Mike Camacho, formerly co-head with Adam Green of North American structured investments marketing in New York, has been promoted to head of the group. Green, now simply managing director in the group, reports to Camacho, who in turn reports to Tony Best, head of Europe, Middle East and Africa investor client management in London. Best is now in charge of third-party distribution for globalized products. Camacho and Green referred questions to a spokesman, and Adam Castellani, spokesman, declined comment. The shake-up is a continuation of the global realignment of key products groups that has been going on since January.
