39 Long-Term Goals* 1 These goals are forward‐looking, are subject to significant business, economic, regulatory, competitive, and other uncertainties and contingencies, many of which are beyond the control of the Company and its management, and are based upon assumptions with respect to future decisions, which are subject to change. Actual results will vary and those variations may be material. For discussion of some of the important factors that could cause these variations, please consult the “Risk Factors” section in our filings with the Securities and Exchange Commission from time to time, including our Form 10-K for the year ended December 31, 2015.
