Nasdaq OMX Group will pursue its bid for crosstown rival NYSE Euronext to the “endgame” and is willing to battle for up to another year, its chief executive said. Nasdaq’s Bob Greifeld added yesterday that he and partner IntercontinentalExchange could put a “fully reflective” offer on the table if the Big Board parent reveals its detailed financial records to them.

Earlier this year the NYSE agreed to be acquired by Germany’s Deutsche Boerse for $9.8 billion.
