Rodger A. Lawson will step down as president of Fidelity Investments at the end of March, spokeswoman Anne Crowley confirmed.
Mr. Lawson will take on a new role as an adviser to the firm. He was not immediately available for comment.
There are no current plans to name a new president, Ms. Crowley said, noting that the money management giant has operated for long stretches in the past without a president. She noted, however, that doesn't preclude a decision at some point by Fidelity Chairman Ned Johnson to appoint a replacement.
Money management sources say Fidelity has retained at least one executive search firm, Goldsmith & Co., to find a replacement for Mr. Lawson. Joseph B. Goldsmith, president, declined to comment.
Ms. Crowley said Fidelity has searches going on “all the time” for various roles at the firm.
