Building for Resilience: How to Avoid a Catastrophe Model Failure

Posted at 1:00 AM ET

Here we bring together our recent multi-part series on model resilience by Guy Carpenter’s Global Chief Catastrophe Modeler, Imelda Powers.

Since commercial catastrophe (CAT) models were first introduced in the 1980s, they have evolved as new scientific discoveries and claims insights emerged. Despite the sophisticated nature of each new generation of CAT models, occasionally a model misses a significant loss driver for a particular peril. This occurs when a previously hidden attribute reveals itself through unprecedented intensity. Lessons from such surprises stimulate model improvements as our understanding of the physics of the peril and its damage potential, increase. Through this process, models mature over time.

Valuation Assumptions

There is no database of agreed property, contents or business interruption valuations among vendors or insurers.  Any user’s particular valuation may come from databases of property prices, or rebuild values from claims adjusters and building surveyors. If the model’s assumed valuations are under- or over-estimated, then the damage function may over- or under-compensate in order to balance to historical industry event losses during the model-building process. Consequently, it is important that the user adjust the damage module to reconcile these differences.

If resources permit, an insurer may carry out additional, micro level model suitability analyses - including a review of model hazards and vulnerabilities using the latest scientific literature and engineering studies. Guy Carpenter’s Model Suitability Analysis (MSA)® framework is designed to guide users through such an analysis.

Model Suitability Analysis

There is a repertoire of tests, at both the macro and micro levels, to evaluate the merits of a CAT model.  Regardless of resources, insurers should analyze how each test’s result informs their view of risk. Here we review the macro level.

  • Data integrity and availability as critical as data confidentiality
  • Limited ability to quantify dependency a major cyber inhibitor
  • Challenge to build clearly differentiated cyber portfolio

Diversification is essential for evolving the cyber insurance market, yet expanding the cyber remit beyond data confidentiality and further into areas such as operational technology risk, data availability and integrity demands a common cyber risk currency, according to Morley Speed, Managing Director, and Carolyn Morley, Chairman, Global Casualty, Guy Carpenter.
