Commissioner Andrew N. Mais today announced a thirty (30) day period of public comment on the National Council on Compensation Insurance’s (“NCCI”) voluntary loss cost and assigned risk rate filing. The Connecticut Insurance Department (“Department”) has summarized the filing and provided a link to the filing including supporting documentation. The Department does not intend to hold a public hearing concerning this filing. However, interested parties are encouraged to provide comments concerning the subject filing to the Property & Casualty Division at the address provided below or via email.

NCCI is proposing that the Department approve an overall average change of -3.0% to the current voluntary loss costs and no change to the current assigned risk rate level. The new loss costs and assigned risk rates which are the subject of this Public Notice take effect on January 1, 2023.

Reported COVID-19-related claims have been excluded from the data on which this filing is based to better reflect the conditions likely to prevail during the proposed effective period. After a comprehensive review, NCCI has determined that its general ratemaking methodologies (such as the use of the chain ladder development method, exponential trend fit model, etc.) remain appropriate for use in this year’s filing. In some areas, NCCI has made selections due to potential COVID-19 pandemic-related effects on the underlying data to better reflect the conditions likely to prevail in the filing’s proposed effective period.

The proposed change in Voluntary Market Loss Costs reflects the following loss cost level change, and the proposed change in Assigned Risk Market Rates reflects the following rate level changes:

Industry Group Voluntary Market Average
Loss Cost Level Change (%)
Assigned Risk Market Average
Rate Level Change (%)
 Manufacturing  -2.5% +0.5%
 Contracting -4.6% -1.6%
 Office & Clerical -5.3% -2.4%
 Goods & Services -2.8% +0.2%
 Miscellaneous -0.7% +2.4%
 Overall Change -3.0%   0.0%

The key components of the Voluntary Market Loss Costs and Assigned Risk Market Rate changes are comprised of the following elements:

Key Component Voluntary Market Average
Loss Cost Level Change (%)
Assigned Risk Market Average
Rate Level Change (%)
 Experience, Trend and Benefit Change
 -3.2% -3.2%
