The women's event is a $2 million Premier 5 event on the Sony Ericsson WTA Tour and is the only Sony Ericsson WTA Tour event held in the American Midwest. In 2010, the men's and women's events will be played in back-to-back weeks in August (August 7–22) but in 2011 both tournaments will be played in a single eight-day span. Because of its sponsorship by the Western & Southern Financial Group, the official name of the event is the Western & Southern Financial Group Masters & Women's Open.
