ASC 820 Fair Value Measurement: 2026 Practitioner Guide

ASC 820 is the single GAAP framework that governs how you measure and disclose fair value across derivatives, pension assets, goodwill impairment, purchase price allocations, and dozens of other contexts. If another standard requires or permits fair value, ASC 820 tells you how to get there.

Most explainers stop at the three-level hierarchy. This guide goes further: the five-step application framework, where companies actually go wrong, what ASU 2022-03 changed for lock-up shares (now fully effective for calendar-year filers), and the SEC comment letter themes that trip up even experienced teams.

Key takeaway: ASC 820 does not decide when you measure at fair value. It only governs how. The triggering standard (ASC 321, ASC 350, ASC 815, ASC 805) makes that call.

How GAAP Defines Fair Value Under ASC 820

Fair value under ASC 820 is an exit price, not an entry price. The standard defines it 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 exit-price concept matters in practice. The price you paid to acquire an asset (entry price) may differ from its fair value on day one, particularly for Level 3 assets where market evidence is thin. Oracle Corporation's Q1 FY2026 10-Q captures the operational implication precisely: when determining fair value, the entity considers "the principal or most advantageous market in which we would transact and consider assumptions that market participants would use when pricing the assets or liabilities, such as inherent risk, transfer restrictions and risk of nonperformance" (SEC EDGAR, Oracle 10-Q, August 31, 2025).

Three words anchor the definition and create the most common misapplications:

• Orderly transaction: not a forced liquidation or distressed sale.
• Market participants: hypothetical, knowledgeable, willing buyers and sellers in the principal market, not your entity's own assumptions.
• Measurement date: fair value is point-in-time. Yesterday's price does not automatically carry forward.

ASC 820 explicitly excludes certain measurements from its scope even though they use fair-value-like concepts: share-based payments under ASC 718, leasing transactions under ASC 842, and measurements such as net realizable value under ASC 330 or value in use. Misapplying ASC 820 to these is a recurring audit finding (PwC Viewpoint, Fair Value Measurements Guide).

The Five-Step Framework for Applying ASC 820

Applying ASC 820 correctly means working through five sequential decisions. PwC's fair value measurement guide describes this as the standard's operational structure, and Big-4 practitioners use it as the checklist for every measurement (PwC Viewpoint):

1. Identify the unit of account. What exactly is being measured? The unit of account is set by the standard that requires the fair value measurement, not by ASC 820 itself. For equity securities under ASC 321, the unit of account is the individual security. This step is where the contractual restriction question arises (see ASU 2022-03 below).

2. Identify the principal or most advantageous market. The principal market is the one with the greatest volume and level of activity for the asset or liability. If no principal market exists, use the most advantageous market, which maximizes the amount received for an asset or minimizes the amount paid to transfer a liability, after transportation costs but before transaction costs. Fair value is measured at the price in that market without deducting transaction costs.

3. Determine market participant assumptions. Fair value reflects what a hypothetical market participant would pay or receive, not what your entity would. Entity-specific synergies, proprietary restrictions on use, or internal assumptions that a market participant would not share cannot enter the measurement.

4. Select the appropriate valuation technique(s). ASC 820 recognizes three approaches. Entities may use more than one and must use whichever is appropriate for the circumstances:

1. Determine the fair value hierarchy level. Classify the measurement based on the lowest level of input that is significant to the overall measurement. This is not a free choice, it is a required conclusion that drives disclosure obligations.

ASC 820 Fair Value Hierarchy: Level 1, 2, and 3 Explained

The hierarchy ranks inputs by reliability, and the classification follows the least observable significant input. As Oracle's 10-Q states directly: "An asset's or a liability's categorization within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement" (SEC EDGAR, Oracle 10-Q).

Level 1: Quoted Prices in Active Markets

Level 1 inputs are quoted prices for identical assets or liabilities in active markets. This is the most reliable level because the price is directly observable with no adjustment. Oracle reported $3.051 billion of Level 1 assets as of August 31, 2025, consisting primarily of money market funds valued using quoted market prices in active markets.

The practical question: is the market active enough? A market is active when transactions occur with sufficient frequency and volume to provide ongoing pricing information. When trading thins, what looked like Level 1 may need to migrate to Level 2, and that reclassification requires disclosure.

Level 2: Observable Inputs Other Than Level 1

Level 2 inputs are observable, either directly or indirectly, but are not quoted prices for identical assets in active markets. They include:

• Quoted prices for similar (not identical) assets in active markets
• Quoted prices for identical or similar assets in markets that are not active
• Model inputs corroborated by observable market data (yield curves, credit spreads)

Oracle's Level 2 assets of $686 million as of August 31, 2025 included time deposits and derivatives valued using "non-binding market consensus prices corroborated by observable market data, quoted market prices for similar instruments, or pricing models, such as discounted cash flow techniques, with all significant inputs derived from or corroborated by observable market data including reference rate yield curves" (SEC EDGAR, Oracle 10-Q). Oracle's $89.3 billion of senior notes had an estimated fair value of $81.1 billion using Level 2 inputs, a discount of approximately 9.2% to face value reflecting current interest rate conditions.

Level 3: Unobservable Inputs

Level 3 inputs are supported by little or no market activity and rely on the entity's own assumptions about what market participants would use. Private equity investments, complex derivatives, and reporting units in goodwill impairment testing commonly land here.

ASC 820 requires entities to maximize observable inputs and minimize unobservable ones. That is not a preference; it is a requirement embedded in the hierarchy itself.

Key takeaway: Level 3 does not mean you can use whatever assumptions you prefer. It means observable inputs are unavailable, so you must construct what a market participant would assume, document that reasoning rigorously, and subject it to appropriate governance.

Unit of Account vs. Unit of Valuation

One of the most frequently misunderstood distinctions in ASC 820 practice: the unit of account (set by the triggering standard) and the unit of valuation (the level at which the technique is applied) can differ. Under the portfolio exception in ASC 820-10-35-18D, entities may measure a group of financial assets and liabilities on a net basis if certain criteria are met. Financial institutions and asset managers use this routinely, but it requires careful documentation to avoid audit findings.

What ASU 2022-03 Changed: Lock-Up Shares and Contractual Sale Restrictions

If your entity holds equity securities subject to lock-up agreements, SPAC-related restrictions, or other contractual sale prohibitions, ASU 2022-03 directly affects how you measure them. The amendment is now fully effective for public business entities for fiscal years beginning after December 15, 2023, meaning calendar-year 2024 filers have been subject to it since January 1, 2024. For all other entities, the effective date is fiscal years beginning after December 15, 2024 (FASB ASU 2022-03).

The FASB issued this update because SPAC transactions and other lock-up arrangements created significant diversity in practice. Some entities applied discounts of 10 to 30% or more to reflect the restriction; others did not. The FASB's conclusion was unambiguous:

"A contractual restriction on the sale of an equity security is not considered part of the unit of account of the equity security and, therefore, is not considered in measuring fair value. An entity cannot, as a separate unit of account, recognize and measure a contractual sale restriction." (FASB ASU 2022-03)

The rationale: the restriction is an attribute of the entity holding the security, not of the security itself. A market participant acquiring the security in a hypothetical exit transaction would not be bound by the seller's lock-up.

What this means in practice:

• No discount to fair value for contractual lock-up periods on equity securities.
• No separate liability or contra-asset recorded for the restriction's economic effect.
• Three new incremental disclosures are required for equity securities subject to contractual sale restrictions measured at fair value: (1) the fair value reflected in the balance sheet, (2) the nature and remaining duration of the restriction, and (3) the circumstances that could cause a lapse.

If your team adopted a discount methodology before ASU 2022-03 and has not updated its policy, that is a live compliance gap. The transition is applied prospectively, with special provisions for entities qualifying as investment companies under ASC 946.

Note: FASB issued a proposed ASU in July 2026 that would reverse ASU 2022-03 specifically for investment companies under ASC 946. If your entity is an investment company, see Finrep's analysis of FASB's July 2026 proposed ASU on investment company fair value and contractual sale restrictions.

ASC 820 Disclosure Requirements: What the SEC Actually Looks For

Disclosure is where most ASC 820 deficiencies surface. The SEC's Corp Fin staff has issued comment letters on fair value disclosures consistently, and the themes are predictable.

Required Disclosures by Level

For assets and liabilities measured at fair value on a recurring basis, ASC 820 requires:

• A table showing fair value amounts by hierarchy level at the balance sheet date.
• The valuation technique(s) and inputs used for Level 2 and Level 3 measurements.
• For Level 3 recurring measurements: a rollforward reconciling opening and closing balances, including total gains/losses in earnings, purchases, sales, issuances, and settlements, and transfers in and out of Level 3.
• For public entities: a narrative description of the sensitivity of Level 3 measurements to changes in unobservable inputs, including interrelationships between inputs.

For nonrecurring fair value measurements (goodwill impairment under ASC 350, long-lived asset write-downs under ASC 360, purchase price allocations under ASC 805), the disclosure requirements are similar but apply only in the period of the measurement. These are often treated as an afterthought, which is exactly why they attract SEC comments. For the ASC 350 intersection, see Finrep's ASC 350-20 goodwill impairment testing and disclosure requirements guide.

The ASC 825-10 Overlap Most Teams Miss

ASC 820 disclosure obligations extend beyond instruments carried at fair value. Under ASC 825-10, public entities must disclose the fair value of financial instruments not measured at fair value on the balance sheet, such as loans held for investment and long-term debt at amortized cost, using the ASC 820 hierarchy. Oracle's disclosure of the $81.1 billion estimated fair value of its senior notes using Level 2 inputs is a direct example of this requirement in practice.

Many non-financial companies overlook this. If you carry fixed-rate long-term debt at amortized cost, you still owe a Level 2 fair value disclosure in the notes.

Recurring SEC Comment Letter Themes

SEC Corp Fin staff has focused on three areas repeatedly:

1. Insufficient description of valuation techniques and significant unobservable inputs for Level 3. Boilerplate language like "discounted cash flow using unobservable inputs" does not satisfy the requirement. Staff expects the specific inputs (discount rate, revenue growth rate, terminal value multiple) and their ranges.

2. Inadequate sensitivity narrative. Public entities must explain how changes in unobservable inputs would affect the measurement, including interrelationships. A generic statement that "changes in assumptions could affect fair value" is not adequate.

3. Transfer disclosures. When instruments move between hierarchy levels, entities must disclose the amounts transferred and the reasons. Transfers should be recognized at the beginning or end of the reporting period, consistently applied, and the policy disclosed.

Level 3 Governance: What Auditors and the SEC Expect

The internal control environment around Level 3 valuations is as important as the valuation itself. For SOX-compliant public companies, Level 3 fair value estimates are a significant account that requires documented controls over the financial reporting process.

Auditors applying PCAOB standards will assess:

• Who owns the valuation model and what are their qualifications?
• Is there an independent review or validation of the model by someone not involved in its preparation?
• How are key assumptions (discount rates, growth rates, comparable transaction multiples) approved, and by whom?
• Is there a specialist involved, and if so, how did management evaluate the specialist's work?
• How are changes in methodology or inputs from prior periods identified, documented, and approved?

A common control deficiency: the same person who builds the Level 3 model also approves the final fair value conclusion. Separation of duties between model preparation and management review is a baseline expectation.

The governance trail should include contemporaneous documentation of the measurement date assumptions, the rationale for the selected valuation technique, and the approval sign-off. Reconstructing this documentation after the audit begins is a red flag.

For treasury-rate-sensitive Level 3 measurements, current market conditions add complexity. Finrep's Q2 2026 ASC 820 guide on rising Treasury yields covers how rate movements affect discount rate inputs in goodwill DCF and pension asset valuations.

ASC 820 vs. IFRS 13: What Multinationals Need to Know

For groups reporting under both US GAAP and IFRS, the good news is substantial convergence. IFRS 13, issued by the IASB in 2011 and effective from 2013, uses the same exit price definition, the same three-level hierarchy, and the same three valuation approaches as ASC 820 (IFRS Foundation, IFRS 13).

Key differences that require separate policy documentation:

• Scope: IFRS 13 applies to a broader range of measurements, including some not covered by ASC 820.
• Day-one gains on Level 3 instruments: The two frameworks handle the recognition of day-one differences between transaction price and fair value differently, which can affect financial institutions and entities with complex financial instruments.
• Disclosure nuances: Certain quantitative disclosure requirements differ in detail between the two standards.

For dual-reporter entities, the practical approach is to build a single valuation policy that satisfies both frameworks, then document the residual differences in a reconciliation memo. The frameworks are close enough that a single valuation model typically serves both, but the disclosure notes will differ.

FAQ: ASC 820 Fair Value Measurement

What is the ASC 820 definition of fair value? 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. It is an exit price concept, not the price paid to acquire an asset.

What does measuring fair value under ASC 820 require the reporting entity to determine? The entity must determine: the unit of account, the principal or most advantageous market, the market participant assumptions that would be used to price the asset or liability, the appropriate valuation technique(s), and the fair value hierarchy level based on the lowest level of significant input.

What is the ASC for the fair value option? The fair value option for financial instruments is governed by ASC 825-10 (the Fair Value Option subsection of ASC 825, Financial Instruments). When elected, the measurement of those instruments follows ASC 820.

How do Level 1, 2, and 3 inputs differ? Level 1 uses quoted prices in active markets for identical assets or liabilities. Level 2 uses observable inputs other than Level 1 prices, including prices for similar assets or model inputs corroborated by market data. Level 3 uses unobservable inputs based on the entity's own assumptions about market participant behavior. Classification follows the lowest level of input that is significant to the measurement.

Does ASU 2022-03 apply to all entities holding restricted equity securities? Yes. It applies to all entities with investments in equity securities measured at fair value that are subject to contractual sale restrictions. Public business entities were required to adopt it for fiscal years beginning after December 15, 2023. All other entities for fiscal years beginning after December 15, 2024. Note that FASB has proposed reversing this guidance specifically for investment companies under ASC 946.

What are the most common SEC comment letter issues on ASC 820 disclosures? The three recurring themes are: insufficient specificity in describing Level 3 valuation techniques and unobservable inputs, inadequate sensitivity narratives for Level 3 measurements, and incomplete disclosure of transfers between hierarchy levels including the reasons for the transfer.

Does ASC 820 apply to instruments not carried at fair value on the balance sheet? Not directly, but ASC 825-10 requires public entities to disclose the fair value of financial instruments carried at amortized cost (such as long-term debt) using the ASC 820 hierarchy. This disclosure obligation is frequently overlooked by non-financial companies.
