The Wall Street executive merry-go-round keeps spinning. The latest to make a change is Erin Callan, who leaves Lehman Brothers Inc. to run Credit Suisse Group's global hedge fund business.
Callan leaves Lehman after 13 years, culminating in a demotion last month from CFO to an executive at Lehman's investment bank division. The demotion followed Lehman's unexpected $3 billion loss last month. Callan starts her new job Sept. 2, leading Credit Suisse's hedge fund as well as joining the
investment bank's management committee and its global client steering
committee. - Baz Hiralal
