American Century Investments will be the new name of the mutual fund company formed last year when Twentieth Century Mutual Funds merged with Benham Group.
The firm has $2.4 billion of tax-free assets under management out of a total of $53 billion in more than 60 stock and bond funds.
But even as the company is changing its name, most of the funds will continue to carry either the Twentieth Century or the Benham label.
In a reorganization to take effect with the company name-change Jan. 1, all of the bond and money market funds - most of which were brought to the merger by Mountain View, Calif.-based Benham - will keep the Benham name. There are 40 bond funds with $11.6 billion of assets.
The combined firm's eight aggressive-growth stock funds with $32.5 billion under management, brought to the merger by Kansas City, Mo.-based Twentieth Century, will continue to bear that company's name.
A newly created third group of 12 conservative equity, asset allocation, and specialty funds with $6.3 billion under management will be called the American Century funds.
