Retrospective application
IAS 8 generally requires retrospective application of qualifying changes in accounting policy unless a standard’s transition provisions specify otherwise or the effects are impracticable to determine. Adjust opening balances and comparative amounts as required. Material prior-period errors are generally corrected by retrospective restatement, which is related but distinct. Changes in accounting estimates generally apply prospectively. Explain relevant disclosures and the reason for the change.
Worked example
A company changes a policy voluntarily because the new policy is more reliable and relevant. If applying it retrospectively reduces prior-year closing inventory by $10,000 and is practicable, it adjusts the comparative figures and relevant opening equity as required.
Common mistake
Restating prior years for an ordinary change in useful-life estimate, or assuming every new standard requires identical transition treatment regardless of its specific provisions.
