5.—(1) Without prejudice to the previous provisions of this Schedule, a person who has made, or whose widow or widower has made, one or more payments under regulation C7(15) or (19) of the 1992 regulations is entitled to count as a period of membership in whole-time service an additional period of an amount equal to the appropriate proportion of the additional period specified in the notice of election under regulation C7(5) of the 1992 regulations.
(2) In sub-paragraph (1) the “appropriate proportion” means the proportion which the person’s contractual hours of employment as at the relevant date (within the meaning of paragraph 2 of Schedule 10 to the 1992 regulations) bears to the contractual hours of a comparable whole-time employment as at that date.
(3) Where a person has become entitled under sub-paragraphs (1) and (2) to count an additional period as a period of membership in whole-time service by virtue of a lump sum payment having been made in accordance with regulation C7(19) of the 1992 regulations—
(a)the additional period shall be treated as having been able to be counted at the time when the person ceased to be a member; and
(b)the person shall be entitled to receive, within one month after making the lump sum payment, a sum equal to the additional amount he would have received if any benefits already paid to him had been calculated by reference to the increased period of membership.
(4) Regulation C17 (notice to discontinue contributions) applies to payments under regulation C7(15) of the 1992 regulations as it applies to the payments there mentioned, and a person who so discontinues such payment shall be entitled to count under sub-paragraphs (1) and (2) as membership in whole-time service an additional period equal to the appropriate proportion of the length of the period of membership in whole-time service which he would have been entitled to count under that paragraph if payment had been completed.
(5) Where a person began to make payments under regulation C7(15) of the 1992 regulations but ceases to be a member before he has completed payment of the sum payable by him under regulation C8(9) of those regulations—
(a)if he so ceases on his death or on ceasing to hold his employment by reason of permanent ill-health or infirmity of mind or body, he shall be treated as having completed payment of that sum;
(b)except where paragraph (c) applies, if he so ceases for any other reason he shall be entitled to count under sub-paragraphs (1) and (2) as membership in whole-time service an additional period equal to the appropriate proportion of the period of membership in whole-time service which he would have been entitled so to count if payment had been completed; and
(c)if he so ceases by reason of his ceasing to be employed by a LGPS employer and within one month after the date on which he so ceases he pays the Committee a capital sum equal to the total of the instalments remaining unpaid, he shall then be treated as having completed payment.
(6) In sub-paragraphs (4) and (5) “appropriate proportion” means the proportion which the aggregate of the total amount paid by way of instalments under paragraph (15) of regulation C7 of the 1992 regulations and this paragraph and the amount paid or payable by the employing authority under paragraph (13) or, as the case may be, paragraph (14) of that regulation and under this paragraph bears to the total sum payable by him and his employing authority under those provisions.
