Stockholders' Equity

Stock Repurchases

On April 29, 2013, our Board of Directors approved a share repurchase program for up to $500 million of our outstanding shares of common stock. Approximately $295.9 million remained available for stock repurchases as of December 31, 2013 pursuant to our stock repurchase program. We repurchased 1.2 million shares for $19.7 million during the three months ended December 31, 2013 (including 0.1 million shares for $1.7 million that were repurchased, but not settled at December 31, 2013). Under the terms of the repurchase program, we expect to continue to repurchase shares from time to time through a variety of methods, which may include open market purchases, privately negotiated transactions, block trades, accelerated stock repurchase transactions, or any combination of such methods. The timing and the amount of any purchases will be determined by management based on an evaluation of market conditions, capital allocation alternatives, and other factors. The share repurchase program does not require us to acquire any specific number of shares and may be modified, suspended, extended or terminated by us at any time without prior notice.
