Cautionary Statement Concerning Forward-Looking Statements
This report and the documents incorporated by reference herein contain statements which, to the extent they are not recitations of historical fact, constitute forward-looking statements within the meaning of federal securities law. Investors are cautioned that all forward-looking statements involve risks and uncertainties, and are based on assumptions that we believe in good faith are reasonable at the time the statements are made, but which may be materially different from actual results. Investors can identify these statements by the fact that they do not relate only to historic or current facts. The words “may”, “will”, “could”, “should”, “anticipate”, “believe”, “estimate”, “expect”, “forecast”, “intend”, “outlook”, “plan”, “project”, “scheduled” and similar expressions in connection with future events or future operating or financial performance are intended to identify forward-looking statements. Any or all of the Company’s forward-looking statements in this release may turn out to be wrong.
Statements and assumptions on future revenues, income and cash flows, performance, economic trends, the outcome of litigation, regulatory compliance and environmental remediation cost estimates are examples of forward-looking statements. Numerous factors could affect our forward-looking statements and actual performance. In addition, other risks and uncertainties not presently known to us or that we currently consider immaterial could affect the accuracy of our forward-looking statements.
Except as required by law, we undertake no obligation to update any forward-looking statements in order to reflect any event or circumstance that may arise after the date of this report.
Additional information concerning these and other factors can be found in the Company’s filings with the Securities and Exchange Commission, including the Company’s most recent Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q and Current Reports on Form 8-K.
