June 10, 2016 The Board of Trustees Kent County Employees Retirement Plan and Trust Grand Rapids, Michigan Dear Board Members: The results of the 49th Annual Actuarial Valuation of the Kent County Employees Retirement Plan and Trust are presented in this report. The purpose of the annual valuation is to measure the Plan's financial progress and to determine the County's contribution rate for the ensuing fiscal year in accordance with the established funding policy. The computed contribution rate shown on page B-1 may be considered as a minimum contribution rate that complies with the Board s funding policy. Users of this report should be aware that contributions made at that rate do not guarantee benefit security. Given the importance of benefit security to any retirement system, we suggest that contributions to the Plan in excess of those presented in this report be considered. This report should not be relied on for any purpose other than those described above. It was prepared at the request of the Board and is intended for use by the Retirement Plan and those designated or approved by the Board. This report may be provided to parties other than the Plan only in its entirety and only with the permission of the Board. GRS is not responsible for unauthorized use of this report. The signing individuals are independent of the plan sponsor. The valuation was based upon information, furnished by the County, concerning retirement plan benefits, financial transactions, and individual members, terminated members, retirees and beneficiaries. Data was checked for internal and year to year consistency, but was not audited. We are not responsible for the accuracy or completeness of the information supplied by others. The date of the valuation was December 31, 2015. Future actuarial measurements may differ significantly from the current measurements presented in this report due to such factors as the following: plan experience differing from that anticipated by the economic or demographic assumptions; changes in economic or demographic assumptions; increases or decreases expected as part of the natural operation of the methodology used for these measurements; and changes in plan provisions or applicable law. This report does not contain an analysis of the potential range of such future measurements. This valuation assumed the continuing ability of the plan sponsor to make the contributions necessary to fund this plan. A determination regarding whether or not the plan sponsor is actually able to do so is outside our scope of expertise and was not performed. This report has been prepared by individuals who have substantial experience valuing public employee retirement systems. To the best of our knowledge, this report is complete and accurate and was conducted in accordance with standards of practice prescribed by the Actuarial Standards Board of the American Academy of Actuaries. The actuarial assumptions used for the valuation produce results which, individually and in the aggregate, are reasonable. C0608

Basic Financial Objective and Operation of the Retirement Plan Benefit Promises Made Which Must Be Paid For. A retirement program is an orderly means of handing out, keeping track of, and financing contingent pension promises to a group of employees. As each member of the retirement Plan acquires a unit of service credit they are, in effect, handed an "IOU" which reads: "The Employees Retirement Plan promises to pay you one unit of retirement benefits, payments in cash commencing when you retire." The principal related financial question is: When shall the money required to cover the "IOU" be contributed? This year, when the benefit of the member's service is received? Or, some future year when the "IOU" becomes a cash demand? The Constitution of the State of Michigan is directed to the question: "Financial benefits arising on account of service rendered in each fiscal year shall be funded during that year and such funding shall not be used for financing unfunded accrued liabilities." This retirement Plan meets the constitutional requirement by having the following Financial Objective: To establish and receive contributions, expressed as percents of active member payroll, which will remain approximately level from year to year and will not have to be increased for future generations of taxpayers. Translated into actuarial terminology, a level percent-of-payroll contribution objective means that the contribution rate must be at least: Normal Cost (the current value of benefits likely to be paid on account of members' service being rendered in the current year)... plus... Interest on the Unfunded Actuarial Accrued Liability (the difference between the actuarial accrued liability and current Plan assets). Kent County Employees Retirement Plan and Trust A-1

If contributions to the retirement program are less than the preceding amount, the difference, plus investment earnings not realized thereon, will have to be contributed at some later time, or, benefits will have to be reduced, to satisfy the fundamental fiscal equation under which all retirement programs must operate; that is: B = C + I - E Benefit payments to any group of members and their beneficiaries cannot exceed the sum of: Contributions received on behalf of the group... plus... Investment earnings on contributions received and not required for immediate cash payments of benefits... minus... Expenses incurred in operating the program. There are retirement programs designed to defer the bulk of contributions far into the future. The inevitable consequence is a relentlessly increasing contribution rate to a level which may be greatly in excess of the level percent-of-payroll rate. This method of financing is prohibited in Michigan by the state constitution. The accumulation of invested assets is a by-product of a level percent-of-payroll contributions, not the objective. Investment income becomes a major contributor to the retirement program and the amount is directly related to the amount of contributions and investment performance. Computed Contribution Rate Needed to Finance Benefits. From a given schedule of benefits and from the data furnished, the actuary calculates the contribution rate by means of an actuarial valuation - the technique of assigning monetary values to the risks assumed in operating a retirement Plan.

DETERMINING EMPLOYER DOLLAR CONTRIBUTIONS For any period of time, the percent-of-payroll contribution rate needs to be converted to dollars and then contributed to the Retirement Plan. The recommended procedure is: (1) at the end of each payroll period, multiply the active member payroll for the period by the employer contribution percent; and (2) promptly contribute the dollar amount so determined. Actual employer contributions for the last completed fiscal year were reported to be $8,858,387. Kent County Employees Retirement Plan and Trust B-1

Unfunded Actuarial Accrued Liabilities In financing the actuarial accrued liabilities, the valuation assets of $794,741,438 were distributed as shown below. Please see page C-13 for information concerning the derivation of valuation assets. Valuation assets were applied against actuarial accrued liabilities to determine unfunded actuarial accrued liabilities as follows: Retired Lives Active & Inactive Members Total Computed Actuarial Accrued Liabilities and Reserves $ 415,851,853 $399,686,924 * $815,538,777 Valuation Assets 415,851,853 378,889,585 794,741,438 Unfunded Actuarial Accrued Liabilities $ NONE $ 20,797,339 $ 20,797,339 * Includes accumulated member contributions.

Comments, Recommendation and Conclusion Comment A: Overall experience was more favorable than assumed experience during 2015, with a net gain from all sources of $2.1 million (approximately 0.30% of the actuarial accrued liability at the beginning of the year, as shown on page B-3). The primary reason for the gain was higher than expected return on assets phased in from prior years, offset by liability losses due to higher salary increases and lower withdrawal than expected. The Retirement Plan s valuation liabilities exceed recognized valuation assets by $20.8 million for funding purposes. Due to the Board s use of a four-year smoothed market asset valuation method, lower than expected market returns were only 25% recognized, and combined with the scheduled phase-in of the prior three years unrecognized investment income. As a result, the market value of assets returned 0.3% in 2015 while the return on valuation assets was 8.9%. The ratio of the funding value of assets to the market value of assets increased from 94.5% last year to 102.5% this year. The ratio of the funding value of assets to actuarial accrued liabilities decreased from 100.4% last year to 97.4% this year. The ratio of the market value of assets to actuarial accrued liabilities decreased from 106.3% last year to 94.7% this year. Comment B: Given annual investment returns of 7.00% going forward, a net investment gain is scheduled for the next year and investment losses are scheduled for the second and third years (see page C-13 for further details.) Over time, this will exert upward pressure on computed County contribution rates and downward pressure on the funded ratio in absence of future gains. If the computed employer contribution of 9.57% (see page B-1) had been determined using the market value of assets rather than the funding value of assets, the computed employer contribution rate would have been 10.95%. Comment C: In 2003, all retirees or spouses retired prior to 1991 received a one-time ad-hoc cost-ofliving increase ranging between 10% and 25%. This was in addition to the regular cost-of-living adjustment granted each January. This increased the County s computed contribution rate by 0.11% of active member payroll in this report and is reflected as a separate line item on page B-1. Comment D: The following figures form the basis for the Variable Employee Contribution Rate, representing aggregate Normal Cost and Unfunded Liability for all plan members, including only the 1% Post-Retirement Cost-of-Living Adjustment that has applied for all plan members since January 1, 1976. Total Normal Cost of Benefits = 17.50% Unfunded Actuarial Accrued Liabilities = 0.00% This lowered the weighted average Member contribution rate shown on page B-1 by 0.40% to 9.81% of payroll. Kent County Employees Retirement Plan and Trust B-6

Comments, Recommendation and Conclusion Comment E: The base variable portion of employee contribution rates for the plan year beginning January 1, 2017 has been determined to be 8.50% for POAM/KCLEA. Effective January 1, 2017, the member contribution rate ceiling will increase from 8.50% to 9.50% for Lieutenants and Captains, KCDSA, Management Pay Plan, Judges, Elected Officials and Commissioners, Circuit Court Referees, Airport Command Officers Association, Teamsters-Parks, Teamsters-PHN, Prosecuting Attorneys, Attorney Referees, UAW General, UAW Courts/TPOAM, and Court Reporters. Comment F: The December 31, 2015 actuarial valuation includes an update to the mortality assumption using the RP-2014 Mortality Tables with 2-dimensional, fully generational improvements projected with the MP-2015 Mortality Improvement Scales as adopted by the Board. The effect of this change increased the computed employer contribution rate. Benefit provision changes have been reflected in the valuation as well. Effective January 1, 2016, the Non-Duty Disability benefit provision of the Pension Plan will be replaced with an insured Long Term Disability (LTD) Program for the following groups: Airport Command Officers, Circuit Court Referee Association, Management Pay Plan, Teamsters PHN, UAW General, Prosecuting Attorneys, Court Reporters, and Teamster Parks (effective March 1, 2016). This change was partially reflected in the December 31, 2014 valuation. The effect of this change slightly decreased the computed employer contribution rate. The net impact of all changes increased the computed employer contribution rate by 1.93%. Kent County Employees Retirement Plan and Trust B-7

Comments, Recommendation and Conclusion Recommendation for Reserve Transfers: In accordance with (i) the established practice concerning the distribution of year end Income-Expense Reserve balances as provided in Section 9.05, and (ii) the Section 9.04(b) requirement that the year end balance in the Reserve for Retired Benefit Payments be set equal to the present value of pensions being paid, we recommend the following reserve transfers as of January 1, 2016. Any undistributed Income-Expense Reserve balance should be transferred to the Reserve for County Contributions and the January 1, 2016 Reserve for Retired Benefit Payments balance should be set equal to $415,851,853 by transfer of any shortfall or surplus from/to the Reserve for County Contributions. These transfers were assumed to have been made for purposes of computing the employer contribution rates on page B-1. Conclusion: The County's contribution rate for the fiscal year beginning January 1, 2017 has been computed to be 9.57% of active member payroll. It is the actuary s opinion that the required contribution rates determined by the most recent actuarial valuation are sufficient to meet the Plan s financial objective, presuming continued timely receipt of required contributions. Kent County Employees Retirement Plan and Trust B-8

OTHER OBSERVATIONS General Implications of Contribution Allocation Procedure or Funding Policy on Future Expected Contributions and Funded Status Given the Plan s contribution allocation procedure, if all actuarial assumptions are met (including the assumption of the Retirement Plan earning 7.00% on the Market Value of Assets), it is expected that: 1. The employer normal cost is sufficient to cover the cost of benefits accruing each year; 2. The Unfunded Actuarial Accrued Liabilities (UAAL) will continue to be fully amortized; and 3. The funded status of the Retirement Plan will continue to increase gradually towards a 100% funded ratio. Limitations of Funded Status Measurements Unless otherwise indicated, a funded status measurement presented in this report is based upon the Actuarial Accrued Liability (AAL) and the Funding Value of Assets (FVA). Unless otherwise indicated, with regard to any funded status measurements presented in this report: 1. The measurement is inappropriate for assessing the sufficiency of Retirement Plan assets to cover the estimated cost of settling the Retirement Plan s benefit obligations, for example: transferring the liability to an unrelated third party in a market value type transaction. 2. The measurement is dependent upon the Actuarial Cost Method which, in combination with the Retirement Plan s amortization policy, affects the timing and amounts of future contributions. The amounts of future contributions will most certainly differ from those assumed in this report due to future actual experience differing from assumed experience based upon the actuarial assumptions. A funded status measurement in this report of 100% is not synonymous with no required future contributions. Even if the funded status is over 100%, the Pension Plan would still require future normal cost contributions (i.e., contributions to cover the cost of active membership accruing an additional year of service credit). 3. The measurement would produce a different result if the Market Value of Assets (MVA) were used instead of the FVA, unless the MVA is used in the measurement. Kent County Employees Retirement Plan and Trust B-9

OTHER OBSERVATIONS Limitations of Project Scope Actuarial standards do not require the actuary to evaluate the ability of the plan sponsor or other contributing entities to make required contributions to the plan when due. Such an evaluation was not within the scope of this project and is not within the actuary s domain of expertise. Consequently, the actuary performed no such evaluation.

Valuation Assets as a percent of AAL is a traditional measure of a Plan's funding progress. Except in years when the Plan is amended or actuarial assumptions are revised, this percent can be expected to increase gradually toward 100%. UAAL as a percent of Valuation Payroll is another relative index of condition. Unfunded actuarial accrued liabilities represent debt, while active member payroll represents the Plan's capacity to collect contributions to pay toward debt. The lower the percent, the greater the financial strength and vice-versa. Kent County Employees Retirement Plan and Trust B-12

The Funding Value of Assets recognizes assumed investment income (line E2) fully each year. Differences between actual and assumed investment income (line E3) are phased-in over a closed 4-year period. During periods when investment performance exceeds the assumed rate, Funding Value of Assets will tend to be less than market value. During periods when investment performance is less than the assumed rate, Funding Value of Assets will tend to be greater than market value. The Funding Value of Assets is unbiased with respect to Market Value. At any time it may be either greater or less than Market Value. If actual and assumed rates of investment income are exactly equal for 3 consecutive years, the Funding Value will become equal to Market Value. Kent County Employees Retirement Plan and Trust C-13

Actuarial Valuation Method Normal cost and the allocation of benefit values between service rendered before and after the valuation date was determined using an individual entry-age normal cost method having the following characteristics: (i) (ii) the annual normal costs for each individual active member, payable from the date of employment to the date of retirement, are sufficient to accumulate the value of the member's benefit at the time of retirement; each annual normal cost is a constant percentage of the member's year-byyear projected covered pay. Financing of Unfunded Actuarial Accrued Liabilities. Unfunded actuarial accrued liabilities were amortized by level (principal & interest combined) percent-of-payroll contributions over a closed period of 23 years. Kent County Employees Retirement Plan and Trust D-1

Assumptions Used in the Valuation The actuarial assumptions are adopted by the Retirement Board after consultation with the actuary. In general, the actuarial assumptions were based on plan experience, as well as on experience of other plans in Michigan. In addition, the mortality tables also reflect national trends. The reasonableness of the economic assumptions was based upon capital market expectations provided by various investment consultants and other sources such as the Social Security Trustees report. The actuarial assumptions represent estimates of future experience. The actuary calculates the contribution requirements and benefit values by applying assumptions to the benefit provisions and participant information furnished, using the valuation methods described on the previous page. The principal areas of financial risk which require assumptions about future experiences are: long term rates of investment return to be generated by the assets of the Plan, patterns of pay increases to members, rates of mortality among members, retirees and beneficiaries, rates of withdrawal from active memberships, rates of disability among members, and the age patterns of service retirements. In a valuation, the actuary calculates the monetary effect of each assumption for as long as a present covered person survives - - - a period of time which can be as long as a century. Actual experience of the Plan will not coincide exactly with assumed experience, regardless of the wisdom of the assumptions, or the skill of the actuary and the precision of the many calculations made. Each valuation provides a complete recalculation of assumed future experience and takes into account all past differences between assumed and actual experience. The result is a continual series of adjustments (usually small) to the computed contribution rate. From time to time it becomes appropriate to modify one or more of the assumptions, to reflect experience trends (but not random year-to-year fluctuations). Assumptions were last revised for the December 31, 2015 actuarial valuation. Kent County Employees Retirement Plan and Trust D-2

The rate of investment return was 7.0% per year compounded yearly. This assumption is used to make money payable at one point in time equal in value to a different amount of money payable at another point in time. The assumed real return for funding purposes is the rate of return in excess of average salary increases. Considering other current assumptions used in the valuation, the 7.0% translates to a real return of approximately 3.0%. Experience over the last 5 years is illustrated below: Year Ending December 31 2015 2014 2013 2012 2011 5-Year Average 1) Nominal rate (net) 8.7% 9.8% 9.7% 7.0% 5.5% 8.1% 2) Increase in CPI 0.7 0.8 1.5 1.7 3.0 1.5 3) Average salary increase # 7.9 2.7 2.9 3.4 3.7 4.1 4) Real return as measured - CPI 6.6 - Average salary increase 4.0 - Assumption 3.0 # Excludes new hires and terminations during year. The nominal rate of return was computed using the approximate formula: i = I divided by 1/2 (A+B-I), where I is the net realized investment income, A is the beginning of year asset value and B is the end of year asset value. The rates of salary increase used for individual members are in accordance with the following table. This assumption is used to project a member's current salary to the salaries upon which benefit amounts will be based. Sample Ages Salary Increase Assumptions For an Individual Member Base (Economic) Merit & Seniority Increase Next Year 20 7.0 % 4.0 % 11.0 % 25 5.8 4.0 9.8 30 3.5 4.0 7.5 35 2.1 4.0 6.1 40 1.4 4.0 5.4 45 1.1 4.0 5.1 50 0.8 4.0 4.8 55 0.5 4.0 4.5 60 0.2 4.0 4.2 65 0.0 4.0 4.0 If the number of active members remains constant, then the total active member payroll will increase 4.0% annually, the base portion of the individual salary increase assumptions. This increasing payroll was recognized in amortizing unfunded accrued liabilities. These rates were first used for the December 31, 2013 valuation. Kent County Employees Retirement Plan and Trust D-3

The mortality table was the RP-2014 Mortality Tables with 2-dimensional, fully generational improvements projected with the MP-2015 Mortality Improvement Scales. These tables were first used for the December 31, 2015 valuation. (These tables were used for valuation purposes only. For optional form of payment actuarial equivalent benefit computations, a unisex mortality table based on the 1983 Group Annuity Mortality Table made up of 60% male and 40% female rates, is used.)
