Bill Gates is back on top as the world's richest person, according to Forbes magazine's latest ranking of billionaires.

Microsoft founder Gates took the crown from Carlos Slim Helu, who had been the world's richest for the previous four years. Investing guru Warren Buffett is No. 4.

The magazine pegs Gates' net worth at $76 billion. That's up from $67 billion in 2013.

Slim, a Mexico telecom titan, is close behind at $72 billion. He lost $1 billion from last year.

Third richest is Amancio Ortega of Spain, founder of the Zara clothing retailer, with a net worth of $64 billion.

Next is Buffett. The "Oracle of Omaha" has $58.2 billion, Forbes says.
