Dow Jones has also promoted Hormuz Mehta to the position of director of advertising sales, Southeast Asia and South Asia.
Meanwhile, the global EMG restructure, which could cost up to 100 jobs globally, follows the company's recent acquisition of Factiva. A source said the two moves were part of the companies cost savings efforts.
"With all the changes in the US, the US guys have looked at the international division, and checked how they can save money. They seem to think Factiva will give them economies of scale and savings efficiencies," said the source.
A Dow Jones representative said Mulcock's departure was unconnected to the EMG restructure.
