# Fair Valuation Explained: ASC 820 and IFRS 13 Guide Published: 2026-04-19 Author: Warren Team URL: https://www.heywarren.com/blog/fair-value-accounting --- When a private equity fund marks down its startup stake by 20%, when a bank reports billions in losses on mortgage securities nobody is buying, or when a pension fund revalues its real estate portfolio, the same accounting concept is doing the heavy lifting: fair valuation. Yet "fair value" is one of the most misunderstood — and most contested — measurements in modern finance, blamed for amplifying the 2008 crisis and praised for forcing transparency that historical cost would have hidden for years. The problem is that fair value isn't a single number you look up. It's a framework. ASC 820 in the United States and [IFRS](https://www.ifrs.org/) 13 globally define it as an exit price observed (or estimated) in an orderly [transaction](/blog/what-is-a-transactions) between market participants at a specific date. Translating that definition into a defensible balance-sheet figure requires choosing a hierarchy level, picking a valuation approach, and disclosing your assumptions in painful detail. This guide walks through the fair value framework the way an [auditor](/blog/what-is-the-auditor), CFO, or analyst actually uses it: the formal definition, the three-level hierarchy, the three valuation approaches, where fair value applies versus where historical cost still rules, the 2008 mark-to-market controversy, and the modern frontier of crypto and ESG assets. Warren has helped thousands of investors, founders, and finance teams reason through valuation questions, and the playbook below distills what consistently matters. ## What Fair Value Actually Means Under ASC 820 and IFRS 13 Fair value is the price that would be received to sell an asset or paid to transfer a [liability](/blog/examples-liabilities) in an orderly transaction between market participants at the measurement date. Four words in that sentence carry the entire framework: exit, orderly, market participant, and date. Miss any one and you are measuring something else. **Exit price, not entry price.** Fair value asks what you would get if you sold today, not what you paid yesterday. A bond bought at par may now be worth 92 cents on the dollar. Fair value is 92, full stop, regardless of what you paid. **Orderly transaction.** This excludes forced or distressed sales. If the only quote you can get is from a vulture fund demanding a 40% liquidity discount because you must sell by Friday, that is not fair value. Fair value assumes a normal market exposure period. **Market participant perspective.** The buyer is a hypothetical third party with no special synergies or strategic value. Your view that "this asset is worth more to us" is irrelevant — that is investment value or strategic value, not fair value. **Measurement date.** Fair value is a snapshot. The same asset can have three different fair values across three quarter-end dates and all three be correct. ## The Fair Value Hierarchy: Levels 1, 2, and 3 ASC 820 and IFRS 13 require entities to classify every fair value measurement into a three-level hierarchy based on the observability of inputs. Level 1 is the most reliable (quoted prices in active markets), Level 2 uses observable inputs other than quoted prices, and Level 3 relies on unobservable inputs that require management judgment. The hierarchy drives both the rigor of the measurement and the depth of required disclosures. ![ASC 820 and IFRS 13 classify every fair value measurement into three levels based on input observability, from market quotes (Level 1) to management assumptions (Level 3).](data:image/svg+xml,%3Csvg%20xmlns%3D%22http%3A%2F%2Fwww.w3.org%2F2000%2Fsvg%22%20viewBox%3D%220%200%20600%20211%22%20width%3D%22600%22%20height%3D%22211%22%20role%3D%22img%22%3E%3Ctitle%3EHierarchy%3C%2Ftitle%3E%3Crect%20width%3D%22100%25%22%20height%3D%22100%25%22%20fill%3D%22%23f8fafc%22%2F%3E%3Crect%20x%3D%22220%22%20y%3D%2220%22%20width%3D%22160%22%20height%3D%2258%22%20rx%3D%228%22%20fill%3D%22%232563eb%22%2F%3E%3Ctext%20x%3D%22300%22%20y%3D%2254%22%20text-anchor%3D%22middle%22%20font-family%3D%22system-ui%2C-apple-system%2Csans-serif%22%20font-size%3D%2214%22%20font-weight%3D%22700%22%20fill%3D%22white%22%3EFair%20Value%20Hierarchy%3C%2Ftext%3E%3Cpath%20d%3D%22M%20300%2078%20L%20300%20105.5%20L%20120%20105.5%20L%20120%20133%22%20stroke%3D%22%23cbd5e1%22%20stroke-width%3D%222%22%20fill%3D%22none%22%2F%3E%3Crect%20x%3D%2240%22%20y%3D%22133%22%20width%3D%22160%22%20height%3D%2258%22%20rx%3D%228%22%20fill%3D%22white%22%20stroke%3D%22%230891b2%22%20stroke-width%3D%222%22%2F%3E%3Ctext%20x%3D%22120%22%20y%3D%22158%22%20text-anchor%3D%22middle%22%20font-family%3D%22system-ui%2C-apple-system%2Csans-serif%22%20font-size%3D%2213%22%20font-weight%3D%22600%22%20fill%3D%22%230f172a%22%3ELevel%201%3C%2Ftext%3E%3Ctext%20x%3D%22120%22%20y%3D%22176%22%20text-anchor%3D%22middle%22%20font-family%3D%22system-ui%2C-apple-system%2Csans-serif%22%20font-size%3D%2210%22%20fill%3D%22%2364748b%22%3EQuoted%20active%20market%20pric%E2%80%A6%3C%2Ftext%3E%3Cpath%20d%3D%22M%20300%2078%20L%20300%20105.5%20L%20300%20105.5%20L%20300%20133%22%20stroke%3D%22%23cbd5e1%22%20stroke-width%3D%222%22%20fill%3D%22none%22%2F%3E%3Crect%20x%3D%22220%22%20y%3D%22133%22%20width%3D%22160%22%20height%3D%2258%22%20rx%3D%228%22%20fill%3D%22white%22%20stroke%3D%22%230891b2%22%20stroke-width%3D%222%22%2F%3E%3Ctext%20x%3D%22300%22%20y%3D%22158%22%20text-anchor%3D%22middle%22%20font-family%3D%22system-ui%2C-apple-system%2Csans-serif%22%20font-size%3D%2213%22%20font-weight%3D%22600%22%20fill%3D%22%230f172a%22%3ELevel%202%3C%2Ftext%3E%3Ctext%20x%3D%22300%22%20y%3D%22176%22%20text-anchor%3D%22middle%22%20font-family%3D%22system-ui%2C-apple-system%2Csans-serif%22%20font-size%3D%2210%22%20fill%3D%22%2364748b%22%3EObservable%20inputs%20%28other%29%3C%2Ftext%3E%3Cpath%20d%3D%22M%20300%2078%20L%20300%20105.5%20L%20480%20105.5%20L%20480%20133%22%20stroke%3D%22%23cbd5e1%22%20stroke-width%3D%222%22%20fill%3D%22none%22%2F%3E%3Crect%20x%3D%22400%22%20y%3D%22133%22%20width%3D%22160%22%20height%3D%2258%22%20rx%3D%228%22%20fill%3D%22white%22%20stroke%3D%22%230891b2%22%20stroke-width%3D%222%22%2F%3E%3Ctext%20x%3D%22480%22%20y%3D%22158%22%20text-anchor%3D%22middle%22%20font-family%3D%22system-ui%2C-apple-system%2Csans-serif%22%20font-size%3D%2213%22%20font-weight%3D%22600%22%20fill%3D%22%230f172a%22%3ELevel%203%3C%2Ftext%3E%3Ctext%20x%3D%22480%22%20y%3D%22176%22%20text-anchor%3D%22middle%22%20font-family%3D%22system-ui%2C-apple-system%2Csans-serif%22%20font-size%3D%2210%22%20fill%3D%22%2364748b%22%3EUnobservable%20%2F%20management%E2%80%A6%3C%2Ftext%3E%3C%2Fsvg%3E)

**Level 1** covers identical assets traded in active markets — the closing price of an Apple share on NASDAQ, an on-the-run 10-year Treasury, a front-month gold futures contract. No model, no adjustments, just the quote. **Level 2** uses observable inputs other than Level 1 quotes: prices for similar (but not identical) assets, interest rate curves, credit spreads, implied volatilities. Most investment-grade corporate bonds, plain-vanilla interest rate swaps, and matrix-priced municipals live here. **Level 3** is where things get interesting. When inputs are unobservable, management must use its own assumptions about what a market participant would assume. Private company equity stakes, complex CDOs, [illiquid](/blog/illiquid) real estate, employee stock options, and bespoke derivatives typically classify as Level 3. Disclosure requirements are heaviest here for a reason — small input changes can swing valuations by tens of millions. ## The Three Valuation Approaches When market quotes are absent, you need a method. ASC 820 recognizes three valuation approaches, and entities are expected to use whichever is most appropriate given available data — sometimes more than one, with weighted reconciliation. Picking the wrong approach (or mixing them inconsistently across reporting dates) is one of the most common audit findings. ![Three valuation approaches](data:image/svg+xml;base64,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) The **market approach** uses prices from comparable market transactions — listing comps for a Manhattan office building, EBITDA multiples from a recent SaaS acquisition, or recent funding rounds for a private startup. It is intuitive but only as good as the comparability of the data. The **income approach** discounts expected future cash flows to present value. DCF models for operating businesses, Black-Scholes for stock options, and binomial trees for convertibles all live here. It dominates Level 3 because most illiquid assets eventually produce cash. The **cost approach** estimates the cost to replace the service capacity of the asset, less depreciation and obsolescence. It is rarely used outside of specialized assets like custom-built equipment, internal-use software, or unique infrastructure where neither markets nor cash flows give a clean signal. ## Where Fair Value Applies — and Where Historical Cost Still Rules Fair valuation does not blanket the balance sheet. US GAAP and IFRS apply it selectively, generally where market measurement provides the most decision-useful information. Trading securities, derivatives, and most financial instruments held at fair value through profit or loss get marked to market every reporting date. PP&E, inventory, and held-to-maturity debt usually stay at historical cost. Fair value typically applies to: - **Trading securities and FVTPL financial assets** — daily mark-to-market through earnings. - **Available-for-Sale (AFS) securities** — fair value through other comprehensive income. - **Derivatives** — always at fair value, with hedge accounting determining where gains/losses land. - **Investment properties** under IAS 40 (election available; mandatory disclosure if cost model used). - **Business combinations** — purchase price allocation values acquired assets and liabilities at fair value. - **Impairment tests** — goodwill, indefinite-lived intangibles, and long-lived asset groups. Historical cost still rules for: - **Property, plant, and equipment** under US GAAP (IFRS allows revaluation model but few use it). - **Inventory**, measured at lower of cost or [net realizable value](/blog/net-realizable-value). - **Held-to-maturity (HTM) debt securities**, carried at amortized cost as long as the entity has both intent and ability to hold to maturity. - **Most intangible assets with finite lives**, amortized from cost. The mixed-attribute model is one of the most criticized features of modern accounting — but it is also pragmatic. Marking a factory to fair value every quarter would produce noise, not signal. ## The 2008 Mark-to-Market Controversy When mortgage markets froze in 2008, banks holding subprime exposure faced a brutal feedback loop: forced sales depressed prices, depressed prices forced more write-downs, write-downs eroded capital, capital erosion forced more sales.

After Lehman's collapse, the SEC undertook a Congressionally mandated study and concluded in late 2008 that fair value accounting did not cause the crisis but did contribute to procyclicality. In April 2009, [FASB](https://www.fasb.org/) issued FSP FAS 157-4, providing additional guidance on measuring fair value when market activity has significantly decreased and recognizing when transactions are not orderly. Bank stocks rallied sharply on the release. The episode left a permanent mark on how Level 3 measurements are made and disclosed. ## Worked Example: A Private Equity Fund's Startup Stake A private equity fund holds a 5% stake in a Series C startup. The most recent 409A valuation, dated 14 months ago, implied a $50 million value for the stake. Two comparable companies in the same sector have raised down rounds in the last quarter at multiples roughly 20% lower than the original Series C terms. Public market multiples for SaaS peers have compressed about 18%. The fund must determine fair value at quarter-end. The fund applies the market approach using recent comparable financings, weighted with public peer multiple compression. The blended adjustment is approximately 20% downward, producing a Level 3 fair value of $40 million. Disclosure includes the valuation technique (market approach with calibration), key unobservable inputs (revenue multiple range 6.0x–8.0x; weighted average 7.0x), sensitivity (a 1.0x change in multiple moves fair value by ~$5.7 million), and the reconciliation of the opening to closing Level 3 balance. That disclosure package is not optional — ASC 820 and IFRS 13 mandate it specifically because Level 3 measurements depend on assumptions investors cannot independently verify. Auditors will probe the multiple selection, comparability of the precedent transactions, and any management override of the model. ## Validation, Audit, and the Critics' Case Material Level 3 positions are routinely validated by independent appraisers, third-party pricing services, and internal back-testing against eventual realization prices. Auditors test the design and operating effectiveness of valuation controls, recompute samples, and challenge significant assumptions. Despite this rigor, fair value attracts persistent criticism — for introducing earnings volatility, for procyclical capital effects, and for the irreducible subjectivity of Level 3. Critics highlight three concerns: fair value injects market noise into earnings that may not reflect long-term economics; mark-downs in stress periods force capital raises at the worst time; and Level 3 numbers are ultimately management estimates dressed in technical clothing. Defenders counter that fair value provides the most decision-useful information for investors, mirrors how risk managers actually think, and forces timely loss recognition rather than the "extend and pretend" pathology of historical cost. Common mistakes in practice include confusing fair value with intrinsic or strategic value, relying on stale Level 2 inputs after market conditions shift, underestimating Level 3 valuation uncertainty in disclosures, and inconsistently mixing valuation approaches across periods. Modern frontiers — cryptocurrency holdings, NFTs, carbon credits, and other ESG-linked assets — stress-test the framework further, often forcing entities into Level 2 or Level 3 with novel input sources and limited precedent. ## Authoritative Sources For deeper background and primary-source data on this topic, the following authoritative sources are useful starting points: - [AICPA](https://www.aicpa-cima.com/) - [Public Company Accounting Oversight Board](https://pcaobus.org/) ## Conclusion Fair valuation is the modern accounting framework for measuring assets and liabilities at the price a market participant would pay in an orderly transaction at the measurement date. Five things matter most: 1. **Definition discipline**: exit price, orderly transaction, market participant view, specific date. 2. **Hierarchy awareness**: Level 1 quotes, Level 2 observable inputs, Level 3 management assumptions — with disclosure depth that scales accordingly. 3. **Approach selection**: market, income, or cost — chosen based on data availability and applied consistently. 4. **Scope limits**: fair value applies to financial instruments, derivatives, and impairment testing, while PP&E and inventory typically stay at historical cost. 5. **Honest disclosure**: Level 3 measurements demand transparent inputs, sensitivity analysis, and rollforward reconciliations. The 2008 crisis showed both the costs of fair value (procyclicality, fire-sale marks) and its benefits (forced loss recognition, transparency). The framework survived because the alternative — historical cost everywhere — leaves investors flying blind. As crypto, ESG assets, and other novel instruments push the boundaries, the fair value framework continues to evolve, but the core principles of ASC 820 and IFRS 13 remain the global standard for how illiquid and liquid assets alike should be measured.
