Credit Suisse has made a flurry of senior appointments to help integrate its investment bank with UBS after the completion of its emergency takeover, as one of its most senior dealmakers is set to depart.

David Wah, a 30-year veteran who was previously Credit Suisse's global head of investment banking, is stepping down, according to a memo seen by Financial News and confirmed by a bank spokesperson. His departure follows David Miller, the bank's co-head of investment banking, who is also leaving as Michael Ebert takes the reins of the unit.
