However, the absence of these words or similar expressions does not mean that a statement is not forward-looking. Forward-looking statements are not historical facts, but instead represent only our beliefs regarding future events, many of which are inherently uncertain and involve significant known and unknown risks and uncertainties (many of which are beyond the control of the Company) that could cause our actual results and financial condition to differ materially from the anticipated results and financial condition indicated in such forward-looking statements. These risks and uncertainties include, but are not limited to, the risks and uncertainties described in Item 1A (“Risk Factors”) of our Annual Report on Form 10-K for the most recently completed fiscal year, as well as those described from time to time in our other reports and filings with the Securities and Exchange Commission.

In accordance with the safe harbor provisions of the Private Securities Litigation Reform Act of 1995, the Company has included in its filings with the Securities and Exchange Commission cautionary language identifying important factors (but not necessarily all the important factors) that could cause actual results to differ materially from those expressed in any forward-looking statement made by the Company.

You should not place undue reliance on these forward-looking statements, which speak only as of the date of this press release. The Company does not intend, and expressly disclaims any obligation, to update or alter its forward-looking statements (or associated cautionary language), whether as a result of new information, future events, or otherwise, after the date of this press release, except as required by applicable law.
