On July 29, 2015, we amended the terms of our Revolving Credit and Security Agreement with PNC Bank (Amendment No. 9). The terms of Amendment No. 9 principally include a reduction in the minimum availability threshold from $12.5 million to $5.0 million. Amendment No. 9 also includes other changes regarding the inclusion of in-transit inventory and foreign accounts receivable in the calculation of the borrowing base.
