This Current Report on Form 8-K contains "forward-looking statements." Statements that are predictive in nature, that depend upon or refer to future events or conditions, or that include words such as "expects," "anticipates," "intends," "plans," "believes," "estimates," "projects," "forecasts," "may," "should" and similar expressions are forward-looking statements. These statements are not historical facts but instead represent only the Company's belief regarding future results, many of which, by their nature are inherently uncertain and outside of the Company's control. Actual results may differ, possibly materially, from those anticipated in these forward-looking statements. For a discussion of some of the risks and important factors that could affect future results, see the discussion in the Company's Annual Report on Form 10-K, under the heading "Risk Factors."
