49 Variation of entitlement

(1) Where the salary of a contributor referred to in regulation 47 is increased after, but as from a date before, the date of his retirement and the number of units of pension to which he would become entitled if he had been a contributor who had not so retired is greater than the number of units of pension to which he was entitled immediately before his retirement, he may elect to contribute for additional units of pension, but so that the total number of units does not exceed that first‑mentioned number of units. (2) In calculating entitlement to additional units of pension, no account shall be taken of any election to reduce the number of units except in direct consequence of a reduction in salary. (3) The contributions payable by the contributor for the additional units shall be an amount which in the opinion of the Board is necessary to purchase the additional units if they had been taken into account under regulation 47. (4) Upon payment of the amount referred to in subregulation (3), pension in respect of the additional units becomes payable as from the date of retirement.
