Such forward-looking statements only speak as of the date of the presentation and the company assumes no obligation to update the information included in the presentation. Such forward-looking statements include information concerning our possible or assumed future results of operations, including descriptions of our business strategy. These statements often include words such as “believe,” “expect,” “anticipate,” “intend,” “plan,” “estimate” or similar expressions. These statements are not guarantees of performance or results and they involve risks, uncertainties and assumptions , including the risk of continued delay in the completion of our financial statements and the consequences thereof, the availability of funds, either through cash on hand or the company’s other liquidity sources, to repay any amounts due should any of the company’s debt become accelerated, and decisions by suppliers and other vendors to restrict or eliminate customary trade and other credit terms for the company’s future orders and other services, which would require the company to pay cash and which could have a material adverse effect on the company’s liquidity position and financial condition. Although we believe that these forward-looking statements are based on reasonable assumptions, there are many factors that could affect our actual financial results or results of operations and could cause actual results to differ materially from those in the forward-looking statements.
