Shepherdson to pursue other opportunities. In addition, on July 25, 2005, your fund's Board of Trustees appointed me to the roles of President and Chief Executive Officer of your fund. As a means of introduction, I have been involved in the mutual fund industry since 1985. I have been with John Hancock Funds for the last 15 years, most recently as executive vice president of retail sales and marketing and a member of the company's executive and investment committees. In my former capacity, I was responsible for all aspects of the distribution and marketing of John Hancock Funds' open-end and closed-end mutual funds. Outside of John Hancock, I have served as Chairman of the Investment Company Institute (ICI) Sales Force Marketing Committee since September 2003. It is an exciting time to be at John Hancock Funds, and I am grateful for the opportunity to lead and shape its future growth. With the acquisition of John Hancock by Manulife Financial Corporation in April 2004, we are receiving broad support toward the goal of providing our shareholders with excellent investment opportunities and a more complete lineup of choices for the discerning investor. As you may have read, John Hancock recently entered into an agreement with GMO, a Boston-based institutional money manager, to acquire eight of their mutual funds. In addition, we are in the process of adding five "Lifestyle Portfolio" funds-of-funds that blend multiple fund offerings from internal and external money managers to create a broadly diversified asset allocation portfolio. Look for more information about these exciting additions to the John Hancock family of funds in your fourth quarter shareholder newsletter. Although there has been a change in executive-level management, rest assured that the one thing that never wavers is John Hancock Funds' commitment to placing the needs of shareholders above all else. We are all dedicated to the task of working with you and your financial advisors to help you reach your long-term financial goals. Sincerely, /S/ Keith F. Hartstein Keith F. Hartstein, President and Chief Executive Officer This commentary reflects the CEO's views as of June 30, 2005. They are subject to change at any time. YOUR FUND AT A GLANCE The Fund seeks to provide a high level of after-tax total return from divi- dend income and capital appreciation. To meet its objec- tives, the Fund normally invests at least 80% of its assets in dividend- paying common and preferred securities that the Adviser believes are eligible to pay dividends that qualify for U.S. taxation rates applicable to long- term capital gains, which currently are taxed at a maximum rate of 15%. Over the last six months * Dividend-paying securities posted good gains, fueled by strong investor demand. * Utility common stocks and preferred stocks performed best, driven in part by strong demand for high-quality and high income-producing investments. * Financial stocks were lackluster, dogged by rising interest rates.

PHELPS, JAMES K. SCHMIDT, CFA, MARK T. MALONEY, AND LISA A. WELCH FOR THE PORTFOLIO MANAGEMENT TEAM MANAGERS' REPORT JOHN HANCOCK Tax-Advantaged Dividend Income Fund Dividend-paying securities posted strong gains for the six-month period ended June 30, 2005. Utility common stocks were the clear victors during the past six months, and ended the period as one of the overall stock market's best-performing industry groups. There was robust investor demand for utility common stocks due to their high dividend payouts, which were very attractive in a period when fixed-income investments offered investors low interest rates. Additionally, investors became increasingly bullish on the group in response to utility companies' strides to reduce their debt levels and improve their balanced sheets. Utility commons really surged in the final month of the period, due to the announcement of planned mergers of several large well-known players, which fueled speculation that more merger and acquisition activity was on the horizon. Preferred stocks also benefited from strong demand from yield-hungry investors seeking refuge from the overall stock market's lackluster returns and volatility. Financial stocks significantly lagged utility common stocks and preferred stocks, primarily due to the rising interest rate environment and by a flattening yield curve, as short-term rates rose faster than those at the longer end. "Dividend-paying securities posted strong gains for the six-month period ended June 30, 2005." Performance For the six months ended June 30, 2005, John Hancock Tax-Advantaged Dividend Income Fund returned 6.34% at net asset value and 4.47% at market value. The difference in the Fund's net asset value (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. Over the same six-month period, the Standard & Poor's 500 Index returned --0.81% and the average closed-end value fund returned 3.06% at net asset value, according to Lipper, Inc. 2 Chart-topping utility common stocks Given the sector's overall strength, it's not surprising that many of the Fund's utility common stock holdings were our best performers during the year. Among the best was NSTAR, which transmits and delivers electricity to customers in eastern and central Massachusetts. It was also powered by company-specific developments, including the settlement of a contentious strike, the company's effecting a two-for-one stock split and continued financial improvement. Other chart toppers were Cinergy Corp., which performed well throughout the year and then got an added kick from the news that Duke Energy would acquire the company, and Scottish Power, which was boosted on a planned acquisition of the company's largest subsidiary by Berkshire Hathaway. Public Service Enterprise Group did well in response to expectations that its planned acquisition by Exelon would proceed fairly quickly. Utility companies with oil and gas operations also fared well as the price of energy skyrocketed, with holdings such as Black Hills Corp., National Fuel Gas and ONEOK Inc. each posting impressive stock price gains. [Photos of Greg Phelps, Jim Schmidt, Mark Maloney and Lisa Welch, flush right at top of page.] Preferred-stock holdings: leaders and laggards Among our preferred-stock holdings, Monongahela Power Co., a subsidiary of utility holding company Alleghany Energy, was one of our top performers. It benefited from improving financial results, prompting a major ratings agency to upgrade Monongahela's credit rating. On the flip side were our holdings in Lehman Brothers, which tread water during the period because they carried yields below that offered by newly issued securities, which muted demand for the securities. "...many of the Fund's utility com mon stock holdings also were our best performers during the year." Financials: mixed bag Banks with limited exposure to the mortgage business and better commercial loan growth performed relatively well for the period, including Colonial BancGroup and Whitney Holding Corp. The detractors typically were companies that had earnings disappointments or lowered guidance on future earnings, such as JPMorgan Chase & Co. 3 Supply glut = opportunity In the final months of the period, there was a glut of newly issued preferred stocks, as companies rushed to lock in low interest rates. That influx of supply temporarily weighed on preferred-stock prices and afforded us the opportunity to buy some attractively valued tax-advantaged issues with relatively high coupons. Among our purchases was Entergy Mississippi, an electric utility company with an improving credit profile and insurance giant MetLife, which carried coupons of 6.25% and 6.50%, respectively.

The chart is divided into three sections (from top to left): Common stocks 77%, Preferred stocks 22% and Short-term investments & other 1%.] Outlook After chalking up substantial gains over the past two years, the utilities sector has shown no signs of retreat. Utilities continue to reap the benefits of their efforts to repair their balance sheets, improve cash flows, whittle down debts and return to their core competencies by shedding non-regulated business. And with utilities looking to consolidate and cut costs, we believe that more merger and acquisition activity is likely, which we expect to provide a good underpinning for utility stocks. In addition, there is the strong possibility that unfavorable federal regulation that has dogged the industry may be repealed. Finally, there remains a strong appetite for dividends, with utility stocks being a primary beneficiary of that trend. 4 That said, given their strong recent gains, some moderation in utility stock performance is likely in the cards. Given our forecast for slowing economic conditions and ongoing strong demand for dividend-paying securities, we believe that preferred stocks may have the wind at their backs in the months to come. As for financial stocks, history shows that the performance of the group improves as we approach the end of an interest rate hike cycle. At the end of the period, financial stocks as a group were moderately undervalued on a price-to-book or price-earnings basis when compared to historic norms.

See notes to financial statements. 15 NOTES TO STATEMENTS Unaudited Note A Accounting policies John Hancock Tax-Advantaged Dividend 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 which have a remaining maturity of 60 days or less may be 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. 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. Selling futures tends to decrease the Fund's exposure to the underlying instrument or hedge other Fund's instruments. At the time the Fund enters into financial futures contracts, it is required to deposit with its custodian a specified amount of cash or U.S. government securities, known as "initial margin," equal to a certain percentage of the value of the financial futures contract being traded. 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 16 opening or realizing the benefits of closing out financial futures positions because of position limits or limits on daily price fluctuations 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 June 30, 2005, the Fund had deposited $247,500 in a segregated account to cover margin requirements on open financial futures contracts. The Fund had the following financial futures contracts open on June 30, 2005: NUMBER OF APPRECIATION/ OPEN CONTRACTS CONTRACTS POSITION EXPIRATION (DEPRECIATION) - ------------------------------------------------------------------------------- U.S. Treasury 10-year Note 300 Short Sep 05 ($647,493) U.S. Treasury 10-year Note 30 Short Sep 05 $15,728 ($631,765) 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, if any, on the ex-dividend date. During the year ended December 31, 2004, the tax character of distributions paid was as follows: ordinary income $40,984,036. 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 John Hancock Financial Services, Inc. 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 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. 17 Accordingly, the expense reductions related to the reduction in the management fee amounted to $1,220,648 for the period ended June 30, 2005. 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 amounted to $149,655. The Fund also paid the Adviser the amount of $16,453 for certain compliance costs, included in the miscellaneous expenses. 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 New York Stock Exchange ("NYSE") and has filed with the NYSE its chief executive officer certification regarding compliance with the NYSE's listing standards. The Funds also files with the Securities and Exchange Commission the certification of its chief executive officer and chief accounting officer required by Section 302 of the Sarbanes-Oxley Act. Note C Fund share transactions This listing illustrates the number of Fund common shares sold, offering costs and underwriting discount charged to capital paid-in and the number of common shares outstanding at the end of the period, along with the corresponding dollar value.

Unaudited. 3 Net of $0.90 per share sales load of the initial offering price of $20.00 per share. 18 Auction preferred shares The Fund issued a total of 15,200 Auction Preferred Shares (3,800 shares of Series M, 3,800 shares of Series W, 3,800 shares of Series TH and 3,800 shares of Series F) (collectively, the "APS") on May 3, 2004, in a public offering. The underwriting discount of $3,800,000 and offering costs of $396,310 incurred in connection with the preferred shares and offering costs of $854,726 related to common shares were charged to capital paid-in of common shares during the period ended December 31, 2004. 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 TH, which reset its rate on October 28, 2004, at which time the Fund elected a Special Dividend Payment of 182 days for the subsequent distributions). During the period ended June 30, 2005, dividend rates on APS ranged as follows: Series M from 2.25% to 3.22%, Series W from 2.19% to 3.30%, Series TH from 2.45% to 3.70% and Series F from 2.15% to 3.20%. 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 shareholders. Note D 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 period ended June 30, 2005, aggregated $208,351,585 and $211,881,201, respectively. The cost of investments owned on June 30, 2005, including short-term investments, for federal income tax purposes, was $1,176,748,136. Gross unrealized appreciation and depreciation of investments aggregated $91,229,305 and $13,457,634, respectively, resulting in net unrealized appreciation of $77,771,671. The difference between book basis and tax basis net unrealized appreciation of investments is attributable primarily to the tax deferral of losses on certain sales of securities. 19 Investment objective and policy The Fund's investment objective is to provide a high level of after-tax total return from dividend income and capital appreciation. Under normal market conditions, the Fund will invest at least 80% of its assets (net assets plus borrowings for investment purposes) in dividend-paying common and preferred securities that the Adviser believes at the time of acquisition are eligible to pay dividends which, for individual shareholders, qualify for U.S. federal income taxation at rates applicable to long-term capital gains, which currently are taxed at a maximum rate of 15% ("tax-advantaged dividends"). Tax-advantaged dividends generally include dividends from domestic corporations and dividends from foreign corporations that meet certain specified criteria. The Fund generally can pass the tax treatment of tax-advantaged dividends it receives through to its common shareholders. Dividends and distributions During the period ended June 30, 2005, dividends from net investment income totaling $0.5802 per share were paid to common shareholders. The dates of payments and the amounts per share are as follows: PAYMENT INCOME DATE DIVIDEND - -------------------------------------------- January 31, 2005 $0.0967 February 28, 2005 0.0967 March 31, 2005 0.0967 April 29, 2005 0.0967 May 31, 2005 0.0967 June 30, 2005 0.0967 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 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 20 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 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 pay ment 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 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). Shareholder communication and assistance If you have any questions concerning the Fund, we will be pleased to assist you. If you hold shares in your own name and not with a brokerage firm, please address all notices, correspondence, questions or other communications regarding the Fund to the transfer agent at: Mellon Investor Services 85 Challenger Road Overpeck Centre Ridgefield Park, NJ 07660 Telephone: 1-800-852-0218 If your shares are held with a brokerage firm, you should contact that firm, bank or other nominee for assistance. 21 Shareholder meeting On March 2, 2005, the Annual Meeting of the Fund was held to elect five Trustees and to ratify the actions of the Trustees in selecting independent auditors for the Fund.

At meetings held on May 19-20 and June 6-7, 2005, the Board, including the Independent Trustees considered the factors and reached the conclusions described below relating to the selection of the Adviser and the continuation of the Advisory Agreement. 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 Agreement, 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 but not limited to the following: (i) the investment performance of the Fund and a broader universe of relevant funds (the "Universe") selected by Lipper Inc. ("Lipper"), an independent provider of investment company data, for a range of periods, (ii) advisory and other fees incurred by, and the expense ratios of, the Fund and a peer group of comparable funds selected by Lipper (the "Peer Group"), (iii) the advisory fees of comparable portfolios of other clients of the Adviser, (iv) the Adviser's financial results and condition, including its and certain of its affiliates' profitability from services performed for the Fund, (v) breakpoints in the Fund's and the Peer Group's fees and a study undertaken at the direction of the Independent Trustees as to the allocation of the benefits of economies of scale between the Fund and the Adviser, (vi) the Adviser's record of compliance with applicable laws and regulations, with the Fund's investment policies and restrictions, and with the Fund's Code of Ethics and the structure and responsibilities of the Adviser's compliance department, (vii) the background and experience of senior management and investment professionals, and (viii) the nature, cost and character of advisory and non-investment management services provided by the Adviser and its affiliates. Nature, Extent and Quality of Services The Board considered the ability of the Adviser, based on its resources, reputation and other attributes, to attract and retain qualified investment professionals, including research, advisory, and supervisory personnel. The Board further considered the compliance programs and compliance records of the Adviser. In addition, the Board took into account the administrative 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, within the context of its full deliberations, the nature, extent and quality of the investment advisory services provided to the Fund by the Adviser were sufficient to support renewal of the Advisory Agreement. Fund Performance The Board noted that the Fund had less than one full year of operational history, and considered the performance results for the Fund since its inception through December 31, 2004. The Board also considered these 23 results in comparison to the performance of the Universe, as well as the Fund's benchmark index. Lipper determined the Universe for the Fund. The Board reviewed with a representative of Lipper the methodology used by Lipper to select the funds in the Universe and the Peer Group. The Board noted that the performance of the Fund was not appreciably below the median and average performance of its Universe for the time period under review. The Board also noted that the Fund performed lower than the Dow Jones Utility Average Index, the Fund's benchmark index, as did the Universe. The Board recognized the short operational history of the Fund and indicated its intent to continue to monitor the Fund's performance trends. Investment Advisory 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 noted the fee waiver arrangement applicable to the Advisory Agreement Rate and considered the Advisory Agreement Rate after taking the waivers into account (the "Net Advisory Rate"). The Board received and considered information comparing the Advisory Agreement Rate and Net Advisory Rate with the advisory fees for the Peer Group. The Board noted that the Advisory Agreement Rate and Net Advisory Rate were lower than the median rate of the Peer Group, and reasonable in relation to the services provided. The Board received and considered information regarding the Fund's total operating expense ratio and its various components, including contractual advisory fees, actual advisory fees, non-management fees, transfer agent fees and custodian fees, including and excluding investment-related expenses. The Board also considered comparisons of these expenses to the Peer Group and the Universe. The Board noted that the total operating expense ratio of the Fund was lower than the Peer Group's and Universe's median total operating expense ratio. The Adviser also discussed the Lipper 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 expense results and performance supported the re-approval of the Advisory Agreement. Profitability The Board received and considered a detailed profitability analysis of the Adviser based on the Advisory Agreement, as well as on other relationships between the Fund and the Adviser and its affiliates. 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 costs are not specific to individual Funds, but rather are incurred across a variety of products and services. The Board observed that the Advisory Agreement 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, and concluded that the fees were fair and equitable based on relevant factors, including the Fund's total expenses ranking relative to its Peer Group. 24 Information About Services to Other Clients The Board also received information about the nature, extent and quality of services and fee rates offered by the Adviser to its other clients, including other registered investment companies, institutional investors and separate accounts. The Board concluded that the Advisory Agreement Rate was not unreasonable, taking into account fee rates offered to others by the Adviser and giving effect to differences in services covered by such fee rates. 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 and the 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 as part of the annual re-approval process under Section 15(c) of the 1940 Act. 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 at least quarterly, which include, among other things, a detailed portfolio review, detailed 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 Agreement for the Fund was in the best interest of the Fund and its shareholders. Accordingly, the Board unanimously approved the continuation of the Advisory Agreement. 25 26 27 28 For more information The Fund's proxy voting policies, procedures and records are available without charge, upon request: By phone On the Fund's Web site On the SEC's Web site 1-800-225-5291 www.jhfunds.com/proxy www.sec.gov Trustees Charles L.

As of the end of the period, June 30, 2005, the registrant has adopted a code of ethics, as defined in Item 2 of Form N-CSR, that applies to its Chief Executive Officer, Chief Financial Officer and Treasurer (respectively, the principal executive officer, the principal financial officer and the principal accounting officer, the "Senior Financial Officers"). A copy of the code of ethics is filed as an exhibit to this Form N-CSR. The code of ethics was amended effective February 1, 2005 to address new Rule 204A-1 under the Investment Advisers Act of 1940 and to make other related changes. The most significant amendments were: (a) Broadening of the General Principles of the code to cover compliance with all federal securities laws. (b) Eliminating the interim requirements (since the first quarter of 2004) for access persons to preclear their personal trades of John Hancock mutual funds. This was replaced by post-trade reporting and a 30 day hold requirement for all employees.
