Definition:Warranty and indemnity insurance policy (W&I insurance policy)
📄 Warranty and indemnity insurance policy (W&I insurance policy) is the contractual document that sets out the terms, conditions, coverage scope, and exclusions under which an insurer agrees to indemnify the insured party for losses arising from breaches of representations and warranties in an M&A purchase agreement. While the broader concept of W&I insurance describes the product class, the policy itself is the binding legal instrument that governs the relationship between the insured (typically the buyer in a buy-side placement) and the insurer, and its precise wording determines whether a particular claim will be covered.
🔍 The policy is structured around several core components. The insuring clause identifies which warranties from the underlying acquisition agreement are covered and sets the policy limit — often aligned with the seller's indemnity cap in the purchase agreement. A retention (sometimes called an excess or deductible) establishes the threshold of loss the insured must absorb before the insurer pays; this retention may "tip" (meaning the insurer pays from the first dollar once the threshold is breached) or apply as a true deductible. The policy will typically include a schedule of specific exclusions reflecting risks identified during due diligence or deemed uninsurable, along with general exclusions for items such as known breaches, consequential damages beyond the policy's scope, and certain regulatory or tax matters. Duration is another critical element: W&I policies for general warranties commonly run for two to three years from closing, while tax and fundamental warranties often carry longer coverage periods of five to seven years, tracking the warranty survival periods negotiated in the deal itself.
⚖️ Precision in the policy's drafting has direct financial consequences. Because the W&I policy sits as a parallel contract alongside the purchase agreement, any gap between the two documents — in definitions, warranty scope, or notice requirements — can create coverage disputes. Sophisticated buyers and their brokers invest significant effort in aligning the policy wording with the acquisition agreement, negotiating the removal or narrowing of exclusions, and ensuring that the claims notification process is practical. In jurisdictions with well-developed W&I markets, such as the United Kingdom, Germany, and Australia, standardized policy forms and market practices have emerged, providing greater predictability. In newer markets across Southeast Asia and Latin America, policy terms tend to be more bespoke and subject to greater negotiation. For insurers, the policy represents a concentrated underwriting risk tied to a single transaction, making the quality of pre-bind underwriting — the review of due diligence materials, disclosure processes, and deal terms — the primary risk management lever.
