Impairment and obsolescence of a capitalized model

The posting

A capitalized model or training run that is superseded before the end of its useful life must be tested for impairment and written down when its carrying amount exceeds its recoverable amount IAS 38-97. AI obsolescence is fast, so impairment triggers, a newer model, a strategy change, disuse, should be monitored actively rather than discovered at year-end.

What triggers impairment

How the write-down is measured

Reduce the carrying amount to the recoverable amount and recognize the difference as an impairment loss in the period. This interacts with the useful-life estimate: frequent impairments are a signal the life was set too long in the first place.
