(1) As soon as practicable after January 1 each year, the Public Employees Retirement Board shall determine the percentage increase or decrease in the cost of living for the previous calendar year, based on the Portland-Salem, OR-WA, Consumer Price Index for All Urban Consumers for All Items, as published by the Bureau of Labor Statistics of the United States Department of Labor. Before July 1 each year, the board shall adjust every pension payable under ORS 238A.180, 238A.185 and 238A.190, every disability benefit under ORS 238A.235 and every death benefit payable under ORS 238A.230 by multiplying the monthly payment by the percentage figure determined by the board. If a person has been receiving a pension or benefit for less than 12 months on July 1 of a calendar year, the board shall make a pro rata reduction of the adjustment based on the number of months that the pension or benefit was received before July 1 of the year. The adjustment shall be made for the payments payable on August 1 and thereafter

(2) An increase or decrease in the benefit payments under this section may not exceed two percent in any year. A pension or death benefit may not be adjusted to an amount that is less than the amount that would have been payable if no cost-of-living adjustment had been made since the pension or death benefit first became payable.
