2. The Council shall, after having satisfied itself that the estimates submitted by the Government of Iceland in accordance with paragraph 1 of Article VIII have been drawn up in accordance with Article III and with Annexes II and III to this Agreement, authorize the Secretary General to make payments to that Government in respect of each quarter, not later than the first day of the second month of that quarter. The payments shall be based on the estimates referred to and shall constitute advances, subject to adjustment as provided under paragraph 3 of this Article.
