Three NRI CEOs who took their companies way ahead are on Fortune's Business person of the Year list. They are Microsoft CEO Satya Nadella at 38th rank, Mastercard CEO Ajay Banga at 28th rank and Harman International Chairman Dinesh Paliwal at 42nd. The three have been named among 50 global corporate heads on the list that is topped by Google CEO Larry Page, all of whom kept a steady hand on the tiller and took their companies ahead in a year that has seen tumult from volatile markets, viral outbreaks, and a striking return to Cold War politics. On Nadella, Fortune said he introduced a humbler, leaner and hipper Microsoft in his first year as CEO, and initiated a complete strategy overhaul at the software giant. On Banga, Fortune said MasterCard and Banga could benefit from increased transactions using mobile phones, as the company continues its efforts to expand in China and other parts of Asia. Paliwal has been leading Harman since 2007 and overseen ClariFi technology, as strong demand from Ferrari, BMW, Audi and Chrysler turned Harman into a Wall Street favourite. Among others on the list are Apple CEO Tim Cook, Walt Disney CEO Bob Iger, Alibaba Founder Jack Ma, Facebook Founder Mark Zuckerberg, Tesla CEO Elon Musk, Amazon CEO Jeff Bezos, Berkshire Hathaway Chairman and CEO Warren Buffet and Starbucks CEO Howard Schultz.
