28 Tex. Admin. Code § 4.2310
For the purposes of this subchapter, an appropriate buyer's guide is the latest version of the buyer's guide adopted by the National Association of Insurance Commissioners (NAIC) that applies to the particular type of annuity (such as fixed deferred annuity, equity-indexed annuity, or variable annuity) that is the subject of the transaction. If the NAIC has not adopted a buyer's guide for equity-indexed annuities, then the appropriate buyer's guide is the Buyer's Guide to Fixed Deferred Annuities that has been most recently adopted by the NAIC. If the NAIC has not adopted a buyer's guide for variable annuities, then no buyer's guide is required until one year after the date on which this subchapter becomes effective. If the NAIC has not adopted a buyer's guide for variable annuities within one year after the date on which this subchapter becomes effective, then for purposes of this subchapter the appropriate buyer's guide is the latest version of the Securities and Exchange Commission (SEC) Office of Investor Education and Advocacy "Variable Annuities: What You Should Know," SEC Pub. 011.
