Stockholders' Equity Note [Abstract] |
Stock Repurchases | Stock Repurchases: Our Board of Directors has authorized a total of $2.5 billion to repurchase shares of our common stock (collectively referred to as the "Share Repurchase Plans"), including a $500 million share repurchase authorization in March 2018. Under this program, we may repurchase shares from time to time in open market transactions and in privately negotiated transactions based on business, market, applicable legal requirements and other considerations. The repurchase program does not require the repurchase of a specific number of shares and may be terminated at any time. As of March 31, 2019, $346 million of shares may be repurchased under the Share Repurchase Plans. We repurchased 0.4 million shares for $100.0 million from open market transactions during the first quarter of 2019. We also repurchased 0.1 million shares for $13.5 million during the three months ended March 31, 2019 from employees who surrendered shares to satisfy minimum tax withholding obligations upon the exercise of long-term incentive awards.
