2018-096 Pension Plan UpdateDate: July 27, 2018 Report No. 2018-096 Page | 1 INFORMAL STAFF REPORT TO MAYOR AND CITY COUNCIL SUBJECT: Update regarding the funded status and funding progress of the Texas Municipal Retirement System (TMRS) and the Denton Firemen’s Relief and Retirement Fund (DFRRF). EXECUTIVE SUMMARY: As part of our annual budget discussions, staff provides the City Council with information on the status of our pension plans and the most recent actuarial evaluations. This report is intended to provide a high level overview of the history and structure of each plan, investment performance, and overall funded status. The DFRRF is currently in the process of completing a new actuarial evaluation, and we expect this to be presented to Council for review in the fall of 2018. BACKGROUND: The City of Denton participates in two separate pension plans. The DFRRF covers firefighters in the Denton Fire Department. The TMRS plan covers all other City of Denton employees with the exception of temporary positions. TMRS Overview: TMRS was created in 1948 by the Texas Legislature. TMRS is a hybrid of a defined benefit and defined contribution plan. Under this approach, contributions are defined until the date of retirement. Upon retirement, the value of these contributions and investment earnings define the benefits for the retiree (also known as a cash balance plan). In this way, the unfunded liabilities associated with many defined benefit plans are minimized. While TMRS is a state-wide retirement system, the plan does not receive any state funding. Rather, all funding associated with TMRS is provided by employers, employees, and investment earnings of the system. Further, individual cities determine the level of benefits that will be provided to their retirees. As of December 31, 2017, the TMRS system had 883 cities that participate in the plan. Collectively, these cities have 167,577 employee accounts and 62,776 retirement accounts. The market value of the assets in TMRS is approximately $28.6 billion. Specific information for the City of Denton’s TMRS plan is provided in the attached excerpt from the City’s Comprehensive Annual Financial Report (CAFR). Investment Performance The TMRS plan assumes an annual investment return equal to 6.75% of plan assets. However, the actuarial valuation process utilizes asset smoothing techniques to “smooth out” the natural Date: July 27, 2018 Report No. 2018-096 Page | 2 year-to-year fluctuations that are inherent in the investment markets. Below is a history of the TMRS investment rate of returns achieved compared to the stated goal of 6.75% (shown as a red line in the below graph). Over this period, TMRS has achieved an average investment return equivalent to 7.42% (arithmetic average). Note: TMRS began measuring investment returns on a “Total Return” basis in 2008, Prior to this time, investment performance reflected yields on the bond portfolio. While TMRS has had strong investment returns in the past, there is no guarantee that the system will be able to achieve these rates in the future. However, by continuing to diversify the portfolio, TMRS investment managers believe they will be able to achieve an average 6.75% return over time. It is also important to note that any one year, or even a series of years, of below average investment returns is not a cause for alarm. The TMRS plan is designed to provide benefits for employees and retirees over decades, and as such, a long-term view of investment performance assumptions is the proper way to evaluate the health of the plan. Actuarial Information and Funding Progress: As of December 31, 2017, the City of Denton had an Actuarial Value of Assets (AVA) of $389.9 million and a Total Actuarial Accrued Liability (AAL) of $467.8 million for the TMRS plan. This equates to an Unfunded Actuarial Accrued Liability (UAAL) of $77.9 million and a funded ratio of 83.3%, compared to 81.1% in 2015 and 82.1% in 2016. The UAAL is being amortized over a period of 17 years in our existing contribution rate, so assuming all assumptions are met, the TMRS plan for Denton will be 100% funded by 2034. However, if investment returns or other economic assumptions are not realized, the fund will amortize these actuarial differences over a longer period of time, and the full funding of the plan may be extended. Note: These figures are provided on an actuarial basis and will be different from the funding levels identified in the CAFR which are prepared on an accounting basis. -5% 0% 5% 10% 15% 20% 2001 2002 2003 2004 2005 2006 2007 2008 2009 2010 2011 2012 2013 2014 2015 2016 2017 TMRS Investment Rate of Returns Net of Fees Date: July 27, 2018 Report No. 2018-096 Page | 3 DFRRF Overview: The Denton Firemen’s Relief and Retirement Fund (DFRRF) covers firefighters in the Denton Fire Department, and the Board of Trustees is the administrator of pension plan. The plan provides service, death, and disability benefits to members, and these benefits fully vest after 20 years of service. The normal service retirement benefit is equal to 2.59% of the highest 36-month average salary for each year of service under the plan. As of December 31, 2015, the most recent biennial valuation, the plan served 176 active firefighters and 84 retirees or beneficiaries. Additionally, 2 inactive employees are entitled to benefits, but they are currently not yet receiving them. Specific information for the City of Denton’s DFRRF is provided in the attached excerpt from the City’s Comprehensive Annual Financial Report (CAFR). As we have discussed with Council in the past, the TMRS plan experienced actuarial issues in 2008, and as a result, the City increased its contribution rate to the plan over time. There was, however, no increase in benefits provided in the plan. Instead, the increase in contributions was intended to reduce liabilities and improve the overall financial health of the plan. Due to the increases in the TMRS contribution rate, the Firefighters Association requested that the same contribution rate given to TMRS be provided to the DFRRF. In 2010, the City agreed to this arrangement. While this funding methodology worked well over the past few years, this arrangement needed to be modified due to changing demographics and the current investment climate. The primary reason for this change is that the City’s TMRS contribution is declining as a percentage of payroll due to growth in the municipal workforce. Additionally, the DFRRF needs a contribution from the City which is decoupled and independent of TMRS. To address this, the City, the Firefighters Association, and the DFRRF entered into an agreement in 2017 to revise the funding formula and require that the City Council formally approve the actuarial study every two years among other items. The actuarial study is currently in the process of being completed, and staff anticipates that this will be presented to the Council for consideration this fall. Additionally, staff has been working to address turnover and retention issues with our public safety dispatch employees. Currently, these employees are required to participate in the DFRRF, but due to the vesting requirements, relatively high employee contribution rate, and lack of portability between different cities, this can create challenges to attract and retain employees. As a result, staff has been working with the Fire Association and DFRRF Board to consider a potential agreement which would allow dispatch employees to choose between being a member of the DFRRF or TMRS plan. The actuarial impact of these changes is currently being studied, and we plan to present this information to the Council in either August or September once the results are known. For planning purposes, we have included an additional $200,000 in the proposed FY 2018- 19 budget should such a decision be made by the City Council to allow these benefit revisions. Date: July 27, 2018 Report No. 2018-096 Page | 4 Investment Performance The annual investment return assumption is 6.75% of plan assets. Like TMRS, the actuarial valuation process utilizes asset smoothing techniques to “smooth out” the natural year-to-year fluctuations that are inherent in the investment markets. Below is a 17 year history of the DFRRF investment rate of returns achieved compared to the stated goal of 6.75% (shown as a red line in the below graph). Over this period, DFRRF has achieved an average investment return equivalent to 6.16% (arithmetic average). While the plan has trailed its investment return assumption, the DFRRF Board of Trustees, and their actuarial consultants, believe they will be able to achieve an average 6.75% return over time. However, there is no guarantee that the DFRRF will be able to achieve these rates in the future. If they are not able to do so, the plan will need to alter the level of benefits or request a higher contribution rate from its members or the City. Similar to the TMRS plan, it is also important to note that any one year, or even a series of years, of below average investment returns is not a cause for alarm. The DFRRF is designed to provide benefits for employees and retirees over decades, and as such, a long-term view of investment performance assumptions is the proper way to evaluate the health of the plan. Actuarial Information and Funding Progress As of December 31, 2015, the most recent actuarial valuation, the City of Denton had an Actuarial Value of Assets (AVA) of $72.7 million and a Total Actuarial Accrued Liability (AAL) of $89.9 million for the DFRRF plan. This equates to an Unfunded Actuarial Accrued Liability (UAAL) of $17.2 million and a funded ratio of 80.8%, compared to 77.1% in 2013. The UAAL is being amortized over a period of 31 years in our existing contribution rate, so assuming all assumptions are met, the DFRRF plan for Denton will be 100% funded by 2046. However, if investment returns or other economic assumptions are not realized, the fund will amortize these actuarial differences over a longer period of time, and the full funding of the plan may be extended. As stated previously, the 2017 actuarial valuation is in process, and we expect to be able to present updated -15% -10% -5% 0% 5% 10% 15% 20% 2001 2002 2003 2004 2005 2006 2007 2008 2009 2010 2011 2012 2013 2014 2015 2016 2017 DFRRF Investment Rate of Returns Net of Fees Date: July 27, 2018 Report No. 2018-096 Page | 5 figures to the Council with the impact of the above mentioned contribution change in the fall of 2018. Note: These figures are provided on an actuarial basis and will be different from the funding levels identified in the CAFR which are prepared on an accounting basis. CONCLUSION: While public pensions continue to receive a great deal of media scrutiny, most public pension plans in Texas continue to be appropriately funded. In Denton’s case, both the TMRS and DFRRF plans are well funded and managed responsibly. Going forward, the funding ratios for these plans are expected to improve, and a financially sustainable funding mechanism is in place. As mentioned previously, the purpose of this report is to provide the City Council with additional information regarding the funding status of the TMRS and DFRRF pension plans. Since this report only provides an overview of the pension plans, please let me know if you would like any additional information. EXHIBITS: Exhibit 1: Excerpt from 2017 Comprehensive Annual Financial Report (CAFR) STAFF CONTACT: Bryan Langley, Deputy City Manager (940) 349-8224 bryan.langley@cityofdenton.com CITY OF DENTON, TEXAS NOTES TO BASIC FINANCIAL STATEMENTS (continued) SEPTEMBER 30, 2017 The solid waste fund has provided for a reservation and designation of cash and investments of $8,654,114 at September 30, 2017, and anticipates increasing the reserve in future periods as the closure and post-closure activities are carried out. V. OTHER INFORMATION A. Pension plans Texas Municipal Retirement Plan Plan description The City of Denton participates as one of 872 plans in the nontraditional, joint contributory, hybrid defined benefit pension plan administered by the Texas Municipal Retirement System (TMRS). TMRS is an agency created by the State of Texas and administered in accordance with the TMRS Act, Subtitle G, Title 8, Texas Government Code (the TMRS Act) as an agent multiple-employer retirement system for municipal employees in the State of Texas. The TMRS Act places the general administration and management of the System with a six-member board of Trustees. Although the Governor, with the advice and consent of the Senate, appoints the Board, TMRS is not fiscally dependent on the State of Texas. TMRS’s defined benefit pension plan is a tax-qualified plan under Section 401(a) of the Internal Revenue Code. TMRS issues a publicly-available comprehensive annual financial report (CAFR) obtainable at www.tmrs.com. All eligible employees of the city are required to participate in TMRS. Benefits provided TMRS provides retirement, disability, and death benefits. Benefit provisions are adopted by the governing body of the City, within the options available in the state statutes governing TMRS. At retirement, the benefit is calculated as if the sum of the employee’s contributions, with interest, and the city-financed monetary credits with interest were used to purchase an annuity. Members may choose to receive their retirement benefit in one of seven payments options. Members may also choose to receive a portion of their benefit as a Partial Lump Sum Distribution in an amount equal to 12, 24, or 36 monthly payments, which cannot exceed 75% of the member’s deposits and interest. Upon retirement, benefits depend on the sum of the employee’s contributions, with interest, and the city- financed monetary credits, with interest. City-financed monetary credits are composed of three sources: prior service credits, current service credits, and updated service credits. Prior service credit, granted by each city joining TMRS, is a monetary credit equal to the accumulated value of the percentage of prior service credit adopted times and employee’s deposits that would have been made, based on the average salary prior to participation, for the number of months the employee has been employed, accruing 3% annual interest, and including the matching ratio adopted by the City. Monetary credits for service since the plan began (or current service credits) are a percent (200%) of the employee's accumulated contributions. In addition, the City grants on an annually repeating basis, another type of monetary credit referred to as an updated service credit. This monetary credit is determined by hypothetically recomputing the member’s account balance by assuming the current member deposit rate of the City (7%) has always been in effect. The computation also assumes the member’s salary has always been the member’s average salary – using a salary calculation based on the 36- month period ending a year before the effective date of calculation. This hypothetical account balance is increased by 3% each year, and increased by the city match currently in effect (200%). The resulting sum is then compared to the member’s actual account balance increased by the actual city match and actual interest credited. If the hypothetical calculation exceeds the actual calculation, the member is granted a monetary credit (or Updated Service Credit) equal to the difference between the hypothetical calculation and the actual calculation times the percentage adopted. The plan provisions also include an annually repeating basis cost of living adjustments for retires equal to 70% of the change in the consumer price index. Members can retire at ages 60 and above with 5 or more years of service or with 20 years of service regardless of age. A member is vested after five years. 58 CITY OF DENTON, TEXAS NOTES TO BASIC FINANCIAL STATEMENTS (continued) SEPTEMBER 30, 2017 Employees covered by benefit terms At the December 31, 2016 valuation and measurement date, the following employees were covered by the benefit terms: Contributions The contribution rates for employees in TMRS are either 5%, 6%, or 7% of employee gross earnings, and the city matching percentages are either 100%, 150%, or 200%, both as adopted by the City Council. Under the state law governing TMRS, the contribution rate for each city is determined annually by the actuary, using the Entry Age Normal (EAN) actuarial cost method. The actuarially determined rate is the estimated amount necessary to finance the cost of benefits earned by employees during the year, with an additional amount to finance any unfunded accrued liability. Employees for the City were required to contribute 7% of their annual gross earnings during the fiscal year. The contribution rates for the City were 17.23% and 17.30% in calendar years 2016 and 2017, respectively. The City’s contributions to TMRS for the year ended September 30, 2017 were $14,648,606 and were equal to the required contributions. Net pension liability The City’s Net Pension Liability (NPL) was measured as of December 31, 2016, and the Total Pension Liability (TPL) used to calculate the Net Pension Liability was determined by an actuarial valuation as of that date. Actuarial assumptions The Total Pension Liability in the December 31, 2016 actuarial valuation was determined using the following actuarial assumptions: Inflation 2.5% per year Overall payroll growth 3.0% per year Investment Rate of Return 6.75%, net of pension plan investment expense, including inflation Salary increases were based on a service-related table. Mortality rates for active members, retirees, and beneficiaries were based on the gender-distinct RP2000 Combined Healthy Mortality Tables with Blue Collar Adjustment, with male rates multiplied by 109% and female rates multiplied by 103%. The rates are projected on a fully generational basis by scale BB to account for future mortality improvements. For disabled annuitants, the gender-distinct RP2000 Combined Healthy Mortality Tables with Blue Collar Adjustment are used with male rates multiplied by 109% and female rates multiplied by 103% with a 3-year set-forward for both males and females. In addition, a 3% minimum mortality rate is applied to reflect the impairment for younger members who become disabled. The rates are projected on a fully generational basis by scale BB to account for future mortality improvements subject to the 3% floor. Actuarial assumptions used in the December 31, 2016, valuation were based on the results of actuarial experience studies. The experience study in TMRS was for the period December 31, 2010 through December 31, 2014. Healthy post-retirement mortality rates and annuity purchase rates were updated based on a Mortality Experience Investigation Study covering 2009 through 2011, and dated December 31, 2013. These assumptions were first used in the December 31, 2013 valuation, along with a change to the Entry Age Normal Inactive employees or beneficiaries currently receiving benefits 520 Inactive employees entitled to but not yet receiving benefits 478 Active employees 1,245 Total 2,243 59 CITY OF DENTON, TEXAS NOTES TO BASIC FINANCIAL STATEMENTS (continued) SEPTEMBER 30, 2017 (EAN) actuarial cost method. Assumptions are reviewed annually. No additional changes were made for the 2014 valuation. After the Asset Allocation Study analysis and experience investigation study, the Board amended the long-term expected rate of return on pension plan investments from 7% to 6.75%. Plan assets are managed on a total return basis with an emphasis on both capital appreciation as well as the production of income, in order to satisfy the short-term and long-term funding needs of TMRS. The long-term expected rate of return on pension plan investments was determined using a building-block method in which best estimate ranges of expected future real rates of return (expected returns, net of pension plan 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. In determining their best estimate of a recommended investment return assumption under the various alternative asset allocation portfolios, TMRS’s actuary focused on the area between (1) arithmetic mean (aggressive) without an adjustment for time (conservative) and (2) the geometric mean (conservative) with an adjustment for time (aggressive). The target allocation and best estimates of real rates of return for each major asset class in fiscal year 2017 are summarized in the following table: Discount rate The discount rate used to measure the Total Pension Liability was 6.75%. The projection of cash flows used to determine the discount rate assumed that employee and employer contributions will be made at the rates specified in statute. Based on that assumption, the pension plan’s Fiduciary Net Position was projected to be available to make all projected future benefit payments of current active and inactive employees. Therefore, the long-term expected rate of return on pension plan investments was applied to all periods of projected benefit payments to determine the Total Pension Liability.

That report may be obtained on the Internet at www.tmrs.com. Pension expense and deferred outflows of resources and deferred inflows of resources related to pensions For the year ended September 30, 2017, the City recognized pension expense of $19,051,014. This amount is included as part of personal services expenses.

Other amounts reported as deferred outflows and inflows of resources related to pensions will be recognized in pension expense as follows: Supplemental death benefit fund The City of Denton also participates in the cost-sharing multiple-employer defined benefit group-term life insurance plan known as the Supplemental Death Benefits Fund (SDBF). This is a separate trust administered by the TMRS Board of Trustees and is a voluntary program in which the City elected, by ordinance, to provide group term life insurance coverage to active and retired members. The City may terminate coverage under and discontinue participation in the SDBF by adopting an ordinance before November 1st of any year to be effective the following January 1st. Payments from this fund are similar to group term life insurance benefits, and are paid to the designated beneficiaries upon the receipt of an approved application for payment. The death benefit for active employees provides a lump-sum payment approximately equal to the employee’s annual salary (calculated based on the employee’s actual earnings, for the 12-month period preceding the month of death). The death benefit for retirees is considered an “other postemployment benefit” (OPEB) and is a fixed amount of $7,500. The obligations of this plan are payable only from the SDBF and are not an obligation of, or claim against, the TMRS Pension Trust Fund. Contributions are made monthly based on the covered payroll of employee members of the City. The contractually required contribution rate is determined by an annual actuarial valuation and is based on the mortality and service experience of all employees covered by the SDBF and the demographics specific to the workforce of the City. There is a one-year delay between the actuarial valuation that serves as the basis for the employer contribution rate and the calendar year when the rate goes into effect.

The TMRS Act requires the Pension Trust Fund to allocate investment income to the SDBF on an annual basis. The funding policy of the plan is to assure adequate resources are available to meet all death benefit payments for the upcoming year; the intent is not to prefund retiree term life insurance during employees’ entire careers. As such, contributions are utilized to fund active member deaths on a pay-as-you-go basis; any excess contributions and investment income over payments then become net position available for OPEB. The City’s contributions to the TMRS SDBF for the fiscal years ended September 30, 2015, 2016, and 2017, were $133,686, $149,630, and $152,556, respectively, which equaled the required contributions each year. Denton Firemen's Relief and Retirement Plan Plan description The City contributes to the retirement plan for firefighters in the Denton Fire Department known as the Denton Firemen’s Relief and Retirement Fund (the Fund). The Fund is a single employer, contributory, defined benefit plan. The benefit provisions of the Fund are authorized by the Texas Local Fire Fighters’ Retirement Act (TLFFRA). TLFFRA provides the authority and procedure to amend benefit provisions. The plan is administered by the Board of Trustees of the Denton Firemen’s Relief and Retirement Fund. The City does not have access to nor can it utilize assets within the retirement plan trust. The Fund issues a stand-alone report pursuant to GASB Statement No. 67, which may be obtained by writing the Denton Firemen’s Relief and Retirement Fund at P.O. Box 2375, Denton, Texas 76202. See that report for all information about the plan fiduciary net position. Benefits provided Firefighters in the Denton Fire Department are covered by the Denton Firemen’s Relief and Retirement Fund which provides service retirement, death, disability, and withdrawal benefits. These benefits fully vest after 20 years of credited service. Firefighters may retire at age 50 with 20 years of service. A partially-vested benefit is provided for firefighters who terminate employment with at least 10 but less than 20 years of service. If a terminated firefighter has a partially vested benefit, the firefighter may retire starting on the date they would have both completed 20 years of service if they had remained a Denton firefighter and attained age 50. As of the December 31, 2015 actuarial valuation date, the plan effective January 1, 2011 provides a monthly normal service retirement benefit, payable in a Joint and Two-Thirds to Spouse form of annuity, equal to 2.59% of Highest 36-Month Average Salary for each year of service. A retiring firefighter who is at least age 52 with at least 22 years of service has the option to elect the Retroactive Deferred Retirement Option Plan (RETRO DROP) which will provide a lump sum benefit and a reduced monthly benefit. The reduced monthly benefit is based on the service and Highest 36-Month Average Salary as if the firefighter had terminated employment on their selected RETRO DROP benefit calculation date, which is no earlier than the later of the date the firefighter meets the age 52 and 22 years of service requirements and the date four years prior to the date the firefighter actually retires. Upon retirement, the member will receive, in addition to the monthly retirement benefit, a lump sum equal to the sum of (1) the amount of monthly contributions the member has made to the Fund after the RETRO DROP benefit calculation date plus (2) the total of the monthly retirement benefits the member would have received between the RETRO DROP benefit calculation date and the date retired under the plan. There are no account balances. The lump sum is calculated at the time of retirement and distributed as soon as administratively possible. There is no provision for automatic postretirement benefit increases. The Fund has the authority to provide, and has periodically in the past provided, ad hoc postretirement benefit increases. 63 CITY OF DENTON, TEXAS NOTES TO BASIC FINANCIAL STATEMENTS (continued) SEPTEMBER 30, 2017 Employees covered by benefit terms In the December 31, 2015 actuarial valuation, the following numbers of members were covered by the Fund: Contributions The contribution provisions of the Fund are authorized by TLFFRA. TLFFRA provides the authority and procedure to change the amount of contributions determined as a percentage of pay by each firefighter and a percentage of payroll by the City. The funding policy of the Denton Firemen’s Relief and Retirement Fund requires contributions equal to 12.6% of pay by the firefighters, the rate elected by the firefighters according to TLFFRA. The City currently contributes according to a City ordinance the same percentage of payroll the City contributes to the Texas Municipal Retirement System for other employees each calendar year. The City contribution rate was 17.41% in calendar year 2016 and 17.48% in calendar year 2017 until mid-December when the rate changed to 18.5%. The December 31, 2015 actuarial valuation includes the assumption that the city contribution rate will average 15.5% over the UAAL amortization period. The costs of administering the plan are paid from the Fund assets. The City’s contributions to the Fund for the year ended September 30, 2017 were $2,814,029. Ultimately, the funding policy also depends upon the total return of the Fund’s assets, which varies from year to year. Investment policy decisions are established and maintained by the board of trustees. The board selects investments and employs investment managers with the advice of their investment consultant who is completely independent of the investment managers. For the calendar year ending December 31, 2016, the money-weighted rate of return on pension plan investments was 10.17%. This measurement of the investment performance is net of investment-related expenses, reflecting the effect of the timing of the contributions received and the benefits paid during the year. While the contribution requirements are not actuarially determined, state law requires that each change in plan benefits adopted by the Fund must first be approved by an eligible actuary, certifying the contribution commitment by the firefighters and the assumed city contribution rate together provide an adequate contribution arrangement. Using the entry age actuarial cost method, the plan’s normal cost contribution rate is determined as a percentage of payroll. The excess of the total contribution rate over the normal cost contribution rate is used to amortize the plan’s unfunded actuarial accrued liability (UAAL). The number of years needed to amortize the plan’s UAAL is actuarially determined using an open, level percentage of payroll method. Net pension liability The City of Denton’s net pension liability was measured as of December 31, 2016, and the total pension liability used to calculate the net pension liability was determined by an actuarial valuation as of December 31, 2015 and rolled forward to December 31, 2016. Actuarial assumptions The total pension liability in the December 31, 2015 actuarial valuation was determined using the following actuarial assumptions, applied to all periods included in the measurement: Inflation 2.50% per year Overall payroll growth 3.00% per year, plus promotion, step and longevity increases that vary by service Investment Rate of Return 6.75%, net of pension plan investment expense, including inflation Inactive employees or beneficiaries currently receiving benefits 84 Inactive employees entitled to but not yet receiving benefits 2 Active employees 176 Total 262 64 CITY OF DENTON, TEXAS NOTES TO BASIC FINANCIAL STATEMENTS (continued) SEPTEMBER 30, 2017 Mortality rates were based on the RP-2000 Combined Healthy Mortality Tables for males and for females (sex distinct) projected to 2024 by scale AA. The long-term expected rate of return on pension plan investments is reviewed for each biennial actuarial valuation and was determined using a building-block method in which expected future net real rates of return (expected returns, net of pension plan investment expense and inflation) are developed for each major asset class. These components are combined to produce the long-term expected rate of return by weighting the expected future net real rates of return by the target asset allocation percentage (currently resulting in 5.00%) and by adding expected inflation (2.50%). In addition, the final 6.75% assumption was selected by “rounding down” and thereby reflects a reduction of 0.75% for adverse deviation. The target allocation and expected arithmetic net real rates of return for each major asset class are summarized in the following table: Discount rate The discount rate used to measure the total pension liability was 6.75%. No projection of cash flows was used to determine the discount rate because the December 31, 2015 actuarial valuation showed expected contributions would pay the normal cost and amortize the unfunded actuarial accrued liability (UAAL) in 32 years. Because of the 32-year amortization period of the UAAL, the pension plan’s fiduciary net position is expected to be available to make all projected future benefit payments of current active and inactive members. Therefore, the long-term expected rate of return on pension plan investments of 6.75% was applied to all periods of projected benefit payments as the discount rate to determine the total pension liability.

Detailed information about the plan fiduciary net position is available in the Fund’s separately issued audited financial statements, which are reported using the economic resources measurement focus and the accrual basis of accounting in conformity with accounting principles generally accepted in the United States of America. Revenues are recorded when earned, and expenses are recorded when a liability is incurred, regardless of the timing of the related cash flows. Investments are reported at fair value, the price that would be recognized to sell an asset in an orderly transaction between market participants at the measurement date. Pension expense and deferred outflows of resources and deferred inflows of resources related to pensions For the year ended September 30, 2017, the City recognized pension expense of $3,983,918. Amounts recognized in the fiscal year represent changes between the current and prior year measurement dates. This amount is included as part of personnel services expenses.

Other amounts reported as deferred outflows and inflows of resources related to pensions will be recognized in pension expense as follows: B. Post-employment benefits other than pensions (OPEB) The cost of post-employment healthcare benefits, from an accrual accounting perspective, similar to the cost of pension benefits, should be associated with the periods in which the cost occurs, rather than in the future year when it will be paid. According to the requirements of GASB Statement No. 45 for the fiscal year ended September 30, 2017, the City recognizes the cost of post-employment healthcare in the year the employee services are received, reports the accumulated liability from prior years, and provides information useful in assessing potential demands on the City’s future cash flows. Recognition of the liability accumulated from prior years will be amortized over 30 years, the first period commencing with the fiscal year ending September 30, 2008. Plan description The City provides post-employment medical care (OPEB) for retired employees through a single-employer defined benefit medical plan. The plan provides medical benefits for eligible retirees, their spouses and dependents though the City’s group health insurance plans, which covers both active and retired members. The benefits, benefit levels, and contribution rates are recommended annually by the City management as part of the budget process. Any changes in rate subsidies for retirees are approved by the City Council.
