Lehman Brothers is believed to be looking to hire a European head of its collateralized debt obligation business. The new recruit is expected to sit in between the European structured credit trading department, headed by Mark Ames, and the European structured finance department, headed by Amany Attia. Ames would not comment on the hire, but said there is a joint venture between the two departments for securitized products. He added that Lehman does not have a European head of CDOs at present. Attia was traveling and could not be reached.
