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
Markel Insurance: Specialty Business and Products
Markel Insurance is Markel Group's specialty and small-business insurance business, with offerings across packages, workers' compensation, cyber, professional and management liability, property, marine, and surety. Products use different insurers and distribution routes, so compare the issuer and terms shown on the specific quote. 4,5
What Is Inland Marine Insurance?
If your business moves equipment between sites or ships goods, inland marine can cover those property exposures; installation and other forms address different property categories. Match the quote to what you own, rent or hold for others. 7,8
Key Differences in Inland Marine Insurance
Industry breadth and tailored exposure types
AIG’s product overview emphasizes transportation/logistics and construction/equipment, including contractor and movable-property exposures. Markel lists inland-marine products across construction, transportation, technology, medical, renewable energy, railroad, golf and equipment sales or rental. It also names property in transit, jobsite materials, leased equipment, installation and rigging. That sector range can help buyers frame a Markel submission; AIG’s route should be matched to its named product categories. 3 6
Surveys and property schedules
Markel says its inland-marine specialists may use on-site or desktop surveys and provide risk strategies. AIG describes marine risk consulting and engineering, including equipment or route reviews when applicable. For installation or rigging exposures, ask what survey each insurer expects, whether it affects terms and which recommendations become policy conditions. 6 3
Survey expectations for complex risks
Neither overview supplies buyer-specific limits or deductibles, and AIG notes the exact property and transit stages depend on the policy. Send each market the same equipment values, jobsite details and transit schedule so the resulting forms can be compared on causes, valuation and exclusions. 6 3
What to Confirm in Inland Marine Insurance Quotes
- Which AIG category or Markel industry product addresses your installation, leased-equipment or rigging exposure?
- Will either insurer require a desktop or on-site survey, and which limits, deductibles and conditions follow?
