210.4. The amount referred to in paragraph 5 of the first paragraph of section 210.5 that must be used for a year subsequent to the year 2016 is to be adjusted annually in such a manner that the amount used for that year is equal to the total of the amount used for the preceding year and the product obtained by multiplying that amount so used by the factor determined by the formula(A/B) – 1.
In the formula in the first paragraph,(1) A is the average all-items Consumer Price Index for Québec excluding alcoholic beverages, tobacco products and recreational cannabis for the 12-month period that ended on 30 September of the year preceding that for which an amount is to be adjusted; and
(2) B is the average all-items Consumer Price Index for Québec excluding alcoholic beverages, tobacco products and recreational cannabis for the 12-month period that ended on 30 September of the year immediately before the year preceding that for which the amount is to be adjusted.
For the purposes of the first paragraph, where the factor determined by the formula in that paragraph is less than zero, it is deemed to be equal to zero.
If the factor determined by the formula in the first paragraph has more than four decimal places, only the first four decimal digits are retained and the fourth is increased by one unit if the fifth is greater than 4.
If the amount that results from the adjustment provided for in the first paragraph is not a multiple of $100, it is to be rounded to the nearest multiple of $100 or, if it is equidistant from two such multiples, to the higher multiple.
