Asset management firm BlackRock announced Ed Fishwick will succeed co-founder Ben Golub as chief risk officer at the end of the month.

Fishwick, who has served as Golub’s “long-time partner” for more the 15 years, will relocate from London to New York for the role, according to a memo to employees seen by Compliance Week. Fishwick currently serves as global co-head of risk and quantitative analysis; he will continue to lead the team in his new role and join the global executive committee.

Fishwick will report to President Rob Kapito.

A former head of investment risk management and investment process research at AXA Investment Managers, Fishwick joined BlackRock in 2003, according to his LinkedIn profile.

Golub decided to “step back from his day-to-day duties,” according to the memo, but will remain a senior adviser for the firm. He has been with BlackRock for 34 years.

BlackRock Chief Executive Larry Fink and Kapito commended Golub for moving the asset management business “in new directions” in the memo.
