Bill Gates' net worth was recalculated by Bloomberg to reflect recent philanthropic giving, causing a 30% decrease in his wealth, placing him in 12th position on the rich list.
Gates now ranks behind his former assistant and successor, Steve Ballmer, who is in fifth place with a net worth of $172 billion.
Gates estimated his fortune at $108 billion in a blog post and pledged to donate most of it through the Gates Foundation over the next 20 years.
Despite the decrease, Gates has gifted $60 billion to the Gates Foundation, with most of his wealth now held by Cascade Investment, while Ballmer's success is attributed to his early equity stake in Microsoft.
