The ATP has announced that the group names will be changed from A and B to that of former champions of the event. In 2015 the groups will be renamed after the first two champions Stan Smith (1970) and Ilie Năstase (1971-73, 75).
The eight players who qualify for the event are split into two groups of four. During this stage, players compete in a round-robin format (meaning players play against all the other players in their group). The two players with the best results in each group progress to the semifinals, where the winners of a group face the runners-up of the other group. This stage, however, is a knock-out stage. The doubles competition uses the same format.
The ATP World Tour Finals has a round-robin format, with eight players/teams divided into two groups of four. The eight seeds are determined by the ATP Rankings and ATP Doubles Team Rankings on the Monday after the last ATP World Tour tournament of the calendar year. All singles matches are the best of three tie-break sets, including the final. All doubles matches are two sets (no ad) and a Match Tie-break.
