(a)
Except as provided in subdivision (b), on and after January 1, 1991, the rights and benefits of a former employee of a contracting agency which terminated on or before January 1, 1991, or of his or her beneficiary, shall be the same as if the agency had continued as a contracting agency. Any monthly allowance of that individual, or of his or her beneficiary, that was reduced pursuant to Section 20577 because the contracting agency failed to pay the board the amount of the difference shall not be subject to continued reduction on or after January 1, 1991. As of January 1, 1991, benefits shall be paid at the level provided in the contract prior to that reduction. However, if a former employee of a contracting agency that terminated on or before January 1, 1991, becomes employed by another covered employer after the date of termination, including an employer subject to reciprocity, the benefits shall be calculated by using the highest compensation earned by the individual.
In accordance with Section 20580, an individual who has withdrawn his or her accumulated contributions from the terminated agency shall not be permitted to redeposit any withdrawn contributions upon again becoming a member of this system.
Except as provided in Section 20577.5, benefits shall be reduced proportionally pursuant to Section 20577 prior to the transfer of assets to the pool if the amount of the terminating agency’s assets are less than the actuarial equivalent described in clause (1) of subdivision (a) of Section 20576 and if the agency fails to pay the difference.
(b)
If a contracting agency has not paid the system for any deficit in funding for earned benefits, as determined pursuant to Section 20577, members shall be entitled to the benefits to which members of the plan were entitled 36 months prior to the date the agency notified the board of its intention to terminate its contract or 36 months prior to the date the board notified the agency of its intent to terminate the contract, whichever is earlier. Entitlement to earned benefits under this subdivision shall be subject to Section 20577.5.
