The working capital adjustment is the least glamorous clause in a purchase agreement and one of the most expensive to get wrong. Buyers and sellers negotiate the headline price for months, then hand the true-up mechanics to whoever is still awake at 2 a.m. the night before signing. Ninety days after closing, that clause quietly moves six figures in one direction or the other.
This corporate concept guide explains what the adjustment does, how the peg gets set, where disputes actually come from, and the drafting choices that decide them. It applies to main-street deals and lower-middle-market deals alike.
What You’ll Learn
What a Working Capital Adjustment Is
A working capital adjustment is a purchase-price mechanism that compares the net working capital delivered at closing against an agreed benchmark, the “peg,” and adjusts the price dollar-for-dollar for the difference. Net working capital, for deal purposes, usually means current assets minus current liabilities, with cash, debt, and taxes carved out by definition.
The logic is simple: the buyer is paying for a business that can operate on day one without a capital infusion. If the seller strips receivables or stretches payables before closing, the buyer inherits a business that needs immediate cash. The adjustment makes the price follow the balance sheet. Public-company purchase agreements filed on SEC EDGAR are a useful free library of how these provisions read in practice.
Setting the Peg: Where the Fight Starts
The peg is supposed to represent the normalized working capital the business needs. The most common formula is a trailing twelve-month average, which smooths seasonality. A retailer pegged off its November balance sheet will look wildly overcapitalized in July; a landscaping company pegged in January will look starved by June.
The peg is not a legal afterthought, it is a valuation exercise. Every dollar the peg moves is a dollar of purchase price. Sellers should model the peg against monthly balance sheets before agreeing to it, which is exactly the kind of analysis that should happen in diligence, not after signing. As we explained in due diligence reprices the deal, the number in the letter of intent rarely survives contact with the data room.
Cash-Free, Debt-Free Deals and the NWC Definition
Most private deals are done “cash-free, debt-free”: the seller keeps the cash and pays off the debt, and the price assumes neither transfers. The working capital adjustment then polices everything in between. The defined terms carry the load, because what counts as “cash,” “indebtedness,” and “current liabilities” decides real money.
- Customer deposits and gift cards: cash the seller keeps, but a liability the buyer services. Debt-like item or working capital? Say so explicitly.
- Accrued PTO and bonuses: frequently negotiated as indebtedness rather than working capital, especially mid-year.
- Aged receivables: include them at face, at reserve, or exclude anything over 90 days. Each choice moves the number.
- Inventory: obsolete stock counted at cost inflates NWC; buyers push for a valuation methodology, not just “GAAP.”
Whether you are doing an asset sale or an equity sale changes which liabilities ride along, so the NWC definition has to match the structure.
The True-Up Timeline: Closing Statement to Final Determination
The mechanics run on a schedule the agreement sets. At closing, the parties settle based on an estimated closing statement. Within 60 to 90 days, the buyer delivers its actual closing statement. The seller then has a review period, typically 30 to 45 days with audit-style access to the books, to object with specificity. Whatever survives negotiation goes to an independent accountant, acting as an expert and not an arbitrator, whose determination on the disputed items is final and binding.
Two design choices matter most. First, whether the accountant can only pick within the range of the parties’ positions, which discourages aggressive statements, or decide each item independently. Second, who pays the accountant; fee-shifting in proportion to the losing positions keeps both sides honest. A working capital adjustment without a tight dispute procedure is an invitation to relitigate the whole deal, the same dynamic we described in earnout disputes.
Five Proven Traps in a Working Capital Adjustment
- 1. “GAAP” without “consistently applied”: if the target never booked reserves, a buyer applying textbook GAAP post-closing manufactures a shortfall. The standard should be GAAP applied consistently with past practice, with an illustrative example schedule attached.
- 2. A peg set at a seasonal peak: the single most common seller loss. Model twelve months before you agree.
- 3. Double-dipping with indemnity: the same unpaid liability claimed once through the true-up and again as an indemnification claim. Add an anti-double-recovery clause.
- 4. No collar, no materiality: dollar-one adjustments generate disputes over rounding errors; a modest collar or deductible keeps the fight above the noise.
- 5. Estimated statement games: if the seller controls the estimate and the buyer’s only remedy is the true-up months later, the seller has an interest-free loan; require good-faith estimates built from the same defined terms.
Negotiating and Drafting Tips for Buyers and Sellers
Sellers: negotiate the peg with your financial advisor before exclusivity, attach an example calculation as an exhibit, and cap the accountant’s discretion to the parties’ ranges. Anticipate the adjustment when you plan proceeds, because the cash you think you are keeping may be working capital the buyer paid for. The tax treatment of purchase-price adjustments also feeds directly into your net outcome; the IRS overview of sale of a business is a readable starting point on how allocations are taxed.
Buyers: insist on the consistency standard plus the example schedule, define debt-like items exhaustively, and tie the estimated statement to access rights so surprises surface before funds flow. If the deal begins with a term sheet, get the peg methodology into it; our guide to the business letter of intent explains which economic terms belong there.

Frequently Asked Questions
Is a working capital adjustment the same as an earnout?
No. The working capital adjustment trues up the price for the balance sheet delivered at closing, looking backward. An earnout pays additional consideration for future performance. They are drafted, disputed, and taxed differently.
What is a typical working capital peg?
Most deals use a trailing twelve-month average of net working capital, adjusted to exclude cash, debt, and non-operating items. Seasonal businesses sometimes use a same-month prior-year comparison instead. The right answer is the one that reflects normalized operations.
Who wins working capital disputes?
Usually the side whose accounting positions match the agreement’s defined terms and past practice. Independent accountants decide item by item, so precise objections supported by workpapers beat broad complaints about fairness.
Next Steps
If you are heading into a sale or acquisition, treat the working capital adjustment as price, not plumbing, and negotiate it with the same energy as the headline number.
