(7) | Long-term Notes Payable (including current portion) and Line of Credit
In June 2012, the Company amended its line of credit with Silicon Valley Bank. The amended revolving line of credit facility allows for an advance up to $3.0 million. The facility bears an interest rate of prime (4.50% as of December 31, 2017) plus 1.25%. The revolving credit facility is available as long as the Company maintains a liquidity ratio of cash and cash equivalents plus accounts receivable to outstanding debt under the facility of 1.25 to 1.00; otherwise, the facility reverts to its previous eligible receivables financing arrangement. The amended facility matures in April 2018. In January 2018, the Company amended and restated the revolving line of credit to increase the amount from $3.0 million to $10.0 million and extend the maturity date to January 31, 2020. See Note 17 for additional details. The bank has a first security interest in all the Company’s assets excluding intellectual property, for which the bank has received a negative pledge. There was no balance owed on the line of credit as of December 31, 2017 and 2016. In December 2013, the Company further amended its revolving line of credit under the amended and restated loan and security with Silicon Valley Bank to include a growth capital term loan of up to $750,000. The growth capital term loan required interest only payments through June 30, 2014 at which point it was to be repaid in 32 equal monthly installments of interest and principal. The growth capital term loan matured on February 1, 2017, at which time $55,230 in principal and accrued interest was paid. The growth capital term loan interest rate was 6.5%. As of December 31, 2017 there was no balance owed under this loan. In December 2015, the Company further amended its amended and restated loan and security agreement with Silicon Valley Bank to include a term loan in the amount of $4.0 million. The loan requires 36 monthly installments of interest and principal. The loan matures on December 1, 2018. Effective September 2017, the Company further amended its amended and restated loan and security agreement with Silicon Valley Bank to update the financial covenants. The amended and restated loan and security agreement requires the Company to maintain, at all times, measured as of the last day of each month (unless otherwise specified) either (i) a minimum cash balance of unrestricted cash at Silicon Valley Bank or its affiliate of not less than $25.0 million or (ii) a liquidity ratio of 1.25 to 1.00 and a minimum EBITDA, measured as of the last day of each fiscal quarter for the previous six month period (for December 31, 2017 the minimum EBITDA is 750,000). The interest rate is fixed at 5%. As of December 31, 2017 and 2016, $1,333,333 and $2,666,666 was outstanding under this loan, respectively. The remaining principal payments on the $4.0 million term loan subsequent to December 31, 2017 are as follows:
