January 26, 2016 Tony Saunders Wayne County 500 Griswold, 20th Floor Detroit, MI 48226 This report summarizes the GASB actuarial valuation for Wayne County 2014/15 fiscal year. To the best of our knowledge, the report presents a fair position of the funded status of the plan in accordance with GASB Statement No. 45 (Accounting and Financial Reporting by Employers for Post-Employment Benefits Other Than Pensions). The valuation is also based upon our understanding of the plan provisions as summarized within the report. The information presented herein is based on the actuarial assumptions and substantive plan provisions summarized in this report and participant information furnished to us by the Plan Sponsor. We have reviewed the employee census provided by the Plan Sponsor for reasonableness when compared to the prior information provided but have not audited the information at the source, and therefore do not accept responsibility for the accuracy or the completeness of the data on which the information is based. When relevant data may be missing, we may have made assumptions we feel are neutral or conservative to the purpose of the measurement. We are not aware of any significant issues with and have relied on the data provided. The discount rate and other economic assumptions have been selected by the Plan Sponsor. Demographic assumptions have been selected by the Plan Sponsor with the concurrence of Nyhart. In our opinion, the actuarial assumptions are individually reasonable and in combination represent our estimate of anticipated experience of the Plan. All calculations have been made in accordance with generally accepted actuarial principles and practice. 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 (such as the end of an amortization period); and

changes in plan provisions or applicable law. We did not perform an analysis of the potential range of future measurements due to the limited scope of our engagement. To our knowledge, there have been no significant events prior to the current year's measurement date or as of the date of this report that could materially affect the results contained herein.

Neither Nyhart nor any of its employees has any relationship with the plan or its sponsor that could impair or appear to impair the objectivity of this report. Our professional work is in full compliance with the American Academy of Actuaries Code of Professional Conduct Precept 7 regarding conflict of interest.

Wayne County GASB 45 Valuation Actuarys Notes For Fiscal Year Ending September 30, 2015

3 | P a g e

The prior years GASB results shown in this report are different from the Countys audited financial statement disclosure for FYE September 30, 2014 due to the October 1, 2013 Trust balance revision. There are changes to the substantive plan provisions since the last full valuation, which was for the fiscal year ending September 30, 2014. All of the changes described below decrease the Countys liabilities.

1. Retirees classified as MIRROR by the County are eligible to retain their current retiree health benefits, however, they are required to enroll in the HDHP 80/20 plan. The required retiree contribution is 10% of monthly premium. When the retiree turns 60, retiree contribution will be frozen at the applicable 10% of HDHP premium in that year until all covered members in the policy turns 65, at which time retiree health benefits come non-contributory. This change is also applicable to Mental Health Authority (MHA) retirees.

2. For all other retirees classified as non-MIRROR by the County, the Countys only obligation to these retirees is in providing stipend benefits as described

in the Substantive Plan Provisions section. These retirees must obtain their health coverage elsewhere. This change is also applicable to Mental Health Authority (MHA) retirees.

3. Non-POAM non-RMSA active employees who have at least 20 years of service as of October 1, 2015 are eligible for the stipend benefits. The Countys

only obligation to these employees at retirement is in providing stipend benefits as described in the Substantive Plan Provisions section. These employees must obtain their health coverage elsewhere at retirement.

4. For POAM employees who are non-RMSA eligible:

a. Those who retire prior to October 1, 2017 are eligible to retain their current health benefits, however, they are required to enroll in the HDHP 80/20 plan. The required contribution at retirement is 10% of monthly premium. When the retiree turns 60, retiree contribution will be frozen at the applicable 10% of HDHP premium in that year until all covered members in the policy turns 65, at which time retiree health benefits come non-contributory.

b. Those who do not retire by October 1, 2017 are eligible to receive stipend benefits if they have at least 20 years of service as of October 1, 2017. The Countys only obligation to these employees at retirement is in providing stipend benefits as described in the Substantive Plan Provisions section. These employees must obtain their health coverage elsewhere at retirement.

5. RMSA active employees are not eligible to enroll in the Countys group health plan at retirement.


4 | P a g e

Two actuarial assumptions have been updated since the last full valuation, which was for the fiscal year ending September 30, 2014:

1. Amortization type for Countys liabilities has been changed to a closed period from an open period (the remaining amortization period as of September 30, 2015 is 30 years). A closed period amortization is a more conservative and prudent approach to take for pre-funding long-term obligations, such as OPEB liabilities. This change has no impact in this years Countys liabilities or Annual Required Contribution.

2. Health care trend rates have been reset to the same initial trend used in the last valuation. Comparison of actual and expected trend rates are as shown

below. This change caused an increase in the Countys liabilities.

Annual Required Contribution (ARC) is the annual expense recorded in the income statement under GASB 45 accrual accounting. It replaces the cash basis method of accounting recognition with an accrual method. The GASB 45 ARC is higher than the pay-as-you-go cost because it includes recognition of employer costs expected to be paid in future accounting periods.

Pay-as-you-go Cost is the expected total employer cash cost for the coming period based on all explicit and implicit subsidies. It is also the amount recognized as expense on the Income Statement under pay-as-you-go accounting.

Net OPEB Obligation is the cumulative difference between the annual OPEB cost and employer contributions. This obligation will be created if cash contributions are less than the current year expense under GASB 45 accrual rules. The net obligation is recorded as a liability on the employers balance sheet which will reduce the net fund balance. The value of implicit subsidies is considered as part of cash contributions for the current period. Other cash expenditures that meet certain conditions are also considered as contributions for GASB 45 purposes.

Wayne County GASB 45 Valuation Reconciliation of Actuarial Accrued Liability For Fiscal Year Ending September 30, 2015

11 | P a g e

The Actuarial Accrued Liability (AAL) is expected to change on an annual basis as a result of expected and unexpected events. Under normal circumstances, it is generally expected to have a net increase each year. Below is a list of the most common events affecting the AAL and whether they increase or decrease the liability. Expected Events

Increases in AAL due to additional benefit accruals as employees continue to earn service each year

Increases in AAL due to interest as the employees and retirees age

Decreases in AAL due to benefit payments Unexpected Events

Increases in AAL when actual premium rates increase more than expected. A liability decrease occurs when premium rates increase less than expected.

Increases in AAL when more new retirements occur than expected or fewer terminations occur than anticipated. Liability decreases occur when the opposite outcomes happen.

Increases or decreases in AAL depending on whether benefit provisions are improved or reduced.

Reconciliation of AAL shows what the actuary expects the actuarial accrued liability to be at the beginning of the following fiscal year based on current assumptions and plan provisions. The expected end of year AAL will change as actual plan experience varies from assumptions. Generally, the AAL is expected to have a net increase each year.

Wayne County GASB 45 Valuation Substantive Plan Provisions For Fiscal Year Ending September 30, 2015

14 | P a g e

Retiree Health Benefits Non-POAM employees who have at least 20 years of service as of October 1, 2015 are eligible for stipend benefits once they meet the eligibility requirements noted in the next page.

POAM employees who retire prior to October 1, 2017 by meeting the eligibility requirements noted in the next

page are eligible to retain their current retiree health benefits but they are required to enroll in the HDHP 80/20 plan and pay the required contributions as described on page 17. POAM employees who retire on/after October 1, 2017 are eligible for stipend benefits if they have at least 20 years of service as of October 1, 2017.

Existing retirees classified as MIRROR by the County are eligible for stipend benefits. Existing retirees classified

as non-MIRROR by the County are eligible to retain their current retiree health benefits but they are required to enroll in the HDHP 80/20 plan and pay the required contributions as describe on page 17.

Stipend Benefits Employees and existing retirees eligible for stipend benefits are required to seek health coverage elsewhere and

the Countys only obligation to this group is in providing the stipend benefits as noted below. Prior to Medicare eligibility, the monthly stipend benefits provided by the County are as shown in the table

below.

Retiree only Retiree + Spouse (or 1

Dependent) Family

AGI* Stipend AGI* Stipend AGI* Stipend

< $30k $ 100 < $35k $ 150 < $40k $ 150

$30 to $45k $ 200 $35 to $65k $ 300 $40 to $55k $ 300

>= $45k $ 400 >= $65k $ 750 $55 to $70k $ 400

>= $70k $ 800

Upon Medicare eligibility, the monthly stipend is $130 per person, increasing annually based on percentage

increase in general wage levels for non-supervisory AFSCME for the annual period being calculated, but not more than 2%. If there is negative % change from 1/1/2015 in general wage levels for non-supervisory AFSCME, stipend may decrease but not less than $0. The maximum stipend shall never exceed 12.5% of the starting stipend (or $146.25). Additionally, there is a $5 monthly stipend that will replace the existing $29.50 Medicare Part B reimbursement. The additional $5 monthly stipend is not expected to increase in the future.

* AGI is short for Adjusted Gross Income. For existing retirees, their AGI is based on their pension benefit. For

future retirees, they are assumed to receive the maximum stipends shown above.

Spouse Benefit Surviving spouse can continue coverage after the death of the retiree or active employees eligible to retire.

County subsidy and/or stipend benefit continues to surviving spouse upon death of the retiree or active employee eligible to retire.

Life Insurance The County pays for life insurance benefits at retirement. Majority of current retirees have $5,000 life insurance

benefits, but there are others who have varying life insurance benefit amounts. Liability for retirees life insurance benefits paid by Prudential is not included in this report.

For future retirees who are eligible for stipend benefits, theres no subsidized life insurance benefits. For those

who are allowed to retain the subsidized retiree health benefits, they are eligible to receive $5,000 life insurance benefits at retirement.

Retiree Cost Sharing All retirees receiving subsidized retiree health benefits are required to enroll in the HDHP 80/20 plan and contribute 10% of the monthly premium. When the retiree turns 60, retiree contribution will be frozen at the applicable 10% monthly premium in that year until all covered members in the policy turn 65, at which time retiree health benefits become non-contributory.

Medical Benefit All retirees receiving subsidized retiree health benefits are required to enroll in the BCBS HDHP 80/20 plan. All

BCBS benefit options are self-insured. The monthly premiums on October 1, 2015 for the BCBS HDHP 80/20 plan are as shown below.

Wayne County GASB 45 Valuation Actuarial Methods and Assumptions For Fiscal Year Ending September 30, 2015

19 | P a g e

The actuarial assumptions used in this report represent a reasonable long-term expectation of future OPEB outcomes. As national economic and County experience change over time, the assumptions will be tested for ongoing reasonableness and, if necessary, updated. There are changes to substantive plan provisions and actuarial methods and assumptions since the last GASB valuation, which was for the fiscal year ending September 30, 2014. Refer to the Actuarys Notes section for complete information on these changes. For the current year GASB valuation, we have updated the per capita costs. We expect to update health care trend rates and per capita costs again in the next full GASB valuation, which will be for the fiscal year ending September 30, 2017. Measurement Date September 30, 2015 with results actuarially rolled-back to October 1, 2014 on a no loss/no gain basis. Discount Rate 4.0% partially funded Payroll Growth 3.0% per year (used for amortization purposes only) Inflation Rate 3.0% per year Cost Method Projected Unit Credit with linear proration to decrement Amortization County: Level % of pay over a 30-year closed period MHA: Level dollar over a 15-year closed period Census Data Census information was provided by the County as of September 2015. We have reviewed it for reasonableness

and no material modifications were made to the census data except for the following:

Employees who were noted in the prior valuations census data as ineligible for retiree health benefits due to employment category are assumed to stay ineligible in this years valuation.

Employer Funding Policy Certain funds within the County will make an additional pre-funding contribution at the Countys discretion into

a Section 115 Trust that is equal to the difference between the Annual Required Contribution (ARC) allocated to that fund and the pay-go costs. Allocation of the total ARC to each fund is currently done in the same proportion as their share of retiree healthcare expenses. The Section 115 Trust is currently invested in a Master Demand Account, which is a liquid account with a very low rate of return. The County has elected not to increase the discount rate to reflect the partial pre-funding for these specific funds until they can draw up a Trust policy that contains the recommended asset investment mix that is more aggressive than their current investment.

10 POAM employees who are eligible to retire prior to October 1, 2017 are assumed to retire when they are first eligible.

The initial trend rate was based on a combination of employer history, national trend surveys, and professional judgment. The ultimate trend rate was selected based on historical medical CPI information.

Retiree Contributions Retiree contributions are assumed to increase 5% annually. Per Capita Costs Annual per capita costs were calculated based on the 2015/16 premium rates actuarially increased using health

index factors and current enrollment. The costs are assumed to increase with health care trend rates. Annual per capita costs by plan are as shown below:

< 55 $ 4,400

55 59 $ 5,400

60 64 $ 6,600

65 69 $ 3,500

70 74 $ 4,200

75 79 $ 4,800

80+ $ 5,600

Health Care Coverage Election Rate 100% of active employees eligible for subsidized retiree health benefits with current coverage are assumed to

continue coverage at retirement. 0% of active employees eligible for subsidized retiree health benefits without current coverage are assumed to

elect coverage at retirement. 100% of active employees eligible stipend benefits are assumed to receive stipend benefits at retirement. 100% of retirees with current coverage are assumed to continue coverage. 0% of retirees without current coverage are assumed to elect coverage in the future. Spousal Coverage Spousal coverage for current retirees is based on actual data. 70% of employees are assumed to be married at retirement. Husbands are assumed to be three years older than

wives.

The per capita costs represent the cost of coverage for a retiree-only population. Actuarial standards require the recognition of higher inherent costs for a retired population versus an active population.

Illustration of GASB Calculations The purpose of the illustration is to familiarize non-actuaries with the GASB 45 actuarial calculation process. I. Facts

1. The employer provides subsidized retiree health coverage worth $100,000 to employees retiring at age 55 with 25 years of service. The employer funds for retiree health coverage on a pay-as-you-go basis.

2. Employee X is age 50 and has worked 20 years with the employer.

3. Retiree health subsidies are paid from the general fund assets which are expected to earn 4.5% per year on a long-term basis.

4. Based on Employee Xs age and sex he has a 98.0% probability of living to age 55 and a 95.0% probability of continuing to work to age 55.

II. Calculation of Present Value of Future Benefits Present Value of Future Benefits represents the cost to finance benefits payable in the future to current and future retirees and beneficiaries, discounted to reflect the expected effects of the time value (present value) of money and the probabilities of payment.

Value Description

A. $100,000 Projected benefit at retirement

B. 80.2% Interest discount for five years = (1 / 1.045)5

C. 98.0% Probability of living to retirement age

D. 95.0% Probability of continuing to work to retirement age

E. $74,666 Present value of projected retirement benefit measured at employees current age = A x B x C x D


33 | P a g e

Illustration of GASB Calculations (continued) III. Calculation of Actuarial Accrued Liability Actuarial Accrued Liability represents the portion of the Present Value of Future Benefits which has been accrued recognizing the employees past service with the employer. The Actuarial Accrued Liability is a required disclosure in the Required Supplementary Information section of the employers financial statement.

Value Description

A. $74,666 Present value of projected retirement benefit measured at employees current age

B. 20 Current years of service with employer

C. 25 Projected years of service with employer at retirement

D. $59,733 Actuarial accrued liability measured at employees current age = A x B / C

IV. Calculation of Normal Cost Normal Cost represents the portion of the Present Value of Future Benefits allocated to the current year.

Value Description

A. $74,666 Present value of projected retirement benefit measured at employees current age

B. 25 Projected years of service with employer at retirement

C. $2,987 Normal cost measured at employees current age = A / B

V. Calculation of Annual Required Contribution Annual Required Contribution is the total expense for the current year to be shown in the employers income statement.

Value Description

A. $2,987 Normal Cost for the current year

B. $3,509 30-year amortization (level dollar method) of Unfunded Actuarial Accrued Liability using a 4.5% interest rate discount factor

C. $292 Interest adjustment = 4.5% x (A + B)

D. $6,788 Annual Required Contribution = A + B + C

Definitions GASB 45 defines several unique terms not commonly employed in the funding of pension and retiree health plans. The definitions of the terms used in the GASB actuarial valuations are noted below. 1. Actuarial Accrued Liability That portion, as determined by a particular Actuarial Cost Method, of the Actuarial Present Value of plan benefits and expenses

which is not provided for by the future Normal Costs.

2. Actuarial Assumptions Assumptions as to the occurrence of future events affecting health care costs, such as: mortality, withdrawal, disablement and retirement; changes in compensation and Government provided health care benefits; rates of investment earnings and asset appreciation or depreciation; procedures used to determine the Actuarial Value of Assets; characteristics of future entrants for Open Group Actuarial Cost Methods; and other relevant items.

3. Actuarial Cost Method A procedure for determining the Actuarial Present Value of future benefits and expenses and for developing an actuarially equivalent allocation of such value to time periods, usually in the form of a Normal Cost and an Actuarial Accrued Liability.

4. Actuarial Present Value The value of an amount or series of amounts payable or receivable at various times, determined as of a given date by the application of a particular set of Actuarial Assumptions. For purposes of this standard, each such amount or series of amounts is:

a) adjusted for the probable financial effect of certain intervening events (such as changes in compensation levels, Social Security, marital status, etc.); b) multiplied by the probability of the occurrence of an event (such as survival, death, disability, termination of employment, etc.) on which the payment is

conditioned; and c) discounted according to an assumed rate (or rates) of return to reflect the time value of money.

5. Annual OPEB Cost An accrual-basis measure of the periodic cost of an employers participation in a defined benefit OPEB plan.

6. Annual Required Contribution (ARC) The employers periodic required contributions to a defined benefit OPEB plan, calculated in accordance with the parameters.

7. Explicit Subsidy The difference between (a) the amounts required to be contributed by the retirees based on the premium rates and (b) actual cash contribution made by the employer.

8. Funded Ratio The actuarial value of assets expressed as a percentage of the actuarial accrued liability.

9. Healthcare Cost Trend Rate The rate of change in the per capita health claims costs over time as a result of factors such as medical inflation, utilization of healthcare services, plan design, and technological developments.


35 | P a g e

Definitions (continued) 10. Implicit Subsidy In an experience-rated healthcare plan that includes both active employees and retirees with blended premium rates for all plan

members, the difference between (a) the age-adjusted premiums approximating claim costs for retirees in the group (which, because of the effect of age on claim costs, generally will be higher than the blended premium rates for all group members) and (b) the amounts required to be contributed by the retirees.

11. Net OPEB Obligation The cumulative difference since the effective date of this Statement between annual OPEB cost and the employers contributions to the plan, including the OPEB liability (asset) at transition, if any, and excluding (a) short-term differences and (b) unpaid contributions that have been converted to OPEB-related debt.

12. Normal Cost The portion of the Actuarial Present Value of plan benefits and expenses which is allocated to a valuation year by the Actuarial Cost Method.

13. Pay-as-you-go A method of financing a benefit plan under which the contributions to the plan are generally made at about the same time and in about the same amount as benefit payments and expenses becoming due.

14. Per Capita Costs The current cost of providing postretirement health care benefits for one year at each age from the youngest age to the oldest age at which plan participants are expected to receive benefits under the plan.

15. Present Value of Future Benefits Total projected benefits include all benefits estimated to be payable to plan members (retirees and beneficiaries, terminated employees entitled to benefits but not yet receiving them, and current active members) as a result of their service through the valuation date and their expected future service. The actuarial present value of total projected benefits as of the valuation date is the present value of the cost to finance benefits payable in the future, discounted to reflect the expected effects of the time value (present value) of money and the probabilities of payment. Expressed another way, it is the amount that would have to be invested on the valuation date so that the amount invested plus investment earnings will provide sufficient assets to pay total projected benefits when due.

16. Select and Ultimate Rates Actuarial assumptions that contemplate different rates for successive years. Instead of a single assumed rate with respect to, for example, the investment return assumption, the actuary may apply different rates for the early years of a projection and a single rate for all subsequent years. For example, if an actuary applies an assumed investment return of 8% for year 20W0, then 7.5% for 20W1, and 7% for 20W2 and thereafter, then 8% and 7.5% select rates, and 7% is the ultimate rate.

17. Substantive Plan The terms of an OPEB plan as understood by the employer(s) and plan members.
