Stock Repurchases

Stock Repurchases:

Our Board of Directors has authorized a total of $700.0 million towards the repurchase of shares of our common stock (collectively referred to as the "Share Repurchase Plans"). The Share Repurchase Plans authorize open market repurchase transactions and do not have an expiration date. There were no additional share repurchase authorizations in the first quarter of 2014. As of March 31, 2014, $246.2 million of shares may yet be repurchased under the Share Repurchase Plans.

We did not repurchase any shares under the Share Repurchase Plans in the first three months of 2014. However, we repurchased 0.1 million shares for $10.7 million for the three months ended March 31, 2014 from employees who surrendered their shares to satisfy minimum tax withholding obligations upon the exercise of long-term incentive awards.
