The competition was composed by 4 teams, placed into 2 semi-final games, with the winners going on to play the final and the losers to play the 3rd/4th place playoff. Only the last edition was composed by 8 teams, thus placed into 4 quarter-final games (with the losers playing 2nd to 8th place play-offs). Only the editions organized since 1999 were considered official.[1]
