Bart Grenier was appointed head of asset management at Fidelity Investments effective mid-February, a spokesman said.
Mr. Grenier will replace Steve Neff, who is set to retire March 31, according to an internal memo seen by Pensions & Investments.
"(Mr. Neff) will be remembered as a skilled steward for Fidelity's mutual fund shareholders and institutional clients, as well as an innovative leader of technology development. But perhaps most lasting, he has been a compassionate advocate of diversity and inclusion, skills-based volunteering and talent development," said Abby Johnson, chairman and CEO of the firm, in an emailed comment.
Further, Andrew McCaffery was appointed global CIO, asset management at Fidelity International in the U.K., a spokeswoman said.
Mr. McCaffery is set to replace Mr. Grenier, who has held this position since January 2018.
Mr. McCaffery joined Fidelity International in July as global CIO for alternatives and solutions and was deputy global CIO of asset management. Prior to joining Fidelity, he was global head of strategic client investments and global head of alternatives at Aberdeen Standard Investments.
