10. The gross income of a worker is revalorized on 1 June of each year following the beginning of the most recent period of total temporary disability for which he was granted an indemnity under the Workmen’s Compensation Act (chapter A-3), by multiplying the gross income by the ratio of the Consumer Price Index for the current year to that for the preceding year. Notwithstanding the foregoing, that gross income must not be revalorized prior to 1 June 1986.
For the years 1986 to 1991, the rates of revalorization are 4%, 4.1%, 4.4%, 4.1%, 4.8%, and 4.8% respectively.
The gross income thus revalorized must not be:(1) less than the annual income determined on the basis of the minimum wage and the regular work week in force on 1 June of the year for which the computation is made for the first time; or
(2) greater than the maximum yearly insurable earnings established in accordance with section 66 of the Act respecting industrial accidents and occupational diseases (chapter A-3.001) and in force on 1 June of the year for which the computation is made.
