Board approves 2024 rates

The Board approved IMRF employer contribution rates for the 2024 calendar year. The rates, which are unique to each IMRF employer, are expressed as a percentage of payroll. The average employer contribution rate for the Regular Plan for 2024 will be 6.65%, as compared to 6.55% in 2023.

Board hears Triennial Experience study results

The report from actuary Gabriel, Roeder, Smith & Co. (GRS) compares prior actuarial assumptions to IMRF’s actual experience over a three-year period from January 1, 2020, to December 31, 2022, and considers future trends. The results of the study inform the setting of actuarial assumptions in future years. These actuarial assumptions are necessary to calculate the fund’s liabilities, and ultimately, to determine employer contribution rates.


The Demographic Assumptions include:

The Economic Assumptions include:


The actuaries recommended no change to the economic assumptions and only minor adjustments to the demographic assumptions. Overall, these assumption adjustments project to put slight downward pressure on IMRF liabilities and employer contributions in future years.


GRS actuary Mark Buis said that IMRF is a financially sound public pension system.


“The fund has performed very well,” Buis said. “With a funded status of 98%, you are the envy of all the plans in Chicagoland, if not the country.”
