Fair Value of Convertible Debt

The fair value, based on a quoted market price (Level 1), of the Company’s outstanding 0.75% Convertible Senior Notes due 2026 (the "2026 Notes") was approximately $79.0 million at December 31, 2025 and approximately $299.6 million at December 31, 2024.

The fair value, based on a quoted market price (Level 1), of the Company’s outstanding 0.75% Convertible Senior Notes due 2030 (the "2030 Notes") was approximately $618 million at December 31, 2025.

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.
