10. Fair Value Measurements

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market in an orderly transaction between market participants at the measurement date. The fair value hierarchy prioritizes the inputs to valuation techniques used in measuring fair value. There are three levels to the fair value hierarchy based on the reliability of inputs, as follows:Level 1 – Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets.Level 2 – Inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly.Level 3 – Unobservable inputs in which little or no market data exists, therefore requiring us to develop our own assumptions.Financial instruments measured at fair value are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. Our 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 use of different assumptions and/or estimation methodologies may have a material effect on estimated fair values. Accordingly, the fair value estimates disclosed, or amounts recorded, may not be indicative of the amount that we or holders of the instruments could realize in a current market exchange.The tables below provide information, by level within the fair value hierarchy, of our financial assets and liabilities that are accounted for at fair value on a recurring basis as of March 31, 2025 and December 31, 2024 (in thousands):As of March 31, 2025 Quoted Prices in Active Markets for Identical Items (Level 1)Significant Other Observable Inputs(Level 2)Significant Unobservable Inputs(Level 3)TotalAssetsMoney market funds(1)$83,858 $— $— $83,858 U.S. government securities - AFS(2)$183,332 $— $— $183,332 Trading securities(2)$2,130 $— $— $2,130 LiabilitiesTerm Debt (3)(4)$— $10,032 $— $10,032
