The amounts of the fees referred to in Article 38 and the proportion referred to in Article 39 shall be fixed at such a level as to ensure that the revenue in respect thereof is sufficient for the budget of the Organisation to be balanced.
However, if the Organisation is unable to balance its budget under the conditions laid down in paragraph 1, the Contracting States shall remit to the Organisation special financial contributions, the amount of which shall be determined by the Administrative Council for the accounting period in question.
These special financial contributions shall be determined in respect of any Contracting State on the basis of the number of patent applications filed in the last year but one prior to that of entry into force of this Convention, and calculated in the following manner:
one half in proportion to the number of patent applications filed in that Contracting State;
one half in proportion to the second highest number of patent applications filed in the other Contracting States by natural or legal persons having their residence or principal place of business in that Contracting State.
However, the amounts to be contributed by States in which the number of patent applications filed exceeds 25 000 shall then be taken as a whole and a new scale drawn up in proportion to the total number of patent applications filed in these States.
Where the scale position of any Contracting State cannot be established in accordance with paragraph 3, the Administrative Council shall, with the consent of that State, decide its scale position.
The special financial contributions shall be repaid with interest at a rate which shall be the same for all Contracting States. Repayments shall be made in so far as it is possible to provide for this purpose in the budget; the amount thus provided shall be distributed among the Contracting States in accordance with the scale referred to in paragraphs 3 and 4.
The special financial contributions remitted in any accounting period shall be repaid in full before any such contributions or parts thereof remitted in any subsequent accounting period are repaid.
