THE OAKMARK FUNDS

Notes to the Schedules of Investments (Unaudited)

1.  SIGNIFICANT ACCOUNTING POLICIES

Harris Associates Investment Trust (the “Trust”) is registered under the Investment Company Act of 1940, as amended (the “1940 Act”), as an investment company organized as a Massachusetts business trust.  The Trust consists of the following series (each individually referred to as “a Fund” or collectively as “the Funds”): The Oakmark Fund (“Oakmark”), The Oakmark Select Fund (“Select”), 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”).

Security valuation —

The Funds’ share prices or net asset values (“NAV”) are calculated as of the close of regular session trading (usually 4:00 pm Eastern time) on the New York Stock Exchange (“NYSE”) on any day on which the NYSE is open for trading. Domestic equity 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. Foreign equity securities traded on securities exchanges shall be valued at, depending on local convention or regulation, the last sales price, last bid or asked price, the mean between the last bid and asked prices, an official closing price, or shall be based on a pricing composite as of the close of the regular trading hours on the appropriate exchange or other designated time. 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 sales price on the day of valuation, or lacking any reported sales that day, at the mean of the most recent bid and asked quotations, or if the mean is not available, at the most recent bid quotation. Securities for which quotations are not readily available or securities that may have been affected by a significant event occurring between the close of a foreign market and the close of the NYSE are valued at fair values, determined by or under the direction of the pricing committee established by the Board of Trustees. A significant event may include the performance of U.S. markets since the close of foreign markets. The pricing committee 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 June 30, 2006, the Funds held no securities for which quotations were not readily available, and no securities that were believed to be affected by a significant event prior to the computation of the NAV.

Foreign currency translations —

Values of investments and other assets and liabilities denominated in foreign currencies are translated into U.S. dollars at current exchange rates obtained by a recognized bank, dealer, or independent pricing service on the day 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. Forward foreign currency contracts are valued at the current day’s interpolated foreign exchange rates. 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 and unrealized gains and losses from securities. Net realized gains and 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 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.

Forward foreign currency contracts—

The Funds’ currency transactions are limited to transaction hedging and portfolio hedging. 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 June 30, 2006 the Funds did not have any outstanding forward foreign currency contracts.

Repurchase agreements —

Each Fund may invest in repurchase agreements, which are short-term investments whereby the Fund acquires ownership of a debt security and the seller agrees to repurchase the security in the future at a specified price.

Each Fund, through IBT, receives delivery of the underlying securities collateralizing repurchase agreements.  It is each Fund’s policy that the value of the collateral be at least equal to 105% of the repurchase price, including interest. Harris Associates L.P. (“the 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.

Security lending—

Each Fund, except Oakmark Fund, 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 counterparty 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 or lack of access to income during that period.

At June 30, 2006 Equity and Income and International had securities on loan with values of approximately $397,765,600 and $141,684,973, respectively, and received $411,685,043 and $144,910,675 of U.S. Treasury and Fannie Mae securities as collateral for the loans, respectively.

Restricted Securities —

The following investments, the sales of which are restricted to qualified institutional buyers, have been valued according to the securities valuation procedures for debt obligations and money market instruments (as stated in the Security Valuation section) since their acquisition dates. These securities are priced using market quotations and there are no unrestricted securities with the same maturity dates and yields for this issuer.
