Key Points
- Stage 1 assets carry a twelve-month ECL allowance; Stage 2 and Stage 3 assets carry a lifetime ECL allowance.
- The trigger for moving from Stage 1 to Stage 2 is a significant increase in credit risk since initial recognition, not a breach of a fixed threshold.
- Most inspection findings flag inadequate qualitative overlays when the quantitative model alone does not capture deterioration.
- Stage 3 applies once a financial asset meets the definition of credit-impaired under IFRS 9 Appendix A.
What is Staging (IFRS 9 Stages 1, 2, 3)?
IFRS 9.5.5.1 requires the entity to recognise a loss allowance equal to twelve-month expected credit losses on initial recognition (Stage 1). If credit risk on that asset increases significantly after origination and the asset is not yet credit-impaired, the entity moves it to Stage 2, and the allowance jumps to lifetime ECL. IFRS 9.5.5.3 makes the assessment relative: the question is not whether the borrower is "high risk" in absolute terms, but whether its credit risk today is significantly worse than at the date the entity first recognised the asset.
Stage 3 applies when objective evidence of impairment exists. IFRS 9 Appendix A defines a credit-impaired financial asset by reference to events such as significant financial difficulty of the borrower, a breach of contract, a concession granted for economic or contractual reasons related to the borrower's distress, or the probability that the borrower will enter bankruptcy. Once an asset reaches Stage 3, the entity continues recognising lifetime ECL, but interest revenue is calculated on the net carrying amount (gross amount less loss allowance) rather than on the gross amount. That shift in interest accrual is the mechanical difference between Stage 2 and Stage 3 that auditors need to verify.
Worked example: Groupe Lefevre S.A.
Client: Belgian holding company, FY2024, consolidated trade receivables portfolio of EUR 31M across 420 counterparties, IFRS reporter.
Step 1 — Assign stages at reporting date
The credit risk team runs its staging model. Of the 420 counterparties, 376 show no significant increase in credit risk since invoice date. The model flags 38 counterparties (EUR 4.2M in receivables) where days-past-due exceed 30 days and external credit scores have deteriorated by more than two notches. Six counterparties (EUR 1.1M) are in formal insolvency proceedings or have confirmed inability to pay.
Step 2 — Calculate ECL per stage
For Stage 1 assets the entity applies a twelve-month PD of 0.8% and an LGD of 40%, producing a Stage 1 allowance of EUR 82,240 (EUR 25.7M x 0.8% x 40%). For Stage 2 the entity uses lifetime PDs ranging from 6% to 14% by counterparty, producing a Stage 2 allowance of EUR 378,000. For Stage 3 the entity recognises specific allowances totalling EUR 715,000 based on recoverable amounts estimated per counterparty.
Step 3 — Evaluate qualitative overlay
Management applies a EUR 45,000 qualitative overlay to Stage 1 for sector-specific risk in the construction sub-portfolio (EUR 3.8M) where payment patterns have weakened but the quantitative model has not yet triggered a stage transfer. The audit team evaluates whether this overlay is reasonable and whether any of these counterparties should instead be transferred to Stage 2.
Conclusion: Total ECL allowance of EUR 1,220,240 (EUR 127,240 Stage 1 including overlay, EUR 378,000 Stage 2, EUR 715,000 Stage 3), supported by documented staging criteria, model inputs, overlay rationale, and step-by-step audit trail.
Why it matters in practice
- The ECB's 2023 thematic review of IFRS 9 implementation across eurozone banks found that many entities relied exclusively on quantitative triggers (typically days-past-due thresholds) for stage transfers without incorporating qualitative indicators. IFRS 9.5.5.11 requires the entity to consider all reasonable and supportable information, including forward-looking macroeconomic data. A staging model that fires only on DPD is incomplete.
- Teams frequently test the ECL calculation itself but fail to audit the stage allocation as a separate assertion. If a counterparty is incorrectly parked in Stage 1 when it should be in Stage 2, the ECL is understated by the difference between twelve-month and lifetime losses. ISA 540.13(a) requires the auditor to evaluate whether the entity's method for the accounting estimate (here, the staging model) is appropriate under the applicable framework.

Frequently asked questions
Does staging apply to trade receivables under the simplified approach?
Entities that elect the IFRS 9.5.5.15 simplified approach for trade receivables without a significant financing component always measure the loss allowance at lifetime ECL. These receivables are not formally staged into Stages 1, 2, and 3. The three-stage model applies only when the entity uses the general impairment approach under IFRS 9.5.5.1–5.5.5.
How do I audit a stage transfer from Stage 2 back to Stage 1?
IFRS 9.5.5.5 permits an asset to move back to Stage 1 when credit risk improves to the point where SICR no longer exists. The auditor tests whether the entity's criteria for de-staging are consistent with its criteria for the original stage transfer, and whether the forward-looking information supports the conclusion that credit risk has returned to origination levels. ISA 540.18 requires evaluation of the reasonableness of assumptions underpinning the transfer.
When does an asset move from Stage 2 to Stage 3?
An asset moves to Stage 3 when it meets the definition of credit-impaired under IFRS 9 Appendix A. Typical triggers include borrower insolvency or a contractual breach exceeding 90 days. The key distinction from Stage 2 is objective evidence of impairment, not just increased risk. IFRS 9.5.5.3 and IFRS 9 Appendix A together govern this boundary.
