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 Equity and Income Fund (“Equity and Income”), The Oakmark Global Fund (“Global”), The Oakmark Global Select Fund (“Global Select”), 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, organized on February 1, 1991, 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 up to 0.25% 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. Class I Shares do not have an associated service fee.

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.

Redemption fees—

Each Fund (except Equity and Income as of October 29, 2007) imposes a short-term trading fee on redemptions of 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. The “first-in, first-out” (“FIFO”) method is used to determine the holding period.

Security valuation—

The Funds’ share prices or net asset values (“NAVs”) 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. Equity securities principally traded on securities exchanges in the United States 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. Equity securities principally traded on securities exchanges outside the United States shall be valued at, depending on local convention or regulation, at the last sales price, the last bid or asked price, the mean between the last bid and asked prices, or the 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 value. Options are valued at the last reported sales price on the day of valuation, or lacking any reported sale price on the valuation date, 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 appointed by the Board of Trustees evaluates 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 September 30, 2007, no Funds except Equity and Income held securities for which market quotations were not readily available. Equity and Income held a security whose market value was determined by procedures established in good faith by the Board of Trustees.

Foreign currency translations—

Certain Funds invest in foreign securities, which may involve a number of risk factors and special considerations not present with investments in securities of U.S. corporations. 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.

At September 30, 2007, net unrealized appreciation (depreciation) - other included the following components:

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 counterparties to meet the terms of their contracts and from movements in currency values. At September 30, 2007, Global, Global Select, International, and Int’l Small Cap held forward foreign currency contracts as follows:

The Oakmark Global Fund

The Oakmark Global Select Fund

The Oakmark International Fund

The Oakmark Int'l Small Cap Fund

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 using the effective yield method. Withholding taxes on foreign dividends have been provided for in accordance with the Funds’ understanding of the applicable country’s tax rules and rates. Net realized gains and losses on investments are determined by the specific identification method.

Short sales—

Each Fund may sell a security it does not own in anticipation of a decline in the 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 September 30, 2007, none of the funds had short sales.

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 Fund do not give rise to counterparty credit risk, as they obligate the Funds, not its counterparties, to perform.

When a Fund purchases an option, the premium paid by the Fund is recorded as an asset and is subsequently adjusted to the current 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 that expire are treated as realized losses. Premiums paid for purchasing options that 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 risks associated with purchasing put and call options are potential loss of the premium paid and the failure of the counterparty to honor its obligation under the contract.

At September 30, 2007, the Funds had no outstanding options.

Committed line of credit—

The Trust has an unsecured committed line of credit with State Street Bank and Trust Company (“State Street”) in the amount of $450 million. Borrowings under that arrangement bear interest at 0.45% above the Federal Funds Effective Rate, as defined in the credit agreement. There were no borrowings under the arrangement during the year ended September 30, 2007.

Expense offset arrangement—

State Street serves as custodian of the Funds. State Street’s fee may be reduced by credits that are an earnings allowance calculated on the average daily cash balances each Fund maintains with State Street. Credit balances used to reduce the Funds’ custodian fees, if any, are reported as a reduction of total expenses in the Statements of Operations. During the year ended September 30, 2007, Global Select had an expense offset arrangement of $193.

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 at a future date at a specified price.

The Fund, through State Street, receives delivery of the underlying securities collateralizing repurchase agreements. It is the Funds’ 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, 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 is required to 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 September 30, 2007, none of the Funds had securities on loan.

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 the issuer.

At September 30, 2007, Equity and Income held the following restricted securities:

Federal income taxes—

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

Recently issued accounting pronouncement—

In June2006,the Financial Accounting Standards Board (“FASB”) issued Interpretation No.48 (“FIN 48”) “Accounting for Uncertainty in Income Taxes—an interpretation of FASB Statement No.109”.This interpretation prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. It also provides guidance on de-recognition, classification, interest and penalties, accounting in interim periods, disclosure and transition. FIN 48 is effective for fiscal years beginning after December 15, 2006.

In September2006, FASB issued Statement of Financial Accounting Standards No.157 ("FAS 157"), "Fair Value Measurements." FAS 157 defines fair value, establishes a framework for measuring fair value in accordance with generally accepted accounting principles and expands disclosure about fair value measurements. FAS 157 is effective for fiscal years beginning after November 15, 2007.

In February2007, FASB issued Statement of Financial Accounting Standards No.159 ("FAS 159") "The Fair Value Option for Financial Assets and Financial Liabilities—including an amendment of FASB Statement No.115." FAS 159 permits entities to elect to measure certain financial assets and liabilities at fair value. Unrealized gains and losses on items for which the fair value option has been elected will be reported in earnings at each subsequent reporting date. FAS 159 is effective as of the beginning of the first fiscal year that begins after November15, 2007.

Management is currently evaluating the impact the adoption of these accounting pronouncements on the Funds’ financial statements and related disclosures.

2. TRANSACTIONS WITH AFFILIATES

Each Fund has an investment advisory agreement with the 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 is contractually obligated through January 31, 2008 to reimburse each Fund Class to the extent, but only 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 including fees paid to the Adviser) exceed the percent set forth below of average daily net assets of the Fund Class.

The Adviser and the Funds have entered into agreements with financial intermediaries to provide recordkeeping, processing, shareholder communications and other services to customers of the intermediaries and have agreed to compensate the intermediaries for providing those services. Certain of those services would be provided by the Funds if the shares of those customers were registered directly with the Funds’ transfer agent. Accordingly, the Funds pay a portion of the intermediary fees pursuant to an agreement with the Adviser, which calls for each Fund to pay a portion of the intermediary fees attributable to shares of the Fund held by the intermediary (which generally are a percentage of value of the shares held) not exceeding the lesser of 75% of the fees charged by the intermediary or what the Fund would have paid its transfer agent had each customer’s shares been registered directly with the transfer agent instead of held through the intermediary. The Adviser pays the remainder of the fees. The fees incurred by the Funds 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 would be payable after a stated number of years or retirement from the board. The accrued obligations of the Funds under the plan are reflected as deferred trustee compensation in the Statement of Assets and Liabilities. The interested trustees are not compensated by the Funds.

3. FEDERAL INCOME TAXES

For the year ended September 30, 2007, cost of investments for federal income tax purposes and related composition of unrealized gains and losses were as follows:

As of September 30, 2007, none of the Funds had a net capital loss carryforward available to offset future realized gains and thereby potentially reduce future taxable gains distributions.

For the year ended September 30, 2007, the components of distributable earnings on a tax basis (excluding unrealized appreciation (depreciation)) were as follows:

During the years ended September 30, 2007 and September 30, 2006, the tax character of distributions paid was as follows:

N/A – Not applicable as Fund commenced operations on October 2, 2006.

On September 30, 2007, the Funds had temporary book/tax differences in undistributed earnings that were primarily attributable to trustee deferred compensation expenses, passive foreign investment companies, foreign currency contracts and deferrals of capital losses on wash sales. Temporary differences will reverse over time. The Funds have permanent differences in book/tax undistributed earnings primarily attributable to currency gains and losses and equalization debits. Permanent differences have been in their respective component of the Analysis of Net Assets.

4. INVESTMENT TRANSACTIONS

For the year ended September 30, 2007, transactions in investment securities (excluding short term and U.S. Government securities) were as follows (in thousands):

Purchases at cost and proceeds (in thousands) from sales of long-term U.S. Government securities for the year ended September 30, 2007, were $5,500,340 and $4,485,228 respectively for Equity and Income.
