The indicated 1/1/2018 pure premiums represent an average decrease of 9.3% from the pure premiums effective 1/1/2017. The components of this change are as follows: Experience and Benefits -9.0% Loss Based Expense -0.3% Overall -9.3% By industry group, the average pure premium level changes are: Manufacturing -11.1% Contracting -10.1% Office & Clerical -9.2% Goods & Services -9.3% Miscellaneous -6.0% Within each industry group, the changes will vary from the average classification depending upon the volume and character of the particular classification experience. Changes in certain miscellaneous rating values were made in proportion to the changes in the Michigan State Average Weekly Wage. IMPORTANT: These pure premiums are advisory. They are neither manual nor gross rates, but instead represent loss and loss adjustment costs per $100 of payroll. In accordance with the Michigan Insurance Code, the pure premiums exclude the following elements: a) Trend factors b) Profits c) Expenses, except loss adjustment expenses

CIRCULAR LETTER #296 Page 2 While provisions for general expenses; acquisition and field supervision expenses, taxes, licenses and fees, and profits and contingencies have been excluded, provisions for loss based expenses have been included. This year s pure premium analysis is based on data from the two most recent complete Policy Years (2015 & 2014). No material changes to the methodology were recognized in this year s analysis. The 5-year average for paid+case loss development factors continues to be utilized, after changing from the 3-year index effective 1/1/2015. Section C of Part III of this publication contains the indications based on several alternative methodologies, including methods using Accident Year 2016, as well as various loss development methodologies. Under Michigan s filing requirements, carriers may utilize the Data Collection Agency (DCA) pure premiums along with their own expense loadings, and they may introduce factors to consider different workers compensation experience. Carriers may introduce trend factors if they choose, and are also permitted to make their own rates completely independent of the DCA pure premiums.
