Technical and industry working groups

Teams in Reinsurance and Catastrophe adopted to deliver a defined piece of work, each with a workplan, a supervisor and a clear end. A working group has no public authority beyond its workplan.

01In brief

The short answer.

A working group of Reinsurance and Catastrophe is a team adopted to deliver one defined piece of work in the insurance and catastrophe field, with terms of reference, a workplan, a supervisor and an end date. Candidate subjects come from the platform's topics, such as aggregate accumulation. A working group holds no authority beyond its workplan, and its outputs are reviewed before publication.

From enquiry to contribution.

Canvas · from enquiry to contributionDesign, not a record
Technical and industry working groups: a working group from charter to sunsetA charter sets the question and the code of conduct; members join with declared interests; a workplan produces deliverables that are reviewed and credited; the group reports and sunsets or renews. Design of the process, not a record of a run.

03Geography

People and exposure in the Gulf of Mexico coast.

For technical and industry working groups, in GRA's spatial-finance reading, the map opens on population density and night lights with night lights tonight from NASA GIBS, framed on the Gulf of Mexico coast; every other NASA layer, live feed and forecast waits in the layer list.

The interactive map needs JavaScript; the layer list and sources are below.

04How it works

Working groups in Reinsurance and Catastrophe.

  • Each entry shows its scope, host or owner, and terms.
  • Participation follows published rules, applied equally.
  • Taking part gives no authority or influence over findings.
05Proposed deliverables

What a Reinsurance and Catastrophe working group would produce.

  • A cat model validation checklist, built from public sources and reviewed before release on Reinsurance and Catastrophe.
  • A glossary of trigger types, built from public sources and reviewed before release on Reinsurance and Catastrophe.

A Reinsurance and Catastrophe working group would have a workplan, a supervisor and an end date, and would draw on open-model work, post-event loss analysis and review.
