New Delhi: The richest people in the world got even richer in 2013, adding $524 billion to their collective net worth, according to the Bloomberg Billionaires Index, a daily ranking of the world's 300 wealthiest individuals. The ranking says the aggregate net worth of the world's top billionaires stood at $3.7 trillion as on December 31.
Bill Gates, the founder and chairman of Microsoft, was the year's biggest gainer. The 58-year-old tycoon's fortune increased by $15.8 billion to $78.5 billion, the index revealed, as shares of Microsoft, the world's largest software maker, rose 40 per cent. Gates' fortunes also benefited from a rally in stock holdings that include the Canadian National Railway, which rose 34 per cent, and a maker of sanitizing products, Ecolab, which rose 45 per cent.
Second in the index is Carlos Slim Helu, the Mexican telecommunications mogul, whose net worth stood at $69.6 billion. But despite his high ranking, Helu was also one of the biggest losers, with his net worth dropping $1.4 billion in the course of last year after Mexico's government tried to reduce the dominance of his América Móvil mobile phone company.
