## Research Scope and Use

Use this comparison to evaluate AIG and Aon for D&O Insurance against the same documented criteria. It identifies differences and questions to confirm; it does not select a winner for a particular business. Offering claims are what each provider publishes about this line unless marked otherwise. “Not found” describes the evidence reviewed, not proof that a feature is unavailable. Confirm the insurer, policy wording, limits, retentions, exclusions and cost in an actual quote.

## Summary

AIG offers D&O standalone or modular with other management-liability coverages. Aon describes Side A individual protection, Side B reimbursement, and Side C entity coverage as parts of D&O program design. [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.aon.com/en/capabilities/risk-transfer/directors-and-officers-liability-insurance "Directors’ and Officers’ (D&O) Liability Insurance")

## 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](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 Aon?

Aon’s U.S. Commercial Risk terms describe brokerage for certain insurance programs, while its Middle Market page describes a dedicated practice for mid-sized organizations across North America. The public materials reviewed do not identify the licensed producer or insurer for a particular placement. Ask which entity will produce each line and which insurer will issue the policy; request jurisdiction details for the proposed placement and ask how compensation and claim notice work for your account. [4](https://www.aon.com/en/about/leadership-and-governance/brokerage-terms-of-service-for-commercial-risk-solutions-us "Commercial Risk Solutions U.S. Brokerage Terms of Service") [5](https://www.aon.com/en/capabilities/middle-market-clients "Middle Market Clients")

## 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

### Product structure and policy parts

AIG offers D&O either as standalone insurance or modularly with other management-liability coverages. Aon acts as broker and explains Side A protection when a company cannot indemnify an individual, Side B reimbursement when it does, and Side C entity coverage, with public- and private-company differences. This makes Aon’s page useful for discussing program architecture, while AIG’s page describes a carrier product route. Ask AIG which parts appear in its form and ask Aon how it would arrange those protections for your company. [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.aon.com/en/capabilities/risk-transfer/directors-and-officers-liability-insurance "Directors’ and Officers’ (D&O) Liability Insurance")

### Eligibility and program support

AIG links Management and Professional Liability application forms and national product contacts. Aon describes its D&O brokerage audience as public and private companies, but does not publish an underwriting eligibility schedule or name the insurer for a specific placement. Aon also says its brokerage and claims teams collaborate on negotiations and uses insurer-selection analytics and a D&O Risk Analyzer. Buyers should treat that as advisory support, then verify the selected insurer, application requirements, and issued terms. [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.aon.com/en/capabilities/risk-transfer/directors-and-officers-liability-insurance "Directors’ and Officers’ (D&O) Liability Insurance")

## What to Confirm in D&O Insurance Quotes

- Ask AIG whether the quote is standalone or modular and identify its Side A, B, and C grants. [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")
- Ask Aon to name the carrier and show entity and individual coverage in the proposed wording. [6](https://www.aon.com/en/capabilities/risk-transfer/directors-and-officers-liability-insurance "Directors’ and Officers’ (D&O) Liability Insurance")

## AIG Reviews

Review Score: 4.4 / 10 from 2 rated sources, equally weighted.

Customer ratings for AIG are low: Trustpilot shows 1.9 out of 5 from 252 reviews, and NerdWallet gives 2.5 stars and notes more claims complaints than expected. These pages cover many AIG products and countries, so they only loosely describe business insurance.

- NerdWallet: NerdWallet editorial rating 2.5 (stars). NerdWallet’s editorial business-insurance comparison; the AIG entry concerns commercial liability and property insurance, not a quantified policyholder-review sample.

## Aon Reviews

Review Score: 6.1 / 10 from 3 rated sources, equally weighted.

Public ratings for Aon are low: Trustpilot shows 1.2 out of 5 from 782 reviews, and BBB shows 1.6 from five. Aon is a global firm, so those pages mostly reflect other parts of the business, not large U.S. commercial accounts.
