  • coverage: HUB says professional liability/E&O policies it arranges can cover defense costs, judgments, settlements and fines from allegations of misrepresentation, breach of professional services, wrongful business practices, misleading advice and conflict of interest, plus libel, slander or lost-profit claims; intentional acts and employment claims are typically excluded. Product-page coverage description; the issued policy and its exclusions control an actual claim.company-reportedSource ↗

What Are the Key Differences Between AIG and HUB International Professional Liability (E&O) Insurance?

Policy Scope and Broker Role

AIG describes coverage for allegations of negligent professional services, including third-party economic loss. HUB International acts as a broker and describes arranging professional-liability coverage across client industries. A buyer should compare AIG’s proposed insuring agreement with the policy HUB places, since HUB’s brokerage role does not determine which insurer or wording will be selected. [1] [4]

Structure and Claims Assistance

AIG says in-house claims professionals and outside experts work with policyholders through claims and use claims data for risk evaluation. HUB describes claims assistance alongside professional-liability placement. These services address the path after a loss, while the policy controls coverage; ask who receives notice, who selects defense counsel and whether defense costs reduce limits. [1] [3]

What Should You Confirm in AIG and HUB International Professional Liability (E&O) Insurance Quotes?

  • Ask AIG who will handle claims and whether defense costs erode the quoted limit. [1]
  • Ask HUB which insurer and form it proposes, and what claims assistance is included in the brokerage engagement. [4]

AIG describes entity-based E&O for negligent professional services; HUB International’s brokers tailor placements and claims support across professional-liability exposures.
