3 2018 Classification Relativities Preliminary Draft Relativities will underlie proposed January 1, 2018 advisory pure premium rates Almost 100% of policy year experience included Data from one insolvent insurer excluded Methodologies generally consistent with 1/1/17 Filing Reflects class definition changes resulting from research studies adopted by Committee at 4/25/17 meeting Reflects adjustment for wage level changes by classification reviewed at 3/14/17 meeting Reflects updates to Retro Hazard Groups for 2018 Preliminary draft does not include (will be reflected for filing): Adjustment for approved July 1, 2017 pure premium rates Some data corrections in response to queries received after draft date 3

4 Classification Relativities Summary of Process Reflects changes in classification s pure premium rate relative to statewide average (relativity changes balance to 0%) Based on unit statistical data on losses and payroll by classification Through policy year 2014 Data subject to series of data quality controls Excludes data of insolvent insurers Principal components of computation Expected loss to payroll ratios Adjusted (actual) loss to payroll ratios Selected loss to payroll ratios 25% change limitation 4

5 Expected Loss to Payroll Ratios Reflects loss component of approved January 1, 2017 pure premium rate change Adjustments Large loss limitation ($500,000 per claim) Change in industrial sector average relativity 5

6 Adjusted (Actual) Loss to Payroll Ratios Based on 2, 3, 4, or 5 years of experience Adjusted payroll computation (new for 2018) Wage level changes through PY 2018 adjusted on a relative basis Includes projected wage inflation and minimum wage changes No change in total payroll level Adjusted losses computation Development to ultimate Current benefit level (new for 2018: includes impact of wage inflation on indemnity benefit levels) Earlier years adjusted to current years average losses (new for 2018: factors also applied to latest two years losses) Large loss limitation ($500,000 per claim) Overall expected level of experience 6

7 Selected Loss to Payroll Ratios Combination of adjusted (actual) and expected loss to payroll ratios Credibility Full credibility standards based on claim counts and average claim size Classification s credibility based on total expected losses for years used in computation of classification relativities Full credibility Expected loss to payroll ratio not used in computation 7
