Qualifying Points
---------------------------
A player gaining entry to an event through a qualifying competition shall receive
one half the points awarded to a second round loser in the main draw, in addition
to whatever points they
actually earn in the event.

In Grand Slam qualifying tournaments, players receive 1 point for losing in the
first round of qualifying, 3 points for losing in the second round, and 5 points
for losing in the third round.  In ATP  Championship Series Tournaments, players
in qualifying receive 1 point for losing in the first round and one quarter of the
points a main draw second round loser receives (plus bonus points) for losing in
the second round.  As of 1997 bonus points for beating ranked players
are awarded
in Grand Slam and ATP Championship Series events.  Neither ranking nor bonus
points are awarded to players who fail to qualify for ATP World Series tournaments.


Ranking Penalty: Withdrawals After 12 Noon Eastern Time USA
----------------------------------------------------------------------------------
If a player withdraws from an event after 12 Noon Eastern Time USA on the Friday
before the start of the event, he will be penalized in the rankings by one event
per 12 month period, e.g. he will be ranked by his best 13 events instead of his
best 14 events after one such
infraction, by his best 12 events after 2 such
infractions, etc. The penalty shall remain in force for 52 weeks after the time of
the infraction.  This penalty shall be waived if, within the first 3 days of the
main draw, the player is examined on-site by the tournament doctor and deemed
incapable of competing at a professional level.
