Stockholders' Equity Note [Abstract]

Stockholders’ Equity

Share Repurchase Program

In February 2016, the Board of Directors authorized a $1.0 billion repurchase program effective from February 2016 through December 2018. In March 2018, the Company announced that its Board had increased its share repurchase authorization by $416.7 million, such that the amount that is authorized and available for repurchase in 2018 is $750.0 million. The Company's goal for the share repurchase program is to return capital to shareholders, as business and market conditions warrant, and to offset the dilution created by its employee equity compensation programs.

During the three months ended March 31, 2018, the Company repurchased 0.3 million shares of its common stock for $19.8 million.
