THE OAKMARK FUNDS

Notes to Schedules of Investments (Unaudited)

1.  SIGNIFICANT ACCOUNTING POLICIES

Organization

Harris Associates Investment Trust (the “Trust”) is registered under the Investment Company Act of 1940, as amended (the “1940 Act”), as an open-end management investment company organized as a Massachusetts business trust on February 1, 1991 and accordingly follows the investment company accounting and reporting guidance of the Financial Accounting Standards Board (“FASB”) Accounting Standard Codification Topic 946 Financial Services - Investment Companies. The Trust consists of the following series (each individually referred to as “a Fund” or collectively as “the Funds”): Oakmark Fund (“Oakmark”), Oakmark Select Fund (“Select”), Oakmark Equity and Income Fund (“Equity and Income”), Oakmark Global Fund (“Global”), Oakmark Global Select Fund (“Global Select”), Oakmark International Fund (“International”), and Oakmark International Small Cap Fund (“Int’l Small Cap”).  Each Fund, other than Select and Global Select, is diversified in accordance with the 1940 Act.

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 or the official closing 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 System are valued at the NASDAQ Official Closing Price (“NOCP”), or lacking an NOCP, at the most recent bid quotation on the NASDAQ National Market System.  Equity securities principally traded on securities exchanges outside the United States are valued, 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 are based on a pricing composite as of the close of the regular trading hours on the appropriate exchange or other designated time. Each long-term debt instrument is valued at the latest bid quotation or an evaluated price provided by an independent pricing service. The pricing service may use standard inputs such as benchmark yields, reported trades, broker/dealer quotes, issuer spreads, two-sided markets, benchmark securities, bids offers, and reference data, including market research publications.  For certain security types, additional inputs may be used or some of the standard inputs may not be applicable.  Additionally, the pricing service monitors market indicators and industry and economic events, which may serve as a trigger to gather and possibly use additional market data. Each short-term debt instrument (i.e., debt instruments whose maturities or expiration dates at the time of acquisition are one year or less) or money market instrument maturing in 61 days or more from the date of valuation is valued at the latest bid quotation or an evaluated price provided by an independent pricing service. Each short-term instrument maturing in 60 days or less from the date of valuation is valued at amortized cost, which approximates market value. Options are valued at the mean of the most recent bid and asked quotations.

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 value, determined by or under the direction of the pricing committee authorized by the Board of Trustees.  A significant event may include the performance of U.S. markets since the close of foreign markets.  The Funds may use a systematic fair valuation model provided by an independent pricing service to value foreign securities in order to adjust local closing prices for information or events that may occur between the close of certain foreign exchanges and the close of the NYSE.

Fair value measurement

Various inputs are used in determining the value of each Fund’s investments. These inputs are prioritized into three broad levels as follows:

Level 1 — quoted prices in active markets for identical securities

Level 2 — other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, credit risk and others)

Level 3 — significant unobservable inputs (including the assumptions of Harris Associates L.P. (the “Adviser”) in determining the fair value of investments)

Observable inputs are those based on market data obtained from independent sources, and unobservable inputs reflect the Adviser’s own assumptions based on the best information available.  The input levels are not necessarily an indication of risk or liquidity associated with investing in those securities.

The Funds recognize transfers between level 1 and level 2 at the end of the reporting cycle. At December 31, 2017, there were no transfers between level 1 and level 2 securities.

The following is a summary of the inputs used as of December 31, 2017 in valuing each Fund’s assets and liabilities. Except for the industries or investment types separately stated below, the total amounts for common stocks, fixed-income and short-term investments in the table below are presented by industry or investment type in each Fund’s Schedule of Investments. Information on forward foreign currency contracts is presented in each Fund’s Schedule of Investments.

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

Forward foreign currency contracts are agreements to exchange one currency for another at a future date and at a specified price.  Each of the Funds’ transactions in forward foreign currency contracts were used for transaction or portfolio hedging.  The contractual amounts of forward foreign currency 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 and could exceed the net unrealized value shown in the tables below.  Risks arise from the possible inability of counterparties to meet the terms of their contracts and from movements in currency values.  Forward foreign currency contracts are valued at the current day’s interpolated foreign exchange rates.  Unrealized gain or loss on the contracts as measured by the difference between the forward foreign exchange rates at the dates of entry into the contracts and the forward rates at the end of the period.

At December 31, 2017 Global, Global Select, International and Int’l Small Cap held non-collateralized forward foreign currency contracts, which are considered derivative instruments, each of whose counterparty is State Street Bank and Trust Company (“State Street”), are listed in the Fund’s Schedule of Investments.

During the period ended December 31, 2017, the Funds did not have any forward foreign currency contracts opened and any forward currency contracts settled.

Short sales

Each Fund may sell a security it does not own in anticipation of a decline in the fair value of that security. When a 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 the short sale. Each Fund may sell shares of when-issued securities. Typically, a Fund sells when-issued securities when a company announces a spin-off or re-organization, and the post-spin-off or post-re-organization shares begin trading on a when-issued basis prior to the effective date of the corporate action. A sale of a when-issued security is treated as a short sale for accounting purposes. After the effective date, when shares of the new company are received, any shares sold on a when-issued basis will be delivered to the counterparty. At December 31, 2017 none of the Funds had short sales.

When-issued or delayed-delivery securities

Each Fund may purchase securities on a when-issued or delayed-delivery basis. Although the payment and interest terms of these securities are established at the time a Fund enters into the commitment, the securities may be delivered and paid for a month or more after the date of purchase, when their value may have changed. A Fund makes such commitments only with the intention of actually acquiring the securities, but may sell the securities before the settlement date if the Adviser deems it advisable for investment reasons. At December 31, 2017 none of the Funds held when-issued securities.

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 fair 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. As the writer of a covered call option on a security, a Fund foregoes, during the option’s life, the opportunity to profit from increases in the market value of the security covering the call option above the sum of the premium and the exercise price of the call. 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 fair value. Options written by the Fund do not give rise to counterparty credit risk, as they obligate the Fund, 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 fair 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, in the instances of OTC derivatives, the failure of the counterparty to honor its obligation under the contract.

During the period ended December 31, 2017, there are no written option outstanding.

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 Funds’ custodian 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 102% of the repurchase price, including interest. The Adviser is responsible for determining that the value of the collateral is at all times at least equal to 102% 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. At December 31, 2017 all of the Funds held repurchase agreements.

Security lending

Each Fund may lend its portfolio securities to broker-dealers and banks. Any such loan must be continuously secured by collateral in cash, cash equivalents or U.S. Treasury or agency securities maintained on a current basis in an amount at least equal to the fair value of the securities loaned by a Fund.  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 has the right to call the loan and attempt to obtain the securities loaned at any time on notice of not more than five business days. 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. There could also 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.
