These forward-looking statementsare subject to a number of risks, uncertainties and assumptions, including those described in Part II, Item1A, “RiskFactors” in this Quarterly Report. Readers are urged to carefully review and consider the various disclosures made in thisQuarterly Report and in other documents we file from time to time with the Securities and Exchange Commission, whichwe refer to as the SEC, that disclose risks and uncertainties that may affect our business. Moreover, we operate in a verycompetitive and rapidly changing environment. New risks emerge from time to time. It is not possible for us to predict allrisks, nor can we assess the impact of all factors on our business or the extent to which any factor, or combination offactors, may cause actual results to differ materially from those contained in any forward-looking statements we maymake. In light of these risks, uncertainties, and assumptions, the future events and circumstances discussed in thisQuarterly Report may not occur and actual results could differ materially
