Stock Repurchases

Stock Repurchases:

In 2008, our Board of Directors approved a $300.0 million share repurchase plan authorizing the repurchase of shares of our common stock through open market purchases (the “2008 Share Repurchase Plan”). In December 2011, our Board of Directors increased the 2008 Share Repurchase Plan by $100 million. For the three and nine months ended September 30, 2012, we repurchased 0.8 million shares of our common stock under the 2008 Share Repurchase Plan. These repurchased and surrendered shares are included in Treasury Stock. The approximate dollar value of shares that may yet be repurchased under the 2008 Share Repurchase Program is $86.3 million.
