(a) As provided in this section, the purpose of the pension stabilization reserve trust fund is to protect the participants and beneficiaries of the Hybrid Retirement Plan for State Employees and Teachers from a reduction or loss of benefits through the implementation of the cost controls contained in § 8-36-922(c)(1)(C)-(G) or in § 8-36-922(d)(1). If in any given year, the total amount in an employer's employer reserve account established pursuant to § 8-36-920(e) is not sufficient to meet the actuarial liabilities for which the employer's employer reserve account was created, then the board of trustees of the Tennessee consolidated retirement system shall certify to the trustees of the trust the amount necessary to fund current benefits as determined by the actuarial valuation performed by the retirement system's actuary. Upon receipt of the certification, the trustees of the trust shall determine whether transferring all or a portion of the requested amount from the employer's stabilization reserve trust account to the applicable employer reserve account of the employer would be in the best interests of the trust beneficiaries. If it is, the trustees shall direct the treasurer to transfer such amount as the trustees shall determine from the employer's stabilization reserve trust account to the applicable employer reserve account of the employer.

(b) The assets of the pension stabilization reserve trust fund shall be used exclusively for the purpose set forth in this section and to pay the reasonable expenses incurred in administering and investing the trust assets.
