A message to shareholders

Dear fellow shareholder,

Stronger economic growth in the United States set the global standard in 2014, and it appears to be continuing to do so in 2015. The portfolio teams in our network are generally optimistic about continued relative strength in the United States, supported by rising employment, healthy consumer spending, and falling oil prices. Stocks at all-time highs remain vulnerable to a correction, but the long-term bull market appears intact. We believe a more selective approach continues to make sense in overseas markets, but opportunities abroad are growing and could reward investors should recoveries in certain markets begin in earnest.

While the U.S. equity market appears strong, this year will likely present greater challenges for bond investors. The U.S. Federal Reserve has signaled its intention to raise short-term interest rates in 2015, and that change may have an adverse effect on many fixed-income portfolios, particularly those that invest in less liquid asset classes. At John Hancock Investments, we are closely monitoring the liquidity of our fixed-income portfolios and communicating regularly with their portfolio managers about these matters. Now may also be a good time for you to discuss your fixed-income strategy with your financial advisor to determine if that portion of your portfolio continues to match your long-term goals.

A new look

I am pleased to introduce you to our redesigned shareholder reports. As part of an effort to elevate the educational substance in our communications, we undertook an initiative to make our reports more engaging and easier to navigate. Included in the changes are a performance snapshot that shows your fund's performance against that of its benchmark, and a Q&A with your fund's lead portfolio manager. We hope these enhancements give you better insight into your fund's activity and performance.

On behalf of everyone at John Hancock Investments, I'd like to take this opportunity to thank you for the continued trust you've placed in us.

Sincerely,

INVESTMENT OBJECTIVE


The fund seeks to provide a high level of current income consistent with preservation of capital. The fund's secondary objective is to provide growth of capital to the extent consistent with its primary objective.

AVERAGE ANNUAL TOTAL RETURNS AS OF 1/31/15 (%)

The fund's performance is compared to the fund's benchmark, the Bank of America Merrill Lynch Hybrid Preferred Securities Index. Historically, the fund's performance has also been compared to the Barclays U.S. Aggregate Bond Index. The use of the Barclays U.S. Aggregate Bond Index as a benchmark will be discontinued due to the minimal overlap in holdings between the fund and index and this comparison will no longer be included after the next annual report.

The Bank of America Merrill Lynch Hybrid Preferred Securities Index is a subset of the Bank of America Merrill Lynch Fixed Rate Preferred Securities Index including all subordinated securities with a payment deferral feature. The Bank of America Merrill Lynch Fixed Rate Preferred Securities Index tracks the performance of fixed rate U.S. dollar denominated preferred securities issued in the U.S. domestic market. Qualifying securities must have an investment grade rating and must have an investment grade rated country of risk.

The Barclays U.S. Aggregate Bond Index is an unmanaged index of dollar-denominated and nonconvertible investment-grade debt issues.

It is not possible to invest directly in an index.

The current annualized distribution rates are the latest monthly distribution rate as an annualized percentage of net asset value or closing market price and are 7.61% at net asset value and 8.06% at closing market price on 1-31-15.

The fund's monthly distributions may be from net investment income, capital gains, or return of capital. Of the distributions paid through 1-31-15, it is currently estimated that the fund's distributions consist of net investment income. These amounts are estimates, and the actual amounts and sources of distributions for tax reporting purposes may change upon final determination of tax characteristics and may be subject to changes based on tax regulations. John Hancock Investments will send shareholders an IRS Form 1099-DIV for the calendar year that will explain how to report these distributions for federal income tax purposes. The total returns for the fund assume all distributions are reinvested.

The performance data contained within this material represents past performance, which does not guarantee future results.

PERFORMANCE HIGHLIGHTS OVER THE LAST SIX MONTHS


Utilities holdings performed well

The fund benefited from holdings in the utilities sector, the source of many of its best performers.

Senior housing holdings contributed

Real estate investment trusts issued by senior housing companies also aided the fund's performance.

Callable securities detracted

Slack demand for securities that were redeemable by their issuers over the near term hurt results as their potential price appreciation was limited.

A note about risks

As is the case with all closed-end funds, shares of this fund may trade at a discount to the fund's net asset value (NAV). An investment in the fund is subject to investment and market risks, including the possible loss of the entire principal invested. There is no guarantee prior distribution levels will be maintained and distributions may include a substantial return of capital, which may increase the potential tax gain or reduce the potential tax loss of a subsequent sale of shares of the fund. Fixed-income investments are subject to interest-rate risk; their value will normally decline as interest rates rise or if a creditor, grantor, or counterparty is unable or unwilling to make principal, interest, or settlement payments. An issuer of securities held by the fund may default, have its credit rating downgraded, or otherwise perform poorly, which may affect fund performance.Certain market conditions, including reduced trading volume, heightened volatility, or rising interest rates,may impair liquidity, the ability of the fund to sell securities or close derivative positions at advantageous prices.The fund's use of leverage creates additional risks, including greater volatility of the fund's NAV, market price, and returns.There is no assurance that the fund's leverage strategy will be successful. Focusing on a particular industry or sector may increase the fund's volatility and make it more susceptible to market, economic, and regulatory risks as well as other factors affecting those industries or sectors.

The fund normally will invest at least 25% of its total assets in the industries composing the utilities sector, which includes telecommunications companies, measured at the time of purchase. When the fund's investments focus on one or more sectors of the economy, they are far less diversified than the broad securities markets. This means that the fund may be more volatile than other funds, and the values of its investments may go up and down more rapidly. Because utility companies are capital intensive, they can be hurt by higher interest rates, which would increase the companies' interest burden. They can also be affected by costs in connection with capital construction programs, costs associated with environmental and other regulations, and the effects of economic declines, surplus capacity, and increased competition. In addition, the fund may invest in financial services companies, which can be hurt by economic declines, changes in interest rates and regulatory and market impacts. The fund's investments in securities of foreign issuers involve special risks such as political, economic, and currency risks and differences in accounting standards and financial reporting.

Discussion of fund performance

An interview with Portfolio Manager Gregory K. Phelps, John Hancock Asset Management a division of Manulife Asset Management (US) LLC

 Gregory K. Phelps
Portfolio Manager
John Hancock Asset Management

Most preferred securities performed quite well during the six-month period ended January 31, 2015. What factors contributed to their success?

With heightened volatility in global financial markets, preferred securities benefited throughout much of the six-month period from strong demand for such securities, amid limited supply. Early in the period, many preferred securities were able to hold their ground, despite growing uncertainty about the strength of the global economy, violent flare-ups in the Middle East, and periodic concern that the U.S. Federal Reserve (Fed) might raise interest rates sooner than advertised. In the final three months of 2014, preferred securities performed well relative to common stocks, as declining long-term U.S. Treasury and European government bond yields helped further bolster demand for preferred securities and global investors searched for yield. Demand was also fueled by investors seeking a haven from equity market volatility amid the weakening global economic growth outlook and the collapse in oil and other commodity prices. This trend continued into January 2015. Continued volatility hit common stocks, as investors grappled with concerns about the impact of a stronger dollar and lower oil prices on corporate earnings growth. Meanwhile, U.S. Treasury bond yields slumped, with the 30-year yield hitting a record all-time low since the government began auctioning off its debt in 1977. Together, equity market volatility and low government bond yields continued to support demand for preferred securities. Throughout the period, the supply of preferreds remained constrained.

After turning in one of their strongest performance years ever in 2014, can preferred securities stage a repeat in 2015?

Although we think it's unlikely that preferred securities will produce the types of gains during the coming year that they enjoyed in 2014, we believe they have a lot working in their favor. We don't expect the Fed to raise interest rates before the latter part of 2015. We expect inflation will remain benign as well, in part due to slumping oil and other commodity prices.

While the U.S. economy seems to be on the path of continual healing, European economic growth is likely to remain meager. We'll have to wait and see whether the European Central Bank's (ECB)

"... we think it's unlikely that preferred securities will produce the types of gains during the coming year that they enjoyed in 2014... "
efforts to jumpstart the continent's economy are ultimately effective. However, we expect that the ECB's recent launch of quantitative easing will most likely depress interest rates there. If that proves to be the case, we would expect U.S. Treasury yields to remain low as global investors continue to seek U.S. income-producing investments as higher-yielding alternatives to European sovereign debt. Investors wary of putting more money into common stocks—which have experienced an uptick in volatility in recent months and whose valuations may be reflecting a best-case global economic scenario—may turn to preferreds.

What holdings contributed to performance?

The utilities sector was the source of many of the fund's best performers during the six-month period, with securities issued by PPL Capital Funding, Inc. (PPL) and Duke Energy Corp. among the leaders. Each generated impressive price gains, helped by strong demand for the securities from investors seeking higher-yielding securities from industries not highly correlated with the larger economic cycle. While investors' appetite for higher-yielding investments boosted demand, the comparative lack of supply of these issues also helped. Many utilities redeemed their outstanding preferred shares years ago, and those still outstanding benefited from relative scarcity as a result. We also saw good performance from real estate investment trusts. For example, Senior Housing Properties Trust and Ventas Realty LP benefited from better-than-expected demand for their properties. Holdings in Stanley Black & Decker, Inc. also bolstered the fund's results. The tool maker's

profits topped expectations, benefiting from growth in emerging markets, the slow recovery in the U.S. housing market (which was good for home improvements), and cost-cutting measures.

What hurt the fund's performance?

Holdings in the preferred securities of ING Groep NV and Morgan Stanley detracted. Investors shied away from these securities given that the preferreds were callable, which limited their potential for price appreciation.

Can you explain the fund's use of leverage?

As of January 31, 2015, the fund had $292.5 million outstanding under its committed facility agreement for investing purposes. The primary aim of this line is to support the fund's yield by investing in securities whose distribution rates exceed the fund's borrowing costs. The fund has entered into interest rate swaps, which are intended to help offset some of the increased costs of leverage the fund may experience if interest rates rise. Futures and swaps contracts achieved the desired exposure but had a negative effect on performance.

Where are you finding opportunities of late?

Although we took advantage of opportunities to purchase new names we felt were attractively valued, there weren't any major changes to the portfolio during the period. That said, a handful of higher-coupon holdings were redeemed by their issuers; we redeployed the proceeds from these calls in a few areas. For example, we added to some of the fund's utility preferred securities, such as PPL. We also added to the fund's positions in higher-coupon preferred securities issued by

JPMorgan Chase & Co. and Wells Fargo & Company when they, too, seemed undervalued. We liked the fact that we could invest the fund in the tax-advantaged preferreds of these stable, large U.S. financial institutions at comparatively attractive prices.

Notes to financial statements (unaudited)

Note 1 — Organization

John Hancock Preferred Income Fund (the fund) is a closed-end management investment company organized as a Massachusetts business trust and registered under the Investment Company Act of 1940, as amended (the 1940 Act).

Note 2 — Significant accounting policies

The financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (US GAAP), which require management to make certain estimates and assumptions as of the date of the financial statements. Actual results could differ from those estimates and those differences could be significant. The fund qualifies as an investment company under Topic 946 of Accounting Standards Codification of US GAAP.

Events or transactions occurring after the end of the fiscal period through the date that the financial statements were issued have been evaluated in the preparation of the financial statements. The following summarizes the significant accounting policies of the fund:

Security valuation. Investments are stated at value as of the close of regular trading on the New York Stock Exchange (NYSE), normally at 4:00 p.m., Eastern Time. In order to value the securities, the fund uses the following valuation techniques: Equity securities held by the fund are valued at the last sale price or official closing price on the exchange where the security was acquired or most likely will be sold. In the event there were no sales during the day or closing prices are not available, the securities are valued using the last available bid price. Debt obligations are valued based on the evaluated prices provided by an independent pricing vendor or from broker-dealers. Independent pricing vendors utilize matrix pricing which takes into account factors such as institutional-size trading in similar groups of securities, yield, quality, coupon rate, maturity, type of issue, trading characteristics and other market data, as well as broker supplied prices. Swaps are valued using evaluated prices obtained from an independent pricing vendor. Futures contracts are valued at settlement prices, which are the official closing prices published by the exchange on which they trade. Foreign securities and currencies are valued in U.S. dollars, based on foreign currency exchange rates supplied by an independent pricing vendor. Securities that trade only in the over-the-counter (OTC) market are valued using bid prices. Certain short-term securities with maturities of 60 days or less at the time of purchase are valued at amortized cost.

Other portfolio securities and assets, for which reliable market quotations are not readily available, are valued at fair value as determined in good faith by the fund's Pricing Committee following procedures established by the Board of Trustees. The frequency with which these fair valuation procedures are used cannot be predicted and fair value of securities may differ significantly from the value that would have been used had a ready market for such securities existed. Trading in foreign securities may be completed before the daily close of trading on the NYSE. Significant events at the issuer or market level may affect the values of securities between the time when the valuation of the securities is generally determined and the close of the NYSE. If a significant event occurs, these securities may be fair valued, as determined in good faith by the fund's Pricing Committee, following procedures established by the Board of Trustees. The fund uses fair value adjustment factors provided by an independent pricing vendor to value certain foreign securities in order to adjust for events that may occur between the close of foreign exchanges or markets and the close of the NYSE.

The fund uses a three-tier hierarchy to prioritize the pricing assumptions, referred to as inputs, used in valuation techniques to measure fair value. Level 1 includes securities valued using quoted prices in active markets for identical securities. Level 2 includes securities valued using other significant observable inputs. Observable inputs may include quoted prices for similar securities, interest rates, prepayment speeds and credit risk. Prices for securities valued using these inputs are received from independent pricing vendors and brokers and are based on an evaluation of the inputs described. Level 3 includes securities valued using significant unobservable inputs when market prices are not readily available or reliable, including the fund's own assumptions in determining the fair value of investments. Factors used in determining value may include market or issuer specific events or trends, changes in interest rates and credit quality. The inputs or methodology used for valuing securities are not necessarily an indication of the risks associated with investing in those securities. Changes in valuation techniques may result in transfers into or out of an assigned level within the disclosure hierarchy.

Repurchase agreements. The fund may enter into repurchase agreements. When the fund enters into a repurchase agreement, it receives collateral that is held in a segregated account by the fund's custodian. The collateral amount is marked-to-market and monitored on a daily basis to ensure that the collateral held is in an amount not less than the principal amount of the repurchase agreement plus any accrued interest. Collateral received by the fund for repurchase agreements is disclosed in the Fund's investments as part of the caption related to the repurchase agreement.

Repurchase agreements are typically governed by the terms and conditions of the Master Repurchase Agreement and/or Global Master Repurchase Agreement (collectively, MRA). Upon an event of default, the non-defaulting party may close out all transactions traded under the MRA and net amounts owed. Absent an event of default, the MRA does not result in an offset of the reported amounts of assets and liabilities in the Statement of assets and liabilities. In the event of a default by the counterparty, realization of the collateral proceeds could be delayed, during which time the collateral value may decline or the counterparty may have insufficient assets to pay back claims resulting from close-out of the transactions.

Security transactions and related investment income. Investment security transactions are accounted for on a trade date plus one basis for daily net asset value calculations. However, for financial reporting purposes, investment transactions are reported on trade date. Interest income is accrued as earned. Interest income includes coupon interest and amortization/accretion of premiums/discounts on debt securities. Debt obligations may be placed in a non-accrual status and related interest income may be reduced by stopping current accruals and writing off interest receivable when the collection of all or a portion of interest has become doubtful. Dividend income is recorded on the ex-date, except for dividends of foreign securities where the dividend may not be known until after the ex-date. In those cases, dividend income, net of withholding taxes, is recorded when the fund becomes aware of the dividends. Gains and losses on securities sold are determined on the basis of identified cost and may include proceeds from litigation.

Real estate investment trusts. The fund may invest in real estate investment trusts (REITs). Distributions from REITs may be recorded as income and subsequently characterized by the REIT at the end of the fiscal year as a reduction of cost of investments and/or as a realized gain. As a result, the fund will estimate the components of distributions from these securities. Such estimates are revised when the actual components of the distributions are known.

18


Overdrafts. Pursuant to the custodian agreement, the fund's custodian may, in its discretion, advance funds to the fund to make properly authorized payments. When such payments result in an overdraft, the fund is obligated to repay the custodian for any overdraft, including any costs or expenses associated with the overdraft. The custodian may have a lien, security interest or security entitlement in any fund property that is not otherwise segregated or pledged, to the maximum extent permitted by law, to the extent of any overdraft.

Expenses. Within the John Hancock group of funds complex, expenses that are directly attributable to an individual fund are allocated to such fund. Expenses that are not readily attributable to a specific fund are allocated among all funds in an equitable manner, taking into consideration, among other things, the nature and type of expense and the fund's relative net assets. Expense estimates are accrued in the period to which they relate and adjustments are made when actual amounts are known.

Federal income taxes. The fund intends to continue to qualify as a regulated investment company by complying with the applicable provisions of the Internal Revenue Code and will not be subject to federal income tax on taxable income that is distributed to shareholders. Therefore, no federal income tax provision is required.

Under the Regulated Investment Company Modernization Act of 2010, the fund is permitted to carry forward capital losses incurred in taxable years beginning after December 22, 2010 for an unlimited period. Any losses incurred during those taxable years will be required to be utilized prior to the losses incurred in pre-enactment taxable years. As a result of this ordering rule, pre-enactment capital loss carryforwards may be more likely to expire unused. Additionally, post-enactment capital losses that are carried forward will retain their character as either short-term or long-term capital losses rather than being considered all short-term as under previous law.

For federal income tax purposes, as of July 31, 2014, the fund has a capital loss carryforward of $74,822,686 available to offset future net realized capital gains. The following table details the capital loss carryforward available:

         
CAPITAL LOSS CARRYFORWARD EXPIRING AT JULY 31 NO EXPIRATION DATE
2017 2018 2019 SHORT TERM LONG TERM
$53,099,790 $11,734,215 $2,278,715 $7,709,966

As of July 31, 2014, the fund had no uncertain tax positions that would require financial statement recognition, derecognition or disclosure. The fund's federal tax returns are subject to examination by the Internal Revenue Service for a period of three years.

Distribution of income and gains. Distributions to shareholders from net investment income and net realized gains, if any, are recorded on the ex-date. The fund generally declares and pays dividends monthly and capital gain distributions, if any, annually.

Such distributions, on a tax basis, are determined in conformity with income tax regulations, which may differ from US GAAP.

Capital accounts within the financial statements are adjusted for permanent book-tax differences. These adjustments have no impact on net assets or the results of operations. Temporary book-tax differences, if any, will reverse in a subsequent period. Book-tax differences are primarily attributable to derivative transactions and REITs.

Statement of cash flows. Information on financial transactions that have been settled through the receipt and disbursement of cash is presented in the Statement of cash flows. The cash amount shown in the Statement of cash flows is the amount included in the fund's Statement of assets and liabilities and represents the cash on hand at the fund's custodian and does not include any short-term investments, cash segregated at the custodian for swap contracts or cash held at the broker for futures contracts.

Note 3 — Derivative instruments

The fund may invest in derivatives in order to meet its investment objectives. Derivatives include a variety of different instruments that may be traded in the over-the-counter market, on a regulated exchange or through a clearing facility. The risks in using derivatives vary depending upon the structure of the instruments, including the use of leverage, optionality, the

19


liquidity or lack of liquidity of the contract, the creditworthiness of the counterparty or clearing organization and the volatility of the position. Some derivatives involve risks that are potentially greater than the risks associated with investing directly in the referenced securities or other referenced underlying instrument. Specifically, the fund is exposed to the risk that the counterparty to an OTC derivatives contract will be unable or unwilling to make timely settlement payments or otherwise honor its obligations. OTC derivatives transactions typically can only be closed out with the other party to the transaction.

Swaps are typically traded through the OTC market. Derivative counterparty risk is managed through an ongoing evaluation of the creditworthiness of all potential counterparties and, if applicable, designated clearing organizations. The fund attempts to reduce its exposure to counterparty risk for derivatives traded in the OTC market, whenever possible, by entering into an International Swaps and Derivatives Association (ISDA) Master Agreement with each of its OTC counterparties. The ISDA gives each party to the agreement the right to terminate all transactions traded under the agreement if there is certain deterioration in the credit quality or contractual default of the other party, as defined in the ISDA. Upon an event of default or a termination of the ISDA, the non-defaulting party has the right to close out all transactions and to net amounts owed.

As defined by the ISDA, the fund may have collateral agreements with certain counterparties to mitigate counterparty risk on OTC derivatives. Subject to established minimum levels, collateral for OTC transactions is generally determined based on the net aggregate unrealized gain or loss on contracts with a particular counterparty. Collateral pledged to the fund is held in a segregated account by a third-party agent or held by the custodian bank for the benefit of the fund and can be in the form of cash or debt securities issued by the U.S. government or related agencies; collateral posted by the fund for OTC transactions is held in a segregated account at the fund's custodian and is noted in the accompanying Fund's investments, or if cash is posted, on the Statement of assets and liabilities. The fund's maximum risk of loss due to counterparty risk is equal to the asset value of outstanding contracts offset by collateral received.

For financial reporting purposes, the fund does not offset OTC derivative assets or liabilities that are subject to master netting arrangements, as defined by the ISDAs, in the Statement of assets and liabilities. In the event of default by the counterparty or a termination of the agreement, the ISDA allows an offset of amounts across the various transactions between the fund and the applicable counterparty.

Futures are traded on an exchange. Exchange-traded transactions generally present less counterparty risk to a fund than OTC transactions. The exchange stands between the fund and the broker to the contract and therefore, credit risk is generally limited to the failure of the exchange.

Margin requirements for exchange-traded derivatives are set by the broker or applicable clearinghouse. Margin for exchange-traded transactions are detailed in the Statement of assets and liabilities as Cash held at broker for futures contracts.

Futures. A futures contract is a contractual agreement to buy or sell a particular currency or financial instrument at a pre-determined price in the future. Risks related to the use of futures contracts include possible illiquidity of the futures markets, contract prices that can be highly volatile and imperfectly correlated to movements in the underlying financial instrument and potential losses in excess of the amounts recognized on the Statement of assets and liabilities. Use of long futures contracts subjects the fund to the risk of loss up to the notional value of the futures contracts. Use of short futures contracts subjects the fund to unlimited risk of loss.

Upon entering into a futures contract, the fund is required to deposit initial margin with the broker in the form of cash or securities. The amount of required margin is generally based on a percentage of the contract value; this amount is the initial margin for the trade. The margin deposit must then be maintained at the established level over the life of the contract. Futures margin receivable / payable is included on the Statement of assets and liabilities. Futures contracts are marked-to-market daily and an appropriate payable or receivable for the change in value (variation margin) and unrealized gain or loss is recorded by the fund. When the contract is closed, the fund records a realized gain or loss equal to the difference between the value of the contract at the time it was opened and the value at the time it was closed.

During the six months ended January 31, 2015, the fund used futures contracts to manage against anticipated interest rate changes. During the six months ended January 31, 2015, the fund held futures contracts with notional values ranging from

20


$79.8 million to $83.8 million, as measured at each quarter end. The following table summarizes the contracts held at January 31, 2015.

Notional basis refers to the contractual amount agreed upon at inception of open contracts; notional value represents the current value of the open contract.

Interest rate swaps. Interest rate swaps represent an agreement between the fund and a counterparty to exchange cash flows based on the difference between two interest rates applied to a notional amount. The payment flows are usually netted against each other, with the difference being paid by one party to the other. The fund settles accrued net interest receivable or payable under the swap contracts at specified, future intervals. Swap agreements are privately negotiated in the OTC market or may be executed on a registered commodities exchange (centrally cleared swaps). Swaps are marked-to-market daily and the change in value is recorded as unrealized appreciation/depreciation of swap contracts. A termination payment by the counterparty or the fund is recorded as realized gain or loss, as well as the net periodic payments received or paid by the fund. The value of the swap will typically impose collateral posting obligations on the party that is considered out-of-the-money on the swap.

Entering into swap agreements involves, to varying degrees, elements of credit, market and documentation risk that may amount to values that are in excess of the amounts recognized on the Statement of assets and liabilities. Such risks involve the possibility that there will be no liquid market for the swap, or that a counterparty may default on its obligation or delay payment under the swap terms. The counterparty may disagree or contest the terms of the swap. Market risks may also accompany the swap, including interest rate risk. The fund may also suffer losses if it is unable to terminate or assign outstanding swaps or reduce its exposure through offsetting transactions.

During the six months ended January 31, 2015, the fund used interest rate swaps to manage against anticipated interest rate changes. The following table summarizes the interest rate swap contracts held during the six months ended January 31, 2015 and as of January 31, 2015.

Note 4 — Guarantees and indemnifications

Under the fund's organizational documents, its Officers and Trustees are indemnified against certain liabilities arising out of the performance of their duties to the fund. Additionally, in the normal course of business, the fund enters into contracts with service providers that contain general indemnification clauses. The fund's maximum exposure under these arrangements is unknown, as this would involve future claims that may be made against the fund that have not yet occurred. The risk of material loss from such claims is considered remote.

Note 5 — Fees and transactions with affiliates

John Hancock Advisers, LLC (the Advisor) serves as investment advisor for the fund. The Advisor is an indirect, wholly owned subsidiary of Manulife Financial Corporation (MFC).

Management fee. The fund has an investment management agreement with the Advisor under which the fund pays a daily management fee to the Advisor, on an annual basis, equal to 0.75% of the fund's average daily managed assets including any assets attributable to the Committed Facility Agreement (see Note 7) (collectively, managed assets). The Advisor has a subadvisory agreement with John Hancock Asset Management a division of Manulife Asset Management (US) LLC, an indirectly owned subsidiary of MFC and an affiliate of the Advisor. The fund is not responsible for payment of the subadvisory fees.

Effective January 2, 2015, the Advisor has contractually agreed to waive a portion of its management fee and/or reimburse expenses for certain funds of the John Hancock complex, including the fund (the participating portfolios). The waiver equals, on an annualized basis, 0.01% of that portion of the aggregate net assets of all the participating portfolios that exceeds $75 billion but is less than or equal to $125 billion; 0.0125% of that portion of the aggregate net assets of all the participating portfolios that exceeds $125 billion but is less than or equal to $150 billion; 0.015% of that portion of the aggregate net assets of all the participating portfolios that exceeds $150 billion but is less than or equal to $175 billion; 0.0175% of that portion of the aggregate net assets of all the participating portfolios that exceeds $175 billion but is less than or equal to $200 billion; 0.02% of that portion of the aggregate net assets of all the participating portfolios that exceeds $200 billion but is less than or equal to $225 billion; and 0.0225% of that portion of the aggregate net assets of all the participating portfolios that exceeds $225 billion. The amount of the reimbursement is calculated daily and allocated among all the participating portfolios in proportion to the daily net assets of each fund. This arrangement may be amended or terminated at any time by the Advisor upon notice to the fund and with the approval of the Board of Trustees.

Prior to January 2, 2015, the Advisor had contractually agreed to waive a portion of its management fee and/or reimburse expenses for certain funds of the John Hancock complex, including the participating portfolios. The waiver equaled, on an annualized basis, 0.01% of that portion of the aggregate net assets of all the participating portfolios that exceeded $75 billion but was less than or equal to $125 billion; 0.0125% of that portion of the aggregate net assets of all the participating

22


portfolios that exceeded $125 billion but was less than or equal to $150 billion; and 0.015% of that portion of the aggregate net assets of all the participating portfolios that exceeded $150 billion. The amount of the reimbursement was calculated daily and allocated among all the participating portfolios in proportion to the daily net assets of each fund.

The expense reductions described above amounted to $31,761 for the six months ended January 31, 2015.

The investment management fees, including the impact of the waivers and reimbursements as described above, incurred for the six months ended January 31, 2015 were equivalent to a net annual effective rate of 0.74% of the fund's average daily managed assets.

Accounting and legal services. Pursuant to a service agreement, the fund reimburses the Advisor for all expenses associated with providing the administrative, financial, legal, accounting and recordkeeping services to the fund, including the preparation of all tax returns, periodic reports to shareholders and regulatory reports, among other services. These accounting and legal services fees incurred for the six months ended January 31, 2015 amounted to an annual rate of 0.02% of the fund's average daily managed assets.

Trustee expenses. The fund compensates each Trustee who is not an employee of the Advisor or its affiliates. Each independent Trustee receives from the fund and the other John Hancock closed-end funds an annual retainer. In addition, Trustee out-of-pocket expenses are allocated to each fund based on its net assets relative to other funds within the John Hancock group of funds complex.

Note 6 — Leverage risk

The fund utilizes a Credit Facility Agreement (CFA) to increase its assets available for investment. When the fund leverages its assets, common shareholders bear the fees associated with the CFA and have potential to benefit or be disadvantaged from the use of leverage. The Advisor's fee is also increased in dollar terms from the use of leverage. Consequently, the fund and the Advisor may have differing interests in determining whether to leverage the fund's assets. Leverage creates risks that may adversely affect the return for the holders of common shares, including:

the likelihood of greater volatility of net asset value and market price of common shares;
fluctuations in the interest rate paid for the use of the credit facility;
increased operating costs, which may reduce the fund's total return;
the potential for a decline in the value of an investment acquired through leverage, while the fund's obligations under such leverage remains fixed; and
the fund is more likely to have to sell securities in a volatile market in order to meet asset coverage or other debt compliance requirements.

To the extent the income or capital appreciation derived from securities purchased with funds received from leverage exceeds the cost of leverage, the fund's return will be greater than if leverage had not been used, conversely, returns would be lower if the cost of the leverage exceeds the income or capital appreciation derived.

In addition to the risks created by the fund's use of leverage, the fund is subject to the risk that it would be unable to timely, or at all, obtain replacement financing if the CFA is terminated. Were this to happen, the fund would be required to de-leverage, selling securities at a potentially inopportune time and incurring tax consequences. Further, the fund's ability to generate income from the use of leverage would be adversely affected.

Note 7 — Credit facility agreement

The fund has entered into a CFA with a subsidiary of BNP Paribas (BNP) that allows it to borrow up to $292.5 million (maximum facility amount) and to invest the borrowings in accordance with its investment practices.

The fund pledges a portion of its assets as collateral to secure borrowings under the CFA. Such pledged assets are held in a special custody account with the fund's custodian. The amount of assets required to be pledged by the fund is determined in accordance with the CFA. The fund retains the benefits of ownership of assets pledged to secure borrowings under the CFA. Interest charged is at the rate of one month LIBOR (London Interbank Offered Rate) plus 0.70% and is payable monthly. As of

23


January 31, 2015, the fund had borrowings of $292,500,000 at an interest rate of 0.87%, which are reflected in the CFA payable on the Statement of assets and liabilities. During the six months ended January 31, 2015, the average borrowings under the CFA and the effective average interest rate were $292,500,000 and 0.87%, respectively.

The fund is required to pay a commitment fee equal to 0.60% on any unused portion of the maximum facility amount, only for days on which the aggregate outstanding amount of the loans under the CFA is less than 80% of the maximum facility amount. The commitment fee for the six months ended January 31, 2015 amounted to $0.

The fund may terminate the CFA with 30 days' notice. If certain asset coverage and collateral requirements, minimum net assets or other covenants are not met, the CFA could be deemed in default and result in termination. Absent a default or facility termination event, BNP generally is required to provide the fund with 360 days' notice prior to terminating or amending the CFA.

The fund has an agreement with BNP that allows BNP to borrow a portion of the pledged collateral (Lent Securities) in an amount not to exceed the lesser of: (i) outstanding borrowings owed by the fund to BNP and (ii) 331/ 3 % of the fund's total assets. The fund can designate any security within the pledged collateral as ineligible to be a Lent Security and can recall any of the Lent Securities. The fund also has the right to apply and set-off an amount equal to 100% of the then-current fair market value of such Lent Securities against the current borrowings under the CFA in the event that BNP fails to timely return the Lent Securities and in certain other circumstances. In such circumstances, however, the fund may not be able to obtain replacement financing required to purchase replacement securities and, consequently, the fund's income generating potential may decrease. Even if the fund is able to obtain replacement financing, it might not be able to purchase replacement securities at favorable prices. Income earned from Lent Securities of $0 for the six months ended January 31, 2015 is recorded as a component of interest income on the Statement of operations.

Note 8 — Purchase and sale of securities

Purchases and sales of securities, other than short-term investments, amounted to $27,759,765 and $28,029,492, respectively, for the six months ended January 31, 2015.
