This Quarterly Report contains estimates and information concerning our industry, including market position, market size and growth rates of the markets in which we participate, that are based on industry publications and reports. This information involves a number of assumptions and limitations, and you are cautioned not to give undue weight to these estimates. Although we are responsible for all of the disclosure contained in this Quarterly Report and we believe the information from the industry publications and other third-party sources included in this Quarterly Report is reliable, we have not independently verified the accuracy or completeness of the data contained in such sources. Similarly, while we believe our management estimates to be reasonable, they have not been verified by any independent sources. The industry in which we operate is subject to a high degree of uncertainty and risk due to a variety of factors, including those described in the section titled “Risk Factors” in Part II, Item 1A of this Quarterly Report and our other filings with the Securities and Exchange Commission (“SEC”). These and other factors could cause results to differ materially from those expressed in these publications and reports.

SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

This Quarterly Report contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995 that involve a number of risks and uncertainties. You can identify these statements by forward-looking words such as “may,” “might,” “should,” “expect,” “plan,” “anticipate,” “believe,” “estimate,” “predict,” “potential” or “continue,” and the negative of these terms and other comparable terminology. All statements that reflect our expectations, assumptions or projections about the future other than statements of historical fact are forward-looking statements, including statements in “Management’s Discussion and Analysis of Financial Condition and Results of Operations.” These forward-looking statements, which are subject to known and unknown risks, uncertainties, and assumptions about us, may include projections of our future financial performance based on our growth strategies and anticipated trends in our business. These statements are only predictions based on our current expectations and projections about future events. There are important factors that could cause our actual results, level of activity, performance, or achievements to differ materially from those expressed or implied by the forward-looking statements. In particular, you should consider the risks and uncertainties described under “Risk Factors” in this Quarterly Report and other filings with the SEC.

While we believe we have identified material risks, these risks and uncertainties are not exhaustive. Moreover, we operate in a very competitive and rapidly changing environment. New risks and uncertainties emerge from time to time, and it is not possible to predict all risks and uncertainties, nor can we assess the impact of all factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements.

Some factors that could cause actual results to differ include:

•our expectations regarding our operating and financial results and performance, competitive position, including pricing within our industry and our ability to maintain profitability and generate profitable growth over time;

•the sufficiency of our existing capital resources to fund our future operating expenses;

•the timing and success of our new products and product offerings;

•changes to the regulatory environment and compliance with law and regulations;

•our ability to attract trading volume to our exchanges;

•our ability to maintain order flow from our order flow providers;

•revenues from our market data fees and access and capacity fees;

•our dependence on third parties;

•changes in user preferences;

•our ability to attract and retain skilled management and other personnel;

•our ability to minimize the risks, including credit and default risks, associated with operating a clearing house;

•the growth of our business through offering new services and product offerings and acquisitions or strategic alliances;

•our ability to invest in technology and keep up with rapid technological changes affecting our industry;

•the impairment of our goodwill, other intangible assets or investments;

•the efficacy of our risk management methods;

•litigation risks and other liabilities;

•our ability to protect our intellectual property rights and avoid violating the intellectual property rights of others; and

•the impact on our business of global economic, political and financial market events or conditions, including regional conflicts and war.

For a detailed discussion of these and other factors that might affect our performance, see Part II, Item 1A of this Quarterly Report. We do not undertake, and expressly disclaim, any duty to update any forward-looking statement whether as a result of new information, future events or otherwise, except as required by law. We caution you not to place undue reliance on the forward-looking statements, which speak only as of the date of this filing.
