Unitrin business insurance writes commercial package coverage primarily for small businesses. Consummation of the transaction is subject to regulatory approval.

Barry Zyskind, president and CEO of AmTrust, said: This acquisition offers us the opportunity to obtain and develop a book of business that fits our focus on small businesses and to complement and expand the products we offer to our existing small workers’ compensation and property and casualty customers.
