Fair Value Measurement
The carrying amount of certain financial instruments, including deposits, accounts payable and accrued expenses, approximates fair value due to their short maturities. Our cash equivalents consist of money market funds denominated in U.S. dollars and certificates of deposit (“CDs”), while our Short-term investments consist of CDs, with the CDs maturing within one year. Our investments include United States Government Mortgage-backed Securities (“U.S. Government Securities”) and Corporate Bonds issued by major United States banks (“Corporate Bonds”), with maturity dates greater than one year but less than five years. The U.S. Government Securities and Corporate Bonds are all rated A1 or above and are classified as held-to-maturity and carried at amortized cost, as the Company has the intent and the ability to hold them until they mature. The carrying values of the U.S. Government Securities and Corporate Bonds are adjusted for accretion of discounts over the remaining life of the investment, while interest or investment income are recognized in investment income in the Company’s consolidated statement of operations. All of the Company’s CDs, U.S. Government Securities and Corporate Bonds were valued using quoted prices for identical instruments in other markets.

In determining the allowance for expected credit losses under ASC 326, Credit Losses, the credit quality and collectability of each class of financial assets are evaluated. For our U.S. Government Securities, CDs and Corporate Bonds, based on the maturity of the instruments and the strong credit ratings and historical performance of the counterparty, analysis indicates a minimal probability of default, and therefore, the expected credit loss is considered to be negligible.

The following table represents the Company’s financial assets measured at fair value on a recurring basis at December 31, 2025, while no such financial instruments were held at December 31, 2024:

About Fair Value Disclosures

Fair value disclosures classify all assets and liabilities measured at fair value into a three-level hierarchy: Level 1 (quoted market prices), Level 2 (observable inputs like yield curves), and Level 3 (unobservable inputs requiring management estimates). The proportion of Level 3 assets directly reflects how much of the balance sheet depends on internal models rather than market evidence.

Key signals: a growing Level 3 balance relative to total fair-value assets increases valuation uncertainty and earnings volatility risk. Watch for transfers between levels — assets moving from Level 2 to Level 3 often signal deteriorating market liquidity. Unrealized gains and losses on Level 3 positions flow through earnings or other comprehensive income, so large swings deserve scrutiny. For financial institutions, examine the sensitivity disclosures that show how Level 3 valuations change under alternative assumptions. Compare the fair value of debt against its carrying amount to gauge hidden leverage.
