1 The unitary contribution system established with effect from January 1, 1994, replaced the separate contribution systems of WIPO and the six Contribution-financed Unions, that is, each State pays one contribution, irrespective of whether it is a member of WIPO or of one or more of the Contribution-financed Unions. Under the unitary contribution system, there are the following classes corresponding to the units of contribution indicated between parentheses: I (25), II (20), III (15), IV (10), IVbis (7.5), V (5), VI (3), VIbis (2), VII (1), VIII (1/2), IX (1/4), S (1/8), Sbis (1/16) and Ster (1/32).
