In September 2016, the Company entered into a Second Amended and Restated Loan and Security Agreement with Silicon Valley Bank (as amended and restated in February 2018 and as further amended, restated or supplemented from time to time, the “Loan and Security Agreement”), which included a term loan and revolving line of credit. On February 20, 2020, the Company prepaid the remaining balance of the term loan and all associated costs. The final payment of $30.5 million included $28.3 million for the outstanding principal balance of the term loan, $1.8 million for an end of term payment, $0.3 million for early termination fees and $0.1 million for interest. The prepayment resulted in a loss on extinguishment of debt of $1.5 million. The non-accreted portion of the end of term payment, unamortized discounts and early termination fees were included in the calculation of the loss on extinguishment of debt.

The revolving line of credit continued to be in effect until its termination at the election of the Company on June 18, 2020. Prior to its termination, the revolving line of credit provided the Company with credit of up to $25.0 million through December 2022. The amount available on the revolving line of credit was based on 80% of eligible receivables and was subject to a borrowing base calculation. Principal amounts outstanding under the revolving line of credit accrued interest at a floating per annum rate equal to the greater of The Wall Street Journal prime rate plus 0.25% or 4.5% and were repayable monthly. Upon termination of the revolving line of credit and the Loan and Security Agreement on June 18, 2020, the Company incurred termination fees of $0.3 million. As of December 31, 2020 and December 31, 2019, there were no balances outstanding under the revolving line of credit.
