The proposed second amendment of the Articles of Agreement is responsible for three classes of legislation that members of the Fund have adopted or are in the process of adopting. The first and most obvious class is legislation that amends the member’s Bretton Woods legislation in order to authorize the member to accept the proposed second amendment of the Articles and to enable it to perform its obligations under the Articles when amended. The second class also is legislation that was to be expected. It consists of measures to modify or abrogate the domestic law by or under which a par value for the member’s currency is established. The third class consists of a variety of measures that are considered necessary or desirable because of the changes introduced by the other two kinds of legislation. For example, the amendment of the Bretton Woods Agreements Act of the United States,10 which is to take effect on the occasion of the proposed second amendment of the Articles, has modified the Gold Reserve Act of 1934 (31 U.S.C. 405b).11
