Previous years' rates

FY18 Rates for the PERS/TRS Defined Benefit (DB) and Defined Contribution Retirement (DCR) Plans

** Please note the ARM Board has adopted the Fiscal Year 2018 actuarially determined contribution rates. The Division must review all legislation that impacts the retirement systems, and rates will be confirmed after legislative session is complete, and the review of retirement system legislation is completed. Notification of final rates will be posted at the end of June 2017, or as soon as the legislative session and the Division review is completed.

The Alaska Retirement Management Board (ARMB) has established Fiscal Year 2018 (FY18) employer contribution rates for the PERS/TRS Defined Benefit (DB) and Defined Contribution Retirement (DCR) Plans. The rates are effective for pay period end dates between July 1, 2017, and June 30, 2018.


FY18 Defined Benefit Plan Employer Contribution Rates

In setting the DB Plan rates, the ARMB addressed compliance with Senate Bill (SB) 125 [PDF], the PERS "cost-share" bill. In fiscal year 2008, the bill converted the PERS DB plan to a cost-share plan, like TRS, and provided for one integrated system of accounting for all employers. The bill established one uniform rate of 22 percent for PERS employers, rather than separate contribution rates for each employer. SB 125 amended AS 39.35.255 and repeals and reenacts AS 14.25.070:

  • AS 39.35.255 “Contributions by employers” establishes the uniform contribution rate for PERS employers at 22 percent, with the State contributing the difference between total PERS actuarially determined contributions and the amount employers contribute at 22 percent of payroll. (See AS 39.35.280 Additional State Contributions)
  • AS 14.25.070 “Contributions by employers” establishes the TRS employer contribution rate at 12.56 percent, with the State contributing the difference between total TRS actuarially determined contributions and the amount employers contribute at 12.56 percent of payroll. (See AS 14.25.085 Additional State Contributions)

The FY18 rates employers will pay (Employer Effective Rate) is 22 percent for PERS DB and DCR Plans; and 12.56 percent for TRS DB and DCR Plans.

The DB Plan employer rates for the PERS and TRS are outlined in the table below:

PERS/TRS DB Plan - FY 2018 Contribution Rates
(PERS Tiers I, II, III and TRS Tiers I, II)
  PERS (P)* and (A)* TRS
ARMB Adopted Rate 25.01% 26.78%
Employer Effective Rate 22.00% 12.56%
*P = Peace Officers / Firefighters
*A = All others

FY18 Defined Contribution Retirement Plan Employer Contribution Rates

There is no change in the DCR Plan computation for Fiscal Year 2018. The computation is the same, only the rates have changed. Senate Bill 123 [PDF], the "technical clean-up" bill, requires that the PERS and TRS DB rate be applied to both DB and DCR salaries. However, in some cases, the DB effective rate is not sufficient to cover all required DCR contributions. All DCR Plan employer contribution obligations are required. Employers will pay either the effective rate OR the DCR required rate plus the Health Reimbursement Arrangement (HRA), whichever amount is greater.

The DCR Plan employer rates for the PERS and TRS, are outlined in the tables below:

PERS/TRS DCR Plan - FY 2018 Contribution Rates
(PERS Tier IV and TRS Tier III)
PERS (P)* PERS (A)* TRS
Employer Contribution 5.00% 5.00% 7.00%
Retiree Medical Plan 1.03% 1.03% 0.91%
Occupational Death & Disability 0.43% 0.16% 0.00%
DCR Required Rate + HRA (= DCR Plan TOTAL contribution obligation) 6.46% + HRA** 6.19% + HRA** 7.91% + HRA**
Defined Benefit Unfunded Liability (DBUL) *** *** ***
Employer Effective Contribution Rate TOTALS 22.00% 22.00% 12.56%
*P = Peace officers/firefighters
*A = All others

**Per AS 39.30.370, a rate of 3.00% is applied to the average annual compensation of all employees of all employers in the TRS and PERS. The contribution amount is then converted to a per pay period, per employee contribution amount. Contributions to the employee's HRA account are required for every pay period in which the employee is enrolled in the DCR Plan, regardless of the compensation paid during the calendar year. By definition, the HRA cost is a dollar amount reflected in the table below:

FY 2018 HRA Amounts
Annual Quarterly Monthly Semi-monthly Bi-weekly Weekly
$2,084.16 $521.04 $173.68 $86.84 $80.16 $40.08

For full-time TRS members who are paid over a period of less than 12 months, the employer will calculate the amount due per pay period by dividing the annual amount by the number of scheduled payments. For example, for a full-time TRS member who receives:

  • 9 monthly payments the employer HRA monthly contribution would be $231.57 per pay period ($2,084.16 annual cost divided by nine payments).
  • 10 monthly payments the employer HRA monthly contribution would be $208.42 per pay period ($2,084.16 annual cost divided by ten payments).

For TRS part-time employees, the HRA rate is based on the contract percentage worked multiplied by the rate provided in the table above. For example, a 70% employee paid monthly would have a contribution to the HRA of $121.58 per pay period ($173.68 x 70%).

Note: For all school districts the prorated calculation of annual HRA contributions does not apply to PERS DCR Plan Noncertificated (classified) School Employees. These employees are NOT eligible to elect the alternate option program (SB9). Once the DRB PERS system is provided the Leave Without Pay (LWP) date for the last day worked for the school year, service is then turned off and HRA contributions are suspended for the summer break.

For part-time PERS members, the employer contributes the PERS hourly amount for each hour the employee worked in each pay period until the employer has contributed the annual amount for the fiscal year, illustrated in the table below:

FY 2018 HRA Amount
(PERS part-time members)
Hourly
$1.34

*** The Defined Benefit Unfunded Liability (DBUL) amount levied against the DCR Plan payroll is equal to the employer effective rate minus the DCR Plan total employer contributions. See the following PERS example below using occupation code "A" of semi-monthly payroll, where the gross payroll = $1,000.00:

DBUL Amount Example
Rates Employer amount
Employer contribution 5.00% $50.00
Retiree Medical Plan 1.03% 10.30
Occupational Death & Disability 0.16% 1.60
Health Reimbursement Arrangement (HRA) ** 86.84
Subtotal Employer contribution n/a $148.74
Employer Effective Rate (as required by SB 125) 22.00% 220.00
Subtotal from above (subtract from Effective Rate) n/a -148.74
Total Amount posted to DBUL n/a $71.26

Note: Testing showed that in some very rare cases, the amount calculated by eReporting for entry in DBUL may be less than zero (a negative number). In such cases, eReporting will post $0.00 as a DBUL contribution. In no case can the employer contribution to the DBUL be less than zero (a credit).
