The current text of the IAEA Statute has been amended three times by application of the procedure laid down in paragraphs A and C of Article XVIII. All of these amendments are related to Article VI of the IAEA Statute and have already entered into force.

On 1 October 1999, the IAEA General Conference, at its 43rd regular session, approved two further amendments to the Statute relating to Article VI and to Article XIV.A, respectively.

• The amendment to Article VI of the Statute intends to modify the composition of the IAEA Board of Governors.
• The amendment to Article XIV.A of the Statute intends to replace the current system of annual budgeting for the expenses of the Agency with a system of biennial budgeting.

These amendments have not yet entered into force but pursuant to Paragraph C of Article XVIII, each amendment will come into force for all members of the IAEA when it has been accepted by two-thirds of all the members in accordance with their respective constitutional processes.
