On Wednesday, Fortune Magazine released its 2017 Fortune 500 list, which ranks major U.S. companies by their fiscal 2016 revenues, and 32 of the companies, or 6.4 percent, were run by female CEOs.
The magazine said that number was the highest proportion yet seen in the 63-year history of the list. Last year, it had just 21 women CEOs on the list, and for the 2014 fiscal year, there were 24.
Roughly a third of the women running companies on the list are new to the job: A startling 11 women were named CEO of companies in 2016 or early 2017 that are on this year's Fortune 500 list, including Vicki Hollub at Occidental Petroleum, Tricia Griffith at the insurer Progressive, Shira Goodman at Staples, Margo Georgiadis at Mattel and Michele Buck at Hershey. At Hertz Global Holdings, Kathryn Marinello was named to the top job late last year, as was Anna Manning at Reinsurance Group of America.
That's a significant jump from one year to the next, and comes at a time when more attention is being paid by investors to the value of diversity in the boardroom. Investors are pushing shareholder proposals that urge companies to add diversity among their top ranks, and financial companies are adding products that let investors bet on companies with more women at the top, as research demonstrates a link between diversity and better performance.
Women run seven of the country's very largest companies, the Fortune 100, including Mary Barra at General Motors, Ginni Rometty at IBM, Indra Nooyi at PepsiCo and Marillyn Hewson at Lockheed Martin.
That may be one reason executive compensation experts say, that the median female CEO, surprisingly, makes more than her male peer. While the explanation for why is unclear -- it could, of course, simply be due to better performance, or companies could pay a "diversity premium" for a female CEO -- the median female CEO made $13.1 million in 2016, compared with $11.4 million for the median male CEO.
