Thank you for the question.
Very clearly, companies that have diverse management teams and/or diverse boards perform better from a financial perspective; they have higher earnings, higher return on capital, higher growth and earnings. They also perform better from an environmental perspective and in times of stress, for example, when a CEO resigns. There's a whole bunch of reasons for that.
To achieve that, you've got to get to a minimum critical mass of diversity on a board. Some of the research studies say that there need to be at least three women on boards, making up at least 30% of the board. It's the combination of men and women together that creates the improvement. With one or the other, you cannot get the improvement, but together you can.
