Robert McCann, the recently appointed chief of UBS' wealth management business for the US, has assembled a team of former Merrill Lynch executives to help him return the struggling unit to profitability.

McCann, who ran Merrill's wealth management operation, including stockbrokers, announced late Monday that four former colleagues from Merrill -- including Bob Mulholland, who held a number of positions in his 25 years at Merrill, including head of Americas for the global private client group, and Brian Hull, most recently the head of Merrill's private bank and investment group -- will join him at UBS.
