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. Additionally, our Excess Availability must not fall below $5,000. As of December 31, 2013, our Liquidity was in excess of $15,000 and Excess Availability was in excess of $5,000; had we not met these thresholds at December 31, 2013, we would not have met the required 1.0:1.0 fixed charge coverage ratio test.
