Fair Value Accounting

Fair value accounting is defined and governed in the United States by ASC 820, issued by the Financial Accounting Standards Board (FASB). The standard establishes a consistent framework for determining fair value across a wide range of financial and nonfinancial assets, from publicly traded securities to real estate held for investment.

The three-level hierarchy at the core of ASC 820 classifies fair value inputs by their observability. Level 1 inputs are quoted prices in active markets for identical assets — the most reliable form of evidence. Level 2 inputs are observable but indirect, such as quoted prices for similar assets or market-corroborated data like yield curves. Level 3 inputs are unobservable, relying on the entity's own assumptions about what market participants would use.

Level 3 valuations attract particular scrutiny from auditors, analysts, and regulators because they involve significant management judgment. A company with substantial Level 3 assets — private equity holdings, complex derivatives, or illiquid loans — provides less transparent financial information than one whose balance sheet is dominated by Level 1 instruments.

Fair value accounting interacts with multiple areas of GAAP. Impairment testing under ASC 350 (goodwill and intangibles) and ASC 360 (long-lived assets) compares carrying values to fair values. Pension accounting under ASC 715 requires plan assets to be measured at fair value. Business combination accounting under ASC 805 allocates the purchase price of an acquisition to acquired assets and liabilities at fair value.

Critics of fair value accounting argue that it introduces excessive income statement volatility for long-term assets that are never intended to be sold. Proponents counter that concealing economic losses through historical cost accounting creates systemic risk by allowing institutions to carry impaired assets at inflated values.
