 Safe Harbor Statement and Non-U.S. GAAP Financial Terms  Statements in this presentation that are not historical are forward-looking statements within the meaning of the safe harbor provisions of the U.S. Private Securities Litigation Reform Act of 1995. 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 the results, level of activity, performance or achievements expressed or implied by the forward-looking statements. These and other risk factors are discussed in the company's filings with the Securities and Exchange Commission (SEC), including those under the heading entitled “Risk Factors" in our Annual Report on Form 10-K for the year ended December 31, 2017. 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 for our management to predict all risks and uncertainties, nor can management 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. Although we believe the expectations reflected in the forward-looking statements are reasonable, we cannot guarantee future results, level of activity, performance or achievements. Moreover, neither we nor any other person assumes responsibility for the accuracy or completeness of any of these forward-looking statements. You should not rely upon forward-looking statements as predictions of future events. Unless otherwise required by applicable laws, we undertake no obligation to update or revise any forward-looking statements, whether as a result of new information or future developments.This presentation contains certain non-U.S. GAAP financial terms that we use in the management of our business, including EBITDA, adjusted EBITDA, adjusted EBITDA margin, free cash flow and adjusted earnings per diluted share. Reconciliations to their nearest U.S. GAAP terms are provided in the Appendix of this presentation.
