Section 31874.3.

(a) (1) Whenever the percentage of annual increase in the cost of living as of January 1 of each year as shown by the Bureau of Labor Statistics Consumer Price Index for All Urban Consumers exceeds the maximum benefit increase provided in Section 31870, 31870.1, 31870.2, or 31870.3, whichever is applicable, the board of retirement may provide that all or part of the excess percentage increase shall be applied to the retirement allowances, optional death allowances, or annual death allowances increased in Section 31870, 31870.1, 31870.2, or 31870.3. The board shall determine the amount of the excess to be applied, which amount shall not exceed an amount that can be paid from earnings of the retirement fund that are in excess of the total interest credited to contributions and reserves plus 1 percent of the total assets of the retirement fund.

(2) The supplemental increases in excess of the increases applied to the retirement allowances, optional death allowances, or annual death allowances pursuant to Section 31870, 31870.1, 31870.2, or 31870.3 shall not become a part of the retirement allowances, optional death allowances, or annual death allowances to be increased by subsequent increases under Section 31870, 31870.1, 31870.2, or 31870.3.

(3) This subdivision shall be operative in any county that has elected by a majority vote of the board of supervisors to make either Section 31870, 31870.1, 31870.2, or 31870.3 applicable in that county.

(b) (1) The board of retirement may, instead of taking action pursuant to subdivision (a), provide supplemental cost-of-living increases, effective on a date to be determined by the board, to the retirement allowances, optional death allowances, or annual death allowances increased in Section 31870, 31870.1, 31870.2, or 31870.3; provided however, that only those members shall be eligible for this increase whose accumulations established by Section 31870, 31870.1, 31870.2, or 31870.3 shall equal or exceed 20 percent as of January 1 of the year in which the board of retirement adopts an increase under this subdivision.

(2) The supplemental increases to the retirement allowances, optional death allowances or annual death allowances increased in Section 31870, 31870.1, 31870.2, or 31870.3 shall not become a part of the retirement allowances, optional death allowances or annual death allowances to be increased by subsequent increases under Section 31870, 31870.1, 31870.2, or 31870.3.

(3) This subdivision shall be operative in any county that has elected by a majority vote of the board of supervisors to make either Section 31870, 31870.1, 31870.2, or 31870.3 applicable in that county.

(c) (1) The board of retirement may, instead of taking action pursuant to subdivision (a) or (b), provide supplemental cost-of-living increases, on a prefunded basis and effective on a date to be determined by the board, to the retirement allowances, optional death allowances, or annual death allowances increased in Section 31870, 31870.1, 31870.2, or 31870.3; provided however, only those members shall be eligible for this increase whose accumulations established by Section 31870, 31870.1, 31870.2, or 31870.3 equal or exceed 20 percent as of January 1 of the year in which the board of retirement takes action pursuant to this subdivision.

(2) The supplemental increases to the retirement allowances, optional death allowances, or annual death allowances increased in Section 31870, 31870.1, 31870.2, or 31870.3 shall become a part of the retirement allowances, optional death allowances, or annual death allowances and shall serve to reduce the accumulations established by Section 31870, 31870.1, 31870.2, or 31870.3, as applicable, by the same percentage as the payment that is made pursuant to this section.

(3) Before the board of retirement provides benefits pursuant to this subdivision, the costs of the benefits shall be determined by a qualified actuary and the board of retirement shall, with the advice of the actuary, provide for the full funding of the benefits utilizing funds in the reserve against deficiencies established pursuant to Section 31592.2, using surplus earnings that exceed 1 percent of the total assets of the retirement system.

(4) This subdivision shall be operative in any county that has elected by a majority vote of the board of supervisors to make either Section 31870, 31870.1, 31870.2, or 31870.3 applicable in that county.

(d) Upon adoption by any county providing benefits pursuant to this section, of Article 5.5 (commencing with Section 31610) of this chapter, the board of retirement shall, instead, pay those benefits from the Supplemental Retiree Benefit Reserve established pursuant to Section 31618.
