Fees and expenses

This table describes the fees and expenses you may pay if you buy and hold shares of the fund. 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 $100,000 in the John Hancock family of funds. More information about these and other discounts is available from your financial representative and on pages 17 to 18 of the prospectus under "Sales charge reductions and waivers" or pages 119 to 122 of the fund's Statement of Additional Information under "Initial sales charge on Class A shares."

Total annual fund operating expenses after expense reimbursements	0.93	1.63	1.63

¹ The advisor has contractually agreed to waive a portion of its management fee and/or reimburse or pay operating expenses of the fund in order to reduce the total annual fund operating expenses for Class A, Class B, and Class C shares by 0.05% of the fund's average daily net assets. These fee waivers and/or reimbursements expire on September 30, 2015, 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:

Expenses ($)	Class A	Class B		Class C
Shares		Sold	Kept	Sold	Kept
1 year	491	666	166	266	166
3 years	695	825	525	525	525
5 years	915	1,108	908	908	908
10 years	1,549	1,797	1,797	1,983	1,983

Portfolio turnover

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 77% of the average value of its portfolio.

Principal investment strategies

Under normal market conditions, the fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in a diversified portfolio of bonds. These may include, but are not limited to, corporate bonds and debentures, as well as U.S. government and agency securities. Most of these securities are investment grade, although the fund may invest up to 25% of its net assets in debt securities rated, at the time of acquisition, below investment grade (i.e., junk bonds) as low as CC by Standard & Poor's Ratings Services (S&P) and Ca by Moody's Investors Service, Inc. (Moody's), or in unrated securities determined by the fund's investment advisor or subadvisor to be of comparable credit quality. The fund contemplates that at least 75% of the value of its net assets will be in investment-grade debt securities and cash and cash equivalents. There is no limit on the fund's average maturity.

In managing the fund's portfolio, the subadvisor concentrates on sector allocation, industry allocation, and security selection, deciding which types of bonds and industries to emphasize at a given time, and then which individual bonds to buy. When making sector and industry allocations, the subadvisor tries to anticipate shifts in the business cycle, using top-down analysis to determine which sectors and industries may benefit over the next 12 months.

In choosing individual securities, the subadvisor uses bottom-up research to find securities that appear comparatively undervalued. The subadvisor looks at bonds of all quality levels and maturities from many different issuers, potentially including foreign governments and corporations denominated in U.S. dollars or foreign currencies. The fund will not invest more than 10% of its total assets in securities denominated in foreign currencies. It is anticipated that under normal market conditions, the fund will not invest more than 25% of its total assets in U.S. dollar-denominated foreign securities (excluding U.S. dollar-denominated Canadian securities).

The fund intends to keep its exposure to interest-rate movements generally in line with those of its peers. The fund may invest in mortgage-related securities and derivatives, which include futures contracts on securities and indexes; options on futures contracts, securities, and indexes; interest-rate, foreign currency, and credit default 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's investments in U.S. government and agency securities may or may not be supported by the full faith and credit of the United States.

Under normal circumstances, the fund may not invest more than 10% of its assets in cash or cash equivalents (except cash segregated in relation to futures, forward, and options contracts).

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. 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.

The fund's main risk factors are listed below in alphabetical order. Before investing, be sure to read the additional descriptions of these risks beginning on page 6 of the prospectus.

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

Changing distribution levels risk. The distribution amounts paid by the fund generally depend on the amount of income and/or dividends paid by the fund's investments.

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.

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, reduced liquidity in credit and fixed-income markets may adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates were to rise or economic conditions deteriorate.

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 the 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.

Foreign securities risk. As compared to 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.

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, 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.

Foreign currency swaps. 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 swaps.

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.

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.

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.

Sector investing risk. Because the fund may focus on a single sector of the economy, its performance depends in large part on the performance of that sector. As a result, the value of your investment may fluctuate more widely than it would in a fund that is diversified across sectors.

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. Performance for the fund is updated daily, monthly, and quarterly, and may be obtained at our website, jhinvestments.com/FundPerformance, or by calling 800-225-5291, Monday–Thursday between 8:00 A.M. and 7:00 P.M., and on Friday, between 8:00 A.M. and 6:00 P.M., Eastern time.

Calendar year total returns. These do not include sales charges and would have been lower if they did. Calendar year total returns are shown only for Class A shares and would be different for other share classes.

Average annual total returns. Performance of a broad-based market index is included for comparison.  The average annual total returns shown below reflect the sales charges in effect during the periods shown. 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.

After-tax returns. These are shown only for Class A shares and would be different for other classes. They reflect the highest individual federal marginal income-tax rates in effect as of the date provided and do not reflect any state or local taxes. Your actual after-tax returns may be different.

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 intermediary for the sale of fund shares and related services.
