Lehman Brothers has added a new member to its London-based residential mortgage-backed securitization team. Lloyd Cochrane, formerly an analyst at Fitch Ratings in London focusing on RMBS will join Lehman in September, says a Lehman spokeswoman. Cochrane will concentrate on RMBS origination and report to Amany Attia, head of European structured finance. His position is newly created. Calls to a Fitch spokeswoman were not returned.
