The twelve invited teams were split into three groups that played a round-robin tournament. The main eight entrants were identical to the previous year.
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. The Group C winner faced the better 3rd place team from Groups A and B for 5th, with the Group C runner-up facing the other 3rd place team for 7th. Group C's 3rd place team faced the better 4th place team of Groups A and B, while the other two 4th place teams played in the 11th place match.
Points awarded in the group stage follow the standard formula of three points for a win, one point for a draw and zero points for a loss. 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.
