Shareholder rights firm Robbins Umeda LLP announced that it is investigating possible breaches of fiduciary duty and other violations of the law by certain officers and directors at Zynga Inc. Robbins Umeda LLP is investigating whether directors of Zynga breached their fiduciary duties to the Company and its shareholders by acting in its own interests with regard to its initial public offering (IPO) and secondary offering, rather than in the best interests of the Company. Pursuant to the Company's IPO Prospectus filed with the U.S. Securities and Exchange Commission (SEC) on December 16, 2011, Zynga's officers and directors agreed to certain lock-up provisions restricting their sale of Zynga common stock until May 28, 2012. On March 14, 2012, Zynga filed a Form S-1 Registration Statement and Prospectus with the SEC in connection with its secondary offering of 49,414,526 shares of Zynga's Class A common stock for certain insider shareholders. On March 23, 2012, before the secondary offering was completed, Zynga filed an Amendment to Form S-1 with the SEC, authorizing the secondary offering of 42,969,153 shares of Class A common stock and waiving the lock-up restrictions that previously restricted Zynga insiders from selling their common stock until May 28, 2012. The secondary offering was completed on April 3, 2012.
