HB 2870 would authorize a city or town with a population of 500,000 or more that provides a retirement, disability, and death benefit system under this section to require each member of the system to contribute an amount that may exceed 10 percent of the annual compensation paid to the member by the city or town as determined by the city or town. If the member contribution were increased with no change to benefits, the funding status of the retirement fund would improve. To the extent the city or town contributions increases its matching contribution, the funding status would further improve. No plan details were provided as to current benefits or funding needs, nor were explicit proposals for increases in contributions provided. Hence the sole actuarial impact of the bill would be an improvement in any affected plan's funding status, with likely reductions in amortization periods.
