Assets Held for Sale and Discontinuing Operations
Note 7 — Assets Held for Sale and Discontinued Operations
 
On December 31, 2013, the Company entered into a definitive asset purchase agreement with InfoMedia Services Limited (“Infomedia”), a private company, incorporated in the United Kingdom, for the sale of all assets (the “Asset Group”) and the assignment of all agreements related to the Company’s mobile social application business. The Asset Group, which the Company determined to represent a business in accordance with ASC 805, “Business Combinations,” is mostly comprised of the Company’s acquired technology (refer to Notes 5 and 6). The closing of the transaction, which was subject to the satisfaction or waiver of certain conditions, occurred on February 18, 2014 (“Closing”) (refer to Note 14). 
 
Upon Closing, in exchange for the assets and agreements related to the Company’s mobile social application business, the Company received 18 Class B shares of Infomedia, which represent an 8.25% ownership interest in Infomedia. The Infomedia Class B shares were accounted for as a cost-method investment in the first quarter of 2014. The Company will test its investment for impairment whenever events or changes in circumstances indicate that the carrying amount may no longer be recoverable.
 
In connection with the asset purchase agreement, an impairment loss of $7,253 was recorded during the fourth quarter of 2013, which represents the excess of the carrying value (which includes the portion of goodwill allocated to the mobile social application business) over the estimated fair value of the Asset Group. The fair value of the Asset Group was estimated using an income approach by developing a discounted, future, net cash flows model. The following table presents the carrying amounts of the major classes of assets from discontinued mobile social application in the Company’s consolidated balance sheet as of December 31, 2013 (as of December 31, 2013, there were no liabilities classified as held for sale, as no liabilities were transferred to Infomedia upon Closing):
