Fair Value Measurements
The carrying amount of cash and cash equivalents in the Consolidated Balance Sheets, as well as the fair value, was $78 million at December 31, 2025 and $77 million at December 31, 2024. The fair value is categorized in Level 1 of the fair value hierarchy.
No material events occurred during 2025 requiring adjustment to the recognized balances of assets or liabilities which are recorded at fair value on a nonrecurring basis.
Long-term debt - We record the carrying amount of our long-term debt at historical cost, less deferred financing costs related to our outstanding senior notes and term loan. The estimated fair value of our long-term debt is shown in the table below and is based primarily on estimated current rates available to us for debt of the same remaining duration and adjusted for nonperformance risk and credit risk. The estimated fair value of our publicly traded outstanding senior notes included in long-term debt in the following table is based on the last quoted price closest to December 31 of each year. The fair value of our debt instruments is classified as Level 2 in the fair value hierarchy.

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.
