§ 26.1-25-04 — Rate filings

1. Every insurer shall file with the commissioner, except as to inland marine risks which
by general custom of the business are not written according to manual rates or rating
plans, every manual, minimum class rate, rating schedule or rating plan, and every
other rating rule, and every modification of any of the foregoing which it proposes to

use. Every filing must state the proposed effective date thereof and must indicate the
character and extent of the coverage contemplated. When a filing is not accompanied
by the information upon which the insurer supports the filing, and the commissioner
does not have sufficient information to determine whether the filing meets the
requirements of this chapter, the commissioner shall require the insurer to furnish the
information upon which it supports the filing and the waiting period commences as of
the date the information is furnished. Every insurer shall file or incorporate by
reference to material which has been approved by the commissioner, at the same time
as the filing of the rate, all supplementary rating and supporting information to be used
in support of or in conjunction with a rate. The information furnished in support of a
filing may include:
a. The experience or judgment of the insurer or advisory organization making the
filing.
b. Its interpretation of any statistical data upon which it relies.
c. The experience of other insurers or advisory organizations.
d. Any other relevant factors.
A filing and any supporting information is open to public inspection after the filing
becomes effective. Specific inland marine rates on risks specially rated, made by an
advisory organization, must be filed with the commissioner.
2. After reviewing an insurer's filing, the commissioner may require that the insurer's
rates be based upon the insurer's own loss and expense information. If the insurer's
loss or allocated loss adjustment expense information is not actuarially credible, as
determined by the commissioner, the insurer may use or supplement its experience
with information filed with the commissioner by an advisory organization. Insurers
utilizing the services of an advisory organization must provide with their rate filing, at
the request of the commissioner, a description of the rationale for such use, including
its own information and method of utilization of the advisory organization's information.
This chapter does not require any insurer to become a member of or a subscriber to
any advisory organization.
3. The commissioner shall review filings as soon as reasonably possible after they have
been made in order to determine whether they meet the requirements of this chapter.
4. Subject to the exceptions specified in subsections 5 and 6, each filing must be on file
for a waiting period of sixty days before it becomes effective. The period may be
extended by the commissioner for an additional period not to exceed fifteen days if the
commissioner gives written notice within the waiting period to the insurer or advisory
organization which made the filing that the commissioner needs the additional time for
the consideration of the filing. Upon written application by the insurer or advisory
organization, the commissioner may authorize a filing which the commissioner has
reviewed to become effective before the expiration of the waiting period or any
extension thereof. A filing is deemed to meet the requirements of this chapter unless
disapproved by the commissioner within the waiting period or any extension thereof.
5. A filing with respect to a competitive market commercial risk rate filing, a private
passenger automobile rate filing in which the average rate change is less than five
percent, or a homeowner rate filing in which the average rate change is less than five
percent is deemed to meet the requirements of this chapter until such time as the
commissioner reviews the filing and so long thereafter as the filing remains in effect.
Specific inland marine rates on risks specially rated by an advisory organization
become effective when filed and are deemed to meet the requirements of this chapter
until such time as the commissioner reviews the filing and so long thereafter as the
filing remains in effect.
6. An insurer must file notice of a rate change for either a competitive market commercial
risk product, a private passenger automobile rate filing in which the average rate
change is less than five percent, or a homeowner rate filing in which the average rate
change is less than five percent with the commissioner within thirty days after
implementing the rate change. The exemption provided in subsection 5 for a private

passenger automobile or homeowner rate change filing is limited to no more than one
filing per calendar year.
7. The commissioner after notice and hearing may determine by order that a commercial
risk market is noncompetitive. A rate filing for a product in a noncompetitive
commercial risk market is subject to the provisions of this chapter. The commissioner's
order finding that a commercial risk market is noncompetitive expires after two years.
8. Under any rules the commissioner may adopt, the commissioner may, by written order,
suspend or modify the requirement of filing as to any kind of insurance, subdivision, or
combination thereof, or as to classes of risks, the rates for which cannot practicably be
filed before they are used. The orders and rules must be made known to insurers and
advisory organizations affected thereby. The commissioner may make any
examination the commissioner deems advisable to ascertain whether any rates
affected by the order meet the standards set forth in subdivision e of subsection 1 of
section 26.1-25-03.
9. Upon the written application of the insured, stating the insured's reasons therefor, filed
with and approved by the commissioner, a rate in excess of that provided by a filing
otherwise applicable may be used on any specific risk.
10. No insurer may make or issue a contract or policy except in accordance with the filings
that have been approved and are in effect for the insurer as provided in this chapter or
in accordance with subsection 8 or 9.
11. Nothing in this chapter may be construed to require an advisory organization or its
members or its subscribers to immediately refile final rates or premium charges
previously approved by the commissioner. Members or subscribers of an advisory
organization are authorized to continue to use insurance rates or premium charges
approved before July 1, 1991, or decreases from those rates or premium charges filed
by the advisory organization and subsequently approved after July 1, 1991.
