1. The fees and expenses of the arbitrators shall be reasonable in amount, taking into account the amount in dispute, the complexity of the subject matter, the time spent by the arbitrators and any other relevant circumstances of the case.
2. If there is an appointing authority and it applies or has stated that it will apply a schedule or particular method for determining the fees for arbitrators in international cases, the arbitral tribunal in fixing its fees shall take that schedule or method into account to the extent that it considers appropriate in the circumstances of the case.
3. Promptly after its constitution, the arbitral tribunal shall inform the parties as to how it proposes to determine its fees and expenses, including any rates it intends to apply. Within 15 days of receiving that proposal, any party may refer the proposal to the appointing authority for review. If, within 45 days of receipt of such a referral, the appointing authority finds that the proposal of the arbitral tribunal is inconsistent with paragraph 1, it shall make any necessary adjustments thereto, which shall be binding upon the arbitral tribunal.

5. Throughout the procedure under paragraphs 3 and 4, the arbitral tribunal shall proceed with the arbitration, in accordance with article 17, paragraph 1.
6. A referral under paragraph 4 shall not affect any determination in the award other than the arbitral tribunal’s fees and expenses; nor shall it delay the recognition and enforcement of all parts of the award other than those relating to the determination of the arbitral tribunal’s fees and expenses.
