The fair value of the warrant liability was determined based on Level 3 inputs and utilizing the Black-Scholes option pricing model (see Note 10). Significant changes to these assumptions would result in increases or decreases to the fair value of the warrant liability. During the three months ended March 31, 2022 and 2 0 21, there were no transfers into or out of Level 3. The following table set forth a summary of changes in the fair value of the common stock warrants, which represents a recurring fair value measurement that is classified within Level 3 of the fair value hierarchy. Changes in fair value are recognized in other (expense) income as “Change in fair value of warrant liability” in the Company’s unaudited condensed consolidated statements of operations and comprehensive loss (in thousands):
Common Stock (12,686 warrants) |  |  |  |
Fair value at December 31, 2021 |  | $ |  | 83 |
Change in fair value |  |  |  | 44 |
Fair value at March 31, 2022 |  | $ |  | 127 |
