Prior to this week, Zynga's stock valuation has floundered since its own heavily hyped IPO in December. The stock came out behind on its first day of public trading, after the company set an opening valuation of $10. Since then, the stock hadn't shown much signs of life, bottoming out at $7.97 per share in mid-January.

However, as revealed in Facebook's Securities and Exchange Commission filing, Zynga is a significant contributor to the social network's top line. Of the $3.71 billion in revenues Facebook earned in 2011, 12 percent, or about $450 million, came from Zynga's sale of virtual goods.

Zynga products account for seven of the top 10 games on Facebook, according to Currently, Zynga's CityVille, Texas HoldEm Poker, and CastleVille are the top social games on Facebook.
