  highest prize money level. (Note: 125,000 + H points are shown).

First Round Losers

First round losers always receive 1 point. Any player who reached the second
round by drawing a bye and then loses will receive second round prize money
but only 1 point.


Bonus Points

Main Draw Bonus Points
----------------------

The following points are awarded for defeating a player ranked #1 through 200
or a doubles team ranked 2 through 400. The match must actually be played,
not a walk-over.  Double Bonus Points are awarded instead of Regular Bonus
Points in the case of Grand Slam matches and best-of-5-set finals in Super
9 ATP tournaments.

You compute the sum of the doubles rankings of the opposing team
members (which could only be 2 if they were tied for #1) and thus
there is no #1 listed, and all the rankings are twice as much as the
corresponding singles rankings.

Qualifying Points
-----------------
A player or team gaining entry to an event through a qualifying
competition shall receive one half the points awarded to a second
round loser in that event as bonus points, in addition to whatever
points they actually earn in the event. Lucky losers do not receive
these bonus points. There are no bonus points awarded in the qualifying
event itself, regardless of opponents' rankings.


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.

 2.2                 WTA - WTA Tour Rankings (Women)

The women's computer rankings are determined as follows:

Points are awarded based on how far a player advances in a tournament.
Bonus points, based on the rankings of opponents beaten in each round,
are added. The only exception is the WTA Championships, where a player
gets the higher between (1) ranking points she gets based on the method
described above and (2) her ranking point average going into the WTA
Championship (described below) plus any bonus points she receives
there.  This exception applies only to 1996 and earlier years.

On December 23, 1996, the WTA ranking system transforms from an
averaging system to a lump-sum system.  Prior to this date, the total
points awarded for each tournament played within a 52-week period are
added & then divided by the number of tournaments played in that same
period (minimum divisor of 14 tournaments: if one plays 13 or fewer,
her points are still divided by 14).

As of December 23, 1996, a simple sum of the ranking points awarded
for each tournament played during the prior 52 weeks will be computed.
This method is similar to the current ATP ranking system.  However,
unlike the ATP rankings, all results will still count under the
modified WTA ranking method.  A player who plays more tournaments
will enjoy more of a ranking benefit under this new system.

The current ranking system awards points based on the tier of a
tournament as well as the type of draw (the number of players in the
main draw in a tournament).

 2.3            WTA - WTA Tour Championships Points (Women)

                Written by Shun Cheung (shun.cheung@att.com)

The WTA Championship Points were formerly known as the Virginia Slims
Bonus Pool Points (1994) and the Kraft Tour Points (when Kraft General 
Foods sponsored the tour).

The WTA Tour Championship points are used to determine the eligibility
for the year-end WTA Tour Championships at the Madison Square Garden in
New York City (the top 16 qualify) and each player's share of the bonus
money pool.

The WTA Tour Championship points for each player is the simple sum of
points she receives from all tournaments in a calendar year.  As of 1996,
the number of WTA Championships points a player earns for a performance
at a given tournament is equivalent to the number of WTA Tour rankings
points, including bonus points, received for that tournament.  Ranking
points details are outlined in section 2.2 of the FAQ.

As of 1997, the WTA Tour rankings will be used to determine a player's
eligibility for the WTA Tour Championships, eliminating the need to
maintain a separate WTA Tour Championships points table.
