¹	"Other expenses" have been restated from fiscal year amounts to reflect current fees and expenses.

²	"Acquired fund fees and expenses" are based on indirect net expenses associated with the fund's investments in underlying investment companies.

³	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."

⁴

The advisor has contractually agreed to waive and/or reimburse all class-specific expenses for Class A shares of the fund to the extent they exceed 0.41% of average annual net assets (on an annualized basis) attributable to Class A shares (the class expense waiver). The class expense waiver expires on April 30, 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.

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 in the fund for the time periods indicated assuming you redeem all of your shares at the end of those periods. For Class B and Class C shares, the expense examples may differ if shares are sold or kept at the end of the period. The example assumes a 5% average annual return. The example assumes 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:

3 years	887	921	621	624	624
5 years	1,170	1,268	1,068	1,073	1,073
10 years	1,977	2,128	2,128	2,317	2,317

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 22% of the average value of its portfolio.

Principal investment strategies

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.

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% in either direction. Thus, based on its target percentage allocation of approximately 20% of assets in equity underlying funds and 80% in fixed-income underlying funds, the fund may have an equity/fixed-income underlying fund allocation ranging between 10%/90% and 30%/70%. Although variations beyond the 10% range are generally not permitted, the subadvisors may determine, in light of market or economic conditions, that the normal percentage limitations should be exceeded to protect the fund or to achieve its goal.

The fund may invest in various underlying funds that, as a group, hold a wide range of equity-type securities. These include small-, mid-, and large-capitalization stocks; domestic and foreign securities (including emerging-market securities); and sector holdings. Each of these 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 options on securities and futures contracts. Certain of the underlying funds in which the fund invests 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.

The fund may invest in affiliated and nonaffiliated investment companies. In addition to investing in exchange-traded funds (ETFs), the fund may also invest in U.S. government securities and derivatives, such as credit default swaps and 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. The fund may also directly invest in exchange-traded notes (ETNs). The fund is also authorized to use various other investment strategies such as investing directly in fixed-income and equity securities, closed-end funds, and partnerships, and short-selling securities.

Principal risks

An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any other government agency. The fund's shares will go up and down in price, meaning that you could lose money by investing in the fund. Many factors influence a mutual fund's performance.

Instability in the financial markets has led many governments, including the U.S. government, to take a number of unprecedented actions designed to support certain financial institutions and segments of the financial markets that have experienced extreme volatility and, in some cases, a lack of liquidity. Federal, state, and other governments, and their regulatory agencies or self-regulatory organizations, may take actions that affect the regulation of the instruments in which the fund invests, or the issuers of such instruments, in ways that are unforeseeable. Legislation or regulation may also change the way in which the fund itself is regulated. Such legislation or regulation could limit or preclude the fund's ability to achieve its investment objective. In addition, political events within the United States and abroad, including the U.S. government's ongoing difficulty agreeing on a long-term budget and deficit reduction plan and uncertainty surrounding sovereign debt of European Union members, could negatively impact financial markets and the fund's performance. Further, certain municipalities of the United States and its territories are financially strained and may face the possibility of default on their debt obligations, which could directly or indirectly detract from the fund's performance.

Governments or their agencies may also acquire distressed assets from financial institutions and acquire ownership interests in those institutions. The implications of government ownership and disposition of these assets are unclear, and such a program may have positive or negative effects on the liquidity, valuation, and performance of the fund's portfolio holdings. Furthermore, volatile financial markets can expose the fund to greater market and liquidity risk and potential difficulty in valuing portfolio instruments held by the fund.

Because this fund has a greater exposure to underlying funds that invest primarily in fixed-income securities than John Hancock 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 Lifestyle Portfolios. In addition to fixed-income 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 33 of the prospectus.

Principal risks of investing in the fund of funds

Active management risk. A subadvisor's investment strategy may fail to produce the intended result.

Commodity risk. The market price of commodity investments may be volatile due to fluctuating demand, supply disruption, speculation, and other factors.

Credit and counterparty risk. The counterparty to an over-the-counter derivatives contract or a borrower of a fund's securities may be unable or unwilling to make timely principal, interest, or settlement 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 the fund and/or its service providers to suffer data corruption or lose operational functionality.

Exchange-traded funds risk. Owning an ETF generally reflects the risks of owning the underlying securities it is designed to track. An ETF has its own fees and expenses, which are indirectly borne by the fund.

Exchange-traded notes risk. Similar to ETFs, owning an ETN generally reflects the risks of owning the assets that compose the underlying market benchmark or strategy that the ETN is designed to reflect. ETNs also are subject to issuer and fixed-income risks.

Fund of funds risk. The fund is subject to the performance and expenses of the underlying funds in which it invests.

Hedging, derivatives, and other strategic transactions risk. Hedging, derivatives, and other strategic transactions may increase the volatility of a fund and, if the transaction is not successful, could result in a significant loss to a fund. The use of derivative instruments could produce disproportionate gains or losses, more than the principal amount invested. Investing in derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments and, in a down market, derivative instruments could become harder to value or sell at a fair price. The following is a list of certain derivatives and other strategic transactions that the fund intends to utilize and the main risks associated with each of them:

Credit default swaps. Counterparty risk, liquidity risk (i.e., the inability to enter into closing transactions), interest-rate risk, risk of default of the underlying reference obligation, and risk of disproportionate loss are the principal risks of engaging in transactions involving credit default swaps.

Foreign currency forward contracts. Counterparty risk, liquidity risk (i.e., the inability to enter into closing transactions), foreign currency risk, and risk of disproportionate loss are the principal risks of engaging in transactions involving foreign currency forward contracts.

Futures contracts. Counterparty risk, liquidity risk (i.e., the inability to enter into closing transactions), and risk of disproportionate loss are the principal risks of engaging in transactions involving futures contracts.

Interest-rate swaps. Counterparty risk, liquidity risk (i.e., the inability to enter into closing transactions), interest-rate risk, and risk of disproportionate loss are the principal risks of engaging in transactions involving interest-rate swaps.

Options. Counterparty risk, liquidity risk (i.e., the inability to enter into closing transactions), and risk of disproportionate loss are the principal risks of engaging in transactions involving options. Counterparty risk does not apply to exchange-traded options.

Investment company securities risk. The fund bears its own expenses and indirectly bears its proportionate share of expenses of the underlying funds in which it invests.

Short sales risk. Short sales involve costs and risk. The 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.

Principal risks of investing in the underlying funds

Fixed-income securities risk. Fixed-income securities are affected by changes in interest rates and credit quality. A rise in interest rates typically causes bond prices to fall. The longer the average maturity or average duration of the bonds held by a fund, the more sensitive the fund is likely to be to interest-rate changes. There is the possibility that the issuer of the security will not repay all or a portion of the principal borrowed and will not make all interest payments.

Active management risk. A fund's investment strategy may fail to produce the intended result.

Commodity risk. The market price of commodity investments may be volatile due to fluctuating demand, supply disruption, speculation, and other factors.

Convertible securities risk. The market values of convertible securities tend to decline as interest rates increase and, conversely, to increase as interest rates decline. In addition, as the market price of the underlying common stock declines below the conversion price, the price of the convertible security tends to be increasingly influenced by the yield of the convertible security.

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 a fund's securities may be unable or unwilling to make timely principal, interest, or settlement 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. Funds that invest in fixed-income securities are subject to varying degrees of risk that the issuers of the securities will have their credit rating downgraded or will default, potentially reducing a fund's share price and income level.

Currency risk. Fluctuations in exchange rates may adversely affect the U.S. dollar value of a fund's investments. Currency risk includes the risk that currencies in which a fund's investments are traded, or currencies in which a fund has taken an active position, will decline in value relative to the U.S. dollar.

John Hancock Lifestyle Conservative Portfolio

Economic and market events risk. Events in the financial markets have resulted, and may continue to result, in an unusually high degree of volatility in the financial markets, both domestic and foreign. In addition, relatively high market volatility and reduced liquidity in credit and fixed-income markets may adversely affect issuers worldwide. The conclusion of the U.S. Federal Reserve's quantitative easing stimulus program and/or increases in the level of short-term interest rates could cause fixed-income markets to experience continuing high volatility, which could negatively impact the fund's performance. Banks and financial services companies could suffer losses if interest rates were to rise or economic conditions deteriorate.

Emerging-market risk. The risks of investing in foreign securities are greater for investments in emerging markets. Emerging-market countries may experience higher inflation, interest rates, and unemployment, as well as greater social, economic, regulatory, and political uncertainties than more developed countries.

Equity securities risk. The value of a company's equity securities is subject to changes in the company's financial condition and overall market and economic conditions. The securities of growth companies are subject to greater price fluctuations than other types of stocks because their market prices tend to place greater emphasis on future earnings expectations. The securities of value companies are subject to the risk that the companies may not overcome adverse business developments or other factors causing their securities to be underpriced or that the market may never come to recognize their fundamental value.

Foreign securities risk. As compared with U.S. corporate and government issuers, there may be less publicly available information relating to foreign corporate and government issuers. Foreign securities may be subject to foreign taxes. The value of foreign securities is subject to currency fluctuations and adverse political and economic developments. Investments in emerging-market countries are subject to greater levels of foreign investment risk.

Hedging, derivatives, and other strategic transactions risk. Hedging, derivatives, and other strategic transactions may increase the volatility of a fund and, if the transaction is not successful, could result in a significant loss to a fund. The use of derivative instruments could produce disproportionate gains or losses, more than the principal amount invested. Investing in derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments and, in a down market, derivative instruments could become harder to value or sell at a fair price. The following is a list of certain derivatives and other strategic transactions that a fund intends to utilize and the main risks associated with each of them:

Industry or sector risk. Because a 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.

Initial public offerings risk. IPO shares may have a magnified impact on fund performance and are frequently volatile in price. They can be held for a short period of time, causing an increase in portfolio turnover.

Issuer risk. An issuer of a security may perform poorly and, therefore, the value of its stocks and bonds may decline. An issuer of securities held by a fund could default or have its credit rating downgraded.

Large company risk. Large-capitalization stocks as a group could fall out of favor with the market, causing a fund to underperform investments that focus on small- or mid-capitalization stocks. Larger, more established companies may be slow to respond to challenges and may grow more slowly than smaller companies. For purposes of a fund's investment policies, the market capitalization of a company is based on its market capitalization at the time the fund purchases the company's securities. Market capitalizations of companies change over time.

Liquidity risk. Exposure exists when reduced trading volume, a relative lack of market makers, or legal restrictions impair the ability to sell particular securities or close derivative positions at an advantageous price. Liquidity risk may result from the lack of an active market, the reduced number of traditional market participants, or the reduced capacity of traditional market participants to make a market in fixed-income securities. In addition, liquidity risk may be magnified in a rising interest rate environment in which investor redemptions from fixed-income mutual funds may be higher than normal; the selling of fixed-income securities to satisfy fund shareholder redemptions may result in an increased supply of such securities during periods of reduced investor demand due to a lack of buyers, thereby impairing the fund's ability to sell such securities.

Lower-rated fixed-income securities risk and high-yield securities risk. Lower-rated fixed-income securities and high-yield fixed-income securities (commonly known as junk bonds) are subject to greater credit quality risk and risk of default than higher-rated fixed-income securities. These securities may be considered speculative and the value of these securities can be more volatile due to increased sensitivity to adverse issuer, political, regulatory, market, or economic developments and can be difficult to resell.

Medium and smaller company risk. The prices of medium and smaller company stocks can change more frequently and dramatically than those of large company stocks. Market capitalizations of companies change over time.

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

Non-diversified risk. Overall risk can be reduced by investing in securities from a diversified pool of issuers and is increased by investing in securities of a small number of issuers. Investments in a non-diversified fund may magnify a fund's losses from adverse events affecting a particular issuer.

Past performance

The following performance information in the bar chart and table below 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. However, past performance (before and after taxes) does not indicate future results. All figures assume dividend reinvestment.

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.
