Closing Mechanics

Closing Statement and Post-Closing True-Up Mechanics in M&A

The final purchase price is often not final at closing. The closing statement, post-closing adjustment, objection process, and accountant dispute mechanism determine how cash moves after the deal closes.

Key takeaways

  • The closing statement converts deal definitions into dollars after closing.
  • True-ups often involve working capital, cash, debt, transaction expenses, deferred revenue, inventory, and other purchase price adjustments.
  • The seller should understand the objection deadline, supporting documentation, and independent accountant process.
  • Definitions matter more than labels: GAAP consistency, accounting methods, and sample calculations should be negotiated before signing.
  • A seller should prepare the estimated closing statement before the buyer prepares the final version.

Current purchase price adjustment research highlights how post-closing calculations, working capital adjustments, escrows, and disputes affect final deal economics.

The closing statement is where accounting definitions become cash adjustments.

Sellers should model the calculation before signing, not merely react to the buyer's post-closing statement.

True-up

The payment from buyer to seller or seller to buyer after comparing estimated and final closing amounts

Dispute accountant

The independent accountant or expert appointed to resolve unresolved adjustment disputes

The headline price is negotiated in the LOI. The purchase agreement defines the adjustment mechanics. The closing statement applies those mechanics after closing. If the seller has not modeled the closing statement, the seller may be surprised by cash moving back to the buyer weeks or months after the deal closes.

The closing statement is not bookkeeping. It is a second negotiation conducted with accounting schedules.

What appears on the closing statement

The exact schedule depends on the purchase agreement, but most closing statements include the same core categories.

The agreement should include definitions and sample calculations. If the parties disagree on the accounting method after close, the seller is already in a weaker position.

The objection and dispute process

The purchase agreement usually gives the buyer a period to prepare the final closing statement and the seller a period to object. The objection must be specific and supported.

Frequently asked questions

How long does the true-up take?

Often 60-120 days after closing, depending on the agreement, accounting complexity, and whether disputes arise.

Can the seller dispute the buyer's calculation?

Yes, if the agreement provides an objection process and the seller objects on time with support.

What is the biggest mistake?

Negotiating the working capital peg but ignoring the closing statement mechanics that determine how the peg is actually calculated.
