Claims Predictive Model Design Predictive modeling is the application of data mining and statistical techniques to effectively predict and segment claim outcomes by level of exposure, by transforming internal and external claim characteristics into model outputs to enable business actions that drive results. Model Inputs Several hundred internal and external characteristics are tested to identify the 50-100 with greatest predictive power Claim Segmentation Curve Data Mining & Statistical techniques Sample Model Equation w 1 (Claimant Age) + w 2 (Dist_H_W) +w 3 (Emerg_ Rm) + w 4 (Job Function) + w 5 (CoMorbidity) + w 6 (Report_lag) +. Outcomes Model Outputs John Smith 1 Circle Ave. Anytown, NY 92 Reason Messages: Multiple co-morbidities Claim history Emergency Room Distance from work -5- Low Claim Complexity High

Loss Segmentation Typically, 20% of claims represent 70-80% of loss costs Quickly and prospectively identifying claim exposure can enable proactive management strategies that can help drive better business results. 100% 20% 75% Claim Assignment Fraud Detection 50% 80% Claim Escalation 80% Competitive Advantage Reduced Loss Costs Medical Management 25% Business Metrics Claim Escalation 0% Claim Counts 20% Loss Costs -7-

Data is the Key By combining internal data with public external data, enhanced segmentation can be achieved. Claim Data Claimant Data Type of injury Injury timing Report lag Insured Data Tenure Type of work and job level Marital status Billing Policy and coverage Data Experience data Policy Data Synthetic Data Possible data sources Medical Data Performance metrics Number of employees Vendors/contractors usage Location specifics Complaints External Data Census /demographic Household Insured financial strength Industry loss data Legal environment -8- Treatment patterns Prior claim experience Pre-existing conditions Prescription usage

Providing Insights Beyond Injury Group Injury Group segmentation* provides further insight than traditional methods enabling segmentation of claims within like injuries and allowing other severity characteristics to come through. $160,000 $140,000 $120,000 $100,000 $80,000 $60,000 $40,000 Ave Severity: Sprain Strain Shoulder Ave Severity: Sprain Strain Neck & Back Ave Severity Contusion Excl Back & Shoulder $20,000 $0 1-10 91-100 Contusion Excluding Back & Shoulder Sprain Strain Shoulder Other * Patent Pending -9- Sprain Strain Neck & Back

Capturing the Dynamic Nature of Claims Advanced claims models recognize the dynamic nature of claims and provides through-time updated scores driven by new information (e.g., medical bills, pharmacy data). Aggregate Number of Office Visits Relative Projected Loss Cost 100% 80% 60% 40% 20% 0% -20% -40% -60% 0 1 2 3 4 5 6-10 11-20 21-30 31-60 Over 60 Month 3 Month 6 Month 12 Not all data is available at each stage in the claim lifecycle Characteristics change through time Expectations around certain variables can vary across time and injury types. Advanced modeling capabilities are required to address complexity arising from time-dependent predictive information. -10-

Enhanced Segmentation can be Achieved through Predictive Modeling Claims predictive models have the ability to consistently differentiate high cost claims from low cost claims from first report and through the life of the claim. 150% 100% 50% 0% At first notice claims scoring above 90 were over 3 times as costly as those scoring below 10 With 1 month that segmentation was enhanced to over 10 times -50% -100% Best 10% Worst 10% FNOL Mth 1 Mth 3 Mth 6-11-

Transforming Data into Action Data and model insights are translated into business actions through the incorporation of model output into business rules. Score Business rules Claims data (e.g. claim, medical, claimant) 92 Fracture Foot Reason messages Assign all claims with score >80 to Tier 4 adjusters Internal data (e.g. Insured ) CPM Distance from home to work indicates higher exposure Insured has negative financial management experience Number of prior claims indicates a higher exposure Refer all claims with score > 75 and 3+ red flag reason messages to SIU Investigator Impact variables External data (e.g. census, demographic, insured, financial strength, household) 45 miles to work 5 prior claims -14- Poor insured financial stress score Accident on weekend Assign nurse consultants to all claims scoring > 90 in Injury Group Fracture Foot
