With experienced specialist underwriters and an embedded modelling capability, we provide superior service to our clients and brokers on both standard and complex risks.

Our Product

The Property Treaty account is focused on Catastrophe excess of loss and Risk excess of loss where significant capacity can be offered in lead or follow positions. Smaller additional segments of the account include Agriculture, Terrorism and Property pro rata. The underwriting team is divided into North America and International.

On the North American side, the Catastrophe portfolio comprises nationwide and regional carriers. The Risk excess portfolio is made up of Primary and E&S carriers on a regional, nationwide and worldwide basis.

Internationally, the portfolio has global scope but the main territories are Europe, Japan and Australia where business is predominantly written on a Catastrophe excess of loss basis. Underwriters utilise Brit’s representative office in Japan to assist in the writing and servicing of Japanese clients.

In our Bermuda office, we will be underwriting US property catastrophe reinsurance, retrocession and industry loss warranties. We aim to provide tailored property catastrophe solutions for our clients, both bespoke and on a subscription basis
