NEW YORK (CNNfn) -Mutual fund giant Fidelity Investments said Tuesday its Chief Financial Officer Gerald Lieberman will resign at the end of the month to pursue other interests.
Fidelity, a unit of privately held FMR Corp., named company executive Stephen Jonas to replace Lieberman in the CFO post effective March 31.
Lieberman, 51, is resigning to "pursue entrepreneurial and other interests outside the company," Fidelity said in a statement.
Jonas, who is currently senior vice president of finance and administration for Fidelity Personal Investments & Brokerage Group, will also serve as a member of Fidelity's operating committee.
"It's a great disappointment that (Gerald Lieberman) has decided to resign from the company," James C. Curvey, Fidelity's chief operating officer, said.
Lieberman oversaw several "critical" corporate functions, including information systems, global risk management, accounting, and others, Curvey said.
Lieberman joined FMR in 1993 as senior vice president of administration for and was named Fidelity CFO in 1995.
Jonas joined Fidelity in 1987 as vice president of finance for Fidelity Investor Information Services.
Boston-based Fidelity, the nation's largest mutual fund company, managed a total of $606.6 billion in assets at the end of 1997.
