Equity [Abstract]  
Stockholders' Equity Note Disclosure [Text Block] Since the inception of the Company's stock repurchase plan in 2004 through September 30, 2020, the Company's Board of Directors has authorized the purchase of $1.1 billion of the Company's common stock. As of September 30, 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. 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. 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. In mid-March 2020, to reduce capital outflows and preserve capital, the Company suspended share repurchases.
