Current through Register Vol. 49, No. 13, September 23, 2024
Subpart 1.
Use of deviated rates.
A. If the
loss ratio of the insurer is 55 percent or more based on the most recent one to
three calendar years' experience using the prima facie rates currently in use
for any plan of coverage, the insurer may file for approval and use rates that
are higher than those prima facie rates, reflecting the anticipated difference
in claim cost.
B. If the loss ratio
of the insurer is less than 42.5 percent based on the most recent three
calendar years' experience using the prima facie rates currently in use for any
plan of coverage, the insurer shall file for approval and use rates for that
plan of coverage that are lower than prima facie rates, reflecting the
anticipated difference in claim cost.
C. If deviated rates are to be filed under
item A or B, the insurer may file rates for approval that will be:
(1) applied uniformly to all accounts of the
insurer; or
(2) applied on an
equitable basis approved by the commissioner to only one or more accounts of
the insurer for which the experience has been more favorable or less favorable
than expected.
For purposes of determining deviated rates under this subpart,
rates for monthly premium plans may be determined separately for open-end and
closed-end credit accounts.
Subp. 2.
Use of rates for
accounts.
An insurer, by written notice to the commissioner of its
election to do so, may file and use premium rates to be used to rate one or
more of its accounts in this state.
A.
An insurer may use a rate for an account not greater than the account rate as
follows.
(1) The actual loss ratio (ALR) is
the prima facie loss ratio of the account being filed for any plan of coverage.
It is the ratio of the actual incurred claims to the premiums based on current
prima facie rates.
(2) The
credibility factor (Z) is determined from the table in item D.
(3) The credibility adjusted loss ratio (CLR)
is calculated using the following formula where PFLR is the loss ratio from
part
2760.0040:
CLR = [ALR * Z] + [PFLR * (1-Z)]
(4) The account rate (AR) is calculated
according to the following formula, where PFR is the prima facie rate, and the
result is rounded to two decimal places:
AR = PFR * [1 - PFLR * (1-(CLR/PFLR))]
(5) The requested rate will be equal to the
previous account rate if the new account rate calculated by the formula in
subitem (4) is within five percent of the previous account rate. Otherwise, the
requested rate will be equal to the new account rate calculated by the formula
in subitem (4).
B. An
account rate will be in effect for a period of time not longer than five years.
An insurer may file for a new account rate before the end of an account rate
period, but not more often than once during any 12-month period.
C. If a creditor changes insurers, the
account rate established under this part in effect for the account on the date
of the change will continue to be in effect for the account with the succeeding
insurer for the remainder of the account rate period or until a new account
rate for this account is established.
