What it means
The behaviour depends on an asymmetry in how people react to bad news. A company reporting a $30,000,000 loss is not judged three times as harshly as one reporting a $10,000,000 loss; both are simply described as a terrible year.
If the extra $20,000,000 of charges makes the next two years look strong, the trade appears attractive to whoever is running the company. The classic moment is a change of chief executive.
An incoming leader has every incentive to write down inventory, impair goodwill, book generous restructuring provisions and reset expectations, because the resulting loss belongs to the predecessor and the recovery will belong to them. Analysts have watched this pattern for decades and often call it a kitchen sink quarter.
Mechanically it works by pulling future costs into the present. Excess provisions become what auditors call cookie jar reserves, quietly released into profit in later periods when they turn out not to be needed.
Written-down inventory that later sells carries almost no cost of sales, and impaired assets generate less depreciation, so the following year's margins improve without anything real changing in the business. The line between judgement and manipulation is genuinely difficult, which is what makes the topic contentious.
Estimating a restructuring provision or testing goodwill for impairment requires assumptions about the future, and reasonable people can differ. It becomes a big bath when the assumptions are chosen for their effect on the earnings profile rather than for their accuracy, and regulators and auditors focus hard on charges that cluster suspiciously in loss-making years.
For anyone reading accounts from outside, the useful defence is to look through the noise. Compare cash flow from operations with reported profit, since a big bath usually involves large non-cash charges that leave cash flow untouched, and check whether last year's provisions are being released into this year's profit.
A company whose earnings swing violently while operating cash flow stays flat deserves a closer look.
In practice
Real-world examples.
Example
An incoming chief executive at a listed engineering group announces a strategic review in her first month and books $220,000,000 of impairments and restructuring charges in the same quarter. Two years later the group reports record margins, partly because the depreciation on the written-down assets fell by $34,000,000 a year.
Example
A software company facing a weak year writes off $9,000,000 of capitalised development costs it had previously argued were valuable assets. Analysts note that the write-off removes $3,000,000 of annual amortisation from each of the next three years, flattering the operating margin.
Example
A bank builds unusually large loan loss provisions during a recession year in which it is already reporting a loss. When defaults come in lower than assumed, the releases add materially to profit in the next two years and the chief financial officer is questioned about the original assumptions.
Formula
Calculation
Reported loss = underlying loss + discretionary charges. Following year's reported profit = underlying profit + provision releases + costs avoided because assets were already written down.
A retailer is heading for an underlying pre-tax loss of $12,000,000 after a poor trading year. A new chief executive arrives and books an additional $18,000,000 of charges: a $10,000,000 restructuring provision, a $5,000,000 inventory write-down and a $3,000,000 goodwill impairment.
The reported loss becomes $12,000,000 + $18,000,000 = $30,000,000. The headlines describe a disastrous year and the share price falls, but expectations are now reset at a very low level.
The following year the business recovers modestly and produces an underlying profit of $5,000,000. In addition, $4,000,000 of the restructuring provision proves unnecessary and is released, and the written-down stock sells at normal prices so cost of sales is $2,000,000 lower than it would otherwise have been.
Reported profit is therefore $5,000,000 + $4,000,000 + $2,000,000 = $11,000,000. The swing from a $30,000,000 loss to an $11,000,000 profit is $41,000,000 and looks like a spectacular turnaround, while the underlying swing from -$12,000,000 to $5,000,000 is only $17,000,000. More than half the apparent recovery came from the accounting, not the shops.Case study
Seen in the real world.
Verity Home Retail is an illustrative, fictional chain of 140 homeware stores that had two poor years and replaced its chief executive. The new leader inherited a business with genuine problems: too many stores, ageing stock and a goodwill balance from an acquisition that had never delivered. Nobody disputed that charges were needed.
The question was how much. Management proposed a $46,000,000 package of provisions and impairments against an underlying loss of $14,000,000. The audit committee challenged three elements in particular: a store closure provision covering twenty-two locations where no closure decision had actually been taken, an inventory write-down assuming an unusually deep clearance discount, and an impairment model using a growth assumption below anything in the board's own plan.
In this fictional case the audit committee cut the package to $31,000,000 and required the store closure provision to be limited to the eleven sites with signed decisions. Reported loss came in at $45,000,000 rather than $60,000,000, and the following year's profit was $6,000,000 rather than a flattered $16,000,000. The chair's view was that a smaller loss followed by a believable recovery served shareholders better than a dramatic swing nobody could interpret.
Watch out
Common mistakes.
- Assuming every large write-down is a big bath. Businesses genuinely do impair assets, and a charge is only suspicious when it is oversized or conveniently timed.
- Judging a recovery year on reported profit alone. Provision releases and lower depreciation can create most of the improvement without any trading change.
- Believing a big bath is always illegal. Much of it lives in the grey area of estimates and assumptions, though deliberately false provisions cross into fraud.
Questions
People also ask.
Why do new chief executives do this?
Because the loss is attributed to their predecessor while the subsequent recovery is credited to them, and expectations are reset low on day one.
How can an outsider spot a big bath?
Compare operating cash flow with reported profit, look for large non-cash charges in a loss year, and watch for provisions released into profit shortly afterwards.
What are cookie jar reserves?
Excess provisions built up in a bad year and released into later periods to smooth or boost reported earnings.
