Debt Disclosure [Abstract] |
Line of Credit | Line of Credit On October 27, 2017, we entered into a Second Amended and Restated Credit Agreement ("Second Amended Credit Agreement") with U.S. Bank National Association ("U.S. Bank") and Wells Fargo Bank, National Association. Under the Second Amended Credit Agreement, the existing revolving line of credit ("Credit Line") was increased from $125.0 million to $170.0 million and the expiration date remained November 1, 2019. The Credit Line may be used for working capital and other general corporate purposes including acquisitions, share repurchases and capital expenditures. Amounts available for borrowing under the Credit Line are reduced by the balance of any outstanding letters of credit. There were no outstanding letters of credit at December 31, 2017. 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 PRC. Under the Second 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 Second Amended Credit Agreement) plus an applicable margin (varying from 0.00% to 0.50% ). The applicable margins are calculated quarterly and vary based on our cash flow leverage ratio as set forth in the Second Amended Credit Agreement. The interest rate in effect at December 31, 2017 was 3.04%. There are no commitment fees or unused line fees under the Second Amended Credit Agreement. The Second Amended Credit Agreement includes financial covenants requiring a minimum fixed charge coverage ratio and a maximum cash flow leverage ratio. In addition, the Second Amended Credit Agreement contains other customary affirmative and negative covenants and events of default. As of December 31, 2017, we were in compliance with the covenants and conditions of the Second Amended Credit Agreement. At December 31, 2017, we had $138.0 million outstanding under the Credit Line. Our total interest expense on borrowings was $2.7 million, $1.3 million and $0.3 million during the years ended December 31, 2017, 2016 and 2015, respectively.
