Investing in small and mid-cap stocks is more risky and more volatile than investing in large cap stocks. The Fund was rated two stars among 378, three stars among 310 and five stars among 117 domestic mid-cap blend funds for the three-, five- and ten-year periods ended 12/31/06, respectively. These ratings may change monthly. For each fund with at least a three-year history, Morningstar calculates a Morningstar RatingTM based on a Morningstar Risk-Adjusted Return measure that accounts for variation in a fund’s monthly performance (including the effects of sales charges, loads and redemption fees), placing more emphasis on downward variations and rewarding consistent performance. The top 10% of funds in an investment category receive five stars; the next 22.5% receive four stars; the next 35% receive three stars; the next 22.5% receive two stars and the bottom 10% receive one star. Morningstar does not guarantee the accuracy of this information. 1

The quarter began with the Russell benchmarks on a tear—delivering nearly a year’s worth of performance in just two months. Investors were riding high on the second longest rally since 1929, now at four years and counting. Then in December the Russell Indices faltered as slower-thanexpected economic growth combined with higher-than-expected inflation proved that the so-called Goldilocks economy is not “just right.” However, Ariel’s portfolios of quality companies possessing trusted franchises, predictable earnings and solid financials largely dodged the December blues and delivered robust results for the month. By quarter-end, Ariel Fund produced a solid return, albeit lower than the benchmarks. During the quarter, several holdings posted impressive returns. Notably, Markel Corp.’s shares rose due to strong investment results and a benign hurricane season. Additionally, Interpublic Group of Cos., Inc.’s shares surged due to several sizeable wins giving its turnaround efforts added momentum. Some of the quarter’s gains were dampened by weaker performance of a few portfolio holdings. Specifically, Tribune Co. slid as bids for purchasing the company came in below expectations. We believe the company is pursuing all options to unlock shareholder value and expect that a favorable resolution will be reached by the end of March. Secondly, Anixter International Inc.’s stock declined as the price of copper fell substantially. Our independent verification shows that Anixter is much less exposed to copper prices than the market anticipates. During the period, we exited long-time holding American Greetings Corp. on recent strength, while our position in Radio One, Inc. was eliminated to pursue more compelling investment opportunities. Finally, we sold out of Valassis Communications, Inc. after the stock rose on the announcement that it had settled its dispute with ADVO, Inc. and will continue with its planned acquisition. No new positions were added during the quarter.

Ariel’s industry concentration helps to add value in areas we know well.

The market rally has held up longer than we ever would have imagined, and we believe a correction is inevitable—we are anticipating at least a ten percent drop in 2007. In our view, earnings expectations are overly optimistic. As the economy starts to decelerate, corporate profits naturally will do the same, bringing stock prices down with them. We believe this is a time to be both cautious and conservative. So we are sticking with the slow-and-steady-eddies which we believe have sturdy franchises, deep moats and robust cash flows that enable them to hold firm during periods of slowing economic growth.
