World's Wealthiest Man Says He Doesn't Care About Rank

MEXICO CITY -- Mexican telecom tycoon Carlos Slim, who is estimated by some calculations to be wealthier than Microsoft founder Bill Gates, said Thursday that he did not care whether he was the world's richest person.

"It's water off a duck's back to me," the cigar-smoking Slim told foreign correspondents. "I don't know whether I'm No. 1, No. 20, or No. 2,000. It doesn't matter."

In July, a journalist who tracks the fortunes of wealthy Mexicans said Slim was worth an estimated $67.8 billion and had overtaken Gates as the world's richest person.

Slim hit the No. 1 spot after a recent surge in the share price of his America Movil, Latin America's largest cell phone company, Eduardo Garcia of the online financial publication Sentido Comun said.

Garcia said that made him close to $8.6 billion wealthier than Gates, whose estimated worth was $59.2 billion.

Slim, 67, said Thursday that making sure his job was compatible with his family or personal life was more important than his wealth.

Forbes magazine reported in April that Slim had overtaken U.S. investor Warren Buffett for the No. 2, but it is not scheduled to recalculate Slim's wealth until next year.

Slim, known for his Midas touch in turning struggling businesses into profit-making machines, said this year that he did not calculate his fortune on a regular basis.
