Background: The Pension Funding Council (PFC) was created by the Legislature in 1998 to adopt the long-term economic assumptions and employer contribution rates for most state retirement systems. The PFC membership consists of the chair and ranking minority members of the Senate Ways and Means Committee and the House Appropriations Committee, and the directors of the Office of Financial Management and the Department of Retirement Services (DRS).

The Office of the State Actuary (State Actuary) is responsible for recommending appropriate member and employer contribution rates for the Public Employees', Teachers', School Employees', and Washington State Patrol Retirement Systems as well as the Law Enforcement Officers' and Fire Fighters' Retirement System (LEOFF) Plan 1 to the PFC. The PFC must adopt the pension contribution rates for the upcoming fiscal biennium no later than July 31 of even-numbered years.

The employer contribution rates adopted by the PFC for each of the retirement systems, referred to as the basic employer contributions rates, are adopted consistent with the overall results of the actuarial valuation results provided by the State Actuary. Basic employer contribution rates are calculated by the State Actuary for each system or plan and are charged as an equal percent of member-covered salaries for all employers in the retirement plan. In addition to the basic employer contribution rates, many of the retirement systems also include employer contribution rates to amortize the unfunded accrued actuarial liability, often referred to as simply the unfunded liability, in the Public Employees' Retirement System (PERS) Plan 1 and the Teachers' Retirement System (TRS) Plan 1.

DRS was created in 1976 to administer the retirement systems for state and local government employees in Washington. These retirement systems include PERS; TRS; the School Employees' Retirement System; LEOFF; the Washington State Patrol Retirement System; and the Public Safety Employees' Retirement System.

DRS requires employers to determine the state retirement plan membership and employer and member contributions due for their employees. For each state retirement plan member, the employer must calculate those contribution amounts, report the amounts due to DRS, and then submit payment to DRS by the 15th of the month following the close of a reporting period. Payments received more than three business days after the 15th of the month are considered late and may be subject to interest at a rate of 1 percent per month on the outstanding balance.

In the event that member or employer contributions are made other than immediately after service is rendered, DRS may also charge interest as determined by the Director of DRS on member or employer contributions owed to the state retirement plan. This DRS authority was enacted by the Legislature in 1994 with a finding that when contributions are not made at the time service is rendered, the state retirement system trust funds lose investment income, which is a major source of pension funding.
