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](https://www.aig.com/investor-relations "Investor Relations") [2](https://www.aig.com/home/risk-solutions/business "Business") [AIG profile](https://spot.insure/insurance-providers/aig) ## What Is Marsh McLennan Agency? Marsh McLennan Agency provides business insurance and employee health and benefits, alongside retirement, wealth, and private-client services across the United States and Canada. Its US small-business page lists six common coverage types and directs buyers to request a personalized quote by phone; the insurer and terms for a specific placement must be confirmed in the proposal. [4](https://www.marshmma.com/us/mma/about-us.html "Who We Are") [5](https://www.marshmma.com/us/solutions/small-business.html "Small Business Insurance Solutions") [Marsh McLennan Agency profile](https://spot.insure/insurance-providers/marsh-mclennan-agency) ## 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. [7](https://www.thehartford.com/business-insurance/glossary-of-business-insurance-terms "Glossary of Business Insurance Terms") [8](https://eperils.com/wp-content/uploads/2016/09/14-02-18480.pdf "The Chubb Primary Directors & Officers and Entity Securities Liability Insurance") [9](https://asset.trvstatic.com/download/assets/pdo-3001.pdf/d66bd58e63c911ee99d14294a32ecb95 "Private Company Directors and Officers Liability Coverage") ## Key Differences in D&O Insurance ### Coverage structure and described defense AIG offers D&O as standalone insurance or modularly with other management-liability products, describing protection for executive and corporate-governance exposures. Marsh McLennan Agency describes coverage for alleged wrongful acts by directors or officers, including defense costs for civil and criminal actions and investigations, with actual coverage controlled by the issued policy and jurisdiction. Those descriptions give buyers distinct questions: ask AIG how its modules combine, and ask MMA which proceedings and defense costs appear in the actual form. [3](https://www.aig.com/home/risk-solutions/business/management-and-professional-liability/directors-and-officers-liability "Directors & Officers (D&O) Liability Insurance | AIG US") [6](https://www.marshmma.com/us/solutions/executive-and-professional-liability.html "Executive and Professional Liability | MMA") ### How the placement begins AIG links Management and Professional Liability applications and national product contacts. Marsh McLennan Agency invites organizations to contact an adviser or specialist, but the cited page does not promise a quote, binding, or effective date. A buyer can use AIG’s application route or begin a discussion with an MMA adviser, then compare the carrier, limits, and timing only after receiving a proposal.

[6](https://www.marshmma.com/us/solutions/executive-and-professional-liability.html "Executive and Professional Liability | MMA") - Ask AIG for the standalone or modular form, limits, and application requirements.
