(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 September 30, 2003. 2 <Page> PIMCO HIGH INCOME FUND SCHEDULE OF INVESTMENTS September 30, 2003 (unaudited) <Table> <Caption> PRINCIPAL AMOUNT CREDIT RATING (000) (MOODY'S/S&P) VALUE* - ----------------------------------------------------------------------------------------------------------- CORPORATE BONDS & NOTES - 86.5% ADVERTISING - 0.5% $ 3,600 American Color Graphics, Inc., 10.00%, 6/15/10 (a) (d) (acquired 7/8/03-7/15/03; cost-$3,677,500) B3/B $ 3,825,000 6,900 RH Donnelley Finance Corp., 8.875%, 12/15/10 (a) (d) (acquired 5/14/03-7/30/03, cost-$7,599,191) B1/B+ 7,762,500 ---------------- 11,587,500 ================ AEROSPACE - 0.2% 5,600 Armor Holdings, Inc., 8.25%, 8/15/13 (a) (d) (acquired 8/6/03; cost-$5,507,639) B1/B+ 5,950,000 ---------------- AIRLINES - 1.3% Continental Airlines, Inc., pass thru certificates, 20,000 6.92%, 4/2/13, 97-5A (b) (c) (d) (e) (acquired 7/1/03; cost $17,807,138) NR/NR 18,405,468 6,500 7.373%, 12/15/15, Ser. 01-1 Ba1/BBB 4,943,200 10,000 Delta Air Lines, Inc., pass thru cerficates, Ser. 00-1, 7.92%, 5/18/12 Baa3/BBB 8,586,179 982 United Air Lines, Inc., pass thru cerficates, Ser. 00-2, 7.19%, 10/1/12 NR/NR 835,317 3,780 US Airways, Inc., Ser. 93-A2, 9.625%, 9/1/03 (e) NR/D 1,304,182 ---------------- 34,074,346 ================ AUTOMOTIVE - 2.0% 10,450 Arvin Capital I, 9.50%, 2/1/27 Ba2/B+ 10,188,750 11,851 Dura Operating Corp., Ser.

ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES PIMCO High Income Fund (the "Fund"), was organized as a Massachusetts business trust on February 18, 2003. Prior to commencing operations on April 30, 2003, 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 $0.00001 par value common stock authorized. The Fund's investment objective is to seek high current income. Capital appreciation is a secondary objective. The Fund attempts to achieve these objectives by investing in a diversified portfolio of U.S. dollar-denominated debt obligations and other income-producing securities that are primarily rated below investment grade. The Fund issued 105,000,000 shares of common stock in its initial public offering. An additional 8,900,000 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 $1,650,000 (representing $0.014 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 common 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 share, 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 $9,000,000 and $625,000, 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 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 The Fund determines its net asset value 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. Debt securities are valued by an independent pricing service approved by the Board of Trustees. Certain 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 independent pricing services. Any security or financial instrument 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. Short-term investments having a remaining maturity of sixty days or less are valued at amortized cost, which approximates market value. (b) INVESTMENT TRANSACTIONS AND INVESTMENT INCOME Investment transactions are accounted for on the 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. 16 <Page> (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 considered either 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 SWAPS The Fund enters into credit default swap contracts ("swaps") for hedging purposes 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 the portfolio, in which case the Fund would function as the counterparty referenced in the preceding paragraph. As a purchaser of 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 by the Fund. 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 Statement of Operations by the Fund. 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. 17 <Page> Credit default swap contracts outstanding at September 30, 2003 were: <Table> <Caption> NOTIONAL SWAP AMOUNT FIXED COUNTERPARTY/ PAYABLE ON PAYMENTS REFERENCED DEBT DEFAULT TERMINATION RECEIVED BY UNREALIZED OBLIGATION (000) DATE THE FUND APPRECIATION - ---------------------------------------------------------------------------------------------------------- Bear Stearns Co., Inc Allied Waste North America 7.875%, 1/1/09 $ 1,250 9/20/04 5.50% -- Bombardier Capital, Inc. 6.125%, 6/29/06 5,000 9/20/04 2.70% $ 39,000 Nextel Communication, Inc. 9.375%, 11/15/02 1,250 9/20/04 5.50% -- Starwood Hotels & Resorts Worldwide, Inc. 7.875%, 5/1/12 1,250 9/20/04 5.50% -- Tyco International Group SA 2.75%, 1/15/18 1,250 9/20/04 5.50% -- Goldman Sachs & Co.

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. 18 <Page> (g) 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 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 returns 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. The weighted average daily balance of reverse repurchase agreements outstanding during the period ended September 30, 2003 was $9,540,000 at a weighted average interest rate of 0.25%. (h) FORWARD FOREIGN CURRENCY CONTRACTS A forward foreign currency contract is an agreement between two parties to buy and sell a currency at a set exchange rate on a future date. The Fund may enter into forward foreign currency contracts for the purpose of hedging against foreign currency risk arising from the investment or anticipated investment in securities denominated in foreign currencies. The Fund may also enter these contracts for purposes of increasing exposure to a foreign currency or to shift exposure to foreign currency fluctuations from one country to another. The market value of a forward foreign currency contract fluctuates with changes in forward currency exchange rates. All commitments are marked to market daily at the applicable exchange rates and any resulting unrealized gains and losses are recorded. Realized gains or losses are recorded at the time the forward contract matures or by delivery of the currency. Risks may arise upon entering these contracts from the potential inability of counterparties to meet the terms of their contracts and from unanticipated movements in the value of a foreign currency relative to the U.S. dollar. Forward foreign currency contracts outstanding at September 30, 2003 were: <Table> <Caption> U.S.$ VALUE ON U.S.$ VALUE UNREALIZED SOLD: ORIGINATION DATE SEPTEMBER 30, 2003 DEPRECIATION - --------------------------------------------------------------------------------------------- Euros, settling 11/05/03 $ 8,233,779 $ 8,347,075 $ 113,296 ========= </Table> (i) OPTION TRANSACTIONS The Fund may purchase and write (sell) put and call options for hedging purposes, risk management purposes or as part of its investment strategy. 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. 19 <Page> Transactions in options written for the period ended September 30, 2003 were: <Table> <Caption> CONTRACTS PREMIUMS - ------------------------------------------------------------------------------ Options outstanding, beginning of period - - Options written 1,495 $ 1,224,918 Option expired (979) (658,872) Options terminated in closing purchase transactions (516) (566,046) ----- ----------- Options outstanding, September 30, 2003 - - ----- ----------- </Table> (j) 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. (k) 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. When investing in a loan participation, the Fund has the right to receive payments of principal, interest and any fees to which it is entitled only from the lender selling the loan agreement and only upon receipt by the lender of payments from the borrower. The Fund generally has no right to enforce compliance with the terms of the loan agreement with 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. (l) 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 and accounting agent fees. 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 receives an annual fee, payable monthly, at an annual rate of 0.70% 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 for the Fund. The Investment Manager (not the Fund) pays a portion of the fees it receives as Investment Manager to the Sub-Adviser in return for its services, at the maximum annual rate of 0.3575% 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 April 30, 2008 and at the maximum annual rate of 0.50% of average daily net assets, inclusive of net assets attributable to any preferred shares that may be outstanding, thereafter. The Investment Manager informed the Fund that it paid the Sub-Adviser $3,283,238 in connection with its sub-advisory services for the period ended September 30, 2003. 3. INVESTMENTS IN SECURITIES For the period ended September 30, 2003, purchases and sales of investments, other than short-term securities, were $2,884,075,870 and $430,782,148, respectively. 20 <Page> 4. AUCTION PREFERRED SHARES The Fund has issued 7,200 shares of Preferred Shares Series M, 7,200 shares of Preferred Shares Series T, 7,200 shares of Preferred Shares Series W, 7,200 shares of Preferred Shares Series TH, and 7,200 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 September 30, 2003, the annualized dividend rate ranged from: <Table> <Caption> HIGH LOW AT SEPTEMBER 30, 2003 - ---------------------------------------------------------------------------------- Series M 1.32% 1.05% 1.32% Series T 1.20% 1.05% 1.15% Series W 1.20% 1.05% 1.15% Series TH 1.28% 1.05% 1.28% Series F 1.30% 1.07% 1.30% </Table> 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. 5. SUBSEQUENT COMMON DIVIDEND DECLARATIONS On October 1, 2003, a dividend of $0.121875 per share was declared to common shareholders payable November 3, 2003 to shareholders of record on October 10, 2003. On November 3, 2003, a dividend of $0.121875 per share was declared to common shareholders payable December 1, 2003 to shareholders of record on November 14, 2003. 21 <Page> PIMCO HIGH INCOME FUND FINANCIAL HIGHLIGHTS For a share of common stock outstanding for the period April 30, 2003* through September 30, 2003: (unaudited) <Table> Net asset value, beginning of period $ 14.33** - -------------------------------------------------------------------------------------- ----------- INVESTMENT OPERATIONS: Net investment income 0.50 - -------------------------------------------------------------------------------------- ----------- Net realized and unrealized gain on investments, futures, options written, swaps and foreign currency transactions 0.53 - -------------------------------------------------------------------------------------- ----------- Total from investment operations 1.03 - -------------------------------------------------------------------------------------- ----------- DIVIDENDS ON PREFERRED SHARES FROM NET INVESTMENT INCOME (0.02) - -------------------------------------------------------------------------------------- ----------- Net increase in net assets applicable to common shares resulting from investment operations 1.01 - -------------------------------------------------------------------------------------- ----------- DIVIDENDS TO COMMON SHAREHOLDERS FROM NET INVESTMENT INCOME: (0.49) - -------------------------------------------------------------------------------------- ----------- CAPITAL SHARE TRANSACTIONS: Common stock offering costs charged to paid-in capital in excess of par (0.01) - -------------------------------------------------------------------------------------- ----------- Preferred shares offering costs/underwriting discount charged to paid-in capital in excess of par (0.09) - -------------------------------------------------------------------------------------- ----------- Total capital share transactions (0.10) - -------------------------------------------------------------------------------------- ----------- Net asset value, end of period $ 14.75 - -------------------------------------------------------------------------------------- ----------- Market price, end of period $ 13.98 - -------------------------------------------------------------------------------------- ----------- TOTAL INVESTMENT RETURN (1) (3.55)% - -------------------------------------------------------------------------------------- ----------- RATIOS/SUPPLEMENTAL DATA: Net assets applicable to common shareholders, end of period (000) $ 1,684,904 - -------------------------------------------------------------------------------------- ----------- Ratio of expenses to average net assets (2)(3)(4) 1.09% - -------------------------------------------------------------------------------------- ----------- Ratio of net investment income to average net assets (2)(4) 8.41% - -------------------------------------------------------------------------------------- ----------- Preferred shares asset coverage per share $ 71,796 - -------------------------------------------------------------------------------------- ----------- Portfolio turnover 25% - -------------------------------------------------------------------------------------- ----------- </Table> * Commencement of operations. ** Initial public offering price of $15.00 per share less underwriting discount of $0.675 per share.
