Share Repurchases [Abstract]
Treasury Stock	Share Repurchases On August 23, 2021, our Board of Directors authorized a new $1.0 billion share repurchase program (the “2021 Repurchase Program”), replacing our 2015 Repurchase Program. The 2021 Repurchase Program allows the Company to repurchase shares of our Common Stock, through open market purchases, accelerated share repurchase arrangements, privately negotiated transactions or otherwise and has no set expiration date. In connection with this authorization, the remaining amount of $700 million authorized under 2015 Repurchase Program was terminated. During the quarter ended September 30, 2021, we repurchased 629,822 shares of Common Stock in the open market under the 2021 Repurchase Program for approximately $21.0 million. The extent to which we repurchase our shares and the timing of any such repurchases depend on a number of factors, including market and business conditions, the price of our shares, and corporate, regulatory and other considerations.
