Locked box and closing accounts in a business acquisition: how buyers and sellers manage purchase price risks, leakage and balance sheet date.

Every transaction is handled by a coordinated team of lawyers, legal staff and specialists. In company acquisition matters we look at structure, contract, tax and liability together.
The purchase price is rarely just one fixed number. In a business acquisition the agreement must decide whether the price is based on a locked-box balance sheet or adjusted after closing through closing accounts.
Both models can work well. The locked box creates price certainty from a defined date. Closing accounts reflect the actual position at closing but create more review and dispute effort.
This post complements the focus page on purchase price structure and the post on purchase price adjustment.
Assess whether price certainty or accuracy at closing matters more.

A locked box requires a reviewed or well traceable balance sheet and strict leakage control.
If balance sheet quality or the interim period is uncertain, the buyer should not rely blindly on a locked box. Closing accounts reflect the actual position at closing and can capture working capital, net debt and cash more accurately.
The extra effort is worthwhile especially in seasonal businesses or where working capital fluctuates strongly.
A locked box fits where the reference balance sheet is reliable and leakage is strictly prohibited. The seller receives price certainty and the buyer knows the economic date it assumes. Precise definitions of permitted and prohibited payments are decisive.
The details should be aligned with the warranty catalogue and information rights.
If the balance sheet is not robust or material movements until closing remain open, the financial due diligence should be deepened first. Only then can the parties decide whether locked box, closing accounts or a hybrid model fits best.
A premature model creates later dispute points.
With a locked box, the economic transfer is moved to a fixed date before closing. The purchase price is set on the basis of this reference balance sheet. From that date the seller may not extract value from the company unless the agreement expressly permits certain payments.
The advantage is price certainty. There is no broad purchase price adjustment after closing. The disadvantage is the need for protection: the buyer must be able to trust that no prohibited value leakage occurs between reference date and closing.
Closing accounts calculate the purchase price on the basis of accounts at or near closing. The model captures the actual level of cash, debt and working capital. It is therefore more accurate but more prone to disputes on interpretation.
Clear accounting principles, a binding objection process and a neutral expert for disputes are essential. Without these rules the conflict is merely shifted to the period after closing.
The choice of model depends on balance sheet quality, risk and desired price certainty.
| Point | Meaning | Contract solution |
|---|---|---|
| Locked box Locked box | Price certainty from reference date | Leakage is overlooked |
| Closing accounts Closing accounts | Actual position at closing | Dispute about accounting items |
| Hybrid model Hybrid model | Targeted adjustment of selected items | Mechanics become too complex |
| Seasonal business Seasonal business | More precise closing calculation | Reference date distorts result |
| Stable figures Stable figures | Efficient locked box | Leakage clause too weak |
Caution with leakage: A locked box is only as good as its leakage rules. Prohibited payments, special bonuses, intra-group fees or hidden withdrawals must be precisely regulated. Otherwise the buyer pays for value that has already left before closing.
Before choosing the model, review annual accounts, interim accounts, trial balances, working-capital analysis, cash positions and intra-group charges. In addition, a list of permitted payments until closing is needed.
The legal review translates these figures into warranties, covenants, indemnities and dispute mechanisms. The SPA warranty catalogue and the disclosure letter must fit this.
Not necessarily. The locked box creates price certainty but can also help the buyer if the reference accounts and leakage protection are sound.
Closing accounts make sense where cash, debt or working capital fluctuate strongly until closing or where the number basis is still uncertain.
Leakage means prohibited value transfers out of the target between the locked-box date and closing. It can include withdrawals, special payments or intra-group charges.
