AIG vs WTW: How Do They Compare for Professional Liability (E&O) Insurance?

AIG markets customizable entity-based professional errors-and-omissions policies for public and private service providers.

AIG’s U.S. Professional Liability page. The page describes the marketed product family, not the legal insurer on an individual quote or policy.

Under WTW's North American Corporate Risk & Broking terms, WTW normally acts as the client's insurance intermediary for engagements governed by those terms. ⁹Company-reported. Terms for applicable North American Corporate Risk & Broking engagements. WTW also discloses separate insurer-side services in some arrangements; this does not determine the role in a specific engagement.

The reviewed WTW sources do not identify an issuing insurer for a specific professional errors omissions placement. ^9,8,7Not publicly disclosed.

WTW's FY2024 annual report describes professional-liability solutions within FINEX; its residential practice lists errors-and-omissions among financial lines for residential real-estate stakeholders. ^8,7Company-reported.
