RCW 41.45.062 Annual contribution rate increases — Employer, state, and plan 2 members.

The basic employer and state contribution rates and required plan 2 member contribution rates are changed to reflect the 2003 actuarial valuation and actuarial projections of the 2005 actuarial valuation, both of which incorporate the 2002 actuarial experience study conducted by the office of the state actuary for 1995-2000. This contribution rate schedule departs from the normal biennial process for setting contribution rates by requiring annual increases in rates during the 2005-2007 biennium, and by requiring annual rates to be adopted by the pension funding council for the 2007-2009 biennium. The rates are lower in the 2005-2007 biennium than required by the 2003 actuarial valuation and will be higher in the 2007-2009 biennium than required by the projected 2005 actuarial valuation. Upon completion of the 2005 actuarial valuation, the pension funding council and the state actuary shall review the appropriateness of the contribution rates for 2007-2008 and 2008-2009 and by September 30, 2006, the pension funding council shall adopt contribution rates to complete the four-year phase-in schedule, adjusted for any material changes in benefits or actuarial assumptions, methods, or experience. This contribution rate schedule also requires a departure from the allocation formula for contributions in RCW 41.45.050 , suspension of payments on the unfunded liability in the public employees' retirement system and the teachers' retirement system during the 2005-2007 biennium, and a delay in the recognition of the cost of future gain-sharing benefits until the 2007-2009 biennium. (1) Beginning July 1, 2005, the following employer contribution rate shall be charged: 2.25 percent for the public employees' retirement system. (2) Beginning September 1, 2005, the following employer contribution rates shall be charged: (a) 2.75 percent for the school employees' retirement system; and (b) 2.73 percent for the teachers' retirement system. (3) Beginning July 1, 2005, the following member contribution rate shall be charged: 2.25 percent for the public employees' retirement system plan 2. (4) Beginning September 1, 2005, the following member contribution rates shall be charged: (a) 2.75 percent for the school employees' retirement system plan 2; and (b) 2.48 percent for the teachers' retirement system plan 2. (5) The contribution rates in subsections (1) through (4) of this section shall be collected through June 30, 2006, for the public employees' retirement system, and August 31, 2006, for the school employees' retirement system and the teachers' retirement system. (6) Beginning July 1, 2006, the following employer contribution rate shall be charged: 3.50 percent for the public employees' retirement system. (7) Beginning September 1, 2006, the following employer contribution rates shall be charged: (a) 3.75 percent for the school employees' retirement system; and (b) 3.25 percent for the teachers' retirement system. (8) Beginning July 1, 2006, the following member contribution rate shall be charged: 3.50 percent for the public employees' retirement system plan 2. (9) Beginning September 1, 2006, the following member contribution rates shall be charged: (a) 3.75 percent for the school employees' retirement system plan 2; and (b) 3.00 percent for the teachers' retirement system plan 2. (10) During the 2005 interim, the select committee on pension policy shall study the options available to the legislature for addressing the liability associated with future gain-sharing benefits. These options may include, but shall not be limited to, repealing, delaying, or suspending the gain-sharing provisions in law; making gain-sharing discretionary; or replacing gain-sharing benefits with other benefits such as plan choice, employer defined contributions, retirement eligibility enhancements, and postretirement adjustments. The select committee on pension policy shall report the findings and recommendations of its study to the legislative fiscal committees by no later than December 15, 2005.

RCW 41.45.0631 Washington state patrol retirement system — Contribution rates — Allocation of costs.

(1) The allocation of costs between the employer and members of the Washington state patrol retirement system shall be made only after the application of any minimum total contribution rate that may be in effect for the system under subsection (4) of this section. For benefit improvements effective on or after July 1, 2007, costs shall be shared equally by members and the employer, and any cap on member contributions shall be adjusted accordingly. The member contribution rate shall be based on the adjusted total contribution rate described in subsection (2) of this section. Beginning July 1, 2007, the required member contribution rate for members of the Washington state patrol retirement system shall be the lesser of the following: (a) One-half of the adjusted total contribution rate for the system; or (b) seven percent, plus fifty percent of the contribution rate increase caused by any benefit improvements effective on or after July 1, 2007. (2) The employer shall continue to pay for all costs attributable to distributions under RCW 43.43.270 (2) for survivors of members who became disabled under RCW 43.43.040 (2) prior to July 1, 2006, until such costs are fully paid. In order to avoid charging members for these costs, the total required contribution rate shall be adjusted to exclude these costs. The result of the adjustment shall be the adjusted total contribution rate that is to be used to calculate the required member contribution rate. (3) The employer rate shall be the contribution rate required to cover all total system costs that are not covered by the member contribution rate. (4) Beginning July 1, 2009, a minimum total contribution rate is established for the Washington state patrol retirement system. The total Washington state patrol retirement system contribution rate may exceed, but may not drop below, the established minimum total contribution rate. From July 1, 2009, through June 30, 2011, the minimum total contribution rate shall equal the total contribution rate required to fund fifty percent of the Washington state patrol retirement system's normal cost as calculated under the entry age normal cost method. Beginning July 1, 2011, the minimum total contribution rate shall equal the total contribution rate required to fund seventy percent of the Washington state patrol retirement system's normal cost as calculated under the entry age normal cost method. This minimum rate, when applicable, shall be collected in addition to any contribution rate required to amortize any unfunded costs attributable to distributions under RCW 43.43.270 (2) for survivors of members who became disabled under RCW 43.43.040 (2) prior to July 1, 2006. (5) Upon completion of each biennial actuarial valuation, the state actuary shall review the appropriateness of this minimum total contribution rate and recommend to the council any adjustments as may be needed. Any changes adopted by the council shall be subject to revision by the legislature. (6) The legislature recognizes the short-term volatility of projected employer contribution rates for the Washington state patrol retirement system and intends to phase-in the increase in contribution rates from the 2017-2019 biennium to the 2019-2021 biennium over three successive biennia.

Consistent with this intent, the legislature revises the basic employer contribution rate for the Washington state patrol retirement system from 22.13 percent to 17.5 percent during the 2019-2021 biennium. By June 30, 2020, the state actuary shall calculate and report to the council the expected change to the basic employer contribution rates for the 2021-2023 and 2023-2025 biennia that continue this phase-in.
