What is the difference between closing accounts and locked box?

Closing accounts and locked box are two fundamentally different purchase price mechanisms in M&A transactions. In closing accounts, the final purchase price is determined after completion of the transaction based on current figures, while locked box sets the purchase price at a historical date with fixed assumptions. The choice between the two mechanisms affects risk allocation, timing and complexity of the entire transaction process.

What is the difference between closing accounts and locked box mechanisms?

Closing accounts determines the purchase price retrospectively based on the actual financial position on the closing date, while locked box predetermines the purchase price on a historical reference date. This fundamental difference in timing creates different risk profiles for buyer and seller.

In closing accounts, the seller bears the risk of changes in value until closing. The buyer gets certainty about what he is actually buying, but must accept that the final price is not known until closing. This mechanism requires a thorough analysis of the balance sheet and working capital at closing date.

Locked box, on the other hand, sets the purchase price based on historical, audited figures. The buyer bears the risk of changes in value from the locked box date, but gets price certainty during negotiations. This mechanism works with leakage protection to prevent unauthorised value outflows.

How does the closing accounts mechanism work in practice?

The closing accounts mechanism determines the final purchase price by applying adjustments to a base price based on the actual financial position at closing date. Accountants play a crucial role in preparing and verifying these closing accounts within a predetermined period after closing.

The process starts with establishing reference figures during negotiations, such as normalised working capital and cash positions. After closing, actual figures are compared with these references. Deviations lead to purchase price adjustments according to pre-agreed mechanisms.

Timing is critical: closing accounts must usually be prepared within 30-90 days of closing. Disputes over these figures are often referred to an independent auditor. This process can lead to additional payments or refunds between parties, depending on the company's actual performance.

What exactly does a locked box structure entail?

Locked box sets the purchase price based on audited financial figures at a historical date, usually the latest financial statements or a recent interim balance sheet. From this locked box date, no value may flow out of the company to the seller except through predefined permitted leakage.

The structure works like a locked box: the buyer buys the company including all value developments from the locked box date. This means that growth and profits after this date accrue to the buyer, but also that losses and depreciation are for the buyer's account.

Leakage protection is at the heart of this mechanism. Prohibited are, for example, dividend payments, management fees above market level, or other transactions that extract value. Permitted leakage usually includes normal operating expenses, regular salaries and pre-agreed management fees. When prohibited leakage is detected, the purchase price is reduced euro for euro.

What are the advantages and disadvantages of closing accounts versus locked box?

Closing accounts offers the buyer certainty about what he is actually buying, as the price is adjusted to reflect the current situation. For the seller, however, this means uncertainty about the final yield and potential discussions about working capital normalisation. The mechanism is transparent but administratively intensive.

Locked box gives both parties price certainty during negotiations and often speeds up the closing process. The seller knows exactly what he receives, while the buyer benefits from all value developments after the locked box date. The disadvantage is that the buyer buys blind for the period after the reference date.

Complexity varies considerably: closing accounts require extensive working capital analyses and post-closing reconciliations. Locked box requires intensive leakage monitoring and clear agreements on permitted transactions. Costs are often higher in closing accounts due to longer auditing processes, while locked box requires more preliminary work in the M&A phase.

When do you opt for closing accounts and when for locked box?

Closing accounts suit transactions where working capital fluctuates widely, seasonal businesses, or situations where the buyer wants maximum certainty on the value purchased. This mechanism works well in smaller deals where parties are willing to invest time in post-closing processes.

Locked box is suitable for stable companies with predictable cash flows, larger transactions where speed is crucial, or when selling to private equity parties accustomed to this mechanism. It works optimally when recently audited figures are available and management is reliable.

Market conditions also play a role: in a seller's market, sellers often prefer locked box for price certainty. In a buyer's market, buyers have more bargaining power to force closing accounts. Sector-specific factors such as regulation, seasonality and working capital intensity also influence the choice between the two mechanisms.

How does the choice between mechanisms affect the M&A process?

The mechanism choice determines the structure of due diligence, negotiations and documentation. Closing accounts requires in-depth working capital analysis during due diligence, while locked box focuses on leakage identification and management systems for post-signing monitoring.

Negotiations differ fundamentally: closing accounts focus on standardisation methodologies and reference figures. Locked box negotiations focus on permitted leakage definitions and monitoring mechanisms. Documentation complexity varies, with closing accounts requiring more post-closing procedures and locked box more conditional provisions.

Timing impact is significant: locked box can speed up the process through price certainty early in the process. Closing accounts lengthens the process through post-closing reconciliations but offers more flexibility during negotiations. Risk allocation shifts fundamentally, affecting insurance, warranties and indemnities in transaction documentation.

Choosing between closing accounts and locked box mechanisms requires strategic consideration of risk, timing and complexity.
