Amend CSSB 1007 (Senate committee printing) by inserting the following appropriately numbered SECTIONS and renumbering existing SECTIONS of the ARTICLE accordingly: SECTION 4.__. Section 2253.001(b), Insurance Code, is amended to read as follows: (b) The commissioner by rule may allow a greater rate difference than the rate difference specified by Subsection (a) only if the commissioner determines that the greater rate difference is justified solely by weather-related factors and is supported with sound actuarial data. SECTION 4.__. Section 2253.001(b), Insurance Code, as amended by this article, applies only to a residential property or personal automobile insurance policy delivered, issued for delivery, or renewed on or after January 1, 2010. A policy delivered, issued for delivery, or renewed before January 1, 2010, is governed by the law in effect immediately before the effective date of this Act, and that law is continued in effect for that purpose.
