7.           PLEDGED ASSETS, NOTES PAYABLE AND LONG-TERM DEBT

As of January 31, 2014, the Company had two credit agreements including an operating line of credit and Industrial Revenue Bonds that are secured by its production and headquarters facility in Olathe, Kansas.

The Company’s $6,000,000 operating line of credit provides the Company and its wholly-owned subsidiary with short-term financing for their working capital requirements. The line of credit’s borrowing capacity is calculated as a specified percentage of accounts receivable and inventory on a monthly basis and was amended on October 16, 2013 to extend the expiration date of the line of credit to October 30, 2015.  The total amount of borrowing base for the line of credit as of January 31, 2014 was approximately $4,726,000, all of which was available.  It is secured by accounts receivable and inventory and accrues interest at a performance-based rate that is based on the prime rate (3.25% at January 31, 2014) plus/minus 0.5%.  The interest rate actually assessed is determined by the Company’s debt-to-tangible net worth ratio and was 2.75% on January 31, 2014.  The loan agreement has various covenants, including a financial covenant pertaining to the maintenance of total tangible net worth and a required debt service coverage ratio.  When an amount is outstanding, the borrowings on the line of credit are presented on the balance sheet as long-term in accordance with the terms of the line of credit.
