Aspen Re Goes Live with RMS Solution for Exposure Management

HAMILTON, Bermuda, August 14, 2007 — Aspen Insurance Holdings Limited (NYSE:AHL) (‘Aspen’) announces its launch of a custom-developed risk management platform to identify the concentration of exposures across its reinsurance and insurance portfolios.

‘RiskClash’ is a bespoke solution developed specifically for Aspen by Risk Management Solutions (RMS), the world's largest provider of products and services for the quantification and management of catastrophe risks. Whilst previous risk modelling tools employed by Aspen’s catastrophe risk management team were able to aggregate risk according to postal or zip codes, RiskClash is the first system designed to model single site risk accumulation across combined insurance and reinsurance lines down to a city block, subject to data being available. The core advantage of the RiskClash system is its ability to determine Aspen’s aggregated exposure across its entire risk portfolio and identify post loss potential exposure in key geographical locations to a high level of accuracy.

In addition, the system will allow Aspen to run “what if” scenarios using any country and peril, enabling them to gain a more comprehensive understanding of a risk before it is underwritten.

Oliver Peterken, Chief Risk Officer at Aspen, commented: “The fundamental reason behind the development of RiskClash is our continuing desire to minimise risk and maximise knowledge of our exposure. This is a significant step for both Aspen and the market. The new system provides numerous benefits to our risk management, but most importantly it means we can provide a higher quality of underwriting.”

Jason Futers, Vice President of the RMS London market practice, said: “Robust enterprise risk management is becoming an increasingly important source of competitive advantage, as rating agencies and regulators pay ever closer attention to how insurers and reinsurers manage their portfolios. Developing RiskClash is the natural progression of Aspen’s relationship with RMS. It allows Aspen to drill down to a far more detailed level of risk, giving them greater control over their total risk exposure and even more confidence in how they underwrite business.”
