In some cases, you can identify forward-looking statements by words such as “may,” “hope,” “will,” “should,” “expect,” “plan,” “anticipate,” “intend,” “believe,” “estimate,” “predict,” “potential,” “continue,” “could,” “future” or the negative of those terms or other words of similar meaning. You should carefully read forward-looking statements, including statements that contain these words, because they discuss our future expectations or state other “forward-looking” information. Forward-looking statements involve a number of risks and uncertainties. ICE and NYSE Euronext caution readers that any forward-looking statement is not a guarantee of future performance and that actual results could differ materially from those contained in the forward-looking statement. Such forward-looking statements include, but are not limited to, statements about the benefits of the proposed merger involving ICE and NYSE Euronext, including future financial results, ICE’s and NYSE Euronext’s plans, objectives, expectations and intentions, the expected timing of completion of the transaction and other statements that are not historical facts. Important factors that could cause actual results to differ materially from those indicated by such forward-looking statements are set forth in ICE’s and NYSE Euronext’s filings with the U.S. Securities and Exchange Commission (the “SEC”). These risks and uncertainties include, without limitation, the following: the inability to close the merger in a timely manner; the inability to complete the merger due to the failure of NYSE Euronext stockholders to adopt the merger agreement or the failure of ICE stockholders to approve the issuance of ICE common stock in connection with the merger; the failure to satisfy other conditions to completion of the merger, including receipt of required regulatory and other approvals; the failure of the proposed transaction to close for any other reason; the possibility that any of the anticipated benefits of the proposed transaction will not be realized; the risk that integration of NYSE Euronext’s operations with those of ICE will be materially delayed or will be more costly or difficult than expected; the challenges of integrating and retaining key employees; the effect of the announcement of the transaction on ICE’s, NYSE Euronext’s or the combined company’s respective business relationships, operating results and business generally; the possibility that the anticipated synergies and cost savings of the merger will not be realized, or will not be realized within the expected time period; the possibility that the merger may be more expensive to complete than anticipated, including as a result of unexpected factors or events; diversion of management’s attention from ongoing business operations and opportunities; general competitive, economic, political and market conditions and fluctuations; actions taken or conditions imposed by the United States and foreign governments and regulatory authorities; and adverse outcomes of pending or threatened litigation or government investigations. In addition, you should carefully consider the risks and uncertainties and other factors that may affect future results of the combined company described in the section entitled “Risk Factors” in the joint proxy statement/prospectus to be delivered to ICE’s and NYSE Euronext’s respective shareholders, and in ICE’s and NYSE Euronext’s respective filings with the SEC that are available on the SEC’s web site located at www.sec.gov, including the sections entitled “Risk Factors” in ICE’s Form 10−K for the fiscal year ended December 31, 2011, as filed with the SEC on February 8, 2012, and ICE's Quarterly Reports on Form 10-Q for the quarters ended June 30, 2012, as filed with the SEC on August 1, 2012 and September 30, 2012, as filed with the SEC on November 5, 2012, and “Risk Factors” in NYSE Euronext’s Form 10−K for the fiscal year ended December 31, 2011, as filed with the SEC on February 29, 2012.
