Long-term Debt [Text Block]	Note 6. Long-Term Debt The Company entered into a Third Amended and Restated Business Loan and Security Agreement (the “Credit Facility”) on March 14, 2012, as amended May 29, 2012 and July 31, 2013, with a syndication of eleven commercial banks to allow for borrowings of up to $500.0 million for a period of five years (maturing March 14, 2017) under a revolving line of credit. The Credit Facility amends and restates the Company’s previous agreement entered into on February 20, 2008, which had allowed for borrowings of up to $350.0 million. The Credit Facility provides for borrowings of up to $400.0 million without a borrowing base requirement, subject to limitations based upon certain financial, performance-based calculations. The Credit Facility also provides for an “accordion feature,” which permits additional revolving credit commitments of up to $100.0 million, subject to lenders’ approval. The Company incurred approximately $2.0 million in additional debt issuance costs related to amending the Credit Facility, which are amortized over the term of the agreement. The Credit Facility is collateralized by substantially all of the assets of the Company and requires that the Company remain in compliance with certain financial and non-financial covenants. The financial covenants, as defined in the Credit Facility, require, among other things, that the Company maintain, on a consolidated basis for each quarter, a fixed charge coverage ratio of not less than 1.25 to 1.00 and a leverage ratio of not more than 3.75 to 1.00. As of September 30, 2013, the Company was in compliance with its covenants under the Credit Facility. The Company has the ability to borrow funds under its Credit Facility at interest rates based on both LIBOR and prime rates, at its discretion, plus their applicable margins. Interest rates on debt outstanding ranged from 1.43% to 1.46% for the first nine months of 2013. As of September 30, 2013, the Company had $64.1 million in long-term debt outstanding, $3.0 million in outstanding letters of credit, and unused borrowing capacity of $332.9 million under the Credit Facility. Available borrowings under the Credit Facility, that are based on earnings and leverage ratios and exclude the accordion feature, were $295.6 million.
