Forward-looking statements give our current 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. You can find many (but not all) of these statements by the use of words such as "approximates," "believes," "hopes," “expects," "anticipates," "estimates," "projects," "intends," "plans," "will," "would," "should," "could," "may" or other similar expressions in this presentation. These statements are likely to address our growth strategy, financial results and product and development programs. You must carefully consider any such statements and should understand that many factors could cause actual results to differ from our forward-looking statements. These factors may include inaccurate assumptions and a broad variety of other risks and uncertainties, including some known and some that are not. No forward-looking statement can be guaranteed and actual future results may vary materially. Factors that could cause actual results to differ from those discussed in the forward-looking statements include, but are not limited to assumptions about our future financial and operating results, including revenue, income, expenditures, cash balances, and other financial items; our ability to execute our growth and expansion plan, including our ability to meet our goals; current and future economic and political conditions; our ability to continue to operate through the jurisdiction in which our subsidiaries operate; our capital requirements and our ability to raise any additional financing which we may require: our ability to attract customers and further enhance our brand awareness; our ability to hire and retain qualified management personnel and key employees in order to enable us to develop our business; and other assumptions described in this presentation underlying or relating to any forward-looking statements. We describe certain material risks, uncertainties and assumptions that could affect our business, including our financial condition and results of operations, under “Risk Factors“. We base our forward-looking statements on our management's beliefs and assumptions based on information available to our management at the time the statements are made. We caution you that actual outcomes and results may, and are likely to, differ materially from what is expressed, implied, or forecast by our forward-looking statements. Accordingly, you should be careful about relying on any forward-looking statements. Except as required under the federal securities laws, we do not have any intention or obligation to update publicly any forward-looking statements after the distribution of this presentation, whether as a result of new information, future events, changes in assumptions, or otherwise.
