What Is Representations and Warranties Insurance?
Representations and warranties insurance can cover a buyer’s or seller’s loss from inaccurate statements in a stock or asset purchase agreement. For a business sale, check who is insured, who can recover and how known issues are treated. 9,10,11
Key Differences in Representations and Warranties Insurance
Buyer or Seller Objectives
AIG says its product can protect buyers or sellers against financial loss from breaches of seller representations and warranties and offers shared, layered and excess structures. Chubb describes buyer-side protection beyond negotiated caps and survival limits, including seller collectability risk, while its seller-side policy backstops indemnity obligations and may address joint-liability concerns. Parties should select the policyholder’s objective before comparing retention and exclusions. 3 7
Transaction Placement
AIG markets transaction-specific cover written through non-admitted carriers and describes dedicated M&A underwriters and claims professionals. Chubb underwrites R&W directly through its transactional-risk team, working with buyer, seller and their brokers. The practical distinction is whether the deal team engages the insurer or arranges a placement through AIG’s product structure; confirm the issuing entity and who handles diligence. 3 7
