In 2007 and 2008, it was the final "winner" event of the LPGA season—i.e., an event in which the winner earns an automatic berth in the LPGA season-ending championship, the LPGA Tour Championship. As of 2009, the LPGA no longer uses this system to determine players who qualify for the Tour Championship. From 2007 to 2009, the CWO was the third richest event on the LPGA Tour, behind only the U.S. Women's Open and the Evian Masters in France. The prize fund was reduced in 2010 and 2012, but the $2.25 million purse remains among the highest on the LPGA Tour.
