[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 focus all the Company's resources on its core business, which is Internet advertising, marketing and the related technical and data services, and to obtain sufficient working capital to continue the expansion of the services distribution channels and to support the development of the 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"). The Company does not consider the sale of liansuo.com is a strategic shift that has (or will have) a major effect on the Company's operations and financial results, as it is not a significant portion of the Company's Internet advertising 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 andliabilities related to the disposal group as held for sale in the consolidated balance sheets as of December 31, 2015 but did not included its results of operations in discontinued operations for all period presented.
