Equity [Abstract]  
Stockholders' Equity Note Disclosure [Text Block] Since the inception of the Company's stock repurchase plan in 2004 through March 31, 2020, the Company's Board of Directors has authorized the purchase of $1.1 billion of the Company's common stock. As of March 31, 2020, the Company had repurchased 26.8 million shares under this program at an aggregate purchase price of $1,017.8 million. Shares repurchased generally settle subsequent to the trade date. During the three months ended March 31, 2020, the Company repurchased an aggregate of $132.9 million of common stock under the stock repurchase plan authorized by the Company's Board of Directors and a pre-established written trading plan. Shares of the Company's common stock may be repurchased in the open market or through privately negotiated transactions, subject to market conditions. The repurchase program does not obligate the Company to acquire any specific number of shares or to acquire shares over any specified period of time. In mid-March 2020 to reduce capital outflows and preserve capital, the Company suspended share repurchases and the Company's Board of Directors suspended the quarterly dividend.
