AIR's 2004 U.S. Peril Model Updates Incorporate the Latest Scientific Advances

Boston, August 9, 2004 — AIR Worldwide Corporation (AIR) today announced the release of its 2004 U.S. hurricane, earthquake, severe thunderstorm and terrorism models. The updated models reflect the latest scientific and engineering research into these perils, as well as data on recent events, including last spring's record-breaking severe thunderstorm outbreak. Specific enhancements include a new approach to estimating the vulnerability of commercial structures to wind. AIR has also updated estimates of seismic hazard in the central United States based on the most recent report from the USGS and estimates of the frequency and severity of potential terrorist attacks. The 2004 updates also include, for users of AIR's CATRADER® software, a refined database of residential and commercial properties in the United States.

"The 2004 release represents the culmination of a significant research and development effort conducted over the course of the last year," said Dr. Jayanta Guin, AIR's vice president of research and modeling. "Our annual update process ensures that clients, who rely on the AIR models for critical underwriting, pricing and reinsurance decisions, have timely access to the latest research findings."

Key enhancements to AIR's models are as follows:

  • U.S. Hurricane Model — The 2004 hurricane model, which was recently recertified for use in ratemaking by the Florida Commission, features new component-based damage functions for commercial structures. The damage functions, which are used to generate loss estimates, now explicitly account for building height, a variety of building envelope characteristics, and repair costs, in addition to occupancy and construction type. The model also incorporates an updated historical storm set that includes all landfalling and bypassing hurricanes through 2002.
  •  
  • U.S. Earthquake Model — The 2004 earthquake model incorporates the findings of the USGS 2002 Open File Report on seismicity in the central and eastern U.S. In particular, estimates of the frequency and severity of potential large earthquakes in the seven-state New Madrid region and Charleston, South Carolina, have been updated in accordance with the latest recommendations of the USGS.
  •  
  • U.S. Severe Thunderstorm Model — The 2004 severe thunderstorm model includes an updated historical storm set to account for recent outbreaks, as well as updated tornado and straight-line wind event parameters based in part on AIR's recent post-disaster site surveys. AIR has also updated its hail damage functions for automobiles to account for the fact that hailstorms typically occur in the late afternoon, during peak commuting hours, when exposure is high.
  •  
  • U.S. Terrorism Model — The 2004 terrorism model incorporates the latest threat assessments from AIR's external team of terrorism and counterterrorism experts. The panel determined that there is an increased threat to softer, but still high-value targets, such as transportation facilities and prominent commercial buildings, and a lowered threat to well-protected sites, such as federal facilities and nuclear plants. AIR's comprehensive landmark database has also been updated, including newly identified "trophy" targets.

The 2004 release also includes a newly enhanced database of industrywide property values, which is incorporated into AIR's CATRADER software. The new procedure for estimating property values is based on highly detailed information, including construction and square-foot estimates for both residential and commercial properties. The data set draws information from AIR's new residential replacement valuation tool, ISO HomeValueTM, and ISO's extensive SPISM database of commercial properties.
