(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 and capital gain distributions 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 per share dividend to common shareholders by the market price per common share. 2 PIMCO CORPORATE OPPORTUNITY FUND SCHEDULE OF INVESTMENTS May 31, 2003 (unaudited) PRINCIPAL AMOUNT CREDIT RATING (000) (MOODY'S/S&P) VALUE* ---------------------------------------------------------------------------------------------------------------- LONG-TERM INVESTMENTS--97.2% CORPORATE BONDS & NOTES - 85.8% AIRLINES - 4.9% Continental Airlines, Inc., pass thru certificates, $ 4,656 6.703%, 6/15/21, Ser. 01-1 Baa3/A $ 4,303,612 3,500 7.373%, 12/15/15, Ser. 01-1 Ba1/BBB+ 2,471,476 2,000 7.487%, 4/2/12, Ser. 00-2 Baa3/A 1,868,244 10,902 7.707%, 10/2/22, Ser. 00-2 Baa3/A- 10,185,876 Delta Airlines, Inc., pass thru certificates, 9,455 7.57%, 5/18/12, Ser. 00-1 Baa2/A 9,380,306 13,580 7.92%, 5/18/12, Ser. 00-1 Baa3/BBB 10,792,542 Northwest Airlines Corp., pass thru certificates, 15,100 6.841%, 10/1/12, Ser. 01-1 Baa3/A+ 14,536,861 5,836 7.575%, 3/1/19, Ser. 992A Baa2/A+ 5,792,081 United Airlines, Inc., pass thru certificates, 15,411 7.186%, 4/1/11, Ser. 00-2 Baa3/BBB- 12,483,097 10,000 7.73%, 7/1/10, Ser. 00-1 Baa3/BBB- 7,486,950 -------------- 79,301,045 ============== AUTOMOTIVE - 2.5% 4,000 Auburn Hills Trust 12.375%, 5/1/20 A3/BBB+ 6,228,412 24,500 Ford Motor Co., 7.45%, 7/16/31 Baa1/BBB 22,856,393 10,000 General Motors Corp., 9.40%, 7/15/21 A3/BBB 11,467,530 -------------- 40,552,335 ============== BANKING - 0.6% 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. Offering costs of $1,573,068 (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 has agreed to pay all offering costs (other than the sales load) and organizational expenses exceeding $0.03 per share. In addition, the underwriters' commission and offering costs associated with the issuance of Preferred Shares in the amounts of $5,650,000 and $575,000, 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 occurred. 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 assets for which market quotations are readily available are valued each day at market value. Market value is generally determined on the basis of the last reported sales price, or if no sales are reported, based on quotes obtained from a quotation reporting system, established market makers, or independent pricing services approved by the Board of Trustees. Any security or other asset for which market quotations are not readily available is valued at fair value as determined in good faith under procedures established by the Board of Trustees. The Fund invests substantially all of its assets in a diversified portfolio of corporate debt obligations of varying maturities and other corporate income-producing securities. Short-term debt securities having a remaining maturity of sixty days or less are valued at amortized cost or amortized value, which approximates market value. Forward currency contracts are valued at prevailing forward exchange rates of the underlying currencies. (b) 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 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. (c) 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. Market discount, if any, is accreted daily. 12 (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) INTEREST RATE SWAPS The Fund may invest in interest rate swap contracts ("swaps") for investment purposes, to manage its interest rate risk and to add leverage. 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 part of 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 and market 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. Interest rate swap contracts outstanding at May 31, 2003 were as follows: RATE TYPE ----------------------------------------- NOTIONAL SWAP AMOUNT TERMINATION PAYMENTS RECEIVED BY PAYMENTS MADE BY UNREALIZED COUNTERPARTY (IN 000) DATE THE FUND THE FUND DEPRECIATION ---------------------------------------------------------------------------------------------------- Goldman Sachs $ 55,000 3/18/05 1 week LIBOR 1.813% $ 389,950 ========== (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 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. 13 (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 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. Forward foreign currency contracts outstanding at May 31, 2003 were: U.S.$ VALUE ON U.S.$ VALUE UNREALIZED SOLD: ORIGINATION DATE APRIL 30, 2003 DEPRECIATION --------------------------------------------------------------------------------------------- 31,481,000 Euros, settling 6/25/03 $ 36,192,762 $ 36,998,875 $ 806,113 ========= (h) OPTION TRANSACTIONS For hedging purposes, the Fund may purchase and write (sell) put and call options on Municipal Bonds, U.S. government securities, swap agreements, indexes or futures contracts which are standardized and traded on a U.S. or other exchange, boards of trade, or similar entity, or quoted on an automated quotation system. 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. Transactions in options written for the period ended May 31, 2003 were: CONTRACTS PREMIUMS ------------------------------------------------------------------------------ Options outstanding, beginning of period - - Options written 1,126 $ 1,330,543 ----- ----------- Options outstanding at May 31, 2003 1,126 $ 1,330,543 ----- ----------- (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) 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. 14 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 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, if and while the Investment Manager is obligated to pay a fee to Merrill Lynch, Pierce Fenner & Smith, Inc. ("Merrill Lynch"), the underwriter of the Fund's shares. The Investment Manager (not the Fund) has agreed to pay a quarterly fee to Merrill Lynch at the annual rate of 0.10% of the Fund's average daily net assets (inclusive of net assets attributable to any preferred shares that may be outstanding) during the continuance of the Agreement. The Investment Manager informed the Fund that it paid the Sub-Adviser $2,133,643 in connection with its sub-advisory services for the period ended May 31, 2003. 3. INVESTMENTS IN SECURITIES For the period ended May 31, 2003, purchases and sales of investments, other than short-term securities, were $1,441,203,045 and $35,622,477, respectively. 4. 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 May 31, 2003, the annualized dividend rate ranged from: HIGH LOW AT MAY 31, 2003 ----------------------------------------------------------------------------------- Series M 1.375% 1.25% 1.32% Series T 1.375% 1.30% 1.35% Series W 1.375% 1.25% 1.33% Series TH 1.375% 1.25% 1.35% Series F 1.375% 1.30% 1.30% 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. 15 5.
