IFRS 9 explained: classification, impairment and expected credit loss
A working introduction to IFRS 9 covering financial asset classification, the three-stage impairment model and the simplified receivables approach.
What IFRS 9 covers
IFRS 9 Financial Instruments sets out how entities classify and measure financial assets and liabilities, how they recognize impairment and how hedge accounting works. For most non-financial companies the practical impact is concentrated in one place: expected credit losses on trade receivables.
Classification and measurement
Financial assets are classified using the business model for managing them and the contractual cash flow characteristics. The resulting categories are amortized cost, fair value through other comprehensive income, and fair value through profit or loss. Ordinary trade receivables held to collect contractual cash flows normally sit at amortized cost.
The expected credit loss model
IFRS 9 replaced an incurred-loss approach with a forward-looking expected credit loss model. Under the general model, exposures move through three stages:
- Stage 1: no significant increase in credit risk since initial recognition; twelve-month expected credit losses.
- Stage 2: significant increase in credit risk; lifetime expected credit losses.
- Stage 3: credit-impaired; lifetime losses with interest recognized on the net carrying amount.
Expected credit loss = Probability of default x Loss given default x Exposure at default
The simplified approach for receivables
For trade receivables and contract assets, entities commonly apply the simplified approach and recognize lifetime expected credit losses from the outset. A provision matrix based on ageing bands is the usual implementation: historical loss rates by band, adjusted for current conditions and reasonable forward-looking information. Rates typically rise sharply across current, 1-30, 31-60, 61-90 and 90-plus day bands.
Practical implementation points
Keep the customer ageing accurate, since the matrix depends entirely on it. Document the source of historical loss rates and the reasoning behind any forward-looking adjustment. Reassess when economic conditions, customer concentration or collection practice change, and disclose the policy and key judgements.
