Hedge fund firm Man Group has announced a management reshuffle, naming new finance and investment heads, just weeks after its chief executive left to run Pacific Investment Management Co.

Man Group, the world's largest listed hedge-fund firm by assets, said on September 2 that Jonathan Sorrell is stepping down as chief financial officer, while his role as president of Man Group is expanding to include several new strategic and commercial areas including sales, corporate strategy, and mergers and acquisitions.
