Note 3. Fair Value Measurements

Assets and liabilities recorded at fair value on a recurring basis in the condensed consolidated balance sheets are categorized based upon the level of judgment associated with the inputs used to measure their fair values. Fair value represents 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. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The authoritative guidance on fair value measurements establishes a three-tier fair value hierarchy for disclosure of fair value measurements as follows:

A financial instrument’s categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires management to make judgments and consider factors specific to the asset or liability.

The Company’s financial assets consist of Level 1 and 2 assets. The Company classifies its cash equivalents and marketable debt securities within Level 1 or Level 2 because they are valued using either quoted market prices or inputs other than quoted prices which are directly or indirectly observable in the market, including readily-available pricing sources for the identical underlying security which may not be actively traded. The Company’s fixed income available-for-sale securities consist of high quality, investment grade securities from diverse issuers. The valuation techniques used to measure the fair value of the Company’s marketable debt securities were derived from non-binding market consensus prices that are corroborated by observable market data and quoted market prices for similar instruments.

The Company’s financial liabilities measured at fair value on a recurring basis consist of Level 2 and Level 3 liabilities. The Company classifies the Private Placement Warrants (as defined in Note 8) within Level 2, because they were valued using inputs other than quoted prices which are directly observable in the market, including readily available pricing for the Company's Public Warrants (as defined in Note 8). The Company classifies the Earnout Shares Liability (as defined in Note 8) within Level 3. The Earnout Shares Liability is measured at fair value on a recurring basis. Changes in fair value of Level 3 liabilities are recorded in other income, net, in the condensed consolidated statements of operations.

The following tables set forth the fair value of the Company’s financial assets and liabilities measured on a recurring basis by level within the fair value hierarchy as of March 31, 2022 and December 31, 2021 (in thousands):

There were no transfers between Level 1, Level 2 or Level 3 financial instruments in the three months ended March 31, 2022 and 2021.

The fair value of the Earnout Shares Liability (see Note 8) are based on significant unobservable inputs, which represent Level 3 measurements within the fair value hierarchy.
