(A) Overall average rate level increases or decreases, for all coverages combined, of seven percent above or below the insurer‘s current rates in effect may take effect without prior approval on a file and use basis with respect to rates for automobile insurance policies as set forth in this section. The seven percent cap does not apply on an individually insured basis. Insurers are limited to two rate increases during any twelve-month period as set forth in subsections (B) and (C).

(B)(1) Notwithstanding any other provision of this chapter, for any policies governed by this section, filings that produce rate level changes based on the limitation specified in subsection (A) become effective without prior approval; provided, that no more than one rate increase of seven percent above or below the insurer’s current rates in effect may be implemented during any twelve-month period on a file and use basis. Any other increase request is subject to prior approval. A rate increase may not be implemented until the onset of the new policy period.

(2) A rate increase or decrease falling within the limitation in subsection (A) may become effective no less than thirty days after the date of the filing with the director. The filing is considered to meet the requirements of this chapter unless the director or his designee notifies the insurer that the filing does not comply with this chapter within that thirty-day time period. If, after the filing becomes effective, the director finds the filing does not comply with the requirements of this chapter, the director shall issue a written order specifying in detail the provisions with which the insurer has not complied and state a reasonable period thereafter in which the filing is considered no longer effective. Any order by the director pursuant to this section that is issued more than thirty days from the date on which the director received the rate filing must be on a prospective basis only and may not affect any contract issued or made before the effective date of the order.

(C) Rate filings for automobile insurance also may be made outside the limitation specified in subsection (A), however those filings are subject to the prior approval of the director. The director shall approve or disapprove these filings in accordance with the provisions of §§ 38-73-960 and 38-73-990. No more than two rate increases may be implemented during a twelve-month period. If the two rate increases fall above or below seven percent as specified in subsection (B), the second rate increase request within a twelve-month period is subject to prior approval. The limitation provided in § 38-73-920 relating to the number of permissible filings within a twelve-month period does not apply to automobile filings made pursuant to the provisions of this section.

(D) Individual automobile insurance companies and member companies of an affiliated group of automobile insurers may utilize different filed rates for automobile insurance coverages in accordance with rating plans filed with and approved by the director. These rating plans may provide for different rates, rating tiers, and rating plans among affiliated companies. For the purposes of this subsection, an affiliated group of automobile insurers includes a group of automobile insurers under common ownership, management, or control.

(E) The Director of the Department of Insurance or his designee may promulgate regulations to implement the provisions of this section.

(F) This section does not apply to rate or rule filings of insurers who write only exempt commercial policies. Rate or rule filings for exempt commercial policies must comply with the requirements of S.C. Code Ann. Regs. Section 69-64, § 38-73-920, and other applicable provisions of this title.
