Atrium has written Casualty Reinsurance in excess of 25 years and is a recognised lead and quoting market here in London.

Andrew Winyard, Head of Casualty Reinsurance, joined the Atrium underwriting team in 1986.  Andrew travels extensively in North America to meet both clients / brokers and attends a number of the industry conferences, being involved in a presentation capacity at some.

The portfolio is focused towards small to medium sized North American reinsureds, where we believe the desire to develop long-term relationships is mutual. A number of the syndicate’s clients have worked with Atrium in excess of 20 years. We look to work constructively with our clients and brokers, to structure programmes and coverage in line with their requirements and to be able to provide meaningful capacity.

We make our underwriting decisions at the box and are therefore able to offer excellent turnaround times and availability to the broker market. Atrium’s view is that the underwriting team’s own experience and judgement will remain core to our risk selection process, this is backed up with strong box-based actuarial analysis and internal models.
