EXECUTIVE SUMMARY
The Locked Box mechanism delivers price certainty and accelerated closing, but transfers economic risk to the buyer from the Lockbox Date. The definition of “Leakage” is the single most important negotiated term, and loose drafting costs the buyer directly from the price.
The Locked Box mechanism has become the preferred structure in many European and Gulf M&A transactions, given the price certainty and accelerated closing it delivers. But it carries risks the buyer should not underestimate, and the definition of “Leakage” within it may be the single most important negotiated term in the entire agreement.
In this article, we examine the mechanism in depth, when to choose it over Completion Accounts, and how to draft it to achieve balanced protection for both parties.
- The Fundamental Difference Between Locked Box and Completion Accounts
Two different models for determining the final price:
▪ Completion Accounts: the price is determined based on financial statements prepared as at the closing date. Advantage: the price reflects the actual state of the company at closing. Disadvantage: requires detailed post-closing financial audit, and can create disputes over accounting items.
▪ Locked Box: the price is determined based on Reference Accounts predating the closing, and is fixed from the “Lockbox Date.” Advantage: no post-closing disputes over accounting items. Disadvantage: risks that materialize between the Lockbox Date and closing fall on the buyer.
Locked Box is typically preferred when:
▪ Recent financial statements are reliable and audited.
▪ The company’s operations and valuation are likely to remain stable between signing and closing.
▪ Both parties want accelerated closing and to avoid post-closing disputes.
- The Lockbox Date and Its Legal Significance
The Lockbox Date is the date to which the Reference Accounts relate for purposes of price determination. From this date onward:
▪ Any profit or cash generated by the company becomes the buyer’s economically (even though legal ownership transfers only at closing).
▪ Any loss or value decline is borne by the buyer.
▪ Any “leakage” of value from the company to the seller or related parties triggers indemnification.
The core point: the buyer assumes the company’s economic performance from the Lockbox Date, which is why rigorous protection is required.
III. Leakage — Definition Is Everything
“Leakage” is any value flowing out of the company to the seller or its related parties between the Lockbox Date and closing. A narrow, specific definition protects the buyer, while a loose one costs millions.
Forms of leakage that must be covered:
▪ Dividends or profit distributions in any form.
▪ Unusual bonuses to board members or senior management connected to the seller.
▪ Related-party transactions on non-arm’s-length terms.
▪ Waiver by the seller or related parties of debts owed to the company.
▪ Asset transfers from the company to the seller.
▪ Advisory fees to the seller or related parties.

- Permitted Leakage
Certain transactions are considered ordinary and not deemed leakage. These must be defined precisely in the agreement:
▪ Ordinary salaries and bonuses per the company’s pre-Lockbox policy.
▪ Ordinary commercial transactions between the company and seller on documented arm’s-length terms.
▪ Ordinary repayment of commercial debts existing before the Lockbox Date.
Anything outside this list is leakage triggering indemnification.
- Warranties and Leakage Indemnity
The protection mechanism consists of three layers:
▪ An express Warranty from the seller that no leakage has occurred since the Lockbox Date.
▪ A Covenant that no leakage will occur until closing (other than Permitted Leakage).
▪ A dollar-for-dollar Indemnity from the seller for any leakage — without caps and without de minimis thresholds.
These three layers are essential: the warranty is tested at closing, the covenant governs the transition period, and the indemnity defines the remedy.
Core Takeaway
The definition of “Leakage” in a Locked Box agreement is the single most important negotiated term in the entire agreement. Loose drafting costs the buyer directly from the price; rigorous drafting protects the deal from any improper outflow.
Investing in carefully drafting this clause — with comprehensive lists of permitted and prohibited transactions — is the difference between a successful Locked Box and a costly one.
