Guy Carpenter Develops Industry�s First Frequency and Severity Model for Analyzing U.S. Publicly Traded Directors & Officers Liability Risks

Designed to help underwriters determine loss potential of their D&O portfolios

NEW YORK, February 11, 2004 In response to insurance companies� need for more effective tools to manage their Directors & Officers Liability Insurance (D&O) portfolios for U.S. publicly traded companies, Guy Carpenter & Company, Inc. announced today the launch of the industry�s first model for analyzing and forecasting the frequency and severity of securities class action suits, which account for the majority of D&O insurers� loss activity. The new LEAD™ model (Loss & Exposure Analysis for D&O), developed in conjunction with Marsh & McLennan Companies subsidiary NERA Economic Consulting, is available for the exclusive use of Guy Carpenter clients and uses policy-level data to help insurers determine the loss potential of individual D&O policies as well as portfolios.

�Taking into account the historical difficulties in modeling this line of business, the LEAD™ model represents a significant step forward in analyzing D&O risks,� said Chip LaLone, Principal and head of Guy Carpenter�s worldwide D&O practice. �When used in concert with Guy Carpenter�s MetaRisk® model, our clients can better assess the reinsurance options available to them, calculating the tradeoffs between various strategies.� The MetaRisk® model is a proprietary dynamic financial analysis platform, used by Guy Carpenter clients to facilitate their reinsurance decision-making process.

The LEAD™ model brings together a wide range of publicly available data, including stock issuer characteristics, stock trading information, financial statement metrics and stock ownership breakdown, to calculate the likelihood that a portfolio company will face a future securities class action suit, as well as estimate the severity of the class action. D&O insurers will be able to use the LEAD™ model as a risk selection/avoidance tool to help analyze and manage shifts in frequency and severity within their portfolios, evaluate risk/reward of different attachment points, and supplement existing D&O reserving methods.

�The LEAD™ model was engineered through a collaborative effort between Guy Carpenter and NERA that spanned the past 12 months, leveraging our combined in-depth understanding of the D&O market,� said Dr. David Tabak, Vice President at NERA. �The result is a highly sophisticated model based on NERA’s proprietary database of securities class actions that can be used to analyze the D&O portfolios of Guy Carpenter�s clients in a uniform way, despite the fact that each is underwritten differently.�
