10.4(1)Where a pension is paid under this Act to a person who first received the pension after December 31, 1989, but before January 1, 1997, the amount of that pension shall be adjusted as of the first day of each year, commencing with the year following the year in which the pension was first received, by multiplying the amount of the pension that would have been payable for that year if no adjustment had been made under this subsection with respect to that following year, by the ratio that the pension index for that year bears to the pension index for the preceding year or 1.06, whichever is the lesser.
