Guy Carpenter launches satellite-based catastrophe evaluation service

GC CAT-VIEWSM helps insurers assess losses from UK floods

Toronto, ON (Feb. 28, 2014) – Guy Carpenter & Company, LLC, the leading global risk and
reinsurance specialist and member of Marsh & McLennan Companies, has launched its new satellite-based catastrophe
evaluation service, GC CAT-VIEWSM, with the announcement that it has started using the service to provide clients
affected by the recent UK floods with initial insured loss estimates.

The new service, which is provided through an exclusive partnership with specialist geo-information
services provider Geospatial Insight Limited, analyzes Earth Observation (EO) Satellite and radar
imagery, plus footage from unmanned aerial vehicles (UAVs), the media and social media, as well
as ground-survey data, to produce initial loss estimates. Using GC CAT-VIEWSM, Guy Carpenter
has been able to analyze detailed imagery of the areas affected by the recent UK floods to map the
flood extent. By overlaying geocoded client risk location data, the team is helping insurers identify
which policies have been affected and providing associated potential loss estimates. The data will
in the future also be used to prioritize and deploy loss-adjusting capabilities.

Moving forward, Guy Carpenter will be able to use GC CAT-VIEWSM to conduct rapid loss
assessments for other major natural catastrophes. Initial loss estimates based on specific client
portfolios can be provided within days of the service being deployed for a particular event.

Commenting on the launch and the initial work carried out with insurers affected by the recent
floods, Nick Frankland, CEO of EMEA operations at Guy Carpenter, said: “We are delighted to be
able to deploy our new GC CAT-VIEWSM capabilities to assist our clients in quantifying the impact
of the worst flooding experienced in the UK since 2007.”

Vic Jenkins, from the newly created International Strategic Advisory team and Head of Analytics for
UK, MENA and South Africa at Guy Carpenter, added: “Previously, establishing a reliable flood
extent would have taken a considerable amount of time and required significant expense to compile
and verify the necessary data. Using the latest imaging and analysis technology, we can respond
quickly to a catastrophe event, providing our clients with robust information to help them plan and
respond in a matter of a few days following the deployment of GC CAT-VIEWSM.”
