80 Ill. Adm. Code 1600.260
Part-time/Concurrent Service Adjustment
Section 1600.260 Â Part-time/Concurrent Service Adjustment
This Section will clarify how the
percentage of time
employed for each year of employment
is determined for the service
adjustment under Section 15-134.1(b) of the Code. This percentage cannot
exceed 100%.
The service adjustment under Section
15-134.1(b) of the Code
shall not apply to a member who is a participant on
or after September 1, 2024
.
a)Â Â Â Â Â Â Â Â Determine the average
monthly percent time worked.
1)Â Â Â Â Â Â Â Â Establish
the monthly full-time equivalent (FTE) earnings for each employer by dividing the
monthly earnings from that employer by the percent time the participant worked
for that employer for that month.
2)Â Â Â Â Â Â Â Â Total
the participant's earnings from all employers for that month and divide by the
highest full-time equivalent.
3)Â Â Â Â Â Â Â Â This
results in the average monthly percent time worked.
4)Â Â Â Â Â Â Â Â Example:

Average monthly
percent time worked = 79.6% ($995 divided by $1,250)
b)Â Â Â Â Â Â Â Â Determine
the percentage of time employed for each relevant year of employment.
1)Â Â Â Â Â Â Â Â Total
the average monthly percent time worked for each month in the academic year for
which the participant had earnings.
2)Â Â Â Â Â Â Â Â Divide
this number by the total number of months during the academic year for which
the participant had earnings.
3)Â Â Â Â Â Â Â Â This
calculation results in the percentage of time employed for each year of
employment.

Percentage of time employed for the
year of employment is 54.5% (436.0 divided by 8).
c)Â Â Â Â Â Â Â Â Calculate
Annuity
1)Â Â Â Â Â Â Â Â In calculating
a retirement annuity, if the participant's "percentage of time employed
for each year of employment is 50% or less for 3 or more years after September
1, 1959, service is granted for employment in excess of 3 years", in the
proportion that the percentage of time employed for each year of employment
bears to the average annual percentage of time employed during the period on
which the final rate of earnings is based. An example calculation for this
subsection (c) is:

2)Â Â Â Â Â Â Â Â In
this example, the final rate of earnings are based on years 6 through 9. The
average annual percentage of time employed during the period on which the final
rate of earnings is based is 57.5%. This is the sum of years 6 through 9
percentages divided by 4.
3)Â Â Â Â Â Â Â Â Years
1 through 6 have percentages of 50% or less and must be tested for adjustment.Â
The participant receives 3 of these years without adjustment. To maximize the
service that is used in the calculation of the retirement annuity, those years
with the smallest percentages will be applied to the 3 years the participant
receives without adjustment. In this example, that is years 1 through 3.Â
Therefore, only years 4 through 6 require adjustment. To determine the
adjusted service, divide the "percentage of time employed" by the
"average annual percentage of time employed during the period on which the
final rate of earnings is based", then multiply by the unadjusted
service. If year 4's unadjusted service had been 0.50 year, the adjusted
service would have been 30%/57.5% x 0.50 = .2609.
d)Â Â Â Â Â Â Â Â The
service credit adjustment in subsection (c) is not made in determining the
participant's eligibility for a retirement annuity, disability benefits,
additional death benefits, or survivors' insurance.
