[1] All of the VIEs' assets can be used to settle obligations of their primary beneficiary. Liabilities recognized as a result of consolidating these VIEs do not represent additional claims on the Company's general assets (Note 2).

[2] In the fourth quarter of 2015, in order to obtain sufficient working capital to continue the expansion of the Company's core business, which is Internet advertising, precision marketing and the related technical and data services, the Company decided to sell its 51% equity interest in Beijing Chuang Fu Tia Xia, one of the Company's operating VIEs, which is primarily engaged in providing Internet advertising and marketing services through one of the Company's advertising portal, www.liansuo.com ("liansuo.com"). At the time when the Company committed a plan to sell liansuo.com, the Company did not consider the sale of liansuo.com is a strategic shift that had (or would have) a major effect on the Company's operations and financial results, as it was not a significant portion of the Company's Internet advertising and data service business segment, therefore, not qualifying for presentation as a discontinued operation. As a result, in accordance with ASC Topic 360: "Property, Plant and Equipment", the Company classified the assets and liabilities related to the disposal group as held for sale in the consolidated balance sheet as of December 31, 2015, but did not included its results of operations in discontinued operations. For financial reporting purpose, the Company reassesses the status of its assets and liabilities classified as held for sale on a quarterly basis in accordance with ASC Topic 360-10-45-9, basis on which, the Company concluded that its disposal group no longer met all the criterial for the classification as held for sale during the fourth quarter of 2016. Therefore, the Company reclassified the assets and liabilities related to the disposal group as held and use in accordance with ASC 360-10-35-44. The Company terminated its plan to sell liansuo.com in February 2017, subsequently.
