4. Fair Value Measurements

 

There were no available-for-sale securities as of December 31, 2025 and 2024.

 

The Company’s investments, including cash equivalents, are all classified within Levels 1 of the fair value hierarchy and are valued based on quoted prices in active markets. For cash, accounts receivable, 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.

 

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