Loan Agreement | In 2012, the Company entered into a Loan and Security Agreement (“Loan Agreement”). The Loan Agreement consists of a $40.0 million revolving line of credit facility, which includes a $10.0 million sub-facility for letters of credit. Certain terms of the original Loan Agreement were revised in December 2013, by a Second Amendment to Loan and Security Agreement ("Second Amendment") and in September 2016, by a Sixth Amendment to Loan and Security Agreement ("Sixth Amendment"). The Loan Agreement, as amended, expires in August 2020. Due to the lock box arrangement and a subjective acceleration clause contained in the Loan Agreement, any outstanding borrowings under the revolving line of credit are classified as a current liability. Currently, credit available under the Loan Agreement, as amended, is based upon: a) 85% of the face amount of the Company’s eligible accounts receivable, generally less than 60 days past due, and b) the lesser of 60% of the lower of cost or market value of the Company’s eligible inventory, generally inventory expected to be sold within 18 months , or $20.0 million . The applicable interest rates for borrowings are at the Prime rate or, if the Company elects, the LIBOR rate plus 1.50% to 1.85% based on the Company’s debt to EBITDA ratio. The Loan Agreement is secured by a first priority perfected security interest in substantially all existing assets of the Company. Dividends are restricted to amounts not to exceed $7.0 million annually. At September 30, 2016 , the Company had no borrowings under its revolving line of credit facility and additional borrowing availability of $34.8 million . The Company paid interest of $0.5 million and $0.4 million for the nine months ended September 30, 2016 and 2015 , respectively.
