Chip Stevens, v.p. at Merrill Lynch, has left the firm to relocate to the U.S. with another investment bank. Dale Lattanzio, managing director and head of the global principal investment ans secured financing group, said Stevens had left of his own accord and would be replaced, although it had not been determined whether the hire would be internal or external. Lattanzio would not elaborate on the firm Stevens had joined. Stevens had already left Merrill and could not be reached.
