Item 1.01

Entry into a Material Definitive Agreement

On June 27, 2007, we entered into an accelerated share repurchase agreement (ASR) with Bank of America, N.A. Under the ASR, we agreed to purchase 7,500,000 shares of our common stock from Bank of America, N.A. at a price per share of $49.33 for a total of $370 million. We will fund the purchase with cash on hand. The company's outstanding shares used to calculate earnings per share will be reduced by the number of shares repurchased and now stands at approximately 104 million shares outstanding.

This transaction is subject to, among other things, a market price adjustment provision based upon the volume-weighted average market trading price (less a discount) of our common stock during the term of the ASR. If we are obligated to make an adjustment payment to Bank of America, N.A. under the ASR, we may elect to satisfy our obligation in cash or in shares of our common stock. This ASR was entered into pursuant to our previously announced stock repurchase program.
