NEW YORK (BLOOMBERG) - Tycoon Bill Gates has made his largest gift since the turn of the century, giving away Microsoft Corp shares that accounted for 5 per cent of his fortune, the world's biggest.
The billionaire donated 64 million of the software maker's shares valued at US$4.6 billion (S$6.26 billion) on June 6, according to a Securities & Exchange Commission filing released on Monday (Aug 14).
While the recipient of the gift was not specified, Mr Gates has made the majority of his donations to the Bill & Melinda Gates Foundation, the charity he and his wife use to direct their philanthropic efforts.
It is the largest gift of Microsoft shares that Mr Gates has made since 2000. The 61-year-old gave away US$16 billion worth of Microsoft shares in 1999 and US$5.1 billion a year later, according to calculations by Bloomberg.
Spokesmen for Microsoft and Mr Gates did not immediately respond to requests for comment.
Bill and Melinda Gates have given away about US$35 billion of stock and cash since 1994, based on the value of the shares at the time of gifts, according to a review of two decades' worth of Gates Foundation tax returns, annual reports and regulatory filings.
Mr Gates created the Giving Pledge in 2010 with billionaire investor Warren Buffett, and the pair have been joined by 168 others who have promised to give the majority of their wealth to charity.
Mr Gates has probably directed more than 700 million shares of Microsoft into the foundation, adjusting for stock splits. Those would be worth about US$50 billion today had he held on to them. The June gift represents 38 per cent of his holdings in the company and is the latest in a long line of Microsoft share disposals that have whittled his stake down from 24 per cent in 1996 to 1.3 per cent today.
Mr Gates remains the richest person on earth after the donation, with a fortune the Bloomberg Billionaires Index values at US$86.1 billion.
The drop once again puts Amazon.com's Jeff Bezos close to the top spot. Mr Bezos, whose fortune has risen 30 per cent since Jan 1, briefly leapfrogged Mr Gates to become the world's richest person based on intraday prices last month.
