Fair Value Measurements Fair Value Measurements
The Company’s debt instruments are recorded at their carrying values in its consolidated balance sheets, which may differ from their respective fair values. The estimated fair value of the Company’s 2027 Notes and 2029 Notes are both based on Level 2 inputs as the fair value is based on quoted prices for the Company’s debt (see Note 9 — Debt for additional information). The fair values of the Company’s short- term loans generally approximated their carrying values.
At December 31, 2024 and 2023, the Company held currency forward contracts with an aggregated notional amount of $28,160 and $12,325, respectively, to sell United States dollars and to buy various foreign currencies such as Canadian dollars and Euro, among others, at a forward rate. Any changes in the fair value of these contracts are recorded in Other income (expense), net in the consolidated statement of operations. During the year ended December 31, 2024 and 2023, the Company recorded a net loss of $1,649 and $848, respectively. For the year ended December 31, 2022 the net loss was de minimus.
The following table presents the Company’s fair value hierarchy for financial assets and liabilities:

Contingent Considerations
Contingent considerations were valued based on the consideration expected to be transferred. The Company estimated the fair value based on a Monte Carlo Simulations analysis to simulate the probability of achievement of various milestones identified within each contingent consideration arrangement, using certain assumptions that require significant judgement and discount rates. The discount rates were based on the estimated cost of debt plus a premium, which included consideration of expected term of the earn-out payment, yield on treasury instruments and an estimated credit rating for the Company.
The following table presents the significant unobservable inputs assumed for each of the fair value measurements:
