Forward-Looking Statements

This Annual Review contains forward-looking statements that the Company expects, believes, or anticipates will or may occur in the future. The Company’s estimates or forward-looking statements are mainly based on its current expectations and estimates of future events and trends, which affect or may affect its business and operations. Although the Company believes that these estimates and forward-looking statements are based upon reasonable assumptions, they are subject to several risks and uncertainties and are made in light of information currently available to the Company. Such statements are subject to a number of assumptions, risks and uncertainties, many of which are beyond the control of the Company, which may cause actual results to differ materially from those implied or expressed by the forward-looking statements. Further information on such assumptions, risks and uncertainties is available with the 10-K and the Company’s other filings with the Securities and Exchange Commission.
