When impairment testing is required
Impairment testing is required whenever there is an indication that an asset's carrying amount may exceed its recoverable amount. This is not an annual routine by default — it is triggered by indicators. However, in practice, most organisations review for indicators at least annually as part of their year-end financial reporting process.
- Significant physical damage or deterioration observed during verification
- Technological obsolescence making the asset less useful
- Market value decline beyond normal depreciation
- Asset taken out of active use or scheduled for early disposal
- Adverse changes in the regulatory or economic environment
- Performance significantly below expectations
Measuring the impairment loss
The impairment loss is the amount by which the carrying amount exceeds the recoverable amount. The recoverable amount is the higher of fair value less costs to sell, and value in use. For public sector entities under GRAP, this is adjusted to reflect service potential rather than future cash flows.
The role of condition data
This is where good asset management directly supports financial reporting. When the asset register contains current condition grades, maintenance history, and utilisation data, impairment assessments are evidence-based rather than estimate-based. Auditors respond much better to impairment conclusions that are backed by physical verification data and condition trends.
Documentation requirements
Every impairment assessment needs documented evidence of the indicator, the measurement method, the resulting adjustment, and the disclosure. The most common audit finding is not incorrect impairment — it is insufficient documentation supporting the impairment conclusion.
