(b) The percentage increase provided for in this section shall be adjusted by the board to reflect increases or decreases in a member’s retirement allowance that are attributable to the member’s participation in the Variable Annuity Account established by ORS 238.260, that are attributable to a change in the member’s beneficiary or payment option under ORS 238.305 or 238.325, or that are attributable to corrections to the member’s retirement allowance calculation.
(c) The percentage increase provided for in this section shall be applied to any lump sum payment made to a member or a beneficiary of a member on or after January 1, 1991, that is attributable to a retroactive correction or adjustment of the amount payable to the member or beneficiary as a retirement allowance or that is attributable to a retroactive correction or adjustment to any other benefit that entitles a member or beneficiary to an increased benefit under this section. The percentage increase payable under this paragraph applies only to the principal amounts included in the lump sum payment as a retroactive correction or adjustment and does not apply to any interest on the retroactive correction or adjustment paid as part of the lump sum payment.
(2) The amount of any death benefit under ORS 238.390, 238.395, 238.400 or 238.405, including the amount of any monthly payments, shall be increased by the greater of the percentage provided for in ORS 238.366 or the percentage calculated under subsection (4) of this section.
(3)(a) A member of the system who elects to receive a lump sum in lieu of a retirement allowance or other benefit under ORS 238.315 shall receive an increase based on the greater of the percentage provided for in ORS 238.366 or the percentage calculated under subsection (4) of this section.
(b) A member of the system who withdraws the amount credited to the member account, if any, of the member in the fund under the provisions of ORS 238.265, or whose member account is returned to the employee after the membership of the employee is terminated under the provisions of ORS 238.095, shall receive an additional amount calculated by multiplying the amount of the member account of the member by the greater of the percentage provided for in ORS 238.366 or the percentage calculated under subsection (4) of this section. If a member thereafter elects to obtain restoration of creditable service by repaying the amount of the withdrawn member account pursuant to the provisions of ORS 238.105, the member must also repay all amounts paid under this section, together with interest from the date of withdrawal at the same rate as applied to the withdrawn member account under ORS 238.105. If a member repays only part of the withdrawn member account pursuant to the provisions of ORS 238.115, the member must repay that part of the amount paid under this section that is proportionate to the portion of the withdrawn member account that is repaid under ORS 238.115, together with interest from the date of withdrawal at the same rate as applied to the withdrawn member account under ORS 238.115. All amounts paid to the member that are subsequently repaid under ORS 238.105 or 238.115 shall be deposited by the board to the employer reserve for pension accounts in the fund.
(4)(a) The Public Employees Retirement Board shall calculate a multiplier for the purposes of this section equal to the percentage produced by the following formula:
1
________
.91
(b) Upon the retirement or death of a member of the system, the board shall determine the fraction of the member’s retirement allowance or death benefit, including any refund or lump sum payment, that is attributable to service rendered by the member before October 1, 1991. The board shall then calculate a percentage that is equal to that fraction multiplied by the multiplier determined by the board under paragraph (a) of this subsection. The percentage so calculated shall be used to determine the amount of the increase in benefits provided to a member, if any, under this section.
(5) For the purpose of determining that portion of a retirement allowance or death benefit attributable to service rendered before October 1, 1991, the board shall divide the number of years of creditable service performed before October 1, 1991, by the total number of years of creditable service during which the pension income was earned. For the purposes of this subsection:
(a) The number of years of creditable service does not include any period of employment for which a benefit is paid for prior service credit.
(b) Except as provided in subsection (7) of this section, the number of years of creditable service includes all retirement credit of the member, and any retirement credit of a member that is attributable to periods of service, employment or other activity performed before October 1, 1991, shall be considered creditable service performed before October 1, 1991.
(6) The increased benefits provided for in this section shall be funded by employer contributions.
(7) The increased benefits provided by this section apply only to members who establish membership in the Public Employees Retirement System before July 14, 1995, and whose effective date of retirement or date of death is on or after January 1, 1991. The increased benefits provided by this section do not apply to any creditable service or prior service credit acquired by a member under the terms of a contract of integration entered into pursuant to ORS 238.035, 238.680 or 238.690 on or after October 1, 1991.
(8) If a member is entitled to receive an increased benefit under the provisions of this section, and any portion of the member’s retirement allowance or other benefit payable under the system is payable to an alternate payee under the provisions of ORS 238.465, the increased benefits payable under this section shall be divided between the member and the alternate payee in proportion to the share of the total benefit received by each person. If an alternate payee elects to begin receiving benefits under ORS 238.465 (1) before the member’s effective date of retirement, the alternate payee may not begin receiving the increased benefit provided for in this section until benefits are first paid from the system on behalf of the member.
(9) A person establishes membership in the system before July 14, 1995, for the purposes of subsection (7) of this section if:
(a) The person is a member of the system, or a judge member of the system, on July 14, 1995;
(b) The person was a member of the system before July 14, 1995, ceased to be a member of the system under the provisions of ORS 238.095, 238.265 or 238.545 before July 14, 1995, but restores part or all of the forfeited creditable service from before July 14, 1995, under the provisions of ORS 238.105 or 238.115 after July 14, 1995; or
(c) The person performed any period of service for a participating public employer before July 14, 1995, that is credited to the six-month period of employment required of an employee under ORS 238.015 before an employee may become a member of the system. [Formerly 238.380]
