Stock Repurchase Activities

In February 2010, the Company’s Board of Directors (the “Board”) approved a stock repurchase program (the “2010 Stock Repurchase Program”) which authorized the Company to repurchase up to $1.0 billion of its common stock. This authorization was in addition to the stock repurchase program approved by the Board in March 2008 (the “2008 Stock Repurchase Program”), which also enabled the Company to repurchase up to $1.0 billion of the Company’s common stock.

The Company repurchased and retired approximately 17.5 million shares of its common stock at an average price of $30.93 per share for an aggregate purchase price of $541.2 million during year ended December 31, 2011 under its 2010 Stock Repurchase Program. The Company repurchased approximately 19.7 million shares of its common stock at an average price of $28.67 per share for a total purchase price of $563.5 million in the year ended December 31, 2010 under the two stock repurchase programs. There are no remaining authorized funds under the 2008 Stock Repurchase Program and $213.8 million remaining authorized funds under the 2010 Stock Repurchase Program as of December 31, 2011.

In addition to repurchases under the Company’s stock repurchase programs, there were also broker-transacted repurchases of common stock from the Company's employees in connection with net issuance of shares to satisfy tax withholding obligations for the vesting of certain RSUs and PSAs. There were broker-transacted repurchases of approximately 0.2 million shares of common stock at an average price of $35.98 per share for an aggregate purchase price of $7.4 million in connection with the net issuances during the year ended December 31, 2011. There were broker-transacted repurchases of approximately 0.1 million shares of common stock at an average price of $25.75 per share for an aggregate purchase price of $1.9 million in connection with the net issuances during the year ended December 31, 2010.

All shares of common stock repurchased under the Company’s 2008 and 2010 stock repurchase programs and from its employees in connection with net issuances have been retired. Future share repurchases under the Company’s 2010 Stock Repurchase Program will be subject to a review of the circumstances in place at that time and will be made from time to time in private transactions or open market purchases as permitted by securities laws and other legal requirements. This program may be discontinued at any time. See Note 17, Subsequent Events, for discussion of the Company's stock repurchase activity in 2012.
