As part of an insurance industry project Global Exposure, Accumulation and Clash (GEAC), the Cambridge Centre for Risk Studies, in collaboration with Risk Management Solutions and Praedicat, is pleased to host a workshop on scenario development and usage. This workshop will focus on methodologies for developing and applying scenarios for insurance classes beyond property catastrophe lines, and particularly for scenarios that address clash. A number of multiline clash scenarios will be developed as part of the GEAC initiative. This will be made available through the RMS(one) Exposure Manager platform, as well as empowering participants to develop their own scenarios. 

The workshop brings together stakeholders from across the insurance and reinsurance industry to advance best practices in the development and application of scenarios in insurance decision-making. The workshop is for companies that develop their own multiline clash scenarios, that apply scenarios produced by others, or who report mandated scenario losses to regulators or rating agencies. 

The workshop will be followed by drinks and a private dinner at Corpus Christi College, University of Cambridge.

Please note this is an invite-only event.
