George M. Jamgochian has been named interim president and chief executive officer of Union Bank of Switzerland's asset management unit in New York.
He succeeds Jim McCaughan, who left UBS last week to join Pimco Advisors Holdings, Stamford, Conn., as president.
For the past two months, Mr. McCaughan had been working for Region Americas, a unit overseeing transition issues related to Union Bank's pending merger with Swiss Bank Corp.
Mr. Jamgochian said he will act as UBS' asset management chief until the bank closes its merger with Swiss Bank Corp.. The deal, scheduled to close in June or July, would create United Bank of Switzerland.
At that time, Mr. Jamgochian will take charge of marketing and client relations for the merged bank-the same job he held at UBS, he said. Swiss Bank's Gary Brinson will become president of United Bank's U.S. asset management unit, which will be called UBS Brinson Inc.
UBS Brinson will manage about $340 billion of institutional assets and $580 billion of private banking and retail assets, said Mr. Jamgochian.
