ASC 820 Fair Value Measurement — Core Rule

Fair value is 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 (ASC 820-10-35-2). This is an exit price concept — it reflects what the market would pay, not what the asset cost or what the entity believes it is worth internally. ASC 820 establishes a single, consistent definition of fair value applied across all Topics that require or permit its use, replacing the patchwork of asset-specific guidance that existed before.


How ASC 820 Fair Value Measurement Works

  • The three-level fair value hierarchy: ASC 820 organizes inputs into three levels based on observability. Level 1 inputs are quoted prices in active markets for identical assets or liabilities — the most reliable signal available. When a quoted price exists as a Level 1 input, ASC 820 requires that price to be used without adjustment when measuring fair value (ASC 820-10-35-41C equivalent; see paragraph referenced at ASC 820 para.13.1). Level 2 inputs are observable but not quoted prices for identical items. Level 3 inputs are unobservable, requiring the entity to develop its own assumptions based on the best information available. The hierarchy is illustrated clearly: the primary question is whether a quoted price exists for an identical item in an active market; if not, the measurement moves to Level 2 or Level 3 depending on whether significant unobservable inputs are present.
  • Market participant assumptions: Fair value is measured from the perspective of a market participant, not the reporting entity. The transaction is assumed to occur in the principal market — or, in the absence of a principal market, the most advantageous market — for the asset or liability (ASC 820-10-35-6C). Entity-specific synergies, internal use assumptions, or proprietary intentions are excluded from the measurement.
  • Valuation techniques: ASC 820 permits three broad approaches — the market approach, the cost approach, and the income approach. Whichever technique (or combination of techniques) is selected, it must maximize the use of observable inputs and minimize reliance on unobservable inputs. The objective is always to estimate the price that market participants would agree on at the measurement date.
  • Highest and best use for nonfinancial assets: For nonfinancial assets, fair value reflects the asset's highest and best use as determined by market participants. This may differ from the entity's current use. For example, land currently used as a parking lot may have a highest and best use as a residential development — both scenarios must be considered to determine which premise of value achieves maximum benefit to market participants (ASC 820 para.8.2).
  • Unit of account: A fair value measurement applies to a specific asset or liability. The unit of account is determined by the Topic that requires or permits the measurement, except where ASC 820 provides otherwise (ASC 820-10 para.5.1). This matters particularly when a reporting entity holds a portfolio of instruments where individual versus portfolio-level measurement could produce different results.
  • Transaction price vs. fair value at initial recognition: The transaction price is not presumed to equal fair value at initial recognition. ASC 820 clarifies that differences between transaction price and fair value may result in Day 1 gains or losses, which must be recognized if the fair value is supported by observable market data or an accepted valuation technique (ASC 820 para.11.2).

ASC 820 Fair Value Measurement — Common Pitfalls

  • Using cost as a proxy for fair value without performing the required market-participant analysis — cost rarely equals exit price.
  • Ignoring the principal market requirement and defaulting to the most advantageous market when a principal market actually exists.
  • Misclassifying inputs in the hierarchy — a Level 2 measurement that relies on a single significant unobservable input should be classified as Level 3.
  • Applying blockage discounts to Level 1 instruments — quoted prices for Level 1 assets must be used at face value (P×Q) without portfolio-level adjustments.
  • Conflating highest and best use with current use for nonfinancial assets, particularly in industries where specialized assets are deployed below their market-optimal purpose.
  • Assuming transaction price equals fair value at inception without evaluating whether Day 1 gains or losses should be recognized.

ASC 820 Fair Value Measurement — Key Paragraphs

  • ASC 820-10-35-2 — Core definition: fair value is the exit price in an orderly transaction between market participants at the measurement date.
  • ASC 820-10-35-6C — Requires measurement to reference the principal market (or most advantageous market) for the asset or liability.
  • ASC 820 para.13.1 — Valuation techniques must maximize observable inputs; when a Level 1 quoted price exists, it is used without adjustment.
  • ASC 820 para.5.1 — Fair value measurement applies to a particular asset or liability; unit of account is set by the requiring Topic.
  • ASC 820 para.11.2 — Transaction price is not presumed to equal fair value, allowing for recognition of Day 1 gains and losses.
  • ASC 820 para.1.2 — ASC 820's principles are designed to increase consistency and comparability of fair value measurements across reporting entities and asset types.
