(2) PAST PERFORMANCE IS NO GUARANTEE OF FUTURE RESULTS. Total return is determined by subtracting the initial investment from the redeemable value at the end of the period and dividing the remainder by the initial investment and expressing the result as a percentage. The calculation assumes that all income dividends have been reinvested at prices obtained under the Fund's dividend reinvestment plan. Total investment return does not reflect broker commissions or sales charges. Total return for a period of less than one year is not annualized. An investment in the Fund involves risk, including the loss of principal. Investment return, price, yield and net asset value will fluctuate with changes in market conditions. This data is provided for information only and is not intended for trading purposes. Closed-end funds, unlike open-end funds, are not continuously offered. There is a one-time public offering and once issued, shares of closed-end funds are sold in the open market through a stock exchange. Net asset value is total assets applicable to common shareholders less total liabilities divided by the number of common shares outstanding. Holdings are subject to change daily. (3) Market Price Yield is determined by dividing the annualized current monthly per share dividend to common shareholders by the market price per common share at November 30, 2003. 2 PIMCO CORPORATE OPPORTUNITY FUND SCHEDULE OF INVESTMENTS November 30, 2003 PRINCIPAL AMOUNT CREDIT RATING (000) (MOODY'S/S&P)* VALUE** LONG-TERM INVESTMENTS--89.7% CORPORATE BONDS & NOTES - 77.0% AIRLINES - 5.3% Continental Airlines, Inc., pass thru certificates, $ 4,656 6.703%, 6/15/21, Ser. 01-1 Baa3/A- $ 4,649,980 3,500 7.373%, 12/15/15, Ser. 01-1 Ba1/BBB 2,990,579 2,000 7.487%, 10/2/10, Ser. 00-2 Baa3/A 2,019,141 10,584 7.707%, 4/2/21, Ser. 00-2 Baa3/A- 10,684,969 Delta Airlines, Inc., pass thru certificates, 13,484 7.57%, 11/18/10, Ser. 00-1 Baa2/A 13,899,144 12,000 7.92%, 11/18/10, Ser. 00-1 Baa3/BBB 10,813,112 Northwest Airlines Corp., pass thru certificates, 1,681 6.81%, 2/1/20, Ser. 991A Baa3/BBB- 1,494,609 14,250 6.841%, 4/1/11, Ser. 01-1 Baa3/A 13,967,518 5,737 7.575%, 3/1/19, Ser. 992A Baa2/A+ 5,909,474 United Airlines, Inc., pass thru certificates, 15,411 7.186%, 4/1/11, Ser. 00-2 Ba3/BBB- 13,134,355 10,000 7.73%, 7/1/10, Ser. 00-1 Ba3/BBB- 8,212,338 --------------- 87,775,219 =============== AUTOMOTIVE - 3.2% 4,000 Auburn Hills Trust, 12.375%, 5/1/20 A3/BBB 5,746,820 8,000 DaimlerChrysler Holdings Co., 1.94%, 9/26/05 (a) A3/BBB 8,005,144 21,000 Ford Motor Co., 7.45%-9.98%, 7/16/31-2/15/47 Baa1/BBB- 21,169,362 15,000 General Motors Corp., 8.375%-9.40%, 7/15/21-7/5/33 Baa1/BBB 18,288,364 --------------- 53,209,690 =============== BANKING - 1.3% 1,000 HSBC Capital Funding LP., 4.61%, 12/13/49 (acquired 6/24/03; cost-$1,000,000) (b) (c) A2/A- 942,813 9,706 Riggs Capital Trust II, 8.875%, 3/15/27, Ser.

ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES PIMCO Corporate Opportunity Fund (the "Fund"), was organized as a Massachusetts business trust on September 13, 2002. Prior to commencing operations on December 27, 2002, the Fund had no operations other than matters relating to its organization and registration as a diversified, closed-end management investment company registered under the Investment Company Act of 1940 and the rules and regulations thereunder, as amended, and the sale and issuance of 6,981 shares of beneficial interest at an aggregate purchase price of $100,003 to Allianz Dresdner Asset Management of America L.P. ("ADAM"). PIMCO Advisors Fund Management LLC (the "Investment Manager"), serves as the Fund's Investment Manager and is an indirect wholly-owned subsidiary of ADAM. ADAM is an indirect, majority-owned subsidiary of Allianz AG. The Fund has an unlimited amount of $0.0001 par value common stock authorized. The Fund seeks to maximize total return through a combination of current income and capital appreciation in a diversified portfolio of U.S. dollar denominated corporate debt obligations of varying maturities and other income producing securities. The Fund issued 55,500,000 shares of common stock, in its initial public offering. An additional 7,730,000 shares were issued in connection with the exercise of the underwriters' over-allotment option. These shares were all issued at $15.00 per share before an underwriting discount of $0.675 per share. Common offering costs of $1,541,506 (representing $0.024 per share) were offset against the proceeds of the offering and have been charged to paid-in capital in excess of par. The Investment Manager agreed to pay all offering costs (other than the sales load) and organizational expenses exceeding $0.03 per share. Since aggregate offering costs and organizational expenses were less than $0.03 per common share, organizational expenses of $15,000 were expensed in the current period. In addition, the underwriters' commission and offering costs associated with the issuance of Preferred Shares in the amounts of $5,650,000 and $554,930, respectively, have been charged to paid-in capital in excess of par. The preparation of the financial statements in accordance with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts and disclosures in the financial statements. Actual results could differ from these estimates. In the normal course of business the Fund enters into contracts that contain a variety of representations which provide general indemnifications. The Fund's maximum exposure under these arrangements is unknown as this would involve future claims that may be made against the Fund that have not yet been asserted. However, the Fund expects the risk of any loss to be remote. The following is a summary of significant accounting policies followed by the Fund: (a) VALUATION OF INVESTMENTS Portfolio securities and other financial instruments for which market quotations are readily available are stated at market value. Debt securities are valued daily by an independent pricing service approved by the Board of Trustees. Prices may be obtained from independent pricing services which use information provided by market makers or estimates of market values obtained from yield data relating to investments or securities with similar characteristics. The value of the Fund's investments is determined at the close of regular trading (normally, 4:00 p.m., Eastern Time) on the New York Stock Exchange ("NYSE") on each day the NYSE is open or if no sales are reported, as is the case for most securities traded over-the-counter, the mean between representative bid and asked quotations obtained from a quotation reporting system or from established market makers. Fixed income securities, including those to be purchased under firm commitment agreements, are normally valued on the basis of quotes obtained from brokers and dealers or pricing services. Short-term investments maturing in 60 days or less are valued at amortized cost, which approximates market value. Certain fixed income securities for which daily market quotations are not readily available may be valued, pursuant to guidelines established by the Board of Trustees, with reference to fixed income securities whose prices are more readily obtainable. The prices used by the Fund to value securities may differ from the value that would be realized if the securities were sold. (b) INVESTMENT TRANSACTIONS AND INVESTMENT INCOME Investment transactions are accounted for on the trade date. Securities purchased or sold on a when-issued or delayed delivery basis may be settled a month or more after trade date. Realized gains and losses on investments are determined on the identified cost basis. Interest income is recorded on an accrual basis. Discounts or premiums on debt securities purchased are accreted or amortized to interest income over the lives of the respective securities using the effective interest method. (c) FEDERAL INCOME TAXES The Fund intends to distribute all of its taxable income and to comply with the other requirements of the U.S. Internal Revenue Code of 1986, as amended, applicable to regulated investment companies. Accordingly, no provision for U.S. federal income taxes is required. In addition, by distributing substantially all of its ordinary income and long-term capital gains, if any, during each calendar year the Fund intends not to be subject to U.S. federal excise tax. Under 13 certain circumstances, however, the Fund may determine to retain a portion of its taxable income, if such retention is deemed to be in the interest of the Fund and its shareholders. In such a circumstance, the Fund may be subject to a 4% excise tax. (d) DIVIDENDS AND DISTRIBUTIONS -- COMMON STOCK The Fund declares dividends from net investment income monthly to common shareholders. Distributions of net realized capital gains, if any, are paid at least annually. The Fund records dividends and distributions to its shareholders on the ex-dividend date. The amount of dividends and distributions from net investment income and net realized capital gains are determined in accordance with federal income tax regulations, which may differ from generally accepted accounting principles. These "book-tax" differences are either considered temporary or permanent in nature. To the extent these differences are permanent in nature, such amounts are reclassified within the capital accounts based on their income tax treatment; temporary differences do not require reclassification. To the extent dividends and/or distributions exceed current and accumulated earnings and profits for federal income tax purposes, they are reported as dividends and/or distributions of paid-in capital in excess of par. (e) CREDIT DEFAULT/INTEREST RATE SWAPS The Fund enters into interest rate and credit default swap contracts ("swaps") for investment purposes, to manage its interest rate and credit risk or to add leverage. As a seller in the credit default swap contract, the Fund would be required to pay the par or other agreed-upon value of a referenced debt obligation to the counterparty in the event of a default by a third party, such as a U.S. or foreign corporate issuer, on the referenced debt obligation. In return, the Fund would receive from the counterparty a periodic stream of payments over the term of the contract provided that no event of default has occurred. If no default occurs, the Fund would keep the stream of payments and would have no payment obligations. Such periodic payments are accrued daily and recorded as interest income. The Fund may also purchase credit default swap contracts in order to hedge against the risk of default of debt securities held, in which case the Fund would function as the counterparty referenced in the preceding paragraph. As a purchaser of a credit default swap contract, the Fund would receive the par or other agreed upon value of a referenced debt obligation from the counterparty in the event of default by a third party, such as a U.S. or foreign corporate issuer on the referenced debt obligation. In return, the Fund would make periodic payments to the counterparty over the term of the contract provided no event of default has occurred. Such periodic payments are accrued daily and charged to interest income. Interest rate swap agreements involve the exchange by the Fund with a counterparty of their respective commitments to pay or receive interest, e.g., an exchange of floating rate payments for fixed rate payments with respect to a notional amount of principal. Net payments of interest on interest rate swap agreements are recorded daily as interest income. Swaps are marked to market daily by the Fund's Investment Manager based upon quotations from market makers and the change in value, if any, is recorded as unrealized appreciation or depreciation in the Fund's Statement of Operations. Payments received or made, if any, upon termination or maturity of the interest rate swaps, net of any basis in the interest rate swaps, is recorded as a realized gain or loss in the Statement of Operations. For a credit default swap sold by the Fund, payment of the agreed upon amount made by the Fund in the event of default of the referenced debt obligation is recorded as the cost of the referenced debt obligation purchased/received. For a credit default swap purchased by the Fund, the agreed upon amount received by the Fund in the event of default of the referenced debt obligation is recorded as proceeds from sale/delivery of the referenced debt obligation and the resulting gain or loss realized on the referenced debt obligation is recorded as such by the Fund. Entering into swaps involves, to varying degrees, elements of credit, market and documentation risk in excess of the amounts recognized on the Statement of Assets and Liabilities. Such risks involve the possibility that there will be no liquid market for these agreements, that the counterparty to the agreements may default on its obligation to perform or disagree as to the meaning of the contractual terms in the agreements, and that there may be unfavorable changes in net interest rates. (f) REPURCHASE AGREEMENTS The Fund may enter into transactions with its custodian bank or securities brokerage firms approved by the Board of Trustees whereby it purchases securities under agreements to resell at an agreed upon price and date ("repurchase agreements"). Such agreements are carried at the contract amount in the financial statements. Collateral pledged (the securities received), which consists primarily of U.S. government obligations and asset backed securities, are held by 14 the custodian bank until maturity of the repurchase agreement. Provisions of the repurchase agreements and the procedures adopted by the Fund require that the market value of the collateral, including accrued interest thereon, is sufficient in the event of default by the counterparty. If the counterparty defaults and the value of the collateral declines or if the counterparty enters an insolvency proceeding, realization of the collateral by the Fund may be delayed or limited. (g) FORWARD FOREIGN CURRENCY CONTRACTS The Fund may enter into forward foreign currency contracts for the purpose of hedging against foreign currency risk arising from the investment or anticipated investment in securities denominated in foreign currencies. The Fund may also enter into these contracts for purposes of increasing exposure to a foreign currency or to shift exposure to foreign currency fluctuations from one country to another. A forward foreign currency contract is an agreement between two parties to buy and sell a currency at a set exchange rate on a future date. The market value of a forward foreign currency contract fluctuates with changes in forward currency exchange rates. All commitments are marked to market daily at the applicable exchange rates and any resulting unrealized gains and losses are recorded. Realized gains or losses are recorded at the time the forward contract matures or by delivery of the currency. Risks may arise upon entering these contracts from the potential inability of counterparties to meet the terms of their contracts and from unanticipated movements in the value of a foreign currency relative to the U.S. dollar. (h) OPTION TRANSACTIONS For hedging purposes, the Fund may purchase and write (sell) put and call options. The risk associated with purchasing an option is that the Fund pays a premium whether or not the option is exercised. Additionally, the Fund bears the risk of loss of premium and change in market value should the counterparty not perform under the contract. Put and call options purchased are accounted for in the same manner as portfolio securities. The cost of securities acquired through the exercise of call options is increased by the premiums paid. The proceeds from the securities sold through the exercise of put options is decreased by the premiums paid. When an option is written, the premium received is recorded as an asset with an equal liability which is subsequently adjusted to the current market value of the option written. Premiums received from writing options which expire unexercised are recorded on the expiration date as a realized gain. The difference between the premium received and the amount paid on effecting a closing purchase transaction, including brokerage commissions, is also treated as a realized gain, or if the premium is less than the amount paid for the closing purchase transactions, as a realized loss. If a call option is exercised, the premium is added to the proceeds from the sale of the underlying security in determining whether there has been a realized gain or loss. If a put option is exercised, the premium reduces the cost basis of the security. In writing an option, the Fund bears the market risk of an unfavorable change in the price of the security underlying the written option. Exercise of an written option could result in the Fund purchasing a security at a price different from the current market. (i) LOAN PARTICIPATIONS The Fund may invest in loan participations. When the Fund purchases a loan participation, the Fund typically enters into a contractual relationship with the lender or third party selling such participations ("Selling Participant"), but not the borrower. As a result, the Fund assumes the credit risk of the borrower, the Selling Participant and any other persons interpositioned between the Fund and the borrower. The Fund may not directly benefit from the collateral supporting the senior loan in which it has purchased the loan participation. (j) FUTURES CONTRACTS A futures contract is an agreement between two parties to buy and sell a financial instrument at a set price on a future date. Upon entering into such a contract, the Fund is required to pledge to the broker an amount of cash or securities equal to the minimum "initial margin" requirements of the exchange. Pursuant to the contracts, the Fund agrees to receive from or pay to the broker an amount of cash equal to the daily fluctuation in the value of the contracts. Such receipts or payments are known as "variation margin" and are recorded by the Fund as unrealized appreciation or depreciation. When the contracts are closed, the Fund records a realized gain or loss equal to the difference between the value of the contracts at the time they were opened and the value at the time they were closed. Any unrealized appreciation or depreciation recorded is simultaneously reversed. The use of futures transactions involves the risk of 15 an imperfect correlation in the movements in the price of futures contracts, interest rates and the underlying hedged assets, and the possible inability of counterparties to meet the terms of their contracts. (k) CREDIT-LINKED TRUST CERTIFICATES Credit-linked trust certificates are investments in a limited purpose trust or other vehicle formed under state law which, in turn, invests in a basket of derivative instruments, such as credit default swaps, interest rate swaps and other securities, in order to provide exposure to the high yield or another fixed income market. Like an investment in a bond, investments in these credit-linked trust certificates represent the right to receive periodic income payments (in the form of distributions) and payment of principal at the end of the term of the certificate. However, these payments are conditioned on the trust's receipt of payments from, and the trust's potential obligations to, the counterparties to the derivative instruments and other securities in which the trust invests. (l) WHEN-ISSUED/DELAYED-DELIVERY TRANSACTIONS The Fund may purchase or sell securities on a when-issued or delayed-delivery basis. These transactions involve a commitment to purchase or sell securities for a predetermined price or yield, with payment and delivery taking place beyond the customary settlement period. When delayed-delivery purchases are outstanding, the Fund will set aside and maintain until the settlement date in a designated account, liquid assets in an amount sufficient to meet the purchase price. When purchasing a security on a delayed-delivery basis, the Fund assumes the rights and risks of ownership of the security, including the risk of price and yield fluctuations, and takes such fluctuations into account when determining its net asset value. The Fund may dispose of or renegotiate a delayed-delivery transaction after it is entered into, and may sell when-issued securities before they are delivered, which may result in a realized gain or loss. When the Fund sells a security on a delayed-delivery basis, the Fund does not participate in future gains and losses with respect to the security. (m) REVERSE REPURCHASE AGREEMENTS The Fund engages in reverse repurchase agreements in order to add leverage to the Fund's portfolio. In a reverse repurchase agreement, the Fund sells securities to a bank or broker-dealer and agrees to repurchase the securities at a mutually agreed upon date and price. Generally, the effect of such a transaction is that the Fund can recover and reinvest all or most of the cash invested in the portfolio securities involved during the term of the reverse repurchase agreement and still be entitled to the returns associated with those portfolio securities. Such transactions are advantageous if the interest cost to the Fund of the reverse repurchase transaction is less than the return it obtains on investments purchased with the cash. Unless the Fund covers its positions in reverse repurchase agreements (by segregating liquid assets at least equal in amount to the forward purchase commitment), its obligations under the agreements will be subject to the Fund's limitations on borrowings. Reverse repurchase agreements involve leverage risk and also the risk that the market value of the securities that the Fund is obligated to repurchase under the agreement may decline below the repurchase price. In the event the buyer of securities under a reverse repurchase agreement files for bankruptcy or becomes insolvent, the Fund's use of the proceeds of the agreement may be restricted pending a determination by the other party, or its trustee or receiver, whether to enforce the Fund's obligation to repurchase the securities. (n) CUSTODY CREDITS ON CASH BALANCES The Fund benefits from an expense offset arrangement with its custodian bank whereby uninvested cash balances earn credits which reduce monthly custodian expenses. Had these cash balances been invested in income producing securities, they would have generated income for the Fund. 2. INVESTMENT MANAGER AND SUB-ADVISER The Fund has entered into an Investment Management Agreement (the "Agreement") with the Investment Manager to serve as Investment Manager of the Fund. Subject to the supervision of the Fund's Board of Trustees, the Investment Manager is responsible for managing, either directly or through others selected by it, the investment activities of the Fund and the Fund's business affairs and other administrative matters. Pursuant to the Agreement, the Investment Manager will receive an annual fee, payable monthly, at an annual rate of 0.60% of the Fund's average daily net assets (inclusive of net assets attributable to any preferred shares that may be outstanding.) The Investment Manager has retained its affiliate, Pacific Investment Management Company LLC (the "Sub-Adviser"), to manage the Fund's investments. Subject to the supervision of the Investment Manager, the Sub-Adviser makes all 16 investment decisions with respect to the Fund's assets. The Investment Manager (not the Fund) pays a portion of the fees it receives to the Sub-Adviser in return for its services, at the maximum annual rate of 0.39% of the Fund's average daily net assets (inclusive of net assets attributable to any preferred shares that may be outstanding) for the period from commencement of operations through December 31, 2007 and at the maximum annual rate of 0.55% of average daily net assets (inclusive of net assets attributable to any preferred shares that may be outstanding) thereafter while the Agreement remains in effect, provided that the fee will be reduced to 0.325% during the first five years of operations and 0.45% thereafter while the Agreement remains in effect. The Investment Manager informed the Fund that it paid the Sub-Adviser $5,304,040 in connection with its sub-advisory services for the period ended November 30, 2003. 3. INVESTMENTS IN SECURITIES For the period ended November 30, 2003, purchases and sales of investments, other than short-term securities, were $1,811,927,909 and $357,716,014, respectively.

INCOME TAX INFORMATION The tax character of dividends paid for the period December 27, 2002 (commencement of operations) through November 30, 2003 of $92,742,601 was comprised entirely of ordinary income. At November 30, 2003, the tax character of distributable earnings of $31,877,844 was comprised entirely of ordinary income. 5. AUCTION PREFERRED SHARES The Fund has issued 4,520 shares of Preferred Shares Series M, 4,520 shares of Preferred Shares Series T, 4,520 shares of Preferred Shares Series W, 4,520 shares of Preferred Shares Series TH, and 4,520 shares of Preferred Shares Series F each with a net asset and liquidation value of $25,000 per share plus accrued dividends. Dividends are accumulated daily at an annual rate set through auction procedures. Distributions of net realized capital gains, if any, are paid annually. For the period ended November 30, 2003, the annualized dividend rate ranged from: HIGH LOW AT NOVEMBER 30, 2003 ------------------------------------------------------------------------------------- Series M 1.375% 1.00% 1.18% Series T 1.375% 1.069% 1.18% Series W 1.375% 1.06% 1.20% Series TH 1.375% 1.059% 1.20% Series F 1.375% 1.07% 1.20% The Fund is subject to certain limitations and restrictions while Preferred Shares are outstanding. Failure to comply with these limitations and restrictions could preclude the Fund from declaring any dividends or distributions to common shareholders or repurchasing common shares and/or could trigger the mandatory redemption of Preferred Shares at their liquidation value. Preferred Shares, which are entitled to one vote per share, generally vote with the common stock but vote separately as a class to elect two Trustees and on any matters affecting the rights of the Preferred Shares. 6. SUBSEQUENT COMMON DIVIDEND AND DISTRIBUTION DECLARATIONS On December 1, 2003, a dividend of $0.1375 per share was declared to common shareholders payable December 31, 2003 to shareholders of record on December 12, 2003.

SEE ACCOMPANYING NOTES TO FINANCIAL STATEMENTS 19 PIMCO CORPORATE OPPORTUNITY FUND REPORT OF INDEPENDENT AUDITORS TO THE SHAREHOLDERS AND BOARD OF TRUSTEES OF PIMCO CORPORATE OPPORTUNITY FUND In our opinion, the accompanying statement of assets and liabilities, including the schedule of investments, and the related statements of operations and of changes in net assets applicable to common shareholders and the financial highlights present fairly, in all material respects, the financial position of PIMCO Corporate Opportunity Fund (the "Fund") at November 30, 2003, and the results of its operations, the changes in its net assets applicable to common shareholders and the financial highlights for the period December 27, 2002 (commencement of operations) through November 30, 2003, in conformity with accounting principles generally accepted in the United States of America. These financial statements and financial highlights (hereafter referred to as "financial statements") are the responsibility of the Fund's management; our responsibility is to express an opinion on these financial statements based on our audit. We conducted our audit of these financial statements in accordance with auditing standards generally accepted in the United States of America, which require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audit, which included confirmation of securities at November 30, 2003 by correspondence with the custodian and brokers, provides a reasonable basis for our opinion. PricewaterhouseCoopers LLP New York, New York January 16, 2004 20 PIMCO CORPORATE OPPORTUNITY FUND DIVIDEND REINVESTMENT PLAN (UNAUDITED) Pursuant to the Fund's Dividend Reinvestment Plan (the "Plan"), all Common Shareholders whose shares are registered in their own names will have all dividends, including any capital gain dividends, reinvested automatically in additional Common Shares by PFPC Inc., as agent for the Common Shareholders (the "Plan Agent"), unless the shareholder elects to receive cash. An election to receive cash may be revoked or reinstated at the option of the shareholder. In the case of record shareholders such as banks, brokers or other nominees that hold Common Shares for others who are the beneficial owners, the Plan Agent will administer the Plan on the basis of the number of Common Shares certified from time to time by the record shareholder as representing the total amount registered in such shareholder's name and held for the account of beneficial owners who are to participate in the Plan. Shareholders whose shares are held in the name of a bank, broker or nominee should contact the bank, broker or nominee for details. All distributions to investors who elect not to participate in the Plan (or whose broker or nominee elects not to participate on the investor's behalf), will be paid cash by check mailed, in the case of direct shareholder, to the record holder by PFPC Inc., as the Fund's dividend disbursement agent. Unless you (or your broker or nominee) elect not to participate in the Plan, the number of Common Shares you will receive will be determined as follows: (1) If Common Shares are trading at or above net asset value on the payment date, the Fund will issue new shares at the greater of (i) the net asset value per Common Share on the payment date or (ii) 95% of the market price per Common Share on the payment date; or (2) If Common Shares are trading below net asset value (minus estimated brokerage commissions that would be incurred upon the purchase of Common Shares on the open market) on the payment date, the Plan Agent will receive the dividend or distribution in cash and will purchase Common Shares in the open market, on the New York Stock Exchange or elsewhere, for the participants' accounts. It is possible that the market price for the Common Shares may increase before the Plan Agent has completed its purchases. Therefore, the average purchase price per share paid by the Plan Agent may exceed the market price on the payment date, resulting in the purchase of fewer shares than if the dividend or distribution had been paid in Common Shares issued by the Fund. The Plan Agent will use all dividends and distributions received in cash to purchase Common Shares in the open market on or shortly after the payment date, but in no event later than the ex-dividend date for the next distribution. Interest will not be paid on any uninvested cash payments. You may withdraw from the Plan at any time by giving notice to the Plan Agent. If you withdraw or the Plan is terminated, you will receive a certificate for each whole share in your account under the Plan and you will receive a cash payment for any fraction of a share in your account. If you wish, the Plan Agent will sell your shares and send you the proceeds, minus brokerage commissions. The Plan Agent maintains all shareholders' accounts in the Plan and gives written confirmation of all transactions in the accounts, including information you may need for tax records. The Plan Agent will also furnish each person who buys Common Shares with written instructions detailing the procedures for electing not to participate in the Plan and to instead receive distributions in cash. Common Shares in your account will be held by the Plan Agent in non-certificated form. Any proxy you receive will include all Common Shares you have received under the Plan. There is no brokerage charge for reinvestment of your dividends or distributions in Common Shares. However, all participants will pay a pro rata share of brokerage commissions incurred by the Plan Agent when it makes open market purchases. Automatically reinvested dividends and distributions are taxed in the same manner as cash dividends and distributions. The Fund and the Plan Agent reserve the right to amend or terminate the Plan. There is no direct service charge to participants in the Plan; however, the Fund reserves the right to amend the Plan to include a service charge payable by the participants. Additional information about the Plan may be obtained from the Fund's transfer agent, PFPC Inc., P.O.Box 43027, Providence, RI 02940-3027, telephone number 1-800-331-1710. 21 PIMCO CORPORATE OPPORTUNITY FUND TAX & OTHER INFORMATION, PROXY VOTING POLICIES AND PROCEDURES TAX INFORMATION (UNAUDITED): Subchapter M of the Internal Revenue Code of 1986, as amended, requires the Fund to advise shareholders within 60 days of the Fund's tax year-end (November 30, 2003) as to the federal tax status of dividends and distributions received by shareholders during such tax year. Per share dividends for the tax year ended November 30, 2003 were as follows: Dividends to common shareholders from ordinary income $ 1.373 Dividends to preferred shareholders from ordinary income $ 233.287 Since the Fund's tax year is not the calendar year, another notification will be sent with respect to calendar year 2003. In January 2004, shareholders will be advised on IRS Form 1099 DIV as to the federal tax status of the dividends and distributions received during calendar 2003. The amount that will be reported, will be the amount to use on your 2003 federal income tax return and may differ from the amount which must be reported in connection with the Fund's tax year ended November 30, 2003. Shareholders are advised to consult with their tax advisers as to the federal, state and local tax status of the income received from the Fund. OTHER INFORMATION: Since December 27, 2002, (commencement of operations) there have been no: (i) material changes in the Fund's investment objectives or policies; (ii) changes to the Fund's charter or by-laws; (iii) material changes in the principal risk factors associated with investment in the Fund; or (iv) change in the persons primarily responsible for the day-to-day management of the Fund's portfolio.
