February 24, 2017 Retirement Committee Dallas Area Rapid Transit 1401 Pacific Avenue Dallas, TX 75201 Re: DART Employees Defined Benefit Retirement Plan Dear Committee Members: We are pleased to present to the Committee this report of the annual actuarial valuation of the DART Employees Defined Benefit Retirement Plan. The valuation was performed to determine whether the assets and contributions are sufficient to provide the prescribed benefits and to develop the appropriate funding requirements for the applicable plan year. Please note that this valuation may not be applicable for any other purposes. The valuation has been conducted in accordance with generally accepted actuarial principles and practices, including the applicable Actuarial Standards of Practice as issued by the Actuarial Standards Committee, and reflects the financing objectives of the Employer, as well as applicable federal laws and regulations. In our opinion, the assumptions used in this valuation, as adopted by the Retirement Committee, represent reasonable expectations of anticipated plan experience. Future actuarial measurements may differ significantly from the current measurements presented in this report for a variety of reasons including: changes in applicable laws, changes in plan provisions, changes in assumptions, or plan experience differing from expectations. In conducting the valuation, we have relied on personnel, plan design, and asset information supplied by the DART faculty, financial reports prepared by the custodian bank, and the actuarial assumptions and methods described in the Actuarial Assumptions section of this report. While we cannot verify the accuracy of all this information, the supplied information was reviewed for consistency and reasonableness. As a result of this review, we have no reason to doubt the substantial accuracy of the information and believe that it has produced appropriate results. This information, along with any adjustments or modifications, is summarized in various sections of this report. 13420 Parker Commons Blvd., Suite 104 Fort Myers, FL 33912 (239) 433-5500 Fax (239) 481-0634 www.foster-foster.com

SUMMARY OF REPORT The annual actuarial valuation of the DART Employees Defined Benefit Retirement Plan, performed as of October 1, 2016, has been completed, and the results are presented in this Report. The contribution amounts developed in this valuation are applicable to the plan/fiscal year ended September 30, 2017. The contribution requirements, compared with amounts developed in the October 1, 2015 actuarial valuation report, are as follows: Valuation Date Applicable Plan/Fiscal Yr. End 10/1/2016 9/30/2017 10/1/2015 9/30/2016 Minimum Required Contribution ¹ (Payable on September 30) $7,754,873 $9,217,479 ¹ Reflects minimum required contribution payable at end of plan year. As can be seen, the Minimum Required Contribution has decreased by approximately $1.46 million since the previous valuation. There are three main sources that contributed to this decrease in the actuarial required contribution. The first source was due to an amortization charge base which was fully paid off in conjunction with the previous valuation. Additionally, there was net favorable actuarial experience during the year, on the basis of the actuarial assumptions. The primary components of favorable experience included an 8.10% investment return (Actuarial Asset Basis) which exceeded the 7.00% assumption, favorable retirement experience and a decrease in the Consumer Price Index which resulted in no cost of living adjustments being granted to retirees. These gains were partially offset by the effect of unfavorable inactive mortality. Finally, as the result of an actuarial experience study dated August 19, 2016, the Retirement Committee approved a number of changes to the actuarial assumption and methods, which contributed to a decrease in the actuarial required contribution. The specific changes are outlined on page 7 and the impact of these changes are displayed in the comparative summary section of this report.

CHANGES SINCE PRIOR VALUATION Plan Changes There have been no changes in benefits since the prior valuation. Actuarial Assumption/Method Changes In conjunction with an actuarial experience study dated August 19, 2016, the Retirement Committee approved a number of changes to the actuarial assumptions and methods, as outlined below: - The actuarial cost method was changed from the Projected Unit Credit to the Entry Age Normal actuarial cost method. - The outdated funding method of developing the minimum required contribution as if the plan were subject to Section 412 of the Internal Revenue Code of 1986 was removed. Beginning with this valuation, the minimum required contribution will be developed to be consistent with the methodology utilized for other public pension plans. - The assumed rate of investment return was lowered from 7.00% to 6.75% per year, net of all expenses. - The salary increase assumption was lowered from 3.25% to 3.00% per year until the assumed retirement age. - The assumed rates of mortality were amended to remove incorporating fully generational mortality improvements and implement projecting mortality improvements to the valuation date. - The assumed rates of retirement were amended at certain ages. - The assumed rates of termination were amended at certain ages and to eliminate varying rates by gender. - The assumed rates of disablement were reduced in half.

ACTUARIAL ASSUMPTIONS AND METHODS Mortality Rate Healthy Lives: RP-2000 Combined Healthy Table (sex distinct) with rates increased by 8.59% and with mortality improvement projections to the valuation date (previously fully generational) using Scale AA. Disabled Lives: RP-2000 Disabled Mortality Table (sex distinct). The assumed rates of mortality are reasonable as they sufficiently accommodate expected future mortality improvements. The rates were approved in conjunction with an actuarial experience study performed in 2016. Interest Rate Retirement Age 6.75% (previously 7.00%) per year compounded annually, net of all expenses. This is supported by the target asset allocation of the trust and the expected long-term return by asset class.

The assumed rate of salary increase was approved in conjunction with an actuarial experience study performed in 2016. None. Dallas Area Rapid Transit Employees' Defined Benefit Retirement Plan FOSTER & FOSTER 14

Inflation Valuation Compensation 2.50% per year. This is reasonable based on long-term historical increases. Future compensation utilized for valuation purposes is developed as the sum of: 1) Base pay (projected with salary increases) 2) Bonus pay (projected with salary increases) 3) Service-Incentive pay (projected assuming payment of $6 per month of service (maximum of $150 per month) Termination Rate 1.50% per year prior to age 54, and 1.00% per year on and after attainment of age 54. Previously, members were assumed to terminate employment at varying rates based on age and gender. These rates were approved in conjunction with an actuarial experience study performed in 2016. Disability Rate Members are assumed to become disabled prior to retirement at varying rates based on age. Sample rates are as follows: Age Current Rate Previous Rate 45 0.06% 0.12% 50 0.12 0.24 55 0.21 0.42 60 0.30 0.60 These rates were approved in conjunction with an actuarial experience study performed in 2016. Marital Status Actuarial Cost Method Actuarial Asset Method 85% of male participants and 65% of female participants are assumed to be married. Additionally, male spouses are assumed to be three years older than female spouses. Entry Age Normal (previously Projected Unit Credit) Actuarial Cost Method. All assets are valued at market value with an adjustment made to uniformly spread actuarial investment gains and losses (as measured by actual market value investment return against expected market value investment return) over a fiveyear period. Dallas Area Rapid Transit Employees' Defined Benefit Retirement Plan FOSTER & FOSTER 15

VALUATION NOTES Total Annual Payroll is the annual rate of valuation compensation as of the valuation date of all covered Members. Payroll Under Assumed Retirement Age is the annual rate of valuation compensation for all Members who are not subject to a 100% probability of retirement as of the valuation date. Present Value of Benefits is the single sum value on the valuation date of all future benefits to be paid to current Members, Retirees, Beneficiaries, Disability Retirees and Vested Terminations. Normal (Current Year's) Cost is determined for each participant as the present value of future benefits, determined as of the member s entry age, amortized as a level percentage of compensation over the anticipated number of years of participation, determined as of the entry age. Individual Entry Age Normal Actuarial Cost Method (Level Percent of Compensation) is the method used to determine required contributions under the Plan. The use of this method involves the systematic funding of the Normal Cost (described above) and the Unfunded Accrued (Past Service) Liability. The actuarial accrued liability for active participants is the difference between the present value of future benefits and the present value of future Normal Costs. The actuarial accrued liability for inactive participants is the present value of future benefits. Unfunded Actuarial Accrued Liability (UAAL) is the difference between the actuarial accrued liability (described above) and the actuarial value of assets. Under the Entry Age Normal Actuarial Cost Method, an actuarial gain or loss, based on actual versus expected UAAL, is determined in conjunction with each valuation of the plan.
