IFRS 9 ECL for trade receivables: the provision matrix explained
IFRS 9 requires every business with trade receivables to provide for expected credit losses (ECL): the losses it expects in future, not only the debts that have already gone bad. For most businesses, the practical way to do it is a provision matrix.
The simplified approach
Banks follow a three-stage model. Businesses with ordinary trade receivables do not have to. For trade receivables without a significant financing component, IFRS 9 requires the simplified approach: you always recognise lifetime expected credit losses, with no staging.
What a provision matrix is
A provision matrix is a table of loss rates by age of debt. You group your receivables by how overdue they are, apply an expected loss rate to each group, and add up the result. IFRS 9 allows it as a practical expedient, as long as the rates reflect your own loss history and are adjusted for current and forecast conditions.
How to build one
- Segment your customers where their credit risk differs, for example by region, product or customer type.
- Choose a history period long enough to be representative.
- Calculate historical loss rates for each ageing bucket, based on how much of the debt in that bucket was never collected.
- Adjust for the future. If conditions are getting worse or better than in your history, change the rates and record why.
- Apply the rates to the receivables balance at the reporting date.
- Document it so that your auditors can follow the data, the assumptions and the calculation.
An illustration
The figures below are invented to show the arithmetic. Your own rates must come from your own data.
| Age of debt | Balance | Loss rate | ECL |
|---|---|---|---|
| Not yet due | 500,000 | 1% | 5,000 |
| 1 to 30 days overdue | 200,000 | 3% | 6,000 |
| 31 to 60 days overdue | 100,000 | 6% | 6,000 |
| 61 to 90 days overdue | 50,000 | 15% | 7,500 |
| Over 90 days overdue | 30,000 | 40% | 12,000 |
| Total | 880,000 | 36,500 |
Common mistakes
- Using historical rates with no forward-looking adjustment.
- Treating all customers as one group when their risk clearly differs.
- Leaving out balances that are not yet due. They carry expected losses too.
- Building the matrix once and never updating it. It must be refreshed at each reporting date.
