[1] The twelve invited teams were split into three groups that played a round-robin tournament.
Groups A and B, containing the strongest ranked teams, were the only ones in contention to win the title.
The group winners from A and B contested the final, with the runners-up playing for third place.
In the case of two teams being tied on the same number of points in a group, their head-to-head result determined the higher place.
Games were played in five host stadiums in four cities.
