(a) The dollar amounts in AS 46.04.040 change, as provided in this section, according to and to the extent of changes in the Consumer Price Index for all urban consumers for the Anchorage metropolitan area compiled by the Bureau of Labor Statistics, United States Department of Labor (the index). The index for January 1990 is the reference base index.

(b) The dollar amounts change on October 1 of each third year according to the percentage change between the index for January of that year and the most recent index used to determine whether to change the dollar amounts. After calculation of the new amounts, the resulting amounts shall be rounded to the nearest cent.

(c) If the index is revised, the percentage of change is calculated on the basis of the revised index. If a revision of the index changes the reference base index, a revised reference base index is determined by multiplying the reference base index applicable by the rebasing factor furnished by the United States Bureau of Labor Statistics. If the index is superseded, the index referred to in this section is the one represented by the Bureau of Labor Statistics as reflecting most accurately changes in the purchasing power of the dollar for Alaskan consumers.

(d) The department shall adopt a regulation announcing

(1) on or before June 30 of each third year, the changes in dollar amounts required by (b) of this section; and

(2) promptly after the changes occur, changes in the index required by (c) of this section, including, if applicable, the numerical equivalent of the reference base index under a revised reference base index and the designation or title of any index superseding the index.

(e) The department shall also provide notification of a change in dollar amounts required under (b) of this section to the clerks of court in each judicial district of the state.
