Some of these are styled as "resort" properties, and may have spas or other recreational facilities. One of the first of these was the Hyatt Regency Maui in 1980. In June 2004, substantially all of the hospitality assets owned by Pritzker family business interests, including Hyatt Corporation and Hyatt International Corporation, were consolidated under a single entity called Global Hyatt Corp. On June 30, 2009, Global Hyatt Corporation changed its name to Hyatt Hotels Corporation. In December 2004, Hyatt Hotels Corporation acquired AmeriSuites, an upscale chain of all-suite business class hotels from affiliates of the Blackstone Group, a New York-based private equity investment firm. Blackstone had inherited AmeriSuites from its 2004 acquisition of Prime Hospitality. The AmeriSuites chain was rebranded and called Hyatt Place, a competitor to the limited-service products Marriott International's Courtyard by Marriott and Hilton Worldwide's Hilton Garden Inn. In December 2005, Hyatt acquired limited service company Summerfield Suites from the Blackstone Group. Blackstone had inherited Summerfield Suites from its purchase of Wyndham International. In January 2012, Hyatt Summerfield Suites were rebranded as Hyatt House in 2012 to compete in the "upscale extended stay market" against Residence Inn, Homewood Suites, and Staybridge Suites. Hyatt launched the Andaz brand in April 2007. The first Andaz hotel was the Great Eastern Hotel in London, followed by hotels in San Diego, West Hollywood, Shanghai and New York City (Andaz Wall Street & Andaz 5th Avenue). In August 2009, it was reported that Hyatt Hotels Corporation filed plans to raise up to $1.15 billion in an initial share sale. That November Hyatt completed an initial public offering and began trading publicly on the New York Stock Exchange under the symbol "H." According to the filing Mark S. Hoplamazian was to serve as CEO and Thomas Pritzker as Executive Chairman. The public offering was a result of the acrimonious breakup of the Pritzker family empire. Accused of looting family trusts, Thomas and cousins Penny and Nicholas took control of the family businesses when they and other family members were sued by cousin Liesel Pritzker, claiming fraud and seeking damages of over US$6 billion. On September 1, 2011, Hyatt acquired Hotel Sierra, which had 18 properties in 10 states. Along with Hyatt Summerfield Suites hotels, several of these properties were rebranded as Hyatt house in January 2012.
