How Representations and Warranties Insurance Works in Middle Market M&A

When a business sale closes, the seller wants to walk away clean. The buyer wants protection if something turns out to be wrong. Representations and warranties insurance exists to bridge that gap — and in middle market M&A, it has moved from a niche tool to a standard deal feature.

Understanding how R&W insurance works, when it makes sense, and what it does not cover is essential for any founder preparing to sell.

What Is Representations and Warranties Insurance?

Representations and warranties insurance is a policy that covers financial losses arising from breaches of the seller’s representations and warranties in a purchase agreement. If a buyer discovers post-closing that a representation was inaccurate — say, that the seller’s financial statements overstated revenue, that a key contract had an undisclosed termination right, or that IP ownership was not as clean as represented — R&W insurance pays the claim rather than requiring the buyer to pursue the seller directly.

The policy is most commonly structured as a buy-side policy, meaning the buyer is the insured. This has become the market standard because it removes the seller from post-closing liability and allows them to distribute sale proceeds without maintaining a large escrow holdback.

Why R&W Insurance Has Become Standard in Middle Market Deals

A decade ago, R&W insurance was primarily used in large transactions. Minimum premiums made it economically impractical for smaller deals. That has changed significantly. Policies are now available for deals as small as $20 million, and the product has become routine in transactions ranging from $30 million to $250 million.

The shift has been driven by both sides of the table. Sellers in competitive processes use R&W insurance to offer buyers stronger protection without tying up proceeds in escrow for years. Private equity buyers have embraced it as a clean way to manage post-closing risk across multiple portfolio acquisitions. Strategic buyers use it to preserve the relationship with the seller management team, particularly in deals where the seller is staying on post-close.

How the Policy Works

The buyer purchases the policy before closing, typically with the cost shared or negotiated between buyer and seller as part of deal economics. The policy attaches at a retention — a deductible the buyer must absorb before the insurance responds — which is typically set at 1% of the transaction value. Coverage then responds up to a policy limit, which in most middle market deals is set at 10% to 15% of enterprise value.

The insurer underwrites the policy based on a review of the due diligence conducted in the transaction. The buyer’s legal and financial diligence forms the basis of the insurer’s comfort. Known issues identified during diligence are typically excluded from coverage — the policy is designed to cover unknown breaches, not problems the buyer already discovered and accepted.

Claims are made against the policy directly. The seller is not involved unless fraud is established, which most R&W policies explicitly preserve as a carve-out from seller protection.

What R&W Insurance Does Not Cover

R&W insurance is not a substitute for thorough due diligence, and it does not cover everything. Standard exclusions include known breaches — anything identified in diligence or disclosed in the schedules to the purchase agreement. Purchase price adjustments, such as working capital true-ups, are also excluded. Forward-looking representations about future performance are not covered. Environmental liabilities, pension obligations, and certain tax matters often require separate treatment or specific endorsements.

Sellers and buyers who assume R&W insurance covers the full range of post-closing exposure are routinely surprised by what falls outside the policy. The exclusions are negotiated at the time of underwriting and should be reviewed carefully by counsel before closing.

What Sellers and Buyers Should Know Before the Deal

For sellers, R&W insurance changes the negotiation around escrow. In a deal without R&W insurance, buyers typically require 10% to 15% of the purchase price held in escrow for 12 to 24 months as security against representation breaches. With a buy-side R&W policy in place, escrow requirements drop significantly — often to 0.5% to 1% of deal value, held for a shorter period and limited to specific carve-outs like fraud or fundamental representations.

For buyers, R&W insurance is a due diligence discipline. Insurers require that diligence be thorough enough to support the representations being insured. A buyer who cuts corners on diligence may find that the insurer denies coverage on the basis that the issue was knowable. The policy is only as strong as the process behind it.
