Performance data quoted represents past performance. Past performance does not guarantee future results. All performance assumes the reinvestment of dividends and capital gains. The investment return and principal value of an investment will fluctuate so that an investor's shares, when redeemed, may be worth more or less than their original cost. Current performance may be lower or higher than the performance data quoted.

**Performance information for the Institutional Class prior to that date reflects the actual performance of the Fund's Investor Class (and uses the actual expenses of the Fund's Investor Class, for such period of time), without any adjustments. For any such period of time, the performance of the Fund's Institutional Class would have been substantially similar to, yet higher than, the performance of the Fund's Investor Class, because the shares of both classes are invested in the same portfolio of securities, but the classes bear different expenses, which are primarily differences in distribution and service fees.

Investing in equity stocks is risky and subject to the volatility of the markets. Investing in small- and mid-cap stocks is more risky and volatile than investing in large-cap stocks. The intrinsic value of the stocks in which the Fund invests may never be recognized by the broader market. Ariel Fund and Ariel Appreciation Fund often invest a significant portion of their assets in companies within the financial services and consumer discretionary sectors and their performance may suffer if these sectors underperform the overall stock market. Ariel Focus Fund is a non-diversified fund and therefore may be subject to greater volatility than a more diversified investment. Investments in foreign securities may underperform and may be more volatile than comparable U.S. stocks because of the risks involving foreign economies and markets, foreign political systems, foreign regulatory standards, foreign currencies and taxes. The use of currency derivatives and ETFs may increase investment losses and expenses and create more volatility. Investments in emerging and developing markets present additional risks, such as difficulties in selling on a timely basis and at an acceptable price.

Average Annual Total Return for Ariel Fund and Ariel Appreciation Fund does not reflect a maximum 4.75% sales load charged prior to 07/15/94.
