1 Natural Perils Pricing When coming closer together means being further apart Tim Andrews & Stephen Lau Finity Personal Lines Pricing and Portfolio Management Seminar 30 April Finity Consulting Pty Limited

2 When coming closer together..means being further apart $50 or $3,000 2

3 Natural Peril Pricing Approaches Moving closer together

4 What insurers did 5-10 years ago Reinsured cat cost Retained cat cost Blend industry and insurer data. Limited variation by zone Attritional weather Analysed separately based on 3-5 years data 4

5 Common practice today Reinsured Cat Cost Retained Cat Cost Other weather Cat model results and other external data used to vary results by zone Maybe 5-10 years data Riverine Flood Bushfire Address level. Pool based on insurer data, industry data and other data 5

6 Role of catastrophe models in pricing Pros Alignment with reinsurance pricing Can fall out of reinsurance process Efficiency one model Provide risk relativities Cons Transparency Licensing issues Other sources of risk relativities that are easier to access Challenges at address level Non-modelled perils in particular problematic 6

7 An alternative approach Involves assessment of reinsured cost of each peril Net Cost of RI Gross Cyclone Gross Earthquake Gross Bushfire Gross Flood Gross Storm Separate consideration of the pool, and use of external data and heat maps to allocate by region 7

8 Two key analyses for each peril 1. The size of the pool You may decide the Australia wide hail cost is $300m pa Property factors 2. Variations by location, property type. Build model for Australian population to generate target pool Roof type relativities Hail risk heat map Tile 1.0 Metal 0.7 Sum Insured shape 8

9 Index (Latest year set at 100) Estimation of Pools An estimate based on as much data as you can find Insurer Data Weather Data 70% 60% 160 National Storm Score Index (8 Year Rolling Average) % % % % 40 10% 20 0% * Selected 0 Earthquake Cyclone Bushfire Storm External data such as FFDI 9

10 An alternative approach Component Hail, Windstorm, Flash flood (potentially separately) Riverine Flood Bushfire Earthquake Cyclone Total Gross Cost Indicative $1.2bn $0.4bn $0.2bn $0.4bn $0.4bn $2.6bn 10 Around 35% loss ratio

11 Some advantages with alternative approach Its simple Consistency about where cost is allocated Components can be linked to data regarding underlying peril Heat maps will then make sense Largest component, being storm, is more robust Use of longer time periods means less likely to underestimate or overestimate cost More visibility of net cost of reinsurance 11

20 Insurers are more aligned on flood...but rates are moving apart Flood premiums vary significantly between insurers Almost all insurers have modelled flood peril in their premium rates Price impact to customers is huge 20

21 Unsophisticated Insurer Rating for Perils $845 No address level rating for bushfire $845 No address level rating for storm $845 $845 $796 $796 $796 $796 $796 $796 $796 Suburb loading may reflect bushfire risk (and other perils) for the area However loading may vary significantly between neighbouring suburbs

22 A Typical Insurer Rating for Perils $1362 $1180 $1180 $1180 $1362 $1180 $1180 $1230 Address level rating for bushfire for addresses close to bush No address level rating for storm Otherwise most addresses have the same premium $ $1190 $1215

23 Sophisticated Insurer Rating for Perils $2250 Address level rating for bushfire $2030? Indication of address level rating for other perils $1920 $2050 $2252 $1950 $2018 $2035 $1730 $1908 $

24 Our Perils Rating Scorecard for Insurers Flood Bushfire Storm Cyclone % Insurers Rating for Peril 95% 70% 20% 80% Level of sophistication Sophisticated models but outputs vary significantly Mostly fairly basic modelling approach Unsophisticated Limited Address Rating Limited use of proximity to coast 24

25 Final Thoughts Enhancements to perils pricing have added price differences across insurers Be careful if you don t have peril models 25 Managing Customer Impact is Challenging
