Other Debt Obligations
The following outstanding debt obligations are reflected in the Company's consolidated balance sheet at carrying value since the Company did not elect to remeasure the debt obligations to fair value at the end of each reporting period. The carrying values of these debt obligations approximate fair value due to the short-term maturity of these debt obligations.

There were no transfers between Level 1 and Level 2 of the fair value hierarchy in 2025 and 2024.
Cash, accounts receivable, accounts payable, and accrued expenses are generally carried on the cost basis, which management believes approximates fair value due to the short-term maturity of these instruments.

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.
