Debt Disclosure [Abstract]
Long-Term Indebtedness	LONG-TERM INDEBTEDNESS At March 31, 2015, the Company had no outstanding borrowings on its line of credit. At March 31, 2014 and December 31, 2014, the Company had $10.0 million and $15.7 million, respectively, of outstanding borrowings on its line of credit. On February 24, 2014, the Company entered into a $75.0 million line of credit (the “Credit Agreement”) with JPMorgan Chase Bank, N.A. and Wells Fargo Bank, N.A. On March 3, 2015, in accordance with the terms of the Credit Agreement, the Company increased its line of credit by $25.0 million to $100.0 million. Interest on borrowings under the line of credit is designated from time to time by the Company as either (i) the Prime Rate, minus a rate ranging from 0.75 percent to 1.0 percent (minus 1.0 percent at March 31, 2015), but not less than 1.5 percent, or (ii) LIBOR, plus additional interest ranging from 1.75 percent to 2.0 percent (plus 1.75 percent at March 31, 2015) depending on the Company’s performance and financial condition. The Credit Agreement expires on January 1, 2019. At March 31, 2015, the Company had $2.7 million in outstanding letters of credit under the line of credit. Availability under the Company’s line of credit was $97.3 million at March 31, 2015. On February 24, 2014, the Company also entered into a $150.0 million “shelf-loan” facility with Prudential Investment Management, Inc. and its affiliates (“Prudential”). The facility provides for Prudential to consider purchasing, at the Company’s request, in one or a series of transactions, Senior Promissory Notes of the Company in the aggregate principal amount of up to $150.0 million, to mature no more than twelve years after the date of original issue of each Senior Promissory Note. Prudential has no obligation to purchase the Senior Promissory Notes. Interest payable on the Senior Promissory Notes will be at rates determined by Prudential within five business days after the Company issues a request to Prudential. This facility expires February 24, 2017. On March 20, 2015, the Company issued $50.0 million of Senior Promissory Notes to Prudential for a term of five years, at a fixed interest rate of 3.35 percent per annum, payable quarterly in arrears, of which the entire amount was outstanding at March 31, 2015. Availability under the Company's “shelf-loan” facility, subject to the approval of Prudential, was $100.0 million at March 31, 2015. Borrowings under both the line of credit and the “shelf-loan” facility are secured on a pari-passu basis by first priority liens on the capital stock or other equity interests of each of the Company’s direct and indirect subsidiaries. Pursuant to the Credit Agreement and “shelf-loan” facility, at March 31, 2015, the Company was required to maintain minimum interest and fixed charge coverages, and to meet certain other financial requirements. At March 31, 2015, the Company was in compliance with all such requirements, and expects to remain in compliance for the next twelve months. Both the line of credit pursuant to the Credit Agreement and the “shelf-loan” facility are subject to a maximum leverage ratio covenant which limits the amount of consolidated outstanding indebtedness to 2.5 times the trailing twelve-month EBITDA, as defined. This limitation did not impact the Company’s borrowing availability at March 31, 2015. The remaining availability under these facilities was $197.3 million at March 31, 2015. The Company believes the availability under the line of credit and “shelf-loan” facility is more than adequate to finance the Company’s anticipated cash requirements for the next twelve months. The Company is currently negotiating a one-year extension of its line of credit and “shelf-loan” facility as well as an increase in its line of credit to $125.0 million. The Company is extending these arrangements now to meet the anticipated growth of the Company and to add the ability to borrow in international locations and currencies.
