When JPMorgan Chase & Co. shareholders will vote in the company's annual meeting Tuesday on whether the board ought to split Jamie Dimon's dual roles as board chairman and bank chief executive, many of the voters will represent firms - like Malvern-based mutual fund giant Vanguard Group - that are themselves run by chairman-CEOs, reports Bloomberg here.

“People just like him are going to vote on this,” Erik Gordon, University of Michigan law and business professor, told Bloomberg. “If you’ve told your own board that the best structure for the sake of the company is to combine the roles, then how do you turn around and say, ‘But that’s not true for JPMorgan?’”
