Pricing a New Product
Many different ways to price a new product High Level Overview:
New Variables- Determine factors (multivariate analysis)- Determine base rates- Consideration of competition, disruption in marketplace, regulatory
New Underwriting Guidelines- Determine impacts of changes in mix
Will product be New Business Only or Conversion?- Conversion – determine disruption on current book
Calculate / Approximate the adequacy of filed rates Compare to current book of business
Determine Expected Loss Ratio as starting point
New Product Rolls Out – Now What?
Business team needs metrics to determine how product is doing Adequacy of pricing Reserving ultimates for financial reporting Planning / Forecasting
- Expected experience in future years
New Product Rolls Out – Now What?
Use Expected Loss Ratio from pricing analysis as initial “best guess” As losses begin to be reported, watch out for:
Distortions in Loss Development- Average Accident Date is not at midpoint of time period- Distorts in times of extreme growth or decline
“Large” Losses Seasonality Comparisons to current book of business Changes in Mix
- State distribution- Type of insured

“Large” Losses
How do you provide suitable results to business team without threat of overreaction?
Impact of Large Losses Large is typically considered $100K or even more Normally don’t expect large losses to impact short tailed lines
(Comprehensive, Collision, Property Damage) Early in rollout, calculate the Loss Ratio impact of $25,000 loss (average
cost of totaled car)- Provide to business team to give sense of materiality

Seasonality
Significant impact on loss ratio experience Weather Travel
Geographical differences abound Impact of catastrophes on comprehensive coverage First year and beyond – uneven weight of premium by state can cause
distortions in the loss ratios When comparing Actual Loss Ratios to Expected Loss ratios
Adjust ELR’s for seasonality Normalize actual loss ratios

Book of Business
Additional analysis on where loss ratio is expected to go in future years As book of business ages, we expect loss ratios to improve Assumptions:
New Business Penalty / Renewal impacts on Loss Ratio Growth in New Business Retention Filed Rate Changes
Other Considerations
Separately analyze Catastrophe claims Excess / Large Losses
Analysis completed both with LDF method and Bornhuetter-Ferguson method to reduce volatility
Incorporation into Planning
Projections of future new business growth Projections of future retention / renewal
Incorporate into loss ratios, making additional adjustments for Seasonality Expected Excess Losses Expected Catastrophe Losses Additional mix shifts Anticipated rate / factor adjustments
Advantages of Monthly Methodology
Responsive – allows business team to analyze data and make decisions quickly Monthly loss development limits distortion due to growth Monthly loss development allows drill down Comparison to existing products allows recognition of environmental factors
Disadvantages of Monthly Methodology
Responsive – loss ratios can bounce around from month to month Responsive – susceptible to distortion by large losses Credibility – takes several months to have enough data to analyze Monthly loss development still may have some distortion due to growth Potential differences in loss development between products Potential impact of mix changes in book of business
Other Applications
Applies to more than just New Product rollout New Distribution Channel New States Accelerated Growth
