FAIR VALUE DISCLOSURES
The Company uses fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures.
Following is a discussion of the fair value hierarchy and the valuation methodologies used for assets and liabilities recorded at fair value on a recurring and nonrecurring basis and for estimating fair value for financial instruments not recorded at fair value.
Fair Value Hierarchy
Fair value measurements of assets and liabilities are categorized based on the following hierarchy:
Level 1 — Fair value determined based on quoted prices in active markets for identical assets or liabilities.
Level 2 — Fair value determined using significant observable inputs, such as quoted prices for similar assets or liabilities or quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability, or inputs that are derived principally from or corroborated by observable market data, by correlation or other means.
Level 3 — Fair value determined using significant unobservable inputs, such as pricing models, discounted cash flows, or similar techniques.
Estimation of Fair Value
The following table summarizes the fair value measurement methodologies, including significant inputs and assumptions, and classification of the Company’s assets and liabilities recorded at fair value on a recurring basis.

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.
