PERSONAL AUTOMOBILE INSURANCE RATE FILINGS
Bulletin PC-68 supersedes previous Connecticut Insurance Department Bulletin PC-36, December 20, 2000,
regarding filing and ratemaking procedures for personal automobile insurance. This bulletin describes the
information that must be included in every personal automobile rate filing. Pursuant to Conn. Gen. Stat. §38a
389, base rates for bodily injury liability and uninsured/underinsured motorist coverage are subject to prior
approval unless included in a "flex" filing (see Bulletin PC- 67).
Effective January 1, 2011, Conn. Gen. Stat. §38a-686 as amended by Public Act 10-7, mandates that certain
expenses be allocated as flat dollar amounts to base rates. Additionally, the new law requires that the flat
dollar amounts be included in the premium determination after classification factors have been applied.
Classification factors include, at a minimum, age, sex, marital status, vehicle type and model year, usage,
mileage, single v. multi-car, driving history and credit. All new and renewal policies effective on and after
January 1, 2011 must comply with this section of the public act. Section B Appendices 4 and 4A provide
procedural guidance for the calculation of flattened expense fees. Companies filing solely to comply with
P.A. 10-7 are required to submit only Appendices 2, 4 and 4A with supporting information and B(9). Other
methods of calculation of the flattened expense fees may be submitted for the Department's review.
If an insurer files rates by reference to rates charged by another insurer, as permitted by Conn. Gen. Stat.
§38a-688(a)(3), or an insurer files rates using loss costs based on reference documents previously submitted
by an advisory organization such as the Insurance Services Office, as permitted by Conn. Gen. Stat. §38a
688, then such insurers may limit the information they file to that described in Appendix 6. Filings must be
submitted through SERFF. A filing must include the following:
A.
Appendix 1: Rate Filing Summary - Supporting information must be included in the filing for all
revisions.
B.
A set of exhibits as described below:
(1) An exhibit showing indicated and adopted statewide rate level changes as a percentage of current
rates for each program by coverage. Show changes for (a) variable rate, (b) flattened expense fee,
and (c) total rate. See Appendix 2.
(2) An exhibit showing adopted rate level changes for each territory by coverage as percentages of
current rates. Combine the effect of the variable rate portion and the flattened expense fee
portion. The format should follow that shown in Appendix 3.

(3) Exhibits, showing the company's statewide rate change indications broken down by accident year
and coverage, are required. These exhibits may be in a format adapted to the company's own rate
review process as long as they contain proper adjustments to the loss experience.
(4) A set of exhibits, by coverage by territory, providing sufficient data to enable the Department to
verify that the filing complies with the requirements of PA 10-7 and this Bulletin PC-68. These
exhibits must reflect that:
(a) At least 90% of general and other acquisition expense and 100% of miscellaneous licenses,
taxes and fees are reflected in the base rates as flat dollar amounts for all territories.
(b) Individual territorial loss cost data has been moderated with reference to statewide average
loss costs by weighting the territorial indications with the statewide average 75% / 25% (i.e.
75% being the maximum weight for the individual territorial loss cost data in calculating the
territorial rate and 25% being the statewide average loss costs data). Credibility procedures
must be applied separately from 75% / 25% weighting.
Credibility, as used in actuarial ratemaking for automobile rates, is a measure of predictability
assigned to a body of loss experience. Credibility is a normal part of ratemaking. Its purpose
is not to "temper" the cost of insurance in urban territories or any other territory. The
purpose of the requirement of 75% / 25% weighting is to temper the rates in high rated urban
areas. Companies may not substitute the 75% / 25% weighting in place of credibility
formulas normally used in the ratemaking process. The weighting formulas must be used in
addition to credibility, not instead of credibility.
(5) An exhibit showing the premium dollar breakdown, identifying variable and flattened expense
portions. Include the calculation of the fixed expense fee by coverage to be applied to the base
rates after classification factors are applied. See Appendices 4 and 4A.
(6) An exhibit showing investment income as a factor of the rates, how it was calculated and an
explanation of how it was taken into consideration in the calculation of the newly filed rates.
(7) An exhibit showing, by coverage, the annual trend factors used (frequency and severity, each
separately)and the combined effect of these factors on each year of experience used in the filing.
See Appendix 5.
(8) An exhibit for each voluntary market program showing four sets of car year exposures by
territory, preferably on an earned car year basis for the most recent one-year period, for (1)
Bodily Injury, UM/UIM and Property Damage Liability coverages, (2) Medical Expense
coverage, (3) Comprehensive coverage and (4) Collision coverage. Please note the year used on
the exhibit along with the name of the program.
(9) An exhibit showing the rate order of calculation for individual premium determination.

Territorial Rating in Connecticut
1. Each rate territory is composed of one or more unique town codes. Companies may use zip codes
to determine the territory of garaging for rating automobile insurance. Companies are not
allowed to split a town or city into two territories. Company manuals must contain a rule that
states if a street divides two rating territories or towns the rate used must be that of the lower of
the two territories. Territory pages must be included with every rate filing.
2. For personal automobile insurance, the original filing of zip code conversion and any subsequent
amendments to it are subject to prior approval. Before a company adopts a system which uses zip
codes to determine rate territories, it must file a copy of the system with the Connecticut
Insurance Department. The filing must include:
(a) A table of each zip code and its corresponding rate territory.
(b) A supplementary list of those zip codes which overlap two rate territories. Companies are not
allowed to split a town or city into two territories. Company manuals must contain a rule that
states that if a street divides two rating territories or towns the rate used must be that of the lower
of the two territories.
(c) An explanation of:
(1) how your system identifies the zip code of the place of garaging versus that of mailing
address.
(2) how your system accounts for changes in zip codes as they occur.
(d) An alphabetical list of the 169 Connecticut towns with territory code.

APPENDIX 6
PERSONAL AUTO INSURANCE FILING
REQUIREMENTS FOR TWO SPECIAL CASES
A. INSURERS FILING RATES BY REFERENCE, WITH OR WITHOUT DEVIATIONS, TO RATES
FILED BY ANOTHER INSURER AND IN EFFECT, AS PERMITTED BY Conn. Gen. Stat. §3 8a
688(a)(3).
If an insurer meets the requirements outlined in Conn. Gen. Stat. §38a-688(a)(3), it may adopt the rates of
another insurer if those rates were filed and are in effect at the time of adoption. THIS SECTION DOES
NOT PERTAIN TO REFERENCE DOCUMENTS OF ADVISORY ORGANIZATIONS, such as the
Insurance Services Office ("ISO"). If an insurer uses this option, then the filing requirements outlined in
this Bulletin PC-68 apply as follows:
(a) Insurer must comply with Sections A, B(l), B(2), B(8) and B(9). Item 4 on Appendix 1 need not
be completed if the company is adopting the same rules, factors or rates used by the company it is
copying. If there is any variation for these items from those used by the company it is copying,
then the filing must identify those items and include an explanation and support for the adoption
ofthose changes.
B. REFERENCE DOCUMENTS FILED BY AN ADVISORY ORGANIZATION AS PERMITTED BY
Conn. Gen. Stat. §§38a-688 and 38a-673(c), e.g., ISO.
If an insurer uses this option, then the filing requirements outlined in this Bulletin PC-68 apply as
follows:
(1) Insurer must comply with Sections A, B(l), B(2), B(5), B(6), B(8) and B(9).
(a) B(l) and B(2) need only be completed if the Connecticut OTHER PRIVATE PASSENGER
AUTOMOBILE LIABILITY direct premiums written shown on line 19.2 on page 14 ofthe most
recently filed individual company annual statement shows more than 1 million dollars (i.e., before
rounding).
(b) If the number of earned car year exposures is extremely small, the Insurance Department will
waive completion of B(8).
(c) The filing requirement for item B(4)(b) need not be complied with if the company is adopting an
ISO loss cost that has already addressed loss cost moderation to reflect a 75/25 weighting of the
territorial loss cost with the statewide average loss cost.
