ASBJ 10
Revised 2026
Accounting Standard for Financial Instruments
Accounting Standard for Financial Instruments (Revised 2026) is part of the Japan GAAP framework.
Revised Standard (Effective 2026)
ASBJ released an exposure draft of proposed amendments to Statement No. 10 (Exposure Draft of Statement No. 89) on February 27, 2026, alongside Implementation Guidance on expected credit loss accounting for financial assets. This standard describes the confirmed revised framework.
1
Conceptual Framework Linkage
A genuinely major step ending J-GAAP's long IAS-39-era stasis
As discussed in the companion ASBJ Statement No. 10 poster, J-GAAP's financial instruments impairment model has LONG remained conceptually CLOSER to the OLD, superseded IAS 39 incurred-loss approach than to IFRS 9's CURRENT expected credit loss (ECL) model. The 2026 exposure draft PROPOSES a GENUINELY MAJOR change: introducing an EXPECTED CREDIT LOSS model for financial ASSETS – the FIRST real step toward CLOSING this long-standing gap.
2
Scope of the Proposed Revision
Impairment of financial assets, with companion guidance changes
The PROPOSED amendments apply to the IMPAIRMENT of financial ASSETS within scope of ASBJ Statement No. 10 – issued ALONGSIDE a DEDICATED new Implementation Guidance specifically on "Accounting for Expected Credit Losses on Financial Assets," plus CONSEQUENTIAL amendments to related fair value disclosure guidance and PRACTICAL/transferred guidance documents.
3
THE HEADLINE CHANGE – Introducing an Expected Credit Loss Model
Forward-looking loss estimation, replacing the old incurred-loss trigger
The PROPOSED model REQUIRES recognising an ALLOWANCE for EXPECTED credit losses – estimated based on FORWARD-LOOKING information about FUTURE default risk – RATHER than waiting for a SPECIFIC, OBSERVABLE loss event (the OLD "incurred loss" trigger) before recognising IMPAIRMENT. This is CONCEPTUALLY the SAME fundamental shift IFRS 9 introduced INTERNATIONALLY when it REPLACED IAS 39 – recognising loss allowances EARLIER, based on EXPECTED future outcomes RATHER than confirmed PAST events.
4
Ending the Long-Standing Lag Behind IFRS 9
Genuinely closing one of J-GAAP's most cited divergences
This proposed revision represents the FIRST substantial step toward CLOSING the divergence FLAGGED throughout this poster series – J-GAAP's financial instruments standard REMAINING anchored to an "old IAS 39"-style APPROACH for an EXTENDED period AFTER IFRS itself moved on to IFRS 9. If FINALISED substantially as PROPOSED, this would represent a genuinely SIGNIFICANT convergence MILESTONE, alongside Revenue Recognition (No. 29), Fair Value Measurement (No. 30), and Leases (No. 34) as areas where J-GAAP has MOVED, or is MOVING, toward alignment with the CURRENT generation of international standards.
5
What Likely Stays the Same – the Classification Categories
A targeted impairment reform, not necessarily a full classification overhaul
Based on the CONFIRMED scope of the exposure draft (impairment-focused, with a DEDICATED expected-credit-loss implementation guidance document), this revision APPEARS TARGETED primarily at the IMPAIRMENT/measurement-of-loss question, RATHER than necessarily a FULL replication of IFRS 9's ENTIRE classification architecture (business model and cash flow characteristics testing). The EXISTING four-category classification structure (trading, held-to-maturity, available-for-sale, subsidiary/affiliate investments – see the companion ASBJ Statement No. 10 poster) may WELL persist ALONGSIDE the new expected credit loss impairment approach, though this should be CONFIRMED against the finalised standard.
6
Companion Amendments – Related Party Disclosures and Revenue Recognition
A broader, coordinated exposure draft package
The SAME exposure draft package ALSO proposed amendments to ASBJ Statement No. 11 (Related Party Disclosures), ASBJ Statement No. 29 (Revenue Recognition), and ASBJ Statement No. 34 (Leases) – INDICATING this was a genuinely BROAD, coordinated standard-setting cycle addressing MULTIPLE related topics SIMULTANEOUSLY, rather than an ISOLATED financial instruments project.
7
Worked Example – the Old Incurred-Loss Approach
Waiting for a specific loss event before recognising impairment
Example: A receivable under the pre-2026 model
A company holds a ¥100,000,000 trade receivable from a customer showing early signs of financial difficulty, but with no confirmed default event yet.
Under the OLD incurred-loss approach, NO impairment is recognised UNTIL a SPECIFIC loss event (e.g. missed payment, formal distress signal) OCCURS – the receivable REMAINS at its full ¥100,000,000 carrying amount UNTIL such a TRIGGERING event is OBSERVED.
8
Worked Example – the Proposed Expected Credit Loss Approach
Recognising a forward-looking allowance earlier
Example: The same receivable under the proposed model
Continuing the prior example, under the PROPOSED expected credit loss model, the company estimates a 5% probability-weighted expected loss on the SAME receivable, based on forward-looking information about the customer's deteriorating position.
The company recognises an EXPECTED CREDIT LOSS allowance of ¥100,000,000 × 5% = ¥5,000,000 – EARLIER, and WITHOUT waiting for a CONFIRMED default event – REFLECTING the FORWARD-LOOKING nature of the proposed model, a MEANINGFUL change from the prior incurred-loss approach.

Relationship to IAS/IFRS and US GAAP
Comparison – J-GAAP (proposed) vs IFRS 9 and US GAAP's CECL model
FeatureJ-GAAP (proposed, 2026)IFRS 9 / US GAAP (CECL, ASC 326)
Impairment triggerExpected (forward-looking) loss, proposedExpected (forward-looking) loss – converged in principle
Old incurred-loss modelBeing REPLACED by this proposalAlready replaced (IFRS 9 in 2018; CECL under US GAAP from 2020)
If FINALISED as proposed, this would represent J-GAAP FINALLY catching up to a reform BOTH IFRS and US GAAP completed SEVERAL YEARS earlier – closing one of the MOST frequently cited J-GAAP divergence points discussed throughout this poster series.

Quick-Reference Glossary
Expected credit loss (ECL)
A forward-looking, probability-weighted estimate of credit losses, recognised before a specific loss event is confirmed, replacing the older incurred-loss trigger.
Incurred loss model (legacy approach)
The prior J-GAAP approach recognising impairment only once a specific, observable loss event has occurred.
