Fair value hierarchy

The fair value hierarchy ranks inputs as Level 1 (quoted prices in active markets), Level 2 (other observable inputs) or Level 3 (unobservable inputs); a measurement takes the level of its lowest significant input.

CORAA TeamUpdated November 5, 2026

Definition

ASC 820 defines fair value as 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. The hierarchy classifies inputs: Level 1 are quoted prices in active markets for identical assets or liabilities that the entity can access; Level 2 are inputs other than Level 1 that are observable, directly or indirectly; Level 3 are unobservable inputs. A measurement is categorized in its entirety based on the lowest-level input significant to the measurement.

Why it matters in an audit or review

Higher levels need more audit evidence about management's assumptions and models. Auditors vouch Level 1 prices to independent sources, evaluate Level 2 vendor pricing, and often use a specialist for Level 3. Nonpublic entities have scaled-back disclosure requirements under ASC 820-10-50.

Example

(Illustrative) A company holds a publicly traded mutual fund (Level 1), a corporate bond priced from observable quotes of similar bonds (Level 2), and an interest in a private company valued with a discounted cash flow (Level 3).

Common mistakes

  • Classifying vendor-supplied prices as Level 1 without checking activity.
  • Omitting the valuation technique disclosures.
