RMS Releases Advanced Daily Simulation Model for the Weather Derivatives Market

Newark, Calif. - November 5, 2001 - Risk Management Solutions (RMS), the world's leading provider of products and services for the management of natural hazard risks, today released an advanced daily temperature simulation model that provides weather traders, risk managers, and corporate end-users with a sophisticated new capability for valuing weather derivatives. This new capability is available to RMS clients in Climetrix® version 3.0, the latest release of the company's weather derivatives trading and risk management system.

The new daily model offers an alternative to the index modeling capabilities also available within the Climetrix system. While index models rely on an aggregate-level analysis of historical index values, the new RMS daily simulation model analyzes weather risk by simulating the day-by-day progression of temperatures over thousands of years of simulated weather. The model uses extensive records of historical daily temperature data for individual weather stations as the baseline for this analysis.

Bob Henderson, head of research at Element Re Capital Products, commented, "We believe that daily modeling capabilities provide important insights into weather risk beyond what is possible with the index models that have traditionally been used in the market. As daily models evolve over time, we expect many market participants to move towards using such models as the primary basis for both trading and portfolio risk management."

By simulating a time series of temperature data, the new daily model provides superior information for valuing certain types of weather contracts that are difficult to analyze accurately with an index model. These include contracts based on shorts periods of time such as one week, or those based on event indexes that measure the number of times a specific temperature threshold is reached. The daily model also provides an alternative perspective for the analysis of contracts based on standard degree day or average temperature indexes.

"Developing a robust daily model is a very challenging undertaking due to the numerous complexities of temperature behavior, such as seasonal patterns in daily temperature variability and correlations in day-to-day temperature values," noted Dr. Anders Brix, senior modeler at RMS. "Our new model addresses these and other complexities and is the result of an intensive R&D effort over the past year."

RMS will be hosting seminars in Houston, New York, and Frankfurt on November 8, 9, and 13 to introduce the new daily model. The Frankfurt presentation will take place immediately prior to the Weather Risk Management Association's annual European meeting. For more information, contact RMS at climetrix@rms.com.

Climetrix is an Internet-based application that provides integrated access to all of the data, advanced pricing tools, and portfolio management capabilities necessary for successful participation in the weather market. The application can be accessed at www.climetrix.com. Since the initial release of Climetrix in July 2000, more than 70% of active weather market participants have licensed the system or the underlying weather data.
