WASHINGTON (MarketWatch) -- Nasdaq OMX Group /zigman2/quotes/205547889/composite NDAQ +1.88% and the IntercontinentalExchange /zigman2/quotes/209108507/composite ICE +2.66% late Tuesday encouraged investors in NYSE Euronext to press the firm's directors to meet with them. "Taking this small step would create no commitment and would reassure NYSE Euronext's stockholders that a thorough review process has been undertaken," the firms said as they outlined an investor presentation on their joint bid for the operator of the New York Stock Exchange, Euronext and Liffe exchanges. The NYSE board is recommending a rival offer from the Deutsche Boerse /zigman2/quotes/205502669/delayed DE:DB1 -0.53% . Nasdaq and ICE said there is a history of NYSE Euronext and Deutsche Boerse failing to deliver promised synergy estimates in their past transactions. Nasdaq added it's responding to a second request for information in connection with the Hart-Scott-Rodino antitrust review.
