Line of Credit	Line of Credit On October 2, 2012, we entered into an Amended and Restated Credit Agreement ("Amended Credit Agreement") with U.S. Bank National Association ("U.S. Bank") which provides for a $55.0 million line of credit ("Credit Line") that may be used for working capital and other general corporate purposes including acquisitions, share repurchases and capital expenditures. The Amended Credit Agreement expires on November 1, 2014. Amounts available for borrowing under the Credit Line are reduced by the balance of any outstanding letters of credit, of which there were $13 thousand at June 30, 2013. All obligations under the Credit Line are secured by substantially all of our U.S. personal property and tangible and intangible assets as well as 65% of our ownership interest in Enson Assets Limited, our wholly-owned subsidiary which controls our manufacturing factories in the People's Republic of China ("PRC"). Under the Amended Credit Agreement, we may elect to pay interest on the Credit Line based on LIBOR plus an applicable margin (varying from 1.25% to 1.75%) or base rate (based on the prime rate of U.S. Bank or as otherwise specified in the Amended Credit Agreement) plus an applicable margin (varying from -0.25% to +0.25%). The applicable margins are calculated quarterly and vary based on our leverage ratio as set forth in the Amended Credit Agreement. There are no commitment fees or unused line fees under the Amended Credit Agreement. The Amended Credit Agreement includes financial covenants requiring a minimum fixed charge coverage ratio, a maximum leverage ratio and minimum liquidity levels. In addition, the Amended Credit Agreement also contains other customary affirmative and negative covenants and events of default. As of June 30, 2013, we were in compliance with the covenants and conditions of the Amended Credit Agreement. Our total interest expense on borrowings was $16 thousand and $0.1 million during the three months ended June 30, 2013 and 2012, respectively. Our total interest expense on borrowings was $49 thousand and $0.2 million during the six months ended June 30, 2013 and 2012, respectively.
