Workers’ Compensation carrier A.I.M. Mutual announced that will start selling policies in Maine as it continues its expansion throughout New England.

A.I.M., which started in 1989 in Massachusetts, expanded to New Hampshire in 2001. In 2013, it started providing workers’ compensation coverage in Connecticut. And in 2017, A.I.M. started issuing policies in Vermont.

“We started out in 1989 in response to a workers’ compensation crisis in Massachusetts,” President and CEO Michael Standing said in a statement. “Much of our business focus continues to be on Massachusetts, but we can now extend coverage to employers who have operations in other states.”

A.I.M. is rated “A (Excellent)” by A.M. Best and has more than $650 million in assets.
