City of Orono, Minnesota Notes to the Financial Statements December 31, 2022 Note 4: Defined Benefit Pension Plans - Statewide (Continued) E. Long -Term Expected Return on Investment 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: Asset Class Target Allocation Long-Term Expected Real Rate of Return Domestic Equity 33.5% 5.10% International Equity 16.5% 5.30% Fixed Income 25.0% 0.75% Private Markets 25.0% 5.90% Total 100% F.Actuarial Assumptions The total pension liability in the June 30, 2022, actuarial valuation was determined using an individual entry-age normal actuarial cost method: The long-term rate of return on pension plan investments used in the determination of the total liability is 6.5 percent. This assumption is based on a review of inflation and investments return assumptions from a number of national investment consulting firms. The review provided a range of return investment return rates deemed to be reasonable by the actuary. An investment return of 6.5 percent was deemed to be within that range of reasonableness for financial reporting purposes. Inflation is assumed to be 2.25 percent for the General Employees Plan and 2.25 percent for the Police and Fire Plan. Benefit increases after retirement are assumed to be 1.25 percent for the General Employees Plan. The Police and Fire Plan benefit increase is fixed at 1.00 percent per year and that increase was used in the valuation. Salary growth assumptions in the General Employees Plan range in annual increments from 10.25 percent after one year of service to 3.0 percent after 27 years of service. In the Police and Fire Plan, salary growth assumptions range from 11.75 percent after one year of service to 3.0 percent after 24 years of service. Mortality rates for the General Employees Plan are based on the Pub -2010 General Employee Mortality Table. Mortality rates for the Police and Fire Plan is based on the Pub-2010 Public Safety Employee Mortality tables. The tables are adjusted slightly to fit PERA’s experience. Actuarial assumptions used in the June 30, 2022 valuation were based on the results of actuarial experience studies. The most recent four-year experience study in the General Employees Plan was completed in 2019. The assumption changes were adopted by the Board and become effective with the July 1, 2020 actuarial valuation. The most recent four-year experience study for the Police and Fire Plan was completed in 2020 were adopted by the Board and became effective with the July 1, 2021 actuarial valuation. 78 124
