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 Marsh?
Marsh suits technology and larger businesses seeking specialist cyber placement or broad global risk advice; small firms wanting a quick standard quote should compare its MMA route or digital agencies. 4,5,6,7
What Is Directors and Officers Insurance?
D&O insurance can help pay covered defense costs and losses from claims against company leaders over management decisions. If your organization has a board or executives, check whether the company itself is insured and whether legal bills reduce the limit. 10,11,12
Key Differences in D&O Insurance
Coverage parts and organization type
AIG offers D&O standalone or modularly alongside other management-liability lines. Marsh explains Side A as personal-asset protection when the organization cannot or will not indemnify, Side B as reimbursement for indemnification, and Side C as entity protection, generally limited to securities claims for public companies. Marsh also notes that public-company leaders often face securities suits, while private and nonprofit organizations more often face employment-related claims. This helps buyers frame which coverage side and claim patterns deserve attention in an AIG form or a Marsh-arranged program. 3 8
Emerging governance exposures
AIG’s overview focuses on executive and corporate-governance exposures, while Marsh identifies ESG scrutiny around emissions, labor practices, board diversity, and compensation as a source of added regulatory, legislative, or litigation pressure. Marsh also notes cyber-related liability across organization types. A buyer should ask how the proposed wording treats those specific allegations and whether entity coverage changes by organization type; the overview alone does not establish coverage for any one event. 3 8
