CITY OF ROSEVILLE, MINNESOTA NOTES TO FINANCIAL STATEMENTS December 31, 2016 Salary increases were based on a service-related table. Mortality rates for active members, retirees, survivors, and disabilitants were based on RP-2000 tables for males or females, as appropriate, with slight adjustments. Benefit increases for retirees are assumed to be 1% effective every January lst through 2026 and 2.5% thereafter. Actuarial assumptions used in the June 30, 2016 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 2015. The experience study for Police and Fire Plan was for the period July 1, 2004 through June 30, 2009. The following changes in actuarial assumptions occurred in 2016: General Employees Fund • The assumed post-retirement benefit increase rate was changed from 1.0% per year through 2035 and 2.5% per year thereafter to 1.0% per year for all future years. • The assumed investment return was changed from 7.9% to 7.5%. The single discount rate was changed from 7.9% to 7.5%. • Other assumptions were changed pursuant to the experience study dated June 30, 2015. The assumed future salary increases, payroll growth, and inflation were decreased by 025% to 3.25% for payroll growth and 2.50% for inflation. Police and Fire Fund • The assumed post-retirement benefit increase rate was changed from 1.0% per year through 2037 and 2.5% thereafter to 1.0% per year for all future years. • The assumed investment return was changed from 7.9% to 7.5%. The single discount rate changed from 7.9% to 5.6%. • The assumed future salary increases, payroll growth, and inflation were decreased by 0.25°/o to 3.25% for payroll growth and 2.50% for inflation. 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: 67
