The Credit Facility was modified through an amendment in December 2015, which increased the borrowing base to $15 million (from the previous $10 million) with an additional accordion feature that allows the Company to request an additional $5.0 million as needed, extending the total credit facility borrowing capacity to $20 million over its three-year term. The Credit Facility is collateralized by substantially all assets of the Company and its domestic subsidiaries, and is subject to normal financial covenants. The Company was not in compliance with one of its loan covenants as of December 31, 2017.
