Note: For cities without a 20-year/any age retirement provision, the rates for all ages under 45 are 0.000.<br />
For cities with fewer than 500 contributing members, the rates for all ages over 69 are 1.000.<br />
E. SERVICE RETIREE AND BENEFICIARY<br />
MORTALITY RATES<br />
1. For calculating the actuarial liability and the<br />
retirement contribution rates, the UP-1984 Table with<br />
an age set back of one year for males and an age set<br />
back of eight years for females.<br />
2. For determining the amount of the monthly<br />
retirement benefit at the time of retirement, the UP-<br />
1984 Table with an age set back of two years for retirees<br />
and an age set back of eight years for beneficiaries.<br />
F. DISABLED ANNUITANT MORTALITY RATES<br />
1. For calculating the actuarial liability and the<br />
retirement contribution rates, the 1983 Railroad<br />
Retirement Board Disabled Annuitants Mortality Table.<br />
2. For determining the amount of monthly retirement<br />
benefit at the time of retirement, the UP-1984<br />
Table with an age setback of two years for retirees and<br />
an age setback of eight years for beneficiaries.<br />
G. INTEREST RATE<br />
1. An annual rate of 7.0% for calculating the actuarial<br />
liability and the retirement contribution rates for<br />
the retirement plan of each participating city. Because<br />
of the money-purchase nature of the plans, the interest<br />
rate assumption does not have as significant an impact<br />
on the results of the actuarial valuation as it does for a<br />
defined benefit plan.<br />
2. An annual rate of 5.0% according to the <strong>TMRS</strong><br />
Act for (1) accumulating prior service credit and<br />
updated service credit after the valuation date, (2)<br />
determining the amount of the monthly benefit at<br />
future dates of retirement or disability, and (3) calculating<br />
the actuarial liability of the system-wide Current<br />
Service Annuity Reserve Fund and of the system-wide<br />
Supplemental Disability Benefits Fund.<br />
H. SALARY INCREASES<br />
Since no benefits earned to date are dependent<br />
upon future salaries, there is no need to make an<br />
assumption about future salary increases.<br />
I. PAYROLL INCREASE<br />
A payroll increase of 3%, 4%, or 5% per year as is<br />
considered appropriate for each individual city based<br />
primarily on experience during the periods 1993-1997<br />
and 1998-2002.<br />
J. VALUATION OF ASSETS<br />
<strong>TMRS</strong> continues to operate under a long-term, buy<br />
and hold philosophy, maintaining a predominantly<br />
bond portfolio (i.e.- no stock owned by the System at<br />
year-end). Neither a decline in nor rise in market<br />
value of the System’s <strong>fix</strong>ed-income portfolio is of material<br />
significance to its objectives. The actuarial value of<br />
assets is adjusted cost for bonds (original cost adjusted<br />
for amortization of premium or accrual of discount),<br />
cost for short-term securities, and cost for corporate<br />
stocks, which is the same as book value.<br />
K. SMALL CITY METHODOLOGY<br />
For cities with fewer than 3 employees, more conservative<br />
methods and assumptions are used. These<br />
effectively establish a lower limit for the normal cost<br />
rate and shorten the amortization period for the<br />
unfunded actuarial liability from 25 years to the average<br />
years remaining until normal retirement.<br />
