M&A

Warranty and indemnity insurance

Allocate selected breach risk to an insurance policy whose coverage, exclusions, retention, limits and claims process have been reconciled with the acquisition agreement.

Quick answer

Warranty and indemnity insurance is transaction insurance that may cover specified losses arising from breaches of insured representations and warranties, subject to the policy's terms. The policy and acquisition agreement must be reviewed together because exclusions, retention, limits, subrogation, fraud treatment and remedy provisions can change the practical recovery path.

Use the worked example

Meaning and transaction use

An SEC-filed purchase agreement requires a buyer-side W&I policy and describes it as the buyer's sole remedy for specified non-indemnified claims, subject to stated exceptions. [S1]

The same agreement addresses premium payment, compliance with the policy and limits on insurer subrogation against the seller. [S1]

A separate SEC-filed transaction disclosure states that coverage was subject to retention, exclusions, policy limits and other terms. [S2]

Worked example

Illustrative policy bridge only. Assume a covered loss of 3.0 million, a 0.5 million retention and a 2.0 million remaining policy limit, with no additional adjustment in this example.

MeasureCalculationResult
Loss above retention3.0 - 0.52.5m
Remaining policy limitGiven2.0m
Illustrative recoveryLesser of 2.5 and 2.02.0m
Illustrative unrecovered amount3.0 - 2.01.0m

The illustrative recovery is capped at 2.0 million. Actual recovery requires a covered breach, compliance with the policy and application of all terms.
