59. Any pension or annual allowance shall, at the time prescribed under section 119 of the Act respecting the Québec Pension Plan, be indexed annually at the rate of increase in the Pension Index within the meaning of that Act.
The first adjustment of a pension or of an annual allowance resulting from the indexation, except an adjustment of a deferred pension, shall be carried out proportionately:
(1) to the number of days for which the pension or annual allowance is paid or would be paid during the year in which the contributor retired, in relation to the total number of days in that year;
(2) in the case of an annual allowance granted to the spouse or children while the contributor is eligible for a pension or annual allowance at the time of his death, to the number of days for which the annual allowance is paid or would be paid during the year of death, in relation to the total number of days in that year.
Notwithstanding the foregoing, a deferred pension shall, at the same time, be indexed annually from 1 January following the date on which the contributor ceases to participate in the plan, to 1 January of the year in which he reaches age 60. From 1 January following the date on which a contributor reaches age 60, the deferred pension shall be indexed annually at the rate and at the time provided for in the first paragraph.
