Fixed asset valuation affects depreciation, profit, asset values and key ratios. A sound process begins with the correct recognition and cost of each asset, then applies a consistent subsequent-measurement policy and a separate impairment review when indicators arise.
This guide explains the cost and revaluation models, fair value evidence, depreciation after valuation, impairment testing and the controls needed to reconcile the fixed asset register with the financial statements.
What fixed asset valuation is designed to achieve
Fixed asset valuation determines the amount at which property, plant and equipment is reported after recognition. The objective is not to guess a selling price. It is to apply a consistent measurement policy that reflects the asset’s cost or revalued amount, accumulated depreciation and any impairment. The resulting carrying amount supports depreciation, performance analysis, borrowing decisions and reliable disclosures.
Valuation should be performed by asset class and supported by records that connect the physical asset, the fixed asset register and the general ledger. Land, buildings, machinery, vehicles and office equipment often have different useful lives, valuation evidence and impairment risks, so one blanket percentage is rarely appropriate.
Initial measurement at cost
An item that meets the recognition criteria is initially measured at cost. Cost normally includes the purchase price after discounts, non-refundable taxes, directly attributable costs of bringing the asset to the location and condition required for use, and an initial estimate of qualifying dismantling or restoration obligations. General administration, abnormal waste, training and start-up losses are normally excluded unless another Standard requires otherwise.
Judgement is needed when one project contains several components. A major inspection, roof, engine or production line component may need separate recognition and depreciation when its useful life differs from the remainder. Replaced components are derecognised so that the carrying amount does not contain both the old and new item.
Cost model and revaluation model
After recognition, an entity applies either the cost model or the revaluation model to an entire class of property, plant and equipment. Under the cost model, carrying amount equals cost less accumulated depreciation and accumulated impairment losses. Under the revaluation model, the asset is carried at a revalued amount based on fair value at the revaluation date, less later depreciation and impairment.
Revaluations must be sufficiently regular to keep carrying amounts from differing materially from fair value. Selecting only assets that increased in value is not acceptable. The policy applies to the whole class, although valuations may be completed on a rolling basis when the exercise is completed within a short period and values remain current.
Fair value evidence and valuation methods
Observable market evidence is strongest when comparable assets trade in an active market. Specialised buildings and machinery may require a valuation technique such as depreciated replacement cost, an income approach or another method consistent with the asset’s characteristics and available data. Assumptions should be documented, internally challenged and reconciled to the asset register.
Management should distinguish a valuation for financial reporting from an insurance value, tax value, forced-sale value or lender’s security value. Those amounts may use different assumptions and may not satisfy the reporting objective. Where an external valuer is used, management remains responsible for the accounting policy, completeness of the population and the reasonableness of inputs.
Depreciation after valuation
Depreciation begins when an asset is available for use and allocates the depreciable amount over the useful life. A revaluation changes the depreciable base and therefore affects future depreciation. Residual values, useful lives and depreciation methods should be reviewed at least at each year end, with changes generally treated prospectively as changes in estimates.
Land and buildings should be separated because land often has an indefinite useful life while buildings are depreciated. Significant components are depreciated separately. If an asset is idle but still available for use, depreciation normally continues unless it is fully depreciated or classified under another applicable standard.
Impairment and recoverable amount
Valuation under IAS 16 does not replace the impairment review under IAS 36. When indicators exist, the entity compares carrying amount with recoverable amount, which is the higher of value in use and fair value less costs of disposal. An impairment loss is recognised when carrying amount exceeds recoverable amount.
Indicators may include physical damage, technological obsolescence, adverse market changes, weaker performance or a plan to discontinue an operation. The test may need to be performed for a cash-generating unit when the individual asset does not produce largely independent cash inflows. Reversals are considered when estimates improve, subject to the applicable limits.
Worked carrying amount example
Assume equipment cost 120,000, has a 20,000 residual value and a five-year straight-line life. Annual depreciation is 20,000. After two years, carrying amount before impairment is 80,000. If recoverable amount is 68,000, an impairment loss of 12,000 is recognised. Future depreciation is based on the revised carrying amount, adjusted for residual value and remaining useful life.
If the entity instead applies a qualifying revaluation and fair value becomes 95,000, the accounting effect depends on previous revaluation movements and impairment losses. The revaluation surplus is not ordinary operating profit. Detailed entries and presentation should follow the applicable standard and the entity’s prior history for that asset.
Controls that make valuations auditable
A reliable valuation process starts with a complete asset population, unique asset IDs, ownership evidence, location records, acquisition dates and component details. Physical verification identifies missing, idle or damaged assets. Reconciliations explain movements from opening to closing carrying amount, including additions, disposals, transfers, depreciation, impairment and revaluation.
Review controls should address valuation credentials, model selection, comparable data, discount rates, useful lives, residual values and management bias. Approval should be independent of the person preparing the calculation. Supporting reports, photographs, invoices and calculations should be retained for audit and future revaluation cycles.
Practical review checklist
- Confirm the asset exists, is owned or controlled, and is available for use.
- Separate significant components with different useful lives.
- Include only costs that qualify for capitalisation.
- Apply one subsequent-measurement policy to the entire asset class.
- Document valuation methods, assumptions and evidence.
- Recalculate depreciation after revaluation or impairment.
- Reconcile the asset register to the general ledger.
- Review disclosures, approvals and audit evidence before reporting.
