Nonetheless, we did some digging and reached out to Fortune’s Ellen McGirt and Kristen Bellstrom. They explained that all women listed must have an operational role in a large-scale company. “We have a couple of CFO’s who have outside influence in their companies, but otherwise we really just consider women who are in operating positions.” That is why women like Denise Young-Smith, the VP of Worldwide Human Resources at Apple Inc., didn’t make the list, she said. She added that Channing Dungey, who was appointed last year as president of ABC Entertainment, was also in the running. However, she was not selected because “her business was not quite large enough. We don’t have a lot of women in entertainment and it tends to be because the businesses that they control aren’t as large as some of these Fortune 500 companies,” Bellstrom explained.
