#ChangePays: Although Still Underrepresented, Women in the C-Suite are Driving Profitability

The New York Times noted that “fewer large companies are run by women than by men named John”, in an article published in 2015. “The Johns” were in second place by year-end 2016, but not by much. Although female executives remain grossly underrepresented in the C-suite, this small victory for gender inclusion underscores a changing dynamic. Did this change pay?

In one of the most comprehensive studies of its kind, a new report from the S&P Global Market Intelligence Quantamental Research Team examines the performance of firms that have made female appointments to their CEO and CFO positions. This work provides a number of significant empirical insights:

• The study finds that firms with female CFOs are more profitable and generated excess profits (defined as firm profits minus the average profits of the firm’s sector peer group) of $1.8 trillion over the study horizon.
• Firms with female CEOs and CFOs have produced superior stock price performance, compared to the market average. In the 24 months post-appointment, female CEOs saw a 20% increase in stock price momentum and female CFOs saw a 6% increase in profitability and 8% larger stock returns. These results are economically and statistically significant.
• Firms with a high gender diversity on their board of directors were more profitable and larger than firms with low gender diversity.
• Firms with female CEOs and CFOs have a demonstrated culture of Diversity and Inclusion (D&I), evinced by a larger representation of females on the company’s board of directors. Firms with female CEOs have twice the number of female board members, compared to the market average (23% vs 11%).
• Analysis of executive biographies suggests that one driver of superior results by females may be that females are held to a higher standard. The average female executive has characteristics in common with the most successful male executives, suggesting that common attributes drive success among males and females, alike. Overall, the attributes that correlate with success among male executives were found more often in female executives. This finding refutes the commonly held belief in ‘token’ female executives.

Firms with female CFOs were more profitable and generated excess profits of $1.8 trillion

The study finds that firms which appointed a female CFO had a larger quarterly gross profit and larger EBITDA, relative to the firm’s asset base, by 10.2% and 7.5%, respectively. Moreso, these firms were able to widen the profitability gap in the first 24 months after appointing a female CFO, underscoring the skill of their newly appointed executive.

Over the 17-year period for the study, firms with female CFOs generated $1.8 trillion more in gross profit than their sector average. The researchers do note that the less than 300 firms with female CFOs in the study prior to 2009 did see a retracement in excess profitability. However, from 2009 forward, the number of firms with female CFOs, and the profits those firms generated, increased substantially.

Firms with female-gendered CEOs and CFOs exhibit superior operating metrics and stock price performance.

The figure on the left shows the difference between the percentages of females on the firms’ board of directors by the gender of the CEO and CFO. The report finds that firms with a female CEO have a board of directors comprised of 23% females, compared to just 11% for firms with a male CEO. Although the same comparison is not as stark for the CFO position (14% vs. 11%), the results were directionally and statistically consistent. The larger number of females across multiple positions within a firm is an indication that firms adopt a culture of diversity and inclusion (D&I).

On the right, the figure shows that firms with female CEOs saw an increase in stock price momentum, a measure of positive price trend, and female CFOs saw larger stock returns, compared to their male counterparts in the executives’ first 24 months in office.

Firms with high gender diversity on the board have been more profitable

Firms in the study were separated into high and low board gender diversity, at each date cross section. (Diversity assignments were performed within each Global Industry Classification Standard sector and then combined to form sector-neutral high and low groups.) Those with high gender diversity had a higher gross profit relative to their asset base by 1.7%.

High diversity boards were comprised of 19% females whereas low diversity boards were comprised of less than 4% females. Approximately 2/3rd of boards in the low diversity category had zero females. Board diversity also bears a high correlation to company size, where the average market capitalization of firms with high gender diversity on the board are about 4 times larger than those with low board diversity.

So, what are females doing differently than males to drive the observed differences highlighted above?
