Our current revolving line of credit agreement ("Credit Agreement") with Associated Bank, National Association provides up to $5.0 million. The Credit Agreement expires in May 2013. Any advances are secured by inventories, accounts receivable and equipment. We are subject to certain financial covenants under the Credit Agreement, including minimum debt service coverage ratios, minimum cash flow coverage ratios and financial measures. At March 31, 2012, we had no borrowings under the Credit Agreement, and we were in compliance with all financial covenants.
