Forward-looking statements

Matters discussed in this press release may contain forward-looking statements. Forward-looking statements are all statements that do not relate to historical facts and events, as well as statements relating to the future which, for example, contain expressions such as “anticipates”, “intends”, “may”, “will”, “should”, “estimates”, “believes”, “could”, “plans”, “continues”, “potential”, “estimates”, “forecasts”, “known” or similar expressions. In particular, these statements relate to future results, financial position, cash flows, plans and expectations regarding the company’s operations and management, future growth and profitability, as well as the general economic and regulatory environment and other circumstances affecting the company, many of which are in turn based on further assumptions, such as the absence of changes in existing political, legal, tax, market or economic conditions or in applicable laws (including, but not limited to, accounting principles, accounting methods and tax policies), which, individually or together, may be material to the company’s results or its ability to conduct its operations. Although the Company considers that these assumptions were reasonable when they were made, they are by their nature subject to significant known and unknown risks, uncertainties, contingencies and other important factors that are difficult or impossible to predict and that may be beyond the Company’s control. Such risks, uncertainties, contingencies and other material factors may cause actual events to differ materially from the expectations expressed or implied in such forward-looking statements. Prospective investors should therefore not place undue reliance on the forward-looking information contained herein, and prospective investors are strongly recommended to read those sections of the information document that contain a more detailed description of factors that may affect the Company’s business and the market in which the Company operates. The information, opinions and forward-looking statements in this press release are valid only as at the date of this press release and may be subject to change without notice.
