Key Differences in Representations and Warranties Insurance
Indemnity design and policy structure
Lockton says RWI can replace or bolster seller indemnity or escrow, with the insurer indemnifying a buyer for loss from an unknown breach in the deal agreement. AIG likewise describes protection against seller-representation breaches, and lists shared, layered, and excess structures. Buyers and sellers negotiating who retains post-close exposure should compare Lockton's stated indemnity use with the exact layer and allocation AIG would quote. 7 3
Claims expertise
Lockton says dedicated transaction-liability claims experts support clients after binding and reports having helped settle hundreds of millions of dollars of RWI claims. AIG describes dedicated claims professionals for complex transactional disputes alongside M&A underwriting support. Both records therefore name claims resources; ask each team how those specialists participate in a claim and which insurer makes coverage decisions. 7 3
