FAIR VALUE [Abstract] |
FAIR VALUE | 8. FAIR VALUE FASB guidance on fair value measurements, which defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements for our financial assets and liabilities, as well as for other assets and liabilities that are carried at fair value on a recurring basis in our condensed consolidated financial statements. FASB guidance establishes a three-level fair value hierarchy based upon the assumptions (inputs) used to price assets or liabilities. The three levels of inputs used to measure fair value are as follows: Level 1—Unadjusted quoted prices in active markets for identical assets or liabilities; Level 2—Observable inputs other than those included in Level 1, such as quoted prices for similar assets and liabilities in active markets or quoted prices for identical assets or liabilities in inactive markets; and Level 3—Unobservable inputs reflecting our own assumptions and best estimate of what inputs market participants would use in pricing the asset or liability. Common Stock Warrant Liabilities. Certain of our issued and outstanding warrants to purchase shares of common stock do not qualify to be treated as equity and, accordingly, are recorded as a liability. We are required to record these instruments at fair value at each reporting date and changes are recorded as a non-cash adjustment to earnings. The gains or losses included in earnings are reported in other income (expense) in our condensed consolidated statements of operations. Bridge Note Warrant Liabilities During 2018 and 2019, the Company issued warrants in connection with the issuance of convertible notes. All of these warrants issuances were classified as warrant liabilities (the “Bridge Note Warrant Liabilities”). The Bridge Note Warrant Liabilities are considered Level 3 financial instruments and were valued using the Black Scholes model. As of June 30, 2023, Bridge Note Warrant Liabilities outstanding were the result of convertible note issuances on various dates in 2018 and 2019. The assumptions used in the valuation of the Bridge Note Warrant Liabilities include the following ranges: remaining life to maturity of 0.03 to 0.9 years; volatility rate of 80% to 121%; and risk-free rate of 5.24% to 5.47%. As of December 31, 2022, assumptions used in the valuation of the Bridge Note Warrant Liabilities include: remaining life to maturity of 0.3 to 1.4 years; volatility rate of 69% to 77%; and risk free rate of 4.42 to 4.76%. During the three and six months ended June 30, 2023, the changes in the fair value of the warrant liabilities measured using significant unobservable inputs (Level 3) were less than $1 thousand, respectively. The changes during the three and six months ended June 30, 2022 were comprised of the following: ​
