Mecanismos de Ajuste de Precio de Compra: Locked Box, Cuentas de Cierre y Earn-Outs

The headline valor de empresa is the starting point. The actual valor del patrimonio paid to el vendedor is determined by precio de compra adjustment mechanisms. These mechanisms allocate economic risk between signing and cierre, and they drive some of the most complex negotiations in any deal.

Para los equipos de transaction services, the choice of mechanism shapes the diligence scope, the report deliverables, and the posterior al cierre workstreams.

Completion Accounts

The most common mechanism in North American transactions. The precio de compra is adjusted based on the balance at cierre.

Cómo It Works

1. At signing, the parties agree on valor de empresa and target levels for net debt, working capital, and sometimes other balance items.
2. At cierre, el comprador pays an estimated precio de compra based on preliminary estimates.
3. Within 60 to 90 days after cierre, el comprador prepares completion accounts measuring actual net debt and working capital at cierre.
4. The difference between actual and estimated amounts adjusts the precio de compra. Overpayments are refunded. Underpayments are topped up.

Diligence Implications

The transaction services team must deliver:

• A clear net working capital analysis establishing el objetivo working capital level
• A comprehensive net debt bridge identifying all debt-like items
• Accounting policy analysis to establish the basis of preparation for completion accounts
• Sensitivity analysis showing the range of potential adjustments

El equipo de due diligence also defines the accounting policies that govern the completion accounts. These policies determine how every balance item is measured at cierre. Ambiguous policies create posterior al cierre disputes.

Advantages and Risks

For buyers: Protection against balance deterioration between signing and cierre. El comprador pays for what it receives at cierre.

For sellers: Risk that el comprador will interpret completion accounts aggressively to reduce the final price. The dispute resolution process can extend final settlement by months.

Locked Box

Common in European and auction transactions. The precio de compra is fixed based on a historical balance date.

Cómo It Works

1. The parties agree on an valor del patrimonio based on a reference balance at the locked-box date (typically the most recent audited or interim balance).
2. Between the locked-box date and cierre, el vendedor is prohibited from extracting value from el objetivo (no dividends, management fees, or non-arm's-length transactions). These are called "leakage" provisions.
3. El comprador may compensate el vendedor for the period between the locked-box date and cierre through a daily interest accrual or value uplift.
4. No posterior al cierre precio de compra adjustment. The price is final at cierre.

Diligence Implications

El equipo de due diligence must:

• Analyze the locked-box balance in detail, since it determines the final price
• Define and monitor permitted and prohibited leakage categories
• Assess the adequacy of the daily interest or value uplift mechanism
• Review audit trail documentation for all transactions between the locked-box date and cierre

The quality of the locked-box balance is critical. Unlike completion accounts, there is no posterior al cierre true-up. Any errors in the reference balance flow directly to el comprador.

Advantages and Risks

For sellers: Price certainty. No posterior al cierre disputes over balance measurement.

For buyers: Risk that the business deteriorates between the locked-box date and cierre. Limited recourse if the locked-box balance contains errors.

Earn-Outs

A portion of the precio de compra is contingent on posterior al cierre performance. Used when buyer and seller disagree on value or when el vendedor's continued involvement is critical.

Cómo It Works

1. A portion of the precio de compra (typically 10% to 30%) is contingent on el objetivo achieving specified financial or operational milestones after cierre.
2. Milestones are typically revenue, EBITDA, or customer metrics measured over one to three years.
3. Payment is made after each measurement period if the milestones are achieved.

Diligence Implications

The transaction services team should:

• Assess the achievability of earn-out targets against historical performance and market conditions
• Review the proposed measurement methodology for manipulation risk
• Analyze the interaction between earn-out metrics and EBITDA adjustments
• Advise on accounting policy provisions that prevent el comprador from undermining earn-out achievement

Earn-out disputes are among the most common sources of posterior al cierre litigation. Clear definitions, detailed measurement methodologies, and independent verification reduce this risk.

Advantages and Risks

For sellers: Opportunity to realize full value if the business performs. Bridge the valuation gap.

For buyers: Downside protection if the business underperforms. Alignment of seller incentives during transition.

For both: Earn-outs are complex to negotiate, difficult to administer, and frequently disputed.

Choosing the Right Mechanism

The choice depends on dinámica de operaciones:

Many deals combine mechanisms. A locked-box deal may include a small earn-out for specific growth targets. A completion accounts deal may include an earn-out for retention of key customers.

El Transaction Services Role

Regardless of mechanism, the transaction services team shapes the outcome by defining accounting policies, establishing targets, and producing the analysis that supports price negotiations. Teams that maintain standardized deal workflows across their practice handle these complex mechanisms more efficiently and with fewer errors.
