Goodwill and impairment
What a company records when it pays more for a business than that business's assets are worth. Sooner or later, the accounts have to say whether it was worth it.
Buy a rival for $1bn when its identifiable assets, net of debts, are worth $600m, and the accounts must place the missing $400m somewhere. That somewhere is goodwill.
What it represents
The premium is paid for things the seller's balance sheet never recorded: a brand, a trained workforce, customer relationships, an expectation that the two businesses together are worth more than apart. Some of that is real. Some of it is the winner's curse in an auction.
A company that built the same brand itself records nothing, because the spending was expensed as it happened. This is why an acquisitive company and an organically-grown company with identical economics can show completely different balance sheets and completely different returns on capital.
It is not amortised — it is tested
Unlike a patent, goodwill has no defined life, so it is not written down on a schedule. Instead it must be tested at least annually: is the acquired business still worth at least what is on the books?
If yes, nothing happens and the figure sits unchanged, potentially for decades. If no, the company records an impairment — a one-off charge reducing goodwill and profit.
What an impairment actually tells you
Cash left the company on the day of the acquisition, often years earlier. The impairment changes no cash and no operations. What it does is concede, in public and in numbers, that the price paid cannot be justified by what the business now looks like. The loss occurred at purchase; the accounts are catching up.
Which is why the standard framing — 'a non-cash charge, please ignore it' — gets the emphasis exactly backwards. Ignore it for this year's cash flow. Do not ignore it when assessing whether management can be trusted to allocate capital.
Reading it
- Goodwill as a share of total assets. Above roughly a third, the balance sheet is substantially a record of prices paid rather than assets held.
- A history of impairments. One can be bad luck. A pattern is a capital allocation problem, and it will recur because the same people are making the same decisions.
- Timing. Impairments cluster in bad quarters, when a large charge attracts less attention, and frequently arrive alongside a new chief executive who has every incentive to clear the decks early.
- The footnote. Impairment tests disclose the assumptions used — growth rates, discount rates. Assumptions that look heroic are a warning ahead of the write-down.
Intangibles that are not goodwill
An acquisition also creates identified intangibles — patents, customer contracts, trade names — which do have estimated lives and are amortised. Companies often present adjusted earnings excluding that amortisation, on the reasoning that it reflects a past purchase rather than current operations. That is defensible for a one-off deal and considerably less defensible for a company that acquires continuously, because then the charge recurs as reliably as any other cost. See adjusted earnings.
