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 Nationwide?
Nationwide’s commercial catalogue includes common small-business policies and separate specialty products. A catalogue listing does not establish eligibility or policy terms; confirm the issuing company and coverage for your state and business. 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
AIG names varied corporate property customers; Nationwide offers commercial property through its agent and quote route.
AIG cites hospitals, universities, and global manufacturers among organizations with property options. Nationwide describes commercial property for businesses, with occupancy and terms subject to underwriting, and directs buyers to an agent or quote request. The examples give buyers a starting point but do not establish a particular building’s eligibility. Ask both providers to confirm that the property type, location, and operations fit the proposed program. 3 7
AIG names varied corporate property customers; Nationwide offers commercial property through its agent and quote route.
AIG describes physical property and contents exposed to events such as storm damage, theft, and vandalism; issued policy terms determine protection. Nationwide’s page similarly presents commercial property as a product but does not establish coverage or binding from the agent-contact path. Compare the actual building, business personal property, interruption coverage, deductibles, and catastrophe wording in the quotes rather than relying on each overview. 3 7
