With the resignation of PepsiCo CEO Indra Nooyi, there will be only 23 female CEOs of Fortune 500 companies, down from 32 in 2017, according to MarketWatch.
Though high-profile female executives such as Meg Whitman of Hewlett-Packard and Denise Morrison of Campbell Soup have stepped down in the last year, when Ms. Nooyi became CEO of PepsiCo in October 2006 there were only 11 women leading Fortune 500 companies.
"It concerns me in that we can actually count how many [female CEOs] there are, as opposed to saying there are hundreds," Ms. Nooyi told Fortune.
Only 5.1 percent of CEOs of companies in the S&P Composite 1500 index are women, according to a study from the Pew Research Center.
