Buying a business is rarely just about agreeing the price. Once the commercial terms have been settled, attention often turns to a more difficult question: who carries the risk if something comes to light after completion that nobody expected?
That question can become one of the biggest sticking points in an acquisition. A buyer wants confidence that the information used to value the business is accurate. A seller wants to complete the transaction without wondering if part of the sale proceeds could be claimed back months or even years later.
Warranty and indemnity insurance, often referred to as W&I insurance, exists to help bridge that gap. Rather than leaving every potential warranty claim solely between buyer and seller, it allows certain risks to be transferred to an insurer. Used alongside thorough due diligence and a carefully drafted sale agreement, it can help both parties complete a transaction with greater confidence.
Why risk allocation matters
Every acquisition involves an element of uncertainty.
Even the most detailed financial, legal and commercial due diligence cannot guarantee that every issue has been identified before completion. Businesses have long trading histories, complex contracts, employment obligations, tax considerations and regulatory responsibilities. Sometimes information only comes to light after ownership has changed hands.
That is why warranties are included within a sale and purchase agreement. They provide contractual assurances about matters such as the company’s accounts, assets, contracts, employees, intellectual property and compliance. If one of those warranties proves to be inaccurate and the buyer suffers a financial loss, there may be grounds to bring a claim.
The challenge is deciding who should carry that risk.
Where negotiations often become difficult
Most acquisitions reach a stage where the discussion moves beyond the purchase price.
A buyer may want broad warranty protection and meaningful recourse if something unexpected emerges after completion. A seller is more likely to want certainty that the proceeds of the sale can be retained without facing years of ongoing exposure.
Without insurance, that difference in approach can lead to lengthy negotiations around liability caps, escrow accounts, retention amounts and warranty periods. None of those mechanisms are unusual, but they can slow progress and make it harder for both parties to reach an agreement.
Warranty insurance offers another option by providing an additional source of financial protection for covered losses.
Why buyers often see value in W&I insurance
From a buyer’s perspective, the attraction is not simply having an insurance policy. It is knowing there may be another route to recover losses if a covered warranty breach is discovered after completion.
That can be particularly helpful when the seller is made up of individual shareholders, where sale proceeds are likely to be distributed soon after completion, or where the seller’s future financial position may be uncertain.
In other cases, the transaction may involve overseas sellers, private equity investors or businesses operating in sectors where historic liabilities can take time to emerge. Insurance can provide reassurance without requiring the seller to retain a significant proportion of the purchase price indefinitely.
It does not mean every issue will be covered. Insurers will review the transaction carefully and will only insure risks that fall within the agreed policy terms.
Why sellers choose to use it
For sellers, W&I insurance is often about achieving a cleaner exit.
Selling a business is frequently the result of years of investment and planning. Owners may be retiring, moving on to another venture or distributing the proceeds between several shareholders. Few want to leave a substantial amount of money tied up against potential future claims if there is another way to manage the risk.
Insurance can sometimes help reduce the level of liability a seller is expected to retain, allowing negotiations to move forward without leaving the seller exposed long after ownership has transferred.
Fraud and other specifically excluded matters will still remain the seller’s responsibility, but insurance can help narrow the areas of disagreement during negotiations.
Insurance works best alongside good due diligence
One of the biggest misconceptions about W&I insurance is that it replaces due diligence.
In reality, the opposite is true.
Insurers expect buyers and their advisers to carry out detailed financial, legal, tax and commercial investigations before cover is offered. The quality of that work plays a significant role in the underwriting process.
If important areas have not been investigated properly, insurers may exclude those risks from the policy or decline to provide cover altogether.
Good due diligence does not make insurance unnecessary. Instead, it gives insurers greater confidence about the risks they are being asked to accept.
Timing can make a difference
Businesses sometimes leave discussions about insurance until the transaction is approaching completion.
That can limit the options available.
Considering W&I insurance earlier allows buyers, sellers, legal advisers, accountants and corporate finance teams to understand how the cover could support the structure of the deal before negotiations become fixed.
It also gives time to review different insurers, compare policy terms and understand exactly what is covered, rather than treating insurance as a last-minute addition.
Understanding what the policy is designed to do
Like any commercial insurance policy, W&I insurance has defined terms, conditions and exclusions.
It is designed to respond to certain unknown warranty breaches that result in financial loss. It is not intended to insure risks that are already known, issues identified during due diligence or matters that fall outside the agreed policy wording.
Understanding those distinctions is just as important as arranging the cover itself.
An experienced insurance broker can help businesses assess whether W&I insurance is appropriate for the transaction, explain how different policies compare and work alongside legal advisers throughout the process.
Supporting successful transactions
Every acquisition is different, and there is no single approach that suits every deal.
For some transactions, warranty insurance may help bridge the gap between buyer and seller, allowing negotiations to progress more smoothly. In others, the nature of the business or the risks involved may mean alternative solutions are more appropriate.
The important point is that insurance should be considered as part of the wider transaction strategy rather than as a product to arrange once everything else has been agreed.
When introduced at the right stage and supported by thorough due diligence, warranty and indemnity insurance can help buyers and sellers complete acquisitions with greater confidence while ensuring risk is allocated in a way that reflects the commercial objectives of everyone involved.
