Review an asset's remaining useful life before renewing its depreciation schedule

A depreciation schedule can keep running long after the assumptions behind it stop matching the equipment. Ask the operating owner whether expected use, maintenance, replacement plans or restrictions have changed. An automatic rollover should not become the company's evidence that last year's estimate still makes sense.

For IFRS reporting, IAS 16 requires useful life and residual value to be reviewed at least at each financial year-end. This guide addresses that financial-reporting review. Tax depreciation follows its own rules, so a tax schedule should not supply the answer merely because it is available.

Give the reviewer current usage measures, condition assessments, repair history and the approved replacement plan. Explain whether a shorter production run, a second shift or a lease expiry changes how long the business expects to use the asset. Expected use by this business can differ from the period another buyer could keep the equipment operating.

Review assets in sensible groups, but identify exceptions. A fleet purchased together may now include units working different shifts or operating in different conditions. Preserve the reason for a common estimate and the evidence behind any unit that needs separate treatment. Avoid extending every life just because one machine outperformed the original plan.

Retain the condition, age and disposal-cost assumptions used in estimating residual value. A dealer's offer for today's nearly new asset may not describe the condition expected at the end of its useful life. Ask the accountant to assess comparable evidence under the standard's definition instead of substituting the investment team's future sale forecast.

Record where an estimate is unsupported or the resale market has changed. Useful-life and residual-value judgments are related, but they answer different questions. Keep their approvals separate enough that a reviewer can see whether a change in annual depreciation came from longer use, a different residual amount or both.

As a simplified illustration, an asset has a $60,000 carrying amount and an approved $6,000 residual value. If its reassessed remaining life is three years and straight-line depreciation remains appropriate, the remaining depreciable amount is $54,000, or $18,000 a year. This illustrates arithmetic after approval; it does not establish an appropriate life or residual value for another asset.

Have the accountant determine whether the facts represent a change in estimate or expose an earlier error, and specify the effective period. Keep the old schedule, the revised calculation and the posted adjustment connected. Verify any partial-period treatment in the software rather than assuming the annual illustration matches the first journal.

Save the reviewed population, exceptions, operating evidence and conclusion with the asset register. A documented decision to retain an estimate is useful when supported by current facts. Name the events that should trigger another review before the next annual cycle, such as unexpected damage, a site closure or a confirmed replacement date.
