Long-Term Indebtedness	Jun. 30, 2014
Debt Disclosure [Abstract]
Long-Term Indebtedness	LONG-TERM INDEBTEDNESS At June 30, 2014, the Company had $22.3 million of outstanding borrowings on its line of credit at a rate of 1.9 percent to 2.25 percent. The Company had no debt outstanding at June 30, 2013 or December 31, 2013. 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. (collectively, the “Lenders”), amending the Company's previous $50.0 million line of credit that was scheduled to expire on January 1, 2016. The maximum borrowings under the Company’s new line of credit can be increased by $25.0 million upon approval of the Lenders. Interest on borrowings under the new 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 June 30, 2014), 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 June 30, 2014) depending on the Company’s performance and financial condition. The Credit Agreement expires on January 1, 2019. At June 30, 2014, the Company had $2.2 million in outstanding letters of credit under the line of credit. Availability under the Company’s new line of credit was $50.5 million at June 30, 2014. Simultaneously, the Company also entered into a $150.0 million “shelf-loan” facility with Prudential Investment Management, Inc. and its affiliates (“Prudential”), amending the Company's previous $150.0 million "shelf-loan" facility with Prudential. The new 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. At June 30, 2014, there were no Senior Promissory Notes outstanding. This new facility expires on February 24, 2017. 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 June 30, 2014 the Company was required to maintain minimum interest and fixed charge coverages, and to meet certain other financial requirements. At June 30, 2014, 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 June 30, 2014. The remaining availability under these facilities was $200.5 million at June 30, 2014. The Company believes the availability under the amended line of credit and "shelf-loan" facility is more than adequate to finance the Company’s anticipated cash requirements for the next twelve months.
