Accounts Receivable Securitization	Jun. 30, 2014
Transfers and Servicing [Abstract]
Accounts Receivable Securitization	Accounts Receivable Securitization The company maintains an accounts receivable securitization program with a commitment size of $150.0 million, whereby transactions under the program are accounted for as sales in accordance with ASC Topic 860, “Transfers and Servicing.” Sales of trade receivables under the program are reflected as a reduction of accounts receivable in the accompanying Condensed Consolidated Balance Sheets and the proceeds received, including collections on the deferred purchase price notes, are included in cash flows from operating activities in the accompanying Condensed Consolidated Statements of Cash Flows. The company deems the interest rate risk related to the deferred purchase price notes to be de minimis, primarily due to the short average collection cycle of the related receivables (i.e., 60 days) as noted below. Trade accounts receivables sold to a third-party financial institution (“Purchaser”) and being serviced by the company totaled $136.9 million as of June 30, 2014 and $148.9 million at December 31, 2013. Due to an average collection cycle of less than 60 days for such accounts receivable as well as the company’s collection history, the fair value of the company’s deferred purchase price notes approximates book value. The fair value of the deferred purchase price notes recorded as of June 30, 2014 and December 31, 2013 was $79.8 million and $41.3 million, respectively, and is included in accounts receivable in the accompanying Condensed Consolidated Balance Sheets. The accounts receivable securitization program also contains customary affirmative and negative covenants. Among other restrictions, these covenants require the company to meet specified financial tests, which include a consolidated interest coverage ratio and a consolidated senior secured leverage ratio that are the same as the covenant ratios required per the New Senior Credit Facility. As of June 30, 2014, the company was in compliance with all affirmative and negative covenants inclusive of the financial covenants pertaining to the accounts receivable securitization program. Based on the company's current plans and outlook, management believes the company will be able to comply with these covenants during the subsequent twelve months.
