The provision in Article 97, paragraph 7, subparagraph (a) of the Social Insurance Transactions Regulation, which governs the earnings subject to premiums for insured individuals under Article 4, paragraph 1, subparagraph (a), had previously stated; "Provided that no meals are provided at the workplace or its premises, any payments made under the name of meal allowances, whether directly to the insured or to third parties on their behalf, shall not be considered in calculating earnings subject to premiums, up to the amount obtained by multiplying the daily minimum wage by a rate determined by the Institution's Board of Directors and the number of days actually worked."
