Mark Marinella resigned as managing director and head of fixed income at Columbia Management Group, effective April 11. Charles Salmans, Columbia spokesman, confirmed Mr. Marinellas departure and said a search is under way for his replacement, but he did not offer further comment. Mr. Marinella could not be reached for details about his departure and future plans.
Portfolio managers Bonny Boatman, Marie Schofield and Steven Luetger will assume oversight of Columbias fixed-income investment operations until a replacement is found, Mr. Salmans said.
Mr. Marinella joined Columbia in August 2002; he had been co-head of fixed income at State Street Research & Management.
