What exactly is covered... where... and how? F Example Hurricane Charley Aug 2004 Sums insured Cover limits Deductibles Exclusions etc. Page 23 Nat Cat modelling: The sophisticated way - simulation Probabilistic Events These artificial events never occurred in history, but they are physically possible and there is no reason why they should not happen one day.

Page 27 Cautionary note on forward-looking statements Certain statements and illustrations contained herein are forward-looking. These statements and illustrations provide current expectations of future events based on certain assumptions and include any statement that does not directly relate to a historical fact or current fact. Forward-looking statements typically are identified by words or phrases such as "anticipate", "assume", "believe", "continue", "estimate", "expect", "foresee", "intend", "may increase" and "may fluctuate" and similar expressions or by future or conditional verbs such as "will", "should", "would" and "could". These forward-looking statements involve known and unknown risks, uncertainties and other factors, which may cause Swiss Re's actual results, performance, achievements or prospects to be materially different from any future results, performance, achievements or prospects expressed or implied by such statements. Such factors include, among others: the impact of significant investments, acquisitions or dispositions, and any delays, unexpected costs or other issues experienced in connection with any such transactions, including, in the case of acquisitions, issues arising in connection with integrating acquired operations; cyclicality of the reinsurance industry; changes in general economic conditions, particularly in our core markets; uncertainties in estimating reserves; the performance of financial markets; expected changes in our investment results as a result of the changed composition of our invested assets or changes in our investment policy; the frequency, severity and development of insured claim events; acts of terrorism and acts of war; mortality and morbidity experience; policy renewal and lapse rates; changes in rating agency policies or practices; the lowering or withdrawal of one or more of the financial strength or credit ratings of one or more of our subsidiaries; changes in levels of interest rates; political risks in the countries in which we operate or in which we insure risks; extraordinary events affecting our clients, such as bankruptcies and liquidations; risks associated with implementing our business strategies; changes in currency exchange rates; changes in laws and regulations, including changes in accounting standards and taxation requirements; and changes in competitive pressures. These factors are not exhaustive. We operate in a continually changing environment and new risks emerge continually. Readers are cautioned not to place undue reliance on forward-looking statements. We undertake no obligation to publicly revise or update any forward-looking statements, whether as a result of new information, future events or otherwise. Page 28 14
