The Amended Credit Agreement provides for an $85.0 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. 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 September 30, 2016.

The Amended Credit Agreement includes financial covenants requiring a minimum fixed charge coverage ratio and a maximum cash flow leverage ratio.
