A financial services giant has revamped the organizational chart for its life operations.

The Simsbury, Conn., arm of Hartford Financial Services Group Inc. now is dividing the operations into 4 major “market groups,” up from 2.

In the past, the company put U.S. wealth management in one group and international wealth management and group benefits in a second group.

Now, the company will have individual, employer, institutional and international market groups, Hartford says.

Brian Murphy, who has been an executive vice president in the individual life division, will run the individual market group.

James Davey, a Hartford retirement plans executive, will run the employer markets group, and Stephen Joyce, who helped start Hartford’s institutional solutions group in 2002, will run the institutional markets group.

Peter Smyth, who once worked for ING Groep N.V., Amsterdam, in Hong Kong, will run the international markets group.

Another executive, Sharon Ritchey, will be in charge of a service and technology operation that will support all Hartford Life market groups, Hartford says.

Ritchey has been chief operating officer of the U.S. wealth management group.
