62. Upon the death of a contributor who, at the time of his death, was entitled under section 60 to receive an immediate or a deferred pension, his surviving spouse and children are eligible for an annual allowance established on the basis of the pension that the contributor was receiving or, where applicable, was or would have been entitled to obtain upon his death, not taking into account the reduction provided for in section 57.
In the case of the surviving spouse, the immediate annual allowance shall equal half the contributor’s pension.
In the case of each child, the immediate annual allowance shall equal one-tenth of the contributor’s pension or, where the contributor died without leaving a surviving spouse or where the spouse is deceased, shall equal one-fifth of that pension.
Notwithstanding the foregoing, the total allowances paid pursuant to the third paragraph shall not exceed two-fifths of the contributor’s pension or, where the contributor died without leaving a surviving spouse or where the spouse is deceased, shall not exceed four-fifths of the pension that the contributor would have received on the date of his spouse’s death.
