Notes to Financial Statements—(Unaudited)

1. SIGNIFICANT ACCOUNTING POLICIES

The following are the significant accounting policies of The Oakmark Fund ("Oakmark"), The Oakmark Select Fund ("Select"), The Oakmark Small Cap Fund ("Small Cap"), The Oakmark Equity and Income Fund ("Equity and Income"), The Oakmark Global Fund ("Global"), The Oakmark International Fund ("International"), and The Oakmark International Small Cap Fund ("Int'l Small Cap") collectively referred to as "the Funds", each a series of Harris Associates Investment Trust (the "Trust"), a Massachusetts business trust, which is registered as an investment company under the Investment Company Act of 1940. These policies are in conformity with accounting principles generally accepted in the United States of America ("GAAP"). The presentation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates and assumptions.

Class disclosure—

Each Fund offers two classes of shares: Class I Shares and Class II Shares. Class I Shares are offered to the general public. Class II Shares are offered to certain retirement plans such as 401(k) and profit sharing plans. Class II Shares pay a service fee at the annual rate of .25% of average net assets of Class II Shares of the Funds. This service fee is paid to an administrator for performing the services associated with the administration of such retirement plans.

Income, realized and unrealized capital gains and losses and expenses of the Funds that are not directly attributable to a specific class of shares are prorated among the classes based on the relative net assets of each class. Expenses directly attributable to a class of shares are recorded to the specific class.

Redemption fees—

Each Fund imposes a short-term trading fee on redemptions of Class I Shares held for 90 days or less to offset two types of costs to the Fund caused by short-term trading: portfolio transaction and market impact costs associated with erratic redemption activity and administrative costs associated with processing redemptions. The fee is 2% of the redemption value and is deducted from the redemption proceeds and retained by the Fund. The "first-in, first-out" (FIFO) method is used to determine the holding period.

Security valuation—

Securities traded on securities exchanges and over-the-counter securities are valued at the last sales price on the day of valuation, or lacking any reported sales that day, at the most recent bid quotation. Securities traded on the NASDAQ National Market are valued at the NASDAQ Official Closing Price ("NOCP"), or lacking an NOCP, at the most recent bid quotation on the NASDAQ National Market. Debt obligations and money market instruments maturing in more than 60 days from the date of purchase are valued at the latest bid quotation. Debt obligations and money market instruments maturing in less than 61 days from the date of purchase are valued on an amortized cost basis which approximates market value. Options are valued at the last reported sale price on the day of valuation, or lacking any reported sales that day, at the mean of the most recent bid and ask quotations. Securities for which quotations are not readily available, or securities which may have been affected by a significant event after the price was determined, and other assets are valued at a fair value as determined by or under the direction of pricing committees established by the Board of Trustees. Securities traded in foreign markets are valued using prices reported by local foreign markets. The Funds' net asset values are determined at the time of the close of the New York Stock Exchange. The pricing committees will evaluate movements in the U.S. markets after the close of foreign markets and may adjust security prices to reflect changes in reaction to U.S. markets as determined by a third party model. At March 31, 2004, the Funds held one security for which a quotation was not readily available, and no securities which may have been affected by a significant event after the price was determined.

Foreign currency translations—

Values of investments and other assets and liabilities denominated in foreign currencies are translated into U.S. dollars using the mean of the bid and offer prices of such currencies at the time of valuation. Purchases and sales of investments and dividend and interest income are converted at the prevailing rate of exchange on the respective dates of such transactions.

The Funds do not isolate that portion of the results of operations resulting from changes in foreign exchange rates on investments from the fluctuations arising from changes in market prices of securities held. Such fluctuations are included with the net realized gain or loss from securities.

Net realized gains or losses on foreign currency transactions arise from sales of foreign currencies, currency gains or losses realized between the trade and settlement dates on securities transactions, the difference between the amounts of dividends, interest, and foreign withholding taxes recorded and the U.S. dollar equivalent of the amounts actually received or paid, and the realized gains or losses resulting from the portfolio and transaction hedges. Net unrealized foreign exchange gains and losses arise from changes in the fair value of assets and liabilities, other than investments in securities at fiscal year end, resulting from changes in exchange rates.

For the period ended March 31, 2004, net unrealized appreciation (depreciation) - other included the following components:

Security transactions and investment income—

Security transactions are accounted for on the trade date (date the order to buy or sell is executed) and dividend income is recorded on the ex-dividend date. Interest income and expenses are recorded on an accrual basis. Bond discount is accreted and premium is amortized over the expected life of each applicable security. Withholding taxes on foreign dividends have been provided for in accordance with the Funds' understanding of the applicable country's tax rules and rates. Corporate gains taxes on the appreciation of certain foreign securities have been accrued for in accordance with the Funds' understanding of the applicable country's tax rules and rates, and are recorded as Deferred Foreign Taxes on the Statements of Operations. Net realized gains and losses on investments are determined by the specific identification method. Net realized gains and losses on investments are determined by the specific identification method.

Forward foreign currency contracts—

The Funds' currency transactions are limited to transaction hedging and portfolio hedging involving either specific transactions or portfolio positions.

The contractual amounts of forward foreign exchange contracts do not necessarily represent the amounts potentially subject to risk. The measurement of the risks associated with these instruments is meaningful only when all related and offsetting transactions are considered. Risks arise from the possible inability of counter parties to meet the terms of their contracts and from movements in currency values. At March 31, 2004, the Funds had no forward foreign currency contracts outstanding.

Distributions to shareholders—

Income, dividends and capital gains distributions are determined in accordance with federal income tax regulations, which may differ from GAAP. To the extent the tax and book differences are permanent in nature, such amounts are reclassified among paid in capital, undistributed net investment income and accumulated undistributed net realized gain (loss). Those differences are primarily related to foreign currency transactions, deferral of losses on wash sales, and character of capital loss carryforwards. The Funds also utilize, when appropriate, earnings and profits distributed to shareholders on redemption of shares as a part of the dividends paid deduction for income tax purposes.

Short sales—

The Fund may sell a security it does not own in anticipation of a decline in the fair value of that security. When the Fund sells a security short, it must borrow the security sold short and deliver it to the broker-dealer through which it made the short sale. A gain, limited to the price at which the Fund sold the security short, or loss, unlimited in size, will be recognized upon the termination of a short sale. At March 31, 2004, the Funds had no securities sold short.

Accounting for options—

When a Fund writes an option, the premium received by the Fund is recorded as a liability and is subsequently adjusted to the current market value of the option written. Premiums received from writing options that expire are recorded by the Fund on the expiration date as realized gains from option transactions. The difference between the premium 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 transaction, as a realized loss. If a call option is exercised, the premium is added to the proceeds from the sale of the underlying security or currency in determining whether the Fund has realized a gain or a loss. If a put option is exercised, the premium reduces the cost basis of the security or currency purchased by the Fund. In writing an option, the Fund bears the market risk of an unfavorable change in the price of the security or currency underlying the written option. Exercise of an option written by the Fund could result in the Fund selling or buying a security or currency at a price different from the current market value. Options written by the Funds do not give rise to counterparty credit risk, as they obligate the Funds, not their counterparties, to perform. At March 31, 2004, the Funds had no written options outstanding.

When a Fund purchases an option, the premium paid by the Fund is recorded as an asset and is subsequently adjusted to the current market value of the option purchased. Purchasing call options tends to increase the Fund's exposure to the underlying instrument. Purchasing put options tends to decrease the Fund's exposure to the underlying instrument. Premiums paid for purchasing options which expire are treated as realized losses. Premiums paid for purchasing options which are exercised or closed are added to the amounts paid or offset against the proceeds on the underlying security to determine the realized gain or loss. The risk associated with purchasing put and call options is potential loss of the premium paid. At March 31, 2004, the Funds held no options.

Committed line of credit—

The Funds have an unsecured committed line of credit with Investors Bank & Trust Company ("IBT") in the amount of $450 million. Borrowings under that arrangement bear interest at .45% above the Federal Funds Effective Rate. There were no borrowings during the period ended March 31, 2004.

Repurchase agreements—

Each Fund, through its custodian, receives delivery of the underlying securities collateralizing repurchase agreements. It is each Fund's policy that the market value of the collateral be at least equal to 105% of the repurchase price, including interest. Each Fund's adviser is responsible for determining that the value of the collateral is at all times at least equal to 105% of the repurchase price, including interest. Repurchase agreements could involve certain risks in the event of default or insolvency of the counterparty including possible delays or restrictions upon a Fund's ability to dispose of the underlying securities.

Expense offset arrangement—

IBT serves as custodian of the Funds. IBT's fee may be reduced by credits which are an earnings allowance calculated on the average daily cash balances each Fund maintains with IBT. Credit balances used to reduce the Funds' custodian fees, if any, would be reported as a reduction of total expenses in the Statements of Operations.

Security lending—

Each Fund except Oakmark may lend its portfolio securities to broker-dealers and banks. Any such loan must be continuously secured by collateral in cash or cash equivalents maintained on a current basis in an amount at least equal to the fair value of the securities loaned by the Fund. Collateral is marked to market and monitored daily. The Fund would continue to receive the equivalent of the interest or dividends paid by the issuer on the securities loaned, and would also receive an additional return that may be in the form of a fixed fee or a percentage of the earnings on the collateral. The Fund would have the right to call the loan and obtain the securities loaned at any time, and the bank shall return the securities within five business days or less. In the event of bankruptcy or other default of the borrower, the Fund could experience delays in liquidating the loan collateral or recovering the loaned securities and incur expenses related to enforcing its rights. In addition, there could be a decline in the value of the collateral or in the fair value of the securities loaned while the Fund seeks to enforce its rights thereto and the Fund could experience subnormal levels of income and lack of access to income during that period.

Reclassifications—

Certain amounts have been reclassified to conform with the current presentation.

2. TRANSACTIONS WITH AFFILIATES

Each Fund has an investment advisory agreement with Harris Associates L.P. ("Adviser"). For management services and facilities furnished, the Funds pay the Adviser monthly fees. Each fee is calculated on the total net assets as determined at the end of each preceding calendar month. Annual fee rates are as follows:

The Adviser undertakes to reimburse each Fund Class to the extent that its annualized expenses (excluding taxes, interest, all commissions and other normal charges incident to the purchase and sale of portfolio securities, and extraordinary charges such as litigation costs, but excluding fees paid to the Adviser) exceed the percent set forth opposite the Fund Class of average net assets of the Fund Class through January 31, 2005.

For the period ended March 31, 2004, the Funds incurred brokerage commissions, including commissions paid to an affiliate of the Adviser, Harris Associates Securities L.P., as follows:

CDC IXIS Asset Management Services Co., an affiliate of the Adviser, provides transfer agent services to the Funds. The fees are based on the number of open accounts and the reimbursement of out-of-pocket expenses. For the period ended March 31, 2004, the Funds incurred the following transfer agent expenses:

The Adviser has entered into agreements with service providers to provide recordkeeping, processing, shareholder communications and other services to the Funds. These services would be provided by the Funds if the shares were held in accounts registered directly with the Funds' transfer agent. Accordingly, the Funds pay a portion of these fees pursuant to a separate agreement with the Adviser. These fees are reflected as other shareholder servicing fees in the Statements of Operations.

The non-interested Trustees of the Trust may participate in the Trust's Deferred Compensation Plan for Independent Trustees. Participants in the plan may elect to defer all or a portion of their compensation. Amounts deferred are retained by the Trust and represent an unfunded obligation of the Trust. The value of amounts deferred for a participant is determined by reference to the change in value of Class I shares of one or more of the Funds or a money market fund as specified by the participant. Benefits under the plan are payable upon retirement. The interested trustees are not compensated by the Funds.

3. FEDERAL INCOME TAXES

It is the policy of each Fund to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute all of its net taxable income, including any net realized gains on investments, to its shareholders. Therefore, no federal income tax provision is required.

4. INVESTMENT TRANSACTIONS

For the period ended March 31, 2004, transactions in investment securities (excluding short term and U.S. Government securities) were as follows (in thousands):

Purchases at cost and proceeds from sales of long-term U.S. Government securities for the period ended March 31, 2004 were $536,365 and $46,003 respectively for Equity and Income.
