(a) The commissioner shall assign a rating to each certified reinsurer after giving due consideration to the financial strength ratings assigned by rating agencies recognized by the commissioner by rule.
(b) The commissioner shall publish a list of the ratings assigned under this section for all certified reinsurers.

(c) A certified reinsurer shall secure obligations assumed from ceding insurers domiciled in the United States in accordance with the rating assigned by the commissioner under Subsection (a) and with the amount of security required by the commissioner by rule.
(d) For a domestic ceding insurer to qualify for full financial statement credit for reinsurance ceded to a certified reinsurer, the certified reinsurer must maintain security:
(1) in a form acceptable to the commissioner and consistent with the insurance laws of this state; or
(2) in a multibeneficiary trust in accordance with Subchapter D, except as otherwise provided.
(e) If a certified reinsurer maintains a trust under Subchapter D to secure its obligations, and chooses to secure its obligations incurred as a certified reinsurer with a multibeneficiary trust, the certified reinsurer shall maintain separate trust accounts for the obligations incurred under reinsurance agreements the certified reinsurer issued or renewed with reduced security as permitted by this section or comparable laws of other United States jurisdictions and for its obligations subject to Subchapter D. It is a condition to the grant of certification under § 493.1033 that the certified reinsurer has bound itself, by the language of the trust agreement and agreement with the insurance commissioner or other chief insurance regulatory official with principal regulatory oversight over each trust account, to fund, on termination of the trust account, out of the remaining surplus of the trust any deficiency of any other trust account described by this subsection.
(f) The minimum trusteed surplus requirements provided in Subchapter D do not apply to a multibeneficiary trust described by this section, except that the trust shall maintain a minimum trusteed surplus of $10 million.
(g) With respect to obligations incurred by a certified reinsurer under this section, if the security is insufficient, the commissioner:
(1) shall reduce the allowable credit by an amount proportionate to the deficiency; and
(2) may impose further reductions in allowable credit on finding that there is a material risk that the certified reinsurer’s obligations will not be paid in full when due.
(h) For purposes of this section, a reinsurer whose certification has been revoked, suspended, or voluntarily surrendered or whose certification status has become inactive for any reason shall be treated as a reinsurer required to secure 100 percent of its obligations, except that if the commissioner continues to assign to the reinsurer a higher financial strength rating as permitted by this section, the security requirement does not apply to a reinsurer whose certification has been suspended or whose certification status has become inactive.
