Sompo International is a leading global provider of property and casualty insurance and reinsurance

Sompo International have operating subsidiaries servicing clients worldwide through platforms in the US, the London Market, Bermuda and Lloyd’s. They required detailed flood hazard information in order to support risk selection and portfolio management decisions for their international property, marine and energy portfolios.

As part of this they wanted to know how they could:


Identify those risks that are exposed to flood hazard and those risks that are not?


Measure and manage aggregations of flood risk in a robust manner across all lines of business?


Achieve this in the most efficient way possible?

Our Solution Fathom-Global provided detailed, global hazard information for both fluvial and pluvial flood risk for a range of return periods.

The completeness and resolution of this information allowed Sompo International to deploy it in their underwriting workflow in a consistent fashion for all types of risk and across all locations.

Fathom-Global’s flood aggregation zones also allowed them to monitor accumulations and assess the impact of underwriting decisions on the global portfolio.

The Results Flood risk is now a peril analysed by Sompo International using detailed and credible risk intelligence.

This has the potential to improve both underwriting and portfolio management decisions and provides greater certainty in the quantification of a critical catastrophe risk.
