Fair Value Measurements

9 Months Ended

Sep. 30, 2022

4.	Fair value measurements

Fair value is defined as the price that would be received upon the sale of an asset or paid to transfer a liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value maximize the use of observable inputs and minimize the use of unobservable inputs. The fair value hierarchy defines a three-level valuation hierarchy for disclosure of fair value measurements as follows:

●	Level 1 — Inputs are quoted prices in active markets for identical assets or liabilities.

●

Level 2 — Inputs include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, and inputs (other than quoted prices) that are observable for the asset or liability, either directly or indirectly.

●	Level 3 — Inputs are unobservable for the asset or liability.

There was no convertible preferred stock warranty liability as of the periods ended September 30, 2022 and December 31, 2021.

The Company’s recurring fair value measurements using significant unobservable inputs (Level 3) related solely to the Company’s convertible preferred stock warrant liability. The convertible preferred stock warrant liability was remeasured at each financial reporting period with any changes in fair value being recognized as a component of other income (expense), net in the condensed consolidated statements of operations and comprehensive loss. In connection with the closing of the initial public offering (“IPO”), all of the outstanding convertible preferred stock warrants were converted to common stock warrants. The related liability was remeasured at the time of the IPO and reclassed to additional paid-in capital.

The following table sets forth a summary of changes in the estimated fair value of the Company’s convertible preferred stock warrants during the nine months ended:
