Gains for women CEOs

Marillyn Hewson, chairman and chief executive of Lockheed Martin, tops the 22nd annual list of the 50 most powerful women in business, said Fortune. The magazine considered four criteria: “the size and importance of the woman’s business in the global economy, the health and direction of the business, the arc of the woman’s career (résumé and runway ahead), and social and cultural influence.” Hewson, who has led Lockheed since 2013, increased the defense contractor’s sales despite some hurdles, such as the U.S. nixing Turkey’s plans to buy F-35 fighter jets. Though 36 Fortune 500 companies—a record number—now have female CEOs, there are still gaps. There’s never been a woman at the head of major U.S. bank, and “women of color remain depressingly rare in the highest of corner offices.”
