Ellyn A. McColgan, president of Fidelity Investments Distribution and Operations, has resigned in order to pursue opportunities outside of the company. McColgan joined Fidelity in 1990 and has held senior management positions within the company’s 401(k) client services division, the 403(b) business for not-for-profit institutions, the intermediary business and Fidelity Brokerage Company. In a statement announcing McColgan’s resignation, Edward Johnson, chairman CEO of Fidelity, said Rodger Lawson, who recently was appointed to oversee distribution and operations as well as other parts of the company as president of FMR Corp., will assume immediate day-to-day control over distribution, until McColgan’s replacement is named.
