Audit for Fiscal Year Ending June 30, 2017

CITY OF SPENCER NOTES TO FINANCIAL STATEMENTS - Continued JUNE 30, 2017

7. MUNICIPAL FIRE AND POLICE RETIREMENT SYSTEM OF IOWA (MFPRSI) - Continued

Actuarial Assumptions - The total pension liability in the June 30, 2016, actuarial valuation was determined using the following actuarial assumptions, applied to all periods included in the measurement:

3.00%.

Rate of inflation

Salary increases

4.50 to 15.00%, including inflation.

Investment rate of return

7.50%, net of investment expense, including inflation.

The actuarial assumptions used in the June 30,2016 valuation were based on the results of an actuarial experience study for the period from July 1, 2002 through June 30, 2012.

Postretirement mortality rates were based on the RP-2000 Blue Collar Combined Healthy Mortality Table with males set-back two years, females set-forward one year, and disabled individuals set– forward one year (male only rates), with no projection of future mortality improvement. The long-term expected rate of return on MFPRSI investments was determined using a building– block method in which best-estimate ranges of expected future real rates (i.e., expected returns, net of investment expense and inflation) are developed for each major asset class. These ranges are combined to produce the long-term expected rate of return by weighting the expected future real rates of return by the target asset allocation percentage and by adding expected inflation. The best estimates of geometric real rates of return for each major asset class are summarized in the following table:

Long-Term Expected Real Rate of Return

Asset Class

6.0% 5.8 7.0 8.8 6.5 9.3 8.5 9.8 3.8 6.8 2.8 6.0

Discount Rate - The discount rate used to measure the total pension liability was 7.50%. The projection of cash flows used to determine the discount rate assumed contributions will be made at 9.40% of covered payroll and the City contributions will be made at rates equal to the difference between actuarially determined rates and the member rate. Based on those assumptions, the MFPRSI's fiduciary net position was projected to be available to make all projected future benefit payments to current plan members. Therefore, the long-term expected rate of return on MFPRSI's investments was applied to all periods of projected benefit payments to determine the total pension liability.
