Fair Value Measurements
We perform fair value measurements in accordance with ASC 820, Fair Value Measurement, which establishes three levels of inputs that we use to measure fair value:
Level 1: quoted prices in active markets for identical assets or liabilities.
Level 2: observable inputs (e.g., spot rates and other data from third-party pricing vendors for our derivative instruments, credit rating and current prices of similar debt instruments that are publicly traded for our debt instruments) other than quoted market prices included within Level 1 that are observable, either directly or indirectly, for the assets or liabilities.
Level 3: unobservable inputs to the valuation methodology that are significant to the measurement of the fair value of assets or liabilities, including indicative pricing from third parties for similar instruments and asset-specific yield adjustments for elements such as credit risk.
The fair values of certain financial assets and liabilities as of December 31 were as follows (in millions):

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.
