Fair Value Measurements
Marketable securities valued utilizing Level 1 inputs include active exchange-traded equity securities and equity index funds, certificates of deposits, and most U.S. government debt securities, as these securities all have quoted prices in active markets. Marketable securities valued utilizing Level 2 inputs include asset-backed securities, most corporate bonds and municipal bonds. These securities are valued using market corroborated pricing, matrix pricing or other models that utilize observable inputs such as yield curves.
The following table presents information about our investments measured at fair value on a recurring basis as of December 31, 2024 and 2023, and indicates the fair value hierarchy of the valuation techniques utilized to determine such fair value (in millions):
