Executive summary (30 seconds):
If the company used the wrong contract terms, omitted a lease entirely or applied the accounting model incorrectly at inception, the issue usually points to an error. If the company received new information, changed assumptions or signed an amendment that genuinely altered the economics, the impact may be treated as a current-period change in estimate or modification.

When is it an error and when is it a change in estimate?

| Situation | Typical conclusion |
|---|---|
| Lease omitted from the register from day one | Likely prior-period error |
| Wrong discount rate used because contract facts were misunderstood | Likely prior-period error |
| New amendment changes lease term or payments | Usually current-period modification |
| Management updates assumptions based on new information | Usually change in estimate |
Where lease corrections hit the statements
A lease correction in IFRS consolidation rarely affects only one line. It can change depreciation, interest expense, liabilities, right-of-use assets, EBITDA and the note disclosures at the same time. That is why a narrow journal-entry view is dangerous.
- P&L — depreciation and finance cost may need to be recalculated.
- Balance sheet — right-of-use asset and lease liability move together; the IFRS 16 calculator helps frame the first calculation.
- EBITDA — management metrics may change materially, especially under IFRS 16 style reporting.
- Notes — maturity profile, lease commitments and policy wording may all need updating.
What documentation matters most
- full lease register with all contracts and amendments,
- clear memo explaining why the correction is needed,
- calculation showing old vs new treatment and the impact by statement line,
- updated note disclosure and accounting policy where relevant.
From my practice: Practical risk: the biggest problem is often not the recalculation itself, but the lack of documentation explaining whether the issue is an error, a reassessment or a modification. Without that distinction, both auditors and management lose time.
FAQ
Common questions
Does every lease correction need a prior-year restatement?▾
No. Restatement depends on whether the issue is a genuine prior-period error or a current-period change in estimate or lease modification.
Why do lease corrections affect EBITDA?▾
Because lease accounting often shifts part of the cost from operating expense into depreciation and finance cost, which changes how EBITDA is presented even when cash outflow is unchanged.
