Facebook has finally decided to launch IPO with the price range between $ 28 to mid $ 35. World's largest social networking website will start trading on Nasdaq exchange on May 18, according to S-1 filing from the company

Facebook plans to raise as much as $12 billion in Silicon Valley's largest IPO, dwarfing the coming-out parties of tech companies like Google and granting the world's largest social network a market value close to Amazon.com's.

The company also released video of its road show, set to start on Monday, online. (Click to watch the video.)

Facebook plans to invest heavily in mobile, even if the payoff takes a long time or is uncertain, Chief Financial Officer David Ebersman says in the video. Chief Operating Officer Sheryl Sandberg adds that mobile is a key growth area for the company.

The eight-year-old social network that began as Mark Zuckerberg's Harvard dorm room project priced its initial public offering at between $28 and $35 a share on Thursday, attaining a valuation of as much as $95.9 billion at the high end. Shares are expected to be priced the evening of May 17, with trading beginning on May 18.

If an over-allotment or "greenshoe" option is triggered, the company could end up raising close to $13.6 billion, according to a Thursday prospectus.

Investors are expected to flock to the highly anticipated IPO, though some have voiced concerns about the social network's longer-term growth

Last week, Facebook reported its first quarter-to-quarter revenue slide in at least two years, a sign that the social network's sizzling growth may be cooling just as it prepares to go public. Its stock should begin trading in about a week or two.

Facebook, which plans to list its stock on the Nasdaq under the ticker "FB", will begin meeting with investors on Monday.
