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

Policy Design and Covered Acts

AIG describes E&O intended for allegations of negligent professional services, including third-party financial loss. Counterpart separates professional-liability products by professional acts and distributes them through broker relationships. That segmentation may matter when a business performs several distinct services: buyers should identify which acts each policy covers and whether Counterpart requires separate products, then compare both definitions and exclusions. [1] [6]

How the Policy Is Reached

AIG markets a customizable entity-based offering; Counterpart’s record describes broker distribution. Neither label identifies the quote-specific insurer or all placement terms. A buyer should establish who will negotiate the placement, which insurer will issue it and who will handle questions after binding before comparing the two routes. [1] [5]

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

  • Ask AIG which services and financial-loss allegations are covered and who issues the policy. [1]
  • Ask the Counterpart broker which professional acts and policy modules match your work, and identify the issuing insurer. [6]
