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
CNA Small Business Insurance: Products, Agents and Service
CNA directs small-business buyers to independent agents and describes CNA Connect as a businessowners policy for more than 600 small-business classes. Issuer and availability vary by policy and state, so confirm both in a quote. 4,5,6
What Is Commercial Property Insurance?
Commercial property may fit your business if you own a building or rely on equipment and stock. Compare replacement-cost terms, deductibles and any coinsurance condition, and check lost-income protection separately. 8,9,10
Key Differences in Commercial Property Insurance
Industry examples versus named small, midsize, and large tiers
AIG names hospitals, universities, and global manufacturing among its commercial-property audiences but does not publish a complete eligibility schedule. CNA distinguishes Connect for small risks, Paramount for midsize accounts, and Touchstone for large property risks. A buyer can use CNA’s tier labels to ask which underwriting route is intended, while AIG’s public description calls for a broker to confirm whether its broader appetite fits the account. 3 7
CNA placement structures and risk-control services
AIG describes property protection and engineering, while CNA sets out admitted or non-admitted placements and primary, buffer, excess, quota-share, or layered structures. CNA also lists sprinkler review and business-continuity planning by property risk-control professionals. Those program choices affect how coverage sits alongside other layers; ask which structure and risk services appear in the proposal rather than assuming a general capability is attached. 3 7
