The decrees mentioned in article D. 5424-39 set each year the rates of contributions to be paid by companies and the amount of the reserve fund intended to ensure the reimbursement of bad weather daily allowances. When this amount is exceeded, the Board of Directors of the Caisse Nationale de Surcompensation may, if the Ministers responsible for Employment and the Economy, who have been informed in advance, have not made their opposition known within one month of receiving this information, reduce the companies’ contributions for the remainder of the year by up to 20% of the rates initially set.
