Bill Gates tops rich list

For the first time, it takes more than $1 billion to earn a spot on Forbes magazine’s list of the 400 richest Americans. The minimum net worth for inclusion in this year’s rankings released Thursday was $1.3 billion, up $300 million from last year.

The new threshold meant 82 of America’s billionaires didn’t make the cut.

Collectively, the people who made the rankings released Thursday are worth $1.54 trillion, compared with $1.25 trillion last year.

The very top of the list was unchanged: Microsoft Corp. founder Bill Gates led the list for the 14th straight year, this time with a net worth estimated at $59 billion. He was followed by Warren Buffett of Berkshire Hathaway Inc. in second place with an estimated $52 billion and casino mogul Sheldon Adelson, No. 3 with an estimated worth of $28 billion.

Larry Ellison of Oracle Corp. maintained his ranking at No. 4, with an estimated net worth of $26 billion.

Joining the top 10 of the country’s richest for the first time were Google Inc. founders Sergey Brin and Larry Page, who tied for fifth place. The 34-year-old moguls’ wealth has quadrupled since 2004 to an estimated $18.5 billion.
