The incurred loss model under IAS 39 had one fundamental flaw: it waited for evidence of loss before recognising one. Banks were sitting on deteriorating loan portfolios with no provisions because no objective event had technically occurred yet. The 2008 financial crisis exposed this for what it was: a model that was structurally too late.

IFRS 9's Expected Credit Loss model does not wait. From the moment a financial asset is recognised, a provision for expected losses is required. The question is no longer "has a loss event occurred?" It is "how much loss do we expect, and over what horizon?"

This post covers the ECL model in full: the three-stage framework, the general approach, the simplified approach for trade receivables, the provision matrix, what constitutes a significant increase in credit risk, credit-impaired assets, and write-offs. Post 20 covers the Indian banking context specifically.

Scope of the ECL Model

The ECL impairment model applies to:

• Financial assets measured at amortised cost
• Financial assets measured at FVOCI (debt instruments)
• Lease receivables under IFRS 16
• Contract assets under IFRS 15
• Loan commitments not measured at FVTPL
• Financial guarantee contracts not measured at FVTPL

It does not apply to equity instruments (no contractual cash flows to be impaired) or financial assets at FVTPL (fair value changes already capture credit deterioration in the P&L).

The Three-Stage Framework: General Approach

Stage 1: Performing Assets (12-Month ECL)

At initial recognition, every in-scope financial asset enters Stage 1. The loss allowance equals 12-month ECL: the expected credit losses resulting from default events possible within 12 months of the reporting date.

Interest income is recognised on the gross carrying amount (before deducting the loss allowance).

The 12-month ECL is not the loss expected in the next 12 months. It is the portion of lifetime ECL attributable to default events that could occur in the next 12 months, weighted by the probability of those defaults occurring.

Stage 2: Significant Increase in Credit Risk (Lifetime ECL)

When credit risk has increased significantly since initial recognition, the asset moves to Stage 2. The loss allowance increases to lifetime ECL: expected credit losses over the entire remaining life of the instrument.

Interest income continues to be recognised on the gross carrying amount.

The jump from 12-month to lifetime ECL is the most operationally consequential transition in the model. A large corporate loan moving from Stage 1 to Stage 2 can multiply the provision several times over.

Stage 3: Credit-Impaired (Lifetime ECL, Net Interest)

When objective evidence of impairment exists, the asset is credit-impaired and moves to Stage 3. Lifetime ECL continues to apply. The critical change: interest income is now recognised on the net carrying amount (gross carrying amount minus loss allowance), not the gross amount.

This reduces reported interest income on impaired assets, reflecting the economic reality that full interest collection is uncertain.

Significant Increase in Credit Risk: The Stage 1 to Stage 2 Trigger

Identifying when credit risk has increased significantly is the most judgment-intensive aspect of the ECL model. IFRS 9 provides guidance but does not define a bright line.

Rebuttable presumption: there is a rebuttable presumption that credit risk has increased significantly when contractual payments are more than 30 days past due. This is a floor, not a ceiling. An entity with better forward-looking information must act on it before 30 days past due.

Indicators of significant increase in credit risk:

• Significant deterioration in internal or external credit ratings
• Significant adverse change in the borrower's business, financial, or economic conditions
• An actual or expected breach of covenants
• Significant increase in credit spreads on the borrower's debt
• Change in borrower's payment behaviour (payments becoming irregular even if not yet overdue)
• Macroeconomic changes that affect the borrower's sector
• Forbearance being granted (restructuring, deferral of payments)

The low credit risk exemption: if a financial asset has low credit risk at the reporting date, an entity may assume credit risk has not increased significantly since origination without detailed assessment. Low credit risk is broadly equivalent to investment-grade status.

Indian context for corporate lenders: HDFC Bank assessing a term loan to a steel company needs to monitor sector-specific indicators, commodity prices affecting the borrower's margins, leverage ratios at each reporting date relative to origination, and any covenant compliance issues. If the steel company's EBITDA coverage falls materially below origination levels even before any payment defaults, the loan should migrate to Stage 2. Waiting for 30 days past due is the backstop, not the trigger.

Measuring ECL: The Three Components

ECL = PD × LGD × EAD, discounted at the original EIR.

Probability of Default (PD): the probability that the borrower defaults within the relevant time horizon (12 months for Stage 1, remaining life for Stages 2 and 3). Must be forward-looking, not just historical.

Loss Given Default (LGD): the percentage of the exposure the lender expects to lose if default occurs, after accounting for recoveries (collateral, guarantees, restructuring). A secured mortgage has a lower LGD than an unsecured personal loan.

Exposure at Default (EAD): the outstanding amount at the point of default. For term loans with a fixed amortisation schedule, this is straightforward. For revolving credit facilities (overdrafts, credit cards), EAD must estimate how much of the undrawn commitment will be drawn before default.

Forward-looking information: PD, LGD, and EAD must all incorporate forward-looking information. Historical loss rates alone are not sufficient. An entity must adjust for current conditions and reasonable forecasts of future economic conditions, including multiple macroeconomic scenarios weighted by probability.

This is operationally demanding. A bank needs macroeconomic models, scenario analysis, and forecasting capabilities to meet IFRS 9's ECL requirements properly. For non-financial entities with simple receivable portfolios, the requirement is lighter but still present.

Worked Example: General Approach ECL for a Corporate Loan

Bajaj Finance has a term loan outstanding to a mid-sized manufacturer. Details:

• Outstanding balance: Rs. 50 crore
• Remaining term: 3 years
• Original EIR: 12%
• No security

At year end, Stage 1 assessment:

Loss allowance: Rs. 0.42 crore. Recognised in profit or loss. Deducted from the gross carrying amount on the balance sheet.

Six months later: credit risk increases significantly. Stage 2.

The manufacturer reports a covenant breach. Bajaj Finance determines lifetime ECL is required.

Loss allowance increases from Rs. 0.42 crore to Rs. 4.30 crore. Additional impairment charge in P&L: Rs. 3.88 crore. Significant income statement impact from a single stage migration.

The Simplified Approach: Trade Receivables and Contract Assets

For trade receivables and contract assets that do not contain a significant financing component, the simplified approach is mandatory. No staging assessment. No 12-month ECL. Lifetime ECL is recognised from day one.

For trade receivables with a significant financing component, and for lease receivables, the entity can choose between the general approach and the simplified approach.

The simplified approach removes the Stage 1/Stage 2 distinction. Every receivable carries a lifetime ECL allowance from initial recognition. In practice, for short-term receivables (30-day or 60-day credit terms), lifetime ECL and 12-month ECL are essentially the same. The simplification is operationally valuable without materially changing the numbers.

The Provision Matrix

IFRS 9 suggests the provision matrix as a practical expedient for calculating lifetime ECL on trade receivables. It groups receivables by shared characteristics (geography, customer type, credit rating) and applies historical default rates adjusted for forward-looking factors to each ageing bucket.

Worked example: Provision matrix for an Indian FMCG manufacturer

A manufacturer has the following trade receivables at 31 March 2026:

Total loss allowance: Rs. 6.78 crore. Recognised as impairment expense in P&L if opening balance was nil, or as the movement from prior year balance.

The forward-looking adjustment is critical. If the manufacturer's customer base is concentrated in a sector facing stress (for example, small textile manufacturers during a downturn), historical rates alone underestimate expected losses. The adjustment incorporates available economic information. It is not optional.

Segmentation matters. A manufacturer with customers across retail, government, and export should not apply a single matrix to the entire receivable book. Government receivables have different default characteristics than small retailers. Segment, then apply separate matrices.

Credit-Impaired Assets: Stage 3

A financial asset is credit-impaired when objective evidence of impairment exists. IFRS 9 provides indicators:

• Significant financial difficulty of the borrower
• Breach of contract, including default or delinquency in payments
• The lender has granted the borrower a concession that would not otherwise be considered (restructuring, rate reduction)
• It is probable the borrower will enter bankruptcy or other financial reorganisation
• Disappearance of an active market for the financial asset due to financial difficulties
• Purchase or origination of a financial asset at a deep discount that reflects incurred credit losses

The 90-day past due threshold is a rebuttable presumption for credit impairment, consistent with Stage 3. It can be rebutted if the lender has information showing that the past due status does not reflect genuine impairment (for example, administrative processing delays).

Indian context: An NPA (non-performing asset) under RBI's IRAC norms is broadly equivalent to Stage 3 under Ind AS 109. An asset classified as NPA by a bank is credit-impaired for IFRS 9 purposes. The key difference is that IFRS 9 may require Stage 3 classification earlier than RBI's 90-day NPA threshold if objective evidence of impairment exists before 90 days past due.

Interest recognition on Stage 3 assets:

Once credit-impaired, interest income is calculated on the net carrying amount. The mechanics:

• Gross carrying amount: Rs. 100 crore
• Loss allowance: Rs. 60 crore
• Net carrying amount: Rs. 40 crore
• EIR: 12%
• Interest income: Rs. 40 crore × 12% = Rs. 4.8 crore (not Rs. 12 crore on the gross amount)

This reduces reported interest income on impaired loans. For a bank with a large NPA portfolio, the shift from Stage 2 to Stage 3 has a compounding effect on income: the provision increases and interest income falls simultaneously.

Write-Offs

A financial asset (or part of it) is written off when there is no reasonable expectation of recovery. Write-off reduces the gross carrying amount and the loss allowance simultaneously. It has no net income statement impact at the point of write-off (the loss was already recognised when the provision was raised).

Write-off does not mean the legal claim is extinguished. An entity can continue pursuing recovery after write-off. Any subsequent recovery is recognised as a reversal of impairment in profit or loss.

IFRS 9 requires write-off when recovery is no longer reasonably expected. This is not a management discretion call. Keeping a fully provided asset on the gross balance indefinitely, without write-off, overstates both assets and the loss allowance.

Indian banking practice: Indian banks historically delayed write-offs longer than IFRS 9 intends. Under old GAAP, write-offs had tax implications and affected regulatory capital ratios differently than provisioning. Under Ind AS 109, the IFRS 9 write-off standard applies, though RBI's regulatory reporting requirements for written-off accounts continue separately.

---

Reversals of ECL

If credit quality improves and an asset previously in Stage 2 returns to Stage 1, the loss allowance is reduced. The reduction is recognised as a gain in profit or loss. The allowance cannot be reduced below the amount required for the current stage.

Reversals are not optional. If credit risk reduces, the allowance must be reduced to reflect that. Keeping an allowance at Stage 2 levels when the asset qualifies for Stage 1 overstates provisions and understates earnings.

---

ECL on Loan Commitments and Financial Guarantees

Loan commitments not at FVTPL require ECL recognition. The ECL is measured over the maximum contractual period during which the entity is exposed to credit risk.

For an undrawn revolving credit facility, EAD must estimate how much will be drawn before potential default. This requires a credit conversion factor (CCF), which estimates the expected drawdown percentage.

Financial guarantee contracts require ECL recognition from initial recognition. The ECL represents the expected payments to reimburse the holder for credit losses on the guaranteed instrument.

---

Interaction with Collateral

ECL must reflect the effect of collateral and credit enhancements. Collateral does not affect PD but reduces LGD: if the borrower defaults, the lender recovers value from the collateral.

The collateral value must be realistic, reflecting forced-sale discounts, enforcement costs, and the time lag between default and realisation. A property worth Rs. 100 crore at market value may yield Rs. 60 crore in a forced sale after legal costs and delays. The LGD calculation uses Rs. 60 crore, not Rs. 100 crore.

For Indian secured lenders, particularly those with real estate collateral, the forced-sale discount and enforcement timeline assumptions are major drivers of LGD estimates. SARFAESI recovery timelines and DRT proceedings are notoriously long in India. A realistic LGD for an unsecured real estate collateral position must reflect these enforcement realities.

Ind AS 109 vs IFRS 9: ECL Differences

The higher-of rule between RBI norms and Ind AS 109 ECL is the most operationally significant difference for Indian banks. In practice, RBI's sector-specific provisioning requirements (such as higher provisions for commercial real estate, restructured accounts, and certain stressed sectors) often exceed Ind AS 109 ECL for specific portfolios. The bank recognises the higher amount.

What Big 4 Auditors Focus On

SICR assessment completeness. Auditors test whether Stage 1 assets that should have migrated to Stage 2 have been correctly identified. This is the highest-risk area in ECL audits. The test involves examining credit monitoring data, covenant compliance reports, and early warning indicators against the entity's SICR policy.

Forward-looking information adequacy. Auditors challenge whether macroeconomic scenarios are current, whether scenario weights are reasonable, and whether the scenarios are adequately severe to capture tail risks. A provision matrix using only historical loss rates with no forward-looking adjustment will be challenged.

Model validation. For banks with sophisticated ECL models, auditors engage credit risk specialists to independently validate PD, LGD, and EAD models. Model bias, data quality issues, and overly optimistic assumptions in any of the three components are audit risks.

Collateral valuation. Real estate and other asset collateral valuations underpinning LGD estimates are tested against independent appraisals, market data, and forced-sale discount assumptions.

Dip IFRS Exam Angle

ECL questions in Dip IFRS range from conceptual (explain the three stages and when each applies) to calculation (calculate the ECL allowance for a portfolio using a provision matrix).

Most tested areas:

Stage migration scenarios: given information about a loan's credit quality at origination and at the reporting date, determine which stage applies and calculate the ECL. Know that 30 days past due triggers Stage 2 rebuttable presumption and 90 days triggers Stage 3 rebuttable presumption.

Simplified approach: know it is mandatory for trade receivables without a significant financing component. Know staging does not apply. Know the provision matrix is a permitted practical expedient.

Interest income recognition: Stage 1 and Stage 2 use gross carrying amount. Stage 3 uses net carrying amount. This distinction is consistently tested.

Write-off mechanics: know that write-off reduces both gross carrying amount and loss allowance with no P&L impact at the write-off date. Recovery after write-off is a gain.

FAQ

Does ECL apply to cash held at a bank?

Yes, technically. Cash and demand deposits are financial assets at amortised cost. However, the ECL on cash held at highly rated banks is typically immaterial and often considered negligible. The simplified approach or low credit risk exemption is usually applied.

Can a Stage 3 asset move back to Stage 2?

Yes. If the credit-impaired conditions are resolved and the asset no longer meets Stage 3 criteria, it can revert to Stage 2. The allowance reduces to lifetime ECL on the net basis, and interest income reverts to the gross basis.

Is the provision matrix mandatory for trade receivables?

No. It is a practical expedient. An entity can use any method to calculate lifetime ECL for trade receivables, provided it is consistent with IFRS 9's principles and incorporates forward-looking information.

What is the difference between expected credit loss and incurred loss?

Incurred loss (IAS 39) required objective evidence of a loss event before recognition. ECL requires recognition from day one based on probability-weighted expected losses, including forward-looking information.

Do ECL provisions affect regulatory capital for Indian banks?

Yes. RBI has issued guidance on how Ind AS 109 ECL provisions interact with Basel III capital requirements. The interaction between accounting provisions and regulatory capital deductions is complex and bank-specific.

How are ECL provisions for foreign currency receivables measured?

ECL is measured in the functional currency of the financial asset. Foreign exchange movements on the gross carrying amount are recognised separately in profit or loss as FX gains or losses. The ECL itself is calculated on the local currency equivalent.
