MT CSI Advisory Memorandum of 2007-08-29
House Bill 587 (HB) - Amending Section § 33-23-204, Mont. Code Ann., Limitation of Liability Under Motor Vehicle Liability Policy ("Anti- Stacking Statute")
Instructions For Filing Rates
For UM, UIM and Med-Pay Coverages
House Bill 587 (effective April 17, 2007) allows insurers to avoid “stacking”
(combining in the aggregate) of Uninsured Motorists [UM], Underinsured
Motorists [UIM] and Medical Payments [Med-Pay] coverages provided the rates
are filed with the Commissioner of Insurance and “reflect the limiting of coverage
separately to the vehicles covered.” (See 33-23-203, Montana Code Annotated,
as amended in 2007.)
Insurers filing rates under the new law must provide the following
information, including an actuarial certification and supporting actuarial
documents, with their rate filings. This checklist with appropriate answers must
be completed by all insurers filing rates for UM, UIM and Med-Pay whether the
insurer intends to allow “stacking” or not. [Note that new policy forms stating that
coverage will be limited (not stacked) would also need to be filed with the
Commissioner separately.]
I. Is this rate filing in connection with UM, UIM or Med-Pay coverages and
is “stacking” allowed?
A. Does this submission contain UM, UIM or Med-Pay coverage rates?
___ Yes ___ No (If the answer is “No,” disregard the remainder of this
checklist and send the checklist in with “No” marked above only. If the answer is
“Yes,” continue.)
B. Does the company allow BOTH the “stacking” and “non-stacking” of
UM, UIM and Med-Pay limits?
___ Yes
___ No (If the answer to this question is “Yes,” please go to Section II.
of the checklist and provide the information requested there for the non-stacked
rates/premiums only)
C. Does the company allow the “stacking” only of UM, UIM and Med-Pay
limits?
___ Yes
___ No (If the answer to this question is “Yes,” disregard the
remainder of this checklist and send in the checklist with a response to these first three
inquiries only. If the answer is “No,” continue to section II. of the checklist and provide
the information requested there for the non-stacked rates/premiums.)
II. Information required for rate filings when “stacking” is not allowed.
A. Provide a complete copy of UM, UIM and Med-Pay premiums and/or
rates and a complete copy of the premiums and/or rates that are being

premiums charged actuarially reflect the limiting of coverage separately to
the vehicles covered by the policy per 33-23-203 (1)(c), MCA (2007).
C. Provide actuarial supporting documentation, assumptions and work
papers as to how the rates and/or premiums are derived.

or is there a separate policy covering each vehicle?
