4 What Is Predictive Modeling Predictive modeling uses historic data to identify patterns that can be used to predict future behavior. At individual risk level And also aggregated to class or portfolio level These predictions are then used to inform business decisions. Insurance predictive modeling takes many forms. Costs Conversion/renewal behavior Operations Wider customer behavior 4

5 The Problem With Prediction It is exceedingly difficult to make predictions, especially about the future. (Niels Bohr, Nobel laureate in physics) It is often said there are two types of forecasts... lucky or wrong. (Institute of Operations Management ) I think there is a world market for maybe five computers. (Thomas Watson, Chairman of IBM, 1943) 640K ought to be enough for anybody. (Bill Gates in 1981 maybe) 5

7 But In 1999, Billy Beane (manager of the Oakland Athletics) found a novel use of predictive modeling. Using predictive analytics, Beane was able to identify and hire players undervalued by the market. A year later, the A s ranked 2 nd. Implication You only need to be more accurate than before. Predictive models can aid the human expert BUT need the expert to define the framework. 7

9 Predictive Modeling Use Has Increased for Nearly Every Line of Business; Standard Commercial Carriers Have Aggressive Plans, but a Gap Will Continue in Specialty Lines Does your company group currently use, or plan to use, predictive modeling in underwriting/risk selection and/or rating/pricing for the following lines of business? (Q.2) Personal automobile Homeowners Workers compensation General liability/cmp/bop Commercial property/cmp/bop Commercial automobile Specialty lines 2013 (n = 40) 2012 (n = 45) 2013 (n = 37) 2012 (n = 41) 2013 (n = 34) 2012 (n = 27) 2013 (n = 45) 2012 (n = 33) 2013 (n = 47) 2012 (n = 34) 2013 (n = 42) 2012 (n = 33) 2013 (n = 31) 2012 (n = 14) 26% 32% 30% 28% 24% 13% 30% 80% 75% 62% 58% 47% 38% 33% 40% 15% 5% 19% 6% 33% 5% 33% 9% 41% 12% 41% 21% 45% 22% 34% 53% 15% 38% 32% 60% 12% 43% 33% 45% 22% 42% 48% Currently use Plan to use Do not use and no plans to use Personal lines Standard commercial lines Specialty commercial lines Source: Towers Watson s 2013 Predictive Modeling Survey Base: U.S. respondents giving a valid answer (percentages exclude Do not write this line of business ). 9

13 Risk Selection A variety of considerations come into play when making a risk selection decision: Underwriting appetite and goals Underwriting guidelines Policy terms and conditions Expected cost of the risk Expected profitability of the risk Confidence around that profitability estimate The longer-term profit potential of the whole account (i.e., customer lifetime value) This presentation will address how analytics support these aspects. 13

14 Expected Cost of the Risk Risk models predict the individual risk s expected loss cost. Separately by claim type (e.g., property vs. liability) Typically model frequency and severity (and combine to loss cost); may also include a large loss propensity model Predictors in the model can include existing rating variables as well as new underwriting information (internal or external data) These models have been used in P&C insurance for over a decade. Started in personal lines (homogeneous risks, large volumes of clean data) Expanded to commercial and specialty lines Many companies are on third or fourth generation efforts 14

16 Need a Variety of Techniques to Solve Many Types of Business Problems We leverage a broad array of techniques. Examples include: Decision trees Systematic approach to slicing data Factor selection tool Spatial Analysis Define territories based on experience rather than geopolitical boundaries Define class codes using own experience These methods must be employed carefully to improve performance without losing the transparency of the model

17 Selecting Risks Based on Cost Cost is one indicator of good vs. bad risk. High cost risks can be good risks, however, assuming the right premium charged, coverage conditions applied, etc. A better metric for risk selection is expected loss ratio. 17

18 Underwriting Profit Scoring Models By incorporating premium into risk models, they can be easily translated into underwriting profit scoring models that rank risks according to profitability underlying current rates.

25 Considering Both Expected Loss Ratio and Associated Variability Can Improve Underwriting Process Flow Companies can establish underwriting processes in consideration of both the underwriting profit score and the degree of confidence in the score calculated for a particular risk. This allows underwriters to focus on those risks that need it most. Variability High Low Underwriting (drill down to increase confidence) (A3) Automated Underwriting (A1) Underwriting (apply loss prevention or other UW support) (A4) Automated Underwriting w/ Price Check (A2) Low High Expected Loss Ratio 25

26 Underwriting Process Flow In a recent investor day presentation, Travelers showed that between 2006 to 2013, the number of submissions for its Select Express product that were straight-through processed increased from 17% to 80%. 26

27 Selecting Risks Based on Expected Profitability Selecting risks based on expected loss ratio will result in a portfolio of risks that are immediately profitable. What about risks that may become profitable in the future? Longer-term profitability is measured as the net present value of the cash flows attributed to the relationship with a customer. This requires estimation of: A profit metric (revenue minus costs) How the risk will change over time (both customer-initiated changes and companyinitiated changes) Likelihood of persisting Likelihood of cross-selling and up-selling A discount rate Referral Cross-sell Up-sell Up-sell Referral Current Product 27

36 Customer Lifetime Value (CLV) CLV is the cash flows attributed to the relationship with a customer. Whole of the Wallet Lifetime Value Expected Cross Sales Lifetime Value Acquisition Value Profit Potential Profit Time Future Lifetime Value Value at Risk 36

37 Calculating CLV: Simple Example Annual premium: $1,000 (constant over time) Profit: 10% accounted for at the end of the policy and fixed over the life of the customer Retention: 90% with no mid-year termination Acquisition cost: $400 Discounting rate: 15% CLV = 100/ * (0.9) / * (0.9) 2 /

40 Leveraging Analytics for Distribution Management These metrics (or combinations) can be very useful in informing the distribution channel and influencing its performance. Expected cost Expected loss ratio Expected demand Customer lifetime value The following is a case study demonstrating this. Up-sell 40

61 Integrating Demand in Pricing Decisions Elasticity Analysis: If we can understand both expected cost and the customer s sensitivity to price offers, we can develop an optimal strategy that achieves the company s objectives in terms of profitability, volume and other enterprise goals. Market Competition Current Portfolio Needed Price Change Future Portfolio Future Portfolio 61

62 Implementing Price Decreases Example 1 Account A Account B Actuarial Cost Model Indication -15% change -15% change Elasticity High Low CRM Strategy Price-based Service-based Near-Term Pricing Action Change rate -15% Change rate -5% Results Attract/retain more business Maintain strong profit margin 62

63 Implementing Price Increases Example 2 Account C Account D Actuarial Cost Model Indication +15% change +15% change Elasticity High Low CRM Strategy Price-based Service-based Near-Term Pricing Action Change rate +5% Change rate +15% Results Attract/retain more business Rapidly restore profitability 63

64 Selecting Optimal Prices In regulated lines that require a filed rate to be charged (e.g., private passenger auto) the filed rate is often selected as a cost-based price with prudent deviations for: Business objectives: competitive position, profit and volume goals, tolerance for dislocation Constraints (regulatory, operational) Deviations can be determined based on: What if scenario testing Optimization algorithms This concept of using analytics to select prices that better achieve goals is completely relevant to commercial lines as well ( more on that later). 64

65 Quantitative Competitive Analysis Can Advise Where Price Changes Can Improve Competitive Position 65

66 Selecting Optimal Prices Many other key performance indicators (KPIs) can be measured in order to make sound pricing decisions. Profit $ or % Volume (premium volume, policies in force, retention rate, conversion rate) Subsidy Dislocation Competitive position This requires data integration in a price assessment environment A customer dataset (e.g., in-force policies) Current premiums Competitor premiums Risk models Demand models Expense assumptions The following case study considers what if scenario tests of changing a filed rate order calculation. 66

70 Price Optimization Modern analytical approaches (e.g., price optimization) use mathematical algorithms to systematically integrate risk and policyholder behavior in selecting a price for the individual risk. This removes judgmental bias from the selection process. 70

71 Customer Knowledge Is Used to Simulate a (Constrained) Search Space of Potential Price Changes A search space for one policy constrained by allowable rate change S1 S2 S3 S4 Expected profit Different business objectives have different optimal prices Retention rate Profit per policy S1 Maximize volume S2 Current rates S3 Cost-based rates S4 Maximize profit Price Premium for policy in question 71

74 A Wide Array of Constraints Are Introduced Into the Optimization Algorithm, Reflecting Internal and External Considerations Policy-level constraints (e.g., an allowable range of premium changes) Portfolio level constraints Dislocation Profitability Competitiveness Universal constraints The result of the optimization is expressed as a rate order calculation. The rate should not be inadequate, excessive or unfairly discriminatory. 74

75 Optimization Can Be Expanded to Consider Profit, Volume and Other Metrics (e.g., Customer Lifetime Value, Account Profit) 75

76 Uses of Price Optimization Price optimization is gaining speed in personal lines with demonstrated improvement in profit and/or volume. In unregulated commercial lines, producing a suggested retail price (via price optimization) can be used for: Risk selection Informing agent/underwriter judgment Guiding final price decisions 76

77 Summary Insurance companies are competing on data and analytics. Arming the underwriter and distribution channel with more insights leads to better decisions. Analytics can help estimate loss costs, profitability, customer behavior and customer lifetime value. Integrating these analyses can support underwriters with: Risk selection and underwriting process flow Distribution management Guiding price selections 77
