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 Gallagher?
Gallagher’s technology specialists serve startups through global enterprises, while its executive-risk team supports IPO and M&A needs; small firms seeking one simple digital quote should compare online agencies. 4,5,6,7,8
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. 9,10,11
Key Differences in D&O Insurance
Public-listing program support
AIG offers D&O protection for executive and governance exposures, either standalone or modularly with management-liability lines. Gallagher places D&O and specifically markets program advice for SPACs through IPO and de-SPAC, and companies listing through an IPO or direct listing. It describes coordinating D&O before and after an IPO with related lines such as cyber, E&O, and representations and warranties. A company approaching a public transaction can ask Gallagher how those stages affect its program; AIG buyers should ask which form and transaction provisions apply to their placement. 3 6
Claims advocacy and carrier selection
AIG links product applications and national teams. Gallagher says its executive-risk practice has a dedicated claims advocacy team with in-house attorneys and weighs carrier qualifications, performance, client history, and preferences when selecting markets. Gallagher is arranging the placement rather than underwriting the policy, so carrier terms still govern. Buyers comparing services should identify who will advocate at claim time and review the proposed carrier’s actual policy wording and limits. 3 6
