Elk River Municipal Utilities Elk River, Minnesota Notes to the Financial Statements December 31, 2021 Note 3: Defined Benefit Pension Plans - Statewide (Continued) The following changes in actuarial assumptions and plan provisions occurred in 2021: General Employees Fund Changes in Actuarial Assumptions The investment return and single discount rates were changed from 7.50 percent to 6.50 percent, for financial reporting purposes. The mortality improvement scale was changed from Scale MP-2019 to Scale MP-2020. Changes in Plan Provisions There were no changes in plan provisions since the previous valuation. The State Board of Investment, which manages the investments of PERA, prepares an analysis of the reasonableness on a regular basis of the long-term expected rate of return using a building-block method in which best-estimate ranges of expected future rates of return are developed for each major asset class. These ranges are combined to produce an expected long-term rate of return by weighting the expected future rates of return by the target asset allocation percentages. The target allocation and best estimates of geometric real rates of return for each major asset class are summarized in the following table: F.Discount Rate The discount rate used to measure the total pension liability in 2021 was 6.50 percent. The projection of cash flows used to determine the discount rate assumed that contributions from plan members and employers will be made at rates set in Minnesota Statutes. Based on these assumptions, the fiduciary net position of the General Employees Fund were projected to be available to make all projected future benefit payments of current plan members. Therefore, the long-term expected rate of return on pension plan investments was applied to all periods of projected benefit payments to determine the total pension liability. 45 117
