1. Meetings
By invitation of the Society of Crystallographers in Australia and New Zealand, the Twenty-Sixth General Assembly and International Congress of Crystallography were held in person at the Melbourne Convention and Exhibition Centre (MCEC), Australia, and partially in hybrid format, 22–29 August 2023. The meetings were attended by 1788 participants from 66 countries, 1706 of whom attended in person and 82 of whom attended virtually.
The IUCr also sponsored several other meetings that were held in 2023, as detailed in the Report of the Meeting Support Committee (Section 5). In addition, the Executive Committee met in Melbourne, Australia, in August at the time of the Twenty-Sixth Congress and General Assembly of the International Union of Crystallography. The Finance Committee met in March and August to prepare its advice and recommendations on finances, establishment and staff matters.
The most important items of business dealt with by the Executive Committee during their meeting and in e-mail ballots were: editorial policy, pricing policy, review of the work of the Journals Management Board, development of Acta Crystallographica Section E and IUCrData, approval of appointments of Main Editors, approval of appointments of Co-editors, Special Issues, and other matters concerning the IUCr journals; approval of the audited accounts for the previous year; the level of unit contribution and the status of membership subscriptions; sponsorship and financial support for meetings, young scientists' support, revision of internal guidelines; progress with Volumes A, A1, B, C, D, E, F, G, H and I of International Tables for Crystallography and development of associated software; the IUCr Newsletter; the World Database of Crystallographers; marketing and promotional activities; outreach and education; LAAAMP and other activities; OpenLabs and other activities; updates on the Ewald, Struchkov and Bragg Prizes; discussion and consideration of progress of arrangements for the Melbourne Congress; approval of the programme for the Melbourne Congress; review of nominations and election procedures for Officers of the IUCr and for Chairs and members of Commissions; proposals from National Committees for these positions; the IUCr website; approval of publications, jointly with Oxford University Press, in the IUCr/OUP Book Series; the Crystallography in Africa Initiative; staffing requirements in the IUCr office in Chester; risk analysis; and closure of premises and dilapidations.
2. Publications

5. Meeting Support Committee
During the IUCr Executive Committee meeting in Versailles in August 2022, the Sub-committee on the Union Calendar was renamed as the Meeting Support Committee (MSC). This was subsequently approved by the Twenty-Sixth General Assembly.

The IUCr Visiting Professorship scheme aims to support some of the costs of having internationally recognized scientists as lecturers for short courses at workshops or schools organized in developing countries. Support from at least one IUCr Commission is required. Details are available on the IUCr website at https://www.iucr.org/iucr/sponsorship/vp.html.

12. Finances
The Report and Financial Statements for 2023 are given as supporting information.

The cost of the technical-editing office has been divided between the journals and International Tables for Crystallography in percentages based on the staff time spent on each publication. The technical-editing costs for the journals were USD 1 162 318, as compared with USD 1 153 341 in 2022.
Books showed a profit of USD 4883, as compared with a deficit of USD 258 in 2022. The net sales income for books was USD 72 818 in 2023, as compared with USD 67 043 in 2022.
