The actuarial assumptions were developed primarily from the actuarial investigation of the experience<br />

of TMRS over the four-year period from December 31, 2014 to December 31, 2018. They were adopted<br />

in 2019 and first used in the December 31, 2019 actuarial valuation. The post-retirement mortality<br />

assumption for Annuity Purchase Rates (APRs) is based on the Mortality Experience Investigation Study<br />

covering 2009 through 2011 and dated December 31, 2013. Plan assets are managed on a total return<br />

basis with an emphasis on both capital appreciation as well as the production of income in order to<br />

satisfy the short-term and long-term funding needs of TMRS.<br />

The long-term expected rate of return on pension plan investments was determined using a buildingblock<br />

method in which best estimate ranges of expected future real rates of return (expected returns,<br />

net of pension plan investment expenses and inflation) are developed for each major asset class. These<br />

ranges are combined to produce the long-term expected rate of return by weighting the expected future<br />

real rates of return by the target asset allocation percentage and by adding expected inflation. In<br />

determining their best estimate of a recommended investment return assumption under the various<br />

alternative asset allocation portfolios, GRS focused on the area between (1) arithmetic mean<br />

(aggressive) without an adjustment for time (conservative) and (2) the geometric mean (conservative)<br />

with an adjustment for time (aggressive). The target allocation and best estimates of arithmetic real<br />

rates return for each major asset class in fiscal year <strong>2021</strong> are summarized in the following table:<br />

Long-Term Expected<br />

Real Rate of Return<br />

Asset Class Target Allocation (Arithmetic)<br />

Global Equity 30.00% 5.30%<br />

Core fixed income 10.00% 1.25%<br />

Non-core fixed income 20.00% 4.14%<br />

Real return 10.00% 3.85%<br />

Real estate 10.00% 4.00%<br />

Absolute return 10.00% 3.48%<br />

Private equity 10.00% 7.75%<br />

Total 100.00%<br />

Discount Rate<br />

The discount rate used to measure the Total Pension Liability was 6.75%. The projection of cash flows<br />

used to determine the discount rate assumed that employee and employer contributions will be made<br />

at the rates specified in statute. Based on that assumption, the pension plan’s Fiduciary Net Position<br />

was projected to be available to make all projected future benefit payments of current active and inactive<br />

employees. Therefore, the long-term expected rate of return on pension plan investments was applied<br />

to all periods of projected benefit payments to determine the Total Pension Liability.<br />
