Credit Facility	11. CREDIT FACILITY On January 2, 2013, the Company entered into a three-year term agreement with a bank to provide the Company with a senior secured credit facility of up to $25.0 million. The agreement provided for the Company to borrow up to 80% of eligible accounts receivable and up to 35% of domestically held raw material and finished goods inventory. Advances against inventory were limited to 40% of the aggregate outstanding on the revolving line of credit and $10.0 million in aggregate. The Company had the option to borrow at an interest rate of LIBOR plus 2.75% or the Wall Street Journal prime rate plus 0.50%. If the Company maintained liquidity of $20.0 million or greater with the lending institution, then the borrowing interest rate options were LIBOR plus 2.25% or the Wall Street Journal prime rate. There was an unused revolving line facility fee of 0.375% per annum. The facility was secured by a first priority interest in substantially all of the Company’s personal property, excluding intellectual property. The Company was required to maintain an adjusted quick ratio of 1.40 to 1.00, maintain operating and other deposit accounts with the bank or bank’s affiliates of 25% of the Company’s total worldwide cash, securities and investments, and the Company could pay dividends or repurchase capital stock only with the bank’s consent during the three-year term. In August 2015, the Company entered into an amended agreement with the bank to extend the senior secured facility through January 2, 2018. Under the amended agreement, advances against inventory were limited to the lesser of 45% of the aggregate outstanding principal on the revolving line of credit and $10.0 million and the rate on the facility fee on the unused portion of the revolving line was adjusted to 0.50% per annum. All other terms and conditions remained the same. The agreement contained a subjective acceleration clause and required the Company to maintain a lockbox. As a result, the Company classified the debt as a current liability on its balance sheet. On September 9, 2016, the Company voluntarily terminated the loan agreement. Pursuant to the pay-off letter for termination of the loan agreement, upon payment of the pay-off amount, all obligations under the loan agreement were paid and discharged in full, all unfunded commitments by the bank to make credit extensions to the Company under the loan agreement were terminated, all security interests granted to or held by the bank under the loan agreement were released, and all guaranties supporting the loan agreement were released. The Company did not incur any early termination penalties in connection with the termination. For the three and nine months ended September 30, 2016, the Company recorded interest expense of $27,500 and $98,200, respectively, related to the credit facility which includes $24,200 and $87,000, respectively, of interest expense charged on the unused portion of the facility. For the nine months ended September 30, 2015, the Company did not draw on this facility. For the three and nine months ended September 30, 2015, the Company recorded $29,000 and $76,000, respectively, of interest expense charged on the unused portion of the facility.
