Fair Value of Financial Instruments

12 Months Ended

Dec. 31, 2023

The fair value of an asset or liability represents the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between unrelated market participants.

The Company reports the fair value of assets and liabilities using a three level measurement hierarchy that prioritizes the inputs used to measure fair value. The fair value hierarchy consists of the following three levels:

•Level 1—Valuations based on unadjusted quoted prices in active markets that are accessible at measurement date for identical assets.

•Level 2—Valuations based on quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active and model-based valuations in which all significant inputs are observable in the market, either directly or indirectly (e.g., interest rates; yield curves).

•Level 3—Valuations using significant inputs that are unobservable in the market and inputs that reflect the Company’s own assumptions. These are based on the best information available, including the Company’s own data.

The fair value of the restricted marketable securities which are classified as Level 2 financial assets are recorded in Other assets on the consolidated balance sheets. There have been no transfers of assets or liabilities into or out of Level 3 of the fair value hierarchy.
