The Company classifies money market funds, commercial paper, U.S. government securities, U.S. agency securities, asset-backed securities, corporate debt securities, and certificate of deposits within Level 1 or Level 2 of the fair value hierarchy because the Company values these investments using quoted market prices or alternative pricing sources and models utilizing market observable inputs.

The Company determines the fair value of contingent consideration based on a probability-weighted discounted cash flow analysis. The fair value remeasurement is based on significant inputs not observable in the market and thus represents a Level 3 measurement as defined in the fair value hierarchy. In each period, the Company reassesses its current estimates of performance relative to the stated targets and adjusts the liability to fair value. Any such adjustments are included in Other income (expense), net in the Condensed Consolidated Statements of Operations and Comprehensive Loss.

There were no transfers of financial instruments between the fair value hierarchy levels during the three and six months ended June 30, 2023 and the year ended December 31, 2022.
