Cautionary Language Regarding Forward-Looking Statements

Materials in this website may contain information that includes or is based upon forward-looking statements within the meaning of the Securities Litigation Reform Act of 1995. Forward-looking statements give our expectations or forecasts of future events. You can identify these statements by the fact that they do not relate strictly to historical or current facts. Forward-looking statements typically are identified by the use of terms such as words such as “may,” “will,” “should,” “might,” “expect,” “anticipate,” “estimate,” “plan,” “intend,” “goal,” “project,” “strategy,” “future,” and similar words, although some forward-looking statements are expressed differently. In particular, these include statements relating to future actions, prospective products, future performance or results, the outcome of contingencies such as legal proceedings, and future financial results.

Any or all of our forward-looking statements here or in other publications may turn out to be wrong. They can be affected by inaccurate assumptions or by known or unknown risks and uncertainties. Many such factors will be important in determining our actual future results. Consequently, no forward-looking statement can be guaranteed. Our actual results may vary materially.

We undertake no obligation to correct or update any forward-looking statements, whether as a result of new information, future events or otherwise, except as required by law. You are advised, however, to consult any further disclosures we make on related subjects in our reports to the SEC. In particular, you should read the discussion in the section entitled “A Warning About Forward-Looking Statements” in our most recent 10-K report to the SEC, as it may be updated in our subsequent 10-Q and 8-K reports. That discussion covers certain risks, uncertainties and possibly inaccurate assumptions that could cause our actual results to differ materially from expected and historical results. Other factors besides those listed there could also adversely affect the Company. That discussion is provided as permitted by the Private Securities Litigation Reform Act of 1995.
