PRIOR APPROVAL OF CERTAIN RATE INCREASES OR DECREASES. (a) An insurer shall file with the department for the commissioner's approval a rate for commercial or residential property insurance or commercial or personal automobile insurance, supplementary rating information, and any supporting information in accordance with this subchapter if the insurer's rate increased or decreased by more than 10 percent from the insurer's previously filed rate that is in effect on the date of the filing.

(c) For purposes of this section, a rate is filed with the department on the date the department receives the rate filing. SECTION 2. Section 2251.152(b), Insurance Code, is amended to read as follows: (b) Notwithstanding Subsection (a), after a rate filing required under Section 2251.151 is approved under this subchapter, an insurer, without prior approval of the commissioner, may use any rate subsequently filed by the insurer if the subsequently filed rate does not exceed the lesser of: (1) 107.5 percent of the rate approved by the commissioner; or (2) 110 percent of any rate used by the insurer in the previous 12-month period. SECTION 3. Section 2251.153(b), Insurance Code, is amended to read as follows: (b) Except as provided by Subsection (c), if a rate has not been approved or disapproved by the commissioner before the expiration of the 30-day period described by Subsection (a), the rate is considered approved and the insurer may use the rate unless the rate proposed in the filing represents an increase of 10 [12.5] percent or more from the insurer's previously filed rate.
