The law firm of Wohl & Fruchter LLP is investigating whether the directors of GFI Group Inc. (NYSE: GFIG) (“GFI”) breached their fiduciary duties to shareholders by approving a merger with CME Group Inc. (NASDAQ: CME) (“CME”). On July 30, 2014, CME and GFI announced that they had entered into an agreement under which CME will acquire all of the shares of GFI for $4.55 per share, payable in CME common stock. Immediately following CME’s acquisition of GFI, a private consortium of GFI management, led by current Executive Chairman Michael Gooch, CEO Colin Heffron and Managing Director Nick Brown, will acquire GFI's wholesale brokerage and clearing businesses, including the Kyte Group, back from CME for $165 million in cash and the assumption, at closing, of approximately $63 million of unvested deferred compensation and other liabilities. Wohl & Fruchter’s investigation concerns whether the approval of the transaction above by the directors of GFI was improperly motivated by conflicts of interest created by CME’s agreement to sell back GFI's wholesale brokerage and clearing businesses to GFI senior management as part of the transaction.
