CEO corner

To Our Shareholders,

The stock market gained solid ground over the 12 months ending July 31, 2007, returning 16.13%, as measured by the Standard & Poor’s 500 Index. It was bolstered by stronger-than-expected corporate earnings growth, healthy global economic growth and robust merger and acquisitions activity. These positives served to overcome concerns about inflation, a slumping housing market and the subprime mortgage debacle that caused heightened volatility, a market downturn and negative results for June and July.

Interestingly, during this period the stock market passed a significant milestone, when the broad Standard & Poor’s 500 Index climbed beyond the record it had set seven years ago. From its peak in March 2000, the stock market spiraled downward three consecutive years, bottoming in 2002. The upturn began in 2003, and the market has advanced each year since, finally setting a new high for the first time on May 30, 2007.

This nearly complete market cycle highlights the importance of two investment principles you have heard us speak of often: diversification and patience. By allocating your investments among different asset classes, investment styles and portfolio managers, you are likely to be well represented through all phases of a complete market cycle, with the winners helping to cushion the fall of the losers.

The challenge for investors with a diversified portfolio is to properly evaluate your investments to tell the difference between an underperforming manager and an out-of-favor style, while also understanding the role each investment plays in your portfolio. That’s where your financial professional can provide true value. He or she can help you make those assessments and also counsel patience, because a properly diversified portfolio by its very nature will typically have something lagging or out of favor — a concept that can be difficult to live with, but necessary to embrace. If everything in your portfolio is “working,” then you are not truly diversified, but rather are leveraged to the current market and the flavor of the day. If so, you are bound to be out of step in the near future.

With the recent volatility in the securities markets, it has prompted many investors to question how long this type of market cycle will last. History tells us it will end and that when it does, today’s leaders may well turn into laggards and vice versa. Indeed, the subprime mortgage market woes are just the latest example of why investors should be well-diversified. For with patience and a diversified portfolio, it could be easier to weather the market’s twists and turns and reach your long-term goals. Sincerely,


Keith F. Hartstein,
President and Chief Executive Officer

Your fund at a glance

The Fund seeks to provide a high level of current income, consistent with preservation of capital, by investing in a diversified portfolio of securities that, in the opinion of the Adviser, may be undervalued relative to similar securities in the marketplace. Under normal market conditions, the Fund invests at least 80% of its assets in preferred stocks and other preferred securities.

Over the last twelve months

Preferred stocks generated gains during the period, thanks to the income they produced.

The Fund outperformed its Morningstar, Inc. peer group of long-term bond funds on a net asset value basis.

The Fund benefited from sidestepping the pain associated with hard-hit sectors, such as REITs, mortgage lenders and below-investment-grade securities.

Managers’ report

John Hancock
Preferred Income Fund

Despite posting very strong gains early on, market volatility toward the end of the 12-month period ended July 31, 2007 significantly curtailed the performance of preferred stocks. From early August 2006 through the end of that year, preferred stocks rallied strongly, bolstered first by optimism that the Federal Reserve Board would hold interest rates steady, and later by growing hopes that the central bank might actually cut rates in the first half of 2007. Because preferreds make fixed-income payments in the form of dividends, their prices tend to move higher and lower in response to expectations for interest rates and inflation. Also bolstering preferreds during that time span was an abatement in new issuance, as issuers called (meaning they refunded) outstanding preferred securities.

In the first calendar quarter of 2007, preferreds continued to post strong returns. A series of reports indicating that the housing market and other parts of the economy were slowing provided investors evidence that inflation wasn’t the same concern it had been just a few months earlier.

Preferreds weakened a bit in the spring, amid growing concerns that any interest rate cuts might be further off than most observers had originally anticipated. Additionally, a resurgence in the supply of the securities once again acted as a drag on their prices. Conditions got decidedly worse in June and July, when worries about delinquencies among subprime mortgage borrowers prompted investors to re-price risk. That

re-pricing led to lower prices for nearly all asset classes relative to safe-haven U.S. Treasury securities, which benefited from a global flight to quality.

As a result of the weakness they experienced in June and July, many preferred stocks suffered price declines, but they still managed to post gains for the year because the price depreciation they suffered was more than offset by the income they generated in that time.

“Despite posting very strong gains
early on, market volatility toward
the end of the 12-month period
ended July 31, 2007 significantly
curtailed the performance of
preferred stocks.”

Performance

For the 12 months ended July 31, 2007, John Hancock Preferred Income Fund returned 5.46% at net asset value (NAV) and 4.56% at market value. The difference in the Fund’s NAV performance and its market performance stems from the fact that the market share price is subject to the dynamics of secondary market trading, which could cause it to trade at a discount or premium to the Fund’s NAV share price at any time. By comparison, the average long-term closed-end bond fund returned 3.26% at NAV, according to Morningstar, Inc. For the same 12-month period, the Lehman Brothers Aggregate Bond Index gained 5.58% and the Merrill Lynch Preferred Stock Hybrid Securities Index rose 3.07% . The Fund’s yield at closing market price on July 31, 2007 was 8.19% .

Leaders and laggards

In a period when most preferred stock prices declined, some of our holdings that performed best were those that were called — meaning redeemed — by their issuer prior to maturity. For example, our stakes in Dominion CNG and Northern States Power Co. were two of our best performers for the year because they were called at an attractive premium

to their then-market prices. Our holdings in Virginia Power Capital Trust preferred stock also performed well, helped by the announcement that the company would continue to redeem debt and preferred stocks later this year. Elsewhere, another standout was Nexen, Inc., a large Canadian oil and gas producer, which benefited from improved profitability on the tail of higher oil prices.

Risk aversion

With the significant increase in volatility, sometimes what you don’t own can be just as important as what you do own. Such was the case for us, particularly during the final months of the period. We had no exposure to mortgage lenders, which investors pummeled in response to the subprime mortgage market meltdown. We also were helped by the fact that we had very little exposure to real estate investment trusts (REITs). Investors seemingly turned their backs on the sector because they were worried that after a seven-year stretch of outperformance, REITs were due for a correction. We believe that the selling in REITs was too indiscriminate, and that the few REITs we held — namely Duke Realty Corp., which is largely an office building owner, and Public Storage, Inc., a provider of self-storage units — would likely continue to benefit from strong economic fundamentals and their respective track records of boosting shareholder value.

Our ongoing emphasis on high-quality companies also served us well. The June/July market sell-off greatly punished below-investment-grade companies, where our exposure was quite light. Finally, we benefited from not owning floating-rate preferred securities. Hedge funds, which had become large holders of this particular type of preferred security, were forced to dump them in the summer downturn to cover losses elsewhere.

We lost ground with our stake in student-loan company SLM Corp. Investors initially became concerned about a potential credit downgrade of the company amid news about the financing details of the company’s agreement to be taken private in a leveraged buyout (LBO). Of particular concern

was the high level of debt that would have to be serviced through cash flow from operations. Later, SLM was hurt by worries that the planned LBO of the company was in danger as credit markets froze. We continued to hold on to SLM because we believe the preferred stock’s price reflected the worst-case scenario, and we weren’t willing to part with it at such discounted valuations.

“In a period when most preferred
stock prices declined, some of our
holdings that performed
best were those that were
called — meaning redeemed —
by their issuer prior to maturity.”

Outlook

By the end of the period, Treasury bonds were priced such that investors were expecting a rate cut imminently. We agree that the Fed’s next move will be to lower the federal funds’ rate rather than raise it and we believe it could occur some time in the third quarter, barring any spikes in inflation. By our estimates, the financial markets are about halfway through the process of re-pricing risk. Once this sometimes painful process is completed, we look for better performance from investment-grade securities — including the preferred stocks we tend to favor. Over the longer-term, we remain optimistic that gradually slowing economic conditions will bode well for fixed-income investments, including preferred stocks, and that long-term demand for income-producing stocks will provide support for them.


This commentary reflects the views of the portfolio management team through the end of the Fund’s period discussed in this report. The team’s statements reflect its own opinions. As such they are in no way guarantees of future events and are not intended to be used as investment advice or a recommendation regarding any specific security. They are also subject to change at any time as market and other conditions warrant.

The Fund normally will invest at least 25% of its managed assets in securities of companies in the utilities industry. Such an investment concentration makes the Fund more susceptible than a more broadly diversified fund to factors adversely affecting the utilities industry. Sector investing is subject to greater risks than the market as a whole.

International investing involves special risks such as political, economic and currency risks and differences in accounting standards and financial reporting.

Notes to financial statements

Note 1
Accounting policies

John Hancock Preferred Income Fund (the Fund) is a diversified closed-end management investment company registered under the Investment Company Act of 1940, as amended (the 1940 Act).

Significant accounting policies of the Fund are as follows:

Security valuation

The net asset value of the common shares of the Fund is determined daily as of the close of the New York Stock Exchange (NYSE), normally at 4:00 p.m., Eastern Time. Short-term debt investments that have a remaining maturity of 60 days or less are valued at amortized cost, and thereafter assume a constant amortization to maturity of any discount or premium, which approximates market value. All other securities held by the Fund are valued at the last sale price or official closing price (closing bid price or last evaluated quote if no sale has occurred) as of the close of business on the principal securities exchange (domestic or foreign) on which they trade or, lacking any sales, at the closing bid price. Securities traded only in the over-the-counter market are valued at the last bid price quoted by brokers making markets in the securities at the close of trading. Securities for which there are no such quotations, principally debt securities, are valued based on the valuation provided by an independent pricing service, which utilizes both dealer-supplied and electronic data processing techniques, which take 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.

Other assets and securities for which no such quotations are readily available are valued at fair value as determined in good faith under consistently applied procedures established by and under the general supervision of the Board of Trustees. Generally, trading in non-U.S. securities is substantially completed each day at various times prior to the close of trading on the NYSE. The values of such securities used in computing the net asset value of the Fund’s shares are generally determined as of such times. Occasionally, significant events that affect the values of such securities may occur between the times at which such values are generally determined and the close of the NYSE. Upon such an occurrence, these securities will be valued at fair value as determined in good faith under consistently applied procedures established by and under the general supervision of the Board of Trustees.

Investment transactions

Investment 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. Net realized gains and losses on sales of investments are determined on the identified cost basis.

Discount and premium on securities

The Fund utilizes the level yield method to accrete discount and amortize premium from par value on securities from either the date of issue or the date of purchase over the life of the security.

Expenses

The majority of expenses are directly identifiable to an individual fund. Expenses that are not readily identifiable to a specific fund are allocated in such a manner as deemed equitable, taking into consideration, among other things, the nature and type of expense and the relative size of the funds.

Financial futures contracts

The Fund may buy and sell financial futures contracts. Buying futures tends to increase the Fund’s exposure to the underlying instrument.

Preferred Income Fund

16


Selling futures tends to decrease the Fund’s exposure to the underlying instrument or hedge other Fund’s instruments. Initial margin deposits required upon entering into futures contracts are satisfied by the delivery of specific securities or cash as collateral to the broker (the Fund’s agent in acquiring the futures position). Each day, the futures contract is valued at the official settlement price of the board of trade or U.S. commodities exchange on which it trades. Subsequent payments to and from the broker, known as “variation margin,” are made on a daily basis as the market price of the financial futures contract fluctuates. Daily variation margin adjustments arising from this “mark to market” are recorded by the Fund as unrealized gains or losses.

When the contracts are closed, the Fund recognizes a gain or loss. Risks of entering into financial futures contracts include the possibility that there may be an illiquid market and/or that a change in the value of the contracts may not correlate with changes in the value of the underlying securities. In addition, the Fund could be prevented from opening or realizing the benefits of closing out financial futures positions because of position limits or limits on daily price fluctuation imposed by an exchange.

For federal income tax purposes, the amount, character and timing of the Fund’s gains and/or losses can be affected as a result of financial futures contracts. On July 31, 2007, the Fund had deposited $571,200 with the broker to cover margin requirements on open financial futures contracts.

The Fund had the following financial futures contracts open on July 31, 2007:

  NUMBER OF      UNREALIZED   
OPEN CONTRACTS  CONTRACTS  POSITION  EXPIRATION  APPRECIATION   

U.S. Treasury 10-Year Note  252  Short  Sep 2007  $75,015   
U.S. Treasury 10-Year Note  420  Short  Sep 2007  125,026   
        $200,041   

Swap contracts

The Fund may enter into swap transactions in order to hedge the value of the Fund’s portfolio against interest rate fluctuations or to enhance the Fund’s income. Interest rate swaps represent an agreement between two counter-parties to exchange cash flows based on the difference in the two interest rates, applied to the notional principal amount for a specified period. 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 receivable or payable under the swap contracts on a periodic basis.

The Fund records changes in the value of the swaps as unrealized gains or losses on swap contracts. Net periodic payments accrued, but not yet received (paid) are included in change in the unrealized appreciation/ depreciation on the Statement of Operations.

Swap contracts are subject to risks related to the counterparty’s ability to perform under the contract, and may decline in value if the counterparty’s creditworthiness deteriorates. The risks may arise from unanticipated movement in interest rates. The Fund may also suffer losses if it is unable to terminate outstanding swap contracts or reduce its exposure through offsetting transactions.

Federal income taxes

The Fund qualifies 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.

New accounting pronouncements

In June 2006, Financial Accounting Standards Board (FASB) Interpretation No. 48, Accounting for Uncertainty in Income Taxes (the Interpretation) was issued, and is effective for fiscal years beginning after December 15, 2006 and is to be applied to all open tax years as of the effective date. This Interpretation prescribes a minimum threshold for financial statement recognition of the benefit of a tax position taken or expected to be taken in a tax return, and requires certain expanded disclosures. Management has evaluated the application of the Interpretation to the Fund and does not believe there is a material impact resulting from adoption of this Interpretation on the Fund’s financial statements.

In September 2006, FASB Standard No. 157, Fair Value Measurements (FAS 157) was issued, and is effective for fiscal years beginning after November 15, 2007. FAS 157 defines fair value, establishing a framework for measuring fair value and expands disclosure about fair value measurements. Management is currently evaluating the application of FAS 157 to the Fund, and its impact, if any, resulting from the adoption of FAS 157 on the Fund’s financial statements.

Dividends, interest and distributions

Dividend income on investment securities is recorded on the ex-dividend date or, in the case of some foreign securities, on the date thereafter when the Fund identifies the dividend. Interest income on investment securities is recorded on the accrual basis. Foreign income may be subject to foreign withholding taxes, which are accrued as applicable.

The Fund records distributions from net investment income and net realized gains on the ex-dividend date. During the year ended July 31, 2006, the tax character of distributions paid was as follows: ordinary income $58,813,871 and long-term capital gains $5,805,895. During the year ended July 31, 2007, the tax character of distributions paid was as follows: ordinary income $64,184,566 and long-term capital gains $3,360,268.

As of July 31, 2007, the components of distributable earnings on a tax basis included $7,145,840 of undistributed ordinary income and $3,947,882 of undistributed long-term gain.

Such distributions and distributable earnings, on a tax basis, are determined in conformity with income tax regulations, which may differ from accounting principles generally accepted in the United States of America. Distributions in excess of tax basis earnings and profits, if any, are reported in the Fund’s financial statements as a return of capital.

Use of estimates

The preparation of these financial statements, in accordance with accounting principles generally accepted in the United States of America, incorporates estimates made by management in determining the reported amount of assets, liabilities, revenues and expenses of the Fund. Actual results could differ from these estimates.

Note 2
Management fee and transactions with
affiliates and others

The Fund has an investment management contract with John Hancock Advisers, LLC (the Adviser), a wholly owned subsidiary of the John Hancock Financial Services, Inc., a subsidiary of Manulife Financial Corporation (MFC). Under the investment management contract, the Fund pays a daily management fee to the Adviser at an annual rate of 0.75% of the Fund’s average daily net asset value and the value attributable to the Auction Preferred Shares (collectively, managed assets).

The Adviser has agreed to limit the Fund’s management fee to the following: 0.55% of the Fund’s average daily managed assets until the fifth anniversary of the commencement of the Fund’s operations, 0.60% of such assets in the sixth year, 0.65% of such assets in the seventh year and 0.70% of average daily managed assets in the eighth year. Accordingly, the expense reductions related to the reduction in management fee amounted to $1,816,190 for the year ended July 31, 2007. After the eighth year the Adviser will no longer waive a portion of the management fee.

Effective December 31, 2005, the investment management teams of the Adviser were reorganized into Sovereign Asset Management LLC (Sovereign), a wholly owned indirect subsidiary of John Hancock Life Insurance Company (JHLICO), a subsidiary of MFC. The Adviser remains the principal advisor on the Fund and Sovereign acts as subadviser under the supervision of the Adviser. The restructuring did not have an impact on the Fund, which continues to be managed using the same investment philosophy and process. The Fund is not responsible for payment of the subadvisory fees.

Effective October 1, 2006 Sovereign changed its name to MFC Global Investment Management (U.S.), LLC.

The Fund has an agreement with the Adviser and affiliates to perform necessary tax, accounting and legal services for the Fund. The compensation for the year amounted to $113,006. The Fund also reimbursed JHLICO for certain compliance costs, included in the Fund’s Statement of Operations.

The Adviser and other subsidiaries of JHLICO owned 6,409 shares of beneficial interest of the Fund on July 31, 2007.

Mr. James R. Boyle is Chairman of the Adviser, as well as affiliated Trustee of the Fund, and is compensated by the Adviser and/or its affiliates. The compensation of unaffiliated Trustees is borne by the Fund. The unaffiliated Trustees may elect to defer, for tax purposes, their receipt of this compensation under the John Hancock Group of Funds Deferred Compensation Plan. The Fund makes investments into other John Hancock funds, as applicable, to cover its liability for the deferred compensation. Investments to cover the Fund’s deferred compensation liability are recorded on the Fund’s books as an other asset. The deferred compensation liability and the related other asset are always equal and are marked to market on a periodic basis to reflect any income earned by the investments, as well as any unrealized gains or losses. The Deferred Compensation Plan investments had no impact on the operations of the Fund.

The Fund is listed for trading on the NYSE and has filed with the NYSE its chief executive officer certification regarding compliance with the NYSE’s listing standards. The Fund also files with the Securities and Exchange Commission the certification of its chief financial officer and chief accounting officer required by Section 302 of the Sarbanes-Oxley Act.

Note 3
Guarantees and indemnifications

Under the Fund’s organizational documents, its Officers and Trustees are indemnified against certain liability 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. However, based on experience, the Fund believes the risk of loss to be remote.

Auction preferred shares

The Fund issued a total of 11,200 Auction Preferred Shares (2,240 shares of Series M, 2,240 shares of Series T, 2,240 shares of Series W, 2,240 shares of Series TH and 2,240 shares of Series F) (collectively, the APS) on October 23, 2002, in a public offering. The underwriting discount of $2,800,000 has been charged to capital paid-in of common shares during the period ended July 31, 2003. Offering costs of $617,673 related to common shares and offering costs of $385,442 incurred in connection with the preferred shares were charged to the Fund’s capital paid-in during the period ended July 31, 2003.

Dividends on the APS, which accrue daily, are cumulative at a rate that was established at the offering of the APS and has been reset every seven days thereafter by an auction. Prior to April 19, 2006, the rates on Series W had been reset and paid over special dividend payment periods. During the year ended July 31, 2007, dividend rates on APS ranged as follows: Series M from 4.84% to 5.32%, Series T from 4.75% to 5.32%, Series W from 4.20% to 5.30%, Series TH from 3.68% to 5.26% and Series F from 4.88% to 5.32% . Accrued dividends on APS are included in the value of APS on the Fund’s Statement of Assets and Liabilities.

The APS are redeemable at the option of the Fund, at a redemption price equal to $25,000 per share, plus accumulated and unpaid dividends on any dividend payment date. The APS are also subject to mandatory redemption at a redemption price equal to $25,000 per share, plus accumulated and unpaid dividends, if the Fund is in default on its asset coverage requirements with respect to the APS, as defined in the Fund’s bylaws. Under the 1940 Act, the Fund is required to maintain asset coverage of at least 200% with respect to the APS as of the last business day of each month in which the shares are outstanding. If the dividends on the APS shall remain unpaid in an amount equal to two full years’ dividends, the holders of the APS, as a class, have the right to elect a majority of the Board of Trustees. In general, the holders of the APS and the common shareholders have equal voting rights of one vote per share, except that the holders of the APS, as a class, vote to elect two members of the Board of Trustees, and separate class votes are required on certain matters that affect the respective interests of the APS and common shareholders.

Leverage

The Fund issued preferred shares to increase its assets available for investment. The Fund generally will not issue preferred shares unless the Adviser expects that the Fund will achieve a greater return on the proceeds resulting from the use of leverage than the additional costs the Fund incurs as a result of leverage. When the Fund leverages its assets, the fees paid to the Adviser for investment advisory and administrative services will be higher than if the Fund did not borrow because the Adviser’s fees are calculated based on the Fund’s total assets, including the proceeds of the issuance of preferred shares. Consequently, the Fund and the Adviser may have differing interests in determining whether to leverage the Fund’s

Preferred Income Fund

20


assets. The Board of Trustees will monitor this potential conflict. The Fund’s use of leverage is premised upon the expectation that the Fund’s dividends on its outstanding preferred shares will be lower than the return the Fund achieves on its investments with the proceeds of the issuance of preferred shares.

Leverage creates risks which 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 dividend rates on any preferred shares

• increased operations costs, which may reduce the Fund’s total return to the holders of common shares

• increased operating costs, which may reduce the Fund’s total return to the holders of common shares

• the potential for a decline in the value of an investment acquired through leverage, while the Fund’s obligations under such leverage remains fixed

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.

Note 5
Investment transactions

Purchases and proceeds from sales or maturities of securities, other than short-term securities and obligations of the U.S. government, during the year ended July 31, 2007, aggregated $132,210,410 and $134,879,410, respectively.

The cost of investments owned on July 31, 2007, including short-term investments, for federal income tax purposes was $902,839,354. Gross unrealized appreciation and depreciation of investments aggregated $16,034,078 and $44,092,696, respectively, resulting in net unrealized depreciation of $28,058,618. The difference between book basis and tax basis net unrealized depreciation of investments is attributable primarily to the tax deferral of losses on certain sales of securities and amortization of premiums and accretion of discounts on debt securities.

Note 6
Reclassification of accounts

During the year ended July 31, 2007, the Fund reclassified amounts to reflect a decrease in accumulated net realized gain on investments of $5,954,675, an increase in accumulated net investment income of $6,370,093 and a decrease in capital paid-in of $415,418. This represents the amounts necessary to report these balances on a tax basis, excluding certain temporary differences, as of July 31, 2007. Additional adjustments may be needed in subsequent reporting periods. These reclassifications, which have no impact on the net asset value of the Fund, are primarily attributable to certain differences in the computation of distributable income and capital gains under federal tax rules versus accounting principles generally accepted in the United States of America, book and tax differences in accounting for amortization of premium, federal excise tax, swaps, real estate investment trust distributions and non-deductible organizational costs. The calculation of net investment income per share in the Fund’s Financial Highlights excludes these adjustments.

Auditor’s report

Report of Independent Registered Public Accounting Firm


To the Board of Trustees and Shareholders of John Hancock Preferred Income Fund,

In our opinion, the accompanying statement of assets and liabilities, including the schedule of investments, and the related statements of operations and of changes in net assets and the financial highlights present fairly, in all material respects, the financial position of John Hancock Preferred Income Fund (the Fund) at July 31, 2007, the results of its operations for the year then ended, and the changes in its net assets and the financial highlights for each of the two years in the period then ended, in conformity with accounting principles generally accepted in the United States of America. These financial statements and financial highlights (hereafter referred to as “financial statements”) are the responsibility of the Fund’s management; our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits, which included confirmation of securities at July 31, 2007 by correspondence with the custodian and brokers, provide a reasonable basis for our opinion. The financial highlights for each of the periods ended on or before July 31, 2005 were audited by other auditors whose report expressed an unqualified opinion thereon.

Tax information

Unaudited


For federal income tax purposes, the following information is furnished with respect to the distributions of the Fund, if any, paid during its taxable year ended July 31, 2007.

The Fund has designated distributions to shareholders of $3,360,268 as long-term capital gain dividend.

With respect to the ordinary dividends paid by the Fund for the fiscal year ended July 31, 2007, 42.03% of the dividends qualifies for the corporate dividends-received deduction.

The Fund hereby designates the maximum amount allowable of its net taxable income as qualified dividend income as provided in the Jobs and Growth Tax Relief Reconciliation Act of 2003. This amount will be reflected on Form 1099-DIV for the calendar year 2007.

Shareholders will be mailed a 2007 U.S. Treasury Department Form 1099-DIV in January 2008. This will reflect the total of all distributions that are taxable for calendar year 2007.

Investment objective and policy

The Fund’s primary objective is 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. The Fund seeks to achieve its objectives by investing in a diversified portfolio of securities that, in the opinion of the Adviser, may be undervalued relative to similar securities in the marketplace.

Under normal market conditions, the Fund invests at least: (a) 80% of its assets in preferred stocks and other preferred securities, including convertible preferred securities, (b) 25% of its total assets in the industries comprising the utilities sector and (c) 80% of its total assets in preferred securities or other fixed-income securities, that are rated investment grade or higher by Moody’s or Standard & Poor’s at the time of investment. “Assets” are defined as net assets, including the liquidation preference of APS, plus borrowing for investment purposes.

Bylaws

On December 16, 2003, the Trustees approved the following change to the Fund’s bylaws. The auction preferred shares section of the Fund’s bylaws was changed to update the rating agency requirements in keeping with recent changes to the agencies’ basic maintenance reporting requirements for leveraged closed-end funds. Bylaws now require an independent accountants’ confirmation only once per year, at the Fund’s fiscal year end, and changes to the agencies’ basic maintenance reporting requirements that include modifications to the eligible assets and their respective discount factors. These revisions bring the Fund’s bylaws in line with current rating agency requirements.

On September 14, 2004, the Trustees approved an amendment to the Fund’s bylaws increasing the maximum applicable dividend rate ceiling on the preferred shares to conform with the modern calculation methodology used by the industry and other John Hancock funds.

Dividends and distributions

During the year ended July 31, 2007, dividends from net investment income totaling $1.8600 per share and distributions from capital gains totaling $0.2116 per share were paid to shareholders. The dates of payments and the amounts per share are as follows:

Dividend reinvestment plan

The Fund offers its shareholders a Dividend Reinvestment Plan (the Plan), which offers the opportunity to earn compounded yields. Each holder of common shares will automatically have all distributions of dividends and capital gains reinvested by Mellon Investor Services, as Plan Agent for the common shareholders (the Plan Agent), unless an election is made to receive cash. Holders of common shares who elect not to participate in the Plan will receive all distributions in cash, paid by check and mailed directly to the shareholder of record (or, if the common shares are held in street or other nominee name, then to the nominee) by the Plan Agent, as dividend-disbursing agent. Shareholders whose shares are held in the name of a broker or a nominee should contact the broker or nominee to determine whether and how they may participate in the Plan.

If the Fund declares a dividend payable either in common shares or in cash, non-participants will receive cash and participants in the Plan will receive the equivalent in common shares. If the market price of the common shares on the payment date of the dividend is equal to, or exceeds, their net asset value as determined on the payment date, participants will be issued common shares (out of authorized but unissued shares) at a value equal to the higher of net asset value or 95% of the market price. If the net asset value exceeds the market price of the common

24


shares at such time, or if the Board of Trustees declares a dividend payable only in cash, the Plan Agent will, as agent for Plan participants, buy shares in the open market, on the New York Stock Exchange or elsewhere, for the participants’ accounts. Such purchases will be made promptly after the payable date for such dividend and, in any event, prior to the next ex-dividend date after such date, except where necessary to comply with federal securities laws. If, before the Plan Agent has completed its purchases, the market price exceeds the net asset value of the common shares, the average per share purchase price paid by the Plan Agent may exceed the net asset value of the common shares, resulting in the acquisition of fewer shares than if the dividend had been paid in shares issued by the Fund.

Each participant will pay a pro rata share of brokerage commissions incurred with respect to the Plan Agent’s open market purchases in connection with the reinvestment of dividends and distributions. The cost per share of the shares purchased for each participant’s account will be the average cost, including brokerage commissions, of any shares purchased on the open market, plus the cost of any shares issued by the Fund. There will be no brokerage charges with respect to common shares issued directly by the Fund. There are no other charges to participants for reinvesting dividends or capital gain distributions.

Participants in the Plan may withdraw from the Plan at any time by contacting the Plan Agent by telephone, in writing or by visiting the Plan Agent’s Web site at www.melloninvestor.com. Such withdrawal will be effective immediately if received not less than 10 days prior to a dividend record date; otherwise, it will be effective for all subsequent dividend record dates. When a participant withdraws from the Plan or upon termination of the Plan, as provided below, certificates for whole common shares credited to his or her account under the Plan will be issued, and a cash payment will be made for any fraction of a share credited to such account.

The Plan Agent maintains each shareholder’s account in the Plan and furnishes monthly written confirmations of all transactions in the accounts, including information needed by the shareholders for personal and tax records. The Plan Agent will hold common shares in the account of each Plan participant in non-certificated form in the name of the participant. Proxy material relating to the shareholders’ meetings of the Fund will include those shares purchased, as well as shares held pursuant to the Plan.

The reinvestment of dividends and distributions will not relieve participants of any federal income tax that may be payable or required to be withheld on such dividends or distributions. Participants under the Plan will receive tax information annually. The amount of dividends to be reported on the 1099-DIV should be: (1) in the case of shares issued by the Fund, the fair market value of such shares on the dividend payment date and (2) in the case of shares purchased by the Plan Agent in the open market, the amount of cash used by the Plan Agent to purchase shares in the open market, including the amount of cash allocated to brokerage commissions paid on such purchases.

Experience under the Plan may indicate that changes are desirable. Accordingly, the Fund reserves the right to amend or terminate the Plan as applied to any dividend or distribution paid subsequent to written notice of the change sent to all shareholders of the Fund at least 90 days before the record date for the dividend or distribution. The Plan may be amended or terminated by the Plan Agent after at least 90 days’ written notice to all shareholders of the Fund. All correspondence or additional information concerning the Plan should be directed to the Plan Agent, Mellon Bank, N.A., c/o Mellon Investor Services, P.O. Box 3338, South Hackensack, NJ 07606-1938 (Telephone: 1-800-852-0218).

Board Consideration of and Continuation
of Investment Advisory Agreement and
Subadvisory Agreement: John Hancock
Preferred Income Fund

The Investment Company Act of 1940 (the 1940 Act) requires the Board of Trustees (the Board) of John Hancock Preferred Income Fund (the Fund), including a majority of the Trustees who have no direct or indirect interest in the investment advisory agreement and are not “interested persons” of the Fund, as defined in the 1940 Act (the Independent Trustees), annually to meet in person to review and consider the continuation of: (i) the investment advisory agreement (the Advisory Agreement) with John Hancock Advisers, LLC (the Adviser) and (ii) the investment subadvisory agreement (the Subadvisory Agreement) with MFC Global Investment Management (U.S.), LLC (the Subadviser). The Advisory Agreement and the Subadvisory Agreement are collectively referred to as the Advisory Agreements.

At meetings held on May 7 and June 4–5, 2007, the Board considered the factors and reached the conclusions described below relating to the selection of the Adviser and Subadviser and the continuation of the Advisory Agreements. During such meetings, the Board’s Contracts/ Operations Committee and the Independent Trustees also met in executive sessions with their independent legal counsel.

In evaluating the Advisory Agreements, the Board, including the Contracts/Operations Committee and the Independent Trustees, reviewed a broad range of information requested for this purpose by the Independent Trustees, including: (i) the investment performance of the Fund and a peer group of comparable funds (the Peer Group) selected by Morningstar, Inc. (Morningstar), an independent provider of investment company data, for a range of periods ended December 31, 2006,1 (ii) advisory and other fees incurred by, and the expense ratios of, the Fund relative to a Peer Group, (iii) the Adviser’s financial results and condition, including its and certain of its affiliates’ profitability from services performed for the Fund, (iv) breakpoints in the Fund’s and the Peer Group’s fees and information about economies of scale, (v) the Adviser’s and Subadviser’s record of compliance with applicable laws and regulations, with the Fund’s investment policies and restrictions, and with the applicable Code of Ethics, and the structure and responsibilities of the Adviser’s and Subadviser’s compliance department, (vi) the background and experience of senior management and investment professionals, and (vii) the nature, cost and character of advisory and non-investment management services provided by the Adviser and its affiliates and by the Subadviser.

The Independent Trustees considered the legal advice of independent legal counsel and relied on their own business judgment in determining the factors to be considered in evaluating the materials that were presented to them and the weight to be given to each such factor. The Board’s review and conclusions were based on a comprehensive consideration of all information presented to the Board and not the result of any single controlling factor. They principally considered performance and other information from Morningstar as of December 31, 2006. The Board also considered updated performance information provided to it by the Adviser or Subadviser at the May and June 2007 meetings. Performance and other information may be quite different as of the date of this shareholders report. The key factors considered by the Board and the conclusions reached are described below.

Nature, extent and quality of services

The Board considered the ability of the Adviser and the Subadviser, based on their resources, reputation and other attributes, to attract and retain qualified investment professionals, including research, advisory and supervisory personnel. The Board considered the investment philosophy, research and investment decision-making processes of the Adviser and Subadviser. The Board further considered the culture of compliance, resources dedicated to compliance, compliance programs and compliance records of the Adviser and Subadviser. In addition, the Board took into account the administrative and other non-advisory services provided to the Fund by the Adviser and its affiliates.

Based on the above factors, together with those referenced below, the Board concluded that,

27


within the context of its full deliberations, the nature, extent and quality of the investment advisory services provided to the Fund by the Adviser and Subadviser supported renewal of the Advisory Agreements.

Fund performance

The Board considered the performance results for the Fund over various time periods ended December 31, 2006. The Board also considered these results in comparison to the performance of the Peer Group, as well as the Fund’s benchmark index. Morningstar determined the Peer Group for the Fund. The Board reviewed with a representative of Morningstar the methodology used by Morningstar to select the funds in the Peer Group. The Board noted the imperfect comparability of the Peer Group and that Morningstar was not able to select a comparative Category for the Fund.

The Board recognized the relatively short operational history of the Fund and noted that the Fund’s performance during the three- and one-year periods was higher than the performance of the median of the Peer Group and its benchmark indices, the Merrill Lynch Preferred Stock Hybrid Securities Index and Lehman Brothers Aggregate Bond.

Investment advisory fee and subadvisory fee rates and expenses

The Board reviewed and considered the contractual investment advisory fee rate payable by the Fund to the Adviser for investment advisory services (the Advisory Agreement Rate). The Board received and considered information comparing the Advisory Agreement Rate with the advisory fees for the Peer Group. The Board noted that the Advisory Agreement Rate was lower than the median rate of the Peer Group.

The Board received and considered expense information regarding the Fund’s various components, including advisory fees, and other non-advisory fees, including administrative fees, transfer agent fees, custodian fees and other miscellaneous fees (e.g., fees for accounting and legal services). The Board considered comparisons of these expenses to the Peer Group median. The Board also received and considered expense information regarding the Fund’s total operating expense ratio (Gross Expense Ratio) and total operating expense ratio after taking the fee waiver arrangement applicable to the Advisory Agreement Rate into account (Net Expense Ratio). The Board received and considered information comparing the Gross Expense Ratio and Net Expense Ratio of the Fund to that of the Peer Group. The Board noted that the Fund’s Gross and Net Expense Ratios were lower than the median of the Peer Group.

The Adviser also discussed the Morningstar data and rankings, and other relevant information, for the Fund. Based on the above-referenced considerations and other factors, the Board concluded that the Fund’s overall performance and expenses supported the re-approval of the Advisory Agreements.

The Board also received information about the investment subadvisory fee rate (the Subadvisory Agreement Rate) payable by the Adviser to the Subadviser for investment sub-advisory services. The Board concluded that the Subadvisory Agreement Rate was fair and equitable, based on its consideration of the factors described here.

Profitability

The Board received and considered a detailed profitability analysis of the Adviser based on the Advisory Agreements, as well as on other relationships between the Fund and the Adviser and its affiliates, including the Subadviser. The Board concluded that, in light of the costs of providing investment management and other services to the Fund, the profits and other ancillary benefits reported by the Adviser were not unreasonable.

Economies of scale

The Board received and considered general information regarding economies of scale with respect to the management of the Fund, including the Fund’s ability to appropriately benefit from economies of scale under the Fund’s fee structure. The Board recognized the inherent limitations of any analysis of economies of scale, stemming largely from the Board’s understanding that most of the Adviser’s and Subadviser’s costs are not specific to individual Funds, but rather are incurred across a variety of products and services.

28


The Board observed that the Advisory Agreements did not offer breakpoints. However, the Board considered the limited relevance of economies of scale in the context of a closed-end fund that, unlike an open-end fund, does not continuously offer its shares. The Board noted that the Fund, as a closed-end investment company, was not expected to increase materially in size and that its assets would grow (if at all) through the investment performance of the Fund. Therefore, the Board did not consider potential economies of scale as a principal factor in assessing the fees payable under the Advisory Agreements, but concluded that the fees were fair and equitable based on relevant factors.

Other benefits to the Adviser

The Board received information regarding potential “fall-out” or ancillary benefits received by the Adviser and its affiliates as a result of the Adviser’s relationship with the Fund. Such benefits could include, among others, benefits directly attributable to the relationship of the Adviser with the Fund and benefits potentially derived from an increase in the business of the Adviser as a result of its relationship with the Fund (such as the ability to market to shareholders other financial products offered by the Adviser and its affiliates).

The Board also considered the effectiveness of the Adviser’s, Subadviser’s and Fund’s policies and procedures for complying with the requirements of the federal securities laws, including those relating to best execution of portfolio transactions and brokerage allocation.

Other factors and broader review

As discussed above, the Board reviewed detailed materials received from the Adviser and Subadviser as part of the annual re-approval process. The Board also regularly reviews and assesses the quality of the services that the Fund receives throughout the year. In this regard, the Board reviews reports of the Adviser and Subadviser at least quarterly, which include, among other things, fund performance reports and compliance reports. In addition, the Board meets with portfolio managers and senior investment officers at various times throughout the year.

After considering the above-described factors and based on its deliberations and its evaluation of the information described above, the Board concluded that approval of the continuation of the Advisory Agreements for the Fund was in the best interest of the Fund and its shareholders. Accordingly, the Board unanimously approved the continuation of the Advisory Agreements.

1 Morningstar also provided a comparative analysis for most, but not all, of the John Hancock Funds of the investment performance and advisory and other fees incurred by, and the expense ratios of, the John Hancock Funds relative to a category of relevant funds (the Category). Morningstar was not able to select a comparative Category for the John Hancock Preferred Income Fund. Therefore, Morningstar did not provide such an analysis.

Other Accounts the Portfolio Managers are Managing

The table below indicates, for each portfolio manager, information about the accounts over which the portfolio manager has day-to-day investment responsibility. All information on the number of accounts and total assets in the table is as of July 31, 2007. For purposes of the table, “Other Pooled Investment Vehicles” may include investment partnerships and group trusts, and “Other Accounts” may include separate accounts for institutions or individuals, insurance company general or separate accounts, pension funds and other similar institutional accounts.

P O R T F O L I O   M A N A G E R  O T H E R   A C C O U N T S   M A N A G E D   B Y   T H E   P O R T F O L I O   M A N A G E R S 

 
Gregory K. Phelps  Other Registered Investment Companies: 5 (five) funds 
  with total assets of approximately $4.2 billion 
  Other Pooled Investment Vehicles: None 
  Other Accounts: None 
 
Mark T. Maloney  Other Registered Investment Companies: 5 (five) funds 
  with total assets of approximately $4.2 billion 
  Other Pooled Investment Vehicles: None 
  Other Accounts: None 

The Adviser does not receive a fee based upon the investment performance of any of the accounts included under “Other Accounts Managed by the Portfolio Managers” in the table above.

When a portfolio manager is responsible for the management of more than one account, the potential arises for the portfolio manager to favor one account over another. For the reasons outlined below, the Fund does not believe that any material conflicts are likely to arise out of a portfolio manager’s responsibility for the management of the Fund as well as one or more other accounts. The Adviser and the Subadviser have adopted procedures, overseen by the Chief Compliance Officer, that are intended to monitor compliance with the policies referred to in the following paragraphs.

30


• The Subadviser has policies that require a portfolio manager to allocate investment opportunities in an equitable manner and generally to allocate such investments proportionately among all accounts with similar investment objectives.

• When a portfolio manager intends to trade the same security for more than one account, the policies of the Subadviser generally require that such trades for the individual accounts are aggregated so that each account receives the same price. When not possible or when it may not result in the best possible price, the Subadviser will place the order in a manner intended to result in as favorable a price as possible for such client.

• The investment performance on specific accounts is not a factor in determining the portfolio manager’s compensation. See “Compensation of Portfolio Managers” below. Neither the Adviser nor the Subadviser receives a performance-based fee with respect to other accounts managed by the Fund’s portfolio managers.

• The Subadviser imposes certain trading restrictions and reporting requirements for accounts in which a portfolio manager or certain family members have a personal interest in order to confirm that such accounts are not favored over other accounts.

• The Subadviser seeks to avoid portfolio manager assignments with potentially conflicting situations. However, where a portfolio manager is responsible for accounts with differing investment objectives and policies, it is possible that the portfolio manager will conclude that it is in the best interest of one account to sell a portfolio security while another account continues to hold or increase the holding in such security.

Compensation of Portfolio Managers

The Subadviser has adopted a system of compensation for portfolio managers and others involved in the investment process that is applied consistently among investment professionals. At the Subadviser, the structure of compensation of investment professionals is currently composed of the following basic components: fixed base salary, and an annual investment bonus plan, as well as customary benefits that are offered generally to all full-time employees of the Subadviser. A limited number of senior portfolio managers, who serve as officers of both the Subadviser and its parent company, may also receive options or restricted stock grants of common shares of Manulife Financial Corporation.

Only investment professionals are eligible to participate in the Investment Bonus Plan on an annual basis. While the amount of any bonus is discretionary, the following factors are generally used in determining bonuses: 1) The investment performance of all accounts managed by the investment professional over one- and three-year periods are considered. The pre-tax performance of each account is measured relative to an appropriate peer group benchmark. 2) The profitability of the Subadviser and its parent company are also considered in determining bonus awards, with greater emphasis placed upon the profitability of the Adviser. 3) The more intangible contributions of an investment professional to the Subadviser’s business, including the investment professional’s support of sales activities, new fund/strategy idea generation, professional growth and development, and management, where applicable, are evaluated in determining the amount of any bonus award.

While the profitability of the Subadviser and the investment performance of the accounts that the investment professionals maintain are factors in determining an investment professional’s overall compensation, the investment professional’s compensation is not linked directly to the net asset value of any fund.

These fees were billed to the registrant and were approved by the registrant’s audit committee.

(b) Audit-Related Services

There were no audit-related fees during the fiscal year ended July 31, 2007 and fiscal year ended July 31, 2006 billed to the registrant or to the registrant's investment adviser (not including any sub-adviser whose role is primarily portfolio management and is subcontracted with or overseen by another investment adviser), and any entity controlling, controlled by, or under common control with the adviser that provides ongoing services to the registrant ("control affiliates").

(c) Tax Fees

The aggregate fees billed for professional services rendered by the principal accountant(s) for the tax compliance, tax advice and tax planning (“tax fees”) amounted to $3,700 for the fiscal year ended July 31, 2007 and $3,700 for the fiscal year ended July 31, 2006. The nature of the services comprising the tax fees was the review of the registrant’s income tax returns and tax distribution requirements. These fees were billed to the registrant and were approved by the registrant’s audit committee. There were no tax fees billed to the control affiliates.

(d) All Other Fees

The all other fees billed to the registrant for products and services provided by the principal accountant were $3,000 for the fiscal year ended July 31, 2007 and $3,000 for the fiscal year ended July 31, 2006. There were no other fees during the fiscal year ended July 31, 2007 and July 31, 2006 billed to control affiliates for products and services provided by the principal accountant.

(f) According to the registrant’s principal accountant, for the fiscal year ended July 31, 2007, the percentage of hours spent on the audit of the registrant's financial statements for the most recent fiscal year that were attributed to work performed by persons who were not full-time, permanent employees of principal accountant was less than 50%.

The Adviser does not receive a fee based upon the investment performance of any of the accounts included under “Other Accounts Managed by the Portfolio Managers” in the table above.

When a portfolio manager is responsible for the management of more than one account, the potential arises for the portfolio manager to favor one account over another. For the reasons outlined below, the Fund does not believe that any material conflicts are likely to arise out of a portfolio manager’s responsibility for the management of the Fund as well as one or more other accounts. The Adviser and the Subadviser have adopted procedures, overseen by the Chief Compliance Officer, that are intended to monitor compliance with the policies referred to in the following paragraphs.

• The Subadviser has policies that require a portfolio manager to allocate investment opportunities in an equitable manner and generally to allocate such investments proportionately among all accounts with similar investment objectives.

• When a portfolio manager intends to trade the same security for more than one account, the policies of the Subadviser generally require that such trades for the individual accounts are aggregated so that each account receives the same price. When not possible or when it may not result in the best possible price, the Subadviser will place the order in a manner intended to result in as favorable a price as possible for such client.

• The investment performance on specific accounts is not a factor in determining the portfolio manager’s compensation. See “Compensation of Portfolio Managers” below. Neither the Adviser nor the Subadviser receives a performance-based fee with respect to other accounts managed by the Fund’s portfolio managers.

• The Subadviser imposes certain trading restrictions and reporting requirements for accounts in which a portfolio manager or certain family members have a personal interest in order to confirm that such accounts are not favored over other accounts.

• The Subadviser seeks to avoid portfolio manager assignments with potentially conflicting situations. However, where a portfolio manager is responsible for accounts with differing investment objectives and policies, it is possible that the portfolio manager will conclude that it is in the best interest of one account to sell a portfolio security while another account continues to hold or increase the holding in such security.

Compensation of Portfolio Managers

The Subadviser has adopted a system of compensation for portfolio managers and others involved in the investment process that is applied consistently among investment professionals. At the Subadviser, the structure of compensation of investment professionals is currently composed of the following basic components: fixed base salary, and an annual investment bonus plan, as well as customary benefits that are offered generally to all full-time employees of the Subadviser. A limited number of senior portfolio managers, who serve as officers of both the Subadviser and its parent company, may also receive options or restricted stock grants of common shares of Manulife Financial Corporation.

Only investment professionals are eligible to participate in the Investment Bonus Plan on an annual basis. While the amount of any bonus is discretionary, the following factors are generally used in determining bonuses: 1) The investment performance of all accounts managed by the investment professional over one- and three-year periods are considered. The pre-tax performance of each account is measured relative to an appropriate peer group benchmark. 2) The profitability of the Subadviser and its parent company are also considered in determining bonus awards, with greater emphasis placed upon the profitability of the Adviser. 3) The more intangible contributions of an investment professional to the Subadviser’s business, including the investment professional’s support of sales activities, new fund/strategy idea generation, professional growth and development, and management, where applicable, are evaluated in determining the amount of any bonus award.

While the profitability of the Subadviser and the investment performance of the accounts that the investment professionals maintain are factors in determining an investment professional’s overall compensation, the investment professional’s compensation is not linked directly to the net asset value of any fund.
