Research analyst Glenn Costello has left Merrill Lynch to become the co-head at the RMBS group at Fitch Ratings. Costello was hired in July 2000 to cover Merrill's real estate ABS. He will be reporting to Group Managing Director Gloria Aviotti who oversees the RMBS and CDO groups at the rating agency. Joanne Sokolowski currently heads the RMBS group at Fitch. Additionally, Costello will not be a featured panelist on the Real Estate ABS Researcher Roundtable at next week's IMN ABS West conference. However, he will still be session facilitator for the Developments in the Manufactured Housing Sector panel.
