Oregon Revised Statutes Public Officers and Employees § 238.270

Whenever a person who is past the earliest service retirement age separates from the service of a public employer participating in the Public Employees Retirement System and who thereafter, but before applying to the Public Employees Retirement Board for retirement benefits, is employed in a position that entitles the person to membership in another public employees retirement system, either within or without this state, the board, upon the written request of the person and if in conformance with the provisions of law governing the other public employees retirement system, may transfer the member account, if any, of the person in the fund to the other public employees retirement system. Such transfer shall cancel the right of the person to claim any future benefits under the Public Employees Retirement System for service rendered to a public employer in this state prior to the date of the transfer.
