(1) The minimum estimated contribution amount for the calendar year shall be an amount equal to the product of the minimum estimated contribution amount for the calendar year multiplied by the inflation factor adjustment as specified in subparagraph (A) of paragraph (2) of subdivision (h) of Section 17041, rounded off to the nearest dollar.

(2) The inflation factor adjustment used for the calendar year shall be based on the figures for the percentage change in the California Consumer Price Index for all items received on or before August 1 of the calendar year pursuant to paragraph (1) of subdivision (h) of Section 17041.
