What to expect from Facebook's IPO filing The filing also probably will talk about the company's strategy going forward and detail how the company plans on retaining its users, working with its partners and shoring up ad revenue. Another interesting figure to watch for in the S-1 will be the company's record of hiring. Facebook has invested a lot in talent and is currently expanding, hiring for its new New York engineering office. But, as CNET's Roger Cheng points out, Facebook also has to be wary of the employee turnover that can plague top tech companies. Smart tech talent can often be poached by other companies or feel the urge to strike out on their own ventures. Risk Factors: The risk factors a company lists in its S-1 are often illuminating and can offer insights into the way the company's thinking about policy issues or competitors. Companies tend to be pretty exhaustive with their risk factors in this section. Zynga, for example, listed its reliance on Facebook as a possible risk factor in its IPO filing. It also listed that it's located near an earthquake fault zone. Pandora and Zynga both raised concerns about something that Facebook is also likely to have: privacy legislation. There's been a lot of talk about privacy on the Hill and a renewed crackdown on privacy from the Federal Trade Commission, something that Facebook itself knows all too well. Although its recent settlement with the FTC over privacy concerns probably will help the company in the long run, experts told The Washington Post, Facebook COO Sheryl Sandberg has also been speaking publicly about the possibly limiting effects that privacy legislation could have on innovation. It will also be interesting to see which companies Facebook lists as potential competitors in this section. There's a high probability, of course, that Google will be mentioned in this filing because of its Google+ network. But there are myriad other social, media and competing advertising companies out there that could also be mentioned as potential threats, and it will be interesting to see where Facebook is casting its wary eyes. Don't expect:There are some things you shouldn't expect to see in Facebook's S-1 as well: executive compensation, for example, or the day and price that the company will start trading shares. The Wall Street Journal also reported that it's unlikely that we'll see Facebook reveal which exchange they're planning on being a part of, the tech-focused NASDAQ or the New York Stock Exchange. That also means we might not see a proposed ticker for the company, meaning we'll have to wait to see if the company picks something pedestrian like FCBK or FB, or something more fun, like - as one person on Twitter suggested - POKE.
