2. 2000 – 2005 US Cat Losses

3. 2005 Hurricane Losses Impact on Marine and Offshore Energy  Offshore Energy – Katrina RMS estimates between $2bn and $5bn Eqecat expects a loss ranging from $5bn to $8bn – Rita RMS estimates between $1bn and $2bn  Yacht – Katrina Insurance losses range from $300M to $400M. (Boat Owners Association of The United States- Oct 12, 2005)  Hurricane Katrina also destroyed an estimated 75% of the marinas along 150 miles of the Gulf Coast

16. Catastrophe Modeling Vendors Applied Insurance Research (AIR), EQECAT or Risk Management Solutions (RMS)  valuable knowledge inputs to identify, understand and manage risk

17. Modeled Perils  hurricane – wind – loss amplification/demand surge – storm surge  earthquake – shake – fire following – sprinkler leakage – loss amplification/demand surge  other wind  winter storm  terrorism  flood (Europe)  pandemics

18. Modeled Lines of Business  Personal lines property  Commercial lines property  Industrial property  Builders Risk  Auto Physical Damage  Workers Compensation  Lives at risk – Accident and Health  Marine (partially*) Marine lines Fixed Properties (marinas) - handle well Contents (warehouse cargo) - can handle with adjustments Oil Rigs - modeling capabilities available Mobile Property (cargo, floaters) - capabilities exist but are limited Yachts - capabilities in the RMS May 2006 release Commercial Hull (?)

19. Modeled Coverage Parts  Fixed Property – completed structures – structures under construction (e.g. shipbuilders risk) – machinery & equipment – piers / wharves – offshore platforms  Personal Property – contents – stock – electronic Data Processing equipment  Mobile Property – cargo – floaters including contractors equipment (though generally difficult to include) – personal yachts  Time Element

22. Yacht Modeling Capabilities X RMS RiskLink May 2006 release

23. RMS Construction Classification Update RiskLink version 6.0 (May, 2006)  Seven New RMS Yacht Classes (length and power) – Boats, inside a Building (Marina) - Precast Reinforced Concrete with Concrete Roof (RMS Code 54) – Boats, Moored, Less than 26 ft, Motor - (RMS Code 55) – Boats, Moored, Less than 26 ft, Sail – (RMS Code 56) – Boats, Moored, 26-60 ft, Motor - (RMS Code 57) – Boats, Moored, 26-60 ft, Sail (RMS Code 58) – Boats, Moored, Greater 60 ft, Motor (RMS Code 59) – Boats, Moored, Greater 60 ft, Sail (RMS Code 60)

24. Offshore Energy Modeling/Databases  RMS currently has offshore modeling capabilities – Version 6.0 Changes new construction classes new year built ranges new occupancy classes includes Contingent Business Interruption, Operators Extra Expense new loss amplification factors specific to offshore platforms  EQE to release offshore energy model  ERAS - database program used by many energy clients for capturing exposure information by platform – Exposure management only, no damage estimates or simulations of events.

25. Outlook  Role of Actuaries and Catastrophe Modelers continues to grow in the Marine renewal process.  Models will continue to be valuable as one of many information inputs… – but extremely dangerous if used as the only information input  Models have improved risk quantification significantly… – but can mislead if users do not understand shortcomings  Applications can create significant marketplace advantages… – but inappropriate applications can create hidden dangers  Models continue the tradition of innovation and progress… – but models are “not" perfect and need to improve
