The tournament format changed from previously years. The sixteen teams were allocated in four groups of four teams each. The first three teams in each group qualified for the qualifying round. The last team of each group played for the 13th–16th position in the Classification Games. The twelve teams qualified for the qualifying round were allocated in two groups of six teams each. The results of the games between the teams in the preliminary round were taken into account for the ranking in the qualifying round. The two top teams of each group qualified for the semifinals.
