Forward-looking statements are those statements that reflect our expectations, assumptions or projections about the future and involve a number of risks and uncertainties. These statements are only predictions based on our current expectations and projections about future events. There are important factors that could cause actual results to differ materially from that expressed or implied by the forward-looking statements, including: the loss of our exclusive licenses to list certain index options; decreases in the amount of trading volumes or a shift in the mix of products traded on our exchanges; legislative or regulatory changes affecting the options markets; increasing competition by foreign and domestic entities, including increased competition from new entrants into our markets and consolidation of existing entities; increasing price competition; our ability to maintain access fee revenues; economic, political and market conditions; 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 accommodate increases in trading volume and order transaction traffic without failure or degradation of performance of our systems; our ability to protect our systems and communication networks from security risks, including cyber attacks; our ability to attract and retain skilled management and other personnel; our ability to maintain our growth effectively; our dependence on third party service providers; and the ability of our compliance and risk management methods to effectively monitor and manage our risks.
