The IntercontinentalExchange Inc. (ICE) expects to close its acquisition of NYSE Euronext on November 4, the exchanges said Thursday.

ICE and the NYSE announced that they have established a closing date for their previously announced transaction, which is predicated upon the companies receiving the remaining European regulatory approvals prior to that date. The closing may have to be extended if they don’t get those approvals in time.

Earlier this month, the exchanges said that the Chairmen’s Committee of Euronext Regulators have issued a letter indicating that they do not object to the proposed merger. They are still awaiting final approvals from national authorities and regulatory bodies in each of the relevant European jurisdictions in order to complete the transaction.

Along with the deadline to close the deal itself, ICE and the NYSE have also set Oct. 31 as an election deadline for shareholders of NYSE Euronext to chose stock and/or cash for their shares. Although, shares held in nominee name may have an earlier deadline, they note.
