Term Loan

In December 2015, the Company entered into a loan and security agreement (“Term Loan”) with Silicon Valley Bank (the “Bank”) providing for a senior secured term loan facility in the amount of $25.0 million, which proceeds were used to repay all existing debt. In July 2017, the Company repaid the $25.0 million term loan with Silicon Valley Bank, along with the $625,000 end-of-term fee and $500,000 prepayment fee.

The Term Loan accrued interest at a floating annual rate equal to nine tenths of one percentage point (0.90%) above the prime rate published from time to time in The Wall Street Journal. The agreement required the Company to make monthly interest-only payments through December 2017. After this date, the Company was required to make thirty-six (36) equal monthly installments of principal, plus accrued interest. The Company’s final payment, due on the maturity date of December 1, 2020, was to include all outstanding principal and accrued and unpaid interest plus a final payment equal to $625,000. In the event the loan was repaid prior to its maturity, the Company was responsible for (i) all outstanding principal plus accrued and unpaid interest, (ii) a prepayment fee equal to 2% of the outstanding principal balance if prepayment occurs after December 29, 2016, but on or prior to December 29, 2017, and 1% of the outstanding principal amount if the prepayment occurs after December 29, 2017, (iii) the final payment of $625,000, and (iv) other bank expenses. The loan was recorded on the Consolidated Balance Sheet, net of issuance fees.

The loan and security agreement contained customary events of default and covenants, including a financial covenant that required the Company to maintain either a liquidity ratio (defined as the ratio of the Company’s cash, cash equivalents and net accounts receivable to the Company’s obligation owed to the Bank) of at least 1.4:1.0, or to cash collateralize 100% of the Company’s obligations to the Bank. The Company’s obligations to the Bank were secured by substantially all of the Company’s assets, excluding intellectual property. The Term Loans’ prepayment and end of term fees of $1.1 million were recorded as a loss on extinguishment of debt, along with $41,000 of deferred loan issuance fees, partially offset by $267,000 of end of term fees previously amortized, netting to a loss of $900,000. As of the payoff date, the Company was in compliance with all covenants.

The Company recognized interest expense of $43,000, $747,000, $331,000 and $985,000 for the three and nine months ended September 30, 2017 and 2016, respectively. Of the total interest expense recognized, $0, $98,000, $50,000 and $148,000 were related to the amortization of the debt discount and end of term payment for both the three and nine months ended September 30, 2017 and 2016, respectively.
