Washington Revised Code Title 41. Public Employment, Civil Service, and Pensions § 41.50.730. Retirement or termination agreement payments--Effect on pension benefits calculation

(1) If the agreement does not require the employee to perform additional service, the payment shall not be used in any way to calculate the pension benefit.

(2) If the agreement requires additional service and results in payment at the same or a lower rate than that paid for the same or similar service by other employees it may be included in the pension benefit calculation but shall be deemed excess compensation and is billable to the employer as provided in RCW 41.50.150.

(3) If the agreement requires additional service and results in payment at a rate higher than that paid for the same or similar service by other employees, that portion of the payment which equals the payment for the same or similar service shall be treated as described in subsection (2) of this section, and the balance of the payment shall be treated as described in subsection (1) of this section.
