## Summary

AIG names several management-liability products; Liberty Mutual describes ProShield as one package combining D&O, EPL, fiduciary and crime coverage for private and nonprofit organizations. [3](https://www.aig.com/home/risk-solutions/business/management-and-professional-liability "Management & Professional Liability Insurance | AIG US") [6](https://business.libertymutual.com/commercial-insurance-solutions/management-liability/proshield/ "ProShield") [7](https://business.libertymutual.com/industries/professional-services/ "Professional services")

## 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.

## What Is Management Liability Insurance?

Management liability packages can combine D&O and employment-practices coverage for leader and workplace claims, while benefit-plan protection may be a separate part. Shared limits can let a claim in one part reduce what is available for another, so compare the limits across the quote. [8](https://content.naic.org/glossary-insurance-terms "Glossary of Insurance Terms") [9](https://www.thehartford.com/management-liability-insurance "Management Liability Insurance") [10](https://www.chubb.com/us-en/business-insurance/forefront.html "The ForeFront Portfolio") [11](https://asset.trvstatic.com/download/assets/pdo-3001.pdf/d66bd58e63c911ee99d14294a32ecb95 "Private Company Directors and Officers Liability Coverage") [12](https://asset.trvstatic.com/download/assets/lia-3001.pdf/e79a6b6c63ca11eeaa7806e978c86228 "Liability Coverage Terms and Conditions") [13](https://asset.trvstatic.com/download/assets/pdo-1100w-ind.pdf/d44fa35c63c911eea5a70eda10c0a4d0 "Private Company Directors and Officers Liability Coverage Application")

## Key Differences in Management Liability Insurance

### Liberty Mutual presents a combined package
AIG lists D&O, EPL, fiduciary, crime/fidelity and K&R products in its management-liability portfolio. Liberty Mutual describes ProShield as one package policy combining D&O, employment-practices, fiduciary and crime coverages, designed to reduce the need for separate endorsements. The published record describes private and nonprofit organizations as its intended audiences. A buyer seeking a multi-line package can compare ProShield’s bundled schedule with the specific AIG products needed, while confirming that each desired exposure is included. [3](https://www.aig.com/home/risk-solutions/business/management-and-professional-liability "Management & Professional Liability Insurance | AIG US") [6](https://business.libertymutual.com/commercial-insurance-solutions/management-liability/proshield/ "ProShield")

### AIG’s line list includes K&R; ProShield’s listed bundle does not
AIG’s portfolio includes kidnap-and-ransom alongside crime and executive coverages. Liberty Mutual’s ProShield description names D&O, EPL, fiduciary and crime, not K&R. That is a difference in the published package descriptions, not proof that Liberty Mutual cannot place K&R separately. Ask whether K&R can be added and how its terms relate to ProShield. [3](https://www.aig.com/home/risk-solutions/business/management-and-professional-liability "Management & Professional Liability Insurance | AIG US") [6](https://business.libertymutual.com/commercial-insurance-solutions/management-liability/proshield/ "ProShield")

## What to Confirm in Management Liability Insurance Quotes

- Ask Liberty Mutual whether K&R is available alongside ProShield and request the package’s forms and limits. [6](https://business.libertymutual.com/commercial-insurance-solutions/management-liability/proshield/ "ProShield")
- Confirm whether AIG’s listed products are packaged or quoted separately for your organization. [3](https://www.aig.com/home/risk-solutions/business/management-and-professional-liability "Management & Professional Liability Insurance | AIG US")

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.
