Granite State Workers’ Compensation Manufacturers Trust

The Granite State Workers’ Compensation Manufacturers  Trust, also known as Sigma-One was started by us on February 1, 1995.  This is a very diverse group of manufacturers and the size of  Member companies can be as few as a handful of employees, while the largest Member has almost 800 employees.

Premiums for this group can be as little as $5,000 to more than $500,000.  The Membership includes almost two hundred companies that represent a myriad of different businesses including food products, electronic manufacturers, concrete blocks, precast concrete, machine shops, metal fabricators, companies that make gravel and aggregate and even a few software companies.
