Impairment occurs when an asset's carrying amount exceeds the amount expected to be recovered through use or sale.
Impairment is the accounting condition that exists when an asset’s carrying amount is greater than the amount expected to be recovered from using or selling it.
When impairment exists, the asset is overstated on the books and must usually be reduced through an Impairment Loss or related Write-Down.
The central comparison is:
If that condition holds, the asset is impaired.
Common indicators include:
Goodwill and other long-lived assets are common impairment subjects.
Impairment protects financial reporting from overstating asset values. It forces management to recognize that the recorded balance can no longer be justified by expected economic benefit.
That is why impairment sits at the intersection of valuation, prudence, and earnings quality.
Depreciation is systematic and expected. Impairment is a separate downward reassessment when value falls faster or farther than the normal allocation schedule would capture.
