Section 2Model Availability for Canadian Perils

What Questions Are Catastrophe ModelsDesigned to Answer? Where are future events likely to occur? How intense are they likely to be? For each potential event, what is the estimated range of damage andinsured loss?Catastrophe models are designed to estimate the probability of loss severity. Theyare not intended to forecast future events.GUY CARPENTER9

Current Canadian Licensed Modeling Capabilities– RMS- Earthquake- Fire-Following Earthquake- Severe Convective Storm (Tornado, Hail, Lightning and Straight-LineWinds)- Winterstorm (Freeze, Snow, Wind and Ice)- North Atlantic Hurricane (new to RMS v11.0)– EQECAT- Earthquake- Fire-Following Earthquake– AIR- Earthquake- Fire-Following Earthquake (not for automobiles)- Severe ThunderstormGUY CARPENTER12

Catastrophe Model Use in Canada by PerilEarthquake Available Models: RMS, AIR, EQECAT Usage:– RMS is widely used as compared to AIR / EQECAT inthe industry Latest Updates:– RMS: 2009- Western Canada PMLs increased about 30%- Clients generally bought more cat limit and there wereno capacity issues with the reinsurers– EQECAT: 2011– AIR: 2005GUY CARPENTER14

Catastrophe Model Use in Canada by PerilSevere Storm Available models: RMS and AIR Usage:– RMS is widely used as compared to AIR in the industry Latest Updates:– RMS updated their SCS model in 2008 (RiskLink v8.0)- Losses decreased approximately 30% pendinggeography and LOB– AIR's last Severe Storm model update was in 2005.GUY CARPENTER15

Catastrophe Model Use in Canada by PerilWinter Storm and Hurricane Available models: RMS Usage:– RMS only Latest Updates:– Winterstorm initial release in 2008– Hurricane initial release in 2011GUY CARPENTER16

Section 3Model Enhancements Expected in the Future

Upcoming Model Changes RMS– No Canadian model updates currently planned– Next Generation Platform scheduled for 2014– Respond to 2015 GSC update EQECAT– No Canadian model updates currently planned– RQE scheduled for late 2012– Research efforts underway on liquefaction, underwater landslide,tsunami, windstorm, hail, and flood AIR– Earthquake, Severe Storm, and Winter Storm likely in 2014– New Hurricane model likely in 2014GUY CARPENTER26

Section 4Managing Model Change and Uncertainty

Major Sources of Uncertainty Cat Models Data––––Address InformationMulti locationInsurance to value and other coverage issuesImperfect sight into risk characteristics HazardCourtesy of AIR Worldwide / EERI– Lack of history of large earthquakes limits our ability to simulate them- We rely on indirect sources of information, like GPS measurements orpaleo-seismology (e.g. historical liquefaction)– We know relatively little about seismicity potential in areas of low seismicity(like in Eastern Canada)– Even in areas of high seismicity like southwestern Canada, there is a limitedamount of data and there is room for the unexpected (Japan M9.0 in 2011,for example) Engineering– Limited claims data for catastrophic events– Lack of understanding of structural behavior under severe loadsGUY CARPENTER28

ConclusionGUY CARPENTER

ConclusionSome Basic Things to Remember Regarding Cat Risk Widespread and deep usage of models is relatively young Models are models: there are many uncertainties in them Data and scientific hypotheses all matter a lot Suitability analyses of models will be increasingly important Don’t assume a catastrophe model is useful – prove it useful yourself orrely on another to helpGUY CARPENTER3939
