IMU has five groups of membership. Membership in Group n provides n votes in the General Assembly. The dues increase nonlinearly with the group number. For instance, the dues for group V are twelve times the dues for group I. The Statutes describe this more formally. The adherence of a country is in one of the five groups I-V with corresponding voting powers and contributions as set out in the Statutes. A country may change its classification with the approval of the members of the Union upon recommendation of the Executive Committee.
