FASB ASU 2023-08: Fair-Value Crypto Accounting

This is the standard that rewrote the US-GAAP balance sheet for crypto. ASU 2023-08 created Subtopic 350-60, ending the cost-less-impairment treatment that left holdings economically meaningless and putting in-scope crypto at fair value through net income from fiscal years beginning after 15 December 2024. This article is the US-GAAP hub for that change: the criteria-based scope test, the modified-retrospective transition, and the disclosure package. The companion IFRS treatment, where no equivalent mandate exists, sits under IAS 38 and crypto.

What changed, in brief

• ASU 2023-08 created Subtopic 350-60. In-scope crypto is measured at fair value, with changes through net income each period.
• Effective for fiscal years beginning after 15 December 2024, including interim periods (a calendar-year entity applies it from 1 January 2025). Early adoption is permitted.
• Scope is criteria-based: intangible, fungible, on a distributed ledger, no enforceable rights to underlying, not entity-issued. It captures assets like BTC and ETH and excludes NFTs, wrapped tokens, and own-issued tokens.
• Transition is modified-retrospective: a cumulative-effect adjustment to opening retained earnings (carrying amount vs fair value at the prior annual period-end).
• Disclosure covers each significant asset (name, cost basis, fair value, units), an aggregate for non-significant holdings, and contractual sale restrictions.
• The standard governs scope, subsequent measurement, presentation, and disclosure. It does not address recognition, initial measurement, or derecognition.

What it replaces, and why it matters

Before ASU 2023-08, US GAAP had no crypto-specific standard, so crypto was an indefinite-lived intangible asset: held at cost, tested for impairment, written down when impaired and never written back up. In a volatile or rising market that produced a balance sheet that understated holdings and an income statement of impairment-only noise. ASU 2023-08 makes measurement symmetric — fair value each period, both gains and losses in net income — so the financials track the economics (see crypto impairment vs fair value).

It is also narrow by design. The standard addresses scope, subsequent measurement, presentation, and disclosure. It deliberately does not address recognition, initial measurement, or derecognition — those still follow other US GAAP.

The scope test

An asset is in scope of Subtopic 350-60 only if all of these hold. It:

• meets the definition of an intangible asset;
• is fungible;
• is created or resides on a distributed ledger using cryptography;
• does not give the holder enforceable rights to or claims on underlying goods, services, or other assets;
• is not created or issued by the reporting entity or its related parties.

That captures assets such as Bitcoin and Ether. It excludes (examples, not an exhaustive list): non-fungible tokens, wrapped tokens that convey a claim, and an entity's own-issued token. The "no enforceable rights to underlying" criterion is why many stablecoins fall out of scope (see stablecoin accounting treatment).

Measurement and presentation

In-scope crypto is measured at fair value each reporting period under ASC 820, with changes in fair value recognised in net income. Crypto assets are presented separately from other intangible assets on the balance sheet, and fair-value changes are presented separately from changes in the carrying amount of other intangibles on the income statement.

The transition: modified-retrospective

Adoption is modified-retrospective. You record a cumulative-effect adjustment to the opening balance of retained earnings (or the appropriate equity component) as of the beginning of the annual reporting period in which you adopt. The adjustment equals the difference between carrying amount and fair value of the crypto at the end of the prior annual reporting period. Comparative prior periods are not restated.

The disclosures

For both interim and annual periods:

Significance is assessed on fair value. A reconciliation of opening-to-closing crypto holdings (additions, dispositions, gains, losses) is also required annually.

Practical guidance

1. Run the scope test asset-by-asset — BTC/ETH in; NFTs, wrapped, own-issued, claim-bearing stablecoins need separate analysis.
2. Compute the transition adjustment off prior-annual-period-end fair value; book it to opening retained earnings.
3. Stand up a fair-value process (ASC 820 principal market, period-end pricing) for every reporting date, including interim.
4. Build the disclosure dataset — per-asset name/cost/FV/units and the restricted-holdings detail — before close, not at audit.
5. Brief stakeholders on earnings volatility — net income now moves with crypto price; this changes covenants and KPIs.

Choosing a tool for 350-60 reporting

A subledger does not change what the standard requires, but it is where the fair-value figures and the transition adjustment actually get produced. If you are selecting or configuring one — Cryptio and Bitwave are common choices — check that it can:

• maintain a cost basis and a period-end fair value per asset, for interim periods as well as annual;
• source fair value from a principal market you can defend under ASC 820, rather than an undocumented aggregate feed;
• compute the modified-retrospective transition figure off prior-annual-period-end fair value;
• output the 350-60 disclosure dataset (the significant-asset table, the roll-forward, and the restricted-holdings detail) as exportable records.

The standard is the framework; the subledger is the evidence your auditor tests against.

How Wag3s fits in

Wag3s Ledger keeps a per-asset cost basis and period-end fair value with an audit trail, computes the modified-retrospective transition adjustment, and outputs the ASU 2023-08 disclosure dataset — the significant-asset table, the roll-forward, and the restricted-holdings note. Scope determination under 350-60 is asset-specific and judgemental, so Ledger is built to produce the figures and the supporting trail that your auditor and accountant review, not to replace that judgement. See the Ledger product page and the Wag3s for accountants page.
