Total return includes change in share prices and in each case includes reinvestment of any dividends and capital distributions. Total return is not annualized.

The Oakmark Equity and Income Fund invests in medium- and lower-quality debt securities that have higher yield potential but present greater investment and credit risk than higher-quality securities. These risks may result in greater share price volatility. An economic downturn could severely disrupt the market in medium or lower grade debt securities and adversely affect the value of outstanding bonds and the ability of the issuers to repay principal and interest.

Investing in foreign securities presents risks that in some way may be greater than in U.S. investments. Those risks include: currency fluctuation; different regulation, accounting standards, trading practices and levels of available information; generally higher transaction costs; and political risks.

Because The Oakmark Select and Oakmark Global Select Funds are non-diversified, the performance of each holding will have a greater impact on the Funds' total return, and may make the Funds' returns more volatile than a more diversified fund.

The stocks of smaller companies often involve more risk than the stocks of larger companies. Stocks of small companies tend to be more volatile and have a smaller public market than stocks of larger companies. Small companies may have a shorter history of operations than larger companies, may not have as great an ability to raise additional capital and may have a less diversified product line, making them more susceptible to market pressure.
