Key takeaways
- Working capital disputes are usually definition disputes before they are math disputes.
- The seller should defend consistency with historical accounting methods, not only GAAP in the abstract.
- Common disputes involve AR reserves, inventory reserves, deferred revenue, accrued expenses, cutoff, and excluded items.
- A sample calculation and support file should be built before signing.
- The objection process requires specific disputed items, amounts, and evidence.
Disputes are won before the dispute starts
For adjacent context, compare this with Working Capital Peg Mechanics, Closing Statement and Post-Closing True-Up Mechanics, and Deferred Revenue in the Working Capital Peg. Those articles cover the mechanics; this article focuses on dispute defense.
Current purchase price adjustment research emphasizes working capital calculations, closing statements, dispute processes, and accounting definitions.
A seller's best defense is a clear agreement, sample calculation, consistent accounting method, and organized support file.
Post-closing disputes become harder when the seller has not prepared evidence before close.
NWC dispute
A disagreement over the final net working capital calculation or purchase price adjustment
Accounting consistency
Use of the same policies, methods, estimates, reserves, and classifications used historically unless the agreement says otherwise
Objection notice
The seller's formal response identifying disputed items and amounts within the agreement deadline
Working capital disputes often sound technical, but the economics are real. A reserve change, cutoff adjustment, deferred revenue treatment, or inventory write-down can move hundreds of thousands of dollars after closing.
The buyer prepares the final statement after close. The seller should prepare the defense file before close.
Common dispute categories
Most disputes cluster around definitions, reserves, cutoff, and consistency.
The purchase agreement should specify whether calculations follow GAAP, consistently applied historical methods, a hierarchy of policies, or a specific schedule.
The seller support file
The support file should be organized by working capital line item and tied to the sample calculation.
NWC Defense File
- Purchase agreement definitions and sample calculation.
- Historical monthly balance sheets used to set the peg.
- AR aging, collections after close, and reserve methodology.
- Inventory reports, count support, reserve policy, and obsolete inventory analysis.
- AP aging, accrued expenses, payroll, bonuses, taxes, and cutoff support.
- Deferred revenue schedule and cost-to-fulfill analysis.
- List of excluded cash, debt, transaction expense, and non-working-capital items.
- Objection calendar and accountant dispute procedures.
Frequently asked questions
When should the seller build this file?
Before closing, ideally before signing the purchase agreement.
What if the buyer changes accounting estimates?
The seller should compare the change to historical practice and the agreement hierarchy.
What is the biggest mistake?
Negotiating the peg number without negotiating the calculation method and support process.
