CITY OF ELK RIVER NOTES TO BASIC FINANCIAL STATEMENTS YEAR ENDING DECEMBER 31, 2016 NOTE 12 POST EMPLOYMENT BENEFITS OTHER THAN PENSIONS (CONTINUED) D. Actuarial Methods and Assumptions (Continued) The remaining amortization period at December 31, 2015 was over no more than thirty years. For the URHP, the following simplifying assumptions were made: Retirement age for active employees — Based on the historical average retirement age for the covered group, active plan members were assumed to retire at age 60, or at the first subsequent year in which the member would qualify for benefits. Participation Rate — It is assumed that 10% of active participants continue coverage until age 65. Participants are assumed to continue in their current coverage type (single or family). It is assumed that 100% of retirees will continue their current coverage until age 65. Life Expectancy — Life expectancies were based on mortality tables from the National Center for Health Statistics. The 2000 United States Life Tables for Males and for Females were used. Turnover — Non -group -specific age -based turnover data from GASB Statement 45 were used as the basis for assigning active member a probability of remaining employed until the assumed retirement age and for developing an expected future working lifetime assumption for purposes of allocating to periods the present value of total benefits to be paid, Healthcare cost trend rate — The expected rate of increase in healthcare insurance premiums was based on projections of the Office of the Actuary at the Centers for Medicare & Medicaid Services. A rate of 7.5% initially, reduced to an ultimate rate of 5% after eight years, was used. Health insurance premiums — 2014 health insurance premiums for retirees were used per the valuation report. Withdrawal — The probability that an employee will remain employed until the assumed retirement age was determined using non -group specific age -based turnover data provided in Table 1 in Paragraph 35b of GASB 45. Actuarial Method — Projected Unit Credit with 30 -year amortization of the unfunded liability. For the URHP, a discount rate of 4% was used based on the historical and expected returns of the Utilities' short-term investment portfolio. In addition, a simplified version of the entry age actuarial cost method was used. The unfunded actuarial accrued liability is being amortized as a level dollar amount over an open basis. The remaining amortization period at December 31, 2015 was thirty years. BE
