Nomura Holdings Inc. has appointed Chief Operating Officer Takumi Shibata to head the integration of units acquired from Lehman Brothers Holdings Inc.

Shibata, 55, will be in charge of integrating Lehman operations in Asia and Europe, Nomura spokesman Michiyori Fujiwara said Monday.

Shibata's task involves taking over more than 5,000 employees from New York-based Lehman, which filed for bankruptcy Sept. 15.

Japan's largest brokerage said last week it will buy the U.S. brokerage's equities and investment-banking businesses in Europe and the Middle East, accounting for about 2,500 new employees, in addition to taking over about 3,000 Lehman workers in the Asia-Pacific region.

Nomura named Sadeq Sayeed, David Farrant and Paul Spanswick as senior managing directors, a newly created position, to help oversee the integration starting Wednesday.

Sayeed, who became a special adviser to Nomura in 2000, will oversee the European transition along with Spanswick, who shares the chief operating officer title in the region, Fujiwara said. Farrant will oversee global human affairs.

Sayeed was named executive vice chairman of Nomura International PLC in London and will be chief executive of the newly acquired businesses in Europe on completion of the transaction, Nomura International said separately Monday.

Meanwhile, Merrill Lynch & Co. said it hired James Chapman and five other bankers from Lehman to help boost its advisory and capital markets team for the power industry in Asia.

Chapman was hired as director and head of Asia power investment banking. Other hires in Hong Kong include Anoop Chaudhry, who joins as a vice president, a position he also held at Lehman.
