The Chartered Financial Analyst Institute has appointed an interim CEO after John Rogers stepped down.
Rogers, the president and chief executive of the US-based investment standards body, announced his resignation in March. He then told the board of a personal matter representing a potential conflict of interest.
After an independent review, Rogers and the board agreed to appoint an interim CEO, former Fidelity Investments' senior executive Dwight D. Churchill.
A CFA Institute spokesman said: "Dwight offers strong leadership as CFA Institute continues to execute its mission, and we do not anticipate the transition to have any effect on fund managers in the UK.
"He is a highly regarded investment professional with over 30 years of global leadership experience, including a long history and affiliation with CFA Institute. As a past governor and past board chair, Dwight knows the CFA Institute well and will provide stability and continuity as the organisation transitions to a new permanent president and chief executive."
Churchill held a number of senior positions at Fidelity, including head of the fixed income division, head of equity portfolio management, and overseer of the Fidelity equity office in Hong Kong. He retired from the firm in 2009.
