Fair Value Measurements

Note 4. Fair Value Measurements

Financial assets and liabilities are recorded at fair value.

The Company classifies fair value measurements using a three-level hierarchy that prioritizes the inputs used to measure fair value. This hierarchy requires entities to maximize the use of observable inputs and minimize the use of unobservable inputs. The three levels of inputs used to measure fair value are as follows:

•
Level 1—Quoted market prices (unadjusted) in active markets for identical assets and liabilities.
•
Level 2—Observable inputs other than quoted market prices included in Level 1, such as quoted market prices for markets that are not active or other inputs that are observable or can be corroborated by observable market data.
•
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, including certain pricing models, discounted cash flow methodologies and similar techniques that use significant unobservable inputs. These fair values are obtained from independent pricing services which utilize Level 1 and Level 2 inputs.

Financial Assets

The following table summarizes the Company's financial asset instruments measured at fair value on a recurring basis as of December 31, 2024 and 2023 (in thousands). Included within cash and cash equivalents on the consolidated balance sheets, but excluded from the fair value hierarchy table, are cash deposits held at financial institutions.

The following table summarizes the Company's warrant liabilities (see Note 8. Stockholders' Equity) measured at fair value on a recurring basis as of December 31, 2024 and 2023 (in thousands) and was based on significant inputs not observable in the market, which represents a Level 3 measurement within the fair value hierarchy.
