CECL

Definition

CECL replaced the incurred-loss approach for trade receivables, loans, held-to-maturity debt and similar assets. The allowance is the amount management expects not to collect over the life of the asset, estimated from historical loss experience adjusted for current conditions and reasonable and supportable forecasts. Private companies adopted it for years beginning after December 15, 2022.

Why it matters in an audit or review

The estimate is judgmental, so inherent risk is often elevated. AU-C 540 has the auditor test the method, data and assumptions and consider management bias. Many small entities use an aging-based loss rate approach, which the auditor must still show is appropriate.

Example

Illustrative: receivables of $2,000,000 are aged into buckets. Current $1,200,000 at 0.5% is $6,000. 1-30 days past due $400,000 at 2% is $8,000. 31-90 days $250,000 at 8% is $20,000. Over 90 days $150,000 at 10% is $15,000. The model allowance is 6,000 + 8,000 + 20,000 + 15,000 = $49,000. Management adds $10,000 for a forecast of weaker collections, for a total of $59,000.

Common mistakes

• Applying historical rates without any current or forecast adjustment.
• Using loss data that does not match the pooled receivables.
• Not documenting why the pools share risk characteristics.
