UnumProvident Corp. is changing its name to Unum Group.

The Chattanooga, Tenn., employee benefits company says it wants to show it is changing its style while keeping the “brand equity” invested in the Unum name.

Once regulators approve the change, the company’s 3 primary business units will be known as Unum US, Unum UK and Colonial, the company says.

The company says it will not change the names of subsidiaries such as Unum Life Insurance Company of America, Provident Life and Accident Insurance Company, the Paul Revere Life Insurance Company and Colonial Life & Accident Insurance Company.
