A message to shareholders

Dear shareholder,

The financial markets delivered strong returns during first half of the 12-month period ended July 31, 2020; however, heightened fears over the coronavirus (COVID-19) sent markets tumbling during the latter half of February and early March. Yet by the end of the first quarter, equity markets began to rise—and this comeback gathered momentum during the final four months of the period; however, holdings of preferred shares in certain market segments did not participate fully in the rebound.

Of course, it would be a mistake to consider this market turnaround a trustworthy signal of assured or swift economic recovery. While there has been economic growth in most of the United States, the pace has slowed in many areas as spending remains far below pre-pandemic levels.

From an investment perspective, we continue to think that maintaining a focus on long-term objectives while pursuing a risk-aware strategy is a prudent way forward. Above all, we believe the counsel of a trusted financial professional continues to matter now more than ever. Periods of heightened uncertainty are precisely the time to review your financial goals and follow a plan that helps you make the most of what continues to be a challenging situation. 

On behalf of everyone at John Hancock Investment Management, I'd like to take this opportunity to welcome new shareholders and thank existing shareholders for the continued trust you've placed in us. 

Sincerely,

ANDREWARNOTT_SIG.JPG

Andrew G. Arnott
President and CEO,
John Hancock Investment Management
Head of Wealth and Asset Management,

INVESTMENT OBJECTIVE


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

AVERAGE ANNUAL TOTAL RETURNS AS OF 7/31/2020 (%)

The ICE Bank of America Hybrid Preferred Securities Index is a subset of the ICE Bank of America Fixed Rate Preferred Securities Index, including all subordinated securities with a payment deferral feature. The ICE Bank of America 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 the country of risk must also have an investment-grade rating.

It is not possible to invest directly in an index. Index figures do not reflect expenses or sales charges, which would result in lower returns.

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

Investment returns and principal value will fluctuate and a shareholder may sustain losses. Further, the fund's performance at net asset value (NAV) is different from the fund's performance at closing market price because the closing market price is subject to the dynamics of secondary market trading. Market risk may be increased when shares are purchased at a premium to NAV or sold at a discount to NAV. Current month-end performance may be higher or lower than the performance cited. The fund's most recent performance can be found at jhinvestments.com or by calling 800-852-0218.

PERFORMANCE HIGHLIGHTS OVER THE LAST TWELVE MONTHS


The spread of COVID-19 was the key driver of the preferred market's performance

After benefiting from a period of relative calm from August 2019 through January 2020, preferred securities came under severe pressure during the global markets sell-off in March 2020.

Energy holdings hurt performance

A decline in energy demand, an effect of the pandemic, hampered the fund's return.

Communication services holdings boosted relative performance

Investors' demand for companies benefiting from the work-from-home trend helped telecommunications holdings.

A note about risks

As is the case with all exchange-listed closed-end funds, shares of this fund may trade at a discount or a premium 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 tax return of capital. A return of capital is the return of all or a portion of a shareholder's investment in the fund. For the fiscal year ended July 31, 2020, the fund's aggregate distributions included a return of capital of $0.08 per share, or 5.07% of aggregate distributions, which could impact the tax treatment of a subsequent sale of fund shares. 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. Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market value of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily on the underlying common stock's value. Investments in higher-yielding, lower-rated securities are subject to a higher risk of default. An issuer of securities held by the fund may default, have its credit rating downgraded, or otherwise perform poorly, which may affect fund performance. Liquidity—the extent to which a security may be sold or a derivative position closed without negatively affecting its market value—may be impaired by reduced trading volume, heightened volatility, rising interest rates, and other market conditions. Domestic and foreign equity markets have experienced increased volatility and turmoil which may adversely affect the fund and issuers worldwide. 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. In addition, in volatile market environments, the fund could be required to sell securities in the portfolio in order to comply with regulatory or other debt compliance requirements, which could negatively impact the fund's performance. 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.

A widespread health crisis such as a global pandemic could cause substantial market volatility, exchange trading suspensions and closures,and affect fund performance. For example, the novel coronavirus disease (COVID-19) has resulted in significant disruptions to global business activity. The impact of a health crisis and other epidemics and pandemics that may arise in the future, could affect the global economy in ways that cannot necessarily be foreseen at the present time. A health crisis may exacerbate other pre-existing political, social, and economic risks. Any such impact could adversely affect the fund's performance, resulting in losses to your investment.

The fund normally will invest at least 25%, measured at the time of purchase, of its total assets in the industries composing the utilities sector, which includes telecommunications companies. 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. Cybersecurity incidents 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 affect performance.

Manager's discussion of fund performance

How would you describe the investment backdrop during the 12 months ended July 31, 2020?

Preferred securities suffered significant losses for the period, hamstrung by poor performance during late February and throughout March when growing investor anxiety over the COVID-19 pandemic led to extreme global market volatility, with preferreds hit particularly hard. April marked the beginning of a robust rebound that persisted through period end, triggered largely by the U.S. Federal Reserve's (Fed's) moves to cut interest rates and restore liquidity to financial markets, as well as fiscal stimulus designed to shore up the U.S. economy. Even after this late period rally, many preferreds still hadn't fully recovered from their March lows by period end as they tend to be issued by energy, utilities, and financial services firms that saw their values hurt by the pandemic.

What elements of the fund's positioning affected results?

The fund's overweighting in the energy sector detracted from performance relative to its comparative index, the ICE Bank of America Hybrid Preferred Securities Index. The energy sector performed poorly as investors began to discount future energy demand in light of the forced pandemic-related shutdown of the economy. Even the midstream energy companies—firms that process, store, and transport oil and gas—were caught up in the sector's decline, even though they tend to be less sensitive to commodity prices.

Also detracting from performance were sales of Kinder Morgan, Inc. and Stanley Black & Decker, Inc. These sales permitted a reduction of the fund's leverage in March, a strategy we pursued to manage the portfolio's overall risk profile. Given the weak market environment at the time, the sale of these securities resulted in losses for the fund.

In contrast, the fund's overweighting in the communication services sector contributed, with holdings in U.S. Cellular Corp. and Telephone and Data Systems, Inc. adding value amid investors' search for companies that would benefit from the work-from-home trend. Elsewhere, the fund's overweighting in electric utility preferreds further boosted relative performance.

How was the fund positioned at the end of the period?

We believe preferred securities will continue to recover over the next 6 to 12 months. We think interest rates will remain low given the economic impact of the coronavirus and that it will be some time before the Fed decides to raise rates for fear of derailing a recovery. The yields on preferreds looked very attractive relative to the 10-year U.S. Treasury bond as of the end of July, at wide levels not seen since the 2008 financial crisis. As the economy slowly goes back to normal, we expect this spread to revert to the historical mean, which will likely provide significant upside to preferred securities. The credit quality of the average preferred issue is very good, in our view, at an average of investment grade. We believe that, over time, preferreds' credit quality and attractive valuations will be recognized by the market and result in price appreciation for the asset class.

Notes to financial statements
Note 1Organization
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 2Significant 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 scheduled close of regular trading on the New York Stock Exchange (NYSE), normally at 4:00 P.M., Eastern Time. In case of emergency or other disruption resulting in the NYSE not opening for trading or the NYSE closing at a time other than the regularly scheduled close, the net asset value (NAV) may be determined as of the regularly scheduled close of the NYSE pursuant to the fund's Valuation Policies and Procedures.
In order to value the securities, the fund uses the following valuation techniques: Equity securities, including exchange-traded or closed-end funds, are typically valued at the last sale price or official closing price on the exchange or principal market where the security trades. 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 typically valued based on evaluated prices provided by an independent pricing vendor. 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. Futures contracts are typically valued at the last traded price on the exchange on which they trade. Swaps are generally valued using evaluated prices obtained from an independent pricing vendor.
In certain instances, the Pricing Committee may determine to value equity securities using prices obtained from another exchange or market if trading on the exchange or market on which prices are typically obtained did not open for trading as scheduled, or if trading closed earlier than scheduled, and trading occurred as normal on another exchange or market.
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.
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, including registered investment companies. 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 and related inputs 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, or for tri-party repurchase agreements, collateral is held at a third-party custodian bank in a segregated account for the benefit of the fund. 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, assets and liabilities resulting from repurchase agreements are not offset 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 claims resulting from close-out of the transactions.
22 JOHN HANCOCK PREFERRED INCOME FUND |ANNUAL REPORT  

 

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.
Security transactions and related investment income. Investment security transactions are accounted for on a trade date plus one basis for daily NAV 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 certain 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. Non-cash dividends, if any, are recorded at the fair market value of the securities received. Distributions received on securities that represent a tax return of capital and/or capital gain, if any, are recorded as a reduction of cost of investments and/or as a realized gain, if amounts are estimable. Gains and losses on securities sold are determined on the basis of identified cost and may include proceeds from litigation.
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.
Statement of cash flows. A Statement of cash flows is presented when a fund has a significant amount of borrowing during the period, based on the average total borrowing in relation to total assets, or when a certain percentage of the fund’s investments is classified as Level 3 in the fair value hierarchy. 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 or collateral on derivative contracts, if any.
Change in accounting principle. Accounting Standards Update (ASU) 2017-08, Premium Amortization on Purchased Callable Debt Securities, shortens the premium amortization period for purchased non contingently callable debt securities and is effective for public companies with fiscal years beginning after December 15, 2018. Adoption of the ASU did not have a material impact to the fund.
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.
For federal income tax purposes, as of July 31, 2020, the fund has a short-term capital loss carryforward of $8,647,239 and a long-term capital loss carryforward of $18,616,520 available to offset future net realized capital gains. These carryforwards do not expire.
  ANNUAL REPORT |JOHN HANCOCK PREFERRED INCOME FUND 23

 

As of July 31, 2020, 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. Capital gain distributions, if any, are typically distributed annually.
The tax character of distributions for the years ended July 31, 2020 and 2019 was as follows:
  July 31, 2020 July 31, 2019
Ordinary income $37,561,339 $36,386,401
Return of capital 2,007,312 7,360,791
Total $39,568,651 $43,747,192
As of July 31, 2020, there were no distributable earnings on a tax basis.
Such distributions and distributable earnings, on a tax basis, are determined in conformity with income tax regulations, which may differ from US GAAP. Distributions in excess of tax basis earnings and profits, if any, are reported in the fund's financial statements as a return of capital.
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 contingent payment debt instruments, amortization and accretion on debt securities and derivative transactions.
Note 3Derivative instruments
The fund may invest in derivatives in order to meet its investment objective. Derivatives include a variety of different instruments that may be traded in the over-the-counter (OTC) 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 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.
Certain derivatives are traded or cleared on an exchange or central clearinghouse. Exchange-traded or centrally-cleared transactions generally present less counterparty risk to a fund than OTC transactions. The exchange or clearinghouse stands between the fund and the broker to the contract and therefore, credit risk is generally limited to the failure of the exchange or clearinghouse and the clearing member.
Centrally-cleared swap contracts are subject to clearinghouse rules, including initial and variation margin requirements, daily settlement of obligations and the clearinghouse guarantee of payments to the broker. There is, however, still counterparty risk due to the potential insolvency of the broker with respect to any margin held in the brokers’ customer accounts. While clearing members are required to segregate customer assets from their own assets, in the event of insolvency, there may be a shortfall in the amount of margin held by the broker for its clients. Collateral or margin requirements for centrally-cleared derivatives are set by the broker or applicable clearinghouse. Margin for centrally-cleared transactions is detailed in the Statement of assets and liabilities as Receivable/Payable for centrally-cleared swaps. Securities pledged by the fund for centrally-cleared transactions, if any, are identified in the Fund's investments.
24 JOHN HANCOCK PREFERRED INCOME FUND |ANNUAL REPORT  

 

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. Futures are traded on an exchange and cleared through a central clearinghouse. Risks related to the use of futures contracts include possible illiquidity of the futures markets and 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 set by the broker and is generally based on a percentage of the contract value. The margin deposit must then be maintained at the established level over the life of the contract. Cash that has been pledged by the fund is detailed in the Statement of assets and liabilities as Collateral held at broker for futures contracts. Securities pledged by the fund, if any, are identified in the Fund's investments. Subsequent payments, referred to as variation margin, are made or received by the fund periodically and are based on changes in the market value of open futures contracts. Futures contracts are marked-to-market daily and unrealized gain or loss is recorded by the fund. Payable for futures variation margin is included on the Statement of assets and liabilities. 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 year ended July 31, 2020, the fund used futures contracts to manage against anticipated interest rate changes. The fund held futures contracts with USD notional values ranging from $81.6 million to $89.7 million, as measured at each quarter end.
Swaps. Swap agreements are agreements between the fund and a counterparty to exchange cash flows, assets, foreign currencies or market-linked returns at specified intervals. Swap agreements are privately negotiated in the OTC market (OTC swaps) 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 a component of unrealized appreciation/depreciation of swap contracts. The value of the swap will typically impose collateral posting obligations on the party that is considered out-of-the-money on the swap.
Upfront payments made/received by the fund, if any, are amortized/accreted for financial reporting purposes, with the unamortized/unaccreted portion included in the Statement of assets and liabilities. 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.
Entering into swap agreements involves, to varying degrees, elements of credit, market and documentation risk that may provide outcomes 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. In addition to interest rate risk, market risks may also impact the swap. The fund may also suffer losses if it is unable to terminate or assign outstanding swaps or reduce its exposure through offsetting transactions.
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.
During the year ended July 31, 2020, the fund used interest rate swap contracts to manage against anticipated interest rate changes. The notional values at the period end are representative of the fund's exposure throughout the period. No new interest rate swap positions were entered into or closed during the year ended July 31, 2020.

Note 4Guarantees 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 5Fees and transactions with affiliates
John Hancock Investment Management LLC (the Advisor) serves as investment advisor for the fund. The Advisor is an indirect, principally 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, equivalent on an annual basis, to 0.75% of the fund’s average daily managed assets including any assets attributable to the Credit Facility Agreement (see Note 7) (collectively, managed assets). The Advisor has a subadvisory agreement with Manulife Investment 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.
26 JOHN HANCOCK PREFERRED INCOME FUND |ANNUAL REPORT  

 

The Advisor has contractually agreed to waive a portion of its management fee and/or reimburse expenses for certain funds of the John Hancock group of funds complex, including the fund (the participating portfolios). This waiver is based upon aggregate net assets of all the participating portfolios. 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. During the year ended July 31, 2020, this waiver amounted to 0.01% of the fund’s average daily net assets. This arrangement expires on July 31, 2022, 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.
The expense reductions described above amounted to $56,216 for the year ended July 31, 2020.
Expenses waived or reimbursed in the current fiscal period are not subject to recapture in future fiscal periods.
The investment management fees, including the impact of the waivers and reimbursements as described above, incurred for the year ended July 31, 2020, 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, compliance, 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 year ended July 31, 2020, amounted to an annual rate of 0.01% 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. These Trustees receive 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 6Leverage risk
The fund utilizes a Credit Facility Agreement (CFA) to increase its assets available for investment. When the fund leverages its assets, shareholders bear the expenses 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 shares, including:
the likelihood of greater volatility of NAV and market price of shares;
fluctuations in the interest rate paid for the use of the CFA;
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.
  ANNUAL REPORT |JOHN HANCOCK PREFERRED INCOME FUND 27

 

Note 7Credit Facility Agreement
The fund has entered into a Credit Facility Agreement (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 July 31, 2020, the fund had borrowings of $235,500,000 at an interest rate of 0.85%, which are reflected in the Credit facility agreement payable on the Statement of assets and liabilities. During the year ended July 31, 2020, the average borrowings under the CFA and the effective average interest rate were $271,908,219 and 2.06%, 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. For the year ended July 31, 2020, there were no commitment fees incurred by the fund.
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 or (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 $37,398 for the year ended July 31, 2020 is recorded as a component of interest income on the Statement of operations.
Due to the anticipated discontinuation of LIBOR, as discussed in Note 8, the CFA may be amended to remove LIBOR as the reference rate for interest and to replace LIBOR with an alternative reference rate for interest mutually agreed upon by the fund and BNP. However, there remains uncertainty regarding the future utilization of LIBOR and the nature of any replacement rate and the potential effect of a transition away from LIBOR on the fund and/or the CFA cannot yet be fully determined.
Note 8LIBOR Discontinuation Risk
The CFA utilizes LIBOR as the reference or benchmark rate for interest rate calculations. LIBOR is a measure of the average interest rate at which major global banks can borrow from one another. Following allegations of rate manipulation and concerns regarding its thin liquidity, in July 2017, the U.K. Financial Conduct Authority, which regulates LIBOR, announced that it will stop encouraging banks to provide the quotations needed to sustain LIBOR after 2021. This event will likely cause LIBOR to cease to be published. Before then, it is expected that market participants such as the fund and BNP will transition to the use of different reference or benchmark rates. However, although regulators have suggested alternative rates, there is currently no definitive information regarding the future utilization of LIBOR or of any replacement rate.
It is uncertain what impact the discontinuation of LIBOR will have on the use of LIBOR as a reference rate in the
28 JOHN HANCOCK PREFERRED INCOME FUND |ANNUAL REPORT  

 

CFA. It is expected that market participants will amend financial instruments referencing LIBOR, such as the CFA, to include fallback provisions and other measures that contemplate the discontinuation of LIBOR or other similar market disruption events, but neither the effect of the transition process nor the viability of such measures is known. In addition, there are obstacles to converting certain longer term securities and transactions to a new benchmark or benchmarks and the effectiveness of one alternative reference rate versus multiple alternative reference rates in new or existing financial instruments and products has not been determined. As market participants transition away from LIBOR, LIBOR's usefulness may deteriorate, which could occur prior to the end of 2021. The transition process may lead to increased volatility and illiquidity in markets that currently rely on LIBOR to determine interest rates. LIBOR's deterioration may adversely affect the liquidity and/or market value of securities that use LIBOR as a benchmark interest rate. The use of an alternative reference rate, or the transition process to an alternative reference rate, may result in increases to the interest paid by the fund pursuant to the CFA and, therefore, may adversely affect the fund's performance.
Note 9Purchase and sale of securities
Purchases and sales of securities, other than short-term investments, amounted to $269,055,015 and $337,989,987, respectively, for the year ended July 31, 2020.
Note 10Industry or sector risk
The fund generally invests a large percentage of its assets in one or more particular industries or sectors of the economy. If a large percentage of the fund's assets are economically tied to a single or small number of industries or sectors of the economy, the fund will be less diversified than a more broadly diversified fund, and it may cause the fund to underperform if that industry or sector underperforms. In addition, focusing on a particular industry or sector may make the fund’s NAV more volatile. Further, a fund that invests in particular industries or sectors is particularly susceptible to the impact of market, economic, regulatory and other factors affecting those industries or sectors. Financial services companies can be hurt by economic declines, changes in interest rates regulatory and market impacts.
Note 11Coronavirus (COVID-19) pandemic
The novel COVID-19 disease has resulted in significant disruptions to global business activity. A widespread health crisis such as a global pandemic could cause substantial market volatility, exchange trading suspensions and closures, and affect fund performance.
