Signature of this Memorandum constitutes:

(a) agreement on the initial data for ICBMs and SLBMs of existing types specified in Section I of this Memorandum;

(b) inclusion of the data contained in Sections I, II, III, and IV and Annexes A, B, C, D, E, F, G, H, and I to this Memorandum, and the data provided pursuant to Annex J to this Memorandum; and

(c) acceptance of the categories of data contained in this Memorandum.

The Parties, in signing this Memorandum, acknowledge that each of them is responsible for the accuracy of only its own data, provided, however, that the Parties' agreement with respect to the initial data for ICBMs and SLBMs of existing types specified in Section I of this Memorandum shall not be abrogated thereby.

This Memorandum is an integral part of the Treaty and shall enter into force on the date of entry into force of the Treaty and shall remain in force so long as the Treaty remains in force. The provisions of paragraphs 4-10 of Annex J to this Memorandum shall apply provisionally for a 12-month period beginning from the date of signature of the Treaty, unless, before the expiration of this period:

(a) a Party communicates to the other Party its decision to terminate the provisional application of such provisions; or

(b) the Treaty enters into force.

The Parties may agree to extend the provisional application of these provisions for additional periods, subject to the same conditions specified in subparagraphs (a) and (b) of this paragraph.

As provided for in subparagraph (b) of Article XV of the Treaty, the Parties may agree upon such additional measures as may be necessary to improve the viability and effectiveness of the Treaty. The Parties agree that, if it becomes necessary to change the categories of data contained in this Memorandum or to make other changes in this Memorandum that do not affect substantive rights or obligations under the Treaty, they shall use the Joint Compliance and Inspection Commission to reach agreement on such changes, without resorting to the procedure for making amendments set forth in Article XVIII of the Treaty.
