Administrative Factor Change Notification
The department of retirement systems uses administrative factors to calculate retirement benefits. Some of the ways factors are used include calculating the actuarial equivalent for early retirement and joint retirement options to provide approximately the same lifetime benefit as a normal single-life retirement. Optional costs are also based on factors when restoring withdrawn and optional service credit past the deadline, and when purchasing additional service or an annuity.
These administrative factors are periodically reviewed by the office of the state actuary (OSA). OSA recommends that the administrative factors be updated, if necessary, when the underlying demographic or economic assumptions change.
As a result of OSA's Demographic Experience Study for 2007-2012 and the phase-in of the lower investment rate of return, OSA has recommended revisions to the actuarial factors used by the department. The proposed actuarial factors are available for review at
There will be a thirty day review period and a public hearing to allow stakeholders to comment on the proposed factors. Comments may be submitted by e-mail to by 9 a.m., February 5, 2016, or in person at the hearing.
Hearing date, time and location: On February 5, 2016, 10 a.m., at the Department of Retirement Systems, 6835 Capitol Boulevard, Room 115, Tumwater, WA 98501.
The department anticipates adopting the proposed factors following the hearing on February 5, 2016. If adopted, the new rules will go into effect on October 1, 2016.
