Important factors that could cause actual results to differ materially from those indicated by forward-looking statements include risks and uncertainties relating to general economic conditions and related uncertainties; the effect of changes in governmental regulations; and any natural disaster, public health crisis or other catastrophic event. Additional important factors that could cause actual results to differ materially from those indicated by such forward-looking statements are set forth in the Company’s most recent annual report on Form 10-K and subsequent quarterly reports on Form 10-Q, which are on file with the SEC and available in the “Investors” section of the Company’s website under the heading “SEC Filings,” and other documents the Company files with the SEC. While the Company may elect to update forward-looking statements at some point in the future, the Company specifically disclaims any obligation to do so, even if estimates change and, therefore, you should not rely on these forward-looking statements as representing the Company’s views as of any date subsequent to the date of this Current Report on Form 8-K.
