UPDATE: BGC fires back with GFI counteroffer within hours

BGC Partners has retaliated within hours of CME Group announcing an increased tender offer for GFI Group at $5.60 per share, offering a non-contingent $5.75 per share offer that can increase up to $5.85 should the tender offer be accepted by the extended 29 January 2015 deadline. This price escalation represents the newest development in a nearly eight-month bidding war for the firm.
