116.1. For the calculation of a benefit, a contributor’s base pensionable earnings for each month are his base unadjusted pensionable earnings for that month multiplied by the ratio between the average Maximum Pensionable Earnings relating to the year for which his average base monthly pensionable earnings are established and the Maximum Pensionable Earnings for the year that includes that month.
The average Maximum Pensionable Earnings relating to a year is equal(a) if the year concerned is prior to 1998, to the average Maximum Pensionable Earnings for that year and the two preceding years, except that, for the year 1967, only one preceding year is considered,
(b) if the year concerned is the year 1998, to the average Maximum Pensionable Earnings for that year and the three preceding years, except in the case of the calculation of a retirement pension or a disability pension payable from a date prior to 1 July 1998 or a surviving spouse’s pension payable in respect of a death occurring before 1 July 1998, in which cases only two preceding years shall be considered;
(c) if the year concerned is subsequent to 1998, to the average Maximum Pensionable Earnings for that year and the four preceding years.
However, if the contributor is 65 years of age or over on 1 January 1998, the average Maximum Pensionable Earnings shall be calculated in accordance with subparagraph a of the second paragraph, regardless of the year considered. The same applies to the calculation of the maximum monthly retirement pension used to establish the amount of the surviving spouse’s pension where the pension is combined with a retirement pension payable under this Act or a similar plan to a contributor 65 years of age or over on 1 January 1998 or with a disability pension or retirement pension that becomes payable to the contributor under this Act or a similar plan before 1 July 1998.
