HailAUS version 4.0

HailAUS is a stochastic hail loss estimation model for selected urban regions of eastern Australia. 

HailAUS is based on state of the art representation of the relevant climatological forcing, thorough parameterisation of the underlying impact processes and detailed portrayals of the spatial and temporal variability of the exposure and vulnerability patterns.  HailAUS 4.0 is a physical model, whose final product consists of loss files presented in a range of probabilistic formats.  It does not, for example, include financial routines for analysing policy and reinsurance structures.

HailAUS 4.0 is an enhanced and expanded version of earlier versions (v2.1 and v3.0) of the software.  HailAUS 4.0 analyses the following portfolio types:

• Residential property (household building and contents)
• Domestic motor vehicle
• Commercial property (building, contents and business interruption)
• Industrial property (building, contents and business interruption)

For the largest exposed urban regions in Australia:

• Extended Sydney (covering CRESTA Zones 40, 41, 42, 43 and 44)
• South East Queensland (covering CRESTA Zones 1 and 2)

Resulting insured losses are estimated:

• On a per storm (event) and annual aggregate basis
• By individual and aggregated CRESTA zones
• By individual and combined lines of business
• By individual and combined regions
• In Australian dollars and as percent of insured sum
• Including user specified deductibles

HailAUS results are presented as probabilistic loss distributions in graphical and tabular format.  Risk of loss is expressed as average recurrence interval (ARI) and annual probability of exceedance (AEP).  Loss summaries, sorted loss lists and chronological loss lists are created for each simulation.  To ensure statistical stability at the timescales of interest, losses are simulated over a 100,000 year period.

HailAUS 4.0 simulates losses using one of three input portfolio exposure options:

• In-built program data representing all risks in the region (household and motor only)
• Postcode level portfolio data (read from user-created text files)
• CRESTA zone level portfolio data (read from user-created text files)

Use of HailAUS 4.0 is based on a 3 year licence.  One licence covers multiple users of the software within a single company and e-mail and phone help is provided.  For further details contact Professor John McAneney or Roy Leigh on 61 2 9850 9683 or riskfrontiers@els.mq.edu.au
