ISA 540 (Revised) — Auditing Accounting Estimates and Related Disclosures
ISA 540 (Revised) is an international pronouncement addressing the audit of accounting estimates and related disclosures, including estimation uncertainty and management bias. It addresses the auditor’s responsibilities for accounting estimates and related disclosures. The auditor considers the method, significant assumptions, data, estimation uncertainty and possible management bias, adapting the work to the assessed risks and circumstances.
Worked example
The auditor challenges assumptions and tests data used to estimate a warranty provision.
Common mistake
Do not accept an accounting estimate merely because it is numerically precise or supported by management’s calculation.
