| Loan and Security Agreement |
6. Loan and Security Agreement The Company entered into a Loan and Security Agreement with Oxford Finance LLC (“Oxford”) and Silicon Valley Bank (“SVB”) in February 2020 (the “LSA”). See “Note 7. Loan and Security Agreement” to the Company’s Financial Statements included in the Annual Report on Form 10-K for the year ended December 31, 2022, or as further described below, for additional information. In June 2022, the Company entered into an amendment to the LSA with Oxford and SVB (the “LSA Amendment”). The LSA Amendment added a financial covenant that requires the Company to maintain a minimum unrestricted cash balance of $10.0 million. The Company was in compliance with the financial covenant under the LSA Amendment as of March 31, 2023. The Loan and Security Agreement previously included a covenant requiring the Company to keep substantially all of its cash and investments with SVB, the substantial majority of which was held in a custodial account with another institution, for which SVB Asset Management was the advisor. In March and April 2023, the Loan and Security Agreement was amended to allow the Company to hold cash and investments at multiple financial institutions. As of March 31, 2023 and December 31, 2022, the Company has classified $13.2 million and $12.5 million, respectively, of the outstanding debt balance as current, and zero and $3.8 million, respectively, as non-current, which reflects the scheduled repayment terms under the February 2020 LSA. As of both March 31, 2023 and December 31, 2022, accrued interest expense was $0.1 million. During the three months ended March 31, 2023 and 2022, the Company recorded interest expense related to loans outstanding of $0.5 million and $0.7 million, respectively, with average interest rates of 10.95% and 8.07%, respectively, which includes interest related to the accretion of debt discount of $0.1 million and $0.1 million, respectively. |
