Finally details on much talked about Facebook IPO are here. The Business Insider reports that social networking giant Facebook just filed an amended S-1, which indicates that the company intends to make available 337 million shares at an expected IPO price between $28 and $35. As per the report, Facebook is selling 180 million of the shares, allowing the social networking giant to raise between $4.9 billion and $6.3 billion.

Other shareholders, including CEO Mark Zuckerberg, are selling the remaining 157 million shares, reports Business Insider.

According to Business Insider Reporter Matt Rosoff, Facebook has also allotted an additional 50 million shares in case of higher-than-expected demand. In total, “Facebook will have 2.14 billion shares outstanding, including both class A stock (the kind that's going on sale and has one vote per share) and class B stock (reserved for Mark Zuckerberg and other insiders, with 10 votes per share, allowing Zuck to keep voting control of the company).”

That means, as per the report, Facebook is seeking IPO that is worth between $60 billion and $75 billion. However, it is significantly lower than the Wall Street Journal reported on Wednesday, wrote Rosoff. In fact, “it is lot lower than the $100 billion figure that was being floated around earlier this year.”

Nevertheless, media reports agree with lower valuation because Facebook's revenue growth has been decelerating lately. The report quotes Josh Constine of TechCrunch, saying, “Facebook showed a quarter-to-quarter decline in revenue between the end of 2011 and the first quarter of 2012 -- that's normal for larger companies, but Google didn't show a similar kind of decline until it was showing sales of about $20 billion per year.”
