From the end of the 18-month period set out in Article 67(5) of the implementing Regulation, interest can be charged by the creditor institution on outstanding claims, unless the debtor institution has made, within six months of the end of the month during which the claim was introduced, a down payment of at least 90 % of the total claim introduced pursuant to Article 67(1) or (2) of the implementing Regulation. For those parts of the claim not covered by the down payment, interest may be charged only from the end of the 36-month period set out in Article 67(6) of the implementing Regulation.
