     (b) The board shall deposit the amount calculated in subsection (2)(a) in a reserve fund.
     (3) Subject to the restrictions contained in subsections (4) and (5), the board shall annually use 90% of the amount in the reserve fund provided for in subsection (2)(b) to pay a postretirement adjustment to eligible retirees or beneficiaries under 19-20-713.
     (4) If the amount in the reserve fund is insufficient to provide an average monthly postretirement adjustment of at least $1 under 19-20-713, an adjustment may not be made in that calendar year.
     (5) The amount available for payment of the postretirement allowance is limited to an amount that would provide a percentage increase in the average service, disability, or survivorship allowance of all eligible retirees, when combined with the postretirement adjustment, that is equal to or less than the percentage increase for the previous calendar year in the annual average consumer price index for urban wage earners and workers compiled by the bureau of labor statistics, United States department of labor, or its successor agency.
