Debt Disclosure [Abstract] |
Debt and Related Warrants | Debt and Related Warrants In July 2015, the Company entered into a revolving debt facility (“Loan and Security Agreement”). The Loan and Security Agreement was subsequently amended and restated, the First Amended and Restated Loan and Security Agreement, in November 2018 to increase the available borrowings to $18.0 million and extend the maturity date to April 2021. In December 2020, the Company entered into the Second Amended and Restated Loan and Security Agreement, which provided a $40.0 million revolving credit facility with a maturity date of November 30, 2023. The Company’s obligations under the agreement contain certain customary covenants, including, but not limited to, those relating to additional indebtedness, liens, asset divestitures, and affiliate transactions. The agreement also contains a liquidity covenant equal to the greater of (i) $5.0 million or (ii) total 6-month adjusted EBITDA burn when the sum of the outstanding principal amounts are equal or in excess of $18.0 million. The revolving credit facility bears interest on outstanding borrowings as the sum of the Daily Adjusting LIBOR Rate for such day plus 2.50% plus an applicable margin of 0.25% per annum. The Company did not have an outstanding balance under the Loan and Security Agreement as of September 30, 2021. Additionally, the revolving debt facility includes an unused facility fee equal to 0.25% per annum of the difference between the total revolving credit facility and the average outstanding principal balance of the obligations under the revolving credit facility during each quarter. In connection with its amended and restated loan and security agreements, at various times, the Company granted warrants to purchase 49,869 shares of the Company’s common stock at exercise prices ranging from $0.525 per share to $10.80 per share. The warrants are exercisable for 10 years. At the time of issuance, the Company determined the estimated fair value of the warrants. As the warrants represent a freestanding equity instrument, the Company recorded the fair value of the warrants in additional paid in capital. All warrants remain outstanding at September 30, 2021. Substantially all the Company’s assets are pledged as collateral for these loans. The Company is required to meet certain nonfinancial covenants. In March 2020, the Company borrowed $17.0 million on its revolving debt facility. The Company repaid the $17.0 million outstanding balance on the revolving debt facility in October 2020. Additionally, the Company applied for and received a loan under the Paycheck Protection Program in April 2020 totaling $6.3 million. The Company subsequently repaid the outstanding balance of $6.3 million in April 2020. The Company incurred nominal aggregate debt issuance costs in connection with its loan and security agreements. These costs are being amortized to non-cash interest expense over the terms of the related indebtedness using the straight-line method which approximates the effective interest method.
