How auditors test fixed asset additions, existence, depreciation, disposals, and impairment indicators.
Fixed assets are tested for existence, completeness, rights, capitalization, depreciation, disposals, and impairment. The auditor’s approach depends on the direction of risk. Overstatement risk often leads to inspecting recorded assets. Completeness risk leads to tracing capital expenditures and construction activity into the fixed asset register.
The AUD exam frequently tests whether the auditor can separate capital expenditures from repairs and maintenance, recalculate depreciation, and recognize impairment indicators. A fixed asset may physically exist but still be misstated if it is owned by another party, depreciated using unreasonable assumptions, or carried above recoverable value.

The direction of testing determines the assertion addressed.
| Audit objective | Procedure | Assertion |
|---|---|---|
| Recorded asset exists | Select items from the fixed asset register and physically inspect them | Existence |
| All additions are recorded | Trace vendor invoices, capital budgets, and board approvals to the fixed asset register | Completeness |
| Entity owns or controls the asset | Inspect title documents, purchase contracts, financing agreements, or lease contracts | Rights and obligations |
| Disposals are recorded | Inspect sale proceeds, retirement approvals, insurance claims, and removal from the asset register | Completeness of disposals |
| Repairs are not improperly capitalized | Inspect invoices and evaluate whether costs extend useful life or capacity | Classification |
Physical inspection is useful, but it is not enough. The auditor also considers title, location, condition, serial numbers, and whether the asset is still in use.
Capitalization testing focuses on whether the cost should be recorded as an asset or expensed. Costs that acquire, construct, or improve a long-lived asset may be capitalized. Routine maintenance that only keeps the asset in ordinary operating condition is usually expensed.
| Cost type | Audit concern |
|---|---|
| New asset purchase | Was the cost authorized and recorded in the correct asset class? |
| Major improvement | Did it extend useful life, capacity, or efficiency enough to capitalize? |
| Routine repair | Was it incorrectly capitalized to inflate income? |
| Construction in progress | Are accumulated costs valid, complete, and transferred when placed in service? |
| Interest capitalization | Was capitalization limited to qualifying assets and periods? |
The auditor reviews capitalization thresholds, approval policies, vendor invoices, project records, and account coding.
Depreciation testing evaluates useful life, residual value, depreciation method, placed-in-service date, and mathematical accuracy. Recalculation is common because depreciation is formula-driven.
| Depreciation input | Audit procedure |
|---|---|
| Historical cost | Agree to invoices, contracts, freight, installation, and capitalized project records |
| Placed-in-service date | Inspect receiving, installation, or readiness evidence |
| Useful life | Compare to policy, historical experience, industry data, and expected use |
| Residual value | Evaluate market support and disposal history |
| Method | Determine whether straight-line, units-of-production, or accelerated method matches use pattern |
| Accumulated depreciation | Recalculate and compare to the fixed asset register and general ledger |
Changes in useful life, residual value, or depreciation method may be changes in estimate or principle depending on the facts and the applicable framework. The auditor evaluates support and disclosure when material.
Long-lived assets are tested for impairment when events or changes in circumstances indicate the carrying amount may not be recoverable. Common impairment indicators include physical damage, obsolescence, declining demand, adverse legal changes, restructuring, or continuing losses associated with an asset group.
Disposal testing ensures retired or sold assets are removed from the records and gains or losses are recognized properly. The auditor inspects sale agreements, cash receipts, board approvals, insurance documents, and asset register removals.
| Indicator | Audit response |
|---|---|
| Asset no longer used | Inspect status, management plans, and recoverability analysis |
| Market demand declined | Review cash flow forecasts and external market evidence |
| Technology changed | Evaluate useful life and impairment assumptions |
| Asset sold | Agree proceeds, remove cost and accumulated depreciation, and recalculate gain or loss |
| Construction project abandoned | Evaluate write-off or impairment |
Do not treat physical existence as proof of valuation. An asset can exist and still be impaired or depreciated incorrectly.
Do not test completeness by starting only with the fixed asset register. Completeness requires tracing from source records or capital projects into the register.
Do not assume every repair can be capitalized. The auditor evaluates whether the cost creates future economic benefit beyond ordinary maintenance.
Do not ignore fully depreciated assets still in use. They may indicate useful-life estimates require review, though continued use is not automatically an error.
