Line of Credit Facility, Description								The 2012 Credit Facility contains customary affirmative, negative and financial covenants. The 2012 Credit Facility requires that we maintain a fixed charge coverage ratio of not less than 1.0:1.0 at any time that our Liquidity (defined as the aggregate amount of unrestricted cash and cash equivalents on hand plus Excess Availability (as defined in the Credit Facility)) or Excess Availability fall below stipulated levels. The Second Amendment provided for tiered thresholds. Through December 31, 2013, our Liquidity must not fall below $15,000. Thereafter, our Liquidity must not fall below $20,000. Our Excess Availability must not fall below $4,000 through September 30, 2013. This minimum threshold increases by $250 monthly through December 31, 2013, at which time and thereafter, our Excess Availability must not fall below $5,000. As of September 30, 2013, our Liquidity was in excess of $15,000 and Excess Availability was in excess of $4,000; had we not met these thresholds at September 30, 2013, we would not have met the required 1.0:1.0 fixed charge coverage ratio test.			The $5,000 Wells Fargo Term Loan was provided for within the First Amendment to the 2012 Credit Facility. We were scheduled to pay monthly installments of $208 through February 2015 at an annual interest rate of 6% plus 3 Month LIBOR. The Second Amendment to the 2012 Credit Facility increased our total Term Loan by $10,147 to $13,708 at September 30, 2013. The Wells Fargo Term Loan is payable in equal monthly installments of $292 through August 9, 2016, with the residual unpaid principal balance due on that date. The Second Amendment also extended the term and reduced the annual interest rate to 5% plus 3 Month LIBOR, through September 13, 2014. Following that time, the Wells Fargo Term Loan amounts outstanding bear interest at a per annum rate equal to a Daily Three Month LIBOR plus an interest rate margin, which is determined quarterly, based on the following thresholds:
