Bob Yerbury is to step down as chief executive of Invesco Perpetual in September.
Yerbury will retain his role as chief investment officer but will be passing his chief executive role to James Robertson.
Currently based in Atlanta, Robertson is head of technology and operations for Invesco and has a total of 25 years experience in the industry. Yerbury will work with Robertson through a transition period.
Yerbury has been at Invesco Perpetual for 25 years and has held the chief executive and chief investment roles since 2004. He has seen the group become the biggest asset manager in the UK with 29.5bn of assets under management.
In addition to his chief executive and chief investment officer roles, Yerbury also manages a series of international funds for the company, including the 1.36bn international equity, 245.9m world growth and 217.4m world income funds.
Invesco says the management structure will remain unchanged and Yerbury will continue with his fund management roles.
