Current assets minus current liabilities — but with cash pulled out of the assets and debt pulled out of the liabilities, because those two already ride the net-debt part of the bridge. Count them here too and you would hit the price twice for the same dollars. Today: that number is not simply read off the sheet — it is produced by applying an accounting methodology to it, and the methodology is negotiated.
The working-capital true-up takes the softest numbers on the balance sheet — reserves, accruals, cutoffs — and settles them in cash, months after the handshake. The methodology is the price.
Already fluent in the peg and the post-closing true-up? Skip to the worked statement ↓
A company's balance sheet on the closing date is fixed to the penny — every account frozen, the deal has no collar or threshold. Can the working-capital adjustment still swing the purchase price by hundreds of thousands of dollars?
Commit to a guess, then read on. The frozen balance sheet is only the raw material. The adjustment is not read off it — it is built by applying an agreed accounting methodology (which items count, which reserves, GAAP or the company's past practice) to those frozen accounts. Change one soft judgment — an allowance, an accrual — and the same balance sheet yields a different working-capital number and a different check. The worked statement below shows the two-step true-up, and then the completion problem shows a single accounting judgment moving $400K.
The last bridge lesson ended on a one-line villain: “−$2.0M NWC Adjustment,” a true-up to what the company actually delivered. That single line hides the most quietly contested mechanic in a private acquisition. Its job is to make sure the seller hands over a business stocked with its normal level of short-term operating capital — enough receivables, inventory, and prepaids, net of the payables and accruals it runs on — so the buyer does not wake up on day one having paid full price for a company the seller quietly drained of its working capital on the way out the door. The mechanic that guards against that is net working capitalDefined termFor a deal, current assets excluding cash minus current liabilities excluding debt. Cash and debt are excluded because they are settled separately in the net-debt part of the price bridge; counting them here would double-count., measured against a target and trued up in cash. And every input to it is an accounting judgment.
Start with what NWC is, precisely, because the exclusions are the whole game. It is current assets minus current liabilities — but you strip cash out of the assets and funded debt out of the liabilities. Why? Because Lesson 010 already paid for cash and debt on their own lines of the bridge (cash added back, debt subtracted). Leave them inside working capital and you would move the price twice for the same dollars. So NWC is the operating squeeze of the balance sheet: receivables, inventory, and prepaids on one side; payables, accrued expenses, and deferred revenue on the other. Nothing financial, only what the business needs to turn its next month.
Against that number sits the pegDefined termThe target working capital the seller must deliver at closing, usually built from a normalized trailing 6- or 12-month average, with one-time anomalies scrubbed out. Also called the target or reference working capital. — the target both sides negotiate before closing, typically a normalized trailing average of the company's own working capital, so it reflects the normal level the business runs on. Deliver less than the peg and the price drops dollar-for-dollar; deliver more and the surplus is extra price to the seller. But here is the catch that makes this a lane-E lesson: the peg is a number the balance sheet never prints. It is constructed. And the closing statement that gets measured against it is constructed the same way — by applying an accounting methodology to the frozen accounts. Watch the two-step settlement.
The balance sheet is the raw material; the working-capital methodology is the price.
A deal's peg is $10.0M. When the books close, the actual working-capital statement shows $11.2M. The agreement has no collar or de minimis threshold. Which way does the adjustment run, and how much?
Now the lane-E move. Every number in that statement — receivables, inventory, accruals — looks like a hard fact, but each carries a judgment. How large an allowance for doubtful accounts nets down the receivables? What reserve writes down slow inventory? Which expenses are accrued, and as of what cutoff? Those judgments are accounting, and accounting has range. So the agreement does not just say “compute working capital” — it dictates how: the closing statement must be prepared “consistent with the company's past practice” or “in accordance with GAAP, consistently applied,” using the same methodology that built the peg. That consistency clause is the point. It forces an apples-to-apples comparison, because if the peg is measured one way and the closing statement another, the difference between the two is not a change in the business — it is a change in the accounting, and it is paid in cash.
Which is exactly where deals fight. Buyers push for “GAAP, consistently applied,” hoping to correct a historical treatment they think was too generous; sellers push for “consistent with past practice,” wanting the number computed the way it always was, the way the peg was set. When GAAP and past practice diverge on a soft line, real money rides on which one governs. It is not academic: working-capital adjustments are routinely described as the single most common source of post-closing purchase-price disputes, and when the parties cannot agree, the agreement hands the question to an independent accounting firm whose determination is binding, with its fees split in proportion to how the disputed dollars fall. In one real Delaware dispute, Penton Business Media Holdings v. Informa, the buyer argued the company's historical accounting did not comply with GAAP and tried to change it in the closing numbers — and the courts had to sort out whether the deal's independent accountant even had the authority to make that call. That is the caliber of fight one word in a methodology clause can start.
Your turn · one accounting judgment, in dollars
| Line | Work it | Amount |
|---|---|---|
| Allowance in the peg methodology | historical practice | $200K |
| Allowance in the buyer's statement | “GAAP requires it” | $600K |
| = Change in the allowance | 600 − 200 | +$400K |
| = Effect on closing NWC vs. peg | net receivables fall by… | ? — you |
| = Effect on the seller's proceeds | dollar-for-dollar off the peg | ? — you |
A larger allowance writes receivables down $400K, so current assets fall $400K, so closing NWC falls $400K below the peg — and the price drops $400K off the seller's check. Not one receivable changed and not one dollar of cash moved; a single accounting judgment did all of it. This is why the methodology clause is the real battleground: the seller argues the historical $200K governs (“consistent with past practice”), the buyer argues GAAP demands $600K, and if they cannot agree, an independent accountant decides — with $400K of purchase price riding on the answer.
The assumption: “Working capital is an accounting fact. You read current assets minus current liabilities off the closing balance sheet, and the lawyers just plug the number in.”
Why it's wrong: the deal number is constructed, not read. It is what you get by applying a negotiated methodology to the frozen accounts — which current items count, which reserves and accruals, GAAP or past practice, as of which cutoff — and the soft, judgment-heavy lines (allowances, obsolescence reserves, accrual timing) are exactly where the same balance sheet yields different working capital and different cash. The balance sheet is the raw material; the methodology is the price. Read only the number and you will never see that a one-word change in a definitions schedule — “GAAP” versus “past practice” — just moved the seller's proceeds.
On EDGAR, pull one real acquisition or stock-purchase agreement (open the Exhibit 2.1 to an 8-K, or the merger agreement in a proxy). Find the purchase-price adjustment section and the definition of “Net Working Capital” (or “Working Capital”), then find the sentence dictating how the closing statement is computed — the “consistent with past practice” or “GAAP, consistently applied” language. Pick one judgment item its methodology controls — an allowance for doubtful accounts, an inventory reserve, an accrual cutoff — and write one sentence: if the buyer's accountants took a more conservative view of that item, which way would closing NWC move, and which way would the seller's check move?
Right result: you can point at the methodology clause and at one soft line it governs, and say in one sentence how an accounting judgment on that line becomes cash — the number is now a construction you can read, not a fact you take on faith.

Before you scroll on — in one sentence, why can a frozen balance sheet still move the price?
Working capital in a deal is not read off the balance sheet, it is built by applying a negotiated accounting methodology to it — and that methodology, settled in cash at the true-up, is the price.
