Fair Value Measurements |
Fair Value Measurements | 10. Fair Value Measurements The Company follows accounting guidance that emphasizes that fair value is a market-based measurement, not an entity specific measurement. Fair value is defined as “the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.” Fair value measurements are defined on a three level hierarchy: Level 1 inputs: Unadjusted quoted prices for identical assets or liabilities in active markets; Level 2 inputs: Quoted prices for similar assets and liabilities in active markets, quoted prices in markets that are not active, or inputs which are observable, whether directly or indirectly, for substantially the full term of the asset or liability; Level 3 inputs: Unobservable inputs that reflect the Company’s own assumptions about the assumptions market participants would use in pricing the asset or liability in which there is little, if any, market activity for the asset or liability at the measurement date. There were no financial instruments measured on a recurring basis as of December 31, 2021. The fair value of financial instruments measured on a recurring basis as of December 31, 2022 are as follows: ​

​ The fair value of the 2022 Warrants was determined using a Monte Carlo simulation. This valuation technique involves a significant amount of estimation and judgment. In general, the assumptions used in calculating the fair value of the common stock warrant liability represent management’s best estimate, but the estimate involves inherent uncertainties and the application of significant management judgment. ​ Input assumptions were as follows:
​ | ​ | ​ | ​
​ | As of
​ | December 31,
​ | 2022
Stock Price | $ | 0.72 | ​
Exercise Price | ​ | — | ​
Risk free interest rate | ​ | 3.9-4.6 | %
Volatility | ​ | 94-103 | %
Remaining term (years) | ​ | 1.0-5.0 | ​
​ Due to the cashless exercise provision of the 2022 Warrants rendering the exercise price effectively at zero, the calculated price per share of the 2022 Warrants was equal to that of a share of common stock The following table provides a roll-forward of the warrant liabilities measured at fair value for the year ended December 31, 2022: ​
