For the purposes of applying Article 6 of the implementing Regulation, at the latest three months after the applicable legislation has been determined or the institution responsible for paying the benefits has been identified, the institution which provisionally paid the cash benefits shall draw up a statement of the amount provisionally paid and shall send it to the institution identified as being competent.
The institution identified as being competent for paying the benefits shall deduct the amount due in respect of the provisional payment from the arrears of the corresponding benefits it owes to the person concerned and shall without delay transfer the amount deducted to the institution which provisionally paid the cash benefits.
If the amount of provisionally paid benefits exceeds the amount of arrears, or if arrears do not exist, the institution identified as being competent shall deduct this amount from ongoing payments subject to the conditions and limits applying to this kind of offsetting procedure under the legislation it applies, and without delay transfer the amount deducted to the institution which provisionally paid the cash benefits.
