re: Todd Graves worth $7.6 Billion - According to Bloomberg

A simple measure of Wall Street, one that is actually listed along with the vitals on the ticker, is price to earnings ratio. Its listed because it it one of the primary measures of the worth of the company. In the last 10 years, for all companies on S&P that average has been 20 times ebitda (earnings before taxes, amortization, and depreciation).

When a company goes public the striking price at the offering is usually set so buyers taking the early risk get a bump of around 50%. So lets do the math shall we.....

20 times earnings of 647 =12,940 divided by 1.5 (expected premium you will give away)=8,620 times the 90% he owns 7,760 billion (probably a little less since they said "approximately" 90%) And voila you have their evaluation.
