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

Coverage Subject and Exclusions

AIG describes coverage for allegations of negligence in professional services, including third-party economic loss, with definitions and exclusions controlled by the policy. Coterie lists its E&O coverage and names excluded services and claim types in its reviewed terms. A firm should compare its actual work and client allegations against Coterie’s exclusions and AIG’s proposed services definition before relying on either broad product description. [1] [3]

Published Limit Structure

Coterie publishes per-claim and aggregate limits for its professional-liability product, while AIG’s reviewed record does not give a standard limit. AIG says the policy can be customized to a company’s professional services, so the quote is needed to see its capacity. Buyers should compare the limit basis, retention and whether defense costs reduce the available amount. [1] [3]

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

  • Ask AIG for written limits, retention, excluded services and defense-cost treatment. [1]
  • Ask Coterie to confirm your profession is eligible and that its published limits remain available for your requested terms. [3]
