Fair Value Measurements
At December 31, 2021, the Company had no financial assets or liabilities measured at fair value on a recurring basis. At December 31, 2020, the Company had no financial assets measured at fair value on a recurring basis. The Company measured the fair value of its interest rate swaps, its only liability measured at fair value on a recurring basis at December 31, 2020, using the fair value hierarchy described in Note 2. At December 31, 2020, the fair value of the interest rate swaps was $11.8 million, which was determined using Level 2 inputs (significant unobservable inputs) under the fair value hierarchy.
The estimated fair value of the Company’s long-term debt compared with its carrying amount is presented below (amounts in millions):

Aggregate fair value$2,887 $2,936 
Aggregate carrying amount2,854 2,902 
The estimated fair value of the Company’s long-term debt is based on quoted market prices from various banks for similar instruments, which is considered a Level 2 input under 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.
