Employer’s contributions
L5.—(1) An employing authority shall contribute to the fund in each year of any period of three years for which a certificate is required under regulation L4(1), a sum equal to the presumed contribution for that year, increased or, as the case may be, reduced in accordance with any individual adjustment specified for the year in respect of the body under regulation L4(1)(b).
(2) The employing authority shall, during each year of every such period as is mentioned in paragraph (1), pay to the fund at the end of each of the intervals determined under regulation L7, on account of the sum required by paragraph (1) to be paid in that year, a sum equal to the presumed contribution for that interval, increased or, as the case may be, reduced by—
(a)any percentage, or
(b)a part, proportionate to the length of the interval, of any amount expressed in money terms,
that has been specified as an individual adjustment for the year in respect of the body under regulation L4(1)(b).
(3) For the purposes of paragraphs (1) and (2), the presumed contribution for any period for an employer is a sum equal to the common percentage for the year in question of the remuneration on which contributions have during that period been paid to the fund under regulation C3, C5 or C6 by its employees who are members; and in this paragraph “the common percentage” means the common rate of employer’s contribution specified under regulation L4, expressed as a percentage.
(4) Where a standard retirement pension and standard retirement grant are payable under regulation D6, the employing authority shall pay to the Committee such an amount as may be actuarially determined which represents the cost to the Committee of paying such pension and grant before the member has attained normal retirement age.
(5) If all or part of any sum due under paragraph (2) or (4) remains unpaid at the end of the period of 10 days after the date on which it becomes due, the Committee may require the employing authority to pay interest on the amount remaining unpaid, calculated at one per cent. above base rate on a day to day basis from the due date of payment to the date of payment, and compounded with three-monthly rests.
