Oregon Revised Statutes Public Officers and Employees § 238A.360

(1) The Public Employees Retirement Board may accept rollover contributions from a member of the individual account program or from an eligible retirement plan from which the member is entitled to an eligible rollover distribution. The board may accept rollover contributions under this section only if the amounts contributed qualify as eligible rollover distributions under the federal income tax laws governing tax-qualified retirement plans and, if the rollover contribution is made by the member, the contribution is paid to the individual account program within the time limits established by the federal income tax laws governing tax-qualified retirement plans.

(2) The board shall adopt rules and establish procedures for determining whether to accept a rollover contribution under this section and shall require such documentation as may be necessary to ensure that the receipt of a rollover contribution does not jeopardize the status of the individual account program as a tax-qualified governmental plan.
