W&I Insurance vs Escrow: How Buyers and Sellers Protect a Deal

In a purchase agreement the seller gives warranties (called representations and warranties in US practice): statements of fact about the business, such as "the accounts are accurate", "there is no litigation", "the company owns its software". If a warranty is untrue, the buyer may be able to claim for its loss. Separately, the seller may give indemnities: promises to pay pound-for-pound or dollar-for-dollar for specific identified risks, such as a known tax exposure.

A warranty is only worth what can be recovered under it. Once the seller has been paid and the proceeds have been spent, invested or distributed, chasing a claim can be slow and uncertain. Protection mechanisms exist to make recovery practical. The purchase agreement sets the rules around them: caps, time limits, minimum claim sizes and what the seller has disclosed.

At completion, part of the price is paid into an account controlled by an escrow agent, usually a bank or specialist provider. An escrow agreement signed by buyer, seller and agent sets out when money is released: on a set date, on joint written instructions, or on a court or tribunal decision. If the buyer brings a valid claim before the release date, the disputed amount stays in escrow until resolved.

• StrengthThe money exists and is held by a neutral party. Neither side has to trust the other to pay.
• WeaknessThe seller does not have use of the money, and recovery is usually capped at the escrowed amount unless the purchase agreement says otherwise.
• Watch forStaged releases, interest on the escrowed funds, who pays the agent, and the exact wording of release instructions.

Holdbacks and deferred consideration

A holdback works like escrow, but the buyer keeps the money and pays it later. It is cheaper and simpler, but the seller carries the buyer's credit risk and must trust the set-off rules. Seller notes and deferred payments can carry similar set-off rights; our guide to seller financing covers how sellers protect themselves when part of the price is paid later.

In the most common form, a buy-side policy, the buyer takes out insurance that pays for loss caused by breach of the seller's warranties. Underwriters review the diligence reports and the draft purchase agreement, hold an underwriting call with the buyer's advisers, then issue terms. The buyer chooses a policy limit (the most the policy will pay) and accepts a retention (the first slice of loss the policy does not pay, similar to an excess or deductible).

Because the insurer stands behind the warranties, the seller can often agree a much lower cap on its own liability, sometimes nominal, except for fraud. That is why sellers, and private equity sellers in particular, frequently ask for insurance-backed deals: it lets them distribute proceeds without a long tail of potential claims.

• Buy-side policyThe buyer is the insured. Most common, because the buyer can claim directly and the seller can be released.
• Sell-side policyThe seller is insured against claims the buyer brings. Less common; the buyer still claims against the seller.
• Knowledge scrape and materiality scrapePurchase agreement terms that affect how breaches are measured; insurers review how these interact with the policy.
• Synthetic or enhanced coverSome insurers will cover warranties wider than those the seller actually gives, at extra cost. Availability varies.

A policy covers unknown problems. It is not designed for risks already identified. Common exclusions, which vary by insurer, jurisdiction and deal, include:

• Matters the buyer's deal team actually knew about before signing or completion, including issues found in diligence
• Forward-looking statements, forecasts and projections
• Purchase price adjustments such as working-capital true-ups
• Areas the diligence did not cover adequately, as judged by the underwriter
• Specific deal or sector exclusions, for example certain pension, environmental, product liability or cyber exposures
• Fines and penalties that cannot lawfully be insured
• Losses caused by the buyer's own fraud; seller fraud is usually covered for the buyer, with the insurer able to pursue the fraudulent seller

Combinations are common. A frequent structure is a buy-side policy covering general warranties, a small escrow that sits under the retention, and a specific indemnity with its own escrow for one known issue. The more these layers interact, the more important it is that the purchase agreement, policy and escrow agreement use consistent definitions.

1. 01Early in exclusivityBroker approaches insurers with a summary; non-binding indications come back.
2. 02Mid-diligenceChosen insurer receives diligence reports and the draft agreement, then holds the underwriting call.
3. 03SigningPolicy is usually bound at signing, with a no-claims declaration from the deal team.
4. 04CompletionA second declaration covers the gap between signing and completion where relevant.
5. 05EscrowThe escrow agent's onboarding and know-your-customer checks can take time; start early.
