Warranties and Indemnities Insurance

Insurance for managing risk in M&A transactions

Warranties and Indemnities (W&I) Insurance is commonly used in mergers and acquisitions to transfer certain transaction-related risks to an insurer. Policies are structured to address financial losses arising from breaches of representations, warranties, and specified indemnities set out in the sale and purchase agreement.

W&I insurance may be arranged for buyers or sellers and is often used to support transaction negotiations by clarifying post-completion risk allocation, subject to policy terms and conditions.

What Is Warranties and Indemnities Insurance?

Warranties and Indemnities (W&I) Insurance is a form of transaction liability insurance used in mergers and acquisitions. It is designed to cover certain financial losses that may arise from breaches of representations, warranties, or specified indemnities set out in a sale and purchase agreement.

In a typical M&A transaction, sellers are responsible for liabilities relating to the period in which they owned the business. If issues relating to those liabilities are identified after completion and result in financial loss, responsibility would normally rest with the seller, subject to the terms of the transaction.

A W&I insurance policy can be arranged to transfer some of this risk from the buyer or seller to an insurer. The policy responds in line with its terms and conditions where a covered breach of warranty, representation, or indemnity results in a financial loss.

W&I insurance does not replace the underlying transaction documentation. Instead, it operates alongside the sale and purchase agreement, responding to covered claims in accordance with the policy wording and agreed exclusions.

How W&I Insurance Works in an M&A Transaction

In a mergers and acquisitions transaction, the sale and purchase agreement sets out representations, warranties and, in some cases, specific indemnities relating to the target business. These provisions allocate risk between the buyer and the seller in respect of matters such as financial position, compliance, taxation and operations.

Under a Warranties and Indemnities (W&I) insurance policy, the insurer agrees to cover certain financial losses arising from breaches of those representations, warranties or specified indemnities, subject to the policy wording, limits and exclusions.

The policy operates alongside the transaction documentation. If a covered breach is identified after completion and results in a financial loss, the insured party may be able to make a claim against the insurance policy rather than pursuing recovery directly from the counterparty to the transaction.

W&I insurance can be structured for either the buyer or the seller. Buyer-side policies are more common and are designed to respond to losses suffered by the buyer, while seller-side policies may be used to limit ongoing exposure following completion, subject to insurer terms.

The availability and scope of cover will depend on factors such as the nature of the transaction, the due diligence undertaken, the warranties provided, and the insurer’s underwriting assessment.

Who Can Arrange W&I Insurance (Buyers and Sellers)

Warranties and Indemnities (W&I) Insurance can be arranged by either the buyer or the seller in an M&A transaction, depending on how the parties choose to allocate risk and structure the deal.

Buyer-side W&I insurance is the more common approach. Under a buyer-side policy, the buyer is the insured party and may be able to claim under the policy for covered financial losses arising from breaches of warranties or representations given by the seller, subject to the policy terms, conditions and exclusions.

Seller-side W&I insurance may also be arranged in certain circumstances. In this case, the seller is the insured party and the policy is designed to respond to claims brought by the buyer, potentially limiting the seller’s ongoing exposure following completion, subject to insurer approval.

The choice between buyer-side and seller-side W&I insurance will depend on a range of factors, including the transaction structure, negotiation dynamics, and insurer underwriting considerations.

What Is Typically Covered and Excluded

The scope of cover provided by a Warranties and Indemnities (W&I) Insurance policy will depend on the specific transaction, the warranties and indemnities included in the sale and purchase agreement, the due diligence undertaken, and the insurer’s underwriting assessment.

Subject to the policy wording, W&I insurance may respond to certain financial losses arising from breaches of representations, warranties, or specified indemnities given in connection with an M&A transaction.

Cover may include losses relating to areas such as:

  • Financial statements and accounts
  • Tax matters (where covered by warranties or specific indemnities)
  • Compliance with laws and regulations
  • Employment-related matters
  • Ownership of shares or assets
  • Contracts and commercial arrangements

W&I insurance policies will also contain exclusions and limitations, which vary depending on the transaction and insurer.

Common exclusions may include:

  • Known issues identified during due diligence
  • Matters disclosed in the transaction documentation
  • Forward-looking statements or projections
  • Certain environmental liabilities
  • Pension underfunding or specific tax risks (unless expressly covered)
  • Fraud or dishonesty by the insured party

W&I insurance does not provide blanket cover for all transaction-related risks. Each policy is negotiated on a deal-by-deal basis, and cover is subject to specific terms, conditions, limits, retentions, and exclusions.

Specialist transaction risks, such as identified tax exposures, may require separate or standalone insurance solutions.

Other Forms of Transaction Liability Insurance

Tax Indemnity Insurance

In addition to Warranties and Indemnities (W&I) Insurance, other forms of transaction liability insurance may be used in M&A transactions to address specific, identified risks.

Tax Indemnity Insurance is designed to cover the financial impact of a known or identified tax exposure that has been identified during the due diligence process or arises from a particular transaction structure. Rather than providing broad transaction cover, tax insurance is typically arranged to address a specific risk or issue.

A tax indemnity policy may be arranged for the benefit of the buyer, the seller, or the target company, depending on the structure of the transaction and the nature of the risk being insured. Cover is subject to insurer underwriting, policy terms, conditions, limits and exclusions.

Tax Indemnity Insurance is often considered where a potential tax exposure could otherwise affect pricing, deal structure, or post-completion negotiations, and where the parties prefer to transfer that specific risk to an insurer rather than rely on contractual indemnities alone.

Tax Indemnity Insurance operates alongside the transaction documentation and does not replace broader W&I insurance. Each policy is negotiated on a case-by-case basis to reflect the specific tax risk being insured.

Policy Limits, Retentions and Policy Terms

Warranties and Indemnities (W&I) Insurance policies are structured with defined policy limits, retentions, and specific terms that determine how and when cover may respond. These elements are agreed as part of the underwriting process and will vary depending on the transaction, risk profile, and insurer appetite.

The policy limit represents the maximum amount payable by the insurer in respect of covered claims under the policy. Limits are generally set by reference to the transaction value and the level of cover sought, subject to insurer underwriting criteria.

A retention (sometimes referred to as a deductible) usually applies, meaning the insured party is responsible for losses up to a specified amount before the policy responds. Depending on the agreed structure, retentions may reduce over time or fall away entirely.

In addition to limits and retentions, W&I insurance policies include specific policy terms, such as policy duration, notification requirements, exclusions, and conditions. These are documented in the policy wording and assessed on a transaction-by-transaction basis.

Policy terms commonly address:

  • The level and application of policy limits
  • The structure and duration of any retention
  • Policy duration for different warranty categories
  • Notification and claims procedures
  • Transaction-specific exclusions and limitations
  • Alignment with the sale and purchase agreement

W&I insurance is a negotiated product, and policy terms will differ between transactions. All cover is subject to insurer underwriting and the terms and conditions set out in the policy wording.

Claims under W&I and Tax Indemnity Insurance

Claims under Warranties and Indemnities (W&I) Insurance and Tax Indemnity Insurance are handled in accordance with the policy wording and agreed notification procedures. If a potential breach or insured tax issue is identified, the insured party is required to notify the insurer within the timescales set out in the policy.

The insurer will assess the claim based on the policy terms, the transaction documentation, and the circumstances giving rise to the alleged loss. Any response to a claim, including whether and to what extent it may be covered, is subject to the policy’s conditions, limits and exclusions.

Our role is to support clients throughout the claims process by assisting with notification, liaising with insurers and relevant advisers, and helping to manage the process in line with the policy requirements.

Policy limits, conditions and exclusions apply. Please refer to the policy wording for full terms and conditions.
