As actual results could vary significantly from the forward-looking information, you should not put undue reliance on forward-looking information and should not use future-oriented information or financial outlooks for anything other than their intended purpose. We do not update our forward-looking statements due to new information or future events, unless we are required to by law. You can read more about these factors and others in the MD&A in our most recent Quarterly Report to Shareholders and in other reports we have filed with Canadian securities regulators and the SEC, induding the MD&A in our most recent Annual Report.
