Goodwill acquired in a business combination is not amortized under IFRS and must be tested for impairment at least annually, or more frequently if there are indicators of impairment. IAS 36 produced by the International Accounting Standards Board IFRS Foundation sets the authoritative framework, and academic analysis by Christopher Nobes University of Oxford explains the rationale for focusing on recoverable amounts rather than systematic amortization. The key practical step is allocation of goodwill to the smallest group of assets that generates cash inflows largely independent of other assets, commonly referred to as a cash-generating unit.
When to test
A company performs an impairment test annually for each cash-generating unit or group of units containing allocated goodwill and whenever external or internal evidence suggests potential impairment. Market declines, adverse regulatory changes, loss of a major customer, or deteriorating macroeconomic conditions in a territory can be such indicators. In jurisdictions with volatile markets or emerging economies, cultural and institutional differences can make indicators appear earlier and require closer monitoring.
Measuring and recognizing impairment
Recoverable amount is the higher of fair value less costs of disposal and value in use. Value in use is determined by discounted future cash flows using reasonable and supportable assumptions about growth rates, margins, and discount rates; management must document these assumptions and their sensitivities. If the carrying amount of the unit exceeds its recoverable amount, an impairment loss is recognized in profit or loss. The loss is first allocated to reduce the carrying amount of goodwill and then to other assets of the unit pro rata. Under IFRS an impairment loss on goodwill cannot be reversed in future periods even if recoverable amounts recover.
Consequences of impairment extend beyond the accounting entry. An impairment charge reduces reported earnings, can affect debt covenants and dividend capacity, and may influence investor perception of management’s acquisition decisions. Environmental risks such as climate-related impacts on cash flow projections or territorial political instability should be reflected in assumptions and disclosures. Transparent disclosure of the carrying amount of goodwill, the basis for recoverable amount estimates, key assumptions and sensitivity analyses is required to enhance trust and comparability and to allow stakeholders to assess the reasonableness of management’s judgments.
