Line of credit description	The revolving credit line is collateralized by the Company's accounts receivable and inventory. The revolving credit line is payable on demand and must be retired for a 30-day period, once annually. If the Company fails to perform the 30-day annual pay down or if the bank elects to terminate the credit line, the bank may, at its option, convert the outstanding balance to a 36-month term note with payments including interest in 36 equal installments.

[1] The letters of credit expire at various times in the fiscal years ending February 28, 2021 and 2022.
