Pension Plans Summary

TMRS Summary

The funded status represents the ratio of a pension’s assets to its liabilities or obligations. A funded status of 100% means that an entity has exactly enough assets set aside to pay for its future pension obligations at that particular point in time. TMRS employs two separate actuarial valuations under which the funded status is measured – the funding valuation and the Governmental Accounting Standards Board (GASB) 68 valuation. The primary difference between the two calculations is that the assets for purposes of the funding valuation are “smoothed” to lessen the volatility of market fluctuations of investments while the GASB 68 valuation captures the asset market value of a particular moment in time. Over time, the City is working towards a funded status of 100%. As of December 31, 2016, the City is funded as follows as it relates to the TMRS plan:

Funded ratio (Funding Valuation)  87.9%
Funded ratio (GASB 68 Valuation)   86.2%
Amortization Period  17.1 years
Unfunded Amount as a percentage of Covered Payroll 93.37%

Actuarial gains or losses (which arise from changes in actuarial assumptions) are amortized over an 18 year period.

Rate of Return

 The rate of return (discount rate) factors heavily into the calculation of the actuarial accrued pension liability. If TMRS does not earn its projected rate of return, assets will be less than expected and the City will have to make additional contributions to fund the shortfall.

Comparison of Actuarially Determined Contributions to Actual Contributions

TMRS Employer Contributions as Percent of Payroll Compared to TMRS Required Contribution

The TMRS actuary develops an Actuarially Determined Contribution rate through the annual valuation process for each city. As required by state statute, each City is legally obligated to contribute at least the Actuarially Determined Contribution which is synonymous with the TMRS Required Minimum Contribution Rate. As you can see from the charts, the City of Plano not only made the TMRS Required Minimum Contribution Rate, but in the past three years, the City has contributed in excess of these contributions as this eliminates future interest costs, improves funding percentages, and provides a cushion of protection for budgetary purposes against rate volatility.

Please note that due to changes in actuarial assumptions, TMRS allowed cities that experienced more than a 0.5% increase to phase in the increase over an 8-year period, which is why the City contributed less than the full rate in 2012 and 2013.

Actuarial Value of Assets vs. Liabilities and Funded Ratio

TMRS Actuarial Accrued Liability, Actuarial Value of Assets and Funded Ratio

The Actuarial Accrued Liability represents the present value of the obligation of the pension to its members whereas the Actuarial Value of Assets represents the funds in trust set aside to meet that obligation. The difference in these values represents the Unfunded Actuarial Accrued Liability and the ratio of assets to liabilities determines the plan’s Funded Ratio.

As denoted from the information above, both the City’s assets and liabilities continue to grow as there is corresponding growth with additional members, however, the City has also demonstrated a continual improvement in its funded ratio over time as it moves towards a fully funded status.

Retirement Security Plan (RSP) Summary

The funded status represents the ratio of a pension’s assets to its liabilities or obligations. A funded status of 100% means that an entity has exactly enough assets set aside to pay for its future pension obligations at that particular point in time. The City receives two separate actuarial valuations for the Retirement Security Plan under which the funded status is measured – the funding valuation and the Governmental Accounting Standards Board (GASB) 68 valuation. The primary difference between the two calculations is that the assets for purposes of the funding valuation are “smoothed” to lessen the volatility of market fluctuations of investments while the GASB 68 valuation captures the asset market value of a particular moment in time. The City’s funded is near 100% and fluctuates both above and below that status due to volatility in the assets of the plan. As of December 31, 2015 the RSP is funded as follows:

Funded ratio (Funding Valuation)  99.2%
Funded ratio (GASB 68 Valuation)  98.32%
Amortization Period  19 years
Unfunded Amount as a Percentage of Covered Payroll 0.7%

Actuarial gains or losses (which arise from changes in actuarial assumptions) are amortized over an 18 year period.

Rate of Return

The rate of return (discount rate) factors heavily into the calculation of the actuarial accrued pension liability. If the City does not earn its projected rate of return, assets will be less than expected and the City will have to make additional contributions to fund the shortfall.

Comparison of Actuarially Determined Contributions to Actual Contributions

The City’s actuarial firm develops an Actuarially Determined Contribution rate through the biennial valuation process. The City’s actual contributions have equaled the Actuarially Determined Contributions each year. As the City is near 100% funded, the City has only contributed the Actuarially Determined Contribution as compared to TMRS where the City has made contributions in excess of the Actuarially Determined Rate.

The Actuarial Accrued Liability represents the present value of the obligation of the pension to its members whereas the Actuarial Value of Assets represents the funds in trust set aside to meet that obligation. The difference in these values represents the Unfunded Actuarial Accrued Liability and the ratio of assets to liabilities determines the plan’s Funded Ratio.

As denoted from the information above, the City’s funded ratio hovers around 100% as it is primarily impacted by the fluctuation in the market value of the investments.
