[3](https://www.aig.com/home/risk-solutions/business/aig-programs "AIG Programs Insurance") [6](https://business.libertymutual.com/commercial-insurance-solutions/property/equipment-breakdown/liberty-mutual-equipment-re/products/ "Products: Liberty Mutual Equipment Re") [7](https://business.libertymutual.com/commercial-solutions/property/ "Property")

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 Equipment Breakdown Insurance?

Equipment-breakdown coverage can help repair covered machinery or building equipment after a mechanical or electrical failure. It fits businesses that depend on equipment to operate; check whether lost income, spoilage and utility failures are included. [8](https://www.iii.org/article/understanding-commercial-package-policies "Understanding Commercial Package Policies") [9](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm "Commercial Insurance Guide") [10](https://www.travelers.com/risk-control/specialties/equipment-breakdown "Equipment Breakdown") [11](https://www.munichre.com/content/dam/munichre/hsb/hsb-iic/documents/hsb-techadvantage-equipment-breakdown-coverage-form.pdf/_jcr_content/renditions/original./hsb-techadvantage-equipment-breakdown-coverage-form.pdf "HSB TechAdvantage Equipment Breakdown Coverage Form")

## Key Differences in Equipment Breakdown Insurance

### Breakdown Causes and Downtime Terms

Liberty Mutual Equipment Re names electrical, mechanical, and pressure-system breakdown, with resulting business income and extra expenses only when included in the base policy. AIG lists equipment breakdown within selected industry programs but does not specify causes, waiting periods, or interruption terms in its directory. A manufacturer or facility with pressure equipment should ask Liberty Mutual which resulting-loss terms are part of the offered form and ask AIG for the relevant program wording and equipment schedule. [6](https://business.libertymutual.com/commercial-insurance-solutions/property/equipment-breakdown/liberty-mutual-equipment-re/products/ "Products: Liberty Mutual Equipment Re") [3](https://www.aig.com/home/risk-solutions/business/aig-programs "AIG Programs Insurance")

### Reinsurance Team Versus Program Component

Liberty Mutual’s reviewed page describes Equipment Re and provides a direct team contact, but does not establish how a particular business obtains or binds a policy. AIG’s directory likewise lists the coverage only within specified programs and does not state a universal buyer route. Before comparing, establish whether Liberty Mutual is offering a reinsurance relationship or a direct placement, and identify the insurer and policy form for the AIG program. [6](https://business.libertymutual.com/commercial-insurance-solutions/property/equipment-breakdown/liberty-mutual-equipment-re/products/ "Products: Liberty Mutual Equipment Re") [3](https://www.aig.com/home/risk-solutions/business/aig-programs "AIG Programs Insurance")

## What to Confirm in Equipment Breakdown Insurance Quotes

- Ask Liberty Mutual which policy form and placement route apply and whether business income is included or optional. [6](https://business.libertymutual.com/commercial-insurance-solutions/property/equipment-breakdown/liberty-mutual-equipment-re/products/ "Products: Liberty Mutual Equipment Re")
- Ask AIG for the program’s breakdown trigger, waiting period, deductible, and resulting-loss provisions. [3](https://www.aig.com/home/risk-solutions/business/aig-programs "AIG Programs Insurance")
