This Annual Report on Form 10-K includes market share and industry data that we obtained from industry publications and surveys, reports of governmental agencies and internal company surveys. Industry publications and surveys generally state that the information they contain has been obtained from sources believed to be reliable, but we cannot assure you that this information is accurate or complete. We have not independently verified any of the data from third-party sources nor have we ascertained the underlying economic assumptions relied upon therein. Statements as to our market position are based on the most currently available market data. While we are not aware of any misstatements regarding industry data presented herein, our estimates involve risks and uncertainties and are subject to change based on various factors. Please refer to the “Risk Factors” in Part I, Item 1A of this Annual Report on Form 10-K and our other filings with the SEC.

FORWARD-LOOKING STATEMENTS

This Annual Report on Form 10-K 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 "Business" and "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 Annual 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:

•the loss of our right to exclusively list and trade certain index options and futures products;

•economic, political, and market conditions;

•compliance with legal and regulatory obligations;

•price and new products and services competition and consolidation in our industry;

•decreases in trading or clearing volumes, market data fees, or a shift in the mix of products traded on our exchanges;

•legislative or regulatory changes or changes in tax regimes;

•our ability to protect our systems and communication networks from security vulnerabilities and breaches;

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

•increasing competition by foreign and domestic entities;

•our business and operational dependence on and exposure to risk from third parties;

•factors that impact the quality and integrity of our and other applicable indices;

•our ability to manage our global operations, growth, and strategic acquisitions, wind downs, divestitures, or alliances effectively;

•increases in the cost of the products and services we use;

•our ability to operate our business without violating the intellectual property rights of others and the costs associated with protecting our intellectual property rights;

•our ability to minimize the risks, including our credit, liquidity, market, investment, counterparty, and default risks, associated with operating our clearinghouses;

•our ability to accommodate trading and clearing volume and transaction traffic, including significant increases, without failure or degradation of performance of our systems;

•misconduct by those who use our markets or our products or for whom we clear transactions;

•challenges to our use of open source software code;

•our ability to meet our compliance obligations, including managing our business interests and our regulatory responsibilities;

•the loss of key customers or a significant reduction in trading or clearing volumes by key customers;

•damage to our reputation;

•the ability of our compliance and risk management methods to effectively monitor and manage our risks;

•restrictions imposed by our debt obligations and our ability to make payments on or refinance our debt obligations;

•our ability to maintain an investment grade credit rating;

•impairment of our goodwill, long-lived assets, investments, or intangible assets;

•the accuracy of our estimates and expectations; and

•litigation risks and other liabilities.

For a detailed discussion of these and other factors that might affect our performance, see Part I, Item 1A of this 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.
