FORWARD LOOKING STATEMENTS AND RESPONSIBILITY - -------------------------------------------------------------------------------- SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS Certain statements in this presentation constitute "forward-looking statements" within the meaning of the Private Securities Litigation Reform Act of 1995. Carnival Corporation ("CCL") has tried, wherever possible, to identify such statements by using words such as "anticipate," "assume," "believe," "expect," "intend," "plan" and words and terms of similar substance in connection with any discussion of future operating or financial performance. These forward-looking statements, including those which may impact the forecasting of CCL's net revenue yields, booking levels, price, occupancy or business prospects, involve known and unknown risks, uncertainties and other factors, which may cause CCL's actual results, performances or achievements to be materially different from any future results, performances or achievements expressed or implied by such forward-looking statements. Such factors include, among others, the following: general economic and business conditions which may impact levels of disposable income of consumers and the net revenue yields for CCL's cruise products; consumer demand for cruises and other vacation options; other vacation industry competition; effects on consumer demand of armed conflicts, political instability, terrorism, the availability of air service and adverse media publicity; increases in cruise industry and vacation industry capacity; continued availability of attractive port destinations; changes in tax laws and regulations; CCL's ability to implement its shipbuilding program and to continue to expand its business outside the North American market; CCL's ability to attract and retain shipboard crew; changes in foreign currency rates, security expenses, food, fuel, insurance and commodity prices and interest rates; delivery of new ships on schedule and at the contracted prices; weather patterns; unscheduled ship repairs and dry-docking; incidents involving cruise ships; impact of pending or threatened litigation; and changes in laws and regulations applicable to CCL. CCL cautions the reader that these risks may not be exhaustive. CCL operates in a continually changing business environment, and new risks emerge from time to time. CCL cannot predict such risks nor can it assess the impact, if any, of such risks on its business or the extent to which any risk, or combination of risks may cause actual results to differ from those projected in any forward-looking statements. Accordingly, forward-looking statements should not be relied upon as a prediction of actual results. CCL undertakes no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events or otherwise.
