NOTE 5 — LINES OF CREDIT AND OTHER BORROWINGS

Lines of Credit

The Company entered into two revolving credit facility agreements with Comerica Bank (the “Credit Agreements”) on May 24, 2012. The revolving lines of credit provided for borrowings against certain domestic accounts receivable and inventory (the “Domestic Revolver”) and certain export related accounts receivable and inventory (the “Ex-Im Revolver”).

On July 28, 2014, the Company repaid all amounts outstanding under the Credit Agreements, including principal, accrued interest, and fees which totaled, in the aggregate, approximately $2.9 million, and the Credit Agreements were terminated.

The outstanding principal balances of the Credit Agreements, as amended June 3, 2014, bore interest at annual percentage rates equal to the daily prime rate, plus 2.50% for the Domestic Revolver and 2.00% for the Ex-Im Revolver. The daily prime rate was subject to a floor of the daily adjusting LIBOR rate plus 2.50% per annum, or if LIBOR was undeterminable, 2.50% per annum. The Company was also required to pay an unused commitment fee of 0.25% based on a portion of the undrawn lines of credit, payable quarterly in arrears. During the years ended December 31, 2014 and 2013, the Company incurred $457,000 and $599,000, respectively, of interest expense associated with the credit facilities, including $128,000 and $197,000, respectively, of amortization of deferred debt issuance costs and $200,000 and $179,000, respectively, of amortization of the discount on lines of credit.

Lockbox arrangements under the revolving bank facilities provided that substantially all of the income generated was deposited directly into lockbox accounts and then swept into cash management accounts for the benefit of Comerica Bank. Cash was disbursed from Comerica Bank to the Company only after payment of the applicable debt service and principal. At December 31, 2014 there were no restricted cash amounts. The Company’s obligations were generally secured by substantially all of the Company’s assets now owned or thereinafter acquired.
