17. © 2003 AIR Worldwide Corporation CONFIDENTIAL Delphi Method Provides Sound Basis for Frequency Estimates q Developed during 1940s at the RAND Corporation to study the "broad subject of inter-continental warfare other than surface " q Based on a structured process for collecting and distilling knowledge from a group of experts by means of a series of questionnaires interspersed with controlled opinion feedback q The key elements of the Delphi Method: ä Structuring of information flow ä Feedback to the participants ä Anonymity for the participants q The Delphi method has been widely used to generate forecasts in technology, education, and other fields

24. © 2003 AIR Worldwide Corporation CONFIDENTIAL Uses of AIR Terrorism Model Results q Manage terrorism exposure ä Understand exposure concentrations relative to potential terrorism targets ä Help price terrorism coverage down to location-specific levels ä Establish underwriting guidelines to offer profitable coverage while controlling risk q Determine effects of the Terrorism Risk Insurance Act of 2002 q Quantify capital and reinsurance needs q Provide basis for ISO loss costs

25. © 2003 AIR Worldwide Corporation CONFIDENTIAL Model Results Confirm What We Know q Major cities have been identified as favored targets, particularly for conventional weapons attacks ä National symbols of government and capitalism ä Vital economic centers and embassies ä Places of amusement ä Critical infrastructure ä Mass casualties objective q Major urban areas offer freedom of relatively unhindered operations ä Surveillance of targets, meetings, movement ä Public street access to exterior of many buildings q Higher loss per event due to urban density ä Vertical exposure versus horizontal footprint ä Landmarks surrounded by dense commercial property, not parking lots q Higher replacement cost per square foot

26. © 2003 AIR Worldwide Corporation CONFIDENTIAL Similar Experience With Other Perils q Earthquake premiums are predominantly a California burden ä California average annual loss is 72% of U.S. total ä Total U.S. average annual earthquake loss is much greater than U.S. terrorism property loss estimates q Hurricane loss cost relationships also show variations similar to terrorism ä Florida is approximately 50% of U.S. total ä Florida average annual hurricane loss estimates are greater than entire U.S. terrorism property loss estimates ä Florida statewide is more than 10 times higher than New York state ä Miami Beach is over 100 times higher than Washington, D.C. ä After Hurricane Andrew homeowner premiums in Florida increased substantially

27. © 2003 AIR Worldwide Corporation CONFIDENTIAL Use of AIR Models in ISO Advisory Loss Costs q Industry-wide analysis ä Commercial property ä AIR industry exposure database ä Average annual loss ä Separate building and contents results q Modeled certified acts q Gross industry loss was adjusted for other factors ä Contingent BI ä Other commercial lines ä Alternative markets ä Loss adjustment expenses ä Federal backstop

28. © 2003 AIR Worldwide Corporation CONFIDENTIAL Terrorism Risk Insurance Act of 2002 Issues q State approval processes for rates and forms q Non-certified events q Significant change each year -- sunset in 2006 q Combined commercial business lines q No “occurrence” concept - based on annual aggregate q Not a pool - each company is on its own q No coverage for reinsurer losses q Existing policy exclusions remain q Profile of potential loss characteristics q Pricing and the market to date
