"This year, we analyzed U.S. companies over a five-year period (2011-2016). U.S. companies that began the period with at least three women on the board experienced median gains in Return on Equity (ROE) of 10 percentage points and Earnings Per Share (EPS) of 37%. In contrast, companies that began the period with no female directors experienced median changes of -1 percentage point in ROE and -8% in EPS over the study period (see below exhibits)."
