Subsequent Events [Abstract]
Subsequent Events	Subsequent Events On July 21, 2015, the Company refinanced its existing $350 million senior secured credit facility, comprised of a $200 million revolving credit tranche and a $150 million term loan tranche by entering into a new senior unsecured revolving credit agreement (“Credit Agreement”), with Deutsche Bank AG New York Branch, as administrative agent. The Credit Agreement provides for a $450 million unsecured revolving credit facility (the “New Revolver”) with a final maturity date of July 21, 2020, subject to optional one-year extensions that can be requested by the Company prior to each of the first, second and third anniversaries of the closing date of the New Revolver. The effectiveness of any such extensions is subject to the consent of the lenders under the Credit Agreement and certain customary conditions. Up to $35 million of borrowings under the New Revolver may be used for alternative currency loans and up to $15 million of borrowings under the New Revolver may be used for swing line loans. The New Revolver is unconditionally guaranteed, jointly and severally, by certain of the Company’s domestic subsidiaries, which are considered restricted subsidiaries under the Credit Agreement. The subsidiary guarantors currently include all subsidiaries that guarantee the obligations under the Company's Indenture governing the terms of its 5.75% senior notes due 2020 and its 5.70% senior notes due 2020. If the Company achieves and maintains an Investment Grade Rating, as defined in the Credit Agreement, then the subsidiary guarantees will at the election of the Company be released and the New Revolver will not be guaranteed. The Company may at any time prior to the final maturity date increase the amount of the New Revolver by up to an additional $150 million to the extent that any one or more lenders commit to being a lender for the additional amount and certain other customary conditions are met. The Company currently may elect to have borrowings under the New Revolver bear interest at a rate equal to (i) LIBOR plus a margin ranging from 135 to 175 basis points based on the Company’s total leverage ratio or (ii) a base rate plus a margin ranging from 35 to 75 basis points based on the Company’s total leverage ratio. If the Company achieves an Investment Grade Rating, then the Company may elect to use a different, ratings-based, pricing grid set forth in the Credit Agreement. The Credit Agreement requires the Company to pay a fee on the undrawn portion of the New Revolver, calculated on the basis of the average daily unused amount of the New Revolver multiplied by 0.20% per annum. If the Company achieves an Investment Grade Rating and it elects to use the ratings-based pricing grid set forth in the Credit Agreement, then the Company will be required to pay a fee on the total commitments under the New Revolver, calculated on the basis of the actual daily amount of the commitments under the New Revolver (regardless of usage) times a percentage per annum ranging from 0.10% to 0.25% (depending on the Company’s senior unsecured long-term debt rating). The Credit Agreement requires that the Company and its restricted subsidiaries comply with various covenants, including with respect to restrictions on liens, incurring indebtedness, making investments and effecting mergers and/or asset sales. With respect to dividends, the Company may not declare or make any payment if there is an existing event of default or if the payment would create an event of default. In addition, if the Company’s total leverage ratio exceeds 4.0 to 1.0, the Company is generally restricted from paying aggregate dividends in excess of $50 million in any calendar year. The Credit Agreement imposes financial maintenance covenants requiring the Company to maintain a total leverage ratio of not more than 4.5 to 1.0 and a consolidated fixed charge coverage ratio of at least 2.5 to 1.0. If the Company achieves and maintains an Investment Grade Rating, then the Company will not need to comply with the consolidated fixed charge coverage ratio covenant. The Credit Agreement includes customary events of default, the occurrence of which, following any applicable cure period, would permit the lenders to, among other things, declare the principal, accrued interest and other obligations of the Company under the Credit Agreement to be immediately due and payable. The proceeds of the New Revolver are expected to be used for general corporate purposes, including working capital, debt repayment, stock repurchases, dividends, investments and other permitted uses set forth in the Credit Agreement.
