Contingent Liabilities, Provisions and Legal Reserves
Not every future obligation gets a number on the balance sheet — accounting draws a hard line based on how likely and how estimable a loss is, and where that line falls changes what the reader can see.
Prerequisites: Reading a Balance Sheet
A company being sued for $100m doesn't automatically show a $100m liability. Accounting rules sort uncertain future obligations into three buckets by likelihood, and only one of them gets booked as a real number.
An obligation is accrued as a provision only once a loss is probable and can be reasonably estimated. Anything less likely gets a footnote at best, or nothing at all — so the balance sheet can understate real exposure that's plainly visible if you read past it.
The three-bucket spectrum
Probable — more likely than not to result in a loss, and the amount can be reasonably estimated: accrue a provision, a liability at the best estimate, hitting the income statement immediately. Reasonably possible — more than remote but not probable: no accrual, but disclose the nature and, if estimable, the range of exposure in the footnotes. Remote — unlikely to occur: no accrual and typically no disclosure required at all.
IFRS (IAS 37) and US GAAP use the same three-bucket language but interpret "probable" differently in practice — IFRS treats it closer to "more likely than not" (just over 50%), while US GAAP practice often runs closer to a higher bar in application, which is one reason two companies facing similar litigation, one reporting under each standard, can show very different balance sheets for economically similar risk.
Worked example
A company is sued for $100m in damages. Early on, outside counsel estimates a 30% chance of an adverse outcome, with an expected settlement around $40m if the plaintiff wins. Because 30% doesn't clear the "probable" bar, no liability is accrued — the case is disclosed only as a "reasonably possible" contingency in the footnotes, with no balance sheet impact. Eighteen months later, after a bad ruling on a pretrial motion, counsel revises the odds to 75% and the likely settlement stays around $40m. The loss is now probable and estimable, so the company books a $40m provision — a charge that hits earnings the quarter the assessment changes, even though nothing about the underlying business changed that quarter.
What this means in practice
The jump from footnote disclosure to accrued provision is often abrupt and can look like a surprise earnings hit, even though the underlying risk was disclosed all along for a reader following the footnotes. Analysts tracking litigation-heavy or regulatory-heavy sectors (banks, pharma, tobacco) watch the language in the contingencies footnote quarter to quarter — a shift from "the company believes it has meritorious defenses" to "the company has recorded an accrual" is the accounting system's way of saying the probability assessment just crossed the line.
A company with no litigation liability on its balance sheet is not necessarily litigation-free — it may simply have assessed its exposure as not yet probable. Read the contingencies footnote, not just the balance sheet, to see the exposure accounting rules don't yet require it to book.
