Line of Credit	Line of Credit On October 9, 2014, we extended the term of our Amended and Restated Credit Agreement ("Amended Credit Agreement") with U.S. Bank National Association ("U.S. Bank") to November 1, 2017. The Amended Credit Agreement 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 applicable margins are calculated quarterly and vary based on our cash flow leverage ratio as set forth in the Amended Credit Agreement.

The Amended Credit Agreement includes financial covenants requiring a minimum fixed charge coverage ratio and a maximum cash flow leverage ratio. In addition, the Amended Credit Agreement also contains other customary affirmative and negative covenants and events of default.
