Section 31495.5.

(a) Notwithstanding any other provision of this article, every retirement allowance or death allowance payable, on or after the operative date of this section, to or on account of any member of Retirement Plan E who retires or dies or who has retired or died shall, as of April 1 each year, be increased or decreased by an amount equal to that member's automatic COLA, as defined in subdivision (f) and as calculated by the board of retirement before April 1 of each year. No decrease in the cost of living shall reduce an allowance below the amount being received by the member or his or her beneficiary on the effective date of the allowance or the operative date of this section, whichever is later.

(b) A Retirement Plan E member may elect to purchase an elective COLA, as defined in subdivision (f), with regard to some portion (designated in whole-month increments) or all of his or her months of Retirement Plan E service earned prior to the operative date of this section. The member may also elect to purchase an elective COLA, as defined in subdivision (f), with regard to some portion (designated in whole-month increments) or all of his or her months of Retirement Plan E service purchased pursuant to Section 31490.5, including service rendered after June 4, 2002, but prior to becoming a member of this system.

(c) The election shall be made upon written application signed by the member and filed with the board pursuant to election procedures and during election periods established by the board. The purchase of the elective COLA shall be effective only when the member has paid contributions necessary to purchase the designated amount of service for which he or she shall receive the elective COLA. The amount of required contributions shall be determined by the board, subject to the following:

(1) The cost of purchasing service for elective COLA purposes shall be determined by the board of retirement such that no elective COLA liability shall be borne by the county and no diminution in the funding ratio of the system shall result.

(2) The cost charged to the member for purchasing the elective COLA service shall be based upon the assumption that the member retires at the age of 65 years.

(3) Members may pay for the elective COLA by lump-sum payment or monthly installments over a period to be determined by a resolution adopted by a majority vote of the board of retirement, or both, but in any event prior to the earlier of his or her death or the date that is 120 days after the effective date of his or her retirement.

(4) If a member fails to timely complete the purchase of his or her elective COLA, he or she shall receive an elective COLA calculated only with regard to that amount of service actually purchased.

(5) If a Retirement Plan E member dies prior to retirement, any contributions made toward the purchase of an elective COLA, and all interest credited thereto, shall be refunded to the deceased member's surviving spouse or, if there is no surviving spouse, to the deceased member's surviving child or children under the age of 18 years, divided among those children in equal amounts, or, if there is no surviving spouse or surviving child or children under the age of 18 years, to the deceased member's estate.

(d) If a Retirement Plan E member elects and purchases an elective COLA, then, notwithstanding any other provision of this article, every Retirement Plan E allowance or postretirement death allowance payable on and after the operative date of this section, to or on account of that member who retires or dies or who has retired or died shall, as of April 1 of each year, be increased or decreased by an amount equal to that member's elective COLA as calculated by the board of retirement before April 1 of each year. No decrease in the cost of living shall reduce an allowance below the amount being received by the member or his or her beneficiary on the effective date of the allowance or this provision, whichever is later.

Notwithstanding any other provisions of this section, if a member retires before attaining the age of 65 years, his or her elective COLA shall be actuarially reduced to reflect that earlier retirement age unless, within 120 days after his or her retirement, he or she contributes by lump-sum the amount necessary to complete the purchase of his or her elective COLA as determined by the board. If, upon a member's retirement, the board of retirement determines that a member has paid more contributions than necessary to purchase his or her elective COLA in accordance with subdivision (b), the member shall receive a refund of those excess contributions and all interest credited thereto. Upon retirement or termination of employment, but before he or she begins receiving his or her elective COLA, a member may revoke his or her election to purchase an elective COLA and receive a refund of any contributions made toward the purchase of the elective COLA and all interest credited thereto.

(e) If a Retirement Plan E member or former member is totally disabled, begins receiving disability benefits, other than state-mandated benefits, under a disability plan provided by the employer on or after the operative date of this section, and, on or after that date, his or her employment terminates, then, for purposes of calculating the member's or former member's final compensation, his or her predisability compensation, as previously adjusted in accordance with this subdivision and paragraph (5) of subdivision (f), shall, as of April 1 of each year after his or her employment terminates and during a period for which he or she both remains totally disabled and earns "service" within the meaning of subdivision (g) of Section 31488, be increased or decreased by an amount equal to that member's or former member's predisability compensation adjustment as calculated by the board of retirement before April 1 of each year.

(f) As used in this section:

(1) "Automatic COLA" means, with respect to any member of Retirement Plan E, an amount equal to the allowance then being received (including any automatic or elective COLAs previously received), multiplied by a percentage (rounded to the nearest one-tenth of 1 percent) derived by taking the number of months of service the member earned on and after the operative date of this section, dividing by the member's total months of service, and multiplying by a percentage equal to the lesser of 2 percent or the percentage found by the board of retirement to approximate to the nearest one-half of 1 percent the percentage of annual increase or decrease in the cost of living as of January 1 of each year as shown by the then current CPI, as adjusted for the amount applied from a prior year. For purposes of applying this formula, the amount of any annual cost-of-living increase under the CPI in excess of the 2 percent maximum shall be accumulated and applied in future years in which the annual cost-of-living increase under the CPI is less than the 2 percent maximum.

(2) "CPI" means the Bureau of Labor Statistics Consumer Price Index for All Urban Consumers for the area in which the county seat is situated.

(3) "Elective COLA" means, with respect to any member of Retirement Plan E, an amount equal to the allowance then being received (including any automatic or elective COLAs previously received), multiplied by a percentage (rounded to the nearest one-tenth of 1 percent) derived by taking the number of months of service the member purchased in accordance with subdivision (b), dividing by the member's total months of service, and multiplying by a percentage equal to the lesser of 2 percent or the percentage found by the board of retirement to approximate to the nearest one-half of 1 percent the percentage of annual increase or decrease in the cost of living as of January 1 of each year as shown by the then current CPI, as adjusted for the amount applied from a prior year. For purposes of applying this formula, the amount of any annual cost-of-living increase under the CPI in excess of the 2 percent maximum shall be accumulated and applied in future years in which the annual cost-of-living increase under the CPI is less than the 2 percent maximum.

(4) "Predisability compensation" means a member's last 12 months of compensation earnable preceding the date his or her employment terminates while he or she is receiving disability benefits, other than state-mandated benefits, under a disability plan provided by the employer because he or she is totally disabled. The employer shall provide the board of retirement with the information necessary for a member's predisability compensation to be determined.

(5) "Predisability compensation adjustment" means, with respect to any member or former member of Retirement Plan E qualifying under subdivision (e), an amount equal to that member's or former member's predisability compensation as previously adjusted under this section, multiplied by a percentage equal to the lesser of 2 percent or the percentage found by the board of retirement to approximate to the nearest one-half of 1 percent the percentage of annual increase or decrease in the cost of living as of January 1, of each year as shown by the then current CPI, as adjusted for the amount applied from a prior year. For the purpose of applying this formula, the amount of any annual cost-of-living increase under the CPI in excess of the 2 percent maximum shall be accumulated and applied in future years in which the annual cost-of-living increase under the CPI is less than the 2 percent maximum.

(g) This section shall only be applicable to Los Angeles County and shall not become operative until the board of supervisors of that county elects, by resolution adopted by a majority vote, to make this section operative in the county.

(Amended by Stats. 2004, Ch. 533, Sec. 12. Effective January 1, 2005. Section conditionally operative by its own provisions.)
