In May 2010, it was announced that the tournament would be moved to odd-numbered years from 2013 in order to prevent the tournament from taking place in the same year as the World Cup. It also meant there were two tournaments within twelve months in January 2012 (co-hosted by Gabon and Equatorial Guinea) and January 2013 (hosted by South Africa). The change of FIFA Confederations Cup from a biennial to a quadrennial tournament, and the switching of the Africa Cup of Nations from even to odd-number years, meant that some previous Africa Cup of Nations champions such as Egypt, Zambia, and Ivory Coast (winners of the 2010, 2012, and 2015 tournaments respectively) were deprived from participating in the Confederations Cup tournament.
