Rhode Island's pension system is one of the most underfunded in the United States, in aggregate terms. (At the time of Pew's report, the state had complete financial data on its pension systems only through 2005.) Rhode Island requires a higher contribution from state employees (8.75% of salary) to participate in the pension system than all but two other states. But it has had a good record of making its annual required contributions as determined by its own actuaries. As for non-pension benefits, adjusting for the state's size, Rhode Island's bill coming due for retiree health care and other benefits appears to be lower than most other New England states.
