Fair Value Measurement Fair Value Measurement
 
Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. Three levels of inputs, of which the first two are considered observable and the last unobservable, may be used to measure fair value which are the following:
 
•Level 1—Quoted prices in active markets for identical assets or liabilities. The Company considers a market to be active when transactions for the asset occur with sufficient frequency and volume to provide pricing information on an ongoing basis.
•Level 2—Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.
•Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. The valuation of Level 3 investments requires the use of significant management judgments or estimation.

The Company’s fair value hierarchies for its financial assets and liabilities, which require fair value measurement on a recurring basis are as follows:
  Total Level 1 Level 2 Level 3
September 30, 2022        
Liabilities        
Warrant liabilities $ 539  $ —  $ —  $ 539 
December 31, 2021
Liabilities
Warrant liabilities $ 1,550  $ —  $ —  $ 1,550 
 
The following table sets forth a summary of the changes in the fair value of the Company’s Level 3 financial liabilities for the nine months ended September 30, 2022, which were measured at fair value on a recurring basis:
  Warrant Liability
Balance at December 31, 2021 $ 1,550 
Gain on revaluation of warrants issued in connection with the February 2021, June 2020, December 2019 and May 2019 financings (1,011)
