What is M&A Insurance?

M&A insurance typically protects insureds against transactional risk, by transferring certain risks arising out of a deal from the transaction parties to the insurer. The use of insurance capital provides a credible, secure and cost-effective alternative to the more traditional means of addressing and balancing transaction risks, such as price adjustments, escrows, retentions and parental/bank guarantees.

In particular, M&A insurance enables:

  • sellers to secure a clean exit with no overhanging liabilities
  • proceeds of sale to be distributed immediately to shareholders/investors
  • buyers to enhance the competitiveness of their bids by reducing or eliminating holdbacks

Key Products

  • Warranty & Indemnity Insurance
    Covers any unknown and unforeseen loss arising from breaches of the warranties provided under an acquisition agreement.
  • Contingent Risk Insurance
    Covers known and quantifiable loss arising out of specific (low risk) issues identified during a transaction diligence process.
