Facebook IPO: Who is getting rich?

When Facebook lists on the Nasdaq exchange, some of the company’s employees will become instant millionaires, while its founders will be worth billions. How rich they end up will be determined by the price of the stock  on the first day of trading (US$34 to $38) and how those prices move in the days, months and years after that. Based on a market valuation of US$50 to US$104 billion (at the high end), check out how rich Mark Zuckerberg, Bono and others will be when Facebook hits the open market.
