Facebook just filed an amended S-1 (that all important document that officially announces its public offering plans) with some new financial info. Now included in the charts and graphs is everything you wanted to know about Q1 of 2012 at Facebook (but were afraid to ask). The new SEC filing reveals that revenues are way up at the social network over last year (a whopping 45 percent higher than Q1 of 2011), but down slightly from last quarter (six percent), settling at a more than respectable $1.058 billion. Of the cash it took in, $872 million of it was ad revenue, which is down from Q4 of 2011 ($943 million) but up significantly from Q1 of last year ($731 million). Facebook was even able to slap a per-user amount on its 900 million active monthly members -- $1.21 -- that's the average revenue for each person with an account at the site. Of course, membership has continued to grow, with 532 million stopping by daily, up from 372 million just a year ago. As for that Instagram purchase, it looks like the widely reported $1 billion figure wasn't entirely accurate -- at least not when talking cold, hard cash. Only $300 million was turned over in immediately spendable currency, the rest of the deal involved 23 million shares of common stock. If you're a sucker for financials hit up the source link.
