Asset and Liability Guarantee (GAP): Secure your 2026 Transfer

Updated March 2026 - In the context of a business sale (shares or shares), the Guarantee of Assets and Liabilities (GAP) is undoubtedly the most fiercely negotiated clause. A true shield for the buyer and a straitjacket for the seller, it defines who bears the risks linked to the company's past. In 2026, with the rise of cyber and ESG risks, GAPs will be enriched with new themes.

The principle is simple: the seller guarantees the buyer that the accounting situation established at the time of the sale is accurate.

• ▸Liability Guarantee: The seller undertakes to compensate the buyer if a liability whose origin predates the transfer is revealed afterwards (e.g. a tax adjustment for the year N-1).
• ▸Asset Guarantee: The seller guarantees the value of the assets (e.g. a customer debt which turns out to be irrecoverable).

The negotiation generally focuses on four pillars: the duration, the ceiling, the threshold and the guarantee of the guarantee.

1. The Duration (Survival Period)

The seller is not responsible forever. The duration of the GAP is limited.

• ▸Common law: Generally 12 to 24 months for operational risks.
• ▸Specific areas: It is often aligned with the legal limitation periods (3 years for fiscal and social matters, 5 years for environmental matters).

2. The Ceiling (Cap)

This is the maximum amount that the seller will be required to pay in the event of the warranty being called into play. It is often expressed as a percentage of the sale price (between 10% and 30%).

3. The Trigger Threshold (Basketball)

To avoid disputes over trivial sums (e.g. a forgotten parking fine), we define a threshold.

• ▸Deductible: Compensation begins beyond the threshold for the excess portion.
• ▸Trigger threshold at 1st euro: As soon as the threshold is exceeded, the entire damage (including the threshold) is due.

4. The Guarantee of the Guarantee

How can you be sure that the seller will be able to pay in 2 years? We often set up an escrow account (Escrow) or a bank guarantee. In 2026, W&I (Warranty & Indemnity) insurance becomes more widespread for medium-sized transactions, making it possible to transfer the risk to an insurer.

The classic GAP is evolving. Today, we systematically integrate:

• ▸Cyber Clauses: Guarantee against undeclared security breaches or historical GDPR non-compliance.
• ▸ESG clauses: Responsibility of the seller in the event of hidden environmental liabilities (soil pollution) or serious breach of social standards (hidden work with a subcontractor).

Hayot Expertise Advice: Never sign a GAP without a prior audit (Due Diligence). It is this audit that allows the seller to “disclose” known risks and exclude them from the warranty. Disclosed information is guaranteed information!

If the buyer discovers a problem (e.g. notification of adjustment), he must inform the seller within a very short period of time (denunciation clause). The seller then has the right to review the defense. If the buyer does not respect this formality, he may lose his rights to compensation.

As architects of the transaction, we intervene at two levels:

1. ▸Seller's side: To limit the scope of the guarantee by precisely listing the liabilities already provisioned.
2. ▸Acquirer side: To verify that the GAP covers the risk areas identified during the accounting audit.

A GAP that is too protective for the buyer can discourage the seller; a GAP that is too low can prove suicidal for the buyer. The success of a deal in 2026 lies in the surgical precision of these clauses.
