Ascot Underwriting Ltd Selects AIR's Risk Modeling Software to Help Manage Its Global Catastrophe Risk

Relationship Highlights AIR's Expanding Involvement with Major Players in the Lloyd's Market

BOSTON, October 20, 2004 — Ascot Underwriting Ltd (Ascot), a managing agent at Lloyd's of London, has selected AIR Worldwide to provide risk modeling software to manage its catastrophe risk. Ascot has licensed AIR's CATRADER® and CLASIC/2TM software applications and will use AIR's modeling technology to manage its catastrophe risk globally.

"AIR provides detailed, scientifically advanced and easy-to-use catastrophe modeling applications that will aid us in our underwriting and accumulation control and will allow multiple permutations of portfolio review," said Ascot Risk Manager Robert Dimsey. "We took this strategic decision to implement AIR's modeling technology across our full range of business to enhance our direct, facultative and catastrophe treaty underwriting worldwide."

CLASIC/2 allows insurers to estimate catastrophe loss potential at any level of detail down to an exact street address. It accounts for construction and occupancy type, building age and height, and more than 30 risk-specific structural details. CLASIC/2 incorporates an NWP-based extratropical cyclone model for Europe. With this capability, insurers can model European windstorm losses at the individual risk and policy level utilizing risk modeling techniques based on the actual physics of the atmosphere.

Ascot will also be using CATRADER, AIR's industry-standard treaty reinsurance application. CATRADER includes a unique U.S. property value exposure database that draws on information from AIR's new residential replacement valuation tool, ISO HomeValueTM, and ISO's extensive SPISM database of commercial properties.

"Over the past year, we have extended the scope of CLASIC/2, our detailed modeling system, to include Europe and made it easier for cedants and reinsurers to exchange detailed exposure data," said Neil Wiseman, managing director of AIR Ltd. in London. "Our relationship with Ascot represents AIR's expanding involvement with many key syndicates in the Lloyd's market, and we're very excited at the prospect of working with the highly professional team of underwriters and analysts at Ascot."
