Tex. Ins. Code § 1105.057

Notwithstanding any provision of this code to the contrary, as to a policy to which this subchapter applies, a refiling of nonforfeiture values or of the method of computing nonforfeiture values for a previously approved policy form that involves only a change in the interest rate or mortality table used to compute nonforfeiture values does not require refiling of any provision of the policy form.
