A Glastonbury-based national consulting firm specializing in retirement and employee benefits has agreed to pay the U.S. Department of Labor $1.27 million to resolve allegations that it retained certain fees that should have been passed on to clients.

The investigation conducted by the Labor Department’s Employee Benefits Security Administration focused on USI Advisors Inc., a subsidiary of USI Consulting Group, a Goldman Sachs Capital Partners Co. based in Glastonbury.
