-----------Hold on! Is Mukesh Ambani the richest man alive?
Yes, according to a report by the
Press Trust of India released on Monday, which pegged his wealth at
$63.2 billion (almost Rs 2.49 lakh crore).
However,
some say he is not yet there. “Ambani’s holding in Reliance Petroleum
should not be counted, as he doesn’t hold any share in the company
directly and the price of Reliance Industries already reflects its
investment in Reliance Petroleum,†said an industry source.He
has reportedly just overtaken Carlos Slim of Mexico and Microsoft’s
Bill Gates, whose personal assets are $62.299 billion and $62.290
billion respectively. The calculations take into account Ambani’s
holding in Reliance Industries and Reliance Petroleum through Reliance
Industries, apart from stakes in Reliance Industrial Infrastructure Ltd.
Moreover, Ambani owns around 46 per cent of Reliance Industries out of the 50.98 per cent held by the promoters. That would suggest he is worth close to $50 billion (Rs 1.9 lakh crore). But with the rupee and Sensex soaring, Ambani could soon become the undisputed richest man alive.
