What goodwill is, and what a write-down tells you
Goodwill is one of the most misunderstood lines on a balance sheet. In everyday English the word suggests reputation or customer loyalty. In accounting it has a narrower meaning: the part of an acquisition price that can't be assigned to any specific asset.
Once you know how the number is calculated, it becomes clear why a goodwill write-down is one of the more candid disclosures a company makes, even though no cash changes hands when it happens.
Where the number comes from
When one company buys another, the buyer has to record what it acquired. Accounting rules require it to measure every identifiable asset and every liability at fair value as of the acquisition date. The seller's book values don't carry over.
That process covers more than most people expect. Buildings and equipment get new valuations. So do intangible assets the seller may never have recorded, such as brand names, customer relationships, patents, research in progress and favorable leases. Anything that can be identified and valued on its own goes on the balance sheet as a separate asset, and most of those are amortized over their useful lives.
Whatever is left over is goodwill.
Purchase price − fair value of identifiable net assets = goodwill
Here is an example. A buyer pays $500 million for a company. The target's identifiable assets are worth $430 million at fair value. That figure includes $90 million of customer relationships and brand names that never appeared on the target's own books. The target also has $50 million of liabilities, so its identifiable net assets come to $380 million. Goodwill is the remaining $120 million.
That $120 million pays for things that have value but can't be separated out: a trained workforce, which accounting doesn't allow as an asset; cost savings the buyer expects from combining the two businesses; the value of an operation that already runs. It can also include an amount the buyer overpaid.
Why it stays on the books
Under US GAAP, public companies don't amortize goodwill. It stays on the balance sheet at its original amount and is tested for impairment at least once a year, and sooner if something suggests the business has weakened.
Standard-setters have debated this approach for years. Before 2001, goodwill was amortized on a fixed schedule, and private companies can still elect that treatment. Amortization produces a steady annual charge that says little about whether the deal worked. Impairment testing produces no charge while the business performs and a large one when it doesn't, so the charge is less predictable but tells investors more.
The test compares the carrying amount of the business unit, including its goodwill, with the unit's fair value. If the carrying amount is higher, the company writes off the difference, up to the amount of goodwill on the books. A write-down can't be reversed later, even if the business recovers.
What a write-down means
When a company records a goodwill impairment, management is stating in an audited filing that the company paid more for a business than the business turned out to be worth.
Few other entries on the income statement carry that kind of admission. The charge doesn't involve cash, since the purchase price was paid years earlier, and companies usually leave it out of "adjusted" earnings. For forecasting future cash flow that's a reasonable choice. It also explains why these charges often get little attention in coverage, even though they say a lot about past decisions.
Some of the largest impairments on record followed deals that were celebrated when they were announced. AOL Time Warner recorded roughly $99 billion of goodwill impairment in 2002, about two years after the merger closed. The value was lost when the price was agreed. The write-down recorded that loss after the fact.
How to read one as an investor
Three questions help put a write-down in context.
How big is it compared with the original price? Writing off all $120 million of the goodwill in our example means the acquisition failed. Writing off $20 million means the business fell short of the plan.
How soon after the deal did it come? A charge within two years suggests the due diligence or the forecasts were wrong from the start. A charge eight years later may reflect changes in the industry.
Does it keep happening? A company that buys businesses regularly and writes down goodwill every few years is showing you how it prices acquisitions. That pattern is worth weighing when you judge management, whatever the adjusted figures say.
It also helps to look at how much goodwill remains. If goodwill makes up a large share of a company's total assets, much of its balance sheet depends on acquired businesses continuing to perform, and on management's own yearly judgment that they still do.
The terms involved
A handful of words cover most of the discussion about acquisitions. Goodwill is the unassigned remainder of the price. Impairment is the write-down when that value can't be recovered. Amortize means spreading a cost over an asset's useful life. Valuation is the estimate behind the price in the first place. Dilution is what happens to existing shareholders when a company pays for a purchase with new stock.
These words appear in Guess Macro for the same reason they appear in deal coverage: each one says in a single word what would otherwise take a sentence. The archive has the questions that used them, and the glossary defines each one.
Common questions
Is goodwill depreciated or amortized?
Neither, for US public companies. Goodwill is not written down on a schedule the way a building is depreciated or a patent amortized. It stays on the balance sheet at its original amount and is tested for impairment instead, so it falls only when the acquisition is judged to be worth less than was paid. Private companies in the US may elect to amortize it.
How is goodwill calculated?
It is the part of an acquisition price that cannot be assigned to anything specific. The buyer measures every identifiable asset and liability at fair value on the acquisition date, including intangibles the seller may never have recorded, such as brand names, customer relationships and patents. Whatever of the purchase price is left over becomes goodwill.
What does a goodwill write-down tell you?
That the acquisition is not delivering what was expected. No cash moves when it happens, which is why it is easy to dismiss, but it is management conceding in public that it paid more than the business turned out to be worth.
