The City selected Gabriel, Roeder, Smith & Company (GRS) to perform the actuarial audit. The project commenced in February of 2025. This Actuarial Audit includes the following: • Comparison and reconciliation of census data provided by DFRRF and that used by the consulting actuary for preparing the actuarial valuation. • Review and analysis of the valuation results as well as a review of the mathematical calculations for completeness and accuracy, based on a detailed review of a representative sample of the current plan participants. • Verification that all appropriate benefits have been valued and valued accurately. • Evaluation of the actuarial cost method and the actuarial asset valuation method in use and whether other methods may be more appropriate for DFRRF. • Verification of the reasonableness of the calculation of the unfunded actuarial accrued liability and the amortization period used under the actuarial cost method. • Review of the demographic and economic actuarial assumptions for consistency, reasonableness and compatibility. Such assumptions shall include, but are not limited to: mortality, retirement and separation rates, levels of pay adjustments, rates of investment return, and disability factors. • Assessment of the adherence to relevant Actuarial Standards of Practice (ASOPs) published by the American Academy of Actuaries. • Assessment of the adherence to the Texas Pension Review Board (PRB) Pension Funding Guidelines. This actuarial audit will satisfy the requirements of Section 802.1012 of the Texas Government Code which requires an actuarial audit of public retirement systems in Texas with total assets of at least$100 million every five years. Summary of Findings Based on our review, the actuarial valuation, studies, and reports of the Plan are reasonable, used appropriate assumptions and adhered to Actuarial Standards of Practice and Texas PRB Pension Funding Guidelines. We offer the following recommendations based on the valuation methods and assumptions used by the retained actuary in the December 31, 2023 actuarial valuation. Actuarial Assumptions • During the preparation of this actuarial audit, the retained actuary informed us that an actuarial experience study was planned for later this year. Had this not come to light, this would have been a primary recommendation. Thus, we recommend the retained actuary, the City, and the Fund carry out and complete this project as planned. More specifically, we recommend formal analyses C $ Denton Firemen's Relief and Retirement Fund 2 Report of an Actuarial Audit of demographic assumptions, including but not limited to: retirement rates, termination rates, disability rates, individual salary increases, and mortality assumptions which include whether the more current Pub-2016 mortality tables and mortality improvement assumptions are more appropriate. • When preparing the actuarial experience study, we recommend the retained actuary consider extending the number of years for which Merit, Promotion, and Longevity increases apply (if supported by the Plan's experience). Actuarial Methods and Funding Policy • No Recommendations. Actuarial Valuation Results • We believe that the valuation results were developed in a reasonable manner based on the current application of the methods. No Recommendations. Content of Valuation Report • Beyond the investment return scenarios shown on p. 3, we recommend the retained actuary expand its disclosures and risk metrics under the guidance of ASOP 51. As an example, this may include a historical table of plan maturity metrics such as: o the ratio of market value of assets to active participant payroll, o the ratio of retired life actuarial accrued liability to total actuarial accrued liability o the ratio of a cash flow measure (such as benefit payments, or contributions less benefit payments) to market value of assets o the ratio of benefit payments to contributions o the duration of the actuarial accrued liability • We recommend providing a reference to the origin of assumptions, whether it be to a formal experience study, published table, or acquired from prior actuary. • We recommend additional disclosures to the summary of Actuarial Methods and Assumptions (Exhibit 11) to include: o Decrement timing o Timing of individual salary increases 4�w Denton Firemen's Relief and Retirement Fund 3 Report of an Actuarial Audit SECTION B GENERAL ACTUARIAL AUDIT PROCEDURE General Actuarial Audit Procedure At the commencement of this engagement, GRS requested the information necessary to thoroughly review the work product of the retained actuary. Specifically, GRS received and reviewed the following items: • Actuarial valuation report as of December 31, 2023, • The Fund's Investment Policy Statement, revised February 19, 2020, • The Denton Firemen's Relief and Retirement Fund Plan, effective January 1, 2011 • Civil Service Fire Pay Plan, effective January 7, 2023, • Civil Service Fire Pay Plan, effective February 6, 2024, • DFRRF census data as of December 31, 2023, • DFRRF Salary& Contributions from January 1, 2023 through December 31, 2023, • Northern Trust Pension Benefit Payment Register, dated as of December 19, 2023, and • Calculations from the retained actuary for a sampling of 22 plan participants as of December 31, 2023. Note: GRS requested the most recent experience study. However, a formal experience study has yet to be performed but is expected in 2025. The retained actuary provided an analysis of economic assumptions in the valuation report, which was reviewed by GRS. In performing our review, we: • Reviewed the plan document to understand the benefits provided by the Plan, • Reviewed the appropriateness of the actuarial assumptions, • Reviewed the census data for basic demographic statistics (statuses, pay, benefits, payment forms, etc.), • Reviewed the actuarial reports/studies, and • Reviewed the detailed liability calculation of the sample test lives to ensure that the calculations were consistent with the stated plan provisions, actuarial methods and assumptions. The entire review, which follows, is based on our review of this information and subsequent correspondence with the City, DFRRF, and the retained actuary for clarification and further documentation. Key Actuarial Concepts An actuarial valuation is a detailed statistical simulation of the future operation of a retirement plan using the set of actuarial assumptions adopted by the plan sponsor. It is designed to simulate all of the dynamics of such a retirement plan for each current participant of the plan, including: • Accrual of future service, • Changes in compensation, • Leaving the plan through retirement, disability, withdrawal, or death, and 4�w Denton Firemen's Relief and Retirement Fund 5 Report of an Actuarial Audit • Determination of and payment of benefits from the plan. This simulated dynamic is applied to each active participant of the plan. This simulation results in a set of expected future benefit payments to that participant. Discounting those future payments for the likelihood of survival and at the assumed rate of investment return, produces the Total Present Value of Plan Benefits (TPV) for that participant. The actuarial cost method will allocate this TPV between the participant's past service (actuarial accrued liability) and future service (future normal costs). PRB Pension Funding Guidelines During our actuarial audit of the Plan, we reviewed the actuarial valuation of the Plan from the perspective of the Texas Pension Review Board's "Guidance for Developing a Funding Policy", as adopted July 25, 2024. Note: Although this document was adopted after the valuation date of the report being reviewed in this audit, it was dated prior to the date of the valuation report of September 16, 2024. Furthermore, we believe this version of the Funding Policy Guidance is most appropriate for prospective reports should any changes to funding policies be recommended. The Guidelines state that a funding policy should: 1. Adhere to Texas Government Code, Section 802.2011, which requires the governing board of a Texas public retirement system and, if the system is not a statewide system, its sponsor to jointly develop and adopt the same written funding policy and timely revise the policy to reflect any significant changes, including those made because of a funding soundness restoration plan (FSRP). 2. Strive to balance the following three primary funding goals: benefit security, contribution security, and intergenerational equity. 3. Include clear and concrete funding objectives: a. Must target a funded ratio of 100 percent or greater and be jointly developed and adopted with the system's sponsor. 4. Select actuarial methods. The system's actuary should be involved in an advisory role. a. At a minimum, the three actuarial methods that should be addressed are the actuarial cost method, the asset-smoothing method, and the amortization policy. 5. Develop a roadmap to achieve funding objectives. A funding policy should provide a clear plan detailing how the system's funding goals will be met. This may include: a. Contribution rate structure i. If an Actuarial Determined Contribution (ADC) structure is not used, the funding policy should determine an ADC as a benchmark to monitor if actual contributions will satisfy funding objectives. b. Benefit and contribution change parameters. c. Working with the Sponsor d. Monitoring and evaluation 4�w Denton Firemen's Relief and Retirement Fund 6 Report of an Actuarial Audit 6. Adopt actions that will be taken to address actual experience that diverges from assumptions. This may include: a. Risk sharing b. Contributions c. Benefits d. Surplus Management These key actuarial concepts will be discussed in more detail throughout this report. 4�w Denton Firemen's Relief and Retirement Fund 7 Report of an Actuarial Audit SECTION C ACTUARIAL ASSUMPTIONS Actuarial Assumptions Overview The actuarial valuation report contains a description of the actuarial assumptions which were used in the actuarial valuation as of December 31, 2023. Within this report (Appendix A) the retained actuary provides a Review of the Actuarial Economic Assumptions. Additionally, the retained actuary states in its report: "We review the termination and retirement experience since the prior valuation and periodically look back more than two years. We also periodically review the average salaries by years of service to get insights into the promotion, step, and longevity compensation patterns for the purpose of reviewing our compensation increase assumption." During the preparation of this actuarial audit, the retained actuary informed us that an actuarial experience study was planned for later this year. We have reviewed the assumptions section of the valuation report and the analysis in Appendix A in detail in order to assess the reasonableness of the assumptions used in the actuarial valuation. The set of actuarial assumptions is one of the foundations upon which an actuarial valuation is based. An actuarial valuation is, essentially, a statistical projection of the amount and timing of future benefits to be paid under the retirement plan. In any statistical projection, assumptions as to future events will drive the process. Actuarial valuations are no exception. It is important to understand the nature of the retirement plan and the plan sponsor when assessing the reasonableness of the actuarial assumptions. No projection of future events can be labeled as "correct" or "incorrect". However, there is a "range of reasonableness" for each assumption. We evaluate individual elements as follows: • Whether or not they fall within the range of reasonableness, and • If they fall within that range, whether they are reasonable for the actuarial valuation of the Plan. Actuarial assumptions for the valuation of retirement plans are of two types: (i) demographic assumptions, and (ii) economic assumptions. We have assessed the reasonableness of both types as part of this actuarial audit. Demographic Assumptions General These assumptions simulate the movement of participants into and out of plan coverage and between status types. Key demographic assumptions are: • turnover among active participants, • retirement patterns among active participants, and • healthy retiree mortality. In addition, there are a number of other demographic assumptions with less substantial impact on the results of the process, such as: 4�� Denton Firemen's Relief and Retirement Fund 9 Report of an Actuarial Audit • disability incidence and mortality among disabled benefit recipients, • mortality among active participants, • distribution of form of payment selection, and • percent of active participants who are married and the relationship of the ages of participants and spouses. Demographic assumptions for a retirement plan such as DFRRF are normally established by statistical studies of recent actual experience, called experience studies. Such studies underlie the assumptions used in the valuations. The measurement of experience is normally affected by simply counting occurrences of an event. Thus, for example, in reviewing retirement patterns, an actuary might count the number of actual retirees among males aged 55 with 30 years of service. These retirements would be compared against the number of total people in that group to generate a raw rate of retirement for that group. Once it is determined whether or not an assumption needs adjustment, setting the new assumption depends upon the extent to which the current experience is an indicator of the long-term future. • Full credibility may be given to the current experience. Under this approach, the new assumptions are set very close to recent experience. • Alternatively,the recent experience might be given only partial credibility. Thus, the new assumptions may be set by blending the recent experience with the prior assumption. • If recent experience is believed to be atypical of the future, such knowledge is taken into account. • Finally, it may be determined that the size of the plan does not provide a large enough sample to make the data credible. In such cases, the experience of the plan may be disregarded and the assumption is set based upon industry standards for similar groups. Experience Study Texas Government Code Section 802.1014 states: "a public retirement system that has assets of at least $100 million shall conduct once every five years an actuarial experience study and shall submit to the board a copy of the actuarial experience study before the 31st day after the date of the study's adoption." The market value of assets of DFRRF has exceeded the $100 million threshold since the December 31, 2019 actuarial valuation (however the actuarial value of assets has only exceeded $100 million since the December 31, 2021 actuarial valuation), and thus the Fund is currently subject to the requirements under Sec. 802.1014. Dating back to the December 31, 2017 actuarial valuation, the retained actuary has provided a Review of the Actuarial Economic Assumptions in Appendix A of its valuation report. The analyses in Appendix A have included a review of gross investment returns (and net of investment expenses), price inflation, and administrative expenses. We believe this satisfies applicable Actuarial Standards of Practice and the requirements outlined in Texas Government Code Section 802.1014. Under Section B of Exhibit 11:Actuarial Methods and Assumptions of the December 31, 2023 actuarial valuation report the retained actuary states: "We review the termination and retirement experience since the prior valuation and periodically look back more than two years. We also periodically review the 4�w Denton Firemen's Relief and Retirement Fund 10 Report of an Actuarial Audit average salaries by years of service to get insights into the promotion, step, and longevity compensation patterns for the purpose of reviewing our compensation increase assumption." Although we believe the retained actuary's periodic internal review of these assumptions satisfy applicable Actuarial Standards of Practice, it is unclear if the requirements outlined in Texas Government Code Section 802.1014 have been satisfied given there has not been a formal experience study report illustrating and/or describing observed data regarding these and other demographic assumptions. Given the PRB's guidelines and knowing that an experience study is expected to be prepared later this year,we recommend the retained actuary,the City, and the Fund collaborate to carry out this project as planned. Observations on Assumptions We acknowledge that valuations performed on a biennial frequency pose a challenge from an actuary's perspective in regard to measuring demographic gains and losses, as well as simply compiling sufficient data (i.e. exposures, actual counts, and expected counts) necessary to perform experience studies, given that rates used for demographic assumptions are on an annual basis. Thus, there are "gaps" that must be filled in order to align actual outcomes with expected outcomes. Overall, it appears that the current demographic assumptions are reasonable. However, we did notice that several primary assumptions (specifically retirement rates, termination rates, disability rates, and individual salary increases) have been unchanged since at least the December 31, 2015 actuarial valuation. It is important to note that this does not imply these assumptions are not appropriate. This does, however, reinforce our recommendation for the retained actuary to perform the formal experience study as planned to ensure the continued appropriateness of these assumptions or recommend adjustments as necessary. Below, we offer general observations and considerations for the retained actuary based on our experiences with similar plans. Retirement—The current assumption contains rates that increase incrementally from 5%to 15%to 30% to 50%from the ages of 50 to 64 with an ultimate rate of 100% at age 65. While this assumption is completely reasonable, we have observed that public safety plans that allow for normal retirement at relatively young ages (i.e. attainment of age 50 with 20 years of service for DFRRF) tend to have "spikes" in retirement behavior at certain ages or eligibilities. For example, we may anticipate a spike at the maximum RETRO DROP eligibility of age 56 and 26 years of service (assuming 20 years was attained by age 50). We recommend this be observed and measured in the formal experience study. Turnover—We believe the current termination rates follow a reasonable decreasing pattern. We have observed that in firefighter plans that as new firefighters experience the physical and mental demands and qualifications of the occupation, this often causes even higher turnover in the first two to three years, but level off significantly once the employee has established themselves in the routine of the occupation and purse a long-term career. Again, we recommend this be observed and measured in the formal experience study. Disability Incidence— In general,very little retirement plan experience exists in order to set a reasonable assumption based on actual retirement plan experience. The current assumption is reasonable and within 4�w Denton Firemen's Relief and Retirement Fund 11 Report of an Actuarial Audit industry standards. This assumption is less material than others and we have no further comment regarding this assumption. Mortality—The main demographic assumption in an actuarial valuation is the rates of mortality because this assumption is a predictor of how long pension payments will be made by the trust. The current mortality assumption for active participants, healthy annuitants, and disabled annuitants is based on the gender distinct Pub-2010 Safety Employees Mortality Tables with generational mortality improvements using Scale MP-2019. We concur that the Pub-2010 Safety tables are appropriate tables. However,we recommend the retained actuary consider using the disabled lives subset for current and future disabled retirees and whether the more current Pub-2016 mortality tables and mortality improvement assumptions developed by the Society of Actuaries are more appropriate when preparing the experience study. RETRO DROP Election —The current assumption is 100% of service retirements eligible to elect at least a 12-month lump sum and that participants will elect the maximum allowable months (up to 48 months). Without historical statistics to confirm actual behavior, we believe this is an appropriate assumption. Percent Married—We have confirmed the 90% married assumption at retirement reasonably aligns with the distribution of forms of payment in the December 31, 2023 census data. Economic Assumptions General These assumptions simulate the impact of economic forces on the amounts and values of future benefits. Key economic assumptions are the assumed rate of investment return and assumed rates of future salary increase. All economic assumptions are built upon an underlying inflation assumption. Inflation Inflation refers to mean price inflation as measured by annual increases in the Consumer Price Index (CPI). This inflation assumption underlies most of the other economic assumptions. It primarily impacts investment return and salary increases. The current explicit inflation assumption is 2.50%. This inflation assumption has been in effect since at least the December 31, 2015 actuarial valuation and was recommended to stay in effect based on analysis shown in Appendix A of the December 31, 2023 valuation report. In our review of the 2024 capital market assumption sets for the twelve investment consulting firms listed on the next page,the average assumption for inflation was approximately 2.39%, with a range of 2.13%to 2.70%. It should be noted that all of these investment consulting firms set their assumptions based on approximately a ten-year outlook, while actuaries generally must make longer projections. G R S Denton Firemen's Relief and Retirement Fund 12 Report of an Actuarial Audit In the Social Security Administration's 2024 Trustees Report, the Office of the Chief Actuary projected a long-term average annual inflation rate of 2.4% under the intermediate cost assumption. (The low-cost assumption was 3.0% and the high cost assumption was 1.8%).These inflation assumptions forecasts have not materially changed for several years, as they were the same rates as in the corresponding reports from 2020 through 2023. The Philadelphia Federal Reserve conducts a quarterly survey of the Society of Professional Forecasters. In their forecast immediately preceding the December 31, 2023 actuarial valuation, fourth quarter of 2023, was for inflation over the next ten years to average 2.40%. Over the shorter term, the society of Professional Forecasters are predicting inflation to average 2.5%and 2.3%for the calendar years 2024 and 2025, respectively. We consider the 2.50% assumption to be within the reasonable range. However,given developments of high inflation in recent years, we also recommend that the retained actuary continue to monitor this assumption (which they appear to be doing annually) to ensure that it remains within a reasonable range. Investment Return The investment return assumption is one of the principal assumptions in any actuarial valuation of a retirement plan. It is used to discount future expected benefit payments to the valuation date, in order to determine the liabilities of the retirement plan. Even a small change to this assumption can produce significant changes to the liabilities and contribution rates. The current assumption incorporates inflation of 2.50% per annum plus an annual real rate of return of 4.25%, net of investment-related expenses paid from the trust, for an assumed nominal rate of return of 6.75%. We believe an appropriate approach to reviewing an investment return assumption is to determine the median expected portfolio return given the retirement plan's target allocation and a given set of capital market assumptions. Per the Plan's Investment Policy Statement, revised February 19, 2020, the Plan's current target asset allocation is: Asset Class Target% Range % Domestic Large-Cap 40 25-50 Domestic Small & Mid-Cap 10 5-15 International Equity 10 5-15 Fixed Income 15 5-20 Cash and Equivalents 2 1-15 Alternative Investments 8 5-10 Real Estate 15 10-20 Because GRS is a benefit consulting firm and does not develop or maintain our own capital market assumptions, we reviewed assumptions developed and published by the following investment consulting firms: • Aon • Meketa • Black Rock • Mercer • BNY Mellon • NEPC 4�w Denton Firemen's Relief and Retirement Fund 13 Report of an Actuarial Audit • Callan • Northern Trust • Cambridge • Verus • JP Morgan • Wilshire These investment consulting firms periodically issue reports that describe their capital market assumptions, that is, their estimates of expected returns, volatility, and correlations. While these assumptions are developed based upon historical analysis, many of these firms also incorporate forward looking adjustments to better reflect near-term expectations. The estimates for core investments (i.e. fixed income, equities, and real estate) are generally based on anticipated returns produced by passive index funds. In addition to examining the expected geometric return, it is important to review anticipated volatility of the investment portfolio and understand the range of long-term net return that could be expected to be produced by the investment portfolio. Therefore, the following table provides the 401", 50t", and 60t" percentiles of the 20-year geometric average of the expected nominal return, net of investment-related expenses paid from the trust, as well as the probability of exceeding the current 6.75%assumption. Capital Market Distribution of 20-Year Average Geometric Probability of Assumption Net Nominal Return exceeding Set(CMA) 40th 50th 60th 6.75% (1) (2) (3) (4) (5) 1 4.20% 4.89% 5.58% 24.85% 2 4.65% 5.38% 6.11% 31.83% 3 5.24% 5.93% 6.63% 38.41% 4 5.55% 6.27% 6.99% 43.28% 5 5.89% 6.57% 7.26% 47.38% 6 6.04% 6.74% 7.44% 49.82% 7 6.07% 6.77% 7.48% 50.30% 8 6.09% 6.81% 7.54% 50.83% 9 6.34% 7.00% 7.66% 53.83% 10 6.41% 7.11% 7.82% 55.16% 11 6.56% 7.21% 7.86% 57.09% 12 6.72% 7.43% 8.13% 59.62% Average 1 5.81% 6.51% 7.21% 46.9% The table above shows that the resulting 20-year geometric average of the expected nominal return is 6.51%. Additionally, the table above documents that the average probability of exceeding the current 6.75% investment return assumption over a 20-year period is 46.9%. As an additional point of reference, the average one-year arithmetic return of the 12 investment consultants was 7.23%. However, looking back over previous years of capital market assumptions, the three-year average of arithmetic returns from 2022 through 2024 is 6.80%. This illustrates how short-term outlooks can change significantly from one year to the next. The current investment return assumption falls within an appropriate range and we believe that the assumption is reasonable for this purpose. G R S Denton Firemen's Relief and Retirement Fund 14 Report of an Actuarial Audit Earnings Progression In general, assumed rates of pay increase are often constructed as the total of three main components: • Price inflation —currently 2.50% • Economic Productivity Increases—currently 0.50% • Merit, Promotion, and Longevity—This portion of the salary increase assumption reflects components such as promotional increases as well as increases for merit and longevity. This portion of the assumption is not related to inflation. The current assumptions vary this component based on the participant's years of service. In the context of a typical employer pay scale, pay levels are set for various employment grades. In general, this pay scale is adjusted as follows: • The inflation and economic productivity assumptions, collectively referred to as wage inflation, reflect the overall increases of the entire pay scale, and • The Merit, Promotion, and Longevity increase assumption reflects movement of participants through the pay scale. Based on the building block approach outlined above, the earnings progression assumption is based on the sum of the expected pay increases related to wage inflation plus a component for merit, promotion and longevity. We find that the current 3.00%wage inflation (2.50% price inflation plus 0.50% economic productivity) is reasonable for this plan. Currently, the Merit, Promotion, and Longevity increases (combined as a single rate), range from 6.00% for the first five years, 3.00%for the next ten years, and 0%thereafter.These rates are compounded with the 3.00%wage inflation assumption. As previously noted in this audit report, there has been no formal experience study in which we can validate actual data supporting this assumption. However, based on our experience with similar plans and known pay scales, such as the "2024 Civil Service Pay Plan" provided by the Fund, we believe the current assumption is within the range of reasonableness for the purpose of the intended measurements. Nonetheless, we once again recommend a careful review of this assumption by the retained actuary in the upcoming experience study. Below we offer some general comments the retained actuary may wish to consider in their review. The current assumption follows an incrementally decreasing pattern of salary increases over a person's career. This is the standard for most plans and may well continue to be the most appropriate. However, in our experience with a relatively homogenous workforce and a clearly defined hierarchy, an observation of a mid-career pay spike from certain promotions may be relevant. In other words, how many firefighters advance through the ranks and at what point in their career does that typically happen? Each promotion 4�w Denton Firemen's Relief and Retirement Fund 15 Report of an Actuarial Audit in title (i.e. Firefighter to Driver to Lieutenant to Fire Captain to Fire Battalion Chief, etc.) may come with a significant pay increase. For example, moving from Step C (4+years) as Fire Captain to Step A of Fire Battalion Chief comes with a 7.9% increase in pay. After how many years of service does this promotion typically take place, what proportion of employees reach this promotion, and is it in alignment with the Merit, Promotion, and Longevity increase assumptions? In the current assumptions, the Merit, Promotion, and Longevity increases end after 15 years of service. This essentially implies that no employees get promotions after 15 years of service. Does this align with the timing of actual promotions indicated in the Civil Service Fire Pay Plan hierarchy? If not, we recommend extending this component to greater than 15 years of service. We find that when it comes to salary increases, a longer duration than the typical four to five years of experience utilized in experience studies illustrates the economic cycle for compensation (e.g. eight to ten years). Based on data provided during this audit, it appears the retained actuary has maintained an extensive amount of historical pay. In the upcoming experience study, we recommend that the retained actuary consider utilizing eight to ten years of salary data to analyze compensation increases, as well as consider extending the number of years for which Merit, Promotion, and Longevity increases apply. Summary The set of actuarial assumptions and methods, taken in combination, are within the range of reasonableness and established in accordance with ASOP No. 27, Selection of Economic Assumptions for Measuring Pension Obligations, ASOP No. 35, Selection of Demographic and Other Noneconomic Assumptions for Measuring Pension Obligations, and the Texas PRB Guidelines for Actuarial Soundness. We have the following recommendations regarding the actuarial assumptions: (1) In the next experience study, we recommend the retained actuary consider using the disabled lives subset for current and future disabled retirees and updating the mortality improvement table to the most recent version of the MP tables. (2) In the next experience study, we recommend the retained actuary consider that observations of atypical patterns (i.e. other than strictly increasing or decreasing) for certain assumptions, specifically retirement rates and salary increases, may be valid and appropriate to use. (3) In the next experience study, we recommend the retained actuary utilize a longer duration of data (eight to ten years) for the purpose of determining individual salary increases, as well as consider extending the number of years for which Merit, Promotion, and Longevity increases apply. 4�� Denton Firemen's Relief and Retirement Fund 16 Report of an Actuarial Audit SECTION D ACTUARIAL METHODS AND FUNDING POLICY Actuarial Methods and Funding Policy Actuarial Cost Methods General The ultimate cost of the Plan is equal to the benefits paid plus the expenses related to operating the Plan. This cost is funded through contributions to the Plan plus the investment return on accumulated contributions which are not immediately needed to pay benefits or expenses. The level and timing of the contributions needed to fund the ultimate cost are determined by the actuarial assumptions, plan provisions, participant characteristics, investment experience, and the actuarial cost method. An actuarial cost method is a mathematical process for allocating the dollar amount of the Total Present Value of Plan Benefits (TPV) between future normal costs and the Actuarial Accrued Liability (AAL). The retained actuary uses the Entry Age Normal actuarial cost method, characterized by: (1) Normal Cost (NC) —the level percent of payroll contribution, paid from each participant's date of hire to date of retirement, which will accumulate enough assets at retirement to fund the participant's projected benefits from retirement to death. (2) Actuarial Accrued Liability—the excess of the TPV over the present value of all future remaining normal costs. The Entry Age Normal actuarial cost method is the most prevalent funding method in the public sector. It is appropriate for the public sector because it produces costs that remain relatively stable as a percentage of payroll over time, resulting in intergenerational equity for taxpayers. Historically, most public plans have used the Entry Age Normal actuarial cost method. Therefore, the retained actuary's stated methods for allocating the liabilities of the Plan are certainly in line with national trends. Comments on the Cost Method We believe that the use of the Entry Age Normal actuarial cost method is reasonable in this situation. Asset Valuation Method Sharp short-term swings in market value can result in large fluctuations in the contributions required to fund the Plan. Thus, many actuaries use an asset valuation method which smooths out these fluctuations in support of achieving level contributions. A good asset valuation method places values on a retirement plan's assets which are related to current market value but which will also produce a smoother pattern of costs. ASOP No. 44, Selection and Use of Asset Valuation Methods for Pension Valuations, provides a framework for the determination of the actuarial value of assets (AVA) emphasizing that the method should bear a reasonable relationship to the market value of assets (MVA), recognize investment gains and losses over 4�� Denton Firemen's Relief and Retirement Fund 18 Report of an Actuarial Audit an appropriate time period, and avoid systematic bias that would overstate or understate the AVA in comparison to MVA. The actuarial valuation of the Plan currently utilizes a smoothed asset valuation method that immediately recognizes income equal to the expected return on valuation assets, based on the assumed valuation interest rate (6.75%). Differences between the assumed investment return on valuation assets and the actual market investment return is recognized over a five-year period. Further, the AVA is constrained to be within 90% and 110% of the MVA. This "corridor" assures that the AVA will always be within a reasonable range around the MVA. The smoothing method used for the actuarial valuation of the Plan is very common among public employee retirement systems. We feel that this method complies with ASOP No. 44, Selection and Use of Asset Valuation Methods for Pension Valuations. Additionally, this method is reasonable and appropriately applied for the valuation. Funding Policy As stated in the retained actuary's December 31, 2023 valuation report, the City's funding policy for the Denton Firefighter's Relief and Retirement Fund is: "a modified actuarially determined contribution rate(ADCR). Under that policy, the city's initial contribution rate was set at 18.5%and is to be re-evaluated by the city council following every actuarial valuation. The funding policy has the intent of paying off the unfunded actuarial accrued liability(UAAL)over a closed 25-year period or sooner. The policy language implies that the rate should stay at 18.5%for at least the first five years, even if the ADCR is less than 18.5% in order to pay down the UAAL. A key requirement of the policy is city approval of any change to the contribution level. The funding policy begins with the 18.5%city contribution rate, has an ADCR over a closed 25-year period we assume began January 1, 2018, but in no event will the city contribution rate be less than the contribution rate to its TMRS plan for the other city employees. The ADCR over the 19 years remaining in the closed period as of December 31, 2023 is 13.33%based on this actuarial valuation. The TMRS rate for the year beginning January 1, 2024 is 18.94%and for the year beginning January 1, 2025 is 18.88%."' Although the ADCR is slightly above the 18.5%floor,the retained actuary assumes contributions of 18.5% of pay for the purpose of determining the amortization period of the Unfunded Actuarially Accrued Liability ("UAAL"). We believe this approach is reasonable and provides some conservatism for potential adverse experience. We believe the retained actuary's summary accurately describes the funding policy laid out in Article 12 of the Meet and Confer Agreement approved September 19, 2023. Furthermore, we believe the funding policy in Article 12 complies with the provisions of the Plan and the Texas PRB's Guidance for Developing a Funding Policy. Additionally, on pages 1 and 2 of the valuation report, the retained actuary provides sound reasoning to support the City maintaining a contribution no less than 18.5%. 4�w Denton Firemen's Relief and Retirement Fund 19 Report of an Actuarial Audit SECTION E ACTUARIAL VALUATION RESULTS Actuarial Valuation Results Benefits At its core, the actuarial valuation and the resulting funding policy contribution must properly reflect the benefit structure of the retirement plan. We have reviewed both the Plan document and the retained actuary's benefit summary and compared these to the individual sample calculations provided to us. In general, the benefits promised by the Plan were reasonably incorporated in the actuarial valuation of the Plan. Actuarial Valuation Results As part of our review, GRS requested sample participant test life calculations from the retained actuary to ensure that the retained actuary valued the correct benefit levels, used the correct assumptions, and calculated the liabilities correctly on an individual basis. Generally accepted actuarial standards and practices provide actuaries with the basic mathematics and framework for calculating the actuarial results. When it comes to applying those actuarial standards to complex calculations, differences may exist due to individual opinion on the best way to make those complex calculations. This may lead to differences in the calculated results, but these differences should not be material. Active Participants. At the onset of the review, we requested that the retained actuary provide sample test life calculations for 10 active participants. The retained actuary provided the information we requested regarding the active participants with sufficient detail to allow for a thorough review of the calculations. Based on our review of the aspects of the actuarial valuation, the liability determination of active participants was reasonable and appropriately determined. Participants with deferred benefits. At the onset of the review, we requested that the retained actuary provide sample test life calculations for two deferred vested participants waiting to commence their retirement benefits, including two disabled deferred.The retained actuary provided the information we requested regarding these participants with deferred benefits with sufficient detail to allow for a thorough review of the calculations. Based on our review, the liability determination of these participants was reasonable and consistent with the stated assumptions and methods. Annuitants. At the onset of the review, we requested that the retained actuary provide sample test life calculations for 10 annuitants. The retained actuary provided the information we requested regarding the annuitants with sufficient detail to allow for a thorough review of the calculations. 4�w Denton Firemen's Relief and Retirement Fund 21 Report of an Actuarial Audit Based on our review, the liability determination of annuitants was reasonable and consistent with the stated assumptions and methods. Summary Besides the comments made in Section C of this report, we believe that the valuation results are developed in a reasonable manner. 4�w Denton Firemen's Relief and Retirement Fund 22 Report of an Actuarial Audit SECTION F CONTENT OF THE VALUATION REPORT Content of the Valuation Report ASOP No. 4, Measuring Pension Obligations and Determining Pension Plan Costs or Contributions, and ASOP No. 41,Actuarial Communications, provide guidance for measuring pension obligations and communicating the results. The Standards list specific elements to be included, either directly or by references to prior communication, in pension actuarial communications. The pertinent items that should be included in actuarial valuation report on a pension plan should include: A. The name of the person and/or firm retaining the actuary and the purposes that the communication is intended to serve. B. A statement as to the effective date of the calculations, the date as of which the participant and financial information were compiled, and the sources and adequacy of such information. C. An outline of the benefits being discussed or valued and of any significant benefits not included in the actuarial determinations. D. A summary of the participant information, separated into significant categories such as active, retired, and terminated with future benefits payable. Actuaries are encouraged to include a detailed display of the characteristics of each category and reconciliation with prior reported data. E. A description of the actuarial assumptions, cost method and the asset valuation method used. Changes in assumptions and methods from those used in previous communications should be stated and their effects noted. If the actuary expects that the long-term trend of costs resulting from the continued use of present assumptions and methods would result in a significantly increased or decreased cost basis, this should also be communicated. F. A summary of asset information and derivation of the actuarial value of assets. Actuaries are encouraged to include an asset summary by category of investment and reconciliation with prior reported assets showing total contributions, benefits, investment return, and any other reconciliation items. G. A statement of the findings, conclusions, or recommendations necessary to satisfy the purpose of the communication and a summary of the actuarial determinations upon which these are based. The communication should include applicable actuarial information regarding financial reporting. Actuaries are encouraged to include derivation of the items underlying these actuarial determinations. H. A disclosure of any facts which, if not disclosed, might reasonably be expected to lead to an incomplete understanding of the communication. Also, recently added to ASOP No. 4 is guidance for the actuary to calculate a Low-Default-Risk Obligation Measure ("LDROM"). This measurement is similar to the Actuarial Accrued Liability, but using a discount rate based on "low-default-risk fixed income securities whose cash flows are reasonably consistent with the pattern of benefits expected to be paid in the future."The retained actuary has included this measure in Appendix B. We believe the retained actuary used an appropriate discount rate and properly disclosed its source, satisfying this requirement in ASOP No.4. 4�v Denton Firemen's Relief and Retirement Fund 24 Report of an Actuarial Audit Regarding Items B. (outline of Plan benefits) and E. (describing assumptions and methods) above, we offer the following minor suggestions to the retained actuary to enhance completeness and clarity: • Include a disclosure of decrement timing • Include a disclosure of the timing of individual salary increases ASOP No. 51,Assessment and Disclosure of Risk Associated with Measuring Pension Obligations and Determining Pension Plan Contributions, supplements the guidance in the aforementioned ASOP Nos. 4, 27, 35, and 44. ASOP No. 51 provides several examples of methods to assess risk that may include, but are not limited to "scenario tests, sensitivity tests, stochastic modeling, stress tests, and a comparison of an actuarial present value using a discount rate derived from minimal-risk investments to a corresponding actuarial present value from the funding valuation". On page 3 of the valuation report the retained actuary provides scenarios of variation in the investment returns over the short term and the impact on the UAAL amortization period. Throughout the Valuation Summary discussion in Section 1 of the valuation report, the retained actuary provides additional language that satisfies ASOP No. 51. Section 3.7 of ASOP No. 51 provides guidance for the actuary to calculate and disclose plan maturity measures. Examples include: • the ratio of market value of assets to active participant payroll; • the ratio of retired life actuarial accrued liability to total actuarial accrued liability; • the ratio of a cash flow measure (such as benefit payments, or contributions less benefit payments) to market value of assets; • the ratio of benefit payments to contributions; and • the duration of the actuarial accrued liability. We recommend the retained actuary include in its report a historical table of some or all the measures above to help stakeholders identify risk trends overtime. Summary In general, the actuarial valuation report complied with the applicable Actuarial Standards of Practice. The presentation of actuarial methods and assumptions is generally complete and understandable. The methods described in this section are reasonable and appropriate for public retirement plans. We recommend the retained actuary clarify a few assumption details and expand its disclosure under the guidance of ASOP No 51, as noted above. 4�� Denton Firemen's Relief and Retirement Fund 25 Report of an Actuarial Audit SECTION G FINAL REMARKS Final Remarks The auditing actuarial firm, Gabriel, Roeder, Smith & Company (GRS), is independent of the DFRRF, the plan sponsor (the City), and retained actuarial firm. The auditing actuaries are not aware of any conflict of interest that would impair the objectivity of this work. We have presented a few suggestions for areas where we believe the product can be improved and we hope that DFRRF, the plan sponsor, and the retained actuary find these suggestions useful. The retained actuary has access to information and an extensive history of experience with DFRRF. We understand that the retained actuary may agree with some of our recommendations, while rejecting others. We ask that the retained actuary and DFRRF consider our recommendations carefully.

We received your May 16, 2025 preliminary report of the actuarial audit. The state law requiring actuarial audits of public employee pension plans gives the Fund Board of Trustees the opportunity to make written comments in response to your preliminary audit report. The Board has asked us to prepare the comments below on its behalf for inclusion in your final report to the City. We are pleased with the results of your actuarial audit. For the City of Denton and the Fund Board of Trustees, the key statement in your preliminary report is this sentence of the cover letter: "GRS is pleased to report to the City and DFRRF that, in our professional opinion, the December 31, 2023 Actuarial Valuation prepared by the retained actuary provides a fair and reasonable assessment of the financial position of the Plan." You made several recommendations in the Executive Summary, each of which is repeated below, with our response immediately following. Actuarial Experience Study "During the preparation of this actuarial audit, the retained actuary informed us that an actuarial experience study was planned for later this year. Had this not come to light, this would have been a primary recommendation. Thus, we recommend the retained actuary, the City, and the Fund carry out and complete this project as planned. More specifically, we recommend formal analyses of demographic assumptions, including but not limited to: retirement rates, termination rates, disability rates, individual salary increases, and mortality assumptions which include whether the more current Pub-2016 mortality tables and mortality improvement assumptions are more appropriate." 9500 Arboretum Blvd.,Suite 200 www.ruddwisdom.com Phone: (512)346-1590 Austin,Texas 78759 Fax: (512)345-7437 Mr. Thomas J. Bevins Page 2 June 13, 2025 We completed the actuarial experience study project for the Fund on May 30. It included analysis of all the demographic assumptions recommended above. In addition, we recommended the PubS-2016 mortality tables and the most recent mortality improvement projection scale (MP-2021) for the December 31, 2025 actuarial valuation. Compensation Increases "When preparing the actuarial experience study, we recommend the retained actuary consider extending the number of years for which Merit, Promotion, and Longevity increases apply (if supported by the Plan's experience)." In the actuarial experience study, we recommended assumed annual compensation increases for promotion, step, and longevity pay increases for the first 25 years of service. The prior assumption only assumed such increases for the first 15 years. Content of Valuation Report "Beyond the investment return scenarios on p. 3, we recommend the retained actuary expand its disclosures and risk metrics under the guidance of ASOP 51." "We recommend providing a reference to the origin of assumptions, whether it be to a formal experience study, published table, or acquired from prior actuary." "We recommend additional disclosures to the summary of Actuarial Methods and Assumptions (Exhibit 11) to include decrement timing and timing of individual salary increases." We are planning to implement these recommended additions to the Fund's biennial actuarial valuation reports beginning with the December 31, 2025 actuarial valuation. Please let us know if you have any questions about these responses. We appreciate the professional manner in which you have conducted this actuarial audit and your communications with Rudd and Wisdom. Sincerely, Mark R. Fenlaw, F.S.A. "64-�8. mamt� Rebecca B.
