Fair Value Measurements |
6.Fair Value Measurements The Company measures the fair value of financial instruments using a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three broad levels. Each level of input has different levels of subjectivity and difficulty involved in determining fair value.
The Company’s financial assets and liabilities that are measured at fair value on a recurring basis as of December 31, 2019 and 2018 by level within the fair value hierarchy, are as follows:
There were no transfers between Level 1, 2 or 3 during the years ended December 31, 2019 or 2018. Warrant Liability The following table includes a summary of changes in fair value of the Company’s warrant liability measured at fair value using significant unobservable inputs (Level 3) for the years ended December 31, 2019 and 2018:
The changes in fair value of the warrant liability are recorded in change in fair value of warrant liability in the consolidated statements of operations. A summary of the weighted average significant unobservable inputs (Level 3 inputs) used in measuring the Company’s warrant liability that is categorized within Level 3 of the fair value hierarchy as of December 31, 2019 and 2018 is as follows:
Derivative Liability The following table includes a summary of changes in fair value of the Company’s derivative liability measured at fair value using significant unobservable inputs (Level 3) for the years ended December 31, 2019 and 2018:
As of December 31, 2017, the Company measured the fair value of the derivative by estimating the fair value of the convertible notes payable at certain conversion points. To calculate the fair value of the convertible notes payable with the conversion feature, the Company calculated the present value of the convertible notes payable upon conversion at a qualifying IPO in the second quarter of 2018, and the present value of the convertible notes payable at non-qualifying IPO in the fourth quarter of 2018. The Company estimated a probability of 50% for the occurrence of a qualifying IPO in the second quarter of 2018 and a probability of 50% in the fourth quarter of 2018. The Company’s derivative liability during the period ended July 25, 2018 was measured at fair value using the Probability Weighted Expected Return valuation methodology. The weighted average significant unobservable inputs (Level 3 inputs) used in measuring the Company’s embedded conversion options during that period are as follows:
As of July 25, 2018, the date of the Company’s successful initial public offering, the Company measured the fair value of the derivative related to the convertible notes payable by estimating the fair value of the underlying shares using the offering price of $5.00. On July 25, 2018, the derivative liability was reclassified to equity upon the Company’s initial public offering. As of December 31, 2019, the Company measured the fair value of the derivative related to the convertible preferred stock by estimating the fair value of the Series A Preferred Stock as if conversion occurred on December 31, 2019. The Company calculated value of the conversion feature using the Fixed Conversion Price of the Series A Preferred Stock, as adjusted to 95% of the volume weighted average price of the common stock for the previous ten trading days and the specified floor price of $1.50. There was no change in the fair value of the derivative liability because the volume weighted average price of the common stock was below the specified floor price. |
