Wild cards for the tournament had to be given to either local players or players who had won Wimbledon, the US Open, the Virginia Slims or Colgate Series championships or were previous winners of the tournament. All tournaments used a seeded draw with the number of seeds depending on the draw size.
The tournaments of the Colgate Series were divided into four groups – AAAA, AAA, AA and A – based on prize money. Points were allocated based on these groups and the finishing position of a player in a tournament. The points allocation – with doubles points listed in brackets – was:
The total bonus pool for the Colgate Series was $675,000, an increase of $75,000 compared to the previous year, and was divided over singles ($540,000) and doubles ($135,000). The 35 highest points ranking singles players and the top 20 in doubles qualified to receive a share of the bonus pool. The distribution ranged from $100,000 for the first placed singles player to $3,000 for the 35th placed player. The first placed doubles player received $22,000 bonus while the 20th placed player received $2,000. In order to be eligible for a share of the respective bonus pools players had to a) participate in a minimum of seven singles or three doubles tournaments and b) accept invitation for the series championships if qualified based on merit. Players who ended on equal points were ranked in order of the number of tournaments played.
