1. The Board shall fix the date or dates by which, and the manner in which, the estimates as provided in article 19 shall be furnished and shall prescribe the forms therefor.

2. The Board shall, in respect of countries and territories to which this Convention does not apply, request the Governments concerned to furnish estimates in accordance with the provisions of this Convention.

3. If any State fails to furnish estimates in respect of any of its territories by the date specified, the Board shall, as far as possible, establish the estimates. The Board in establishing such estimates shall to the extent practicable do so in co-operation with the Government concerned.

4. The Board shall examine the estimates, including supplementary estimates, and, except as regards requirements for special purposes, may require such information as it considers necessary in respect of any country or territory on behalf of which an estimate has been furnished, in order to complete the estimate or to explain any statement contained therein.

5. The Board, with a view to limiting the use and distribution of drugs to an adequate amount required for medical and scientific purposes and to ensuring their availability for such purposes, shall as expeditiously as possible confirm the estimates, including supplementary estimates, or, with the consent of the Government concerned, may amend such estimates. In case of a disagreement between the Government and the Board, the latter shall have the right to establish, communicate and publish its own estimates, including supplementary estimates.

6. In addition to the reports mentioned in article 15, the Board shall, at such times as it shall determine but at least annually, issue such information on the estimates as in its opinion will facilitate the carrying out of this Convention.
