Debt Disclosure [Abstract]
Debt	DEBT On January 19, 2010, we entered into a four-year revolving credit and term loan agreement with SunTrust Bank (“SunTrust”). The SunTrust credit facility initially consisted of a $15.0 million committed revolving credit facility and a $15.0 million term loan. The SunTrust term loan required quarterly principal payments of $0.8 million beginning in March 2010, and a final principal payment of $3.0 million due in January 2014 that we paid in December 2013. There have been no borrowings under the revolving credit portion of the SunTrust credit facility. The SunTrust 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. Prior to the January 2014 amendment to the SunTrust credit facility described below, amounts available under the SunTrust revolver were based on eligible accounts receivable and other factors. Interest on both the revolver and term loan was payable monthly and accrued at an index rate using the one-month LIBOR rate, plus an applicable margin as determined by the loan agreement. The applicable interest rate margin varied from 2.25% per annum to 3.5% per annum, dependent on our consolidated leverage ratio, and was determined in accordance with a pricing grid under the SunTrust loan agreement. The applicable margin was 2.25% and the interest rate was approximately 2.43% at December 31, 2013. We also paid a commitment fee of 0.5% per annum, payable quarterly, on the unused portion of the $15.0 million SunTrust revolving credit facility. The weighted-average interest rate on term loan balances outstanding under the SunTrust credit facility during 2013, including fees, was 4.1%. We made mandatory principal payments on the SunTrust term loan totaling $3.0 million and the final principal payment of $3.0 million during the year ended December 31, 2013. The SunTrust 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 SunTrust 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 SunTrust credit facility includes customary events of default. On January 17, 2014, we entered into an amendment of the SunTrust credit facility that increased the committed revolving credit facility from $15.0 million to $25.0 million, lowered the applicable margin to a fixed rate of 1.75%, eliminated the provision limiting availability under the revolving credit facility based on eligible accounts receivable and extended the scheduled maturity of the revolving credit facility to January 16, 2015 (subject to earlier termination as provided therein). We also paid a commitment fee of 0.5% per annum, payable quarterly, on the unused portion of the SunTrust revolving credit facility through the amendment date below. On December 23, 2014, we entered into an amendment of the SunTrust credit facility that reduced the committed revolving credit facility from $25.0 million to $20.0 million. The credit facility bears interest at a rate per annum comprised of a specified index rate based on one-month LIBOR, plus an applicable margin (1.75% per annum). The index rate is determined as of the first business day of each calendar month. With the provision of a fixed applicable margin of 1.75% per the amendment of the SunTrust credit facility, the interest rate that would have applied at December 31, 2015, had any borrowings been outstanding, was approximately 1.99%. The credit facility includes two financial covenants (a maximum leverage ratio and a minimum fixed charge coverage ratio) that apply only if we have borrowings under the credit facility that arise or remain outstanding during the final 30 calendar days of any fiscal quarter. These financial covenants also will be tested, on a modified pro forma basis, in connection with each new borrowing under the credit facility. This amendment also extended the scheduled maturity of the revolving credit facility to December 23, 2017 and lowered the commitment fee to 0.25% per annum, payable quarterly, on the unused portion of the revolving credit facility. The weighted-average interest rate for the commitment fee due on the revolving credit facility was 0.25% in 2015 and 0.5% in 2014. As of December 31, 2015, we had no outstanding borrowings under the SunTrust credit facility. The Company was in compliance with the covenants in its SunTrust credit facility as of December 31, 2015. Future Minimum Payments There were no future minimum principal payments of debt as of December 31, 2015 and 2014.
