Goodwill impairment testing

Goodwill is tested for impairment at the reporting unit level under ASC 350, comparing fair value with carrying amount, while private companies may elect to amortize goodwill and test only on triggering events.

CORAA TeamUpdated November 5, 2026

Definition

Goodwill is not amortized by most entities. Under ASC 350-20, it is tested at least annually, and between tests when events make impairment more likely than not, at the reporting unit level. Entities may begin with a qualitative assessment. If a quantitative test is needed, the carrying amount of the reporting unit is compared with its fair value, and the impairment loss equals the excess of carrying amount over fair value, limited to the goodwill balance (ASU 2017-04 removed the second step). Private companies may elect the alternative that amortizes goodwill on a straight-line basis over ten years or less and tests only when a triggering event occurs.

Why it matters in an audit or review

Fair value estimates are sensitive to discount rates, growth, and market multiples, so auditors challenge assumptions and often involve a specialist under AU-C 620. Reporting units, cumulative losses, and headroom drive the risk.

Example

(Illustrative) A reporting unit has a carrying amount of $12.0 million, including $4.0 million of goodwill, and a fair value of $10.5 million. The loss is $1.5 million.

Common mistakes

  • Not testing after a triggering event, such as loss of a major customer.
  • Using a single entity-level test without reporting units when the private company alternative has not been elected.
