I firmly believe boards need to be less squeamish about prying into their senior executives’ private lives, particularly when divorce is looming, because the corporate consequences can be grave. Now researchers at Stanford’s Graduate School of Business have broadened the debate to suggest that shareholders should worry about chief executives’ marital disharmony, too.
Divorce, they write, could undermine CEOs’ control and influence, affect their “productivity, concentration and energy levels”, and have an impact on their attitude to risk. They cite Rupert Murdoch’s split from Wendi Deng and the divorce of Harold Hamm, CEO of Continental Resources, from his wife. News of the first, thanks to a pre-nuptial agreement, left News Corp shares unmoved; news of the second, with no pre-nup, knocked 2.9 per cent off Continental Resources’ stock price as investors worried about the fate of Mr Hamm’s 68 per cent stake in the group.
