Section 20. (a) A city, town, district, county or municipal lighting plant that accepts this section may establish an Other Post-Employment Benefits Liability Trust Fund, and may appropriate amounts to be credited to the fund. Any interest or other income generated by the fund shall be added to and become part of the fund. Amounts that a governmental unit receives as a sponsor of a qualified retiree prescription drug plan under 42 U.S.C. section 1395w-132 may be added to and become part of the fund. All monies held in the fund shall be segregated from other funds and shall not be subject to the claims of any general creditor of the city, town, district, county or municipal lighting plant.
(b) The custodian of the fund shall be (i) a designee appointed by the board of a municipal lighting plant; (ii) the treasurer of any other governmental unit; or (iii) if designated by the city, town, district, county or municipal lighting plant in the same manner as acceptance prescribed in this section, the Health Care Security Trust board of trustees established in section 4 of chapter 29D, provided that the board of trustees accepts the designation. The custodian may employ an outside custodial service to hold the monies in the fund. Monies in the fund shall be invested and reinvested by the custodian consistent with the prudent investor rule established in chapter 203C and may, with the approval of the Health Care Security Trust board of trustees, be invested in the State Retiree Benefits Trust Fund established in section 24 of chapter 32A.
(c) This section may be accepted in a city having a Plan D or Plan E charter, by vote of the city council; in any other city, by vote of the city council and approval of the mayor; in a town, by vote of the town at a town meeting; in a district, by vote of the governing board; in a municipal lighting plant, by vote of the board; and in a county, by vote of the county commissioners.

On or before June 30 of the following year, the public employee retirement administration commission shall notify any entity submitting this summary of any concerns that the commission may have or any areas in which the summary does not conform to the requirements of GASB 45 or other standards that the commission may establish.
