Goodwill arises when a business is bought for more than the fair value of its identifiable net assets, and it sits on the balance sheet as the unexplained remainder of the price. Goodwill impairment testing asks the uncomfortable follow-up question: is that premium still supported by what the acquired business now earns? Unlike most assets, goodwill cannot be sold separately or observed in a market, so the answer always rests on management's own forecasts.
When goodwill impairment testing is required
- Annually, where the framework requires it, whether or not anything looks wrong.
- Whenever there is an indicator: lost customers, a key person leaving, missed forecasts, a market downturn, regulatory change.
- After a restructuring that changes how the acquired business is managed or monitored.
- Where the carrying amount of the unit exceeds its market capitalisation implication for a listed group.
How the test works, and where it bends
Goodwill is allocated to the cash-generating units expected to benefit from the acquisition, and each unit's carrying amount is compared with its recoverable amount — broadly the higher of what it could be sold for and what it is worth in use. Value in use is a discounted forecast, which is where judgement enters: growth rates, margins, the discount rate and the terminal value. Small, defensible-sounding changes to any of those move the answer by a lot, and that sensitivity is exactly what auditors and regulators test. The honest protection is to disclose the key assumptions and what they would have to become for an impairment to arise.
Impairment of goodwill cannot be reversed in later years under most frameworks, even if the business recovers. That asymmetry is deliberate, and it is why the write-down is resisted and why the decision is scrutinised.
Running a test you can defend
- Define the cash-generating units deliberately, and keep the definition stable between years.
- Base forecasts on the approved budget rather than on a model built for the test.
- Document the discount rate derivation, not just the number.
- Cap growth beyond the forecast period at something defensible for the market.
- Run sensitivities and record them, including the point at which an impairment appears.
- Keep the whole file — inputs, approvals and reasoning — because the next test is judged against this one.
Ettex Records keeps that file structured: one record per cash-generating unit with the allocated goodwill, the assumptions used each year, the sensitivity results and who approved them. Holding the history in one place is what lets somebody explain why last year's growth assumption changed, which is the first question asked.
Frequently asked
Is goodwill amortised or impaired?
It depends on the framework. Some require annual impairment testing with no amortisation; others amortise over an estimated life and test when indicators arise. Check which applies before designing the process.
Can an impairment be reversed?
Generally not for goodwill, even if performance recovers. Impairments of other assets can sometimes be reversed, which is a common point of confusion.
What usually triggers an impairment in a small group?
Losing a customer or contract that justified the acquisition price, or the departure of the people whose relationships were being bought. Both are foreseeable, and both should be in the indicator list.
