Credit Suisse’s $10 billion funds-of-funds business appears to be undergoing a management shuffle, with two senior executives having left the group last month. Boris Arabadjiev, the Swiss bank’s funds-of-funds chief, left in early February. He originally joined the firm in 2001. Lance Babbit, a director in Credit Suisse’s asset management division and head portfolio manager within its funds-of-funds group, left shortly thereafter.
