Supplementary Data Share Repurchase Program (Notes)

Stockholders' Equity Note [Abstract]

In February 2015, our Board of Directors (the "Board") authorized a new share repurchase program to repurchase from time to time up to $300.0, excluding fees, of our common stock, which was in addition to the remaining amount available to be repurchased from the $300.0 authorization made by the Board in February 2014.

We may effect such repurchases through open market purchases, trading plans established in accordance with SEC rules, derivative transactions or other means. We expect to continue to repurchase our common stock in future periods, although the timing and amount of the repurchases will depend on market conditions and other funding requirements.

The following table presents our share repurchase activity under our share repurchase programs for the six months ended June 30, 2015 and 2014.
