WORKERS’ COMPENSATION RATEMAKING OR HOW DO WE DO THAT ACTUARIAL THING? Senate Bill 304 Study Committee September 22, 2003 Mike Taylor State Relations - NCCI, Inc. 1
Workers’ Compensation Ratemaking • What you won’t hear • Where do we start • Where does it come from • What do we do with it • How can we be sure • Bottom line to Joe Q. Public 2
Technical Actuarial Type Words • Tail Factors • Incurred But Not Reported • On-Level Factor • Exponential Trend Factors • 18th to Ultimate Development • Composite Adjustment Factor • Off-Balance 3
What Steps Do We Take? • Look at where the state stands • Obtain new and updated data • Analyze it to see where it leads • Add in other factors • Spread it out 4
Where are we? • What’s the current status? • System changes? • Benefit Changes? • Law Changes? • Other Stuff? 5
1ST StepDetermine Overall Rate Level • How much money (premium) is needed to fund the system to only pay all the anticipated indemnity losses, medical losses and loss adjustment costs? 6
Data… • Financial Data • Calendar Year Data • Policy Year Data • How much premium did the industry bring in? 7
…and more Data • Loss Data • How much did the industry pay out? • Type of injuries • Medical costs • Wage Replacement • Frequency • Severity 8
Different data for different needs Calendar Year Data Policy Year Data Individual Policy Data 9
Calendar Year 2000 1/1/99 1/1/01 1/1/00 Consists of all transactions reported in 2000, irrespective of the years which generated them. Premium in – losses paid out Sources: NAIC, Annual Statements or AM Best 10
Calendar Year Data Advantages Readily available Fresher Compiled quickly Fixed over time Easily reconciled to other sources 11
Calendar Year Data • Drawbacks • Distorted by rapid growth or decline in market share • Greatly impacted by prior years reserve changes in current year • Not a good measure of profitability 12
Policy Year 1999 1/1/98 1/1/99 1/1/00 1/1/01 Data is organized by matching premiums and losses to policies issued during a given year, regardless of when it’s reported to insurer 13
Policy Year Data • Advantages • Matches losses & premiums to the underlying policies • More Mature • More stable 14
Policy Year Data • Drawbacks • Older • Takes too long to finalize • Not readily published 15
2nd Step - Trend • Getting from Point A • (what we are) • to Point B • (where we’re going) • Measures the changes in the growth/decline of wages and losses • Differences indicate trend 16
Cost Per Claim Going Up, Number of Claims Going Down Based on data through 12/31/00. Average indemnity and medical cost per lost-time claim. 17
Wages in Montana Are Expected to Grow Source: U.S. Department of Census. 18
Flat Trend 21
Real World 22
3rd StepAdd In The New… • Legislated benefit changes • Court decisions • New regulations 23
Impact of changes • Benefit Changes–Immediate impact on premium by higher or lower wage loss payments-Overall or by class • SB 450 • Court Decisions– Alter laws on compensabilty, coverages or benefits. Impact can be retroactive, immediate or in the future • Stavenjord • Regulations– Generally more long term in nature (safety requirements) but can have immediate effect (assessments) 24
If we continue at the same level… • Will things balance out? • Will there be enough money to pay anticipated claims? 25
4th Step - Sanity Check • Check outside sources for independent verification • DOL • WCD • OSHA • BLS • Carriers • Guy on the street 26
Determine Overall Premium Level • Add everything up to determine what the premium level needs to do • Up, down or no change +13.2% effective July 1, 2003 27
5th StepSpread Out The Changes • Not equitable to apply rate change unilaterally to all employers • 1st, Distribute to 5 Industry groups based on their experience • 2nd, Distribute to individual classifications based on their experience • Finally, Apply exceptions, caps and rules 28
6th Step -Distribute Changes to Individual Classifications • Analyze individual policy data (Unit Stat) • 5 years of experience used • Older than overall ratemaking data • 96, 97, 98, 99, 00 Policy Years • Measure for credibility • Low volume classes use national data (at Montana levels) to enhance credibility 30
Derived by Formula Pure Premium Adjustments New Proposed Loss Cost Class Ratemaking Summary times equals 31
Exceptions, Caps & Rules • Maximum change +/-25% from Industry Group indication: • Transition limits – Generally for new classes • Mandated caps by legislature, regulator or other factors 32
Loss Cost including LAE Loss Adjustment Expense Developed and Trended Losses Final Loss Cost • Add in a provision for Loss Adjustment Expense • Expenses of an insurance company which are directly chargeable to the settlement of losses such as the cost of investigating cases, defending law suits, etc. • May also include loss-based assessments 33
Full Rate Profit & Contingencies Taxes, Licen & Fees Production & General Expense Loss Adjustment Expense Developed and Trended Losses Final Manual Rate • A provision for each expense item is added by the insurer to the final loss cost to produce a full manual rate • Carrier rates expressed as a Loss Cost Multiplier • Loss cost X LCM = Final Rate 34
Policyholder Pricing Programs • Programs "tailor" the final premium to better match the characteristics of each insured • Experience rating - mandatory for risks with premium above a minimum threshold • Compares actual versus expected losses to calculate an experience modification • Premium discounts by size of policy • Reflects the fact that the relative expense of servicing large premium policies is less than that for small premium policies 35
More Policyholder Pricing Programs • Retrospective Rating • Final premium depends on the experience generated by the insured during the same time the policy is in force • Schedule rating • Premium is modified to reflect characteristics of the risk that are not reflected in the manual rate such as on-site medical facilities, safety devices, etc. • Deviations from manual rate/loss cost • Filed with the state insurance department • Carrier loss cost multiplier filings are used to build up loss costs to the final manual rate 36
Final Premium Impact • What does this mean to the average employer? • Are there other factors involved? • Growth • Change in exposure • Losses • Bottom Line: “HOW MUCH IS THIS GOING TO COST ME?” / 37
