The deal gave ISL the commercial rights for the Super-9 tournaments as well as the ATP World Championship.

The ATP also introduced a simplified ranking system and made participation in the Super-9 events mandatory for top players.

[1] This is the complete schedule of events on the 1999 calendar, with player progression documented from the quarterfinals stage.

[2][3][4][5][6][7][8][9] These tables present the number of singles (S), doubles (D), and mixed doubles (X) titles won by each player and each nation during the season, within all the tournament categories of the 1999 ATP Tour: the Grand Slam tournaments, the ATP Tour World Championships and the Grand Slam Cup, the ATP Super 9, the ATP Championship Series, and the ATP World Series.

These are the ATP rankings of the top twenty singles players, doubles players, and the top ten doubles teams on the ATP Tour, at the end of the 1998 ATP Tour,[10][11][12] and of the 1999 season,[13][14][15] with number of rankings points, number of tournaments played, year-end ranking in 1998, highest and lowest position during the season (for singles and doubles individual only, as doubles team rankings are not calculated over a rolling year-to-date system), and number of spots gained or lost from the 1998 to the 1999 year-end rankings.
