In the legal documentation formalizing an M&A transaction, agreements are typically made regarding who bears the risk of ‘hidden defects’ that may come to light after the transaction date. These agreements often take the form of warranties and tax indemnities provided by the seller to the buyer. If a breach of these warranties or indemnities occurs post-transaction, the seller is generally liable for compensating the buyer’s damages. The specific ‘rules’ governing such claims are usually detailed in the transaction documentation.
However, negotiating these ‘rules’ in a way that is acceptable to both parties is legally complex and often involves extensive discussions between the attorneys involved. The parties may have differences in approach to these ‘rules.’ For example, the seller may seek to exclude or further limit their liability for claims related to ‘hidden defects’ beyond what the buyer find acceptable. Alternatively, the seller may be unwilling to provide the level or form of security that the buyer requires.
In such situations, it may be advisable to consider taking out warranty & indemnity insurance (W&I insurance). W&I insurance is a specialized insurance product designed to transfer the financial risks of a breach of warranties or tax indemnities provided by the seller to the buyer after the transaction date to an insurer - meaning the insurer, rather than the seller, compensates the buyer’s losses.
Although sellers can also take out W&I insurance, in Dutch small and mid-market M&A transactions, it is almost always buyers who purchases this coverage. This article, therefore, focuses on W&I insurance from the buyer’s perspective.
Whether W&I insurance is advisable depends on several factors, which we will explore in the next section.
Time pressure
If there is pressure to close the transaction quickly, W&I insurance can help accelerate the process. With W&I insurance in place, fewer negotiations are needed regarding the warranties and security the seller must provide to the buyer. Since the financial risks of warranty breaches are transferred to the insurer, the seller can take a more flexible stance on warranties, and the need for seller-provided security becomes less relevant or even irrelevant.
However, this comes with the caveat that an insurer will only issue a W&I policy for risks that have been thoroughly assessed through comprehensive due diligence by the buyer. This aligns with the insurance industry’s fundamental principle that “a burning house cannot be insured.” To obtain broad coverage under a W&I policy, a comprehensive due diligence process - conducted by experienced external advisors - is essential. If the parties opt for a limited or ‘practical’ due diligence process, or if the buyer intends to conduct part of the due diligence internally, W&I insurance will likely not be an option.
It is also important to note that a comprehensive due diligence process is not only an additional burden for the buyer but also for the seller. After all, the seller must provide the necessary information for the comprehensive due diligence, and the additional time and effort required should not be underestimated, especially since, in addition to facilitating the due diligence process, the seller remains responsible for managing the day-to-day operations of the target company
Costs
The W&I insurance market has become increasingly competitive in recent years. As a result, W&I insurance premiums are relatively modest compared to the transaction value. The premium is calculated as a percentage of the insured amount, which typically ranges between 10% and 30% of the enterprise value. In general, premiums are approximately 1% to 1.5% of the insured amount. For example, if the enterprise value is €40 million and the insured amount is €10 million, the premium would range from €100,000 to €150,000.
