Matches tied after regulation were decided by a shoot-out. In 2002, a similar format was used except that draws were allowed and the team earning the most points advanced.

Beginning in 2012, the finals were a two-match aggregate series. The away goals rule for series that finished even on aggregate was first implemented in 2014. Extra time and shoot-outs were used if necessary, although away goals did not apply in extra time.
