Natan Tiefenbrun, head of international operations at Instinet, the brokerage group set to merge with Nasdaq in a $1.8bn (€1.5bn) deal, is to leave after a management restructuring.
New York-based Instinet told Financial News that his departure after 12 years at the group was amicable. Tiefenbrun, who was appointed president of Instinet's international division in December 2003, will leave in the next few weeks.
