We write casualty treaty reinsurance for clients around the world, from Europe to emerging markets, on a proportional and non-proportional basis.

We offer cover for a broad range of products including public and products liability, professional lines, motor, workers’ compensation/employers’ liability and personal accident.

Our focus is on building strong partnerships that bring lasting benefits to our clients.


Debbie McLachlan

Product Group Leader, International Casualty Treaty

Before joining Convex, I’d built up 25 years of reinsurance underwriting experience in various parts of the world, including continental Europe, Asia Pacific and Latin America.

Like my colleagues across the business, I’m excited by the opportunity to help build an insurance company from the very beginning and to partner both with clients we have worked with for years as well as new companies.

“Our aim is to build long-term partnerships with core clients across all our portfolios. We value an open dialogue on the exposures facing our industry today and look to collaborate with our partners with a view to providing risk-transfer solutions to address these”
