Section 21337.1.

(a) All monthly allowances paid by the system to retirees of contracting public agencies, and to survivors and beneficiaries of members and retirees of those agencies, shall annually be increased to 80 percent of the purchasing power of the initial monthly allowance as determined by the board. Adjustments in the purchasing power protection allowance shall be effective with the monthly allowance regularly payable on the first day of May, provided that, in the first year after enactment of the act amending this subdivision, the purchasing power protection allowance adjustment to the monthly allowance payable on the first day of May shall also reflect an adjustment for the period from January 1 through April 30.

(b) Notwithstanding subdivision (a), retirees of contracting public agencies, and survivors and beneficiaries of members and retirees of those agencies, who receive a monthly allowance payable by this system shall also receive, on or after January 1, 2001, a one-time lump-sum payment in an amount equal to the difference, if any, between the purchasing power protection allowance paid between January 1, 2000, and December 31, 2000, and the purchasing power protection allowance that would have been payable if this section had been operative during that period.

(c) The cost of the increase in allowances paid pursuant to subdivisions (a) and (b) shall be paid from the same assets of the employer used in the determination of each employer contribution rate for each membership classification under which service was credited that affects the allowance calculation of the retirees, survivors, or beneficiaries.
