1 "Service plan fee" has been restated to reflect maximum allowable fees.

2 "Other expenses" have been restated from fiscal year amounts to reflect current fees and expenses.

3 "Acquired fund fees and expenses" are based on indirect net expenses associated with the fund's investments in underlying investment companies.

4 The "Total annual fund operating expenses" shown may not correlate to the fund's ratios of expenses to average net assets shown in the "Financial highlights" section of the fund's prospectus, which does not include "Acquired fund fees and expenses."

5 The advisor contractually agrees to reduce its management fee or, if necessary, make payment to Class R1, Class R2, Class R4, and Class R6 shares, as applicable, in an amount equal to the amount by which expenses of the class exceed 0.75%, 0.50%, 0.25%, and 0.00%, respectively, of average annual net assets (on an annualized basis) attributable to the class. For purposes of this agreement, "expenses of the share class" means all expenses attributable to the class, excluding fund level expenses such as (a) advisory fees, (b) acquired fund fees, (c) taxes, (d) brokerage commissions, (e) interest expense, (f) litigation and indemnification expenses and other extraordinary expenses not incurred in the ordinary course of the fund's business and (g) short dividend expense. The advisor also contractually agrees to waive its advisory fees and/or reimburse certain expenses including acquired fund fees to reduce the total annual fund operating expenses of the fund by 0.20% of the fund's average net assets. These agreements expire on December 31, 2016, 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.

6 The distributor contractually agrees to waive 0.10% of Rule 12b-1 fees for Class R4 shares. This agreement expires on December 31, 2016, unless renewed by mutual agreement of the fund and the distributor based upon a determination that this is appropriate under the circumstances at that time.

Expense example

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:

Expenses ($)	R1	R2	R4	R6
1 year	123	98	73	47
3 years	429	351	294	193
5 years	756	623	533	352
10 years	1,684	1,402	1,220	815

Portfolio turnover

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 5% of the average value of its portfolio.

Principal investment strategies

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.

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 Retirement Choices at 2045 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 Retirement Choices 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.

GLIDE PATH CHART

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 for the broad asset classes of equity and fixed-income securities but may invest outside these target allocations to protect the fund or help it achieve its objective. The managers may change the target allocation without shareholder approval if they believe such change would benefit the fund and its shareholders. There is no guarantee that the 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.

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.

The fund may invest in underlying funds that invest in a broad range of equity and fixed-income 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.

The fund may invest in various actively and passively 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. 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 actively and passively managed underlying funds focus their investment strategy on fixed-income securities, which may include investment-grade and below-

John Hancock Retirement Choices at 2045 Portfolio

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.

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.

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.

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.

Principal risks

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.

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.

Because this fund has a greater exposure to underlying funds that invest primarily in equity securities than John Hancock Retirement Choices 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. Before investing, be sure to read the additional descriptions of these risks beginning on page 62 of the prospectus.

Principal risks of investing in the fund of funds

Credit and counterparty risk. 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.

Cybersecurity risk. 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.

Economic and market events risk. 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.

Exchange-traded funds risk. An ETF generally reflects the risks of the underlying securities it is designed to track. A fund bears ETF fees and expenses indirectly.

Exchange-traded notes risk. 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.

Fund of funds risk. 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.

Hedging, derivatives, and other strategic transactions risk. 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). 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.

Investment company securities risk. A fund bears underlying fund fees and expenses indirectly.

Lifecycle risk. 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.

Target allocation risk. Relatively large redemptions from or investments in an underlying fund due to reallocation or rebalancing of portfolio assets could affect the performance of the underlying fund and the fund.

Principal risks of investing in the underlying funds

Equity securities risk. 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.

John Hancock Retirement Choices at 2045 Portfolio

Commodity risk. 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.

Convertible securities risk. 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.

Credit and counterparty risk. 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.

Fixed-income securities risk. 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.

Foreign securities risk. 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.

Hedging, derivatives, and other strategic transactions risk. 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). 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.

Initial public offerings risk. IPO share prices are frequently volatile and may significantly impact fund performance.

Liquidity risk. An impairment of a fund's ability to sell securities or close derivative positions at advantageous prices exposes the fund to liquidity risk. Liquidity risk may result from 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.

Lower-rated and high-yield fixed-income securities risk. 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.

Mortgage-backed and asset-backed securities risk. Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.

Non-diversified risk. 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.

Sector risk. 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.

Short sales risk. 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.

Small and mid-size company risk. Small and mid-size companies are generally less established and may be more volatile than larger companies. Small capitalization securities may underperform the market as a whole.

Past performance

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 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.

Russell 3000 Index/MSCI ACWI ex-US Index/Barclays U.S. Aggregate Bond Index 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, 2013 to November 30, 2014, the Custom Benchmark consisted of the following indices and approximate weightings: 57% Russell 3000 Index, 25% MSCI ACWI ex-US Index, and 18% 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, 2013.

A note on performance

Class 1 and Class R4 shares commenced operations on April 30, 2010, and May 1, 2012, respectively. Class R1, Class R2, and Class R6 shares commenced operations on September 4, 2012. Returns prior to the commencement date of Class R1, Class R2, and Class R6 shares are those of Class 1 shares that have been recalculated to apply the gross fees and expenses of Class R1, Class R2, and Class R6 shares, as applicable. Returns prior to the commencement date of Class R4 shares 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.

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.

Withdrawals from such tax-deferred arrangements may be subject to tax at a later date.

Payments to broker-dealers and other financial intermediaries

If you purchase the fund through a broker-dealer or other financial intermediary (such as a bank, registered investment advisor, financial planner, or retirement plan administrator), the fund and its related companies may pay the broker-dealer or other intermediary for the sale of fund shares and related services.
