The discussion of investments and investment strategy of the funds represents the investments of the funds and the views of fund managers and Harris Associates L.P., the funds' investment adviser, at the time of this article, and are subject to change without notice.

Past performance is no guarantee of future results. Investment return and principal value will fluctuate so that shares, when redeemed, may be worth more or less than original cost.

Investing in value stocks presents the risk that value stocks may fall out of favor with investors and underperform growth stocks during given periods.

Because the Oakmark Select Fund is non-diversified, the performance of each holding will have a greater impact on the Fund's total return, and may make the Fund's return more volatile than a more diversified fund.

Investing in foreign securities represents risks which 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.

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.

The Oakmark Equity and Income Fund invests in medium and lower-quality debt securities which have higher yield potential but present greater investment and credit risk than higher-quality securities.
