Subsequent Events [Abstract]
Subsequent Events	SUBSEQUENT EVENTS On February 17, 2016, we entered into an amendment to the Fourth Amended and Restated Credit Agreement which amends certain provisions of the credit agreement including extending the maturity of both the Senior Secured Credit Facility and the Term Loan (collectively the "Facilities") through February 2021, coterminous with one another. The maximum aggregate commitment for the Senior Secured Credit Facility remains at $500 million and the unamortized Term Loan of $188.75 million was refinanced as part of this amendment and restatement. On February 24, 2016, our Board of Directors authorized the repurchase of up to $150.0 million of our common stock in a stock repurchase program. The new program replaced the prior $150.0 million plan which was in effect at December 31, 2015 and which had unused authorization of $11.9 million. Repurchases may be made at management’s discretion from time to time on the open market (either with or without a 10b5-1 plan) or through privately negotiated transactions. The repurchase program has no time limit and may be suspended for periods or discontinued at any time.
