Subsequent Measurement: Amortization vs Impairment
1. Intangible Assets with Finite Useful Lives
Amortization: Systematic allocation of depreciable amount over useful life.
- Amortization Method: Reflect pattern of consumption (usually straight-line)
- Useful Life: Period asset is expected to generate benefits
- Residual Value: Usually zero unless third party commitment to purchase
- Review: Review amortization period/method at each reporting date
2. Intangible Assets with Indefinite Useful Lives
No Amortization: Not amortized but tested for impairment annually.
- Indefinite Life: No foreseeable limit to period over which asset will generate cash flows
- Examples: Some trademarks, perpetual licenses
- Review: Review useful life assessment annually
Common Intangible Assets:
| Asset Type | Typical Life | Amortization | Impairment Test |
|---|---|---|---|
| Patents | Legal life (e.g., 20 years) | Yes | When indicators exist |
| Copyrights | Legal life + economic life | Yes | When indicators exist |
| Trademarks | Indefinite or finite | Depends on life | Annual if indefinite |
| Goodwill | Indefinite | No | Annual (mandatory) |
| Software | 3-5 years typically | Yes | When indicators exist |
