(“Ad-Icon Shanghai”), a wholly-owned subsidiary in China, which is permitted to operate advertising businesses in China. In 2010, Ad-Icon Shanghai, acquired 100% of the equity interests in Zhejiang Continental Advertising Co., Ltd. (“Zhejiang Continental”). In addition, 100% of the equity interests in five subsidiaries acquired by Jingli were transferred to Ad-Icon Shanghai during 2010 and 2011. Effective on December 23, 2011, the Company terminated the VIEs arrangements and ceased to consolidate the financial results of the VIE and its subsidiaries. The Company gradually disposed of certain of its wholly-owned subsidiaries prior to November 30, 2012. On December 31, 2012, the Company divested SearchMedia International and its subsidiaries to Partner Venture Holding Limited (“Partner”), an independent third party, to eliminate the remaining earn-out obligations and potential tax liabilities pursuant to the acquisition agreements with the subsidiaries of SearchMedia International. On August 15, 2012, the Company established Tiger Media Global Limited, a wholly-owned BVI subsidiary. On November 28, 2012, Tiger Media Global established Shanghai Tiger Shangda Management Consulting Co., Ltd. (“Tiger Shangda”). On November 30, 2012, 100% of the equity interest in Shanghai Tiger Yaoyang Advertising Co., Ltd. (“Tiger Yaoyang”) was transferred to Tiger Shangda. Tiger Yaoyang was incorporated on September 18, 2012, and started to operate the LCD advertising businesses in China in December 2012. On October 15, 2012, the Company established Tiger Media Investments Limited (“Tiger Media Investments”), a wholly-owned BVI subsidiary. On April 11, 2013, Tiger Media Investments established Tiger Media Limited, which was incorporated in Hong Kong to operate outdoor advertising business in Hong Kong. On March 21, 2014, Tiger Media Investments established Shanghai Tai Tian Advertising Co., Ltd. (“Shanghai Tai Tian”), which was incorporated in Shanghai Pilot Free Trade Zone. On March 21, 2015 (the “Effective Date”), Tiger Media and TBO Acquisition, LLC, a Delaware limited liability company and a direct wholly-owned subsidiary of Tiger Media established on December 11, 2014 (the “Merger Sub”), completed its previously announced merger (the “Merger”) with The Best One, Inc. (“TBO”), pursuant to the terms and conditions of the Merger Agreement and Plan of Reorganization, as amended (the “Merger Agreement”) dated as of December 14, 2014, by and among Tiger Media, Merger Sub, TBO and Derek Dubner, solely in his capacity as representative of the TBO shareholders. Before the Merger, on October 2, 2014, TBO acquired 100% of the membership interests of Interactive Data, LLC, a Georgia limited liability company (“Interactive Data”), a data solutions provider. The Merger was consummated effective as of March 21, 2015. Prior to the Merger, on March 20, 2015, Tiger Media completed its domestication from the Cayman Islands to Delaware, as a Delaware Corporation (“Domestication”). As a result of the Domestication, Tiger Media no longer qualifies as a “foreign private issuer” as that term is defined under the U.S. Federal securities laws. As such, Tiger Media will now file reports as a U.S. domestic reporting company under the U.S. Securities laws
