WTA Premier Mandatory

In 2009, the old structure of the WTA Tour was replaced by a new one and new Premier tournaments replaced the previous Tier I and Tier II categories. The main changes were a decrease in the duration of the playing season and a 40 percent increase in prize money. In the new structure, the most prestigious became four Premier Mandatory events. The winners of these tournaments are awarded 1000 rankings points.
