This annual report contains forward-looking statements. We may also make written or oral forward-looking statements in our annual report to shareholders, in our offering circulars and prospectuses, in press releases and other written materials, and in oral statements made by our officers, directors, or employees. These statements are not historical facts and are based on management’s current view and estimates of future economic circumstances, industry conditions, company performance, and financial results. Forward-looking statements can be identified by the fact that they do not relate only to historical or current facts and may be accompanied by words such as “aim,” “anticipate,” “believe,” “plan,” “could,” “would,” “should,” “estimate,” “expect,” “forecast,” “future,” “guidance,” “intend,” “may,” “will,” “possible,” “potential,” “predict,” “project” or similar words, phrases or expressions, although the absence of any such words or expressions does not mean that a particular statement is not a forward-looking statement. Forward-looking statements speak only as of the date they are made, and we undertake no obligation to update publicly any of them in light of new information or future events.

Forward-looking statements involve only the current view of management and are subject to a number of inherent risks and uncertainties.
