According to the source close to the deal, Facebook has selected Morgan Stanley along with four others — Bank of America Merrill Lynch, Goldman Sachs, JP Morgan and Barclay's Capital to handle this IPO. Morgan Stanley will be taking "lead left" role in this supposedly biggest IPO from Silicon Valley. According to International Financing Review, the preliminary target of $5 billion will be increased by many folds in coming few months as a response to the demands of investors. Sources close to this matter disclosed that this might turn out to be defining moment for current web investments. The deal might rise to $10 billion which eventually will make Facebook a social networking empire valued between $75 billion to $100 billion. In fact, $75 billion is definitely an undervaluation compared to previous expectations.
