Actual events or results are subject to significant known and unknown risks, uncertainties and other important factors, many of which are beyond the Company's control. It should be understood that it is not possible to predict or identify all such factors. Investors and analysts should not place undue reliance on forward-looking statements. Forward-looking statements speak only as of the date of the document in which they are made. The Company disclaims any obligation or undertaking to provide any updates or revisions to any forward-looking statement to reflect any change in the Company's expectations or any change in events, conditions or circumstances on which the forward-looking statement is based, except as required by law. It is advisable, however, to consult any further disclosures the Company makes on related subjects in its filings with the U.S. Securities and Exchange Commission, including Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q and Current Reports on Form 8-K (if any).
