Sec. 106. (1) The dollar amounts in this article designated as subject to change shall change, as provided in this section, according to the Consumer Price Index for Urban Wage Earners and Clerical Workers: U.S. City Average, All Items, 1957-59 equals 100, compiled by Bureau of Labor Statistics, United States Department of Labor, and referred to in this section as the Index. The Index for October, 1971, is the Reference Base Index.

(2) The dollar amounts shall change on July 1 of each even-numbered year if the percentage of change, calculated to the nearest whole percentage point, between the Index at the end of the preceding year and the Reference Base Index is ten percent (10%) or more, except that:

(a) the portion of the percentage change in the Index in excess of a multiple of ten percent (10%) shall be disregarded and the dollar amounts shall change only in multiples of ten percent (10%) of the amounts on March 5, 1971;

(b) the dollar amounts shall not change if the amounts required by this section are those currently in effect pursuant to this article as a result of earlier application of the section; and

(c) in no event shall the dollar amounts be reduced below the amounts appearing in this article on March 5, 1971.

(3) If the Index is revised after December 1967, the percentage of change shall be calculated on the basis of the revised Index. If the revision of the Index changes the Reference Base Index, a revised Reference Base Index shall be determined by multiplying the Reference Base Index by the ratio of the revised Index to the current Index, as each was for the first month in which the revised Index is available. If the Index is superseded, the Index is the one represented by the Bureau of Labor Statistics as reflecting most accurately changes in the purchasing power of the dollar for consumers.

(4) The department shall issue an emergency rule under IC 4-22-2-37.1 announcing:

(a) on or before April 30 of each year in which dollar amounts are to change, the changes in dollar amounts required by subsection (2); and

(b) promptly after the changes occur, changes in the Index required by subsection (3), including, when 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.

An emergency rule adopted under this subsection expires on the date the department is next required to issue a rule under this subsection.

(5) A person does not violate this article through a transaction otherwise complying with this article if the person relies on dollar amounts either determined according to subsection (2) or appearing in the last rule of the department announcing the then current dollar amounts.
