What it means
When a company is bought, the buyer records every asset and liability it acquires at fair value: the buildings, equipment, inventory, receivables, and also intangibles the target never recorded, such as brands, patents, customer contracts and technology. The total of those net assets is almost always less than the price paid, because a functioning business is worth more than the sum of its parts.
The difference is goodwill. It is an accounting balancing figure, but it corresponds to something real: the premium a buyer will pay for an assembled, operating business with customers and momentum.
Goodwill is unusual among assets because it cannot be sold separately, has no determinable life and cannot be measured directly after the acquisition. Standards once required it to be amortised over a fixed period, typically 20 to 40 years, which produced a steady charge unrelated to whether the acquired business was doing well.
Since the early 2000s, IFRS and US GAAP have instead required an annual impairment test: the carrying value of each business unit including its goodwill is compared with its recoverable amount (essentially what it is worth, based on discounted cash flows or market multiples), and if the recoverable amount is lower, goodwill is written down. Once written down, it cannot be written back up.
The impairment test rests on management's forecasts and discount rates, so it involves judgement and is closely examined by auditors and analysts. Large impairments usually follow an acquisition made at the top of a cycle, a change in strategy or a deterioration in the acquired business, and they often arrive in bunches when a new chief executive clears the decks.
Because the charge is non-cash, it does not affect cash flow, but it does reduce equity, can breach covenants based on net worth, and signals that capital was misallocated. Internally generated goodwill, the value a company builds in its own brand and relationships, is never recorded.
That asymmetry means a company that grows organically shows no goodwill while an identical company built by acquisition shows a great deal, and comparisons of return on assets between the two must allow for it.
In practice
Real-world examples.
Example
A software company pays $200 million for a start-up with $15 million of identifiable net assets and records $185 million of goodwill, most of the price being for the team and the technology's future.
Example
A retailer that has grown entirely by opening its own stores shows no goodwill on its balance sheet, while a rival of the same size built by acquisition shows $500 million.
Example
A mining company writes off $2 billion of goodwill after commodity prices fall and the mines it acquired at the peak are no longer expected to earn their carrying value.
Think of it
“Goodwill is like the extra you pay for a popular restaurant beyond the value of its equipment-you're paying for the reputation and loyal customers.
Formula
Calculation
Goodwill = Purchase Consideration minus Fair Value of Identifiable Net Assets Acquired
Impairment Loss = Carrying Amount of the cash-generating unit (including goodwill) minus Recoverable Amount, if positive
Worked example. A logistics group buys a regional courier company for $50,000,000 in cash. At acquisition the courier's identifiable assets and liabilities at fair value are:
- Vehicles and equipment: $12,000,000
- Receivables and other current assets: $6,000,000
- Customer contracts (an intangible the courier never recorded): $9,000,000
- Brand name: $3,000,000
- Liabilities: $10,000,000
- Fair value of identifiable net assets = $12,000,000 + $6,000,000 + $9,000,000 + $3,000,000 minus $10,000,000 = $20,000,000
Goodwill = $50,000,000 minus $20,000,000 = $30,000,000
Three years later, the courier has lost its largest customer and the group tests the courier unit for impairment. The unit's carrying amount, including remaining goodwill and intangibles, is $38,000,000. Management's discounted cash flow forecast gives a recoverable amount of $26,000,000.
- Impairment loss = $38,000,000 minus $26,000,000 = $12,000,000
- The loss is charged against goodwill first, reducing it from $30,000,000 to $18,000,000
The group's profit for the year falls by $12,000,000 and its equity by the same amount, with no effect on cash.Case study
Seen in the real world.
A marketing services group made eleven acquisitions in five years at an average of 12 times earnings, building $340 million of goodwill on a balance sheet with $420 million of equity. Each year the impairment test passed, supported by forecasts that assumed the acquired agencies would grow 10% a year. When a recession cut client budgets, the new chief executive commissioned an independent review of the forecasts.
Actual growth had averaged 2%, three agencies had lost their founders and most of their key clients after earn-outs ended, and two were loss-making. The revised test produced a $190 million impairment, more than half the goodwill.
The share price fell 30%, the company breached a net worth covenant and had to renegotiate its debt, and the chief executive told shareholders that the group had paid for growth that was never going to arrive. The group thereafter capped acquisition prices at 8 times earnings, structured half of every price as a three-year earn-out and required the acquired founders to remain for five years.
Watch out
Common mistakes.
- Treating goodwill as a sign of strength. It is the price paid above net assets, and it is only worth what the acquired business earns.
- Assuming an impairment is a cash loss. It is a non-cash write-down, but it signals that the cash was overpaid in the first place.
- Relying on optimistic forecasts to pass the impairment test year after year until the correction becomes enormous.
Questions
People also ask.
Why is goodwill not amortised?
Because standard setters concluded that a fixed amortisation period bore no relation to the value of the acquired business. Impairment testing was chosen instead, although some frameworks for private companies still permit amortisation.
Can goodwill increase after acquisition?
No. It is fixed at acquisition and can only decrease through impairment.
What is negative goodwill?
When the price paid is less than the fair value of net assets acquired, a bargain purchase. After rechecking the valuations, the gain is recognised immediately in profit.
