The Catastrophe Risk Management department consists of three closely coordinated units, which primarily deal with (a) property exposures and natural perils, (b) technical and scientific catastrophe risk modeling issues, and (c) non-natural perils and casualty lines of business.

The property-natural perils unit is responsible for modeling property exposures to natural perils and monitoring property accumulations with respect to natural catastrophes. The scientific catastrophe modeling unit evaluates the commercially available natural catastrophe risk models, and provides technical expertise on underwriting and accumulation issues, as needed. The non-natural perils and casualty unit, added in the wake of September 11, 2001, identifies, measures and monitors the Company's exposures to potential catastrophes across all lines of business, including possible clashes between different lines.

The staff of the Catastrophe Risk Management department can help you to:

• Understand the scientific basis of catastrophe risk modeling and identify the natural perils that your portfolio is exposed to
• Perform post-event analysis and ascertain the lessons learned from an underwriting perspective
• Evaluate your catastrophe loss potential and restructure your portfolio and reinsurance coverage
• Identify catastrophe clash potentials among different lines of business
