What Is AIG?
AIG is the marketing name for American International Group, Inc.; AIG says its insurance products are written or provided by subsidiaries or affiliates. Its U.S. business pages list commercial casualty, property, cyber, management and professional liability, and specialty programs, but a brand-level page does not identify the insurer for a particular policy. 1,2

What Is Professional Errors and Omissions (E&O) Insurance?
Professional liability can help pay defense costs and covered losses when a client says your advice or service caused financial harm. If customers rely on your work, list every service you provide and check the claims-made reporting and prior-work terms. 11,12,13,14
Key Differences in 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. 3 9
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. 3 4
