IFRS 9 Expected Credit Loss Model: Three Stages Explained

Updated 11 October 2026 · Fact-checked

The IFRS 9 expected credit loss model recognises impairment losses before a default happens. Stage 1 books 12-month ECL, stage 2 books lifetime ECL after a significant rise in credit risk, and stage 3 books lifetime ECL on credit-impaired assets. Trade receivables normally use a simplified lifetime ECL, often via a provision matrix.

Understand Impairment of Financial Assets: Expected Credit Loss Model

Under the old incurred loss model (IAS 39), you booked a loss only when there was objective evidence that a loss event had happened. Losses were recognised late. IFRS 9 replaced this with the expected credit loss (ECL) model. You now provide for losses from the day you recognise the asset, based on what you expect, not on what has already gone wrong.

ECL is the probability-weighted estimate of credit losses, discounted at the asset's effective interest rate (EIR). A credit loss is the difference between the cash flows due under the contract and the cash flows you expect to receive. The estimate must be unbiased and must use reasonable and supportable information available without undue cost, including forward-looking information.

The general approach has three stages. Stage 1: credit risk has not increased significantly since initial recognition. You recognise 12-month ECL (losses from defaults possible in the next 12 months) and interest income on the gross carrying amount. Stage 2: credit risk has increased significantly. You recognise lifetime ECL, and interest is still on the gross carrying amount. Stage 3: the asset is credit-impaired. You recognise lifetime ECL, and interest income is now on the net carrying amount (gross less allowance).

The simplified approach removes the staging. For trade receivables and contract assets (IFRS 15) that have no significant financing component, you must always recognise lifetime ECL. For those with a significant financing component, and for lease receivables, you may choose the simplified approach as a policy. Most entities use a provision matrix: group receivables by days past due and apply a loss rate to each group, adjusted for forward-looking information.

The model applies to debt instruments at amortised cost, debt instruments at FVOCI, lease receivables, contract assets, loan commitments and financial guarantee contracts. It does not apply to equity investments. For FVOCI debt assets, the allowance goes through OCI and does not reduce the carrying amount, which stays at fair value. Impairment losses and reversals go to profit or loss.

Key rules to remember

ECL (single scenario): ECL = PD × LGD × EAD, discounted at the EIR; PD is probability of default, LGD is loss given default, EAD is exposure at default. In exams you are usually given the loss or the rate directly.
Probability-weighted ECL: ECL = Σ (probability of scenario × present value of cash shortfall in that scenario); Use when the question gives several scenarios. Probabilities must add to 100%.
Stage 1 allowance: 12-month ECL; Applies when there has been no significant increase in credit risk since initial recognition.
Stage 2 and 3 allowance: Lifetime ECL; Applies after a significant increase in credit risk (stage 2) or when credit-impaired (stage 3).
Interest income, stages 1 and 2: Gross carrying amount × EIR; The allowance does not reduce the interest base.
Interest income, stage 3: (Gross carrying amount − loss allowance) × EIR; Net carrying amount is used from the period after the asset becomes credit-impaired.
Provision matrix (simplified approach): Allowance = Σ (receivables in age band × loss rate for that band); Loss rates come from historical experience, adjusted for current conditions and forecasts.
Charge to profit or loss: Closing allowance − opening allowance; An increase is an impairment loss. A decrease is an impairment gain. Write-offs reduce both gross amount and allowance.
Rebuttable presumptions: More than 30 days past due = significant increase in credit risk; more than 90 days past due = default; These are presumptions, not fixed rules. An entity can rebut them with reasonable and supportable information.

How to solve Impairment of Financial Assets: Expected Credit Loss Model questions

Use this method for any ECL question, whether it is a loan, a bond, or a ledger of receivables.

1Identify the asset and its measurement category. Check ECL applies: amortised cost, FVOCI debt, lease receivable, contract asset or trade receivable. Equity investments are out of scope.
2Decide the approach. Trade receivables and contract assets without a significant financing component use the simplified approach. Other assets use the three-stage general approach.
3For the general approach, assign the stage at each reporting date. Look for evidence of a significant increase in credit risk (for example payments over 30 days late, downgrade, covenant breach) or credit impairment (for example default, bankruptcy, concession because of financial difficulty).
4Measure the allowance: 12-month ECL for stage 1, lifetime ECL for stages 2 and 3, or the provision matrix total for the simplified approach. Use the numbers given and discount only if the question asks.
5Calculate the charge: closing allowance less opening allowance. Post it to profit or loss as an impairment loss or gain.
6Calculate interest income. Use the gross carrying amount for stages 1 and 2, and the net carrying amount for stage 3.
7Present the result: carrying amount in the statement of financial position (gross less allowance, except FVOCI), and the profit or loss effect. Note disclosure points if asked.
8If the requirement asks for discussion, link the answer to the scenario and explain why the model is more timely than incurred loss, or why judgement and bias are an issue.

Quickest way: Three-question ECL check

When to use it: Use this when time is short and the question gives you the ECL figures and asks for the accounting entries and interest.

Ask 1: Is it trade receivables? If yes, write down the provision matrix total as the closing allowance, then go straight to the change in allowance.
Ask 2: If not, which stage is it in at each year end? Write the stage next to each date before you calculate anything.
Ask 3: Gross or net for interest? Stages 1 and 2 use gross. Stage 3 uses gross less allowance, and only from the period after it becomes credit-impaired.
Write the entry in one line: Dr Impairment loss (P&L), Cr Loss allowance, for the movement only.
State the closing carrying amount: gross less allowance. Then add one sentence tying the stage to the scenario facts.

Common mistakes in Impairment of Financial Assets: Expected Credit Loss Model

Waiting for an actual default before booking any provision.
Students carry over the old incurred loss thinking from IAS 39.
Fix: Under IFRS 9 every asset in scope carries at least 12-month ECL from initial recognition, unless it is a simplified-approach asset, which carries lifetime ECL from day one.
Charging the whole closing allowance to profit or loss each year.
Students forget the allowance is a cumulative balance.
Fix: Charge only the movement: closing allowance less opening allowance. Remember write-offs reduce the allowance before the year-end top-up.
Calculating stage 3 interest on the gross amount, or stage 2 interest on the net amount.
Students mix up the stage rules for interest.
Fix: Remember: gross for stages 1 and 2, net for stage 3. The switch to net happens once the asset is credit-impaired, not before.
Using the staged approach for ordinary trade receivables.
Students learn the three stages first and apply them everywhere.
Fix: Trade receivables without a significant financing component use lifetime ECL with no staging. Look for a provision matrix or ageing analysis in the question.
Treating 30 and 90 days past due as automatic, unrebuttable triggers.
Rules of thumb are remembered as hard rules.
Fix: They are rebuttable presumptions. Say that an entity can rebut them with reasonable and supportable evidence, but the scenario will usually tell you to follow them.
Reducing the carrying amount of an FVOCI debt instrument by the allowance.
Students apply the amortised cost treatment to all debt instruments.
Fix: For FVOCI the asset stays at fair value. The ECL charge goes to profit or loss and the matching credit goes to OCI, not to the asset.

Worked examples

Example 1

At 31 December 20X1 Daro Co has trade receivables of $1,000,000 with no significant financing component. It uses a provision matrix: not overdue $600,000 at 0.5%; 1 to 30 days overdue $250,000 at 2%; 31 to 60 days overdue $100,000 at 8%; over 60 days overdue $50,000 at 30%. The opening loss allowance was $22,000. Calculate the closing allowance, the charge to profit or loss and the net carrying amount of receivables.

Show the solution

Receivables are trade receivables without a significant financing component, so use the simplified approach: lifetime ECL through the provision matrix.
Not overdue: $600,000 × 0.5% = $3,000.
1 to 30 days: $250,000 × 2% = $5,000.
31 to 60 days: $100,000 × 8% = $8,000.
Over 60 days: $50,000 × 30% = $15,000.
Closing allowance = 3,000 + 5,000 + 8,000 + 15,000 = $31,000.
Charge to profit or loss = 31,000 − 22,000 = $9,000. Entry: Dr Impairment loss $9,000, Cr Loss allowance $9,000.
Net carrying amount = 1,000,000 − 31,000 = $969,000.

Answer: Closing allowance $31,000; charge to profit or loss $9,000; net receivables $969,000.

Example 2

On 1 January 20X1 Kell Co buys a $2,000,000 five-year bond at par, classified at amortised cost. The coupon is 5% paid annually in arrears and the EIR is 5%. Credit position: at 31 December 20X1 stage 1, 12-month ECL $10,000. At 31 December 20X2 stage 2, lifetime ECL $60,000. At 31 December 20X3 stage 3 (credit-impaired), lifetime ECL $400,000. Calculate interest income for 20X1 to 20X3, the impairment charge each year and the carrying amount at each year end. Then give interest income for 20X4, assuming the allowance stays at $400,000 and the asset stays in stage 3.

Show the solution

Assume the bond was not credit-impaired on purchase, so the general approach applies from stage 1. Gross carrying amount stays at $2,000,000 because EIR equals the coupon.
20X1 (stage 1): interest income = 2,000,000 × 5% = $100,000. Impairment charge = $10,000 (opening nil). Carrying amount = 2,000,000 − 10,000 = $1,990,000.
20X2 (stage 2): interest is still on gross = $100,000. Charge = 60,000 − 10,000 = $50,000. Carrying amount = 2,000,000 − 60,000 = $1,940,000.
20X3: the asset only becomes credit-impaired at the year end, so interest for the year is still on gross = $100,000. Charge = 400,000 − 60,000 = $340,000. Carrying amount = 2,000,000 − 400,000 = $1,600,000.
20X4 (stage 3): interest is on the net carrying amount = 1,600,000 × 5% = $80,000.

Answer: Interest income: 20X1 $100,000; 20X2 $100,000; 20X3 $100,000; 20X4 $80,000. Impairment charges: $10,000; $50,000; $340,000. Carrying amounts: $1,990,000; $1,940,000; $1,600,000.

Exam tips

Always name the approach first. Writing 'simplified approach, lifetime ECL' for receivables, or the stage for a loan, shows the marker you know which rule applies and earns method marks.
Show the movement in the allowance as a separate line. Markers give credit for the correct charge even if the closing allowance is slightly wrong.
In discussion parts, use the scenario facts: days past due, rating downgrades, industry conditions or forecast data. Then explain the stage consequence. This also supports the professional skills marks.
Be ready to contrast the models: IAS 39 recognised losses only after a loss event, so provisions came late and were criticised after the financial crisis. ECL is forward-looking but depends on judgement and estimates, which creates risk of bias or earnings management.
Watch for the wording on scope. Equity instruments, and assets at fair value through profit or loss, have no ECL allowance. FVOCI debt instruments do, but the allowance sits in OCI.

Impairment of Financial Assets: Expected Credit Loss Model: frequently asked questions

What are the three stages of the IFRS 9 ECL model?

Stage 1 is performing assets with no significant increase in credit risk: 12-month ECL and interest on the gross amount. Stage 2 has a significant increase in credit risk: lifetime ECL and interest on the gross amount. Stage 3 is credit-impaired: lifetime ECL and interest on the net amount.

How do you calculate ECL for trade receivables under the simplified approach?

You recognise lifetime ECL from day one, with no staging. Group receivables by age or risk, apply a loss rate to each group and add the results. The loss rates are based on past experience adjusted for current conditions and forecasts.

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

The incurred loss model (IAS 39) waited for objective evidence of a loss event before recognising impairment. The ECL model (IFRS 9) recognises expected losses from initial recognition and updates them using forward-looking information. This means losses are recognised earlier.

Why is interest calculated on the net amount in stage 3?

Once an asset is credit-impaired, part of the contractual cash flows is not expected to be received. Applying the EIR to the amount net of the allowance avoids recognising interest income that is unlikely to be collected.

Does ECL apply to equity investments?

No. IFRS 9 impairment applies to debt instruments at amortised cost or FVOCI, lease receivables, contract assets, loan commitments and financial guarantee contracts. Equity investments are measured at fair value, so no ECL allowance is needed.
