The unamortized debt discount as of June 30, 2021 and December 31, 2020 was $1,957 and $2,102, respectively, and is presented in the condensed consolidated balance sheet as a direct deduction from the carrying value of the debt. During the three and six months ended June 30, 2020, a loss of $438 and $1,584 was recorded in other expense in the condensed consolidated statements of operations due to the change in the fair value of the warrant liability. In connection with the IPO, the financial instrument underlying the warrants was converted from the Company’s Series C Preferred Stock to the Company’s Common Stock. As a result of this conversion the Warrants were re-evaluated under ASC 480 Distinguishing Liabilities from Equity and ASC 815 Derivatives and Hedging and reclassified to equity.
