The ordinary budget includes expenditures pertaining to the ITU Council, the Geneva headquarters, and the various conferences and meetings. The technical cooperation special accounts budget includes administrative expenditure for technical assistance to developing nations and is financed by the UNDP. The publications budget includes production costs of all publications and is self-financed through sales.
At each Plenipotentiary Conference, member countries choose a class of contribution. The lowest classes are reserved for countries designated least developed countries by the United Nations. The ordinary budget is then divided by the number of units assigned to each member. However, regional radio conferences require additional contributions.
All other organizations (private enterprises, international organizations, etc.) that take part in the work of the union's three sectors must also choose a contribution class; however, their units are 1/5th the value of the member countries' contributory unit. Separate contributions must be made for participation in any of the various conferences of the union.
The total budget for 2002–03 amounted to S FR 341,947,736.
