Nomura Holdings lost two more of its senior executives a few weeks after the firm paid out the bonuses it assured to former Lehman Brothers employees when it took over the New York brokerage in 2008, Reuters reports.

Jane Wang, the vice chairman of China investment banking, and Goeffrey Feldkamp, the head of equity capital markets for Asia Pacific ex-Japan, have reportedly resigned.

The company had offered guaranteed bonuses to Lehman staff when it acquired the business two years ago, in an attempt to retain a large number of the latter's existing manpower for at least two years. Market observers had predicted an exodus of ex-Lehman bankers once these pay outs had been completed.

Ms Wang's and Mr Feldkamp's departure come on the heels of Asian head of equities Siggi Thorkelsson's and co-head of fixed income Thomas Siegmund's departures this month - both ex-Lehman bankers. The Japanese brokerage had also announced major changes to its senior management team last week as part of its annual review, as reported by WealthBriefingAsia.

Nomura has declined to comment on the latest departures.
