As we learn more from our data analysis, we will provide additional information on our plans for OMS103HP.

Nasdaq OMX Group Inc. (NDAQ) stock fell 4.22 percent to $24.75 in the pre-market trading, as it and IntercontinentalExchange (ICE) made a joint proposal to acquire NYSE Euronext (NYX) for $42.50 in cash and stock per NYSE Euronext share, or about $11.3 billion. NYSE Euronext stockholders would receive $14.24 in cash, plus 0.4069 shares of NASDAQ OMX common stock and 0.1436 shares of ICE common stock for each NYSE Euronext share.

NASDAQ OMX and ICE would finance the cash portion of the acquisition purchase price through cash on hand and a combined $3.8 billion financing commitment.

As part of the proposal, ICE would purchase NYSE Euronext's derivatives businesses, and NASDAQ OMX would retain NYSE Euronext's remaining businesses, including the NYSE Euronext stock exchanges in New York, Paris, Brussels, Amsterdam and Lisbon, as well as the U.S. options business. ICE and NASDAQ OMX will continue to operate as separate businesses throughout the proposed transaction, as well as after its completion.

Further, a combined NASDAQ OMX/NYSE Euronext would provide accretion to stockholders 12-18 months following the close of the transaction and double digit accretion soon after the 12-18 month period. It would also deliver strong pro forma cash flow generation to invest in the business and service debt. ICE's acquisition would also be solidly accretive to ICE stockholders in year two and would leave ICE with substantial financial flexibility.
