Section 5

Such abatement shall continue to be made until the contributor attains the age of 65 years, if he continues so long to draw salary or pension from the Government, or until such abatement has been made for 35 successive years, counting from the first abatement of his original salary, in either of which events such abatement shall cease.

Such abatement shall be calculated on the salary of the permanent appointment of the contributor irrespective of any temporary increment of salary which he derives from an acting appointment, and irrespective of personal and other allowances except pensionable personal allowances which shall be deemed to be part of the contributor’s salary for the purpose of calculating such abatement.
