Modifies provisions relating to retirement systems

HB 2782 modifies rules for certain Missouri state retirement systems regarding new benefits and funding. It prohibits adding new retirement benefits or cost-of-living adjustments that would increase the system's financial burden unless the plan's funding ratio meets strict thresholds (at least 80% before, 75% after adoption). The bill specifically authorizes a one-time supplemental payment of up to $2,000 per month to eligible retirees under the system governed by sections 169.410-169.542, payable by September 30, 2027, subject to state funding. This payment is in addition to regular pension benefits and requires state appropriation. The law does not apply to retirement systems under chapters 70 or 476.
