Post-Closing Adjustment
Reconciliation of estimated closing balances (working capital, debt, cash) to final actual amounts, with net difference paid between buyer and seller — typically finalized 60-120 days after closing.
Full Definition
The post-closing adjustment mechanism recognizes that closing-date balance sheets are initially estimates. By the time the deal closes, actual final numbers aren't yet known — AR hasn't been fully invoiced for the period, inventory counts may not be complete, accruals haven't been fully calculated. The purchase agreement provides a process for finalizing these numbers after closing, with true-up payments flowing in either direction.
How it works: (1) Estimated closing statement at closing (working capital, debt, cash); (2) within 60-120 days post-close, final closing statement prepared by buyer; (3) seller reviews and either agrees or disputes; (4) disputed items go to independent accountant for resolution; (5) net difference paid between parties. Disputes happen regularly — working capital methodology, AR reserves, inventory classification, accrual adequacy. Clear purchase agreement language and documented methodology reduce dispute frequency.
Seller vs. Buyer Perspective
Post-close adjustments can reduce your proceeds further after closing. Protect yourself by: engaging your accountant/QoE for the post-close review, documenting your methodology clearly, responding promptly to buyer's proposed calculations, and pushing back on aggressive adjustments. The dispute mechanism (independent accountant) is usually fair but costly — weigh dispute value against fees.
Post-close review is where you capture value the closing estimate missed. Be thorough but fair — aggressive adjustments create disputes and damage relationships. Use specialized accounting resources. Meet deadlines. Most disputes settle at roughly 50-70% of the contested amount; aim for that range in your initial calculation.
Real-World Example
Closing estimated working capital: $2.4M (peg $2.5M, $100K shortfall paid by seller at close). Final closing calculation 75 days post-close: $2.28M (additional $120K shortfall). Seller disputes $60K (AR reserves), agrees to $60K. Parties settle at $100K additional payment. Total working capital adjustment: $200K from $22M enterprise value.
