The tournament was played in its final playoff form for the first time in November 2006; the champion of the event, Julieta Granada, won $1 million, the highest first-place prize in the history of women's golf.
[1] Another entirely new tournament,[2] the LPGA Tour Championship, took ADT's place on the LPGA schedule for two years in 2009 and 2010; it was succeeded by the CME Group Titleholders in 2011 As in the two previous seasons, the 2008 season was split into two halves, with 15 players from each half qualifying for the ADT Championship using a performance-based points system.
The two wild cards were the top two players from the LPGA Official Money List who were not otherwise qualified after the Lorena Ochoa Invitational: Sun Young Yoo and Christina Kim.
The first half began with the SBS Open at Turtle Bay and ended with the Jamie Farr Owens Corning Classic.
The top 15 points scorers and one wild card from each half qualified for the Playoffs, making for a total of 32 players who will take part in the season-ending event.
In addition, all winners of the LPGA's majors and five limited field events, such as the HSBC Women's World Match Play Championship, automatically qualified for the Playoffs.
On November 21, 2009, Golf Channel's Randall Mell reported in a blog post that the LPGA was in preliminary discussions to bring back the tournament in 2011.
