FY10 Employer Contribution Rates

Previous years' rates

PERS/TRS Defined Benefit (DB) and Defined Contribution Retirement (DCR) Plans

The Alaska Retirement Management Board (ARMB) has established Fiscal Year 2010 (FY10) 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, 2009, and June 30, 2010.

FY10 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 amends 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 actuarial required contributions and the amount employers contribute at 22 percent of payroll.
  • 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 actuarial required contributions and the amount employers contribute at 12.56 percent of payroll.

The FY10 rates employers will actually pay (Employer Effective Rate) were set at 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 2010 Contribution Rates
(PERS Tiers I, II, III and TRS Tiers I, II)
PERS (P)* and (A)* TRS
*P = Peace officers/firefighters
*A = All others
ARMB Adopted Rate 27.65% 39.53%
Employer Effective Rate 22.00% 12.56%

FY10 Defined Contribution Retirement Plan Employer Contribution Rates

There is no change in the DCR Plan computation for Fiscal Year 2010. 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 will not be 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, and the HRA amounts, are outlined in the tables below:

PERS/TRS DCR Plan - FY 2010 Contribution Rates
*P = Peace officers/firefighters
*A = All others
Employer Contribution 5.00% 5.00% 7.00%
Retiree Medical 0.83% 0.83% 1.03%
Occupational Death & Disability 1.33% 0.30% 0.32%
DCR Required Rate + HRA = DCR Plan TOTAL contribution obligation 7.16% + HRA** 6.13% + HRA** 8.35% + HRA**
Defined Benefit Unfunded Liability (DBUL) *** *** ***
Employer Effective Contribution Rate TOTALS 22.00% 22.00% 12.56%

**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 2010 HRA Amounts
Annual Quarterly Semi-monthly Bi-weekly Monthly
$1,699.71 $424.93 $70.82 $65.37 $141.64

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 nine monthly payments the employer contribution would be $188.86 per pay period ($1,699.71 annual cost divided by nine payments).

For all school districts, please note, 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 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 $99.15 per pay period ($141.64 x 70%).

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 2010 HRA Amount
(PERS part-time members)

*** 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. Please examine the following PERS Example of semi-monthly payroll, where the gross payroll = $1000.00:

DBUL Amount Example
Rates Employer amount
Employer contribution 5.00% $50.00
Retiree Medical Plan 0.83% 8.30
Occupational Death & Disability 0.30% 3.00
Health Reimbursement Arrangement (HRA) ** 70.82
Subtotal Employer contribution n/a $132.12
Employer Effective Rate (as required by SB 125) 22.00% 220.00
Subtotal from above (subtract from Effective Rate) n/a -132.12
Total Amount posted to DBUL n/a $87.88

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).

FY10 Allocation of Pension and Other Post Employment Benefits (OPEB)

For purposes of reporting and posting, the allocation between Pension and other Post Employment Benefits (referred to as Healthcare by the Division) is applied to each payroll upon processing by the Division. The tables below provide the rates used to allocate all employer contributions between Pension and Healthcare.

Below is the allocation for DB PERS and TRS Pension and Healthcare

All other occupation codes (A, C, D, E, F, M & P)
