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. The Company's goal for the share repurchase program is to offset the dilution created by its employee equity compensation programs and provide the flexibility to return capital to shareholders as business and market conditions warrant. During the six months ended June 30, 2017, the Company repurchased 3.1 million shares of its common stock for $177.6 million.
