Article 9

any assets acquired from the international funds of an Allied Headquarters under its capital budget and no longer required by the Headquarters shall be disposed of under arrangements approved by the North Atlantic Council and the proceeds shall be distributed among or credited to the Parties to the North Atlantic Treaty in the proportions in which they have contributed to the capital costs of the Headquarters. The receiving State shall have the prior right to acquire any immovable property so disposed of in its territory, provided that it offers terms no less favourable than those offered by any third party;

any land, buildings or fixed installations provided for the use of an Allied Headquarters by the receiving State without charge to the Headquarters (other than a nominal charge) and no longer required by the Headquarters shall be handed back to the receiving State, and any increase or loss in the value of the property provided by the receiving State resulting from its use by the Headquarters shall be determined by the North Atlantic Council (taking into consideration any applicable law of the receiving State) and distributed among or credited or debited to the Parties to the North Atlantic Treaty in the proportions in which they have contributed to the capital costs of the Headquarters.
