Equity [Abstract] |
Stockholders' Equity | Stockholders' Equity On February 4, 2016, the Company's Board of Directors approved a stock repurchase program (the "Program") under which the Company may purchase up to an aggregate of $500 million of its common stock over the following 18 month period. On July 27, 2017, the Company's Board of Directors authorized an increase in the size of the Program by an additional $250 million and an extension of the Program by an additional 18 months. On November 1, 2017, the Company announced that its Board of Directors had authorized an increase in the size of the Program by an additional $350 million, resulting in total aggregate repurchases authorized under the Program of $1.1 billion. With the increase and giving effect to the Company's $678.4 million of previous repurchases, the Company may repurchase up to $421.6 million in shares of its common stock at any time prior to February 1, 2019. Any stock repurchases may be made at times and in such amounts as deemed appropriate. The timing and amount of stock repurchases, if any, will depend on a variety of factors including the stock price, market conditions, corporate and regulatory requirements, and any additional constraints related to material inside information the Company may possess. Any repurchases have been and are expected to be funded by a combination of available cash flow from the business, working capital and debt. Since the beginning of the Program, 4,556,729 shares for an aggregate purchase price of $678.4 million have been repurchased. There were 442,625 shares totaling $88.3 million repurchased under the Program during the three months ended March 31, 2018.
