CC - Item 8H - Post Retirement Healthcare FundingI a :Lei A TO: THE HONORABLE MAYOR AND CITY COUNCIL FROM: JEFF ALLRED, CITY MANAGER DATE: DECEMBER 13, 2011 SUBJECT: POST RETIREMENT HEALTHCARE FUNDING SUMMARY The Government Accounting Standards Board (GASB) issued GASB Statement 45 in June 2004 which requires all government agencies to evaluate and adopt a funding plan for Other Post Employment Benefits (OPEB). In fiscal year 2008 -09 the City Council approved Rosemead's funding plan which included annual payments to fund the normal cost and the amortization of the unfunded actuarial accrued liability over a five year period. These payments began in 2009 and the current fiscal year's payment will be the third. In continuing with the City's compliance under GASB 45, the City is required to perform a new valuation every two years to re- evaluate funding levels. In January 2011 PARS along with Nicolay Consulting began the development of the updated actuarial valuation. This valuation took most of the year to complete as the final figures relied on fiscal year -end financial figures as of June 30, 2011, and the report was just recently received by the City. No additional action is required by the City Council other than to receive and file the report. Staff Recommendation Staff recommends that the City Council receive and file the report. ANALYSIS The City received its first valuation report in May, 2009. In this valuation, the actuarial accrued liability was estimated at $2,660,557 with a first year normal cost of $33,482.. On May 26, 2009, the City Council voted to approve a five year funding plan for the actuarial accrued liability with payment amounts of $644,548 each year. These payments along with the annual normal cost payments were intended to reduce the actuarial accrued liability to zero which would reduce the City's future liability to only that of the normal cost. Under GASB 45, a new valuation is required every two years to re- evaluate the City's funding position in regards to other post - employment benefits (OPEB), which in Rosemead's case is retiree medical. This valuation is done according to regular retirement assumptions which include such factors as estimated retirement age, trends in healthcare costs and mortality. Furthermore, since the City "closed" it's primary OPEB plan to new employees on July 1, 2007, the amortization period for actuarial accrued liability must be set at 30 years for the first valuation and must be reduced annually. This is a key point because plans that are still open to new employees are allowed a rolling 30 year amortization period which allows for cities to spread out their future costs over a longer period of time. The easiest way to think of this is to A ., .. APPROVED FOR CITY COUNCIL AGENDA: City Council Meeting December 13, 2011 Pape 2 of 2 equate it to a mortgage. Rather than being able to finance the cost over a 30 -year mortgage, the city of a closed program may only finance it over the number of years left in the program under 30. For Rosemead this translates to a 27 year amortization period. Just as with a mortgage, the fewer the years to finance the liability, the greater the annual cost will be to the city. The valuation recently completed and scheduled to be used in the preparation of the 2011 -12 fiscal year annual reports reflects an increase in actuarial accrued liability. This liability is estimated at $3,378,875, which is an increase of $718,318 over the previous valuation. There are two driving factors which have resulted in this increase. The first factor is the continued weakening of the economy in general. The initial valuation assumed a long -term interest rate of 7.5% and with the current valuation the interest rate has been reduced to 6.0% This 1.5% decrease over a 27 year period has a significant impact on the liability amount as it requires the City to provide more funding upfront as less interest will be earned down the road. A second key component is the minimum required member contribution as required by CalPERS. Although the City's OPEB plan is "closed" to new employees, CalPERS mandates a minimum required annual contribution for all retirees, which for 2011 is $108 per month and will increase to $112 per month for 2012. The original valuation did not take this payment into account as it was understood at the time that these future amounts were not required to be included as part of the valuation. The practice of not including this has since been modified by additional GASB direction which requires agencies to include even those fixed amounts outside of the City's control. This future cost of $112 per month, which increases annually by the CPI, for every person who retires from the City creates an additional cost for not only the actuarial accrued liability, but also to the normal cost that must be paid on an ongoing basis.

CALIFORNIA 94105 -2854 TEL: 415 512-5300 FAX: 415 512 -5314 Re: Actuarial Valuation of Postemployment Medical Program The Nicolay Consulting Group is pleased to present the results of the January 1, 2011 actuarial valuation of the City of Rosemead postemployment medical program. In preparing this report, we relied on employee data and plan information provided by the City. On the basis of that information, this report has been prepared in accordance with generally accepted actuarial principles and methods. It is our opinion that the actuarial assumptions used are reasonably related to the actual experience of the plan and to anticipated future experience. The financial projections presented in this report are intended for the City's internal use in evaluating the potential cost of the retiree medical program. Because future events frequently do not occur as expected, it should be recognized that there are usually differences between anticipated and actual results. These differences may be material, especially if there are significant changes in the employee or retiree population. Consequently, we can express no assurance that the projected values will occur. We recommend that the City obtain an updated actuarial valuation on a periodic basis. Questions about the report should be directed to Doug Tokerud at (800) 998 -7675 x220.

This report provides an estimate of the City's obligation as of January 1, 2011, the effect of the GASB 45 accounting rule and a ten -year projection of the pay -as- you -go cost of providing the benefits. Section II contains valuation results. Section III describes the plans and presents a demographic summary. Section IV lists the actuarial assumptions used to complete the valuation. Section V contains a Glossary of several of the terms used in this report. Accounting Requirements In July 2004 the Governmental Accounting Standards Board issued Statement 45, Accounting and Financial Reporting by Employers for Postemployment Benefits Other Than Pensions. This statement requires governmental entities to account for postemployment benefits on an accrual basis. We understand that the City adopted GASB 45 during its 2008/09 fiscal year and elected to amortize its Unfunded Actuarial Accrued Liability (UAAL) over a closed 30 -year period. Currently the City funds its retiree healthcare benefits into an irrevocable trust. City of Rosemead Actuarial Valuation Date: January 1, 2011 Page 1 SECTION II GASB 45 requires employers to recognize postemployment healthcare expense systematically over periods approximating employees' years of service. The Actuarial Accrued Liability represents the estimated present value of future benefits that are associated with past service rendered by employees and retirees. The UAAL is the excess of the Actuarial Accrued Liability (AAL) over the Actuarial Value of Assets. Table 2 -1 contains estimates of the present value of the cost of postemployment medical benefits attributable to current retirees and employees who are expected to receive the benefit. The estimates are based on the Entry Age Normal actuarial cost method. The estimates are based on a 6.0% discount rate. Table 2 -1 also includes the City's 2011/12 Annual Required Contribution. The ARC consists of the Normal Cost plus the current year amortization of the UAAL. The amortization method used in this valuation is the level percentage of projected payroll method. The UAAL amortization will occur over a closed 30 -year period that commenced in the 2008 109 fiscal year. We assumed that 3 years of amortization have occurred and 27 years remain.

City employees are eligible for postretirement medical benefits upon reaching age 50 with a minimum of 5 consecutive years of service with the City. The City will contribute the full medical premium each month, but not more than the 'bap', as described below. For employees hired after July 1, 2007, the monthly cap is the CalPERS minimum employer contribution ($108 per month in 2011, increasing to $112 in 2012). For employees hired prior to July 2, 2007, the monthly cap is the larger of the CalPERS minimum employer contribution, or the following amount, based on years of service at retirement: Less than 12 years of service: $ 0 12 -19 years of service $ 500 At least 20 years of service $ 1,000 The City does not intend to increase these caps in the future. Medical Plans Retirees may enroll in any of the available CalPERS- sponsored medical plans. Duration of Benefits City provided benefits continue for the life of the retiree and surviving spouse.

We used the same actuarial assumptions that were used in the most recent California PERS pension valuations. Actuarial Cost Method The valuation was completed using the Entry Age Normal Cost Method. An Actuarial Cost Method is a procedure for allocating the actuarial present value of 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. The Entry Age Normal cost method allocates the present value of future benefits on a level basis over the earnings or service (in this case earnings) of each employee between the hire date and assumed retirement age. The portion of the present value of future benefits allocated to a valuation year is called the Normal Cost. The portion allocated to all prior years is called the Actuarial Accrued Liability. Valuation Date The valuation date is January 1, 2011. This date is the starting point from which current health premium costs are increased according to the assumed annual rates of health care cost trend. The City's census is projected from the valuation date to the date of the final benefit payment for each employee and retiree on the census. After calculating future costs for the projected retiree and dependent population, all liabilities are discounted back to the valuation date to obtain the present value of future costs. The valuation results as of January 1, 2011 were used to determine the ARC, assumed to stay constant, for the 2011 -2012, 2012 -2013 and 2013 -2014 fiscal years. Economic Assumptions Discount Rate Valuation results were computed based on a 6.00% discount rate. The City has indicated this is the expected rate of return it anticipates over the long -term on the funds that will be used to pay retiree benefits. City of Rosemead Actuarial Valuation Date: January 1, 2011 Page 7 Baseline Cost Estimates of retiree health benefit obligations are normally based on current costs for a one year period. We refer to this as the baseline cost. The components of baseline cost, such as average per capita cost, and the current plan population are projected into the future to estimate the cost of future benefits. Table 4 -1 contains the 2011 CaIPERS Los Angeles area premium rates. Contributions The retiree is responsible for any premium cost in excess of the Maximum City contribution. City of Rosemead Actuarial Valuation Date: January 1, 2011 Page 8 Table 4 -1 City of Rosemead Monthly Retiree Medical Premium Rates for January 2011 through December 2011 Retiree Only Two Party Younger than age 65 Blue Shield Access $ 496.93 $ 993.86 Blue Shield NetValue $ 427.58 $ 855.16 Kaiser $ 434.00 $ 868.00 PERS Choice $ 496.15 $ 992.30 PERS Select $ 433.87 $ 867.74 PERS Care $ 787.24 $1,574.48 Age 65 and older Blue Shield Access $ 337.88 $ 675.76 Blue Shield NetValue $ 337.88 $ 675.76 Kaiser $ 282.30 $ 564.60 PERS Choice $ 375.88 $ 751.76 PERS Select $ 375.88 $ 751.76 PERS Care $ 433.66 $ 867.32 Contributions The retiree is responsible for any premium cost in excess of the Maximum City contribution. City of Rosemead Actuarial Valuation Date: January 1, 2011 Page 8 Health Care Trend The rate of increase in per capita health care costs is commonly referred to as the health care trend rate. Based on our experience with postemployment health plans, we selected the following annual premium trend rates for use in this valuation: Table 4 -2 Annual Premium Trend Rate Assumption the Calendar Year Estimated Beginning Increase January 1, 2012 7.6% January 1, 2013 7.2% January 1, 2014 6.8 % January 1, 2015 6.4% January 1, 2016 6.0% January 1, 2017 5.6 % January 1, 2018 5.3 % January 1, 2019 and thereafter 5.0% Administrative Expenses We assumed that there are no administrative fees other than those included in the premium rates. Payroll Increases In this valuation we assumed a 3.25% annual rate of increase in payroll. This rate is a component of the Entry Age Normal Actuarial Cost Method. Amortization Methodology GASB 45 allows amortization of the Unfunded Actuarial Accrued Liability based on a level dollar approach or as a level percentage of covered payroll. The maximum amortization period is 30 years. This valuation is based on a closed 30 -year amortization of the Unfunded Actuarial Accrued Liability as a level dollar amount. Plan Assets We understand that the City has commenced a pre- funding program and plans to fund the Unfunded Actuarial Accrued Liability over the next three years. City of Rosemead Actuarial Valuation Date: January 1, 2011 Page 9 Demographic Assumptions In estimating this obligation, a number of demographic assumptions are needed. These assumptions are the same as those used in the most recent California PERS valuation. Withdrawal This valuation is based on withdrawal rates used in the most recent California PERS Public Agency Miscellaneous retirement plan valuations. Selected rates are shown below.

Health Plan Participation We assumed that 100% of future eligible retirees will enroll in one of the CalPERS medical plans. We assumed that future retirees will enroll a spouse if they currently are covering a spouse, and that female spouses are 3 years younger than male spouses. Future retirees are assumed to elect the same medical plan coverage after retirement that they have now. Employees with no current medical coverage are assumed to elect Blue Shield employee -only coverage upon retirement. Medicare Coverage We assumed that all future retirees will be eligible for Medicare when they reach age 65. City of Rosemead Actuarial Valuation Date: January 1, 2011 Page 12 • Accrual Accounting — A method of matching the cost of an employee's service, including long term obligations such as OPEB, to that employee's period of active service. • Actuarial Accrued Liability (AAL) — The Actuarial Present Value of all postemployment benefits attributable to past service. Note: the AAL is sometimes referred to as the Past Service Liability. • Actuarial Cost Method — A procedure for allocating the actuarial present value of 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. • Actuarial Present Value — The value of an amount or series of amounts payable or receivable at various times. 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, 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 • Actuarial Valuation — The determination, as of a valuation date, of the Normal Cost, Actuarial Accrued Liability, Actuarial Value of Assets and related Actuarial Present Values. Actuarial Value of Assets — The value of cash, investments and other property belonging to a plan. These are amounts that may be applied to fund the Actuarial Accrued Liability. Note: assets must be segregated and placed in a Trust in order to be considered OPEB assets • Amortization Payment — That portion of the Annual OPEB cost which is designed to pay interest on and to amortize the Unfunded Actuarial Accrued Liability. City of Rosemead Actuarial Valuation Date: January 1, 2011 Page 13 In the year that Statement 45 becomes effective an employer is allowed to commence amortization of the Unfunded Actuarial Accrued Liability, over a period not to exceed 30 years. • Annual Other Postemplovment Benefit Cost (OPEB) cost - An accrual - basis measure of the periodic cost of an employer's participation in a defined benefit OPEB plan. The annual OPEB cost is the amount that must be calculated and reported as an expense. When an employer has no net OPEB obligation (e.g., in the year of implementation) the annual OPEB cost is equal to the Annual Required Contribution (ARC). In subsequent years the Annual OPEB cost will include • the ARC (equal to the Normal Cost plus one year's amortization of the Unfunded Actuarial Accrued Liability); • one year's interest on the net OPEB obligation at the beginning of the year using the valuation discount rate; and • an adjustment to the ARC. This adjustment is intended to provide a reasonable approximation of that portion of the ARC that consists of interest associated with past contribution deficiencies. GASB Statement No. 45 specifies that this adjustment should be equal to an amortization of the discounted present value of the net OPEB obligation at the beginning of the year. The amortization should be calculated using the same amortization method and period used in determining the ARC for that year. If the net OPEB obligation is positive the adjustment should be deducted from the ARC. • Note: As long as the net OPEB obligation is zero, there will not be any interest charge or adjustment to the ARC. However, if an employer does not contribute the full amount of the ARC, a net OPEB obligation will emerge. • Annual required contributions of the employer (ARC) - The employer's periodic required contributions to a defined benefit OPEB plan, calculated in accordance with the parameters. • Defined benefit OPEB plan - An OPEB plan having terms that specify the benefits to be provided at or after separation from employment. The benefits may be specified in dollars (for example, a flat dollar payment or an amount based on one or more factors, such as age, years of service, and compensation), or as a type or level of coverage (for example, prescription drugs or a percentage of healthcare insurance premiums). City of Rosemead Actuarial Valuation Date: January 1, 2011 Page 14 • Defined contribution plan - A pension or OPEB plan having terms that (a) provide an individual account for each plan member and (b) specify how contributions to an active plan member's account are to be determined, rather than the income or other benefits the member or his beneficiaries are to receive at or after separation from employment. Those benefits will depend only on the amounts contributed to the member's account, earnings on investments of those contributions, and forfeitures of contributions made for other members that may be allocated to the member's account. For example, an employer may contribute a specified amount to each active member's postemployment healthcare account each month. At or after separation from employment, the balance of the account may be used by the member or on the member's behalf for the purchase of health insurance or other healthcare benefits. • Discount rate - the estimated long -term investment yield on the investments that are expected to be used to finance the payment of benefits. The discount rate is used to calculated the present value of future benefits. • Employer's contributions - Contributions made in relation to the annual required contributions of the employer (ARC). An employer has made a contribution in relation to the ARC if the employer has (a) made payments of benefits directly to or on behalf of a retiree or beneficiary, (b). made premium payments to an insurer, or (c) irrevocably transferred assets to a trust, or an equivalent arrangement, in which plan assets are dedicated to providing benefits to retirees and their beneficiaries in accordance with the terms of the plan and are legally protected from creditors of the employer(s) or plan administrator. • Healthcare cost trend rate - The rate of change in 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. • Investment return assumption (discount rate) - The rate used to adjust a series of future payments to reflect the time value of money. • Mortality rates — the assumed probability of dying at a specified age. In this valuation the rates are a function of age and gender. • Net OPEB obligation - The cumulative difference since the effective date of GASB Statement 45 between annual OPEB cost and the employer's 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. If an employer contributes the annual OPEB cost to the plan each year, and there are no actuarial or investment gains or losses then the net OPEB Obligation will remain zero.

Another interpretation is that the Normal Cost is the present value of future benefits that are "earned" by employees for service rendered during the current year. • OPEB assets - The amount recognized by an employer for contributions to an OPEB plan greater than OPEB expenses.. • OPEB expense - The amount recognized by an employer in each accounting period for contributions to an OPEB plan on the accrual basis of accounting. • Other postemployment benefits (OPEB) - Postemployment benefits other than pension benefits. Other postemployment benefits (OPEB) include postemployment healthcare benefits, regardless of the type of plan that provides them, and all postemployment benefits provided separately from a pension plan, except benefits defined as special termination benefits. • Plan assets - Resources, usually in the form of stocks, bonds, and other classes of investments, that have been segregated and restricted in a trust, or in an equivalent arrangement, in which (a) employer contributions to the plan are irrevocable, (b) assets are dedicated to providing benefits to retirees and their beneficiaries, and (c) assets are legally protected from creditors of the employer(s) or plan administrator, for the payment of benefits in accordance with the terms of the plan. • Present Value — See Actuarial Present Value. • Proiected Unit Credit Cost Method — An actuarial cost method under which the projected benefits of each individual included in an Actuarial Valuation are separately calculated and allocated to each year service by a consistent formula. • Retirement rates — the annual rate of retirement. In this valuation the rates are a function of retirement age and years of service at retirement. • Substantive plan - The terms of an OPEB plan as understood by the employer(s) and plan members. • Unfunded Actuarial Accrued Liability (UAAL) — The excess of the Actuarial Accrued Liability over the Actuarial Value of Assets. • Valuation date — The date as of which the postretirement benefit obligation is determined. • Withdrawal rates — the annual rate of withdrawal from service. In this valuation the rates are a function of age at hire and years of service. City of Rosemead Actuarial Valuation Date: January 1, 2011 Page 16
