Tex. Insurance Code § 884.453

(a) On the effective date of a direct reinsurance agreement under Subchapter L, the stipulated premium company shall compute:

(1) the amount of the reserves required under this chapter on the policies assumed under the agreement; and

(2) the amount of the net assets transferred to the stipulated premium company under the agreement.

(b) If the amount of the net assets transferred is not equal to the amount of the required reserve, the difference shall be designated and carried as a deficiency reserve. The deficiency reserve does not create insolvency of the stipulated premium company if the company, beginning with the first calendar year that begins after the effective date of the direct reinsurance agreement, reduces the computed deficiency amount, including interest at the assumed rate, by at least 10 percent during each year as computed on December 31 of that year. The reduction must result in the deficiency reserve being eliminated on December 31 of the year for which the 11th annual statement is filed after the company enters into the direct reinsurance agreement. The required reduction in the deficiency reserve may not exceed the cumulative aggregate amount of 10 percent a year.

(c) If in any year a stipulated premium company has not reduced its deficiency reserve as required by Subsection (b), the company's board of directors by appropriate action shall increase premium rates by advancing the age of each insured at the date the insured's policy is issued or otherwise equitably adjust premium rates to correct that failure. The board shall take that action not later than the 30th day after the date the reserves are computed.

(d) If the board does not comply with Subsection (c), the stipulated premium company is considered to be insolvent for purposes of this chapter.
