Notes to Financial Statements

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 the Harris Associates Investment Trust (a Massachusetts business trust). These policies are in conformity with accounting principles generally accepted in the United States ("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 Fund. This service fee is paid to an administrator for performing the services associated with the administration of such retirement plans.

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. At this time, expenses directly attributable to each class are transfer agent fees, service fees and other shareholder servicing fees.

Security valuation —

Investments are stated at market value. Securities traded on securities exchanges, securities traded on the NASDAQ National Market, and Over-the-counter securities are valued at the last sales price on the day of valuation, or if lacking any reported sales that day, at the most recent bid quotation. Debt obligations and money market instruments maturing in more than 60 days from the date of purchase shall be 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 if 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 are valued at a fair value as determined by the Pricing Committee appointed by the Board of Trustees.

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 investments.

Net realized gains 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 on the Funds' books, 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.

At March 31, 2002, only the Global, International and Int'l Small Cap Funds had foreign currency transactions. Net unrealized appreciation (depreciation)-other includes 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 the accrual basis.

Fund shares are sold and redeemed on a continuing basis at net asset value. Net asset value per share is determined daily as of the close of regular trading on the New York Stock Exchange on each day the Exchange is open for trading by dividing the total value of the Fund's investments and other assets, less liabilities, by the number of Fund shares outstanding.

Forward foreign currency contracts —

At March 31, 2002, Global, International and Int'l Small Cap had entered into forward foreign currency contracts under which they are obligated to exchange currencies at specified future dates. 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.

The Global Fund had the following outstanding contracts at March 31, 2002:

Transaction Hedges: Foreign Currency Purchases —

The International Fund had the following outstanding contracts at March 31, 2002:

Transaction Hedges: Foreign Currency Purchases —

The Int'l Small Cap Fund had the following outstanding contracts at March 31, 2002:

Transaction Hedges: Foreign Currency Purchases —

Transaction Hedges: Foreign Currency Sales —

At March 31, 2002, Global, International and Int'l Small Cap Funds each had sufficient cash and/or securities to cover any commitments under these contracts.

Federal income taxes, dividends and distributions to shareholders —

No provision is made for Federal income taxes. The Funds elect to be taxed as "regulated investment companies" and make such distributions to their shareholders as to be relieved of all Federal income taxes under provisions of current Federal tax law.

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

Bank Loans —

The Funds have an unsecured line of credit with Investors Bank & Trust. It is a committed line of $250 million. Borrowings under this arrangement bear interest at .45% above the Federal Funds Effective Rate. As of March 31, 2002, there were no outstanding borrowings.

Accounting for Options —

When the 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, which expire unexercised, 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.

During the six months ended March 31, 2002, Oakmark, Select, Small Cap, Equity & Income, and Global wrote option contracts. At March 31, 2002, Small Cap, Equity & Income, and Global had outstanding option contracts. Portfolio securities valued at $3,517,000, $12,032,280, and $11,610,710 were being held in escrow by the custodian as cover for call options and put options written by Small Cap, Equity & Income, and Global.
