More information about these and other discounts is available from your financial professional and beginning on page 26 of the prospectus under “Sales charge reductions and waivers” or page 108 of the fund’s Statement of Additional Information under “Sales Charges on Class A and Class C Shares.” 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. 100000 Shareholder fees (%) (fees paid directly from your investment) 0.0400 0 0 0 0 0 0 0.0075 0.0100 0 0 0 0 0 20 20 0 0 0 0 0 Annual fund operating expenses (%) (expenses that you pay each year as a percentage of the value of your investment) 0.0035 0.0035 0.0035 0.0035 0.0035 0.0035 0.0035 0.0030 0.0100 0.0000 0.0025 0.0025 0.0000 0.0000 0.0000 0.0000 0.0000 0.0025 0.0010 0.0005 0.0000 0.0017 0.0017 0.0017 0.0007 0.0007 0.0007 0.0007 0.0017 0.0017 0.0017 0.0032 0.0017 0.0012 0.0007 0.0082 0.0152 0.0052 0.0092 0.0077 0.0047 0.0042 0.0000 0.0000 0.0000 0.0000 -0.0010 0.0000 0.0000 0.0082 0.0152 0.0052 0.0092 0.0067 0.0047 0.0042 September 30, 2027 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, 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: Shares Sold SharesNot Sold 480 255 53 94 68 48 43 155 651 480 167 293 236 151 135 480 837 829 291 509 418 263 235 829 1373 1624 653 1131 945 591 530 1624 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 55% of the average value of its portfolio. 0.55 Principal investment strategies Under normal market conditions, the fund invests at least 80% of its assets (plus borrowings for investment purposes) in the following types of fixed income 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, corporate debt, convertible debt, interest-paying preferred securities, mortgage and asset-backed securities and loans that may be rated investment-grade or below investment grade quality or are unrated.The fund may also invest in preferred stock. Although the fund may invest up to 10% of its total assets in securities rated as low as D (in default) by S&P Global Ratings (S&P), Moody’s Investors Service, Inc. (Moody’s), Fitch Ratings, Inc. (Fitch Ratings), or comparable rating by any nationally recognized statistical rating organization (NRSRO), or their unrated equivalents, it generally intends to keep its average credit quality in the investment-grade range (AAA to BBB). The fund’s investment policies are based on credit ratings at the time of purchase. There is no limit on the fund’s average maturity. The manager allocates assets among the types of securities described above based on analysis of economic factors such as projected international interest-rate movements, industry cycles, and political trends. The manager may invest up to 100% of the fund’s assets in any one sector. In making investment decisions, the manager looks at relative yield, credit quality, structure, industry distribution, and risk/reward ratios, among other factors.The manager considers environmental, social, and/or governance (ESG) factors, alongside other relevant factors, as part of its investment process. ESG factors may include, but are not limited to, matters regarding board diversity, climate change policies, and supply chain and human rights policies. The ESG characteristics utilized in the fund’s investment process may change over time and one or more characteristics may not be relevant with respect to all issuers that are eligible fund investments. Because ESG factors are considered alongside other relevant factors, the manager may determine that an investment is appropriate notwithstanding its relative ESG characteristics. The fund may use certain higher-risk investments, including restricted or illiquid securities and derivatives. Derivatives may be used to reduce risk, obtain efficient market exposure, and/or enhance investment returns, and may include futures contracts on securities, indexes, and foreign currency; options on futures contracts, securities, indexes, and foreign currency; interest-rate, foreign currency, and credit default swaps; and foreign currency forward contracts. The fund may invest up to 10% of its net assets in domestic or foreign common stocks. The fund may trade securities actively. Under normal market conditions, the fund invests at least 80% of its assets (plus borrowings for investment purposes) in the following types of fixed income 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, corporate debt, convertible debt, interest-paying preferred securities, mortgage and asset-backed securities and loans that may be rated investment-grade or below investment grade quality or are unrated. The manager allocates assets among the types of securities described above based on analysis of economic factors such as projected international interest-rate movements, industry cycles, and political trends. The manager may invest up to 100% of the fund’s assets in any one sector. In making investment decisions, the manager looks at relative yield, credit quality, structure, industry distribution, and risk/reward ratios, among other factors. 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. Changing distribution levels risk. The fund may cease or reduce the level of its distribution if income or dividends paid from its investments declines. 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. Defaulted debt risk. 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. 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. Equity securities risk. The price of equity securities may decline due to changes in a company’s financial condition or overall market conditions. ESG integration risk. The manager considers ESG factors that it deems relevant or additive, along with other material factors and analysis, when managing the fund. ESG factors may include, but are not limited to, matters regarding board diversity, climate change policies, and supply chain and human rights policies. The manager may consider these ESG factors on all or a meaningful portion of the fund’s investments. Integration of ESG factors into the fund’s investment process does not preclude the fund from including companies with low ESG characteristics or excluding companies with high ESG characteristics in the fund's investments. Incorporating ESG criteria and making investment decisions based on certain ESG characteristics, as determined by the manager, carries the risk that the fund may perform differently, including underperforming, funds that do not utilize ESG criteria, or funds that utilize different ESG criteria. 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, including foreign government 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 the fund intends to utilize include: credit default swaps, foreign currency forward contracts, foreign currency swaps, futures contracts, interest-rate swaps, options on futures, 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. High portfolio turnover risk. Trading securities actively and frequently can increase transaction costs (thus lowering performance) and taxable distributions. Large shareholder risk. A significant portion of a fund’s shares may be owned by one or more large shareholders, including investment vehicles and institutional investors. Transactions by these large shareholders may be disruptive to the management of the fund. For example, the fund may experience large redemptions and could be required to sell securities at a time when it may not otherwise desire to do so. Such transactions may increase the fund’s brokerage and/or other transaction costs, which could adversely impact fund performance. In addition, sizeable redemptions could cause the fund’s total expenses to increase. Large redemptions could also require the fund to make taxable distributions to shareholders, which may be borne disproportionately by non-redeeming shareholders. Illiquid and restricted securities risk. 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. Liquidity risk. 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. Loan participations risk. 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. 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. Factors that impact the value of these securities include interest rate changes, the reliability of available information, credit quality or enhancement, and market perception. Operational and 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. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes. Preferred stock risk. 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. 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. U.S. government agency obligations risk. The fund invests in obligations issued by agencies and instrumentalities of the U.S. government. U.S. government-sponsored entities such as Federal National Mortgage Association (Fannie Mae), Federal Home Loan Mortgage Corporation (Freddie Mac) and the Federal Home Loan Banks, although chartered or sponsored by Congress, are not funded by congressional appropriations and the debt securities that they issue are neither guaranteed nor issued by the U.S. government. Such debt securities are subject to the risk of default on the payment of interest and/or principal, similar to the debt securities of private issuers. The maximum potential liability of the issuers of some U.S. government obligations may greatly exceed their current resources, including any legal right to support from the U.S. government. Although the U.S. government has provided financial support to Fannie Mae and Freddie Mac in the past, there can be no assurance that it will support these or other government-sponsored entities in the future.
