Banks and companies lend money and sell on credit, and some borrowers do not pay. The old rule waited until a loss had actually happened before recording it. By then, the damage was done and the lender’s profits had been overstated for years. International Financial Reporting Standard (IFRS) 9 changed this. It asks the lender to look ahead.
From the day a loan or a receivable is recorded, the lender sets aside an allowance for the credit losses it expects, and increases it as the borrower’s position worsens.
This topic covers the expected credit loss model: what it applies to, the definitions, the three stages, how a significant increase in credit risk is assessed, how the loss is measured, the simplified approach, assets bought or originated already credit-impaired, undrawn commitments, presentation and disclosure. The previous topic covered classification and measurement. The next topic covers hedge accounting.
In 30 seconds
The expected credit loss model applies to financial assets at amortised cost, debt assets at fair value through other comprehensive income, lease receivables, contract assets, loan commitments and financial guarantees. A loss allowance is recognised from day one in three stages. Stage 1: no significant increase in credit risk since the start. Allowance = 12-month expected credit loss. Interest on the gross carrying amount.
Stage 2: significant increase in credit risk. Allowance = lifetime expected credit loss. Interest on the gross amount. Stage 3: credit-impaired. Allowance = lifetime expected credit loss. Interest on the net amount. The loss is probability-weighted, discounted at the effective interest rate and uses reasonable and supportable forward-looking information.
Trade receivables and contract assets without a significant financing component use the simplified approach: lifetime expected credit loss from the start, often with a provision matrix. Changes in the allowance go to profit or loss.

CAMA 2020 and impairment of financial assets
The Companies and Allied Matters Act 2020 (CAMA 2020) requires statements that follow IFRS and give a true and fair view.
| Section | What it says | Link to impairment |
|---|---|---|
| s. 377(1) and s. 378 | Directors prepare statements that follow IFRS and give a true and fair view | Allowances for credit losses follow IFRS 9 |
| s. 374(1) | The company keeps accounting records | Ageing data, default history and the model inputs are kept |
| s. 385 | The directors’ report covers performance, risk management and compliance | Credit risk and its management may need comment |
| s. 404(7) | The audit committee reviews policies and internal control | It can review the model, the staging rules and the forward-looking assumptions |
What the model applies to
- financial assets at amortised cost;
- debt assets at fair value through other comprehensive income (not equity);
- lease receivables (IFRS 16) and contract assets (IFRS 15);
- loan commitments not at fair value through profit or loss; and
- financial guarantee contracts within IFRS 9.
Equity investments and assets at fair value through profit or loss are not tested. Their fair value already shows any loss.
The three-stage general approach
| Stage | Credit risk | Loss allowance | Interest income on |
|---|---|---|---|
| 1 | No significant increase since initial recognition (or low credit risk) | 12-month expected credit loss | Gross carrying amount |
| 2 | Significant increase since initial recognition, not credit-impaired | Lifetime expected credit loss | Gross carrying amount |
| 3 | Credit-impaired | Lifetime expected credit loss | Net carrying amount (gross less allowance) |
On day one an allowance equal to 12-month expected credit loss is recognised. At each reporting date the entity reassesses the stage. If credit risk improves, the asset moves back to Stage 1.
Significant increase in credit risk
Compare the risk of default over the expected life at the reporting date with the risk at initial recognition, using reasonable and supportable information available without undue cost or effort (past events, current conditions and forecasts). The assessment is relative, not an absolute rating level.
There are two rebuttable presumptions: credit risk has increased significantly if payments are more than 30 days past due, and default is presumed to occur no later than when payments are 90 days past due (a backstop). An instrument with low credit risk at the reporting date (for example investment grade) may be assumed not to have increased significantly.
Credit-impaired
Evidence includes significant financial difficulty of the borrower, a breach of contract such as default or being past due, a concession granted because of the borrower’s difficulty, probable bankruptcy, the disappearance of an active market because of financial difficulty, and purchase at a deep discount that reflects incurred credit losses.
Measuring expected credit loss
The measure must be:
- unbiased and probability-weighted, from a range of outcomes (not the best or worst case);
- discounted at the original effective interest rate (or credit-adjusted rate for purchased or originated credit-impaired assets); and
- based on reasonable and supportable information, including forecasts of future conditions.
A credit loss can arise even if the entity expects to be paid in full, if payment is expected later than the contract requires, because of the time value of money. Collateral and credit enhancements that are part of the contract and enforceable are taken into account. For a simple exposure:
Expected credit loss = probability of default × loss given default × exposure at default, discounted.
The simplified approach
For trade receivables and contract assets that have no significant financing component, the entity must recognise lifetime expected credit loss from the start. There is no need to track the stages. For trade receivables and contract assets with a significant financing component, and for lease receivables, the entity chooses this approach as a policy.
A provision matrix applies loss rates, based on history and adjusted for current and forward-looking information, to ageing buckets.
Purchased or originated credit-impaired assets
These have a credit-adjusted effective interest rate that already includes the expected credit losses in the expected cash flows. There is no day-one allowance. Afterwards only the cumulative changes in lifetime expected credit loss since initial recognition are recognised as an allowance. A favourable change is an impairment gain.
Undrawn commitments, presentation and write-off
- Loan commitments follow the same stages. Stage 1 uses the 12-month expected loss on the part expected to be drawn. Stage 2 uses lifetime expected loss. The loss on a commitment is shown as a provision.
- The allowance for an asset at amortised cost is a contra-asset that reduces the gross carrying amount. For a debt asset at fair value through other comprehensive income (FVOCI) the carrying amount stays at fair value. The impairment expense goes to profit or loss and the allowance is accumulated in other comprehensive income.
- Write-off: the gross carrying amount and the allowance are reduced when there is no reasonable expectation of recovering the asset. A write-off is a derecognition event.
- Movements in the allowance are recognised in profit or loss as an impairment loss or gain.
Disclosure
IFRS 7 requires a reconciliation of the opening to the closing loss allowance by class, an explanation of the inputs, assumptions and estimation techniques, the definitions of default and write-off, credit risk management practices, and information on collateral and credit enhancements.
The rules in more depth
Why the model is forward-looking
Waiting for a loss meant that losses appeared late, in a crisis, when it was too late to build reserves. The model recognises a loss earlier and in line with the credit risk the lender is bearing.
Why interest changes to the net basis in Stage 3
For an asset that is already credit-impaired, interest on the gross amount would include income that the lender does not expect to collect.
Why the effective rate ignores expected losses
The effective rate comes from contractual cash flows. Expected losses are recorded in the allowance. Doing both would count them twice.
Judgement and ethics
The model needs judgement: the staging threshold, probabilities and forecasts. An entity could delay moving assets to Stage 2 or adjust forecasts to lift profit. Accountants must apply the assumptions faithfully and document them.
Effect on analysis
Loss allowances can be large for banks. Analysts check the proportion in Stage 2 and 3, the coverage ratio (allowance divided by gross exposure) and the movement in the charge.
Worked examples
Example 1: 12-month and lifetime expected credit loss. A 3-year bullet loan of ₦1,000,000 at an effective rate of 8%. Marginal probabilities of default are 2% in year 1, 3% in year 2 and 4% in year 3. The loss given default is 40% and the exposure is ₦1,000,000 throughout. Discount factors at 8%: 0.9259, 0.8573, 0.7938.
- Stage 1 (12-month):
₦1,000,000 × 40% × 2% × 0.9259 = ₦7,407. - Stage 2 (lifetime):
₦400,000 × (0.02 × 0.9259 + 0.03 × 0.8573 + 0.04 × 0.7938) = ₦400,000 × 0.07599 = ₦30,396. - If the loan moves from Stage 1 to Stage 2, the allowance rises by ₦22,989. Dr impairment loss (profit or loss) ₦22,989; Cr loss allowance ₦22,989. Interest stays on the gross amount.
Example 2: simplified approach. A provision matrix for trade receivables.
| Ageing | Gross (₦) | Loss rate | Expected credit loss (₦) |
|---|---|---|---|
| 0 to 30 days | 500,000 | 0.5% | 2,500 |
| 31 to 60 days | 100,000 | 2.0% | 2,000 |
| 61 to 90 days | 50,000 | 6.0% | 3,000 |
| Over 90 days | 20,000 | 20.0% | 4,000 |
| Total | 670,000 | 11,500 |
Dr impairment expense ₦11,500; Cr loss allowance ₦11,500 (adjusted for any opening allowance).
Example 3: loss allowance on a bond over its life. A ₦48m bond at amortised cost is bought for 3 years. Management estimates the loss allowance at ₦1.00m on day one, ₦1.50m at the end of year 1, ₦1.20m at the end of year 2 and nil at redemption. The bond is redeemed in full.
| Date | Allowance (₦m) | Movement | Profit or loss |
|---|---|---|---|
| Day one | 1.00 | +1.00 | Loss 1.00 |
| End of year 1 | 1.50 | +0.50 | Loss 0.50 |
| End of year 2 | 1.20 | −0.30 | Gain 0.30 |
| Redemption | nil | −1.20 | Gain 1.20 |
Net effect on profit or loss over the life = 1.00 + 0.50 − 0.30 − 1.20 = nil, because no loss occurred. Interest income each year is on the gross amount, and the allowance does not change the effective rate.
Note: ICAN’s journal summary for this bond labels the year 1 increase as an impairment gain and the later releases as impairment losses. An increase in the allowance is always a loss and a decrease is a gain, so ours is slightly different from ICAN’s. In the exam, label the direction clearly.
Example 4: a credit-impaired bond. Company X holds a bond of ₦1m that pays 5% for two years and then 7% for two years, redeemed at par after four years. The effective rate is 5.942%. At the end of year 2 the amortised cost is ₦1,019,407. The issuer is in financial difficulty and X expects to receive only 60% of the remaining cash flows. There is already a loss allowance of ₦100,000.
- Expected cash flows.
year 3 ₦70,000 × 60% = ₦42,000.
Year 4 ₦1,070,000 × 60% = ₦642,000. - Present value at 5.942%: ₦42,000 × 0.9439 + ₦642,000 × 0.8910 = ₦39,644 + ₦572,022 = ₦611,666.
- Required allowance.
₦1,019,407 − ₦611,666 = ₦407,741.
Additional charge = ₦407,741 − ₦100,000 = ₦307,741. - Dr impairment loss (profit or loss) ₦307,741; Cr loss allowance ₦307,741.
- The asset is now Stage 3.
Interest in year 3 = net carrying amount ₦611,666 × 5.942% = ₦36,345.
Note: ICAN’s journal for this example writes the financial asset down directly by ₦407,741. The lender still expects to recover 60%, so there is a reasonable expectation of recovery and the asset is not written off. The loss is recorded by increasing the loss allowance, so ours is slightly different. In the exam, use an allowance unless the question says the asset is written off.
Example 5: debt asset at fair value through other comprehensive income. A bond is carried at a fair value of ₦50,000,000. A 12-month expected credit loss of ₦200,000 is estimated.
- Dr impairment loss (profit or loss) ₦200,000; Cr other comprehensive income (loss allowance) ₦200,000.
- The carrying amount stays at the fair value of ₦50,000,000. No allowance is shown against the asset.
How to score full marks
- Name the approach: general (three stages) or simplified.
- State the stage and quote the evidence (change in probability of default, days past due, rating, forecasts).
- Compute the loss as probability × loss given default × exposure, discounted at the original effective rate, and show the workings.
- Say where the entry goes: profit or loss for the charge, contra-asset for amortised cost, other comprehensive income for the FVOCI allowance.
- Get the interest basis right: gross for Stages 1 and 2, net for Stage 3.
- Use the right direction: an increase in the allowance is a loss.
- Link to disclosure (reconciliation, inputs, definitions).
Common mistakes in the exam
- Waiting for a loss event before recognising any allowance.

Model answers
Show the model answer to Question 11
(a) Scope and stages (5 marks). The model applies to assets at amortised cost, debt assets at fair value through other comprehensive income, lease receivables, contract assets, loan commitments and financial guarantees. (1.5) Stage 1 is no significant increase in credit risk: 12-month expected loss, interest on gross. (1.25) Stage 2 is a significant increase: lifetime expected loss, interest on gross. (1.25) Stage 3 is credit-impaired: lifetime expected loss, interest on net. (1)
(b) Simplified approach (5 marks).
- For trade receivables and contract assets without a significant financing component, lifetime expected loss is recognised from the start with no staging, usually using a provision matrix. (2)
- Allowance = 800,000 × 1% + 200,000 × 3% + 100,000 × 10% + 50,000 × 40% = 8,000 + 6,000 + 10,000 + 20,000 = ₦44,000. (3)
Show the model answer to Question 12
(a) Expected credit loss (6 marks).
- 12-month = ₦2,000,000 × 50% × 1% × 0.9091 = ₦9,091. (2.5)
- Lifetime = ₦1,000,000 × (0.01 × 0.9091 + 0.02 × 0.8264 + 0.03 × 0.7513) = ₦1,000,000 × 0.048158 = ₦48,158. (3.5)
(b) Assessment and interest (4 marks). Compare the risk of default over the expected life at the reporting date with that at initial recognition using reasonable and supportable forward-looking information. (1.5) Rebuttable presumption at 30 days past due, and a low credit risk exemption. (0.5) Interest is on the gross carrying amount in Stages 1 and 2 and on the net carrying amount in Stage 3. (2)
(c) Credit-impaired asset (6 marks).
- Required allowance.
₦2,000,000 − ₦1,200,000 = ₦800,000. (2) - Additional charge.
₦800,000 − ₦150,000 = ₦650,000, Dr impairment loss, Cr loss allowance. (2) - Next year’s interest.
net carrying amount ₦1,200,000 × 8% = ₦96,000. (2)
(d) Treatment (4 marks). For a debt asset at FVOCI the carrying amount stays at fair value. The expense is in profit or loss and the allowance is accumulated in other comprehensive income. (2) A purchased or originated credit-impaired asset has a credit-adjusted effective rate and no day-one allowance, and only cumulative changes in lifetime expected loss are recognised, with favourable changes as gains. (2)
Show the model answer to Question 13
(a) Indicators (4 marks). Any four: significant financial difficulty of the borrower, breach of contract such as default or past due status, a concession granted because of the borrower’s difficulty, probable bankruptcy, the disappearance of an active market because of financial difficulty, a deterioration in the probability of default or credit rating, or more than 30 days past due. (1 each)
(b) Profit or loss (4 marks). Year 1 loss ₦20,000. Year 2 loss ₦15,000 (35,000 − 20,000). Year 3 gain ₦23,000 (35,000 − 12,000). Year 4 gain ₦12,000. (1 each) The net effect is nil, because the loan was repaid in full.
(c) Write-off (2 marks). The gross carrying amount and the allowance are reduced when there is no reasonable expectation of recovering the asset. (1) It is a derecognition event. (1)
