The buyer wants a definitive dollar-for-dollar working capital peg at closing, but our monthly receivables and inventory fluctuate unpredictably. How does structuring a working capital collar protect us from contentious post-closing purchase price disputes?

Question

A standard working capital mechanism establishes a single target dollar amount at closing. If actual net working capital delivered is one dollar below the peg, the buyer docks your purchase price. If it is one dollar above, the buyer owes you cash. In businesses with seasonal demand or fluctuating inventory, this rigid structure invites contentious post-closing adjustments and gives the buyer an incentive to dispute accounting definitions.

A working capital collar solves this problem by creating a deadband around the target peg, usually set between one and three percent of the enterprise value or historical working capital average. If actual working capital lands within this negotiated corridor, no purchase price adjustment occurs in either direction. Adjustments are only triggered if the final delivered balance falls outside the collar, and then only for the dollar amount that exceeds the boundary.

To make this work, the purchase agreement must define net working capital with extreme precision. The contract must explicitly outline which current asset and liability accounts are included, specify that calculations follow the company's historical accounting principles rather than generic GAAP, and mandate that bad debt reserves and inventory obsolescence formulas cannot be altered post-close.

A well-negotiated collar absorbs ordinary operational volatility, protects you from bad-faith post-closing true-up audits, and prevents deal teams from fighting over minor cash swings that have nothing to do with fundamental business performance.
