Out of the world's 10 wealthiest CEOs, four positions have been grabbed by Indians -- Lakshmi Mittal is ranked at the second place followed by Mukesh Ambani (6th place), Anil Ambani (7th) and Wipro chief Azim Premji (9th).
The list has been topped by Warren Buffet, the Chief Executive of Berkshire Hathaway with a fortune of 52 billion dollars.
Arcelor Mittal chief Lakshmi Mittal has a net worth of 32 billion dollars, while Mukesh Ambani and Anil Ambani have fortunes worth 20.1 billion dollars and 18.2 billion dollars, respectively.
Chief of IT bellweather Wipro Azim Premji has a net worth of 17.1 billion dollars.
However, these net worth figures are not current and have been taken from a list prepared almost a year back for Indian businessmen and from a September list for those from the US.
Forbes said that the list of wealthiest CEOs was prepared after perusing the ranks of the Forbes 400 list of the richest Americans from September and its annual billionaires' list from last March.
"We found the 10 richest CEOs around, some of whom founded their own companies, others who benefited from large inheritances and still others who built their fortunes through other means," the magazine said.
About Mukesh Ambani the Chairman and Managing Director of country's most valued firm Reliance Industries, the magazine said: "Ambani fulfils the duties of CEO at his company, even though he doesn't carry the title."
