

               &lt;b&gt;Lifecycle risk.&lt;/b&gt; Managers might not correctly predict market or economic conditions, and you could lose money even close to, during, or after the fund's designated retirement year.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Target allocation risk.&lt;/b&gt; The fund's risk profile will change due to reallocation or rebalancing of portfolio assets as the fund approaches its target date.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's Board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

From December 1, 2016 to November 30, 2017, the Custom Benchmark consisted of the following indices and approximate weightings: 49.00% Russell 3000 Index, 21.00% MSCI ACWI ex-USA Index, 24.00% Bloomberg Barclays U.S. Aggregate Bond Index, and 6.00% ICE Bank of America Merrill Lynch U.S. High Yield Master II Index. The weightings of the indices in the Custom Benchmark are adjusted annually to reflect changes in the fund's target asset allocation in accordance with the annual roll-down of the glide path described above and differed in periods prior to December 1, 2016.&lt;/div&gt;

Returns for Class R4 shares between those dates are those of Class 1 shares. Returns for Class R4 shares would have been substantially similar to returns of Class 1 shares because both share classes are invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Please note that after-tax returns (shown for Class R4 shares only) reflect the highest individual federal marginal income-tax rate in effect as of the date provided and do not reflect any state or local taxes. Your actual after-tax returns may be different. After-tax returns are not relevant to shares held in an IRA, 401(k), or other tax-advantaged investment plan. After-tax returns for other share classes would vary.&lt;/div&gt;

The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 19% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests substantially all of its assets in underlying funds using an asset allocation strategy designed for investors expected to retire around the year 2030.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The portfolio managers of the fund allocate assets among the underlying funds according to an asset allocation strategy that becomes increasingly conservative over time. John Hancock Multi-Index 2030 Lifetime Portfolio has a target asset allocation of 77% of its assets in underlying funds that invest primarily in equity securities. The fund will have a greater exposure to underlying funds that invest primarily in equity securities than will a John Hancock Multi-Index Lifetime Portfolio with a closer target date. To reduce investment risk and volatility as retirement approaches and in the postretirement years, the asset allocation strategy will change over time according to a predetermined "glide path" shown in the following chart. The fund may be a primary source of income for its shareholders after retirement.&lt;/div&gt;         
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                  GLIDE PATH CHART               
               &lt;/b&gt;&lt;/div&gt;             
                &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;/div&gt;        
                  &lt;img alt="glidepath chart" src="glidepath.jpg"&gt;&lt;/img&gt;   
                   
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The allocations reflected in the glide path are referred to as target allocations because they do not reflect active decisions made by the portfolio managers to produce an overweight or an underweight position in a particular asset class. The fund has a target allocation to underlying funds that invest in the broad asset classes of equity and fixed-income securities, but may also allocate its assets to underlying funds that invest outside these asset classes to protect the fund or help it achieve its objective. For example, the fund may also allocate its assets to underlying funds that invest in alternative and specialty asset classes. The managers may change the target allocation without shareholder approval if they believe that such change would benefit the fund and its shareholders. Under normal circumstances, any deviation from the target allocation is not expected to be greater than plus or minus 10%.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Within the prescribed percentage allocation, the managers select the percentage level to be maintained in specific underlying funds. New investments made by the fund may be directed to particular underlying funds in an effort to maintain the desired target allocations. There is no guarantee that the portfolio managers will correctly predict the market or economic conditions and, as with other mutual fund investments, you could lose money even if the fund is at or close to its designated retirement year or in its postretirement stage.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is designed for investors who may remain invested in the fund through their retirement years. The fund will continue to be managed according to an allocation strategy that becomes increasingly conservative over time until approximately twenty years after retirement, at which time the fund expects to maintain a static allocation of approximately 25% of its assets in equity underlying funds.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in underlying funds that invest in a broad range of equity, fixed-income, and alternative/specialty securities and asset classes, including, but not limited to, U.S. and foreign securities, including emerging-market securities, commodities, asset-backed securities, small-cap securities, and below-investment-grade securities (i.e., junk bonds). The underlying funds may also use derivatives, such as swaps, foreign currency forwards, futures, and options, in each case for the purposes of reducing risk, obtaining efficient market exposure and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund will invest in various passively managed underlying funds that as a group hold a wide range of equity-type securities in their portfolios, including convertible securities. The fund may also invest in various actively managed funds. The fund is not designed to track an index or group of indexes. Equity-type securities include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. Certain equity underlying funds may invest in initial public offerings (IPOs). Each of the equity underlying funds has its own investment strategy that, for example, may focus on growth stocks or value stocks, or may employ a strategy combining growth and income stocks, and/or may invest in derivatives such as credit default swaps, foreign currency forwards, interest rate swaps, options on securities, and futures contracts. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from shorter to longer term. The fixed-income underlying funds collectively hold various types of debt instruments such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging market securities). Certain underlying funds may invest in illiquid securities, and certain underlying funds may be non-diversified.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest directly in exchange-traded funds (ETFs), exchange-traded notes (ETNs), the securities of other investment companies, U.S. government securities, and other types of investments such as derivatives, including credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, in each case for the purposes of reducing risk, obtaining efficient market exposure, and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;To the extent permitted by law, the Board of Trustees of the fund may, in its discretion, determine to combine the fund with another fund without shareholder approval if the target allocation of the fund matches the target allocation of the other fund, although there is no assurance that the Board of Trustees will so determine at any point. The fund bears its own expenses and, in addition, indirectly bears its proportionate share of the expenses of the underlying funds in which it invests. The fund's performance reflects both the managers' allocation decisions and the performance of the underlying funds.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Many factors affect performance, and fund shares will fluctuate in price, meaning you could lose money. The fund's investment strategy may not produce the intended results.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;During periods of heightened market volatility or reduced liquidity, governments, their agencies, or other regulatory bodies, both within the United States and abroad, may take steps to intervene. These actions, which could include legislative, regulatory, or economic initiatives, might have unforeseeable consequences and could adversely affect the fund's performance or otherwise constrain the fund's ability to achieve its investment objective.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in equity securities than John Hancock Multi-Index Lifetime Portfolios with closer target dates, equity security risks are more prevalent in this fund than in these other target-date funds. In addition to equity securities risk, the fund's other main risk factors are listed below in alphabetical order. &lt;i&gt;Before investing, be sure to read the additional descriptions of these risks beginning on page 68 of the prospectus.&lt;/i&gt;            
            &lt;/div&gt;

               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk based on the nature of their support.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;

               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;

               &lt;b&gt;Target allocation risk.&lt;/b&gt; The fund's risk profile will change due to reallocation or rebalancing of portfolio assets as the fund approaches its target date.&lt;/div&gt;

               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;

Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment.

Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;

               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;

               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;

               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;

               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;

               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;

               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;

               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;

               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's Board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;

               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;

               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The following information illustrates the variability of the fund's returns and provides some indication of the risks of investing in the fund by showing changes in the fund's performance from year to year and by showing how the fund's average annual returns compared with a broad-based market index. Past performance (before and after taxes) does not indicate future results. All figures assume dividend reinvestment. Performance information is updated daily, monthly, and quarterly and may be obtained at our website, jhinvestments.com, or by calling 888-972-8696 between 8:30 A.M. and 5:00 P.M., Eastern time, on most business days.&lt;/div&gt;

The information shows how the fund's performance compares with the returns of an index of funds with similar investment objectives. From December 1, 2016 to November 30, 2017, the Custom Benchmark consisted of the following indices and approximate weightings: 56.70% Russell 3000 Index, 24.30% MSCI ACWI ex-USA Index, 15.20% Bloomberg Barclays U.S. Aggregate Bond Index, and 3.80% ICE Bank of America Merrill Lynch U.S. High Yield Master II Index. The weightings of the indices in the Custom Benchmark are adjusted annually to reflect changes in the fund's target asset allocation in accordance with the annual roll-down of the glide path described above and differed in periods prior to December 1, 2016.&lt;/div&gt;

Returns for Class R4 shares between those dates are those of Class 1 shares. Returns for Class R4 shares would have been substantially similar to returns of Class 1 shares because both share classes are invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.&lt;/div&gt;

Your actual after-tax returns may be different. After-tax returns are not relevant to shares held in an IRA, 401(k), or other tax-advantaged investment plan. After-tax returns for other share classes would vary.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 15% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests substantially all of its assets in underlying funds using an asset allocation strategy designed for investors expected to retire around the year 2035.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The portfolio managers of the fund allocate assets among the underlying funds according to an asset allocation strategy that becomes increasingly conservative over time. John Hancock Multi-Index 2035 Lifetime Portfolio has a target asset allocation of 86% of its assets in underlying funds that invest primarily in equity securities. The fund will have a greater exposure to underlying funds that invest primarily in equity securities than will a John Hancock Multi-Index Lifetime Portfolio with a closer target date. To reduce investment risk and volatility as retirement approaches and in the postretirement years, the asset allocation strategy will change over time according to a predetermined "glide path" shown in the following chart. The fund may be a primary source of income for its shareholders after retirement.&lt;/div&gt;         
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                  GLIDE PATH CHART               
               &lt;/b&gt;&lt;/div&gt;  
     &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;/div&gt;             
                   &lt;img alt="glidepath chart" src="glidepath.jpg"&gt;&lt;/img&gt;     
                  
               
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The allocations reflected in the glide path are referred to as target allocations because they do not reflect active decisions made by the portfolio managers to produce an overweight or an underweight position in a particular asset class. The fund has a target allocation to underlying funds that invest in the broad asset classes of equity and fixed-income securities, but may also allocate its assets to underlying funds that invest outside these asset classes to protect the fund or help it achieve its objective. For example, the fund may also allocate its assets to underlying funds that invest in alternative and specialty asset classes. The managers may change the target allocation without shareholder approval if they believe that such change would benefit the fund and its shareholders. Under normal circumstances, any deviation from the target allocation is not expected to be greater than plus or minus 10%.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Within the prescribed percentage allocation, the managers select the percentage level to be maintained in specific underlying funds. New investments made by the fund may be directed to particular underlying funds in an effort to maintain the desired target allocations. There is no guarantee that the portfolio managers will correctly predict the market or economic conditions and, as with other mutual fund investments, you could lose money even if the fund is at or close to its designated retirement year or in its postretirement stage.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is designed for investors who may remain invested in the fund through their retirement years. The fund will continue to be managed according to an allocation strategy that becomes increasingly conservative over time until approximately twenty years after retirement, at which time the fund expects to maintain a static allocation of approximately 25% of its assets in equity underlying funds.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in underlying funds that invest in a broad range of equity, fixed-income, and alternative/specialty securities and asset classes, including, but not limited to, U.S. and foreign securities, including emerging-market securities, commodities, asset-backed securities, small-cap securities, and below-investment-grade securities (i.e., junk bonds). The underlying funds may also use derivatives, such as swaps, foreign currency forwards, futures, and options, in each case for the purposes of reducing risk, obtaining efficient market exposure and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund will invest in various passively managed underlying funds that as a group hold a wide range of equity-type securities in their portfolios, including convertible securities. The fund may also invest in various actively managed funds. The fund is not designed to track an index or group of indexes. Equity-type securities include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. Certain equity underlying funds may invest in initial public offerings (IPOs). Each of the equity underlying funds has its own investment strategy that, for example, may focus on growth stocks or value stocks, or may employ a strategy combining growth and income stocks, and/or may invest in derivatives such as credit default swaps, foreign currency forwards, interest rate swaps, options on securities, and futures contracts. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from shorter to longer term. The fixed-income underlying funds collectively hold various types of debt instruments such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging market securities). Certain underlying funds may invest in illiquid securities, and certain underlying funds may be non-diversified.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest directly in exchange-traded funds (ETFs), exchange-traded notes (ETNs), the securities of other investment companies, U.S. government securities, and other types of investments such as derivatives, including credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, in each case for the purposes of reducing risk, obtaining efficient market exposure, and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;To the extent permitted by law, the Board of Trustees of the fund may, in its discretion, determine to combine the fund with another fund without shareholder approval if the target allocation of the fund matches the target allocation of the other fund, although there is no assurance that the Board of Trustees will so determine at any point. The fund bears its own expenses and, in addition, indirectly bears its proportionate share of the expenses of the underlying funds in which it invests. The fund's performance reflects both the managers' allocation decisions and the performance of the underlying funds.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Many factors affect performance, and fund shares will fluctuate in price, meaning you could lose money. The fund's investment strategy may not produce the intended results.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;During periods of heightened market volatility or reduced liquidity, governments, their agencies, or other regulatory bodies, both within the United States and abroad, may take steps to intervene. These actions, which could include legislative, regulatory, or economic initiatives, might have unforeseeable consequences and could adversely affect the fund's performance or otherwise constrain the fund's ability to achieve its investment objective.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in equity securities than John Hancock Multi-Index Lifetime Portfolios with closer target dates, equity security risks are more prevalent in this fund than in these other target-date funds. In addition to equity securities risk, the fund's other main risk factors are listed below in alphabetical order. &lt;i&gt;Before investing, be sure to read the additional descriptions of these risks beginning on page 68 of the prospectus.&lt;/i&gt;

               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk based on the nature of their support.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;

               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;

               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;

               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;

               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;

               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;

               &lt;b&gt;Lifecycle risk.&lt;/b&gt; Managers might not correctly predict market or economic conditions, and you could lose money even close to, during, or after the fund's designated retirement year.&lt;/div&gt;

               &lt;b&gt;Target allocation risk.&lt;/b&gt; The fund's risk profile will change due to reallocation or rebalancing of portfolio assets as the fund approaches its target date.&lt;/div&gt;

               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's Board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The following information illustrates the variability of the fund's returns and provides some indication of the risks of investing in the fund by showing changes in the fund's performance from year to year and by showing how the fund's average annual returns compared with a broad-based market index. Past performance (before and after taxes) does not indicate future results. All figures assume dividend reinvestment. Performance information is updated daily, monthly, and quarterly and may be obtained at our website, jhinvestments.com, or by calling 888-972-8696 between 8:30 A.M. and 5:00 P.M., Eastern time, on most business days.&lt;/div&gt;

The information shows how the fund's performance compares with the returns of an index of funds with similar investment objectives. From December 1, 2016 to November 30, 2017, the Custom Benchmark consisted of the following indices and approximate weightings: 62.30% Russell 3000 Index, 26.70% MSCI ACWI ex-USA Index, 8.80% Bloomberg Barclays U.S. Aggregate Bond Index, and 2.20% ICE Bank of America Merrill Lynch U.S. High Yield Master II Index. The weightings of the indices in the Custom Benchmark are adjusted annually to reflect changes in the fund's target asset allocation in accordance with the annual roll-down of the glide path described above and differed in periods prior to December 1, 2016.&lt;/div&gt;

Returns for Class R4 shares between those dates are those of Class 1 shares. Returns for Class R4 shares would have been substantially similar to returns of Class 1 shares because both share classes are invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.&lt;/div&gt;

Your actual after-tax returns may be different. After-tax returns are not relevant to shares held in an IRA, 401(k), or other tax-advantaged investment plan.

The example assumes a 5% average annual return and that fund expenses will not change over the periods.

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 15% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests substantially all of its assets in underlying funds using an asset allocation strategy designed for investors expected to retire around the year 2040.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The portfolio managers of the fund allocate assets among the underlying funds according to an asset allocation strategy that becomes increasingly conservative over time. John Hancock Multi-Index 2040 Lifetime Portfolio has a target asset allocation of 93% of its assets in underlying funds that invest primarily in equity securities. The fund will have a greater exposure to underlying funds that invest primarily in equity securities than will a John Hancock Multi-Index Lifetime Portfolio with a closer target date. To reduce investment risk and volatility as retirement approaches and in the postretirement years, the asset allocation strategy will change over time according to a predetermined "glide path" shown in the following chart. The fund may be a primary source of income for its shareholders after retirement.&lt;/div&gt;         
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                  GLIDE PATH CHART               
               &lt;/b&gt;&lt;/div&gt;     
    &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;/div&gt;        
                   &lt;img alt="glidepath chart" src="glidepath.jpg"&gt;&lt;/img&gt;     
                  
                  
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The allocations reflected in the glide path are referred to as target allocations because they do not reflect active decisions made by the portfolio managers to produce an overweight or an underweight position in a particular asset class. The fund has a target allocation to underlying funds that invest in the broad asset classes of equity and fixed-income securities, but may also allocate its assets to underlying funds that invest outside these asset classes to protect the fund or help it achieve its objective. For example, the fund may also allocate its assets to underlying funds that invest in alternative and specialty asset classes. The managers may change the target allocation without shareholder approval if they believe that such change would benefit the fund and its shareholders. Under normal circumstances, any deviation from the target allocation is not expected to be greater than plus or minus 10%.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Within the prescribed percentage allocation, the managers select the percentage level to be maintained in specific underlying funds. New investments made by the fund may be directed to particular underlying funds in an effort to maintain the desired target allocations. There is no guarantee that the portfolio managers will correctly predict the market or economic conditions and, as with other mutual fund investments, you could lose money even if the fund is at or close to its designated retirement year or in its postretirement stage.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is designed for investors who may remain invested in the fund through their retirement years. The fund will continue to be managed according to an allocation strategy that becomes increasingly conservative over time until approximately twenty years after retirement, at which time the fund expects to maintain a static allocation of approximately 25% of its assets in equity underlying funds.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in underlying funds that invest in a broad range of equity, fixed-income, and alternative/specialty securities and asset classes, including, but not limited to, U.S. and foreign securities, including emerging-market securities, commodities, asset-backed securities, small-cap securities, and below-investment-grade securities (i.e., junk bonds). The underlying funds may also use derivatives, such as swaps, foreign currency forwards, futures, and options, in each case for the purposes of reducing risk, obtaining efficient market exposure and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund will invest in various passively managed underlying funds that as a group hold a wide range of equity-type securities in their portfolios, including convertible securities. The fund may also invest in various actively managed funds. The fund is not designed to track an index or group of indexes. Equity-type securities include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. Certain equity underlying funds may invest in initial public offerings (IPOs). Each of the equity underlying funds has its own investment strategy that, for example, may focus on growth stocks or value stocks, or may employ a strategy combining growth and income stocks, and/or may invest in derivatives such as credit default swaps, foreign currency forwards, interest rate swaps, options on securities, and futures contracts. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from shorter to longer term. The fixed-income underlying funds collectively hold various types of debt instruments such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging market securities). Certain underlying funds may invest in illiquid securities, and certain underlying funds may be non-diversified.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest directly in exchange-traded funds (ETFs), exchange-traded notes (ETNs), the securities of other investment companies, U.S. government securities, and other types of investments such as derivatives, including credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, in each case for the purposes of reducing risk, obtaining efficient market exposure, and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;To the extent permitted by law, the Board of Trustees of the fund may, in its discretion, determine to combine the fund with another fund without shareholder approval if the target allocation of the fund matches the target allocation of the other fund, although there is no assurance that the Board of Trustees will so determine at any point. The fund bears its own expenses and, in addition, indirectly bears its proportionate share of the expenses of the underlying funds in which it invests. The fund's performance reflects both the managers' allocation decisions and the performance of the underlying funds.&lt;/div&gt;

Many factors affect performance, and fund shares will fluctuate in price, meaning you could lose money. The fund's investment strategy may not produce the intended results.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;During periods of heightened market volatility or reduced liquidity, governments, their agencies, or other regulatory bodies, both within the United States and abroad, may take steps to intervene. These actions, which could include legislative, regulatory, or economic initiatives, might have unforeseeable consequences and could adversely affect the fund's performance or otherwise constrain the fund's ability to achieve its investment objective.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in equity securities than John Hancock Multi-Index Lifetime Portfolios with closer target dates, equity security risks are more prevalent in this fund than in these other target-date funds. In addition to equity securities risk, the fund's other main risk factors are listed below in alphabetical order. &lt;i&gt;Before investing, be sure to read the additional descriptions of these risks beginning on page 68 of the prospectus.&lt;/i&gt;            
            &lt;/div&gt;

                &lt;i&gt;  Principal risks of investing in the fund of funds&lt;/i&gt;               
               &lt;/b&gt;&lt;/div&gt;

               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk based on the nature of their support.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;

               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;

               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Investment company securities risk.&lt;/b&gt; A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;

               &lt;b&gt;Lifecycle risk.&lt;/b&gt; Managers might not correctly predict market or economic conditions, and you could lose money even close to, during, or after the fund's designated retirement year.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Target allocation risk.&lt;/b&gt; The fund's risk profile will change due to reallocation or rebalancing of portfolio assets as the fund approaches its target date.&lt;/div&gt;

                &lt;i&gt;  Principal risks of investing in the underlying funds  &lt;/i&gt;             
               &lt;/b&gt;&lt;/div&gt;             
                     
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's Board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

From November 7, 2013 to November 30, 2017, the Custom Benchmark consisted of the following indices and approximate weightings: 66.50% Russell 3000 Index, 28.50% MSCI ACWI ex-USA Index, 4.00% Bloomberg Barclays U.S. Aggregate Bond Index, and 1.00% ICE Bank of America Merrill Lynch U.S. High Yield Master II Index. The weightings of the indices in the Custom Benchmark are adjusted annually to reflect changes in the fund's target asset allocation in accordance with the annual roll-down of the glide path described above.&lt;/div&gt;

Returns for Class R4 shares between those dates are those of Class 1 shares. Returns for Class R4 shares would have been substantially similar to returns of Class 1 shares because both share classes are invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.&lt;/div&gt;

Your actual after-tax returns may be different. After-tax returns are not relevant to shares held in an IRA, 401(k), or other tax-advantaged investment plan. After-tax returns for other share classes would vary.&lt;/div&gt;

Please see below a hypothetical example showing the expenses of a $10,000 investment for the time periods indicated and then assuming you sell all of your shares at the end of those periods. The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 12% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests substantially all of its assets in underlying funds using an asset allocation strategy designed for investors expected to retire around the year 2045.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The portfolio managers of the fund allocate assets among the underlying funds according to an asset allocation strategy that becomes increasingly conservative over time. John Hancock Multi-Index 2045 Lifetime Portfolio has a target asset allocation of 95% of its assets in underlying funds that invest primarily in equity securities. The fund will have a greater exposure to underlying funds that invest primarily in equity securities than will a John Hancock Multi-Index Lifetime Portfolio with a closer target date. To reduce investment risk and volatility as retirement approaches and in the postretirement years, the asset allocation strategy will change over time according to a predetermined "glide path" shown in the following chart. The fund may be a primary source of income for its shareholders after retirement.&lt;/div&gt;          
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                  GLIDE PATH CHART               
               &lt;/b&gt;&lt;/div&gt;             
                   &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;/div&gt;   
                  &lt;img alt="glidepath chart" src="glidepath.jpg"&gt;&lt;/img&gt;   
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The allocations reflected in the glide path are referred to as target allocations because they do not reflect active decisions made by the portfolio managers to produce an overweight or an underweight position in a particular asset class. The fund has a target allocation to underlying funds that invest in the broad asset classes of equity and fixed-income securities, but may also allocate its assets to underlying funds that invest outside these asset classes to protect the fund or help it achieve its objective. For example, the fund may also allocate its assets to underlying funds that invest in alternative and specialty asset classes. The managers may change the target allocation without shareholder approval if they believe that such change would benefit the fund and its shareholders. Under normal circumstances, any deviation from the target allocation is not expected to be greater than plus or minus 10%.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Within the prescribed percentage allocation, the managers select the percentage level to be maintained in specific underlying funds. New investments made by the fund may be directed to particular underlying funds in an effort to maintain the desired target allocations. There is no guarantee that the portfolio managers will correctly predict the market or economic conditions and, as with other mutual fund investments, you could lose money even if the fund is at or close to its designated retirement year or in its postretirement stage.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is designed for investors who may remain invested in the fund through their retirement years. The fund will continue to be managed according to an allocation strategy that becomes increasingly conservative over time until approximately twenty years after retirement, at which time the fund expects to maintain a static allocation of approximately 25% of its assets in equity underlying funds.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in underlying funds that invest in a broad range of equity, fixed-income, and alternative/specialty securities and asset classes, including, but not limited to, U.S. and foreign securities, including emerging-market securities, commodities, asset-backed securities, small-cap securities, and below-investment-grade securities (i.e., junk bonds). The underlying funds may also use derivatives, such as swaps, foreign currency forwards, futures, and options, in each case for the purposes of reducing risk, obtaining efficient market exposure and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund will invest in various passively managed underlying funds that as a group hold a wide range of equity-type securities in their portfolios, including convertible securities. The fund may also invest in various actively managed funds. The fund is not designed to track an index or group of indexes. Equity-type securities include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. Certain equity underlying funds may invest in initial public offerings (IPOs). Each of the equity underlying funds has its own investment strategy that, for example, may focus on growth stocks or value stocks, or may employ a strategy combining growth and income stocks, and/or may invest in derivatives such as credit default swaps, foreign currency forwards, interest rate swaps, options on securities, and futures contracts. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from shorter to longer term. The fixed-income underlying funds collectively hold various types of debt instruments such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging market securities). Certain underlying funds may invest in illiquid securities, and certain underlying funds may be non-diversified.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest directly in exchange-traded funds (ETFs), exchange-traded notes (ETNs), the securities of other investment companies, U.S. government securities, and other types of investments such as derivatives, including credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, in each case for the purposes of reducing risk, obtaining efficient market exposure, and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;To the extent permitted by law, the Board of Trustees of the fund may, in its discretion, determine to combine the fund with another fund without shareholder approval if the target allocation of the fund matches the target allocation of the other fund, although there is no assurance that the Board of Trustees will so determine at any point. The fund bears its own expenses and, in addition, indirectly bears its proportionate share of the expenses of the underlying funds in which it invests. The fund's performance reflects both the managers' allocation decisions and the performance of the underlying funds.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Many factors affect performance, and fund shares will fluctuate in price, meaning you could lose money. The fund's investment strategy may not produce the intended results.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;During periods of heightened market volatility or reduced liquidity, governments, their agencies, or other regulatory bodies, both within the United States and abroad, may take steps to intervene. These actions, which could include legislative, regulatory, or economic initiatives, might have unforeseeable consequences and could adversely affect the fund's performance or otherwise constrain the fund's ability to achieve its investment objective.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in equity securities than John Hancock Multi-Index Lifetime Portfolios with closer target dates, equity security risks are more prevalent in this fund than in these other target-date funds. In addition to equity securities risk, the fund's other main risk factors are listed below in alphabetical order. &lt;i&gt;Before investing, be sure to read the additional descriptions of these risks beginning on page 68 of the prospectus.&lt;/i&gt;            
            &lt;/div&gt;

               &lt;/b&gt;&lt;/div&gt;

               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk based on the nature of their support.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;

               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;

               &lt;b&gt;Lifecycle risk.&lt;/b&gt; Managers might not correctly predict market or economic conditions, and you could lose money even close to, during, or after the fund's designated retirement year.&lt;/div&gt;

               &lt;b&gt;Target allocation risk.&lt;/b&gt; The fund's risk profile will change due to reallocation or rebalancing of portfolio assets as the fund approaches its target date.&lt;/div&gt;

                  &lt;i&gt;Principal risks of investing in the underlying funds   &lt;/i&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;

Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;

               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;

               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;

               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;

               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;

               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;

               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;

               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;

               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's Board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;

               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The following information illustrates the variability of the fund's returns and provides some indication of the risks of investing in the fund by showing changes in the fund's performance from year to year and by showing how the fund's average annual returns compared with a broad-based market index. Past performance (before and after taxes) does not indicate future results. All figures assume dividend reinvestment. Performance information is updated daily, monthly, and quarterly and may be obtained at our website, jhinvestments.com, or by calling 888-972-8696 between 8:30 A.M. and 5:00 P.M., Eastern time, on most business days.&lt;/div&gt;

The information shows how the fund's performance compares with the returns of an index of funds with similar investment objectives. From November 7, 2013 to November 30, 2017, the Custom Benchmark consisted of the following indices and approximate weightings: 66.50% Russell 3000 Index, 28.50% MSCI ACWI ex-USA Index, 4.00% Bloomberg Barclays U.S. Aggregate Bond Index, and 1.00% ICE Bank of America Merrill Lynch U.S. High Yield Master II Index. The weightings of the indices in the Custom Benchmark are adjusted annually to reflect changes in the fund's target asset allocation in accordance with the annual roll-down of the glide path described above.&lt;/div&gt;

Returns for Class R4 shares between those dates are those of Class 1 shares. Returns for Class R4 shares would have been substantially similar to returns of Class 1 shares because both share classes are invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.&lt;/div&gt;

Your actual after-tax returns may be different. After-tax returns are not relevant to shares held in an IRA, 401(k), or other tax-advantaged investment plan. After-tax returns for other share classes would vary.&lt;/div&gt;

The example assumes a 5% average annual return and that fund expenses will not change over the periods.

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 14% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests substantially all of its assets in underlying funds using an asset allocation strategy designed for investors expected to retire around the year 2050.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The portfolio managers of the fund allocate assets among the underlying funds according to an asset allocation strategy that becomes increasingly conservative over time. John Hancock Multi-Index 2050 Lifetime Portfolio has a target asset allocation of 95% of its assets in underlying funds that invest primarily in equity securities. The fund will have a greater exposure to underlying funds that invest primarily in equity securities than will a John Hancock Multi-Index Lifetime Portfolio with a closer target date. To reduce investment risk and volatility as retirement approaches and in the postretirement years, the asset allocation strategy will change over time according to a predetermined "glide path" shown in the following chart. The fund may be a primary source of income for its shareholders after retirement.&lt;/div&gt;          
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                  GLIDE PATH CHART               
               &lt;/b&gt;&lt;/div&gt; 
&lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;/div&gt;             
                  &lt;img alt="glidepath chart" src="glidepath.jpg"&gt;&lt;/img&gt;      
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The allocations reflected in the glide path are referred to as target allocations because they do not reflect active decisions made by the portfolio managers to produce an overweight or an underweight position in a particular asset class. The fund has a target allocation to underlying funds that invest in the broad asset classes of equity and fixed-income securities, but may also allocate its assets to underlying funds that invest outside these asset classes to protect the fund or help it achieve its objective. For example, the fund may also allocate its assets to underlying funds that invest in alternative and specialty asset classes. The managers may change the target allocation without shareholder approval if they believe that such change would benefit the fund and its shareholders. Under normal circumstances, any deviation from the target allocation is not expected to be greater than plus or minus 10%.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Within the prescribed percentage allocation, the managers select the percentage level to be maintained in specific underlying funds. New investments made by the fund may be directed to particular underlying funds in an effort to maintain the desired target allocations. There is no guarantee that the portfolio managers will correctly predict the market or economic conditions and, as with other mutual fund investments, you could lose money even if the fund is at or close to its designated retirement year or in its postretirement stage.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is designed for investors who may remain invested in the fund through their retirement years. The fund will continue to be managed according to an allocation strategy that becomes increasingly conservative over time until approximately twenty years after retirement, at which time the fund expects to maintain a static allocation of approximately 25% of its assets in equity underlying funds.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in underlying funds that invest in a broad range of equity, fixed-income, and alternative/specialty securities and asset classes, including, but not limited to, U.S. and foreign securities, including emerging-market securities, commodities, asset-backed securities, small-cap securities, and below-investment-grade securities (i.e., junk bonds). The underlying funds may also use derivatives, such as swaps, foreign currency forwards, futures, and options, in each case for the purposes of reducing risk, obtaining efficient market exposure and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund will invest in various passively managed underlying funds that as a group hold a wide range of equity-type securities in their portfolios, including convertible securities. The fund may also invest in various actively managed funds. The fund is not designed to track an index or group of indexes. Equity-type securities include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. Certain equity underlying funds may invest in initial public offerings (IPOs). Each of the equity underlying funds has its own investment strategy that, for example, may focus on growth stocks or value stocks, or may employ a strategy combining growth and income stocks, and/or may invest in derivatives such as credit default swaps, foreign currency forwards, interest rate swaps, options on securities, and futures contracts. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from shorter to longer term. The fixed-income underlying funds collectively hold various types of debt instruments such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging market securities). Certain underlying funds may invest in illiquid securities, and certain underlying funds may be non-diversified.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest directly in exchange-traded funds (ETFs), exchange-traded notes (ETNs), the securities of other investment companies, U.S. government securities, and other types of investments such as derivatives, including credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, in each case for the purposes of reducing risk, obtaining efficient market exposure, and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;To the extent permitted by law, the Board of Trustees of the fund may, in its discretion, determine to combine the fund with another fund without shareholder approval if the target allocation of the fund matches the target allocation of the other fund, although there is no assurance that the Board of Trustees will so determine at any point. The fund bears its own expenses and, in addition, indirectly bears its proportionate share of the expenses of the underlying funds in which it invests. The fund's performance reflects both the managers' allocation decisions and the performance of the underlying funds.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Many factors affect performance, and fund shares will fluctuate in price, meaning you could lose money. The fund's investment strategy may not produce the intended results.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;During periods of heightened market volatility or reduced liquidity, governments, their agencies, or other regulatory bodies, both within the United States and abroad, may take steps to intervene. These actions, which could include legislative, regulatory, or economic initiatives, might have unforeseeable consequences and could adversely affect the fund's performance or otherwise constrain the fund's ability to achieve its investment objective.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in equity securities than John Hancock Multi-Index Lifetime Portfolios with closer target dates, equity security risks are more prevalent in this fund than in these other target-date funds. In addition to equity securities risk, the fund's other main risk factors are listed below in alphabetical order. &lt;i&gt;Before investing, be sure to read the additional descriptions of these risks beginning on page 68 of the prospectus.&lt;/i&gt;

               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk based on the nature of their support.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;

               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;

               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;

               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;

               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;

               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;

               &lt;b&gt;Target allocation risk.&lt;/b&gt; The fund's risk profile will change due to reallocation or rebalancing of portfolio assets as the fund approaches its target date.&lt;/div&gt;

               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's Board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

The information shows how the fund's performance compares with the returns of an index of funds with similar investment objectives. From November 7, 2013 to November 30, 2017, the Custom Benchmark consisted of the following indices and approximate weightings: 66.50% Russell 3000 Index, 28.50% MSCI ACWI ex-USA Index, 4.00% Bloomberg Barclays U.S. Aggregate Bond Index, and 1.00% ICE Bank of America Merrill Lynch U.S. High Yield Master II Index. The weightings of the indices in the Custom Benchmark are adjusted annually to reflect changes in the fund's target asset allocation in accordance with the annual roll-down of the glide path described above.&lt;/div&gt;

Returns for Class R4 shares between those dates are those of Class 1 shares. Returns for Class R4 shares would have been substantially similar to returns of Class 1 shares because both share classes are invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.&lt;/div&gt;

Your actual after-tax returns may be different. After-tax returns are not relevant to shares held in an IRA, 401(k), or other tax-advantaged investment plan.

The example assumes a 5% average annual return and that fund expenses will not change over the periods.

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 17% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests substantially all of its assets in underlying funds using an asset allocation strategy designed for investors expected to retire around the year 2055.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The portfolio managers of the fund allocate assets among the underlying funds according to an asset allocation strategy that becomes increasingly conservative over time. John Hancock Multi-Index 2055 Lifetime Portfolio has a target asset allocation of 95% of its assets in underlying funds that invest primarily in equity securities. The fund will have a greater exposure to underlying funds that invest primarily in equity securities than will a John Hancock Multi-Index Lifetime Portfolio with a closer target date. To reduce investment risk and volatility as retirement approaches and in the postretirement years, the asset allocation strategy will change over time according to a predetermined "glide path" shown in the following chart. The fund may be a primary source of income for its shareholders after retirement.&lt;/div&gt;          
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                  GLIDE PATH CHART               
               &lt;/b&gt;&lt;/div&gt;
&lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;/div&gt;             
                &lt;img alt="glidepath chart" src="glidepath.jpg"&gt;&lt;/img&gt;        
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The allocations reflected in the glide path are referred to as target allocations because they do not reflect active decisions made by the portfolio managers to produce an overweight or an underweight position in a particular asset class. The fund has a target allocation to underlying funds that invest in the broad asset classes of equity and fixed-income securities, but may also allocate its assets to underlying funds that invest outside these asset classes to protect the fund or help it achieve its objective. For example, the fund may also allocate its assets to underlying funds that invest in alternative and specialty asset classes. The managers may change the target allocation without shareholder approval if they believe that such change would benefit the fund and its shareholders. Under normal circumstances, any deviation from the target allocation is not expected to be greater than plus or minus 10%.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Within the prescribed percentage allocation, the managers select the percentage level to be maintained in specific underlying funds. New investments made by the fund may be directed to particular underlying funds in an effort to maintain the desired target allocations. There is no guarantee that the portfolio managers will correctly predict the market or economic conditions and, as with other mutual fund investments, you could lose money even if the fund is at or close to its designated retirement year or in its postretirement stage.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is designed for investors who may remain invested in the fund through their retirement years. The fund will continue to be managed according to an allocation strategy that becomes increasingly conservative over time until approximately twenty years after retirement, at which time the fund expects to maintain a static allocation of approximately 25% of its assets in equity underlying funds.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in underlying funds that invest in a broad range of equity, fixed-income, and alternative/specialty securities and asset classes, including, but not limited to, U.S. and foreign securities, including emerging-market securities, commodities, asset-backed securities, small-cap securities, and below-investment-grade securities (i.e., junk bonds). The underlying funds may also use derivatives, such as swaps, foreign currency forwards, futures, and options, in each case for the purposes of reducing risk, obtaining efficient market exposure and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund will invest in various passively managed underlying funds that as a group hold a wide range of equity-type securities in their portfolios, including convertible securities. The fund may also invest in various actively managed funds. The fund is not designed to track an index or group of indexes. Equity-type securities include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. Certain equity underlying funds may invest in initial public offerings (IPOs). Each of the equity underlying funds has its own investment strategy that, for example, may focus on growth stocks or value stocks, or may employ a strategy combining growth and income stocks, and/or may invest in derivatives such as credit default swaps, foreign currency forwards, interest rate swaps, options on securities, and futures contracts. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from shorter to longer term. The fixed-income underlying funds collectively hold various types of debt instruments such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging market securities). Certain underlying funds may invest in illiquid securities, and certain underlying funds may be non-diversified.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest directly in exchange-traded funds (ETFs), exchange-traded notes (ETNs), the securities of other investment companies, U.S. government securities, and other types of investments such as derivatives, including credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, in each case for the purposes of reducing risk, obtaining efficient market exposure, and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;To the extent permitted by law, the Board of Trustees of the fund may, in its discretion, determine to combine the fund with another fund without shareholder approval if the target allocation of the fund matches the target allocation of the other fund, although there is no assurance that the Board of Trustees will so determine at any point. The fund bears its own expenses and, in addition, indirectly bears its proportionate share of the expenses of the underlying funds in which it invests. The fund's performance reflects both the managers' allocation decisions and the performance of the underlying funds.&lt;/div&gt;

Many factors affect performance, and fund shares will fluctuate in price, meaning you could lose money. The fund's investment strategy may not produce the intended results.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;During periods of heightened market volatility or reduced liquidity, governments, their agencies, or other regulatory bodies, both within the United States and abroad, may take steps to intervene. These actions, which could include legislative, regulatory, or economic initiatives, might have unforeseeable consequences and could adversely affect the fund's performance or otherwise constrain the fund's ability to achieve its investment objective.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in equity securities than John Hancock Multi-Index Lifetime Portfolios with closer target dates, equity security risks are more prevalent in this fund than in these other target-date funds. In addition to equity securities risk, the fund's other main risk factors are listed below in alphabetical order. &lt;i&gt;Before investing, be sure to read the additional descriptions of these risks beginning on page 68 of the prospectus.&lt;/i&gt;            
            &lt;/div&gt;

                 &lt;i&gt; Principal risks of investing in the fund of funds   &lt;/i&gt;            
               &lt;/b&gt;&lt;/div&gt;

               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk based on the nature of their support.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;

               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Investment company securities risk.&lt;/b&gt; A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;

               &lt;b&gt;Lifecycle risk.&lt;/b&gt; Managers might not correctly predict market or economic conditions, and you could lose money even close to, during, or after the fund's designated retirement year.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Target allocation risk.&lt;/b&gt; The fund's risk profile will change due to reallocation or rebalancing of portfolio assets as the fund approaches its target date.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's Board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

From March 26, 2014 to November 30, 2017, the Custom Benchmark consisted of the following indices and approximate weightings: 66.50% Russell 3000 Index, 28.50% MSCI ACWI ex-USA Index, 4.00% Bloomberg Barclays U.S. Aggregate Bond Index, and 1.00% ICE Bank of America Merrill Lynch U.S. High Yield Master II Index. The weightings of the indices in the Custom Benchmark are adjusted annually to reflect changes in the fund's target asset allocation in accordance with the annual rolldown of the glide path described above.&lt;/div&gt;

Returns for Class R4 shares between those dates are those of Class 1 shares. Returns for Class R4 shares would have been substantially similar to returns of Class 1 shares because both share classes are invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.&lt;/div&gt;

Your actual after-tax returns may be different. After-tax returns are not relevant to shares held in an IRA, 401(k), or other tax-advantaged investment plan. After-tax returns for other share classes would vary.&lt;/div&gt;

The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 24% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests substantially all of its assets in underlying funds using an asset allocation strategy designed for investors expected to retire around the year 2060.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The portfolio managers of the fund allocate assets among the underlying funds according to an asset allocation strategy that becomes increasingly conservative over time. John Hancock Multi-Index 2060 Lifetime Portfolio has a target asset allocation of 95% of its assets in underlying funds that invest primarily in equity securities. The fund will have a greater exposure to underlying funds that invest primarily in equity securities than will a John Hancock Multi-Index Lifetime Portfolio with a closer target date. To reduce investment risk and volatility as retirement approaches and in the postretirement years, the asset allocation strategy will change over time according to a predetermined "glide path" shown in the following chart. The fund may be a primary source of income for its shareholders after retirement.&lt;/div&gt;          
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                  GLIDE PATH CHART               
               &lt;/b&gt;&lt;/div&gt;      
&lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;/div&gt;       
                &lt;img alt="glidepath chart" src="glidepath.jpg"&gt;&lt;/img&gt;        
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The allocations reflected in the glide path are referred to as target allocations because they do not reflect active decisions made by the portfolio managers to produce an overweight or an underweight position in a particular asset class. The fund has a target allocation to underlying funds that invest in the broad asset classes of equity and fixed-income securities, but may also allocate its assets to underlying funds that invest outside these asset classes to protect the fund or help it achieve its objective. For example, the fund may also allocate its assets to underlying funds that invest in alternative and specialty asset classes. The managers may change the target allocation without shareholder approval if they believe that such change would benefit the fund and its shareholders. Under normal circumstances, any deviation from the target allocation is not expected to be greater than plus or minus 10%.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Within the prescribed percentage allocation, the managers select the percentage level to be maintained in specific underlying funds. New investments made by the fund may be directed to particular underlying funds in an effort to maintain the desired target allocations. There is no guarantee that the portfolio managers will correctly predict the market or economic conditions and, as with other mutual fund investments, you could lose money even if the fund is at or close to its designated retirement year or in its postretirement stage.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is designed for investors who may remain invested in the fund through their retirement years. The fund will continue to be managed according to an allocation strategy that becomes increasingly conservative over time until approximately twenty years after retirement, at which time the fund expects to maintain a static allocation of approximately 25% of its assets in equity underlying funds.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in underlying funds that invest in a broad range of equity, fixed-income, and alternative/specialty securities and asset classes, including, but not limited to, U.S. and foreign securities, including emerging-market securities, commodities, asset-backed securities, small-cap securities, and below-investment-grade securities (i.e., junk bonds). The underlying funds may also use derivatives, such as swaps, foreign currency forwards, futures, and options, in each case for the purposes of reducing risk, obtaining efficient market exposure and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund will invest in various passively managed underlying funds that as a group hold a wide range of equity-type securities in their portfolios, including convertible securities. The fund may also invest in various actively managed funds. The fund is not designed to track an index or group of indexes. Equity-type securities include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. Certain equity underlying funds may invest in initial public offerings (IPOs). Each of the equity underlying funds has its own investment strategy that, for example, may focus on growth stocks or value stocks, or may employ a strategy combining growth and income stocks, and/or may invest in derivatives such as credit default swaps, foreign currency forwards, interest rate swaps, options on securities, and futures contracts. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from shorter to longer term. The fixed-income underlying funds collectively hold various types of debt instruments such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging market securities). Certain underlying funds may invest in illiquid securities, and certain underlying funds may be non-diversified.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest directly in exchange-traded funds (ETFs), exchange-traded notes (ETNs), the securities of other investment companies, U.S. government securities, and other types of investments such as derivatives, including credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, in each case for the purposes of reducing risk, obtaining efficient market exposure, and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;To the extent permitted by law, the Board of Trustees of the fund may, in its discretion, determine to combine the fund with another fund without shareholder approval if the target allocation of the fund matches the target allocation of the other fund, although there is no assurance that the Board of Trustees will so determine at any point. The fund bears its own expenses and, in addition, indirectly bears its proportionate share of the expenses of the underlying funds in which it invests. The fund's performance reflects both the managers' allocation decisions and the performance of the underlying funds.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Many factors affect performance, and fund shares will fluctuate in price, meaning you could lose money. The fund's investment strategy may not produce the intended results.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;During periods of heightened market volatility or reduced liquidity, governments, their agencies, or other regulatory bodies, both within the United States and abroad, may take steps to intervene. These actions, which could include legislative, regulatory, or economic initiatives, might have unforeseeable consequences and could adversely affect the fund's performance or otherwise constrain the fund's ability to achieve its investment objective.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in equity securities than John Hancock Multi-Index Lifetime Portfolios with closer target dates, equity security risks are more prevalent in this fund than in these other target-date funds. In addition to equity securities risk, the fund's other main risk factors are listed below in alphabetical order. &lt;i&gt;Before investing, be sure to read the additional descriptions of these risks beginning on page 68 of the prospectus.&lt;/i&gt;            
            &lt;/div&gt;

               &lt;/b&gt;&lt;/div&gt;

               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk based on the nature of their support.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;

               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;

               &lt;b&gt;Target allocation risk.&lt;/b&gt; The fund's risk profile will change due to reallocation or rebalancing of portfolio assets as the fund approaches its target date.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;

Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;

               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;

               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;

               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;

               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;

               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;

               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;

               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;

               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's Board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;

               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The following information illustrates the variability of the fund's returns and provides some indication of the risks of investing in the fund by showing changes in the fund's performance from year to year and by showing how the fund's average annual returns compared with a broad-based market index. Past performance (before and after taxes) does not indicate future results. All figures assume dividend reinvestment. Performance information is updated daily, monthly, and quarterly and may be obtained at our website, jhinvestments.com, or by calling 888-972-8696 between 8:30 A.M. and 5:00 P.M., Eastern time, on most business days.&lt;/div&gt;

The information shows how the fund's performance compares with the returns of an index of funds with similar investment objectives. From March 30, 2016 to November 30, 2017, the Custom Benchmark consisted of the following indices and approximate weightings: 66.50% Russell 3000 Index, 28.50% MSCI ACWI ex-USA Index, 4.00% Bloomberg Barclays U.S. Aggregate Bond Index, and 1.00% ICE Bank of America Merrill Lynch U.S. High Yield Master II Index. The weightings of the indices in the Custom Benchmark are adjusted annually to reflect changes in the fund's target asset allocation in accordance with the annual rolldown of the glide path described above.&lt;/div&gt;

Returns for Class R4 shares prior to this date are those of Class 1 shares. Returns for Class R4 shares would have been substantially similar to returns of Class 1 shares because both share classes are invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.&lt;/div&gt;

Your actual after-tax returns may be different. After-tax returns are not relevant to shares held in an IRA, 401(k), or other tax-advantaged investment plan. After-tax returns for other share classes would vary.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 11% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund primarily invests its assets in underlying funds using an asset allocation strategy designed for investors expected to retire around the year 2020.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The portfolio managers of the fund allocate assets among the underlying funds according to an asset allocation strategy that becomes increasingly conservative over time. John Hancock Multi-Index 2020 Preservation Portfolio has a target asset allocation of 11.50% of its assets in underlying funds that invest primarily in equity securities. The fund will have a greater exposure to underlying funds that invest primarily in fixed-income securities than will a John Hancock Multi-Index Preservation Portfolio with a more distant target date. To attempt to reduce investment risk and volatility as retirement approaches, the asset allocation strategy will change over time according to a predetermined glide path shown in the following chart.&lt;/div&gt;         
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                  GLIDE PATH CHART               
               &lt;/b&gt;&lt;/div&gt;   
&lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;/div&gt;           
                     &lt;img alt="glidepath chart" src="glidepath1.jpg"&gt;&lt;/img&gt;   
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The allocations reflected in the glide path are referred to as neutral because they do not reflect active decisions made by the portfolio managers to produce an overweight or an underweight position in a particular asset class. The fund has a target allocation to underlying funds that invest in the broad asset classes of equity and fixed-income securities but may also allocate its assets to underlying funds that invest outside these asset classes to protect the fund or help it achieve its objective. For example, the fund may also allocate its assets to underlying funds that invest in alternative and specialty asset classes. The investment advisor may change the target allocation without shareholder approval if it believes such change would benefit the fund and its shareholders. There is no guarantee that the managers will correctly predict the market or economic conditions. There is no guarantee that the fund will preserve either income or capital and, as with other mutual fund investments, you could lose money even if the fund is at or close to its designated retirement year. Under normal circumstances, any deviation from the target allocation is not expected to be greater than plus or minus 10%.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is designed for investors who anticipate reevaluating their retirement allocation strategies at the target date. Under normal market conditions, the fund expects to allocate 8% of its assets to equity underlying funds in its designated retirement year and to maintain that static allocation thereafter. This static allocation may be appropriate for some investors, but others may wish to reallocate their investments at retirement.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in underlying funds that invest in a broad range of equity, fixed-income, and alternative/specialty securities and asset classes, including, but not limited to, U.S. and foreign securities, including emerging-market securities, commodities, asset-backed securities, small-cap securities, and below-investment-grade securities (i.e., junk bonds). The underlying funds may also use derivatives, such as swaps, foreign currency forwards, futures, and options, in each case for the purposes of reducing risk, obtaining efficient market exposure and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund will invest in various passively managed underlying funds that as a group hold a wide range of equity-type securities in their portfolios, including convertible securities. The fund may also invest in various actively managed funds. The fund is not designed to track an index or group of indexes. Equity-type securities include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. Certain equity underlying funds may invest in initial public offerings (IPOs). Each of the equity underlying funds has its own investment strategy that, for example, may focus on growth stocks or value stocks, or may employ a strategy combining growth and income stocks, and/or may invest in derivatives such as credit default swaps, foreign currency forwards, interest rate swaps, options on securities, and futures contracts. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from shorter to longer term. The fixed-income underlying funds collectively hold various types of debt instruments such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging market securities). Certain underlying funds may invest in illiquid securities, and certain underlying funds may be non-diversified.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest directly in exchange-traded funds (ETFs), exchange-traded notes (ETNs), the securities of other investment companies, U.S. government securities, and other types of investments such as derivatives, including credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, in each case for the purposes of reducing risk, obtaining efficient market exposure, and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;To the extent legally permitted, the Board of Trustees of the fund may, in its discretion, determine to combine the fund with another fund without shareholder approval if the target allocation of the fund matches the target allocation of the other fund, although there is no assurance that the Board of Trustees will so determine at any point.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund bears its own expenses and, in addition, indirectly bears its proportionate share of the expenses of the underlying funds in which it invests. The fund's performance reflects both the managers' allocation decisions and the performance of the underlying funds.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Many factors affect performance, and fund shares will fluctuate in price, meaning you could lose money. The fund's investment strategy may not produce the intended results.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;During periods of heightened market volatility or reduced liquidity, governments, their agencies, or other regulatory bodies, both within the United States and abroad, may take steps to intervene. These actions, which could include legislative, regulatory, or economic initiatives, might have unforeseeable consequences and could adversely affect the fund's performance or otherwise constrain the fund's ability to achieve its investment objective.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in fixed-income securities than John Hancock Multi-Index Preservation Portfolios with target dates that are more distant, fixed-income securities risks are more prevalent in this fund than in these other target date funds. In addition to fixed-income securities risk, the fund's other main risk factors are listed below in alphabetical order. &lt;i&gt;Before investing, be sure to read the additional descriptions of these risks beginning on page 63 of the prospectus.&lt;/i&gt;

               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk based on the nature of their support.&lt;/div&gt;

               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;

               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;

               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;

               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;

               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;

               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;

               &lt;b&gt;Target allocation risk.&lt;/b&gt; The fund's risk profile will change due to reallocation or rebalancing of portfolio assets as the fund approaches its target date.&lt;/div&gt;         
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                &lt;i&gt;  Principal risks of investing in the underlying funds    &lt;/i&gt;           
               &lt;/b&gt;&lt;/div&gt;

               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Short sales risk.&lt;/b&gt; Short sales involve costs and risk. A fund must pay the lender interest on the security it borrows, and the fund will lose money if the price of the security increases between the time of the short sale and the date when the fund replaces the borrowed security.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The following information illustrates the variability of the fund's returns and provides some indication of the risks of investing in the fund by showing changes in the fund's performance from year to year and by showing how the fund's average annual returns compared with a broad-based market index.

The information shows how the fund's performance compares with the returns of an index of funds with similar investment objectives. From December 1, 2016 to November 30, 2017, the Custom Benchmark consisted of the following indices and approximate weightings: 12.60% Russell 3000 Index, 5.40% MSCI ACWI ex-USA Index, and 82.00% Bloomberg Barclays U.S. Aggregate Bond Index. The weightings of the indices in the Custom Benchmark are adjusted annually to reflect changes in the fund's target asset allocation in accordance with the annual roll-down of the glide path described above and differed in periods prior to December 1, 2016.&lt;/div&gt;

The example assumes a 5% average annual return and that fund expenses will not change over the periods.

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 14% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund primarily invests its assets in underlying funds using an asset allocation strategy designed for investors expected to retire around the year 2025.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The portfolio managers of the fund allocate assets among the underlying funds according to an asset allocation strategy that becomes increasingly conservative over time. John Hancock Multi-Index 2025 Preservation Portfolio has a target asset allocation of 32% of its assets in underlying funds that invest primarily in equity securities. The fund will have a greater exposure to underlying funds that invest primarily in fixed-income securities than will a John Hancock Multi-Index Preservation Portfolio with a more distant target date. To attempt to reduce investment risk and volatility as retirement approaches, the asset allocation strategy will change over time according to a predetermined glide path shown in the following chart.&lt;/div&gt;         
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                  GLIDE PATH CHART               
               &lt;/b&gt;&lt;/div&gt;             
                     &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;/div&gt;  
                     &lt;img alt="glidepath chart" src="glidepath1.jpg"&gt;&lt;/img&gt; 
                    
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The allocations reflected in the glide path are referred to as neutral because they do not reflect active decisions made by the portfolio managers to produce an overweight or an underweight position in a particular asset class. The fund has a target allocation to underlying funds that invest in the broad asset classes of equity and fixed-income securities but may also allocate its assets to underlying funds that invest outside these asset classes to protect the fund or help it achieve its objective. For example, the fund may also allocate its assets to underlying funds that invest in alternative and specialty asset classes. The investment advisor may change the target allocation without shareholder approval if it believes such change would benefit the fund and its shareholders. There is no guarantee that the managers will correctly predict the market or economic conditions. There is no guarantee that the fund will preserve either income or capital and, as with other mutual fund investments, you could lose money even if the fund is at or close to its designated retirement year. Under normal circumstances, any deviation from the target allocation is not expected to be greater than plus or minus 10%.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is designed for investors who anticipate reevaluating their retirement allocation strategies at the target date. Under normal market conditions, the fund expects to allocate 8% of its assets to equity underlying funds in its designated retirement year and to maintain that static allocation thereafter. This static allocation may be appropriate for some investors, but others may wish to reallocate their investments at retirement.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in underlying funds that invest in a broad range of equity, fixed-income, and alternative/specialty securities and asset classes, including, but not limited to, U.S. and foreign securities, including emerging-market securities, commodities, asset-backed securities, small-cap securities, and below-investment-grade securities (i.e., junk bonds). The underlying funds may also use derivatives, such as swaps, foreign currency forwards, futures, and options, in each case for the purposes of reducing risk, obtaining efficient market exposure and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund will invest in various passively managed underlying funds that as a group hold a wide range of equity-type securities in their portfolios, including convertible securities. The fund may also invest in various actively managed funds. The fund is not designed to track an index or group of indexes. Equity-type securities include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. Certain equity underlying funds may invest in initial public offerings (IPOs). Each of the equity underlying funds has its own investment strategy that, for example, may focus on growth stocks or value stocks, or may employ a strategy combining growth and income stocks, and/or may invest in derivatives such as credit default swaps, foreign currency forwards, interest rate swaps, options on securities, and futures contracts. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from shorter to longer term. The fixed-income underlying funds collectively hold various types of debt instruments such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging market securities). Certain underlying funds may invest in illiquid securities, and certain underlying funds may be non-diversified.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest directly in exchange-traded funds (ETFs), exchange-traded notes (ETNs), the securities of other investment companies, U.S. government securities, and other types of investments such as derivatives, including credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, in each case for the purposes of reducing risk, obtaining efficient market exposure, and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;To the extent legally permitted, the Board of Trustees of the fund may, in its discretion, determine to combine the fund with another fund without shareholder approval if the target allocation of the fund matches the target allocation of the other fund, although there is no assurance that the Board of Trustees will so determine at any point.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund bears its own expenses and, in addition, indirectly bears its proportionate share of the expenses of the underlying funds in which it invests. The fund's performance reflects both the managers' allocation decisions and the performance of the underlying funds.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Many factors affect performance, and fund shares will fluctuate in price, meaning you could lose money. The fund's investment strategy may not produce the intended results.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;During periods of heightened market volatility or reduced liquidity, governments, their agencies, or other regulatory bodies, both within the United States and abroad, may take steps to intervene. These actions, which could include legislative, regulatory, or economic initiatives, might have unforeseeable consequences and could adversely affect the fund's performance or otherwise constrain the fund's ability to achieve its investment objective.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in fixed-income securities than John Hancock Multi-Index Preservation Portfolios with target dates that are more distant, fixed-income securities risks are more prevalent in this fund than in these other target date funds. In addition to fixed-income securities risk, the fund's other main risk factors are listed below in alphabetical order. &lt;i&gt;Before investing, be sure to read the additional descriptions of these risks beginning on page 63 of the prospectus.&lt;/i&gt;            
            &lt;/div&gt;

               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk based on the nature of their support.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;

               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;

               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;

               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;

               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;

               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality.

Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide.

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Short sales risk.&lt;/b&gt; Short sales involve costs and risk. A fund must pay the lender interest on the security it borrows, and the fund will lose money if the price of the security increases between the time of the short sale and the date when the fund replaces the borrowed security.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The following information illustrates the variability of the fund's returns and provides some indication of the risks of investing in the fund by showing changes in the fund's performance from year to year and by showing how the fund's average annual returns compared with a broad-based market index. Past performance (before and after taxes) does not indicate future results. All figures assume dividend reinvestment. Performance information is updated daily, monthly, and quarterly and may be obtained at our website, jhinvestments.com, or by calling 888-972-8696 between 8:30 A.M. and 5:00 P.M., Eastern time, on most business days.&lt;/div&gt;

The information shows how the fund's performance compares with the returns of an index of funds with similar investment objectives. From December 1, 2016 to November 30, 2017, the Custom Benchmark consisted of the following indices and approximate weightings: 28.00% Russell 3000 Index, 12.00% MSCI ACWI ex-USA Index, and 60.00% Bloomberg Barclays U.S. Aggregate Bond Index. The weightings of the indices in the Custom Benchmark are adjusted annually to reflect changes in the fund's target asset allocation in accordance with the annual roll-down of the glide path described above and differed in periods prior to December 1, 2016.&lt;/div&gt;

Class R1, Class R2, and Class R6 shares commenced operations on September 4, 2012.  Returns shown prior to a class's commencement date are those of Class 1 shares. Returns for Class R1, Class R2, Class R4, and Class R6 shares would have been substantially similar to returns of Class 1 shares because each share class is invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.&lt;/div&gt;

Your actual after-tax returns may be different. After-tax returns are not relevant to shares held in an IRA, 401(k), or other tax-advantaged investment plan.

The example assumes a 5% average annual return and that fund expenses will not change over the periods.

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 18% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund primarily invests its assets in underlying funds using an asset allocation strategy designed for investors expected to retire around the year 2030.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The portfolio managers of the fund allocate assets among the underlying funds according to an asset allocation strategy that becomes increasingly conservative over time. John Hancock Multi-Index 2030 Preservation Portfolio has a target asset allocation of 51.50% of its assets in underlying funds that invest primarily in equity securities. The fund will have a greater exposure to underlying funds that invest primarily in equity securities than will a John Hancock Multi-Index Preservation Portfolio with a closer target date. To attempt to reduce investment risk and volatility as retirement approaches, the asset allocation strategy will change over time according to a predetermined glide path shown in the following chart.&lt;/div&gt;         
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                  GLIDE PATH CHART               
               &lt;/b&gt;&lt;/div&gt;             
                &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;/div&gt;          
                     &lt;img alt="glidepath chart" src="glidepath1.jpg"&gt;&lt;/img&gt; 
                 
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The allocations reflected in the glide path are referred to as neutral because they do not reflect active decisions made by the portfolio managers to produce an overweight or an underweight position in a particular asset class. The fund has a target allocation to underlying funds that invest in the broad asset classes of equity and fixed-income securities but may also allocate its assets to underlying funds that invest outside these asset classes to protect the fund or help it achieve its objective. For example, the fund may also allocate its assets to underlying funds that invest in alternative and specialty asset classes. The investment advisor may change the target allocation without shareholder approval if it believes such change would benefit the fund and its shareholders. There is no guarantee that the managers will correctly predict the market or economic conditions. There is no guarantee that the fund will preserve either income or capital and, as with other mutual fund investments, you could lose money even if the fund is at or close to its designated retirement year. Under normal circumstances, any deviation from the target allocation is not expected to be greater than plus or minus 10%.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is designed for investors who anticipate reevaluating their retirement allocation strategies at the target date. Under normal market conditions, the fund expects to allocate 8% of its assets to equity underlying funds in its designated retirement year and to maintain that static allocation thereafter. This static allocation may be appropriate for some investors, but others may wish to reallocate their investments at retirement.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in underlying funds that invest in a broad range of equity, fixed-income, and alternative/specialty securities and asset classes, including, but not limited to, U.S. and foreign securities, including emerging-market securities, commodities, asset-backed securities, small-cap securities, and below-investment-grade securities (i.e., junk bonds). The underlying funds may also use derivatives, such as swaps, foreign currency forwards, futures, and options, in each case for the purposes of reducing risk, obtaining efficient market exposure and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund will invest in various passively managed underlying funds that as a group hold a wide range of equity-type securities in their portfolios, including convertible securities. The fund may also invest in various actively managed funds. The fund is not designed to track an index or group of indexes. Equity-type securities include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. Certain equity underlying funds may invest in initial public offerings (IPOs). Each of the equity underlying funds has its own investment strategy that, for example, may focus on growth stocks or value stocks, or may employ a strategy combining growth and income stocks, and/or may invest in derivatives such as credit default swaps, foreign currency forwards, interest rate swaps, options on securities, and futures contracts. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from shorter to longer term. The fixed-income underlying funds collectively hold various types of debt instruments such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging market securities). Certain underlying funds may invest in illiquid securities, and certain underlying funds may be non-diversified.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest directly in exchange-traded funds (ETFs), exchange-traded notes (ETNs), the securities of other investment companies, U.S. government securities, and other types of investments such as derivatives, including credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, in each case for the purposes of reducing risk, obtaining efficient market exposure, and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;To the extent legally permitted, the Board of Trustees of the fund may, in its discretion, determine to combine the fund with another fund without shareholder approval if the target allocation of the fund matches the target allocation of the other fund, although there is no assurance that the Board of Trustees will so determine at any point.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund bears its own expenses and, in addition, indirectly bears its proportionate share of the expenses of the underlying funds in which it invests. The fund's performance reflects both the managers' allocation decisions and the performance of the underlying funds.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Many factors affect performance, and fund shares will fluctuate in price, meaning you could lose money. The fund's investment strategy may not produce the intended results.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;During periods of heightened market volatility or reduced liquidity, governments, their agencies, or other regulatory bodies, both within the United States and abroad, may take steps to intervene. These actions, which could include legislative, regulatory, or economic initiatives, might have unforeseeable consequences and could adversely affect the fund's performance or otherwise constrain the fund's ability to achieve its investment objective.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in equity securities than John Hancock Multi-Index Preservation Portfolios with closer target dates, equity security risks are more prevalent in this fund than in these other target-date funds. In addition to equity securities risk, the fund's other main risk factors are listed below in alphabetical order. &lt;i&gt;Before investing, be sure to read the additional descriptions of these risks beginning on page 63 of the prospectus.&lt;/i&gt;            
            &lt;/div&gt;

               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk based on the nature of their support.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;

               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;

               &lt;b&gt;Lifecycle risk.&lt;/b&gt; Managers might not correctly predict market or economic conditions, and you could lose money even close to, during, or after the fund's designated retirement year.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Target allocation risk.&lt;/b&gt; The fund's risk profile will change due to reallocation or rebalancing of portfolio assets as the fund approaches its target date.&lt;/div&gt;

               &lt;i&gt;   Principal risks of investing in the underlying funds   &lt;/i&gt;            
               &lt;/b&gt;&lt;/div&gt;             
                     
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;

               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;

               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;

               &lt;b&gt;Short sales risk.&lt;/b&gt; Short sales involve costs and risk. A fund must pay the lender interest on the security it borrows, and the fund will lose money if the price of the security increases between the time of the short sale and the date when the fund replaces the borrowed security.&lt;/div&gt;

               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The following information illustrates the variability of the fund's returns and provides some indication of the risks of investing in the fund by showing changes in the fund's performance from year to year and by showing how the fund's average annual returns compared with a broad-based market index. Past performance (before and after taxes) does not indicate future results. All figures assume dividend reinvestment. Performance information is updated daily, monthly, and quarterly and may be obtained at our website, jhinvestments.com, or by calling 888-972-8696 between 8:30 A.M. and 5:00 P.M., Eastern time, on most business days.&lt;/div&gt;

               &lt;b&gt;Russell 3000 Index/MSCI ACWI ex-USA Index/Bloomberg Barclays U.S. Aggregate Bond Index&lt;/b&gt; This custom blended benchmark (Custom Benchmark) is based on the fund's asset allocation glide path shown above and will reflect a more conservative asset allocation over time. The information shows how the fund's performance compares with the returns of an index of funds with similar investment objectives. From December 1, 2016 to November 30, 2017, the Custom Benchmark consisted of the following indices and approximate weightings: 41.30% Russell 3000 Index, 17.70% MSCI ACWI ex-USA Index, and 41.00% Bloomberg Barclays U.S. Aggregate Bond Index. The weightings of the indices in the Custom Benchmark are adjusted annually to reflect changes in the fund's target asset allocation in accordance with the annual roll-down of the glide path described above and differed in periods prior to December 1, 2016.&lt;/div&gt;

Class R1, Class R2, and Class R6 shares commenced operations on September 4, 2012.  Returns shown prior to a class's commencement date are those of Class 1 shares. Returns for Class R1, Class R2, Class R4, and Class R6 shares would have been substantially similar to returns of Class 1 shares because each share class is invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Please note that after-tax returns (shown for Class R1 shares only) reflect the highest individual federal marginal income-tax rate in effect as of the date provided and do not reflect any state or local taxes. Your actual after-tax returns may be different. After-tax returns are not relevant to shares held in an IRA, 401(k), or other tax-advantaged investment plan. After-tax returns for other share classes would vary.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 17% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund primarily invests its assets in underlying funds using an asset allocation strategy designed for investors expected to retire around the year 2035.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The portfolio managers of the fund allocate assets among the underlying funds according to an asset allocation strategy that becomes increasingly conservative over time. John Hancock Multi-Index 2035 Preservation Portfolio has a target asset allocation of 67% of its assets in underlying funds that invest primarily in equity securities. The fund will have a greater exposure to underlying funds that invest primarily in equity securities than will a John Hancock Multi-Index Preservation Portfolio with a closer target date. To attempt to reduce investment risk and volatility as retirement approaches, the asset allocation strategy will change over time according to a predetermined glide path shown in the following chart.&lt;/div&gt;         
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                  GLIDE PATH CHART               
               &lt;/b&gt;&lt;/div&gt;             
       &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;/div&gt;                 
                     &lt;img alt="glidepath chart" src="glidepath1.jpg"&gt;&lt;/img&gt; 
                   
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The allocations reflected in the glide path are referred to as neutral because they do not reflect active decisions made by the portfolio managers to produce an overweight or an underweight position in a particular asset class. The fund has a target allocation to underlying funds that invest in the broad asset classes of equity and fixed-income securities but may also allocate its assets to underlying funds that invest outside these asset classes to protect the fund or help it achieve its objective. For example, the fund may also allocate its assets to underlying funds that invest in alternative and specialty asset classes. The investment advisor may change the target allocation without shareholder approval if it believes such change would benefit the fund and its shareholders. There is no guarantee that the managers will correctly predict the market or economic conditions. There is no guarantee that the fund will preserve either income or capital and, as with other mutual fund investments, you could lose money even if the fund is at or close to its designated retirement year. Under normal circumstances, any deviation from the target allocation is not expected to be greater than plus or minus 10%.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is designed for investors who anticipate reevaluating their retirement allocation strategies at the target date. Under normal market conditions, the fund expects to allocate 8% of its assets to equity underlying funds in its designated retirement year and to maintain that static allocation thereafter. This static allocation may be appropriate for some investors, but others may wish to reallocate their investments at retirement.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in underlying funds that invest in a broad range of equity, fixed-income, and alternative/specialty securities and asset classes, including, but not limited to, U.S. and foreign securities, including emerging-market securities, commodities, asset-backed securities, small-cap securities, and below-investment-grade securities (i.e., junk bonds). The underlying funds may also use derivatives, such as swaps, foreign currency forwards, futures, and options, in each case for the purposes of reducing risk, obtaining efficient market exposure and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund will invest in various passively managed underlying funds that as a group hold a wide range of equity-type securities in their portfolios, including convertible securities. The fund may also invest in various actively managed funds. The fund is not designed to track an index or group of indexes. Equity-type securities include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. Certain equity underlying funds may invest in initial public offerings (IPOs). Each of the equity underlying funds has its own investment strategy that, for example, may focus on growth stocks or value stocks, or may employ a strategy combining growth and income stocks, and/or may invest in derivatives such as credit default swaps, foreign currency forwards, interest rate swaps, options on securities, and futures contracts. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from shorter to longer term. The fixed-income underlying funds collectively hold various types of debt instruments such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging market securities). Certain underlying funds may invest in illiquid securities, and certain underlying funds may be non-diversified.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest directly in exchange-traded funds (ETFs), exchange-traded notes (ETNs), the securities of other investment companies, U.S. government securities, and other types of investments such as derivatives, including credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, in each case for the purposes of reducing risk, obtaining efficient market exposure, and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;To the extent legally permitted, the Board of Trustees of the fund may, in its discretion, determine to combine the fund with another fund without shareholder approval if the target allocation of the fund matches the target allocation of the other fund, although there is no assurance that the Board of Trustees will so determine at any point.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund bears its own expenses and, in addition, indirectly bears its proportionate share of the expenses of the underlying funds in which it invests. The fund's performance reflects both the managers' allocation decisions and the performance of the underlying funds.&lt;/div&gt;

Many factors affect performance, and fund shares will fluctuate in price, meaning you could lose money. The fund's investment strategy may not produce the intended results.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;During periods of heightened market volatility or reduced liquidity, governments, their agencies, or other regulatory bodies, both within the United States and abroad, may take steps to intervene. These actions, which could include legislative, regulatory, or economic initiatives, might have unforeseeable consequences and could adversely affect the fund's performance or otherwise constrain the fund's ability to achieve its investment objective.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in equity securities than John Hancock Multi-Index Preservation Portfolios with closer target dates, equity security risks are more prevalent in this fund than in these other target-date funds.

Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;

Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;

               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;

               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;

               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;

               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;

               &lt;b&gt;Lifecycle risk.&lt;/b&gt; Managers might not correctly predict market or economic conditions, and you could lose money even close to, during, or after the fund's designated retirement year.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Target allocation risk.&lt;/b&gt; The fund's risk profile will change due to reallocation or rebalancing of portfolio assets as the fund approaches its target date.&lt;/div&gt;

               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;

               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;

               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;

In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;

               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Short sales risk.&lt;/b&gt; Short sales involve costs and risk. A fund must pay the lender interest on the security it borrows, and the fund will lose money if the price of the security increases between the time of the short sale and the date when the fund replaces the borrowed security.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

The information shows how the fund's performance compares with the returns of an index of funds with similar investment objectives. From December 1, 2016 to November 30, 2017, the Custom Benchmark consisted of the following indices and approximate weightings: 49.70% Russell 3000 Index, 21.30% MSCI ACWI ex-USA Index, and 29.00% Bloomberg Barclays U.S. Aggregate Bond Index. The weightings of the indices in the Custom Benchmark are adjusted annually to reflect changes in the fund's target asset allocation in accordance with the annual roll-down of the glide path described above and differed in periods prior to December 1, 2016.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Please note that after-tax returns (shown for Class R1 shares only) reflect the highest individual federal marginal income-tax rate in effect as of the date provided and do not reflect any state or local taxes. Your actual after-tax returns may be different. After-tax returns are not relevant to shares held in an IRA, 401(k), or other tax-advantaged investment plan. After-tax returns for other share classes would vary.&lt;/div&gt;

The example assumes a 5% average annual return and that fund expenses will not change over the periods.

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 16% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund primarily invests its assets in underlying funds using an asset allocation strategy designed for investors expected to retire around the year 2040.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The portfolio managers of the fund allocate assets among the underlying funds according to an asset allocation strategy that becomes increasingly conservative over time. John Hancock Multi-Index 2040 Preservation Portfolio has a target asset allocation of 75.50% of its assets in underlying funds that invest primarily in equity securities. The fund will have a greater exposure to underlying funds that invest primarily in equity securities than will a John Hancock Multi-Index Preservation Portfolio with a closer target date. To attempt to reduce investment risk and volatility as retirement approaches, the asset allocation strategy will change over time according to a predetermined glide path shown in the following chart.&lt;/div&gt;         
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                  GLIDE PATH CHART               
               &lt;/b&gt;&lt;/div&gt;             
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;/div&gt;         
                     &lt;img alt="glidepath chart" src="glidepath1.jpg"&gt;&lt;/img&gt; 
                   
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The allocations reflected in the glide path are referred to as neutral because they do not reflect active decisions made by the portfolio managers to produce an overweight or an underweight position in a particular asset class. The fund has a target allocation to underlying funds that invest in the broad asset classes of equity and fixed-income securities but may also allocate its assets to underlying funds that invest outside these asset classes to protect the fund or help it achieve its objective. For example, the fund may also allocate its assets to underlying funds that invest in alternative and specialty asset classes. The investment advisor may change the target allocation without shareholder approval if it believes such change would benefit the fund and its shareholders. There is no guarantee that the managers will correctly predict the market or economic conditions. There is no guarantee that the fund will preserve either income or capital and, as with other mutual fund investments, you could lose money even if the fund is at or close to its designated retirement year. Under normal circumstances, any deviation from the target allocation is not expected to be greater than plus or minus 10%.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is designed for investors who anticipate reevaluating their retirement allocation strategies at the target date. Under normal market conditions, the fund expects to allocate 8% of its assets to equity underlying funds in its designated retirement year and to maintain that static allocation thereafter. This static allocation may be appropriate for some investors, but others may wish to reallocate their investments at retirement.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in underlying funds that invest in a broad range of equity, fixed-income, and alternative/specialty securities and asset classes, including, but not limited to, U.S. and foreign securities, including emerging-market securities, commodities, asset-backed securities, small-cap securities, and below-investment-grade securities (i.e., junk bonds). The underlying funds may also use derivatives, such as swaps, foreign currency forwards, futures, and options, in each case for the purposes of reducing risk, obtaining efficient market exposure and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund will invest in various passively managed underlying funds that as a group hold a wide range of equity-type securities in their portfolios, including convertible securities. The fund may also invest in various actively managed funds. The fund is not designed to track an index or group of indexes. Equity-type securities include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. Certain equity underlying funds may invest in initial public offerings (IPOs). Each of the equity underlying funds has its own investment strategy that, for example, may focus on growth stocks or value stocks, or may employ a strategy combining growth and income stocks, and/or may invest in derivatives such as credit default swaps, foreign currency forwards, interest rate swaps, options on securities, and futures contracts. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from shorter to longer term. The fixed-income underlying funds collectively hold various types of debt instruments such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging market securities). Certain underlying funds may invest in illiquid securities, and certain underlying funds may be non-diversified.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest directly in exchange-traded funds (ETFs), exchange-traded notes (ETNs), the securities of other investment companies, U.S. government securities, and other types of investments such as derivatives, including credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, in each case for the purposes of reducing risk, obtaining efficient market exposure, and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;To the extent legally permitted, the Board of Trustees of the fund may, in its discretion, determine to combine the fund with another fund without shareholder approval if the target allocation of the fund matches the target allocation of the other fund, although there is no assurance that the Board of Trustees will so determine at any point.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund bears its own expenses and, in addition, indirectly bears its proportionate share of the expenses of the underlying funds in which it invests. The fund's performance reflects both the managers' allocation decisions and the performance of the underlying funds.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Many factors affect performance, and fund shares will fluctuate in price, meaning you could lose money. The fund's investment strategy may not produce the intended results.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;During periods of heightened market volatility or reduced liquidity, governments, their agencies, or other regulatory bodies, both within the United States and abroad, may take steps to intervene. These actions, which could include legislative, regulatory, or economic initiatives, might have unforeseeable consequences and could adversely affect the fund's performance or otherwise constrain the fund's ability to achieve its investment objective.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in equity securities than John Hancock Multi-Index Preservation Portfolios with closer target dates, equity security risks are more prevalent in this fund than in these other target-date funds. In addition to equity securities risk, the fund's other main risk factors are listed below in alphabetical order. &lt;i&gt;Before investing, be sure to read the additional descriptions of these risks beginning on page 63 of the prospectus.&lt;/i&gt;

               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk based on the nature of their support.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;

               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;

               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;

               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;

               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;

               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;

               &lt;b&gt;Target allocation risk.&lt;/b&gt; The fund's risk profile will change due to reallocation or rebalancing of portfolio assets as the fund approaches its target date.&lt;/div&gt;

                 &lt;i&gt; Principal risks of investing in the underlying funds  &lt;/i&gt;             
               &lt;/b&gt;&lt;/div&gt;

               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Short sales risk.&lt;/b&gt; Short sales involve costs and risk. A fund must pay the lender interest on the security it borrows, and the fund will lose money if the price of the security increases between the time of the short sale and the date when the fund replaces the borrowed security.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The following information illustrates the variability of the fund's returns and provides some indication of the risks of investing in the fund by showing changes in the fund's performance from year to year and by showing how the fund's average annual returns compared with a broad-based market index.

The information shows how the fund's performance compares with the returns of an index of funds with similar investment objectives. From December 1, 2016 to November 30, 2017, the Custom Benchmark consisted of the following indices and approximate weightings: 54.60% Russell 3000 Index, 23.40% MSCI ACWI ex-USA Index, and 22.00% Bloomberg Barclays U.S. Aggregate Bond Index. The weightings of the indices in the Custom Benchmark are adjusted annually to reflect changes in the fund's target asset allocation in accordance with the annual roll-down of the glide path described above and differed in periods prior to December 1, 2016.&lt;/div&gt;

The example assumes a 5% average annual return and that fund expenses will not change over the periods.

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 12% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund primarily invests its assets in underlying funds using an asset allocation strategy designed for investors expected to retire around the year 2045.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The portfolio managers of the fund allocate assets among the underlying funds according to an asset allocation strategy that becomes increasingly conservative over time. John Hancock Multi-Index 2045 Preservation Portfolio has a target asset allocation of 80.50% of its assets in underlying funds that invest primarily in equity securities. The fund will have a greater exposure to underlying funds that invest primarily in equity securities than will a John Hancock Multi-Index Preservation Portfolio with a closer target date. To attempt to reduce investment risk and volatility as retirement approaches, the asset allocation strategy will change over time according to a predetermined glide path shown in the following chart.&lt;/div&gt;         
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                  GLIDE PATH CHART               
               &lt;/b&gt;&lt;/div&gt;             
         &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;/div&gt;            
                     &lt;img alt="glidepath chart" src="glidepath1.jpg"&gt;&lt;/img&gt; 
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The allocations reflected in the glide path are referred to as neutral because they do not reflect active decisions made by the portfolio managers to produce an overweight or an underweight position in a particular asset class. The fund has a target allocation to underlying funds that invest in the broad asset classes of equity and fixed-income securities but may also allocate its assets to underlying funds that invest outside these asset classes to protect the fund or help it achieve its objective. For example, the fund may also allocate its assets to underlying funds that invest in alternative and specialty asset classes. The investment advisor may change the target allocation without shareholder approval if it believes such change would benefit the fund and its shareholders. There is no guarantee that the managers will correctly predict the market or economic conditions. There is no guarantee that the fund will preserve either income or capital and, as with other mutual fund investments, you could lose money even if the fund is at or close to its designated retirement year. Under normal circumstances, any deviation from the target allocation is not expected to be greater than plus or minus 10%.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is designed for investors who anticipate reevaluating their retirement allocation strategies at the target date. Under normal market conditions, the fund expects to allocate 8% of its assets to equity underlying funds in its designated retirement year and to maintain that static allocation thereafter. This static allocation may be appropriate for some investors, but others may wish to reallocate their investments at retirement.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in underlying funds that invest in a broad range of equity, fixed-income, and alternative/specialty securities and asset classes, including, but not limited to, U.S. and foreign securities, including emerging-market securities, commodities, asset-backed securities, small-cap securities, and below-investment-grade securities (i.e., junk bonds). The underlying funds may also use derivatives, such as swaps, foreign currency forwards, futures, and options, in each case for the purposes of reducing risk, obtaining efficient market exposure and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund will invest in various passively managed underlying funds that as a group hold a wide range of equity-type securities in their portfolios, including convertible securities. The fund may also invest in various actively managed funds. The fund is not designed to track an index or group of indexes. Equity-type securities include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. Certain equity underlying funds may invest in initial public offerings (IPOs). Each of the equity underlying funds has its own investment strategy that, for example, may focus on growth stocks or value stocks, or may employ a strategy combining growth and income stocks, and/or may invest in derivatives such as credit default swaps, foreign currency forwards, interest rate swaps, options on securities, and futures contracts. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from shorter to longer term. The fixed-income underlying funds collectively hold various types of debt instruments such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging market securities). Certain underlying funds may invest in illiquid securities, and certain underlying funds may be non-diversified.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest directly in exchange-traded funds (ETFs), exchange-traded notes (ETNs), the securities of other investment companies, U.S. government securities, and other types of investments such as derivatives, including credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, in each case for the purposes of reducing risk, obtaining efficient market exposure, and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;To the extent legally permitted, the Board of Trustees of the fund may, in its discretion, determine to combine the fund with another fund without shareholder approval if the target allocation of the fund matches the target allocation of the other fund, although there is no assurance that the Board of Trustees will so determine at any point.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund bears its own expenses and, in addition, indirectly bears its proportionate share of the expenses of the underlying funds in which it invests. The fund's performance reflects both the managers' allocation decisions and the performance of the underlying funds.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Many factors affect performance, and fund shares will fluctuate in price, meaning you could lose money. The fund's investment strategy may not produce the intended results.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;During periods of heightened market volatility or reduced liquidity, governments, their agencies, or other regulatory bodies, both within the United States and abroad, may take steps to intervene. These actions, which could include legislative, regulatory, or economic initiatives, might have unforeseeable consequences and could adversely affect the fund's performance or otherwise constrain the fund's ability to achieve its investment objective.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in equity securities than John Hancock Multi-Index Preservation Portfolios with closer target dates, equity security risks are more prevalent in this fund than in these other target-date funds. In addition to equity securities risk, the fund's other main risk factors are listed below in alphabetical order. &lt;i&gt;Before investing, be sure to read the additional descriptions of these risks beginning on page 63 of the prospectus.&lt;/i&gt;            
            &lt;/div&gt;

               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk based on the nature of their support.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;

               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;

               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;

               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;

               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;

               &lt;b&gt;Target allocation risk.&lt;/b&gt; The fund's risk profile will change due to reallocation or rebalancing of portfolio assets as the fund approaches its target date.&lt;/div&gt;

               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;

               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality.

Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Short sales risk.&lt;/b&gt; Short sales involve costs and risk. A fund must pay the lender interest on the security it borrows, and the fund will lose money if the price of the security increases between the time of the short sale and the date when the fund replaces the borrowed security.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The following information illustrates the variability of the fund's returns and provides some indication of the risks of investing in the fund by showing changes in the fund's performance from year to year and by showing how the fund's average annual returns compared with a broad-based market index. Past performance (before and after taxes) does not indicate future results. All figures assume dividend reinvestment. Performance information is updated daily, monthly, and quarterly and may be obtained at our website, jhinvestments.com, or by calling 888-972-8696 between 8:30 A.M. and 5:00 P.M., Eastern time, on most business days.&lt;/div&gt;

The information shows how the fund's performance compares with the returns of an index of funds with similar investment objectives. From December 1, 2016 to November 30, 2017, the Custom Benchmark consisted of the following indices and approximate weightings: 57.05% Russell 3000 Index, 24.45% MSCI ACWI ex-USA Index, and 18.50% Bloomberg Barclays U.S. Aggregate Bond Index. The weightings of the indices in the Custom Benchmark are adjusted annually to reflect changes in the fund's target asset allocation in accordance with the annual roll-down of the glide path described above.&lt;/div&gt;

Class R1, Class R2, and Class R6 shares commenced operations on September 4, 2012.  Returns shown prior to a class's commencement date are those of Class 1 shares. Returns for Class R1, Class R2, Class R4, and Class R6 shares would have been substantially similar to returns of Class 1 shares because each share class is invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.&lt;/div&gt;

Your actual after-tax returns may be different. After-tax returns are not relevant to shares held in an IRA, 401(k), or other tax-advantaged investment plan.

The example assumes a 5% average annual return and that fund expenses will not change over the periods.

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 13% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund primarily invests its assets in underlying funds using an asset allocation strategy designed for investors expected to retire around the year 2050.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The portfolio managers of the fund allocate assets among the underlying funds according to an asset allocation strategy that becomes increasingly conservative over time. John Hancock Multi-Index 2050 Preservation Portfolio has a target asset allocation of 82% of its assets in underlying funds that invest primarily in equity securities. The fund will have a greater exposure to underlying funds that invest primarily in equity securities than will a John Hancock Multi-Index Preservation Portfolio with a closer target date. To attempt to reduce investment risk and volatility as retirement approaches, the asset allocation strategy will change over time according to a predetermined glide path shown in the following chart.&lt;/div&gt;          
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                  GLIDE PATH CHART               
               &lt;/b&gt;&lt;/div&gt;
&lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;/div&gt;             
                        &lt;img alt="glidepath chart" src="glidepath1.jpg"&gt;&lt;/img&gt; 
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The allocations reflected in the glide path are referred to as neutral because they do not reflect active decisions made by the portfolio managers to produce an overweight or an underweight position in a particular asset class. The fund has a target allocation to underlying funds that invest in the broad asset classes of equity and fixed-income securities but may also allocate its assets to underlying funds that invest outside these asset classes to protect the fund or help it achieve its objective. For example, the fund may also allocate its assets to underlying funds that invest in alternative and specialty asset classes. The investment advisor may change the target allocation without shareholder approval if it believes such change would benefit the fund and its shareholders. There is no guarantee that the managers will correctly predict the market or economic conditions. There is no guarantee that the fund will preserve either income or capital and, as with other mutual fund investments, you could lose money even if the fund is at or close to its designated retirement year. Under normal circumstances, any deviation from the target allocation is not expected to be greater than plus or minus 10%.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is designed for investors who anticipate reevaluating their retirement allocation strategies at the target date. Under normal market conditions, the fund expects to allocate 8% of its assets to equity underlying funds in its designated retirement year and to maintain that static allocation thereafter. This static allocation may be appropriate for some investors, but others may wish to reallocate their investments at retirement.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in underlying funds that invest in a broad range of equity, fixed-income, and alternative/specialty securities and asset classes, including, but not limited to, U.S. and foreign securities, including emerging-market securities, commodities, asset-backed securities, small-cap securities, and below-investment-grade securities (i.e., junk bonds). The underlying funds may also use derivatives, such as swaps, foreign currency forwards, futures, and options, in each case for the purposes of reducing risk, obtaining efficient market exposure and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund will invest in various passively managed underlying funds that as a group hold a wide range of equity-type securities in their portfolios, including convertible securities. The fund may also invest in various actively managed funds. The fund is not designed to track an index or group of indexes. Equity-type securities include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. Certain equity underlying funds may invest in initial public offerings (IPOs). Each of the equity underlying funds has its own investment strategy that, for example, may focus on growth stocks or value stocks, or may employ a strategy combining growth and income stocks, and/or may invest in derivatives such as credit default swaps, foreign currency forwards, interest rate swaps, options on securities, and futures contracts. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from shorter to longer term. The fixed-income underlying funds collectively hold various types of debt instruments such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging market securities). Certain underlying funds may invest in illiquid securities, and certain underlying funds may be non-diversified.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest directly in exchange-traded funds (ETFs), exchange-traded notes (ETNs), the securities of other investment companies, U.S. government securities, and other types of investments such as derivatives, including credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, in each case for the purposes of reducing risk, obtaining efficient market exposure, and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;To the extent legally permitted, the Board of Trustees of the fund may, in its discretion, determine to combine the fund with another fund without shareholder approval if the target allocation of the fund matches the target allocation of the other fund, although there is no assurance that the Board of Trustees will so determine at any point.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund bears its own expenses and, in addition, indirectly bears its proportionate share of the expenses of the underlying funds in which it invests. The fund's performance reflects both the managers' allocation decisions and the performance of the underlying funds.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Many factors affect performance, and fund shares will fluctuate in price, meaning you could lose money. The fund's investment strategy may not produce the intended results.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;During periods of heightened market volatility or reduced liquidity, governments, their agencies, or other regulatory bodies, both within the United States and abroad, may take steps to intervene. These actions, which could include legislative, regulatory, or economic initiatives, might have unforeseeable consequences and could adversely affect the fund's performance or otherwise constrain the fund's ability to achieve its investment objective.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in equity securities than John Hancock Multi-Index Preservation Portfolios with closer target dates, equity security risks are more prevalent in this fund than in these other target-date funds. In addition to equity securities risk, the fund's other main risk factors are listed below in alphabetical order. &lt;i&gt;Before investing, be sure to read the additional descriptions of these risks beginning on page 63 of the prospectus.&lt;/i&gt;            
            &lt;/div&gt;

               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk based on the nature of their support.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;

               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;

               &lt;b&gt;Lifecycle risk.&lt;/b&gt; Managers might not correctly predict market or economic conditions, and you could lose money even close to, during, or after the fund's designated retirement year.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Target allocation risk.&lt;/b&gt; The fund's risk profile will change due to reallocation or rebalancing of portfolio assets as the fund approaches its target date.&lt;/div&gt;

               &lt;i&gt;   Principal risks of investing in the underlying funds   &lt;/i&gt;            
               &lt;/b&gt;&lt;/div&gt;             
                     
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;

               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;

               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;

               &lt;b&gt;Short sales risk.&lt;/b&gt; Short sales involve costs and risk. A fund must pay the lender interest on the security it borrows, and the fund will lose money if the price of the security increases between the time of the short sale and the date when the fund replaces the borrowed security.&lt;/div&gt;

               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The following information illustrates the variability of the fund's returns and provides some indication of the risks of investing in the fund by showing changes in the fund's performance from year to year and by showing how the fund's average annual returns compared with a broad-based market index. Past performance (before and after taxes) does not indicate future results. All figures assume dividend reinvestment. Performance information is updated daily, monthly, and quarterly and may be obtained at our website, jhinvestments.com, or by calling 888-972-8696 between 8:30 A.M. and 5:00 P.M., Eastern time, on most business days.&lt;/div&gt;

               &lt;b&gt;Russell 3000 Index/MSCI ACWI ex-USA Index/Bloomberg Barclays U.S. Aggregate Bond Index&lt;/b&gt; This custom blended benchmark (Custom Benchmark) is based on the fund's asset allocation glide path shown above and will reflect a more conservative asset allocation over time. The information shows how the fund's performance compares with the returns of an index of funds with similar investment objectives. From April 29, 2011 to November 30, 2017, the Custom Benchmark consisted of the following indices and approximate weightings: 57.40% Russell 3000 Index, 24.60% MSCI ACWI ex-USA Index, and 18.00% Bloomberg Barclays U.S. Aggregate Bond Index. The weightings of the indices in the Custom Benchmark are adjusted annually to reflect changes in the fund's target asset allocation in accordance with the annual roll-down of the glide path described above.&lt;/div&gt;

Class R1, Class R2, and Class R6 shares commenced operations on September 4, 2012.  Returns shown prior to a class's commencement date are those of Class 1 shares. Returns for Class R1, Class R2, Class R4, and Class R6 shares would have been substantially similar to returns of Class 1 shares because each share class is invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Please note that after-tax returns (shown for Class R1 shares only) reflect the highest individual federal marginal income-tax rate in effect as of the date provided and do not reflect any state or local taxes. Your actual after-tax returns may be different. After-tax returns are not relevant to shares held in an IRA, 401(k), or other tax-advantaged investment plan. After-tax returns for other share classes would vary.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 10% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund primarily invests its assets in underlying funds using an asset allocation strategy designed for investors expected to retire around the year 2055.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The portfolio managers of the fund allocate assets among the underlying funds according to an asset allocation strategy that becomes increasingly conservative over time. John Hancock Multi-Index 2055 Preservation Portfolio has a target asset allocation of 82% of its assets in underlying funds that invest primarily in equity securities. The fund will have a greater exposure to underlying funds that invest primarily in equity securities than will a John Hancock Multi-Index Preservation Portfolio with a closer target date. To attempt to reduce investment risk and volatility as retirement approaches, the asset allocation strategy will change over time according to a predetermined glide path shown in the following chart.&lt;/div&gt;          
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                  GLIDE PATH CHART               
               &lt;/b&gt;&lt;/div&gt;             
 &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;/div&gt;  
                       &lt;img alt="glidepath chart" src="glidepath1.jpg"&gt;&lt;/img&gt;  
                  
                   
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The allocations reflected in the glide path are referred to as neutral because they do not reflect active decisions made by the portfolio managers to produce an overweight or an underweight position in a particular asset class. The fund has a target allocation to underlying funds that invest in the broad asset classes of equity and fixed-income securities but may also allocate its assets to underlying funds that invest outside these asset classes to protect the fund or help it achieve its objective. For example, the fund may also allocate its assets to underlying funds that invest in alternative and specialty asset classes. The investment advisor may change the target allocation without shareholder approval if it believes such change would benefit the fund and its shareholders. There is no guarantee that the managers will correctly predict the market or economic conditions. There is no guarantee that the fund will preserve either income or capital and, as with other mutual fund investments, you could lose money even if the fund is at or close to its designated retirement year. Under normal circumstances, any deviation from the target allocation is not expected to be greater than plus or minus 10%.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is designed for investors who anticipate reevaluating their retirement allocation strategies at the target date. Under normal market conditions, the fund expects to allocate 8% of its assets to equity underlying funds in its designated retirement year and to maintain that static allocation thereafter. This static allocation may be appropriate for some investors, but others may wish to reallocate their investments at retirement.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in underlying funds that invest in a broad range of equity, fixed-income, and alternative/specialty securities and asset classes, including, but not limited to, U.S. and foreign securities, including emerging-market securities, commodities, asset-backed securities, small-cap securities, and below-investment-grade securities (i.e., junk bonds). The underlying funds may also use derivatives, such as swaps, foreign currency forwards, futures, and options, in each case for the purposes of reducing risk, obtaining efficient market exposure and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund will invest in various passively managed underlying funds that as a group hold a wide range of equity-type securities in their portfolios, including convertible securities. The fund may also invest in various actively managed funds. The fund is not designed to track an index or group of indexes. Equity-type securities include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. Certain equity underlying funds may invest in initial public offerings (IPOs). Each of the equity underlying funds has its own investment strategy that, for example, may focus on growth stocks or value stocks, or may employ a strategy combining growth and income stocks, and/or may invest in derivatives such as credit default swaps, foreign currency forwards, interest rate swaps, options on securities, and futures contracts. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from shorter to longer term. The fixed-income underlying funds collectively hold various types of debt instruments such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging market securities). Certain underlying funds may invest in illiquid securities, and certain underlying funds may be non-diversified.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest directly in exchange-traded funds (ETFs), exchange-traded notes (ETNs), the securities of other investment companies, U.S. government securities, and other types of investments such as derivatives, including credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, in each case for the purposes of reducing risk, obtaining efficient market exposure, and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;To the extent legally permitted, the Board of Trustees of the fund may, in its discretion, determine to combine the fund with another fund without shareholder approval if the target allocation of the fund matches the target allocation of the other fund, although there is no assurance that the Board of Trustees will so determine at any point.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund bears its own expenses and, in addition, indirectly bears its proportionate share of the expenses of the underlying funds in which it invests. The fund's performance reflects both the managers' allocation decisions and the performance of the underlying funds.&lt;/div&gt;

Many factors affect performance, and fund shares will fluctuate in price, meaning you could lose money. The fund's investment strategy may not produce the intended results.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;During periods of heightened market volatility or reduced liquidity, governments, their agencies, or other regulatory bodies, both within the United States and abroad, may take steps to intervene. These actions, which could include legislative, regulatory, or economic initiatives, might have unforeseeable consequences and could adversely affect the fund's performance or otherwise constrain the fund's ability to achieve its investment objective.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in equity securities than John Hancock Multi-Index Preservation Portfolios with closer target dates, equity security risks are more prevalent in this fund than in these other target-date funds. In addition to equity securities risk, the fund's other main risk factors are listed below in alphabetical order. &lt;i&gt;Before investing, be sure to read the additional descriptions of these risks beginning on page 63 of the prospectus.&lt;/i&gt;

               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;

Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;

               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;

               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;

               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;

               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Investment company securities risk.&lt;/b&gt; A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lifecycle risk.&lt;/b&gt; Managers might not correctly predict market or economic conditions, and you could lose money even close to, during, or after the fund's designated retirement year.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Target allocation risk.&lt;/b&gt; The fund's risk profile will change due to reallocation or rebalancing of portfolio assets as the fund approaches its target date.&lt;/div&gt;

               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;

               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;

Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;

               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;

               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Short sales risk.&lt;/b&gt; Short sales involve costs and risk. A fund must pay the lender interest on the security it borrows, and the fund will lose money if the price of the security increases between the time of the short sale and the date when the fund replaces the borrowed security.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

The information shows how the fund's performance compares with the returns of an index of funds with similar investment objectives. From March 26, 2014 to November 30, 2017, the Custom Benchmark consisted of the following indices and approximate weightings: 57.40% Russell 3000 Index, 24.60% MSCI ACWI ex-USA Index, and 18.00% Bloomberg Barclays U.S. Aggregate Bond Index. The weightings of the indices in the Custom Benchmark are adjusted annually to reflect changes in the fund's target asset allocation in accordance with the annual roll-down of the glide path described above.&lt;/div&gt;

Please see below a hypothetical example showing the expenses of a $10,000 investment for the time periods indicated and then assuming you sell all of your shares at the end of those periods. The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 10% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund primarily invests its assets in underlying funds using an asset allocation strategy designed for investors expected to retire around the year 2060.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The portfolio managers of the fund allocate assets among the underlying funds according to an asset allocation strategy that becomes increasingly conservative over time. John Hancock Multi-Index 2060 Preservation Portfolio has a target asset allocation of 82% of its assets in underlying funds that invest primarily in equity securities. The fund will have a greater exposure to underlying funds that invest primarily in equity securities than will a John Hancock Multi-Index Preservation Portfolio with a closer target date. To attempt to reduce investment risk and volatility as retirement approaches, the asset allocation strategy will change over time according to a predetermined glide path shown in the following chart.&lt;/div&gt;          
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                  GLIDE PATH CHART               
               &lt;/b&gt;&lt;/div&gt;             
 &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;/div&gt;
                       &lt;img alt="glidepath chart" src="glidepath1.jpg"&gt;&lt;/img&gt;  
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The allocations reflected in the glide path are referred to as neutral because they do not reflect active decisions made by the portfolio managers to produce an overweight or an underweight position in a particular asset class. The fund has a target allocation to underlying funds that invest in the broad asset classes of equity and fixed-income securities but may also allocate its assets to underlying funds that invest outside these asset classes to protect the fund or help it achieve its objective. For example, the fund may also allocate its assets to underlying funds that invest in alternative and specialty asset classes. The investment advisor may change the target allocation without shareholder approval if it believes such change would benefit the fund and its shareholders. There is no guarantee that the managers will correctly predict the market or economic conditions. There is no guarantee that the fund will preserve either income or capital and, as with other mutual fund investments, you could lose money even if the fund is at or close to its designated retirement year. Under normal circumstances, any deviation from the target allocation is not expected to be greater than plus or minus 10%.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is designed for investors who anticipate reevaluating their retirement allocation strategies at the target date. Under normal market conditions, the fund expects to allocate 8% of its assets to equity underlying funds in its designated retirement year and to maintain that static allocation thereafter. This static allocation may be appropriate for some investors, but others may wish to reallocate their investments at retirement.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in underlying funds that invest in a broad range of equity, fixed-income, and alternative/specialty securities and asset classes, including, but not limited to, U.S. and foreign securities, including emerging-market securities, commodities, asset-backed securities, small-cap securities, and below-investment-grade securities (i.e., junk bonds). The underlying funds may also use derivatives, such as swaps, foreign currency forwards, futures, and options, in each case for the purposes of reducing risk, obtaining efficient market exposure and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund will invest in various passively managed underlying funds that as a group hold a wide range of equity-type securities in their portfolios, including convertible securities. The fund may also invest in various actively managed funds. The fund is not designed to track an index or group of indexes. Equity-type securities include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. Certain equity underlying funds may invest in initial public offerings (IPOs). Each of the equity underlying funds has its own investment strategy that, for example, may focus on growth stocks or value stocks, or may employ a strategy combining growth and income stocks, and/or may invest in derivatives such as credit default swaps, foreign currency forwards, interest rate swaps, options on securities, and futures contracts. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from shorter to longer term. The fixed-income underlying funds collectively hold various types of debt instruments such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging market securities). Certain underlying funds may invest in illiquid securities, and certain underlying funds may be non-diversified.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest directly in exchange-traded funds (ETFs), exchange-traded notes (ETNs), the securities of other investment companies, U.S. government securities, and other types of investments such as derivatives, including credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, in each case for the purposes of reducing risk, obtaining efficient market exposure, and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;To the extent legally permitted, the Board of Trustees of the fund may, in its discretion, determine to combine the fund with another fund without shareholder approval if the target allocation of the fund matches the target allocation of the other fund, although there is no assurance that the Board of Trustees will so determine at any point.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund bears its own expenses and, in addition, indirectly bears its proportionate share of the expenses of the underlying funds in which it invests. The fund's performance reflects both the managers' allocation decisions and the performance of the underlying funds.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Many factors affect performance, and fund shares will fluctuate in price, meaning you could lose money. The fund's investment strategy may not produce the intended results.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;During periods of heightened market volatility or reduced liquidity, governments, their agencies, or other regulatory bodies, both within the United States and abroad, may take steps to intervene. These actions, which could include legislative, regulatory, or economic initiatives, might have unforeseeable consequences and could adversely affect the fund's performance or otherwise constrain the fund's ability to achieve its investment objective.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in equity securities than John Hancock Multi-Index Preservation Portfolios with closer target dates, equity security risks are more prevalent in this fund than in these other target-date funds. In addition to equity securities risk, the fund's other main risk factors are listed below in alphabetical order. &lt;i&gt;Before investing, be sure to read the additional descriptions of these risks beginning on page 63 of the prospectus.&lt;/i&gt;            
            &lt;/div&gt;

               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk based on the nature of their support.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;

               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;

               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;

               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;

               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;

               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;

               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;

               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;

Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Short sales risk.&lt;/b&gt; Short sales involve costs and risk. A fund must pay the lender interest on the security it borrows, and the fund will lose money if the price of the security increases between the time of the short sale and the date when the fund replaces the borrowed security.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

The information shows how the fund's performance compares with the returns of an index of funds with similar investment objectives. From March 30, 2016 to November 30, 2017, the Custom Benchmark consisted of the following indices and approximate weightings: 57.40% Russell 3000 Index, 24.60% MSCI ACWI ex-USA Index, and 18.00% Bloomberg Barclays U.S. Aggregate Bond Index. The weightings of the indices in the Custom Benchmark are adjusted annually to reflect changes in the fund's target asset allocation in accordance with the annual roll-down of the glide path described above.&lt;/div&gt;

Please see below a hypothetical example showing the expenses of a $10,000 investment for the time periods indicated and then assuming you sell all of your shares at the end of those periods. The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 7% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund primarily invests its assets in underlying funds using an asset allocation strategy designed for investors in or near retirement. Under normal market conditions, the fund is expected to maintain an allocation of about 8% of its assets in underlying funds that invest primarily in equity securities.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund typically will have greater exposure to underlying funds that invest primarily in fixed-income securities than will other John Hancock Multi-Index Preservation Portfolios, which are designed for investors who plan to retire around a specific target date.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund's allocations to equity and fixed-income are referred to as neutral because they do not reflect active decisions made by the portfolio managers to produce an overweight or an underweight position in a particular asset class. The fund has a target allocation to underlying funds that invest in the broad asset classes of equity and fixed-income securities but may also allocate its assets to underlying funds that invest outside these asset classes to protect the fund or help it achieve its objective. For example, the fund may also allocate its assets to underlying funds that invest in alternative and specialty asset classes. The investment advisor may change the target allocation without shareholder approval if it believes such change would benefit the fund and its shareholders. There is no guarantee that the managers will correctly predict the market or economic conditions. There is no guarantee that the fund will preserve either income or capital and, as with other mutual fund investments, you could lose money. Unlike other John Hancock Multi-Index Preservation Portfolios, the fund is not designed to decrease its equity holdings over time. The fund is designed for an investor in or near retirement, and it is anticipated that investors will make gradual withdrawals from the fund.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in underlying funds that invest in a broad range of equity, fixed-income, and alternative/specialty securities and asset classes, including, but not limited to, U.S. and foreign securities, including emerging-market securities, commodities, asset-backed securities, small-cap securities, and below-investment-grade securities (i.e., junk bonds). The underlying funds may also use derivatives, such as swaps, foreign currency forwards, futures, and options, in each case for the purposes of reducing risk, obtaining efficient market exposure and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund will invest in various passively managed underlying funds that as a group hold a wide range of equity-type securities in their portfolios, including convertible securities. The fund may also invest in various actively managed funds. The fund is not designed to track an index or group of indexes. Equity-type securities include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. Certain equity underlying funds may invest in initial public offerings (IPOs). Each of the equity underlying funds has its own investment strategy that, for example, may focus on growth stocks or value stocks, or may employ a strategy combining growth and income stocks, and/or may invest in derivatives such as credit default swaps, foreign currency forwards, interest rate swaps, options on securities, and futures contracts. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from shorter to longer term. The fixed-income underlying funds collectively hold various types of debt instruments such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging market securities). Certain underlying funds may invest in illiquid securities, and certain underlying funds may be non-diversified.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest directly in exchange-traded funds (ETFs), exchange-traded notes (ETNs), the securities of other investment companies, U.S. government securities, and other types of investments such as derivatives, including credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, in each case for the purposes of reducing risk, obtaining efficient market exposure, and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;To the extent legally permitted, the Board of Trustees of the fund may, in its discretion, determine to combine the fund with another fund without shareholder approval if the target allocation of the fund matches the target allocation of the other fund, although there is no assurance that the Board of Trustees will so determine at any point.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund bears its own expenses and, in addition, indirectly bears its proportionate share of the expenses of the underlying funds in which it invests. The fund's performance reflects both the managers' allocation decisions and the performance of the underlying funds.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;During periods of heightened market volatility or reduced liquidity, governments, their agencies, or other regulatory bodies, both within the United States and abroad, may take steps to intervene. These actions, which could include legislative, regulatory, or economic initiatives, might have unforeseeable consequences and could adversely affect the fund's performance or otherwise constrain the fund's ability to achieve its investment objective.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in fixed-income securities than John Hancock Multi-Index Preservation Portfolios with target dates that are more distant, fixed-income securities risks are more prevalent in this fund than in these other target date funds. In addition to fixed-income securities risk, the fund's other main risk factors are listed below in alphabetical order. &lt;i&gt;Before investing, be sure to read the additional descriptions of these risks beginning on page 63 of the prospectus.&lt;/i&gt;            
            &lt;/div&gt;

                &lt;i&gt;  Principal risks of investing in the fund of funds  &lt;/i&gt;             
               &lt;/b&gt;&lt;/div&gt;             
                     
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk based on the nature of their support.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Investment company securities risk.&lt;/b&gt; A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lifecycle risk.&lt;/b&gt; Managers might not correctly predict market or economic conditions, and you could lose money even though the fund's designated retirement year has already passed.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Target allocation risk.&lt;/b&gt; The fund's risk profile will change due to reallocation or rebalancing of portfolio assets as the fund approaches its target date.&lt;/div&gt;         
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
              &lt;i&gt;    Principal risks of investing in the underlying funds  &lt;/i&gt;             
               &lt;/b&gt;&lt;/div&gt;             
                     
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Short sales risk.&lt;/b&gt; Short sales involve costs and risk. A fund must pay the lender interest on the security it borrows, and the fund will lose money if the price of the security increases between the time of the short sale and the date when the fund replaces the borrowed security.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

               &lt;b&gt;Russell 3000 Index/MSCI ACWI ex-USA Index/Bloomberg Barclays U.S. Aggregate Bond Index&lt;/b&gt; This custom blended benchmark (Custom Benchmark) is designed to reflect the fund's asset allocation under normal market conditions. The information shows how the fund's performance compares with the returns of an index of funds with similar investment objectives. From December 1, 2014, the Custom Benchmark has consisted of the following indices and approximate weightings: 5.60% Russell 3000 Index, 2.40% MSCI ACWI ex-USA Index, and 92.00% Bloomberg Barclays U.S. Aggregate Bond Index. Prior to reaching its current allocation, the weightings of the indices in the Custom Benchmark were adjusted annually to reflect changes in the fund's target asset allocation.&lt;/div&gt;

Class R1, Class R2, and Class R6 shares commenced operations on September 4, 2012.  Returns shown prior to a class's commencement date are those of Class 1 shares. Returns for Class R1, Class R2, Class R4, and Class R6 shares would have been substantially similar to returns of Class 1 shares because each share class is invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Please note that after-tax returns (shown for Class R1 shares only) reflect the highest individual federal marginal income-tax rate in effect as of the date provided and do not reflect any state or local taxes. Your actual after-tax returns may be different. After-tax returns are not relevant to shares held in an IRA, 401(k), or other tax-advantaged investment plan. After-tax returns for other share classes would vary.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 11% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund primarily invests its assets in underlying funds using an asset allocation strategy designed for investors expected to retire around the year 2020.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The portfolio managers of the fund allocate assets among the underlying funds according to an asset allocation strategy that becomes increasingly conservative over time. John Hancock Multi-Index 2020 Preservation Portfolio has a target asset allocation of 11.50% of its assets in underlying funds that invest primarily in equity securities. The fund will have a greater exposure to underlying funds that invest primarily in fixed-income securities than will a John Hancock Multi-Index Preservation Portfolio with a more distant target date. To attempt to reduce investment risk and volatility as retirement approaches, the asset allocation strategy will change over time according to a predetermined glide path shown in the following chart.&lt;/div&gt;         
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                  GLIDE PATH CHART               
               &lt;/b&gt;&lt;/div&gt;             
                     &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;/div&gt; 
                     &lt;img alt="glidepath chart" src="glidepath1.jpg"&gt;&lt;/img&gt; 
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The allocations reflected in the glide path are referred to as neutral because they do not reflect active decisions made by the portfolio managers to produce an overweight or an underweight position in a particular asset class. The fund has a target allocation to underlying funds that invest in the broad asset classes of equity and fixed-income securities but may also allocate its assets to underlying funds that invest outside these asset classes to protect the fund or help it achieve its objective. For example, the fund may also allocate its assets to underlying funds that invest in alternative and specialty asset classes. The investment advisor may change the target allocation without shareholder approval if it believes such change would benefit the fund and its shareholders. There is no guarantee that the managers will correctly predict the market or economic conditions. There is no guarantee that the fund will preserve either income or capital and, as with other mutual fund investments, you could lose money even if the fund is at or close to its designated retirement year. Under normal circumstances, any deviation from the target allocation is not expected to be greater than plus or minus 10%.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is designed for investors who anticipate reevaluating their retirement allocation strategies at the target date. Under normal market conditions, the fund expects to allocate 8% of its assets to equity underlying funds in its designated retirement year and to maintain that static allocation thereafter. This static allocation may be appropriate for some investors, but others may wish to reallocate their investments at retirement.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in underlying funds that invest in a broad range of equity, fixed-income, and alternative/specialty securities and asset classes, including, but not limited to, U.S. and foreign securities, including emerging-market securities, commodities, asset-backed securities, small-cap securities, and below-investment-grade securities (i.e., junk bonds). The underlying funds may also use derivatives, such as swaps, foreign currency forwards, futures, and options, in each case for the purposes of reducing risk, obtaining efficient market exposure and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund will invest in various passively managed underlying funds that as a group hold a wide range of equity-type securities in their portfolios, including convertible securities. The fund may also invest in various actively managed funds. The fund is not designed to track an index or group of indexes. Equity-type securities include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. Certain equity underlying funds may invest in initial public offerings (IPOs). Each of the equity underlying funds has its own investment strategy that, for example, may focus on growth stocks or value stocks, or may employ a strategy combining growth and income stocks, and/or may invest in derivatives such as credit default swaps, foreign currency forwards, interest rate swaps, options on securities, and futures contracts. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from shorter to longer term. The fixed-income underlying funds collectively hold various types of debt instruments such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging market securities). Certain underlying funds may invest in illiquid securities, and certain underlying funds may be non-diversified.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest directly in exchange-traded funds (ETFs), exchange-traded notes (ETNs), the securities of other investment companies, U.S. government securities, and other types of investments such as derivatives, including credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, in each case for the purposes of reducing risk, obtaining efficient market exposure, and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;To the extent legally permitted, the Board of Trustees of the fund may, in its discretion, determine to combine the fund with another fund without shareholder approval if the target allocation of the fund matches the target allocation of the other fund, although there is no assurance that the Board of Trustees will so determine at any point.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund bears its own expenses and, in addition, indirectly bears its proportionate share of the expenses of the underlying funds in which it invests. The fund's performance reflects both the managers' allocation decisions and the performance of the underlying funds.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Many factors affect performance, and fund shares will fluctuate in price, meaning you could lose money. The fund's investment strategy may not produce the intended results.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;During periods of heightened market volatility or reduced liquidity, governments, their agencies, or other regulatory bodies, both within the United States and abroad, may take steps to intervene. These actions, which could include legislative, regulatory, or economic initiatives, might have unforeseeable consequences and could adversely affect the fund's performance or otherwise constrain the fund's ability to achieve its investment objective.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in fixed-income securities than John Hancock Multi-Index Preservation Portfolios with target dates that are more distant, fixed-income securities risks are more prevalent in this fund than in these other target date funds. In addition to fixed-income securities risk, the fund's other main risk factors are listed below in alphabetical order. &lt;i&gt;Before investing, be sure to read the additional descriptions of these risks beginning on page 62 of the prospectus.&lt;/i&gt;

U.S. government securities are subject to varying degrees of credit risk based on the nature of their support.&lt;/div&gt;

               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;

Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;

However, at times, an ETF's portfolio composition and performance may not match that of such index.

The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;

               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;

               &lt;b&gt;Investment company securities risk.&lt;/b&gt; A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;

               &lt;b&gt;Lifecycle risk.&lt;/b&gt; Managers might not correctly predict market or economic conditions, and you could lose money even close to, during, or after the fund's designated retirement year.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Target allocation risk.&lt;/b&gt; The fund's risk profile will change due to reallocation or rebalancing of portfolio assets as the fund approaches its target date.&lt;/div&gt;

                &lt;i&gt;  Principal risks of investing in the underlying funds     &lt;/i&gt;          
               &lt;/b&gt;&lt;/div&gt;             
                     
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Short sales risk.&lt;/b&gt; Short sales involve costs and risk. A fund must pay the lender interest on the security it borrows, and the fund will lose money if the price of the security increases between the time of the short sale and the date when the fund replaces the borrowed security.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

The information shows how the fund's performance compares with the returns of an index of funds with similar investment objectives. From December 1, 2016 to November 30, 2017, the Custom Benchmark consisted of the following indices and approximate weightings: 12.60% Russell 3000 Index, 5.40% MSCI ACWI ex-USA Index, and 82.00% Bloomberg Barclays U.S. Aggregate Bond Index. The weightings of the indices in the Custom Benchmark are adjusted annually to reflect changes in the fund's target asset allocation in accordance with the annual roll-down of the glide path described above and differed in periods prior to December 1, 2016.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 14% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund primarily invests its assets in underlying funds using an asset allocation strategy designed for investors expected to retire around the year 2025.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The portfolio managers of the fund allocate assets among the underlying funds according to an asset allocation strategy that becomes increasingly conservative over time. John Hancock Multi-Index 2025 Preservation Portfolio has a target asset allocation of 32% of its assets in underlying funds that invest primarily in equity securities. The fund will have a greater exposure to underlying funds that invest primarily in fixed-income securities than will a John Hancock Multi-Index Preservation Portfolio with a more distant target date. To attempt to reduce investment risk and volatility as retirement approaches, the asset allocation strategy will change over time according to a predetermined glide path shown in the following chart.&lt;/div&gt;         
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                  GLIDE PATH CHART               
               &lt;/b&gt;&lt;/div&gt; 
&lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;/div&gt;             
                       &lt;img alt="glidepath chart" src="glidepath1.jpg"&gt;&lt;/img&gt;  
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The allocations reflected in the glide path are referred to as neutral because they do not reflect active decisions made by the portfolio managers to produce an overweight or an underweight position in a particular asset class. The fund has a target allocation to underlying funds that invest in the broad asset classes of equity and fixed-income securities but may also allocate its assets to underlying funds that invest outside these asset classes to protect the fund or help it achieve its objective. For example, the fund may also allocate its assets to underlying funds that invest in alternative and specialty asset classes. The investment advisor may change the target allocation without shareholder approval if it believes such change would benefit the fund and its shareholders. There is no guarantee that the managers will correctly predict the market or economic conditions. There is no guarantee that the fund will preserve either income or capital and, as with other mutual fund investments, you could lose money even if the fund is at or close to its designated retirement year. Under normal circumstances, any deviation from the target allocation is not expected to be greater than plus or minus 10%.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is designed for investors who anticipate reevaluating their retirement allocation strategies at the target date. Under normal market conditions, the fund expects to allocate 8% of its assets to equity underlying funds in its designated retirement year and to maintain that static allocation thereafter. This static allocation may be appropriate for some investors, but others may wish to reallocate their investments at retirement.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in underlying funds that invest in a broad range of equity, fixed-income, and alternative/specialty securities and asset classes, including, but not limited to, U.S. and foreign securities, including emerging-market securities, commodities, asset-backed securities, small-cap securities, and below-investment-grade securities (i.e., junk bonds). The underlying funds may also use derivatives, such as swaps, foreign currency forwards, futures, and options, in each case for the purposes of reducing risk, obtaining efficient market exposure and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund will invest in various passively managed underlying funds that as a group hold a wide range of equity-type securities in their portfolios, including convertible securities. The fund may also invest in various actively managed funds. The fund is not designed to track an index or group of indexes. Equity-type securities include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. Certain equity underlying funds may invest in initial public offerings (IPOs). Each of the equity underlying funds has its own investment strategy that, for example, may focus on growth stocks or value stocks, or may employ a strategy combining growth and income stocks, and/or may invest in derivatives such as credit default swaps, foreign currency forwards, interest rate swaps, options on securities, and futures contracts. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from shorter to longer term. The fixed-income underlying funds collectively hold various types of debt instruments such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging market securities). Certain underlying funds may invest in illiquid securities, and certain underlying funds may be non-diversified.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest directly in exchange-traded funds (ETFs), exchange-traded notes (ETNs), the securities of other investment companies, U.S. government securities, and other types of investments such as derivatives, including credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, in each case for the purposes of reducing risk, obtaining efficient market exposure, and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;To the extent legally permitted, the Board of Trustees of the fund may, in its discretion, determine to combine the fund with another fund without shareholder approval if the target allocation of the fund matches the target allocation of the other fund, although there is no assurance that the Board of Trustees will so determine at any point.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund bears its own expenses and, in addition, indirectly bears its proportionate share of the expenses of the underlying funds in which it invests. The fund's performance reflects both the managers' allocation decisions and the performance of the underlying funds.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Many factors affect performance, and fund shares will fluctuate in price, meaning you could lose money. The fund's investment strategy may not produce the intended results.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;During periods of heightened market volatility or reduced liquidity, governments, their agencies, or other regulatory bodies, both within the United States and abroad, may take steps to intervene. These actions, which could include legislative, regulatory, or economic initiatives, might have unforeseeable consequences and could adversely affect the fund's performance or otherwise constrain the fund's ability to achieve its investment objective.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in fixed-income securities than John Hancock Multi-Index Preservation Portfolios with target dates that are more distant, fixed-income securities risks are more prevalent in this fund than in these other target date funds. In addition to fixed-income securities risk, the fund's other main risk factors are listed below in alphabetical order. &lt;i&gt;Before investing, be sure to read the additional descriptions of these risks beginning on page 62 of the prospectus.&lt;/i&gt;            
            &lt;/div&gt;

                &lt;i&gt;  Principal risks of investing in the fund of funds  &lt;/i&gt;             
               &lt;/b&gt;&lt;/div&gt;

               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk based on the nature of their support.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Investment company securities risk.&lt;/b&gt; A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lifecycle risk.&lt;/b&gt; Managers might not correctly predict market or economic conditions, and you could lose money even close to, during, or after the fund's designated retirement year.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Target allocation risk.&lt;/b&gt; The fund's risk profile will change due to reallocation or rebalancing of portfolio assets as the fund approaches its target date.&lt;/div&gt;         
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
               &lt;i&gt;   Principal risks of investing in the underlying funds   &lt;/i&gt;            
               &lt;/b&gt;&lt;/div&gt;             
                     
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Short sales risk.&lt;/b&gt; Short sales involve costs and risk. A fund must pay the lender interest on the security it borrows, and the fund will lose money if the price of the security increases between the time of the short sale and the date when the fund replaces the borrowed security.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The following information illustrates the variability of the fund's returns and provides some indication of the risks of investing in the fund by showing changes in the fund's performance from year to year and by showing how the fund's average annual returns compared with a broad-based market index. Past performance (before and after taxes) does not indicate future results. All figures assume dividend reinvestment. Performance information is updated daily, monthly, and quarterly and may be obtained at our website, jhinvestments.com, or by calling 888-972-8696 between 8:30 A.M. and 5:00 P.M., Eastern time, on most business days.&lt;/div&gt;

               &lt;b&gt;Russell 3000 Index/MSCI ACWI ex-USA Index/Bloomberg Barclays U.S. Aggregate Bond Index&lt;/b&gt; This custom blended benchmark (Custom Benchmark) is based on the fund's asset allocation glide path shown above and will reflect a more conservative asset allocation over time. The information shows how the fund's performance compares with the returns of an index of funds with similar investment objectives. From December 1, 2016 to November 30, 2017, the Custom Benchmark consisted of the following indices and approximate weightings: 28.00% Russell 3000 Index, 12.00% MSCI ACWI ex-USA Index, and 60.00% Bloomberg Barclays U.S. Aggregate Bond Index. The weightings of the indices in the Custom Benchmark are adjusted annually to reflect changes in the fund's target asset allocation in accordance with the annual roll-down of the glide path described above and differed in periods prior to December 1, 2016.&lt;/div&gt;

Because Class R5 shares of the fund had not commenced operations as of the date of this prospectus, the returns shown are those of Class 1 shares. Returns for Class R5 shares would have been substantially similar to returns of Class 1 shares because each share class is invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.&lt;/div&gt;

Your actual after-tax returns may be different. After-tax returns are not relevant to shares held in an IRA, 401(k), or other tax-advantaged investment plan.&lt;/div&gt;

The example assumes a 5% average annual return and that fund expenses will not change over the periods.

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 18% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund primarily invests its assets in underlying funds using an asset allocation strategy designed for investors expected to retire around the year 2030.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The portfolio managers of the fund allocate assets among the underlying funds according to an asset allocation strategy that becomes increasingly conservative over time. John Hancock Multi-Index 2030 Preservation Portfolio has a target asset allocation of 51.50% of its assets in underlying funds that invest primarily in equity securities. The fund will have a greater exposure to underlying funds that invest primarily in equity securities than will a John Hancock Multi-Index Preservation Portfolio with a closer target date. To attempt to reduce investment risk and volatility as retirement approaches, the asset allocation strategy will change over time according to a predetermined glide path shown in the following chart.&lt;/div&gt;         
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                  GLIDE PATH CHART               
               &lt;/b&gt;&lt;/div&gt;             
        &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;/div&gt;              
                     &lt;img alt="glidepath chart" src="glidepath1.jpg"&gt;&lt;/img&gt; 
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The allocations reflected in the glide path are referred to as neutral because they do not reflect active decisions made by the portfolio managers to produce an overweight or an underweight position in a particular asset class. The fund has a target allocation to underlying funds that invest in the broad asset classes of equity and fixed-income securities but may also allocate its assets to underlying funds that invest outside these asset classes to protect the fund or help it achieve its objective. For example, the fund may also allocate its assets to underlying funds that invest in alternative and specialty asset classes. The investment advisor may change the target allocation without shareholder approval if it believes such change would benefit the fund and its shareholders. There is no guarantee that the managers will correctly predict the market or economic conditions. There is no guarantee that the fund will preserve either income or capital and, as with other mutual fund investments, you could lose money even if the fund is at or close to its designated retirement year. Under normal circumstances, any deviation from the target allocation is not expected to be greater than plus or minus 10%.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is designed for investors who anticipate reevaluating their retirement allocation strategies at the target date. Under normal market conditions, the fund expects to allocate 8% of its assets to equity underlying funds in its designated retirement year and to maintain that static allocation thereafter. This static allocation may be appropriate for some investors, but others may wish to reallocate their investments at retirement.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in underlying funds that invest in a broad range of equity, fixed-income, and alternative/specialty securities and asset classes, including, but not limited to, U.S. and foreign securities, including emerging-market securities, commodities, asset-backed securities, small-cap securities, and below-investment-grade securities (i.e., junk bonds). The underlying funds may also use derivatives, such as swaps, foreign currency forwards, futures, and options, in each case for the purposes of reducing risk, obtaining efficient market exposure and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund will invest in various passively managed underlying funds that as a group hold a wide range of equity-type securities in their portfolios, including convertible securities. The fund may also invest in various actively managed funds. The fund is not designed to track an index or group of indexes. Equity-type securities include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. Certain equity underlying funds may invest in initial public offerings (IPOs). Each of the equity underlying funds has its own investment strategy that, for example, may focus on growth stocks or value stocks, or may employ a strategy combining growth and income stocks, and/or may invest in derivatives such as credit default swaps, foreign currency forwards, interest rate swaps, options on securities, and futures contracts. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from shorter to longer term. The fixed-income underlying funds collectively hold various types of debt instruments such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging market securities). Certain underlying funds may invest in illiquid securities, and certain underlying funds may be non-diversified.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest directly in exchange-traded funds (ETFs), exchange-traded notes (ETNs), the securities of other investment companies, U.S. government securities, and other types of investments such as derivatives, including credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, in each case for the purposes of reducing risk, obtaining efficient market exposure, and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;To the extent legally permitted, the Board of Trustees of the fund may, in its discretion, determine to combine the fund with another fund without shareholder approval if the target allocation of the fund matches the target allocation of the other fund, although there is no assurance that the Board of Trustees will so determine at any point.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund bears its own expenses and, in addition, indirectly bears its proportionate share of the expenses of the underlying funds in which it invests. The fund's performance reflects both the managers' allocation decisions and the performance of the underlying funds.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Many factors affect performance, and fund shares will fluctuate in price, meaning you could lose money. The fund's investment strategy may not produce the intended results.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;During periods of heightened market volatility or reduced liquidity, governments, their agencies, or other regulatory bodies, both within the United States and abroad, may take steps to intervene. These actions, which could include legislative, regulatory, or economic initiatives, might have unforeseeable consequences and could adversely affect the fund's performance or otherwise constrain the fund's ability to achieve its investment objective.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in equity securities than John Hancock Multi-Index Preservation Portfolios with closer target dates, equity security risks are more prevalent in this fund than in these other target-date funds. In addition to equity securities risk, the fund's other main risk factors are listed below in alphabetical order. &lt;i&gt;Before investing, be sure to read the additional descriptions of these risks beginning on page 62 of the prospectus.&lt;/i&gt;            
            &lt;/div&gt;

               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk based on the nature of their support.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;

               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;

               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;

               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;

               &lt;b&gt;Target allocation risk.&lt;/b&gt; The fund's risk profile will change due to reallocation or rebalancing of portfolio assets as the fund approaches its target date.&lt;/div&gt;

               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality.

Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment.

Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;

               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;

               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;

               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;

               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;

               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Short sales risk.&lt;/b&gt; Short sales involve costs and risk. A fund must pay the lender interest on the security it borrows, and the fund will lose money if the price of the security increases between the time of the short sale and the date when the fund replaces the borrowed security.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The following information illustrates the variability of the fund's returns and provides some indication of the risks of investing in the fund by showing changes in the fund's performance from year to year and by showing how the fund's average annual returns compared with a broad-based market index. Past performance (before and after taxes) does not indicate future results. All figures assume dividend reinvestment. Performance information is updated daily, monthly, and quarterly and may be obtained at our website, jhinvestments.com, or by calling 888-972-8696 between 8:30 A.M. and 5:00 P.M., Eastern time, on most business days.&lt;/div&gt;

               &lt;b&gt;Russell 3000 Index/MSCI ACWI ex-USA Index/Bloomberg Barclays U.S. Aggregate Bond Index&lt;/b&gt; This custom blended benchmark (Custom Benchmark) is based on the fund's asset allocation glide path shown above and will reflect a more conservative asset allocation over time. The information shows how the fund's performance compares with the returns of an index of funds with similar investment objectives. From December 1, 2016 to November 30, 2017, the Custom Benchmark consisted of the following indices and approximate weightings: 41.30% Russell 3000 Index, 17.70% MSCI ACWI ex-USA Index, and 41.00% Bloomberg Barclays U.S. Aggregate Bond Index. The weightings of the indices in the Custom Benchmark are adjusted annually to reflect changes in the fund's target asset allocation in accordance with the annual roll-down of the glide path described above and differed in periods prior to December 1, 2016.&lt;/div&gt;

Because Class R5 shares of the fund had not commenced operations as of the date of this prospectus, the returns shown are those of Class 1 shares. Returns for Class R5 shares would have been substantially similar to returns of Class 1 shares because each share class is invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 17% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund primarily invests its assets in underlying funds using an asset allocation strategy designed for investors expected to retire around the year 2035.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The portfolio managers of the fund allocate assets among the underlying funds according to an asset allocation strategy that becomes increasingly conservative over time. John Hancock Multi-Index 2035 Preservation Portfolio has a target asset allocation of 67% of its assets in underlying funds that invest primarily in equity securities. The fund will have a greater exposure to underlying funds that invest primarily in equity securities than will a John Hancock Multi-Index Preservation Portfolio with a closer target date. To attempt to reduce investment risk and volatility as retirement approaches, the asset allocation strategy will change over time according to a predetermined glide path shown in the following chart.&lt;/div&gt;         
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                  GLIDE PATH CHART               
               &lt;/b&gt;&lt;/div&gt;  
&lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;/div&gt;            
                        &lt;img alt="glidepath chart" src="glidepath1.jpg"&gt;&lt;/img&gt; 
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The allocations reflected in the glide path are referred to as neutral because they do not reflect active decisions made by the portfolio managers to produce an overweight or an underweight position in a particular asset class. The fund has a target allocation to underlying funds that invest in the broad asset classes of equity and fixed-income securities but may also allocate its assets to underlying funds that invest outside these asset classes to protect the fund or help it achieve its objective. For example, the fund may also allocate its assets to underlying funds that invest in alternative and specialty asset classes. The investment advisor may change the target allocation without shareholder approval if it believes such change would benefit the fund and its shareholders. There is no guarantee that the managers will correctly predict the market or economic conditions. There is no guarantee that the fund will preserve either income or capital and, as with other mutual fund investments, you could lose money even if the fund is at or close to its designated retirement year. Under normal circumstances, any deviation from the target allocation is not expected to be greater than plus or minus 10%.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is designed for investors who anticipate reevaluating their retirement allocation strategies at the target date. Under normal market conditions, the fund expects to allocate 8% of its assets to equity underlying funds in its designated retirement year and to maintain that static allocation thereafter. This static allocation may be appropriate for some investors, but others may wish to reallocate their investments at retirement.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in underlying funds that invest in a broad range of equity, fixed-income, and alternative/specialty securities and asset classes, including, but not limited to, U.S. and foreign securities, including emerging-market securities, commodities, asset-backed securities, small-cap securities, and below-investment-grade securities (i.e., junk bonds). The underlying funds may also use derivatives, such as swaps, foreign currency forwards, futures, and options, in each case for the purposes of reducing risk, obtaining efficient market exposure and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund will invest in various passively managed underlying funds that as a group hold a wide range of equity-type securities in their portfolios, including convertible securities. The fund may also invest in various actively managed funds. The fund is not designed to track an index or group of indexes. Equity-type securities include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. Certain equity underlying funds may invest in initial public offerings (IPOs). Each of the equity underlying funds has its own investment strategy that, for example, may focus on growth stocks or value stocks, or may employ a strategy combining growth and income stocks, and/or may invest in derivatives such as credit default swaps, foreign currency forwards, interest rate swaps, options on securities, and futures contracts. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from shorter to longer term. The fixed-income underlying funds collectively hold various types of debt instruments such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging market securities). Certain underlying funds may invest in illiquid securities, and certain underlying funds may be non-diversified.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest directly in exchange-traded funds (ETFs), exchange-traded notes (ETNs), the securities of other investment companies, U.S. government securities, and other types of investments such as derivatives, including credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, in each case for the purposes of reducing risk, obtaining efficient market exposure, and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;To the extent legally permitted, the Board of Trustees of the fund may, in its discretion, determine to combine the fund with another fund without shareholder approval if the target allocation of the fund matches the target allocation of the other fund, although there is no assurance that the Board of Trustees will so determine at any point.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund bears its own expenses and, in addition, indirectly bears its proportionate share of the expenses of the underlying funds in which it invests. The fund's performance reflects both the managers' allocation decisions and the performance of the underlying funds.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Many factors affect performance, and fund shares will fluctuate in price, meaning you could lose money. The fund's investment strategy may not produce the intended results.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;During periods of heightened market volatility or reduced liquidity, governments, their agencies, or other regulatory bodies, both within the United States and abroad, may take steps to intervene. These actions, which could include legislative, regulatory, or economic initiatives, might have unforeseeable consequences and could adversely affect the fund's performance or otherwise constrain the fund's ability to achieve its investment objective.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in equity securities than John Hancock Multi-Index Preservation Portfolios with closer target dates, equity security risks are more prevalent in this fund than in these other target-date funds. In addition to equity securities risk, the fund's other main risk factors are listed below in alphabetical order. &lt;i&gt;Before investing, be sure to read the additional descriptions of these risks beginning on page 62 of the prospectus.&lt;/i&gt;

               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk based on the nature of their support.&lt;/div&gt;

               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;

               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;

               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;

               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;

               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;

               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;

               &lt;/b&gt;&lt;/div&gt;

               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Short sales risk.&lt;/b&gt; Short sales involve costs and risk. A fund must pay the lender interest on the security it borrows, and the fund will lose money if the price of the security increases between the time of the short sale and the date when the fund replaces the borrowed security.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The following information illustrates the variability of the fund's returns and provides some indication of the risks of investing in the fund by showing changes in the fund's performance from year to year and by showing how the fund's average annual returns compared with a broad-based market index.

The information shows how the fund's performance compares with the returns of an index of funds with similar investment objectives. From December 1, 2016 to November 30, 2017, the Custom Benchmark consisted of the following indices and approximate weightings: 49.70% Russell 3000 Index, 21.30% MSCI ACWI ex-USA Index, and 29.00% Bloomberg Barclays U.S. Aggregate Bond Index. The weightings of the indices in the Custom Benchmark are adjusted annually to reflect changes in the fund's target asset allocation in accordance with the annual roll-down of the glide path described above and differed in periods prior to December 1, 2016.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 16% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund primarily invests its assets in underlying funds using an asset allocation strategy designed for investors expected to retire around the year 2040.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The portfolio managers of the fund allocate assets among the underlying funds according to an asset allocation strategy that becomes increasingly conservative over time. John Hancock Multi-Index 2040 Preservation Portfolio has a target asset allocation of 75.50% of its assets in underlying funds that invest primarily in equity securities. The fund will have a greater exposure to underlying funds that invest primarily in equity securities than will a John Hancock Multi-Index Preservation Portfolio with a closer target date. To attempt to reduce investment risk and volatility as retirement approaches, the asset allocation strategy will change over time according to a predetermined glide path shown in the following chart.&lt;/div&gt;         
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                  GLIDE PATH CHART               
               &lt;/b&gt;&lt;/div&gt;             
        &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;/div&gt;              
                     &lt;img alt="glidepath chart" src="glidepath1.jpg"&gt;&lt;/img&gt; 
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The allocations reflected in the glide path are referred to as neutral because they do not reflect active decisions made by the portfolio managers to produce an overweight or an underweight position in a particular asset class. The fund has a target allocation to underlying funds that invest in the broad asset classes of equity and fixed-income securities but may also allocate its assets to underlying funds that invest outside these asset classes to protect the fund or help it achieve its objective. For example, the fund may also allocate its assets to underlying funds that invest in alternative and specialty asset classes. The investment advisor may change the target allocation without shareholder approval if it believes such change would benefit the fund and its shareholders. There is no guarantee that the managers will correctly predict the market or economic conditions. There is no guarantee that the fund will preserve either income or capital and, as with other mutual fund investments, you could lose money even if the fund is at or close to its designated retirement year. Under normal circumstances, any deviation from the target allocation is not expected to be greater than plus or minus 10%.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is designed for investors who anticipate reevaluating their retirement allocation strategies at the target date. Under normal market conditions, the fund expects to allocate 8% of its assets to equity underlying funds in its designated retirement year and to maintain that static allocation thereafter. This static allocation may be appropriate for some investors, but others may wish to reallocate their investments at retirement.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in underlying funds that invest in a broad range of equity, fixed-income, and alternative/specialty securities and asset classes, including, but not limited to, U.S. and foreign securities, including emerging-market securities, commodities, asset-backed securities, small-cap securities, and below-investment-grade securities (i.e., junk bonds). The underlying funds may also use derivatives, such as swaps, foreign currency forwards, futures, and options, in each case for the purposes of reducing risk, obtaining efficient market exposure and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund will invest in various passively managed underlying funds that as a group hold a wide range of equity-type securities in their portfolios, including convertible securities. The fund may also invest in various actively managed funds. The fund is not designed to track an index or group of indexes. Equity-type securities include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. Certain equity underlying funds may invest in initial public offerings (IPOs). Each of the equity underlying funds has its own investment strategy that, for example, may focus on growth stocks or value stocks, or may employ a strategy combining growth and income stocks, and/or may invest in derivatives such as credit default swaps, foreign currency forwards, interest rate swaps, options on securities, and futures contracts. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from shorter to longer term. The fixed-income underlying funds collectively hold various types of debt instruments such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging market securities). Certain underlying funds may invest in illiquid securities, and certain underlying funds may be non-diversified.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest directly in exchange-traded funds (ETFs), exchange-traded notes (ETNs), the securities of other investment companies, U.S. government securities, and other types of investments such as derivatives, including credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, in each case for the purposes of reducing risk, obtaining efficient market exposure, and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;To the extent legally permitted, the Board of Trustees of the fund may, in its discretion, determine to combine the fund with another fund without shareholder approval if the target allocation of the fund matches the target allocation of the other fund, although there is no assurance that the Board of Trustees will so determine at any point.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund bears its own expenses and, in addition, indirectly bears its proportionate share of the expenses of the underlying funds in which it invests. The fund's performance reflects both the managers' allocation decisions and the performance of the underlying funds.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Many factors affect performance, and fund shares will fluctuate in price, meaning you could lose money. The fund's investment strategy may not produce the intended results.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;During periods of heightened market volatility or reduced liquidity, governments, their agencies, or other regulatory bodies, both within the United States and abroad, may take steps to intervene. These actions, which could include legislative, regulatory, or economic initiatives, might have unforeseeable consequences and could adversely affect the fund's performance or otherwise constrain the fund's ability to achieve its investment objective.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in equity securities than John Hancock Multi-Index Preservation Portfolios with closer target dates, equity security risks are more prevalent in this fund than in these other target-date funds.

               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk based on the nature of their support.&lt;/div&gt;

Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;

               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;

               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;

               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;

               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;

               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Investment company securities risk.&lt;/b&gt; A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lifecycle risk.&lt;/b&gt; Managers might not correctly predict market or economic conditions, and you could lose money even close to, during, or after the fund's designated retirement year.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Target allocation risk.&lt;/b&gt; The fund's risk profile will change due to reallocation or rebalancing of portfolio assets as the fund approaches its target date.&lt;/div&gt;

               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality.

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide.

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment.

Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Short sales risk.&lt;/b&gt; Short sales involve costs and risk. A fund must pay the lender interest on the security it borrows, and the fund will lose money if the price of the security increases between the time of the short sale and the date when the fund replaces the borrowed security.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

The information shows how the fund's performance compares with the returns of an index of funds with similar investment objectives. From December 1, 2016 to November 30, 2017, the Custom Benchmark consisted of the following indices and approximate weightings: 54.60% Russell 3000 Index, 23.40% MSCI ACWI ex-USA Index, and 22.00% Bloomberg Barclays U.S. Aggregate Bond Index. The weightings of the indices in the Custom Benchmark are adjusted annually to reflect changes in the fund's target asset allocation in accordance with the annual roll-down of the glide path described above and differed in periods prior to December 1, 2016.&lt;/div&gt;

Returns for Class R5 shares would have been substantially similar to returns of Class 1 shares because each share class is invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.&lt;/div&gt;

Your actual after-tax returns may be different. After-tax returns are not relevant to shares held in an IRA, 401(k), or other tax-advantaged investment plan.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 12% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund primarily invests its assets in underlying funds using an asset allocation strategy designed for investors expected to retire around the year 2045.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The portfolio managers of the fund allocate assets among the underlying funds according to an asset allocation strategy that becomes increasingly conservative over time. John Hancock Multi-Index 2045 Preservation Portfolio has a target asset allocation of 80.50% of its assets in underlying funds that invest primarily in equity securities. The fund will have a greater exposure to underlying funds that invest primarily in equity securities than will a John Hancock Multi-Index Preservation Portfolio with a closer target date. To attempt to reduce investment risk and volatility as retirement approaches, the asset allocation strategy will change over time according to a predetermined glide path shown in the following chart.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The allocations reflected in the glide path are referred to as neutral because they do not reflect active decisions made by the portfolio managers to produce an overweight or an underweight position in a particular asset class. The fund has a target allocation to underlying funds that invest in the broad asset classes of equity and fixed-income securities but may also allocate its assets to underlying funds that invest outside these asset classes to protect the fund or help it achieve its objective. For example, the fund may also allocate its assets to underlying funds that invest in alternative and specialty asset classes. The investment advisor may change the target allocation without shareholder approval if it believes such change would benefit the fund and its shareholders. There is no guarantee that the managers will correctly predict the market or economic conditions. There is no guarantee that the fund will preserve either income or capital and, as with other mutual fund investments, you could lose money even if the fund is at or close to its designated retirement year. Under normal circumstances, any deviation from the target allocation is not expected to be greater than plus or minus 10%.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is designed for investors who anticipate reevaluating their retirement allocation strategies at the target date. Under normal market conditions, the fund expects to allocate 8% of its assets to equity underlying funds in its designated retirement year and to maintain that static allocation thereafter. This static allocation may be appropriate for some investors, but others may wish to reallocate their investments at retirement.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in underlying funds that invest in a broad range of equity, fixed-income, and alternative/specialty securities and asset classes, including, but not limited to, U.S. and foreign securities, including emerging-market securities, commodities, asset-backed securities, small-cap securities, and below-investment-grade securities (i.e., junk bonds). The underlying funds may also use derivatives, such as swaps, foreign currency forwards, futures, and options, in each case for the purposes of reducing risk, obtaining efficient market exposure and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund will invest in various passively managed underlying funds that as a group hold a wide range of equity-type securities in their portfolios, including convertible securities. The fund may also invest in various actively managed funds. The fund is not designed to track an index or group of indexes. Equity-type securities include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. Certain equity underlying funds may invest in initial public offerings (IPOs). Each of the equity underlying funds has its own investment strategy that, for example, may focus on growth stocks or value stocks, or may employ a strategy combining growth and income stocks, and/or may invest in derivatives such as credit default swaps, foreign currency forwards, interest rate swaps, options on securities, and futures contracts. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from shorter to longer term. The fixed-income underlying funds collectively hold various types of debt instruments such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging market securities). Certain underlying funds may invest in illiquid securities, and certain underlying funds may be non-diversified.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest directly in exchange-traded funds (ETFs), exchange-traded notes (ETNs), the securities of other investment companies, U.S. government securities, and other types of investments such as derivatives, including credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, in each case for the purposes of reducing risk, obtaining efficient market exposure, and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;To the extent legally permitted, the Board of Trustees of the fund may, in its discretion, determine to combine the fund with another fund without shareholder approval if the target allocation of the fund matches the target allocation of the other fund, although there is no assurance that the Board of Trustees will so determine at any point.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund bears its own expenses and, in addition, indirectly bears its proportionate share of the expenses of the underlying funds in which it invests. The fund's performance reflects both the managers' allocation decisions and the performance of the underlying funds.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Many factors affect performance, and fund shares will fluctuate in price, meaning you could lose money. The fund's investment strategy may not produce the intended results.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;During periods of heightened market volatility or reduced liquidity, governments, their agencies, or other regulatory bodies, both within the United States and abroad, may take steps to intervene. These actions, which could include legislative, regulatory, or economic initiatives, might have unforeseeable consequences and could adversely affect the fund's performance or otherwise constrain the fund's ability to achieve its investment objective.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in equity securities than John Hancock Multi-Index Preservation Portfolios with closer target dates, equity security risks are more prevalent in this fund than in these other target-date funds. In addition to equity securities risk, the fund's other main risk factors are listed below in alphabetical order. &lt;i&gt;Before investing, be sure to read the additional descriptions of these risks beginning on page 62 of the prospectus.&lt;/i&gt;            
            &lt;/div&gt;

               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk based on the nature of their support.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;

               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;

               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;

               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;

               &lt;b&gt;Target allocation risk.&lt;/b&gt; The fund's risk profile will change due to reallocation or rebalancing of portfolio assets as the fund approaches its target date.&lt;/div&gt;

               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;

               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;

               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;

               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;

               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;

               &lt;b&gt;Short sales risk.&lt;/b&gt; Short sales involve costs and risk. A fund must pay the lender interest on the security it borrows, and the fund will lose money if the price of the security increases between the time of the short sale and the date when the fund replaces the borrowed security.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The following information illustrates the variability of the fund's returns and provides some indication of the risks of investing in the fund by showing changes in the fund's performance from year to year and by showing how the fund's average annual returns compared with a broad-based market index. Past performance (before and after taxes) does not indicate future results. All figures assume dividend reinvestment. Performance information is updated daily, monthly, and quarterly and may be obtained at our website, jhinvestments.com, or by calling 888-972-8696 between 8:30 A.M. and 5:00 P.M., Eastern time, on most business days.&lt;/div&gt;

               &lt;b&gt;Russell 3000 Index/MSCI ACWI ex-USA Index/Bloomberg Barclays U.S. Aggregate Bond Index&lt;/b&gt; This custom blended benchmark (Custom Benchmark) is based on the fund's asset allocation glide path shown above and will reflect a more conservative asset allocation over time. The information shows how the fund's performance compares with the returns of an index of funds with similar investment objectives. From December 1, 2016 to November 30, 2017, the Custom Benchmark consisted of the following indices and approximate weightings: 57.05% Russell 3000 Index, 24.45% MSCI ACWI ex-USA Index, and 18.50% Bloomberg Barclays U.S. Aggregate Bond Index. The weightings of the indices in the Custom Benchmark are adjusted annually to reflect changes in the fund's target asset allocation in accordance with the annual roll-down of the glide path described above.&lt;/div&gt;

Because Class R5 shares of the fund had not commenced operations as of the date of this prospectus, the returns shown are those of Class 1 shares. Returns for Class R5 shares would have been substantially similar to returns of Class 1 shares because each share class is invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.&lt;/div&gt;

Your actual after-tax returns may be different. After-tax returns are not relevant to shares held in an IRA, 401(k), or other tax-advantaged investment plan.&lt;/div&gt;

Please see below a hypothetical example showing the expenses of a $10,000 investment for the time periods indicated and then assuming you sell all of your shares at the end of those periods. The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 13% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund primarily invests its assets in underlying funds using an asset allocation strategy designed for investors expected to retire around the year 2050.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The portfolio managers of the fund allocate assets among the underlying funds according to an asset allocation strategy that becomes increasingly conservative over time. John Hancock Multi-Index 2050 Preservation Portfolio has a target asset allocation of 82% of its assets in underlying funds that invest primarily in equity securities. The fund will have a greater exposure to underlying funds that invest primarily in equity securities than will a John Hancock Multi-Index Preservation Portfolio with a closer target date. To attempt to reduce investment risk and volatility as retirement approaches, the asset allocation strategy will change over time according to a predetermined glide path shown in the following chart.&lt;/div&gt;          
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                  GLIDE PATH CHART               
               &lt;/b&gt;&lt;/div&gt;        
&lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;/div&gt;      
                        &lt;img alt="glidepath chart" src="glidepath1.jpg"&gt;&lt;/img&gt; 
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The allocations reflected in the glide path are referred to as neutral because they do not reflect active decisions made by the portfolio managers to produce an overweight or an underweight position in a particular asset class. The fund has a target allocation to underlying funds that invest in the broad asset classes of equity and fixed-income securities but may also allocate its assets to underlying funds that invest outside these asset classes to protect the fund or help it achieve its objective. For example, the fund may also allocate its assets to underlying funds that invest in alternative and specialty asset classes. The investment advisor may change the target allocation without shareholder approval if it believes such change would benefit the fund and its shareholders. There is no guarantee that the managers will correctly predict the market or economic conditions. There is no guarantee that the fund will preserve either income or capital and, as with other mutual fund investments, you could lose money even if the fund is at or close to its designated retirement year. Under normal circumstances, any deviation from the target allocation is not expected to be greater than plus or minus 10%.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is designed for investors who anticipate reevaluating their retirement allocation strategies at the target date. Under normal market conditions, the fund expects to allocate 8% of its assets to equity underlying funds in its designated retirement year and to maintain that static allocation thereafter. This static allocation may be appropriate for some investors, but others may wish to reallocate their investments at retirement.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in underlying funds that invest in a broad range of equity, fixed-income, and alternative/specialty securities and asset classes, including, but not limited to, U.S. and foreign securities, including emerging-market securities, commodities, asset-backed securities, small-cap securities, and below-investment-grade securities (i.e., junk bonds). The underlying funds may also use derivatives, such as swaps, foreign currency forwards, futures, and options, in each case for the purposes of reducing risk, obtaining efficient market exposure and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund will invest in various passively managed underlying funds that as a group hold a wide range of equity-type securities in their portfolios, including convertible securities. The fund may also invest in various actively managed funds. The fund is not designed to track an index or group of indexes. Equity-type securities include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. Certain equity underlying funds may invest in initial public offerings (IPOs). Each of the equity underlying funds has its own investment strategy that, for example, may focus on growth stocks or value stocks, or may employ a strategy combining growth and income stocks, and/or may invest in derivatives such as credit default swaps, foreign currency forwards, interest rate swaps, options on securities, and futures contracts. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from shorter to longer term. The fixed-income underlying funds collectively hold various types of debt instruments such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging market securities). Certain underlying funds may invest in illiquid securities, and certain underlying funds may be non-diversified.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest directly in exchange-traded funds (ETFs), exchange-traded notes (ETNs), the securities of other investment companies, U.S. government securities, and other types of investments such as derivatives, including credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, in each case for the purposes of reducing risk, obtaining efficient market exposure, and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;To the extent legally permitted, the Board of Trustees of the fund may, in its discretion, determine to combine the fund with another fund without shareholder approval if the target allocation of the fund matches the target allocation of the other fund, although there is no assurance that the Board of Trustees will so determine at any point.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund bears its own expenses and, in addition, indirectly bears its proportionate share of the expenses of the underlying funds in which it invests. The fund's performance reflects both the managers' allocation decisions and the performance of the underlying funds.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Many factors affect performance, and fund shares will fluctuate in price, meaning you could lose money. The fund's investment strategy may not produce the intended results.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;During periods of heightened market volatility or reduced liquidity, governments, their agencies, or other regulatory bodies, both within the United States and abroad, may take steps to intervene. These actions, which could include legislative, regulatory, or economic initiatives, might have unforeseeable consequences and could adversely affect the fund's performance or otherwise constrain the fund's ability to achieve its investment objective.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in equity securities than John Hancock Multi-Index Preservation Portfolios with closer target dates, equity security risks are more prevalent in this fund than in these other target-date funds. In addition to equity securities risk, the fund's other main risk factors are listed below in alphabetical order. &lt;i&gt;Before investing, be sure to read the additional descriptions of these risks beginning on page 62 of the prospectus.&lt;/i&gt;

               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk based on the nature of their support.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;

               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;

               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;

               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;

               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;

               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;

               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;

               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;

               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;

Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Short sales risk.&lt;/b&gt; Short sales involve costs and risk. A fund must pay the lender interest on the security it borrows, and the fund will lose money if the price of the security increases between the time of the short sale and the date when the fund replaces the borrowed security.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

The information shows how the fund's performance compares with the returns of an index of funds with similar investment objectives. From April 29, 2011 to November 30, 2017, the Custom Benchmark consisted of the following indices and approximate weightings: 57.40% Russell 3000 Index, 24.60% MSCI ACWI ex-USA Index, and 18.00% Bloomberg Barclays U.S. Aggregate Bond Index. The weightings of the indices in the Custom Benchmark are adjusted annually to reflect changes in the fund's target asset allocation in accordance with the annual roll-down of the glide path described above.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 10% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund primarily invests its assets in underlying funds using an asset allocation strategy designed for investors expected to retire around the year 2055.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The portfolio managers of the fund allocate assets among the underlying funds according to an asset allocation strategy that becomes increasingly conservative over time. John Hancock Multi-Index 2055 Preservation Portfolio has a target asset allocation of 82% of its assets in underlying funds that invest primarily in equity securities. The fund will have a greater exposure to underlying funds that invest primarily in equity securities than will a John Hancock Multi-Index Preservation Portfolio with a closer target date. To attempt to reduce investment risk and volatility as retirement approaches, the asset allocation strategy will change over time according to a predetermined glide path shown in the following chart.&lt;/div&gt;          
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                  GLIDE PATH CHART               
               &lt;/b&gt;&lt;/div&gt;             
      &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;/div&gt;                
                     &lt;img alt="glidepath chart" src="glidepath1.jpg"&gt;&lt;/img&gt; 
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The allocations reflected in the glide path are referred to as neutral because they do not reflect active decisions made by the portfolio managers to produce an overweight or an underweight position in a particular asset class. The fund has a target allocation to underlying funds that invest in the broad asset classes of equity and fixed-income securities but may also allocate its assets to underlying funds that invest outside these asset classes to protect the fund or help it achieve its objective. For example, the fund may also allocate its assets to underlying funds that invest in alternative and specialty asset classes. The investment advisor may change the target allocation without shareholder approval if it believes such change would benefit the fund and its shareholders. There is no guarantee that the managers will correctly predict the market or economic conditions. There is no guarantee that the fund will preserve either income or capital and, as with other mutual fund investments, you could lose money even if the fund is at or close to its designated retirement year. Under normal circumstances, any deviation from the target allocation is not expected to be greater than plus or minus 10%.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is designed for investors who anticipate reevaluating their retirement allocation strategies at the target date. Under normal market conditions, the fund expects to allocate 8% of its assets to equity underlying funds in its designated retirement year and to maintain that static allocation thereafter. This static allocation may be appropriate for some investors, but others may wish to reallocate their investments at retirement.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in underlying funds that invest in a broad range of equity, fixed-income, and alternative/specialty securities and asset classes, including, but not limited to, U.S. and foreign securities, including emerging-market securities, commodities, asset-backed securities, small-cap securities, and below-investment-grade securities (i.e., junk bonds). The underlying funds may also use derivatives, such as swaps, foreign currency forwards, futures, and options, in each case for the purposes of reducing risk, obtaining efficient market exposure and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund will invest in various passively managed underlying funds that as a group hold a wide range of equity-type securities in their portfolios, including convertible securities. The fund may also invest in various actively managed funds. The fund is not designed to track an index or group of indexes. Equity-type securities include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. Certain equity underlying funds may invest in initial public offerings (IPOs). Each of the equity underlying funds has its own investment strategy that, for example, may focus on growth stocks or value stocks, or may employ a strategy combining growth and income stocks, and/or may invest in derivatives such as credit default swaps, foreign currency forwards, interest rate swaps, options on securities, and futures contracts. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from shorter to longer term. The fixed-income underlying funds collectively hold various types of debt instruments such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging market securities). Certain underlying funds may invest in illiquid securities, and certain underlying funds may be non-diversified.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest directly in exchange-traded funds (ETFs), exchange-traded notes (ETNs), the securities of other investment companies, U.S. government securities, and other types of investments such as derivatives, including credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, in each case for the purposes of reducing risk, obtaining efficient market exposure, and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;To the extent legally permitted, the Board of Trustees of the fund may, in its discretion, determine to combine the fund with another fund without shareholder approval if the target allocation of the fund matches the target allocation of the other fund, although there is no assurance that the Board of Trustees will so determine at any point.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund bears its own expenses and, in addition, indirectly bears its proportionate share of the expenses of the underlying funds in which it invests. The fund's performance reflects both the managers' allocation decisions and the performance of the underlying funds.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Many factors affect performance, and fund shares will fluctuate in price, meaning you could lose money. The fund's investment strategy may not produce the intended results.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;During periods of heightened market volatility or reduced liquidity, governments, their agencies, or other regulatory bodies, both within the United States and abroad, may take steps to intervene. These actions, which could include legislative, regulatory, or economic initiatives, might have unforeseeable consequences and could adversely affect the fund's performance or otherwise constrain the fund's ability to achieve its investment objective.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in equity securities than John Hancock Multi-Index Preservation Portfolios with closer target dates, equity security risks are more prevalent in this fund than in these other target-date funds. In addition to equity securities risk, the fund's other main risk factors are listed below in alphabetical order. &lt;i&gt;Before investing, be sure to read the additional descriptions of these risks beginning on page 62 of the prospectus.&lt;/i&gt;

U.S. government securities are subject to varying degrees of credit risk based on the nature of their support.&lt;/div&gt;

               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;

Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;

ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Investment company securities risk.&lt;/b&gt; A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;

               &lt;b&gt;Lifecycle risk.&lt;/b&gt; Managers might not correctly predict market or economic conditions, and you could lose money even close to, during, or after the fund's designated retirement year.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Target allocation risk.&lt;/b&gt; The fund's risk profile will change due to reallocation or rebalancing of portfolio assets as the fund approaches its target date.&lt;/div&gt;         
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                &lt;i&gt;  Principal risks of investing in the underlying funds &lt;/i&gt;              
               &lt;/b&gt;&lt;/div&gt;             
                     
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Short sales risk.&lt;/b&gt; Short sales involve costs and risk. A fund must pay the lender interest on the security it borrows, and the fund will lose money if the price of the security increases between the time of the short sale and the date when the fund replaces the borrowed security.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

The information shows how the fund's performance compares with the returns of an index of funds with similar investment objectives. From March 26, 2014 to November 30, 2017, the Custom Benchmark consisted of the following indices and approximate weightings: 57.40% Russell 3000 Index, 24.60% MSCI ACWI ex-USA Index, and 18.00% Bloomberg Barclays U.S. Aggregate Bond Index. The weightings of the indices in the Custom Benchmark are adjusted annually to reflect changes in the fund's target asset allocation in accordance with the annual roll-down of the glide path described above.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 10% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund primarily invests its assets in underlying funds using an asset allocation strategy designed for investors expected to retire around the year 2060.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The portfolio managers of the fund allocate assets among the underlying funds according to an asset allocation strategy that becomes increasingly conservative over time. John Hancock Multi-Index 2060 Preservation Portfolio has a target asset allocation of 82% of its assets in underlying funds that invest primarily in equity securities. The fund will have a greater exposure to underlying funds that invest primarily in equity securities than will a John Hancock Multi-Index Preservation Portfolio with a closer target date. To attempt to reduce investment risk and volatility as retirement approaches, the asset allocation strategy will change over time according to a predetermined glide path shown in the following chart.&lt;/div&gt;          
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                  GLIDE PATH CHART               
               &lt;/b&gt;&lt;/div&gt;   
&lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;/div&gt;           
                        &lt;img alt="glidepath chart" src="glidepath1.jpg"&gt;&lt;/img&gt; 
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The allocations reflected in the glide path are referred to as neutral because they do not reflect active decisions made by the portfolio managers to produce an overweight or an underweight position in a particular asset class. The fund has a target allocation to underlying funds that invest in the broad asset classes of equity and fixed-income securities but may also allocate its assets to underlying funds that invest outside these asset classes to protect the fund or help it achieve its objective. For example, the fund may also allocate its assets to underlying funds that invest in alternative and specialty asset classes. The investment advisor may change the target allocation without shareholder approval if it believes such change would benefit the fund and its shareholders. There is no guarantee that the managers will correctly predict the market or economic conditions. There is no guarantee that the fund will preserve either income or capital and, as with other mutual fund investments, you could lose money even if the fund is at or close to its designated retirement year. Under normal circumstances, any deviation from the target allocation is not expected to be greater than plus or minus 10%.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is designed for investors who anticipate reevaluating their retirement allocation strategies at the target date. Under normal market conditions, the fund expects to allocate 8% of its assets to equity underlying funds in its designated retirement year and to maintain that static allocation thereafter. This static allocation may be appropriate for some investors, but others may wish to reallocate their investments at retirement.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in underlying funds that invest in a broad range of equity, fixed-income, and alternative/specialty securities and asset classes, including, but not limited to, U.S. and foreign securities, including emerging-market securities, commodities, asset-backed securities, small-cap securities, and below-investment-grade securities (i.e., junk bonds). The underlying funds may also use derivatives, such as swaps, foreign currency forwards, futures, and options, in each case for the purposes of reducing risk, obtaining efficient market exposure and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund will invest in various passively managed underlying funds that as a group hold a wide range of equity-type securities in their portfolios, including convertible securities. The fund may also invest in various actively managed funds. The fund is not designed to track an index or group of indexes. Equity-type securities include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. Certain equity underlying funds may invest in initial public offerings (IPOs). Each of the equity underlying funds has its own investment strategy that, for example, may focus on growth stocks or value stocks, or may employ a strategy combining growth and income stocks, and/or may invest in derivatives such as credit default swaps, foreign currency forwards, interest rate swaps, options on securities, and futures contracts. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from shorter to longer term. The fixed-income underlying funds collectively hold various types of debt instruments such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging market securities). Certain underlying funds may invest in illiquid securities, and certain underlying funds may be non-diversified.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest directly in exchange-traded funds (ETFs), exchange-traded notes (ETNs), the securities of other investment companies, U.S. government securities, and other types of investments such as derivatives, including credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, in each case for the purposes of reducing risk, obtaining efficient market exposure, and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;To the extent legally permitted, the Board of Trustees of the fund may, in its discretion, determine to combine the fund with another fund without shareholder approval if the target allocation of the fund matches the target allocation of the other fund, although there is no assurance that the Board of Trustees will so determine at any point.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund bears its own expenses and, in addition, indirectly bears its proportionate share of the expenses of the underlying funds in which it invests. The fund's performance reflects both the managers' allocation decisions and the performance of the underlying funds.&lt;/div&gt;

These actions, which could include legislative, regulatory, or economic initiatives, might have unforeseeable consequences and could adversely affect the fund's performance or otherwise constrain the fund's ability to achieve its investment objective.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in equity securities than John Hancock Multi-Index Preservation Portfolios with closer target dates, equity security risks are more prevalent in this fund than in these other target-date funds. In addition to equity securities risk, the fund's other main risk factors are listed below in alphabetical order. &lt;i&gt;Before investing, be sure to read the additional descriptions of these risks beginning on page 62 of the prospectus.&lt;/i&gt;            
            &lt;/div&gt;

                 &lt;i&gt; Principal risks of investing in the fund of funds    &lt;/i&gt;           
               &lt;/b&gt;&lt;/div&gt;             
                     
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk based on the nature of their support.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Investment company securities risk.&lt;/b&gt; A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lifecycle risk.&lt;/b&gt; Managers might not correctly predict market or economic conditions, and you could lose money even close to, during, or after the fund's designated retirement year.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Target allocation risk.&lt;/b&gt; The fund's risk profile will change due to reallocation or rebalancing of portfolio assets as the fund approaches its target date.&lt;/div&gt;         
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
               &lt;i&gt;   Principal risks of investing in the underlying funds   &lt;/i&gt;            
               &lt;/b&gt;&lt;/div&gt;             
                     
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Short sales risk.&lt;/b&gt; Short sales involve costs and risk. A fund must pay the lender interest on the security it borrows, and the fund will lose money if the price of the security increases between the time of the short sale and the date when the fund replaces the borrowed security.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

               &lt;b&gt;Russell 3000 Index/MSCI ACWI ex-USA Index/Bloomberg Barclays U.S. Aggregate Bond Index&lt;/b&gt; This custom blended benchmark (Custom Benchmark) is based on the fund's asset allocation glide path shown above and will reflect a more conservative asset allocation over time. The information shows how the fund's performance compares with the returns of an index of funds with similar investment objectives. From March 30, 2016 to November 30, 2017, the Custom Benchmark consisted of the following indices and approximate weightings: 57.40% Russell 3000 Index, 24.60% MSCI ACWI ex-USA Index, and 18.00% Bloomberg Barclays U.S. Aggregate Bond Index. The weightings of the indices in the Custom Benchmark are adjusted annually to reflect changes in the fund's target asset allocation in accordance with the annual roll-down of the glide path described above.&lt;/div&gt;

Because Class R5 shares of the fund had not commenced operations as of the date of this prospectus, the returns shown are those of Class 1 shares. Returns for Class R5 shares would have been substantially similar to returns of Class 1 shares because each share class is invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.&lt;/div&gt;

Your actual after-tax returns may be different. After-tax returns are not relevant to shares held in an IRA, 401(k), or other tax-advantaged investment plan.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 7% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund primarily invests its assets in underlying funds using an asset allocation strategy designed for investors in or near retirement. Under normal market conditions, the fund is expected to maintain an allocation of about 8% of its assets in underlying funds that invest primarily in equity securities.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund typically will have greater exposure to underlying funds that invest primarily in fixed-income securities than will other John Hancock Multi-Index Preservation Portfolios, which are designed for investors who plan to retire around a specific target date.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund's allocations to equity and fixed-income are referred to as neutral because they do not reflect active decisions made by the portfolio managers to produce an overweight or an underweight position in a particular asset class. The fund has a target allocation to underlying funds that invest in the broad asset classes of equity and fixed-income securities but may also allocate its assets to underlying funds that invest outside these asset classes to protect the fund or help it achieve its objective. For example, the fund may also allocate its assets to underlying funds that invest in alternative and specialty asset classes. The investment advisor may change the target allocation without shareholder approval if it believes such change would benefit the fund and its shareholders. There is no guarantee that the managers will correctly predict the market or economic conditions. There is no guarantee that the fund will preserve either income or capital and, as with other mutual fund investments, you could lose money. Unlike other John Hancock Multi-Index Preservation Portfolios, the fund is not designed to decrease its equity holdings over time. The fund is designed for an investor in or near retirement, and it is anticipated that investors will make gradual withdrawals from the fund.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in underlying funds that invest in a broad range of equity, fixed-income, and alternative/specialty securities and asset classes, including, but not limited to, U.S. and foreign securities, including emerging-market securities, commodities, asset-backed securities, small-cap securities, and below-investment-grade securities (i.e., junk bonds). The underlying funds may also use derivatives, such as swaps, foreign currency forwards, futures, and options, in each case for the purposes of reducing risk, obtaining efficient market exposure and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund will invest in various passively managed underlying funds that as a group hold a wide range of equity-type securities in their portfolios, including convertible securities. The fund may also invest in various actively managed funds. The fund is not designed to track an index or group of indexes. Equity-type securities include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. Certain equity underlying funds may invest in initial public offerings (IPOs). Each of the equity underlying funds has its own investment strategy that, for example, may focus on growth stocks or value stocks, or may employ a strategy combining growth and income stocks, and/or may invest in derivatives such as credit default swaps, foreign currency forwards, interest rate swaps, options on securities, and futures contracts. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from shorter to longer term. The fixed-income underlying funds collectively hold various types of debt instruments such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging market securities). Certain underlying funds may invest in illiquid securities, and certain underlying funds may be non-diversified.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest directly in exchange-traded funds (ETFs), exchange-traded notes (ETNs), the securities of other investment companies, U.S. government securities, and other types of investments such as derivatives, including credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, in each case for the purposes of reducing risk, obtaining efficient market exposure, and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;To the extent legally permitted, the Board of Trustees of the fund may, in its discretion, determine to combine the fund with another fund without shareholder approval if the target allocation of the fund matches the target allocation of the other fund, although there is no assurance that the Board of Trustees will so determine at any point.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund bears its own expenses and, in addition, indirectly bears its proportionate share of the expenses of the underlying funds in which it invests. The fund's performance reflects both the managers' allocation decisions and the performance of the underlying funds.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Many factors affect performance, and fund shares will fluctuate in price, meaning you could lose money. The fund's investment strategy may not produce the intended results.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;During periods of heightened market volatility or reduced liquidity, governments, their agencies, or other regulatory bodies, both within the United States and abroad, may take steps to intervene. These actions, which could include legislative, regulatory, or economic initiatives, might have unforeseeable consequences and could adversely affect the fund's performance or otherwise constrain the fund's ability to achieve its investment objective.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in fixed-income securities than John Hancock Multi-Index Preservation Portfolios with target dates that are more distant, fixed-income securities risks are more prevalent in this fund than in these other target date funds. In addition to fixed-income securities risk, the fund's other main risk factors are listed below in alphabetical order. &lt;i&gt;Before investing, be sure to read the additional descriptions of these risks beginning on page 62 of the prospectus.&lt;/i&gt;            
            &lt;/div&gt;

               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk based on the nature of their support.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;

               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;

               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;

               &lt;b&gt;Lifecycle risk.&lt;/b&gt; Managers might not correctly predict market or economic conditions, and you could lose money even though the fund's designated retirement year has already passed.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Target allocation risk.&lt;/b&gt; The fund's risk profile will change due to reallocation or rebalancing of portfolio assets as the fund approaches its target date.&lt;/div&gt;

              &lt;i&gt;    Principal risks of investing in the underlying funds   &lt;/i&gt;            
               &lt;/b&gt;&lt;/div&gt;             
                     
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality.

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;

               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;

               &lt;b&gt;Short sales risk.&lt;/b&gt; Short sales involve costs and risk. A fund must pay the lender interest on the security it borrows, and the fund will lose money if the price of the security increases between the time of the short sale and the date when the fund replaces the borrowed security.&lt;/div&gt;

               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The following information illustrates the variability of the fund's returns and provides some indication of the risks of investing in the fund by showing changes in the fund's performance from year to year and by showing how the fund's average annual returns compared with a broad-based market index. Past performance (before and after taxes) does not indicate future results. All figures assume dividend reinvestment. Performance information is updated daily, monthly, and quarterly and may be obtained at our website, jhinvestments.com, or by calling 888-972-8696 between 8:30 A.M. and 5:00 P.M., Eastern time, on most business days.&lt;/div&gt;

               &lt;b&gt;Russell 3000 Index/MSCI ACWI ex-USA Index/Bloomberg Barclays U.S. Aggregate Bond Index&lt;/b&gt; This custom blended benchmark (Custom Benchmark) is designed to reflect the fund's asset allocation under normal market conditions. The information shows how the fund's performance compares with the returns of an index of funds with similar investment objectives. From December 1, 2014, the Custom Benchmark has consisted of the following indices and approximate weightings: 5.60% Russell 3000 Index, 2.40% MSCI ACWI ex-USA Index, and 92.00% Bloomberg Barclays U.S. Aggregate Bond Index. Prior to reaching its current allocation, the weightings of the indices in the Custom Benchmark were adjusted annually to reflect changes in the fund's target asset allocation.&lt;/div&gt;

Because Class R5 shares of the fund had not commenced operations as of the date of this prospectus, the returns shown are those of Class 1 shares. Returns for Class R5 shares would have been substantially similar to returns of Class 1 shares because each share class is invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.&lt;/div&gt;

Your actual after-tax returns may be different. After-tax returns are not relevant to shares held in an IRA, 401(k), or other tax-advantaged investment plan.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;This example is intended to help you compare the cost of investing in the fund with the cost of investing in other mutual funds. Please see below a hypothetical example showing the expenses of a $10,000 investment for the time periods indicated and then assuming you sell all of your shares at the end of those periods. The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 20% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests substantially all of its assets in underlying funds using an asset allocation strategy designed for investors expected to retire around the year 2010.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The portfolio managers of the fund allocate assets among the underlying funds according to an asset allocation strategy that becomes increasingly conservative over time. John Hancock Multimanager 2010 Lifetime Portfolio has a target asset allocation of 38.75% of its assets in underlying funds that invest primarily in equity securities. The fund will have a greater exposure to underlying funds that invest primarily in fixed-income securities than will a John Hancock Multimanager Lifetime Portfolio with a more distant target date. To reduce investment risk and volatility as retirement approaches and in the postretirement years, the asset allocation strategy will change over time according to a predetermined "glide path" shown in the following chart. The fund may be a primary source of income for its shareholders after retirement.&lt;/div&gt;         
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                  GLIDE PATH CHART               
               &lt;/b&gt;&lt;/div&gt;    
 &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;/div&gt;         
                     &lt;img alt="glidepath chart" src="glidepath.jpg"&gt;&lt;/img&gt;    
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The allocations reflected in the glide path are referred to as target allocations because they do not reflect active decisions made by the portfolio managers to produce an overweight or an underweight position in a particular asset class. The fund has a target allocation to underlying funds that invest in the broad asset classes of equity and fixed-income securities, but may also allocate its assets to underlying funds that invest outside these asset classes to protect the fund or help it achieve its objective. For example, the fund also typically allocates a portion of its assets to underlying funds that invest in alternative and specialty asset classes. The fund's allocation to alternative and specialty underlying funds may vary over time and in relation to a John Hancock Multimanager Lifetime Portfolio with a different target date. The managers may change the target allocation without shareholder approval if they believe that such change would benefit the fund and its shareholders. Under normal circumstances, any deviation from the target allocation is not expected to be greater than plus or minus 10%.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Within the prescribed percentage allocation, the managers select the percentage level to be maintained in specific underlying funds. New investments made by the fund may be directed to particular underlying funds in an effort to maintain the desired target allocations. There is no guarantee that the portfolio managers will correctly predict the market or economic conditions and, as with other mutual fund investments, you could lose money even if the fund is at or close to its designated retirement year or in its postretirement stage.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is designed for investors who may remain invested in the fund through their retirement years. The fund will continue to be managed according to an allocation strategy that becomes increasingly conservative over time until approximately twenty years after retirement, at which time the fund expects to maintain a static allocation of approximately 25% of its assets in equity underlying funds.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in underlying funds that invest in a broad range of equity, fixed-income and alternative/specialty securities and asset classes, including, but not limited to, U.S. and foreign securities, including emerging-market securities, commodities, asset-backed securities, small-cap securities, and below-investment-grade securities (i.e., junk bonds). The underlying funds may also use derivatives, such as swaps, foreign currency forwards, futures, and options, in each case for the purposes of reducing risk, obtaining efficient market exposure and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in various actively managed underlying funds that as a group hold a wide range of equity-type securities in their portfolios, including convertible securities. These include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. The fund may also invest in various passively managed underlying funds. Certain equity underlying funds may invest in initial public offerings (IPOs). Each of the equity underlying funds has its own investment strategy that, for example, may focus on growth stocks or value stocks, or may employ a strategy combining growth and income stocks, and/or may invest in derivatives such as credit default swaps, foreign currency forwards, interest rate swaps, options on securities, and futures contracts. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from shorter to longer term. The fixed-income underlying funds collectively hold various types of debt instruments such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging market securities). Certain underlying funds may invest in illiquid securities, and certain underlying funds may be non-diversified.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest directly in exchange-traded funds (ETFs), exchange-traded notes (ETNs), the securities of other investment companies, U.S. government securities, and other types of investments such as derivatives, including credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, in each case for the purposes of reducing risk, obtaining efficient market exposure, and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;To the extent permitted by law, the Board of Trustees of the fund may, in its discretion, determine to combine the fund with another fund without shareholder approval if the target allocation of the fund matches the target allocation of the other fund, although there is no assurance that the Board of Trustees will so determine at any point. The fund bears its own expenses and, in addition, indirectly bears its proportionate share of the expenses of the underlying funds in which it invests. The fund's performance reflects both the managers' allocation decisions and the performance of the underlying funds.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Many factors affect performance, and fund shares will fluctuate in price, meaning you could lose money. The fund's investment strategy may not produce the intended results.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;During periods of heightened market volatility or reduced liquidity, governments, their agencies, or other regulatory bodies, both within the United States and abroad, may take steps to intervene. These actions, which could include legislative, regulatory, or economic initiatives, might have unforeseeable consequences and could adversely affect the fund's performance or otherwise constrain the fund's ability to achieve its investment objective.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in fixed-income securities than John Hancock Multimanager Lifetime Portfolios with more distant target dates, fixed-income risks are more prevalent in this fund than in these other target date funds. In addition to fixed-income securities risk, the fund's other main risk factors are listed below in alphabetical order. &lt;i&gt;Before investing, be sure to read the additional descriptions of these risks beginning on page 78 of the prospectus.&lt;/i&gt;            
            &lt;/div&gt;

               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk based on the nature of their support.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;

               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;

               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;

               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;

               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The following information illustrates the variability of the fund's returns and provides some indication of the risks of investing in the fund by showing changes in the fund's performance from year to year and by showing how the fund's average annual returns compared with a broad-based market index. Past performance (before and after taxes) does not indicate future results. All figures assume dividend reinvestment. Performance information is updated daily, monthly, and quarterly and may be obtained at our website, jhinvestments.com, or by calling 800-225-5291 (Class A), Monday to Thursday, 8:00 A.M.&#8212;7:00 P.M., and Friday, 8:00 A.M.&#8212;6:00 P.M., Eastern time, or 888-972-8696 (Class I, Class R1, Class R2, Class R3, Class R4, Class R5, and Class R6) between 8:30 A.M. and 5:00 P.M., Eastern time, on most business days.&lt;/div&gt;

The information shows how the fund's performance compares with the returns of an index of funds with similar investment objectives. From December 1, 2016 to November 30, 2017, the Custom Benchmark consisted of the following indices and approximate weightings: 28.88% Russell 3000 Index, 12.37% MSCI ACWI ex-USA Index, 47.00% Bloomberg Barclays U.S. Aggregate Bond Index, and 11.75% ICE Bank of America Merrill Lynch U.S. High Yield Master II Index. The weightings of the indices in the Custom Benchmark are adjusted annually to reflect changes in the fund's target asset allocation in accordance with the annual roll-down of the glide path described above and differed in periods prior to December 1, 2016.&lt;/div&gt;

Returns prior to a class's commencement date are those of Class R1 shares. Returns for Class I, Class R2, and Class R6 shares would have been substantially similar to returns of Class R1 shares because each share class is invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.&lt;/div&gt;

Your actual after-tax returns may be different. After-tax returns are not relevant to shares held in an IRA, 401(k), or other tax-advantaged investment plan.

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 17% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests substantially all of its assets in underlying funds using an asset allocation strategy designed for investors expected to retire around the year 2015.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The portfolio managers of the fund allocate assets among the underlying funds according to an asset allocation strategy that becomes increasingly conservative over time. John Hancock Multimanager 2015 Lifetime Portfolio has a target asset allocation of 45% of its assets in underlying funds that invest primarily in equity securities. The fund will have a greater exposure to underlying funds that invest primarily in fixed-income securities than will a John Hancock Multimanager Lifetime Portfolio with a more distant target date. To reduce investment risk and volatility as retirement approaches and in the postretirement years, the asset allocation strategy will change over time according to a predetermined "glide path" shown in the following chart. The fund may be a primary source of income for its shareholders after retirement.&lt;/div&gt;         
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                  GLIDE PATH CHART               
               &lt;/b&gt;&lt;/div&gt;       
 &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;/div&gt;      
                 &lt;img alt="glidepath chart" src="glidepath.jpg"&gt;&lt;/img&gt;      
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The allocations reflected in the glide path are referred to as target allocations because they do not reflect active decisions made by the portfolio managers to produce an overweight or an underweight position in a particular asset class. The fund has a target allocation to underlying funds that invest in the broad asset classes of equity and fixed-income securities, but may also allocate its assets to underlying funds that invest outside these asset classes to protect the fund or help it achieve its objective. For example, the fund also typically allocates a portion of its assets to underlying funds that invest in alternative and specialty asset classes. The fund's allocation to alternative and specialty underlying funds may vary over time and in relation to a John Hancock Multimanager Lifetime Portfolio with a different target date. The managers may change the target allocation without shareholder approval if they believe that such change would benefit the fund and its shareholders. Under normal circumstances, any deviation from the target allocation is not expected to be greater than plus or minus 10%.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Within the prescribed percentage allocation, the managers select the percentage level to be maintained in specific underlying funds. New investments made by the fund may be directed to particular underlying funds in an effort to maintain the desired target allocations. There is no guarantee that the portfolio managers will correctly predict the market or economic conditions and, as with other mutual fund investments, you could lose money even if the fund is at or close to its designated retirement year or in its postretirement stage.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is designed for investors who may remain invested in the fund through their retirement years. The fund will continue to be managed according to an allocation strategy that becomes increasingly conservative over time until approximately twenty years after retirement, at which time the fund expects to maintain a static allocation of approximately 25% of its assets in equity underlying funds.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in underlying funds that invest in a broad range of equity, fixed-income and alternative/specialty securities and asset classes, including, but not limited to, U.S. and foreign securities, including emerging-market securities, commodities, asset-backed securities, small-cap securities, and below-investment-grade securities (i.e., junk bonds). The underlying funds may also use derivatives, such as swaps, foreign currency forwards, futures, and options, in each case for the purposes of reducing risk, obtaining efficient market exposure and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in various actively managed underlying funds that as a group hold a wide range of equity-type securities in their portfolios, including convertible securities. These include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. The fund may also invest in various passively managed underlying funds. Certain equity underlying funds may invest in initial public offerings (IPOs). Each of the equity underlying funds has its own investment strategy that, for example, may focus on growth stocks or value stocks, or may employ a strategy combining growth and income stocks, and/or may invest in derivatives such as credit default swaps, foreign currency forwards, interest rate swaps, options on securities, and futures contracts. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from shorter to longer term. The fixed-income underlying funds collectively hold various types of debt instruments such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging market securities). Certain underlying funds may invest in illiquid securities, and certain underlying funds may be non-diversified.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest directly in exchange-traded funds (ETFs), exchange-traded notes (ETNs), the securities of other investment companies, U.S. government securities, and other types of investments such as derivatives, including credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, in each case for the purposes of reducing risk, obtaining efficient market exposure, and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;To the extent permitted by law, the Board of Trustees of the fund may, in its discretion, determine to combine the fund with another fund without shareholder approval if the target allocation of the fund matches the target allocation of the other fund, although there is no assurance that the Board of Trustees will so determine at any point. The fund bears its own expenses and, in addition, indirectly bears its proportionate share of the expenses of the underlying funds in which it invests. The fund's performance reflects both the managers' allocation decisions and the performance of the underlying funds.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;During periods of heightened market volatility or reduced liquidity, governments, their agencies, or other regulatory bodies, both within the United States and abroad, may take steps to intervene. These actions, which could include legislative, regulatory, or economic initiatives, might have unforeseeable consequences and could adversely affect the fund's performance or otherwise constrain the fund's ability to achieve its investment objective.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in fixed-income securities than John Hancock Multimanager Lifetime Portfolios with more distant target dates, fixed-income risks are more prevalent in this fund than in these other target date funds.

               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk based on the nature of their support.&lt;/div&gt;

               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;

               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;

               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;

               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;

               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Investment company securities risk.&lt;/b&gt; A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lifecycle risk.&lt;/b&gt; Managers might not correctly predict market or economic conditions, and you could lose money even close to, during, or after the fund's designated retirement year.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Target allocation risk.&lt;/b&gt; The fund's risk profile will change due to reallocation or rebalancing of portfolio assets as the fund approaches its target date.&lt;/div&gt;

               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality.

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

Returns for Class I, Class R2, and Class R6 shares would have been substantially similar to returns of Class R1 shares because each share class is invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Please note that after-tax returns (shown for Class A shares only) reflect the highest individual federal marginal income-tax rate in effect as of the date provided and do not reflect any state or local taxes. Your actual after-tax returns may be different. After-tax returns are not relevant to shares held in an IRA, 401(k), or other tax-advantaged investment plan. After-tax returns for other share classes would vary.&lt;/div&gt;

Intermediaries may have different policies and procedures regarding the availability of front-end sales charge waivers or CDSC waivers (See Appendix 1 - Intermediary sales charge waivers, which includes information about specific sales charge waivers applicable to the intermediaries identified therein). More information about these and other discounts is available from your financial representative and on pages 115 to 117 of this prospectus under "Sales charge reductions and waivers" or pages 273 to 277 of the fund's Statement of Additional Information under "Sales Charges on Class A, Class B, and Class C Shares."&lt;/div&gt;

The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 19% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests substantially all of its assets in underlying funds using an asset allocation strategy designed for investors expected to retire around the year 2020.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The portfolio managers of the fund allocate assets among the underlying funds according to an asset allocation strategy that becomes increasingly conservative over time. John Hancock Multimanager 2020 Lifetime Portfolio has a target asset allocation of 54% of its assets in underlying funds that invest primarily in equity securities. The fund will have a greater exposure to underlying funds that invest primarily in equity securities than will a John Hancock Multimanager Lifetime Portfolio with a closer target date. To reduce investment risk and volatility as retirement approaches and in the postretirement years, the asset allocation strategy will change over time according to a predetermined "glide path" shown in the following chart. The fund may be a primary source of income for its shareholders after retirement.&lt;/div&gt;         
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                  GLIDE PATH CHART               
               &lt;/b&gt;&lt;/div&gt;     
 &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;/div&gt;        
                  &lt;img alt="glidepath chart" src="glidepath.jpg"&gt;&lt;/img&gt;     
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The allocations reflected in the glide path are referred to as target allocations because they do not reflect active decisions made by the portfolio managers to produce an overweight or an underweight position in a particular asset class. The fund has a target allocation to underlying funds that invest in the broad asset classes of equity and fixed-income securities, but may also allocate its assets to underlying funds that invest outside these asset classes to protect the fund or help it achieve its objective. For example, the fund also typically allocates a portion of its assets to underlying funds that invest in alternative and specialty asset classes. The fund's allocation to alternative and specialty underlying funds may vary over time and in relation to a John Hancock Multimanager Lifetime Portfolio with a different target date. The managers may change the target allocation without shareholder approval if they believe that such change would benefit the fund and its shareholders. Under normal circumstances, any deviation from the target allocation is not expected to be greater than plus or minus 10%.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Within the prescribed percentage allocation, the managers select the percentage level to be maintained in specific underlying funds. New investments made by the fund may be directed to particular underlying funds in an effort to maintain the desired target allocations. There is no guarantee that the portfolio managers will correctly predict the market or economic conditions and, as with other mutual fund investments, you could lose money even if the fund is at or close to its designated retirement year or in its postretirement stage.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is designed for investors who may remain invested in the fund through their retirement years. The fund will continue to be managed according to an allocation strategy that becomes increasingly conservative over time until approximately twenty years after retirement, at which time the fund expects to maintain a static allocation of approximately 25% of its assets in equity underlying funds.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in underlying funds that invest in a broad range of equity, fixed-income and alternative/specialty securities and asset classes, including, but not limited to, U.S. and foreign securities, including emerging-market securities, commodities, asset-backed securities, small-cap securities, and below-investment-grade securities (i.e., junk bonds). The underlying funds may also use derivatives, such as swaps, foreign currency forwards, futures, and options, in each case for the purposes of reducing risk, obtaining efficient market exposure and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in various actively managed underlying funds that as a group hold a wide range of equity-type securities in their portfolios, including convertible securities. These include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. The fund may also invest in various passively managed underlying funds. Certain equity underlying funds may invest in initial public offerings (IPOs). Each of the equity underlying funds has its own investment strategy that, for example, may focus on growth stocks or value stocks, or may employ a strategy combining growth and income stocks, and/or may invest in derivatives such as credit default swaps, foreign currency forwards, interest rate swaps, options on securities, and futures contracts. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from shorter to longer term. The fixed-income underlying funds collectively hold various types of debt instruments such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging market securities). Certain underlying funds may invest in illiquid securities, and certain underlying funds may be non-diversified.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest directly in exchange-traded funds (ETFs), exchange-traded notes (ETNs), the securities of other investment companies, U.S. government securities, and other types of investments such as derivatives, including credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, in each case for the purposes of reducing risk, obtaining efficient market exposure, and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;To the extent permitted by law, the Board of Trustees of the fund may, in its discretion, determine to combine the fund with another fund without shareholder approval if the target allocation of the fund matches the target allocation of the other fund, although there is no assurance that the Board of Trustees will so determine at any point. The fund bears its own expenses and, in addition, indirectly bears its proportionate share of the expenses of the underlying funds in which it invests. The fund's performance reflects both the managers' allocation decisions and the performance of the underlying funds.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Many factors affect performance, and fund shares will fluctuate in price, meaning you could lose money. The fund's investment strategy may not produce the intended results.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;During periods of heightened market volatility or reduced liquidity, governments, their agencies, or other regulatory bodies, both within the United States and abroad, may take steps to intervene. These actions, which could include legislative, regulatory, or economic initiatives, might have unforeseeable consequences and could adversely affect the fund's performance or otherwise constrain the fund's ability to achieve its investment objective.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in equity securities than John Hancock Multimanager Lifetime Portfolios with closer target dates, equity security risks are more prevalent in this fund than in these other target-date funds. In addition to equity securities risk, the fund's other main risk factors are listed below in alphabetical order. &lt;i&gt;Before investing, be sure to read the additional descriptions of these risks beginning on page 78 of the prospectus.&lt;/i&gt;            
            &lt;/div&gt;

               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk based on the nature of their support.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;

               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;

               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;

               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;

               &lt;b&gt;Target allocation risk.&lt;/b&gt; The fund's risk profile will change due to reallocation or rebalancing of portfolio assets as the fund approaches its target date.&lt;/div&gt;

               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;

               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;

Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide.

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;

               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;

               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;

               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;

               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The following information illustrates the variability of the fund's returns and provides some indication of the risks of investing in the fund by showing changes in the fund's performance from year to year and by showing how the fund's average annual returns compared with a broad-based market index. Past performance (before and after taxes) does not indicate future results. All figures assume dividend reinvestment. Performance information is updated daily, monthly, and quarterly and may be obtained at our website, jhinvestments.com, or by calling 800-225-5291 (Class A), Monday to Thursday, 8:00 A.M.&#8212;7:00 P.M., and Friday, 8:00 A.M.&#8212;6:00 P.M., Eastern time, or 888-972-8696 (Class I, Class R1, Class R2, Class R3, Class R4, Class R5, and Class R6) between 8:30 A.M. and 5:00 P.M., Eastern time, on most business days.&lt;/div&gt;

The information shows how the fund's performance compares with the returns of an index of funds with similar investment objectives. From December 1, 2016 to November 30, 2017, the Custom Benchmark consisted of the following indices and approximate weightings: 40.60% Russell 3000 Index, 17.40% MSCI ACWI ex-USA Index, 33.60% Bloomberg Barclays U.S. Aggregate Bond Index, and 8.40% ICE Bank of America Merrill Lynch U.S. High Yield Master II Index. The weightings of the indices in the Custom Benchmark are adjusted annually to reflect changes in the fund's target asset allocation in accordance with the annual roll-down of the glide path described above and differed in periods prior to December 1, 2016.&lt;/div&gt;

Returns prior to a class's commencement date are those of Class R1 shares. Returns for Class I, Class R2, and Class R6 shares would have been substantially similar to returns of Class R1 shares because each share class is invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.&lt;/div&gt;

Your actual after-tax returns may be different. After-tax returns are not relevant to shares held in an IRA, 401(k), or other tax-advantaged investment plan. After-tax returns for other share classes would vary.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 21% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests substantially all of its assets in underlying funds using an asset allocation strategy designed for investors expected to retire around the year 2025.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The portfolio managers of the fund allocate assets among the underlying funds according to an asset allocation strategy that becomes increasingly conservative over time. John Hancock Multimanager 2025 Lifetime Portfolio has a target asset allocation of 65% of its assets in underlying funds that invest primarily in equity securities. The fund will have a greater exposure to underlying funds that invest primarily in equity securities than will a John Hancock Multimanager Lifetime Portfolio with a closer target date. To reduce investment risk and volatility as retirement approaches and in the postretirement years, the asset allocation strategy will change over time according to a predetermined "glide path" shown in the following chart. The fund may be a primary source of income for its shareholders after retirement.&lt;/div&gt;         
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                  GLIDE PATH CHART               
               &lt;/b&gt;&lt;/div&gt;    
 &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;/div&gt;         
                 &lt;img alt="glidepath chart" src="glidepath.jpg"&gt;&lt;/img&gt;      
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The allocations reflected in the glide path are referred to as target allocations because they do not reflect active decisions made by the portfolio managers to produce an overweight or an underweight position in a particular asset class. The fund has a target allocation to underlying funds that invest in the broad asset classes of equity and fixed-income securities, but may also allocate its assets to underlying funds that invest outside these asset classes to protect the fund or help it achieve its objective. For example, the fund also typically allocates a portion of its assets to underlying funds that invest in alternative and specialty asset classes. The fund's allocation to alternative and specialty underlying funds may vary over time and in relation to a John Hancock Multimanager Lifetime Portfolio with a different target date. The managers may change the target allocation without shareholder approval if they believe that such change would benefit the fund and its shareholders. Under normal circumstances, any deviation from the target allocation is not expected to be greater than plus or minus 10%.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Within the prescribed percentage allocation, the managers select the percentage level to be maintained in specific underlying funds. New investments made by the fund may be directed to particular underlying funds in an effort to maintain the desired target allocations. There is no guarantee that the portfolio managers will correctly predict the market or economic conditions and, as with other mutual fund investments, you could lose money even if the fund is at or close to its designated retirement year or in its postretirement stage.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is designed for investors who may remain invested in the fund through their retirement years. The fund will continue to be managed according to an allocation strategy that becomes increasingly conservative over time until approximately twenty years after retirement, at which time the fund expects to maintain a static allocation of approximately 25% of its assets in equity underlying funds.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in underlying funds that invest in a broad range of equity, fixed-income and alternative/specialty securities and asset classes, including, but not limited to, U.S. and foreign securities, including emerging-market securities, commodities, asset-backed securities, small-cap securities, and below-investment-grade securities (i.e., junk bonds). The underlying funds may also use derivatives, such as swaps, foreign currency forwards, futures, and options, in each case for the purposes of reducing risk, obtaining efficient market exposure and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in various actively managed underlying funds that as a group hold a wide range of equity-type securities in their portfolios, including convertible securities. These include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. The fund may also invest in various passively managed underlying funds. Certain equity underlying funds may invest in initial public offerings (IPOs). Each of the equity underlying funds has its own investment strategy that, for example, may focus on growth stocks or value stocks, or may employ a strategy combining growth and income stocks, and/or may invest in derivatives such as credit default swaps, foreign currency forwards, interest rate swaps, options on securities, and futures contracts. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from shorter to longer term. The fixed-income underlying funds collectively hold various types of debt instruments such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging market securities). Certain underlying funds may invest in illiquid securities, and certain underlying funds may be non-diversified.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest directly in exchange-traded funds (ETFs), exchange-traded notes (ETNs), the securities of other investment companies, U.S. government securities, and other types of investments such as derivatives, including credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, in each case for the purposes of reducing risk, obtaining efficient market exposure, and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;To the extent permitted by law, the Board of Trustees of the fund may, in its discretion, determine to combine the fund with another fund without shareholder approval if the target allocation of the fund matches the target allocation of the other fund, although there is no assurance that the Board of Trustees will so determine at any point. The fund bears its own expenses and, in addition, indirectly bears its proportionate share of the expenses of the underlying funds in which it invests. The fund's performance reflects both the managers' allocation decisions and the performance of the underlying funds.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Many factors affect performance, and fund shares will fluctuate in price, meaning you could lose money. The fund's investment strategy may not produce the intended results.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;During periods of heightened market volatility or reduced liquidity, governments, their agencies, or other regulatory bodies, both within the United States and abroad, may take steps to intervene. These actions, which could include legislative, regulatory, or economic initiatives, might have unforeseeable consequences and could adversely affect the fund's performance or otherwise constrain the fund's ability to achieve its investment objective.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in equity securities than John Hancock Multimanager Lifetime Portfolios with closer target dates, equity security risks are more prevalent in this fund than in these other target-date funds. In addition to equity securities risk, the fund's other main risk factors are listed below in alphabetical order. &lt;i&gt;Before investing, be sure to read the additional descriptions of these risks beginning on page 78 of the prospectus.&lt;/i&gt;

               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;

               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;

               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;

               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;

               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;

               &lt;b&gt;Lifecycle risk.&lt;/b&gt; Managers might not correctly predict market or economic conditions, and you could lose money even close to, during, or after the fund's designated retirement year.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Target allocation risk.&lt;/b&gt; The fund's risk profile will change due to reallocation or rebalancing of portfolio assets as the fund approaches its target date.&lt;/div&gt;

               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;

               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;

               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide.

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;

               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

Past performance (before and after taxes) does not indicate future results. All figures assume dividend reinvestment. Performance information is updated daily, monthly, and quarterly and may be obtained at our website, jhinvestments.com, or by calling 800-225-5291 (Class A), Monday to Thursday, 8:00 A.M.&#8212;7:00 P.M., and Friday, 8:00 A.M.&#8212;6:00 P.M., Eastern time, or 888-972-8696 (Class I, Class R1, Class R2, Class R3, Class R4, Class R5, and Class R6) between 8:30 A.M. and 5:00 P.M., Eastern time, on most business days.&lt;/div&gt;

The information shows how the fund's performance compares with the returns of an index of funds with similar investment objectives. From December 1, 2016 to November 30, 2017, the Custom Benchmark consisted of the following indices and approximate weightings: 49.00% Russell 3000 Index, 21.00% MSCI ACWI ex-USA Index, 24.00% Bloomberg Barclays U.S. Aggregate Bond Index, and 6.00% ICE Bank of America Merrill Lynch U.S. High Yield Master II Index. The weightings of the indices in the Custom Benchmark are adjusted annually to reflect changes in the fund's target asset allocation in accordance with the annual roll-down of the glide path described above and differed in periods prior to December 1, 2016.&lt;/div&gt;

Returns prior to a class's commencement date are those of Class R1 shares. Returns for Class I, Class R2, and Class R6 shares would have been substantially similar to returns of Class R1 shares because each share class is invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.&lt;/div&gt;

Please see below a hypothetical example showing the expenses of a $10,000 investment for the time periods indicated and then assuming you sell all of your shares at the end of those periods. The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 20% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests substantially all of its assets in underlying funds using an asset allocation strategy designed for investors expected to retire around the year 2030.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The portfolio managers of the fund allocate assets among the underlying funds according to an asset allocation strategy that becomes increasingly conservative over time. John Hancock Multimanager 2030 Lifetime Portfolio has a target asset allocation of 77% of its assets in underlying funds that invest primarily in equity securities. The fund will have a greater exposure to underlying funds that invest primarily in equity securities than will a John Hancock Multimanager Lifetime Portfolio with a closer target date. To reduce investment risk and volatility as retirement approaches and in the postretirement years, the asset allocation strategy will change over time according to a predetermined "glide path" shown in the following chart. The fund may be a primary source of income for its shareholders after retirement.&lt;/div&gt;         
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                  GLIDE PATH CHART               
               &lt;/b&gt;&lt;/div&gt;    
 &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;/div&gt;         
                  &lt;img alt="glidepath chart" src="glidepath.jpg"&gt;&lt;/img&gt;     
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The allocations reflected in the glide path are referred to as target allocations because they do not reflect active decisions made by the portfolio managers to produce an overweight or an underweight position in a particular asset class. The fund has a target allocation to underlying funds that invest in the broad asset classes of equity and fixed-income securities, but may also allocate its assets to underlying funds that invest outside these asset classes to protect the fund or help it achieve its objective. For example, the fund also typically allocates a portion of its assets to underlying funds that invest in alternative and specialty asset classes. The fund's allocation to alternative and specialty underlying funds may vary over time and in relation to a John Hancock Multimanager Lifetime Portfolio with a different target date. The managers may change the target allocation without shareholder approval if they believe that such change would benefit the fund and its shareholders. Under normal circumstances, any deviation from the target allocation is not expected to be greater than plus or minus 10%.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Within the prescribed percentage allocation, the managers select the percentage level to be maintained in specific underlying funds. New investments made by the fund may be directed to particular underlying funds in an effort to maintain the desired target allocations. There is no guarantee that the portfolio managers will correctly predict the market or economic conditions and, as with other mutual fund investments, you could lose money even if the fund is at or close to its designated retirement year or in its postretirement stage.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is designed for investors who may remain invested in the fund through their retirement years. The fund will continue to be managed according to an allocation strategy that becomes increasingly conservative over time until approximately twenty years after retirement, at which time the fund expects to maintain a static allocation of approximately 25% of its assets in equity underlying funds.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in underlying funds that invest in a broad range of equity, fixed-income and alternative/specialty securities and asset classes, including, but not limited to, U.S. and foreign securities, including emerging-market securities, commodities, asset-backed securities, small-cap securities, and below-investment-grade securities (i.e., junk bonds). The underlying funds may also use derivatives, such as swaps, foreign currency forwards, futures, and options, in each case for the purposes of reducing risk, obtaining efficient market exposure and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in various actively managed underlying funds that as a group hold a wide range of equity-type securities in their portfolios, including convertible securities. These include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. The fund may also invest in various passively managed underlying funds. Certain equity underlying funds may invest in initial public offerings (IPOs). Each of the equity underlying funds has its own investment strategy that, for example, may focus on growth stocks or value stocks, or may employ a strategy combining growth and income stocks, and/or may invest in derivatives such as credit default swaps, foreign currency forwards, interest rate swaps, options on securities, and futures contracts. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from shorter to longer term. The fixed-income underlying funds collectively hold various types of debt instruments such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging market securities). Certain underlying funds may invest in illiquid securities, and certain underlying funds may be non-diversified.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest directly in exchange-traded funds (ETFs), exchange-traded notes (ETNs), the securities of other investment companies, U.S. government securities, and other types of investments such as derivatives, including credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, in each case for the purposes of reducing risk, obtaining efficient market exposure, and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;To the extent permitted by law, the Board of Trustees of the fund may, in its discretion, determine to combine the fund with another fund without shareholder approval if the target allocation of the fund matches the target allocation of the other fund, although there is no assurance that the Board of Trustees will so determine at any point. The fund bears its own expenses and, in addition, indirectly bears its proportionate share of the expenses of the underlying funds in which it invests. The fund's performance reflects both the managers' allocation decisions and the performance of the underlying funds.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Many factors affect performance, and fund shares will fluctuate in price, meaning you could lose money. The fund's investment strategy may not produce the intended results.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;During periods of heightened market volatility or reduced liquidity, governments, their agencies, or other regulatory bodies, both within the United States and abroad, may take steps to intervene. These actions, which could include legislative, regulatory, or economic initiatives, might have unforeseeable consequences and could adversely affect the fund's performance or otherwise constrain the fund's ability to achieve its investment objective.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in equity securities than John Hancock Multimanager Lifetime Portfolios with closer target dates, equity security risks are more prevalent in this fund than in these other target-date funds. In addition to equity securities risk, the fund's other main risk factors are listed below in alphabetical order. &lt;i&gt;Before investing, be sure to read the additional descriptions of these risks beginning on page 78 of the prospectus.&lt;/i&gt;            
            &lt;/div&gt;

               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk based on the nature of their support.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;

               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;

               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;

               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;

               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;

               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;

               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;

Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide.

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;

In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;

               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;

               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;

               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;

               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;

               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;

               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The following information illustrates the variability of the fund's returns and provides some indication of the risks of investing in the fund by showing changes in the fund's performance from year to year and by showing how the fund's average annual returns compared with a broad-based market index. Past performance (before and after taxes) does not indicate future results. All figures assume dividend reinvestment. Performance information is updated daily, monthly, and quarterly and may be obtained at our website, jhinvestments.com, or by calling 800-225-5291 (Class A), Monday to Thursday, 8:00 A.M.&#8212;7:00 P.M., and Friday, 8:00 A.M.&#8212;6:00 P.M., Eastern time, or 888-972-8696 (Class I, Class R1, Class R2, Class R3, Class R4, Class R5, and Class R6) between 8:30 A.M. and 5:00 P.M., Eastern time, on most business days.&lt;/div&gt;

The information shows how the fund's performance compares with the returns of an index of funds with similar investment objectives. From December 1, 2016 to November 30, 2017, the Custom Benchmark consisted of the following indices and approximate weightings: 56.70% Russell 3000 Index, 24.30% MSCI ACWI ex-USA Index, 15.20% Bloomberg Barclays U.S. Aggregate Bond Index, and 3.80% ICE Bank of America Merrill Lynch U.S. High Yield Master II Index. The weightings of the indices in the Custom Benchmark are adjusted annually to reflect changes in the fund's target asset allocation in accordance with the annual roll-down of the glide path described above and differed in periods prior to December 1, 2016.&lt;/div&gt;

Class R6, Class R2, and Class I shares commenced operations on September 1, 2011, March 1, 2012, and March 27, 2015, respectively.  Returns prior to a class's commencement date are those of Class R1 shares. Returns for Class I, Class R2, and Class R6 shares would have been substantially similar to returns of Class R1 shares because each share class is invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.&lt;/div&gt;

Your actual after-tax returns may be different. After-tax returns are not relevant to shares held in an IRA, 401(k), or other tax-advantaged investment plan. After-tax returns for other share classes would vary.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 19% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests substantially all of its assets in underlying funds using an asset allocation strategy designed for investors expected to retire around the year 2035.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The portfolio managers of the fund allocate assets among the underlying funds according to an asset allocation strategy that becomes increasingly conservative over time. John Hancock Multimanager 2035 Lifetime Portfolio has a target asset allocation of 86% of its assets in underlying funds that invest primarily in equity securities. The fund will have a greater exposure to underlying funds that invest primarily in equity securities than will a John Hancock Multimanager Lifetime Portfolio with a closer target date. To reduce investment risk and volatility as retirement approaches and in the postretirement years, the asset allocation strategy will change over time according to a predetermined "glide path" shown in the following chart. The fund may be a primary source of income for its shareholders after retirement.&lt;/div&gt;         
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                  GLIDE PATH CHART               
               &lt;/b&gt;&lt;/div&gt;        
 &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;/div&gt;     
                     &lt;img alt="glidepath chart" src="glidepath.jpg"&gt;&lt;/img&gt;  
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The allocations reflected in the glide path are referred to as target allocations because they do not reflect active decisions made by the portfolio managers to produce an overweight or an underweight position in a particular asset class. The fund has a target allocation to underlying funds that invest in the broad asset classes of equity and fixed-income securities, but may also allocate its assets to underlying funds that invest outside these asset classes to protect the fund or help it achieve its objective. For example, the fund also typically allocates a portion of its assets to underlying funds that invest in alternative and specialty asset classes. The fund's allocation to alternative and specialty underlying funds may vary over time and in relation to a John Hancock Multimanager Lifetime Portfolio with a different target date. The managers may change the target allocation without shareholder approval if they believe that such change would benefit the fund and its shareholders. Under normal circumstances, any deviation from the target allocation is not expected to be greater than plus or minus 10%.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Within the prescribed percentage allocation, the managers select the percentage level to be maintained in specific underlying funds. New investments made by the fund may be directed to particular underlying funds in an effort to maintain the desired target allocations. There is no guarantee that the portfolio managers will correctly predict the market or economic conditions and, as with other mutual fund investments, you could lose money even if the fund is at or close to its designated retirement year or in its postretirement stage.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is designed for investors who may remain invested in the fund through their retirement years. The fund will continue to be managed according to an allocation strategy that becomes increasingly conservative over time until approximately twenty years after retirement, at which time the fund expects to maintain a static allocation of approximately 25% of its assets in equity underlying funds.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in underlying funds that invest in a broad range of equity, fixed-income and alternative/specialty securities and asset classes, including, but not limited to, U.S. and foreign securities, including emerging-market securities, commodities, asset-backed securities, small-cap securities, and below-investment-grade securities (i.e., junk bonds). The underlying funds may also use derivatives, such as swaps, foreign currency forwards, futures, and options, in each case for the purposes of reducing risk, obtaining efficient market exposure and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in various actively managed underlying funds that as a group hold a wide range of equity-type securities in their portfolios, including convertible securities. These include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. The fund may also invest in various passively managed underlying funds. Certain equity underlying funds may invest in initial public offerings (IPOs). Each of the equity underlying funds has its own investment strategy that, for example, may focus on growth stocks or value stocks, or may employ a strategy combining growth and income stocks, and/or may invest in derivatives such as credit default swaps, foreign currency forwards, interest rate swaps, options on securities, and futures contracts. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from shorter to longer term. The fixed-income underlying funds collectively hold various types of debt instruments such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging market securities). Certain underlying funds may invest in illiquid securities, and certain underlying funds may be non-diversified.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest directly in exchange-traded funds (ETFs), exchange-traded notes (ETNs), the securities of other investment companies, U.S. government securities, and other types of investments such as derivatives, including credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, in each case for the purposes of reducing risk, obtaining efficient market exposure, and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;To the extent permitted by law, the Board of Trustees of the fund may, in its discretion, determine to combine the fund with another fund without shareholder approval if the target allocation of the fund matches the target allocation of the other fund, although there is no assurance that the Board of Trustees will so determine at any point. The fund bears its own expenses and, in addition, indirectly bears its proportionate share of the expenses of the underlying funds in which it invests. The fund's performance reflects both the managers' allocation decisions and the performance of the underlying funds.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Many factors affect performance, and fund shares will fluctuate in price, meaning you could lose money. The fund's investment strategy may not produce the intended results.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;During periods of heightened market volatility or reduced liquidity, governments, their agencies, or other regulatory bodies, both within the United States and abroad, may take steps to intervene. These actions, which could include legislative, regulatory, or economic initiatives, might have unforeseeable consequences and could adversely affect the fund's performance or otherwise constrain the fund's ability to achieve its investment objective.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in equity securities than John Hancock Multimanager Lifetime Portfolios with closer target dates, equity security risks are more prevalent in this fund than in these other target-date funds. In addition to equity securities risk, the fund's other main risk factors are listed below in alphabetical order. &lt;i&gt;Before investing, be sure to read the additional descriptions of these risks beginning on page 78 of the prospectus.&lt;/i&gt;

               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk based on the nature of their support.&lt;/div&gt;

               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;

               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;

               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;

               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;

               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;

               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;

               &lt;b&gt;Lifecycle risk.&lt;/b&gt; Managers might not correctly predict market or economic conditions, and you could lose money even close to, during, or after the fund's designated retirement year.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Target allocation risk.&lt;/b&gt; The fund's risk profile will change due to reallocation or rebalancing of portfolio assets as the fund approaches its target date.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

Past performance (before and after taxes) does not indicate future results. All figures assume dividend reinvestment. Performance information is updated daily, monthly, and quarterly and may be obtained at our website, jhinvestments.com, or by calling 800-225-5291 (Class A), Monday to Thursday, 8:00 A.M.&#8212;7:00 P.M., and Friday, 8:00 A.M.&#8212;6:00 P.M., Eastern time, or 888-972-8696 (Class I, Class R1, Class R2, Class R3, Class R4, Class R5, and Class R6) between 8:30 A.M. and 5:00 P.M., Eastern time, on most business days.&lt;/div&gt;

The information shows how the fund's performance compares with the returns of an index of funds with similar investment objectives. From December 1, 2016 to November 30, 2017, the Custom Benchmark consisted of the following indices and approximate weightings: 62.30% Russell 3000 Index, 26.70% MSCI ACWI ex-USA Index, 8.80% Bloomberg Barclays U.S. Aggregate Bond Index, and 2.20% ICE Bank of America Merrill Lynch U.S. High Yield Master II Index. The weightings of the indices in the Custom Benchmark are adjusted annually to reflect changes in the fund's target asset allocation in accordance with the annual roll-down of the glide path described above and differed in periods prior to December 1, 2016.&lt;/div&gt;

Returns prior to a class's commencement date are those of Class R1 shares. Returns for Class I, Class R2, and Class R6 shares would have been substantially similar to returns of Class R1 shares because each share class is invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.&lt;/div&gt;

The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 19% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests substantially all of its assets in underlying funds using an asset allocation strategy designed for investors expected to retire around the year 2040.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The portfolio managers of the fund allocate assets among the underlying funds according to an asset allocation strategy that becomes increasingly conservative over time. John Hancock Multimanager 2040 Lifetime Portfolio has a target asset allocation of 93% of its assets in underlying funds that invest primarily in equity securities. The fund will have a greater exposure to underlying funds that invest primarily in equity securities than will a John Hancock Multimanager Lifetime Portfolio with a closer target date. To reduce investment risk and volatility as retirement approaches and in the postretirement years, the asset allocation strategy will change over time according to a predetermined "glide path" shown in the following chart. The fund may be a primary source of income for its shareholders after retirement.&lt;/div&gt;         
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                  GLIDE PATH CHART               
               &lt;/b&gt;&lt;/div&gt;             
                      &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;/div&gt;
                  &lt;img alt="glidepath chart" src="glidepath.jpg"&gt;&lt;/img&gt;  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The allocations reflected in the glide path are referred to as target allocations because they do not reflect active decisions made by the portfolio managers to produce an overweight or an underweight position in a particular asset class. The fund has a target allocation to underlying funds that invest in the broad asset classes of equity and fixed-income securities, but may also allocate its assets to underlying funds that invest outside these asset classes to protect the fund or help it achieve its objective. For example, the fund also typically allocates a portion of its assets to underlying funds that invest in alternative and specialty asset classes. The fund's allocation to alternative and specialty underlying funds may vary over time and in relation to a John Hancock Multimanager Lifetime Portfolio with a different target date. The managers may change the target allocation without shareholder approval if they believe that such change would benefit the fund and its shareholders. Under normal circumstances, any deviation from the target allocation is not expected to be greater than plus or minus 10%.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Within the prescribed percentage allocation, the managers select the percentage level to be maintained in specific underlying funds. New investments made by the fund may be directed to particular underlying funds in an effort to maintain the desired target allocations. There is no guarantee that the portfolio managers will correctly predict the market or economic conditions and, as with other mutual fund investments, you could lose money even if the fund is at or close to its designated retirement year or in its postretirement stage.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is designed for investors who may remain invested in the fund through their retirement years. The fund will continue to be managed according to an allocation strategy that becomes increasingly conservative over time until approximately twenty years after retirement, at which time the fund expects to maintain a static allocation of approximately 25% of its assets in equity underlying funds.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in underlying funds that invest in a broad range of equity, fixed-income and alternative/specialty securities and asset classes, including, but not limited to, U.S. and foreign securities, including emerging-market securities, commodities, asset-backed securities, small-cap securities, and below-investment-grade securities (i.e., junk bonds). The underlying funds may also use derivatives, such as swaps, foreign currency forwards, futures, and options, in each case for the purposes of reducing risk, obtaining efficient market exposure and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in various actively managed underlying funds that as a group hold a wide range of equity-type securities in their portfolios, including convertible securities. These include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. The fund may also invest in various passively managed underlying funds. Certain equity underlying funds may invest in initial public offerings (IPOs). Each of the equity underlying funds has its own investment strategy that, for example, may focus on growth stocks or value stocks, or may employ a strategy combining growth and income stocks, and/or may invest in derivatives such as credit default swaps, foreign currency forwards, interest rate swaps, options on securities, and futures contracts. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from shorter to longer term. The fixed-income underlying funds collectively hold various types of debt instruments such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging market securities). Certain underlying funds may invest in illiquid securities, and certain underlying funds may be non-diversified.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest directly in exchange-traded funds (ETFs), exchange-traded notes (ETNs), the securities of other investment companies, U.S. government securities, and other types of investments such as derivatives, including credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, in each case for the purposes of reducing risk, obtaining efficient market exposure, and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;To the extent permitted by law, the Board of Trustees of the fund may, in its discretion, determine to combine the fund with another fund without shareholder approval if the target allocation of the fund matches the target allocation of the other fund, although there is no assurance that the Board of Trustees will so determine at any point. The fund bears its own expenses and, in addition, indirectly bears its proportionate share of the expenses of the underlying funds in which it invests. The fund's performance reflects both the managers' allocation decisions and the performance of the underlying funds.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Many factors affect performance, and fund shares will fluctuate in price, meaning you could lose money. The fund's investment strategy may not produce the intended results.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;During periods of heightened market volatility or reduced liquidity, governments, their agencies, or other regulatory bodies, both within the United States and abroad, may take steps to intervene. These actions, which could include legislative, regulatory, or economic initiatives, might have unforeseeable consequences and could adversely affect the fund's performance or otherwise constrain the fund's ability to achieve its investment objective.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in equity securities than John Hancock Multimanager Lifetime Portfolios with closer target dates, equity security risks are more prevalent in this fund than in these other target-date funds. In addition to equity securities risk, the fund's other main risk factors are listed below in alphabetical order. &lt;i&gt;Before investing, be sure to read the additional descriptions of these risks beginning on page 78 of the prospectus.&lt;/i&gt;            
            &lt;/div&gt;

               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk based on the nature of their support.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;

               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;

               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;

               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;

               &lt;b&gt;Target allocation risk.&lt;/b&gt; The fund's risk profile will change due to reallocation or rebalancing of portfolio assets as the fund approaches its target date.&lt;/div&gt;

               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;

Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;

               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;

               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;

               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;

               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The following information illustrates the variability of the fund's returns and provides some indication of the risks of investing in the fund by showing changes in the fund's performance from year to year and by showing how the fund's average annual returns compared with a broad-based market index. Past performance (before and after taxes) does not indicate future results. All figures assume dividend reinvestment. Performance information is updated daily, monthly, and quarterly and may be obtained at our website, jhinvestments.com, or by calling 800-225-5291 (Class A), Monday to Thursday, 8:00 A.M.&#8212;7:00 P.M., and Friday, 8:00 A.M.&#8212;6:00 P.M., Eastern time, or 888-972-8696 (Class I, Class R1, Class R2, Class R3, Class R4, Class R5, and Class R6) between 8:30 A.M. and 5:00 P.M., Eastern time, on most business days.&lt;/div&gt;

The information shows how the fund's performance compares with the returns of an index of funds with similar investment objectives. From December 1, 2007 to November 30, 2017, the Custom Benchmark consisted of the following indices and approximate weightings: 66.50% Russell 3000 Index, 28.50% MSCI ACWI ex-USA Index, 4.00% Bloomberg Barclays U.S. Aggregate Bond Index, and 1.00% ICE Bank of America Merrill Lynch U.S. High Yield Master II Index. The weightings of the indices in the Custom Benchmark are adjusted annually to reflect changes in the fund's target asset allocation in accordance with the annual roll-down of the glide path described above and differed in periods prior to December 1, 2007.&lt;/div&gt;

Class R6, Class R2, and Class I shares commenced operations on September 1, 2011, March 1, 2012, and March 27, 2015, respectively.  Returns prior to a class's commencement date are those of Class R1 shares. Returns for Class I, Class R2, and Class R6 shares would have been substantially similar to returns of Class R1 shares because each share class is invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.&lt;/div&gt;

Your actual after-tax returns may be different. After-tax returns are not relevant to shares held in an IRA, 401(k), or other tax-advantaged investment plan. After-tax returns for other share classes would vary.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 19% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests substantially all of its assets in underlying funds using an asset allocation strategy designed for investors expected to retire around the year 2045.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The portfolio managers of the fund allocate assets among the underlying funds according to an asset allocation strategy that becomes increasingly conservative over time. John Hancock Multimanager 2045 Lifetime Portfolio has a target asset allocation of 95% of its assets in underlying funds that invest primarily in equity securities. The fund will have a greater exposure to underlying funds that invest primarily in equity securities than will a John Hancock Multimanager Lifetime Portfolio with a closer target date. To reduce investment risk and volatility as retirement approaches and in the postretirement years, the asset allocation strategy will change over time according to a predetermined "glide path" shown in the following chart. The fund may be a primary source of income for its shareholders after retirement.&lt;/div&gt;          
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                  GLIDE PATH CHART               
               &lt;/b&gt;&lt;/div&gt;  
 &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;/div&gt;           
                     &lt;img alt="glidepath chart" src="glidepath.jpg"&gt;&lt;/img&gt;  
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The allocations reflected in the glide path are referred to as target allocations because they do not reflect active decisions made by the portfolio managers to produce an overweight or an underweight position in a particular asset class. The fund has a target allocation to underlying funds that invest in the broad asset classes of equity and fixed-income securities, but may also allocate its assets to underlying funds that invest outside these asset classes to protect the fund or help it achieve its objective. For example, the fund also typically allocates a portion of its assets to underlying funds that invest in alternative and specialty asset classes. The fund's allocation to alternative and specialty underlying funds may vary over time and in relation to a John Hancock Multimanager Lifetime Portfolio with a different target date. The managers may change the target allocation without shareholder approval if they believe that such change would benefit the fund and its shareholders. Under normal circumstances, any deviation from the target allocation is not expected to be greater than plus or minus 10%.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Within the prescribed percentage allocation, the managers select the percentage level to be maintained in specific underlying funds. New investments made by the fund may be directed to particular underlying funds in an effort to maintain the desired target allocations. There is no guarantee that the portfolio managers will correctly predict the market or economic conditions and, as with other mutual fund investments, you could lose money even if the fund is at or close to its designated retirement year or in its postretirement stage.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is designed for investors who may remain invested in the fund through their retirement years. The fund will continue to be managed according to an allocation strategy that becomes increasingly conservative over time until approximately twenty years after retirement, at which time the fund expects to maintain a static allocation of approximately 25% of its assets in equity underlying funds.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in underlying funds that invest in a broad range of equity, fixed-income and alternative/specialty securities and asset classes, including, but not limited to, U.S. and foreign securities, including emerging-market securities, commodities, asset-backed securities, small-cap securities, and below-investment-grade securities (i.e., junk bonds). The underlying funds may also use derivatives, such as swaps, foreign currency forwards, futures, and options, in each case for the purposes of reducing risk, obtaining efficient market exposure and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in various actively managed underlying funds that as a group hold a wide range of equity-type securities in their portfolios, including convertible securities. These include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. The fund may also invest in various passively managed underlying funds. Certain equity underlying funds may invest in initial public offerings (IPOs). Each of the equity underlying funds has its own investment strategy that, for example, may focus on growth stocks or value stocks, or may employ a strategy combining growth and income stocks, and/or may invest in derivatives such as credit default swaps, foreign currency forwards, interest rate swaps, options on securities, and futures contracts. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from shorter to longer term. The fixed-income underlying funds collectively hold various types of debt instruments such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging market securities). Certain underlying funds may invest in illiquid securities, and certain underlying funds may be non-diversified.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest directly in exchange-traded funds (ETFs), exchange-traded notes (ETNs), the securities of other investment companies, U.S. government securities, and other types of investments such as derivatives, including credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, in each case for the purposes of reducing risk, obtaining efficient market exposure, and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;To the extent permitted by law, the Board of Trustees of the fund may, in its discretion, determine to combine the fund with another fund without shareholder approval if the target allocation of the fund matches the target allocation of the other fund, although there is no assurance that the Board of Trustees will so determine at any point. The fund bears its own expenses and, in addition, indirectly bears its proportionate share of the expenses of the underlying funds in which it invests. The fund's performance reflects both the managers' allocation decisions and the performance of the underlying funds.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Many factors affect performance, and fund shares will fluctuate in price, meaning you could lose money. The fund's investment strategy may not produce the intended results.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;During periods of heightened market volatility or reduced liquidity, governments, their agencies, or other regulatory bodies, both within the United States and abroad, may take steps to intervene. These actions, which could include legislative, regulatory, or economic initiatives, might have unforeseeable consequences and could adversely affect the fund's performance or otherwise constrain the fund's ability to achieve its investment objective.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in equity securities than John Hancock Multimanager Lifetime Portfolios with closer target dates, equity security risks are more prevalent in this fund than in these other target-date funds. In addition to equity securities risk, the fund's other main risk factors are listed below in alphabetical order. &lt;i&gt;Before investing, be sure to read the additional descriptions of these risks beginning on page 78 of the prospectus.&lt;/i&gt;

               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk based on the nature of their support.&lt;/div&gt;

               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;

               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;

The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors.

               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;

               &lt;b&gt;Target allocation risk.&lt;/b&gt; The fund's risk profile will change due to reallocation or rebalancing of portfolio assets as the fund approaches its target date.&lt;/div&gt;

               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;

               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The following information illustrates the variability of the fund's returns and provides some indication of the risks of investing in the fund by showing changes in the fund's performance from year to year and by showing how the fund's average annual returns compared with a broad-based market index. Past performance (before and after taxes) does not indicate future results. All figures assume dividend reinvestment. Performance information is updated daily, monthly, and quarterly and may be obtained at our website, jhinvestments.com, or by calling 800-225-5291 (Class A), Monday to Thursday, 8:00 A.M.&#8212;7:00 P.M., and Friday, 8:00 A.M.&#8212;6:00 P.M., Eastern time, or 888-972-8696 (Class I, Class R1, Class R2, Class R3, Class R4, Class R5, and Class R6) between 8:30 A.M. and 5:00 P.M., Eastern time, on most business days.&lt;/div&gt;

The information shows how the fund's performance compares with the returns of an index of funds with similar investment objectives. From December 1, 2007 to November 30, 2017, the Custom Benchmark consisted of the following indices and approximate weightings: 66.50% Russell 3000 Index, 28.50% MSCI ACWI ex-USA Index, 4.00% Bloomberg Barclays U.S. Aggregate Bond Index, and 1.00% ICE Bank of America Merrill Lynch U.S. High Yield Master II Index. The weightings of the indices in the Custom Benchmark are adjusted annually to reflect changes in the fund's target asset allocation in accordance with the annual roll-down of the glide path described above and differed in periods prior to December 1, 2007.&lt;/div&gt;

Returns prior to a class's commencement date are those of Class R1 shares. Returns for Class I, Class R2, and Class R6 shares would have been substantially similar to returns of Class R1 shares because each share class is invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.&lt;/div&gt;

Your actual after-tax returns may be different. After-tax returns are not relevant to shares held in an IRA, 401(k), or other tax-advantaged investment plan.

The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 18% of the average value of its portfolio.&lt;/div&gt;

The fund will have a greater exposure to underlying funds that invest primarily in equity securities than will a John Hancock Multimanager Lifetime Portfolio with a closer target date. To reduce investment risk and volatility as retirement approaches and in the postretirement years, the asset allocation strategy will change over time according to a predetermined "glide path" shown in the following chart.

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The allocations reflected in the glide path are referred to as target allocations because they do not reflect active decisions made by the portfolio managers to produce an overweight or an underweight position in a particular asset class. The fund has a target allocation to underlying funds that invest in the broad asset classes of equity and fixed-income securities, but may also allocate its assets to underlying funds that invest outside these asset classes to protect the fund or help it achieve its objective. For example, the fund also typically allocates a portion of its assets to underlying funds that invest in alternative and specialty asset classes. The fund's allocation to alternative and specialty underlying funds may vary over time and in relation to a John Hancock Multimanager Lifetime Portfolio with a different target date. The managers may change the target allocation without shareholder approval if they believe that such change would benefit the fund and its shareholders. Under normal circumstances, any deviation from the target allocation is not expected to be greater than plus or minus 10%.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Within the prescribed percentage allocation, the managers select the percentage level to be maintained in specific underlying funds. New investments made by the fund may be directed to particular underlying funds in an effort to maintain the desired target allocations. There is no guarantee that the portfolio managers will correctly predict the market or economic conditions and, as with other mutual fund investments, you could lose money even if the fund is at or close to its designated retirement year or in its postretirement stage.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is designed for investors who may remain invested in the fund through their retirement years. The fund will continue to be managed according to an allocation strategy that becomes increasingly conservative over time until approximately twenty years after retirement, at which time the fund expects to maintain a static allocation of approximately 25% of its assets in equity underlying funds.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in underlying funds that invest in a broad range of equity, fixed-income and alternative/specialty securities and asset classes, including, but not limited to, U.S. and foreign securities, including emerging-market securities, commodities, asset-backed securities, small-cap securities, and below-investment-grade securities (i.e., junk bonds). The underlying funds may also use derivatives, such as swaps, foreign currency forwards, futures, and options, in each case for the purposes of reducing risk, obtaining efficient market exposure and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in various actively managed underlying funds that as a group hold a wide range of equity-type securities in their portfolios, including convertible securities. These include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. The fund may also invest in various passively managed underlying funds. Certain equity underlying funds may invest in initial public offerings (IPOs). Each of the equity underlying funds has its own investment strategy that, for example, may focus on growth stocks or value stocks, or may employ a strategy combining growth and income stocks, and/or may invest in derivatives such as credit default swaps, foreign currency forwards, interest rate swaps, options on securities, and futures contracts. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from shorter to longer term. The fixed-income underlying funds collectively hold various types of debt instruments such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging market securities). Certain underlying funds may invest in illiquid securities, and certain underlying funds may be non-diversified.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest directly in exchange-traded funds (ETFs), exchange-traded notes (ETNs), the securities of other investment companies, U.S. government securities, and other types of investments such as derivatives, including credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, in each case for the purposes of reducing risk, obtaining efficient market exposure, and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;To the extent permitted by law, the Board of Trustees of the fund may, in its discretion, determine to combine the fund with another fund without shareholder approval if the target allocation of the fund matches the target allocation of the other fund, although there is no assurance that the Board of Trustees will so determine at any point. The fund bears its own expenses and, in addition, indirectly bears its proportionate share of the expenses of the underlying funds in which it invests. The fund's performance reflects both the managers' allocation decisions and the performance of the underlying funds.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Many factors affect performance, and fund shares will fluctuate in price, meaning you could lose money. The fund's investment strategy may not produce the intended results.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;During periods of heightened market volatility or reduced liquidity, governments, their agencies, or other regulatory bodies, both within the United States and abroad, may take steps to intervene. These actions, which could include legislative, regulatory, or economic initiatives, might have unforeseeable consequences and could adversely affect the fund's performance or otherwise constrain the fund's ability to achieve its investment objective.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in equity securities than John Hancock Multimanager Lifetime Portfolios with closer target dates, equity security risks are more prevalent in this fund than in these other target-date funds. In addition to equity securities risk, the fund's other main risk factors are listed below in alphabetical order. &lt;i&gt;Before investing, be sure to read the additional descriptions of these risks beginning on page 78 of the prospectus.&lt;/i&gt;            
            &lt;/div&gt;

               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk based on the nature of their support.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;

               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;

               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;

               &lt;b&gt;Target allocation risk.&lt;/b&gt; The fund's risk profile will change due to reallocation or rebalancing of portfolio assets as the fund approaches its target date.&lt;/div&gt;

               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance.

               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;

               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;

               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The following information illustrates the variability of the fund's returns and provides some indication of the risks of investing in the fund by showing changes in the fund's performance from year to year and by showing how the fund's average annual returns compared with a broad-based market index. Past performance (before and after taxes) does not indicate future results. All figures assume dividend reinvestment. Performance information is updated daily, monthly, and quarterly and may be obtained at our website, jhinvestments.com, or by calling 800-225-5291 (Class A), Monday to Thursday, 8:00 A.M.&#8212;7:00 P.M., and Friday, 8:00 A.M.&#8212;6:00 P.M., Eastern time, or 888-972-8696 (Class I, Class R1, Class R2, Class R3, Class R4, Class R5, and Class R6) between 8:30 A.M. and 5:00 P.M., Eastern time, on most business days.&lt;/div&gt;

The information shows how the fund's performance compares with the returns of an index of funds with similar investment objectives. From April 29, 2011 to November 30, 2017, the Custom Benchmark consisted of the following indices and approximate weightings: 66.50% Russell 3000 Index, 28.50% MSCI ACWI ex-USA Index, 4.00% Bloomberg Barclays U.S. Aggregate Bond Index, and 1.00% ICE Bank of America Merrill Lynch U.S. High Yield Master II Index. The weightings of the indices in the Custom Benchmark are adjusted annually to reflect changes in the fund's target asset allocation in accordance with the annual roll-down of the glide path described above.&lt;/div&gt;

Class A, Class R1, Class R2, Class R3, Class R4, Class R5, and Class R6 shares commenced operations on March 1, 2012. Returns prior to a class's commencement date are those of Class 1 shares, except that they include any sales charges. Returns for Class A, Class I, Class R1, Class R2, Class R3, Class R4, Class R5, and Class R6 shares would have been substantially similar to returns of Class 1 shares because each share class is invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.&lt;/div&gt;

Your actual after-tax returns may be different. After-tax returns are not relevant to shares held in an IRA, 401(k), or other tax-advantaged investment plan. After-tax returns for other share classes would vary.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 14% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests substantially all of its assets in underlying funds using an asset allocation strategy designed for investors expected to retire around the year 2055.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The portfolio managers of the fund allocate assets among the underlying funds according to an asset allocation strategy that becomes increasingly conservative over time. John Hancock Multimanager 2055 Lifetime Portfolio has a target asset allocation of 95% of its assets in underlying funds that invest primarily in equity securities. The fund will have a greater exposure to underlying funds that invest primarily in equity securities than will a John Hancock Multimanager Lifetime Portfolio with a closer target date. To reduce investment risk and volatility as retirement approaches and in the postretirement years, the asset allocation strategy will change over time according to a predetermined "glide path" shown in the following chart. The fund may be a primary source of income for its shareholders after retirement.&lt;/div&gt;          
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                  GLIDE PATH CHART               
               &lt;/b&gt;&lt;/div&gt;     
 &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;/div&gt;        
                     &lt;img alt="glidepath chart" src="glidepath.jpg"&gt;&lt;/img&gt;  
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The allocations reflected in the glide path are referred to as target allocations because they do not reflect active decisions made by the portfolio managers to produce an overweight or an underweight position in a particular asset class. The fund has a target allocation to underlying funds that invest in the broad asset classes of equity and fixed-income securities, but may also allocate its assets to underlying funds that invest outside these asset classes to protect the fund or help it achieve its objective. For example, the fund also typically allocates a portion of its assets to underlying funds that invest in alternative and specialty asset classes. The fund's allocation to alternative and specialty underlying funds may vary over time and in relation to a John Hancock Multimanager Lifetime Portfolio with a different target date. The managers may change the target allocation without shareholder approval if they believe that such change would benefit the fund and its shareholders. Under normal circumstances, any deviation from the target allocation is not expected to be greater than plus or minus 10%.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Within the prescribed percentage allocation, the managers select the percentage level to be maintained in specific underlying funds. New investments made by the fund may be directed to particular underlying funds in an effort to maintain the desired target allocations. There is no guarantee that the portfolio managers will correctly predict the market or economic conditions and, as with other mutual fund investments, you could lose money even if the fund is at or close to its designated retirement year or in its postretirement stage.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is designed for investors who may remain invested in the fund through their retirement years. The fund will continue to be managed according to an allocation strategy that becomes increasingly conservative over time until approximately twenty years after retirement, at which time the fund expects to maintain a static allocation of approximately 25% of its assets in equity underlying funds.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in underlying funds that invest in a broad range of equity, fixed-income and alternative/specialty securities and asset classes, including, but not limited to, U.S. and foreign securities, including emerging-market securities, commodities, asset-backed securities, small-cap securities, and below-investment-grade securities (i.e., junk bonds). The underlying funds may also use derivatives, such as swaps, foreign currency forwards, futures, and options, in each case for the purposes of reducing risk, obtaining efficient market exposure and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in various actively managed underlying funds that as a group hold a wide range of equity-type securities in their portfolios, including convertible securities. These include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. The fund may also invest in various passively managed underlying funds. Certain equity underlying funds may invest in initial public offerings (IPOs). Each of the equity underlying funds has its own investment strategy that, for example, may focus on growth stocks or value stocks, or may employ a strategy combining growth and income stocks, and/or may invest in derivatives such as credit default swaps, foreign currency forwards, interest rate swaps, options on securities, and futures contracts. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from shorter to longer term. The fixed-income underlying funds collectively hold various types of debt instruments such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging market securities). Certain underlying funds may invest in illiquid securities, and certain underlying funds may be non-diversified.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest directly in exchange-traded funds (ETFs), exchange-traded notes (ETNs), the securities of other investment companies, U.S. government securities, and other types of investments such as derivatives, including credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, in each case for the purposes of reducing risk, obtaining efficient market exposure, and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;To the extent permitted by law, the Board of Trustees of the fund may, in its discretion, determine to combine the fund with another fund without shareholder approval if the target allocation of the fund matches the target allocation of the other fund, although there is no assurance that the Board of Trustees will so determine at any point. The fund bears its own expenses and, in addition, indirectly bears its proportionate share of the expenses of the underlying funds in which it invests. The fund's performance reflects both the managers' allocation decisions and the performance of the underlying funds.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Many factors affect performance, and fund shares will fluctuate in price, meaning you could lose money. The fund's investment strategy may not produce the intended results.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;During periods of heightened market volatility or reduced liquidity, governments, their agencies, or other regulatory bodies, both within the United States and abroad, may take steps to intervene. These actions, which could include legislative, regulatory, or economic initiatives, might have unforeseeable consequences and could adversely affect the fund's performance or otherwise constrain the fund's ability to achieve its investment objective.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in equity securities than John Hancock Multimanager Lifetime Portfolios with closer target dates, equity security risks are more prevalent in this fund than in these other target-date funds. In addition to equity securities risk, the fund's other main risk factors are listed below in alphabetical order. &lt;i&gt;Before investing, be sure to read the additional descriptions of these risks beginning on page 78 of the prospectus.&lt;/i&gt;

               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk based on the nature of their support.&lt;/div&gt;

               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;

               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;

               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;

               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;

               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;

               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;

               &lt;b&gt;Target allocation risk.&lt;/b&gt; The fund's risk profile will change due to reallocation or rebalancing of portfolio assets as the fund approaches its target date.&lt;/div&gt;

               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The following information illustrates the variability of the fund's returns and provides some indication of the risks of investing in the fund by showing changes in the fund's performance from year to year and by showing how the fund's average annual returns compared with a broad-based market index. Past performance (before and after taxes) does not indicate future results. All figures assume dividend reinvestment. Performance information is updated daily, monthly, and quarterly and may be obtained at our website, jhinvestments.com, or by calling 800-225-5291 (Class A), Monday to Thursday, 8:00 A.M.&#8212;7:00 P.M., and Friday, 8:00 A.M.&#8212;6:00 P.M., Eastern time, or 888-972-8696 (Class I, Class R1, Class R2, Class R3, Class R4, Class R5, and Class R6) between 8:30 A.M. and 5:00 P.M., Eastern time, on most business days.&lt;/div&gt;

The information shows how the fund's performance compares with the returns of an index of funds with similar investment objectives. From March 26, 2014 to November 30, 2017, the Custom Benchmark consisted of the following indices and approximate weightings: 66.50% Russell 3000 Index, 28.50% MSCI ACWI ex-USA Index, 4.00% Bloomberg Barclays U.S. Aggregate Bond Index, and 1.00% ICE Bank of America Merrill Lynch U.S. High Yield Master II Index. The weightings of the indices in the Custom Benchmark are adjusted annually to reflect changes in the fund's target asset allocation in accordance with the annual roll down of the glide path described above.&lt;/div&gt;

Returns prior to a class's commencement date are those of Class R1 shares. Returns for Class I shares would have been substantially similar to returns of Class R1 shares because each share class is invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.&lt;/div&gt;

Your actual after-tax returns may be different. After-tax returns are not relevant to shares held in an IRA, 401(k), or other tax-advantaged investment plan.

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 21% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests substantially all of its assets in underlying funds using an asset allocation strategy designed for investors expected to retire around the year 2060.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The portfolio managers of the fund allocate assets among the underlying funds according to an asset allocation strategy that becomes increasingly conservative over time. John Hancock Multimanager 2060 Lifetime Portfolio has a target asset allocation of 95% of its assets in underlying funds that invest primarily in equity securities. The fund will have a greater exposure to underlying funds that invest primarily in equity securities than will a John Hancock Multimanager Lifetime Portfolio with a closer target date. To reduce investment risk and volatility as retirement approaches and in the postretirement years, the asset allocation strategy will change over time according to a predetermined "glide path" shown in the following chart. The fund may be a primary source of income for its shareholders after retirement.&lt;/div&gt;          
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                  GLIDE PATH CHART               
               &lt;/b&gt;&lt;/div&gt;             
          &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;/div&gt;            
                  &lt;img alt="glidepath chart" src="glidepath.jpg"&gt;&lt;/img&gt;  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The allocations reflected in the glide path are referred to as target allocations because they do not reflect active decisions made by the portfolio managers to produce an overweight or an underweight position in a particular asset class. The fund has a target allocation to underlying funds that invest in the broad asset classes of equity and fixed-income securities, but may also allocate its assets to underlying funds that invest outside these asset classes to protect the fund or help it achieve its objective. For example, the fund also typically allocates a portion of its assets to underlying funds that invest in alternative and specialty asset classes. The fund's allocation to alternative and specialty underlying funds may vary over time and in relation to a John Hancock Multimanager Lifetime Portfolio with a different target date. The managers may change the target allocation without shareholder approval if they believe that such change would benefit the fund and its shareholders. Under normal circumstances, any deviation from the target allocation is not expected to be greater than plus or minus 10%.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Within the prescribed percentage allocation, the managers select the percentage level to be maintained in specific underlying funds. New investments made by the fund may be directed to particular underlying funds in an effort to maintain the desired target allocations. There is no guarantee that the portfolio managers will correctly predict the market or economic conditions and, as with other mutual fund investments, you could lose money even if the fund is at or close to its designated retirement year or in its postretirement stage.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is designed for investors who may remain invested in the fund through their retirement years. The fund will continue to be managed according to an allocation strategy that becomes increasingly conservative over time until approximately twenty years after retirement, at which time the fund expects to maintain a static allocation of approximately 25% of its assets in equity underlying funds.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in underlying funds that invest in a broad range of equity, fixed-income and alternative/specialty securities and asset classes, including, but not limited to, U.S. and foreign securities, including emerging-market securities, commodities, asset-backed securities, small-cap securities, and below-investment-grade securities (i.e., junk bonds). The underlying funds may also use derivatives, such as swaps, foreign currency forwards, futures, and options, in each case for the purposes of reducing risk, obtaining efficient market exposure and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in various actively managed underlying funds that as a group hold a wide range of equity-type securities in their portfolios, including convertible securities. These include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. The fund may also invest in various passively managed underlying funds. Certain equity underlying funds may invest in initial public offerings (IPOs). Each of the equity underlying funds has its own investment strategy that, for example, may focus on growth stocks or value stocks, or may employ a strategy combining growth and income stocks, and/or may invest in derivatives such as credit default swaps, foreign currency forwards, interest rate swaps, options on securities, and futures contracts. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from shorter to longer term. The fixed-income underlying funds collectively hold various types of debt instruments such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging market securities). Certain underlying funds may invest in illiquid securities, and certain underlying funds may be non-diversified.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest directly in exchange-traded funds (ETFs), exchange-traded notes (ETNs), the securities of other investment companies, U.S. government securities, and other types of investments such as derivatives, including credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, in each case for the purposes of reducing risk, obtaining efficient market exposure, and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;To the extent permitted by law, the Board of Trustees of the fund may, in its discretion, determine to combine the fund with another fund without shareholder approval if the target allocation of the fund matches the target allocation of the other fund, although there is no assurance that the Board of Trustees will so determine at any point. The fund bears its own expenses and, in addition, indirectly bears its proportionate share of the expenses of the underlying funds in which it invests. The fund's performance reflects both the managers' allocation decisions and the performance of the underlying funds.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Many factors affect performance, and fund shares will fluctuate in price, meaning you could lose money. The fund's investment strategy may not produce the intended results.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;During periods of heightened market volatility or reduced liquidity, governments, their agencies, or other regulatory bodies, both within the United States and abroad, may take steps to intervene. These actions, which could include legislative, regulatory, or economic initiatives, might have unforeseeable consequences and could adversely affect the fund's performance or otherwise constrain the fund's ability to achieve its investment objective.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in equity securities than John Hancock Multimanager Lifetime Portfolios with closer target dates, equity security risks are more prevalent in this fund than in these other target-date funds. In addition to equity securities risk, the fund's other main risk factors are listed below in alphabetical order. &lt;i&gt;Before investing, be sure to read the additional descriptions of these risks beginning on page 78 of the prospectus.&lt;/i&gt;

               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk based on the nature of their support.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Investment company securities risk.&lt;/b&gt; A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lifecycle risk.&lt;/b&gt; Managers might not correctly predict market or economic conditions, and you could lose money even close to, during, or after the fund's designated retirement year.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Target allocation risk.&lt;/b&gt; The fund's risk profile will change due to reallocation or rebalancing of portfolio assets as the fund approaches its target date.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality.

Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's performance. During its most recent fiscal year, the fund's portfolio turnover rate was 52% of the average value of its portfolio.&lt;/div&gt;

The market-capitalization of individual portfolio securities and the fund's portfolio as a whole will vary over time as market conditions change.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund invests in equity securities, including common stock, preferred stock and equity-equivalent securities or instruments whose values are based on common stocks, such as convertible securities, rights, warrants or options (stock or stock index), futures contracts (stock or stock index), and index swaps.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund employs a multi style and multi manager approach in which portions of the fund's assets are allocated to different managers that employ distinct investment styles. The fund currently has three managers. The fund's advisor provides or oversees the provision of all investment advisory and portfolio management services for the fund, including overseeing the investment allocation for the fund and managing the fund's overall portfolio characteristics, including investment style exposures.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The advisor selects managers for the fund, allocates fund assets among and oversees those managers, and evaluates their performance results. The managers select the individual portfolio securities for the assets assigned to them. The advisor considers various characteristics of the manager's portfolio when allocating assets: market capitalization, growth and profitability, valuation, sector weightings, and earnings and price volatility. The advisor also considers the correlation between the managers' historical and expected investment returns. Since the advisor will rebalance the fund only periodically, the actual portion of the fund managed by each manager at any given time will vary.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in and potentially emphasize any economic sector. The fund may also invest in growth or value equity securities. Growth securities are securities a manager believes will experience relatively rapid earnings growth. Value securities, on the other hand, are securities a manager believes are selling at prices below their fundamental value.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund also may invest in: (a) securities of foreign issuers, including foreign issuers located in emerging markets, either directly through investments in foreign currency-denominated securities traded outside of the United States or indirectly through depositary receipts; (b) real estate investment trusts (REITs); (c) initial public offerings (IPOs); and (d) master limited partnerships (MLPs). The fund may invest in derivatives such as swaps, options, futures contracts, or options on futures contracts to gain market exposure, to adjust market exposure, or to maintain liquidity to pay redemptions. The fund may invest in foreign currency forward contracts to manage the fund's exposure to foreign currency. The fund also may invest in investment companies, including exchange-traded funds (ETFs) for the purpose of gaining exposure to equity markets while maintaining liquidity.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Many factors affect performance, and fund shares will fluctuate in price, meaning you could lose money. The fund's investment strategy may not produce the intended results.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;During periods of heightened market volatility or reduced liquidity, governments, their agencies, or other regulatory bodies, both within the United States and abroad, may take steps to intervene. These actions, which could include legislative, regulatory, or economic initiatives, might have unforeseeable consequences and could adversely affect the fund's performance or otherwise constrain the fund's ability to achieve its investment objective.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund's main risks are listed below in alphabetical order. &lt;i&gt;Before investing, be sure to read the additional descriptions of these risks beginning on page 8 of the prospectus.&lt;/i&gt;            
            &lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: foreign currency forward contracts, futures contracts, options on futures, options, and swaps. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Investment company securities risk.&lt;/b&gt; A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Master limited partnership risk.&lt;/b&gt; MLPs generally reflect the risks associated with their underlying assets and with pooled investment vehicles. MLPs with credit-related holdings are subject to interest-rate risk and risk of default.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Multi manager risk.&lt;/b&gt; The management teams' investment styles may not complement each other as intended. A multi manager approach could result in more exposure to certain types of securities and higher portfolio turnover.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Real estate investment trust risk.&lt;/b&gt; REITs, pooled investment vehicles that typically invest in real estate directly or in loans collateralized by real estate, carry risks associated with owning real estate, including the potential for a decline in value due to economic or market conditions.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Real estate securities risk.&lt;/b&gt; Securities of companies in the real estate industry carry risks associated with owning real estate, including the potential for a decline in value due to economic or market conditions.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized (including microcap) companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Warrants risk.&lt;/b&gt; The prices of warrants may not precisely reflect the prices of their underlying securities. Warrant holders do not receive dividends or have voting or credit rights. A warrant ceases to have value if not exercised prior to its expiration date.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The following information illustrates the variability of the fund's returns and provides some indication of the risks of investing in the fund by showing changes in the fund's performance from year to year and by showing how the fund's average annual returns compared with a broad-based market index. Past performance (before and after taxes) does not indicate future results. All figures assume dividend reinvestment. Performance information is updated daily, monthly, and quarterly and may be obtained at our website, jhinvestments.com, or by calling 800-225-5291 (Class A and Class C), Monday to Thursday, 8:00 A.M.&#8212;7:00 P.M., and Friday, 8:00 A.M.&#8212;6:00 P.M., Eastern time , or 888-972-8696 (Class I, Class R1, Class R2, Class R3, Class R4, Class R5, and Class R6) between 8:30 A.M. and 5:00 P.M., Eastern time, on most business days.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Prior to September 27, 2014, the fund was managed solely by Dimensional Fund Advisors LP (Dimensional) and another subadvisor pursuant to a different investment strategy.  The performance presented prior to this date should not be attributed to Brandywine Global Investment Management, LLC (Brandywine) or GW&amp;amp;K Investment Management, LLC (GW&amp;amp;K).&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Effective June 1, 2015, the fund eliminated its policy of investing at least 80% of its net assets (plus any borrowings for investment purposes) in equity securities of small-capitalization companies and adopted other investment strategy changes. The performance information presented for periods prior to June 1, 2015, reflects management of the fund consistent with investment strategies in effect during those periods (and without Brandywine and GW&amp;amp;K) and might have been different if the fund's investments had been managed under its current investment strategies by all of its current managers.&lt;/div&gt;

Returns shown prior to a class's commencement date are those of Class NAV shares, except that they include any sales charges. Returns for Class A, Class C, Class I, Class R1, Class R2, Class R3, Class R4, Class R5, and Class R6 shares would have been substantially similar to returns of Class NAV shares because each share class is invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.&lt;/div&gt;

Your actual after-tax returns may be different. After-tax returns are not relevant to shares held in an IRA, 401(k), or other tax-advantaged investment plan. After-tax returns for other share classes would vary.&lt;/div&gt;

Please see below a hypothetical example showing the expenses of a $10,000 investment for the time periods indicated and then, except as shown below, assuming you sell all of your shares at the end of those periods. The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's performance. During its most recent fiscal year, the fund's portfolio turnover rate was 165% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal circumstances, the fund seeks to achieve its investment objective by investing at least 80% of its net assets (plus any borrowings for investment purposes) in stocks of small-cap companies. The fund defines small-cap companies as those that, at the time of initial purchase, have a market capitalization equal to or less than the largest company in the Russell 2000 Growth Index (approximately $6.5 billion as of October 31, 2018). The fund invests mainly in common stocks, but it may also invest in exchange-traded funds (ETFs) to a limited extent, generally for purposes of gaining temporary market exposure.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The manager employs a growth-oriented investment philosophy to analyze and select investments and seeks to own stocks of high quality companies (based on such characteristics as return-on-equity or profitability) trading at what the manager believes are attractive valuations and that are experiencing positive earnings revisions. The manager seeks to invest in companies that it believes could experience future growth rates at levels higher than the Russell 2000 Growth Index. The manager utilizes an investment process that incorporates proprietary quantitative and qualitative research.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The manager continuously monitors and evaluates its investments and attempts to mitigate risk through ownership of a well-diversified portfolio. The fund may focus its investments in a particular sector or sectors of the economy and its exposures may vary significantly from the Russell 2000 Growth Index. The fund may invest up to 10% of its total assets in foreign securities, including those in emerging markets, and may invest in initial public offerings (IPOs). The manager defines emerging markets countries as those countries included in the MSCI Emerging Markets Index.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The manager will generally sell a stock if it determines, among other things, there has been an adverse change in the company's fundamentals, competitive position, or change to its relative valuation.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Due to its investment strategy, the fund may buy and sell securities frequently, which may result in high transaction costs and additional shareholder expenses.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Many factors affect performance, and fund shares will fluctuate in price, meaning you could lose money. The fund's investment strategy may not produce the intended results.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;During periods of heightened market volatility or reduced liquidity, governments, their agencies, or other regulatory bodies, both within the United States and abroad, may take steps to intervene. These actions, which could include legislative, regulatory, or economic initiatives, might have unforeseeable consequences and could adversely affect the fund's performance or otherwise constrain the fund's ability to achieve its investment objective.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund's main risks are listed below in alphabetical order. &lt;i&gt;Before investing, be sure to read the additional descriptions of these risks beginning on page 5 of the prospectus.&lt;/i&gt;            
            &lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations.&lt;/div&gt;

               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;High portfolio turnover risk.&lt;/b&gt; Trading securities actively and frequently can increase transaction costs (thus lowering performance) and taxable distributions.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small company risk.&lt;/b&gt; Small companies are generally less established and may be more volatile than larger companies. Small-capitalization securities may underperform the market as a whole.&lt;/div&gt;

Past performance (before and after taxes) does not indicate future results. All figures assume dividend reinvestment. Performance information is updated daily, monthly, and quarterly and may be obtained at our website, jhinvestments.com, or by calling 800-225-5291 (Class A and Class C), Monday to Thursday, 8:00 A.M.&#8212;7:00 P.M., and Friday, 8:00 A.M.&#8212;6:00 P.M., Eastern time, or 888-972-8696 (Class I and Class R6) between 8:30 A.M. and 5:00 P.M., Eastern time, on most business days.&lt;/div&gt;

Returns shown prior to a class's commencement date are those of Class NAV shares, except that they include any sales charges. Returns for Class A, Class C, Class I, and Class R6 shares would have been substantially similar to returns of Class NAV shares because each share class is invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.&lt;/div&gt;

The performance presented prior to this date should not be attributed to Redwood Investments, LLC, the fund's current subadvisor (Redwood). The performance information presented for periods prior to December 26, 2017 reflects management of the fund consistent with investment strategies in effect during those periods and might have been different if the fund's investments had been managed under its current investment strategies by Redwood.&lt;/div&gt;

More information about these and other discounts is available from your financial representative and on pages 16 to 18 of this prospectus under "Sales charge reductions and waivers" or pages 273 to 277 of the fund's Statement of Additional Information under "Sales Charges on Class A, Class B, and Class C Shares."&lt;/div&gt;

Please see below a hypothetical example showing the expenses of a $10,000 investment for the time periods indicated and then assuming you sell all of your shares at the end of those periods. The example assumes a 5% average annual return and that fund expenses will not change over the periods.

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's performance. During its most recent fiscal year, the fund's portfolio turnover rate was 25% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in small-cap companies that are believed to be undervalued by various measures and offer good prospects for capital appreciation. The fund defines small-cap companies as those with market capitalizations at or below the market capitalization of the largest company represented in either the Russell 2000 Value Index (approximately $5.4 billion as of October 31, 2018) or the S&amp;amp;P SmallCap 600 Index (approximately $4.4 billion as of October 31, 2018).&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund invests primarily in a diversified mix of common stocks of U.S. small-cap companies. The manager employs a value-oriented investment approach in selecting stocks, using proprietary fundamental research to identify stocks the manager believes have distinct value characteristics based on industry-specific valuation criteria. The manager focuses on high-quality companies with a proven record of above-average rates of profitability that sell at a discount relative to the overall small-cap market.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The manager seeks to identify companies demonstrating one or more of the following characteristics: sustainable competitive advantages within a market niche; strong profitability and free cash flows; strong market share positions and trends; quality of and share ownership by management; and conservative financial structures relative to industry average.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund's sector exposures are broadly diversified but may vary significantly from the fund's benchmark. The fund may invest up to 15% of its total assets in foreign securities (including up to 5% in emerging-market securities). The fund may invest significantly in financial services companies.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal circumstances, the fund invests 10% or less (usually less) of its total assets in cash and cash equivalents.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in initial public offerings (IPOs). The fund may also purchase real estate investment trusts (REITs) or other real estate related equity securities, U.S. dollar-denominated foreign securities, and certain exchange-traded funds (ETFs). ETFs are considered securities with a market capitalization equal to the weighted average market capitalization of the basket of securities that compose the ETF. The fund may focus its investments in a particular sector or sectors of the economy.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Many factors affect performance, and fund shares will fluctuate in price, meaning you could lose money. The fund's investment strategy may not produce the intended results.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;During periods of heightened market volatility or reduced liquidity, governments, their agencies, or other regulatory bodies, both within the United States and abroad, may take steps to intervene. These actions, which could include legislative, regulatory, or economic initiatives, might have unforeseeable consequences and could adversely affect the fund's performance or otherwise constrain the fund's ability to achieve its investment objective.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund's main risks are listed below in alphabetical order. &lt;i&gt;Before investing, be sure to read the additional descriptions of these risks beginning on page 5 of the prospectus.&lt;/i&gt;            
            &lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Financial services sector risk.&lt;/b&gt; Financial services companies can be significantly affected by economic, market, and business developments, borrowing costs, interest-rate fluctuations, competition, and government regulation, among other factors.&lt;/div&gt;

               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Real estate investment trust risk.&lt;/b&gt; REITs, pooled investment vehicles that typically invest in real estate directly or in loans collateralized by real estate, carry risks associated with owning real estate, including the potential for a decline in value due to economic or market conditions.&lt;/div&gt;

               &lt;b&gt;Real estate securities risk.&lt;/b&gt; Securities of companies in the real estate industry carry risks associated with owning real estate, including the potential for a decline in value due to economic or market conditions.&lt;/div&gt;

               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;

               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Value investing style risk.&lt;/b&gt; The fund emphasizes a value style of investing, which focuses on undervalued companies with characteristics for improved valuations. This style of investing is subject to the risk that the valuations never improve or that the returns on value equity securities are less than returns on other styles of investing or the overall stock market. Value stocks also may decline in price, even though in theory they are already underpriced.&lt;/div&gt;

More information about these and other discounts is available from your financial representative and on pages 20 to 22 of the prospectus under "Sales charge reductions and waivers" or pages 273 to 277 of the fund's Statement of Additional Information under "Sales Charges on Class A, Class B, and Class C Shares."&lt;/div&gt;

The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's performance. During its most recent fiscal year, the fund's portfolio turnover rate was 65% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund diversifies its assets widely among various fixed-income and equity market segments. The fund seeks to maintain broad exposure primarily to domestic and international fixed-income markets in an attempt to reduce the impact of declining markets and to benefit from good performance in particular market segments over time.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund normally invests in investment-grade corporate, high-yield, and foreign and emerging-market fixed-income securities, income-oriented stocks, short-term securities, asset-backed and mortgage-related securities, and U.S. government and agency securities. The fund will also seek equity income through investments in dividend-paying stocks.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Fixed-income securities may have short-, intermediate-, or long-term maturities, and will comprise a range of credit qualities with either fixed or floating interest rates. Fixed-income investments in which the fund may invest without limit include investment-grade corporate securities, asset-backed and mortgage-related securities, and bank loan participations and assignments. The fund's fixed-income investments may include privately negotiated notes or loans, including loan participations and assignments (bank loans). Some loans may be illiquid.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in asset-backed securities rated lower than A (but not lower than B by Standard &amp;amp; Poor's Ratings Services, Moody's Investors Service, Inc. or Fitch Ratings Inc.). Under normal circumstances, no more than 15% of the asset-backed securities purchased for the fund will be rated less than A- by the three agencies. The lowest rating would apply in the case of split-rated asset-backed securities. Mortgage-related investments could include mortgage dollar rolls and investments in more volatile stripped mortgage securities and collateralized mortgage obligations. The fund may invest a substantial portion (up to 40% of its total assets) in below-investment-grade fixed-income securities (or their unrated equivalents), commonly known as junk bonds. The fund may invest in U.S. government and municipal securities (including Treasury Inflation-Protected Securities or TIPs), GNMAs, and other agency-related fixed income securities, and there is no limit on the fund's investment in these securities. The fund may also invest up to 45% of its total assets in foreign government and emerging-market fixed-income securities (excluding Yankee bonds). Foreign currency forwards, options, and futures may be used to protect the fund's foreign securities from adverse currency movements relative to the U.S. dollar, as well as to gain exposure to currencies and markets expected to increase or decrease in value relative to other securities. The fund's investment policies are based on credit ratings at the time of purchase.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The manager uses fundamental research and credit analysis to select fixed-income securities. The manager considers a variety of factors in analyzing fixed-income securities, including the issuer's financial condition and operating history, the depth and quality of management, sensitivities to economic conditions, debt levels and ability to service its outstanding debt, access to capital markets, and external factors such as the economic and political conditions in the issuer's country. Other than the specific investment limits described above, there is no minimum or maximum percentage of assets that the manager will invest in any particular type of fixed-income security. Maturities of the fund's fixed-income investments reflect the manager's outlook for interest rates.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The manager selects the fund's equity investments (limited to 40% of total assets ) using a value strategy with a focus on large-cap, dividend-paying common stocks. The manager invests in stocks and other securities, including preferred stock and convertible securities that appear to be temporarily undervalued by various measures and may be temporarily out of favor, but have good prospects for capital appreciation and dividend growth. The manager may vary the allocation of the fund's assets to a particular market segment based on the relative valuations of these market segments.The manager may also weigh such factors as the outlook for the economy and market conditions, both on a global and local (country) basis, corporate earnings, and the yield advantages of one fixed-income sector over another.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund holds a certain portion of its assets in money market reserves consisting of shares of the T. Rowe Price Government Reserve Fund (or any other internal T. Rowe Price money market fund) or U.S. dollar- and foreign currency-denominated money market securities. These include repurchase agreements in the two highest rating categories that mature in one year or less. The fund may invest reserves in U.S. dollars and foreign currencies.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest up to 10% of its total assets in hybrid instruments. Hybrid instruments are a type of high-risk derivative which can combine the characteristics of securities, futures, and options. Such securities may bear interest or pay dividends at below-market rates or even relatively nominal market rates.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;In pursuing the fund's investment objective, the manager may deviate from the fund's normal investment criteria to purchase securities the manager believes might appreciate substantially. The fund may invest significantly in the information technology sector.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund's investment process may, at times, result in a high portfolio turnover rate.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Many factors affect performance, and fund shares will fluctuate in price, meaning you could lose money. The fund's investment strategy may not produce the intended results.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;During periods of heightened market volatility or reduced liquidity, governments, their agencies, or other regulatory bodies, both within the United States and abroad, may take steps to intervene. These actions, which could include legislative, regulatory, or economic initiatives, might have unforeseeable consequences and could adversely affect the fund's performance or otherwise constrain the fund's ability to achieve its investment objective.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund's main risks are listed below in alphabetical order. &lt;i&gt;Before investing, be sure to read the additional descriptions of these risks beginning on page 7 of the prospectus.&lt;/i&gt;            
            &lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Changing distribution levels risk.&lt;/b&gt; The fund may cease or reduce the level of its distribution if income or dividends paid from its investments declines.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: foreign currency forward contracts, futures contracts, and options. Foreign currency forward contracts, futures contracts, and options generally are subject to counterparty risk. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;High portfolio turnover risk.&lt;/b&gt; Trading securities actively and frequently can increase transaction costs (thus lowering performance) and taxable distributions.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hybrid instrument risk.&lt;/b&gt; Hybrid instruments entail greater market risk and may be more volatile than traditional debt instruments, may bear interest or pay preferred dividends at below-market rates, and may be illiquid. The risks of investing in hybrid instruments are a combination of the risks of investing in securities, options, futures, and currencies.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Information technology risk.&lt;/b&gt; Information technology companies can be significantly affected by rapid obsolescence, short product cycles, competition, and government regulation, among other factors. Investments in the technology sector may be susceptible to heightened risk of cybersecurity breaches, which may allow an unauthorized party to gain access to personally identifiable information and other customer data.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Investment company securities risk.&lt;/b&gt; A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Loan participations risk.&lt;/b&gt; Participations and assignments involve special types of risks, including credit risk, interest-rate risk, counterparty risk, liquidity risk, risks associated with extended settlement, and the risks of being a lender.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Municipal bond risk.&lt;/b&gt; The prices of municipal bonds, including general obligation bonds, can decline if the issuer's credit quality declines. Revenue bond prices can decline if related projects become unprofitable. An insured municipal bond is subject to the risk that the insurer may be unable to pay claims and is not insured with respect to the market value of the obligation. Municipal bond income could become taxable in the future. Investments in AMT bonds may result in tax liability for shareholders.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;

The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's performance. During its most recent fiscal year, the fund's portfolio turnover rate was 65% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund normally invests in investment-grade corporate, high-yield, and foreign and emerging-market fixed-income securities, income-oriented stocks, short-term securities, asset-backed and mortgage-related securities, and U.S. government and agency securities. The fund will also seek equity income through investments in dividend-paying stocks.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Fixed-income securities may have short-, intermediate-, or long-term maturities, and will comprise a range of credit qualities with either fixed or floating interest rates. Fixed-income investments in which the fund may invest without limit include investment-grade corporate securities, asset-backed and mortgage-related securities, and bank loan participations and assignments. The fund's fixed-income investments may include privately negotiated notes or loans, including loan participations and assignments (bank loans). Some loans may be illiquid.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in asset-backed securities rated lower than A (but not lower than B by Standard &amp;amp; Poor's Ratings Services, Moody's Investors Service, Inc. or Fitch Ratings Inc.). Under normal circumstances, no more than 15% of the asset-backed securities purchased for the fund will be rated less than A- by the three agencies. The lowest rating would apply in the case of split-rated asset-backed securities. Mortgage-related investments could include mortgage dollar rolls and investments in more volatile stripped mortgage securities and collateralized mortgage obligations. The fund may invest a substantial portion (up to 40% of its total assets) in below-investment-grade fixed-income securities (or their unrated equivalents), commonly known as junk bonds. The fund may invest in U.S. government and municipal securities (including Treasury Inflation-Protected Securities or TIPs), GNMAs, and other agency-related fixed income securities, and there is no limit on the fund's investment in these securities. The fund may also invest up to 45% of its total assets in foreign government and emerging-market fixed-income securities (excluding Yankee bonds). Foreign currency forwards, options, and futures may be used to protect the fund's foreign securities from adverse currency movements relative to the U.S. dollar, as well as to gain exposure to currencies and markets expected to increase or decrease in value relative to other securities. The fund's investment policies are based on credit ratings at the time of purchase.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The manager uses fundamental research and credit analysis to select fixed-income securities. The manager considers a variety of factors in analyzing fixed-income securities, including the issuer's financial condition and operating history, the depth and quality of management, sensitivities to economic conditions, debt levels and ability to service its outstanding debt, access to capital markets, and external factors such as the economic and political conditions in the issuer's country. Other than the specific investment limits described above, there is no minimum or maximum percentage of assets that the manager will invest in any particular type of fixed-income security. Maturities of the fund's fixed-income investments reflect the manager's outlook for interest rates.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The manager selects the fund's equity investments (limited to 40% of total assets ) using a value strategy with a focus on large-cap, dividend-paying common stocks. The manager invests in stocks and other securities, including preferred stock and convertible securities that appear to be temporarily undervalued by various measures and may be temporarily out of favor, but have good prospects for capital appreciation and dividend growth. The manager may vary the allocation of the fund's assets to a particular market segment based on the relative valuations of these market segments.The manager may also weigh such factors as the outlook for the economy and market conditions, both on a global and local (country) basis, corporate earnings, and the yield advantages of one fixed-income sector over another.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund holds a certain portion of its assets in money market reserves consisting of shares of the T. Rowe Price Government Reserve Fund (or any other internal T. Rowe Price money market fund) or U.S. dollar- and foreign currency-denominated money market securities. These include repurchase agreements in the two highest rating categories that mature in one year or less. The fund may invest reserves in U.S. dollars and foreign currencies.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest up to 10% of its total assets in hybrid instruments. Hybrid instruments are a type of high-risk derivative which can combine the characteristics of securities, futures, and options. Such securities may bear interest or pay dividends at below-market rates or even relatively nominal market rates.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;In pursuing the fund's investment objective, the manager may deviate from the fund's normal investment criteria to purchase securities the manager believes might appreciate substantially. The fund may invest significantly in the information technology sector.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund's investment process may, at times, result in a high portfolio turnover rate.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Many factors affect performance, and fund shares will fluctuate in price, meaning you could lose money. The fund's investment strategy may not produce the intended results.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;During periods of heightened market volatility or reduced liquidity, governments, their agencies, or other regulatory bodies, both within the United States and abroad, may take steps to intervene. These actions, which could include legislative, regulatory, or economic initiatives, might have unforeseeable consequences and could adversely affect the fund's performance or otherwise constrain the fund's ability to achieve its investment objective.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund's main risks are listed below in alphabetical order. &lt;i&gt;Before investing, be sure to read the additional descriptions of these risks beginning on page 7 of the prospectus.&lt;/i&gt;            
            &lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Changing distribution levels risk.&lt;/b&gt; The fund may cease or reduce the level of its distribution if income or dividends paid from its investments declines.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: foreign currency forward contracts, futures contracts, and options. Foreign currency forward contracts, futures contracts, and options generally are subject to counterparty risk. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;High portfolio turnover risk.&lt;/b&gt; Trading securities actively and frequently can increase transaction costs (thus lowering performance) and taxable distributions.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hybrid instrument risk.&lt;/b&gt; Hybrid instruments entail greater market risk and may be more volatile than traditional debt instruments, may bear interest or pay preferred dividends at below-market rates, and may be illiquid. The risks of investing in hybrid instruments are a combination of the risks of investing in securities, options, futures, and currencies.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Information technology risk.&lt;/b&gt; Information technology companies can be significantly affected by rapid obsolescence, short product cycles, competition, and government regulation, among other factors. Investments in the technology sector may be susceptible to heightened risk of cybersecurity breaches, which may allow an unauthorized party to gain access to personally identifiable information and other customer data.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Investment company securities risk.&lt;/b&gt; A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Loan participations risk.&lt;/b&gt; Participations and assignments involve special types of risks, including credit risk, interest-rate risk, counterparty risk, liquidity risk, risks associated with extended settlement, and the risks of being a lender.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Municipal bond risk.&lt;/b&gt; The prices of municipal bonds, including general obligation bonds, can decline if the issuer's credit quality declines. Revenue bond prices can decline if related projects become unprofitable. An insured municipal bond is subject to the risk that the insurer may be unable to pay claims and is not insured with respect to the market value of the obligation. Municipal bond income could become taxable in the future. Investments in AMT bonds may result in tax liability for shareholders.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's performance. During its most recent fiscal year, the fund's portfolio turnover rate was 63% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests at least 80% of its assets in the following types of securities, which may be denominated in U.S. dollars or foreign currencies: foreign government and corporate debt securities from developed and emerging markets, U.S. government and agency securities, domestic high-yield bonds, and investment-grade corporate bonds and currency instruments. The fund may also invest in preferred stock and other types of debt securities, including mortgage-and asset-backed securities and loans. Some loans may be illiquid. No more than 80% of the fund's assets will consist of instruments denominated in foreign currencies.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Although the fund may invest up to 10% of its total assets in securities rated as low as D (in default) by Standard &amp;amp; Poor's Ratings Services (S&amp;amp;P) or Moody's Investors Service, Inc. (Moody's), or their unrated equivalents, it generally intends to keep its average credit quality in the investment-grade range (i.e., AAA to BBB). Bonds that are rated at or below BB by S&amp;amp;P or Ba by Moody's are considered junk bonds. There is no limit on the average maturity of the fund's portfolio. The fund's investment policies are based on credit ratings at the time of purchase. Under normal circumstances, the fund may invest up to 15% of total assets in asset-backed securities rated lower than A by S&amp;amp;P or Moody's, or their unrated equivalents (but under no circumstances lower than B or their unrated equivalents).&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;In managing the fund, the manager allocates assets among the four major types of instruments noted above based on analysis of global economic factors such as fiscal and monetary policies, projected international interest-rate movements, political environments, and currency trends. In abnormal circumstances, the manager may invest up to 100% of the fund's assets in any one sector. The manager looks for investments that are appropriate for the fund in terms of yield, credit quality, structure, and industry distribution. Relative yields and risk/reward ratios are the primary considerations in selecting securities.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may use certain higher-risk investments, including derivatives such as futures, options, and swaps (including credit default swaps), as well as restricted or illiquid securities. The fund may also invest significantly in currency spots and forwards, currency futures and options, and interest-rate options for both hedging and nonhedging purposes, including for purposes of enhancing returns. In addition, the fund may invest up to 10% of its net assets in domestic or foreign common stocks.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Many factors affect performance, and fund shares will fluctuate in price, meaning you could lose money. The fund's investment strategy may not produce the intended results.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;During periods of heightened market volatility or reduced liquidity, governments, their agencies, or other regulatory bodies, both within the United States and abroad, may take steps to intervene. These actions, which could include legislative, regulatory, or economic initiatives, might have unforeseeable consequences and could adversely affect the fund's performance or otherwise constrain the fund's ability to achieve its investment objective.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund's main risks are listed below in alphabetical order. &lt;i&gt;Before investing, be sure to read the additional descriptions of these risks beginning on page 6 of the prospectus.&lt;/i&gt;            
            &lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Asset-backed securities risk.&lt;/b&gt; Asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Changing distribution levels risk.&lt;/b&gt; The fund may cease or reduce the level of its distribution if income or dividends paid from its investments declines.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Currency risk.&lt;/b&gt; Fluctuations in exchange rates may adversely affect the U.S. dollar value of a fund's investments. Foreign currencies may decline in value, which could negatively impact performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Defaulted debt risk.&lt;/b&gt; Investing in defaulted debt securities is speculative and involves substantial risks in addition to those of non-defaulted high-yield securities. Defaulted debt securities generally do not generate interest payments. Principal on defaulted debt might not be repaid, and a fund could lose up to its entire investment.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, options, and swaps. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;High portfolio turnover risk.&lt;/b&gt; Trading securities actively and frequently can increase transaction costs (thus lowering performance) and taxable distributions.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The following information illustrates the variability of the fund's returns and provides some indication of the risks of investing in the fund by showing changes in the fund's performance from year to year and by showing how the fund's average annual returns compared with a broad-based market index. Past performance (before and after taxes) does not indicate future results. All figures assume dividend reinvestment. Performance for the fund is updated daily, monthly, and quarterly and may be obtained at our website, jhinvestments.com, or by calling 800-225-5291 (Class A and Class C shares), Monday to Thursday, 8:00 A.M.&#8212;7:00 P.M., and Friday, 8:00 A.M.&#8212;6:00 P.M., Eastern time, or 888-972-8696 (Class I, Class R2, and Class R6 shares) between 8:30 A.M. and 5:00 P.M., Eastern time, on most business days.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Class NAV, Class R6, and Class R2 shares commenced operations on April 28, 2006, September 1, 2011, and March 1, 2012, respectively.  Class A, Class C, and Class I shares commenced operations on January 4, 2010. Returns shown prior to a class's commencement date are those of Class NAV shares, except that they include any sales charges. Returns for Class A, Class C, Class I, Class R2, and Class R6 shares would have been substantially similar to returns of Class NAV shares because each share class is invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Please note that after-tax returns (shown for Class A shares only) reflect the highest individual federal marginal income-tax rate in effect as of the date provided and do not reflect any state or local taxes. Your actual after-tax returns may be different. After-tax returns are not relevant to shares held in an IRA, 401(k), or other tax-advantaged investment plan. After-tax returns for other share classes would vary. The returns for Class A shares have been adjusted to reflect the reduction in the maximum sales charge from 4.50% to 4.00%, effective February 3, 2014.&lt;/div&gt;

Intermediaries may have different policies and procedures regarding the availability of front-end sales charge waivers or CDSC waivers (See Appendix 1 - Intermediary sales charge waivers

               ). More information about these and other discounts is available from your financial representative and on pages 17 to 19 of this prospectus under "Sales charge reductions and waivers" or pages 273 to 277 of the fund's Statement of Additional Information under "Sales Charges on Class A, Class B, and Class C Shares."&lt;/div&gt;

Please see below a hypothetical example showing the expenses of a $10,000 investment for the time periods indicated and then, except as shown below, assuming you sell all of your shares at the end of those periods. The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's performance. During its most recent fiscal year, the fund's portfolio turnover rate was 74% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in equity investments that are tied economically to the United States. The fund considers an equity investment to be "tied economically" to the United States if, at the time of purchase: (i) its issuer is organized under the laws of the United States or under the laws of a state within the United States or in an issuer that maintains its principal place of business in the United States; (ii) it is traded principally in the United States; or (iii) its issuer derived at least 50% of its revenues or profits from goods produced or sold, investments made, or services performed in the United States, or has at least 50% of its assets in the United States. The manager seeks to achieve the fund's investment objective by investing in equity investments that the manager believes, as a portfolio, will provide higher returns than the Russell 1000 Growth Index.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The manager's investment process begins with the broad universe of equity securities included in US equity indices, along with other ideas that come from a combination of company meetings, investment conferences, field trips and industry analysis. Investments in equity securities include common stocks and other stock-related securities such as preferred stocks, convertible securities, depositary receipts, exchange-traded funds, and exchange-traded equity real estate investment trusts (REITs). The fund may invest significantly in securities of companies in certain sectors, and may therefore experience greater volatility than funds investing in a broader range of sectors and may be more susceptible to the impact of market, economic, regulatory, and other factors affecting that sector.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The manager focuses on members of the investable universe with expected future free cash-flow margins, returns on capital employed and revenue growth higher than a certain minimum threshold. The manager then monitors and ranks securities based on their relative attractiveness across this universe, based on quality, growth, valuation, capital returns, and earnings outlook. For stocks that compare well in this screening process, further detailed analysis is conducted. Regular meetings and discussions with company management are another input into the portfolio decision making process.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Securities considered for purchase are attractive on a majority of the metrics (quality, growth, valuation, capital returns, and earnings outlook), and have a positive catalyst such as accelerating earnings or revenue growth. Due to its active investment strategy, the fund may buy and sell securities frequently. This may result in higher transaction costs and more capital gains tax liabilities than a fund with a buy and hold strategy.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Many factors affect performance, and fund shares will fluctuate in price, meaning you could lose money. The fund's investment strategy may not produce the intended results.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;During periods of heightened market volatility or reduced liquidity, governments, their agencies, or other regulatory bodies, both within the United States and abroad, may take steps to intervene. These actions, which could include legislative, regulatory, or economic initiatives, might have unforeseeable consequences and could adversely affect the fund's performance or otherwise constrain the fund's ability to achieve its investment objective.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund's main risks are listed below in alphabetical order. &lt;i&gt;Before investing, be sure to read the additional descriptions of these risks beginning on page 5 of the prospectus.&lt;/i&gt;            
            &lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;

               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;

               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;

               &lt;b&gt;High portfolio turnover risk.&lt;/b&gt; Trading securities actively and frequently can increase transaction costs (thus lowering performance) and taxable distributions.&lt;/div&gt;

               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;

               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments.&lt;/div&gt;

               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Real estate investment trust risk.&lt;/b&gt; REITs, pooled investment vehicles that typically invest in real estate directly or in loans collateralized by real estate, carry risks associated with owning real estate, including the potential for a decline in value due to economic or market conditions.&lt;/div&gt;

               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;

               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

Class A and Class I shares commenced operations on October 31, 2011. Class R6 shares commenced operations on November 8, 2016. Returns shown prior to a class's commencement date are those of Class NAV shares, except that they include any sales charges. Returns for Class A, Class C, Class I and Class R6 shares would have been substantially similar to returns of Class NAV shares because each share class is invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.&lt;/div&gt;

As a result of the difference in investment strategy and subadvisor, the fund's performance shown below might have differed materially.&lt;/div&gt;

Your actual after-tax returns may be different. After-tax returns are not relevant to shares held in an IRA, 401(k), or other tax-advantaged investment plan.

Through these alternative yield positions, the fund seeks long-term capital appreciation with a high degree of downside protection and reduced volatility relative to the broad U.S. equity market.&lt;/div&gt;

Please see below a hypothetical example showing the expenses of a $10,000 investment for the time periods indicated and then assuming you sell all of your shares at the end of those periods. The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's performance. During its most recent fiscal year, the fund's portfolio turnover rate was 73% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund seeks to achieve its investment objective, under normal circumstances, by primarily investing in U.S. equities and simultaneously selling a call option against those stocks. The call options will typically have a strike price lower than the current stock price, which is termed "in the money." This combination of long stock position and short in the money call option creates a yield instrument. Additionally, the fund can engage in writing out-of-the-money put options on U.S. equities. Writing out-of-the-money put options is analogous to buying the stock and selling the call option with the same strike price and generally achieves the same result. These two strategies are equivalent in terms of risk/reward due to put-call parity. In making investment decisions, the manager ordinarily analyzes estimates of "intrinsic value" (i.e., the potential downside volatility level) and correlation between such estimates and time to expiration, as well as potential returns relative to risk.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The strike price of the call options is usually set at or below the estimated intrinsic value level of the securities against which they are sold and the time to expiration of the options that the fund sells varies. The fund may also write (sell) in-the-money call options on equity indexes and/or exchange-traded funds and write call options on individual securities that it does not hold in its portfolio (i.e., naked call options).&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The issuers of equity securities purchased by the fund will primarily have market capitalizations in excess of $2 billion. The fund may invest in companies located both within and outside the United States (including in emerging markets). The fund may invest any percentage of assets in any one country, region or geographic area. The fund may invest in initial public offerings (IPOs) and in exchange-traded funds (ETFs). In addition to common stocks and other equity securities (such as preferred stocks, convertible securities, and warrants), the fund may use foreign currency forward contracts, options, stock index futures contracts, and other derivative instruments, primarily for the purpose of reducing the risks of individual equity positions and maximizing risk-adjusted returns, and may also be used to hedge broad market exposure. In addition to the use of written option contracts, the fund may use foreign currency forward contracts, other options, stock index futures contracts, other futures and forward contracts, swap agreements, variance swaps, convertibles and reverse convertibles, and other derivative instruments for hedging purposes or to enhance return. Variance swap agreements involve an agreement by the two parties to exchange cash flows based on the measured variance (or square of volatility) of a specified underlying asset.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund's investment process may result in an extremely high portfolio turnover ratio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations.&lt;/div&gt;

               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;

               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: foreign currency forward contracts, futures contracts, variance swaps, options, and swaps. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk. With naked short call positions, the writer of the option may have unlimited liability as the writer may be forced to purchase the stock for delivery at a significantly higher price than the strike price of the option.&lt;/div&gt;

               &lt;b&gt;High portfolio turnover risk.&lt;/b&gt; Trading securities actively and frequently can increase transaction costs (thus lowering performance) and taxable distributions.&lt;/div&gt;

               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;

               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;

               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments.&lt;/div&gt;

               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;

               &lt;b&gt;Warrants risk.&lt;/b&gt; The prices of warrants may not precisely reflect the prices of their underlying securities. Warrant holders do not receive dividends or have voting or credit rights. A warrant ceases to have value if not exercised prior to its expiration date.&lt;/div&gt;

The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's performance. During its most recent fiscal year, the fund's portfolio turnover rate was 74% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in equity investments that are tied economically to the United States. The fund considers an equity investment to be "tied economically" to the United States if, at the time of purchase: (i) its issuer is organized under the laws of the United States or under the laws of a state within the United States or in an issuer that maintains its principal place of business in the United States; (ii) it is traded principally in the United States; or (iii) its issuer derived at least 50% of its revenues or profits from goods produced or sold, investments made, or services performed in the United States, or has at least 50% of its assets in the United States. The manager seeks to achieve the fund's investment objective by investing in equity investments that the manager believes, as a portfolio, will provide higher returns than the Russell 1000 Growth Index.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The manager's investment process begins with the broad universe of equity securities included in US equity indices, along with other ideas that come from a combination of company meetings, investment conferences, field trips and industry analysis. Investments in equity securities include common stocks and other stock-related securities such as preferred stocks, convertible securities, depositary receipts, exchange-traded funds, and exchange-traded equity real estate investment trusts (REITs). The fund may invest significantly in securities of companies in certain sectors, and may therefore experience greater volatility than funds investing in a broader range of sectors and may be more susceptible to the impact of market, economic, regulatory, and other factors affecting that sector.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The manager focuses on members of the investable universe with expected future free cash-flow margins, returns on capital employed and revenue growth higher than a certain minimum threshold. The manager then monitors and ranks securities based on their relative attractiveness across this universe, based on quality, growth, valuation, capital returns, and earnings outlook. For stocks that compare well in this screening process, further detailed analysis is conducted. Regular meetings and discussions with company management are another input into the portfolio decision making process.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Securities considered for purchase are attractive on a majority of the metrics (quality, growth, valuation, capital returns, and earnings outlook), and have a positive catalyst such as accelerating earnings or revenue growth. Due to its active investment strategy, the fund may buy and sell securities frequently. This may result in higher transaction costs and more capital gains tax liabilities than a fund with a buy and hold strategy.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is subject to risks, and you could lose money by investing in the fund. The principal risks of investing in the fund include:&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;

               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;

               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;

               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;High portfolio turnover risk.&lt;/b&gt; Trading securities actively and frequently can increase transaction costs (thus lowering performance) and taxable distributions.&lt;/div&gt;

Past performance (before and after taxes) does not indicate future results. All figures assume dividend reinvestment. Performance information is updated daily, monthly, and quarterly, and may be obtained at our website, jhinvestments.com, or by calling 800-344-1029 between 8:00 A.M. and 7:00 P.M., Eastern time, on most business days.&lt;/div&gt;

The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's performance. During its most recent fiscal year, the fund's portfolio turnover rate was 43% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund seeks to generate capital appreciation by investing at least 80% of net assets (plus borrowings for investment purposes) in a diversified portfolio of equity securities. Under normal market conditions, at least 40% of the value of the fund's net assets will be invested in securities of issuers domiciled outside of the United States, including in emerging markets. This includes securities of foreign issuers that trade on U.S. exchanges. Equity securities include common and preferred stocks and their equivalents, including depositary receipts, warrants, rights, and convertible securities. The fund may invest in securities of any market-capitalization.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The manager employs an unconstrained, bottom-up stock selection process based on fundamental research to attempt to identify undervalued companies that exhibit attractive valuations, solid business franchises, sustainable margins/cash flow, disciplined capital allocation, strong management teams, and strong balance sheets. The manager considers diversification benefits and liquidity of the security in making investment decisions.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is subject to risks, and you could lose money by investing in the fund. The principal risks of investing in the fund include:&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Emerging-market risk.&lt;/b&gt; The risks of investing in foreign securities are magnified in emerging markets. Emerging-market countries may experience higher inflation, interest rates, and unemployment and greater social, economic, and political uncertainties than more developed countries.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Warrants risk.&lt;/b&gt; The prices of warrants may not precisely reflect the prices of their underlying securities. Warrant holders do not receive dividends or have voting or credit rights. A warrant ceases to have value if not exercised prior to its expiration date.&lt;/div&gt;

Please see below a hypothetical example showing the expenses of a $10,000 investment for the time periods indicated and then assuming you sell all of your shares at the end of those periods. The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's performance. During its most recent fiscal year, the fund's portfolio turnover rate was 65% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund diversifies its assets widely among various fixed-income and equity market segments. The fund seeks to maintain broad exposure primarily to domestic and international fixed-income markets in an attempt to reduce the impact of declining markets and to benefit from good performance in particular market segments over time.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund normally invests in investment-grade corporate, high-yield, and foreign and emerging-market fixed-income securities, income-oriented stocks, short-term securities, asset-backed and mortgage-related securities, and U.S. government and agency securities. The fund will also seek equity income through investments in dividend-paying stocks.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Fixed-income securities may have short-, intermediate-, or long-term maturities, and will comprise a range of credit qualities with either fixed or floating interest rates. Fixed-income investments in which the fund may invest without limit include investment-grade corporate securities, asset-backed and mortgage-related securities, and bank loan participations and assignments. The fund's fixed-income investments may include privately negotiated notes or loans, including loan participations and assignments (bank loans). Some loans may be illiquid.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in asset-backed securities rated lower than A (but not lower than B by Standard &amp;amp; Poor's Ratings Services, Moody's Investors Service, Inc. or Fitch Ratings Inc.). Under normal circumstances, no more than 15% of the asset-backed securities purchased for the fund will be rated less than A- by the three agencies. The lowest rating would apply in the case of split-rated asset-backed securities. Mortgage-related investments could include mortgage dollar rolls and investments in more volatile stripped mortgage securities and collateralized mortgage obligations. The fund may invest a substantial portion (up to 40% of its total assets) in below-investment-grade fixed-income securities (or their unrated equivalents), commonly known as junk bonds. The fund may invest in U.S. government and municipal securities (including Treasury Inflation-Protected Securities or TIPs), GNMAs, and other agency-related fixed income securities, and there is no limit on the fund's investment in these securities. The fund may also invest up to 45% of its total assets in foreign government and emerging-market fixed-income securities (excluding Yankee bonds). Foreign currency forwards, options, and futures may be used to protect the fund's foreign securities from adverse currency movements relative to the U.S. dollar, as well as to gain exposure to currencies and markets expected to increase or decrease in value relative to other securities. The fund's investment policies are based on credit ratings at the time of purchase.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The manager uses fundamental research and credit analysis to select fixed-income securities. The manager considers a variety of factors in analyzing fixed-income securities, including the issuer's financial condition and operating history, the depth and quality of management, sensitivities to economic conditions, debt levels and ability to service its outstanding debt, access to capital markets, and external factors such as the economic and political conditions in the issuer's country. Other than the specific investment limits described above, there is no minimum or maximum percentage of assets that the manager will invest in any particular type of fixed-income security. Maturities of the fund's fixed-income investments reflect the manager's outlook for interest rates.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The manager selects the fund's equity investments (limited to 40% of total assets ) using a value strategy with a focus on large-cap, dividend-paying common stocks. The manager invests in stocks and other securities, including preferred stock and convertible securities that appear to be temporarily undervalued by various measures and may be temporarily out of favor, but have good prospects for capital appreciation and dividend growth. The manager may vary the allocation of the fund's assets to a particular market segment based on the relative valuations of these market segments.The manager may also weigh such factors as the outlook for the economy and market conditions, both on a global and local (country) basis, corporate earnings, and the yield advantages of one fixed-income sector over another.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund holds a certain portion of its assets in money market reserves consisting of shares of the T. Rowe Price Government Reserve Fund (or any other internal T. Rowe Price money market fund) or U.S. dollar- and foreign currency-denominated money market securities. These include repurchase agreements in the two highest rating categories that mature in one year or less. The fund may invest reserves in U.S. dollars and foreign currencies.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest up to 10% of its total assets in hybrid instruments. Hybrid instruments are a type of high-risk derivative which can combine the characteristics of securities, futures, and options. Such securities may bear interest or pay dividends at below-market rates or even relatively nominal market rates.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;In pursuing the fund's investment objective, the manager may deviate from the fund's normal investment criteria to purchase securities the manager believes might appreciate substantially. The fund may invest significantly in the information technology sector.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund's investment process may, at times, result in a high portfolio turnover rate.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is subject to risks, and you could lose money by investing in the fund. The principal risks of investing in the fund include:&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Changing distribution levels risk.&lt;/b&gt; The fund may cease or reduce the level of its distribution if income or dividends paid from its investments declines.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: foreign currency forward contracts, futures contracts, and options. Foreign currency forward contracts, futures contracts, and options generally are subject to counterparty risk. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;High portfolio turnover risk.&lt;/b&gt; Trading securities actively and frequently can increase transaction costs (thus lowering performance) and taxable distributions.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hybrid instrument risk.&lt;/b&gt; Hybrid instruments entail greater market risk and may be more volatile than traditional debt instruments, may bear interest or pay preferred dividends at below-market rates, and may be illiquid. The risks of investing in hybrid instruments are a combination of the risks of investing in securities, options, futures, and currencies.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Information technology risk.&lt;/b&gt; Information technology companies can be significantly affected by rapid obsolescence, short product cycles, competition, and government regulation, among other factors. Investments in the technology sector may be susceptible to heightened risk of cybersecurity breaches, which may allow an unauthorized party to gain access to personally identifiable information and other customer data.&lt;/div&gt;

               &lt;b&gt;Investment company securities risk.&lt;/b&gt; A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Loan participations risk.&lt;/b&gt; Participations and assignments involve special types of risks, including credit risk, interest-rate risk, counterparty risk, liquidity risk, risks associated with extended settlement, and the risks of being a lender.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Municipal bond risk.&lt;/b&gt; The prices of municipal bonds, including general obligation bonds, can decline if the issuer's credit quality declines. Revenue bond prices can decline if related projects become unprofitable. An insured municipal bond is subject to the risk that the insurer may be unable to pay claims and is not insured with respect to the market value of the obligation. Municipal bond income could become taxable in the future. Investments in AMT bonds may result in tax liability for shareholders.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's performance. During its most recent fiscal year, the fund's portfolio turnover rate was 40% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund will invest at least 80% of its net assets (plus any borrowings for investment purposes) in securities of franchise companies. A franchise company is one whose return on invested capital over a three-year period is above its cost of capital. Return on invested capital quantifies how well a company generates cash flow relative to the capital it has invested in its business, while its cost of capital refers to the cost of raising money to fund its business. These companies will have a leading share of industry sales, the ability to generate consistent sales growth over time as their products and services attract a larger customer base, and a strong record of return on capital invested in the company with a sustainable competitive advantage, meaning bargaining power with buyers and/or sellers and a unique product or process that is difficult to replicate or substitute and hard for others to compete with.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, at least 40% of the value of the fund's net assets will be invested in issuers domiciled outside of the United States, which includes securities for which the relevant reference entity is domiciled outside the United States, such as American Depositary Receipts (ADRs) that trade on U.S. exchanges.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The manager's primary method of analysis is fundamental analysis, which is the ability to assess the health of a company, its competitive positioning, its strength of management, and its competitive advantages. Investment decisions are a function of finding stocks that possess the qualitative factors as outlined above and the manager believes are trading at a significant discount to the manager's estimation of value.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is a non-diversified fund, which means that it may invest in a smaller number of issuers than a diversified fund and may invest more of its assets in the securities of a single issuer.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest significantly in securities of companies in certain sectors, such as the consumer staples and consumer discretionary sectors (as defined by the Global Industry Classification Standards (GICS)), and may therefore experience greater volatility than funds investing in a broader range of sectors and may be more susceptible to the impact of market, economic, regulatory, and other factors affecting that sector.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The manager focuses on the equity securities of small-, mid-, and large-capitalization companies in both developed and emerging countries. The manager primarily invests in common stocks of developed and emerging companies, as well as ADRs, which trade on U.S. exchanges.&lt;/div&gt;

               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's performance. During its most recent fiscal year, the fund's portfolio turnover rate was 19% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in securities of small-cap companies in the particular markets in which the fund invests. Based on market capitalization data as of October 31, 2018, the maximum market capitalization range of companies eligible for purchase by the fund was approximately $1.7 billion to $6.2 billion, depending on the country. The fund will primarily invest in a broad and diverse group of equity securities of foreign small companies in developed markets, but may also hold equity securities of companies located in emerging markets.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund invests its assets in securities listed on bona fide securities exchanges or traded on the over-the-counter markets, including dual-listed securities, either within or outside the issuer's domicile country.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The manager measures company size on a country- or region-specific basis and based primarily on market capitalization. In the countries or regions authorized for investment, the manager first ranks eligible companies based on market capitalizations and then determines the universe of eligible stocks by defining the maximum market capitalization of a small company that may be purchased by the fund with respect to each country or region. These thresholds will vary based on market conditions. The fund intends to use a market-capitalization-weighted approach in seeking to set country weights based on the relative market capitalizations of eligible small companies within each country (see below). Weightings of certain countries may vary from their weightings in international indices.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may also use derivatives such as futures contracts and options on futures contracts to adjust market exposure based on expected cash inflows to or outflows from the fund. Futures contracts and options on futures contracts may be for foreign or U.S. equity securities and indexes. The fund may also enter into forward currency contracts to facilitate settlement of equity purchases of foreign securities, repatriation of foreign currency balances, or currency exchange. In addition to cash, money market instruments, and other short-term investments, the fund may invest in affiliated and unaffiliated unregistered money market funds to manage cash pending investment, to maintain liquidity to pay redemptions, to make other anticipated cash payments, or for other purposes. Investments in money market funds may involve a duplication of certain fees and expenses.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund does not seek current income as an investment objective and investments will not be based on an issuer's dividend payment policy or record, although many of the companies in which the fund invests do pay dividends.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The manager may, in its discretion, invest in countries authorized by its Investment Committee, depending upon factors such as asset growth in the fund and market characteristics. Other countries may be authorized for investment in the future, and the fund may continue to hold investments in countries previously but not currently authorized. The fund may focus its investments in a particular sector or sectors of the economy.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Market-capitalization-weighted approach&lt;/b&gt;            
            &lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund uses market capitalization weighting to determine individual security weights and, where applicable, country or region weights. Market-capitalization weighting means each security is generally purchased based on the issuer's relative market capitalization. Market-capitalization weighting will be adjusted by the manager for a variety of factors, including free float, momentum, trading strategies, liquidity management, profitability, and market conditions, among others. The manager may deviate from market-capitalization weighting to limit or fix the exposure of the fund to a particular country or issuer to a maximum proportion of fund assets and may exclude the stock of a company that meets applicable market-capitalization criteria at its discretion. These adjustments will result in a deviation from traditional market-capitalization weighting.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Country weights may be based on the total market capitalization of companies within each country and may take into consideration the free float of companies within a country or whether these companies are eligible to be purchased for the particular strategy. In addition, to maintain a satisfactory level of diversification, the Investment Committee may limit or adjust the exposure to a particular country or region to a maximum proportion of the assets of that vehicle. Country weights may also vary due to general day-to-day trading patterns and price movements.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is subject to risks, and you could lose money by investing in the fund. The principal risks of investing in the fund include:&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: foreign currency forward contracts, futures contracts, options on futures contracts, and options. Foreign currency forward contracts, futures contracts, and options generally are subject to counterparty risk. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Investment company securities risk.&lt;/b&gt; A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's performance. During its most recent fiscal year, the fund's portfolio turnover rate was 23% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests at least 80% of its net assets in fixed-income securities and debt instruments of emerging-market issuers. The manager may consider, but is not limited to, the classifications by the World Bank, the International Finance Corporation, or the United Nations and its agencies in determining whether a country is an emerging or a developed country. Examples of emerging-market countries include most African, Central Asian, Eastern European, and South and Central American nations.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The manager uses proprietary research to identify specific countries, corporate sectors, and issuers that are attractively priced. The manager's investment decisions are not constrained by market capitalization, company fundamentals, security valuation or seasoning, or similar characteristics. The manager uses economic and industry analysis to try to anticipate shifts in the business cycle. Due to potentially volatile conditions in emerging markets, the fund's portfolio turnover ratio may be higher-than-average, which could increase transaction costs.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in debt securities of any maturity denominated in any currency, including but not limited to: debt issued by governments or government agencies, including the U.S. Treasury; U.S. and foreign corporate-debt instruments; mortgage- and asset-backed securities and collateralized mortgage obligations; and variable and floating-rate senior and subordinated corporate-debt obligations. The fund may invest in countries that do not have sovereign bond ratings or whose bonds are rated below-investment-grade (junk bonds). The fund may invest in corporate or other privately issued debt instruments of issuers with market capitalizations below $1 billion. The fund may attempt to mitigate the risk of unexpected, adverse currency fluctuations through the use of exchange-listed or over-the-counter financial derivatives instruments, including currency forwards, nondeliverable forwards, currency options, interest-rate swaps, interest-rate futures, interest-rate options, index options, and credit default swaps.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is non-diversified and may both invest in a smaller number of issuers and invest more of its assets in the securities of a single issuer than a diversified fund.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is subject to risks, and you could lose money by investing in the fund. The principal risks of investing in the fund include:&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Changing distribution levels risk.&lt;/b&gt; The fund may cease or reduce the level of its distribution if income or dividends paid from its investments declines.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Emerging-market risk.&lt;/b&gt; The risks of investing in foreign securities are magnified in emerging markets. Emerging-market countries may experience higher inflation, interest rates, and unemployment and greater social, economic, and political uncertainties than more developed countries.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts and swaps, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;High portfolio turnover risk.&lt;/b&gt; Trading securities actively and frequently can increase transaction costs (thus lowering performance) and taxable distributions.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;

               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;

Past performance (before and after taxes) does not indicate future results. All figures assume dividend reinvestment. Performance information is updated daily, monthly, and quarterly and may be obtained at our website, jhinvestments.com, or by calling 800-344-1029 between 8:00 A.M. and 7:00 P.M., Eastern time, on most business days.&lt;/div&gt;

Returns for Class NAV shares prior to June 20, 2013 are those of Class A shares except that they do not include sales charges and would be lower if they did. Returns for Class NAV shares would have been substantially similar to returns of Class A shares because each share class is invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.&lt;/div&gt;

Your actual after-tax returns may be different. After-tax returns are not relevant to shares held in an IRA, 401(k), or other tax-advantaged investment plan.&lt;/div&gt;

A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's performance. During its most recent fiscal year, the fund's portfolio turnover rate was 11% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal circumstances, the fund will invest at least 80% of its net assets (plus any borrowings for investment purposes) in companies associated with emerging markets designated from time to time by the Investment Committee of the manager. These emerging markets (Approved Markets) may include frontier markets (early-development emerging markets). A company is associated with an emerging market if its securities meet the definition of "Approved Market Securities," as defined below.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund invests across all market capitalizations with an increased exposure to securities of small-cap issuers and securities the manager considers to be value securities, as described below. The fund invests primarily in Approved Markets equity securities listed on bona fide securities exchanges of any country or actively traded on over-the-counter markets. The fund may invest in financial services companies. The fund also may invest up to 10% of its total assets in shares of other investment companies that invest in one or more Approved Markets, although it intends to do so only where access to those markets is otherwise significantly limited.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The manager primarily considers value stocks to be those with a low price in relation to their book value. The manager may also consider additional factors such as price-to-cash flow or price-to-earnings ratios, as well as economic conditions and developments in the issuer's industry. The criteria used to assess value may change from time to time. The manager may also consider profitability of an eligible company relative to others in making investment decisions. In assessing profitability, the manager may consider ratios such as earnings or profits from operations relative to book value or assets.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;In determining Approved Markets, the manager may consider various factors, including, without limitation, the data, analysis, and classification of countries published or disseminated by the World Bank, the International Finance Corporation, FTSE International, MSCI, and Citigroup. Approved Markets may not include all emerging markets classified by such entities. Other factors the manager may consider include market liquidity, information availability, government regulations (including repatriation rules), and market access, among others.&lt;/div&gt;

               The fund may also use derivatives such as futures contracts and options on futures contracts to adjust market exposure based on expected cash inflows to or outflows from the fund. The fund may use derivatives for an Approved Market or other equity market (including U.S.) securities and indexes. The fund may also enter into forward currency contracts to facilitate the settlement of equity purchases of foreign securities, repatriation of foreign currency balances, or currency exchange.            
            &lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;To facilitate seeking broad market diversification, the manager will not use fundamental securities research techniques in selecting securities. The manager retains full discretion with respect to investing in and allocating assets among Approved Markets and issuers associated with them. The fund may focus its investments in a particular sector or sectors of the economy.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;As of the date of this prospectus, the fund considers the following emerging-market countries to be Approved Markets for purposes of its 80% policy described above. In determining when and whether to invest in an Approved Market, the manager may consider factors such as asset growth in the fund and market characteristics. The Investment Committee of the manager may authorize countries for future investment in addition to the countries listed below. The fund may continue to hold investments in countries previously authorized for investment that are not currently authorized.&lt;/div&gt;

               "Approved Market Securities" are defined as securities that are associated with an Approved Market, and include, among others: (a) securities of companies that are organized under the laws of, or maintain their principal place of business in, an Approved Market; (b) securities for which the principal trading market is in an Approved Market; (c) securities issued or guaranteed by the government of an Approved Market country, its agencies or instrumentalities, or the central bank of such country; (d) securities denominated in an Approved Market currency issued by companies to finance operations in Approved Markets; (e) securities of companies that derive at least 50% of their revenues or profits from goods produced or sold, investments made, or services performed in Approved Markets, or have at least 50% of their assets in Approved Markets; (f) Approved Market equity securities in the form of depositary shares; (g) securities of pooled investment vehicles that invest primarily in Approved Markets securities or derivative instruments that derive their value from Approved Market securities; or (h) securities included in the fund's benchmark index. Securities of Approved Markets may include securities of companies that have characteristics and business relationships common to companies in other countries. As a result, the value of the securities of such companies may reflect economic and market forces in such other countries as well as in the Approved Markets. The manager, however, will select only those companies that, in its view, have sufficiently strong exposure to economic and market forces in Approved Markets. For example, the manager may invest in companies organized and located in the United States or other countries outside of Approved Markets, including companies having their entire production facilities outside of Approved Markets, when such companies' securities meet the definition of Approved Market securities.            
            &lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is subject to risks, and you could lose money by investing in the fund. The principal risks of investing in the fund include:&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Currency risk.&lt;/b&gt; Fluctuations in exchange rates may adversely affect the U.S. dollar value of a fund's investments. Foreign currencies may decline in value, which could negatively impact performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Emerging-market risk.&lt;/b&gt; The risks of investing in foreign securities are magnified in emerging markets. Emerging-market countries may experience higher inflation, interest rates, and unemployment and greater social, economic, and political uncertainties than more developed countries.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Frontier-market risk.&lt;/b&gt; Frontier-market countries generally have smaller economies and less-developed capital markets and political systems than traditional emerging-market countries, which magnifies emerging-market risks.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Financial services sector risk.&lt;/b&gt; Financial services companies can be significantly affected by economic, market, and business developments, borrowing costs, interest-rate fluctuations, competition, and government regulation, among other factors.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Greater China risk.&lt;/b&gt; Investments in the Greater China region may be subject to less developed trading markets, acute political risks such as possible negative repercussions resulting from China's relationship with Taiwan or Hong Kong, and restrictions on monetary repatriation or other adverse government actions. For example, a government may restrict investment in companies or industries considered important to national interests, or intervene in the financial markets, such as by imposing trading restrictions, or banning or curtailing short selling. A small number of companies and industries represent a relatively large portion of the Greater China market.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: foreign currency forward contracts, futures contracts, options on futures contracts, and options. Foreign currency forward contracts, futures contracts, and options generally are subject to counterparty risk. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Investment company securities risk.&lt;/b&gt; A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;

A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's performance. During its most recent fiscal year, the fund's portfolio turnover rate was 71% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund will invest at least 80% of its net assets (plus any borrowings for investment purposes) in floating-rate loans, which often include debt securities of domestic and foreign issuers that are rated below investment grade (rated below Baa by a nationally recognized statistical rating organization such as Moody's Investors Service, Inc. or BBB by Standard and Poor's Ratings Services), at the time of purchase, or are of comparable quality, as determined by the manager, and other floating-rate securities. Bonds that are rated at or below BB by Standard and Poor's Ratings Services or Ba by Moody's Investors Service, Inc. are considered junk bonds.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in domestic and foreign loans and loan participations that pay interest at rates that float or reset periodically at a margin above a generally recognized base lending rate such as the Prime Rate, the London InterBank Offered Rate (LIBOR), or another generally recognized base lending rate. Loans and debt instruments rated below investment grade are considered speculative. The fund may invest in loans of companies whose financial conditions are troubled or uncertain and that may be involved in bankruptcy proceedings, reorganizations, or financial restructurings. Some loans may be illiquid. The fund may also acquire and hold warrants and other equity interests. The fund may invest in loans, loan participations, and other securities of any maturity and duration. The fund may also invest in loans of any aggregate principal amount, which will vary from time to time.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;For purposes of reducing risk and/or improving liquidity, the fund may invest in derivative instruments such as options (including options on securities indexes) and swaps (including credit default swaps).&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is subject to risks, and you could lose money by investing in the fund. The principal risks of investing in the fund include:&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Changing distribution levels risk.&lt;/b&gt; The fund may cease or reduce the level of its distribution if income or dividends paid from its investments declines.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Distressed investments risk.&lt;/b&gt; Distressed investments, including loans, mortgages, bonds, and notes, may not be publicly traded and may involve substantial risk. A fund may lose up to its entire investment.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, options, and swaps. Options and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;High portfolio turnover risk.&lt;/b&gt; Trading securities actively and frequently can increase transaction costs (thus lowering performance) and taxable distributions.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Loan participations risk.&lt;/b&gt; Participations and assignments involve special types of risks, including credit risk, interest-rate risk, counterparty risk, liquidity risk, risks associated with extended settlement, and the risks of being a lender.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small number of issuers risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for funds which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Warrants risk.&lt;/b&gt; The prices of warrants may not precisely reflect the prices of their underlying securities. Warrant holders do not receive dividends or have voting or credit rights. A warrant ceases to have value if not exercised prior to its expiration date.&lt;/div&gt;

The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's performance. During its most recent fiscal year, the fund's portfolio turnover rate was 165% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal circumstances, the fund seeks to achieve its investment objective by investing at least 80% of its net assets (plus any borrowings for investment purposes) in stocks of small-cap companies. The fund defines small-cap companies as those that, at the time of initial purchase, have a market capitalization equal to or less than the largest company in the Russell 2000 Growth Index (approximately $6.5 billion as of October 31, 2018). The fund invests mainly in common stocks, but it may also invest in exchange-traded funds (ETFs) to a limited extent, generally for purposes of gaining temporary market exposure.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The manager employs a growth-oriented investment philosophy to analyze and select investments and seeks to own stocks of high quality companies (based on such characteristics as return-on-equity or profitability) trading at what the manager believes are attractive valuations and that are experiencing positive earnings revisions. The manager seeks to invest in companies that it believes could experience future growth rates at levels higher than the Russell 2000 Growth Index. The manager utilizes an investment process that incorporates proprietary quantitative and qualitative research.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The manager continuously monitors and evaluates its investments and attempts to mitigate risk through ownership of a well-diversified portfolio. The fund may focus its investments in a particular sector or sectors of the economy and its exposures may vary significantly from the Russell 2000 Growth Index. The fund may invest up to 10% of its total assets in foreign securities, including those in emerging markets, and may invest in initial public offerings (IPOs). The manager defines emerging markets countries as those countries included in the MSCI Emerging Markets Index.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The manager will generally sell a stock if it determines, among other things, there has been an adverse change in the company's fundamentals, competitive position, or change to its relative valuation.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Due to its investment strategy, the fund may buy and sell securities frequently, which may result in high transaction costs and additional shareholder expenses.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;

               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations.&lt;/div&gt;

               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets.&lt;/div&gt;

               &lt;b&gt;High portfolio turnover risk.&lt;/b&gt; Trading securities actively and frequently can increase transaction costs (thus lowering performance) and taxable distributions.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;

               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;

               &lt;b&gt;Small company risk.&lt;/b&gt; Small companies are generally less established and may be more volatile than larger companies. Small-capitalization securities may underperform the market as a whole.&lt;/div&gt;

The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's performance. During its most recent fiscal year, the fund's portfolio turnover rate was 25% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in the common stocks of large- and medium-sized blue chip growth companies. The manager defines blue chip growth companies as those well established in their industries and with the potential for above-average earnings growth.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;In identifying blue chip companies in which to invest, the manager generally considers whether they have viable or growing leading market positions, seasoned management teams, and strong financial fundamentals. This investment approach reflects the manager's belief that the combination of solid company fundamentals (with emphasis on the potential for above-average growth in earnings or operating cash flow) and a positive industry outlook will ultimately reward investors. The manager also seeks to invest in some companies with good prospects for dividend growth.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;While most of the assets of the fund are invested in U.S. common stocks, the fund may also invest in other types of securities, including (i) U.S. dollar- and foreign currency-denominated foreign securities (up to 20% of net assets), (ii) convertible stocks, warrants, and bonds, and (iii) futures and options. Combined investments in convertible securities, preferred stocks, and debt securities are limited to 25% of total assets. The fund may invest in debt securities of any type without regard to quality or rating, including those rated below investment-grade (junk bonds) (up to 5% of total assets). The fund's investment policies are based on credit ratings at the time of purchase. The fund's debt securities may include privately negotiated notes or loans, including loan participations and assignments (bank loans). Some loans may be illiquid.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund holds a certain portion of its assets in money market reserves consisting of shares of the T. Rowe Price Government Reserve Fund (or any other internal T. Rowe Price money market fund) or U.S. dollar- and foreign currency-denominated money market securities. These include repurchase agreements in the two highest rating categories that mature in one year or less. The fund may invest reserves in U.S. dollars and foreign currencies.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest up to 10% of its total assets in hybrid instruments. Hybrid instruments are a type of high-risk derivative which can combine the characteristics of securities, futures, and options. Such securities may bear interest or pay dividends at below market rates or even relatively nominal market rates.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;In pursuing the fund's investment objective, the manager may deviate from the fund's normal investment criteria to purchase securities the manager believes might appreciate substantially. The fund may invest significantly in the information technology sector, and the fund may at times invest significantly in stocks of technology companies.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is subject to risks, and you could lose money by investing in the fund. The principal risks of investing in the fund include:&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Currency risk.&lt;/b&gt; Fluctuations in exchange rates may adversely affect the U.S. dollar value of a fund's investments. Foreign currencies may decline in value, which could negatively impact performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;

               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: futures contracts and options. Futures contracts and options generally are subject to counterparty risk.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hybrid instrument risk.&lt;/b&gt; Hybrid instruments entail greater market risk and may be more volatile than traditional debt instruments, may bear interest or pay preferred dividends at below-market rates, and may be illiquid. The risks of investing in hybrid instruments are a combination of the risks of investing in securities, options, futures, and currencies.&lt;/div&gt;

               &lt;b&gt;Information technology risk.&lt;/b&gt; Information technology companies can be significantly affected by rapid obsolescence, short product cycles, competition, and government regulation, among other factors. Investments in the technology sector may be susceptible to heightened risk of cybersecurity breaches, which may allow an unauthorized party to gain access to personally identifiable information and other customer data.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Investment company securities risk.&lt;/b&gt; A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Loan participations risk.&lt;/b&gt; Participations and assignments involve special types of risks, including credit risk, interest-rate risk, counterparty risk, liquidity risk, risks associated with extended settlement, and the risks of being a lender.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mid-sized company risk&lt;/b&gt;. Mid-sized companies are generally less established and may be more volatile than larger companies. Mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;

               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;

               &lt;b&gt;Telecommunications sector risk.&lt;/b&gt; Telecommunication services companies are subject to government regulation of services and rates of return and can be significantly affected by intense competition, among other factors.&lt;/div&gt;

Warrant holders do not receive dividends or have voting or credit rights. A warrant ceases to have value if not exercised prior to its expiration date.&lt;/div&gt;

Please see below a hypothetical example showing the expenses of a $10,000 investment for the time periods indicated and then assuming you sell all of your shares at the end of those periods. The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's performance. During its most recent fiscal year, the fund's portfolio turnover rate was 39% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests at least 65% of its total assets in equity and equity-related securities of companies, at the time of investment, that exceed $1 billion in market capitalization and that the manager believes have above average growth prospects. These companies are generally mid-to large-capitalization companies.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The manager follows a highly disciplined investment selection and management process that seeks to identify companies that show superior absolute and relative earnings growth and also are attractively valued. The manager looks for companies that experience some or all of the following: (i) above-average revenue and earnings per share growth, (ii) strong market position, (iii) improving profitability and distinctive attributes such as unique marketing ability, (iv) strong research and development and productive new product flow, and (v) financial strength. Such companies generally trade at high prices relative to their current earnings. Earnings predictability and confidence in earnings forecasts are important parts of the selection process.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Securities in which the fund invests have historically been more volatile than the S&amp;amp;P 500 Index. Also, companies that have an earnings growth rate higher than that of the average S&amp;amp;P 500 company tend to reinvest their earnings rather than distribute them. Therefore, the fund is not likely to receive significant dividend income on its securities. Seeking to invest in companies with above market-average growth, the fund may invest significantly in sectors associated with such growth, including information technology.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;In addition to common stocks, nonconvertible preferred stock and convertible securities, equity-related securities in which the fund invests include: (i) American Depositary Receipts (ADRs); (ii) warrants and rights; (iii) investments in various types of business ventures, including partnerships and joint ventures; (iv) real estate investment trusts (REITs); and (v) initial public offerings (IPOs) and similar securities. (Convertible securities are securities &#8212;like bonds, corporate notes and preferred stocks&#8212;that the fund can convert into the company's common stock, cash value of common stock, or some other equity security.)&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;In addition to the principal strategies discussed above, the fund may also use the following investment strategies to attempt to increase the fund's return or protect its assets if market conditions warrant:&lt;/div&gt;            
            &lt;ul&gt;&lt;li&gt;                  
                  &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may make short sales of a security including short sales "against the box."&lt;/div&gt;               
               &lt;/li&gt;&lt;li&gt;                  
                  &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest up to 20% of its total assets in foreign equity securities. (For purposes of this 20% limit, ADRs and other similar receipts or shares traded in U.S. markets are not considered to be foreign securities.)&lt;/div&gt;               
               &lt;/li&gt;&lt;li&gt;                  
                  &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in U.S. government securities issued or guaranteed by the U.S. government or by an agency or instrumentality of the U.S. government.&lt;/div&gt;               
               &lt;/li&gt;&lt;li&gt;                  
                  &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in mortgage-related securities issued or guaranteed by U.S. governmental entities, including collateralized mortgage obligations, multi-class pass-through securities and stripped mortgage-backed securities.&lt;/div&gt;               
               &lt;/li&gt;&lt;li&gt;                  
                  &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in fixed-income securities rated investment grade. These include corporate debt and other debt obligations of U.S. and foreign issuers. The fund may invest in obligations that are not rated, but that the manager believes are of comparable quality to these obligations.&lt;/div&gt;               
               &lt;/li&gt;&lt;li&gt;                  
                  &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in repurchase agreements.&lt;/div&gt;               
               &lt;/li&gt;&lt;/ul&gt;
            
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The manager considers selling or reducing a stock position when, in the opinion of the manager, the stock has experienced a fundamental disappointment in earnings, it has reached an intermediate price objective and its outlook no longer seems sufficiently promising, a relatively more attractive stock emerges or the stock has experienced adverse price movement. The fund may focus its investments in a particular sector or sectors of the economy.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund's investment process may, at times, result in a higher than average portfolio turnover ratio and increased trading expenses.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is subject to risks, and you could lose money by investing in the fund. The principal risks of investing in the fund include:&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;

               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;

               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities.                   
                                       
                     The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.

               &lt;b&gt;High portfolio turnover risk.&lt;/b&gt; Trading securities actively and frequently can increase transaction costs (thus lowering performance) and taxable distributions.&lt;/div&gt;

               &lt;b&gt;Information technology risk.&lt;/b&gt; Information technology companies can be significantly affected by rapid obsolescence, short product cycles, competition, and government regulation, among other factors. Investments in the technology sector may be susceptible to heightened risk of cybersecurity breaches, which may allow an unauthorized party to gain access to personally identifiable information and other customer data.&lt;/div&gt;

               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;

               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mid-sized company risk&lt;/b&gt;. Mid-sized companies are generally less established and may be more volatile than larger companies. Mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;

Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;

The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's performance. During its most recent fiscal year, the fund's portfolio turnover rate was 277% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in a broad range of investment-grade debt securities, including U.S. government obligations, corporate bonds, mortgage-backed and other asset-backed securities and money market instruments.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund invests in debt securities that the manager believes offer attractive yields and are undervalued relative to issues of similar credit quality and interest rate sensitivity. The fund may also invest in unrated bonds that the manager believes are comparable to investment-grade debt securities. The fund may invest to a significant extent in mortgage-backed securities, including collateralized mortgage obligations.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the manager expects to maintain an effective duration within 10% (in either direction) of the duration of the Bloomberg Barclays U.S. Aggregate Bond Index (the duration of this index as of October 31, 2018 was 5.99 years).&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest:&lt;/div&gt;

               &lt;/li&gt;&lt;li&gt;                  
                  &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Up to 20% of total assets in U.S. dollar-denominated obligations of foreign issuers; and&lt;/div&gt;               
               &lt;/li&gt;&lt;li&gt;                  
                  &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Up to 10% of total assets in stripped mortgage-backed securities.&lt;/div&gt;               
               &lt;/li&gt;&lt;/ul&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;As part of a mortgage-backed securities investment strategy, the fund may enter into dollar rolls. The fund may also enter into reverse repurchase agreements to enhance return.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund's investment process may, at times, result in a higher than average portfolio turnover ratio and increased trading expenses.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is subject to risks, and you could lose money by investing in the fund. The principal risks of investing in the fund include:&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Changing distribution levels risk.&lt;/b&gt; The fund may cease or reduce the level of its distribution if income or dividends paid from its investments declines.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: futures contracts, reverse repurchase agreements, and options. Futures contracts and options generally are subject to counterparty risk. An event of default or insolvency of the counterparty to a reverse repurchase agreement could result in delays or restrictions with respect to the fund's ability to dispose of the underlying securities. In addition, a reverse repurchase agreement may be considered a form of leverage and may, therefore, increase fluctuations in the fund's net asset value per share (NAV).&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;High portfolio turnover risk.&lt;/b&gt; Trading securities actively and frequently can increase transaction costs (thus lowering performance) and taxable distributions.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;

Please see below a hypothetical example showing the expenses of a $10,000 investment for the time periods indicated and then assuming you sell all of your shares at the end of those periods. The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's performance. During its most recent fiscal year, the fund's portfolio turnover rate was 19% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in equity securities, with at least 65% in common stocks of well-established companies paying above-average dividends. The fund employs a "value" approach and invests in stocks and other securities that appear to be undervalued by various measures but have good prospects for capital appreciation and dividend growth.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, substantial dividend income means that the yield on the fund's portfolio securities generally exceeds the yield on the fund's benchmark. The manager believes that income can contribute significantly to total return over time and expects the fund's yield to exceed that of the Russell 1000 Value Index. While the price of a company's stock can go up or down, stocks paying a high level of dividend income tend to be less volatile than those paying a lower level and may help offset losses in falling markets.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund will generally consider companies with established operating histories, above-average dividend yield or low price/earnings ratios relative to the Russell 1000 Value Index, positive financial characteristics, and/or low stock price relative to a company's underlying value. The fund may also purchase other types of securities in keeping with its objective, including: (i) U.S. dollar-and foreign currency-denominated foreign securities (up to 25% of total assets); (ii) preferred stocks; (iii) convertible stocks, bonds, and warrants; (iv) futures and options; and (v) bank debt, loan participations, and assignments.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in fixed-income securities without regard to quality or rating, including privately negotiated notes or loans (including loan participations and assignments (bank loans)) and up to 10% in below-investment-grade fixed-income securities (junk bonds). The fund's fixed-income investments may include privately negotiated notes or loans, including loan participations and assignments (bank loans). Some loans may be illiquid.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund holds a certain portion of its assets in money market reserves consisting of shares of the T. Rowe Price Government Reserve Fund (or any other internal T. Rowe Price money market fund) or U.S. dollar- and foreign currency-denominated money market securities. These include repurchase agreements in the two highest rating categories that mature in one year or less. The fund may invest reserves in U.S. dollars and foreign currencies.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest up to 10% of its total assets in hybrid instruments. Hybrid instruments are a type of high-risk derivative which can combine the characteristics of securities, futures, and options. Such securities may bear interest or pay dividends at below market rates or even relatively nominal market rates.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;In pursuing the fund's investment objective, the manager may deviate from the fund's normal investment criteria to purchase securities the manager believes might appreciate substantially. The fund may invest significantly in certain sectors, such as the financials sector.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is subject to risks, and you could lose money by investing in the fund. The principal risks of investing in the fund include:&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Changing distribution levels risk.&lt;/b&gt; The fund may cease or reduce the level of its distribution if income or dividends paid from its investments declines.&lt;/div&gt;

               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Currency risk.&lt;/b&gt; Fluctuations in exchange rates may adversely affect the U.S. dollar value of a fund's investments. Foreign currencies may decline in value, which could negatively impact performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: futures contracts and options. Futures contracts and options generally are subject to counterparty risk.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hybrid instrument risk.&lt;/b&gt; Hybrid instruments entail greater market risk and may be more volatile than traditional debt instruments, may bear interest or pay preferred dividends at below-market rates, and may be illiquid. The risks of investing in hybrid instruments are a combination of the risks of investing in securities, options, futures, and currencies.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Investment company securities risk.&lt;/b&gt; A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Loan participations risk.&lt;/b&gt; Participations and assignments involve special types of risks, including credit risk, interest-rate risk, counterparty risk, liquidity risk, risks associated with extended settlement, and the risks of being a lender.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;

               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors. To the extent that a fund invests in securities of companies in the financial services sector, the fund may be significantly affected by economic, market, and business developments, borrowing costs, interest-rate fluctuations, competition, and government regulation, among other factors, impacting that sector.&lt;/div&gt;

Past performance (before and after taxes) does not indicate future results. The S&amp;amp;P 500 Index shows how the fund's performance compares against the returns of similar investments. All figures assume dividend reinvestment.

A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's performance. During its most recent fiscal year, the fund's portfolio turnover rate was 31% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in fixed-income instruments that are economically tied to at least three countries (one of which may be the United States), which may be represented by futures contracts (including related options) with respect to such securities, and options on such securities. These fixed-income instruments may be denominated in foreign currencies or in U.S. dollars, which may be represented by forwards or derivatives, such as options, futures contracts, or swap agreements.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;In selecting securities for the fund, the manager utilizes economic forecasting, interest rate anticipation, credit and call risk analysis, foreign currency exchange rate forecasting, and other security selection techniques. The proportion of the fund's assets committed to investment in securities with particular characteristics (such as maturity, type and coupon rate) will vary based on the manager's outlook for the U.S. and foreign economies, the financial markets, and other factors.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Fixed-income securities may have fixed, variable, or floating rates of interest, including rates of interest that vary inversely at a multiple of a designated or floating rate, or that vary according to change in relative values of currencies.&lt;/div&gt;  
           
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Depending on the manager's current opinion as to the proper allocation of assets among domestic and foreign issuers, investments that are economically tied to foreign countries will normally be at least 25% of the fund's net assets. The fund may invest, without limitation, in securities and instruments that are economically tied to emerging countries. The fund may invest up to 20% of its total assets in fixed-income securities that are rated below investment grade of any rating. The fund's investment policies are based on credit ratings at the time of purchase. The fund may invest in baskets of foreign currencies (such as the euro) and directly in currencies. The average portfolio duration of the fund normally varies within three years (plus or minus) of the duration of the benchmark index, as calculated by the manager.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest up to 10% of its total assets in preferred stocks. The fund may have significant investments in fixed-income instruments issued by companies in the financial services sector.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund's investment process may, at times, result in a higher than average portfolio turnover ratio and increased trading expenses.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may make short sales of a security including short sales "against the box."&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is a non-diversified fund, which means that it may invest in a smaller number of issuers than a diversified fund and may invest more of its assets in the securities of a single issuer.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may:&lt;/div&gt;

               &lt;/li&gt;&lt;li&gt;                  
                  &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;purchase and sell futures and options on futures,&lt;/div&gt;               
               &lt;/li&gt;&lt;li&gt;                  
                  &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;purchase and sell currency or securities on a forward basis, and&lt;/div&gt;               
               &lt;/li&gt;&lt;li&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is subject to risks, and you could lose money by investing in the fund. The principal risks of investing in the fund include:&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Changing distribution levels risk.&lt;/b&gt; The fund may cease or reduce the level of its distribution if income or dividends paid from its investments declines.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Currency risk.&lt;/b&gt; Fluctuations in exchange rates may adversely affect the U.S. dollar value of a fund's investments. Foreign currencies may decline in value, which could negatively impact performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, foreign currency swaps, total return swaps, futures contracts, options on futures, interest-rate swaps, inverse floating-rate securities, options, reverse repurchase agreements, and swaps. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk. An event of default or insolvency of the counterparty to a reverse repurchase agreement could result in delays or restrictions with respect to the fund's ability to dispose of the underlying securities. In addition, a reverse repurchase agreement may be considered a form of leverage and may, therefore, increase fluctuations in the fund's net asset value per share (NAV).&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;High portfolio turnover risk.&lt;/b&gt; Trading securities actively and frequently can increase transaction costs (thus lowering performance) and taxable distributions.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hybrid instrument risk.&lt;/b&gt; Hybrid instruments entail greater market risk and may be more volatile than traditional debt instruments, may bear interest or pay preferred dividends at below-market rates, and may be illiquid. The risks of investing in hybrid instruments are a combination of the risks of investing in securities, options, futures, and currencies.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Loan participations risk.&lt;/b&gt; Participations and assignments involve special types of risks, including credit risk, interest-rate risk, counterparty risk, liquidity risk, risks associated with extended settlement, and the risks of being a lender.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors. To the extent that a fund invests in securities of companies in the financial services sector, the fund may be significantly affected by economic, market, and business developments, borrowing costs, interest-rate fluctuations, competition, and government regulation, among other factors, impacting that sector.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Short sales risk.&lt;/b&gt; In a short sale, a fund pays interest on the borrowed security. The fund will lose money if the security price increases between the short sale and the replacement date.&lt;/div&gt;

Past performance (before and after taxes) does not indicate future results. All figures assume dividend reinvestment. Performance information is updated daily, monthly, and quarterly and may be obtained at our website, jhinvestments.com, or by calling 800-344-1029 between 8:00 A.M. and 7:00 P.M., Eastern time, on most business days.&lt;/div&gt;

Your actual after-tax returns may be different. After-tax returns are not relevant to shares held in an IRA, 401(k), or other tax-advantaged investment plan.&lt;/div&gt;

A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's performance. During its most recent fiscal year, the fund's portfolio turnover rate was 60% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests at least 80% of its net assets (plus any borrowings for investment purposes) at the time of investment in high yield securities. The fund's investments may include corporate bonds, preferred stocks, U.S. government and foreign securities, mortgage-backed securities, loan assignments or participations and convertible securities which have the following ratings (or, if unrated, are considered by the manager to be of equivalent quality):&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Below-investment-grade securities are commonly referred to as "junk bonds." The fund may also invest in investment-grade securities.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;As part of its investment strategy, the fund will generally invest without restrictions within these ratings category ranges, or in unrated securities considered to be of equivalent quality by the manager.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in foreign bonds and other fixed-income securities denominated in foreign currencies, where, in the opinion of the manager, the combination of current yield and currency value offer attractive expected returns. Foreign securities in which the fund may invest include emerging market securities. The fund may invest up to 100% of its assets in foreign securities.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may also enter into various derivative transactions for both hedging and non-hedging purposes, including for purposes of enhancing returns. These derivative transactions include, but are not limited to, futures, options, swaps and forwards. In particular, the fund may use interest rate swaps, credit default swaps (on individual securities and/or baskets of securities), futures contracts and/or mortgage-backed securities to a significant extent, although the amounts invested in these instruments may change from time to time.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in fixed- and floating-rate loans, generally in the form of loan participations and assignments of such loans.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund normally maintains an average portfolio duration of between three and seven years. However, the fund may invest in individual securities of any duration. Duration is an approximate measure of the sensitivity of the market value of a security to changes in interest rates.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is subject to risks, and you could lose money by investing in the fund. The principal risks of investing in the fund include:&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Changing distribution levels risk.&lt;/b&gt; The fund may cease or reduce the level of its distribution if income or dividends paid from its investments declines.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, futures contracts, options, swaps and interest-rate swaps. Futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Loan participations risk.&lt;/b&gt; Participations and assignments involve special types of risks, including credit risk, interest-rate risk, counterparty risk, liquidity risk, risks associated with extended settlement, and the risks of being a lender.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;This example is intended to help you compare the cost of investing in the fund with the cost of investing in other mutual funds. Please see below a hypothetical example showing the expenses of a $10,000 investment for the time periods indicated and then assuming you sell all of your shares at the end of those periods. The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's performance. During its most recent fiscal year, the fund's portfolio turnover rate was 30% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in investments of smaller companies outside the U.S., including emerging markets, which have total stock market capitalizations or annual revenues of $4 billion or less.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;In some emerging markets, the fund may invest in companies that qualify as smaller companies but that still are among the largest in the market. The fund may also invest in depository receipts and may invest a portion of its assets in the equity securities of larger foreign companies.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;An equity security, or stock, represents a proportionate share of the ownership of a company; its value is based on the success of the company's business, any income paid to stockholders, the value of its assets, and general market conditions. Common stocks, preferred stocks and convertible securities are examples of equity securities. Convertible securities generally are debt securities or preferred stock that may be converted into common stock after a certain time period or under certain circumstances.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest more than 25% of its total assets in the securities of issuers located in any one country. The fund may focus its investments in a particular sector or sectors of the economy.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;When choosing equity investments for this fund, the manager applies a "bottom up," value-oriented, long-term approach, focusing on the market price of a company's securities relative to the manager's evaluation of the company's long-term earnings, asset value and cash flow potential. The manager also considers a company's price/earnings ratio, profit margins and liquidation value and other factors.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is subject to risks, and you could lose money by investing in the fund. The principal risks of investing in the fund include:&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's performance. During its most recent fiscal year, the fund's portfolio turnover rate was 29% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests primarily in equity securities of companies located outside the U.S., including in emerging markets. Although the manager will search for investments across a large number of countries and sectors, from time to time, based on economic conditions, the fund may have significant positions in particular countries or sectors such as technology (including computer hardware and software, electronics, and telecommunications) and financial institutions.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Equity securities generally entitle the holder to participate in a company's general operating results. These include common stocks and preferred stocks. The fund also invests in American Depositary Receipts (ADRs), European Depositary Receipts (EDRs) and Global Depositary Receipts (GDRs), which are certificates typically issued by a bank or trust company that give their holders the right to receive securities issued by a foreign or domestic company.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in debt securities of countries and governments located anywhere in the world, as well as in equity-linked notes.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The manager's investment philosophy is "bottom-up," value-oriented, and long-term. In choosing equity investments, the manager will focus on the market price of a company's securities relative to its evaluation of the company's long-term earnings, asset value and cash flow potential. A company's historical value measure, including price/earnings ratio, profit margins and liquidation value, will also be considered.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: equity-linked notes (equity-linked notes generally reflect the risks associated with their underlying securities, depend on the credit of the note's issuer, may be privately placed, and may have a limited secondary market). &lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors. To the extent that a fund invests in securities of companies in the financial services sector, the fund may be significantly affected by economic, market, and business developments, borrowing costs, interest-rate fluctuations, competition, and government regulation, among other factors, impacting that sector.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;

This style of investing is subject to the risk that the valuations never improve or that the returns on value equity securities are less than returns on other styles of investing or the overall stock market. Value stocks also may decline in price, even though in theory they are already underpriced.&lt;/div&gt;

A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's performance. During its most recent fiscal year, the fund's portfolio turnover rate was 67% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in equity securities of medium-sized companies with significant capital appreciation potential. For the fund, "medium-sized companies" are those with market capitalizations within the collective market capitalization range of companies represented in either the Russell Mid Cap Index ($517.2 million to $37.0 billion as of October 31, 2018) or the S&amp;amp;P Mid Cap 400 Index ($177.8 million to $11.6 billion as of October 31, 2018).&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The manager's investment approach is based primarily on proprietary fundamental analysis. Fundamental analysis involves the assessment of a company through such factors as its business environment, management, balance sheet, income statement, anticipated earnings, revenues and other related measures of value. In analyzing companies for investment, the manager looks for, among other things, a strong balance sheet, strong earnings growth, attractive industry dynamics, strong competitive advantages (e.g., strong management teams), and attractive relative value within the context of a security's primary trading market. Securities are sold when the investment has achieved its intended purpose, or because it is no longer considered attractive. The fund may invest up to 25% of its total assets in foreign securities, including emerging market securities. The fund may focus its investments in a particular sector or sectors of the economy.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund's investment process may, at times, result in a higher than average portfolio turnover ratio and increased trading expenses.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is subject to risks, and you could lose money by investing in the fund. The principal risks of investing in the fund include:&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;High portfolio turnover risk.&lt;/b&gt; Trading securities actively and frequently can increase transaction costs (thus lowering performance) and taxable distributions.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mid-sized company risk&lt;/b&gt;. Mid-sized companies are generally less established and may be more volatile than larger companies. Mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Privately held and newly public companies risk.&lt;/b&gt; Investments in the stocks of privately held companies and newly public companies involve greater risks than investments in stocks of companies that have traded publicly on an exchange for extended time periods. Investments in such companies are less liquid and may be difficult to value. There may be significantly less information available about these companies' business models, quality of management, earnings growth potential, and other criteria used to evaluate their investment prospects. The extent (if at all) to which securities of privately held companies or newly public companies may be sold without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Funds with principal investment strategies that involve investments in securities of privately held companies tend to have a greater exposure to liquidity risk than funds that do not invest in securities of privately held companies.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;

Past performance (before and after taxes) does not indicate future results. All figures assume dividend reinvestment. Performance information is updated daily, monthly, and quarterly and may be obtained at our website, jhinvestments.com, or by calling 800-344-1029 between 8:00 A.M. and 7:00 P.M., Eastern time, on most business days.&lt;/div&gt;

Your actual after-tax returns may be different. After-tax returns are not relevant to shares held in an IRA, 401(k), or other tax-advantaged investment plan.&lt;/div&gt;

Please see below a hypothetical example showing the expenses of a $10,000 investment for the time periods indicated and then assuming you sell all of your shares at the end of those periods. The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's performance. During its most recent fiscal year, the fund's portfolio turnover rate was 52% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund invests primarily in equity securities of companies considered small-capitalization companies by the fund's managers. The fund also invests in mid-cap and micro-cap companies and reserves the right to invest in companies of any market-capitalization including large-cap companies. Market-capitalization classification is determined at the time of purchase by each manager using its own investment criteria. The market-capitalization of individual portfolio securities and the fund's portfolio as a whole will vary over time as market conditions change.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund invests in equity securities, including common stock, preferred stock and equity-equivalent securities or instruments whose values are based on common stocks, such as convertible securities, rights, warrants or options (stock or stock index), futures contracts (stock or stock index), and index swaps.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund employs a multi style and multi manager approach in which portions of the fund's assets are allocated to different managers that employ distinct investment styles. The fund currently has three managers. The fund's advisor provides or oversees the provision of all investment advisory and portfolio management services for the fund, including overseeing the investment allocation for the fund and managing the fund's overall portfolio characteristics, including investment style exposures.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The advisor selects managers for the fund, allocates fund assets among and oversees those managers, and evaluates their performance results. The managers select the individual portfolio securities for the assets assigned to them. The advisor considers various characteristics of the manager's portfolio when allocating assets: market capitalization, growth and profitability, valuation, sector weightings, and earnings and price volatility. The advisor also considers the correlation between the managers' historical and expected investment returns. Since the advisor will rebalance the fund only periodically, the actual portion of the fund managed by each manager at any given time will vary.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in and potentially emphasize any economic sector. The fund may also invest in growth or value equity securities. Growth securities are securities a manager believes will experience relatively rapid earnings growth. Value securities, on the other hand, are securities a manager believes are selling at prices below their fundamental value.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund also may invest in: (a) securities of foreign issuers, including foreign issuers located in emerging markets, either directly through investments in foreign currency-denominated securities traded outside of the United States or indirectly through depositary receipts; (b) real estate investment trusts (REITs); (c) initial public offerings (IPOs); and (d) master limited partnerships (MLPs). The fund may invest in derivatives such as swaps, options, futures contracts, or options on futures contracts to gain market exposure, to adjust market exposure, or to maintain liquidity to pay redemptions. The fund may invest in foreign currency forward contracts to manage the fund's exposure to foreign currency. The fund also may invest in investment companies, including exchange-traded funds (ETFs) for the purpose of gaining exposure to equity markets while maintaining liquidity.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is subject to risks, and you could lose money by investing in the fund. The principal risks of investing in the fund include:&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: foreign currency forward contracts, futures contracts, options on futures, options, and swaps. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Investment company securities risk.&lt;/b&gt; A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Master limited partnership risk.&lt;/b&gt; MLPs generally reflect the risks associated with their underlying assets and with pooled investment vehicles. MLPs with credit-related holdings are subject to interest-rate risk and risk of default.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Multi manager risk.&lt;/b&gt; The management teams' investment styles may not complement each other as intended. A multi manager approach could result in more exposure to certain types of securities and higher portfolio turnover.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Real estate investment trust risk.&lt;/b&gt; REITs, pooled investment vehicles that typically invest in real estate directly or in loans collateralized by real estate, carry risks associated with owning real estate, including the potential for a decline in value due to economic or market conditions.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Real estate securities risk.&lt;/b&gt; Securities of companies in the real estate industry carry risks associated with owning real estate, including the potential for a decline in value due to economic or market conditions.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized (including microcap) companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Warrants risk.&lt;/b&gt; The prices of warrants may not precisely reflect the prices of their underlying securities. Warrant holders do not receive dividends or have voting or credit rights. A warrant ceases to have value if not exercised prior to its expiration date.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The following information illustrates the variability of the fund's returns and provides some indication of the risks of investing in the fund by showing changes in the fund's performance from year to year and by showing how the fund's average annual returns compared with a broad-based market index. Past performance (before and after taxes) does not indicate future results. All figures assume dividend reinvestment. Performance information is updated daily, monthly, and quarterly and may be obtained at our website, jhinvestments.com, or by calling 800-344-1029 between 8:00 A.M. and 7:00 P.M., Eastern time, on most business days.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Prior to September 27, 2014, the fund was managed solely by Dimensional Fund Advisors LP and another subadvisor pursuant to a different investment strategy. The performance presented prior to this date should not be attributed to Brandywine Global Investment Management, LLC (Brandywine) or GW&amp;amp;K Investment Management, LLC (GW&amp;amp;K).&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Effective June 1, 2015, the fund eliminated its policy of investing at least 80% of its net assets (plus any borrowings for investment purposes) in equity securities of small capitalization companies and adopted other investment strategy changes. The performance information presented for periods prior to June 1, 2015, reflects management of the fund consistent with investment strategies in effect during those periods (and without Brandywine and GW&amp;amp;K) and might have been different if the fund's investments had been managed under its current investment strategies by all of its current managers.&lt;/div&gt;

The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's performance. During its most recent fiscal year, the fund's portfolio turnover rate was 158% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in equity securities of real estate investment trusts ("REITs") and real estate companies. Equity securities include common stock, preferred stock and securities convertible into common stock.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;A company is considered to be a real estate company if, in the opinion of the manager, at least 50% of its revenues or 50% of the market value of its assets at the time its securities are purchased by the fund are attributed to the ownership, construction, management or sale of real estate.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The manager looks for real estate securities it believes will provide superior returns to the fund, and attempts to focus on companies with the potential for stock price appreciation and a record of paying dividends.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;To find these issuers, the manager tracks economic conditions and real estate market performance in major metropolitan areas and analyzes performance of various property types within those regions. To perform this analysis, it uses information from a nationwide network of real estate professionals to evaluate the holdings of real estate companies and REITs in which the fund may invest. Its analysis also includes the companies' management structure, financial structure and business strategy. The goal of these analyses is to determine which of the issuers the manager believes will be the most profitable to the fund. The manager also considers the effect of the real estate securities markets in general when making investment decisions. The manager does not attempt to time the market.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;A REIT invests primarily in income-producing real estate or makes loans to persons involved in the real estate industry.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Some REITs, called equity REITs, buy real estate and pay investors income from the rents received from the real estate owned by the REIT and from any profits on the sale of its properties. Other REITs, called mortgage REITs, lend money to building developers and other real estate companies and pay investors income from the interest paid on those loans. There are also hybrid REITs which engage in both owning real estate and making loans.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;If a REIT meets certain requirements, it is not taxed on the income it distributes to its investors.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may realize some short-term gains or losses if the manager chooses to sell a security because it believes that one or more of the following is true:&lt;/div&gt;            
            &lt;ul&gt;&lt;li&gt;                  
                  &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;A security is not fulfilling its investment purpose;&lt;/div&gt;               
               &lt;/li&gt;&lt;li&gt;                  
                  &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;A security has reached its optimum valuation; or&lt;/div&gt;               
               &lt;/li&gt;&lt;li&gt;                  
                  &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;A particular company or general economic conditions have changed.&lt;/div&gt;               
               &lt;/li&gt;&lt;/ul&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Based on its recent practices, the manager expects that the fund's assets will be invested primarily in equity REITs. In changing market conditions, the fund may invest in other types of REITs.&lt;/div&gt;            
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;When the manager believes that it is prudent, the fund may invest a portion of its assets in other types of securities. These securities may include convertible securities, short-term securities, bonds, notes, securities of companies not principally engaged in the real estate industry, non-leveraged stock index futures contracts and other similar securities. (Stock index futures contracts, can help the fund's cash assets remain liquid while performing more like stocks.)&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest up to 10% of its total assets in securities of foreign real estate companies.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is a non-diversified fund, which means that it may invest in a smaller number of issuers than a diversified fund and may invest more of its assets in the securities of a single issuer.  The fund concentrates its investments in securities of issuers in the real estate industry.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is subject to risks, and you could lose money by investing in the fund. The principal risks of investing in the fund include:&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Concentration risk.&lt;/b&gt; Because the fund may focus on one or more industries or sectors of the economy, its performance depends in large part on the performance of those sectors or industries. As a result, the value of an investment may fluctuate more widely than it would in a fund that is diversified across industries and sectors. A downturn in the real estate industry may significantly detract from performance.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: futures contracts. Futures contracts generally are subject to counterparty risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;High portfolio turnover risk.&lt;/b&gt; Trading securities actively and frequently can increase transaction costs (thus lowering performance) and taxable distributions.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Real estate investment trust risk.&lt;/b&gt; REITs, pooled investment vehicles that typically invest in real estate directly or in loans collateralized by real estate, carry risks associated with owning real estate, including the potential for a decline in value due to economic or market conditions.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Real estate securities risk.&lt;/b&gt; Securities of companies in the real estate industry carry risks associated with owning real estate, including the potential for a decline in value due to economic or market conditions.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The following information illustrates the variability of the fund's returns and provides some indication of the risks of investing in the fund by showing changes in the fund's performance from year to year and by showing how the fund's average annual returns compared with a broad-based market index. Past performance (before and after taxes) does not indicate future results. All figures assume dividend reinvestment. Performance information is updated daily, monthly, and quarterly and may be obtained at our website, jhinvestments.com, or by calling 800-344-1029 between 8:00 A.M. and 7:00 P.M., Eastern time, on most business days.&lt;/div&gt;

Because Class NAV shares of the fund had not commenced operations as of the date of this prospectus, the returns shown are those of Class 1 shares. Returns for Class NAV shares would have been substantially similar to returns of Class 1 shares because each share class is invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.&lt;/div&gt;

Your actual after-tax returns may be different. After-tax returns are not relevant to shares held in an IRA, 401(k), or other tax-advantaged investment plan.&lt;/div&gt;

Please see below a hypothetical example showing the expenses of a $10,000 investment for the time periods indicated and then assuming you sell all of your shares at the end of those periods. The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's performance. During its most recent fiscal year, the fund's portfolio turnover rate was 46% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests at least 80% of its net assets (plus borrowings for investment purposes) in inflation-indexed bonds of varying maturities issued by the U.S. and foreign governments, their agencies or instrumentalities and corporations, which may be represented by forwards or derivatives such as options, futures contracts, or swap agreements.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Inflation-indexed bonds are fixed-income securities that are structured to provide protection against inflation. The value of the bond's principal or the interest income paid on the bond is adjusted to track changes in an official inflation measure. The U.S. Treasury uses the Consumer Price Index for Urban Consumers as the inflation measure. Inflation-indexed bonds issued by a foreign government are generally adjusted to reflect a comparable inflation index, calculated by that government. "Real return" equals total return less the estimated cost of inflation, which is typically measured by the change in an official inflation measure.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The types of fixed-income securities in which the fund may invest include the following securities which, unless otherwise noted, may be issued by domestic or foreign issuers and may be denominated in U.S. dollars or foreign currencies:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Fixed-income securities may have fixed, variable, or floating rates of interest, including rates of interest that vary inversely at a multiple of a designated or floating rate, or that vary according to change in relative values of currencies.&lt;/div&gt;            
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund invests primarily in investment-grade securities, but may invest up to 10% of its total assets in high yield securities ("junk bonds") rated B or higher by Moody's Investors Service, Inc. or equivalently rated by Standard and Poor's Ratings Services or Fitch Ratings Inc., or, if unrated, determined by the manager to be of comparable quality. The fund's investment policies are based on credit ratings at the time of purchase. The fund may also invest up to 30% of its total assets in securities denominated in foreign currencies, and may invest beyond this limit in U.S. dollar-denominated securities of foreign issuers. The fund may invest in baskets of foreign currencies (such as the euro) and direct currency. The fund will normally limit its foreign currency exposure (from foreign currency-denominated securities or foreign currencies) to 20% of its total assets. The fund may invest up to 10% of its total assets in securities and instruments that are economically tied to emerging market countries. This limitation does not apply to investment grade sovereign debt denominated in the local currency with less than 1 year remaining to maturity. The effective duration of this fund normally varies within three years (plus or minus) of the duration of the benchmark, as calculated by the manager.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest up to 10% of its total assets in preferred stocks.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may also lend its portfolio securities to brokers, dealers and other financial institutions to earn income. The fund may, without limitation, seek to obtain market exposure to the securities in which it primarily invests by entering into a series of purchase and sale contracts or by using other investment techniques (such as buy backs or dollar rolls).&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund's investment process may, at times, result in a higher than average portfolio turnover ratio and increased trading expenses.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may make short sales of a security including short sales "against the box."&lt;/div&gt;

U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;

Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;

Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;

               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, foreign currency swaps, futures contracts, options on futures, interest-rate swaps, total return swaps, inverse floating-rate securities, swaps, options, and reverse repurchase agreements. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk. An event of default or insolvency of the counterparty to a reverse repurchase agreement could result in delays or restrictions with respect to the fund's ability to dispose of the underlying securities, in addition, a reverse repurchase agreement may be considered a form of leverage and may, therefore, increase fluctuations in the fund's net asset value per share (NAV).&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;High portfolio turnover risk.&lt;/b&gt; Trading securities actively and frequently can increase transaction costs (thus lowering performance) and taxable distributions.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hybrid instrument risk.&lt;/b&gt; Hybrid instruments entail greater market risk and may be more volatile than traditional debt instruments, may bear interest or pay preferred dividends at below-market rates, and may be illiquid. The risks of investing in hybrid instruments are a combination of the risks of investing in securities, options, futures, and currencies.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Inflation-linked security risk.&lt;/b&gt; Inflation-linked debt securities are subject to the effects of changes in market interest rates caused by factors other than inflation (real interest rates). In general, the price of an inflation-linked security tends to decline when real interest rates increase. Unlike conventional bonds, the principal and interest payments of inflation-linked securities such as TIPS are adjusted periodically to a specified rate of inflation (e.g., Non-Seasonally Adjusted Consumer Price Index for all Urban Consumers (CPI-U)). There can be no assurance that the inflation index used will accurately measure the real rate of inflation. These securities may lose value in the event that the actual rate of inflation is different than the rate of the inflation index.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Loan participations risk.&lt;/b&gt; Participations and assignments involve special types of risks, including credit risk, interest-rate risk, counterparty risk, liquidity risk, risks associated with extended settlement, and the risks of being a lender.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Municipal bond risk.&lt;/b&gt; The prices of municipal bonds, including general obligation bonds, can decline if the issuer's credit quality declines. Revenue bond prices can decline if related projects become unprofitable. An insured municipal bond is subject to the risk that the insurer may be unable to pay claims and is not insured with respect to the market value of the obligation. Municipal bond income could become taxable in the future. Investments in AMT bonds may result in tax liability for shareholders.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Short sales risk.&lt;/b&gt; In a short sale, a fund pays interest on the borrowed security. The fund will lose money if the security price increases between the short sale and the replacement date.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

Please see below a hypothetical example showing the expenses of a $10,000 investment for the time periods indicated and then assuming you sell all of your shares at the end of those periods. The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's performance. During its most recent fiscal year, the fund's portfolio turnover rate was 31% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in companies with market capitalizations, at the time of investment, that do not exceed the maximum market capitalization of any security in the Russell 2000 Index ($13.0 million to $6.3 billion as of October 31, 2018).&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund invests in small companies whose common stocks are believed to be undervalued. The market capitalization of the companies in the fund's portfolio and the Russell 2000 Index changes over time, and the fund will not sell a stock just because the company has grown to a market capitalization outside the range. The fund may, on occasion, purchase companies with a market capitalization above the range.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Reflecting a value approach to investing, the fund will seek the stocks of companies whose current stock prices do not appear to adequately reflect their underlying value as measured by assets, earnings, cash flow, or business franchises. The manager's in-house research team seeks to identify companies that appear to be undervalued by various measures, and may be temporarily out of favor, but have good prospects for capital appreciation. In selecting investments, they generally look for some of the following factors:&lt;/div&gt;            
            &lt;ul&gt;&lt;li&gt;                  
                  &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Low price/earnings, price/book value or price/cash flow ratios relative to the Russell 2000 Index, the company's peers or its own historic norm;&lt;/div&gt;               
               &lt;/li&gt;&lt;li&gt;                  
                  &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Low stock price relative to a company's underlying asset values;&lt;/div&gt;               
               &lt;/li&gt;&lt;li&gt;                  
                  &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Above-average dividend yield relative to a company's peers or its own historic norm;&lt;/div&gt;               
               &lt;/li&gt;&lt;li&gt;                  
                  &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;A plan to improve the business through restructuring; and/or&lt;/div&gt;               
               &lt;/li&gt;&lt;li&gt;                  
                  &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;A sound balance sheet and other positive financial characteristics.&lt;/div&gt;               
               &lt;/li&gt;&lt;/ul&gt;            
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;While most assets will be invested in U.S. common stocks, including real estate investment trusts (REITs) that pool money to invest in properties and mortgages, the fund may purchase other securities, including foreign securities (up to 20% of its total assets), futures, and options. The fund may invest in fixed-income and convertible securities without restrictions on quality or rating, including up to 10% of total assets in below-investment-grade fixed-income securities ("junk bonds"). The fund's fixed income investments may include privately negotiated notes or loans, including loan participations and assignments ("bank loans"). These investments in bank loans will be made only in companies, municipalities or entities that meet the fund's investment criteria. Some loans may be illiquid. Since the fund invests primarily in equity securities, the risks associated with fixed-income securities will not affect the fund as much as they would a fund that invests more of its assets in fixed-income securities.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund holds a certain portion of its assets in money market reserves which can consist of shares of the T. Rowe Price Government Reserve Fund (or any other internal T. Rowe Price money market fund) as well as U.S. and foreign currency denominated money market securities, including repurchase agreements, in the two highest rating categories, maturing in one year or less. The fund may invest reserves in U.S. dollars and foreign currencies.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may sell securities for a variety of reasons, such as to secure gains, limit losses or redeploy assets into more promising opportunities.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest up to 10% of its total assets in hybrid instruments. Hybrid instruments are a type of high-risk derivatives which can combine the characteristics of securities, futures and options. Such securities may bear interest or pay dividends at below (or even relatively nominal) rates. The fund may also invest in options and enter into futures contracts. The fund may at times invest significantly in certain sectors, such as the financials sector.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is subject to risks, and you could lose money by investing in the fund. The principal risks of investing in the fund include:&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Convertible securities risk.&lt;/b&gt; The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. As the market price of underlying common stock declines below the conversion price, the market value of the convertible security tends to be increasingly influenced by its yield.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Currency risk.&lt;/b&gt; Fluctuations in exchange rates may adversely affect the U.S. dollar value of a fund's investments. Foreign currencies may decline in value, which could negatively impact performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: futures contracts and options. Futures contracts and options generally are subject to counterparty risk.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hybrid instrument risk.&lt;/b&gt; Hybrid instruments entail greater market risk and may be more volatile than traditional debt instruments, may bear interest or pay preferred dividends at below-market rates, and may be illiquid. The risks of investing in hybrid instruments are a combination of the risks of investing in securities, options, futures, and currencies.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Investment company securities risk.&lt;/b&gt; A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;

               &lt;b&gt;Loan participations risk.&lt;/b&gt; Participations and assignments involve special types of risks, including credit risk, interest-rate risk, counterparty risk, liquidity risk, risks associated with extended settlement, and the risks of being a lender.&lt;/div&gt;

               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Real estate investment trust risk.&lt;/b&gt; REITs, pooled investment vehicles that typically invest in real estate directly or in loans collateralized by real estate, carry risks associated with owning real estate, including the potential for a decline in value due to economic or market conditions.&lt;/div&gt;

               &lt;b&gt;Real estate securities risk.&lt;/b&gt; Securities of companies in the real estate industry carry risks associated with owning real estate, including the potential for a decline in value due to economic or market conditions.&lt;/div&gt;

               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors. To the extent that a fund invests in securities of companies in the financial services sector, the fund may be significantly affected by economic, market, and business developments, borrowing costs, interest-rate fluctuations, competition, and government regulation, among other factors, impacting that sector.&lt;/div&gt;

               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

               &lt;b&gt;Value investing style risk.&lt;/b&gt; The fund emphasizes a value style of investing, which focuses on undervalued companies with characteristics for improved valuations. This style of investing is subject to the risk that the valuations never improve or that the returns on value equity securities are less than returns on other styles of investing or the overall stock market. Value stocks also may decline in price, even though in theory they are already underpriced.&lt;/div&gt;

A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's performance. During its most recent fiscal year, the fund's portfolio turnover rate was 51% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The manager actively manages a diversified portfolio of below-investment-grade debt securities. The manager does not manage the portfolio to a specific maturity or duration. The manager focuses on individual security selection (primarily using a "bottom-up" approach) and seeks to identify high yield securities that appear comparatively undervalued. The manager uses its knowledge of various industries to assess the risk/return tradeoff among issuers within particular industries, in seeking to identify compelling relative value investments. The manager analyzes the issuers' long-term prospects and focuses on characteristics such as management, asset coverage, free cash flow generation, liquidity and business risk. The manager's research and analysis highlights industry drivers, competitive position and operating trends with an emphasis on free cash flow. The manager also talks to management, and consults industry contacts, debt and equity analysts, and rating agencies.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The manager purchases securities for the fund when attractive risk/reward ideas are identified and sells securities when either the securities become overvalued or circumstances change in a way that adversely affects this risk/return profile. Rigorous credit analysis of individual issuers is an integral part of the selection process. The manager attempts to invest in high yield securities of issuers which it believes have ample asset coverage for their debt securities in comparison to other high yield security issuers in an effort to minimize default risk and maximize risk-adjusted returns. The strategy is focused on selecting investments that can capture the significant current income and capital appreciation potential of the high yield market while also managing downside risk. The total return sought by the fund consists of income earned on the fund's investments, together with the appreciation that may result from decreases in interest rates or improving credit fundamentals for a particular industry or issuer. The fund may invest significantly in issuers in the communications sector.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal circumstances, the manager invests:&lt;/div&gt;            
            &lt;ul&gt;&lt;li&gt;                  
                  &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Up to 15% of total assets in any one industry; and&lt;/div&gt;               
               &lt;/li&gt;&lt;li&gt;                  
                  &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Up to 5% of total assets in any one issuer (excluding investments in cash-equivalent issuers or for cash-management purposes).&lt;/div&gt;               
               &lt;/li&gt;&lt;/ul&gt;            
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The manager will generally invest in below investment grade debt securities that are rated at least "Caa" by Moody's Investors Service, Inc. or "CCC" by Standard and Poor's Ratings Services, or that are unrated but deemed by the manager to be of comparable quality but may also invest in securities rated below these ratings (or unrated securities of comparable quality). The average credit quality of the fund's securities is expected to be at least B- as rated by Standard and Poor's Ratings Services.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund's investment process may, at times, result in a higher than average portfolio turnover ratio and increased trading expenses.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is subject to risks, and you could lose money by investing in the fund. The principal risks of investing in the fund include:&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Changing distribution levels risk.&lt;/b&gt; The fund may cease or reduce the level of its distribution if income or dividends paid from its investments declines.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security or a borrower of fund securities may not make timely payments or otherwise honor its obligations. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;High portfolio turnover risk.&lt;/b&gt; Trading securities actively and frequently can increase transaction costs (thus lowering performance) and taxable distributions.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Loan participations risk.&lt;/b&gt; Participations and assignments involve special types of risks, including credit risk, interest-rate risk, counterparty risk, liquidity risk, risks associated with extended settlement, and the risks of being a lender.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Technology companies risk.&lt;/b&gt; Technology companies can be significantly affected by rapid obsolescence, short product cycles, competition, and government regulation, among other factors. Investments in the technology sector may be susceptible to heightened risk of cybersecurity breaches, which may allow an unauthorized party to gain access to personally identifiable information and other customer data.&lt;/div&gt;

The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's performance. During its most recent fiscal year, the fund's portfolio turnover rate was 70% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund seeks to generate capital appreciation and income by investing at least 80% of net assets (plus borrowings for investment purposes) in a diversified portfolio of bonds issued by governments, government agencies, international organizations issuing supranational bonds, and corporate issuers in Asia.  Asia means those countries that are located on the Asian continent or are in the Asian region, including Australia and New Zealand. An issuer is considered to be in Asia if its principal place of business is in Asia or it is incorporated or domiciled in Asia or, for supranational issuers, its securities are denominated in Asian currencies.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in fixed-income securities of other issuers outside Asia if the manager considers that such securities may help to achieve the fund's investment objective. The fund may invest in cash and other liquid short-term fixed-income securities when the manager believes that the fund could benefit from maintaining a higher cash exposure, including for temporary defensive purposes.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in investment-grade fixed-income securities and below-investment-grade fixed-income securities (junk bonds). The fund may invest in securities of any maturity, and there is no limit on the maturities of the fixed-income securities in which the fund may invest. There is no limit on the types of issuers in which the fund may invest, which may include issuers of U.S. dollar-denominated securities of foreign governments and corporations, mortgage-related securities, municipal obligations, asset-backed securities, mortgage-backed securities, pay-in-kind bonds, high-yield bonds, emerging-market debt, distressed investments, loan participations, and U.S. TIPS (Treasury Inflation-Protected Securities). The fund may invest in securities with debt/equity characteristics such as preferred shares, convertible bonds, and warrants. The fund may also use derivatives for hedging and efficient portfolio management purposes by utilizing futures, options, options on futures, foreign currency forward contracts, and nondeliverable forwards.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is a non-diversified fund, which means that it may invest in a smaller number of issuers than a diversified fund and may invest more of its assets in the securities of a single issuer.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Asian risk.&lt;/b&gt; Some Asian securities tend to be volatile and may decline in value significantly. Certain companies in Asia may be more vulnerable to political or economic developments or lack access to efficient trading markets. Some Asian countries have restrictions on the extent to which foreigners may invest in their securities markets.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Distressed investments risk.&lt;/b&gt; Distressed investments, including loans, mortgages, bonds, and notes, may not be publicly traded and may involve substantial risk. A fund may lose up to its entire investment.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Greater China risk.&lt;/b&gt; Investments in the Greater China region may be subject to less developed trading markets, acute political risks such as possible negative repercussions resulting from China's relationship with Taiwan or Hong Kong, and restrictions on monetary repatriation or other adverse government actions. For example, a government may restrict investment in companies or industries considered important to national interests, or intervene in the financial markets, such as by imposing trading restrictions, or banning or curtailing short selling. A small number of companies and industries represent a relatively large portion of the Greater China market.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: foreign currency forward contracts, futures contracts, options on futures, and options. Foreign currency forward contracts, futures contracts, and options generally are subject to counterparty risk. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Loan participations risk.&lt;/b&gt; Participations and assignments involve special types of risks, including credit risk, interest-rate risk, counterparty risk, liquidity risk, risks associated with extended settlement, and the risks of being a lender.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Municipal bond risk.&lt;/b&gt; The prices of municipal bonds, including general obligation bonds, can decline if the issuer's credit quality declines. Revenue bond prices can decline if related projects become unprofitable. An insured municipal bond is subject to the risk that the insurer may be unable to pay claims and is not insured with respect to the market value of the obligation. Municipal bond income could become taxable in the future. Investments in AMT bonds may result in tax liability for shareholders.&lt;/div&gt;

Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's performance. During its most recent fiscal year, the fund's portfolio turnover rate was 78% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests primarily in common stocks of established U.S. companies that have above-average potential for capital growth. Common stocks typically constitute at least 50% of the fund's total assets. The remaining assets are generally invested in other securities, including convertible securities, corporate and government debt, bank loans (which represent an interest in amounts owed by a borrower to a syndicate of lenders), foreign securities, futures and options. The fund may invest up to 20% of its total assets in foreign securities.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund's common stocks generally fall into one of two categories: the larger category comprises long-term core holdings whose prices when purchased by the fund are considered low in terms of company assets, earnings, or other factors; the smaller category comprises opportunistic investments whose prices the manager expects to rise in the short term but not necessarily over the long term. There are no limits on the market capitalization of the issuers of the stocks in which the fund invests. Since the manager attempts to prevent losses as well as achieve gains, the manager typically uses a value approach in selecting investments. The manager's in-house research team seeks to identify companies that seem undervalued by various measures, such as price/book value, and may be temporarily out of favor but are believed to have good prospects for capital appreciation. The manager may establish relatively large positions in companies it finds particularly attractive.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;In addition, the manager searches for attractive risk/reward values among all types of securities. The portion of the fund invested in a particular type of security, such as common stocks, results largely from case-by-case investment decisions, and the size of the fund's cash reserve may reflect the manager's ability to find companies that meet valuation criteria rather than its market outlook.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Bonds, bank loans and convertible securities may be purchased to gain additional exposure to a company or for their income or other features; maturity and quality are not necessarily major considerations in determining whether to purchase a particular security. Some loans may be illiquid. The fund's investments in below-investment grade debt securities and loans are limited to 25% of total assets. If a security is split rated (i.e., rated investment grade by at least one rating agency and noninvestment grade by another rating agency), the higher rating will be used for purposes of this requirement. The fund may also purchase other securities, including bank debt, loan participations and assignments and futures and options. The fund's investments in options, if any, will be primarily in an effort to protect against downside risk or to generate additional income.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund holds a certain portion of its assets in money market reserves which can consist of shares of the T. Rowe Price Government Reserve Fund (or any other internal T.

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest up to 10% of its total assets in hybrid instruments to protect against downside risk or as a substitute for investing directly in certain securities. Hybrid instruments are a type of high-risk derivative such as covered calls, over-the-counter options and credit default swaps, which can combine the characteristics of securities, futures and options. Such securities may bear interest or pay dividends at below (or even relatively nominal) rates. In addition, the fund may invest up to 10% of its total assets in mortgage- and asset-backed securities.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may sell securities for a variety of reasons such as to secure gains, limit losses or redeploy assets into more promising opportunities.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is subject to risks, and you could lose money by investing in the fund. The principal risks of investing in the fund include:&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Convertible securities risk.&lt;/b&gt; The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. As the market price of underlying common stock declines below the conversion price, the market value of the convertible security tends to be increasingly influenced by its yield.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: futures contracts, options, and credit default swaps. Futures contracts, options, and credit default swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hybrid instrument risk.&lt;/b&gt; Hybrid instruments entail greater market risk and may be more volatile than traditional debt instruments, may bear interest or pay preferred dividends at below-market rates, and may be illiquid. The risks of investing in hybrid instruments are a combination of the risks of investing in securities, options, futures, and currencies.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Investment company securities risk.&lt;/b&gt; A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Loan participations risk.&lt;/b&gt; Participations and assignments involve special types of risks, including credit risk, interest-rate risk, counterparty risk, liquidity risk, risks associated with extended settlement, and the risks of being a lender.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Value investing style risk.&lt;/b&gt; The fund emphasizes a value style of investing, which focuses on undervalued companies with characteristics for improved valuations. This style of investing is subject to the risk that the valuations never improve or that the returns on value equity securities are less than returns on other styles of investing or the overall stock market. Value stocks also may decline in price, even though in theory they are already underpriced.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's performance. During its most recent fiscal year, the fund's portfolio turnover rate was 46% of the average value of its portfolio.&lt;/div&gt;

    <rr:StrategyNarrativeTextBlock contextRef="c_S000034046_EEEF">         
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in common stocks of companies engaged, at the time of investment, in the research, development, production, or distribution of products or services related to health care, medicine, or the life sciences (collectively termed "health sciences").&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;While the fund may invest in companies of any size, the majority of its assets are expected to be invested in large- and mid-capitalization companies.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The manager's portfolio managers divide the health sciences sector into four main areas: pharmaceutical companies, health care services companies, medical products and devices providers, and biotechnology firms. Their allocation among these four areas will vary depending on the relative potential within each area and the outlook for the overall health sciences sector. While most assets will be invested in U.S. common stocks, the fund may purchase other securities, including foreign securities, futures, and options in keeping with its investment objective. In addition, the fund writes call and put options primarily as a means of generating additional income. The fund reserves the right to use options to seek protection against a decline in the value of its securities or an increase in prices of securities that may be purchased. Normally, the fund will own the securities on which it writes these options. The premium income received by writing covered calls can help reduce but not eliminate portfolio volatility.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund concentrates its investments (invests more than 25% of its total assets) in securities of companies in the health sciences sector, a comparatively narrow segment of the economy, and therefore may experience greater volatility than funds investing in a broader range of industries.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;In managing the fund, the manager uses a fundamental, bottom-up analysis that seeks to identify high quality companies and the most compelling investment opportunities. In general, the fund will follow a growth investment strategy, seeking companies whose earnings are expected to grow faster than inflation and the economy in general. When stock valuations seem unusually high, however, a "value" approach, which gives preference to seemingly undervalued companies, may also be emphasized.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest up to 35% of its total assets in foreign securities (including emerging market securities) and may have exposure to foreign currencies through its investment in these securities, its direct holdings of foreign currencies or through its use of foreign currency exchange contracts for the purchase or sale of a fixed quantity of a foreign currency at a future date.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;In pursuing its investment objective, the fund's management has the discretion to purchase some securities that do not meet its normal investment criteria, as described above, when it perceives an unusual opportunity for gain. These special situations might arise when the fund's management believes a security could increase in value for a variety of reasons including a change in management, an extraordinary corporate event, or a new product introduction or a favorable competitive development.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund holds a certain portion of its assets in money market reserves which can consist of shares of the T. Rowe Price Government Reserve Fund (or any other internal T. Rowe Price money market fund) as well as U.S. dollar and foreign currency-denominated money market securities, including repurchase agreements, in the two highest rating categories, maturing in one year or less.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may sell securities for a variety of reasons such as to secure gains, limit losses or redeploy assets into more promising opportunities.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is subject to risks, and you could lose money by investing in the fund. The principal risks of investing in the fund include:&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Concentration risk.&lt;/b&gt; Because the fund may focus on one or more industries or sectors of the economy, its performance depends in large part on the performance of those sectors or industries. As a result, the value of an investment may fluctuate more widely than it would in a fund that is diversified across industries and sectors.&lt;/div&gt;

               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets.&lt;/div&gt;         
                  
                     
                           
               &lt;div style="font-size:10pt;padding-top:2;padding-bottom:0;padding-left:8;"&gt;                  
                                       
                     &lt;b&gt;Hong Kong Stock Connect Program (Stock Connect) risk&lt;/b&gt;. China A-Shares listed and traded on certain Chinese stock exchanges through Stock Connect, a mutual market access program designed to, among other things, enable foreign investment in the People's Republic of China (PRC) via brokers in Hong Kong, are subject to a number of restrictions imposed by Chinese securities regulations and local exchange listing rules. Because Stock Connect was established in November 2014, developments are likely, which may restrict or otherwise affect the fund's investments or returns. Furthermore, any changes in laws, regulations and policies of the China A-Shares market or rules in relation to Stock Connect may affect China A-Share prices. These risks are heightened by the underdeveloped state of the PRC's investment and banking systems in general.               
               &lt;/div&gt;

               &lt;b&gt;Healthcare sector risk.&lt;/b&gt; Health sciences companies may be significantly affected by product obsolescence, thin capitalization, limited product lines and markets, civil liability claims, and legislative or regulatory activities, among other factors.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: futures contracts and options. Futures contracts and options generally are subject to counterparty risk.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;

               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;

A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's performance. During its most recent fiscal year, the fund's portfolio turnover rate was 41% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund invests primarily in a diversified portfolio of international securities whose issuers are considered by the fund's manager to have potential for earnings or revenue growth. The fund will, under normal circumstances, invest at least 80% of its net assets (plus any borrowings for investment purposes) in stocks. The fund invests primarily in the securities of large-capitalization issuers; however, the fund may invest a significant amount of its net assets in the securities of mid-capitalization issuers.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund invests primarily in equity and depositary receipts of foreign issuers. The principal types of equity securities in which the fund invests are common and preferred stock. The fund invests, under normal circumstances, in issuers economically tied to at least three countries outside of the U.S. The fund may also invest in issuers located in developing countries (emerging markets). Under normal circumstances, the maximum percentage of the fund's net assets that may be invested in these issuers is 1.25 times of the emerging market weight of the MSCI All Country World ex U.S. Growth Index.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund can invest in derivative instruments including forward foreign currency contracts and futures. The fund can utilize forward foreign currency contracts to mitigate the risk of foreign currency exposure. A forward foreign currency contract is an agreement between parties to exchange a specified amount of currency at a specified future time at a specified rate. Forward foreign currency contracts are used to protect against uncertainty in the level of future foreign currency exchange rates. The fund can use these contracts to hedge against adverse movements in the foreign currencies in which portfolio securities are denominated. The fund has the ability to hedge currency exposures created by its investments in foreign securities.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund's portfolio managers may consider selling a security for several reasons, including when (1) its price changes such that they believe it has become too expensive, (2) the original invetment thesis for the company is no longer valid, or (3) a more compeilling investment opportunity is identified.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is subject to risks, and you could lose money by investing in the fund. The principal risks of investing in the fund include:&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
                           
               &lt;div style="font-size:10pt;padding-top:2;padding-bottom:0;padding-left:8;"&gt;                  
                                       
                     &lt;b&gt;Hong&lt;/b&gt;                      
                     &lt;b&gt;Kong Stock Connect Program (Stock Connect) risk&lt;/b&gt;. China A-Shares listed and traded on certain Chinese stock exchanges through Stock Connect, a mutual market access program designed to, among other things, enable foreign investment in the People's Republic of China (PRC) via brokers in Hong Kong, are subject to a number of restrictions imposed by Chinese securities regulations and local exchange listing rules. Because Stock Connect was established in November 2014, developments are likely, which may restrict or otherwise affect the fund's investments or returns. Furthermore, any changes in laws, regulations and policies of the China A-Shares market or rules in relation to Stock Connect may affect China A-Share prices. These risks are heightened by the underdeveloped state of the PRC's investment and banking systems in general.               
               &lt;/div&gt;            
                     
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: foreign currency forward contracts and futures contracts. Foreign currency forward contracts and futures contracts generally are subject to counterparty risk. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mid-sized company risk&lt;/b&gt;. Mid-sized companies are generally less established and may be more volatile than larger companies. Mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred stock risk.&lt;/b&gt; Preferred stock generally ranks senior to common stock with respect to dividends and liquidation but ranks junior to debt securities. Unlike interest payments on debt securities, preferred stock dividends are payable only if declared by the issuer's board of directors. Preferred stock may be subject to optional or mandatory redemption provisions.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;

The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's performance. During its most recent fiscal year, the fund's portfolio turnover rate was 94% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund seeks to achieve its investment objective by investing under normal market conditions at least 80% of its net assets (plus any borrowings for investment purposes) in equity securities of any market capitalization, including futures on indexes of equity securities. The fund primarily invests in foreign securities. The fund's allocation to various markets and types of securities will be actively managed.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in both developed and emerging markets. The fund's investment in equity securities will vary both with respect to types of securities and markets in response to changing market and economic trends. The fund's allocation of securities will depend on the manager's outlook for the markets and generally reflect the manager's strategic asset allocation analysis and their assessment of the relative attractiveness of a particular asset class, country or region. When determining whether to invest in a particular market, the manager considers various factors, including economic and political conditions, potential for economic growth and possible changes in currency exchange rates.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may also invest in equity securities of U.S. issuers. Investments in exchange-traded funds (ETFs) and derivative instruments may be used to reduce risk and/or obtain efficient investment exposure, and may include options, futures contracts, and swaps (including interest-rate swaps).&lt;/div&gt;             
           &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund also may invest in fixed-income securities, including, but not limited to:&lt;/div&gt;            
            &lt;ul&gt;&lt;li&gt;

               &lt;/li&gt;&lt;/ul&gt;            
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The foreign securities in which the fund invests may be denominated in U.S. dollars or foreign currency. The fund may actively manage its exposure to foreign currencies through the use of foreign currency forward contracts and other currency derivatives. The fund may own foreign cash equivalents and foreign bank deposits as part of its investment strategy. The fund may invest in foreign currencies for hedging and speculative purposes. The fund may focus its investments in a particular sector or sectors of the economy.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Use of Hedging and Other Strategic Transactions. The fund is authorized to use all of the various investment strategies referred to under "Principal risks &#8212; Hedging, derivatives and other strategic transactions risk," including, but not limited to, futures and options contracts, foreign currency forward contracts and swaps. The fund may engage in derivatives transactions for hedging and non-hedging purposes including, without limitation, the following purposes:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: foreign currency forward contracts, futures contracts, options, foreign currency swaps, interest-rate swaps and swaps. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;High portfolio turnover risk.&lt;/b&gt; Trading securities actively and frequently can increase transaction costs (thus lowering performance) and taxable distributions.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's performance. During its most recent fiscal year, the fund's portfolio turnover rate was 39% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in companies with market capitalizations that are within the S&amp;amp;P Mid Cap 400 Index ($1.1 billion to $20.1 billion as of October 31, 2018) or the Russell Mid Cap Value Index ($520.3 million to $33.9 billion as of October 31, 2018). The fund invests in a diversified mix of common stocks of mid-size U.S. companies that are believed to be undervalued by various measures and offer good prospects for capital appreciation.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The manager employs a value approach in selecting investments. The manager's in-house research team seeks to identify companies whose stock prices do not appear to reflect their underlying values. The manager generally looks for companies with one or more of the following characteristics:&lt;/div&gt;            
            &lt;ul&gt;&lt;li&gt;                  
                  &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Low stock prices relative to net assets, earnings, cash flow, sales, book value, or private market value;&lt;/div&gt;               
               &lt;/li&gt;&lt;li&gt;                  
                  &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Demonstrated or potentially attractive operating margins, profits and/or cash flow;&lt;/div&gt;               
               &lt;/li&gt;&lt;li&gt;                  
                  &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Sound balance sheets and other positive financial characteristics;&lt;/div&gt;               
               &lt;/li&gt;&lt;li&gt;                  
                  &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Stock ownership by management/employees; and&lt;/div&gt;               
               &lt;/li&gt;&lt;li&gt;                  
                  &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Experienced and capable management.&lt;/div&gt;               
               &lt;/li&gt;&lt;/ul&gt;            
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund's sector exposure is broadly diversified as a result of stock selection and therefore may vary significantly from its benchmark, the Russell Midcap Value Index. The market capitalization of companies held by the fund and included in the indices changes over time. The fund will not automatically sell or cease to purchase stock of a company it already owns just because the company's market capitalization grows or falls outside these ranges.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may sell securities for a variety of reasons, such as to secure gains, limit losses, or redeploy assets into more promising opportunities.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;In pursuing the fund's investment objective, the manager has the discretion to deviate from its normal investment criteria, as described above, and purchase securities that the manager believes will provide an opportunity for substantial appreciation. These situations might arise when the manager believes a security could increase in value for a variety of reasons, including a change in management, an extraordinary corporate event, a new product introduction or innovation, or a favorable competitive development.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in initial public offerings (IPOs). While most assets will be invested in U.S. common stocks, the fund may purchase other types of securities, for example: convertible securities and warrants, foreign securities (up to 20% of total assets), certain exchange-traded funds (ETFs), and certain derivatives (investments whose value is based on indices or other securities). For purposes of the fund, ETFs are considered securities with a market capitalization equal to the weighted average market capitalization of the basket of securities comprising the ETF.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund holds a certain portion of its assets in money market reserves which can consist of shares of the T. Rowe Price Government Reserve Fund (or any other internal T. Rowe Price money market fund) as well as money market securities, including repurchase agreements, in the two highest rating categories, maturing in one year or less.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest up to 10% of its total assets in hybrid instruments. Hybrid instruments are a type of high-risk derivative which can combine the characteristics of securities, futures and options. Such securities may bear interest or pay dividends at below (or even relatively nominal) rates.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Except when engaged in temporary defensive investing, the fund normally has less than 10% of its assets in cash and cash equivalents.  The fund may focus its investments in a particular sector or sectors of the economy.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is subject to risks, and you could lose money by investing in the fund. The principal risks of investing in the fund include:&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Convertible securities risk.&lt;/b&gt; The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. As the market price of underlying common stock declines below the conversion price, the market value of the convertible security tends to be increasingly influenced by its yield.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: futures contracts and options. Futures contracts and options generally are subject to counterparty risk.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hybrid instrument risk.&lt;/b&gt; Hybrid instruments entail greater market risk and may be more volatile than traditional debt instruments, may bear interest or pay preferred dividends at below-market rates, and may be illiquid. The risks of investing in hybrid instruments are a combination of the risks of investing in securities, options, futures, and currencies.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Investment company securities risk.&lt;/b&gt; A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Value investing style risk.&lt;/b&gt; The fund emphasizes a value style of investing, which focuses on undervalued companies with characteristics for improved valuations. This style of investing is subject to the risk that the valuations never improve or that the returns on value equity securities are less than returns on other styles of investing or the overall stock market. Value stocks also may decline in price, even though in theory they are already underpriced.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Warrants risk.&lt;/b&gt; The prices of warrants may not precisely reflect the prices of their underlying securities. Warrant holders do not receive dividends or have voting or credit rights. A warrant ceases to have value if not exercised prior to its expiration date.&lt;/div&gt;

Please see below a hypothetical example showing the expenses of a $10,000 investment for the time periods indicated and then assuming you sell all of your shares at the end of those periods. The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's performance. During its most recent fiscal year, the fund's portfolio turnover rate was 108% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in the common stocks of companies expected to benefit from the development, advancement, and/or use of science and technology. For purposes of satisfying this requirement, common stock may include equity-linked notes and derivatives relating to common stocks, such as options on equity-linked notes.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund employs a multi-manager approach with two managers, each of which employs its own investment approach and independently manages its portion of the fund. The fund will be rebalanced periodically so that the managers manage the following portions of the fund:&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;50%* Allianz Global Investors U.S. LLC ("AllianzGI US")&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;i&gt;*Percentages are approximate. Since the fund is only rebalanced periodically, the actual portion of the fund managed by each manager will vary.&lt;/i&gt;            
            &lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;This allocation methodology may change in the future.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;While most of the fund's assets are invested in U.S. common stocks, the fund may also purchase other types of securities, including U.S. dollar- and foreign currency-denominated foreign securities, convertible stocks and bonds, and warrants, and use futures and options, in keeping with the fund's investment objective.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Stock selection for the fund generally reflects a growth approach based on an assessment of a company's fundamental prospects for above-average earnings, rather than on a company's size. As a result, fund holdings can range from securities of small companies developing new technologies to securities of blue chip firms with established track records. The fund may also invest in companies that are expected to benefit from technological advances even if they are not directly involved in research and development. The fund may invest in technology companies through initial public offerings (IPOs).&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund holds a certain portion of its assets in money market reserves, which can consist of shares of the T. Rowe Price Government Reserve Fund (or any other internal T. Rowe Price money market fund) as well as U.S. dollar- and foreign currency-denominated money market securities, including repurchase agreements, in the two highest rating categories, maturing in one year or less. The fund may invest reserves in U.S. dollars and foreign currencies.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may sell securities for a variety of reasons such as to secure gains, limit losses or redeploy assets into more promising opportunities.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest up to 10% of its total assets in hybrid instruments. Hybrid instruments are a type of high-risk derivative which can combine the characteristics of securities, futures and options. Such securities may bear interest or pay dividends at below market (or even relatively nominal) rates.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;In managing its portion of the fund, AllianzGI US may enter into short sales including short sales against the box.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;In pursuing the fund's investment objective, each manager has the discretion to purchase some securities that do not meet its normal investment criteria, as described above, when they perceive an unusual opportunity for gain. These special situations might arise when a manager believes a security could increase in value for a variety of reasons including a change in management, an extraordinary corporate event, a new product introduction or innovation, or a favorable competitive development.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund's investment process may, at times, result in a higher-than-average portfolio turnover ratio and increased trading expenses.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Convertible securities risk.&lt;/b&gt; The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. As the market price of underlying common stock declines below the conversion price, the market value of the convertible security tends to be increasingly influenced by its yield.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Currency risk.&lt;/b&gt; Fluctuations in exchange rates may adversely affect the U.S. dollar value of a fund's investments. Foreign currencies may decline in value, which could negatively impact performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities.&lt;/div&gt;

China A-Shares listed and traded on certain Chinese stock exchanges through Stock Connect, a mutual market access program designed to, among other things, enable foreign investment in the People's Republic of China (PRC) via brokers in Hong Kong, are subject to a number of restrictions imposed by Chinese securities regulations and local exchange listing rules. Because Stock Connect was established in November 2014, developments are likely, which may restrict or otherwise affect the fund's investments or returns. Furthermore, any changes in laws, regulations and policies of the China A-Shares market or rules in relation to Stock Connect may affect China A-Share prices. These risks are heightened by the underdeveloped state of the PRC's investment and banking systems in general.               
               &lt;/div&gt;

               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: futures contracts, equity-linked notes (equity-linked notes generally reflect the risks associated with their underlying securities, depend on the credit of the note's issuer, may be privately placed, and may have a limited secondary market), and options. Futures contracts and options generally are subject to counterparty risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;High portfolio turnover risk.&lt;/b&gt; Trading securities actively and frequently can increase transaction costs (thus lowering performance) and taxable distributions.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hybrid instrument risk.&lt;/b&gt; Hybrid instruments entail greater market risk and may be more volatile than traditional debt instruments, may bear interest or pay preferred dividends at below-market rates, and may be illiquid. The risks of investing in hybrid instruments are a combination of the risks of investing in securities, options, futures, and currencies.&lt;/div&gt;

               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;

               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Short sales risk.&lt;/b&gt; In a short sale, a fund pays interest on the borrowed security. The fund will lose money if the security price increases between the short sale and the replacement date.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Technology companies risk.&lt;/b&gt; Technology companies can be significantly affected by rapid obsolescence, short product cycles, competition, and government regulation, among other factors. Investments in the technology sector may be susceptible to heightened risk of cybersecurity breaches, which may allow an unauthorized party to gain access to personally identifiable information and other customer data.&lt;/div&gt;

               &lt;b&gt;Warrants risk.&lt;/b&gt; The prices of warrants may not precisely reflect the prices of their underlying securities. Warrant holders do not receive dividends or have voting or credit rights. A warrant ceases to have value if not exercised prior to its expiration date.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;This example is intended to help you compare the cost of investing in the fund with the cost of investing in other mutual funds. Please see below a hypothetical example showing the expenses of a $10,000 investment for the time periods indicated and then assuming you sell all of your shares at the end of those periods. The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's performance. During its most recent fiscal year, the fund's portfolio turnover rate was 20% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund seeks to achieve its investment objective by investing under normal circumstances at least 80% of its net assets (plus borrowings for investment purposes) in obligations issued or guaranteed by the U.S. government and its agencies, authorities or instrumentalities (U.S. government securities). Under normal circumstances, the fund's effective duration is no more than three years.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;U.S. government securities may be supported by:&lt;/div&gt;            
            &lt;ul&gt;&lt;li&gt;                  
                  &lt;div style="font-size:10pt;padding-top:0;padding-bottom:0;padding-left:0;"&gt;The full faith and credit of the United States government, such as Treasury bills, notes and bonds, and Government National Mortgage Association Certificates.&lt;/div&gt;               
               &lt;/li&gt;&lt;li&gt;                  
                  &lt;div style="font-size:10pt;padding-top:0;padding-bottom:0;padding-left:0;"&gt;The right of the issuer to borrow from the U.S. Treasury, such as obligations of the Federal Home Loan Mortgage Corporation.&lt;/div&gt;               
               &lt;/li&gt;&lt;li&gt;                  
                  &lt;div style="font-size:10pt;padding-top:0;padding-bottom:0;padding-left:0;"&gt;The credit of the instrumentality, such as for obligations of the Federal National Mortgage Association.&lt;/div&gt;               
               &lt;/li&gt;&lt;/ul&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in higher-risk securities, including U.S. dollar-denominated foreign government securities and asset-backed securities. It may also invest up to 10% of its net assets in foreign governmental high yield securities (junk bonds) rated as low as B and their unrated equivalents. The fund's investment policies are based on credit ratings at the time of purchase.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;In managing the portfolio of the fund, the manager considers interest rate trends to determine which types of bonds to emphasize at a given time. The fund typically favors mortgage-related securities when it anticipates that interest rates will be relatively stable, and favors U.S. Treasuries at other times. Because high yield bonds often respond to market movements differently from U.S. government bonds, the fund may use them to manage volatility.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in mortgage-related securities and Treasury futures to protect against adverse changes and manage risks.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in other investment companies, including exchange traded funds ("ETFs"), and engage in short sales.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal circumstances, the fund's effective duration is no more than three years, which means that the fund may purchase securities with a duration of greater than three years as long as the fund's average duration does not exceed three years.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may trade securities actively which could increase transaction costs (thus lowering performance).&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is subject to risks, and you could lose money by investing in the fund. The principal risks of investing in the fund include:&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Changing distribution levels risk.&lt;/b&gt; The fund may cease or reduce the level of its distribution if income or dividends paid from its investments declines.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;High portfolio turnover risk.&lt;/b&gt; Trading securities actively and frequently can increase transaction costs (thus lowering performance) and taxable distributions.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Investment company securities risk.&lt;/b&gt; A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Short sales risk.&lt;/b&gt; In a short sale, a fund pays interest on the borrowed security. The fund will lose money if the security price increases between the short sale and the replacement date.&lt;/div&gt;

The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's performance. During its most recent fiscal year, the fund's portfolio turnover rate was 92% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in stocks of small-cap companies. For the purposes of the fund, "small cap companies" are those with market capitalizations, at the time of investment, not exceeding the maximum market capitalization of any company represented in either the Russell 2000 Index (approximately $6.3 billion as of October 31, 2018) or the S&amp;amp;P SmallCap 600 Index (approximately $4.7 billion as of October 31, 2018).&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund invests in small-cap companies that are believed to offer above-average potential for growth in revenues and earnings. Market capitalizations of companies in the indices change over time; however, the fund will not sell a security just because a company has grown to a market capitalization outside the maximum range of the indices.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The manager selects stocks using a combination of quantitative screens and bottom-up, fundamental security research. Quantitative screening seeks to narrow the list of small capitalization companies and to identify a group of companies with strong revenue growth and accelerating earnings. Fundamental equity research seeks to identify individual companies from that group with a higher potential for earnings growth and capital appreciation.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The manager looks for companies based on a combination of criteria including one or more of the following:&lt;/div&gt;            
            &lt;ul&gt;&lt;li&gt;                  
                  &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Improving market shares and positive financial trends;&lt;/div&gt;               
               &lt;/li&gt;&lt;li&gt;                  
                  &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Superior management with significant equity ownership; and&lt;/div&gt;               
               &lt;/li&gt;&lt;li&gt;                  
                  &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Attractive valuations relative to earnings growth outlook.&lt;/div&gt;               
               &lt;/li&gt;&lt;/ul&gt;           
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is likely to experience periods of higher turnover in portfolio securities because the manager frequently adjusts the selection of companies and/or their position size based on these criteria. The fund's sector exposures are broadly diversified, but are primarily a result of stock selection and therefore may vary significantly from its benchmark. The fund may invest up to 25% of its total assets in foreign securities, including emerging market securities. The fund may invest significantly in the information technology sector.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Except as otherwise stated under "Additional information about the funds," the fund normally has 10% or less (usually lower) of its total assets in cash and cash equivalents.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in initial public offerings (IPOs). The fund may also purchase each of the following types of securities: U.S. dollar-denominated foreign securities and certain exchange-traded funds (ETFs).&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is subject to risks, and you could lose money by investing in the fund. The principal risks of investing in the fund include:&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;

               &lt;b&gt;Equity securities risk.&lt;/b&gt; The value of a company's equity securities is subject to changes in the company's financial condition, and overall market and economic conditions. Investments in the stocks of privately held companies and newly public companies involve greater risks than investments in stocks of companies that have traded publicly on an exchange for extended time periods. Investments in such companies are less liquid and difficult to value, and there is significantly less information available about these companies' business models, quality of management, earnings growth potential, and other criteria used to evaluate their investment prospects.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;High portfolio turnover risk.&lt;/b&gt; Trading securities actively and frequently can increase transaction costs (thus lowering performance) and taxable distributions.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Information technology risk.&lt;/b&gt; Information technology companies can be significantly affected by rapid obsolescence, short product cycles, competition, and government regulation, among other factors.

A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's performance. During its most recent fiscal year, the fund's portfolio turnover rate was 25% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in small-cap companies that are believed to be undervalued by various measures and offer good prospects for capital appreciation. The fund defines small-cap companies as those with market capitalizations at or below the market capitalization of the largest company represented in either the Russell 2000 Value Index (approximately $5.4 billion as of October 31, 2018) or the S&amp;amp;P SmallCap 600 Index (approximately $4.4 billion as of October 31, 2018).&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund invests primarily in a diversified mix of common stocks of U.S. small-cap companies. The manager employs a value-oriented investment approach in selecting stocks, using proprietary fundamental research to identify stocks the manager believes have distinct value characteristics based on industry-specific valuation criteria. The manager focuses on high-quality companies with a proven record of above-average rates of profitability that sell at a discount relative to the overall small-cap market.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The manager seeks to identify companies demonstrating one or more of the following characteristics: sustainable competitive advantages within a market niche; strong profitability and free cash flows; strong market share positions and trends; quality of and share ownership by management; and conservative financial structures relative to industry average.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund's sector exposures are broadly diversified but may vary significantly from the fund's benchmark. The fund may invest up to 15% of its total assets in foreign securities (including up to 5% in emerging-market securities). The fund may invest significantly in financial services companies.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal circumstances, the fund invests 10% or less (usually less) of its total assets in cash and cash equivalents.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in initial public offerings (IPOs). The fund may also purchase real estate investment trusts (REITs) or other real estate related equity securities, U.S. dollar-denominated foreign securities, and certain exchange-traded funds (ETFs). ETFs are considered securities with a market capitalization equal to the weighted average market capitalization of the basket of securities that compose the ETF. The fund may focus its investments in a particular sector or sectors of the economy.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is subject to risks, and you could lose money by investing in the fund. The principal risks of investing in the fund include:&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Financial services sector risk.&lt;/b&gt; Financial services companies can be significantly affected by economic, market, and business developments, borrowing costs, interest-rate fluctuations, competition, and government regulation, among other factors.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Real estate investment trust risk.&lt;/b&gt; REITs, pooled investment vehicles that typically invest in real estate directly or in loans collateralized by real estate, carry risks associated with owning real estate, including the potential for a decline in value due to economic or market conditions.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Real estate securities risk.&lt;/b&gt; Securities of companies in the real estate industry carry risks associated with owning real estate, including the potential for a decline in value due to economic or market conditions.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

               &lt;b&gt;Value investing style risk.&lt;/b&gt; The fund emphasizes a value style of investing, which focuses on undervalued companies with characteristics for improved valuations. This style of investing is subject to the risk that the valuations never improve or that the returns on value equity securities are less than returns on other styles of investing or the overall stock market. Value stocks also may decline in price, even though in theory they are already underpriced.&lt;/div&gt;

The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's performance. During its most recent fiscal year, the fund's portfolio turnover rate was 115% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund seeks to achieve its investment objective by investing under normal market conditions at least 80% of its net assets (plus any borrowings for investment purposes) in U.S. and foreign equity securities of any market capitalization, including futures on indexes of equity securities. The fund's allocation to various markets and types of securities will be actively managed.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in both developed and emerging markets. The fund's investment in equity securities will vary both with respect to types of securities and markets in response to changing market and economic trends. The fund's allocation of securities will depend on the manager's outlook for the markets and generally reflect the manager's strategic asset allocation analysis and their assessment of the relative attractiveness of a particular asset class. When determining whether to invest in a particular market, the manager considers various factors, including economic and political conditions, potential for economic growth and possible changes in currency exchange rates.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund also may invest in exchange-traded funds and in fixed-income securities, including, but not limited to:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The foreign securities in which the fund invests may be denominated in U.S. dollars or foreign currency.

The fund may engage in derivatives transactions for hedging and non-hedging purposes including, without limitation, the following purposes:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is subject to risks, and you could lose money by investing in the fund. The principal risks of investing in the fund include:&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, options, swaps, and total return swaps. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;High portfolio turnover risk.&lt;/b&gt; Trading securities actively and frequently can increase transaction costs (thus lowering performance) and taxable distributions.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance.

Past performance (before and after taxes) does not indicate future results. The fund's custom blended benchmark comprises 70% Russell 3000 Index/30% MSCI ACWI ex-USA Index and shows how the fund's performance compares against the returns of similar investments.

A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's performance. During its most recent fiscal year, the fund's portfolio turnover rate was 63% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests at least 80% of its assets in the following types of securities, which may be denominated in U.S. dollars or foreign currencies: foreign government and corporate debt securities from developed and emerging markets, U.S. government and agency securities, domestic high-yield bonds, and investment-grade corporate bonds and currency instruments. The fund may also invest in preferred stock and other types of debt securities, including mortgage-and asset-backed securities and loans. Some loans may be illiquid. No more than 80% of the fund's assets will consist of instruments denominated in foreign currencies.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Although the fund may invest up to 10% of its total assets in securities rated as low as D (in default) by Standard &amp;amp; Poor's Ratings Services (S&amp;amp;P) or Moody's Investors Service, Inc. (Moody's), or their unrated equivalents, it generally intends to keep its average credit quality in the investment-grade range (i.e., AAA to BBB). Bonds that are rated at or below BB by S&amp;amp;P or Ba by Moody's are considered junk bonds. There is no limit on the average maturity of the fund's portfolio. The fund's investment policies are based on credit ratings at the time of purchase. Under normal circumstances, the fund may invest up to 15% of total assets in asset-backed securities rated lower than A by S&amp;amp;P or Moody's, or their unrated equivalents (but under no circumstances lower than B or their unrated equivalents).&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;In managing the fund, the manager allocates assets among the four major types of instruments noted above based on analysis of global economic factors such as fiscal and monetary policies, projected international interest-rate movements, political environments, and currency trends. In abnormal circumstances, the manager may invest up to 100% of the fund's assets in any one sector. The manager looks for investments that are appropriate for the fund in terms of yield, credit quality, structure, and industry distribution. Relative yields and risk/reward ratios are the primary considerations in selecting securities.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may use certain higher-risk investments, including derivatives such as futures, options, and swaps (including credit default swaps), as well as restricted or illiquid securities. The fund may also invest significantly in currency spots and forwards, currency futures and options, and interest-rate options for both hedging and nonhedging purposes, including for purposes of enhancing returns. In addition, the fund may invest up to 10% of its net assets in domestic or foreign common stocks.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may trade securities actively and its investment process may, at times, result in a higher-than-average portfolio turnover ratio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is subject to risks, and you could lose money by investing in the fund. The principal risks of investing in the fund include:&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Asset-backed securities risk.&lt;/b&gt; Asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Changing distribution levels risk.&lt;/b&gt; The fund may cease or reduce the level of its distribution if income or dividends paid from its investments declines.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Currency risk.&lt;/b&gt; Fluctuations in exchange rates may adversely affect the U.S. dollar value of a fund's investments. Foreign currencies may decline in value, which could negatively impact performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Defaulted debt risk.&lt;/b&gt; Investing in defaulted debt securities is speculative and involves substantial risks in addition to those of non-defaulted high-yield securities. Defaulted debt securities generally do not generate interest payments. Principal on defaulted debt might not be repaid, and a fund could lose up to its entire investment.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, options, and swaps. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;High portfolio turnover risk.&lt;/b&gt; Trading securities actively and frequently can increase transaction costs (thus lowering performance) and taxable distributions.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;

Please see below a hypothetical example showing the expenses of a $10,000 investment for the time periods indicated and then assuming you sell all of your shares at the end of those periods. The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's performance. During its most recent fiscal year, the fund's portfolio turnover rate was 34% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests at least 65% of its net assets in a diversified portfolio of fixed-income instruments of varying maturities, which may be represented by forwards or derivatives, such as options, futures contracts, or swap agreements.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;In selecting securities for the fund, the manager utilizes economic forecasting, interest rate anticipation, credit and call risk analysis, foreign currency exchange rate forecasting, and other security selection techniques. The proportion of the fund's assets committed to investment in securities with particular characteristics (such as maturity, type and coupon rate) will vary based on the manager's outlook for the U.S. and foreign economies, the financial markets, and other factors.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The types of fixed-income securities in which the fund may invest include the following securities which, unless otherwise noted, may be issued by domestic or foreign issuers and may be denominated in U.S. dollars or foreign currencies:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Fixed-income securities may have fixed, variable, or floating rates of interest, including rates of interest that vary inversely at a multiple of a designated or floating rate, or that vary according to change in relative values of currencies.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund invests primarily in investment-grade securities, but may invest up to 10% of its total assets in high yield securities ("junk bonds") rated B or higher by Moody's Investors Service, Inc. or equivalently rated by Standard and Poor's Ratings Services or Fitch Ratings Inc., or, if unrated, determined by the manager to be of comparable quality (except that within such limitations, the fund may invest in mortgage-related securities and variable rate master demand notes rated below B). The fund may also invest up to 30% of its total assets in securities denominated in foreign currencies, and may invest beyond this limit in U.S. dollar-denominated securities of foreign issuers. The fund may invest in baskets of foreign currencies (such as the euro) and direct currency. The fund will normally limit its foreign currency exposure (from foreign-currency denominated securities or currencies) to 20% of its total assets. The fund may invest up to 15% of its total assets in securities and instruments that are economically tied to emerging market countries. This limitation does not apply to investment grade sovereign debt denominated in the local currency with less than one year remaining to maturity. The fund's investment policies are based on credit ratings at the time of purchase.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest up to 10% of its total assets in preferred stocks, convertible securities, and other equity related securities.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The average portfolio duration of the fund normally varies within two years (plus or minus) of the duration of the benchmark index, as calculated by the manager.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund's investment process may, at times, result in a higher than average portfolio turnover ratio and increased trading expenses.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may make short sales of a security, including short sales "against the box."&lt;/div&gt;

               &lt;b&gt;Currency risk.&lt;/b&gt; Fluctuations in exchange rates may adversely affect the U.S. dollar value of a fund's investments. Foreign currencies may decline in value, which could negatively impact performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, foreign currency swaps, futures contracts, inverse floating-rate securities, interest rate swaps, total return swaps, reverse repurchase agreements, swaps and options. Foreign currency forward contracts, futures contracts, options on futures, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk. An event of default or insolvency of the counterparty to a reverse repurchase agreement could result in delays or restrictions with respect to the fund's ability to dispose of the underlying securities. In addition, a reverse repurchase agreement may be considered a form of leverage and may, therefore, increase fluctuations in the fund's net asset value per share.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;High portfolio turnover risk.&lt;/b&gt; Trading securities actively and frequently can increase transaction costs (thus lowering performance) and taxable distributions.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hybrid instrument risk.&lt;/b&gt; Hybrid instruments entail greater market risk and may be more volatile than traditional debt instruments, may bear interest or pay preferred dividends at below-market rates, and may be illiquid. The risks of investing in hybrid instruments are a combination of the risks of investing in securities, options, futures, and currencies.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Loan participations risk.&lt;/b&gt; Participations and assignments involve special types of risks, including credit risk, interest-rate risk, counterparty risk, liquidity risk, risks associated with extended settlement, and the risks of being a lender.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Municipal bond risk.&lt;/b&gt; The prices of municipal bonds, including general obligation bonds, can decline if the issuer's credit quality declines. Revenue bond prices can decline if related projects become unprofitable. An insured municipal bond is subject to the risk that the insurer may be unable to pay claims and is not insured with respect to the market value of the obligation. Municipal bond income could become taxable in the future. Investments in AMT bonds may result in tax liability for shareholders.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Short sales risk.&lt;/b&gt; In a short sale, a fund pays interest on the borrowed security. The fund will lose money if the security price increases between the short sale and the replacement date.&lt;/div&gt;

Please see below a hypothetical example showing the expenses of a $10,000 investment for the time periods indicated and then assuming you sell all of your shares at the end of those periods. The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's performance. During its most recent fiscal year, the fund's portfolio turnover rate was 128% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund seeks to achieve its investment objective by investing under normal market conditions at least 80% of its net assets (plus any borrowings for investment purposes) in U.S. equity securities of any market capitalization, including futures on indexes of equity securities. The fund defines U.S. equity securities as: (i) securities of issuers that are organized under the laws of the United States or that maintain their principal place of business in the United States; (ii) securities of issuers that are traded principally in the United States; or (iii) securities of issuers that, during the most recent fiscal year, derived at least 50% of their revenues or profits from goods produced or sold, investments made, or services performed in the United States or that have at least 50% of their assets in the United States. The fund's allocation to various markets and types of securities will be actively managed.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund's investment in equity securities will vary both with respect to types of securities and markets in response to changing market and economic trends. The fund's allocation of securities will depend on the manager's outlook for the markets and generally reflect the manager's strategic asset allocation analysis and their assessment of the relative attractiveness of a particular asset class. When determining whether to invest in a particular market capitalization, sector or industry, the manager takes into consideration a variety of inputs including economic, fundamental (valuations and earnings), and technical indicators, among other factors.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest up to 20% of its net assets in equity securities of foreign issuers. Investments in exchange-traded funds (ETFs) and derivative instruments may be used to reduce risk and/or obtain efficient investment exposure, and may include options, futures contracts, and swaps (including interest-rate swaps).&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund also may invest in fixed-income securities, including, but not limited to:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The foreign securities in which the fund invests may be denominated in U.S. dollars or foreign currency. The fund may actively manage its exposure to foreign currencies through the use of foreign currency forward contracts and other currency derivatives. The fund may own foreign cash equivalents and foreign bank deposits as part of its investment strategy. The fund may invest in foreign currencies for hedging and speculative purposes. The fund may focus its investments in a particular sector or sectors of the economy.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Use of Hedging and Other Strategic Transactions. The fund is authorized to use all of the various investment strategies referred to under "Principal risks &#8212; Hedging, derivatives and other strategic transactions risk," including, but not limited to, futures and options contracts, foreign currency forward contracts and swaps. The fund may engage in derivatives transactions for hedging and non-hedging purposes including, without limitation, the following purposes:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: foreign currency forward contracts, futures contracts, options, foreign currency swaps, interest-rate swaps and swaps. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;High portfolio turnover risk.&lt;/b&gt; Trading securities actively and frequently can increase transaction costs (thus lowering performance) and taxable distributions.&lt;/div&gt;

               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;

               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;

               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;

               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;

               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;

The example assumes a 5% average annual return and that fund expenses will not change over the periods.

A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's performance. During its most recent fiscal year, the fund's portfolio turnover rate was 74% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in equity investments that are tied economically to the United States. The fund considers an equity investment to be "tied economically" to the United States if, at the time of purchase: (i) its issuer is organized under the laws of the United States or under the laws of a state within the United States or in an issuer that maintains its principal place of business in the United States; (ii) it is traded principally in the United States; or (iii) its issuer derived at least 50% of its revenues or profits from goods produced or sold, investments made, or services performed in the United States, or has at least 50% of its assets in the United States. The manager seeks to achieve the fund's investment objective by investing in equity investments that the manager believes, as a portfolio, will provide higher returns than the Russell 1000 Growth Index.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The manager's investment process begins with the broad universe of equity securities included in US equity indices, along with other ideas that come from a combination of company meetings, investment conferences, field trips and industry analysis. Investments in equity securities include common stocks and other stock-related securities such as preferred stocks, convertible securities, depositary receipts, exchange-traded funds, and exchange-traded equity real estate investment trusts (REITs). The fund may invest significantly in securities of companies in certain sectors, and may therefore experience greater volatility than funds investing in a broader range of sectors and may be more susceptible to the impact of market, economic, regulatory, and other factors affecting that sector.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The manager focuses on members of the investable universe with expected future free cash-flow margins, returns on capital employed and revenue growth higher than a certain minimum threshold. The manager then monitors and ranks securities based on their relative attractiveness across this universe, based on quality, growth, valuation, capital returns, and earnings outlook. For stocks that compare well in this screening process, further detailed analysis is conducted. Regular meetings and discussions with company management are another input into the portfolio decision making process.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Securities considered for purchase are attractive on a majority of the metrics (quality, growth, valuation, capital returns, and earnings outlook), and have a positive catalyst such as accelerating earnings or revenue growth. Due to its active investment strategy, the fund may buy and sell securities frequently. This may result in higher transaction costs and more capital gains tax liabilities than a fund with a buy and hold strategy.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The following information illustrates the variability of the fund's returns and provides some indication of the risks of investing in the fund by showing changes in the fund's performance from year to year and by showing how the fund's average annual returns compared with a broad-based market index. Past performance (before and after taxes) does not indicate future results. The Bloomberg Barclays U.S. High Yield 2% Issuer Capped Index shows how the fund's performance compares against the returns of similar investments. All figures assume dividend reinvestment. Performance information is updated daily, monthly, and quarterly and may be obtained at our website, jhinvestments.com, or by calling 800-344-1029 between 8:00 A.M. and 7:00 P.M., Eastern time, on most business days.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Class NAV and Class 1 shares commenced operations on October 29, 2005 and May 7, 2012, respectively. Returns for Class 1 shares prior to May 7, 2012 are those of Class NAV shares. Returns for Class 1 shares would have been substantially similar to returns of Class NAV shares because both share classes are invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Prior to September 29, 2016, the fund was managed by a different subadvisor pursuant to a different investment strategy, and thus, the performance presented prior to this date should not be attributed to the current subadvisor. As a result of the difference in investment strategy and subadvisor, the fund's performance shown below might have differed materially.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Please note that after-tax returns reflect the highest individual federal marginal income-tax rate in effect as of the date provided and do not reflect any state or local taxes. Your actual after-tax returns may be different. After-tax returns are not relevant to shares held in an IRA, 401(k), or other tax-advantaged investment plan.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is subject to risks, and you could lose money by investing in the fund. The principal risks of investing in the fund include:&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;High portfolio turnover risk.&lt;/b&gt; Trading securities actively and frequently can increase transaction costs (thus lowering performance) and taxable distributions.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Real estate investment trust risk.&lt;/b&gt; REITs, pooled investment vehicles that typically invest in real estate directly or in loans collateralized by real estate, carry risks associated with owning real estate, including the potential for a decline in value due to economic or market conditions.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Real estate securities risk.&lt;/b&gt; Securities of companies in the real estate industry carry risks associated with owning real estate, including the potential for a decline in value due to economic or market conditions.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 15% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund operates as a fund of funds and, except as otherwise described below, normally invests approximately 100% of its assets in underlying funds that invest primarily in equity securities. Underlying funds may be affiliated or unaffiliated and may include exchange-traded funds (ETFs).&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Variations in the target percentage allocation between underlying funds that invest primarily in equity securities and underlying funds that invest primarily in fixed-income securities are permitted up to 10%. There is no limit on the range of maturities and credit quality of securities in which the fund and underlying funds may invest. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from short to longer term. The fixed-income underlying funds collectively hold various types of debt instruments, such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging-market securities). The portfolio managers may exceed the normal percentage limitations to protect the fund or seek to achieve its goal in light of market or economic conditions.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in various passively managed underlying funds that, as a group, hold a wide range of equity-type securities. The fund may also invest in various actively managed underlying funds. The fund is not designed to track an index or group of indexes. Equity-type securities include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. Each of the underlying funds has its own investment strategy that, for example, may focus on growth stocks, value stocks, or a combination of growth and income stocks. Underlying funds may invest in derivatives such as options on securities and futures contracts.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may also invest in derivatives such as credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, as well as in exchange-traded notes (ETNs). The fund may also purchase futures contracts for cash management purposes and to gain investment exposure pending investments.). The fund is also authorized to use various other investment strategies such as investing directly in fixed-income and equity securities, including U.S. government securities, mortgage-backed and asset-backed securities, closed-end funds, and partnerships. The fund may also short-sell securities.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The investment performance of each fund will reflect both its managers' allocation decisions with respect to the underlying funds and the investment decisions made by the underlying funds' managers.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in equity securities than John Hancock Multi-Index Lifestyle Portfolios with greater target allocations to underlying funds that invest primarily in fixed-income securities, equity security risks are more prevalent in this fund than in other, John Hancock Multi-Index Lifestyle Portfolios. In addition to equity securities risk, the fund's other main risk factors are listed in alphabetical order.&lt;/div&gt;          
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                 &lt;i&gt; Principal risks of investing in the fund of funds  &lt;/i&gt;             
               &lt;/b&gt;&lt;/div&gt;             
                     
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions.&lt;/div&gt;

               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Investment company securities risk.&lt;/b&gt; A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Short sales risk.&lt;/b&gt; In a short sale, a fund pays interest on the borrowed security. The fund will lose money if the security price increases between the short sale and the replacement date.&lt;/div&gt;         
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                &lt;i&gt;  Principal risks of investing in the underlying funds  &lt;/i&gt;             
               &lt;/b&gt;&lt;/div&gt;             
                     
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;

               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

Please see below a hypothetical example showing the expenses of a $10,000 investment for the time periods indicated and then assuming you sell all of your shares at the end of those periods. The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 17% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund operates as a fund of funds and, except as otherwise described below, normally invests approximately 40% of its assets in underlying funds that invest primarily in fixed-income securities and approximately 60% of its assets in underlying funds that invest primarily in equity securities. Underlying funds may be affiliated or unaffiliated and may include exchange-traded funds (ETFs).&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Variations in the target percentage allocation between underlying funds that invest primarily in equity securities and underlying funds that invest primarily in fixed-income securities are permitted up to 10%. There is no limit on the range of maturities and credit quality of securities in which the fund and underlying funds may invest. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from short to longer term. The fixed-income underlying funds collectively hold various types of debt instruments, such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging-market securities). The portfolio managers may exceed the normal percentage limitations to protect the fund or seek to achieve its goal in light of market or economic conditions.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in various passively managed underlying funds that, as a group, hold a wide range of equity-type securities. The fund may also invest in various actively managed underlying funds. The fund is not designed to track an index or group of indexes. Equity-type securities include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. Each of the underlying funds has its own investment strategy that, for example, may focus on growth stocks, value stocks, or a combination of growth and income stocks. Underlying funds may invest in derivatives such as options on securities and futures contracts.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may also invest in derivatives such as credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, as well as in exchange-traded notes (ETNs). The fund may also purchase futures contracts for cash management purposes and to gain investment exposure pending investments.). The fund is also authorized to use various other investment strategies such as investing directly in fixed-income and equity securities, including U.S. government securities, mortgage-backed and asset-backed securities, closed-end funds, and partnerships. The fund may also short-sell securities.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The investment performance of each fund will reflect both its managers' allocation decisions with respect to the underlying funds and the investment decisions made by the underlying funds' managers.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in equity securities than John Hancock Multi-Index Lifestyle Portfolios with greater target allocations to underlying funds that invest primarily in fixed-income securities, equity security risks are more prevalent in this fund than in other, John Hancock Multi-Index Lifestyle Portfolios. In addition to equity securities risk, the fund's other main risk factors are listed in alphabetical order.&lt;/div&gt;

               &lt;/b&gt;&lt;/div&gt;             
                     
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions.&lt;/div&gt;

               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Investment company securities risk.&lt;/b&gt; A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Short sales risk.&lt;/b&gt; In a short sale, a fund pays interest on the borrowed security. The fund will lose money if the security price increases between the short sale and the replacement date.&lt;/div&gt;         
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
               &lt;i&gt;   Principal risks of investing in the underlying funds   &lt;/i&gt;            
               &lt;/b&gt;&lt;/div&gt;             
                     
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;

               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;

               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

Please see below a hypothetical example showing the expenses of a $10,000 investment for the time periods indicated and then assuming you sell all of your shares at the end of those periods. The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 24% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund operates as a fund of funds and, except as otherwise described below, normally invests approximately 80% of its assets in underlying funds that invest primarily in fixed-income securities and approximately 20% in underlying funds that invest primarily in equity securities. Underlying funds may be affiliated or unaffiliated and may include exchange-traded funds (ETFs).&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Variations in the target percentage allocation between underlying funds that invest primarily in equity securities and underlying funds that invest primarily in fixed-income securities are permitted up to 10%. There is no limit on the range of maturities and credit quality of securities in which the fund and underlying funds may invest. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from short to longer term. The fixed-income underlying funds collectively hold various types of debt instruments, such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging-market securities). The portfolio managers may exceed the normal percentage limitations to protect the fund or seek to achieve its goal in light of market or economic conditions.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in various passively managed underlying funds that, as a group, hold a wide range of equity-type securities. The fund may also invest in various actively managed underlying funds. The fund is not designed to track an index or group of indexes. Equity-type securities include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. Each of the underlying funds has its own investment strategy that, for example, may focus on growth stocks, value stocks, or a combination of growth and income stocks. Underlying funds may invest in derivatives such as options on securities and futures contracts.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may also invest in derivatives such as credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, as well as in exchange-traded notes (ETNs). The fund may also purchase futures contracts for cash management purposes and to gain investment exposure pending investments.). The fund is also authorized to use various other investment strategies such as investing directly in fixed-income and equity securities, including U.S. government securities, mortgage-backed and asset-backed securities, closed-end funds, and partnerships. The fund may also short-sell securities.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The investment performance of each fund will reflect both its managers' allocation decisions with respect to the underlying funds and the investment decisions made by the underlying funds' managers.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in fixed-income securities than John Hancock Multi-Index Lifestyle Portfolios with greater target allocations to underlying funds that invest primarily in equity securities, fixed-income security risks are more prevalent in this fund than in other, John Hancock Multi-Index Lifestyle  Portfolios. In addition to fixed-income securities risk, the fund's other main risk factors are listed below in alphabetical order.&lt;/div&gt;

               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;

               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;

               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions.&lt;/div&gt;

               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;

               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Investment company securities risk.&lt;/b&gt; A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Short sales risk.&lt;/b&gt; In a short sale, a fund pays interest on the borrowed security. The fund will lose money if the security price increases between the short sale and the replacement date.&lt;/div&gt;

Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

Please see below a hypothetical example showing the expenses of a $10,000 investment for the time periods indicated and then assuming you sell all of your shares at the end of those periods. The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 16% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund operates as a fund of funds and, except as otherwise described below, normally invests approximately 20% of its assets in underlying funds that invest primarily in fixed-income securities and approximately 80% of its assets in underlying funds that invest primarily in equity securities. Underlying funds may be affiliated or unaffiliated and may include exchange-traded funds (ETFs).&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Variations in the target percentage allocation between underlying funds that invest primarily in equity securities and underlying funds that invest primarily in fixed-income securities are permitted up to 10%. There is no limit on the range of maturities and credit quality of securities in which the fund and underlying funds may invest. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from short to longer term. The fixed-income underlying funds collectively hold various types of debt instruments, such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging-market securities). The portfolio managers may exceed the normal percentage limitations to protect the fund or seek to achieve its goal in light of market or economic conditions.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in various passively managed underlying funds that, as a group, hold a wide range of equity-type securities. The fund may also invest in various actively managed underlying funds. The fund is not designed to track an index or group of indexes. Equity-type securities include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. Each of the underlying funds has its own investment strategy that, for example, may focus on growth stocks, value stocks, or a combination of growth and income stocks. Underlying funds may invest in derivatives such as options on securities and futures contracts.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may also invest in derivatives such as credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, as well as in exchange-traded notes (ETNs). The fund may also purchase futures contracts for cash management purposes and to gain investment exposure pending investments.). The fund is also authorized to use various other investment strategies such as investing directly in fixed-income and equity securities, including U.S. government securities, mortgage-backed and asset-backed securities, closed-end funds, and partnerships. The fund may also short-sell securities.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The investment performance of each fund will reflect both its managers' allocation decisions with respect to the underlying funds and the investment decisions made by the underlying funds' managers.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in equity securities than John Hancock Multi-Index Lifestyle Portfolios with greater target allocations to underlying funds that invest primarily in fixed-income securities, equity security risks are more prevalent in this fund than in other, John Hancock Multi-Index Lifestyle Portfolios. In addition to equity securities risk, the fund's other main risk factors are listed in alphabetical order.&lt;/div&gt;

               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;

               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions.&lt;/div&gt;

               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;

               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;

               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Investment company securities risk.&lt;/b&gt; A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Short sales risk.&lt;/b&gt; In a short sale, a fund pays interest on the borrowed security. The fund will lose money if the security price increases between the short sale and the replacement date.&lt;/div&gt;

               &lt;i&gt;   Principal risks of investing in the underlying funds   &lt;/i&gt;            
               &lt;/b&gt;&lt;/div&gt;             
                     
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;

               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;This example is intended to help you compare the cost of investing in the fund with the cost of investing in other mutual funds. Please see below a hypothetical example showing the expenses of a $10,000 investment for the time periods indicated and then assuming you sell all of your shares at the end of those periods. The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 20% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund operates as a fund of funds and, except as otherwise described below, normally invests approximately 60% of its assets in underlying funds that invest primarily in fixed-income securities and approximately 40% in underlying funds that invest primarily in equity securities. Underlying funds may be affiliated or unaffiliated and may include exchange-traded funds (ETFs).&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Variations in the target percentage allocation between underlying funds that invest primarily in equity securities and underlying funds that invest primarily in fixed-income securities are permitted up to 10%. There is no limit on the range of maturities and credit quality of securities in which the fund and underlying funds may invest. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from short to longer term. The fixed-income underlying funds collectively hold various types of debt instruments, such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging-market securities). The portfolio managers may exceed the normal percentage limitations to protect the fund or seek to achieve its goal in light of market or economic conditions.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in various passively managed underlying funds that, as a group, hold a wide range of equity-type securities. The fund may also invest in various actively managed underlying funds. The fund is not designed to track an index or group of indexes. Equity-type securities include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. Each of the underlying funds has its own investment strategy that, for example, may focus on growth stocks, value stocks, or a combination of growth and income stocks. Underlying funds may invest in derivatives such as options on securities and futures contracts.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may also invest in derivatives such as credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, as well as in exchange-traded notes (ETNs). The fund may also purchase futures contracts for cash management purposes and to gain investment exposure pending investments.). The fund is also authorized to use various other investment strategies such as investing directly in fixed-income and equity securities, including U.S. government securities, mortgage-backed and asset-backed securities, closed-end funds, and partnerships. The fund may also short-sell securities.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The investment performance of each fund will reflect both its managers' allocation decisions with respect to the underlying funds and the investment decisions made by the underlying funds' managers.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in fixed-income securities than John Hancock Multi-Index Lifestyle Portfolios with greater target allocations to underlying funds that invest primarily in equity securities, fixed-income security risks are more prevalent in this fund than in other, John Hancock Multi-Index Lifestyle  Portfolios. In addition to fixed-income securities risk, the fund's other main risk factors are listed below in alphabetical order.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;

               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions.&lt;/div&gt;

               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;

               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Investment company securities risk.&lt;/b&gt; A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Short sales risk.&lt;/b&gt; In a short sale, a fund pays interest on the borrowed security. The fund will lose money if the security price increases between the short sale and the replacement date.&lt;/div&gt;

U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support.

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;

Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;

               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;

               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;

               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;

               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;

               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;

               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;

               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;

               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;

               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's performance. During its most recent fiscal year, the fund's portfolio turnover rate was 71% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund will invest at least 80% of its net assets (plus any borrowings for investment purposes) in floating-rate loans, which often include debt securities of domestic and foreign issuers that are rated below investment grade (rated below Baa by a nationally recognized statistical rating organization such as Moody's Investors Service, Inc. or BBB by Standard and Poor's Ratings Services), at the time of purchase, or are of comparable quality, as determined by the manager, and other floating-rate securities. Bonds that are rated at or below BB by Standard and Poor's Ratings Services or Ba by Moody's Investors Service, Inc. are considered junk bonds.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in domestic and foreign loans and loan participations that pay interest at rates that float or reset periodically at a margin above a generally recognized base lending rate such as the Prime Rate, the London InterBank Offered Rate (LIBOR), or another generally recognized base lending rate. Loans and debt instruments rated below investment grade are considered speculative. The fund may invest in loans of companies whose financial conditions are troubled or uncertain and that may be involved in bankruptcy proceedings, reorganizations, or financial restructurings. Some loans may be illiquid. The fund may also acquire and hold warrants and other equity interests. The fund may invest in loans, loan participations, and other securities of any maturity and duration. The fund may also invest in loans of any aggregate principal amount, which will vary from time to time.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;For purposes of reducing risk and/or improving liquidity, the fund may invest in derivative instruments such as options (including options on securities indexes) and swaps (including credit default swaps).&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in any number of issuers and may, at times, invest its assets in a small number of issuers. The fund may focus its investments in a particular sector or sectors of the economy. The fund's investment process may result in a higher-than-average portfolio turnover ratio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Changing distribution levels risk.&lt;/b&gt; The fund may cease or reduce the level of its distribution if income or dividends paid from its investments declines.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Distressed investments risk.&lt;/b&gt; Distressed investments, including loans, mortgages, bonds, and notes, may not be publicly traded and may involve substantial risk. A fund may lose up to its entire investment.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, options, and swaps. Options and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;High portfolio turnover risk.&lt;/b&gt; Trading securities actively and frequently can increase transaction costs (thus lowering performance) and taxable distributions.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Loan participations risk.&lt;/b&gt; Participations and assignments involve special types of risks, including credit risk, interest-rate risk, counterparty risk, liquidity risk, risks associated with extended settlement, and the risks of being a lender.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small number of issuers risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for funds which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Warrants risk.&lt;/b&gt; The prices of warrants may not precisely reflect the prices of their underlying securities. Warrant holders do not receive dividends or have voting or credit rights. A warrant ceases to have value if not exercised prior to its expiration date.&lt;/div&gt;

The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's performance. During its most recent fiscal year, the fund's portfolio turnover rate was 25% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in the common stocks of large- and medium-sized blue chip growth companies. The manager defines blue chip growth companies as those well established in their industries and with the potential for above-average earnings growth.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;In identifying blue chip companies in which to invest, the manager generally considers whether they have viable or growing leading market positions, seasoned management teams, and strong financial fundamentals. This investment approach reflects the manager's belief that the combination of solid company fundamentals (with emphasis on the potential for above-average growth in earnings or operating cash flow) and a positive industry outlook will ultimately reward investors. The manager also seeks to invest in some companies with good prospects for dividend growth.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;While most of the assets of the fund are invested in U.S. common stocks, the fund may also invest in other types of securities, including (i) U.S. dollar- and foreign currency-denominated foreign securities (up to 20% of net assets), (ii) convertible stocks, warrants, and bonds, and (iii) futures and options. Combined investments in convertible securities, preferred stocks, and debt securities are limited to 25% of total assets. The fund may invest in debt securities of any type without regard to quality or rating, including those rated below investment-grade (junk bonds) (up to 5% of total assets). The fund's investment policies are based on credit ratings at the time of purchase. The fund's debt securities may include privately negotiated notes or loans, including loan participations and assignments (bank loans). Some loans may be illiquid.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund holds a certain portion of its assets in money market reserves consisting of shares of the T. Rowe Price Government Reserve Fund (or any other internal T. Rowe Price money market fund) or U.S. dollar- and foreign currency-denominated money market securities. These include repurchase agreements in the two highest rating categories that mature in one year or less. The fund may invest reserves in U.S. dollars and foreign currencies.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest up to 10% of its total assets in hybrid instruments. Hybrid instruments are a type of high-risk derivative which can combine the characteristics of securities, futures, and options. Such securities may bear interest or pay dividends at below market rates or even relatively nominal market rates.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;In pursuing the fund's investment objective, the manager may deviate from the fund's normal investment criteria to purchase securities the manager believes might appreciate substantially. The fund may invest significantly in the information technology sector, and the fund may at times invest significantly in stocks of technology companies.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is subject to risks, and you could lose money by investing in the fund. The principal risks of investing in the fund include:&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Currency risk.&lt;/b&gt; Fluctuations in exchange rates may adversely affect the U.S. dollar value of a fund's investments. Foreign currencies may decline in value, which could negatively impact performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: futures contracts and options. Futures contracts and options generally are subject to counterparty risk.&lt;/div&gt;

               &lt;b&gt;Hybrid instrument risk.&lt;/b&gt; Hybrid instruments entail greater market risk and may be more volatile than traditional debt instruments, may bear interest or pay preferred dividends at below-market rates, and may be illiquid. The risks of investing in hybrid instruments are a combination of the risks of investing in securities, options, futures, and currencies.&lt;/div&gt;

               &lt;b&gt;Information technology risk.&lt;/b&gt; Information technology companies can be significantly affected by rapid obsolescence, short product cycles, competition, and government regulation, among other factors. Investments in the technology sector may be susceptible to heightened risk of cybersecurity breaches, which may allow an unauthorized party to gain access to personally identifiable information and other customer data.&lt;/div&gt;

               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;

               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;

               &lt;b&gt;Loan participations risk.&lt;/b&gt; Participations and assignments involve special types of risks, including credit risk, interest-rate risk, counterparty risk, liquidity risk, risks associated with extended settlement, and the risks of being a lender.&lt;/div&gt;

               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mid-sized company risk&lt;/b&gt;. Mid-sized companies are generally less established and may be more volatile than larger companies. Mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;

               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;

               &lt;b&gt;Telecommunications sector risk.&lt;/b&gt; Telecommunication services companies are subject to government regulation of services and rates of return and can be significantly affected by intense competition, among other factors.&lt;/div&gt;

               &lt;b&gt;Warrants risk.&lt;/b&gt; The prices of warrants may not precisely reflect the prices of their underlying securities. Warrant holders do not receive dividends or have voting or credit rights. A warrant ceases to have value if not exercised prior to its expiration date.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;This table describes the fees and expenses that you may pay indirectly if shares of the fund are held by an exempt separate account of certain John Hancock insurance companies that fund exempt group annuity contracts issued by those insurance companies to qualified retirement plans. They are based on expenses incurred during the fund's most recent fiscal year expressed as a percentage of the fund's average net assets during the year. The fees and expenses do not reflect fees and expenses of any separate account that may use the fund as its underlying investment option and would be higher if they did.&lt;/div&gt;

Please see below a hypothetical example showing the expenses of a $10,000 investment for the time periods indicated and then assuming you sell all of your shares at the end of those periods. The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's performance. During its most recent fiscal year, the fund's portfolio turnover rate was 39% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests at least 65% of its total assets in equity and equity-related securities of companies, at the time of investment, that exceed $1 billion in market capitalization and that the manager believes have above average growth prospects. These companies are generally mid-to large-capitalization companies.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The manager follows a highly disciplined investment selection and management process that seeks to identify companies that show superior absolute and relative earnings growth and also are attractively valued. The manager looks for companies that experience some or all of the following: (i) above-average revenue and earnings per share growth, (ii) strong market position, (iii) improving profitability and distinctive attributes such as unique marketing ability, (iv) strong research and development and productive new product flow, and (v) financial strength. Such companies generally trade at high prices relative to their current earnings. Earnings predictability and confidence in earnings forecasts are important parts of the selection process.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Securities in which the fund invests have historically been more volatile than the S&amp;amp;P 500 Index. Also, companies that have an earnings growth rate higher than that of the average S&amp;amp;P 500 company tend to reinvest their earnings rather than distribute them. Therefore, the fund is not likely to receive significant dividend income on its securities. Seeking to invest in companies with above market-average growth, the fund may invest significantly in sectors associated with such growth, including information technology.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;In addition to common stocks, nonconvertible preferred stock and convertible securities, equity-related securities in which the fund invests include: (i) American Depositary Receipts (ADRs); (ii) warrants and rights; (iii) investments in various types of business ventures, including partnerships and joint ventures; (iv) real estate investment trusts (REITs); and (v) initial public offerings (IPOs) and similar securities. (Convertible securities are securities &#8212;like bonds, corporate notes and preferred stocks&#8212;that the fund can convert into the company's common stock, cash value of common stock, or some other equity security.)&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;In addition to the principal strategies discussed above, the fund may also use the following investment strategies to attempt to increase the fund's return or protect its assets if market conditions warrant:&lt;/div&gt;            
            &lt;ul&gt;&lt;li&gt;                  
                  &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may make short sales of a security including short sales "against the box."&lt;/div&gt;               
               &lt;/li&gt;&lt;li&gt;                  
                  &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest up to 20% of its total assets in foreign equity securities. (For purposes of this 20% limit, ADRs and other similar receipts or shares traded in U.S. markets are not considered to be foreign securities.)&lt;/div&gt;               
               &lt;/li&gt;&lt;li&gt;                  
                  &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in U.S. government securities issued or guaranteed by the U.S. government or by an agency or instrumentality of the U.S. government.&lt;/div&gt;               
               &lt;/li&gt;&lt;li&gt;                  
                  &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in mortgage-related securities issued or guaranteed by U.S. governmental entities, including collateralized mortgage obligations, multi-class pass-through securities and stripped mortgage-backed securities.&lt;/div&gt;               
               &lt;/li&gt;&lt;li&gt;                  
                  &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in fixed-income securities rated investment grade. These include corporate debt and other debt obligations of U.S. and foreign issuers. The fund may invest in obligations that are not rated, but that the manager believes are of comparable quality to these obligations.&lt;/div&gt;               
               &lt;/li&gt;&lt;li&gt;                  
                  &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in repurchase agreements.&lt;/div&gt;               
               &lt;/li&gt;&lt;/ul&gt;
            
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The manager considers selling or reducing a stock position when, in the opinion of the manager, the stock has experienced a fundamental disappointment in earnings, it has reached an intermediate price objective and its outlook no longer seems sufficiently promising, a relatively more attractive stock emerges or the stock has experienced adverse price movement. The fund may focus its investments in a particular sector or sectors of the economy.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund's investment process may, at times, result in a higher than average portfolio turnover ratio and increased trading expenses.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is subject to risks, and you could lose money by investing in the fund. The principal risks of investing in the fund include:&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;High portfolio turnover risk.&lt;/b&gt; Trading securities actively and frequently can increase transaction costs (thus lowering performance) and taxable distributions.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Information technology risk.&lt;/b&gt; Information technology companies can be significantly affected by rapid obsolescence, short product cycles, competition, and government regulation, among other factors. Investments in the technology sector may be susceptible to heightened risk of cybersecurity breaches, which may allow an unauthorized party to gain access to personally identifiable information and other customer data.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mid-sized company risk&lt;/b&gt;. Mid-sized companies are generally less established and may be more volatile than larger companies. Mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Real estate investment trust risk.&lt;/b&gt; REITs, pooled investment vehicles that typically invest in real estate directly or in loans collateralized by real estate, carry risks associated with owning real estate, including the potential for a decline in value due to economic or market conditions.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Real estate securities risk.&lt;/b&gt; Securities of companies in the real estate industry carry risks associated with owning real estate, including the potential for a decline in value due to economic or market conditions.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;

               &lt;b&gt;Short sales risk.&lt;/b&gt; In a short sale, a fund pays interest on the borrowed security. The fund will lose money if the security price increases between the short sale and the replacement date.&lt;/div&gt;

               &lt;b&gt;Warrants risk.&lt;/b&gt; The prices of warrants may not precisely reflect the prices of their underlying securities. Warrant holders do not receive dividends or have voting or credit rights. A warrant ceases to have value if not exercised prior to its expiration date.&lt;/div&gt;

The example assumes a 5% average annual return and that fund expenses will not change over the periods.

A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's performance. During its most recent fiscal year, the fund's portfolio turnover rate was 277% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is subject to risks, and you could lose money by investing in the fund. The principal risks of investing in the fund include:&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Changing distribution levels risk.&lt;/b&gt; The fund may cease or reduce the level of its distribution if income or dividends paid from its investments declines.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: futures contracts, reverse repurchase agreements, and options. Futures contracts and options generally are subject to counterparty risk. An event of default or insolvency of the counterparty to a reverse repurchase agreement could result in delays or restrictions with respect to the fund's ability to dispose of the underlying securities. In addition, a reverse repurchase agreement may be considered a form of leverage and may, therefore, increase fluctuations in the fund's net asset value per share (NAV).&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;High portfolio turnover risk.&lt;/b&gt; Trading securities actively and frequently can increase transaction costs (thus lowering performance) and taxable distributions.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;

Please see below a hypothetical example showing the expenses of a $10,000 investment for the time periods indicated and then assuming you sell all of your shares at the end of those periods. The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's performance. During its most recent fiscal year, the fund's portfolio turnover rate was 19% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in equity securities, with at least 65% in common stocks of well-established companies paying above-average dividends. The fund employs a "value" approach and invests in stocks and other securities that appear to be undervalued by various measures but have good prospects for capital appreciation and dividend growth.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, substantial dividend income means that the yield on the fund's portfolio securities generally exceeds the yield on the fund's benchmark. The manager believes that income can contribute significantly to total return over time and expects the fund's yield to exceed that of the Russell 1000 Value Index. While the price of a company's stock can go up or down, stocks paying a high level of dividend income tend to be less volatile than those paying a lower level and may help offset losses in falling markets.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund will generally consider companies with established operating histories, above-average dividend yield or low price/earnings ratios relative to the Russell 1000 Value Index, positive financial characteristics, and/or low stock price relative to a company's underlying value. The fund may also purchase other types of securities in keeping with its objective, including: (i) U.S. dollar-and foreign currency-denominated foreign securities (up to 25% of total assets); (ii) preferred stocks; (iii) convertible stocks, bonds, and warrants; (iv) futures and options; and (v) bank debt, loan participations, and assignments.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in fixed-income securities without regard to quality or rating, including privately negotiated notes or loans (including loan participations and assignments (bank loans)) and up to 10% in below-investment-grade fixed-income securities (junk bonds). The fund's fixed-income investments may include privately negotiated notes or loans, including loan participations and assignments (bank loans). Some loans may be illiquid.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund holds a certain portion of its assets in money market reserves consisting of shares of the T. Rowe Price Government Reserve Fund (or any other internal T. Rowe Price money market fund) or U.S. dollar- and foreign currency-denominated money market securities. These include repurchase agreements in the two highest rating categories that mature in one year or less. The fund may invest reserves in U.S. dollars and foreign currencies.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest up to 10% of its total assets in hybrid instruments. Hybrid instruments are a type of high-risk derivative which can combine the characteristics of securities, futures, and options. Such securities may bear interest or pay dividends at below market rates or even relatively nominal market rates.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;In pursuing the fund's investment objective, the manager may deviate from the fund's normal investment criteria to purchase securities the manager believes might appreciate substantially. The fund may invest significantly in certain sectors, such as the financials sector.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is subject to risks, and you could lose money by investing in the fund. The principal risks of investing in the fund include:&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Changing distribution levels risk.&lt;/b&gt; The fund may cease or reduce the level of its distribution if income or dividends paid from its investments declines.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Currency risk.&lt;/b&gt; Fluctuations in exchange rates may adversely affect the U.S. dollar value of a fund's investments. Foreign currencies may decline in value, which could negatively impact performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: futures contracts and options. Futures contracts and options generally are subject to counterparty risk.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hybrid instrument risk.&lt;/b&gt; Hybrid instruments entail greater market risk and may be more volatile than traditional debt instruments, may bear interest or pay preferred dividends at below-market rates, and may be illiquid. The risks of investing in hybrid instruments are a combination of the risks of investing in securities, options, futures, and currencies.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Investment company securities risk.&lt;/b&gt; A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Loan participations risk.&lt;/b&gt; Participations and assignments involve special types of risks, including credit risk, interest-rate risk, counterparty risk, liquidity risk, risks associated with extended settlement, and the risks of being a lender.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Warrants risk.&lt;/b&gt; The prices of warrants may not precisely reflect the prices of their underlying securities.

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The following information illustrates the variability of the fund's returns and provides some indication of the risks of investing in the fund by showing changes in the fund's performance from year to year and by showing how the fund's average annual returns compared with a broad-based market index. Past performance (before and after taxes) does not indicate future results. The Russell 1000 Value Index shows how the fund's performance compares against the returns of similar investments. All figures assume dividend reinvestment. Performance information is updated daily, monthly, and quarterly and may be obtained at our website, jhinvestments.com, or by calling 800-344-1029 between 8:00 A.M. and 7:00 P.M., Eastern time, on most business days.&lt;/div&gt;

The example assumes a 5% average annual return and that fund expenses will not change over the periods.

A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's performance. During its most recent fiscal year, the fund's portfolio turnover rate was 31% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in fixed-income instruments that are economically tied to at least three countries (one of which may be the United States), which may be represented by futures contracts (including related options) with respect to such securities, and options on such securities. These fixed-income instruments may be denominated in foreign currencies or in U.S. dollars, which may be represented by forwards or derivatives, such as options, futures contracts, or swap agreements.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;In selecting securities for the fund, the manager utilizes economic forecasting, interest rate anticipation, credit and call risk analysis, foreign currency exchange rate forecasting, and other security selection techniques. The proportion of the fund's assets committed to investment in securities with particular characteristics (such as maturity, type and coupon rate) will vary based on the manager's outlook for the U.S. and foreign economies, the financial markets, and other factors.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Fixed-income securities may have fixed, variable, or floating rates of interest, including rates of interest that vary inversely at a multiple of a designated or floating rate, or that vary according to change in relative values of currencies.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Depending on the manager's current opinion as to the proper allocation of assets among domestic and foreign issuers, investments that are economically tied to foreign countries will normally be at least 25% of the fund's net assets. The fund may invest, without limitation, in securities and instruments that are economically tied to emerging countries. The fund may invest up to 20% of its total assets in fixed-income securities that are rated below investment grade of any rating. The fund's investment policies are based on credit ratings at the time of purchase. The fund may invest in baskets of foreign currencies (such as the euro) and directly in currencies. The average portfolio duration of the fund normally varies within three years (plus or minus) of the duration of the benchmark index, as calculated by the manager.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest up to 10% of its total assets in preferred stocks. The fund may have significant investments in fixed-income instruments issued by companies in the financial services sector.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund's investment process may, at times, result in a higher than average portfolio turnover ratio and increased trading expenses.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may make short sales of a security including short sales "against the box."&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is a non-diversified fund, which means that it may invest in a smaller number of issuers than a diversified fund and may invest more of its assets in the securities of a single issuer.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may:&lt;/div&gt;            
            &lt;ul&gt;&lt;li&gt;

               &lt;/li&gt;&lt;li&gt;                  
                  &lt;div style="font-size:10pt;padding-top:0;padding-bottom:0;padding-left:0;"&gt;purchase and sell futures and options on futures,&lt;/div&gt;               
               &lt;/li&gt;&lt;li&gt;                  
                  &lt;div style="font-size:10pt;padding-top:0;padding-bottom:0;padding-left:0;"&gt;purchase and sell currency or securities on a forward basis, and&lt;/div&gt;               
               &lt;/li&gt;&lt;li&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is subject to risks, and you could lose money by investing in the fund. The principal risks of investing in the fund include:&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Changing distribution levels risk.&lt;/b&gt; The fund may cease or reduce the level of its distribution if income or dividends paid from its investments declines.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Currency risk.&lt;/b&gt; Fluctuations in exchange rates may adversely affect the U.S. dollar value of a fund's investments. Foreign currencies may decline in value, which could negatively impact performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, foreign currency swaps, total return swaps, futures contracts, options on futures, interest-rate swaps, inverse floating-rate securities, options, reverse repurchase agreements, and swaps. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk. An event of default or insolvency of the counterparty to a reverse repurchase agreement could result in delays or restrictions with respect to the fund's ability to dispose of the underlying securities. In addition, a reverse repurchase agreement may be considered a form of leverage and may, therefore, increase fluctuations in the fund's net asset value per share (NAV).&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;High portfolio turnover risk.&lt;/b&gt; Trading securities actively and frequently can increase transaction costs (thus lowering performance) and taxable distributions.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hybrid instrument risk.&lt;/b&gt; Hybrid instruments entail greater market risk and may be more volatile than traditional debt instruments, may bear interest or pay preferred dividends at below-market rates, and may be illiquid. The risks of investing in hybrid instruments are a combination of the risks of investing in securities, options, futures, and currencies.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Loan participations risk.&lt;/b&gt; Participations and assignments involve special types of risks, including credit risk, interest-rate risk, counterparty risk, liquidity risk, risks associated with extended settlement, and the risks of being a lender.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors. To the extent that a fund invests in securities of companies in the financial services sector, the fund may be significantly affected by economic, market, and business developments, borrowing costs, interest-rate fluctuations, competition, and government regulation, among other factors, impacting that sector.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Short sales risk.&lt;/b&gt; In a short sale, a fund pays interest on the borrowed security. The fund will lose money if the security price increases between the short sale and the replacement date.&lt;/div&gt;

The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's performance. During its most recent fiscal year, the fund's portfolio turnover rate was 60% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests at least 80% of its net assets (plus any borrowings for investment purposes) at the time of investment in high yield securities. The fund's investments may include corporate bonds, preferred stocks, U.S. government and foreign securities, mortgage-backed securities, loan assignments or participations and convertible securities which have the following ratings (or, if unrated, are considered by the manager to be of equivalent quality):&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Below-investment-grade securities are commonly referred to as "junk bonds." The fund may also invest in investment-grade securities.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;As part of its investment strategy, the fund will generally invest without restrictions within these ratings category ranges, or in unrated securities considered to be of equivalent quality by the manager.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in foreign bonds and other fixed-income securities denominated in foreign currencies, where, in the opinion of the manager, the combination of current yield and currency value offer attractive expected returns. Foreign securities in which the fund may invest include emerging market securities. The fund may invest up to 100% of its assets in foreign securities.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may also enter into various derivative transactions for both hedging and non-hedging purposes, including for purposes of enhancing returns. These derivative transactions include, but are not limited to, futures, options, swaps and forwards. In particular, the fund may use interest rate swaps, credit default swaps (on individual securities and/or baskets of securities), futures contracts and/or mortgage-backed securities to a significant extent, although the amounts invested in these instruments may change from time to time.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in fixed- and floating-rate loans, generally in the form of loan participations and assignments of such loans.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund normally maintains an average portfolio duration of between three and seven years. However, the fund may invest in individual securities of any duration. Duration is an approximate measure of the sensitivity of the market value of a security to changes in interest rates.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is subject to risks, and you could lose money by investing in the fund. The principal risks of investing in the fund include:&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Changing distribution levels risk.&lt;/b&gt; The fund may cease or reduce the level of its distribution if income or dividends paid from its investments declines.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, futures contracts, options, swaps and interest-rate swaps. Futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Loan participations risk.&lt;/b&gt; Participations and assignments involve special types of risks, including credit risk, interest-rate risk, counterparty risk, liquidity risk, risks associated with extended settlement, and the risks of being a lender.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;This table describes the fees and expenses that you may pay indirectly if shares of the fund are held by an exempt separate account of certain John Hancock insurance companies that fund exempt group annuity contracts issued by those insurance companies to qualified retirement plans. They are based on expenses incurred during the fund's most recent fiscal year expressed as a percentage of the fund's average net assets during the year. The fees and expenses do not reflect fees and expenses of any separate account that may use the fund as its underlying investment option and would be higher if they did.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;This example is intended to help you compare the cost of investing in the fund with the cost of investing in other mutual funds. Please see below a hypothetical example showing the expenses of a $10,000 investment for the time periods indicated and then assuming you sell all of your shares at the end of those periods. The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's performance. During its most recent fiscal year, the fund's portfolio turnover rate was 30% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in investments of smaller companies outside the U.S., including emerging markets, which have total stock market capitalizations or annual revenues of $4 billion or less.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;In some emerging markets, the fund may invest in companies that qualify as smaller companies but that still are among the largest in the market. The fund may also invest in depository receipts and may invest a portion of its assets in the equity securities of larger foreign companies.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;An equity security, or stock, represents a proportionate share of the ownership of a company; its value is based on the success of the company's business, any income paid to stockholders, the value of its assets, and general market conditions. Common stocks, preferred stocks and convertible securities are examples of equity securities. Convertible securities generally are debt securities or preferred stock that may be converted into common stock after a certain time period or under certain circumstances.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest more than 25% of its total assets in the securities of issuers located in any one country. The fund may focus its investments in a particular sector or sectors of the economy.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;When choosing equity investments for this fund, the manager applies a "bottom up," value-oriented, long-term approach, focusing on the market price of a company's securities relative to the manager's evaluation of the company's long-term earnings, asset value and cash flow potential. The manager also considers a company's price/earnings ratio, profit margins and liquidation value and other factors.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is subject to risks, and you could lose money by investing in the fund. The principal risks of investing in the fund include:&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

Please see below a hypothetical example showing the expenses of a $10,000 investment for the time periods indicated and then assuming you sell all of your shares at the end of those periods. The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's performance. During its most recent fiscal year, the fund's portfolio turnover rate was 29% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests primarily in equity securities of companies located outside the U.S., including in emerging markets. Although the manager will search for investments across a large number of countries and sectors, from time to time, based on economic conditions, the fund may have significant positions in particular countries or sectors such as technology (including computer hardware and software, electronics, and telecommunications) and financial institutions.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Equity securities generally entitle the holder to participate in a company's general operating results. These include common stocks and preferred stocks. The fund also invests in American Depositary Receipts (ADRs), European Depositary Receipts (EDRs) and Global Depositary Receipts (GDRs), which are certificates typically issued by a bank or trust company that give their holders the right to receive securities issued by a foreign or domestic company.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in debt securities of countries and governments located anywhere in the world, as well as in equity-linked notes.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The manager's investment philosophy is "bottom-up," value-oriented, and long-term. In choosing equity investments, the manager will focus on the market price of a company's securities relative to its evaluation of the company's long-term earnings, asset value and cash flow potential. A company's historical value measure, including price/earnings ratio, profit margins and liquidation value, will also be considered.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: equity-linked notes (equity-linked notes generally reflect the risks associated with their underlying securities, depend on the credit of the note's issuer, may be privately placed, and may have a limited secondary market). &lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;

               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors. To the extent that a fund invests in securities of companies in the financial services sector, the fund may be significantly affected by economic, market, and business developments, borrowing costs, interest-rate fluctuations, competition, and government regulation, among other factors, impacting that sector.&lt;/div&gt;

               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

               &lt;b&gt;Telecommunications sector risk.&lt;/b&gt; Telecommunication services companies are subject to government regulation of services and rates of return and can be significantly affected by intense competition, among other factors.&lt;/div&gt;

               &lt;b&gt;Value investing style risk.&lt;/b&gt; The fund emphasizes a value style of investing, which focuses on undervalued companies with characteristics for improved valuations. This style of investing is subject to the risk that the valuations never improve or that the returns on value equity securities are less than returns on other styles of investing or the overall stock market. Value stocks also may decline in price, even though in theory they are already underpriced.&lt;/div&gt;

The example assumes a 5% average annual return and that fund expenses will not change over the periods.

A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's performance. During its most recent fiscal year, the fund's portfolio turnover rate was 67% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The manager's investment approach is based primarily on proprietary fundamental analysis. Fundamental analysis involves the assessment of a company through such factors as its business environment, management, balance sheet, income statement, anticipated earnings, revenues and other related measures of value. In analyzing companies for investment, the manager looks for, among other things, a strong balance sheet, strong earnings growth, attractive industry dynamics, strong competitive advantages (e.g., strong management teams), and attractive relative value within the context of a security's primary trading market. Securities are sold when the investment has achieved its intended purpose, or because it is no longer considered attractive. The fund may invest up to 25% of its total assets in foreign securities, including emerging market securities. The fund may focus its investments in a particular sector or sectors of the economy.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund's investment process may, at times, result in a higher than average portfolio turnover ratio and increased trading expenses.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is subject to risks, and you could lose money by investing in the fund. The principal risks of investing in the fund include:&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;High portfolio turnover risk.&lt;/b&gt; Trading securities actively and frequently can increase transaction costs (thus lowering performance) and taxable distributions.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mid-sized company risk&lt;/b&gt;. Mid-sized companies are generally less established and may be more volatile than larger companies. Mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Privately held and newly public companies risk.&lt;/b&gt; Investments in the stocks of privately held companies and newly public companies involve greater risks than investments in stocks of companies that have traded publicly on an exchange for extended time periods. Investments in such companies are less liquid and may be difficult to value. There may be significantly less information available about these companies' business models, quality of management, earnings growth potential, and other criteria used to evaluate their investment prospects. The extent (if at all) to which securities of privately held companies or newly public companies may be sold without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Funds with principal investment strategies that involve investments in securities of privately held companies tend to have a greater exposure to liquidity risk than funds that do not invest in securities of privately held companies.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;

Please see below a hypothetical example showing the expenses of a $10,000 investment for the time periods indicated and then assuming you sell all of your shares at the end of those periods. The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 49% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests substantially all of its assets in underlying funds using an asset allocation strategy designed for investors expected to retire around the year 2010.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The portfolio managers of the fund allocate assets among the underlying funds according to an asset allocation strategy that becomes increasingly conservative over time. John Hancock Multi-Index 2010 Lifetime Portfolio has a target asset allocation of 38.75% of its assets in underlying funds that invest primarily in equity securities. The fund will have a greater exposure to underlying funds that invest primarily in fixed-income securities than will a John Hancock Multi-Index Lifetime Portfolio with a more distant target date. To reduce investment risk and volatility as retirement approaches and in the postretirement years, the asset allocation strategy will change over time according to a predetermined "glide path" shown in the following chart. The fund may be a primary source of income for its shareholders after retirement.&lt;/div&gt;         
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                  GLIDE PATH CHART               
               &lt;/b&gt;&lt;/div&gt;  
 &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;/div&gt;           
                    &lt;img alt="glidepath chart" src="glidepath3.jpg"&gt;&lt;/img&gt;    
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The allocations reflected in the glide path are referred to as target allocations because they do not reflect active decisions made by the portfolio managers to produce an overweight or an underweight position in a particular asset class. The fund has a target allocation to underlying funds that invest in the broad asset classes of equity and fixed-income securities, but may also allocate its assets to underlying funds that invest outside these asset classes to protect the fund or help it achieve its objective. For example, the fund may also allocate its assets to underlying funds that invest in alternative and specialty asset classes. The managers may change the target allocation without shareholder approval if they believe that such change would benefit the fund and its shareholders. Under normal circumstances, any deviation from the target allocation is not expected to be greater than plus or minus 10%.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Within the prescribed percentage allocation, the managers select the percentage level to be maintained in specific underlying funds. New investments made by the fund may be directed to particular underlying funds in an effort to maintain the desired target allocations. There is no guarantee that the portfolio managers will correctly predict the market or economic conditions and, as with other mutual fund investments, you could lose money even if the fund is at or close to its designated retirement year or in its postretirement stage.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is designed for investors who may remain invested in the fund through their retirement years. The fund will continue to be managed according to an allocation strategy that becomes increasingly conservative over time until approximately twenty years after retirement, at which time the fund expects to maintain a static allocation of approximately 25% of its assets in equity underlying funds.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in underlying funds that invest in a broad range of equity, fixed-income, and alternative/specialty securities and asset classes, including, but not limited to, U.S. and foreign securities, including emerging-market securities, commodities, asset-backed securities, small-cap securities, and below-investment-grade securities (i.e., junk bonds). The underlying funds may also use derivatives, such as swaps, foreign currency forwards, futures, and options, in each case for the purposes of reducing risk, obtaining efficient market exposure and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund will invest in various passively managed underlying funds that as a group hold a wide range of equity-type securities in their portfolios, including convertible securities. The fund may also invest in various actively managed funds. The fund is not designed to track an index or group of indexes. Equity-type securities include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. Certain equity underlying funds may invest in initial public offerings (IPOs). Each of the equity underlying funds has its own investment strategy that, for example, may focus on growth stocks or value stocks, or may employ a strategy combining growth and income stocks, and/or may invest in derivatives such as credit default swaps, foreign currency forwards, interest rate swaps, options on securities, and futures contracts. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from shorter to longer term. The fixed-income underlying funds collectively hold various types of debt instruments such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging market securities). Certain underlying funds may invest in illiquid securities, and certain underlying funds may be non-diversified.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest directly in exchange-traded funds (ETFs), exchange-traded notes (ETNs), the securities of other investment companies, U.S. government securities, and other types of investments such as derivatives, including credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, in each case for the purposes of reducing risk, obtaining efficient market exposure, and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;To the extent permitted by law, the Board of Trustees of the fund may, in its discretion, determine to combine the fund with another fund without shareholder approval if the target allocation of the fund matches the target allocation of the other fund, although there is no assurance that the Board of Trustees will so determine at any point. The fund bears its own expenses and, in addition, indirectly bears its proportionate share of the expenses of the underlying funds in which it invests. The fund's performance reflects both the managers' allocation decisions and the performance of the underlying funds.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is subject to risks, and you could lose money by investing in the fund. The principal risks of investing in the fund are listed below.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in fixed-income securities than John Hancock Multi-Index Lifetime Portfolios with more distant target dates, fixed-income risks are more prevalent in this fund than in these other target date funds. In addition to fixed-income securities risk, the fund's other main risk factors are listed in alphabetical order.&lt;/div&gt;          
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                &lt;i&gt;  Principal risks of investing in the fund of funds   &lt;/i&gt;            
               &lt;/b&gt;&lt;/div&gt;             
                     
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk based on the nature of their support.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;

               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Target allocation risk.&lt;/b&gt; The fund's risk profile will change due to reallocation or rebalancing of portfolio assets as the fund approaches its target date.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;

               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The following information illustrates the variability of the fund's returns and provides some indication of the risks of investing in the fund by showing changes in the fund's performance from year to year and by showing how the fund's average annual returns compared with a broad-based market index. Past performance (before and after taxes) does not indicate future results. All figures assume dividend reinvestment. Performance information is updated daily, monthly, and quarterly and may be obtained at our website, jhinvestments.com, or by calling 800-344-1029 between 8:00 A.M. and 7:00 P.M., Eastern time, on most business days.&lt;/div&gt;

The information shows how the fund's performance compares with the returns of an index of funds with similar investment objectives. From December 1, 2016 to November 30, 2017, the Custom Benchmark consisted of the following indices and approximate weightings: 28.88% Russell 3000 Index, 12.37% MSCI ACWI ex-USA Index, 47.00% Bloomberg Barclays U.S. Aggregate Bond Index, and 11.75% ICE Bank of America Merrill Lynch U.S. High Yield Master II Index. The weightings of the indices in the Custom Benchmark are adjusted annually to reflect changes in the fund's target asset allocation in accordance with the annual roll-down of the glide path described above and differed in periods prior to December 1, 2016.&lt;/div&gt;

The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 28% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests substantially all of its assets in underlying funds using an asset allocation strategy designed for investors expected to retire around the year 2015.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The portfolio managers of the fund allocate assets among the underlying funds according to an asset allocation strategy that becomes increasingly conservative over time. John Hancock Multi-Index 2015 Lifetime Portfolio has a target asset allocation of 45% of its assets in underlying funds that invest primarily in equity securities. The fund will have a greater exposure to underlying funds that invest primarily in fixed-income securities than will a Multi-Index Lifetime Portfolio with a more distant target date. To reduce investment risk and volatility as retirement approaches and in the postretirement years, the asset allocation strategy will change over time according to a predetermined "glide path" shown in the following chart. The fund may be a primary source of income for its shareholders after retirement.&lt;/div&gt;         
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                  GLIDE PATH CHART               
               &lt;/b&gt;&lt;/div&gt;       
 &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;/div&gt;      
                    &lt;img alt="glidepath chart" src="glidepath3.jpg"&gt;&lt;/img&gt;    
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The allocations reflected in the glide path are referred to as target allocations because they do not reflect active decisions made by the portfolio managers to produce an overweight or an underweight position in a particular asset class. The fund has a target allocation to underlying funds that invest in the broad asset classes of equity and fixed-income securities, but may also allocate its assets to underlying funds that invest outside these asset classes to protect the fund or help it achieve its objective. For example, the fund may also allocate its assets to underlying funds that invest in alternative and specialty asset classes. The managers may change the target allocation without shareholder approval if they believe that such change would benefit the fund and its shareholders. Under normal circumstances, any deviation from the target allocation is not expected to be greater than plus or minus 10%.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Within the prescribed percentage allocation, the managers select the percentage level to be maintained in specific underlying funds. New investments made by the fund may be directed to particular underlying funds in an effort to maintain the desired target allocations. There is no guarantee that the portfolio managers will correctly predict the market or economic conditions and, as with other mutual fund investments, you could lose money even if the fund is at or close to its designated retirement year or in its postretirement stage.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is designed for investors who may remain invested in the fund through their retirement years. The fund will continue to be managed according to an allocation strategy that becomes increasingly conservative over time until approximately twenty years after retirement, at which time the fund expects to maintain a static allocation of approximately 25% of its assets in equity underlying funds.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in underlying funds that invest in a broad range of equity, fixed-income, and alternative/specialty securities and asset classes, including, but not limited to, U.S. and foreign securities, including emerging-market securities, commodities, asset-backed securities, small-cap securities, and below-investment-grade securities (i.e., junk bonds). The underlying funds may also use derivatives, such as swaps, foreign currency forwards, futures, and options, in each case for the purposes of reducing risk, obtaining efficient market exposure and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund will invest in various passively managed underlying funds that as a group hold a wide range of equity-type securities in their portfolios, including convertible securities. The fund may also invest in various actively managed funds. The fund is not designed to track an index or group of indexes. Equity-type securities include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. Certain equity underlying funds may invest in initial public offerings (IPOs). Each of the equity underlying funds has its own investment strategy that, for example, may focus on growth stocks or value stocks, or may employ a strategy combining growth and income stocks, and/or may invest in derivatives such as credit default swaps, foreign currency forwards, interest rate swaps, options on securities, and futures contracts. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from shorter to longer term. The fixed-income underlying funds collectively hold various types of debt instruments such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging market securities). Certain underlying funds may invest in illiquid securities, and certain underlying funds may be non-diversified.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest directly in exchange-traded funds (ETFs), exchange-traded notes (ETNs), the securities of other investment companies, U.S. government securities, and other types of investments such as derivatives, including credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, in each case for the purposes of reducing risk, obtaining efficient market exposure, and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;To the extent permitted by law, the Board of Trustees of the fund may, in its discretion, determine to combine the fund with another fund without shareholder approval if the target allocation of the fund matches the target allocation of the other fund, although there is no assurance that the Board of Trustees will so determine at any point. The fund bears its own expenses and, in addition, indirectly bears its proportionate share of the expenses of the underlying funds in which it invests. The fund's performance reflects both the managers' allocation decisions and the performance of the underlying funds.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is subject to risks, and you could lose money by investing in the fund. The principal risks of investing in the fund are listed below.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in fixed-income securities than John Hancock Multi-Index Lifetime Portfolios with more distant target dates, fixed-income risks are more prevalent in this fund than in these other target date funds. In addition to fixed-income securities risk, the fund's other main risk factors are listed in alphabetical order.&lt;/div&gt;

                &lt;i&gt;  Principal risks of investing in the fund of funds  &lt;/i&gt;             
               &lt;/b&gt;&lt;/div&gt;             
                     
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk based on the nature of their support.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;

               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;

               &lt;i&gt;   Principal risks of investing in the underlying funds  &lt;/i&gt;             
               &lt;/b&gt;&lt;/div&gt;             
                     
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The following information illustrates the variability of the fund's returns and provides some indication of the risks of investing in the fund by showing changes in the fund's performance from year to year and by showing how the fund's average annual returns compared with a broad-based market index. Past performance (before and after taxes) does not indicate future results. All figures assume dividend reinvestment. Performance information is updated daily, monthly, and quarterly and may be obtained at our website, jhinvestments.com, or by calling 800-344-1029 between 8:00 A.M. and 7:00 P.M., Eastern time, on most business days.&lt;/div&gt;

The information shows how the fund's performance compares with the returns of an index of funds with similar investment objectives. From December 1, 2016 to November 30, 2017, the Custom Benchmark consisted of the following indices and approximate weightings: 33.25% Russell 3000 Index, 14.25% MSCI ACWI ex-USA Index, 42.00% Bloomberg Barclays U.S. Aggregate Bond Index, and 10.50% ICE Bank of America Merrill Lynch U.S. High Yield Master II Index. The weightings of the indices in the Custom Benchmark are adjusted annually to reflect changes in the fund's target asset allocation in accordance with the annual roll-down of the glide path described above and differed in periods prior to December 1, 2016.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 30% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests substantially all of its assets in underlying funds using an asset allocation strategy designed for investors expected to retire around the year 2020.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The portfolio managers of the fund allocate assets among the underlying funds according to an asset allocation strategy that becomes increasingly conservative over time. John Hancock Multi-Index 2020 Lifetime Portfolio has a target asset allocation of 54% of its assets in underlying funds that invest primarily in equity securities. The fund will have a greater exposure to underlying funds that invest primarily in equity securities than will a John Hancock Multi-Index Lifetime Portfolio with a closer target date. To reduce investment risk and volatility as retirement approaches and in the postretirement years, the asset allocation strategy will change over time according to a predetermined "glide path" shown in the following chart. The fund may be a primary source of income for its shareholders after retirement.&lt;/div&gt;         
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                  GLIDE PATH CHART               
               &lt;/b&gt;&lt;/div&gt; 
 &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;/div&gt;            
                   &lt;img alt="glidepath chart" src="glidepath3.jpg"&gt;&lt;/img&gt;     
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The allocations reflected in the glide path are referred to as target allocations because they do not reflect active decisions made by the portfolio managers to produce an overweight or an underweight position in a particular asset class. The fund has a target allocation to underlying funds that invest in the broad asset classes of equity and fixed-income securities, but may also allocate its assets to underlying funds that invest outside these asset classes to protect the fund or help it achieve its objective. For example, the fund may also allocate its assets to underlying funds that invest in alternative and specialty asset classes. The managers may change the target allocation without shareholder approval if they believe that such change would benefit the fund and its shareholders. Under normal circumstances, any deviation from the target allocation is not expected to be greater than plus or minus 10%.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Within the prescribed percentage allocation, the managers select the percentage level to be maintained in specific underlying funds. New investments made by the fund may be directed to particular underlying funds in an effort to maintain the desired target allocations. There is no guarantee that the portfolio managers will correctly predict the market or economic conditions and, as with other mutual fund investments, you could lose money even if the fund is at or close to its designated retirement year or in its postretirement stage.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is designed for investors who may remain invested in the fund through their retirement years. The fund will continue to be managed according to an allocation strategy that becomes increasingly conservative over time until approximately twenty years after retirement, at which time the fund expects to maintain a static allocation of approximately 25% of its assets in equity underlying funds.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in underlying funds that invest in a broad range of equity, fixed-income, and alternative/specialty securities and asset classes, including, but not limited to, U.S. and foreign securities, including emerging-market securities, commodities, asset-backed securities, small-cap securities, and below-investment-grade securities (i.e., junk bonds). The underlying funds may also use derivatives, such as swaps, foreign currency forwards, futures, and options, in each case for the purposes of reducing risk, obtaining efficient market exposure and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund will invest in various passively managed underlying funds that as a group hold a wide range of equity-type securities in their portfolios, including convertible securities. The fund may also invest in various actively managed funds. The fund is not designed to track an index or group of indexes. Equity-type securities include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. Certain equity underlying funds may invest in initial public offerings (IPOs). Each of the equity underlying funds has its own investment strategy that, for example, may focus on growth stocks or value stocks, or may employ a strategy combining growth and income stocks, and/or may invest in derivatives such as credit default swaps, foreign currency forwards, interest rate swaps, options on securities, and futures contracts. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from shorter to longer term. The fixed-income underlying funds collectively hold various types of debt instruments such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging market securities). Certain underlying funds may invest in illiquid securities, and certain underlying funds may be non-diversified.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest directly in exchange-traded funds (ETFs), exchange-traded notes (ETNs), the securities of other investment companies, U.S. government securities, and other types of investments such as derivatives, including credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, in each case for the purposes of reducing risk, obtaining efficient market exposure, and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;To the extent permitted by law, the Board of Trustees of the fund may, in its discretion, determine to combine the fund with another fund without shareholder approval if the target allocation of the fund matches the target allocation of the other fund, although there is no assurance that the Board of Trustees will so determine at any point. The fund bears its own expenses and, in addition, indirectly bears its proportionate share of the expenses of the underlying funds in which it invests. The fund's performance reflects both the managers' allocation decisions and the performance of the underlying funds.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is subject to risks, and you could lose money by investing in the fund. The principal risks of investing in the fund are listed below.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in equity securities than John Hancock Multi-Index Lifetime Portfolios with closer target dates, equity security risks are more prevalent in this fund than in these other target-date funds. In addition to equity securities risk, the fund's other main risk factors are listed in alphabetical order.&lt;/div&gt;          
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                 &lt;i&gt; Principal risks of investing in the fund of funds  &lt;/i&gt;             
               &lt;/b&gt;&lt;/div&gt;             
                     
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk based on the nature of their support.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;

               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;

               &lt;b&gt;Investment company securities risk.&lt;/b&gt; A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;

               &lt;b&gt;Lifecycle risk.&lt;/b&gt; Managers might not correctly predict market or economic conditions, and you could lose money even close to, during, or after the fund's designated retirement year.&lt;/div&gt;

               &lt;b&gt;Target allocation risk.&lt;/b&gt; The fund's risk profile will change due to reallocation or rebalancing of portfolio assets as the fund approaches its target date.&lt;/div&gt;

               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The following information illustrates the variability of the fund's returns and provides some indication of the risks of investing in the fund by showing changes in the fund's performance from year to year and by showing how the fund's average annual returns compared with a broad-based market index. Past performance (before and after taxes) does not indicate future results. All figures assume dividend reinvestment. Performance information is updated daily, monthly, and quarterly and may be obtained at our website, jhinvestments.com, or by calling 800-344-1029 between 8:00 A.M. and 7:00 P.M., Eastern time, on most business days.&lt;/div&gt;

The information shows how the fund's performance compares with the returns of an index of funds with similar investment objectives. From December 1, 2016 to November 30, 2017, the Custom Benchmark consisted of the following indices and approximate weightings: 40.60% Russell 3000 Index, 17.40% MSCI ACWI ex-USA Index, 33.60% Bloomberg Barclays U.S. Aggregate Bond Index, and 8.40% ICE Bank of America Merrill Lynch U.S. High Yield Master II Index. The weightings of the indices in the Custom Benchmark are adjusted annually to reflect changes in the fund's target asset allocation in accordance with the annual roll-down of the glide path described above and differed in periods prior to December 1, 2016.&lt;/div&gt;

The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 11% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund primarily invests its assets in underlying funds using an asset allocation strategy designed for investors expected to retire around the year 2020.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The portfolio managers of the fund allocate assets among the underlying funds according to an asset allocation strategy that becomes increasingly conservative over time. John Hancock Multi-Index 2020 Preservation Portfolio has a target asset allocation of 11.50% of its assets in underlying funds that invest primarily in equity securities. The fund will have a greater exposure to underlying funds that invest primarily in fixed-income securities than will a John Hancock Multi-Index Preservation Portfolio with a more distant target date. To attempt to reduce investment risk and volatility as retirement approaches, the asset allocation strategy will change over time according to a predetermined glide path shown in the following chart.&lt;/div&gt;         
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                  GLIDE PATH CHART               
               &lt;/b&gt;&lt;/div&gt;             
              &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;/div&gt;        
                  &lt;img alt="glidepath chart" src="glidepath2.jpg"&gt;&lt;/img&gt;  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The allocations reflected in the glide path are referred to as neutral because they do not reflect active decisions made by the portfolio managers to produce an overweight or an underweight position in a particular asset class. The fund has a target allocation to underlying funds that invest in the broad asset classes of equity and fixed-income securities but may also allocate its assets to underlying funds that invest outside these asset classes to protect the fund or help it achieve its objective. For example, the fund may also allocate its assets to underlying funds that invest in alternative and specialty asset classes. The investment advisor may change the target allocation without shareholder approval if it believes such change would benefit the fund and its shareholders. There is no guarantee that the managers will correctly predict the market or economic conditions. There is no guarantee that the fund will preserve either income or capital and, as with other mutual fund investments, you could lose money even if the fund is at or close to its designated retirement year. Under normal circumstances, any deviation from the target allocation is not expected to be greater than plus or minus 10%.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is designed for investors who anticipate reevaluating their retirement allocation strategies at the target date. Under normal market conditions, the fund expects to allocate 8% of its assets to equity underlying funds in its designated retirement year and to maintain that static allocation thereafter. This static allocation may be appropriate for some investors, but others may wish to reallocate their investments at retirement.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in underlying funds that invest in a broad range of equity, fixed-income, and alternative/specialty securities and asset classes, including, but not limited to, U.S. and foreign securities, including emerging-market securities, commodities, asset-backed securities, small-cap securities, and below-investment-grade securities (i.e., junk bonds). The underlying funds may also use derivatives, such as swaps, foreign currency forwards, futures, and options, in each case for the purposes of reducing risk, obtaining efficient market exposure and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund will invest in various passively managed underlying funds that as a group hold a wide range of equity-type securities in their portfolios, including convertible securities. The fund may also invest in various actively managed funds. The fund is not designed to track an index or group of indexes. Equity-type securities include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. Certain equity underlying funds may invest in initial public offerings (IPOs). Each of the equity underlying funds has its own investment strategy that, for example, may focus on growth stocks or value stocks, or may employ a strategy combining growth and income stocks, and/or may invest in derivatives such as credit default swaps, foreign currency forwards, interest rate swaps, options on securities, and futures contracts. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from shorter to longer term. The fixed-income underlying funds collectively hold various types of debt instruments such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging market securities). Certain underlying funds may invest in illiquid securities, and certain underlying funds may be non-diversified.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest directly in exchange-traded funds (ETFs), exchange-traded notes (ETNs), the securities of other investment companies, U.S. government securities, and other types of investments such as derivatives, including credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, in each case for the purposes of reducing risk, obtaining efficient market exposure, and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;To the extent legally permitted, the Board of Trustees of the fund may, in its discretion, determine to combine the fund with another fund without shareholder approval if the target allocation of the fund matches the target allocation of the other fund, although there is no assurance that the Board of Trustees will so determine at any point.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund bears its own expenses and, in addition, indirectly bears its proportionate share of the expenses of the underlying funds in which it invests. The fund's performance reflects both the managers' allocation decisions and the performance of the underlying funds.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in fixed-income securities than John Hancock Multi-Index Preservation Portfolios with target dates that are more distant, fixed-income securities risks are more prevalent in this fund than in these other target date funds. In addition to fixed-income securities risk, the fund's other main risk factors are listed in alphabetical order.&lt;/div&gt;

               &lt;/b&gt;&lt;/div&gt;             
                     
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk based on the nature of their support.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;

               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;

               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;

               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Investment company securities risk.&lt;/b&gt; A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;

               &lt;b&gt;Lifecycle risk.&lt;/b&gt; Managers might not correctly predict market or economic conditions, and you could lose money even close to, during, or after the fund's designated retirement year.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Target allocation risk.&lt;/b&gt; The fund's risk profile will change due to reallocation or rebalancing of portfolio assets as the fund approaches its target date.&lt;/div&gt;         
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                &lt;i&gt;  Principal risks of investing in the underlying funds      &lt;/i&gt;         
               &lt;/b&gt;&lt;/div&gt;             
                     
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Short sales risk.&lt;/b&gt; Short sales involve costs and risk. A fund must pay the lender interest on the security it borrows, and the fund will lose money if the price of the security increases between the time of the short sale and the date when the fund replaces the borrowed security.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

The information shows how the fund's performance compares with the returns of an index of funds with similar investment objectives. From December 1, 2016 to November 30, 2017, the Custom Benchmark consisted of the following indices and approximate weightings: 12.60% Russell 3000 Index, 5.40% MSCI ACWI ex-USA Index, and 82.00% Bloomberg Barclays U.S. Aggregate Bond Index. The weightings of the indices in the Custom Benchmark are adjusted annually to reflect changes in the fund's target asset allocation in accordance with the annual roll-down of the glide path described above and differed in periods prior to December 1, 2016.&lt;/div&gt;

The example assumes a 5% average annual return and that fund expenses will not change over the periods.

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 23% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests substantially all of its assets in underlying funds using an asset allocation strategy designed for investors expected to retire around the year 2025.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The portfolio managers of the fund allocate assets among the underlying funds according to an asset allocation strategy that becomes increasingly conservative over time. John Hancock Multi-Index 2025 Lifetime Portfolio has a target asset allocation of 65% of its assets in underlying funds that invest primarily in equity securities. The fund will have a greater exposure to underlying funds that invest primarily in equity securities than will a John Hancock Multi-Index Lifetime Portfolio with a closer target date. To reduce investment risk and volatility as retirement approaches and in the postretirement years, the asset allocation strategy will change over time according to a predetermined "glide path" shown in the following chart. The fund may be a primary source of income for its shareholders after retirement.&lt;/div&gt;         
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                  GLIDE PATH CHART               
               &lt;/b&gt;&lt;/div&gt;      
 &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;/div&gt;       
                      &lt;img alt="glidepath chart" src="glidepath3.jpg"&gt;&lt;/img&gt;  
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The allocations reflected in the glide path are referred to as target allocations because they do not reflect active decisions made by the portfolio managers to produce an overweight or an underweight position in a particular asset class. The fund has a target allocation to underlying funds that invest in the broad asset classes of equity and fixed-income securities, but may also allocate its assets to underlying funds that invest outside these asset classes to protect the fund or help it achieve its objective. For example, the fund may also allocate its assets to underlying funds that invest in alternative and specialty asset classes. The managers may change the target allocation without shareholder approval if they believe that such change would benefit the fund and its shareholders. Under normal circumstances, any deviation from the target allocation is not expected to be greater than plus or minus 10%.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Within the prescribed percentage allocation, the managers select the percentage level to be maintained in specific underlying funds. New investments made by the fund may be directed to particular underlying funds in an effort to maintain the desired target allocations. There is no guarantee that the portfolio managers will correctly predict the market or economic conditions and, as with other mutual fund investments, you could lose money even if the fund is at or close to its designated retirement year or in its postretirement stage.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is designed for investors who may remain invested in the fund through their retirement years. The fund will continue to be managed according to an allocation strategy that becomes increasingly conservative over time until approximately twenty years after retirement, at which time the fund expects to maintain a static allocation of approximately 25% of its assets in equity underlying funds.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in underlying funds that invest in a broad range of equity, fixed-income, and alternative/specialty securities and asset classes, including, but not limited to, U.S. and foreign securities, including emerging-market securities, commodities, asset-backed securities, small-cap securities, and below-investment-grade securities (i.e., junk bonds). The underlying funds may also use derivatives, such as swaps, foreign currency forwards, futures, and options, in each case for the purposes of reducing risk, obtaining efficient market exposure and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund will invest in various passively managed underlying funds that as a group hold a wide range of equity-type securities in their portfolios, including convertible securities. The fund may also invest in various actively managed funds. The fund is not designed to track an index or group of indexes. Equity-type securities include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. Certain equity underlying funds may invest in initial public offerings (IPOs). Each of the equity underlying funds has its own investment strategy that, for example, may focus on growth stocks or value stocks, or may employ a strategy combining growth and income stocks, and/or may invest in derivatives such as credit default swaps, foreign currency forwards, interest rate swaps, options on securities, and futures contracts. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from shorter to longer term. The fixed-income underlying funds collectively hold various types of debt instruments such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging market securities). Certain underlying funds may invest in illiquid securities, and certain underlying funds may be non-diversified.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest directly in exchange-traded funds (ETFs), exchange-traded notes (ETNs), the securities of other investment companies, U.S. government securities, and other types of investments such as derivatives, including credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, in each case for the purposes of reducing risk, obtaining efficient market exposure, and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;To the extent permitted by law, the Board of Trustees of the fund may, in its discretion, determine to combine the fund with another fund without shareholder approval if the target allocation of the fund matches the target allocation of the other fund, although there is no assurance that the Board of Trustees will so determine at any point. The fund bears its own expenses and, in addition, indirectly bears its proportionate share of the expenses of the underlying funds in which it invests. The fund's performance reflects both the managers' allocation decisions and the performance of the underlying funds.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is subject to risks, and you could lose money by investing in the fund. The principal risks of investing in the fund are listed below.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in equity securities than John Hancock Multi-Index Lifetime Portfolios with closer target dates, equity security risks are more prevalent in this fund than in these other target-date funds. In addition to equity securities risk, the fund's other main risk factors are listed in alphabetical order.&lt;/div&gt;

                &lt;i&gt;  Principal risks of investing in the fund of funds  &lt;/i&gt;             
               &lt;/b&gt;&lt;/div&gt;             
                     
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk based on the nature of their support.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Investment company securities risk.&lt;/b&gt; A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lifecycle risk.&lt;/b&gt; Managers might not correctly predict market or economic conditions, and you could lose money even close to, during, or after the fund's designated retirement year.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Target allocation risk.&lt;/b&gt; The fund's risk profile will change due to reallocation or rebalancing of portfolio assets as the fund approaches its target date.&lt;/div&gt;         
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                &lt;i&gt;  Principal risks of investing in the underlying funds  &lt;/i&gt;             
               &lt;/b&gt;&lt;/div&gt;             
                     
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The following information illustrates the variability of the fund's returns and provides some indication of the risks of investing in the fund by showing changes in the fund's performance from year to year and by showing how the fund's average annual returns compared with a broad-based market index. Past performance (before and after taxes) does not indicate future results. All figures assume dividend reinvestment. Performance information is updated daily, monthly, and quarterly and may be obtained at our website, jhinvestments.com, or by calling 800-344-1029 between 8:00 A.M. and 7:00 P.M., Eastern time, on most business days.&lt;/div&gt;

The information shows how the fund's performance compares with the returns of an index of funds with similar investment objectives. From December 1, 2016 to November 30, 2017, the Custom Benchmark consisted of the following indices and approximate weightings: 49.00% Russell 3000 Index, 21.00% MSCI ACWI ex-USA Index, 24.00% Bloomberg Barclays U.S. Aggregate Bond Index, and 6.00% ICE Bank of America Merrill Lynch U.S. High Yield Master II Index.

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 14% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund primarily invests its assets in underlying funds using an asset allocation strategy designed for investors expected to retire around the year 2025.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The portfolio managers of the fund allocate assets among the underlying funds according to an asset allocation strategy that becomes increasingly conservative over time. John Hancock Multi-Index 2025 Preservation Portfolio has a target asset allocation of 32% of its assets in underlying funds that invest primarily in equity securities. The fund will have a greater exposure to underlying funds that invest primarily in fixed-income securities than will a John Hancock Multi-Index Preservation Portfolio with a more distant target date. To attempt to reduce investment risk and volatility as retirement approaches, the asset allocation strategy will change over time according to a predetermined glide path shown in the following chart.&lt;/div&gt;         
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                  GLIDE PATH CHART               
               &lt;/b&gt;&lt;/div&gt;  
 &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;/div&gt;           
                 &lt;img alt="glidepath chart" src="glidepath2.jpg"&gt;&lt;/img&gt;      
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The allocations reflected in the glide path are referred to as neutral because they do not reflect active decisions made by the portfolio managers to produce an overweight or an underweight position in a particular asset class. The fund has a target allocation to underlying funds that invest in the broad asset classes of equity and fixed-income securities but may also allocate its assets to underlying funds that invest outside these asset classes to protect the fund or help it achieve its objective. For example, the fund may also allocate its assets to underlying funds that invest in alternative and specialty asset classes. The investment advisor may change the target allocation without shareholder approval if it believes such change would benefit the fund and its shareholders. There is no guarantee that the managers will correctly predict the market or economic conditions. There is no guarantee that the fund will preserve either income or capital and, as with other mutual fund investments, you could lose money even if the fund is at or close to its designated retirement year. Under normal circumstances, any deviation from the target allocation is not expected to be greater than plus or minus 10%.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is designed for investors who anticipate reevaluating their retirement allocation strategies at the target date. Under normal market conditions, the fund expects to allocate 8% of its assets to equity underlying funds in its designated retirement year and to maintain that static allocation thereafter. This static allocation may be appropriate for some investors, but others may wish to reallocate their investments at retirement.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in underlying funds that invest in a broad range of equity, fixed-income, and alternative/specialty securities and asset classes, including, but not limited to, U.S. and foreign securities, including emerging-market securities, commodities, asset-backed securities, small-cap securities, and below-investment-grade securities (i.e., junk bonds). The underlying funds may also use derivatives, such as swaps, foreign currency forwards, futures, and options, in each case for the purposes of reducing risk, obtaining efficient market exposure and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund will invest in various passively managed underlying funds that as a group hold a wide range of equity-type securities in their portfolios, including convertible securities. The fund may also invest in various actively managed funds. The fund is not designed to track an index or group of indexes. Equity-type securities include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. Certain equity underlying funds may invest in initial public offerings (IPOs). Each of the equity underlying funds has its own investment strategy that, for example, may focus on growth stocks or value stocks, or may employ a strategy combining growth and income stocks, and/or may invest in derivatives such as credit default swaps, foreign currency forwards, interest rate swaps, options on securities, and futures contracts. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from shorter to longer term. The fixed-income underlying funds collectively hold various types of debt instruments such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging market securities). Certain underlying funds may invest in illiquid securities, and certain underlying funds may be non-diversified.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest directly in exchange-traded funds (ETFs), exchange-traded notes (ETNs), the securities of other investment companies, U.S. government securities, and other types of investments such as derivatives, including credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, in each case for the purposes of reducing risk, obtaining efficient market exposure, and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;To the extent legally permitted, the Board of Trustees of the fund may, in its discretion, determine to combine the fund with another fund without shareholder approval if the target allocation of the fund matches the target allocation of the other fund, although there is no assurance that the Board of Trustees will so determine at any point.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund bears its own expenses and, in addition, indirectly bears its proportionate share of the expenses of the underlying funds in which it invests. The fund's performance reflects both the managers' allocation decisions and the performance of the underlying funds.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is subject to risks, and you could lose money by investing in the fund. The principal risks of investing in the fund are listed below.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in fixed-income securities than John Hancock Multi-Index Preservation Portfolios with target dates that are more distant, fixed-income securities risks are more prevalent in this fund than in these other target date funds. In addition to fixed-income securities risk, the fund's other main risk factors are listed in alphabetical order.&lt;/div&gt;

               &lt;i&gt;   Principal risks of investing in the fund of funds   &lt;/i&gt;            
               &lt;/b&gt;&lt;/div&gt;             
                     
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk based on the nature of their support.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Investment company securities risk.&lt;/b&gt; A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lifecycle risk.&lt;/b&gt; Managers might not correctly predict market or economic conditions, and you could lose money even close to, during, or after the fund's designated retirement year.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Target allocation risk.&lt;/b&gt; The fund's risk profile will change due to reallocation or rebalancing of portfolio assets as the fund approaches its target date.&lt;/div&gt;

               &lt;i&gt;   Principal risks of investing in the underlying funds   &lt;/i&gt;            
               &lt;/b&gt;&lt;/div&gt;             
                     
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Short sales risk.&lt;/b&gt; Short sales involve costs and risk. A fund must pay the lender interest on the security it borrows, and the fund will lose money if the price of the security increases between the time of the short sale and the date when the fund replaces the borrowed security.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The following information illustrates the variability of the fund's returns and provides some indication of the risks of investing in the fund by showing changes in the fund's performance from year to year and by showing how the fund's average annual returns compared with a broad-based market index. Past performance (before and after taxes) does not indicate future results. All figures assume dividend reinvestment. Performance information is updated daily, monthly, and quarterly and may be obtained at our website, jhinvestments.com, or by calling 800-344-1029 between 8:00 A.M. and 7:00 P.M., Eastern time, on most business days.&lt;/div&gt;

               &lt;b&gt;Russell 3000 Index/MSCI ACWI ex-USA Index/Bloomberg Barclays U.S. Aggregate Bond Index&lt;/b&gt; This custom blended benchmark (Custom Benchmark) is based on the fund's asset allocation glide path shown above and will reflect a more conservative asset allocation over time. The information shows how the fund's performance compares with the returns of an index of funds with similar investment objectives. From December 1, 2016 to November 30, 2017, the Custom Benchmark consisted of the following indices and approximate weightings: 28.00% Russell 3000 Index, 12.00% MSCI ACWI ex-USA Index, and 60.00% Bloomberg Barclays U.S. Aggregate Bond Index. The weightings of the indices in the Custom Benchmark are adjusted annually to reflect changes in the fund's target asset allocation in accordance with the annual roll-down of the glide path described above and differed in periods prior to December 1, 2016.&lt;/div&gt;

Your actual after-tax returns may be different. After-tax returns are not relevant to shares held in an IRA, 401(k), or other tax-advantaged investment plan.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 19% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The portfolio managers of the fund allocate assets among the underlying funds according to an asset allocation strategy that becomes increasingly conservative over time. John Hancock Multi-Index 2030 Lifetime Portfolio has a target asset allocation of 77% of its assets in underlying funds that invest primarily in equity securities. The fund will have a greater exposure to underlying funds that invest primarily in equity securities than will a John Hancock Multi-Index Lifetime Portfolio with a closer target date. To reduce investment risk and volatility as retirement approaches and in the postretirement years, the asset allocation strategy will change over time according to a predetermined "glide path" shown in the following chart. The fund may be a primary source of income for its shareholders after retirement.&lt;/div&gt;         
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                  GLIDE PATH CHART               
               &lt;/b&gt;&lt;/div&gt;             
           &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;/div&gt;           
                   &lt;img alt="glidepath chart" src="glidepath3.jpg"&gt;&lt;/img&gt;  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The allocations reflected in the glide path are referred to as target allocations because they do not reflect active decisions made by the portfolio managers to produce an overweight or an underweight position in a particular asset class. The fund has a target allocation to underlying funds that invest in the broad asset classes of equity and fixed-income securities, but may also allocate its assets to underlying funds that invest outside these asset classes to protect the fund or help it achieve its objective. For example, the fund may also allocate its assets to underlying funds that invest in alternative and specialty asset classes. The managers may change the target allocation without shareholder approval if they believe that such change would benefit the fund and its shareholders. Under normal circumstances, any deviation from the target allocation is not expected to be greater than plus or minus 10%.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Within the prescribed percentage allocation, the managers select the percentage level to be maintained in specific underlying funds. New investments made by the fund may be directed to particular underlying funds in an effort to maintain the desired target allocations. There is no guarantee that the portfolio managers will correctly predict the market or economic conditions and, as with other mutual fund investments, you could lose money even if the fund is at or close to its designated retirement year or in its postretirement stage.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is designed for investors who may remain invested in the fund through their retirement years. The fund will continue to be managed according to an allocation strategy that becomes increasingly conservative over time until approximately twenty years after retirement, at which time the fund expects to maintain a static allocation of approximately 25% of its assets in equity underlying funds.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in underlying funds that invest in a broad range of equity, fixed-income, and alternative/specialty securities and asset classes, including, but not limited to, U.S. and foreign securities, including emerging-market securities, commodities, asset-backed securities, small-cap securities, and below-investment-grade securities (i.e., junk bonds). The underlying funds may also use derivatives, such as swaps, foreign currency forwards, futures, and options, in each case for the purposes of reducing risk, obtaining efficient market exposure and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund will invest in various passively managed underlying funds that as a group hold a wide range of equity-type securities in their portfolios, including convertible securities. The fund may also invest in various actively managed funds. The fund is not designed to track an index or group of indexes. Equity-type securities include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. Certain equity underlying funds may invest in initial public offerings (IPOs). Each of the equity underlying funds has its own investment strategy that, for example, may focus on growth stocks or value stocks, or may employ a strategy combining growth and income stocks, and/or may invest in derivatives such as credit default swaps, foreign currency forwards, interest rate swaps, options on securities, and futures contracts. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from shorter to longer term. The fixed-income underlying funds collectively hold various types of debt instruments such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging market securities). Certain underlying funds may invest in illiquid securities, and certain underlying funds may be non-diversified.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest directly in exchange-traded funds (ETFs), exchange-traded notes (ETNs), the securities of other investment companies, U.S. government securities, and other types of investments such as derivatives, including credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, in each case for the purposes of reducing risk, obtaining efficient market exposure, and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;To the extent permitted by law, the Board of Trustees of the fund may, in its discretion, determine to combine the fund with another fund without shareholder approval if the target allocation of the fund matches the target allocation of the other fund, although there is no assurance that the Board of Trustees will so determine at any point. The fund bears its own expenses and, in addition, indirectly bears its proportionate share of the expenses of the underlying funds in which it invests. The fund's performance reflects both the managers' allocation decisions and the performance of the underlying funds.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is subject to risks, and you could lose money by investing in the fund. The principal risks of investing in the fund are listed below.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in equity securities than John Hancock Multi-Index Lifetime Portfolios with closer target dates, equity security risks are more prevalent in this fund than in these other target-date funds. In addition to equity securities risk, the fund's other main risk factors are listed in alphabetical order.&lt;/div&gt;

                &lt;i&gt;  Principal risks of investing in the fund of funds  &lt;/i&gt;             
               &lt;/b&gt;&lt;/div&gt;             
                     
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk based on the nature of their support.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Investment company securities risk.&lt;/b&gt; A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;

               &lt;b&gt;Lifecycle risk.&lt;/b&gt; Managers might not correctly predict market or economic conditions, and you could lose money even close to, during, or after the fund's designated retirement year.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Target allocation risk.&lt;/b&gt; The fund's risk profile will change due to reallocation or rebalancing of portfolio assets as the fund approaches its target date.&lt;/div&gt;         
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                &lt;i&gt;  Principal risks of investing in the underlying funds               
               &lt;/i&gt;&lt;/b&gt;&lt;/div&gt;             
                     
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;

               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;

               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;

               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;

               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;

               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;

               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;

Past performance (before and after taxes) does not indicate future results. All figures assume dividend reinvestment. Performance information is updated daily, monthly, and quarterly and may be obtained at our website, jhinvestments.com, or by calling 800-344-1029 between 8:00 A.M. and 7:00 P.M., Eastern time, on most business days.&lt;/div&gt;

The information shows how the fund's performance compares with the returns of an index of funds with similar investment objectives. From December 1, 2016 to November 30, 2017, the Custom Benchmark consisted of the following indices and approximate weightings: 56.70% Russell 3000 Index, 24.30% MSCI ACWI ex-USA Index, 15.20% Bloomberg Barclays U.S. Aggregate Bond Index, and 3.80% ICE Bank of America Merrill Lynch U.S. High Yield Master II Index. The weightings of the indices in the Custom Benchmark are adjusted annually to reflect changes in the fund's target asset allocation in accordance with the annual roll-down of the glide path described above and differed in periods prior to December 1, 2016.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 18% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund primarily invests its assets in underlying funds using an asset allocation strategy designed for investors expected to retire around the year 2030.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The portfolio managers of the fund allocate assets among the underlying funds according to an asset allocation strategy that becomes increasingly conservative over time. John Hancock Multi-Index 2030 Preservation Portfolio has a target asset allocation of 51.50% of its assets in underlying funds that invest primarily in equity securities. The fund will have a greater exposure to underlying funds that invest primarily in equity securities than will a John Hancock Multi-Index Preservation Portfolio with a closer target date. To attempt to reduce investment risk and volatility as retirement approaches, the asset allocation strategy will change over time according to a predetermined glide path shown in the following chart.&lt;/div&gt;         
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                  GLIDE PATH CHART               
               &lt;/b&gt;&lt;/div&gt;   
 &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;/div&gt;          
                   &lt;img alt="glidepath chart" src="glidepath2.jpg"&gt;&lt;/img&gt;    
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The allocations reflected in the glide path are referred to as neutral because they do not reflect active decisions made by the portfolio managers to produce an overweight or an underweight position in a particular asset class. The fund has a target allocation to underlying funds that invest in the broad asset classes of equity and fixed-income securities but may also allocate its assets to underlying funds that invest outside these asset classes to protect the fund or help it achieve its objective. For example, the fund may also allocate its assets to underlying funds that invest in alternative and specialty asset classes. The investment advisor may change the target allocation without shareholder approval if it believes such change would benefit the fund and its shareholders. There is no guarantee that the managers will correctly predict the market or economic conditions. There is no guarantee that the fund will preserve either income or capital and, as with other mutual fund investments, you could lose money even if the fund is at or close to its designated retirement year. Under normal circumstances, any deviation from the target allocation is not expected to be greater than plus or minus 10%.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is designed for investors who anticipate reevaluating their retirement allocation strategies at the target date. Under normal market conditions, the fund expects to allocate 8% of its assets to equity underlying funds in its designated retirement year and to maintain that static allocation thereafter. This static allocation may be appropriate for some investors, but others may wish to reallocate their investments at retirement.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in underlying funds that invest in a broad range of equity, fixed-income, and alternative/specialty securities and asset classes, including, but not limited to, U.S. and foreign securities, including emerging-market securities, commodities, asset-backed securities, small-cap securities, and below-investment-grade securities (i.e., junk bonds). The underlying funds may also use derivatives, such as swaps, foreign currency forwards, futures, and options, in each case for the purposes of reducing risk, obtaining efficient market exposure and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund will invest in various passively managed underlying funds that as a group hold a wide range of equity-type securities in their portfolios, including convertible securities. The fund may also invest in various actively managed funds. The fund is not designed to track an index or group of indexes. Equity-type securities include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. Certain equity underlying funds may invest in initial public offerings (IPOs). Each of the equity underlying funds has its own investment strategy that, for example, may focus on growth stocks or value stocks, or may employ a strategy combining growth and income stocks, and/or may invest in derivatives such as credit default swaps, foreign currency forwards, interest rate swaps, options on securities, and futures contracts. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from shorter to longer term. The fixed-income underlying funds collectively hold various types of debt instruments such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging market securities). Certain underlying funds may invest in illiquid securities, and certain underlying funds may be non-diversified.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest directly in exchange-traded funds (ETFs), exchange-traded notes (ETNs), the securities of other investment companies, U.S. government securities, and other types of investments such as derivatives, including credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, in each case for the purposes of reducing risk, obtaining efficient market exposure, and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;To the extent legally permitted, the Board of Trustees of the fund may, in its discretion, determine to combine the fund with another fund without shareholder approval if the target allocation of the fund matches the target allocation of the other fund, although there is no assurance that the Board of Trustees will so determine at any point.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund bears its own expenses and, in addition, indirectly bears its proportionate share of the expenses of the underlying funds in which it invests. The fund's performance reflects both the managers' allocation decisions and the performance of the underlying funds.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is subject to risks, and you could lose money by investing in the fund.  The principal risks of investing in the fund are listed below.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in equity securities than John Hancock Multi-Index Preservation Portfolios with closer target dates, equity security risks are more prevalent in this fund than in these other target-date funds. In addition to equity securities risk, the fund's other main risk factors are listed in alphabetical order.&lt;/div&gt;         
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                 &lt;i&gt; Principal risks of investing in the fund of funds  &lt;/i&gt;             
               &lt;/b&gt;&lt;/div&gt;             
                     
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk based on the nature of their support.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Investment company securities risk.&lt;/b&gt; A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lifecycle risk.&lt;/b&gt; Managers might not correctly predict market or economic conditions, and you could lose money even close to, during, or after the fund's designated retirement year.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Target allocation risk.&lt;/b&gt; The fund's risk profile will change due to reallocation or rebalancing of portfolio assets as the fund approaches its target date.&lt;/div&gt;         
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
               &lt;i&gt;   Principal risks of investing in the underlying funds   &lt;/i&gt;            
               &lt;/b&gt;&lt;/div&gt;             
                     
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;

               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;

               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;

               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;

               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;

               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Short sales risk.&lt;/b&gt; Short sales involve costs and risk. A fund must pay the lender interest on the security it borrows, and the fund will lose money if the price of the security increases between the time of the short sale and the date when the fund replaces the borrowed security.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

Past performance (before and after taxes) does not indicate future results. All figures assume dividend reinvestment. Performance information is updated daily, monthly, and quarterly and may be obtained at our website, jhinvestments.com, or by calling 800-344-1029 between 8:00 A.M. and 7:00 P.M., Eastern time, on most business days.&lt;/div&gt;

The information shows how the fund's performance compares with the returns of an index of funds with similar investment objectives. From December 1, 2016 to November 30, 2017, the Custom Benchmark consisted of the following indices and approximate weightings: 41.30% Russell 3000 Index, 17.70% MSCI ACWI ex-USA Index, and 41.00% Bloomberg Barclays U.S. Aggregate Bond Index. The weightings of the indices in the Custom Benchmark are adjusted annually to reflect changes in the fund's target asset allocation in accordance with the annual roll-down of the glide path described above and differed in periods prior to December 1, 2016.&lt;/div&gt;

Please see below a hypothetical example showing the expenses of a $10,000 investment for the time periods indicated and then assuming you sell all of your shares at the end of those periods. The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 15% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests substantially all of its assets in underlying funds using an asset allocation strategy designed for investors expected to retire around the year 2035.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The portfolio managers of the fund allocate assets among the underlying funds according to an asset allocation strategy that becomes increasingly conservative over time. John Hancock Multi-Index 2035 Lifetime Portfolio has a target asset allocation of 86% of its assets in underlying funds that invest primarily in equity securities. The fund will have a greater exposure to underlying funds that invest primarily in equity securities than will a John Hancock Multi-Index Lifetime Portfolio with a closer target date. To reduce investment risk and volatility as retirement approaches and in the postretirement years, the asset allocation strategy will change over time according to a predetermined "glide path" shown in the following chart. The fund may be a primary source of income for its shareholders after retirement.&lt;/div&gt;         
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                  GLIDE PATH CHART               
               &lt;/b&gt;&lt;/div&gt;             
              &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;/div&gt;        
                   &lt;img alt="glidepath chart" src="glidepath3.jpg"&gt;&lt;/img&gt;  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The allocations reflected in the glide path are referred to as target allocations because they do not reflect active decisions made by the portfolio managers to produce an overweight or an underweight position in a particular asset class. The fund has a target allocation to underlying funds that invest in the broad asset classes of equity and fixed-income securities, but may also allocate its assets to underlying funds that invest outside these asset classes to protect the fund or help it achieve its objective. For example, the fund may also allocate its assets to underlying funds that invest in alternative and specialty asset classes. The managers may change the target allocation without shareholder approval if they believe that such change would benefit the fund and its shareholders. Under normal circumstances, any deviation from the target allocation is not expected to be greater than plus or minus 10%.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Within the prescribed percentage allocation, the managers select the percentage level to be maintained in specific underlying funds. New investments made by the fund may be directed to particular underlying funds in an effort to maintain the desired target allocations. There is no guarantee that the portfolio managers will correctly predict the market or economic conditions and, as with other mutual fund investments, you could lose money even if the fund is at or close to its designated retirement year or in its postretirement stage.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is designed for investors who may remain invested in the fund through their retirement years. The fund will continue to be managed according to an allocation strategy that becomes increasingly conservative over time until approximately twenty years after retirement, at which time the fund expects to maintain a static allocation of approximately 25% of its assets in equity underlying funds.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in underlying funds that invest in a broad range of equity, fixed-income, and alternative/specialty securities and asset classes, including, but not limited to, U.S. and foreign securities, including emerging-market securities, commodities, asset-backed securities, small-cap securities, and below-investment-grade securities (i.e., junk bonds). The underlying funds may also use derivatives, such as swaps, foreign currency forwards, futures, and options, in each case for the purposes of reducing risk, obtaining efficient market exposure and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund will invest in various passively managed underlying funds that as a group hold a wide range of equity-type securities in their portfolios, including convertible securities. The fund may also invest in various actively managed funds. The fund is not designed to track an index or group of indexes. Equity-type securities include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. Certain equity underlying funds may invest in initial public offerings (IPOs). Each of the equity underlying funds has its own investment strategy that, for example, may focus on growth stocks or value stocks, or may employ a strategy combining growth and income stocks, and/or may invest in derivatives such as credit default swaps, foreign currency forwards, interest rate swaps, options on securities, and futures contracts. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from shorter to longer term. The fixed-income underlying funds collectively hold various types of debt instruments such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging market securities). Certain underlying funds may invest in illiquid securities, and certain underlying funds may be non-diversified.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest directly in exchange-traded funds (ETFs), exchange-traded notes (ETNs), the securities of other investment companies, U.S. government securities, and other types of investments such as derivatives, including credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, in each case for the purposes of reducing risk, obtaining efficient market exposure, and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;To the extent permitted by law, the Board of Trustees of the fund may, in its discretion, determine to combine the fund with another fund without shareholder approval if the target allocation of the fund matches the target allocation of the other fund, although there is no assurance that the Board of Trustees will so determine at any point. The fund bears its own expenses and, in addition, indirectly bears its proportionate share of the expenses of the underlying funds in which it invests. The fund's performance reflects both the managers' allocation decisions and the performance of the underlying funds.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is subject to risks, and you could lose money by investing in the fund. The principal risks of investing in the fund are listed below.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in equity securities than John Hancock Multi-Index Lifetime Portfolios with closer target dates, equity security risks are more prevalent in this fund than in these other target-date funds. In addition to equity securities risk, the fund's other main risk factors are listed in alphabetical order.&lt;/div&gt;          
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                 &lt;i&gt; Principal risks of investing in the fund of funds &lt;/i&gt;              
               &lt;/b&gt;&lt;/div&gt;             
                     
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk based on the nature of their support.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;

               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;

               &lt;b&gt;Lifecycle risk.&lt;/b&gt; Managers might not correctly predict market or economic conditions, and you could lose money even close to, during, or after the fund's designated retirement year.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Target allocation risk.&lt;/b&gt; The fund's risk profile will change due to reallocation or rebalancing of portfolio assets as the fund approaches its target date.&lt;/div&gt;

               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;

               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The following information illustrates the variability of the fund's returns and provides some indication of the risks of investing in the fund by showing changes in the fund's performance from year to year and by showing how the fund's average annual returns compared with a broad-based market index. Past performance (before and after taxes) does not indicate future results. All figures assume dividend reinvestment. Performance information is updated daily, monthly, and quarterly and may be obtained at our website, jhinvestments.com, or by calling 800-344-1029 between 8:00 A.M. and 7:00 P.M., Eastern time, on most business days.&lt;/div&gt;

The information shows how the fund's performance compares with the returns of an index of funds with similar investment objectives. From December 1, 2016 to November 30, 2017, the Custom Benchmark consisted of the following indices and approximate weightings: 62.30% Russell 3000 Index, 26.70% MSCI ACWI ex-USA Index, 8.80% Bloomberg Barclays U.S. Aggregate Bond Index, and 2.20% ICE Bank of America Merrill Lynch U.S. High Yield Master II Index. The weightings of the indices in the Custom Benchmark are adjusted annually to reflect changes in the fund's target asset allocation in accordance with the annual roll-down of the glide path described above and differed in periods prior to December 1, 2016.&lt;/div&gt;

They are based on expenses incurred during the fund's most recent fiscal year expressed as a percentage of the fund's average net assets during the year. The fees and expenses do not reflect fees and expenses of any separate account that may use the fund as its underlying investment option and would be higher if they did.&lt;/div&gt;

Please see below a hypothetical example showing the expenses of a $10,000 investment for the time periods indicated and then assuming you sell all of your shares at the end of those periods. The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 17% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund primarily invests its assets in underlying funds using an asset allocation strategy designed for investors expected to retire around the year 2035.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The portfolio managers of the fund allocate assets among the underlying funds according to an asset allocation strategy that becomes increasingly conservative over time. John Hancock Multi-Index 2035 Preservation Portfolio has a target asset allocation of 67% of its assets in underlying funds that invest primarily in equity securities. The fund will have a greater exposure to underlying funds that invest primarily in equity securities than will a John Hancock Multi-Index Preservation Portfolio with a closer target date. To attempt to reduce investment risk and volatility as retirement approaches, the asset allocation strategy will change over time according to a predetermined glide path shown in the following chart.&lt;/div&gt;         
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                  GLIDE PATH CHART               
               &lt;/b&gt;&lt;/div&gt;
 &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;/div&gt;             
                    &lt;img alt="glidepath chart" src="glidepath2.jpg"&gt;&lt;/img&gt;   
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The allocations reflected in the glide path are referred to as neutral because they do not reflect active decisions made by the portfolio managers to produce an overweight or an underweight position in a particular asset class. The fund has a target allocation to underlying funds that invest in the broad asset classes of equity and fixed-income securities but may also allocate its assets to underlying funds that invest outside these asset classes to protect the fund or help it achieve its objective. For example, the fund may also allocate its assets to underlying funds that invest in alternative and specialty asset classes. The investment advisor may change the target allocation without shareholder approval if it believes such change would benefit the fund and its shareholders. There is no guarantee that the managers will correctly predict the market or economic conditions. There is no guarantee that the fund will preserve either income or capital and, as with other mutual fund investments, you could lose money even if the fund is at or close to its designated retirement year. Under normal circumstances, any deviation from the target allocation is not expected to be greater than plus or minus 10%.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is designed for investors who anticipate reevaluating their retirement allocation strategies at the target date. Under normal market conditions, the fund expects to allocate 8% of its assets to equity underlying funds in its designated retirement year and to maintain that static allocation thereafter. This static allocation may be appropriate for some investors, but others may wish to reallocate their investments at retirement.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in underlying funds that invest in a broad range of equity, fixed-income, and alternative/specialty securities and asset classes, including, but not limited to, U.S. and foreign securities, including emerging-market securities, commodities, asset-backed securities, small-cap securities, and below-investment-grade securities (i.e., junk bonds). The underlying funds may also use derivatives, such as swaps, foreign currency forwards, futures, and options, in each case for the purposes of reducing risk, obtaining efficient market exposure and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund will invest in various passively managed underlying funds that as a group hold a wide range of equity-type securities in their portfolios, including convertible securities. The fund may also invest in various actively managed funds. The fund is not designed to track an index or group of indexes. Equity-type securities include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. Certain equity underlying funds may invest in initial public offerings (IPOs). Each of the equity underlying funds has its own investment strategy that, for example, may focus on growth stocks or value stocks, or may employ a strategy combining growth and income stocks, and/or may invest in derivatives such as credit default swaps, foreign currency forwards, interest rate swaps, options on securities, and futures contracts. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from shorter to longer term. The fixed-income underlying funds collectively hold various types of debt instruments such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging market securities). Certain underlying funds may invest in illiquid securities, and certain underlying funds may be non-diversified.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest directly in exchange-traded funds (ETFs), exchange-traded notes (ETNs), the securities of other investment companies, U.S. government securities, and other types of investments such as derivatives, including credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, in each case for the purposes of reducing risk, obtaining efficient market exposure, and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;To the extent legally permitted, the Board of Trustees of the fund may, in its discretion, determine to combine the fund with another fund without shareholder approval if the target allocation of the fund matches the target allocation of the other fund, although there is no assurance that the Board of Trustees will so determine at any point.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund bears its own expenses and, in addition, indirectly bears its proportionate share of the expenses of the underlying funds in which it invests. The fund's performance reflects both the managers' allocation decisions and the performance of the underlying funds.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in equity securities than John Hancock Multi-Index Preservation Portfolios with closer target dates, equity security risks are more prevalent in this fund than in these other target-date funds. In addition to equity securities risk, the fund's other main risk factors are listed in alphabetical order.&lt;/div&gt;         
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                 &lt;i&gt; Principal risks of investing in the fund of funds &lt;/i&gt;              
               &lt;/b&gt;&lt;/div&gt;             
                     
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk based on the nature of their support.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;

               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;

               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Short sales risk.&lt;/b&gt; Short sales involve costs and risk. A fund must pay the lender interest on the security it borrows, and the fund will lose money if the price of the security increases between the time of the short sale and the date when the fund replaces the borrowed security.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The following information illustrates the variability of the fund's returns and provides some indication of the risks of investing in the fund by showing changes in the fund's performance from year to year and by showing how the fund's average annual returns compared with a broad-based market index. Past performance (before and after taxes) does not indicate future results. All figures assume dividend reinvestment. Performance information is updated daily, monthly, and quarterly and may be obtained at our website, jhinvestments.com, or by calling 800-344-1029 between 8:00 A.M. and 7:00 P.M., Eastern time, on most business days.&lt;/div&gt;

The information shows how the fund's performance compares with the returns of an index of funds with similar investment objectives. From December 1, 2016 to November 30, 2017, the Custom Benchmark consisted of the following indices and approximate weightings: 49.70% Russell 3000 Index, 21.30% MSCI ACWI ex-USA Index, and 29.00% Bloomberg Barclays U.S. Aggregate Bond Index. The weightings of the indices in the Custom Benchmark are adjusted annually to reflect changes in the fund's target asset allocation in accordance with the annual roll-down of the glide path described above and differed in periods prior to December 1, 2016.&lt;/div&gt;

The example assumes a 5% average annual return and that fund expenses will not change over the periods.

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 15% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests substantially all of its assets in underlying funds using an asset allocation strategy designed for investors expected to retire around the year 2040.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The portfolio managers of the fund allocate assets among the underlying funds according to an asset allocation strategy that becomes increasingly conservative over time. John Hancock Multi-Index 2040 Lifetime Portfolio has a target asset allocation of 93% of its assets in underlying funds that invest primarily in equity securities. The fund will have a greater exposure to underlying funds that invest primarily in equity securities than will a John Hancock Multi-Index Lifetime Portfolio with a closer target date. To reduce investment risk and volatility as retirement approaches and in the postretirement years, the asset allocation strategy will change over time according to a predetermined "glide path" shown in the following chart. The fund may be a primary source of income for its shareholders after retirement.&lt;/div&gt;         
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                  GLIDE PATH CHART               
               &lt;/b&gt;&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;/div&gt;          
                   &lt;img alt="glidepath chart" src="glidepath3.jpg"&gt;&lt;/img&gt;  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The allocations reflected in the glide path are referred to as target allocations because they do not reflect active decisions made by the portfolio managers to produce an overweight or an underweight position in a particular asset class. The fund has a target allocation to underlying funds that invest in the broad asset classes of equity and fixed-income securities, but may also allocate its assets to underlying funds that invest outside these asset classes to protect the fund or help it achieve its objective. For example, the fund may also allocate its assets to underlying funds that invest in alternative and specialty asset classes. The managers may change the target allocation without shareholder approval if they believe that such change would benefit the fund and its shareholders. Under normal circumstances, any deviation from the target allocation is not expected to be greater than plus or minus 10%.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Within the prescribed percentage allocation, the managers select the percentage level to be maintained in specific underlying funds. New investments made by the fund may be directed to particular underlying funds in an effort to maintain the desired target allocations. There is no guarantee that the portfolio managers will correctly predict the market or economic conditions and, as with other mutual fund investments, you could lose money even if the fund is at or close to its designated retirement year or in its postretirement stage.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is designed for investors who may remain invested in the fund through their retirement years. The fund will continue to be managed according to an allocation strategy that becomes increasingly conservative over time until approximately twenty years after retirement, at which time the fund expects to maintain a static allocation of approximately 25% of its assets in equity underlying funds.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in underlying funds that invest in a broad range of equity, fixed-income, and alternative/specialty securities and asset classes, including, but not limited to, U.S. and foreign securities, including emerging-market securities, commodities, asset-backed securities, small-cap securities, and below-investment-grade securities (i.e., junk bonds). The underlying funds may also use derivatives, such as swaps, foreign currency forwards, futures, and options, in each case for the purposes of reducing risk, obtaining efficient market exposure and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund will invest in various passively managed underlying funds that as a group hold a wide range of equity-type securities in their portfolios, including convertible securities. The fund may also invest in various actively managed funds. The fund is not designed to track an index or group of indexes. Equity-type securities include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. Certain equity underlying funds may invest in initial public offerings (IPOs). Each of the equity underlying funds has its own investment strategy that, for example, may focus on growth stocks or value stocks, or may employ a strategy combining growth and income stocks, and/or may invest in derivatives such as credit default swaps, foreign currency forwards, interest rate swaps, options on securities, and futures contracts. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from shorter to longer term. The fixed-income underlying funds collectively hold various types of debt instruments such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging market securities). Certain underlying funds may invest in illiquid securities, and certain underlying funds may be non-diversified.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest directly in exchange-traded funds (ETFs), exchange-traded notes (ETNs), the securities of other investment companies, U.S. government securities, and other types of investments such as derivatives, including credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, in each case for the purposes of reducing risk, obtaining efficient market exposure, and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;To the extent permitted by law, the Board of Trustees of the fund may, in its discretion, determine to combine the fund with another fund without shareholder approval if the target allocation of the fund matches the target allocation of the other fund, although there is no assurance that the Board of Trustees will so determine at any point. The fund bears its own expenses and, in addition, indirectly bears its proportionate share of the expenses of the underlying funds in which it invests. The fund's performance reflects both the managers' allocation decisions and the performance of the underlying funds.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in equity securities than John Hancock Multi-Index Lifetime Portfolios with closer target dates, equity security risks are more prevalent in this fund than in these other target-date funds. In addition to equity securities risk, the fund's other main risk factors are listed in alphabetical order.&lt;/div&gt;

               &lt;/b&gt;&lt;/div&gt;             
                     
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk based on the nature of their support.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;

               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;

               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Investment company securities risk.&lt;/b&gt; A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;

               &lt;b&gt;Lifecycle risk.&lt;/b&gt; Managers might not correctly predict market or economic conditions, and you could lose money even close to, during, or after the fund's designated retirement year.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Target allocation risk.&lt;/b&gt; The fund's risk profile will change due to reallocation or rebalancing of portfolio assets as the fund approaches its target date.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

The information shows how the fund's performance compares with the returns of an index of funds with similar investment objectives. From November 7, 2013 to November 30, 2017, the Custom Benchmark consisted of the following indices and approximate weightings: 66.50% Russell 3000 Index, 28.50% MSCI ACWI ex-USA Index, 4.00% Bloomberg Barclays U.S. Aggregate Bond Index, and 1.00% ICE Bank of America Merrill Lynch U.S. High Yield Master II Index. The weightings of the indices in the Custom Benchmark are adjusted annually to reflect changes in the fund's target asset allocation in accordance with the annual roll-down of the glide path described above.&lt;/div&gt;

The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 16% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund primarily invests its assets in underlying funds using an asset allocation strategy designed for investors expected to retire around the year 2040.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The portfolio managers of the fund allocate assets among the underlying funds according to an asset allocation strategy that becomes increasingly conservative over time. John Hancock Multi-Index 2040 Preservation Portfolio has a target asset allocation of 75.50% of its assets in underlying funds that invest primarily in equity securities. The fund will have a greater exposure to underlying funds that invest primarily in equity securities than will a John Hancock Multi-Index Preservation Portfolio with a closer target date. To attempt to reduce investment risk and volatility as retirement approaches, the asset allocation strategy will change over time according to a predetermined glide path shown in the following chart.&lt;/div&gt;         
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                  GLIDE PATH CHART               
               &lt;/b&gt;&lt;/div&gt;             
              &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;/div&gt;        
                  &lt;img alt="glidepath chart" src="glidepath2.jpg"&gt;&lt;/img&gt;  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The allocations reflected in the glide path are referred to as neutral because they do not reflect active decisions made by the portfolio managers to produce an overweight or an underweight position in a particular asset class. The fund has a target allocation to underlying funds that invest in the broad asset classes of equity and fixed-income securities but may also allocate its assets to underlying funds that invest outside these asset classes to protect the fund or help it achieve its objective. For example, the fund may also allocate its assets to underlying funds that invest in alternative and specialty asset classes. The investment advisor may change the target allocation without shareholder approval if it believes such change would benefit the fund and its shareholders. There is no guarantee that the managers will correctly predict the market or economic conditions. There is no guarantee that the fund will preserve either income or capital and, as with other mutual fund investments, you could lose money even if the fund is at or close to its designated retirement year. Under normal circumstances, any deviation from the target allocation is not expected to be greater than plus or minus 10%.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is designed for investors who anticipate reevaluating their retirement allocation strategies at the target date. Under normal market conditions, the fund expects to allocate 8% of its assets to equity underlying funds in its designated retirement year and to maintain that static allocation thereafter. This static allocation may be appropriate for some investors, but others may wish to reallocate their investments at retirement.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in underlying funds that invest in a broad range of equity, fixed-income, and alternative/specialty securities and asset classes, including, but not limited to, U.S. and foreign securities, including emerging-market securities, commodities, asset-backed securities, small-cap securities, and below-investment-grade securities (i.e., junk bonds). The underlying funds may also use derivatives, such as swaps, foreign currency forwards, futures, and options, in each case for the purposes of reducing risk, obtaining efficient market exposure and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund will invest in various passively managed underlying funds that as a group hold a wide range of equity-type securities in their portfolios, including convertible securities. The fund may also invest in various actively managed funds. The fund is not designed to track an index or group of indexes. Equity-type securities include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. Certain equity underlying funds may invest in initial public offerings (IPOs). Each of the equity underlying funds has its own investment strategy that, for example, may focus on growth stocks or value stocks, or may employ a strategy combining growth and income stocks, and/or may invest in derivatives such as credit default swaps, foreign currency forwards, interest rate swaps, options on securities, and futures contracts. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from shorter to longer term. The fixed-income underlying funds collectively hold various types of debt instruments such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging market securities). Certain underlying funds may invest in illiquid securities, and certain underlying funds may be non-diversified.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest directly in exchange-traded funds (ETFs), exchange-traded notes (ETNs), the securities of other investment companies, U.S. government securities, and other types of investments such as derivatives, including credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, in each case for the purposes of reducing risk, obtaining efficient market exposure, and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;To the extent legally permitted, the Board of Trustees of the fund may, in its discretion, determine to combine the fund with another fund without shareholder approval if the target allocation of the fund matches the target allocation of the other fund, although there is no assurance that the Board of Trustees will so determine at any point.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund bears its own expenses and, in addition, indirectly bears its proportionate share of the expenses of the underlying funds in which it invests. The fund's performance reflects both the managers' allocation decisions and the performance of the underlying funds.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in equity securities than John Hancock Multi-Index Preservation Portfolios with closer target dates, equity security risks are more prevalent in this fund than in these other target-date funds. In addition to equity securities risk, the fund's other main risk factors are listed in alphabetical order.&lt;/div&gt;

               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk based on the nature of their support.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;

               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;

               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;

               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;

               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;

               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;

               &lt;b&gt;Lifecycle risk.&lt;/b&gt; Managers might not correctly predict market or economic conditions, and you could lose money even close to, during, or after the fund's designated retirement year.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Target allocation risk.&lt;/b&gt; The fund's risk profile will change due to reallocation or rebalancing of portfolio assets as the fund approaches its target date.&lt;/div&gt;

               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;

               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;

               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Short sales risk.&lt;/b&gt; Short sales involve costs and risk. A fund must pay the lender interest on the security it borrows, and the fund will lose money if the price of the security increases between the time of the short sale and the date when the fund replaces the borrowed security.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

The information shows how the fund's performance compares with the returns of an index of funds with similar investment objectives. From December 1, 2016 to November 30, 2017, the Custom Benchmark consisted of the following indices and approximate weightings: 54.60% Russell 3000 Index, 23.40% MSCI ACWI ex-USA Index, and 22.00% Bloomberg Barclays U.S. Aggregate Bond Index. The weightings of the indices in the Custom Benchmark are adjusted annually to reflect changes in the fund's target asset allocation in accordance with the annual roll-down of the glide path described above and differed in periods prior to December 1, 2016.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 12% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests substantially all of its assets in underlying funds using an asset allocation strategy designed for investors expected to retire around the year 2045.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The portfolio managers of the fund allocate assets among the underlying funds according to an asset allocation strategy that becomes increasingly conservative over time. John Hancock Multi-Index 2045 Lifetime Portfolio has a target asset allocation of 95% of its assets in underlying funds that invest primarily in equity securities. The fund will have a greater exposure to underlying funds that invest primarily in equity securities than will a John Hancock Multi-Index Lifetime Portfolio with a closer target date. To reduce investment risk and volatility as retirement approaches and in the postretirement years, the asset allocation strategy will change over time according to a predetermined "glide path" shown in the following chart. The fund may be a primary source of income for its shareholders after retirement.&lt;/div&gt;          
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                  GLIDE PATH CHART               
               &lt;/b&gt;&lt;/div&gt;   
 &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;/div&gt;          
                     &lt;img alt="glidepath chart" src="glidepath3.jpg"&gt;&lt;/img&gt;   
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The allocations reflected in the glide path are referred to as target allocations because they do not reflect active decisions made by the portfolio managers to produce an overweight or an underweight position in a particular asset class. The fund has a target allocation to underlying funds that invest in the broad asset classes of equity and fixed-income securities, but may also allocate its assets to underlying funds that invest outside these asset classes to protect the fund or help it achieve its objective. For example, the fund may also allocate its assets to underlying funds that invest in alternative and specialty asset classes. The managers may change the target allocation without shareholder approval if they believe that such change would benefit the fund and its shareholders. Under normal circumstances, any deviation from the target allocation is not expected to be greater than plus or minus 10%.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Within the prescribed percentage allocation, the managers select the percentage level to be maintained in specific underlying funds. New investments made by the fund may be directed to particular underlying funds in an effort to maintain the desired target allocations. There is no guarantee that the portfolio managers will correctly predict the market or economic conditions and, as with other mutual fund investments, you could lose money even if the fund is at or close to its designated retirement year or in its postretirement stage.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is designed for investors who may remain invested in the fund through their retirement years. The fund will continue to be managed according to an allocation strategy that becomes increasingly conservative over time until approximately twenty years after retirement, at which time the fund expects to maintain a static allocation of approximately 25% of its assets in equity underlying funds.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in underlying funds that invest in a broad range of equity, fixed-income, and alternative/specialty securities and asset classes, including, but not limited to, U.S. and foreign securities, including emerging-market securities, commodities, asset-backed securities, small-cap securities, and below-investment-grade securities (i.e., junk bonds). The underlying funds may also use derivatives, such as swaps, foreign currency forwards, futures, and options, in each case for the purposes of reducing risk, obtaining efficient market exposure and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund will invest in various passively managed underlying funds that as a group hold a wide range of equity-type securities in their portfolios, including convertible securities. The fund may also invest in various actively managed funds. The fund is not designed to track an index or group of indexes. Equity-type securities include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. Certain equity underlying funds may invest in initial public offerings (IPOs). Each of the equity underlying funds has its own investment strategy that, for example, may focus on growth stocks or value stocks, or may employ a strategy combining growth and income stocks, and/or may invest in derivatives such as credit default swaps, foreign currency forwards, interest rate swaps, options on securities, and futures contracts. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from shorter to longer term. The fixed-income underlying funds collectively hold various types of debt instruments such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging market securities). Certain underlying funds may invest in illiquid securities, and certain underlying funds may be non-diversified.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest directly in exchange-traded funds (ETFs), exchange-traded notes (ETNs), the securities of other investment companies, U.S. government securities, and other types of investments such as derivatives, including credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, in each case for the purposes of reducing risk, obtaining efficient market exposure, and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;To the extent permitted by law, the Board of Trustees of the fund may, in its discretion, determine to combine the fund with another fund without shareholder approval if the target allocation of the fund matches the target allocation of the other fund, although there is no assurance that the Board of Trustees will so determine at any point. The fund bears its own expenses and, in addition, indirectly bears its proportionate share of the expenses of the underlying funds in which it invests. The fund's performance reflects both the managers' allocation decisions and the performance of the underlying funds.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is subject to risks, and you could lose money by investing in the fund. The principal risks of investing in the fund are listed below.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in equity securities than John Hancock Multi-Index Lifetime Portfolios with closer target dates, equity security risks are more prevalent in this fund than in these other target-date funds. In addition to equity securities risk, the fund's other main risk factors are listed in alphabetical order.&lt;/div&gt;

                 &lt;i&gt; Principal risks of investing in the fund of funds  &lt;/i&gt;             
               &lt;/b&gt;&lt;/div&gt;             
                     
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk based on the nature of their support.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Investment company securities risk.&lt;/b&gt; A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lifecycle risk.&lt;/b&gt; Managers might not correctly predict market or economic conditions, and you could lose money even close to, during, or after the fund's designated retirement year.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Target allocation risk.&lt;/b&gt; The fund's risk profile will change due to reallocation or rebalancing of portfolio assets as the fund approaches its target date.&lt;/div&gt;         
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                &lt;i&gt;  Principal risks of investing in the underlying funds  &lt;/i&gt;             
               &lt;/b&gt;&lt;/div&gt;             
                     
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The following information illustrates the variability of the fund's returns and provides some indication of the risks of investing in the fund by showing changes in the fund's performance from year to year and by showing how the fund's average annual returns compared with a broad-based market index. Past performance (before and after taxes) does not indicate future results. All figures assume dividend reinvestment. Performance information is updated daily, monthly, and quarterly and may be obtained at our website, jhinvestments.com, or by calling 800-344-1029 between 8:00 A.M. and 7:00 P.M., Eastern time, on most business days.&lt;/div&gt;

The information shows how the fund's performance compares with the returns of an index of funds with similar investment objectives. From November 7, 2013 to November 30, 2017, the Custom Benchmark consisted of the following indices and approximate weightings: 66.50% Russell 3000 Index, 28.50% MSCI ACWI ex-USA Index, 4.00% Bloomberg Barclays U.S. Aggregate Bond Index, and 1.00% ICE Bank of America Merrill Lynch U.S. High Yield Master II Index. The weightings of the indices in the Custom Benchmark are adjusted annually to reflect changes in the fund's target asset allocation in accordance with the annual roll-down of the glide path described above.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 12% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund primarily invests its assets in underlying funds using an asset allocation strategy designed for investors expected to retire around the year 2045.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The portfolio managers of the fund allocate assets among the underlying funds according to an asset allocation strategy that becomes increasingly conservative over time. John Hancock Multi-Index 2045 Preservation Portfolio has a target asset allocation of 80.50% of its assets in underlying funds that invest primarily in equity securities. The fund will have a greater exposure to underlying funds that invest primarily in equity securities than will a John Hancock Multi-Index Preservation Portfolio with a closer target date. To attempt to reduce investment risk and volatility as retirement approaches, the asset allocation strategy will change over time according to a predetermined glide path shown in the following chart.&lt;/div&gt;         
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                  GLIDE PATH CHART               
               &lt;/b&gt;&lt;/div&gt;             
          &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;/div&gt;            
                  &lt;img alt="glidepath chart" src="glidepath2.jpg"&gt;&lt;/img&gt;  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The allocations reflected in the glide path are referred to as neutral because they do not reflect active decisions made by the portfolio managers to produce an overweight or an underweight position in a particular asset class. The fund has a target allocation to underlying funds that invest in the broad asset classes of equity and fixed-income securities but may also allocate its assets to underlying funds that invest outside these asset classes to protect the fund or help it achieve its objective. For example, the fund may also allocate its assets to underlying funds that invest in alternative and specialty asset classes. The investment advisor may change the target allocation without shareholder approval if it believes such change would benefit the fund and its shareholders. There is no guarantee that the managers will correctly predict the market or economic conditions. There is no guarantee that the fund will preserve either income or capital and, as with other mutual fund investments, you could lose money even if the fund is at or close to its designated retirement year. Under normal circumstances, any deviation from the target allocation is not expected to be greater than plus or minus 10%.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is designed for investors who anticipate reevaluating their retirement allocation strategies at the target date. Under normal market conditions, the fund expects to allocate 8% of its assets to equity underlying funds in its designated retirement year and to maintain that static allocation thereafter. This static allocation may be appropriate for some investors, but others may wish to reallocate their investments at retirement.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in underlying funds that invest in a broad range of equity, fixed-income, and alternative/specialty securities and asset classes, including, but not limited to, U.S. and foreign securities, including emerging-market securities, commodities, asset-backed securities, small-cap securities, and below-investment-grade securities (i.e., junk bonds). The underlying funds may also use derivatives, such as swaps, foreign currency forwards, futures, and options, in each case for the purposes of reducing risk, obtaining efficient market exposure and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund will invest in various passively managed underlying funds that as a group hold a wide range of equity-type securities in their portfolios, including convertible securities. The fund may also invest in various actively managed funds. The fund is not designed to track an index or group of indexes. Equity-type securities include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. Certain equity underlying funds may invest in initial public offerings (IPOs). Each of the equity underlying funds has its own investment strategy that, for example, may focus on growth stocks or value stocks, or may employ a strategy combining growth and income stocks, and/or may invest in derivatives such as credit default swaps, foreign currency forwards, interest rate swaps, options on securities, and futures contracts. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from shorter to longer term. The fixed-income underlying funds collectively hold various types of debt instruments such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging market securities). Certain underlying funds may invest in illiquid securities, and certain underlying funds may be non-diversified.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest directly in exchange-traded funds (ETFs), exchange-traded notes (ETNs), the securities of other investment companies, U.S. government securities, and other types of investments such as derivatives, including credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, in each case for the purposes of reducing risk, obtaining efficient market exposure, and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;To the extent legally permitted, the Board of Trustees of the fund may, in its discretion, determine to combine the fund with another fund without shareholder approval if the target allocation of the fund matches the target allocation of the other fund, although there is no assurance that the Board of Trustees will so determine at any point.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund bears its own expenses and, in addition, indirectly bears its proportionate share of the expenses of the underlying funds in which it invests. The fund's performance reflects both the managers' allocation decisions and the performance of the underlying funds.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is subject to risks, and you could lose money by investing in the fund.  The principal risks of investing in the fund are listed below.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in equity securities than John Hancock Multi-Index Preservation Portfolios with closer target dates, equity security risks are more prevalent in this fund than in these other target-date funds. In addition to equity securities risk, the fund's other main risk factors are listed in alphabetical order.&lt;/div&gt;

                  &lt;i&gt;Principal risks of investing in the fund of funds   &lt;/i&gt;            
               &lt;/b&gt;&lt;/div&gt;             
                     
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk based on the nature of their support.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Investment company securities risk.&lt;/b&gt; A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lifecycle risk.&lt;/b&gt; Managers might not correctly predict market or economic conditions, and you could lose money even close to, during, or after the fund's designated retirement year.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Target allocation risk.&lt;/b&gt; The fund's risk profile will change due to reallocation or rebalancing of portfolio assets as the fund approaches its target date.&lt;/div&gt;         
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
              &lt;i&gt;    Principal risks of investing in the underlying funds      &lt;/i&gt;         
               &lt;/b&gt;&lt;/div&gt;             
                     
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall.

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The following information illustrates the variability of the fund's returns and provides some indication of the risks of investing in the fund by showing changes in the fund's performance from year to year and by showing how the fund's average annual returns compared with a broad-based market index. Past performance (before and after taxes) does not indicate future results. All figures assume dividend reinvestment. Performance information is updated daily, monthly, and quarterly and may be obtained at our website, jhinvestments.com, or by calling 800-344-1029 between 8:00 A.M. and 7:00 P.M., Eastern time, on most business days.&lt;/div&gt;

The information shows how the fund's performance compares with the returns of an index of funds with similar investment objectives. From December 1, 2016 to November 30, 2017, the Custom Benchmark consisted of the following indices and approximate weightings: 57.05% Russell 3000 Index, 24.45% MSCI ACWI ex-USA Index, and 18.50% Bloomberg Barclays U.S. Aggregate Bond Index. The weightings of the indices in the Custom Benchmark are adjusted annually to reflect changes in the fund's target asset allocation in accordance with the annual roll-down of the glide path described above.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 14% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests substantially all of its assets in underlying funds using an asset allocation strategy designed for investors expected to retire around the year 2050.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The portfolio managers of the fund allocate assets among the underlying funds according to an asset allocation strategy that becomes increasingly conservative over time. John Hancock Multi-Index 2050 Lifetime Portfolio has a target asset allocation of 95% of its assets in underlying funds that invest primarily in equity securities. The fund will have a greater exposure to underlying funds that invest primarily in equity securities than will a John Hancock Multi-Index Lifetime Portfolio with a closer target date. To reduce investment risk and volatility as retirement approaches and in the postretirement years, the asset allocation strategy will change over time according to a predetermined "glide path" shown in the following chart. The fund may be a primary source of income for its shareholders after retirement.&lt;/div&gt;          
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                  GLIDE PATH CHART               
               &lt;/b&gt;&lt;/div&gt;             
              &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;/div&gt;        
                   &lt;img alt="glidepath chart" src="glidepath3.jpg"&gt;&lt;/img&gt;  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The allocations reflected in the glide path are referred to as target allocations because they do not reflect active decisions made by the portfolio managers to produce an overweight or an underweight position in a particular asset class. The fund has a target allocation to underlying funds that invest in the broad asset classes of equity and fixed-income securities, but may also allocate its assets to underlying funds that invest outside these asset classes to protect the fund or help it achieve its objective. For example, the fund may also allocate its assets to underlying funds that invest in alternative and specialty asset classes. The managers may change the target allocation without shareholder approval if they believe that such change would benefit the fund and its shareholders. Under normal circumstances, any deviation from the target allocation is not expected to be greater than plus or minus 10%.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Within the prescribed percentage allocation, the managers select the percentage level to be maintained in specific underlying funds. New investments made by the fund may be directed to particular underlying funds in an effort to maintain the desired target allocations. There is no guarantee that the portfolio managers will correctly predict the market or economic conditions and, as with other mutual fund investments, you could lose money even if the fund is at or close to its designated retirement year or in its postretirement stage.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is designed for investors who may remain invested in the fund through their retirement years. The fund will continue to be managed according to an allocation strategy that becomes increasingly conservative over time until approximately twenty years after retirement, at which time the fund expects to maintain a static allocation of approximately 25% of its assets in equity underlying funds.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in underlying funds that invest in a broad range of equity, fixed-income, and alternative/specialty securities and asset classes, including, but not limited to, U.S. and foreign securities, including emerging-market securities, commodities, asset-backed securities, small-cap securities, and below-investment-grade securities (i.e., junk bonds). The underlying funds may also use derivatives, such as swaps, foreign currency forwards, futures, and options, in each case for the purposes of reducing risk, obtaining efficient market exposure and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund will invest in various passively managed underlying funds that as a group hold a wide range of equity-type securities in their portfolios, including convertible securities. The fund may also invest in various actively managed funds. The fund is not designed to track an index or group of indexes. Equity-type securities include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. Certain equity underlying funds may invest in initial public offerings (IPOs). Each of the equity underlying funds has its own investment strategy that, for example, may focus on growth stocks or value stocks, or may employ a strategy combining growth and income stocks, and/or may invest in derivatives such as credit default swaps, foreign currency forwards, interest rate swaps, options on securities, and futures contracts. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from shorter to longer term. The fixed-income underlying funds collectively hold various types of debt instruments such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging market securities). Certain underlying funds may invest in illiquid securities, and certain underlying funds may be non-diversified.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest directly in exchange-traded funds (ETFs), exchange-traded notes (ETNs), the securities of other investment companies, U.S. government securities, and other types of investments such as derivatives, including credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, in each case for the purposes of reducing risk, obtaining efficient market exposure, and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;To the extent permitted by law, the Board of Trustees of the fund may, in its discretion, determine to combine the fund with another fund without shareholder approval if the target allocation of the fund matches the target allocation of the other fund, although there is no assurance that the Board of Trustees will so determine at any point. The fund bears its own expenses and, in addition, indirectly bears its proportionate share of the expenses of the underlying funds in which it invests. The fund's performance reflects both the managers' allocation decisions and the performance of the underlying funds.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is subject to risks, and you could lose money by investing in the fund. The principal risks of investing in the fund are listed below.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in equity securities than John Hancock Multi-Index Lifetime Portfolios with closer target dates, equity security risks are more prevalent in this fund than in these other target-date funds. In addition to equity securities risk, the fund's other main risk factors are listed in alphabetical order.&lt;/div&gt;          
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                 &lt;i&gt; Principal risks of investing in the fund of funds &lt;/i&gt;              
               &lt;/b&gt;&lt;/div&gt;             
                     
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk based on the nature of their support.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Investment company securities risk.&lt;/b&gt; A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lifecycle risk.&lt;/b&gt; Managers might not correctly predict market or economic conditions, and you could lose money even close to, during, or after the fund's designated retirement year.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Target allocation risk.&lt;/b&gt; The fund's risk profile will change due to reallocation or rebalancing of portfolio assets as the fund approaches its target date.&lt;/div&gt;         
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                &lt;i&gt;  Principal risks of investing in the underlying funds   &lt;/i&gt;            
               &lt;/b&gt;&lt;/div&gt;             
                     
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;

               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;

               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;

               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;

               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;

               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;

               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;

               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;

               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

Past performance (before and after taxes) does not indicate future results. All figures assume dividend reinvestment. Performance information is updated daily, monthly, and quarterly and may be obtained at our website, jhinvestments.com, or by calling 800-344-1029 between 8:00 A.M. and 7:00 P.M., Eastern time, on most business days.&lt;/div&gt;

The information shows how the fund's performance compares with the returns of an index of funds with similar investment objectives. From November 7, 2013 to November 30, 2017, the Custom Benchmark consisted of the following indices and approximate weightings: 66.50% Russell 3000 Index, 28.50% MSCI ACWI ex-USA Index, 4.00% Bloomberg Barclays U.S. Aggregate Bond Index, and 1.00% ICE Bank of America Merrill Lynch U.S. High Yield Master II Index. The weightings of the indices in the Custom Benchmark are adjusted annually to reflect changes in the fund's target asset allocation in accordance with the annual roll-down of the glide path described above.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;This example is intended to help you compare the cost of investing in the fund with the cost of investing in other mutual funds. Please see below a hypothetical example showing the expenses of a $10,000 investment for the time periods indicated and then assuming you sell all of your shares at the end of those periods. The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 13% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund primarily invests its assets in underlying funds using an asset allocation strategy designed for investors expected to retire around the year 2050.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The portfolio managers of the fund allocate assets among the underlying funds according to an asset allocation strategy that becomes increasingly conservative over time. John Hancock Multi-Index 2050 Preservation Portfolio has a target asset allocation of 82% of its assets in underlying funds that invest primarily in equity securities. The fund will have a greater exposure to underlying funds that invest primarily in equity securities than will a John Hancock Multi-Index Preservation Portfolio with a closer target date. To attempt to reduce investment risk and volatility as retirement approaches, the asset allocation strategy will change over time according to a predetermined glide path shown in the following chart.&lt;/div&gt;          
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                  GLIDE PATH CHART               
               &lt;/b&gt;&lt;/div&gt;             
           &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;/div&gt;           
                  &lt;img alt="glidepath chart" src="glidepath2.jpg"&gt;&lt;/img&gt;  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The allocations reflected in the glide path are referred to as neutral because they do not reflect active decisions made by the portfolio managers to produce an overweight or an underweight position in a particular asset class. The fund has a target allocation to underlying funds that invest in the broad asset classes of equity and fixed-income securities but may also allocate its assets to underlying funds that invest outside these asset classes to protect the fund or help it achieve its objective. For example, the fund may also allocate its assets to underlying funds that invest in alternative and specialty asset classes. The investment advisor may change the target allocation without shareholder approval if it believes such change would benefit the fund and its shareholders. There is no guarantee that the managers will correctly predict the market or economic conditions. There is no guarantee that the fund will preserve either income or capital and, as with other mutual fund investments, you could lose money even if the fund is at or close to its designated retirement year. Under normal circumstances, any deviation from the target allocation is not expected to be greater than plus or minus 10%.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is designed for investors who anticipate reevaluating their retirement allocation strategies at the target date. Under normal market conditions, the fund expects to allocate 8% of its assets to equity underlying funds in its designated retirement year and to maintain that static allocation thereafter. This static allocation may be appropriate for some investors, but others may wish to reallocate their investments at retirement.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in underlying funds that invest in a broad range of equity, fixed-income, and alternative/specialty securities and asset classes, including, but not limited to, U.S. and foreign securities, including emerging-market securities, commodities, asset-backed securities, small-cap securities, and below-investment-grade securities (i.e., junk bonds). The underlying funds may also use derivatives, such as swaps, foreign currency forwards, futures, and options, in each case for the purposes of reducing risk, obtaining efficient market exposure and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund will invest in various passively managed underlying funds that as a group hold a wide range of equity-type securities in their portfolios, including convertible securities. The fund may also invest in various actively managed funds. The fund is not designed to track an index or group of indexes. Equity-type securities include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. Certain equity underlying funds may invest in initial public offerings (IPOs). Each of the equity underlying funds has its own investment strategy that, for example, may focus on growth stocks or value stocks, or may employ a strategy combining growth and income stocks, and/or may invest in derivatives such as credit default swaps, foreign currency forwards, interest rate swaps, options on securities, and futures contracts. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from shorter to longer term. The fixed-income underlying funds collectively hold various types of debt instruments such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging market securities). Certain underlying funds may invest in illiquid securities, and certain underlying funds may be non-diversified.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest directly in exchange-traded funds (ETFs), exchange-traded notes (ETNs), the securities of other investment companies, U.S. government securities, and other types of investments such as derivatives, including credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, in each case for the purposes of reducing risk, obtaining efficient market exposure, and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;To the extent legally permitted, the Board of Trustees of the fund may, in its discretion, determine to combine the fund with another fund without shareholder approval if the target allocation of the fund matches the target allocation of the other fund, although there is no assurance that the Board of Trustees will so determine at any point.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund bears its own expenses and, in addition, indirectly bears its proportionate share of the expenses of the underlying funds in which it invests. The fund's performance reflects both the managers' allocation decisions and the performance of the underlying funds.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is subject to risks, and you could lose money by investing in the fund.  The principal risks of investing in the fund are listed below.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in equity securities than John Hancock Multi-Index Preservation Portfolios with closer target dates, equity security risks are more prevalent in this fund than in these other target-date funds. In addition to equity securities risk, the fund's other main risk factors are listed in alphabetical order.&lt;/div&gt;         
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                 &lt;i&gt; Principal risks of investing in the fund of funds &lt;/i&gt;              
               &lt;/b&gt;&lt;/div&gt;             
                     
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk based on the nature of their support.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Investment company securities risk.&lt;/b&gt; A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lifecycle risk.&lt;/b&gt; Managers might not correctly predict market or economic conditions, and you could lose money even close to, during, or after the fund's designated retirement year.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Target allocation risk.&lt;/b&gt; The fund's risk profile will change due to reallocation or rebalancing of portfolio assets as the fund approaches its target date.&lt;/div&gt;         
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                &lt;i&gt;  Principal risks of investing in the underlying funds     &lt;/i&gt;          
               &lt;/b&gt;&lt;/div&gt;             
                     
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Short sales risk.&lt;/b&gt; Short sales involve costs and risk. A fund must pay the lender interest on the security it borrows, and the fund will lose money if the price of the security increases between the time of the short sale and the date when the fund replaces the borrowed security.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The following information illustrates the variability of the fund's returns and provides some indication of the risks of investing in the fund by showing changes in the fund's performance from year to year and by showing how the fund's average annual returns compared with a broad-based market index. Past performance (before and after taxes) does not indicate future results. All figures assume dividend reinvestment. Performance information is updated daily, monthly, and quarterly and may be obtained at our website, jhinvestments.com, or by calling 800-344-1029 between 8:00 A.M. and 7:00 P.M., Eastern time, on most business days.&lt;/div&gt;

The information shows how the fund's performance compares with the returns of an index of funds with similar investment objectives. From April 29, 2011 to November 30, 2017, the Custom Benchmark consisted of the following indices and approximate weightings: 57.40% Russell 3000 Index, 24.60% MSCI ACWI ex-USA Index, and 18.00% Bloomberg Barclays U.S. Aggregate Bond Index. The weightings of the indices in the Custom Benchmark are adjusted annually to reflect changes in the fund's target asset allocation in accordance with the annual roll-down of the glide path described above.&lt;/div&gt;

The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 17% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests substantially all of its assets in underlying funds using an asset allocation strategy designed for investors expected to retire around the year 2055.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The portfolio managers of the fund allocate assets among the underlying funds according to an asset allocation strategy that becomes increasingly conservative over time. John Hancock Multi-Index 2055 Lifetime Portfolio has a target asset allocation of 95% of its assets in underlying funds that invest primarily in equity securities. The fund will have a greater exposure to underlying funds that invest primarily in equity securities than will a John Hancock Multi-Index Lifetime Portfolio with a closer target date. To reduce investment risk and volatility as retirement approaches and in the postretirement years, the asset allocation strategy will change over time according to a predetermined "glide path" shown in the following chart. The fund may be a primary source of income for its shareholders after retirement.&lt;/div&gt;          
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                  GLIDE PATH CHART               
               &lt;/b&gt;&lt;/div&gt;             
                 &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;/div&gt;     
                   &lt;img alt="glidepath chart" src="glidepath3.jpg"&gt;&lt;/img&gt;  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The allocations reflected in the glide path are referred to as target allocations because they do not reflect active decisions made by the portfolio managers to produce an overweight or an underweight position in a particular asset class. The fund has a target allocation to underlying funds that invest in the broad asset classes of equity and fixed-income securities, but may also allocate its assets to underlying funds that invest outside these asset classes to protect the fund or help it achieve its objective. For example, the fund may also allocate its assets to underlying funds that invest in alternative and specialty asset classes. The managers may change the target allocation without shareholder approval if they believe that such change would benefit the fund and its shareholders. Under normal circumstances, any deviation from the target allocation is not expected to be greater than plus or minus 10%.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Within the prescribed percentage allocation, the managers select the percentage level to be maintained in specific underlying funds. New investments made by the fund may be directed to particular underlying funds in an effort to maintain the desired target allocations. There is no guarantee that the portfolio managers will correctly predict the market or economic conditions and, as with other mutual fund investments, you could lose money even if the fund is at or close to its designated retirement year or in its postretirement stage.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is designed for investors who may remain invested in the fund through their retirement years. The fund will continue to be managed according to an allocation strategy that becomes increasingly conservative over time until approximately twenty years after retirement, at which time the fund expects to maintain a static allocation of approximately 25% of its assets in equity underlying funds.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in underlying funds that invest in a broad range of equity, fixed-income, and alternative/specialty securities and asset classes, including, but not limited to, U.S. and foreign securities, including emerging-market securities, commodities, asset-backed securities, small-cap securities, and below-investment-grade securities (i.e., junk bonds). The underlying funds may also use derivatives, such as swaps, foreign currency forwards, futures, and options, in each case for the purposes of reducing risk, obtaining efficient market exposure and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund will invest in various passively managed underlying funds that as a group hold a wide range of equity-type securities in their portfolios, including convertible securities. The fund may also invest in various actively managed funds. The fund is not designed to track an index or group of indexes. Equity-type securities include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. Certain equity underlying funds may invest in initial public offerings (IPOs). Each of the equity underlying funds has its own investment strategy that, for example, may focus on growth stocks or value stocks, or may employ a strategy combining growth and income stocks, and/or may invest in derivatives such as credit default swaps, foreign currency forwards, interest rate swaps, options on securities, and futures contracts. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from shorter to longer term. The fixed-income underlying funds collectively hold various types of debt instruments such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging market securities). Certain underlying funds may invest in illiquid securities, and certain underlying funds may be non-diversified.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest directly in exchange-traded funds (ETFs), exchange-traded notes (ETNs), the securities of other investment companies, U.S. government securities, and other types of investments such as derivatives, including credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, in each case for the purposes of reducing risk, obtaining efficient market exposure, and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;To the extent permitted by law, the Board of Trustees of the fund may, in its discretion, determine to combine the fund with another fund without shareholder approval if the target allocation of the fund matches the target allocation of the other fund, although there is no assurance that the Board of Trustees will so determine at any point. The fund bears its own expenses and, in addition, indirectly bears its proportionate share of the expenses of the underlying funds in which it invests. The fund's performance reflects both the managers' allocation decisions and the performance of the underlying funds.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in equity securities than John Hancock Multi-Index Lifetime Portfolios with closer target dates, equity security risks are more prevalent in this fund than in these other target-date funds. In addition to equity securities risk, the fund's other main risk factors are listed in alphabetical order.&lt;/div&gt;          
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;

               &lt;/b&gt;&lt;/div&gt;             
                     
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk based on the nature of their support.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;

               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;

               &lt;b&gt;Target allocation risk.&lt;/b&gt; The fund's risk profile will change due to reallocation or rebalancing of portfolio assets as the fund approaches its target date.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;

               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

The information shows how the fund's performance compares with the returns of an index of funds with similar investment objectives. From March 26, 2014 to November 30, 2017, the Custom Benchmark consisted of the following indices and approximate weightings: 66.50% Russell 3000 Index, 28.50% MSCI ACWI ex-USA Index, 4.00% Bloomberg Barclays U.S. Aggregate Bond Index, and 1.00% ICE Bank of America Merrill Lynch U.S. High Yield Master II Index. The weightings of the indices in the Custom Benchmark are adjusted annually to reflect changes in the fund's target asset allocation in accordance with the annual rolldown of the glide path described above.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 10% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund primarily invests its assets in underlying funds using an asset allocation strategy designed for investors expected to retire around the year 2055.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The portfolio managers of the fund allocate assets among the underlying funds according to an asset allocation strategy that becomes increasingly conservative over time. John Hancock Multi-Index 2055 Preservation Portfolio has a target asset allocation of 82% of its assets in underlying funds that invest primarily in equity securities. The fund will have a greater exposure to underlying funds that invest primarily in equity securities than will a John Hancock Multi-Index Preservation Portfolio with a closer target date. To attempt to reduce investment risk and volatility as retirement approaches, the asset allocation strategy will change over time according to a predetermined glide path shown in the following chart.&lt;/div&gt;          
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                  GLIDE PATH CHART               
               &lt;/b&gt;&lt;/div&gt;  
 &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;/div&gt;           
                    &lt;img alt="glidepath chart" src="glidepath2.jpg"&gt;&lt;/img&gt;   
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The allocations reflected in the glide path are referred to as neutral because they do not reflect active decisions made by the portfolio managers to produce an overweight or an underweight position in a particular asset class. The fund has a target allocation to underlying funds that invest in the broad asset classes of equity and fixed-income securities but may also allocate its assets to underlying funds that invest outside these asset classes to protect the fund or help it achieve its objective. For example, the fund may also allocate its assets to underlying funds that invest in alternative and specialty asset classes. The investment advisor may change the target allocation without shareholder approval if it believes such change would benefit the fund and its shareholders. There is no guarantee that the managers will correctly predict the market or economic conditions. There is no guarantee that the fund will preserve either income or capital and, as with other mutual fund investments, you could lose money even if the fund is at or close to its designated retirement year. Under normal circumstances, any deviation from the target allocation is not expected to be greater than plus or minus 10%.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is designed for investors who anticipate reevaluating their retirement allocation strategies at the target date. Under normal market conditions, the fund expects to allocate 8% of its assets to equity underlying funds in its designated retirement year and to maintain that static allocation thereafter. This static allocation may be appropriate for some investors, but others may wish to reallocate their investments at retirement.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in underlying funds that invest in a broad range of equity, fixed-income, and alternative/specialty securities and asset classes, including, but not limited to, U.S. and foreign securities, including emerging-market securities, commodities, asset-backed securities, small-cap securities, and below-investment-grade securities (i.e., junk bonds). The underlying funds may also use derivatives, such as swaps, foreign currency forwards, futures, and options, in each case for the purposes of reducing risk, obtaining efficient market exposure and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund will invest in various passively managed underlying funds that as a group hold a wide range of equity-type securities in their portfolios, including convertible securities. The fund may also invest in various actively managed funds. The fund is not designed to track an index or group of indexes. Equity-type securities include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. Certain equity underlying funds may invest in initial public offerings (IPOs). Each of the equity underlying funds has its own investment strategy that, for example, may focus on growth stocks or value stocks, or may employ a strategy combining growth and income stocks, and/or may invest in derivatives such as credit default swaps, foreign currency forwards, interest rate swaps, options on securities, and futures contracts. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from shorter to longer term. The fixed-income underlying funds collectively hold various types of debt instruments such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging market securities). Certain underlying funds may invest in illiquid securities, and certain underlying funds may be non-diversified.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest directly in exchange-traded funds (ETFs), exchange-traded notes (ETNs), the securities of other investment companies, U.S. government securities, and other types of investments such as derivatives, including credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, in each case for the purposes of reducing risk, obtaining efficient market exposure, and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;To the extent legally permitted, the Board of Trustees of the fund may, in its discretion, determine to combine the fund with another fund without shareholder approval if the target allocation of the fund matches the target allocation of the other fund, although there is no assurance that the Board of Trustees will so determine at any point.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund bears its own expenses and, in addition, indirectly bears its proportionate share of the expenses of the underlying funds in which it invests. The fund's performance reflects both the managers' allocation decisions and the performance of the underlying funds.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in equity securities than John Hancock Multi-Index Preservation Portfolios with closer target dates, equity security risks are more prevalent in this fund than in these other target-date funds. In addition to equity securities risk, the fund's other main risk factors are listed in alphabetical order.&lt;/div&gt;

                 &lt;i&gt; Principal risks of investing in the fund of funds  &lt;/i&gt;             
               &lt;/b&gt;&lt;/div&gt;             
                     
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk based on the nature of their support.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;

               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;

               &lt;b&gt;Target allocation risk.&lt;/b&gt; The fund's risk profile will change due to reallocation or rebalancing of portfolio assets as the fund approaches its target date.&lt;/div&gt;         
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
               &lt;i&gt;   Principal risks of investing in the underlying funds   &lt;/i&gt;            
               &lt;/b&gt;&lt;/div&gt;             
                     
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Short sales risk.&lt;/b&gt; Short sales involve costs and risk. A fund must pay the lender interest on the security it borrows, and the fund will lose money if the price of the security increases between the time of the short sale and the date when the fund replaces the borrowed security.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The following information illustrates the variability of the fund's returns and provides some indication of the risks of investing in the fund by showing changes in the fund's performance from year to year and by showing how the fund's average annual returns compared with a broad-based market index. Past performance (before and after taxes) does not indicate future results. All figures assume dividend reinvestment. Performance information is updated daily, monthly, and quarterly and may be obtained at our website, jhinvestments.com, or by calling 800-344-1029 between 8:00 A.M. and 7:00 P.M., Eastern time, on most business days.&lt;/div&gt;

The information shows how the fund's performance compares with the returns of an index of funds with similar investment objectives. From March 26, 2014 to November 30, 2017, the Custom Benchmark consisted of the following indices and approximate weightings: 57.40% Russell 3000 Index, 24.60% MSCI ACWI ex-USA Index, and 18.00% Bloomberg Barclays U.S. Aggregate Bond Index. The weightings of the indices in the Custom Benchmark are adjusted annually to reflect changes in the fund's target asset allocation in accordance with the annual roll-down of the glide path described above.&lt;/div&gt;

The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 24% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests substantially all of its assets in underlying funds using an asset allocation strategy designed for investors expected to retire around the year 2060.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The portfolio managers of the fund allocate assets among the underlying funds according to an asset allocation strategy that becomes increasingly conservative over time. John Hancock Multi-Index 2060 Lifetime Portfolio has a target asset allocation of 95% of its assets in underlying funds that invest primarily in equity securities. The fund will have a greater exposure to underlying funds that invest primarily in equity securities than will a John Hancock Multi-Index Lifetime Portfolio with a closer target date. To reduce investment risk and volatility as retirement approaches and in the postretirement years, the asset allocation strategy will change over time according to a predetermined "glide path" shown in the following chart. The fund may be a primary source of income for its shareholders after retirement.&lt;/div&gt;          
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                  GLIDE PATH CHART               
               &lt;/b&gt;&lt;/div&gt;             
                      &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;/div&gt;
                  &lt;img alt="glidepath chart" src="glidepath3.jpg"&gt;&lt;/img&gt;  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The allocations reflected in the glide path are referred to as target allocations because they do not reflect active decisions made by the portfolio managers to produce an overweight or an underweight position in a particular asset class. The fund has a target allocation to underlying funds that invest in the broad asset classes of equity and fixed-income securities, but may also allocate its assets to underlying funds that invest outside these asset classes to protect the fund or help it achieve its objective. For example, the fund may also allocate its assets to underlying funds that invest in alternative and specialty asset classes. The managers may change the target allocation without shareholder approval if they believe that such change would benefit the fund and its shareholders. Under normal circumstances, any deviation from the target allocation is not expected to be greater than plus or minus 10%.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Within the prescribed percentage allocation, the managers select the percentage level to be maintained in specific underlying funds. New investments made by the fund may be directed to particular underlying funds in an effort to maintain the desired target allocations. There is no guarantee that the portfolio managers will correctly predict the market or economic conditions and, as with other mutual fund investments, you could lose money even if the fund is at or close to its designated retirement year or in its postretirement stage.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is designed for investors who may remain invested in the fund through their retirement years. The fund will continue to be managed according to an allocation strategy that becomes increasingly conservative over time until approximately twenty years after retirement, at which time the fund expects to maintain a static allocation of approximately 25% of its assets in equity underlying funds.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in underlying funds that invest in a broad range of equity, fixed-income, and alternative/specialty securities and asset classes, including, but not limited to, U.S. and foreign securities, including emerging-market securities, commodities, asset-backed securities, small-cap securities, and below-investment-grade securities (i.e., junk bonds). The underlying funds may also use derivatives, such as swaps, foreign currency forwards, futures, and options, in each case for the purposes of reducing risk, obtaining efficient market exposure and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund will invest in various passively managed underlying funds that as a group hold a wide range of equity-type securities in their portfolios, including convertible securities. The fund may also invest in various actively managed funds. The fund is not designed to track an index or group of indexes. Equity-type securities include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. Certain equity underlying funds may invest in initial public offerings (IPOs). Each of the equity underlying funds has its own investment strategy that, for example, may focus on growth stocks or value stocks, or may employ a strategy combining growth and income stocks, and/or may invest in derivatives such as credit default swaps, foreign currency forwards, interest rate swaps, options on securities, and futures contracts. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from shorter to longer term. The fixed-income underlying funds collectively hold various types of debt instruments such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging market securities). Certain underlying funds may invest in illiquid securities, and certain underlying funds may be non-diversified.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest directly in exchange-traded funds (ETFs), exchange-traded notes (ETNs), the securities of other investment companies, U.S. government securities, and other types of investments such as derivatives, including credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, in each case for the purposes of reducing risk, obtaining efficient market exposure, and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;To the extent permitted by law, the Board of Trustees of the fund may, in its discretion, determine to combine the fund with another fund without shareholder approval if the target allocation of the fund matches the target allocation of the other fund, although there is no assurance that the Board of Trustees will so determine at any point. The fund bears its own expenses and, in addition, indirectly bears its proportionate share of the expenses of the underlying funds in which it invests. The fund's performance reflects both the managers' allocation decisions and the performance of the underlying funds.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in equity securities than John Hancock Multi-Index Lifetime Portfolios with closer target dates, equity security risks are more prevalent in this fund than in these other target-date funds. In addition to equity securities risk, the fund's other main risk factors are listed in alphabetical order.&lt;/div&gt;

               &lt;/b&gt;&lt;/div&gt;             
                     
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk based on the nature of their support.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;

               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Investment company securities risk.&lt;/b&gt; A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;

               &lt;b&gt;Lifecycle risk.&lt;/b&gt; Managers might not correctly predict market or economic conditions, and you could lose money even close to, during, or after the fund's designated retirement year.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Target allocation risk.&lt;/b&gt; The fund's risk profile will change due to reallocation or rebalancing of portfolio assets as the fund approaches its target date.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

The information shows how the fund's performance compares with the returns of an index of funds with similar investment objectives. From March 30, 2016 to November 30, 2017, the Custom Benchmark consisted of the following indices and approximate weightings: 66.50% Russell 3000 Index, 28.50% MSCI ACWI ex-USA Index, 4.00% Bloomberg Barclays U.S. Aggregate Bond Index, and 1.00% ICE Bank of America Merrill Lynch U.S. High Yield Master II Index. The weightings of the indices in the Custom Benchmark are adjusted annually to reflect changes in the fund's target asset allocation in accordance with the annual rolldown of the glide path described above.&lt;/div&gt;

The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 10% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund primarily invests its assets in underlying funds using an asset allocation strategy designed for investors expected to retire around the year 2060.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The portfolio managers of the fund allocate assets among the underlying funds according to an asset allocation strategy that becomes increasingly conservative over time. John Hancock Multi-Index 2060 Preservation Portfolio has a target asset allocation of 82% of its assets in underlying funds that invest primarily in equity securities. The fund will have a greater exposure to underlying funds that invest primarily in equity securities than will a John Hancock Multi-Index Preservation Portfolio with a closer target date. To attempt to reduce investment risk and volatility as retirement approaches, the asset allocation strategy will change over time according to a predetermined glide path shown in the following chart.&lt;/div&gt;          
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                  GLIDE PATH CHART               
               &lt;/b&gt;&lt;/div&gt;           
 &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;/div&gt;  
                     &lt;img alt="glidepath chart" src="glidepath2.jpg"&gt;&lt;/img&gt;  
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The allocations reflected in the glide path are referred to as neutral because they do not reflect active decisions made by the portfolio managers to produce an overweight or an underweight position in a particular asset class. The fund has a target allocation to underlying funds that invest in the broad asset classes of equity and fixed-income securities but may also allocate its assets to underlying funds that invest outside these asset classes to protect the fund or help it achieve its objective. For example, the fund may also allocate its assets to underlying funds that invest in alternative and specialty asset classes. The investment advisor may change the target allocation without shareholder approval if it believes such change would benefit the fund and its shareholders. There is no guarantee that the managers will correctly predict the market or economic conditions. There is no guarantee that the fund will preserve either income or capital and, as with other mutual fund investments, you could lose money even if the fund is at or close to its designated retirement year. Under normal circumstances, any deviation from the target allocation is not expected to be greater than plus or minus 10%.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is designed for investors who anticipate reevaluating their retirement allocation strategies at the target date. Under normal market conditions, the fund expects to allocate 8% of its assets to equity underlying funds in its designated retirement year and to maintain that static allocation thereafter. This static allocation may be appropriate for some investors, but others may wish to reallocate their investments at retirement.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in underlying funds that invest in a broad range of equity, fixed-income, and alternative/specialty securities and asset classes, including, but not limited to, U.S. and foreign securities, including emerging-market securities, commodities, asset-backed securities, small-cap securities, and below-investment-grade securities (i.e., junk bonds). The underlying funds may also use derivatives, such as swaps, foreign currency forwards, futures, and options, in each case for the purposes of reducing risk, obtaining efficient market exposure and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund will invest in various passively managed underlying funds that as a group hold a wide range of equity-type securities in their portfolios, including convertible securities. The fund may also invest in various actively managed funds. The fund is not designed to track an index or group of indexes. Equity-type securities include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. Certain equity underlying funds may invest in initial public offerings (IPOs). Each of the equity underlying funds has its own investment strategy that, for example, may focus on growth stocks or value stocks, or may employ a strategy combining growth and income stocks, and/or may invest in derivatives such as credit default swaps, foreign currency forwards, interest rate swaps, options on securities, and futures contracts. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from shorter to longer term. The fixed-income underlying funds collectively hold various types of debt instruments such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging market securities). Certain underlying funds may invest in illiquid securities, and certain underlying funds may be non-diversified.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest directly in exchange-traded funds (ETFs), exchange-traded notes (ETNs), the securities of other investment companies, U.S. government securities, and other types of investments such as derivatives, including credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, in each case for the purposes of reducing risk, obtaining efficient market exposure, and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;To the extent legally permitted, the Board of Trustees of the fund may, in its discretion, determine to combine the fund with another fund without shareholder approval if the target allocation of the fund matches the target allocation of the other fund, although there is no assurance that the Board of Trustees will so determine at any point.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund bears its own expenses and, in addition, indirectly bears its proportionate share of the expenses of the underlying funds in which it invests. The fund's performance reflects both the managers' allocation decisions and the performance of the underlying funds.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in equity securities than John Hancock Multi-Index Preservation Portfolios with closer target dates, equity security risks are more prevalent in this fund than in these other target-date funds. In addition to equity securities risk, the fund's other main risk factors are listed in alphabetical order.&lt;/div&gt;

               &lt;/b&gt;&lt;/div&gt;             
                     
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk based on the nature of their support.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;

               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;

               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;

               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Investment company securities risk.&lt;/b&gt; A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lifecycle risk.&lt;/b&gt; Managers might not correctly predict market or economic conditions, and you could lose money even close to, during, or after the fund's designated retirement year.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Target allocation risk.&lt;/b&gt; The fund's risk profile will change due to reallocation or rebalancing of portfolio assets as the fund approaches its target date.&lt;/div&gt;         
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                 &lt;i&gt; Principal risks of investing in the underlying funds    &lt;/i&gt;           
               &lt;/b&gt;&lt;/div&gt;             
                     
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Short sales risk.&lt;/b&gt; Short sales involve costs and risk. A fund must pay the lender interest on the security it borrows, and the fund will lose money if the price of the security increases between the time of the short sale and the date when the fund replaces the borrowed security.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

The information shows how the fund's performance compares with the returns of an index of funds with similar investment objectives. From March 30, 2016 to November 30, 2017, the Custom Benchmark consisted of the following indices and approximate weightings: 57.40% Russell 3000 Index, 24.60% MSCI ACWI ex-USA Index, and 18.00% Bloomberg Barclays U.S. Aggregate Bond Index. The weightings of the indices in the Custom Benchmark are adjusted annually to reflect changes in the fund's target asset allocation in accordance with the annual roll-down of the glide path described above.&lt;/div&gt;

The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 7% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund primarily invests its assets in underlying funds using an asset allocation strategy designed for investors in or near retirement. Under normal market conditions, the fund is expected to maintain an allocation of about 8% of its assets in underlying funds that invest primarily in equity securities.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund typically will have greater exposure to underlying funds that invest primarily in fixed-income securities than will other John Hancock Multi-Index Preservation Portfolios, which are designed for investors who plan to retire around a specific target date.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund's allocations to equity and fixed-income are referred to as neutral because they do not reflect active decisions made by the portfolio managers to produce an overweight or an underweight position in a particular asset class. The fund has a target allocation to underlying funds that invest in the broad asset classes of equity and fixed-income securities but may also allocate its assets to underlying funds that invest outside these asset classes to protect the fund or help it achieve its objective. For example, the fund may also allocate its assets to underlying funds that invest in alternative and specialty asset classes. The investment advisor may change the target allocation without shareholder approval if it believes such change would benefit the fund and its shareholders. There is no guarantee that the managers will correctly predict the market or economic conditions. There is no guarantee that the fund will preserve either income or capital and, as with other mutual fund investments, you could lose money. Unlike other John Hancock Multi-Index Preservation Portfolios, the fund is not designed to decrease its equity holdings over time. The fund is designed for an investor in or near retirement, and it is anticipated that investors will make gradual withdrawals from the fund.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in underlying funds that invest in a broad range of equity, fixed-income, and alternative/specialty securities and asset classes, including, but not limited to, U.S. and foreign securities, including emerging-market securities, commodities, asset-backed securities, small-cap securities, and below-investment-grade securities (i.e., junk bonds). The underlying funds may also use derivatives, such as swaps, foreign currency forwards, futures, and options, in each case for the purposes of reducing risk, obtaining efficient market exposure and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund will invest in various passively managed underlying funds that as a group hold a wide range of equity-type securities in their portfolios, including convertible securities. The fund may also invest in various actively managed funds. The fund is not designed to track an index or group of indexes. Equity-type securities include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. Certain equity underlying funds may invest in initial public offerings (IPOs). Each of the equity underlying funds has its own investment strategy that, for example, may focus on growth stocks or value stocks, or may employ a strategy combining growth and income stocks, and/or may invest in derivatives such as credit default swaps, foreign currency forwards, interest rate swaps, options on securities, and futures contracts. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from shorter to longer term. The fixed-income underlying funds collectively hold various types of debt instruments such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging market securities). Certain underlying funds may invest in illiquid securities, and certain underlying funds may be non-diversified.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest directly in exchange-traded funds (ETFs), exchange-traded notes (ETNs), the securities of other investment companies, U.S. government securities, and other types of investments such as derivatives, including credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, in each case for the purposes of reducing risk, obtaining efficient market exposure, and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;To the extent legally permitted, the Board of Trustees of the fund may, in its discretion, determine to combine the fund with another fund without shareholder approval if the target allocation of the fund matches the target allocation of the other fund, although there is no assurance that the Board of Trustees will so determine at any point.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund bears its own expenses and, in addition, indirectly bears its proportionate share of the expenses of the underlying funds in which it invests. The fund's performance reflects both the managers' allocation decisions and the performance of the underlying funds.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in fixed-income securities than John Hancock Multi-Index Preservation Portfolios with target dates that are more distant, fixed-income securities risks are more prevalent in this fund than in these other target date funds. In addition to fixed-income securities risk, the fund's other main risk factors are listed in alphabetical order.&lt;/div&gt;          
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
               &lt;i&gt;   Principal risks of investing in the fund of funds   &lt;/i&gt;            
               &lt;/b&gt;&lt;/div&gt;             
                     
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk based on the nature of their support.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;

               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;

               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;

               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Investment company securities risk.&lt;/b&gt; A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lifecycle risk.&lt;/b&gt; Managers might not correctly predict market or economic conditions, and you could lose money even though the fund's designated retirement year has already passed.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Target allocation risk.&lt;/b&gt; The fund's risk profile will change due to reallocation or rebalancing of portfolio assets as the fund approaches its target date.&lt;/div&gt;

                &lt;i&gt;  Principal risks of investing in the underlying funds  &lt;/i&gt;             
               &lt;/b&gt;&lt;/div&gt;

               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions).

In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Short sales risk.&lt;/b&gt; Short sales involve costs and risk. A fund must pay the lender interest on the security it borrows, and the fund will lose money if the price of the security increases between the time of the short sale and the date when the fund replaces the borrowed security.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

The information shows how the fund's performance compares with the returns of an index of funds with similar investment objectives. From December 1, 2014, the Custom Benchmark has consisted of the following indices and approximate weightings: 5.60% Russell 3000 Index, 2.40% MSCI ACWI ex-USA Index, and 92.00% Bloomberg Barclays U.S. Aggregate Bond Index. Prior to reaching its current allocation, the weightings of the indices in the Custom Benchmark were adjusted annually to reflect changes in the fund's target asset allocation.&lt;/div&gt;

The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 20% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests substantially all of its assets in underlying funds using an asset allocation strategy designed for investors expected to retire around the year 2010.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The portfolio managers of the fund allocate assets among the underlying funds according to an asset allocation strategy that becomes increasingly conservative over time. John Hancock Multimanager 2010 Lifetime Portfolio has a target asset allocation of 38.75% of its assets in underlying funds that invest primarily in equity securities. The fund will have a greater exposure to underlying funds that invest primarily in fixed-income securities than will a John Hancock Multimanager Lifetime Portfolio with a more distant target date. To reduce investment risk and volatility as retirement approaches and in the postretirement years, the asset allocation strategy will change over time according to a predetermined "glide path" shown in the following chart. The fund may be a primary source of income for its shareholders after retirement.&lt;/div&gt;         
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                  GLIDE PATH CHART               
               &lt;/b&gt;&lt;/div&gt;    
 &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;/div&gt;         
                       &lt;img alt="glidepath chart" src="glidepath3.jpg"&gt;&lt;/img&gt;   
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The allocations reflected in the glide path are referred to as target allocations because they do not reflect active decisions made by the portfolio managers to produce an overweight or an underweight position in a particular asset class. The fund has a target allocation to underlying funds that invest in the broad asset classes of equity and fixed-income securities, but may also allocate its assets to underlying funds that invest outside these asset classes to protect the fund or help it achieve its objective. For example, the fund also typically allocates a portion of its assets to underlying funds that invest in alternative and specialty asset classes. The fund's allocation to alternative and specialty underlying funds may vary over time and in relation to a John Hancock Multimanager Lifetime Portfolio with a different target date. The managers may change the target allocation without shareholder approval if they believe that such change would benefit the fund and its shareholders. Under normal circumstances, any deviation from the target allocation is not expected to be greater than plus or minus 10%.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Within the prescribed percentage allocation, the managers select the percentage level to be maintained in specific underlying funds. New investments made by the fund may be directed to particular underlying funds in an effort to maintain the desired target allocations. There is no guarantee that the portfolio managers will correctly predict the market or economic conditions and, as with other mutual fund investments, you could lose money even if the fund is at or close to its designated retirement year or in its postretirement stage.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is designed for investors who may remain invested in the fund through their retirement years. The fund will continue to be managed according to an allocation strategy that becomes increasingly conservative over time until approximately twenty years after retirement, at which time the fund expects to maintain a static allocation of approximately 25% of its assets in equity underlying funds.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in underlying funds that invest in a broad range of equity, fixed-income and alternative/specialty securities and asset classes, including, but not limited to, U.S. and foreign securities, including emerging-market securities, commodities, asset-backed securities, small-cap securities, and below-investment-grade securities (i.e., junk bonds). The underlying funds may also use derivatives, such as swaps, foreign currency forwards, futures, and options, in each case for the purposes of reducing risk, obtaining efficient market exposure and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in various actively managed underlying funds that as a group hold a wide range of equity-type securities in their portfolios, including convertible securities. These include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. The fund may also invest in various passively managed underlying funds. Certain equity underlying funds may invest in initial public offerings (IPOs). Each of the equity underlying funds has its own investment strategy that, for example, may focus on growth stocks or value stocks, or may employ a strategy combining growth and income stocks, and/or may invest in derivatives such as credit default swaps, foreign currency forwards, interest rate swaps, options on securities, and futures contracts. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from shorter to longer term. The fixed-income underlying funds collectively hold various types of debt instruments such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging market securities). Certain underlying funds may invest in illiquid securities, and certain underlying funds may be non-diversified.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest directly in exchange-traded funds (ETFs), exchange-traded notes (ETNs), the securities of other investment companies, U.S. government securities, and other types of investments such as derivatives, including credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, in each case for the purposes of reducing risk, obtaining efficient market exposure, and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;To the extent permitted by law, the Board of Trustees of the fund may, in its discretion, determine to combine the fund with another fund without shareholder approval if the target allocation of the fund matches the target allocation of the other fund, although there is no assurance that the Board of Trustees will so determine at any point. The fund bears its own expenses and, in addition, indirectly bears its proportionate share of the expenses of the underlying funds in which it invests. The fund's performance reflects both the managers' allocation decisions and the performance of the underlying funds.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is subject to risks, and you could lose money by investing in the fund.  The principal risks of investing in the fund are listed below.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in fixed-income securities than John Hancock Multimanager Lifetime Portfolios with more distant target dates, fixed-income risks are more prevalent in this fund than in these other target date funds. In addition to fixed-income securities risk, the fund's other main risk factors are listed in alphabetical order.&lt;/div&gt;

                 &lt;i&gt; Principal risks of investing in the fund of funds   &lt;/i&gt;            
               &lt;/b&gt;&lt;/div&gt;             
                     
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk based on the nature of their support.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Investment company securities risk.&lt;/b&gt; A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lifecycle risk.&lt;/b&gt; Managers might not correctly predict market or economic conditions, and you could lose money even close to, during, or after the fund's designated retirement year.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Target allocation risk.&lt;/b&gt; The fund's risk profile will change due to reallocation or rebalancing of portfolio assets as the fund approaches its target date.&lt;/div&gt;

                &lt;i&gt;  Principal risks of investing in the underlying funds     &lt;/i&gt;          
               &lt;/b&gt;&lt;/div&gt;             
                     
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The following information illustrates the variability of the fund's returns and provides some indication of the risks of investing in the fund by showing changes in the fund's performance from year to year and by showing how the fund's average annual returns compared with a broad-based market index. Past performance (before and after taxes) does not indicate future results. All figures assume dividend reinvestment. Performance information is updated daily, monthly, and quarterly and may be obtained at our website, jhinvestments.com, or by calling 800-344-1029 between 8:00 A.M. and 7:00 P.M., Eastern time, on most business days.&lt;/div&gt;

The information shows how the fund's performance compares with the returns of an index of funds with similar investment objectives. From December 1, 2016 to November 30, 2017, the Custom Benchmark consisted of the following indices and approximate weightings: 28.88% Russell 3000 Index, 12.37% MSCI ACWI ex-USA Index, 47.00% Bloomberg Barclays U.S. Aggregate Bond Index, and 11.75% ICE Bank of America Merrill Lynch U.S. High Yield Master II Index. The weightings of the indices in the Custom Benchmark are adjusted annually to reflect changes in the fund's target asset allocation in accordance with the annual roll-down of the glide path described above and differed in periods prior to December 1, 2016.&lt;/div&gt;

Your actual after-tax returns may be different. After-tax returns are not relevant to shares held in an IRA, 401(k), or other tax-advantaged investment plan.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 17% of the average value of its portfolio.&lt;/div&gt;

The fund will have a greater exposure to underlying funds that invest primarily in fixed-income securities than will a John Hancock Multimanager Lifetime Portfolio with a more distant target date. To reduce investment risk and volatility as retirement approaches and in the postretirement years, the asset allocation strategy will change over time according to a predetermined "glide path" shown in the following chart. The fund may be a primary source of income for its shareholders after retirement.&lt;/div&gt;         
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                  GLIDE PATH CHART               
               &lt;/b&gt;&lt;/div&gt;         
 &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;/div&gt;    
                      &lt;img alt="glidepath chart" src="glidepath3.jpg"&gt;&lt;/img&gt;    
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The allocations reflected in the glide path are referred to as target allocations because they do not reflect active decisions made by the portfolio managers to produce an overweight or an underweight position in a particular asset class. The fund has a target allocation to underlying funds that invest in the broad asset classes of equity and fixed-income securities, but may also allocate its assets to underlying funds that invest outside these asset classes to protect the fund or help it achieve its objective. For example, the fund also typically allocates a portion of its assets to underlying funds that invest in alternative and specialty asset classes. The fund's allocation to alternative and specialty underlying funds may vary over time and in relation to a John Hancock Multimanager Lifetime Portfolio with a different target date. The managers may change the target allocation without shareholder approval if they believe that such change would benefit the fund and its shareholders. Under normal circumstances, any deviation from the target allocation is not expected to be greater than plus or minus 10%.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Within the prescribed percentage allocation, the managers select the percentage level to be maintained in specific underlying funds. New investments made by the fund may be directed to particular underlying funds in an effort to maintain the desired target allocations. There is no guarantee that the portfolio managers will correctly predict the market or economic conditions and, as with other mutual fund investments, you could lose money even if the fund is at or close to its designated retirement year or in its postretirement stage.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is designed for investors who may remain invested in the fund through their retirement years. The fund will continue to be managed according to an allocation strategy that becomes increasingly conservative over time until approximately twenty years after retirement, at which time the fund expects to maintain a static allocation of approximately 25% of its assets in equity underlying funds.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in underlying funds that invest in a broad range of equity, fixed-income and alternative/specialty securities and asset classes, including, but not limited to, U.S. and foreign securities, including emerging-market securities, commodities, asset-backed securities, small-cap securities, and below-investment-grade securities (i.e., junk bonds). The underlying funds may also use derivatives, such as swaps, foreign currency forwards, futures, and options, in each case for the purposes of reducing risk, obtaining efficient market exposure and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in various actively managed underlying funds that as a group hold a wide range of equity-type securities in their portfolios, including convertible securities. These include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. The fund may also invest in various passively managed underlying funds. Certain equity underlying funds may invest in initial public offerings (IPOs). Each of the equity underlying funds has its own investment strategy that, for example, may focus on growth stocks or value stocks, or may employ a strategy combining growth and income stocks, and/or may invest in derivatives such as credit default swaps, foreign currency forwards, interest rate swaps, options on securities, and futures contracts. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from shorter to longer term. The fixed-income underlying funds collectively hold various types of debt instruments such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging market securities). Certain underlying funds may invest in illiquid securities, and certain underlying funds may be non-diversified.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest directly in exchange-traded funds (ETFs), exchange-traded notes (ETNs), the securities of other investment companies, U.S. government securities, and other types of investments such as derivatives, including credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, in each case for the purposes of reducing risk, obtaining efficient market exposure, and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;To the extent permitted by law, the Board of Trustees of the fund may, in its discretion, determine to combine the fund with another fund without shareholder approval if the target allocation of the fund matches the target allocation of the other fund, although there is no assurance that the Board of Trustees will so determine at any point. The fund bears its own expenses and, in addition, indirectly bears its proportionate share of the expenses of the underlying funds in which it invests. The fund's performance reflects both the managers' allocation decisions and the performance of the underlying funds.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is subject to risks, and you could lose money by investing in the fund.  The principal risks of investing in the fund are listed below.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in fixed-income securities than John Hancock Multimanager Lifetime Portfolios with more distant target dates, fixed-income risks are more prevalent in this fund than in these other target date funds. In addition to fixed-income securities risk, the fund's other main risk factors are listed in alphabetical order.&lt;/div&gt;          
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                 &lt;i&gt; Principal risks of investing in the fund of funds   &lt;/i&gt;            
               &lt;/b&gt;&lt;/div&gt;             
                     
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk based on the nature of their support.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Investment company securities risk.&lt;/b&gt; A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lifecycle risk.&lt;/b&gt; Managers might not correctly predict market or economic conditions, and you could lose money even close to, during, or after the fund's designated retirement year.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Target allocation risk.&lt;/b&gt; The fund's risk profile will change due to reallocation or rebalancing of portfolio assets as the fund approaches its target date.&lt;/div&gt;         
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
              &lt;i&gt;    Principal risks of investing in the underlying funds    &lt;/i&gt;           
               &lt;/b&gt;&lt;/div&gt;             
                     
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;

               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;

               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;

               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;

               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;

               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

Past performance (before and after taxes) does not indicate future results. All figures assume dividend reinvestment. Performance information is updated daily, monthly, and quarterly and may be obtained at our website, jhinvestments.com, or by calling 800-344-1029 between 8:00 A.M. and 7:00 P.M., Eastern time, on most business days.&lt;/div&gt;

The information shows how the fund's performance compares with the returns of an index of funds with similar investment objectives. From December 1, 2016 to November 30, 2017, the Custom Benchmark consisted of the following indices and approximate weightings: 33.25% Russell 3000 Index, 14.25% MSCI ACWI ex-USA Index, 42.00% Bloomberg Barclays U.S. Aggregate Bond Index, and 10.50% ICE Bank of America Merrill Lynch U.S. High Yield Master II Index. The weightings of the indices in the Custom Benchmark are adjusted annually to reflect changes in the fund's target asset allocation in accordance with the annual roll-down of the glide path described above and differed in periods prior to December 1, 2016.&lt;/div&gt;

Please see below a hypothetical example showing the expenses of a $10,000 investment for the time periods indicated and then assuming you sell all of your shares at the end of those periods. The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 19% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests substantially all of its assets in underlying funds using an asset allocation strategy designed for investors expected to retire around the year 2020.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The portfolio managers of the fund allocate assets among the underlying funds according to an asset allocation strategy that becomes increasingly conservative over time. John Hancock Multimanager 2020 Lifetime Portfolio has a target asset allocation of 54% of its assets in underlying funds that invest primarily in equity securities. The fund will have a greater exposure to underlying funds that invest primarily in equity securities than will a John Hancock Multimanager Lifetime Portfolio with a closer target date. To reduce investment risk and volatility as retirement approaches and in the postretirement years, the asset allocation strategy will change over time according to a predetermined "glide path" shown in the following chart. The fund may be a primary source of income for its shareholders after retirement.&lt;/div&gt;         
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                  GLIDE PATH CHART               
               &lt;/b&gt;&lt;/div&gt;   
 &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;/div&gt;          
                     &lt;img alt="glidepath chart" src="glidepath3.jpg"&gt;&lt;/img&gt;     
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The allocations reflected in the glide path are referred to as target allocations because they do not reflect active decisions made by the portfolio managers to produce an overweight or an underweight position in a particular asset class. The fund has a target allocation to underlying funds that invest in the broad asset classes of equity and fixed-income securities, but may also allocate its assets to underlying funds that invest outside these asset classes to protect the fund or help it achieve its objective. For example, the fund also typically allocates a portion of its assets to underlying funds that invest in alternative and specialty asset classes. The fund's allocation to alternative and specialty underlying funds may vary over time and in relation to a John Hancock Multimanager Lifetime Portfolio with a different target date. The managers may change the target allocation without shareholder approval if they believe that such change would benefit the fund and its shareholders. Under normal circumstances, any deviation from the target allocation is not expected to be greater than plus or minus 10%.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Within the prescribed percentage allocation, the managers select the percentage level to be maintained in specific underlying funds. New investments made by the fund may be directed to particular underlying funds in an effort to maintain the desired target allocations. There is no guarantee that the portfolio managers will correctly predict the market or economic conditions and, as with other mutual fund investments, you could lose money even if the fund is at or close to its designated retirement year or in its postretirement stage.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is designed for investors who may remain invested in the fund through their retirement years. The fund will continue to be managed according to an allocation strategy that becomes increasingly conservative over time until approximately twenty years after retirement, at which time the fund expects to maintain a static allocation of approximately 25% of its assets in equity underlying funds.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in underlying funds that invest in a broad range of equity, fixed-income and alternative/specialty securities and asset classes, including, but not limited to, U.S. and foreign securities, including emerging-market securities, commodities, asset-backed securities, small-cap securities, and below-investment-grade securities (i.e., junk bonds). The underlying funds may also use derivatives, such as swaps, foreign currency forwards, futures, and options, in each case for the purposes of reducing risk, obtaining efficient market exposure and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in various actively managed underlying funds that as a group hold a wide range of equity-type securities in their portfolios, including convertible securities. These include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. The fund may also invest in various passively managed underlying funds. Certain equity underlying funds may invest in initial public offerings (IPOs). Each of the equity underlying funds has its own investment strategy that, for example, may focus on growth stocks or value stocks, or may employ a strategy combining growth and income stocks, and/or may invest in derivatives such as credit default swaps, foreign currency forwards, interest rate swaps, options on securities, and futures contracts. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from shorter to longer term. The fixed-income underlying funds collectively hold various types of debt instruments such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging market securities). Certain underlying funds may invest in illiquid securities, and certain underlying funds may be non-diversified.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest directly in exchange-traded funds (ETFs), exchange-traded notes (ETNs), the securities of other investment companies, U.S. government securities, and other types of investments such as derivatives, including credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, in each case for the purposes of reducing risk, obtaining efficient market exposure, and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;To the extent permitted by law, the Board of Trustees of the fund may, in its discretion, determine to combine the fund with another fund without shareholder approval if the target allocation of the fund matches the target allocation of the other fund, although there is no assurance that the Board of Trustees will so determine at any point. The fund bears its own expenses and, in addition, indirectly bears its proportionate share of the expenses of the underlying funds in which it invests. The fund's performance reflects both the managers' allocation decisions and the performance of the underlying funds.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in equity securities than John Hancock Multimanager Lifetime Portfolios with closer target dates, equity security risks are more prevalent in this fund than in these other target-date funds. In addition to equity securities risk, the fund's other main risk factors are listed in alphabetical order.&lt;/div&gt;

                 &lt;i&gt; Principal risks of investing in the fund of funds   &lt;/i&gt;            
               &lt;/b&gt;&lt;/div&gt;             
                     
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk based on the nature of their support.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;

               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;

               &lt;b&gt;Target allocation risk.&lt;/b&gt; The fund's risk profile will change due to reallocation or rebalancing of portfolio assets as the fund approaches its target date.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The following information illustrates the variability of the fund's returns and provides some indication of the risks of investing in the fund by showing changes in the fund's performance from year to year and by showing how the fund's average annual returns compared with a broad-based market index. Past performance (before and after taxes) does not indicate future results. All figures assume dividend reinvestment. Performance information is updated daily, monthly, and quarterly and may be obtained at our website, jhinvestments.com, or by calling 800-344-1029 between 8:00 A.M. and 7:00 P.M., Eastern time, on most business days.&lt;/div&gt;

The information shows how the fund's performance compares with the returns of an index of funds with similar investment objectives. From December 1, 2016 to November 30, 2017, the Custom Benchmark consisted of the following indices and approximate weightings: 40.60% Russell 3000 Index, 17.40% MSCI ACWI ex-USA Index, 33.60% Bloomberg Barclays U.S. Aggregate Bond Index, and 8.40% ICE Bank of America Merrill Lynch U.S. High Yield Master II Index. The weightings of the indices in the Custom Benchmark are adjusted annually to reflect changes in the fund's target asset allocation in accordance with the annual roll-down of the glide path described above and differed in periods prior to December 1, 2016.&lt;/div&gt;

The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 21% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests substantially all of its assets in underlying funds using an asset allocation strategy designed for investors expected to retire around the year 2025.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The portfolio managers of the fund allocate assets among the underlying funds according to an asset allocation strategy that becomes increasingly conservative over time. John Hancock Multimanager 2025 Lifetime Portfolio has a target asset allocation of 65% of its assets in underlying funds that invest primarily in equity securities. The fund will have a greater exposure to underlying funds that invest primarily in equity securities than will a John Hancock Multimanager Lifetime Portfolio with a closer target date. To reduce investment risk and volatility as retirement approaches and in the postretirement years, the asset allocation strategy will change over time according to a predetermined "glide path" shown in the following chart. The fund may be a primary source of income for its shareholders after retirement.&lt;/div&gt;         
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                  GLIDE PATH CHART               
               &lt;/b&gt;&lt;/div&gt;
 &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;/div&gt;             
                       &lt;img alt="glidepath chart" src="glidepath3.jpg"&gt;&lt;/img&gt;   
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The allocations reflected in the glide path are referred to as target allocations because they do not reflect active decisions made by the portfolio managers to produce an overweight or an underweight position in a particular asset class. The fund has a target allocation to underlying funds that invest in the broad asset classes of equity and fixed-income securities, but may also allocate its assets to underlying funds that invest outside these asset classes to protect the fund or help it achieve its objective. For example, the fund also typically allocates a portion of its assets to underlying funds that invest in alternative and specialty asset classes. The fund's allocation to alternative and specialty underlying funds may vary over time and in relation to a John Hancock Multimanager Lifetime Portfolio with a different target date. The managers may change the target allocation without shareholder approval if they believe that such change would benefit the fund and its shareholders. Under normal circumstances, any deviation from the target allocation is not expected to be greater than plus or minus 10%.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Within the prescribed percentage allocation, the managers select the percentage level to be maintained in specific underlying funds. New investments made by the fund may be directed to particular underlying funds in an effort to maintain the desired target allocations. There is no guarantee that the portfolio managers will correctly predict the market or economic conditions and, as with other mutual fund investments, you could lose money even if the fund is at or close to its designated retirement year or in its postretirement stage.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is designed for investors who may remain invested in the fund through their retirement years. The fund will continue to be managed according to an allocation strategy that becomes increasingly conservative over time until approximately twenty years after retirement, at which time the fund expects to maintain a static allocation of approximately 25% of its assets in equity underlying funds.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in underlying funds that invest in a broad range of equity, fixed-income and alternative/specialty securities and asset classes, including, but not limited to, U.S. and foreign securities, including emerging-market securities, commodities, asset-backed securities, small-cap securities, and below-investment-grade securities (i.e., junk bonds). The underlying funds may also use derivatives, such as swaps, foreign currency forwards, futures, and options, in each case for the purposes of reducing risk, obtaining efficient market exposure and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in various actively managed underlying funds that as a group hold a wide range of equity-type securities in their portfolios, including convertible securities. These include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. The fund may also invest in various passively managed underlying funds. Certain equity underlying funds may invest in initial public offerings (IPOs). Each of the equity underlying funds has its own investment strategy that, for example, may focus on growth stocks or value stocks, or may employ a strategy combining growth and income stocks, and/or may invest in derivatives such as credit default swaps, foreign currency forwards, interest rate swaps, options on securities, and futures contracts. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from shorter to longer term. The fixed-income underlying funds collectively hold various types of debt instruments such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging market securities). Certain underlying funds may invest in illiquid securities, and certain underlying funds may be non-diversified.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest directly in exchange-traded funds (ETFs), exchange-traded notes (ETNs), the securities of other investment companies, U.S. government securities, and other types of investments such as derivatives, including credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, in each case for the purposes of reducing risk, obtaining efficient market exposure, and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;To the extent permitted by law, the Board of Trustees of the fund may, in its discretion, determine to combine the fund with another fund without shareholder approval if the target allocation of the fund matches the target allocation of the other fund, although there is no assurance that the Board of Trustees will so determine at any point. The fund bears its own expenses and, in addition, indirectly bears its proportionate share of the expenses of the underlying funds in which it invests. The fund's performance reflects both the managers' allocation decisions and the performance of the underlying funds.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in equity securities than John Hancock Multimanager Lifetime Portfolios with closer target dates, equity security risks are more prevalent in this fund than in these other target-date funds. In addition to equity securities risk, the fund's other main risk factors are listed in alphabetical order.&lt;/div&gt;

               &lt;/b&gt;&lt;/div&gt;             
                     
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk based on the nature of their support.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;

               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;

               &lt;b&gt;Target allocation risk.&lt;/b&gt; The fund's risk profile will change due to reallocation or rebalancing of portfolio assets as the fund approaches its target date.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The following information illustrates the variability of the fund's returns and provides some indication of the risks of investing in the fund by showing changes in the fund's performance from year to year and by showing how the fund's average annual returns compared with a broad-based market index. Past performance (before and after taxes) does not indicate future results. All figures assume dividend reinvestment. Performance information is updated daily, monthly, and quarterly and may be obtained at our website, jhinvestments.com, or by calling 800-344-1029 between 8:00 A.M. and 7:00 P.M., Eastern time, on most business days.&lt;/div&gt;

The information shows how the fund's performance compares with the returns of an index of funds with similar investment objectives. From December 1, 2016 to November 30, 2017, the Custom Benchmark consisted of the following indices and approximate weightings: 49.00% Russell 3000 Index, 21.00% MSCI ACWI ex-USA Index, 24.00% Bloomberg Barclays U.S. Aggregate Bond Index, and 6.00% ICE Bank of America Merrill Lynch U.S. High Yield Master II Index. The weightings of the indices in the Custom Benchmark are adjusted annually to reflect changes in the fund's target asset allocation in accordance with the annual roll-down of the glide path described above and differed in periods prior to December 1, 2016.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 20% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests substantially all of its assets in underlying funds using an asset allocation strategy designed for investors expected to retire around the year 2030.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The portfolio managers of the fund allocate assets among the underlying funds according to an asset allocation strategy that becomes increasingly conservative over time. John Hancock Multimanager 2030 Lifetime Portfolio has a target asset allocation of 77% of its assets in underlying funds that invest primarily in equity securities. The fund will have a greater exposure to underlying funds that invest primarily in equity securities than will a John Hancock Multimanager Lifetime Portfolio with a closer target date. To reduce investment risk and volatility as retirement approaches and in the postretirement years, the asset allocation strategy will change over time according to a predetermined "glide path" shown in the following chart. The fund may be a primary source of income for its shareholders after retirement.&lt;/div&gt;         
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                  GLIDE PATH CHART               
               &lt;/b&gt;&lt;/div&gt;             
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;/div&gt;       
                     &lt;img alt="glidepath chart" src="glidepath3.jpg"&gt;&lt;/img&gt;  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The allocations reflected in the glide path are referred to as target allocations because they do not reflect active decisions made by the portfolio managers to produce an overweight or an underweight position in a particular asset class. The fund has a target allocation to underlying funds that invest in the broad asset classes of equity and fixed-income securities, but may also allocate its assets to underlying funds that invest outside these asset classes to protect the fund or help it achieve its objective. For example, the fund also typically allocates a portion of its assets to underlying funds that invest in alternative and specialty asset classes. The fund's allocation to alternative and specialty underlying funds may vary over time and in relation to a John Hancock Multimanager Lifetime Portfolio with a different target date. The managers may change the target allocation without shareholder approval if they believe that such change would benefit the fund and its shareholders. Under normal circumstances, any deviation from the target allocation is not expected to be greater than plus or minus 10%.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Within the prescribed percentage allocation, the managers select the percentage level to be maintained in specific underlying funds. New investments made by the fund may be directed to particular underlying funds in an effort to maintain the desired target allocations. There is no guarantee that the portfolio managers will correctly predict the market or economic conditions and, as with other mutual fund investments, you could lose money even if the fund is at or close to its designated retirement year or in its postretirement stage.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is designed for investors who may remain invested in the fund through their retirement years. The fund will continue to be managed according to an allocation strategy that becomes increasingly conservative over time until approximately twenty years after retirement, at which time the fund expects to maintain a static allocation of approximately 25% of its assets in equity underlying funds.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in underlying funds that invest in a broad range of equity, fixed-income and alternative/specialty securities and asset classes, including, but not limited to, U.S. and foreign securities, including emerging-market securities, commodities, asset-backed securities, small-cap securities, and below-investment-grade securities (i.e., junk bonds). The underlying funds may also use derivatives, such as swaps, foreign currency forwards, futures, and options, in each case for the purposes of reducing risk, obtaining efficient market exposure and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in various actively managed underlying funds that as a group hold a wide range of equity-type securities in their portfolios, including convertible securities. These include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. The fund may also invest in various passively managed underlying funds. Certain equity underlying funds may invest in initial public offerings (IPOs). Each of the equity underlying funds has its own investment strategy that, for example, may focus on growth stocks or value stocks, or may employ a strategy combining growth and income stocks, and/or may invest in derivatives such as credit default swaps, foreign currency forwards, interest rate swaps, options on securities, and futures contracts. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from shorter to longer term. The fixed-income underlying funds collectively hold various types of debt instruments such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging market securities). Certain underlying funds may invest in illiquid securities, and certain underlying funds may be non-diversified.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest directly in exchange-traded funds (ETFs), exchange-traded notes (ETNs), the securities of other investment companies, U.S. government securities, and other types of investments such as derivatives, including credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, in each case for the purposes of reducing risk, obtaining efficient market exposure, and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;To the extent permitted by law, the Board of Trustees of the fund may, in its discretion, determine to combine the fund with another fund without shareholder approval if the target allocation of the fund matches the target allocation of the other fund, although there is no assurance that the Board of Trustees will so determine at any point. The fund bears its own expenses and, in addition, indirectly bears its proportionate share of the expenses of the underlying funds in which it invests. The fund's performance reflects both the managers' allocation decisions and the performance of the underlying funds.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in equity securities than John Hancock Multimanager Lifetime Portfolios with closer target dates, equity security risks are more prevalent in this fund than in these other target-date funds. In addition to equity securities risk, the fund's other main risk factors are listed in alphabetical order.&lt;/div&gt;

               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk based on the nature of their support.&lt;/div&gt;

Similar incidents affecting issuers of a fund's securities may negatively impact performance.

               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;

               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;

               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;

               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;

               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;

               &lt;b&gt;Lifecycle risk.&lt;/b&gt; Managers might not correctly predict market or economic conditions, and you could lose money even close to, during, or after the fund's designated retirement year.&lt;/div&gt;

               &lt;b&gt;Target allocation risk.&lt;/b&gt; The fund's risk profile will change due to reallocation or rebalancing of portfolio assets as the fund approaches its target date.&lt;/div&gt;

               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;

               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;

               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

The information shows how the fund's performance compares with the returns of an index of funds with similar investment objectives. From December 1, 2016 to November 30, 2017, the Custom Benchmark consisted of the following indices and approximate weightings: 56.70% Russell 3000 Index, 24.30% MSCI ACWI ex-USA Index, 15.20% Bloomberg Barclays U.S. Aggregate Bond Index, and 3.80% ICE Bank of America Merrill Lynch U.S. High Yield Master II Index. The weightings of the indices in the Custom Benchmark are adjusted annually to reflect changes in the fund's target asset allocation in accordance with the annual roll-down of the glide path described above and differed in periods prior to December 1, 2016.&lt;/div&gt;

The example assumes a 5% average annual return and that fund expenses will not change over the periods.

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 19% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests substantially all of its assets in underlying funds using an asset allocation strategy designed for investors expected to retire around the year 2035.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The portfolio managers of the fund allocate assets among the underlying funds according to an asset allocation strategy that becomes increasingly conservative over time. John Hancock Multimanager 2035 Lifetime Portfolio has a target asset allocation of 86% of its assets in underlying funds that invest primarily in equity securities. The fund will have a greater exposure to underlying funds that invest primarily in equity securities than will a John Hancock Multimanager Lifetime Portfolio with a closer target date. To reduce investment risk and volatility as retirement approaches and in the postretirement years, the asset allocation strategy will change over time according to a predetermined "glide path" shown in the following chart. The fund may be a primary source of income for its shareholders after retirement.&lt;/div&gt;         
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                  GLIDE PATH CHART               
               &lt;/b&gt;&lt;/div&gt;             
                 &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;/div&gt;     
                     &lt;img alt="glidepath chart" src="glidepath3.jpg"&gt;&lt;/img&gt;  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The allocations reflected in the glide path are referred to as target allocations because they do not reflect active decisions made by the portfolio managers to produce an overweight or an underweight position in a particular asset class. The fund has a target allocation to underlying funds that invest in the broad asset classes of equity and fixed-income securities, but may also allocate its assets to underlying funds that invest outside these asset classes to protect the fund or help it achieve its objective. For example, the fund also typically allocates a portion of its assets to underlying funds that invest in alternative and specialty asset classes. The fund's allocation to alternative and specialty underlying funds may vary over time and in relation to a John Hancock Multimanager Lifetime Portfolio with a different target date. The managers may change the target allocation without shareholder approval if they believe that such change would benefit the fund and its shareholders. Under normal circumstances, any deviation from the target allocation is not expected to be greater than plus or minus 10%.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Within the prescribed percentage allocation, the managers select the percentage level to be maintained in specific underlying funds. New investments made by the fund may be directed to particular underlying funds in an effort to maintain the desired target allocations. There is no guarantee that the portfolio managers will correctly predict the market or economic conditions and, as with other mutual fund investments, you could lose money even if the fund is at or close to its designated retirement year or in its postretirement stage.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is designed for investors who may remain invested in the fund through their retirement years. The fund will continue to be managed according to an allocation strategy that becomes increasingly conservative over time until approximately twenty years after retirement, at which time the fund expects to maintain a static allocation of approximately 25% of its assets in equity underlying funds.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in underlying funds that invest in a broad range of equity, fixed-income and alternative/specialty securities and asset classes, including, but not limited to, U.S. and foreign securities, including emerging-market securities, commodities, asset-backed securities, small-cap securities, and below-investment-grade securities (i.e., junk bonds). The underlying funds may also use derivatives, such as swaps, foreign currency forwards, futures, and options, in each case for the purposes of reducing risk, obtaining efficient market exposure and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in various actively managed underlying funds that as a group hold a wide range of equity-type securities in their portfolios, including convertible securities. These include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. The fund may also invest in various passively managed underlying funds. Certain equity underlying funds may invest in initial public offerings (IPOs). Each of the equity underlying funds has its own investment strategy that, for example, may focus on growth stocks or value stocks, or may employ a strategy combining growth and income stocks, and/or may invest in derivatives such as credit default swaps, foreign currency forwards, interest rate swaps, options on securities, and futures contracts. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from shorter to longer term. The fixed-income underlying funds collectively hold various types of debt instruments such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging market securities). Certain underlying funds may invest in illiquid securities, and certain underlying funds may be non-diversified.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest directly in exchange-traded funds (ETFs), exchange-traded notes (ETNs), the securities of other investment companies, U.S. government securities, and other types of investments such as derivatives, including credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, in each case for the purposes of reducing risk, obtaining efficient market exposure, and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;To the extent permitted by law, the Board of Trustees of the fund may, in its discretion, determine to combine the fund with another fund without shareholder approval if the target allocation of the fund matches the target allocation of the other fund, although there is no assurance that the Board of Trustees will so determine at any point. The fund bears its own expenses and, in addition, indirectly bears its proportionate share of the expenses of the underlying funds in which it invests. The fund's performance reflects both the managers' allocation decisions and the performance of the underlying funds.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is subject to risks, and you could lose money by investing in the fund. The principal risks of investing in the fund are listed below.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in equity securities than John Hancock Multimanager Lifetime Portfolios with closer target dates, equity security risks are more prevalent in this fund than in these other target-date funds. In addition to equity securities risk, the fund's other main risk factors are listed in alphabetical order.&lt;/div&gt;

                 &lt;i&gt; Principal risks of investing in the fund of funds  &lt;/i&gt;             
               &lt;/b&gt;&lt;/div&gt;             
                     
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk based on the nature of their support.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Investment company securities risk.&lt;/b&gt; A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lifecycle risk.&lt;/b&gt; Managers might not correctly predict market or economic conditions, and you could lose money even close to, during, or after the fund's designated retirement year.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Target allocation risk.&lt;/b&gt; The fund's risk profile will change due to reallocation or rebalancing of portfolio assets as the fund approaches its target date.&lt;/div&gt;         
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The following information illustrates the variability of the fund's returns and provides some indication of the risks of investing in the fund by showing changes in the fund's performance from year to year and by showing how the fund's average annual returns compared with a broad-based market index. Past performance (before and after taxes) does not indicate future results. All figures assume dividend reinvestment. Performance information is updated daily, monthly, and quarterly and may be obtained at our website, jhinvestments.com, or by calling 800-344-1029 between 8:00 A.M. and 7:00 P.M., Eastern time, on most business days.&lt;/div&gt;

The information shows how the fund's performance compares with the returns of an index of funds with similar investment objectives. From December 1, 2016 to November 30, 2017, the Custom Benchmark consisted of the following indices and approximate weightings: 62.30% Russell 3000 Index, 26.70% MSCI ACWI ex-USA Index, 8.80% Bloomberg Barclays U.S. Aggregate Bond Index, and 2.20% ICE Bank of America Merrill Lynch U.S. High Yield Master II Index. The weightings of the indices in the Custom Benchmark are adjusted annually to reflect changes in the fund's target asset allocation in accordance with the annual roll-down of the glide path described above and differed in periods prior to December 1, 2016.&lt;/div&gt;

Your actual after-tax returns may be different. After-tax returns are not relevant to shares held in an IRA, 401(k), or other tax-advantaged investment plan.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 19% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests substantially all of its assets in underlying funds using an asset allocation strategy designed for investors expected to retire around the year 2040.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The portfolio managers of the fund allocate assets among the underlying funds according to an asset allocation strategy that becomes increasingly conservative over time. John Hancock Multimanager 2040 Lifetime Portfolio has a target asset allocation of 93% of its assets in underlying funds that invest primarily in equity securities. The fund will have a greater exposure to underlying funds that invest primarily in equity securities than will a John Hancock Multimanager Lifetime Portfolio with a closer target date. To reduce investment risk and volatility as retirement approaches and in the postretirement years, the asset allocation strategy will change over time according to a predetermined "glide path" shown in the following chart. The fund may be a primary source of income for its shareholders after retirement.&lt;/div&gt;         
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                  GLIDE PATH CHART               
               &lt;/b&gt;&lt;/div&gt;     
 &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;/div&gt;        
                        &lt;img alt="glidepath chart" src="glidepath3.jpg"&gt;&lt;/img&gt;  
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The allocations reflected in the glide path are referred to as target allocations because they do not reflect active decisions made by the portfolio managers to produce an overweight or an underweight position in a particular asset class. The fund has a target allocation to underlying funds that invest in the broad asset classes of equity and fixed-income securities, but may also allocate its assets to underlying funds that invest outside these asset classes to protect the fund or help it achieve its objective. For example, the fund also typically allocates a portion of its assets to underlying funds that invest in alternative and specialty asset classes. The fund's allocation to alternative and specialty underlying funds may vary over time and in relation to a John Hancock Multimanager Lifetime Portfolio with a different target date. The managers may change the target allocation without shareholder approval if they believe that such change would benefit the fund and its shareholders. Under normal circumstances, any deviation from the target allocation is not expected to be greater than plus or minus 10%.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Within the prescribed percentage allocation, the managers select the percentage level to be maintained in specific underlying funds. New investments made by the fund may be directed to particular underlying funds in an effort to maintain the desired target allocations. There is no guarantee that the portfolio managers will correctly predict the market or economic conditions and, as with other mutual fund investments, you could lose money even if the fund is at or close to its designated retirement year or in its postretirement stage.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is designed for investors who may remain invested in the fund through their retirement years. The fund will continue to be managed according to an allocation strategy that becomes increasingly conservative over time until approximately twenty years after retirement, at which time the fund expects to maintain a static allocation of approximately 25% of its assets in equity underlying funds.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in underlying funds that invest in a broad range of equity, fixed-income and alternative/specialty securities and asset classes, including, but not limited to, U.S. and foreign securities, including emerging-market securities, commodities, asset-backed securities, small-cap securities, and below-investment-grade securities (i.e., junk bonds). The underlying funds may also use derivatives, such as swaps, foreign currency forwards, futures, and options, in each case for the purposes of reducing risk, obtaining efficient market exposure and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in various actively managed underlying funds that as a group hold a wide range of equity-type securities in their portfolios, including convertible securities. These include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. The fund may also invest in various passively managed underlying funds. Certain equity underlying funds may invest in initial public offerings (IPOs). Each of the equity underlying funds has its own investment strategy that, for example, may focus on growth stocks or value stocks, or may employ a strategy combining growth and income stocks, and/or may invest in derivatives such as credit default swaps, foreign currency forwards, interest rate swaps, options on securities, and futures contracts. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from shorter to longer term. The fixed-income underlying funds collectively hold various types of debt instruments such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging market securities). Certain underlying funds may invest in illiquid securities, and certain underlying funds may be non-diversified.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest directly in exchange-traded funds (ETFs), exchange-traded notes (ETNs), the securities of other investment companies, U.S. government securities, and other types of investments such as derivatives, including credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, in each case for the purposes of reducing risk, obtaining efficient market exposure, and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;To the extent permitted by law, the Board of Trustees of the fund may, in its discretion, determine to combine the fund with another fund without shareholder approval if the target allocation of the fund matches the target allocation of the other fund, although there is no assurance that the Board of Trustees will so determine at any point. The fund bears its own expenses and, in addition, indirectly bears its proportionate share of the expenses of the underlying funds in which it invests. The fund's performance reflects both the managers' allocation decisions and the performance of the underlying funds.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is subject to risks, and you could lose money by investing in the fund. The principal risks of investing in the fund are listed below.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in equity securities than John Hancock Multimanager Lifetime Portfolios with closer target dates, equity security risks are more prevalent in this fund than in these other target-date funds. In addition to equity securities risk, the fund's other main risk factors are listed in alphabetical order.&lt;/div&gt;          
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                 &lt;i&gt; Principal risks of investing in the fund of funds &lt;/i&gt;              
               &lt;/b&gt;&lt;/div&gt;             
                     
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk based on the nature of their support.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Investment company securities risk.&lt;/b&gt; A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lifecycle risk.&lt;/b&gt; Managers might not correctly predict market or economic conditions, and you could lose money even close to, during, or after the fund's designated retirement year.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Target allocation risk.&lt;/b&gt; The fund's risk profile will change due to reallocation or rebalancing of portfolio assets as the fund approaches its target date.&lt;/div&gt;         
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                &lt;i&gt;  Principal risks of investing in the underlying funds     &lt;/i&gt;          
               &lt;/b&gt;&lt;/div&gt;             
                     
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;

               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;

               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;

               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;

               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;

               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;

               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The following information illustrates the variability of the fund's returns and provides some indication of the risks of investing in the fund by showing changes in the fund's performance from year to year and by showing how the fund's average annual returns compared with a broad-based market index. Past performance (before and after taxes) does not indicate future results. All figures assume dividend reinvestment. Performance information is updated daily, monthly, and quarterly and may be obtained at our website, jhinvestments.com, or by calling 800-344-1029 between 8:00 A.M. and 7:00 P.M., Eastern time, on most business days.&lt;/div&gt;

The information shows how the fund's performance compares with the returns of an index of funds with similar investment objectives. From December 1, 2007 to November 30, 2017, the Custom Benchmark consisted of the following indices and approximate weightings: 66.50% Russell 3000 Index, 28.50% MSCI ACWI ex-USA Index, 4.00% Bloomberg Barclays U.S. Aggregate Bond Index, and 1.00% ICE Bank of America Merrill Lynch U.S. High Yield Master II Index. The weightings of the indices in the Custom Benchmark are adjusted annually to reflect changes in the fund's target asset allocation in accordance with the annual roll-down of the glide path described above and differed in periods prior to December 1, 2007.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;This example is intended to help you compare the cost of investing in the fund with the cost of investing in other mutual funds. Please see below a hypothetical example showing the expenses of a $10,000 investment for the time periods indicated and then assuming you sell all of your shares at the end of those periods. The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 19% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests substantially all of its assets in underlying funds using an asset allocation strategy designed for investors expected to retire around the year 2045.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The portfolio managers of the fund allocate assets among the underlying funds according to an asset allocation strategy that becomes increasingly conservative over time. John Hancock Multimanager 2045 Lifetime Portfolio has a target asset allocation of 95% of its assets in underlying funds that invest primarily in equity securities. The fund will have a greater exposure to underlying funds that invest primarily in equity securities than will a John Hancock Multimanager Lifetime Portfolio with a closer target date. To reduce investment risk and volatility as retirement approaches and in the postretirement years, the asset allocation strategy will change over time according to a predetermined "glide path" shown in the following chart. The fund may be a primary source of income for its shareholders after retirement.&lt;/div&gt;          
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                  GLIDE PATH CHART               
               &lt;/b&gt;&lt;/div&gt;  
 &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;/div&gt;           
                        &lt;img alt="glidepath chart" src="glidepath3.jpg"&gt;&lt;/img&gt;  
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The allocations reflected in the glide path are referred to as target allocations because they do not reflect active decisions made by the portfolio managers to produce an overweight or an underweight position in a particular asset class. The fund has a target allocation to underlying funds that invest in the broad asset classes of equity and fixed-income securities, but may also allocate its assets to underlying funds that invest outside these asset classes to protect the fund or help it achieve its objective. For example, the fund also typically allocates a portion of its assets to underlying funds that invest in alternative and specialty asset classes. The fund's allocation to alternative and specialty underlying funds may vary over time and in relation to a John Hancock Multimanager Lifetime Portfolio with a different target date. The managers may change the target allocation without shareholder approval if they believe that such change would benefit the fund and its shareholders. Under normal circumstances, any deviation from the target allocation is not expected to be greater than plus or minus 10%.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Within the prescribed percentage allocation, the managers select the percentage level to be maintained in specific underlying funds. New investments made by the fund may be directed to particular underlying funds in an effort to maintain the desired target allocations. There is no guarantee that the portfolio managers will correctly predict the market or economic conditions and, as with other mutual fund investments, you could lose money even if the fund is at or close to its designated retirement year or in its postretirement stage.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is designed for investors who may remain invested in the fund through their retirement years. The fund will continue to be managed according to an allocation strategy that becomes increasingly conservative over time until approximately twenty years after retirement, at which time the fund expects to maintain a static allocation of approximately 25% of its assets in equity underlying funds.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in underlying funds that invest in a broad range of equity, fixed-income and alternative/specialty securities and asset classes, including, but not limited to, U.S. and foreign securities, including emerging-market securities, commodities, asset-backed securities, small-cap securities, and below-investment-grade securities (i.e., junk bonds). The underlying funds may also use derivatives, such as swaps, foreign currency forwards, futures, and options, in each case for the purposes of reducing risk, obtaining efficient market exposure and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in various actively managed underlying funds that as a group hold a wide range of equity-type securities in their portfolios, including convertible securities. These include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. The fund may also invest in various passively managed underlying funds. Certain equity underlying funds may invest in initial public offerings (IPOs). Each of the equity underlying funds has its own investment strategy that, for example, may focus on growth stocks or value stocks, or may employ a strategy combining growth and income stocks, and/or may invest in derivatives such as credit default swaps, foreign currency forwards, interest rate swaps, options on securities, and futures contracts. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from shorter to longer term. The fixed-income underlying funds collectively hold various types of debt instruments such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging market securities). Certain underlying funds may invest in illiquid securities, and certain underlying funds may be non-diversified.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest directly in exchange-traded funds (ETFs), exchange-traded notes (ETNs), the securities of other investment companies, U.S. government securities, and other types of investments such as derivatives, including credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, in each case for the purposes of reducing risk, obtaining efficient market exposure, and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;To the extent permitted by law, the Board of Trustees of the fund may, in its discretion, determine to combine the fund with another fund without shareholder approval if the target allocation of the fund matches the target allocation of the other fund, although there is no assurance that the Board of Trustees will so determine at any point. The fund bears its own expenses and, in addition, indirectly bears its proportionate share of the expenses of the underlying funds in which it invests. The fund's performance reflects both the managers' allocation decisions and the performance of the underlying funds.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is subject to risks, and you could lose money by investing in the fund. The principal risks of investing in the fund are listed below.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in equity securities than John Hancock Multimanager Lifetime Portfolios with closer target dates, equity security risks are more prevalent in this fund than in these other target-date funds. In addition to equity securities risk, the fund's other main risk factors are listed in alphabetical order.&lt;/div&gt;

                  &lt;i&gt;Principal risks of investing in the fund of funds      &lt;/i&gt;         
               &lt;/b&gt;&lt;/div&gt;             
                     
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk based on the nature of their support.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;

               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;

               &lt;b&gt;Target allocation risk.&lt;/b&gt; The fund's risk profile will change due to reallocation or rebalancing of portfolio assets as the fund approaches its target date.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The following information illustrates the variability of the fund's returns and provides some indication of the risks of investing in the fund by showing changes in the fund's performance from year to year and by showing how the fund's average annual returns compared with a broad-based market index. Past performance (before and after taxes) does not indicate future results. All figures assume dividend reinvestment. Performance information is updated daily, monthly, and quarterly and may be obtained at our website, jhinvestments.com, or by calling 800-344-1029 between 8:00 A.M. and 7:00 P.M., Eastern time, on most business days.&lt;/div&gt;

The information shows how the fund's performance compares with the returns of an index of funds with similar investment objectives. From December 1, 2007 to November 30, 2017, the Custom Benchmark consisted of the following indices and approximate weightings: 66.50% Russell 3000 Index, 28.50% MSCI ACWI ex-USA Index, 4.00% Bloomberg Barclays U.S. Aggregate Bond Index, and 1.00% ICE Bank of America Merrill Lynch U.S. High Yield Master II Index. The weightings of the indices in the Custom Benchmark are adjusted annually to reflect changes in the fund's target asset allocation in accordance with the annual roll-down of the glide path described above and differed in periods prior to December 1, 2007.&lt;/div&gt;

The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 18% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests substantially all of its assets in underlying funds using an asset allocation strategy designed for investors expected to retire around the year 2050.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The portfolio managers of the fund allocate assets among the underlying funds according to an asset allocation strategy that becomes increasingly conservative over time. John Hancock Multimanager 2050 Lifetime Portfolio has a target asset allocation of 95% of its assets in underlying funds that invest primarily in equity securities. The fund will have a greater exposure to underlying funds that invest primarily in equity securities than will a John Hancock Multimanager Lifetime Portfolio with a closer target date. To reduce investment risk and volatility as retirement approaches and in the postretirement years, the asset allocation strategy will change over time according to a predetermined "glide path" shown in the following chart. The fund may be a primary source of income for its shareholders after retirement.&lt;/div&gt;          
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                  GLIDE PATH CHART               
               &lt;/b&gt;&lt;/div&gt; 
 &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;/div&gt;            
                      &lt;img alt="glidepath chart" src="glidepath3.jpg"&gt;&lt;/img&gt;    
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The allocations reflected in the glide path are referred to as target allocations because they do not reflect active decisions made by the portfolio managers to produce an overweight or an underweight position in a particular asset class. The fund has a target allocation to underlying funds that invest in the broad asset classes of equity and fixed-income securities, but may also allocate its assets to underlying funds that invest outside these asset classes to protect the fund or help it achieve its objective. For example, the fund also typically allocates a portion of its assets to underlying funds that invest in alternative and specialty asset classes. The fund's allocation to alternative and specialty underlying funds may vary over time and in relation to a John Hancock Multimanager Lifetime Portfolio with a different target date. The managers may change the target allocation without shareholder approval if they believe that such change would benefit the fund and its shareholders. Under normal circumstances, any deviation from the target allocation is not expected to be greater than plus or minus 10%.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Within the prescribed percentage allocation, the managers select the percentage level to be maintained in specific underlying funds. New investments made by the fund may be directed to particular underlying funds in an effort to maintain the desired target allocations. There is no guarantee that the portfolio managers will correctly predict the market or economic conditions and, as with other mutual fund investments, you could lose money even if the fund is at or close to its designated retirement year or in its postretirement stage.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is designed for investors who may remain invested in the fund through their retirement years. The fund will continue to be managed according to an allocation strategy that becomes increasingly conservative over time until approximately twenty years after retirement, at which time the fund expects to maintain a static allocation of approximately 25% of its assets in equity underlying funds.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in underlying funds that invest in a broad range of equity, fixed-income and alternative/specialty securities and asset classes, including, but not limited to, U.S. and foreign securities, including emerging-market securities, commodities, asset-backed securities, small-cap securities, and below-investment-grade securities (i.e., junk bonds). The underlying funds may also use derivatives, such as swaps, foreign currency forwards, futures, and options, in each case for the purposes of reducing risk, obtaining efficient market exposure and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in various actively managed underlying funds that as a group hold a wide range of equity-type securities in their portfolios, including convertible securities. These include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. The fund may also invest in various passively managed underlying funds. Certain equity underlying funds may invest in initial public offerings (IPOs). Each of the equity underlying funds has its own investment strategy that, for example, may focus on growth stocks or value stocks, or may employ a strategy combining growth and income stocks, and/or may invest in derivatives such as credit default swaps, foreign currency forwards, interest rate swaps, options on securities, and futures contracts. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from shorter to longer term. The fixed-income underlying funds collectively hold various types of debt instruments such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging market securities). Certain underlying funds may invest in illiquid securities, and certain underlying funds may be non-diversified.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest directly in exchange-traded funds (ETFs), exchange-traded notes (ETNs), the securities of other investment companies, U.S. government securities, and other types of investments such as derivatives, including credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, in each case for the purposes of reducing risk, obtaining efficient market exposure, and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;To the extent permitted by law, the Board of Trustees of the fund may, in its discretion, determine to combine the fund with another fund without shareholder approval if the target allocation of the fund matches the target allocation of the other fund, although there is no assurance that the Board of Trustees will so determine at any point. The fund bears its own expenses and, in addition, indirectly bears its proportionate share of the expenses of the underlying funds in which it invests. The fund's performance reflects both the managers' allocation decisions and the performance of the underlying funds.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in equity securities than John Hancock Multimanager Lifetime Portfolios with closer target dates, equity security risks are more prevalent in this fund than in these other target-date funds. In addition to equity securities risk, the fund's other main risk factors are listed in alphabetical order.&lt;/div&gt;

                &lt;i&gt;  Principal risks of investing in the fund of funds   &lt;/i&gt;            
               &lt;/b&gt;&lt;/div&gt;             
                     
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk based on the nature of their support.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;

               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;

               &lt;/b&gt;&lt;/div&gt;

               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

The information shows how the fund's performance compares with the returns of an index of funds with similar investment objectives. From April 29, 2011 to November 30, 2017, the Custom Benchmark consisted of the following indices and approximate weightings: 66.50% Russell 3000 Index, 28.50% MSCI ACWI ex-USA Index, 4.00% Bloomberg Barclays U.S. Aggregate Bond Index, and 1.00% ICE Bank of America Merrill Lynch U.S. High Yield Master II Index. The weightings of the indices in the Custom Benchmark are adjusted annually to reflect changes in the fund's target asset allocation in accordance with the annual roll-down of the glide path described above.&lt;/div&gt;

The example assumes a 5% average annual return and that fund expenses will not change over the periods.

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 14% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests substantially all of its assets in underlying funds using an asset allocation strategy designed for investors expected to retire around the year 2055.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The portfolio managers of the fund allocate assets among the underlying funds according to an asset allocation strategy that becomes increasingly conservative over time. John Hancock Multimanager 2055 Lifetime Portfolio has a target asset allocation of 95% of its assets in underlying funds that invest primarily in equity securities. The fund will have a greater exposure to underlying funds that invest primarily in equity securities than will a John Hancock Multimanager Lifetime Portfolio with a closer target date. To reduce investment risk and volatility as retirement approaches and in the postretirement years, the asset allocation strategy will change over time according to a predetermined "glide path" shown in the following chart. The fund may be a primary source of income for its shareholders after retirement.&lt;/div&gt;          
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                  GLIDE PATH CHART               
               &lt;/b&gt;&lt;/div&gt;             
             &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;/div&gt;         
                     &lt;img alt="glidepath chart" src="glidepath3.jpg"&gt;&lt;/img&gt;  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The allocations reflected in the glide path are referred to as target allocations because they do not reflect active decisions made by the portfolio managers to produce an overweight or an underweight position in a particular asset class. The fund has a target allocation to underlying funds that invest in the broad asset classes of equity and fixed-income securities, but may also allocate its assets to underlying funds that invest outside these asset classes to protect the fund or help it achieve its objective. For example, the fund also typically allocates a portion of its assets to underlying funds that invest in alternative and specialty asset classes. The fund's allocation to alternative and specialty underlying funds may vary over time and in relation to a John Hancock Multimanager Lifetime Portfolio with a different target date. The managers may change the target allocation without shareholder approval if they believe that such change would benefit the fund and its shareholders. Under normal circumstances, any deviation from the target allocation is not expected to be greater than plus or minus 10%.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Within the prescribed percentage allocation, the managers select the percentage level to be maintained in specific underlying funds. New investments made by the fund may be directed to particular underlying funds in an effort to maintain the desired target allocations. There is no guarantee that the portfolio managers will correctly predict the market or economic conditions and, as with other mutual fund investments, you could lose money even if the fund is at or close to its designated retirement year or in its postretirement stage.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is designed for investors who may remain invested in the fund through their retirement years. The fund will continue to be managed according to an allocation strategy that becomes increasingly conservative over time until approximately twenty years after retirement, at which time the fund expects to maintain a static allocation of approximately 25% of its assets in equity underlying funds.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in underlying funds that invest in a broad range of equity, fixed-income and alternative/specialty securities and asset classes, including, but not limited to, U.S. and foreign securities, including emerging-market securities, commodities, asset-backed securities, small-cap securities, and below-investment-grade securities (i.e., junk bonds). The underlying funds may also use derivatives, such as swaps, foreign currency forwards, futures, and options, in each case for the purposes of reducing risk, obtaining efficient market exposure and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in various actively managed underlying funds that as a group hold a wide range of equity-type securities in their portfolios, including convertible securities. These include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. The fund may also invest in various passively managed underlying funds. Certain equity underlying funds may invest in initial public offerings (IPOs). Each of the equity underlying funds has its own investment strategy that, for example, may focus on growth stocks or value stocks, or may employ a strategy combining growth and income stocks, and/or may invest in derivatives such as credit default swaps, foreign currency forwards, interest rate swaps, options on securities, and futures contracts. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from shorter to longer term. The fixed-income underlying funds collectively hold various types of debt instruments such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging market securities). Certain underlying funds may invest in illiquid securities, and certain underlying funds may be non-diversified.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest directly in exchange-traded funds (ETFs), exchange-traded notes (ETNs), the securities of other investment companies, U.S. government securities, and other types of investments such as derivatives, including credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, in each case for the purposes of reducing risk, obtaining efficient market exposure, and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;To the extent permitted by law, the Board of Trustees of the fund may, in its discretion, determine to combine the fund with another fund without shareholder approval if the target allocation of the fund matches the target allocation of the other fund, although there is no assurance that the Board of Trustees will so determine at any point. The fund bears its own expenses and, in addition, indirectly bears its proportionate share of the expenses of the underlying funds in which it invests. The fund's performance reflects both the managers' allocation decisions and the performance of the underlying funds.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Because this fund has a greater exposure to underlying funds that invest primarily in equity securities than John Hancock Multimanager Lifetime Portfolios with closer target dates, equity security risks are more prevalent in this fund than in these other target-date funds. In addition to equity securities risk, the fund's other main risk factors are listed in alphabetical order.&lt;/div&gt;

               &lt;/b&gt;&lt;/div&gt;             
                     
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk based on the nature of their support.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;

               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;

               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;

               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;

               &lt;b&gt;Lifecycle risk.&lt;/b&gt; Managers might not correctly predict market or economic conditions, and you could lose money even close to, during, or after the fund's designated retirement year.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Target allocation risk.&lt;/b&gt; The fund's risk profile will change due to reallocation or rebalancing of portfolio assets as the fund approaches its target date.&lt;/div&gt;

               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that a fund may utilize include: credit default swaps, foreign currency forward contracts, futures contracts, interest-rate swaps, and options.

               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

The information shows how the fund's performance compares with the returns of an index of funds with similar investment objectives. From March 26, 2014 to November 30, 2017, the Custom Benchmark consisted of the following indices and approximate weightings: 66.50% Russell 3000 Index, 28.50% MSCI ACWI ex-USA Index, 4.00% Bloomberg Barclays U.S. Aggregate Bond Index, and 1.00% ICE Bank of America Merrill Lynch U.S. High Yield Master II Index. The weightings of the indices in the Custom Benchmark are adjusted annually to reflect changes in the fund's target asset allocation in accordance with the annual roll down of the glide path described above.&lt;/div&gt;

The example assumes a 5% average annual return and that fund expenses will not change over the periods.

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. A higher portfolio turnover rate may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 21% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests substantially all of its assets in underlying funds using an asset allocation strategy designed for investors expected to retire around the year 2060.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The portfolio managers of the fund allocate assets among the underlying funds according to an asset allocation strategy that becomes increasingly conservative over time. John Hancock Multimanager 2060 Lifetime Portfolio has a target asset allocation of 95% of its assets in underlying funds that invest primarily in equity securities. The fund will have a greater exposure to underlying funds that invest primarily in equity securities than will a John Hancock Multimanager Lifetime Portfolio with a closer target date. To reduce investment risk and volatility as retirement approaches and in the postretirement years, the asset allocation strategy will change over time according to a predetermined "glide path" shown in the following chart. The fund may be a primary source of income for its shareholders after retirement.&lt;/div&gt;          
                  
                     
                            
               &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;b&gt;                  
                  GLIDE PATH CHART               
               &lt;/b&gt;&lt;/div&gt;             
                      &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;&lt;/div&gt;
                  &lt;img alt="glidepath chart" src="glidepath3.jpg"&gt;&lt;/img&gt;  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The allocations reflected in the glide path are referred to as target allocations because they do not reflect active decisions made by the portfolio managers to produce an overweight or an underweight position in a particular asset class. The fund has a target allocation to underlying funds that invest in the broad asset classes of equity and fixed-income securities, but may also allocate its assets to underlying funds that invest outside these asset classes to protect the fund or help it achieve its objective. For example, the fund also typically allocates a portion of its assets to underlying funds that invest in alternative and specialty asset classes. The fund's allocation to alternative and specialty underlying funds may vary over time and in relation to a John Hancock Multimanager Lifetime Portfolio with a different target date. The managers may change the target allocation without shareholder approval if they believe that such change would benefit the fund and its shareholders. Under normal circumstances, any deviation from the target allocation is not expected to be greater than plus or minus 10%.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Within the prescribed percentage allocation, the managers select the percentage level to be maintained in specific underlying funds. New investments made by the fund may be directed to particular underlying funds in an effort to maintain the desired target allocations. There is no guarantee that the portfolio managers will correctly predict the market or economic conditions and, as with other mutual fund investments, you could lose money even if the fund is at or close to its designated retirement year or in its postretirement stage.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is designed for investors who may remain invested in the fund through their retirement years. The fund will continue to be managed according to an allocation strategy that becomes increasingly conservative over time until approximately twenty years after retirement, at which time the fund expects to maintain a static allocation of approximately 25% of its assets in equity underlying funds.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in underlying funds that invest in a broad range of equity, fixed-income and alternative/specialty securities and asset classes, including, but not limited to, U.S. and foreign securities, including emerging-market securities, commodities, asset-backed securities, small-cap securities, and below-investment-grade securities (i.e., junk bonds). The underlying funds may also use derivatives, such as swaps, foreign currency forwards, futures, and options, in each case for the purposes of reducing risk, obtaining efficient market exposure and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in various actively managed underlying funds that as a group hold a wide range of equity-type securities in their portfolios, including convertible securities. These include small-, mid-, and large-capitalization stocks, domestic and foreign securities (including emerging-market securities), and sector holdings. The fund may also invest in various passively managed underlying funds. Certain equity underlying funds may invest in initial public offerings (IPOs). Each of the equity underlying funds has its own investment strategy that, for example, may focus on growth stocks or value stocks, or may employ a strategy combining growth and income stocks, and/or may invest in derivatives such as credit default swaps, foreign currency forwards, interest rate swaps, options on securities, and futures contracts. Certain of the underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-investment-grade debt securities with maturities that range from shorter to longer term. The fixed-income underlying funds collectively hold various types of debt instruments such as corporate bonds and mortgage-backed, government-issued, domestic, and international securities (including emerging market securities). Certain underlying funds may invest in illiquid securities, and certain underlying funds may be non-diversified.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest directly in exchange-traded funds (ETFs), exchange-traded notes (ETNs), the securities of other investment companies, U.S. government securities, and other types of investments such as derivatives, including credit default swaps, options on equity index futures, interest-rate swaps, and foreign currency forward contracts, in each case for the purposes of reducing risk, obtaining efficient market exposure, and/or enhancing investment returns.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;To the extent permitted by law, the Board of Trustees of the fund may, in its discretion, determine to combine the fund with another fund without shareholder approval if the target allocation of the fund matches the target allocation of the other fund, although there is no assurance that the Board of Trustees will so determine at any point. The fund bears its own expenses and, in addition, indirectly bears its proportionate share of the expenses of the underlying funds in which it invests. The fund's performance reflects both the managers' allocation decisions and the performance of the underlying funds.&lt;/div&gt;

               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;

               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;

               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;

               &lt;b&gt;Exchange-traded notes risk.&lt;/b&gt; An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.&lt;/div&gt;

               &lt;b&gt;Fund of funds risk.&lt;/b&gt; The fund's ability to achieve its investment objective will depend largely, in part, on: (i) the underlying funds' performance, expenses and ability to meet their investment objectives; and (ii) properly rebalancing assets among underlying funds and different asset classes. The fund is also subject to risks related to: (i) layering of fees of the underlying funds; and (ii) conflicts of interest associated with the subadvisor's ability to allocate fund assets without limit to other funds it advises and/or other funds advised by affiliated subadvisors. There is no assurance that either the fund or the underlying funds will achieve their investment objectives. A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;

               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;

               &lt;b&gt;Lifecycle risk.&lt;/b&gt; Managers might not correctly predict market or economic conditions, and you could lose money even close to, during, or after the fund's designated retirement year.&lt;/div&gt;

               &lt;b&gt;Target allocation risk.&lt;/b&gt; The fund's risk profile will change due to reallocation or rebalancing of portfolio assets as the fund approaches its target date.&lt;/div&gt;

               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;

               &lt;b&gt;Commodity risk.&lt;/b&gt; Commodity prices may be volatile due to fluctuating demand, supply disruption, speculation, and other factors. Certain commodity investments may have no active trading market at times.&lt;/div&gt;

               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;

               &lt;b&gt;Illiquid and restricted securities risk.&lt;/b&gt; Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Initial public offerings risk.&lt;/b&gt; IPO share prices are frequently volatile and may significantly impact fund performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

The information shows how the fund's performance compares with the returns of an index of funds with similar investment objectives. From March 30, 2016 to November 30, 2017, the Custom Benchmark consisted of the following indices and approximate weightings: 66.50% Russell 3000 Index, 28.50% MSCI ACWI ex-USA Index, 4.00% Bloomberg Barclays U.S. Aggregate Bond Index, and 1.00% ICE Bank of America Merrill Lynch U.S. High Yield Master II Index. The weightings of the indices in the Custom Benchmark are adjusted annually to reflect changes in the fund's target asset allocation in accordance with the annual roll down of the glide path described above.&lt;/div&gt;

Please see below a hypothetical example showing the expenses of a $10,000 investment for the time periods indicated and then assuming you sell all of your shares at the end of those periods. The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's performance. During its most recent fiscal year, the fund's portfolio turnover rate was 52% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund invests primarily in equity securities of companies considered small-capitalization companies by the fund's managers. The fund also invests in mid-cap and micro-cap companies and reserves the right to invest in companies of any market-capitalization including large-cap companies. Market-capitalization classification is determined at the time of purchase by each manager using its own investment criteria. The market-capitalization of individual portfolio securities and the fund's portfolio as a whole will vary over time as market conditions change.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund invests in equity securities, including common stock, preferred stock and equity-equivalent securities or instruments whose values are based on common stocks, such as convertible securities, rights, warrants or options (stock or stock index), futures contracts (stock or stock index), and index swaps.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund employs a multi style and multi manager approach in which portions of the fund's assets are allocated to different managers that employ distinct investment styles. The fund currently has three managers. The fund's advisor provides or oversees the provision of all investment advisory and portfolio management services for the fund, including overseeing the investment allocation for the fund and managing the fund's overall portfolio characteristics, including investment style exposures.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The advisor selects managers for the fund, allocates fund assets among and oversees those managers, and evaluates their performance results. The managers select the individual portfolio securities for the assets assigned to them. The advisor considers various characteristics of the manager's portfolio when allocating assets: market capitalization, growth and profitability, valuation, sector weightings, and earnings and price volatility. The advisor also considers the correlation between the managers' historical and expected investment returns. Since the advisor will rebalance the fund only periodically, the actual portion of the fund managed by each manager at any given time will vary.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest in and potentially emphasize any economic sector. The fund may also invest in growth or value equity securities. Growth securities are securities a manager believes will experience relatively rapid earnings growth. Value securities, on the other hand, are securities a manager believes are selling at prices below their fundamental value.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund also may invest in: (a) securities of foreign issuers, including foreign issuers located in emerging markets, either directly through investments in foreign currency-denominated securities traded outside of the United States or indirectly through depositary receipts; (b) real estate investment trusts (REITs); (c) initial public offerings (IPOs); and (d) master limited partnerships (MLPs). The fund may invest in derivatives such as swaps, options, futures contracts, or options on futures contracts to gain market exposure, to adjust market exposure, or to maintain liquidity to pay redemptions. The fund may invest in foreign currency forward contracts to manage the fund's exposure to foreign currency. The fund also may invest in investment companies, including exchange-traded funds (ETFs) for the purpose of gaining exposure to equity markets while maintaining liquidity.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations.&lt;/div&gt;

               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Exchange-traded funds risk.&lt;/b&gt; An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.&lt;/div&gt;

               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: foreign currency forward contracts, futures contracts, options on futures, options, and swaps. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.&lt;/div&gt;

               &lt;b&gt;Large company risk.&lt;/b&gt; Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.&lt;/div&gt;

               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments.&lt;/div&gt;

               &lt;b&gt;Master limited partnership risk.&lt;/b&gt; MLPs generally reflect the risks associated with their underlying assets and with pooled investment vehicles. MLPs with credit-related holdings are subject to interest-rate risk and risk of default.&lt;/div&gt;

               &lt;b&gt;Multi manager risk.&lt;/b&gt; The management teams' investment styles may not complement each other as intended. A multi manager approach could result in more exposure to certain types of securities and higher portfolio turnover.&lt;/div&gt;

               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;

               &lt;b&gt;Real estate investment trust risk.&lt;/b&gt; REITs, pooled investment vehicles that typically invest in real estate directly or in loans collateralized by real estate, carry risks associated with owning real estate, including the potential for a decline in value due to economic or market conditions.&lt;/div&gt;

               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;

               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized (including microcap) companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

               &lt;b&gt;Warrants risk.&lt;/b&gt; The prices of warrants may not precisely reflect the prices of their underlying securities. Warrant holders do not receive dividends or have voting or credit rights. A warrant ceases to have value if not exercised prior to its expiration date.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The following information illustrates the variability of the fund's returns and provides some indication of the risks of investing in the fund by showing changes in the fund's performance from year to year and by showing how the fund's average annual returns compared with a broad-based market index. Past performance (before and after taxes) does not indicate future results. All figures assume dividend reinvestment. Performance information is updated daily, monthly, and quarterly and may be obtained at our website, jhinvestments.com, or by calling 800-344-1029 between 8:00 A.M. and 7:00 P.M., Eastern time, on most business days.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Prior to September 27, 2014, the fund was managed solely by Dimensional Fund Advisors LP and another subadvisor pursuant to a different investment strategy. The performance presented prior to this date should not be attributed to Brandywine Global Investment Management, LLC (Brandywine) or GW&amp;amp;K Investment Management, LLC (GW&amp;amp;K).&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Effective June 1, 2015, the fund eliminated its policy of investing at least 80% of its net assets (plus any borrowings for investment purposes) in equity securities of small capitalization companies and adopted other investment strategy changes. The performance information presented for periods prior to June 1, 2015, reflects management of the fund consistent with investment strategies in effect during those periods (and without Brandywine and GW&amp;amp;K) and might have been different if the fund's investments had been managed under its current investment strategies by all of its current managers.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Please note that after-tax returns reflect the highest individual federal marginal income-tax rate in effect as of the date provided and do not reflect any state or local taxes. Your actual after-tax returns may be different. After-tax returns are not relevant to shares held in an IRA, 401(k), or other tax-advantaged investment plan.&lt;/div&gt;

They are based on expenses incurred during the fund's most recent fiscal year expressed as a percentage of the fund's average net assets during the year. The fees and expenses do not reflect fees and expenses of any separate account that may use the fund as its underlying investment option and would be higher if they did.&lt;/div&gt;

Please see below a hypothetical example showing the expenses of a $10,000 investment for the time periods indicated and then assuming you sell all of your shares at the end of those periods. The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's performance. During its most recent fiscal year, the fund's portfolio turnover rate was 158% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in equity securities of real estate investment trusts ("REITs") and real estate companies. Equity securities include common stock, preferred stock and securities convertible into common stock.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;A company is considered to be a real estate company if, in the opinion of the manager, at least 50% of its revenues or 50% of the market value of its assets at the time its securities are purchased by the fund are attributed to the ownership, construction, management or sale of real estate.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The manager looks for real estate securities it believes will provide superior returns to the fund, and attempts to focus on companies with the potential for stock price appreciation and a record of paying dividends.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;To find these issuers, the manager tracks economic conditions and real estate market performance in major metropolitan areas and analyzes performance of various property types within those regions. To perform this analysis, it uses information from a nationwide network of real estate professionals to evaluate the holdings of real estate companies and REITs in which the fund may invest. Its analysis also includes the companies' management structure, financial structure and business strategy. The goal of these analyses is to determine which of the issuers the manager believes will be the most profitable to the fund. The manager also considers the effect of the real estate securities markets in general when making investment decisions. The manager does not attempt to time the market.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;A REIT invests primarily in income-producing real estate or makes loans to persons involved in the real estate industry.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Some REITs, called equity REITs, buy real estate and pay investors income from the rents received from the real estate owned by the REIT and from any profits on the sale of its properties. Other REITs, called mortgage REITs, lend money to building developers and other real estate companies and pay investors income from the interest paid on those loans. There are also hybrid REITs which engage in both owning real estate and making loans.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;If a REIT meets certain requirements, it is not taxed on the income it distributes to its investors.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may realize some short-term gains or losses if the manager chooses to sell a security because it believes that one or more of the following is true:&lt;/div&gt;            
            &lt;ul&gt;&lt;li&gt;                  
                  &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;A security is not fulfilling its investment purpose;&lt;/div&gt;               
               &lt;/li&gt;&lt;li&gt;                  
                  &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;A security has reached its optimum valuation; or&lt;/div&gt;               
               &lt;/li&gt;&lt;li&gt;                  
                  &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;A particular company or general economic conditions have changed.&lt;/div&gt;               
               &lt;/li&gt;&lt;/ul&gt;            
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Based on its recent practices, the manager expects that the fund's assets will be invested primarily in equity REITs. In changing market conditions, the fund may invest in other types of REITs.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;When the manager believes that it is prudent, the fund may invest a portion of its assets in other types of securities. These securities may include convertible securities, short-term securities, bonds, notes, securities of companies not principally engaged in the real estate industry, non-leveraged stock index futures contracts and other similar securities. (Stock index futures contracts, can help the fund's cash assets remain liquid while performing more like stocks.)&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest up to 10% of its total assets in securities of foreign real estate companies.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is a non-diversified fund, which means that it may invest in a smaller number of issuers than a diversified fund and may invest more of its assets in the securities of a single issuer.  The fund concentrates its investments in securities of issuers in the real estate industry.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is subject to risks, and you could lose money by investing in the fund. The principal risks of investing in the fund include:&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Concentration risk.&lt;/b&gt; Because the fund may focus on one or more industries or sectors of the economy, its performance depends in large part on the performance of those sectors or industries. As a result, the value of an investment may fluctuate more widely than it would in a fund that is diversified across industries and sectors. A downturn in the real estate industry may significantly detract from performance.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: futures contracts. Futures contracts generally are subject to counterparty risk.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;High portfolio turnover risk.&lt;/b&gt; Trading securities actively and frequently can increase transaction costs (thus lowering performance) and taxable distributions.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Non-diversified risk.&lt;/b&gt; Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Real estate investment trust risk.&lt;/b&gt; REITs, pooled investment vehicles that typically invest in real estate directly or in loans collateralized by real estate, carry risks associated with owning real estate, including the potential for a decline in value due to economic or market conditions.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Real estate securities risk.&lt;/b&gt; Securities of companies in the real estate industry carry risks associated with owning real estate, including the potential for a decline in value due to economic or market conditions.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;

A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's performance. During its most recent fiscal year, the fund's portfolio turnover rate was 46% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests at least 80% of its net assets (plus borrowings for investment purposes) in inflation-indexed bonds of varying maturities issued by the U.S. and foreign governments, their agencies or instrumentalities and corporations, which may be represented by forwards or derivatives such as options, futures contracts, or swap agreements.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Inflation-indexed bonds are fixed-income securities that are structured to provide protection against inflation. The value of the bond's principal or the interest income paid on the bond is adjusted to track changes in an official inflation measure. The U.S. Treasury uses the Consumer Price Index for Urban Consumers as the inflation measure. Inflation-indexed bonds issued by a foreign government are generally adjusted to reflect a comparable inflation index, calculated by that government. "Real return" equals total return less the estimated cost of inflation, which is typically measured by the change in an official inflation measure.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The types of fixed-income securities in which the fund may invest include the following securities which, unless otherwise noted, may be issued by domestic or foreign issuers and may be denominated in U.S. dollars or foreign currencies:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Fixed-income securities may have fixed, variable, or floating rates of interest, including rates of interest that vary inversely at a multiple of a designated or floating rate, or that vary according to change in relative values of currencies.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund invests primarily in investment-grade securities, but may invest up to 10% of its total assets in high yield securities ("junk bonds") rated B or higher by Moody's Investors Service, Inc. or equivalently rated by Standard and Poor's Ratings Services or Fitch Ratings Inc., or, if unrated, determined by the manager to be of comparable quality. The fund's investment policies are based on credit ratings at the time of purchase. The fund may also invest up to 30% of its total assets in securities denominated in foreign currencies, and may invest beyond this limit in U.S. dollar-denominated securities of foreign issuers. The fund may invest in baskets of foreign currencies (such as the euro) and direct currency. The fund will normally limit its foreign currency exposure (from foreign currency-denominated securities or foreign currencies) to 20% of its total assets. The fund may invest up to 10% of its total assets in securities and instruments that are economically tied to emerging market countries. This limitation does not apply to investment grade sovereign debt denominated in the local currency with less than 1 year remaining to maturity. The effective duration of this fund normally varies within three years (plus or minus) of the duration of the benchmark, as calculated by the manager.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest up to 10% of its total assets in preferred stocks.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may also lend its portfolio securities to brokers, dealers and other financial institutions to earn income. The fund may, without limitation, seek to obtain market exposure to the securities in which it primarily invests by entering into a series of purchase and sale contracts or by using other investment techniques (such as buy backs or dollar rolls).&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund's investment process may, at times, result in a higher than average portfolio turnover ratio and increased trading expenses.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may make short sales of a security including short sales "against the box."&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is subject to risks, and you could lose money by investing in the fund. The principal risks of investing in the fund include:&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Changing distribution levels risk.&lt;/b&gt; The fund may cease or reduce the level of its distribution if income or dividends paid from its investments declines.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Currency risk.&lt;/b&gt; Fluctuations in exchange rates may adversely affect the U.S. dollar value of a fund's investments. Foreign currencies may decline in value, which could negatively impact performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, foreign currency swaps, futures contracts, options on futures, interest-rate swaps, total return swaps, inverse floating-rate securities, swaps, options, and reverse repurchase agreements. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk. An event of default or insolvency of the counterparty to a reverse repurchase agreement could result in delays or restrictions with respect to the fund's ability to dispose of the underlying securities, in addition, a reverse repurchase agreement may be considered a form of leverage and may, therefore, increase fluctuations in the fund's net asset value per share (NAV).&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;High portfolio turnover risk.&lt;/b&gt; Trading securities actively and frequently can increase transaction costs (thus lowering performance) and taxable distributions.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hybrid instrument risk.&lt;/b&gt; Hybrid instruments entail greater market risk and may be more volatile than traditional debt instruments, may bear interest or pay preferred dividends at below-market rates, and may be illiquid. The risks of investing in hybrid instruments are a combination of the risks of investing in securities, options, futures, and currencies.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Inflation-linked security risk.&lt;/b&gt; Inflation-linked debt securities are subject to the effects of changes in market interest rates caused by factors other than inflation (real interest rates). In general, the price of an inflation-linked security tends to decline when real interest rates increase. Unlike conventional bonds, the principal and interest payments of inflation-linked securities such as TIPS are adjusted periodically to a specified rate of inflation (e.g., Non-Seasonally Adjusted Consumer Price Index for all Urban Consumers (CPI-U)). There can be no assurance that the inflation index used will accurately measure the real rate of inflation. These securities may lose value in the event that the actual rate of inflation is different than the rate of the inflation index.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Loan participations risk.&lt;/b&gt; Participations and assignments involve special types of risks, including credit risk, interest-rate risk, counterparty risk, liquidity risk, risks associated with extended settlement, and the risks of being a lender.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Mortgage-backed and asset-backed securities risk. &lt;/b&gt; Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Municipal bond risk.&lt;/b&gt; The prices of municipal bonds, including general obligation bonds, can decline if the issuer's credit quality declines. Revenue bond prices can decline if related projects become unprofitable. An insured municipal bond is subject to the risk that the insurer may be unable to pay claims and is not insured with respect to the market value of the obligation. Municipal bond income could become taxable in the future. Investments in AMT bonds may result in tax liability for shareholders.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Short sales risk.&lt;/b&gt; In a short sale, a fund pays interest on the borrowed security. The fund will lose money if the security price increases between the short sale and the replacement date.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;

Past performance (before and after taxes) does not indicate future results. All figures assume dividend reinvestment. Performance information is updated daily, monthly, and quarterly and may be obtained at our website, jhinvestments.com, or by calling 800-344-1029 between 8:00 A.M. and 7:00 P.M., Eastern time, on most business days.&lt;/div&gt;

The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's performance. During its most recent fiscal year, the fund's portfolio turnover rate was 31% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in companies with market capitalizations, at the time of investment, that do not exceed the maximum market capitalization of any security in the Russell 2000 Index ($13.0 million to $6.3 billion as of October 31, 2018).&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund invests in small companies whose common stocks are believed to be undervalued. The market capitalization of the companies in the fund's portfolio and the Russell 2000 Index changes over time, and the fund will not sell a stock just because the company has grown to a market capitalization outside the range. The fund may, on occasion, purchase companies with a market capitalization above the range.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Reflecting a value approach to investing, the fund will seek the stocks of companies whose current stock prices do not appear to adequately reflect their underlying value as measured by assets, earnings, cash flow, or business franchises. The manager's in-house research team seeks to identify companies that appear to be undervalued by various measures, and may be temporarily out of favor, but have good prospects for capital appreciation. In selecting investments, they generally look for some of the following factors:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;While most assets will be invested in U.S. common stocks, including real estate investment trusts (REITs) that pool money to invest in properties and mortgages, the fund may purchase other securities, including foreign securities (up to 20% of its total assets), futures, and options. The fund may invest in fixed-income and convertible securities without restrictions on quality or rating, including up to 10% of total assets in below-investment-grade fixed-income securities ("junk bonds"). The fund's fixed income investments may include privately negotiated notes or loans, including loan participations and assignments ("bank loans"). These investments in bank loans will be made only in companies, municipalities or entities that meet the fund's investment criteria. Some loans may be illiquid. Since the fund invests primarily in equity securities, the risks associated with fixed-income securities will not affect the fund as much as they would a fund that invests more of its assets in fixed-income securities.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund holds a certain portion of its assets in money market reserves which can consist of shares of the T. Rowe Price Government Reserve Fund (or any other internal T. Rowe Price money market fund) as well as U.S. and foreign currency denominated money market securities, including repurchase agreements, in the two highest rating categories, maturing in one year or less. The fund may invest reserves in U.S. dollars and foreign currencies.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may sell securities for a variety of reasons, such as to secure gains, limit losses or redeploy assets into more promising opportunities.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund may invest up to 10% of its total assets in hybrid instruments. Hybrid instruments are a type of high-risk derivatives which can combine the characteristics of securities, futures and options. Such securities may bear interest or pay dividends at below (or even relatively nominal) rates. The fund may also invest in options and enter into futures contracts. The fund may at times invest significantly in certain sectors, such as the financials sector.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund is subject to risks, and you could lose money by investing in the fund. The principal risks of investing in the fund include:&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Convertible securities risk.&lt;/b&gt; The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. As the market price of underlying common stock declines below the conversion price, the market value of the convertible security tends to be increasingly influenced by its yield.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Credit and counterparty risk.&lt;/b&gt; The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. A downgrade or default affecting any of the fund's securities could affect the fund's performance.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Currency risk.&lt;/b&gt; Fluctuations in exchange rates may adversely affect the U.S. dollar value of a fund's investments. Foreign currencies may decline in value, which could negatively impact performance.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Cybersecurity and operational risk.&lt;/b&gt; Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Economic and market events risk.&lt;/b&gt; Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Equity securities risk.&lt;/b&gt; The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Foreign securities risk.&lt;/b&gt; Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hedging, derivatives, and other strategic transactions risk.&lt;/b&gt; Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivatives transactions. Derivatives and other strategic transactions that the fund intends to utilize include: futures contracts and options. Futures contracts and options generally are subject to counterparty risk.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Hybrid instrument risk.&lt;/b&gt; Hybrid instruments entail greater market risk and may be more volatile than traditional debt instruments, may bear interest or pay preferred dividends at below-market rates, and may be illiquid. The risks of investing in hybrid instruments are a combination of the risks of investing in securities, options, futures, and currencies.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Investment company securities risk.&lt;/b&gt; A fund bears underlying fund fees and expenses indirectly.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Loan participations risk.&lt;/b&gt; Participations and assignments involve special types of risks, including credit risk, interest-rate risk, counterparty risk, liquidity risk, risks associated with extended settlement, and the risks of being a lender.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Real estate investment trust risk.&lt;/b&gt; REITs, pooled investment vehicles that typically invest in real estate directly or in loans collateralized by real estate, carry risks associated with owning real estate, including the potential for a decline in value due to economic or market conditions.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Real estate securities risk.&lt;/b&gt; Securities of companies in the real estate industry carry risks associated with owning real estate, including the potential for a decline in value due to economic or market conditions.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors. To the extent that a fund invests in securities of companies in the financial services sector, the fund may be significantly affected by economic, market, and business developments, borrowing costs, interest-rate fluctuations, competition, and government regulation, among other factors, impacting that sector.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Small and mid-sized company risk.&lt;/b&gt; Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Value investing style risk.&lt;/b&gt; The fund emphasizes a value style of investing, which focuses on undervalued companies with characteristics for improved valuations. This style of investing is subject to the risk that the valuations never improve or that the returns on value equity securities are less than returns on other styles of investing or the overall stock market. Value stocks also may decline in price, even though in theory they are already underpriced.&lt;/div&gt;

Please see below a hypothetical example showing the expenses of a $10,000 investment for the time periods indicated and then assuming you sell all of your shares at the end of those periods. The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's performance. During its most recent fiscal year, the fund's portfolio turnover rate was 51% of the average value of its portfolio.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal market conditions, the fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in U.S. corporate debt securities that are, at the time of investment, below investment grade, including preferred and other convertible securities in below-investment-grade debt securities (sometimes referred to as "junk bonds" or high yield securities). The fund also invests in corporate debt securities that are investment grade, and may buy preferred and other convertible securities and bank loans that are investment grade. Some loans may be illiquid.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The manager actively manages a diversified portfolio of below-investment-grade debt securities. The manager does not manage the portfolio to a specific maturity or duration. The manager focuses on individual security selection (primarily using a "bottom-up" approach) and seeks to identify high yield securities that appear comparatively undervalued. The manager uses its knowledge of various industries to assess the risk/return tradeoff among issuers within particular industries, in seeking to identify compelling relative value investments. The manager analyzes the issuers' long-term prospects and focuses on characteristics such as management, asset coverage, free cash flow generation, liquidity and business risk. The manager's research and analysis highlights industry drivers, competitive position and operating trends with an emphasis on free cash flow. The manager also talks to management, and consults industry contacts, debt and equity analysts, and rating agencies.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The manager purchases securities for the fund when attractive risk/reward ideas are identified and sells securities when either the securities become overvalued or circumstances change in a way that adversely affects this risk/return profile. Rigorous credit analysis of individual issuers is an integral part of the selection process. The manager attempts to invest in high yield securities of issuers which it believes have ample asset coverage for their debt securities in comparison to other high yield security issuers in an effort to minimize default risk and maximize risk-adjusted returns. The strategy is focused on selecting investments that can capture the significant current income and capital appreciation potential of the high yield market while also managing downside risk. The total return sought by the fund consists of income earned on the fund's investments, together with the appreciation that may result from decreases in interest rates or improving credit fundamentals for a particular industry or issuer. The fund may invest significantly in issuers in the communications sector.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Under normal circumstances, the manager invests:&lt;/div&gt;            
            &lt;ul&gt;&lt;li&gt;                  
                  &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Up to 15% of total assets in any one industry; and&lt;/div&gt;               
               &lt;/li&gt;&lt;li&gt;                  
                  &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;Up to 5% of total assets in any one issuer (excluding investments in cash-equivalent issuers or for cash-management purposes).&lt;/div&gt;               
               &lt;/li&gt;&lt;/ul&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The manager will generally invest in below investment grade debt securities that are rated at least "Caa" by Moody's Investors Service, Inc. or "CCC" by Standard and Poor's Ratings Services, or that are unrated but deemed by the manager to be of comparable quality but may also invest in securities rated below these ratings (or unrated securities of comparable quality). The average credit quality of the fund's securities is expected to be at least B- as rated by Standard and Poor's Ratings Services.&lt;/div&gt;             
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;The fund's investment process may, at times, result in a higher than average portfolio turnover ratio and increased trading expenses.&lt;/div&gt;

Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.&lt;/div&gt;

            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Fixed-income securities risk.&lt;/b&gt; A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;High portfolio turnover risk.&lt;/b&gt; Trading securities actively and frequently can increase transaction costs (thus lowering performance) and taxable distributions.&lt;/div&gt;         
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Liquidity risk.&lt;/b&gt; The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Loan participations risk.&lt;/b&gt; Participations and assignments involve special types of risks, including credit risk, interest-rate risk, counterparty risk, liquidity risk, risks associated with extended settlement, and the risks of being a lender.&lt;/div&gt;          
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Lower-rated and high-yield fixed-income securities risk.&lt;/b&gt; Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Preferred and convertible securities risk.&lt;/b&gt; Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.&lt;/div&gt;         
                  
                      
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Sector risk.&lt;/b&gt; When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.&lt;/div&gt;          
                  
                     
            &lt;div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"&gt;               
               &lt;b&gt;Technology companies risk.&lt;/b&gt; Technology companies can be significantly affected by rapid obsolescence, short product cycles, competition, and government regulation, among other factors. Investments in the technology sector may be susceptible to heightened risk of cybersecurity breaches, which may allow an unauthorized party to gain access to personally identifiable information and other customer data.&lt;/div&gt;

            The advisor contractually agrees to waive a portion of its management fee and/or reimburse expenses for the fund and certain other John Hancock funds according to an asset level breakpoint schedule that is based on the aggregate net assets of all the funds participating in the waiver or reimbursement. This waiver is allocated proportionally among the participating funds. During its most recent fiscal year, the fund's reimbursement amounted to 0.01% of the fund's average daily net assets. This agreement expires on June 30, 2020, unless renewed by mutual agreement of the fund and the advisor based upon a determination that this is appropriate under the circumstances at that time.

            The advisor contractually agrees to reduce its management fee or, if necessary, make payment to the fund in an amount equal to the amount by which expenses of the fund exceed 0.74% of average daily net assets of the fund. For purposes of this agreement, "expenses of the fund" means all fund expenses, excluding (a) taxes, (b) brokerage commissions, (c) interest expense, (d) litigation and indemnification expenses and other extraordinary expenses not incurred in the ordinary course of the Fund's business, (e) class specific expenses, (f) underlying fund expenses (acquired fund fees), (g) borrowing costs, (h) prime brokerage fees, and (i) short dividend expense. This agreement expires on December 31, 2019, unless renewed by mutual agreement of the fund and the advisor based upon a determination that this is appropriate under the circumstances at that time. The advisor also contractually agrees to waive a portion of its management fee and/or reimburse expenses for the fund and certain other John Hancock funds according to an asset level breakpoint schedule that is based on the aggregate net assets of all the funds participating in the waiver or reimbursement. This waiver is allocated proportionally among the participating funds. During its most recent fiscal year, the fund's reimbursement amounted to 0.01% of the fund's average daily net assets. This agreement expires on June 30, 2020, unless renewed by mutual agreement of the fund and the advisor based upon a determination that this is appropriate under the circumstances at that time.

            The advisor contractually agrees to reduce its management fee or, if necessary, make payment to the fund in an amount equal to the amount by which other expenses of the fund exceed 0.05% of the average daily net assets of the fund. For purposes of this agreement, "other expenses of the fund" means all fund expenses, excluding: (a) advisory fees, (b) taxes, (c) brokerage commissions, (d) interest expense, (e) litigation and indemnification expenses and other extraordinary expenses not incurred in the ordinary course of the fund's business, (f) class specific expenses, (g) underlying fund expenses (acquired fund fees), and (h) short dividend expense. This agreement expires on December 31, 2019, unless renewed by mutual agreement of the fund and the advisor based upon a determination that this is appropriate under the circumstances at that time.

            The advisor contractually agrees to reduce its management fee or, if necessary, make payment to the fund in an amount equal to the amount by which other expenses of the fund exceed 0.05% of the average daily net assets of the fund. For purposes of this agreement, "other expenses of the fund" means all fund expenses, excluding: (a) advisory fees, (b) taxes, (c) brokerage commissions, (d) interest expense, (e) litigation and indemnification expenses and other extraordinary expenses not incurred in the ordinary course of the fund's business, (f) class specific expenses, (g) underlying fund expenses (acquired fund fees), and (h) short dividend expense. This agreement expires on December 31, 2019, unless renewed by mutual agreement of the fund and the advisor based upon a determination that this is appropriate under the circumstances at that time.

            The advisor contractually agrees to reduce its management fee or, if necessary, make payment to Class A shares in an amount equal to the amount by which expenses of Class A shares exceed 1.39% of average daily net assets attributable to the class. For purposes of this agreement, "expenses of Class A shares" means all expenses of the class (including fund expenses attributable to the class), excluding (a) taxes, (b) brokerage commissions, (c) interest expense, (d) litigation and indemnification expenses and other extraordinary expenses not incurred in the ordinary course of the fund's business, (e) underlying fund expenses (acquired fund fees), and (f) short dividend expense. This agreement expires on December 31, 2019, unless renewed by mutual agreement of the fund and the advisor based upon a determination that this is appropriate under the circumstances at that time. The advisor also contractually agrees to waive a portion of its management fee and/or reimburse expenses for the fund and certain other John Hancock funds according to an asset level breakpoint schedule that is based on the aggregate net assets of all the funds participating in the waiver or reimbursement. This waiver is allocated proportionally among the participating funds. During its most recent fiscal year, the fund's reimbursement amounted to 0.01% of the fund's average daily net assets. This agreement expires on June 30, 2020, unless renewed by mutual agreement of the fund and the advisor based upon a determination that this is appropriate under the circumstances at that time.

            The advisor contractually agrees to reduce its management fee or, if necessary, make payment to the fund in an amount equal to the amount by which expenses of the fund exceed 0.66% of average daily net assets of the fund and expenses of Class A, Class B, Class C, Class I and Class R6 shares, as applicable, exceed 1.00%, 1.75%, 1.75%, 0.77% and 0.66%, respectively, of average daily net assets attributable to the applicable class. For purposes of these agreements, "expenses of the fund" means all fund expenses, excluding (a) taxes, (b) brokerage commissions, (c) interest expense, (d) litigation and indemnification expenses and other extraordinary expenses not incurred in the ordinary course of the fund's business, (e) class-specific expenses, (f) acquired fund fees and expenses paid indirectly, (g) borrowing costs, (h) prime brokerage fees, and (i) short dividend expense; and "expenses of Class A, Class B, Class C, Class I and Class R6 shares" means all expenses of the fund (as defined above) attributable to the applicable class plus class-specific expenses. These agreements expire on December 31, 2019, unless renewed by mutual agreement of the fund and the advisor based upon a determination that this is appropriate under the circumstances at that time. The advisor also contractually agrees to waive a portion of its management fee and/or reimburse expenses for the fund and certain other John Hancock funds according to an asset level breakpoint schedule that is based on the aggregate net assets of all the funds participating in the waiver or reimbursement. This waiver is allocated proportionally among the participating funds. During its most recent fiscal year, the fund's reimbursement amounted to 0.01% of the fund's average daily net assets. This agreement expires on June 30, 2020, unless renewed by mutual agreement of the fund and the advisor based upon a determination that this is appropriate under the circumstances at that time.

            The advisor contractually agrees to reduce its management fee or, if necessary, make payment to the fund in an amount equal to the amount by which other expenses of the fund exceed 0.05% of the average daily net assets of the fund.

            The advisor contractually agrees to reduce its management fee or, if necessary, make payment to the fund in an amount equal to the amount by which expenses of the fund exceed 0.66% of average daily net assets of the fund and expenses of Class 1 shares exceed 0.70% of average daily net assets attributable to the class. For purposes of these agreements, "expenses of the fund" means all fund expenses, excluding (a) taxes, (b) brokerage commissions, (c) interest expense, (d) litigation and indemnification expenses and other extraordinary expenses not incurred in the ordinary course of the fund's business, (e) class-specific expenses, (f) acquired fund fees and expenses paid indirectly, (g) borrowing costs, (h) prime brokerage fees, and (i) short dividend expense; and "expenses of Class 1 shares" means all expenses of the fund (as defined above) attributable to the class plus class-specific expenses. These agreements expire on December 31, 2019, unless renewed by mutual agreement of the fund and the advisor based upon a determination that this is appropriate under the circumstances at that time. The advisor also contractually agrees to waive a portion of its management fee and/or reimburse expenses for the fund and certain other John Hancock funds according to an asset level breakpoint schedule that is based on the aggregate net assets of all the funds participating in the waiver or reimbursement. This waiver is allocated proportionally among the participating funds. During its most recent fiscal year, the fund's reimbursement amounted to 0.01% of the fund's average daily net assets. This agreement expires on June 30, 2020, unless renewed by mutual agreement of the fund and the advisor based upon a determination that this is appropriate under the circumstances at that time.

            The advisor contractually agrees to waive its management fee so that the amount retained by the advisor after payment of subadvisory fees does not exceed 0.45% of the fund's average daily net assets. The advisor also contractually agrees to reduce its management fee or, if necessary, make payment to the fund in an amount equal to the amount by which expenses of the fund exceed 0.79% of average daily net assets of the fund. For purposes of this agreement, "expenses of the fund" means all expenses of the fund (as defined above) plus class-specific expenses. These agreements expire on December 31, 2019, unless renewed by mutual agreement of the fund and the advisor based upon a determination that this is appropriate under the circumstances at that time. The advisor also contractually agrees to waive a portion of its management fee and/or reimburse expenses for the fund and certain other John Hancock funds according to an asset level breakpoint schedule that is based on the aggregate net assets of all the funds participating in the waiver or reimbursement. This waiver is allocated proportionally among the participating funds. During its most recent fiscal year, the fund's reimbursement amounted to 0.01% of the fund's average daily net assets. This agreement expires on June 30, 2020, unless renewed by mutual agreement of the fund and the advisor based upon a determination that this is appropriate under the circumstances at that time.

This waiver is allocated proportionally among the participating funds. During its most recent fiscal year, the fund's reimbursement amounted to 0.01% of the fund's average daily net assets. This agreement expires on June 30, 2020, unless renewed by mutual agreement of the fund and the advisor based upon a determination that this is appropriate under the circumstances at that time.

            The advisor contractually agrees to reduce its management fee or, if necessary, make payment to the fund in an amount equal to the amount by which expenses of the fund exceed 0.66% of average daily net assets of the fund and expenses of Class NAV shares exceed 0.66% of average daily net assets attributable to the class. For purposes of these agreements, "expenses of the fund" means all fund expenses, excluding (a) taxes, (b) brokerage commissions, (c) interest expense, (d) litigation and indemnification expenses and other extraordinary expenses not incurred in the ordinary course of the fund's business, (e) class-specific expenses, (f) acquired fund fees and expenses paid indirectly, (g) borrowing costs, (h) prime brokerage fees, and (i) short dividend expense; and "expenses of Class NAV shares" means all expenses of the fund (as defined above) attributable to the class plus class-specific expenses. These agreements expire on December 31, 2019, unless renewed by mutual agreement of the fund and the advisor based upon a determination that this is appropriate under the circumstances at that time. The advisor also contractually agrees to waive a portion of its management fee and/or reimburse expenses for the fund and certain other John Hancock funds according to an asset level breakpoint schedule that is based on the aggregate net assets of all the funds participating in the waiver or reimbursement.

            The advisor contractually agrees to waive its management fee so that the amount retained by the advisor after payment of subadvisory fees does not exceed 0.45% of the fund's average daily net assets. The advisor also contractually agrees to reduce its management fee or, if necessary, make payment to the fund in an amount equal to the amount by which expenses of the fund exceed 0.79% of average daily net assets of the fund. For purposes of this agreement, "expenses of the fund" means all fund expenses, excluding (a) taxes, (b) brokerage commissions, (c) interest expense, (d) litigation and indemnification expenses and other extraordinary expenses not incurred in the ordinary course of the Fund's business, (e) class specific expenses, (f) underlying fund expenses (acquired fund fees), (g) borrowing costs, (h) prime brokerage fees, and (i) short dividend expense. The advisor also contractually agrees to reduce its management fee or, if necessary, make payment to the fund in an amount equal to the amount by which expenses of Class I shares exceed 0.90% of average daily net assets attributable to Class I shares. For purposes of this agreement, "expenses of Class I shares" means all expenses of the fund (as defined above) plus class-specific expenses. These agreements expire on December 31, 2019, unless renewed by mutual agreement of the fund and the advisor based upon a determination that this is appropriate under the circumstances at that time. The advisor also contractually agrees to waive a portion of its management fee and/or reimburse expenses for the fund and certain other John Hancock funds according to an asset level breakpoint schedule that is based on the aggregate net assets of all the funds participating in the waiver or reimbursement. This waiver is allocated proportionally among the participating funds. During its most recent fiscal year, the fund's reimbursement amounted to 0.01% of the fund's average daily net assets. This agreement expires on June 30, 2020, unless renewed by mutual agreement of the fund and the advisor based upon a determination that this is appropriate under the circumstances at that time.

            The advisor contractually agrees to reduce its management fee or, if necessary, make payment to the applicable class in an amount equal to the amount by which expenses of Class A and Class C shares, as applicable, exceed 1.14% and 1.89%, respectively, of average daily net assets attributable, to the applicable class. For purposes of this agreement, "expenses of Class A and Class C shares" means all class expenses (including fund expenses attributable, to the class), excluding (a) taxes; (b) portfolio brokerage commissions; (c) interest; (d) litigation and indemnification expenses and other extraordinary expenses not incurred in the ordinary course of the fund's business; (e) acquired fund fees and expenses paid indirectly; and (f) short dividend expense. The agreement expires on December 31, 2019, unless renewed by mutual agreement of the fund and the advisor based upon a determination that this is appropriate under the circumstances at that time. The advisor also contractually agrees to waive a portion of its management fee and/or reimburse expenses for the fund and certain other John Hancock funds according to an asset level breakpoint schedule that is based on the aggregate net assets of all the funds participating in the waiver or reimbursement. This waiver is allocated proportionally among the participating funds. During its most recent fiscal year, the fund's reimbursement amounted to 0.01% of the fund's average daily net assets. This agreement expires on June 30, 2020, unless renewed by mutual agreement of the fund and the advisor based upon a determination that this is appropriate under the circumstances at that time.

            The advisor contractually agrees to reduce its management fee or, if necessary, make payments to the fund, in an amount equal to the amount by which other expenses of the fund exceed 0.04% of average daily net assets of the fund. For purposes of this agreement, "Other expenses of the fund" means all fund expenses, excluding (a) taxes; (b) brokerage commissions; (c) interest expense; (d) litigation and indemnification expenses and other extraordinary expenses not incurred in the ordinary course of the fund's business; (e) advisory fees; (f) class-specific expenses; (g) underlying fund expenses (acquired fund fees); and (h) short dividend expense. The advisor also contractually agrees to reduce its management fee by 0.05% of the fund's average daily net assets up to $5 billion, and by 0.025% on average daily net assets of the fund over $5 billion. These agreements expire on December 31, 2019, unless renewed by mutual agreement of the fund and the advisor based upon a determination that this is appropriate under the circumstances at that time.

            The advisor contractually agrees to reduce its management fee or, if necessary, make payment to the fund in an amount equal to the amount by which certain expenses, including acquired fund fees, exceed 0.35% of the fund's average daily net assets. The advisor also contractually agrees to waive and/or reimburse all class-specific expenses for Class R6 shares to the extent they exceed 0.00% of average daily net assets attributable to the class. These agreements expire on December 31, 2019, unless renewed by mutual agreement of the fund and the advisor based upon a determination that this is appropriate under the circumstances at that time.

These agreements expire on December 31, 2019, unless renewed by mutual agreement of the fund and the advisor based upon a determination that this is appropriate under the circumstances at that time.

            The advisor contractually agrees to reduce its management fee or, if necessary, make payment to the fund in an amount equal to the amount by which certain expenses, including acquired fund fees, exceed 0.58% of the fund's average daily net assets. The advisor also contractually agrees to waive and/or reimburse all class-specific expenses for Class R6 shares to the extent they exceed 0.00% of average daily net assets attributable to the class. These agreements expire on December 31, 2019, unless renewed by mutual agreement of the fund and the advisor based upon a determination that this is appropriate under the circumstances at that time.

            The advisor contractually agrees to waive a portion of its management fee and/or reimburse expenses for the fund and certain other John Hancock funds according to an asset level breakpoint schedule that is based on the aggregate net assets of all the funds participating in the waiver or reimbursement. This waiver is allocated proportionally among the participating funds. During its most recent fiscal year, the fund's reimbursement amounted to 0.01% of the fund's average daily net assets. This agreement expires on June 30, 2020, unless renewed by mutual agreement of the fund and the advisor based upon a determination that this is appropriate under the circumstances at that time.
