Jeffrey Burch, formerly co-head of credit at Investec Asset Management, will leave at the end of June to pursue other opportunities.
Theodore Stamos, who helps oversee around $70 billion of assets at the firm as co-head of credit, will replace Mr. Burch and run the credit unit alongside portfolio manager Simon Howie, Investec said in an e-mailed statement.
Mr. Burch joined Investec from Blue Mountain Capital Management, a specialist credit hedge fund, in June 2009. He was not immediately available for comment.
