136. The basic monthly amount of the surviving spouse’s pension of a spouse to whom a retirement pension is payable under this Act or under a similar plan is equal(a) in the case of a spouse who is under 65 years of age, to the amount of the flat benefit which, if no retirement pension were payable to him, would be included in his surviving spouse’s pension for the month for which the basic monthly amount is established, to which the aggregate of the following three amounts is added:(1) the lesser of E and F, calculated as follows:
a × 37.5% = E
c – d = F;
(2) 50% of the amount established in accordance with section 137.1; and
(3) 50% of the amount established in accordance with section 137.2;
(b) in the case of a spouse who is 65 years of age or over, to the aggregate of the three following amounts:(1) the lesser of the following amounts:
i. c – d; and
ii. the greater of G and H, calculated as follows:
a × 37.5% = G
(a × 60%) – (d × 40%) = H;
(2) 50% of the amount established in accordance with section 137.1; and
(3) 50% of the amount established in accordance with section 137.2;
where
“a” is the amount established in accordance with section 137;
“c” is the maximum base monthly retirement pension for the year that includes the month for which the basic monthly amount is established, calculated in accordance with section 116.6 and adjusted according to section 120.1 by taking into account the age of the surviving spouse at the time of retirement, and according to section 120.2, taking into account the fact that the ratio by which the adjustment factor is multiplied in those two sections is equal to one;
“d” represents the amount of the retirement pension, calculated as provided in subparagraph a of the first paragraph of section 120 and adjusted in accordance with section 119, which is payable to the surviving spouse for the month for which the basic monthly amount is established, calculated without taking account either of a partition, if any, of the retirement pension effected pursuant to sections 158.3 to 158.8 or a similar plan, or of an additional pension established under section 120.3, and to which is added, if applicable, the additional amount for disability after retirement.
Nevertheless, if the basic monthly amount thus calculated is less than zero, the amount is deemed to be nil.
