The Private Securities Litigation Reform Act of 1995 provides safe harbor protections for forward-looking statements in order to encourage companies to provide prospective information about their business. Forward-looking statements include statements concerning plans, objectives, goals, strategies, future events or performance, and underlying assumptions and other statements, which are other than statements of historical facts. The Company desires to take advantage of the safe harbor provisions of the Private Securities Litigation Reform Act of 1995 and is including this cautionary statement in connection with this safe harbor legislation. The words "believe," "except," "anticipate," "intends," "estimate," "forecast," "project," "plan," "potential," "will," "may," "should," "expect" "pending and similar expressions identify forward-looking statements. The forward-looking statements in this press release are based upon various assumptions, many of which are based, in turn, upon further assumptions, including without limitation, our management's examination of historical operating trends, data contained in our records and other data available from third parties. Although we believe that these assumptions were reasonable when made, because these assumptions are inherently subject to significant uncertainties and contingencies which are difficult or impossible to predict and are beyond our control, we cannot assure you that we will achieve or accomplish these expectations, beliefs or projections. In addition to these important factors, other important factors that, in our view, could cause actual results to differ materially from those discussed in the forward-looking statements include future operating or financial results; pending or recent acquisitions, business strategy and expected capital spending or operating expenses, including drydocking and insurance costs; general market conditions and trends, including charter rates, vessel values, and factors affecting vessel supply and demand; our ability to obtain additional financing; our financial condition and liquidity, including our ability to obtain financing in the future to fund capital expenditures, acquisitions and other general corporate activities; our expectations about the availability of vessels to purchase, the time that it may take to construct new vessels, or vessels' useful lives; our dependence upon the abilities and efforts of our management team; changes in governmental rules and regulations or actions taken by regulatory authorities; adverse weather conditions that can affect production of the goods we transport and navigability of the river system; the highly competitive nature of the oceangoing transportation industry; the loss of one or more key customers; fluctuations in foreign exchange rates and devaluations; potential liability from future litigation; and other factors. Please see our filings with the Securities and Exchange Commission for a more complete discussion of these and other risks and uncertainties.
