Texas Government Code - GOV'T § 803.101. Participation by Retirement Systems

(a) Except as provided by Subsections (b) and (f), each retirement system to which this chapter applies is required to participate in the program of proportionate retirement benefits provided by this chapter.

(b) A subdivision participating in the Texas County and District Retirement System or a municipality participating in the Texas Municipal Retirement System is not required to participate in the proportionate retirement program if the subdivision or municipality elected not to participate under the authority of former law and has not revoked the election under Subsection (c).

(c) A subdivision or municipality that elected not to participate in the proportionate retirement program may revoke the election and elect to participate.  An election to participate may be made by vote of the governing body of the subdivision or municipality in the manner required for official actions of the governing body.  The governing body shall send notice of an election to participate to the board of trustees of the retirement system in which the subdivision or municipality participates.

(d) The effective date of participation in the proportionate retirement program by a subdivision or municipality electing to participate under Subsection (c) is the first day of the month after the month in which the appropriate board of trustees receives notice of an election.

(e) Participation in the proportionate retirement program includes all persons who are members of a retirement system to which this chapter applies and, in the case of members of the Texas County and District Retirement System or the Texas Municipal Retirement System, who are also employees or former employees of a subdivision or municipality participating in the proportionate retirement program.

(f) The governing body of a public retirement system in this state for municipal employees that is a qualified plan under Section 401(a) of the Internal Revenue Code of 1986 (26 U.S.C. Section 401) may elect to participate in the proportionate retirement program by adopting a resolution to that effect.  A resolution may not be adopted under this subsection without the approval of the governing body of the municipality that finances the retirement system.  The governing body of the retirement system shall notify all other participating retirement systems of the election.  The effective date of participation in the proportionate retirement program by a retirement system for which an election is made under this subsection is the first day of the third month after the month in which notice is given under this subsection.  An election under this subsection does not require the approval of the participants in the public retirement system making the election.

(g) The governing body of a municipality described by Section 803.0021(1) that finances a public retirement system for police officers or firefighters may not approve the retirement system's election under Subsection (f) to participate in the proportionate retirement program unless an actuary acting on behalf of the municipality reviews the initial cost to the municipality of making the election.

(h) If the governing body of a public retirement system under Subsection (g) adopts a resolution to participate in the proportionate retirement program, the governing body of the municipality that finances the retirement system shall appropriate and pay to the retirement system, at the same time the municipality makes the municipality's monthly contribution to the retirement system, the additional amount necessary, as determined by the retirement system's actuary, to fund the additional liabilities incurred by the retirement system as a result of participating in the proportionate retirement program.
