(c) Expenses not attributable exclusively to the Union but also to one or more other Unions administered by the Organization shall be considered as expenses common to the Unions. The share of the Union in such common expenses shall be in proportion to the interest the Union has in them.
(2) The budget of the Union shall be established with due regard to the requirements of coordination with the budgets of the other Unions administered by the Organization.
(3) The budget of the Union shall be financed from the following sources:

Class II ............... 20
Class III .............. 15
Class IV .............. 10
Class V ................. 5
Class VI ................ 3
Class VII ............... 1
(b) Unless it has already done so, each country shall indicate, concurrently with depositing its instrument of ratification or accession, the class to which it wishes to belong.

Any such change shall take effect at the beginning of the calendar year following the said session.
(c) The annual contribution of each country shall be an amount in the same proportion to the total sum to be contributed to the budget of the Union by all countries as the number of its units is to the total of the units of all contributing countries.
(d) Contributions shall become due on the first of January of each year.
(e) A country which is in arrears in the payment of its contributions may not exercise its right to vote in any of the organs of the Union of which it is a member if the amount of its arrears equals or exceeds the amount of the contributions due from it for the preceding two full years. However, any organ of the Union may allow such a country to continue to exercise its right to vote in that organ if, and as long as, it is satisfied that the delay in payment is due to exceptional and unavoidable circumstances.
(f) If the budget is not adopted before the beginning of a new financial period, it shall be at the same level as the budget of the previous year, as provided in the financial regulations.

(a) The Union shall have a working capital fund which shall be constituted by a single payment made by each country of the Union. If the fund becomes insufficient, the Assembly shall decide to increase it.
(b) The amount of the initial payment of each country to the said fund or of its participation in the increase thereof shall be a proportion of the contribution of that country for the year in which the fund is established or the decision to increase it is made.
(c) The proportion and the terms of payment shall be fixed by the Assembly on the proposal of the Director General and after it has heard the advice of the Coordination Committee of the Organization.
(a) In the headquarters agreement concluded with the country on the territory of which the Organization has its headquarters, it shall be provided that, whenever the working capital fund is insufficient, such country shall grant advances. The amount of these advances and the conditions on which they are granted shall be the subject of separate agreements, in each case, between such country and the Organization. As long as it remains under the obligation to grant advances, such country shall have an ex officio seat on the Executive Committee.
(b) The country referred to in subparagraph (a) and the Organization shall each have the right to denounce the obligation to grant advances, by written notification. Denunciation shall take effect three years after the end of the year in which it has been notified.
