Mr Rochussen served as the chief executive of J O Hambro Capital Management (JOHCM) when it was acquired by BT Investment Management in 2011, and continued to serve as a director on the board of the former in addition to his role as group executive.
The company announced to the market that Mr Rochussen had resigned to invest in a UK-based boutique fund, which he will become chief executive of at the end of his six-month notice period with the company.
BT Investment Management group chief executive Emilio Gonzalez said Mr Rochussen had “made an exceptional contribution” to the business during his time working at the company.
“While I am disappointed that he is leaving, I respect his decision and wish him every success in his new endeavour,” he said,
Mr Rochussen said it had been “a pleasure and a privilege” to work with both JOHCM and BTIM, but that he felt his “vision has been fulfilled” and his job with both businesses done.
“The business is in great shape, there is a very strong management team with deep knowledge and experience of the global asset management industry and Ken Lambden in place as chief executive of JOHCM,” he said.
“I feel now is the right time for me to take on my next challenge.”
BTIM said that Mr Rochussen’s resignation was effective immediately and that he would be on “gardening leave” for the duration of his notice period, but that he will assist the company with “transitional matters” as required.
Mr Gonzalez said he would take charge of Mr Rochussen’s international business development responsibilities until the business was able to “undertake a full assessment of internal and external candidates for that role”.
