A mixed-gender board brings a better blend of leadership skills and access to a wider talent pool.
Yet more evidence that old boys club networks that keep women out of positions of power are shooting themselves in the foot. Credit Suisse analysed 2,500 companies and found that those with more than one woman on the board were more successful than those with all male boards. And not just marginally more successful. They found organizations with women board members outperformed their all-male counterparts, by the study's metric, by 26 percent. They had 4 percent higher average growth over the last six years and a 4 percent higher return on equity.
