A retirement services company has completed a move to scoop up a plan administration technology firm.

The Simsbury, Conn., life insurance arm of Hartford Financial Services Group Inc., Hartford, acquired TopNoggin L.L.C., Powell, Ohio.

TopNoggin develops systems that can handle data management, administration, benefits calculations and other tasks for defined benefit pension plans.

TopNoggin serves 50 clients with 375,000 in plan participants and about $4 billion in defined benefit plan assets.

The price of the deal is not available, but Hartford says it will be offering jobs to all of TopNoggin’s employees and keeping their offices in Powell.
