1 TRS and SERS rates are effective from 9/1 to 8/31 of each year.  Employer rates exclude the administrative expense rate collected by the Department of Retirement Systems.
2 There is a 50% chance contribution rates will be between optimistic and pessimistic. There is a 25% chance contribution rates will be higher than pessimistic and a 25%  chance contribution rates will be lower than optimistic.
Rates shown for 2015-17 are projections based on the 2012 Actuarial Valuation. The LEOFF Plan 2 rates were adopted by the LEOFF Plan 2 Retirement Board and will be in effect through 2017. Therefore, we do not expect those rates to be different under optimistic and pessimistic scenarios. Please see the Projection Disclosures page for projection assumptions not disclosed in the valuation report.
4 Plan 1 members' contribution rate is statutorily set at 6.0%.  Members in Plan 3 do not make contributions to their defined benefit.
5 In the LEOFF plans only, the state pays a percent of the total cost of benefits.
