Actuarial Assumptions—The total pension liability as of the measurement date was determined by
using an actuarial valuation as noted in the table below, with update procedures used to roll forward
the total pension liability to the measurement date. The actuarial valuations used the following
actuarial assumptions presented below:
  ERS
  Measurement date  March 31, 2025
  Actuarial valuation date  April 1, 2024
  Interest rate  5.90%
  Salary scale  4.30%
  Decrement tables  April 1, 2015-
  March 31, 2020
  Inflation rate  2.9%
  Cost-of-living adjustments  1.5%

Demographic assumptions used in the April 1, 2024 actuarial valuation are based on the results of an
actuarial experience study completed April 1, 2020 for the period April 1, 2015 – March 31, 2020.
Annuitant mortality rates are adjusted to incorporate mortality improvements under the Society of

combined to produce the long-term expected rate of return by weighting the expected future real rates
of return by each the target asset allocation percentage and by adding expected inflation. The best
