Fair value measurements

Note 20. Fair value measurements

Our financial instruments consist of cash, cash equivalents, accounts receivable, accounts payable, and debt obligations, if any. Cash, cash equivalents, accounts receivable and accounts payable are stated at their carrying value, which approximates fair value due to the short time to the expected receipt or payment date. The carrying values of debt obligations bearing variable rates of interest, if any, are also considered to approximate fair value due to applicable interest rates resetting to market rates periodically. The fair value of our fixed-rate debt obligations, if any, will be impacted by changes in market rates for similar debt subsequent to our initial borrowings.

Certain of our cash equivalents include deposits in money market funds that invest primarily in short-term securities issued or guaranteed by the U.S. government or its agencies or instrumentalities and contain no restrictions on immediate redemption. The carrying value for money market fund deposits approximates fair value based on quoted prices in active markets for units held (Level 1 classification) and totaled $13.9 million at December 31, 2023 and $25.4 million at December 31, 2022.

We did not hold any other financial instruments measured at fair value on a recurring basis as categorized within the fair value hierarchy at December 31, 2023 and 2022.
