In accounting and audit firms, there is a decision that never makes the headlines, yet it can turn a company’s results upside down. On the face of it, it is a simple decision: “we add a year to the asset’s useful life” or “we cut it by two years”. It may look like a technical figure in the depreciation schedule, but in reality it is a double-edged sword. Revising the useful life of a fixed asset is the back door through which some companies enter to flatter their profits, or the gateway through which prudent companies leave to face reality candidly.
So when is a company entitled to revise that life? What are the reasons that compel it to do so? And why are regulators and banks in Kuwait focusing on it more and more?
First: What is useful life, and why do we review it?
The useful life of an asset is, quite simply: “How many years do we expect to benefit from this asset before it becomes scrap?” Under International Accounting Standard IAS 16, this estimate is not carved in stone. Rather, it is an “accounting guess” that must be reviewed at the end of every financial year. The aim? That the financial statements reflect the true reality, not sell us an illusion built on old numbers.
Second: When is a revision required? (6 professional reasons)
Auditors do not accept a revision without strong justification. These are the most important reasons:
1. A change in the manner of use
Turning an administrative car into a field vehicle that operates 12 hours a day requires the useful life to be reduced immediately. And the reverse is true.
2. Major overhauls and major maintenance
Spending millions on a complete overhaul of a machine gives it back 5 additional years → the useful life is extended prospectively.
3. Technological obsolescence
A computer or telecommunications equipment becomes unusable because of new technologies, even if it is technically sound. This is very common in the banking and telecommunications sector in Kuwait.
4. Operational expansion or contraction
- Running a production line on three shifts → a shorter life.
- Converting a warehouse into an administrative office → a longer life.
5. Legal and contractual reasons
A 5-year lease requires the improvements to be depreciated over the lease term, even if their technical life is 20 years.
6. A change in the estimates of scrap value (Residual Value)
A rise in scrap prices or resale value reduces the depreciable amount.
Third: The hidden effect… the profit game
Revising the useful life is a “change in accounting estimate” under IAS 8, and it is applied prospectively only (no restatement of prior years).
A practical example:
An asset with a value of KD 10 million has been depreciated for 4 years (remaining carrying amount = KD 6 million).
- Remaining life of 4 years → annual depreciation expense = KD 1.5 million
- Extending the remaining life to 8 years → annual depreciation expense = KD 750,000 only
The result: an increase in operating profit of KD 750,000 a year without selling a single product. That is why the Capital Markets Authority and the banks scrutinise any material revision closely and ask for an independent technical report.
How do you protect yourself as an auditor or an investor?
- Ask for a technical report from an engineer or a specialist valuer.
- Compare depreciation rates with those of similar companies in the sector.
- Watch for repeated revisions at year-end.
- Focus on the effect on EBITDA and on real cash flows.
Conclusion
The useful life of an asset is not merely a number in an equation; it is a reflection of the asset’s story inside your company: how it is used, how it is maintained, and how the world around it changes. The golden rule: “Do not extend the life of the asset in order to extend the life of your illusory profits. Extend its life only when you have real technical and financial evidence.”
In the end, the smart investor does not only ask “How much is the profit?”, but asks: “How much of this profit came from a change in an accounting estimate?”
And there, in that question, lies the truth.
