Words such as “anticipate”, “estimate”, “expect”, “project”, “plan”, “intend”, “believe”, “may”, “might”, “will”, “should”, “care have”, “likely” and similar expressions are used to identify forward-looking statements. These forward-looking statements are based on the Company’s current beliefs, assumptions and expectations regarding future events, which in turn are based on information currently available to the Company. By their nature, forward-looking statements address matters that are subject to risks and uncertainties. A variety of factors could cause actual events and results to differ materially from those expressed in or contemplated by the forward- looking statements. These factors include, without limitation, the Company’s ability to respond in a timely and satisfactory matter to the inquiries by Nasdaq, the Company’s ability to become current with its reports with the SEC, and the risk that the completion and filing of the Form 10-K will take longer than expected. For additional information about factors that could cause actual results to differ materially from those described in the forward-looking statements, please refer to the Company’s filings with the SEC, including the risk factors contained in its most recent Annual Report on Form 10-K and the Company’s other subsequent filings with the SEC. The Company undertakes no obligation to publicly update or revise any forward-looking statement, whether as a result of new information, future events or otherwise, except to the extent required by applicable laws.
