We have not transferred any investment securities between the three levels of the fair value hierarchy.
As of December 31, 2025, cash equivalents included $21.4 million of available-for-sale securities with contractual maturities of three months or less and short-term investments included $6.0 million of available-for-sale securities with contractual maturities of three months to one year. As of December 31, 2024, cash equivalents included $3.0 million of available-for-sale securities with contractual maturities of three months or less and short-term investments included $15.5 million of available-for-sale securities with contractual maturities of three months to one year. The money market funds as of December 31, 2025 and 2024 are included in cash and cash equivalents on the consolidated balance sheets.
The Company’s cash equivalents and short-term investment securities are classified within the fair value hierarchy as defined by authoritative guidance. The Company’s investment securities classified as Level 1 are valued using quoted market prices. The Company obtains the fair value of its Level 2 financial instruments from third-party pricing services. The pricing services utilize industry standard valuation models whereby all significant inputs, including benchmark yields, reported trades, broker/dealer quotes, issuer spreads, bids, offers, or other market-related data, are observable. The Company validates the prices provided by the third-party pricing services by reviewing their pricing methods and matrices
and obtaining market values from other pricing sources. After completing the validation procedures, the Company did not adjust or override any fair value measurements provided by these pricing services as of December 31, 2025 or 2024. The Company does not have any investments classified as Level 3.

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.
