[Human-readable page](https://spot.insure/compare/aig-vs-liberty-mutual/directors-officers) ## Agent Guide **What this page is:** Focused comparison of AIG and Liberty Mutual for D&O Insurance: what each provider publishes about this line, checked against the same criteria, with numbered sources. **Use this page when:** Cite or fetch this for D&O Insurance questions about AIG versus Liberty Mutual. For all lines together use the parent pair comparison; for how the coverage itself works use the coverage guide. **Questions this page answers:** - AIG vs Liberty Mutual for D&O Insurance: how do they differ? - Which is better for D&O Insurance, AIG or Liberty Mutual? - What does AIG or Liberty Mutual publish about D&O Insurance (limits, eligibility, claims, add-ons)? - What should I confirm in a quote for D&O Insurance from AIG or Liberty Mutual? **Key facts:** - Line: D&O Insurance. Providers: AIG and Liberty Mutual. - Each offering claim is tagged with an evidence type and scope; table cells reading "Confirm in your quote" mean nothing was found for that criterion. - Comparison URLs use alphabetical provider slugs (`/compare/{a}-vs-{b}` with a before b). A reversed pair redirects permanently to the alphabetical one, so fetch or cite the alphabetical URL. **Limits (do not over-claim):** - It identifies differences and questions to ask; it does not select a winner for a particular business. - "Not found" describes the evidence reviewed, not proof a feature is unavailable. - Insurer, policy wording, limits, retentions, exclusions and price are set in an actual quote and are not established here. **Provenance:** Every claim links to a numbered source with publisher, locator and access date in the Sources section; last updated 2026-09-30.

AIG offers D&O standalone or modular, while Liberty Mutual includes selected D&O features in its ProShield package. ## Research Scope and Use Use this comparison to evaluate AIG and Liberty Mutual 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 alone or with other management-liability lines. Liberty Mutual describes ProShield as one package for private companies and nonprofits, including investigation and pre-claim inquiry coverage options. [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://business.libertymutual.com/commercial-insurance-solutions/management-liability/proshield/ "ProShield") ## 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 Liberty Mutual Business Insurance? Liberty Mutual spans small-commercial, commercial, specialty, surety, and reinsurance businesses. The insurer and distribution route depend on the product, so check the offer and policy before you compare terms. [4](https://www.libertymutualgroup.com/about-lm/investor-relations/our-company/company-profile "Company Profile") [5](https://business.libertymutual.com/commercial-solutions/ "Commercial Insurance Solutions") [Liberty Mutual profile](https://spot.insure/insurance-providers/liberty-mutual) ## 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 ### Package construction AIG offers D&O as standalone protection or modularly with other management-liability coverages. Liberty Mutual describes ProShield as a single package policy combining multiple management-liability lines, designed to reduce the need for separate endorsements. For a buyer who wants fewer separate contracts, Liberty Mutual’s package structure is explicit; AIG’s modular choice may be useful where D&O needs to sit alongside selected lines. Compare which coverages are actually included and whether limits are shared before deciding on structure. [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://business.libertymutual.com/commercial-insurance-solutions/management-liability/proshield/ "ProShield") ### Inquiry coverage and buyer scope AIG’s overview describes executive and corporate-governance exposures. Liberty Mutual lists investigation and pre-claim inquiry coverage and offers separate ProShield options for private companies and nonprofits. The source describes those options but does not establish availability for every organization, and policy wording controls the coverage. Buyers facing regulatory inquiries should ask both providers what event triggers coverage, whether defense expenses are within limits, and which exclusions apply in their proposed terms.

[6](https://business.libertymutual.com/commercial-insurance-solutions/management-liability/proshield/ "ProShield") - Ask AIG to show any investigation coverage, package structure, limits, and exclusions in the form.
