2. For the purposes of section 1, the amount of the benefit dated 1 January 2000 shall be equal to $5,221.40. For each year in question after that date and until the year where the pension has become payable, the benefit is indexed at the time prescribed by section 119 of the Act respecting the Québec Pension Plan (chapter R-9) by the rate of increase in the pension index and, for following years, indexed as provided in section 64 of the Act respecting the Civil Service Superannuation Plan (chapter R-12), reduced in accordance with section 63.3 or paragraph 1 of the first paragraph of section 76 of that Act, as the case may be, even if no pension under the Act respecting the Québec Pension Plan is paid.
Notwithstanding the foregoing, the calculation applies only with respect to that part of the pension relating to the years of service credited before 1 January 1992, and the amount referred to in the first paragraph is multiplied by the fraction that the number of those years is of the total number of years of service credited.
