How we support

Your business performs
For many sellers, an M&A transaction represents the culmination of years of work. W&I Insurance can help unlock deal proceeds faster by reducing the need for sellers to stand behind warranties and tax indemnities for an extended period after completion. For buyers, it provides comfort that a regulated insurer is standing behind the agreed policy.
How does Warranty & Indemnity Insurance work?
Fundamentally, W&I insurance is designed to free up deal proceeds faster than in an uninsured deal.
Without insurance, sellers must stand behind the warranties and tax indemnities that they give in the sale agreement. This liability can be significant (the cap on liability can be the full purchase price, and the survival period up to 7 years from completion of the deal).
W&I Insurance is designed to transfer the liability for a warranty claim to an insurer and is typically arranged during the transaction process and paid for through a one-off premium at completion. In most cases, the buyer becomes the policyholder. If a covered warranty claim arises, the buyer deals directly with the insurer rather than pursuing the seller, helping the seller achieve a clean exit and giving the buyer the reassurance of a carefully drafted policy.
Without W&I Insurance, sellers may remain liable for warranty and tax indemnity claims after completion. That liability can be significant, with caps potentially linked to the full purchase price and survival periods lasting several years. W&I Insurance is designed to transfer the risk of a warranty claim to an insurer, supporting cleaner exits for sellers and greater protection for buyers.
