How Locked Box Confirmation Works
A locked-box transaction begins with a set of historical accounts prepared as of a specified date. The parties use those accounts to establish the financial position and calculate the agreed transaction value. Between the locked-box date and completion, the seller generally operates the business in the ordinary course while complying with restrictions on value extraction.
A confirmation process can then be used to verify relevant information before or around completion. The parties may examine whether prohibited value has moved from the target to the seller or its connected parties, whether permitted payments were properly identified, and whether the financial information remains consistent with the agreed transaction framework.
- Locked-box date: The historical date on which the financial position is used for pricing.
- Reference accounts: The financial statements or accounts used to establish the transaction's economic baseline.
- Leakage provisions: Contractual rules identifying value transfers that are prohibited or permitted.
- Confirmation: Evidence supporting compliance with the agreed financial and contractual conditions.
What Is Being Confirmed
The exact confirmation procedures vary by transaction, but the focus is generally on matters that could change the economic value received by the buyer. This can include dividends, management fees, transaction-related payments, related-party transfers, bonuses, or other movements of value occurring after the locked-box date.
The buyer may also compare transaction records with the reference accounts and supporting schedules. The objective is to establish a clear connection between the agreed purchase price and the financial information underlying that price. Where the agreement expressly permits particular payments, those items are normally distinguished from prohibited leakage.
Locked Box Confirmation and Transaction Evidence
Confirmation procedures can sit alongside other business records used to establish the accuracy and timing of commercial events. For example, a Receipt Confirmation documents acknowledgment that goods or services have been received, while an Order Confirmation records acceptance or acknowledgment of an order. A Delivery Confirmation provides evidence that goods were delivered to the specified recipient.
These records serve different purposes from a locked-box confirmation, but they can contribute to a broader transaction evidence trail. In an acquisition involving significant operating activity, underlying transaction records may help finance teams reconcile revenues, expenses, working capital movements, and related-party transactions with the financial information used in the deal.
Leakage and Permitted Payments
Leakage is a central concept in locked-box transactions. It generally describes value transferred from the target business to the seller or specified connected parties after the locked-box date when that transfer is not permitted under the transaction agreement. Because the purchase price is typically fixed by reference to historical accounts, the buyer relies on contractual protections to preserve the economic value established at the locked-box date.
Not every payment to the seller or a related party necessarily constitutes leakage. The agreement may identify specific permitted payments, such as an expressly agreed dividend or transaction expense. A confirmation therefore needs to be assessed against the definitions, schedules, and exceptions contained in the relevant transaction documents.
Practical Example
Assume a buyer agrees to acquire a company for $50M based on accounts dated December 31, 2025. Completion occurs on March 31, 2026. During the intervening period, the seller makes a $500,000 payment to a related entity that is not listed as a permitted payment in the acquisition agreement.
If the payment qualifies as leakage under the agreement, the buyer may have a contractual claim for the relevant amount. A locked-box confirmation process can help identify and document the payment by comparing bank records, general ledger entries, related-party transactions, and management representations with the agreed leakage provisions.
Best Practices for Locked Box Confirmation
Effective confirmation procedures depend on clearly defined transaction terms and a reliable evidence trail. Finance teams should understand precisely which accounts establish the locked-box position and which subsequent transactions require review.
- Document the locked-box date and reference accounts used for pricing.
- Maintain a detailed schedule of permitted payments and agreed exceptions.
- Reconcile relevant post-lock-box transactions to accounting records and bank activity.
- Review related-party transactions and other transfers of value against the agreement.
- Retain supporting evidence for confirmations, representations, and identified exceptions.
Summary
Locked Box Confirmation supports the financial and contractual integrity of a locked-box M&A transaction. It helps establish whether the agreed pricing baseline remains protected from prohibited value transfers between the locked-box date and completion. By connecting financial records, transaction evidence, and contractual provisions, the process supports informed deal execution and financial decision-making.
