Casualty Treaty

Advent offers a wide range of Casualty and Specialty reinsurance coverages across manifold classes, territories and client groups. We have the ability to quote and lead programmes which allows our brokers to access innovative solutions, superior service and stable capacity through one single team that concentrates on long-term, relationship driven business. We focus on providing solutions for our clients’ needs and have a pro-active approach to facilitating the most bespoke, creative and achievable results in our chosen fields.

We have a maximum programme line size of US$7,500,000 and our three main segments are as follows :

Casualty Treaty

We provide mainly excess of loss coverage for a broad portfolio of classes that fall under this category. The USA is by far the largest domicile component but we also entertain an International element which includes territories as far and wide as Canada, Japan and Australia.

We prefer to partner with small to medium-sized reinsureds and can offer protection for mono-line, mono-state reinsureds to multi-line, super-regional customers.

Our specialist and niche focus allows us to engage with aligned entities to work towards specific resolutions for their concerns.

We will consider all classes and products on case by case fundamentals and individual merit with our main coverages sold through an excess of loss product for the following on both a risk exposed and cat/clash basis.

We are also able to consider multi-line coverages i.e. Property and Casualty combined programmes.

London Market Casualty

We offer excess of loss protection for either Lloyd’s syndicates or London Market entities that generally write an underlying Direct and Fac portfolio whether a bouquet of International and/or US classes or an individual class/niche. We are also able to provide cover for Treaty underwriters i.e. retro coverage but this will be almost exclusively through Cat/Clash protections.


We offer excess of loss protection for US, International and London Market entities writing Direct and Fac General PA portfolios. We are also able to provide retro coverage to clients but this will usually be on a Cat basis. The PA/Specialty account will contemplate classes such as Kidnap & Ransom, Piracy, Contingency, Travel, Common Carrier, Sports and War/Terrorism/Political Risk or any combination thereof that are justifiably considered short tail.

We also have a limited aggregate of NBCR capacity available for the above classes.
