The graph and table do not reflect the deduction of taxes that a shareholder would pay on fund distributions or the redemption of fund shares.
Expense Ratio as of 9/30/06 was 1.05%.
The performance data quoted represents past performance. The above performance information for the Fund does not reflect the imposition of a 2% redemption fee on shares held for 90 days or less to deter market timers. If reflected, the fee would reduce the performance quoted. Past performance does not guarantee future results. The investment return and principal value 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. Average annual total return measures annualized change, while total return measures aggregate change.

* Not annualized

The Oakmark Fund increased in value by 6% during the quarter. Since the Fund was flat in the first calendar quarter, the year-to-date increase is also 6%. The strength in the stock market and our portfolio was consistent with strong corporate earnings and continued heavy share repurchase and acquisition activity. For the quarter, sixteen of our stocks achieved double-digit gains compared to only two suffering double-digit losses. Our two largest positive contributors, Texas Instruments and Intel, each up 25%, benefited from better than expected earnings. Both stocks continue to sell at less than our estimate of business value, so despite the price increase, we still find both attractive. During the quarter we added three new positions and eliminated two. Our purchase of Best Buy is described below. We also added positions in Capital One Financial (COF - $78) and Federal Express (FDX - $111), which are explained on our website. First Data was sold after KKR announced their intent to purchase the company. Echostar was sold because the stock had performed well and was approaching our estimate of business value.

Best-Buy (BBY - $47)

Best Buy is the world’s largest retailer of consumer electronics. With over 1100 stores and sales approaching $40 billion, Best Buy has not only the largest market share in the U.S. but has more than twice the share of the number two competitor. And with their market share still under 25%, most of the market remains in the hands of less efficient competitors. Over the past five years, Best Buy has grown per-share sales and earnings at 12% and 18% respectively. We expect the consumer electronics category to continue to grow faster than other retail categories, and we also expect Best Buy’s aggressive expansion to increase their market share. Despite the track record and the long-term opportunity created by their competitive advantages, the stock fell from $60 last year to $44. Subtracting their $6 per share of excess cash (and its related interest income) Best Buy stock now sells at only 14 times expected earnings. The company has been an aggressive acquirer of their own stock so far this year, and it just announced plans to buy back an additional 25% of their outstanding shares. We believe that Best Buy is a superior business and therefore believe that investors will again reward it with a superior multiple.
