W&I Insurance in Company Acquisitions: When the Warranty Policy Pays Off

What W&I insurance may cover

The policy covers contractually defined loss arising from an inaccurate warranty or selected tax obligations under the SPA. Typical areas include:

Cover commonly starts with fundamental warranties on existence, title and authority. Financial warranties on the accounts and management information and warranties concerning material contracts, assets and financing are then included.

Depending on the business, the policy may address IP, IT, cyber and data protection, employees and pensions, permits and compliance and environmental matters, product liability, insurance and litigation. Tax exposure may be covered through the general tax provisions or separate tax cover. In every case, the relevant area needs to have been reviewed adequately and the policy must track the contractual warranty.

The policy does not automatically mirror every word of the SPA. It has its own definitions, exclusions, limits and procedure. A coverage spreadsheet or similar comparison is therefore used to identify differences.

The general subject of W&I is unknown warranty risk. Relevant knowledge is defined in the policy. It commonly means actual knowledge of a specified deal team. The mere technical availability of a document in the data room does not necessarily equal knowledge in every wording. Areas not reviewed adequately or identified as problematic may nevertheless be excluded.

What is commonly excluded or restricted

Typical exclusions include:

The principal exclusions are warranty breaches known to the defined deal team and matters specifically disclosed in due diligence, the data room or the disclosure process. Identified risks remain for an indemnity, price adjustment, escrow or a specialist contingent-risk policy.

Forward-looking statements, business plans and projections and adjustments under locked-box or closing-accounts mechanics are also normally outside cover. Environmental contamination, certain pension exposure, cyber incidents and tax matters may be insurable only on a limited basis or after specialist review.

Legal and market exclusions also apply, including fraud, deliberate misconduct and matters that cannot lawfully be insured. The exclusion profile is transaction-specific and should be analysed while the SPA remains under negotiation.

An identified risk may be dealt with through a specific indemnity, escrow, price reduction or a separate contingent-risk or tax policy. Additional diligence may make some matters insurable. Other matters remain excluded.

Seller fraud requires separate analysis. Depending on the wording, a buy-side policy may protect an innocent buyer despite deliberate seller misconduct, while preserving the insurer's recourse against the responsible persons.

Cost, limit and retention

Premium and terms are transaction-specific. Key factors include deal size, selected limit, jurisdictions, industry, diligence quality, warranty breadth, policy period, retention and competitive tension among insurers.

The premium is normally a one-off percentage of the insured limit rather than the entire purchase price. Broker remuneration, underwriting fees and insurance premium tax may apply in addition.

The limit follows the negotiated liability profile and need not equal the purchase price. Fundamental warranties may receive a higher limit or specific enhancements.

Retention may be a fixed amount, a percentage of enterprise value or a tipping arrangement. Some transactions can obtain nil or very low retention. The SPA's de minimis and basket need to be coordinated with the policy.

Instead of relying on generic market percentages, the parties should obtain early non-binding indications. These show the available premium, retention, exclusions, policy periods and enhancements for the actual transaction.

The process within the SPA

W&I placement runs in parallel with diligence and SPA negotiation.

The broker first prepares a briefing from the initial transaction information and obtains non-binding indications from a number of insurers. Once a preferred insurer is selected, it receives access to the data room, draft SPA and due-diligence reports and begins its underwriting review.

Open points are discussed with the buyer and advisers during the underwriting call. The outcome feeds into the warranty spreadsheet, exclusions and policy. At the same time, the SPA and insurance wording need to be aligned so that definitions, liability standard and claim mechanics work together.

The policy is commonly bound at signing. A bring-down process may be required between signing and closing to address new information and developments. Premium, insurance tax and underwriting fee are paid through the agreed funds flow, and cover attaches in accordance with the policy.

The process works best if started before diligence is complete. Early involvement allows the review scope and SPA to be shaped so that avoidable coverage gaps do not arise.

Cross-border: why foreign buyers almost always require W&I

For buyers from abroad, the policy solves several problems at once. It removes the risk of having to pursue a German seller for years after closing and of enforcing a judgment across borders. It protects the future business relationship where the seller stays on board as managing director or minority shareholder, because claims run against the insurer instead of the individual. At the same time, it allows the seller a clean exit without escrow arrangements, which is an advantage in a competitive bidding process. In international auction processes, the insured structure is therefore often already prescribed in the process letter.

Legal and contractual framework

The SPA and policy are separate contracts. The SPA defines the seller's obligation. The policy determines the insurer's cover.

Key points to align include:

The insured warranty breach, loss definition and disclosure standard must first match between the SPA and the policy. The same applies to knowledge, any materiality scrape, remedies and the treatment of price reduction or multiple-based damages.

Retention, de minimis, basket, policy limit and claim periods need to be reconciled with residual seller liability. Tax, fundamental warranties and identified risks may require different limits or specialist cover.

The claims process also needs clear notice, cooperation and defence provisions. Buyer, seller and insurer should understand who controls third-party claims, which settlements require consent and how recovery from other responsible parties is treated.

In a typical buy-side structure, seller exposure for business warranties may be nominal or limited, while fundamental warranties, covenants, purchase-price obligations and fraud are treated separately. The policy must not inadvertently conflict with this allocation.

Known risks remain outside general W&I cover and require a bespoke SPA solution or specialist insurance. W&I is part of the contract architecture, not a replacement for it.
