(S) Any other commercial lines insurance coverage or risk that the commissioner may, by order, exempt from rate filing and approval requirements in order to promote enhanced competition or to more effectively use the resources of the department that might otherwise be used to review commercial lines filings or because the commissioner does not consider the filing and approval requirements to be necessary or desirable for the protection of the public.

The finding of fact by the commissioner must specify the relevant tests used to determine whether a lack of a reasonable degree of competition exists and the results thereof. In the absence of such findings of fact by the commissioner, a competitive market is presumed to exist.

(b) Every filing shall state the proposed effective date and shall 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 article, he or she shall require the insurer to furnish the information upon which it supports the filing and in that event the waiting period shall commence as of the date the information is furnished. The information furnished in support of a filing may include: (1) The experience or judgment of the insurer or rating organization making the filing; (2) the experience or judgment of the insurer or rating organization in the territorial rate areas established by §33-20-3(c)(2) of this code; (3) its interpretation of any statistical data it relies upon; (4) the experience of other insurers or rating organizations; or (5) any other relevant factors. A filing and any supporting information is open to public inspection as soon as the filing is received by the commissioner. Any interested party may file a brief with the commissioner supporting his or her position concerning the filing. Any person or organization may file with the commissioner a signed statement declaring and supporting his or her or its position concerning the filing. Upon receipt of the statement prior to the effective date of the filing, the commissioner shall mail or deliver a copy of the statement to the filer, which may file a reply as it may desire to make. This section is not applicable to any memorandum or statement of any kind by any employee of the commissioner.

Upon written application by an insurer or rating organization, the commissioner may authorize a filing which he or she has reviewed to become effective before the expiration of the waiting period. A filing shall be deemed to meet the requirements of this article unless disapproved by the commissioner within the waiting period.

(f) Any special filing with respect to a surety bond required by law or by court or executive order or by order, rule, or regulation of a public body, not covered by a previous filing, shall become effective when filed and shall be deemed to meet the requirements of this article until the commissioner reviews the filing and so long thereafter as the filing remains in effect.

(g) Specific inland marine rates on risks specially rated by a rating organization shall become effective when filed and shall be deemed to meet the requirements of this article until the commissioner reviews the filing and so long thereafter as the filing remains in effect.

The commissioner may request additional information to ensure compliance with applicable statutory standards, but if the commissioner does not disapprove the filing within the initial 30-day period after receipt, the rate filing will become effective upon first usage after filing: Provided, That the commissioner may at any time thereafter, after notice and for cause shown, disapprove any rate filing.

(i) Under legislative rules, 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. These orders and rules shall be made known to insurers and rating organizations affected thereby. The commissioner may make any examination he or she may consider advisable to ascertain whether any rates affected by an order meet the standards set forth in §33-20-3(b) of this code.

(j) Upon the written application of the insured, stating his or her 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 risks.

(k) No insurer shall make or issue a contract or policy except in accordance with the filings which are in effect for that insurer as provided in this article. This subsection does not apply to contracts or policies for risks as to which filings are not required.

(l) In instances when an insurer files a request for an increase of automobile liability insurance rates in the amount of 15 percent or more, the Insurance Commissioner shall provide notice of the increase with the Office of the Secretary of State to be filed in the State Register and shall provide interested persons the opportunity to comment on the request up to the time the commissioner approves or disapproves the rate increase.
