10. Stockholders' Equity

In January 2012, the Company commenced a "modified Dutch auction" self-tender offer (the "Offer") to purchase up to $500 in value of its common stock. In March 2012, pursuant to the terms of the Offer, the Company repurchased approximately 12.1 million shares of its common stock for a total purchase price of approximately $435 or $36.00 per share. The repurchase of shares of common stock under the Offer was made pursuant to the Company's existing stock repurchase program, pursuant to which the Company is authorized to repurchase up to $500 aggregate amount of outstanding shares of common stock at prevailing market prices or in privately-negotiated transactions.

During the three months ended March 31, 2012 and 2011, the Company repurchased approximately 12.1 million and 0.7 million shares, respectively, of its common stock at a per share average price of $36.00 and $33.49, respectively.
