The 1998 WTA Tour, sponsored by Corel, comprises 53
tournaments, together with two affiliated ITF events, the
Federation Cup and Hopman Cup. Each Corel WTA tournament
is graded into tiers. There are four such tiers, Tier I
events being the most prestigious (and usually boasting
the highest quality field, although that doesn't always
follow), Tier IV the lowest. For each tier the WTA Tour
specifies a minimum level of prize-money to be awarded,
although there are a number of exceptions. The table
below lists the minimum prize-money available per grade
