Fair Value Measurements

 

The Company has certain cash equivalents in money market funds that are classified within Level 1 of the fair value hierarchy and are valued based on quoted prices in active markets. For cash, accounts receivables, accounts payable, and accrued interest, the carrying amounts approximate fair value, because of the short maturity of these instruments, and therefore fair value information is not included in the table below. There were no transfers between fair value levels during the nine-month periods ended September 30, 2023 or 2022.

 

The classification of the Company’s cash equivalents within the fair value hierarchy was as follows:
