Cautionary Note Regarding Forward-Looking Statements

This Form 8-K includes “forward-looking statements” within the meaning of the safe harbor provisions of the U.S. Private Securities Litigation Reform Act of 1995. Forward-looking statements are not historical facts, but instead represent only the Company’s beliefs regarding future events, many of which, by their nature, are inherently uncertain and outside the Company’s control. It is possible that the Company’s actual results and financial condition may differ, possibly materially, from the anticipated results and financial condition indicated in these forward-looking statements. For a discussion of some of the risks and important factors that could affect the Company’s future results and financial condition, see “Risk Factors” in Part I, Item 1A of the Company’s Annual Report on Form 10-K for the year ended September 30, 2017.
