MORE FOR THE PUBLIC: Zynga's CEO and other insiders plan to sell 43 million shares of stock in a public offering that will boost the amount of stock available for general trading by 35 percent.
THE REASON: This is being done to avoid a drop in its stock price. Early investors typically must wait about six months after an IPO to sell off parts of their stakes, but if everyone flooded the market then, it can drive down the stock price.
OWNERSHIP: Founder Mark Pincus will still control about 35 percent of the company.
