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 Lockton?
Lockton suits technology companies and larger businesses seeking a broker across cyber, D&O, property, liability and benefits; small firms wanting an instant standard quote should compare digital agencies. 4,5,6
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. 8,9,10
Key Differences in D&O Insurance
Program design and insured parties
AIG offers D&O as standalone coverage or modularly with other management-liability policies. Lockton brokers a three-part design: Side A for individuals when the company cannot indemnify, Side B reimbursement, and Side C entity coverage, with broader entity coverage described for private and nonprofit organizations than public companies. Lockton also says its placements can extend to trustees, employees, contractors, committee members, volunteers, subsidiaries, spouses, and estates, subject to the policy. Buyers should compare the proposed insured definition with the AIG form. 3 7
Claims advocacy
AIG says its D&O product protects executive and governance exposures and provides applications through its product team. Lockton describes integrating experienced insurance and claims counsel within the broking team from the start of the relationship, rather than separating claims advocacy as a later service. That is a documented brokerage-service distinction, not a coverage grant or insurer decision. Ask Lockton who handles a claim and ask AIG which carrier claims contacts and defense-counsel provisions appear in the proposed policy. 3 7
