Debt Disclosure [Abstract]
Debt	Debt On January 19, 2010, we entered into a four-year revolving credit and term loan agreement (the “2010 Credit Agreement”) with SunTrust Bank (“SunTrust”). Subsequent modifications of the 2010 Credit Agreement were entered into with SunTrust. Most recently, on December 23, 2014, we entered into an amended and restated revolving credit agreement (the “Credit Facility”) with SunTrust. The Credit Facility is guaranteed by the Company and all of its material domestic subsidiaries and secured by substantially all of the assets of the Company. The amount available for borrowing under the Credit Facility is $20.0 million, and as of June 30, 2016 we had no outstanding borrowings. With the Credit Facility provision of a fixed applicable margin of 1.75% plus a specified index rate based on one-month LIBOR, the interest rate that would have applied at June 30, 2016 had any borrowings been outstanding was approximately 2.21%. We also must pay a commitment fee of 0.25% per annum, payable quarterly, on the unused portion of the Credit Facility. The Credit Facility includes customary affirmative, negative, and financial covenants binding on the Company, including delivery of financial statements and other reports, maintenance of existence, and transactions with affiliates. The negative covenants limit the ability of the Company, among other things, to incur debt, incur liens, make investments, sell assets or declare or pay dividends on its capital stock. The financial covenants included in the Credit Facility, among other things, limit the amount of capital expenditures the Company can make, set forth maximum leverage and net funded debt ratios for the Company and a minimum fixed charge coverage ratio, and also require the Company to maintain minimum consolidated earnings before interest, taxes, depreciation and amortization. In addition, the Credit Facility includes customary events of default. The Company was in compliance with the covenants in its Credit Facility as of June 30, 2016.
