Fair Value Accounting
An accounting framework that measures assets and liabilities at their current market value rather than original cost.
What is Fair Value Accounting?
Fair value accounting measures assets and liabilities at the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Under GAAP (ASC 820), fair value is estimated using a three-level hierarchy: Level 1 uses observable quoted market prices, Level 2 uses observable inputs other than quoted prices (such as similar assets), and Level 3 uses unobservable inputs based on management's own assumptions. Fair value accounting provides more timely and relevant information than historical cost, but introduces volatility in reported earnings and requires judgment for illiquid or complex instruments.
Example
A bank holds a portfolio of mortgage-backed securities. Under fair value accounting (mark-to-market), the portfolio must be reported at its current market value of $450 million, even if the bank paid $500 million for the securities. The $50 million unrealized loss is recognized either in earnings or in other comprehensive income depending on how the securities are classified under ASC 320. During financial crises, falling market prices can force institutions to recognize large losses on assets they intend to hold to maturity.
