on May 8, 2002, and the name change became effective on May 22, 2002 On June 6, 2002, Yum! executed a two-for-one stock split. Shortly afterwards, due to Yum!'s lifetime contract with Pepsi, Long John Silver's and A&W Restaurants (which previously served Coca-Cola products) began switching to Pepsi products, with A&W Restaurants retaining A&W Root Beer from a separate deal with Dr Pepper/Seven Up (now Keurig Dr Pepper). In 2002, Yum! began testing co-branding locations pairing Pizza Hut with Pasta Bravo, Back Yard Burgers, and A&W. The Pasta Bravo concept was acquired in 2003 from Pasta Bravo, Inc. of Aliso Viejo, California for $5 million to pair with Pizza Hut. In 2003, Yum! launched WingStreet as a hybrid combo unit with an existing Pizza Hut franchise. In 2007 and 2008, a thousand WingStreet stores a year were opened. On October 19, 2009, Company president Scott Bergren publicized WingStreet's national launch. An East Dawning test cafeteria-style restaurant was opened in Shanghai in 2004. After initially failing, Yum! Brands chose the KFC business model (KFC is the most successful Western chain in China) and found greater success. As of September 30, 2007, eight East Dawning restaurants were in operation. International focus In January 2011, Yum! announced its intentions to divest itself of its Long John Silver's and A&W brands to focus on its core brands of KFC, Pizza Hut and Taco Bell. For the decade leading up to the company's announcement, major growth had relied on international expansion. With little presence outside North America, the two chains no longer fit in the company's long-term growth plans. The foreign expansion—particularly that of Taco Bell, KFC and Pizza Hut—was cited in the firm's January 18, 2011 announcement of its intention to sell the A&W and Long John Silver's chains. Both of those chains also suffered from poor sales, and had fewer locations compared to the other chains in the Yum! Brands portfolio. In September 2011, Yum! announced they had found buyers for the A&W and Long John Silver's chains. A Great American Brand will buy A&W, and Long John Silver's will be acquired by LJS Partners LLC. In May 2011, Yum! agreed to purchase Chinese hot pot chain Little Sheep for HK$4.56 billion. The deal spent more than 4 months in antitrust review by the Chinese Ministry of Commerce, to determine whether or not the transaction would result in a monopolistic positioning of Yum!
