Aggregation Modelling


The Aggregation Modelling team is responsible for the monitoring, modelling and reporting of exposures for all underwriting divisions.

Providing information from several risk tolerance metrics helps to minimise risk and maximise knowledge of the syndicate’s exposure to both natural and man-made catastrophe events.

Through integrated underwriting, aggregation and catastrophe modelling systems, Ark is able to proactively manage portfolios and conduct risk assessment scenarios in order to gain a more comprehensive understanding of a risk before it is written.
