Fed Cup by BNP Paribas is the women's premier international team tennis event. The event is one of the cornerstones of the tennis calendar. This prestigious event gives players the chance to represent their country in an otherwise individual sport. Fed Cup is structured with an eight-nation World Group and eight-nation World Group II, contested over three weekends during the year. The remaining countries are then divided into three regional zones depending on their location. The competition is managed and run by the International Tennis Federation (ITF). Fed Cup is the world's largest annual international team competition and the World Cup of Tennis in Women Sports.
