FM Global is an American mutual insurance company based in Johnston, Rhode Island, United States, with offices worldwide, that specializes in loss prevention services primarily to large corporations throughout the world in the Highly Protected Risk (HPR) property insurance market sector. "FM Global" is the communicative name of the company, whereas the legal name is "Factory Mutual Insurance Company". FM Global has been named the "Best Property Insurer in the World” by Euromoney Magazine.

The group agreed, and by year's end, formed the Manufacturers Mutual Fire Insurance Company, the oldest predecessor of FM Global. During the company's first 14 years, the mill owners and mutual policyholders of Manufacturers Mutual enjoyed an average 50% reduction in premiums compared with the premiums of other insurance companies. The fire prevention methods they developed, monitored by regular fire inspections for mill policyholders, resulted in fewer losses. Despite its initial success, one problem remained for the pioneer mutual insurance company: a single mutual insurance company could not withstand the financial cost of the loss of an entire
