CITY OF ST. ANTHONY, MINNESOTA NOTES TO FINANCIAL STATEMENTS December 31, 2017 male rates adjusted by a factor of 0.96. The mortality improvement scale was changed from Scale AA to Scale MP-2016. The base mortality table for disabled annuitants was changed from the RP-2000 disabled mortality table to the mortality tables assumed for healthy retirees.  Assumed termination rates were decreased to 3.0% for the first three years of service. Rates beyond the select period of three years were adjusted, resulting in more expected terminations overall.  Assumed percentage of married female members was decreased from 65% to 60%.  Assumed age difference was changed from separate assumptions for male members (wives assumed to be three years younger) and female members (husbands assumed to be four years older) to the assumption that males are two years older than females.  The assumed percentage of female members electing Joint and Survivor annuities was increased.  The assumed post-retirement benefit increase rate was changed from 1.00% for all years to 1.00% per year through 2064 and 2.50% thereafter. 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: Target Long-Term Expected Asset Class Allocation Real Rate of Return Domestic Stocks 39%5.10% International Stocks 19%5.30% Bonds 20%0.75% Alternative Assets 20%5.90% Cash 2%0.00% Total 100% DISCOUNT RATE The discount rate used to measure the total pension liability in 2017 was 7.50%. 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 and the Police and Fire Fund was 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. At June 30, 2016, the Police and Fire Fund projected benefit payments to exceed the funds projected fiduciary net position after June 30, 2056 and therefore used a single discount rate of 5.6%, which as stated above, increased to 7.5% at June 30, 2017. 69
