Locked Box Mechanism
Definition
A pricing mechanism in M&A transactions where the purchase price is fixed based on a set of accounts prepared at a specified date prior to completion, with value leakage protections to ensure no value is extracted from the target between the locked box date and closing. Locked box mechanisms provide price certainty and avoid the disputes often associated with completion accounts adjustments.
Complementary Terms
Concepts that frequently appear alongside Locked Box Mechanism in practice.
The contractual framework in an M&A transaction that determines how the final purchase price is calculated and adjusted to reflect the financial position of the target at closing. The two principal mechanisms are completion accounts (which adjust the price post-closing based on actual financial metrics at the completion date) and locked box (which fixes the price based on a historical balance sheet date with no post-closing adjustment).
A contractual arrangement in an M&A transaction where a portion of the purchase price is contingent on the acquired business achieving specified financial or operational targets during a defined period following completion. Earnouts bridge valuation gaps between buyer and seller, incentivise seller retention and performance, and reduce buyer risk.
A mechanism used in M&A transactions where the final purchase price is adjusted after closing based on the target company's actual financial position — typically net assets, working capital, debt, and cash — as at the completion date. Completion accounts are prepared post-closing and compared against agreed targets, with adjustments settling the difference between estimated and actual values.
The agreed level of working capital that the target business should have at the completion of an M&A transaction, established during negotiations and used as a benchmark for purchase price adjustments under a completion accounts mechanism. The target is typically set at the average net working capital over a 12-month trailing period, normalised for seasonality and non-recurring items.
A mechanism in M&A transactions that adjusts the purchase price based on the difference between actual working capital at closing and a pre-agreed target level. Net working capital adjustments ensure the buyer receives the agreed level of operating liquidity and are a standard feature of enterprise value to equity value bridge calculations.
A portion of the purchase price in an acquisition that is payable at a future date, either as a fixed amount or contingent on the achievement of specified milestones. Deferred consideration must be recognised at fair value at the acquisition date under IFRS 3 and ASC 805, with subsequent changes in value typically recorded through profit or loss.
A target level of net working capital agreed between buyer and seller in an acquisition, used as the basis for post-closing purchase price adjustments. The working capital peg ensures the buyer receives a business with a normalised level of operating liquidity, with adjustments made if actual working capital at closing is above or below the agreed amount.
A third-party account established at closing of an M&A transaction to hold a portion of the purchase price (typically 5-15%) for a specified period, providing the buyer with security against potential warranty claims, indemnity obligations, or purchase price adjustments. The escrowed funds are released to the seller upon expiry of the escrow period or resolution of any outstanding claims.
