Moguls Ronald Perelman, Oleg Deripaska and Tadashi Yanai can add another accomplishment to their financial resumes — the Bloomberg Billionaires Index.

The billionaires were some of the 60 added to the list last week. We now rank the world’s 100 richest people by net worth daily on the Bloomberg Professional service. The index includes profile pages on each individual featuring a transparent analysis of their fortune.

Each net worth figure is updated every business day at 5:30 p.m. in New York. Since the beginning of the year, the 100 billionaires have gained a combined $221 billion. The combined wealth of the index is $1.9 trillion.

In the past 13 months, Bloomberg News has published profiles on more than 30 billionaires who have never appeared on an international wealth ranking. Among them: Dirce Camargo, Brazil’s third-richest person, and Elaine Marshall, America’s fourth-richest woman.
