"The World's Best CEOs: An Exclusive Barron's List — GM's Mary Barra and Microsoft's Satya Nadella join this year's roster of 30 outstanding corporate leaders":

• "One newcomer this year, Mary Barra at General Motors, who graces our cover this week, exemplified traits that impressed us. Barra slashed the car maker's costs by $4 billion, but GM hasn't cut corners; last year, Chevrolet won the most J.D. Power Initial Quality awards of any automotive brand."
• "Barra also has made an impression in Washington, where she sits on the president's Strategic and Policy Forum of economic advisors. She recently won plaudits from the administration for keeping some manufacturing jobs in Michigan."
• "OTHER CEOS NEW to the list this year are Gary Dickerson at Applied Materials, Stephen Hemsley at UnitedHealth Group, Jen-Hsun 'Jensen' Huang at Nvidia, Phebe Novakovic at General Dynamics, and Martin Sorrell at WPP."
