88.8. The amount of $50,000 referred to in subparagraph 1 of the first paragraph of section 88.2 and in section 88.3 that is to be used to determine the amount of the additional parental contribution for a day of childcare in a year subsequent to 2015, and the amount of $75,000 referred to in subparagraph 2 of the first paragraph of section 88.2 that is to be used to determine if a parent is required to pay an additional contribution for such a day of childcare, must be indexed 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 latter amount by the factor determined by the formula
(A/B) - 1.
In the formula in the first paragraph,(1) A is the overall average Québec consumer price index without alcoholic beverages and tobacco products for the 12-month period that ended on 30 September of the year preceding that for which the amount is to be indexed; and
(2) B is the overall average Québec consumer price index without alcoholic beverages and tobacco products 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 indexed.
If the factor determined by the formula in the first paragraph has more than four decimals, only the first four are retained and the fourth is increased by one unit if the fifth is greater than 4.
