Bank Financing Arrangements	NOTE 5 — Bank Financing Arrangements On October 12, 2011, the Company entered into a new credit facility agreement with Silicon Valley Bank (the “Bank”). This credit facility allows the Company to borrow up to $2,500,000 based on the level of qualified domestic and international receivables, up to a maximum of $1,500,000 and $1,000,000, respectively. Advances against the domestic line are calculated at 80% of qualified receivables except for receivables from distributors which are calculated at 60%. Advances against the international line are calculated at 90% against qualified hedged receivables and 70% against qualified non-hedged receivables and receivables from distributors. Borrowings under the lines bear an annual interest rate equal to the greater of (i) the Bank’s prime rate plus 1%, or (ii) 5%. The rate in effect has been 5% to date. There is also a collateral handling fee of 0.25% per month of the financed receivable balance outstanding. The applicable interest and fees are calculated based on the full amount of the accounts receivable provided as collateral for the actual amounts borrowed. The credit facility agreement expires on October 12, 2013 unless renewed. The agreement may be terminated by the Company or by the Bank at any time. Upon such termination, the Bank would no longer make advances under the credit agreement and outstanding advances would be repaid as receivables are collected. All advances are at the Bank’s discretion and the Bank is not obligated to make advances. In addition, the Company must maintain a minimum liquidity ratio at all times calculated based on quick assets (unrestricted cash equivalents at the Bank plus net eligible accounts receivable) to outstanding obligations to the Bank of not less than 2.0 to 1.0. The outstanding amounts borrowed under the domestic and international lines at December 31, 2012 were $479,647 and $331,039, respectively, and the full amounts of accounts receivable provided as collateral were $777,987, and $464,731, respectively. The outstanding amounts borrowed under the domestic and international lines at December 31, 2011 were $921,621 and $187,979, respectively, and the full amounts of accounts receivable provided as collateral were $1,481,039, and $266,006, respectively. Interest expense on the amounts drawn during the years ended December 30, 2012 and 2011 were $98,861 and $24,047, respectively. Accrued interest related to the amounts outstanding at December 31, 2012 and 2011 was $7,237 and $10,477, respectively. In the 2010 year presented up through November 2, 2010, the Company had a credit facility with the Bank which allowed the Company to borrow up to $2,500,000 based on the level of qualified domestic and international receivables, up to a maximum of $1,500,000 and $1,000,000, respectively. Borrowings under the lines bore an annual interest rate equal to the greater of (i) the Lender's prime rate plus 2%, or (ii) 6%. The annual interest rate in effect throughout fiscal 2010 was 6%. The borrowings under the credit facility were secured by a first priority security interest in the assets of the Company. The advance rate for receivables was 50% from distributors and 70% for all other receivables. The agreement also specified a collateral handling fee of 0.62% per month. The applicable interest and fees were calculated based on the full amount of the accounts receivable provided as collateral, rather than on the actual amounts borrowed. On November 2, 2010, in anticipation of issuing a senior convertible note which subsequently closed on November 19, 2010, the Company repaid in full its outstanding indebtedness to the Bank and terminated the lines of credit (see “NOTE 6 — Senior Convertible Note Financing” for more information). All obligations of the Company under the credit facility and any other related loan and collateral security documents, except those which specifically survive the termination of such agreements, were terminated at that time. Subsequent to the full conversion of the Company’s convertible note on September 6, 2011, the Company entered into a new credit facility agreement with the Bank as described previously.
