CEO corner

To Our Shareholders,

The U.S. financial markets turned in solid results over the last six months, as earlier concerns of rising inflation, a housing slowdown and high energy prices gave way to news of slower, but still resilient, economic growth, stronger than expected corporate earnings and dampened infla-tion fears and energy costs. This environment also led the Federal Reserve Board to hold short-term interest rates steady. Even with a sharp decline toward the end of the period, the broad stock market returned 7.38% for the six months ended March 31, 2007, as measured by the S&P 500 Index. With interest rates remaining relatively steady, fixed-income securities also produced positive results.

But after a remarkably long period of calm, the financial markets were rocked near the end of the period by a dramatic sell-off in China’s stock market, which had ripple effects on financial markets worldwide. In the United States, for example, the Dow Jones Industrial Average had its steepest one-day percentage decline in nearly four years on February 27, 2007. The event served to jog investors out of their seemingly casual attitude toward risk and remind them of the simple fact that stock markets move in two directions — down as well as up.

It was also a good occasion to bring to mind several important investment principles that we believe are at the foundation of successful investing. First, keep a long-term approach to investing, avoiding emotional reactions to daily market moves. Second, maintain a well-diversified portfolio that is appropriate for your goals, risk profile and time horizons.

After the market’s moves of the last six months, we encourage investors to sit back, take stock and set some realistic expectations. While history bodes well for the U.S. market in 2007 (since 1939, the S&P 500 Index has always produced positive results in the third year of a presidential term), there are no guarantees, and opinions are divided on the future of this more-than-four-year-old bull market. The recent downturn, which lasted for a month before positive news stopped the fall, bolsters this uncertainty, although we believe it was a healthy correction for which we were overdue.

The recent volatility could also be a wake-up call to contact your financial professional to determine whether changes are in order to your investment mix. Some asset groups have had long runs of outperformance. Others had truly outsized returns in 2006. These trends argue for a look to determine if these categories now represent a larger stake in your portfolios than prudent diversification would suggest they should. After all, we believe investors with a well-balanced portfolio and a marathon — not a sprint — approach to investing, stand a better chance of weathering the market’s short-term twists and turns, and reaching their long-term goals.

Sincerely,


Keith F. Hartstein, 
President and Chief Executive Officer

Managers’ report

John Hancock

Patriot Premium Dividend Fund I

Preferred stocks and utility common stocks — the two primary areas of emphasis for John Hancock Patriot Premium Dividend Fund I — posted strong gains for the six-month period ended March 31, 2007. Both got off to a strong start in the early months of the period when fixed-income investments performed well, bolstered by optimism that the Federal Reserve Board might cut interest rates in early 2007. Because preferreds and utility common stocks tend to make fixed-income payments in the form of dividends, their prices generally move higher and lower in response to expectations for interest rates and inflation. A series of reports indicating that the housing market and other parts of the economy were slowing provided investors evidence that infla-tion wasn’t the same concern it had been just a few months earlier.

Utility common stocks chalked up even stronger returns in the first three months of 2007, while preferred stocks posted decent gains. Both utility common and preferred stocks continued to be bolstered by persistently strong investor demand for securities that generated attractive amounts of incremental income over U.S. Treasury securities. Both asset classes also benefited from a reasonably favorable interest rate environment, as the Federal Reserve Board left its target short-term interest rate unchanged at 5.25% . They enjoyed a particularly good period in late February and early March when a significant plunge in Chinese stocks, which sparked world wide equity market declines, and growing worries

about problems in the subprime mortgage market, prompted investors to seek the relative safety of income-producing investments. A spate of merger and acquisition activity further boosted utility stocks, although preferreds retraced some of those gains late in the period as a growing supply of the securities acted as a drag on their prices.

“Perferred stocks and utility
common stocks …posted strong
gains for the six-month period
ended March 31, 2007.”

Performance

For the six months ended March 31, 2007, John Hancock Patriot Premium Dividend Fund I returned 9.47% at net asset value (NAV) and 8.56% 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. The Fund’s yield at closing market price on March 31, 2007 was 5.13% . By comparison, the average closed-end specialty-utilities fund returned 14.19% at NAV, according to Morningstar, Inc. For the same six-month period, the Lehman Brothers Aggregate Bond Index gained 2.76%, the Merrill Lynch Preferred Stock DRD Index rose 5.63% and the S&P 400 Mid-Cap Utilities Index returned 16.28% .

Common stock winners

Our utility common stock holdings provided the biggest boost to the Fund’s performance. Among the most significant contributors was National Fuel Gas Co. It performed well, thanks in large part to strong pricing conditions for natural gas and investors’ excitement over the company’s plans to explore for gas in the Devonian black shales region in Pennsylvania and New York. NiSource, Inc. also performed well, thanks in large part to investors’

upward revaluation of natural gas pipeline and storage assets. Peoples Energy — which sells and transports natural gas to residential, commercial and industrial customers in the Chicago area — also helped boost the Fund’s return in response to the company’s now-completed takeover by Wisconsin-based WPS Resources. Our holdings in telecommunications giant AT&T, Inc., also fared well due to growing recognition that the company’s stock provided an attractive dividend yield, that its merger was working and that it was gaining market share in the broadband and wireless segments.

Preferred stock leaders and laggards

Among our preferred holdings, we enjoyed strong performance from PNM Resources, Inc., helped by the company’s ability to generate higher-than-expected customer growth. In addition, investors were excited by news that Microsoft founder Bill Gates’ personal investment vehicle was entering into a joint venture with the utility and energy company. Our holdings in MetLife, Inc. also served us well, aided by strong demand for DRD-eligible preferreds. Bank of America Corp. preferred holdings also enjoyed solid performance, helped by investor demand for attractively priced tax-advantaged preferred stocks issued by high-quality companies amid a dearth of such securities.

Many of our preferred stock holdings in the brokerage area performed quite well during the six-month period, led by Goldman Sachs Group, Inc. and Merrill Lynch & Co., Inc. The brokers benefited from their ability to fire on all cylinders in their key businesses, including stocks, investment banking, asset management and private equity. They also benefited from providing services to the thriving hedge fund industry, as well as posting strong gains from their proprietary trading accounts.

In contrast, we lost ground with our stake in Ocean Spray Cranberries, Inc., an agricultural cooperative owned by more than 650 cranberry growers in Massachusetts, Wisconsin, New Jersey, Oregon, Washington, British Columbia and other parts of Canada, as well as more than 100 Florida grapefruit growers. Our holdings were part of a private placement, whereby the company sold securities to a relatively small number of institutional investors rather than to the public at large.

Despite this preferred stock’s sought-after tax-advantaged status, its prices languished as investors increasingly went for more liquid, meaning easily traded, securities. We continued to hold onto our Ocean Spray stake because we believe that this high-quality company has the potential to be taken over by a larger multinational food company at an attractive premium to the price we paid for it.

“Our utility common stock
holdings provided the biggest
boost to the Fund’s performance.”

Outlook

By the end of the period, Treasury bonds were priced such that investors were still expecting a rate cut in the second calendar quarter of this year. With inflation running at the upper end of the Fed’s stated comfort zone, we don’t believe the central bank will be so quick to stimulate the economy via rate cuts. Given that, we wouldn’t be surprised if Treasuries come under near-term pressure once investors come to grips with the fact that rate cuts are farther off then they may have originally anticipated. If Treasuries sell off, it’s likely that preferreds will follow suit over the near term. Over the longer term,  however, 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 utility common and preferred stocks.

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.

Notes to financial statements (unaudited)

Note 1 Accounting policies

John Hancock Patriot Premium Dividend Fund I (the “Fund”) is a diversified closed-end management investment company registered under the Investment Company Act of 1940 (the “1940 Act”), as amended.

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 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.

Expenses

The majority of the expenses are directly iden-tifiable 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 sizes of the funds.

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. For federal income tax purposes, the Fund has $7,244,165 of a capital loss carryforward available, to the extent provided by regulations, to offset future net realized capital gains. To the extent that such carryforward is used by the Fund, no capital gain distributions will be made. The loss carryforward expires September 30, 2014.

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 is currently evaluating the application of the Interpretation to the Fund and has not at this time quantified the impact, if any, resulting from the adoption of this Interpretation on the Fund’s financial statements. The Fund will implement this pronouncement no later than March 31, 2008.

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. The Fund may place a security on non-accrual status and reduce related investment income by ceasing current accruals or writing off interest, or dividends receivable, when the collection of income has become doubtful. 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 September 30, 2006, the tax character of distributions paid was as follows: ordinary income $10,612,693.

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 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 John Hancock Financial Services, Inc., a subsidiary of Manulife Financial Corporation (“MFC”). Under the investment management contract, the Fund pays a monthly management fee to the Adviser at an annual rate of 0.50% of the Fund’s average weekly net asset value attributable to the Dutch Auction Rate Transferable Securities preferred shares (collectively, “managed assets”), plus 5.00% of the Fund’s weekly gross income, $311,880 for the period ended March 31, 2007. The Adviser’s total fee is limited to a maximum amount equal to 1.00% annually of the Fund’s average weekly managed assets. For the period ended March 31, 2007, the advisory fee incurred did not exceed the maximum advisory fee allowed.

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 administrative agreement with the Adviser under which the Adviser oversees the custodial, auditing, valuation, accounting, legal, stock transfer and dividend disbursing services and maintains Fund communications with shareholders. The Fund pays the Adviser a monthly administration fee at an annual rate of 0.10% of the Fund’s average weekly managed assets. The compensation for the period amounted to $112,540. The Fund also reimbursed JHLICO for certain compliance costs, included in the Fund’s Statement of Operations.

Mr. James R. Boyle is Chairman of the Adviser, as well as an 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 unaf-filiated 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

Patriot Premium Dividend Fund I

16


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 certifica-tion regarding compliance with the NYSE’s listing standards. The Fund also files with the Securities and Exchange Commission the cer-tification of its chief executive officer and chief financial officer required by Section 302 of the Sarbanes-Oxley Act.

Dutch Auction Rate Transferable Securities preferred shares Series A

The Fund issued 685 shares of Dutch Auction Rate Transferable Securities preferred shares Series A (“DARTS”) in a public offering. The underwriting discount was recorded as a reduction of the capital of common shares.

Dividends on the DARTS, which accrue daily, are cumulative at a rate that was established at the offering of the DARTS and has been reset every 49 days thereafter by an auction. Dividend rates on DARTS ranged from 3.999% to 4.190% during the period ended March 31, 2007. Accrued dividends on DARTS are included in the value of DARTS on the Fund’s Statement of Assets and Liabilities.

The DARTS are redeemable at the option of the Fund, at a redemption price equal to $100,000 per share, plus accumulated and unpaid dividends on any dividend payment date. The DARTS are also subject to mandatory redemption at a redemption price equal to $100,000 per share, plus accumulated and unpaid dividends, if the Fund is in default on its asset coverage requirements with respect to the DARTS, as defined in the Fund’s bylaws. If the dividends on the DARTS shall remain unpaid in an amount equal to two full years’ dividends, the holders of the DARTS, as a class, have the right to elect a majority of the Board of Trustees. In general, the holders of the DARTS and the common shareholders have equal voting rights of one vote per share, except that the holders of the DARTS, 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 DARTS 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

Patriot Premium Dividend Fund I

17


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

• 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 4
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 March 31, 2007, aggregated $6,362,288 and $5,029,005, respectively.

The cost of investments owned on March 31, 2007, including short-term investments, for federal income tax purposes was $204,578,717. Gross unrealized appreciation and depreciation of investments aggregated $26,595,465 and $2,381,048, respectively, resulting in net unrealized appreciation of $24,214,417. 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.

Note 5
Supplemental event

On April 23, 2007, the shareholders approved the merger of the Fund into John Hancock Patriot Premium Dividend Fund II, effective June 25, 2007.

Investment objective and policy

The Fund’s investment objective is to provide a high current income consistent with modest growth of capital for holders of its common shares of beneficial interest. The Fund will pursue its objective by investing in a diversified portfolio of dividend-paying preferred and common stocks.

The Fund’s non-fundamental investment policy with respect to the quality of ratings of its portfolio investments, which was changed by a vote of the Fund’s Trustees on September 13, 1994, and became effective October 15, 1994, stipulates that preferred stocks and debt obligations in which the Fund will invest will be rated investment grade (at least “BBB” by S&P or “Baa” by Moody’s) at the time of investment or will be preferred stocks of issuers of investment-grade senior debt, some of which may have speculative characteristics or, if not rated, will be of comparable quality as determined by the Adviser. The Fund will invest in common stocks of issuers whose senior debt is rated investment-grade or, in the case of issuers that have no rated senior debt outstanding, whose senior debt is considered by the Adviser to be of comparable quality.

This revised policy supersedes the requirement that at least 80% of the Fund’s total assets consist of preferred stocks and debt obligations rated “A” or higher and dividend-paying common stocks whose issuers have senior debt rated “A” or higher.

On November 20, 2001, the Fund’s Trustees approved the following investment policy investment restriction change, effective December 15, 2001. Under normal circumstances, the Fund will invest at least 80% of its assets in dividend-paying securities. The “Assets” are defined as net assets, including the liquidation preference amount of the DARTS, plus borrowings for investment purposes. The Fund will notify shareholders at least 60 days prior to any change in this 80% investment policy.

By-laws

In November 2002, the Board of Trustees adopted several amendments to the Fund’s by-laws, including provisions relating to the calling of a special meeting and requiring advance notice of shareholder proposals or nominees for Trustee. The advance notice provisions in the by-laws require shareholders to notify the Fund in writing of any proposal that they intend to present at an annual meeting of shareholders, including any nominations for Trustee, between 90 and 120 days prior to the first anniversary of the mailing date of the notice from the prior year’s annual meeting of shareholders. The notification must be in the form prescribed by the by-laws. The advance notice provisions provide the Fund and its Trustees with the opportunity to thoughtfully consider and address the matters proposed before the Fund prepares and mails its proxy statement to shareholders. Other amendments set forth the procedures that must be followed in order for a shareholder to call a special meeting of shareholders. Please contact the Secretary of the Fund for additional information about the advance notice requirements or the other amendments to the by-laws.

On December 16, 2003, the Trustees approved the following change to the Fund’s by-laws. The auction preferred 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. By-laws now require an independent accountant’s 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 by-laws in line with current rating agency requirements.

On September 14, 2004, the Trustees approved an amendment to the Fund’s by-laws 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 period ended March 31, 2007, dividends from net investment income totaling

Patriot Premium Dividend Fund I

19


$0.234 per share were paid to shareholders. The dates of payments and the amounts per share are as follows:

  INCOME

October 31, 2006  $0.039

February 28, 2007  0.039 
March 30, 2007  0.039 

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.

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 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-certifi-cated form in the name of the participant. Proxy material relating to the shareholders’ meetings of

Patriot Premium Dividend Fund I

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).

Board Consideration of and
Continuation of Investment Advisory
Agreement and Subadvisory
Agreement: John Hancock Patriot
Premium Dividend Fund I

The Investment Company Act of 1940 (the “1940 Act”) requires the Board of Trustees (the “Board”) of John Hancock Patriot Premium Dividend Fund I (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 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 subadvi-sory agreement (the “Subadvisory Agreement”) with Sovereign Asset Management LLC (the “Subadviser”). The Advisory Agreement and the Subadvisory Agreement are collectively referred to as the “Advisory Agreements.”

At meetings held on May 1–2 and June 5–6, 2006,1 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, 2005;2 (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 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. It was based on performance and other information as of December 31, 2005; facts may have changed between that date and 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 further considered the compliance programs and compliance records of the Adviser and Subadviser. 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 and Subadviser were sufficient to support renewal of the Advisory Agreements.

Fund performance

The Board considered the performance results for the Fund over various time periods ended December 31, 2005. The Board also considered these results in comparison to the performance of the Peer Group, as well as the

22


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 noted that the Fund’s performance during the 5-year period was lower than the performance of the median of the Peer Group and its benchmark index, the Merrill Lynch Preferred Stock DRD Eligible Index. The Board also noted that Fund’s more recent performance during the 1- and 3-year periods was either higher than or not appreciably lower than the performance of the Peer Group median, and its benchmark index.

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 (“Expense Ratio”). The Board received and considered information comparing the Expense Ratio of the Fund to that of the Peer Group median. The Board noted that the Fund’s Expense Ratio was higher than the Peer Group median.

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 plans for improving overall performance and lowering the Expense Ratio 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 subadvisory 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.

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

23


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 The Board previously considered information about the Subadvisory Agreement at the September and December 2005 Board meetings in connection with the Adviser’s reorganization.
2 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 Patriot Premium Dividend Fund I. Therefore, Morningstar did not provide such an analysis.
