Task: Question Generation
Input (English): Passage: In late 2008, Fortress Investments threatened to foreclose on Neverland Ranch, which Jackson had used as collateral for loans running into tens of millions of dollars. Fortress sold Jackson's debts to Colony Capital LLC. In November, Jackson transferred Neverland Ranch's title to Sycamore Valley Ranch Company LLC, a joint venture between Jackson and Colony Capital LLC. The deal earned him $35 million. Jackson arranged to sell a large collection of memorabilia through Julien's Auction House. The auction was scheduled to take place between April 22 and 25, 2009. An exhibition of the lots opened, but Jackson canceled the auction.In March 2009, at a press conference at London's O2 Arena, Jackson announced a series of comeback concerts titled This Is It, against a background of speculation about his finances and his health. The shows were to be his first major tour since the HIStory World Tour finished in 1997. Jackson suggested he would retire after the shows. The initial plan was for 10 concerts in London, followed by shows in Paris, New York City and Mumbai. Randy Phillips, president and chief executive of AEG Live, predicted that the first 10 dates would earn Jackson £50 million. The London residency was increased to 50 dates after record-breaking ticket sales: over one million were sold in less than two hours. The concerts were to run from July 13, 2009 to March 6, 2010. Jackson rehearsed in Los Angeles in the weeks leading up to the tour under the direction of choreographer Kenny Ortega. Most rehearsals took place at the Staples Center, owned by AEG.
