Revolving line North America. On September 24, 2014, the Company entered into a Credit and Security agreement with a financial institution (as amended, "Credit Agreement"). Under the terms of the Credit Agreement, which matures on September 24, 2018, the Company can borrow up to a combined $15.0 million in the U.S. and Canada, subject to borrowing base availability from secured domestic and certain Canadian assets, such as accounts receivable and inventory, and other requirements, under a revolving line of credit. The Credit Agreement covenants restrict debt, liens, and investments, and require attainment of specific levels of profitability and cash flows. On January 31, 2017, the Company was in compliance with all covenants under the Credit Agreement. The domestic revolving line balances as of January 31, 2017 and 2016 were included as current liabilities in the consolidated balance sheets, because the Credit Agreement has a subjective acceleration clause.

Interest rates vary based on the average availability in the preceding fiscal quarter and are: (a) a margin in effect plus a base rate, if below certain availability limits; or (b) a margin in effect plus the Eurodollar rate for the corresponding interest period. On January 31, 2017, the Company had borrowed $3.8 million at 5%, 3.77% and 3.95% and had $5.8 million available to it under the revolving line of credit.
