The threat of war with Iraq increased and terrorism fears grew. The uncertainty surrounding these and other geopolitical issues became uppermost in investors' minds and caused the market to continue the tumble that marked 2002. In the month of January, the Dow Jones Industrial Average returned -3.24%, the Standard & Poor's 500 Index lost 2.61% and the Nasdaq Composite Index lost 1.09%. Bonds remained essentially flat in January, with the exception of lower-grade high-yield bonds, which continued a rally they began in the fourth quarter of 2002. January's results matched the trend of the last three years, in which stocks lost ground every year as the economy stalled, corporate spending and profits were lackluster and investor confidence plunged amid corporate scandals. Bonds, on the other hand, outperformed stocks for a third straight year and produced positive results in 2002, while 96% of U.S. diversified stock mutual funds lost money. These results only confirm the importance of having a portfolio well-diversified among stocks, bonds and cash. In fact, the disparity between stock and bond results over the last three years means that many investors' portfolios may have shifted substantially in their mix between stocks and bonds. We recommend working with your investment professional to rebalance your assets according to your long-term goals. After three down years, no one can predict when the bear market cycle will turn. Currently, uncertainties abound, with ongoing concerns about the economy and the possibility of war and other geopolitical risks. While all these factors are beyond our control, investors can take charge of how they maneuver through the inevitable bull and bear market cycles. We've said it before, but it bears repeating: the key is to keep a long-term perspective and work with your investment professional to develop and maintain a properly diversified portfolio. We believe this offers the best protection in tough times and the best means to reach your long-term goals. Sincerely, /S/ MAUREEN R. FORD Maureen R. Ford, Chairman 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 portfo- lio of securities that, in the opin- ion of the Adviser, may be underval- ued relative to similar securities in the marketplace. Under normal mar- ket conditions, the Fund invests at least 80% of assets in preferred stocks and other pre- ferred securities. Over the last six months * Preferred stocks performed relatively well, driven by falling interest rates and strong demand. * Since the Fund's inception in August 2002, the investment team has been assembling a diversified portfolio of stocks offering value and strong fundamentals. * Oil and natural gas-related holdings performed best as prices of both commodities soared.

EVANS, CFA, FOR THE PORTFOLIO MANAGEMENT TEAM John Hancock Preferred Income Fund From the inception of John Hancock Preferred Income Fund on August 27, 2002, through January 31, 2003, preferred stocks turned in relatively good performances compared to U.S. common stocks. Much of preferred stocks' gains were driven by falling interest rates, which continued to drift lower in late summer and early fall 2002 in response to a weak economy. That trend continued throughout the remainder of the period, fueled by a surprise half percentage point rate cut by the Federal Reserve Board in November. Preferred stocks pay dividends, just like bonds pay regular interest, and, like bonds, their prices tend to rise when interest rates fall. "...preferred stocks turned in relatively good perfor mances compared to U.S. common stocks." Another factor helping the preferred-stock market was strengthening demand from income-seeking investors looking for significantly higher yields than what companies were paying on their bonds and common stocks. Many preferred stocks continued to yield between 7% and 9%, outstripping by a fairly wide margin the yields paid by corporate and other bonds and the dividends paid by common stocks. Demand further strengthened in December and January when a number of newly launched mutual funds focusing on preferred stocks began to invest their assets. In the final month of the period, the preferred market got an added boost from President Bush's proposal to eliminate the double taxation of dividends. Even though most of the preferred stocks that the Fund focuses on won't enjoy tax relief from this proposal, since their dividends are paid in pre-tax dollars, their prices were lifted by the development. FUND PERFORMANCE From its inception on August 27, 2002 through January 31, 2003, John Hancock Preferred Income Fund returned 2.22% at net asset value. Over the same period, the Standard & Poor's 500 Index returned -7.74% and the average income and preferred stock closed-end fund returned 0.56%. [Photos of Greg Phelps, Mark Maloney and Barry Evans flush right next to first paragraph.] OUR INVESTMENT PROCESS Our investment philosophy is a fairly straightforward, time-tested process guided by our experienced team of portfolio managers and security analysts. The Fund's primary objective is to provide a high level of current income consistent with preservation of capital. We seek to produce superior results by focusing on the business cycle and individual security fundamentals. This focus on fundamentals means we don't just chase yield. High yield often suggests additional risk -- particularly a heightened sensitivity to interest-rate changes or lower credit quality. We prefer to avoid making bets on the direction of interest rates by altering the Fund's interest-rate sensitivity, and we keep a minimum of 80% of the Fund's investments in investment-grade preferred stocks and bonds. In structuring the portfolio, we seek to add investment value in two ways. First, we try to anticipate broader, more gradual changes in the business cycle, and then invest in those industries and sectors that are expected to benefit from the changes. Second, we look within those industries and sectors for issuers and companies that are undervalued and mispriced relative to the market overall. "...we have found some of the best combinations of value and good fundamen- tals primarily in the utility, financial services and oil and gas industry groups..." DIVERSIFICATION IS KEY We also put a premium on diversifying the portfolio among a number of industry groups. Since the Fund began operations, we have found some of the best combinations of value and good fundamentals primarily in the utility, financial services and oil and gas industry groups. Among utilities, we favored domestic, regionally based utility companies that have little or no unregulated operations. One of our larger holdings in this area at the end of the period was Dominion Resources. We like the company because of its large, core base of regulated gas and electric utility operations, its major natural gas pipeline operations and its very profitable oil and natural gas production capabilities. Among financial institutions, we emphasized large domestic money center banks and large broker service companies such ING Groep, an international financial services company with a strong track record of successfully entering new markets. [Table at top left-hand side of page entitled "Top five industry groups 1." The first listing is Utilities 55%, the second is Banks--United States 8%, the third Finance 6%, the fourth Oil & gas 5%, and the fifth REITs 3%.] [Pie chart in middle of page with heading "Portfolio diversification 1" The chart is divided into four sections (from top to left): Common stocks 3%, Preferred stocks 88%, Corporate bonds 2% and Short-term investments & other 7%.] LEADERS AND LAGGARDS As for oil and gas producers, our favorite and one of our best performers during the period was Nexen, Inc., a Canadian oil and natural gas production company with significant international oil production. The run-up in oil prices -- which also helped pump up natural gas prices -- caused companies involved in the production and distribution of oil and natural gas to be among our best performers in the period. Despite relatively anemic global demand for energy, oil and natural gas prices skyrocketed as the year wore on, due to growing concerns about the oil strike in Venezuela and a possible U.S. attack on Iraq that may disrupt oil supplies. [Table at top of page entitled "SCORECARD." The header for the left column is "INVESTMENT" and the header for the right column is "RECENT PERFORMANCE...AND WHAT'S BEHIND THE NUMBERS." The first listing is Nexen, Inc. followed by an up arrow with the phrase "Oil prices spike amid fears of Iraq war." The second listing is Energy East followed by an up arrow with the phrase "Demand for high-yielding stocks boosts price." The third listing is El Paso Tennessee Pipeline followed by a down arrow with the phrase "Company's role in California power crisis questioned."] On the flip side was El Paso Corp. and its wholly owned subsidiary Coastal. Those holdings came under pressure when a judge ruled that the company had manipulated pipeline capacity during the 2001 California power crisis. We think the company will be exonerated in its appeal to the Federal Energy Regulatory Commission. "Low interest rates should continue to prompt strong demand for preferred stocks..." OUTLOOK Our view is that continued lackluster economic growth will preclude the need for interest rate hikes for the foreseeable future. Low interest rates should continue to prompt strong demand for preferred stocks from all types of investors seeking alternatives to low-yielding money market investments and higher-yielding, but more risky, types of taxable bonds. Another factor likely to ignite demand is President Bush's proposal to eliminate taxes on some dividends. In the weeks following that announcement, many investors started to put higher values on many dividend-producing stocks. This commentary reflects the views of the portfolio management team through the end of the Fund's period discussed in this report. Of course, the team's views are subject to change as market and other conditions warrant. 1 As a percentage of the Fund's portfolio on 1-31-03.

See notes to financial statements. NOTES TO STATEMENTS Unaudited NOTE A 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. Significant accounting policies of the Fund are as follows: Valuation of investments Securities in the Fund's portfolio are valued on the basis of market quotations, valuations provided by independent pricing services or at fair value as determined in good faith in accordance with procedures approved by the Trustees. Short-term debt investments maturing within 60 days are valued at amortized cost, which approximates market value. The Fund determines the net asset value of the common shares each business day. Investment transactions Investment transactions are recorded as of the date of purchase, sale or maturity. Net realized gains and losses on sales of investments are determined on the identified cost basis. Discount and premium on securities The Fund accretes discount and amortizes 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 the expenses are directly identifiable to an individual fund. Expenses that are not readily identifiable to a specific fund will be allocated in such a manner as deemed equitable, taking into consideration, among other things, the nature and type of expense and the relative sizes of the funds. Organization expenses and offering costs Expenses incurred in connection with the organization of the Fund, which amounted to $53,000, have been borne by the Fund. Offering costs of $819,000 related to common shares and offering costs of $482,000 incurred in connection with the preferred shares were charged to the Fund's common shares capital paid-in. 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. 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 to shareholders from net investment income and net realized gains on the ex-dividend date. Such distributions, 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 B 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 Berkeley Financial Group, LLC. Under the investment management contract, the Fund pays a monthly management fee to the Adviser at an annual rate of 0.75% of the Fund's average daily net assets and the value attributable to the Auction Preferred Shares ("managed assets"). The Adviser has contractually 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 reduction in the management fee amounted to $656,422 for the period ended January 31, 2003. After the eighth year the Adviser will no longer waive a portion of the management fee. The Fund has an agreement with the Adviser to perform necessary tax, accounting and legal services for the Fund. The compensation for the period was at an annual rate of approximately 0.03% of the average managed assets of the Fund. Ms. Maureen R. Ford and Mr. John M. DeCiccio are directors and/or officers of the Adviser and/or its affiliates, as well as Trustees of the Fund. 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 investment as well as any unrealized gains or losses. The Deferred Compensation Plan investments had no impact on the operations of the Fund.

Unaudited. 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 of 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. 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 7 days thereafter by an auction (except for the Series W, for which the initial reset date will be April 23, 2003). Dividend rates on APS ranged from 1.25% to 1.95% during the period ended January 31, 2003. 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 by-laws. 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 shares. NOTE D Investment transactions Purchases and proceeds from sales of securities, other than short-term securities and obligations of the U.S. government, during the period ended January 31, 2003, aggregated $2,296,050,877 and $52,574,620, respectively. The cost of investments owned on January 31, 2003, including short-term investments, for federal income tax purposes was $896,970,734. Gross unrealized appreciation and depreciation of investments aggregated $15,859,708 and $18,972,470, respectively, resulting in net unrealized depreciation of $3,112,762. 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 which 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. 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 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 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 participant's 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, except for certain brokerage commissions, as described above. 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 ten 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 dividend to be reported on 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). SHAREHOLDER COMMUNICATION AND ASSISTANCE If you have any questions concerning the Fund, we will be pleased to assist you.
