Treasury Stock

 

In May 2010, our Board of Directors approved the purchase of up to $300.0 million of our common stock, and cancelled $0.7 million remaining under our original $100.0 million authorization approved in 2008. On March 10, 2011, the Board approved a new authorization for $300.0 million and cancelled $265.3 million remaining under the previous authorization. This plan was exhausted in September and, on September 23, 2011, the Board approved purchases of an additional $300.0 million (the Plan). In 2011, we purchased 12.6 million shares of our common stock in the open market for a total cost of $373.6 million and a weighted-average cost of $29.55 per share, of which $73.6 million, or 2.8 million shares, were purchased under the Plan. In 2010, we purchased 1.3 million shares of our common stock in the open market for a total cost of $35.1 million and a weighted-average cost of $26.99 per share.
