Massachusetts Workers' Compensation
The Commissioner of Insurance first issued general
instructions, known as the Massachusetts Workers’ Compensation
Statistical Plan, on January 2, 1929, for the preparation and
filing of experience with The Workers’ Compensation Rating
and Inspection Bureau of Massachusetts on all policies effective
in Massachusetts on and after January 1, 1929. The plan has been
reprinted in amended form and supplemented by circular letters
from time to time.
On June 30, 2000 the Massachusetts Commissioner of Insurance ordered
that effective immediately the Commissioner’s Statistical
Plan shall consist of two components, first the unit statistical
data and second the aggregate financial data.
The instructions and definitions for the reporting of unit statistical
data are contained in the “Part I – Unit Statistical
Reporting” portion of the Statistical Plan. The instructions,
definitions, and sample forms for the reporting of aggregate financial
data are contained in the “Part II – Aggregate Financial
Reporting” portion of the Statistical Plan.
Any future changes in the instructions or amendments of the rules
of this plan will be made by means of reprinted pages. Changes
will be indicated by bold italic print with a Times New Roman
font. Elimination of text will be indicated by a shaded area.
The Statistical Plan is reprinted and approved by the Massachusetts
Commissioner of Insurance.
Self-Insured Groups report unit statistical data under Part I
of this plan, but are not required to report the aggregate financial
data under Part II of this plan.
