These statements may relate to, among other things, capital expenditures, acquisitions, cost reductions, cash flow, revenues, earnings, market conditions, global economies and operating improvements, and are indicated by words or phrases such as “anticipates,” “estimates,” “plans,” “expects,” “projects,” “forecasts,” “should,” “could,” “will,” “management believes,” “the company believes,” “the company intends,” and similar words or phrases. These statements are subject to inherent uncertainties and risks that could cause actual results to differ materially from those anticipated at the date of this news release.

Additional factors that could cause actual results to differ materially from those reflected in the forward-looking statements include, but are not limited to, the risks discussed in the “Risk Factors” section included in the company’s most recent annual report on Form 10-K filed with the SEC and the other risks discussed in the company’s filings with the SEC.
