Senior Secured Credit Facility [Member] | $350 Million Senior Secured Credit Facility [Member]
Condensed Consolidating Financial Statements [Line Items]
Debt instrument face amount							$ 350,000,000

[1] On July 21, 2015, the Company refinanced its existing $350 million senior secured credit facility ("Old Credit Facility") by entering into a new senior unsecured revolving credit agreement ("New Credit Facility"). As a result of this refinancing, certain guarantor subsidiaries under the Old Credit Facility have been released as a guarantor under the New Credit Facility. As a result, the following condensed consolidating financial statements for the prior year periods have been reclassified to reflect the current guarantors under the New Credit Facility.
