| The Company and Nature of Operations |
Nature of Operations and Organization Sohu.com Limited was incorporated in the Cayman Islands on May 30, 2003 as a direct wholly-owned subsidiary of Sohu.com Inc., which was incorporated in Delaware in August 1996 and was the ultimate parent company of the Sohu Group (as defined below) until its dissolution on May 31, 2018. On July 17, 2000, Sohu.com Inc. completed an initial public offering (“IPO”) of shares of its common stock on NASDAQ trading under the symbol “SOHU.” On May 31, 2018, pursuant to a proposal for the dissolution of Sohu.com Inc. and adoption of a plan of complete liquidation and dissolution of Sohu.com Inc. that was approved by the stockholders of Sohu.com Inc. at a special meeting of stockholders held on May 29, 2018, Sohu.com Inc. was dissolved, all outstanding shares of the common stock of Sohu.com Inc. were delisted and cancelled, and ADSs representing all outstanding ordinary shares of Sohu.com Limited were distributed on a share-for-share basis to the stockholders of Sohu.com Inc. On June 1, 2018 Sohu.com Limited’s ADSs began trading on the NASDAQ Global Select Market under the same “SOHU” symbol in place of the common stock of Sohu.com Inc. As a result, Sohu.com Limited replaced Sohu.com Inc. as the top-tier, publicly-traded holding company of the Sohu Group (as defined below). Sohu.com Limited (or its predecessor Sohu.com Inc., as applicable), together with its subsidiaries and consolidated VIEs, are collectively referred to herein as the “Sohu Group,” the “Group” or the “Company.” The Sohu Group is a leading Chinese online media, search and game service group providing comprehensive online products and services on PCs and mobile devices in China. The Sohu Group, which consists of “Sohu,” which when referred to in this report, unless the context requires otherwise, excludes the businesses and the corresponding subsidiaries and VIEs of Sogou Inc. (“Sogou”) and Changyou.com Limited (“Changyou”), Sogou and Changyou. Sogou and Changyou are the indirect controlled subsidiaries of the Company. Sohu is a leading Chinese language online media content and services provider; Sogou is an innovator in search and a leader in China’s Internet industry; and Changyou is a leading online game developer and operator in China that engages primarily in the development, operation and licensing of online games for PCs and mobile devices. Most of the Sohu Group’s operations are conducted through the Group’s China-based subsidiaries and VIEs. Sogou completed its IPO on the NYSE in November 2017 trading under the symbol “SOGO.” Changyou completed its IPO on NASDAQ in April 2009, trading under the symbol “CYOU.” As Sohu.com Limited, or its predecessor Sohu.com Inc., is the controlling shareholder of both Sogou and Changyou, Sohu.com Limited consolidates Sogou and Changyou in its consolidated financial statements, and recognizes noncontrolling interests reflecting economic interests in Sogou and Changyou held by shareholders other than Sohu.com Limited. The consolidated financial statements of Sohu.com Limited represent the continuation of the financial statements of Sohu.com Inc., reflecting the assets and liabilities, accumulated deficit and other equity balances of Sohu.com Inc. immediately before Sohu.com Inc.’s dissolution on May 31, 2018. Through the operation of Sohu, Sogou and Changyou, the Sohu Group generates online advertising revenues, including brand advertising revenues and search and search-related advertising revenues; online games revenues; and other revenues. Online advertising and online games are the Sohu Group’s core businesses. The principal subsidiaries and VIEs through which the Group conducts its business operations as of December 31, 2018 are described below:
Sohu’s Business Brand Advertising Business Sohu’s main business is the brand advertising business, which offers to users, over Sohu’s matrices of Chinese language online media, various content, products and services across multiple Internet-enabled devices such as PCs, mobile phones and tablets.

Revenues generated by the brand advertising business are classified as brand advertising revenues in the Sohu Group’s consolidated statements of comprehensive income. Other Sohu Business Sohu also engages in the other business, which consists primarily of paid subscription services, interactive broadcasting services, and content provided through the platforms of the three main telecommunications operators in China. Revenues generated by Sohu from the other business are classified as other revenues in the Sohu Group’s consolidated statements of comprehensive income.
Sogou’s Business Search and Search-related Business The search and search-related business consists primarily of search and search-related advertising services offered by Sogou. Search and search-related advertising services enable advertisers’ promotional links to be displayed on Sogou’s search results pages and other Internet properties and third parties’ Internet properties where the links are relevant to the subject and content of searches and such properties. Sogou’s advertising services expand distribution of advertisers’ promotional links and advertisements by leveraging traffic on third parties’ Internet properties, including Web content, software, and mobile applications. The search and search-related business also benefits from Sogou’s collaboration with Tencent Holdings Limited (together with its subsidiaries, “Tencent”), which provides Sogou access to traffic and content generated from products and services provided by Tencent. Revenues generated by the search and search-related business are classified as search and search-related advertising revenues in the Sohu Group’s consolidated statements of comprehensive income. Other Sogou Business Sogou also offers IVAS, primarily with respect to the operation of Web games and mobile games developed by third parties and the provision of online reading services, and offers other products and services, including smart hardware products. Revenues generated by Sogou from other business are classified as other revenues in the Sohu Group’s consolidated statements of comprehensive income. Initial Public Offering of Sogou On November 13, 2017, Sogou completed its IPO on the NYSE, trading under the symbol “SOGO.” Sogou’s Ordinary Shares are divided into Sogou Class A Ordinary Shares and Sogou Class B Ordinary Shares. Holders of Sogou Class A Ordinary Shares and holders of Sogou Class B Ordinary Shares have identical rights with the exception of voting and conversion rights. Each Sogou Class A Ordinary Share is entitled to one vote per share and is not convertible. Each Sogou Class B Ordinary Share is entitled to ten votes per share and is convertible into one Sogou Class A Ordinary Share at any time. Sogou issued and sold in its IPO 50,643,856 Sogou Class A Ordinary Shares represented by 50,643,856 ADSs, including 5,643,856 Sogou Class A Ordinary Shares represented by 5,643,856 ADSs sold pursuant to the exercise of the underwriters’ over-allotment option. Proceeds to Sogou from the IPO were approximately $622.1 million, after deducting underwriting discounts and commissions and offering expenses. Following the completion of Sogou’s IPO, pursuant to the Voting Agreement among Sohu, Tencent, and Sogou (the “Voting Agreement”) that took effect upon the completion of Sogou’s IPO, Sohu has the right to appoint a majority of Sogou’s Board of Directors, and Sohu continues to consolidate Sogou in Sohu’s financial statements and provide for noncontrolling interests reflecting ordinary shares in Sogou held by shareholders other than Sohu. In the fourth quarter of 2017, Sohu recognized a one-time credit to additional paid-in capital of $278.4 million in shareholders’ equity in Sohu’s consolidated balance sheets to reflect the increase in the value of Sohu’s equity in Sogou that resulted from the completion of Sogou’s IPO. Voting Agreement between Sohu, Tencent and Sogou Pursuant to the Voting Agreement, Sohu and Tencent agreed that, subject to certain exceptions, (1) within three years following the completion of Sogou’s IPO, Sohu will vote all Sogou Class B Ordinary Shares and any Sogou Class A Ordinary Shares held by it and Tencent will vote 45,578,896 of its Sogou Class B Ordinary Shares to elect a Board of Directors consisting of seven directors, four of whom will be appointed by Sohu, two of whom will be appointed by Tencent, and the seventh of whom will be Sogou’s then chief executive officer, and (2) after three years following the completion of Sogou’s IPO, Sohu will be entitled to choose to change the size and composition of Sogou’s Board of Directors, subject to Tencent’s right to appoint at least one director. The effect of these provisions is to give Sohu the power to appoint a majority of Sogou’s Board of Directors, and to give Tencent the power to appoint two directors within three years following the completion of Sogou’s IPO and at least one director after three years after the completion of Sogou’s IPO. The Voting Agreement also provides that, subject to certain conditions, for so long as Sohu and Tencent together hold more than 50% of the total voting power of the Sogou Class A Ordinary Shares and the Sogou Class B Ordinary Shares, Sohu or Tencent may remove and replace any director appointed by it. These provisions of the Voting Agreement are also reflected in Sogou’s Amended and Restated Memorandum of Association and Amended and Restated Articles of Association. Due to the additional voting power of the Sogou Class B Ordinary Shares held by Sohu and Tencent, as of the date of this report Sohu holds approximately 33% of the total of Sogou’s outstanding Class A and Class B Ordinary Shares and controls approximately 44% of the total voting power of the combined total of Sogou’s outstanding Class A and Class B Ordinary Shares; Tencent has an indirect shareholding of approximately 38% of the total of Sogou’s outstanding Class A and Class B Ordinary Shares and controls approximately 52% of the total voting power of the combined total of Sogou’s outstanding Class A and Class B Ordinary Shares; and Sohu and Tencent together have the power to decide all matters that may be brought to a vote of Sogou’s shareholders. The Voting Agreement and Sogou’s Amended and Restated Articles of Association also specify that for so long as Sohu or Tencent holds not less than 15% of Sogou’s issued shares (calculated on a fully diluted basis), consent from the holder of 15% or more (either or both of Sohu or Tencent, as the case may be) will be required (1) to amend Sogou’s Amended and Restated Memorandum of Association or Amended and Restated Articles of Association, (2) to make material changes in Sogou’s principal lines of business, (3) to issue any additional Sogou Class B Ordinary Shares, (4) to create any new class or series of shares that is pari passu with or senior to the Sogou Class A Ordinary Shares, (5) for Sogou to approve a liquidation, dissolution or winding up of Sogou, or a merger or consolidation resulting in a change in control, or any disposition of all or substantially all of Sogou’s assets, or (6) for Sogou to enter into any transactions with affiliates of Sohu, other than in the ordinary course of business. Of these corporate actions that are subject to consent of Sohu or Tencent (as applicable), shareholder approval is required under the Companies Law of the Cayman Islands for any amendment of Sogou’s Amended and Restated Memorandum of Association or Amended and Restated Articles of Association, any winding-up of Sogou Inc., or any merger or consolidation with a third-party entity. The Voting Agreement and Sogou’s Amended and Restated Articles of Association further provide that if Sogou’s shareholders have voted in favor of any of these actions requiring the approval of Sogou’s shareholders but consent from Sohu or Tencent (as applicable) has not been obtained, then the holders of all classes of Sogou’s shares who have voted against such action will be deemed to have such number of votes as are equal to the aggregate number of votes cast in favor of such actions plus one additional vote. Under these provisions of the Voting Agreement and Sogou’s Amended and Restated Articles of Association, if an action is proposed for which the consent of either Tencent or Sohu is required, the failure to obtain the consent of Tencent or Sohu will have the effect of the proposed action’s not being approved, even if Sogou’s other shareholders approve it. The Voting Agreement and Sogou’s Amended and Restated Articles of Association also specify that if at any time Sohu alone holds more than 50% of the total voting power of the Sogou Class A Ordinary Shares and the Sogou Class B Ordinary Shares, the voting arrangements with respect to the size and composition of Sogou’s Board of Directors will be automatically suspended until such time within five years after the completion of Sogou’s IPO as Sohu’s voting power again drops to 50% or less, in which case the original voting arrangements will be reinstated, provided that Tencent will only be required to vote the lower of 45,578,896 Sogou Class B Ordinary Shares held by it or such number as would give Sohu combined voting power of 50.1%. If such a suspension continues after the fifth anniversary of the completion of Sogou’s IPO, the voting arrangements with respect to the size and composition of Sogou’s Board of Directors will terminate. All of the Sogou Class B Ordinary Shares held by Sohu will be converted into Sogou Class A Ordinary Shares if there is a transaction resulting in change of control of Sohu that was not approved by Sohu’s board of directors, if specified competitors of Tencent control Sohu, or if a majority of Sohu’s board of directors consist of nominees of specified competitors of Tencent. The provisions with respect to the size and composition of Sogou’s Board of Directors set out in the Voting Agreement and Sogou’s Amended and Restated Articles of Association will terminate upon occurrence of any such event. Such arrangements will also terminate (1) if Dr. Charles Zhang, the chairman of the board of directors of Sohu and the chief executive officer, both ceases being the chairman of the board of directors of Sohu and ceases being the single largest beneficial owner of Sohu’s outstanding shares; (2) if Sohu transfers 30% or more of the Sogou Class B Ordinary Shares that Sohu held upon the completion of Sogou’s IPO; (3) if Sogou fails to provide irrevocable instructions to the person maintaining Sogou’s register of members to accept instructions from Tencent, under certain circumstances, with respect to the conversion of Sogou Class B Ordinary Shares held by Sohu; (4) or Sogou changes, without Tencent’s consent, the person that maintains Sogou’s register of members; (5) or if Tencent ceases to own any Sogou Class B Ordinary Shares. Under the Voting Agreement, Sohu and Tencent are subject to certain restrictions on transfer of their Sogou Class A and Class B Ordinary Shares. In particular, a transfer of Sogou Class B Ordinary Shares by either Sohu or Tencent, respectively, to any person or entity that is not a direct or indirect wholly-owned subsidiary of Sohu or Tencent, respectively, will cause such Sogou Class B Ordinary Shares to be converted into Sogou Class A Ordinary Shares. Voting Agreement between Sohu, Photon and Sogou Management Sohu may be deemed to have beneficial ownership attributable to shared voting power of Sogou Class A Ordinary Shares beneficially owned by Photon Group Limited (“Photon”), an investment vehicle of the Company’s Chairman and Chief Executive Officer Charles Zhang, Sogou’s chief executive officer Xiaochuan Wang, and certain other members of the Sogou management, as a result of a voting agreement by and among Sohu, Photon, Mr. Wang and the other members of Sogou management, pursuant to which Photon, Mr. Wang, and the other members of Sogou Management have agreed to vote their Sogou Class A Ordinary Shares (not including shares acquired by Mr. Wang in the public market following Sogou’s IPO) to elect Sohu’s designees to Sogou’s Board of Directors. Sogou’s Share Structure As of December 31, 2018, Sogou had a combined total of 397,158,375 Sogou Class A Ordinary Shares and Sogou Class B Ordinary Shares issued and outstanding, consisting of:
The total number of Sogou outstanding shares listed above include 5,805,000 Sogou Class A Ordinary Shares that are outstanding for legal purposes, but have been determined to be Sogou treasury stock for accounting purposes. Changyou’s Business Changyou’s business lines consist of the online game business; the platform channel business, which consists primarily of online advertising and IVAS; and the cinema advertising business. Online Game Business Changyou’s online game business offers PC games and mobile games to game players. All of Changyou’s games are operated under the item-based revenue model, meaning that game players can play the games for free, but may choose to pay for virtual items, which are non-physical items that game players can purchase and use within a game, such as gems, pets, fashion items, magic medicine, riding animals, hierograms, skill books and fireworks. Revenues derived from the operation of online games are classified as online game revenues in the Sohu Group’s consolidated statements of comprehensive income. PC Games PC games are interactive online games that are accessed and played simultaneously by hundreds of thousands of game players through personal computers and require that local client-end game access software be installed on the computers used. Changyou’s dominant game is Tian Long Ba Bu (“TLBB”), a PC based client-end game. For the year ended December 31, 2018, revenues from TLBB were $200.9 million, accounting for approximately 52% of Changyou’s online game revenues, approximately 41% of Changyou’s total revenues and approximately 11% of the Sohu Group’s total revenues. Mobile Games Mobile games are played on mobile devices and require an Internet connection. In the second quarter of 2017, Changyou launched a new mobile game, Legacy TLBB (“Legacy TLBB Mobile”), which is operated by Tencent under license from Changyou. For the year ended December 31, 2018, revenues from Legacy TLBB Mobile were $102.6 million, accounting for approximately 26% of Changyou’s online game revenues, approximately 21% of Changyou’s total revenues, and approximately 5% of the Sohu Group’s total revenues. Platform Channel Business Changyou’s platform channel business consists primarily of the operation of the 17173.com Website and RaidCall. Prior to Changyou’s sale of MoboTap Inc. (“MoboTap”) in March 2018, Changyou’s platform channel business also included MoboTap. 17173.com Website The 17173.com Website provides news, electronic forums, online videos and other information services regarding online games to game players in China. All revenues generated by the 17173.com Website are classified as brand advertising revenues. RaidCall RaidCall provides online music and entertainment services, primarily in Taiwan. IVAS revenues generated by RaidCall are classified as other revenues in the Sohu Group’s consolidated statements of comprehensive income.

Revenues generated by Changyou’s cinema advertising business are classified as other revenues in the Sohu Group’s consolidated statements of comprehensive income. Changyou’s Share Structure As of December 31, 2018, Changyou had a combined total of 106,501,420 Changyou Class A and Class B Ordinary Shares issued and outstanding, consisting of:

| Summary of Significant Accounting Policies |
Accounting Standards The consolidated financial statements have been prepared in accordance with United States of America generally accepted accounting principles (“U.S. GAAP”) to reflect the financial position and results of operations of the Sohu Group. Use of Estimates The preparation of these financial statements requires the Sohu Group to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues, costs and expenses, and related disclosures. On an on-going basis, the Group evaluates its estimates based on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. Identified below are the accounting policies that reflect the Group’s most significant estimates and judgments, and those that the Group believes are the most critical to fully understanding and evaluating its consolidated financial statements. Basis of Consolidation and Recognition of Noncontrolling Interest The Sohu Group’s consolidated financial statements include the accounts of the Company and its subsidiaries and consolidated VIEs. All intra-Group transactions are eliminated. VIE Consolidation The Sohu Group’s VIEs are wholly or partially owned by certain employees of the Group as nominee shareholders. For consolidated VIEs, management made evaluations of the relationships between the Sohu Group and the VIEs and the economic benefit flow of contractual arrangements with the VIEs. In connection with such evaluation, management also took into account the fact that, as a result of such contractual arrangements, the Group controls the shareholders’ voting interests in these VIEs. As a result of such evaluation, management concluded that the Sohu Group is the primary beneficiary of its consolidated VIEs. Noncontrolling Interest Recognition Noncontrolling interests are recognized to reflect the portion of the equity of subsidiaries and VIEs which is not attributable, directly or indirectly, to the controlling shareholders. Currently, the noncontrolling interests in the Sohu Group’s consolidated financial statements primarily consist of noncontrolling interests for Sogou and Changyou. Noncontrolling Interest for Sogou Prior to the completion of Sogou’s IPO in November 2017, the Company controlled the election of a majority of the Board of Directors of Sogou pursuant to a shareholders’ agreement that expired upon completion of the IPO. Following the completion of Sogou’s IPO, pursuant to the Voting Agreement and Sogou’s Third Amended and Restated Articles of Association, the Company still has the right to appoint a majority of Sogou’s Board of Directors. As Sogou’s controlling shareholder, the Company consolidates Sogou in its consolidated financial statements, and recognizes noncontrolling interest reflecting economic interests in Sogou held by shareholders other than it (the “Sogou noncontrolling shareholders”). Sogou’s net income /(loss) attributable to the Sogou noncontrolling shareholders is recorded as noncontrolling interest in its consolidated statements of comprehensive income. Noncontrolling Interest Recognition before Sogou’s IPO Based on the principles of allocation of Sogou’s profit and loss set forth below, Sogou’s cumulative results of operations attributable to the Sogou noncontrolling shareholders, along with changes in shareholders’ equity/(deficit) and adjustments for share-based compensation expense in relation to those share-based awards that were unvested and vested but not yet settled and the Sogou noncontrolling shareholders’ investments in Sogou Series A Preferred Shares outstanding before Sogou’s IPO (“Sogou Pre-IPO Series A Preferred Shares”) and Sogou Series B Preferred Shares outstanding before Sogou’s IPO (“Sogou Pre-IPO Series B Preferred Shares”) (together, the “Sogou Pre-IPO Preferred Shares”) and Sogou ordinary shares outstanding before Sogou’s IPO (“Sogou Pre-IPO Class A Ordinary Shares” and “Sogou Pre-IPO Class B Ordinary Shares, as applicable) were accounted for as a noncontrolling interest classified as permanent equity in the Sohu Group’s consolidated balance sheets, as Sohu Group had the power to reject a redemption requested by the noncontrolling shareholders. These treatments were based on the terms governing investment, and on the terms of the classes of Sogou shares held, by the noncontrolling shareholders in Sogou before Sogou’s IPO. Principles of Allocation of Sogou’s Profit and Loss - By virtue of the terms of the Sogou Pre-IPO Preferred Shares, Pre-IPO Class A Ordinary Shares, and Pre-IPO Class B Ordinary Shares, Sogou’s losses were allocated in the following order before Sogou’s IPO: (i) net losses were allocated to holders of the Sogou Pre-IPO Class A Ordinary Shares and the holder of the Sogou Pre-IPO Class B Ordinary Shares until their basis in Sogou decreased to zero; (ii) additional net losses were allocated to holders of the Sogou Pre-IPO Series A Preferred Shares until their basis in Sogou decreased to zero; (iii) additional net losses were allocated to the holder of the Sogou Pre-IPO Series B Preferred Shares until its basis in Sogou decreased to zero; and (iv) further net losses were allocated between Sohu and noncontrolling shareholders based on their shareholding percentage in Sogou. Net income from Sogou was allocated in the following order before Sogou’s IPO: (i) net income was allocated between Sohu and noncontrolling shareholders based on their shareholding percentage in Sogou until their basis in Sogou increased to zero; (ii) additional net income was allocated to the holder of the Sogou Pre-IPO Series B Preferred Shares to bring its basis back; (iii) additional net income was allocated to holders of the Sogou Pre-IPO Series A Preferred Shares to bring their basis back; (iv) further net income was allocated to holders of the Sogou Pre-IPO Class A Ordinary Shares and the holder of the Sogou Pre-IPO Class B Ordinary Shares to bring their basis back; and (v) further net income was allocated between Sohu and noncontrolling shareholders based on their shareholding percentage in Sogou. Noncontrolling Interest Recognition after Sogou’s IPO Sogou’s cumulative results of operations attributable to the Sogou noncontrolling shareholders, based on their share of the economic interest in Sogou, along with changes in shareholders’ equity and adjustment for share-based compensation expense in relation to share-based awards that are unvested and vested but not yet settled and adjustment for changes in the Sohu Group’s ownership percentage in Sogou, are recorded as noncontrolling interest in the Sohu Group’s consolidated balance sheets. Noncontrolling Interest for Changyou As of the date of this report, Sohu holds approximately 67% of the combined total of Changyou’s outstanding ordinary shares, and controls approximately 95% of the total voting power in Changyou.
As Changyou’s controlling shareholder, Sohu consolidates Changyou in its consolidated financial statements, and recognizes noncontrolling interest reflecting the economic interest in Changyou held by shareholders other than the Company (the “Changyou noncontrolling shareholders”). Changyou’s net income /(loss) attributable to the Changyou noncontrolling shareholders is recorded as noncontrolling interest in the Sohu Group’s consolidated statements of comprehensive income, based on the noncontrolling shareholders’ share of the economic interest in Changyou. Changyou’s cumulative results of operations attributable to the Changyou noncontrolling shareholders, along with changes in shareholders’ equity, adjustment for share-based compensation expense in relation to those share-based awards which are unvested and vested but not yet settled and adjustment for changes in the Company’s ownership in Changyou, are recorded as noncontrolling interest in the Sohu Group’s consolidated balance sheets. Segment Reporting The Sohu Group’s segments are business units that offer different services and are reviewed separately by the chief operating decision maker (the “CODM”), or the decision making group, in deciding how to allocate resources and in assessing performance. The Group’s CODM is the Company’s Chief Executive Officer. Revenue Recognition Impact of Adoption of ASC 606 On January 1, 2018, the Sohu Group adopted ASC 606, applying the modified retrospective method to contracts that were not completed as of January 1, 2018. The adoption of ASC 606 did not have a material impact on the Company’s accumulated deficit as of January 1, 2018. Results for reporting periods beginning on or after January 1, 2018 are presented under ASC 606, while prior-period amounts are not adjusted and continue to be reported in accordance with the Group’s historic accounting under ASC 605. Under ASC 605, advertising-for-advertising barter transactions for which the fair value of the advertising services was not determinable were recorded at the carrying amount of the advertising surrendered, since the Group did not settle such barter transactions with the counterparties in cash. As ASC 605 has been superseded by ASC 606 on this subject, advertising-for-advertising barter transactions are to be recorded at the fair value of the advertising received by reference to the fair value of advertising services provided to other customers. The impact for the year of 2018 was an increase of approximately $25.6 million in revenues, with corresponding increases in cost of revenues and sales and marketing expenses, most of which were generated from Sogou for services provided to and received from Tencent. To a lesser extent, there is a potential impact on the Group’s accounting for exchanges of brand advertising placements with other platforms by Sohu. Revenues are recognized in the same amount as the corresponding costs and expenses. Therefore, there was no net profit and loss impact to the Group for the year of 2018. The following table illustrates the effect of the adoption of ASC 606 by presenting a comparison of selected line items from the Group’s consolidated statement of comprehensive income for the year ended December 31, 2018, as actually reported and as they would have been reported under ASC 605 without the adoption of ASC 606 (in thousands, except per share data):
The adoption of ASC 606 did not change the Group’s consolidated balance sheet, consolidated statement of cash flows, or consolidated statement of changes in equity as of, or for the year ended, December 31, 2018. Revenues are recognized when control of the promised goods or services is transferred to the Group’s customers, in an amount that reflects the consideration the Group expects to be entitled to in exchange for those goods or services. The recognition of revenues involves certain management judgments, including estimated lives of virtual items purchased by game players, the estimation of the fair value of an advertising-for-advertising barter transaction, allocation of upfront license fees for licensed-out games between license and post-sale services, and volume sales rebates. The Group does not believe that significant management judgements are involved in revenue recognition, but the amount and timing of the Group’s revenues could be different for any period if management made different judgments or utilized different estimates. The following table presents the Group’s revenues disaggregated by products and services:
As noted above, in accordance with the modified retrospective method upon adoption of ASC 606, prior-period amounts were not adjusted. Online Advertising Revenues Online advertising revenues include revenues from brand advertising services as well as search and search-related advertising services. Certain customers may receive sales rebates, which are accounted for as variable consideration. The Group estimates annual the expected revenue volume from each agent with reference to its historical results. Sales rebates will reduce revenues recognized. The Group recognizes revenue for the amount of fees it receives from its advertisers, after deducting sales rebates and net of value-added tax (“VAT”). The Group believes that there will not be significant changes to its estimates of variable consideration. Brand Advertising Revenues Revenue Recognition of Multiple Performance Obligations The Group’s contracts with customers may include multiple performance obligations. For such arrangements, the Group allocates revenues to each performance obligation based on its relative standalone selling price. The Group generally determines the standalone selling price of each distinct performance obligation based on the prices charged to customers when sold on a standalone basis. Where a standalone selling price is not directly observable, the Group generally estimates the selling price based on the prices at which performance obligations of a similar nature and geography are charged to customers. Most of such contracts have all performance obligations completed within the same quarter.
Pricing Model Through PCs and mobile devices, the Group provides advertisement placements to its advertisers on different Internet platforms and in different formats, which include banners, links, logos, buttons, full screen, pre-roll, mid-roll, post-roll video screens, pause video screens, loading page ads, news feed ads and in-feed video infomercial ads. Currently the Group has three main types of pricing models, consisting of the Fixed Price model, the Cost Per Impression (“CPM”) model and the Cost Per click (“CPC”) model.
Under the Fixed Price model, a contract is signed to establish a fixed price for the advertising services to be provided. Given that the advertisers benefit from displayed advertisements evenly over the period the advertisements are displayed, the Group recognizes revenue on a straight-line basis over the period of display, provided all revenue recognition criteria have been met.
Under the CPM model, the unit price for each qualifying display is fixed and stated in the contract with the advertiser. A qualifying display is defined as the appearance of an advertisement, where the advertisement meets criteria specified in the contract. Given that the fees are priced consistently throughout the contract and the unit prices are fixed in accordance with the Group’s pricing practices for similar advertisers, the Group recognizes revenue based on the fixed unit prices and the number of qualifying displays upon their occurrence, provided all revenue recognition criteria have been met.
Under the CPC model, there is no fixed price for advertising services stated in the contract with the advertiser and the unit price for each click is auction-based. The Group charges advertisers on a per-click basis, when the users click on the advertisements. Given that the fees are priced consistently throughout the contract and the unit prices are fixed in accordance with the Group’s pricing practices for similar advertisers, the Group recognizes revenue based on qualifying clicks and unit price upon the occurrence of the clicks, provided all revenue recognition criteria have been met. Search and Search-related Advertising Revenues Search and search-related services consist primarily of search and search-related advertising services offered by Sogou. Pay-for-click Services Pay for click services enable advertisers’ promotional links to be displayed on Sogou search result pages and other Internet properties and third parties’ Internet properties where the links are relevant to the subject and content of searches and such properties. For pay for click services, Sogou introduces Internet users to its advertisers through auction-based systems and charges advertisers on a per-click basis when the users click on the displayed links. The performance obligation of pay-for-click services is satisfied at the point in time when the user clicks on the displayed links, and revenue for pay-for-click services is recognized on a per-click basis. Other Online Advertising Services Other online advertising services mainly consist of displaying advertisers’ promotional links on Sogou’s Internet properties. For time-based advertising services, the Sogou’s performance obligation is satisfied over time when the advertising links are displayed over the contract periods, and revenue is normally recognized on a straight-line basis over the contracted display period. For performance-based advertising services, for example, advertisers are charged based on the times that users download from the displayed links, Sogou’s performance obligation is satisfied at the point in time when the promised performance is completed, and the revenue is recognized upon the completion of the promised performance. Sogou’s online advertising services expand distribution of advertisers’ promotional links and advertisements by leveraging traffic on third parties’ Internet properties, including Web content, software, and mobile applications. Sogou is the principal in such arrangement because its promise to advertisers is to provide the advertising services itself rather than to arrange for the advertising services to be provided by third parties on their Internet properties. Payments made to operators of third-party Internet properties are included in traffic acquisition costs.
Online Game Revenues Changyou’s online game revenues are generated primarily from its self-operated and licensed-out PC games and mobile games. All of Changyou’s games are operated under the item-based revenue model, where the basic game play functions are free of charge and players are charged for purchases of in-game virtual items, including those with a predetermined expiration time and perpetual virtual items. Changyou is the principal of its self-operated games. Changyou hosts the games on its own servers and is responsible for the sale and marketing of the games as well as customer service. Accordingly, revenues are recorded gross of revenue sharing-payments to third-party developers and/or mobile APP stores, but net of VAT and discounts to game card distributors where applicable. Changyou obtains revenues from the sale of in-game virtual items. Revenues are recognized as the virtual items are consumed or over the estimated lives of the virtual items, which are estimated by considering the average period that paying players typically play Changyou’s games and other player behavior patterns derived from operating data. If different assumptions were used in deriving the estimated lives of the virtual items, the timing of the recording of the revenues could be impacted. PC Games Proceeds from Changyou’s self-operated PC games are collected from players and third-party game card distributors through sales of Changyou’s game points on its online payment platform and prepaid game cards. Changyou’s self-operated PC games are either developed in house or licensed from third-party developers. For licensed PC games, Changyou remits a pre-agreed percentage of the proceeds to the third-party developers pursuant to revenue-sharing agreements, and keeps the balance. Such revenue-sharing amounts paid to third-party developers are recorded in Changyou’s cost of revenues. Mobile Games Self-operated Mobile Games For self-operated mobile games, Changyou sells game points to its game players via third-party mobile APP stores. The mobile APP stores in turn pay Changyou proceeds after deducting their share of pre-agreed revenue-sharing amounts. Changyou’s self-operated mobile games are either developed in house or licensed from or jointly developed with third-party developers. For licensed and jointly-developed mobile games, Changyou remits a pre-agreed percentage of the proceeds to the third-party developers pursuant to revenue-sharing agreements, and keeps the balance. Such revenue-sharing amounts paid to mobile application stores and third-party developers are recorded in Changyou’s cost of revenues. Licensed Out Mobile Games Changyou also authorizes third parties to operate its mobile games. Licensed out games mainly include mobile games developed in house, such as Changyou’s mobile game Legacy TLBB Mobile, and mobile games jointly developed with third-party developers. Changyou receives monthly revenue-based royalty payments from the third-party licensee operators. Changyou receives additional up-front license fees from certain third-party licensee operators who are entitled to an exclusive right to operate Changyou’s games in specified geographic areas. Since Changyou is obligated to provide post-sale services (“PCS”), the initial license fees are allocated between the license and PCS based on relative standalone selling prices. The amount allocated to the license is recognized as revenue upon the commencement of the license period, given that Changyou’s intellectual property rights subject to the license are considered to be functional and the licensee has the right to use such intellectual property rights as they exist at the point when the license is granted, and the amount allocated to PCS is recognized as revenue ratably over the license period. Monthly revenue-based royalty payments are recognized when the relevant services are delivered, provided that collectability is reasonably assured. Changyou views the third-party licensee operators as Changyou’s customers and recognizes revenues on a net basis, as Changyou does not have the primary responsibility for fulfillment and acceptability of the game services. Changyou remits to the third-party developers a pre-agreed percentage of revenues and keeps the balance pursuant to revenue-sharing agreements. Such revenue-sharing amounts paid to third-party developers are included in Changyou’s cost of revenues or product development expenses. Other Revenues Sohu Other revenues attributable to Sohu consist primarily of revenues from paid subscription services, interactive broadcasting services, and content provided through the platforms of the three main telecommunications operators in China.
Sogou Other revenues attributable to Sogou are IVAS revenues, which are mainly from the operation of Web games and mobile games developed by third parties and the provision of online reading services, and revenues from other products and services, including smart hardware. Changyou Other revenues attributable to Changyou are primarily from its cinema advertising business and from IVAS. In its cinema advertising business, Changyou provides clients advertising placements in slots that are shown in theaters before the screening of movies. The rights to place advertisements in such advertising slots are granted to Changyou, which takes inventory risk under the contracts Changyou signs with different theaters. Changyou charges its advertising clients fees either on a per advertising-slot basis or a fixed amount for an agreed-upon number of slots during a specified contract period. When delivery of the advertising service is confirmed by the customers by their signing a form, revenues from cinema advertising are recognized based on a percentage of the advertising slots actually delivered or on a straight-line basis over the contract period. As Changyou is considered to be the principal in the arrangements with the theaters, the fees paid to the theaters are recognized as cost of revenues. Changyou provides IVAS primarily through software applications for PCs and mobile devices offered by RaidCall. Prior to March 2018, IVAS revenues also included revenues generated from the Dolphin Browser operated by MoboTap. Revenues from IVAS are recognized during the period the services are rendered or items are consumed under the gross method, as Changyou is the principal obligor for provision of the services. Contract Balances Timing of revenue recognition may differ from the timing of invoicing to customers. Accounts receivable represent amounts invoiced and revenue recognized prior to invoicing, when the Group has satisfied its performance obligations and has the unconditional right to payment. The allowance for doubtful accounts and authorized credits is estimated based upon the Group’s assessment of various factors, including historical experience, the age of the accounts receivable balances, current economic conditions and other factors that may affect the Group’s customers’ ability to pay. Contract assets as of December 31, 2018 were not material. The allowance for doubtful accounts and authorized credits was $16.9 million and $5.7 million, respectively, as of December 31, 2018 and December 31, 2017. Receipts in advance and deferred revenue relate to unsatisfied performance obligations at the end of the period and primarily consist of fees received from game players in the online game business and from advertisers in the search and search-related advertising business. Due to the generally short-term duration of the contracts, the majority of the performance obligations are satisfied in the following reporting period. The amount of revenue recognized that was included in the receipts in advance and deferred revenue balance at the beginning of the period was $111.7 million for the year ended December 31, 2018. There was no significant change in the contract assets and contract liability balances during 2018. Revenue recognized in 2018 from performance obligations related to prior years was not material. Practical Expedients The Group has used the following practical expedients as allowed under ASC 606: (i) The transaction price allocated to performance obligations that are unsatisfied or partially unsatisfied has not been disclosed, as substantially all of the Group’s contracts have a duration of one year or less. (ii) Payment terms and conditions vary by contract type, although terms generally include a requirement of prepayment or payment within one year or less. In instances where the timing of revenue recognition differs from the timing of invoicing, the Group has determined that its contracts generally do not include a significant financing component. (iii) The Group applied the portfolio approach in determining the commencement date of consumption and the estimated lives of virtual items for the recognition of games revenue, given that the effect of applying a portfolio approach to a group game players’ behaviors would not differ materially from considering each one of them individually. (iv) The Group generally expenses sales commissions when incurred because the amortization period would be one year or less. These costs are recorded within sales and marketing expenses.
Cost of Revenues Cost of Online Advertising Revenues Cost of online advertising revenues includes cost of revenues from brand advertising services as well as cost of revenues from search and search-related services. Cost of Brand Advertising Revenues Cost of brand advertising revenues mainly consists of content and license costs, salary and benefits expenses, and bandwidth leasing costs. For self-developed video content, production costs incurred in excess of the amount of revenue contracted for are expensed as incurred. Cost of Search and Search-related Advertising Revenues Cost of search and search-related advertising revenues mainly consists of traffic acquisition costs, bandwidth leasing costs, depreciation expenses, salary and benefits expenses, and share-based compensation expense. Traffic acquisition costs consist primarily of payments to third parties that direct search queries of the users to Internet properties of Sogou or distribute Sogou advertisers’ promotional links through such third parties’ Internet properties. The traffic acquisitions costs for such arrangements consist primarily of fees that Sogou pays to the third parties based on an agreed-upon unit price and revenue-sharing payments that Sogou makes to such third parties based on an agreed-upon percentage of revenues generated from users’ clicks. Cost of Online Game Revenues Cost of online game revenues mainly consists of revenue-sharing payments, salary and benefits expenses, bandwidth leasing costs, content and license costs, tax surcharges, depreciation and amortization expenses, and other direct costs. Cost of Other Revenues Cost of other revenues mainly consists of payments to theaters for pre-film screening advertising slots, revenue-sharing payments related to the IVAS business, content and license costs related to paid subscription services, and revenue-sharing payments related to interactive broadcasting services. Product Development Expenses Product development expenses mainly consist of salary and benefits expenses, technical service fees, content and license costs, facilities expenses, and depreciation and amortization expenses. These expenses are incurred for the enhancement and maintenance of the Sohu Group’s Internet platforms as well as for its products and services. The development costs of online games are expensed as incurred, including the development costs of online games prior to the establishment of technological feasibility and maintenance costs after the online games are available for marketing. Sales and Marketing Expenses Sales and marketing expenses mainly consist of advertising and promotional expenses, salary and benefits expenses, travelling and entertainment expenses, and facilities expenses. Advertising and promotional expenses generally represent the expenses of promotions to create or stimulate a positive image of the Sohu Group or a desire to subscribe for the Group’s products and services. Advertising and promotional expenses are expensed as incurred. General and Administrative Expenses General and administrative expenses mainly consist of salary and benefits expenses, professional fees, bad debts, travelling and entertainment expenses, depreciation and amortization expenses, and facilities expenses Share-based Compensation Expense Sohu (excluding Sohu Video), Sogou, Changyou, and Sohu Video have incentive plans for the granting of share-based awards, including share options and restricted share units, to members of the boards of directors, management and other key employees. For share-based awards for which a grant date has occurred, share-based compensation expense is recognized as costs and expenses in the consolidated statements of comprehensive income based on the fair value of the related share-based awards on their grant dates. For share-based awards for which the service inception date precedes the grant date, share-based compensation expense is recognized as costs and expenses in the consolidated statements of comprehensive income beginning on the service inception date and is re-measured on each subsequent reporting date before the grant date, based on the estimated fair value of the related share-based awards. Share-based compensation expense is charged to the shareholders’ equity or noncontrolling interest section in the consolidated balance sheets. The assumptions used in share-based compensation expense recognition represent management’s best estimates, but these estimates involve inherent uncertainties and the application of management judgment. If factors change or different assumptions are used, the Group’s share-based compensation expense could be materially different for any period. Moreover, the estimates of fair value are not intended to predict actual future events or the value that ultimately will be realized by employees who receive equity awards. Sohu (excluding Sohu Video), Sogou, and Changyou Share-based Awards Sohu (excluding Sohu Video) Share-based Awards In determining the fair values of share options granted by Sohu (excluding Sohu Video) as share-based awards, the public market price of the underlying shares at each reporting date was used, and a binomial valuation model was applied. In determining the fair value of restricted share units granted, the public market price of the underlying shares on the grant dates was applied. Upon the dissolution of Sohu.com Inc. on May 31, 2018, Sohu.com Limited assumed all then existing obligations of Sohu.com Inc. with respect to equity incentive awards that had been granted under Sohu.com Inc.’s Amended and Restated 2010 Stock Incentive Plan (the “Sohu 2010 Stock Incentive Plan”) and remained outstanding, and such awards were converted into the right to receive upon exercise or settlement Sohu.com Limited’s ordinary shares under the Sohu.com Limited 2018 Share Incentive Plan (the “Sohu 2018 Share Incentive Plan”) rather than shares of the common stock of Sohu.com Inc., subject to the other terms of such outstanding awards. Options for the purchase of Sohu.com Limited’s ordinary shares, including options converted from those contractually granted under the Sohu 2010 Stock Incentive Plan, are subject to vesting in four equal installments over a period of four years, with each installment vesting upon satisfaction of a service period requirement and certain subjective performance targets. Under ASC 718-10-25, no grant date can be established until a mutual understanding is reached between Sohu and the recipients clarifying the subjective performance requirements. In accordance with ASC 718-10-55, as the service inception date preceded the grant date, compensation expense was accrued beginning on the service inception date and will be re-measured on each subsequent reporting date before the grant date is established, based on the then-current fair value of the awards. The estimate of the awards’ fair values will be fixed in the period in which the grant date occurs, and cumulative compensation expense will be adjusted based on the fair value at the grant date. Sogou Share-based Awards In determining the fair value of share options granted by Sogou as share-based awards, a binomial valuation model was applied. The determination of the fair value is affected by the fair value of the ordinary shares as well as assumptions regarding a number of complex and subjective variables, including risk-free interest rates, exercise multiples, expected forfeiture rates, expected share price volatility rates, and expected dividends. Before the completion of Sogou’s IPO, the fair values of the ordinary shares were assessed using the income approach/discounted cash flow method or based on the mid-point of the estimated IPO price range, in each case with a discount for lack of marketability, given that the shares underlying the awards were not publicly traded at the time of grant. After the completion of Sogou’s IPO, the fair values of the ordinary shares were determined based on the trading price of Sogou’ ADSs in the public market. Certain persons who became Sogou employees when Tencent’s Soso search-related businesses were transferred to Sogou in 2013 had been granted restricted share units under Tencent’s share award arrangements prior to the transfer of the businesses to Sogou. These Tencent restricted share units will continue to vest under the original Tencent share award arrangements provided the transferred employees continue to be employed by Sogou during the requisite service period. After the transfer of the Soso search-related businesses to Sogou, Sogou applied the guidance in ASC 505-50 to measure the related compensation expense based on the then-current fair value at each reporting date, as the expense is deemed to have been incurred by Tencent as an investor on Sogou’s behalf. To determine the then-current fair value of the Tencent restricted share units granted to these employees, the public market price of the underlying shares at each reporting date was applied. Because Sogou is not required to reimburse Tencent for such share-based compensation expense, the related amount was recorded by Sogou as a capital contribution from Tencent. Changyou Share-based Awards In determining the fair value of ordinary shares and restricted share units granted by Changyou as share-based awards in 2008, the income approach /discounted cash flow method with a discount for lack of marketability was applied, given that the shares underlying the awards were not publicly traded at the time of grant. Changyou’s 2008 Share Incentive Plan expired in August 2018 and is no longer available for granting new share-based awards. In determining the fair value of restricted share units granted after Changyou’s IPO, the public market price of the underlying shares on the grant dates was applied. Options for the purchase of Changyou Class A ordinary shares contractually granted under the Changyou 2014 Share Incentive Plan are subject to vesting in four equal installments over a period of four years, with each installment vesting upon satisfaction of a service period requirement and certain subjective performance targets. Under ASC 718-10-25, no grant date can be established until a mutual understanding is reached between Changyou and the recipients clarifying the subjective performance requirements. In accordance with ASC 718-10-55, as the service inception date preceded the grant date, compensation expense was accrued beginning on the service inception date and will be re-measured on each subsequent reporting date before the grant date is established, based on the then-current fair value of the awards. The estimates of the awards’ fair values will be fixed in the period in which the grant date occurs, and cumulative compensation expense will be adjusted based on the fair values at the grant date. In determining the fair values of Changyou share options granted, the public market price of the underlying shares at each reporting date was used, and a binomial valuation model was applied. Compensation Expense Recognition For options and restricted share units granted with respect to Sohu (excluding Sohu Video) shares and Changyou shares, compensation expense is recognized on an accelerated basis upon the requisite service period and certain subjective performance targets being met. For share options granted with respect to Sogou shares, compensation expense is recognized over the estimated period during which the service period requirement and performance target will be met, which is usually within one year, or, after the performance target of Sogou’s completion of an IPO was met upon the completion of Sogou’s IPO on November 13, 2017, on an accelerated basis over the requisite service period, or, for options with only service period requirement, on an accelerated basis over the requisite service period. For Tencent restricted share units that Tencent had granted to employees who transferred to Sogou with the Soso search and search-related businesses, compensation expense is recognized by Sogou on an accelerated basis over the requisite service period, and the fair value of the share-based compensation is re-measured at each reporting date until the service has been provided. The number of share-based awards for which the service is not expected to be rendered over the requisite period is estimated, and no compensation expense is recorded for the number of awards so estimated. Sohu Video Share-based Awards On January 4, 2012, Sohu Video, the holding entity of Sohu’s video division, adopted a 2011 Share Incentive Plan (the “Video 2011 Share Incentive Plan”) which provides for the issuance of up to 25,000,000 ordinary shares of Sohu Video (representing approximately 10% of the outstanding Sohu Video shares on a fully-diluted basis) to management and key employees of the video division and to Sohu management. As of December 31, 2018, grants of options for the purchase of 16,368,200 ordinary shares of Sohu Video had been contractually made, of which options for the purchase of 4,972,800 ordinary shares were vested. For purposes of ASC 718-10-25, as of December 31, 2018, no grant date had occurred, because the broader terms and conditions of the option awards had neither been finalized nor mutually agreed upon with the recipients. Therefore the fair value of the awards was not determinable and could not be accounted for. In accordance with ASC 718-10-55, the Group’s management determined that the service inception date with respect to vested option awards for the purchase of 4,972,800 shares had preceded the grant date. Therefore, the Group recognized compensation expense for these vested Sohu Video share-based awards and re-measured, and will re-measure, the compensation expense on each subsequent reporting date based on the then-current fair values of these vested awards until the grant date is established. Taxation PRC Corporate Income Taxes Income taxes are accounted for using an asset and liability approach which requires the recognition of income taxes payable or refundable for the current year and deferred tax liabilities and assets for the future tax consequences of events that have been recognized in the Group’s financial statements or tax returns. Deferred income taxes are determined based on the differences between the accounting basis and the tax basis of assets and liabilities and are measured using the currently enacted tax rates and laws. Deferred tax assets are reduced by a valuation allowance, if based on available evidence, it is considered that it is more likely than not that some portion of or all of the deferred tax assets will not be realized. In making such determination, the Group considers factors including future reversals of existing taxable temporary differences, future profitability, and tax planning strategies. If events were to occur in the future that would allow the Group to realize more of its deferred tax assets than the presently recorded net amount, an adjustment would be made to the deferred tax assets that would increase income for the period when those events occurred. If events were to occur in the future that would require the Group to realize less of its deferred tax assets than the presently recorded net amount, an adjustment would be made to the valuation allowance against deferred tax assets that would decrease income for the period when those events occurred. Significant management judgment is required in determining income tax expense and deferred tax assets and liabilities.
The Group’s deferred tax assets are related to net operating losses and temporary differences between accounting basis and tax basis for its China-Based Subsidiaries and VIEs, which are subject to corporate income tax in the PRC under the PRC Corporate Income Tax Law (the “CIT Law”). PRC Withholding Tax on Dividends The CIT Law imposes a 10% withholding income tax on dividends distributed by foreign invested enterprises in the PRC to their immediate holding companies outside Mainland China. A lower withholding tax rate may be applied if there is a tax treaty between Mainland China and the jurisdiction of the foreign holding company. A holding company in Hong Kong, for example, will be subject to a 5% withholding tax rate under an arrangement between the PRC and the Hong Kong Special Administrative Region on the “Avoidance of Double Taxation and Prevention of Fiscal Evasion with Respect to Taxes on Income,” if such holding company is considered a non-PRC resident enterprise and holds at least 25% of the equity interests in the PRC foreign invested enterprise distributing the dividends, subject to approval of the PRC local tax authority. However, if the Hong Kong holding company is not considered to be the beneficial owner of such dividends under applicable PRC tax regulations, such dividend will remain subject to a withholding tax rate of 10%. PRC Value Added Tax On May 1, 2016, the transition from the imposition of PRC business tax to the imposition of VAT was expanded to all industries in China, and all of the Sohu Group’s revenues have been subject to VAT since that date. To record VAT payable, the Group adopted the net presentation method, which presents the difference between the output VAT (at rates of 6% or 17% for the years ended December 31, 2016 and 2017 and for the period from January 1, 2018 to April 30, 2018, and at rates of 6% or 16% after May 1, 2018) and the available input VAT amount (at the rate applicable to the supplier). U.S. Corporate Income Tax Sohu.com Inc., which was formerly the top-tier publicly-traded parent company of the Sohu Group, was dissolved and liquidated on May 31, 2018. Sohu.com Inc. was a Delaware corporation that was subject to U.S. corporate income tax on its taxable income at a rate of 21% for taxable years beginning after December 31, 2017 and of up to 35% for prior tax years. U.S. federal tax legislation signed into law on December 22, 2017, commonly referred to as the Tax Cuts and Jobs Act (the “U.S. TCJA”), significantly modified the U.S. Internal Revenue Code by, among other things, reducing the maximum statutory U.S. federal corporate income tax rate from 35% to 21% for taxable years beginning after December 31, 2017; limiting and/or eliminating many business deductions; migrating the U.S. to a partial territorial tax system with a one-time transition tax (the “Toll Charge”) on a mandatory deemed repatriation of previously deferred foreign earnings of certain foreign subsidiaries; subject to certain limitations, generally eliminating U.S. corporate income tax on dividends from foreign subsidiaries; and providing for new taxes on certain foreign earnings. Certain activities conducted in the PRC resulted in U.S. corporate income taxes being imposed on Sohu.com Inc. when its subsidiaries that were controlled foreign corporations (“CFCs”) generated income that was subject to Subpart F of the U.S. Internal Revenue Code (“Subpart F”). Generally, passive income, such as rents, royalties, interest, dividends, and gains from disposal of the company’s investments, is among the types of income subject to taxation under Subpart F. Any income taxable under Subpart F was taxable in the U.S. at a federal corporate income tax rate of 21%. Subpart F income also included certain income from intra-Group transactions between Sohu.com Inc.’s non-U.S. subsidiaries and VIEs and Changyou’s non-U.S. subsidiaries and VIEs or Sogou’s non-U.S. subsidiaries and VIEs, or where Sohu.com Inc.’s non-U.S. subsidiaries or VIEs made an “investment in U.S. property,” such as holding the stock in, or making a loan to, a U.S. corporation. Under a provision of the U.S. tax code commonly referred to as the CFC look-through rule, Sohu.com Inc. did not have to treat dividends received by its CFC subsidiaries as Subpart F income includible in Sohu.com Inc.’s taxable income in the U.S. To the extent that portions of Sohu.com Inc.’s U.S. taxable income, such as Subpart F income or global intangible low-taxed income (“GILTI”), had been determined to be from sources outside of the U.S., subject to certain limitations, Sohu.com Inc. could claim foreign tax credits to offset its U.S. income tax liabilities. Following the enactment of the U.S. TCJA, if dividends that Sohu.com Inc. received from its subsidiaries after January 1, 2018 were determined to be from sources outside of the U.S., subject to certain limitations, Sohu.com Inc. would generally not have been required to pay U.S. corporate income tax on those dividends. Liabilities for U.S. corporate income tax were accrued in the Company’s consolidated statements of comprehensive income and estimated tax payments were made when required by U.S. law.
Treatment of Toll Charge Related to the U.S. TCJA Beginning in the fourth quarter of 2017, the Sohu Group had recognized a provisional amount of income tax expense for the Toll Charge of $219 million, which represented management’s estimate of the amount of the Toll Charge that would have been payable by Sohu.com Inc. based on the deemed repatriation to the United States of its share of previously deferred earnings of certain of its non-U.S. subsidiaries, offset by a reduction of $4 million in liability for deferred U.S. income tax, as a result of the U.S. TCJA. The Sohu Group included the provisional amount of the Toll Charge of $219 million in its interim financial statements through the quarter ended September 30, 2018, in reliance on Staff Accounting Bulletin No. 118 (“SAB 118”). For the fourth quarter of 2018, the Sohu Group’s management re-evaluated the impact on the Sohu Group of the Toll Charge under the U.S. TCJA. Management determined that it was more likely than not, based on the technical merits, that the tax position that the Sohu Group had no Toll Charge liability would be sustained. The Group recognized a tax benefit in the amount of $77 million, which was the largest amount that management determined to be greater than 50% likely to be realized upon settlement with the U.S. IRS. As a result, as of December 31, 2018 the Sohu Group had an unrecognized tax benefit in the amount of $142 million, which represented the difference between the tax benefit recognized in the fourth quarter of 2018 and management’s previous estimate of the Toll Charge. In addition, the Sohu Group accrued $2 million in interest on the unrecognized tax benefit. The tax benefit recognized and the unrecognized tax benefit in relation to the Toll Charge may be subject to further adjustment in subsequent periods based on facts and circumstances that arose after December 31, 2018, such as final IRS Toll Charge regulations published in February 2019, and any future circumstances such as any guidance issued by the U.S. Department of the Treasury, any U.S. IRS challenge of the Group’s position on the Toll Charge, and management’s further judgment and estimates. Uncertain Tax Positions The Sohu Group is subject to various taxes in different jurisdictions, primarily the U.S. and the PRC. Management reviews regularly the adequacy of the provisions for taxes as they relate to the Group’s income and transactions. In order to assess uncertain tax positions, the Group applies a more likely than not threshold and a two-step approach for tax position measurement and financial statement recognition. For the two-step approach, the first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount that is more than 50% likely to be realized upon settlement. Net Income /(Loss) per Share Basic net income /(loss) per share is computed using the weighted average number of ordinary shares outstanding during the period. Diluted net income /(loss) per share is computed using the weighted average number of ordinary shares and, if dilutive, potential ordinary shares outstanding during the period. Potential ordinary shares comprise shares issuable upon the exercise or settlement of share-based awards using the treasury stock method. The dilutive effect of share-based awards with performance requirements is not considered before the performance targets are actually met. The computation of diluted net income /(loss) per share does not assume conversion, exercise, or contingent issuance of securities that would have an anti-dilutive effect (i.e. an increase in earnings per share amounts or a decrease in loss per share amounts) on net income /(loss) per share. Additionally, for purposes of calculating the numerator of diluted net income /(loss) per share, the net income /(loss) attributable to the Sohu Group is calculated as follows: Sogou’s net income /(loss) attributable to Sohu Before Sogou’s IPO Before Sogou’s IPO, Sogou’s net income /(loss) attributable to Sohu was determined using the percentage that the weighted average number of Sogou shares held by Sohu represented of the weighted average number of the Sogou Pre-IPO Preferred Shares and Pre-IPO Ordinary Shares, shares issuable upon the conversion of convertible preferred shares under the if-converted method, and shares issuable upon the exercise or settlement of share-based awards under the treasury stock method, and was not determined by allocating Sogou’s net income /(loss) to Sohu using the methodology for the calculation of net income /(loss) attributable to the Sogou noncontrolling shareholders. After Sogou’s IPO After Sogou’s IPO, Sogou’s net income /(loss) attributable to Sohu is determined using the percentage that the weighted average number of Sogou shares held by Sohu represents of the weighted average number of Sogou ordinary shares and shares issuable upon the exercise or settlement of share-based awards under the treasury stock method, and not by using the percentage held by Sohu of the total economic interest in Sogou, which is used for the calculation of basic net income per share. In the calculation of Sohu’s diluted net income /(loss) per share, assuming a dilutive effect, the percentage of Sohu’s shareholding in Sogou was calculated by treating convertible preferred shares issued by Sogou as having been converted at the beginning of the period and unvested Sogou share options with the performance targets achieved as well as vested but unexercised Sogou share options as having been exercised during the period. The dilutive effect of share-based awards with a performance requirement was not considered before the performance targets were actually met. Assuming an anti-dilutive effect, all of these Sogou shares and share options are excluded from the calculation of Sohu’s diluted income /(loss) per share. As a result, Sogou’s net income /(loss) attributable to Sohu on a diluted basis equals the number used for the calculation of Sohu’s basic net income /(loss) per share. Changyou’s net income /(loss) attributable to Sohu Changyou’s net income /(loss) attributable to Sohu is determined using the percentage that the weighted average number of Changyou shares held by Sohu represents of the weighted average number of Changyou ordinary shares and shares issuable upon the exercise or settlement of share-based awards under the treasury stock method, and not by using the percentage held by Sohu of the total economic interest in Changyou, which is used for the calculation of basic net income per share. In the calculation of Sohu’s diluted net income /(loss) per share, assuming a dilutive effect, all of Changyou’s existing unvested restricted share units and share options, and vested restricted share units and share options that have not yet been settled, are treated as vested and settled by Changyou under the treasury stock method, causing the percentage of the weighted average number of shares held by Sohu in Changyou to decrease. As a result, Changyou’s net income /(loss) attributable to Sohu on a diluted basis decreased accordingly. Assuming an anti-dilutive effect, all of these Changyou restricted share units and share options are excluded from the calculation of Sohu’s diluted net income /(loss) per share. As a result, Changyou’s net income /(loss) attributable to Sohu on a diluted basis equals the number used for the calculation of Sohu’s basic net income /(loss) per share. Fair Value of Financial Instruments U.S. GAAP establishes a three-tier hierarchy to prioritize the inputs used in the valuation methodologies in measuring the fair value of financial instruments. This hierarchy also requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The three-tier fair value hierarchy is: Level 1 - observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets. Level 2 - include other inputs that are directly or indirectly observable in the market place. Level 3 - unobservable inputs which are supported by little or no market activity. The Sohu Group’s financial instruments consist primarily of cash equivalents, short-term investments, accounts receivable, financing receivables, prepaid and other current assets, long-term investments, restricted time deposits, accounts payable, accrued liabilities, receipts in advance and deferred revenue, short-term bank loans, other short-term liabilities, long-term bank loans and long-term accounts payable. Cash Equivalents The Sohu Group’s cash equivalents mainly consist of time deposits with original maturities of three months or less, and highly liquid investments that are readily convertible to known amounts of cash. Short-term Investments For investments in financial instruments with a variable interest rate indexed to the performance of underlying assets, the Sohu Group elected the fair value method at the date of initial recognition and carried these investments subsequently at fair value. Changes in fair values are reflected in the consolidated statements of comprehensive income. Accounts Receivable, Net The carrying value of accounts receivable is reduced by an allowance that reflects the Sohu Group’s best estimate of the amounts that will not be collected. The Group makes estimations of the collectability of accounts receivable. Many factors are considered in estimating the general allowance, including reviewing delinquent accounts receivable, performing an aging analysis and a customer credit analysis, and analyzing historical bad debt records and current economic trends.
Financing Receivables, Net Financing receivables consist primarily of small consumer loans to individual borrowers. Such amounts are recorded at the principal amount and interest accrued, net of allowance for credit losses that reflects Sogou’s best estimate of the amounts that will not be collected. Interest on loans is accrued based on the contractual interest rates of the loans when earned. The loan periods granted by Sogou to the borrowers related to the small consumer loans are generally within one year. The allowance for credit losses is determined at a level believed to be reasonable to absorb probable losses inherent in the loan portfolio as of each balance sheet date. The allowance is provided based on an assessment performed on a portfolio basis and is estimated on a quarterly basis or more often as necessary based on the delinquency rate, the aging of the amount due and other relevant factors. Foreign Exchange Forward Contracts Foreign exchange forward contracts are initially recognized on the date a foreign exchange forward contract is entered into and are subsequently measured at fair value. Restricted Time Deposits Restricted time deposits are valued based on the prevailing interest rates in the market using the discounted cash flow method. Equity Investments Investments in entities are recorded as equity investments under long-term investments. For entities over which the Group can exercise significant influence but does not own a majority equity interest or control, the equity method is applied, and the Group adjusts the carrying amount of an investment and recognizes investment income or loss for the Group’s share of the earnings or loss of the investee after the date of investment. For those equity investments accounted for other than under the equity method or those that result in consolidation, the fair value method is applied. However, for equity investments that do not have readily determinable fair values, the Group chooses to account for them at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer. If this measurement alternative is elected, changes in the carrying value of the equity investments will be required to be made whenever there are observable price changes in transactions for identical or similar investments of the same issuer. The implementation guidance notes that an entity should make a “reasonable effort” to identify price changes that are known or that can reasonably be known. Long-Lived Assets Long-lived assets include fixed assets and intangible assets. Fixed Assets Fixed assets mainly comprise office buildings, leasehold improvements, building improvements, vehicles, office furniture and computer equipment, and hardware. Fixed assets are recorded at cost less accumulated depreciation with no residual value. Depreciation is computed using the straight-line method over the estimated useful lives of the assets.
Expenditure for maintenance and repairs is expensed as incurred. The gain or loss on the disposal of fixed assets is the difference between the net sale proceeds and the carrying amounts of the relevant assets and is recognized in operating expenses in the consolidated statements of comprehensive income.
Intangible Assets Intangible assets mainly comprise purchased video content, operating rights for licensed games, domain names and trademarks, computer software, and developed technologies. Intangible assets are recorded at cost less accumulated amortization with no residual value. Amortization of intangible assets other than purchased video content is computed using the straight-line method over their estimated useful lives. Amortization of purchased video content is computed based on the trend in viewership accumulation over the shorter of the applicable license period or two years. The estimated useful lives of the Group’s intangible assets are listed below:
Sohu Video enters into nonmonetary transactions to exchange online broadcasting rights for purchased video content with other online video broadcasting companies. Under ASC 845, the cost of a nonmonetary asset acquired in exchange for another nonmonetary asset is the fair value of the asset surrendered to obtain the acquired nonmonetary asset, and a gain or loss should be recognized on the exchange. The fair value of the asset received should be used to measure the cost if the fair value of the asset received is more reliable than the fair value of the asset surrendered. The Sohu Group records these nonmonetary exchanges at the fair values of the online broadcasting rights for purchased video content and recognize any net gain or loss from such exchange transactions. Impairment of Long-lived Assets other than Purchased Video Content In accordance with ASC 360-10-35, the Sohu Group reviews the carrying values of long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying value of an asset may not be recoverable. The evaluation is performed at the lowest level of identifiable cash flows independent of other assets. Recoverability of these assets is measured by a comparison of the carrying amounts to the future undiscounted cash flows the assets are expected to generate. If such review indicates that the carrying amount of the long-lived assets is not recoverable, the carrying amount of such assets is reduced to fair value. The estimation of future cash flows requires significant management judgment based on the Group’s historical results and anticipated results and is subject to many factors. The discount rate that is commensurate with the risk inherent in the Group’s business model is determined by its management. Impairment of Purchased Video Content Purchased video content is stated at the lower of cost less accumulated amortization, or net realizable value (“NRV”). In accordance with ASC 920-350-35, if management’s expectations of the programming usefulness of a program, series, package, or program segment are revised downward, it may be necessary to write down unamortized cost to estimated NRV. A write-down from unamortized cost to a lower estimated NRV establishes a new cost basis. Accordingly, the Group measures the video content’s impairment loss by comparing the content’s carrying value to its NRV. An impairment loss will be recorded if the carrying value of video content is higher than its NRV. The impairment to be recognized is measured by the amount by which the carrying value of video content exceeds its NRV. Goodwill Goodwill represents the excess of the purchase price over the fair value of the identifiable assets and liabilities acquired as a result of the Sohu Group’s acquisitions of interests in its subsidiaries and consolidated VIEs. If the initial accounting for a business combination is incomplete by the end of the reporting period in which the combination occurs, the Group reports in its financial statements provisional amounts for the items for which the accounting is incomplete. If a measurement period adjustment is identified, the Group recognizes the adjustment as part of the acquisition accounting. The Sohu Group increases or decreases the provisional amounts of identifiable assets or liabilities by means of increases or decreases in goodwill for measurement period adjustments. In accordance with ASC 350, the Group does not amortize goodwill, but tests it for impairment. The Group tests goodwill for impairment at the reporting unit level on an annual basis as of October 1, and between annual tests when an event occurs or circumstances change that could indicate that the asset might be impaired. Under ASC 350-20-35, the Group has the option to choose whether it will apply a qualitative assessment first and then a quantitative assessment, if necessary, or to apply a quantitative assessment directly. For reporting units applying a qualitative assessment first, the Group starts the goodwill impairment test by assessing qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If it is more likely than not that the fair value of a reporting unit is less than its carrying amount, the quantitative impairment test is mandatory. Otherwise, no further testing is required. The quantitative impairment test consists of a comparison of the fair value of the reporting unit with its carrying value. For reporting units directly applying the quantitative assessment, the Group performs the two-step goodwill impairment test by first quantitatively comparing the fair values of those reporting units to their carrying amounts, including goodwill. After performing the assessment, if the carrying amounts of the reporting units are higher than their fair value, the Group performs the second step of the quantitative goodwill impairment test by comparing the implied fair value of the reporting unit’s goodwill with the carrying amount of that goodwill, and if the carrying amount of the reporting unit’s goodwill exceeds the implied fair value of that goodwill, an impairment loss is recognized in an amount equal to that excess. Application of a goodwill impairment test requires significant management judgment, including the identification of reporting units, assigning assets and liabilities to reporting units, assigning goodwill to reporting units, and determining the fair value of each reporting unit. The Group estimates fair value using the income approach and the market approach. The judgment in estimating the fair value of reporting units includes estimating future cash flows, determining appropriate discount rates, control premium, comparable companies’ multipliers, and making other assumptions. Changes in these estimates and assumptions could materially affect the determination of fair value for each reporting unit. Comprehensive Income Comprehensive income is defined as the change in equity of a company during a period from transactions and other events and circumstances excluding transactions resulting from investments from owners and distributions to owners. Accumulated other comprehensive income, as presented on the Sohu Group’s consolidated balance sheets, includes a cumulative foreign currency translation adjustment, and change in unrealized gains /(losses) on equity securities classified as available-for-sale before the adoption of ASU 2016-01. Functional Currency and Foreign Currency Translation An entity’s functional currency is the currency of the primary economic environment in which it operates, normally that is the currency of the environment in which the entity primarily generates and expends cash. Management’s judgment is essential to determine the functional currency by assessing various indicators, such as cash flows, sales price and market, expenses, financing and intra-Group transactions and arrangements. The functional currency of Sohu.com Limited, and its predecessor Sohu.com Inc., is the U.S. dollar. The functional currency of the Sohu Group’s subsidiaries in the U.S., the Cayman Islands, the British Virgin Islands and Hong Kong is the U.S. dollar. The functional currencies of the Sohu Group’s subsidiaries and VIEs in other countries are the national currencies of those counties, rather than the U.S. dollar. Foreign currency transactions denominated in currencies other than the functional currency are translated into the functional currency using the exchange rates prevailing at the dates of the transactions. Monetary assets and liabilities denominated in foreign currencies at the balance sheet date are re-measured at the applicable rates of exchange in effect at that date. Gains and losses resulting from foreign currency re-measurement are included in the consolidated statements of comprehensive income. Financial statements of entities with a functional currency other than the U.S. dollar are translated into U.S. dollars, which is the reporting currency. Assets and liabilities are translated at the current exchange rate in effect at the balance sheet date, and revenues and expenses are translated at the average of the exchange rates in effect during the reporting period. Shareholders’ equity accounts are translated using the historical exchange rates at the date the entry to shareholders’ equity was recorded, except for the change in retained earnings during the year, which is translated using the historical exchange rates used to translate each period’s income statement. Differences resulting from translating a foreign currency to the reporting currency are recorded in accumulated other comprehensive income in the consolidated balance sheets. Impact of Recently Issued Accounting Pronouncements Revenue from Contracts with Customers. In May 2014, the FASB issued Accounting Standards Update (“ASU”) No. 2014-09, ‘‘Revenue from Contracts with Customers (Topic 606).’’ This guidance supersedes current guidance on revenue recognition in Topic 605, ‘‘Revenue Recognition.’’ In addition, there are disclosure requirements related to the nature, amount, timing, and uncertainty of revenue recognition. On January 1, 2018, the Sohu Group adopted ASC 606, applying the modified retrospective method to contracts that were not completed as of January 1, 2018. The adoption did not have a material impact on retained earnings as of January 1, 2018. Results for reporting periods beginning on or after January 1, 2018 are presented under ASC 606, while prior period amounts are not adjusted and continue to be reported in accordance with the Group’s historic accounting under ASC 605. Additional disclosures have been made. Please see the Notes to Consolidated Financial Statements for details. Financial Instruments (Subtopic 825-10). In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments- Recognition and Measurement of Financial Assets and Financial Liabilities. This new guidance amends certain aspects of recognition, measurement, presentation and disclosure of financial instruments. The main provisions require equity investments (except those accounted for under the equity method of accounting or those that result in consolidation of the investee) to be measured at fair value through earnings, unless they qualify for a measurement alternative. The new guidance will require a modified retrospective application to all outstanding instruments beginning January 1, 2018, with a cumulative effect adjustment recorded to opening retained earnings as of the beginning of the first period in which the guidance becomes effective. However, changes to the accounting for equity securities without a readily determinable fair value will be applied prospectively. Additional disclosures have been made. Please see the Notes to Consolidated Financial Statements for details. Statements of Cash Flows (Topic 230): Restricted Cash. In November 2016, the FASB issued ASU No. 2016-18, Statements of Cash Flows (Topic 230): Restricted Cash. This guidance requires that a statement of cash flows explain the changes during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statements of cash flows. The standard is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. The standard should be applied to each period presented using a retrospective transition method. The adoption of this standard resulted in restricted cash and restricted time deposits being included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statements of cash flows. Please See Note 10. Other accounting standards adopted beginning January 1, 2018 do not have a significant impact on the Sohu Group’s consolidated financial statements. Impact of Recently Issued Accounting Pronouncements not Yet Adopted Leases. On February 25, 2016, the FASB issued ASU No. 2016-02, Leases, which requires an entity to recognize both assets and liabilities arising from finance and operating leases, along with additional qualitative and quantitative disclosures. ASU No. 2016-02 requires a lessee to recognize a liability in its balance sheet to make lease payments (a “lease liability”) and a right-of-use asset representing its right to use the underlying asset for the lease term. In transition, lessees and lessors are required to recognize and measure leases at the beginning of the earliest comparative period presented, or at the beginning of the period of adoption. ASU 2016-02 is required to be adopted at the beginning of the first quarter of fiscal year 2019. The Sohu Group expects to record a right-of-use asset of approximately $26.7 million and a lease liability of approximately $24.2 million on ASU 2016-02’s adoption date of January 1, 2019, primarily related to the Sohu Group’s leased office space. The Sohu Group will use a modified retrospective approach and will not restate prior periods. The Sohu Group expects to implement new accounting policies as well as to elect certain practical expedients available to it under ASU 2016-02, including those related to capitalization thresholds and leases with terms of less than 12 months. The Sohu Group’s implementation of the amended lease guidance is subject to the same internal controls over financial reporting that it applies to its consolidated financial statements. Financial Instruments-Credit Losses. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments-Credit Losses (Topic 326), which requires entities to measure all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. This replaces the existing incurred loss model and is applicable to the measurement of credit losses on financial assets measured at amortized cost. This guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Early application will be permitted for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. The Sohu Group does not expect to adopt ASU 2016-13 early and is currently evaluating the impact that the standard will have on its consolidated financial statements and related disclosures. Simplifying the Test for Goodwill Impairment. In January 2017, the FASB issued ASU No. 2017-04, “Simplifying the Test for Goodwill Impairment.” The guidance removes Step 2 of the goodwill impairment test, which requires a hypothetical purchase price allocation. A goodwill impairment will now be the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. The guidance should be adopted on a prospective basis for the annual or any interim goodwill impairment tests beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The Sohu Group does not expect to adopt ASU 2017-04 early and is currently evaluating the impact of adopting this standard on its consolidated financial statements.

The following table summarizes the Sohu Group’s other income /(expense) (in thousands):
Note (1): The increase for 2018 compared to 2017 mainly consisted of $33.4 million in income earned from investments in financial instruments. Note (2): The increase for 2018 compared to 2017 mainly consisted of $17.8 million in investment income recognized in the third quarter of 2018 by Sogou due to the observable change in the price of Zhihu Technology Limited (“Zhihu”) after the adoption of ASU 2016-01, offset by a $3.6 million investment loss representing a change in the fair value of Hylink Digital Solution Co., Ltd (“Hylink”). Note (3): In the second quarter of 2016, the Sohu Group recognized a one-time expense of $27.8 million that was related to a donation by Sogou to Tsinghua University related to setting up a joint research institute focusing on artificial intelligence technology. Note (4): Before the adoption of ASU 2016-01, the Group recognized an other than temporary impairment loss of $5.8 million in the third quarter of 2017 that was related to Keyeast Co., Ltd. (“Keyeast”), an investment measured as available-for-sale equity securities. The Sohu Group reported the investment at fair value using a market approach based on Keyeast’s stock price on the South Korean stock market. The fair value was continually below its original cost for a twelve-month period ended July 31, 2017. Management considered the decline in the fair value to be other-than-temporary. |

In February 2016, Sohu invested an additional $10.5 million in Fox Financial, see Note 10 - Fair Value Measurements - Financial Instruments Measured at Fair Value - Equity Investments. Changyou’s Loan Arrangements with Fox Financial Commencing in April 2015, certain subsidiaries of Changyou and certain subsidiaries of Fox Financial entered into a series of loan agreements pursuant to which the subsidiaries of Changyou are entitled to draw down HK dollar-denominated or U.S. dollar-denominated loans from the Fox Financial subsidiaries and the Fox Financial subsidiaries are entitled to draw down equivalent RMB-denominated loans from the subsidiaries of Changyou, to facilitate each other’s business operations. All of the loans carry a fixed rate of interest which approximates the current market interest rate. As of December 31, 2017, Changyou had U.S. dollar-denominated loans payable to Fox Financial in a total amount of approximately $29.8 million, and RMB-denominated loans receivable from Fox Financial in a total amount of approximately $29.8 million. For the year of 2017, Changyou incurred interest expense of $0.7 million and earned interest income of $1.2 million.

| Fair Value Measurements |
Fair Value of Financial Instruments The Sohu Group’s financial instruments consist primarily of cash equivalents, short-term investments, accounts receivable, prepaid and other current assets, long-term investments, restricted time deposits, accounts payable, accrued liabilities, receipts in advance and deferred revenue, short-term bank loans, other short-term liabilities, long-term accounts payable and long-term bank loans. U.S. GAAP establishes a three-tier hierarchy to prioritize the inputs used in the valuation methodologies in measuring the fair value of financial instruments. This hierarchy also requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The three-tier fair value hierarchy is: Level 1 - observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets. Level 2 - include other inputs that are directly or indirectly observable in the market place. Level 3 - unobservable inputs which are supported by little or no market activity. Financial Instruments Measured at Fair Value The following table sets forth the financial instruments, measured at fair value, by level within the fair value hierarchy as of December 31, 2017 (in thousands):
The following table sets forth the financial instruments, measured at fair value by level within the fair value hierarchy, as of December 31, 2018 (in thousands):
Cash Equivalents The Sohu Group’s cash equivalents mainly consist of time deposits with original maturities of three months or less, notice deposits, and highly liquid investments that are readily convertible to known amounts of cash. The fair values of cash equivalents are determined based on the pervasive interest rates in the market. The Group classifies the valuation techniques that use the pervasive interest rates input as Level 2 of fair value measurements. Generally, there are no quoted prices in active markets for identical cash equivalents at the reporting date. In order to determine the fair value, the Group must use the discounted cash flow method and observable inputs other than quoted prices in active markets for identical assets and liabilities, quoted prices for identical or similar assets or liabilities in inactive markets, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Short-term Investments In accordance with ASC 825, for investments in financial instruments with a variable interest rate indexed to performance of underlying assets, the Sohu Group elected the fair value method at the date of initial recognition and carried these investments at fair value. Changes in the fair value are reflected in the consolidated statements of comprehensive income as other income /(expense). To estimate fair value, the Group refers to the quoted rate of return provided by banks at the end of each period using the discounted cash flow method. The Group classifies the valuation techniques that use these inputs as Level 2 of fair value measurements. As of December 31, 2018 and December 31, 2017, the Sohu Group’s investment in these financial instruments was $1.0 billion and $818.9 million, respectively. The investment instruments were issued by commercial banks in China, and have a variable interest rate indexed to performance of underlying assets. Since these investments’ maturity dates are within one year, they are classified as short-term investments. For the year ended December 31, 2018 and 2017, the Sohu Group recorded a gain from changes in the fair value of short-term investments in the amounts of $40.3 million and $13.9 million in the consolidated statements of comprehensive income, respectively. Foreign Exchange Forward Contracts In September 2016 and January 2017, Changyou entered into foreign exchange forward contracts with banks in aggregate notional amounts of $100 million and $50 million, respectively. Changyou entered into such foreign exchange forward contracts in compliance with its risk management policy for the purpose of eliminating the negative impact on earnings and equity resulting from fluctuations in the exchange rate between the U.S. dollar and the RMB. The instruments are marked-to-market at each period-end with the associated changes in fair value recognized in the line item “Other income /(expense), net” in the consolidated statements of comprehensive income and “Other short-term liabilities” or “Prepaid and other current assets” in the consolidated balance sheets. The net cash inflow and outflow related to the settlement of the forward contracts are recorded in the line item “Other investing activities” under “Cash flows from investing activities” in the consolidated statements of cash flows. In January 2018, Changyou settled the remaining foreign exchange forward contracts with a realized loss of $0.2 million recognized in the consolidated statements of comprehensive income for the year ended December 31, 2018. For the year ended December 31, 2017, the Sohu Group recorded an unrealized loss of $7.2 million, resulting from changes in the fair values of forward contracts in the consolidated statements of comprehensive income. For the years ended December 31, 2018 and 2017, the Sohu Group recorded cash outflows related to the forward contracts of $0.9 million and $3.5 million, respectively, in the consolidated statements of cash flows. As of December 31, 2018, the carrying value of the foreign exchange forward contracts recognized in other short-term liabilities was nil. The Group estimated the fair values of foreign exchange forward contracts using the Black-Scholes model. The fair values of the forward contracts were estimated based on quoted forward exchange prices at the reporting date. The Group classifies the fair value measurement of the forward contracts based on such inputs as Level 2 of fair value measurements. Restricted Time Deposits Restricted time deposits are valued based on the prevailing interest rates in the market using the discounted cash flow method. The Sohu Group classifies the valuation techniques that use these inputs as Level 2 of fair value measurements. Changyou Loans from Offshore Banks, Secured by Time Deposits In 2018, Changyou drew down loans from the Hong Kong branches of PRC banks, which were secured by an equivalent or greater amount of RMB deposits by Changyou in the PRC branches of the banks. The loans from the Hong Kong branches of the lending banks were classified as short-term or long-term bank loans based on the loans’ payment terms. For the year ended December 31, 2018, interest income from the restricted time deposits securing the loans was $1.7 million, and expense for interest on the loans was $1.4 million.
Equity Investments ASU 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities, amends certain aspects of recognition, measurement, presentation and disclosure of financial instruments. The main provisions require equity investments (except those accounted for under the equity method of accounting or those that result in consolidation of the investee) to be measured at fair value through earnings, unless they qualify for a measurement alternative. The new guidance will require modified retrospective application to all outstanding instruments beginning January 1, 2018, with a cumulative effect adjustment recorded to opening accumulated deficit as of the beginning of the first period in which the guidance becomes effective. However, changes to the accounting for equity securities without a readily determinable fair value will be applied prospectively. The following table illustrates the effect of the adoption of ASU 2016-01 by presenting a comparison of selected line items from the Group’s consolidated statement of comprehensive income for the year ended December 31, 2018, as actually reported and as they would have been reported under standards previously in effect (in thousands, except per share data):
The following table illustrates the effect of the adoption of ASU 2016-01 by presenting a comparison of selected line items from the Group’s consolidated balance sheet as of December 31, 2018, as actually reported and as they would have been reported under standards previously in effect (in thousands, except per share data):
The adoption of ASU 2016-01 did not change the Group’s consolidated statement of cash flows for the year ended December 31, 2018.
Equity Investments Accounted for Using the Equity Method Investment in Fox Financial Under an agreement between Sohu and Fox Financial entered into in August 2014, Sohu invested $4.8 million and $16.1 million in Fox Financial on August 2014 and April 2015, respectively. In February 2016, Sohu invested an additional $10.5 million in Fox Financial. Sohu accounted for its investments in Fox Financial under long-term investments. These investments include both preferred shares and ordinary shares. Sohu elected to account for its investment in Fox Financial’s preferred shares at cost less impairments, adjusted by observable price changes, since they were not considered to be ordinary shares in substance and had no readily determinable fair value. There was not any observable price change in Sohu’s investment in Fox Financial in the year ended December 31, 2018. Sohu accounted for its investment in Fox Financial’s ordinary shares under the equity method, since Sohu can exercise significant influence through its board seat in Fox Financial, but does not own a majority of Fox Financial’s equity capital or control Fox Financial. In March 2017, Fox Financial issued additional ordinary shares to new investors, while shares held by Sohu remained unchanged. As a result, Sohu’s percentage of ordinary shares held was diluted from 7% to 6%. The Group recognized dilution gain of $0.7 million in other income for the three months ended March 31, 2017. As of December 31, 2018, the carrying value of Sohu’s investment in Fox Financial was $23.8 million. Equity Investments with Readily Determinable Fair Values Effective as of January 1, 2018, all equity investments in unconsolidated entities (other than those accounted for using the equity method of accounting) will generally be measured at fair value through earnings. There will no longer be an available-for-sale classification (changes in fair value previously reported in other comprehensive income) for equity securities with readily determinable fair values. Equity investments with readily determinable fair values are valued using the market approach based on the quoted prices in active markets at the reporting date. The Group classifies the valuation techniques that use these inputs as Level 1 of fair value measurements. Investment in Keyeast On August 12, 2014, Sohu acquired approximately 6% of the total outstanding common shares of Keyeast, a Korean-listed company, for a purchase price of $15.1 million. The Sohu Group classified this investment as equity investments with readily determinable fair values under long-term investments, and reported it at fair value using a market approach based on Keyeast’s stock price on the South Korean stock market. The fair value of this investment was continually below its original cost for a twelve-month period ended July 31, 2017. Management considered the decline in the fair value to be other-than-temporary, and the Sohu Group recognized an impairment loss of $5.8 million in other income /(expense) in the Sohu Group’s consolidated statements in the third quarter of 2017. Starting from January 1, 2018, Sohu applied ASU 2016-01 by means of a reclassification of $0.9 million from other comprehensive income to accumulated deficit in relation to the fair value change of investment in Keyeast previously reported in other comprehensive income. In the first quarter of 2018, Sohu disposed of all of its shares in Keyeast for $11.2 million, and recognized a disposal gain of $1.0 million in other income /(expense) in the Sohu Group’s consolidated financial statements. Investment in Hylink Digital Solution Co., Ltd (“Hylink”) On May 5, 2011, Sohu acquired 2% of the equity interests of Hylink for a purchase price of $2.3 million (RMB15 million). Given that Sohu neither controls nor has significant influence over Hylink, and the equity interest of Hylink did not have a readily determinable fair value, Sohu previously accounted for this investment using the cost method. On August 2, 2017, Hylink completed its IPO on the Shanghai Stock Exchange. Upon the completion of Hylink’s IPO, Sohu’s interest in Hylink was diluted to 1.5% of Hylink’s total ordinary shares then outstanding. The Sohu Group reclassified this investment as an equity investment with a readily determinable fair value and measured its fair value based on Hylink’s stock price on the Shanghai Stock Exchange. Beginning January 1, 2018, Sohu applied ASU2016-01 by means of a reclassification of $6.6 million (RMB43.2 million) from other comprehensive income to accumulated deficit in relation to the change in the fair value of the investment in Hylink previously reported in other comprehensive income. As of December 31, 2018, the fair value of the Hylink equity securities held by Sohu was $6.8 million (RMB46.6 million) and Sohu recognized an unrealized loss representing a change in fair value of $3.9 million (RMB26.0 million) for the year ended December 31, 2018 in other income /(expense) in the Sohu Group’s consolidated financial statements. Equity Investments without Readily Determinable Fair Values Based on ASU 2016-01, an entity will be able to elect to record equity investments without readily determinable fair values and not accounted for by the equity method at cost, less impairment, adjusted for subsequent observable price changes. Entities that elect this measurement alternative will report changes in the carrying value of the equity investments in current earnings.
If this measurement alternative is elected, changes in the carrying value of the equity investment will be required to be made whenever there are observable price changes in transactions for identical or similar investments of the same issuer. The implementation guidance notes that an entity should make a “reasonable effort” to identify price changes that are known or that can reasonably be known. When observable price changes were identified, the Group used the back-solve method to re-measure the fair value of the investments and to determine the amount that should be recorded as upward or downward adjustments. The back-solve method requires considering the rights and preferences of each classes of equity and solving for the total equity value that is consistent with a recent transaction of the subject company’s securities. This method requires making assumptions on future outcomes available to the subject company, the probability of each scenario, expected time to liquidity events, volatility and risk-free rate. The Group classifies these non-recurring fair value measurement as Level 3 of fair value measurement. Long-term Investment in Zhihu As of December 31, 2018, Sogou had invested a cumulative total of $18.9 million in Zhihu, which is a company that engages primarily in the business of operating an online question and answer-based knowledge and information-sharing platform. Sogou elected to account for the investment in Zhihu at cost less impairments, adjusted by observable price changes, since Sogou does not have significant influence over Zhihu and its investment in Zhihu is without readily determinable fair value. In the third quarter of 2018, Sogou recognized $17.8 million in investment income with respect to the observable change in the price of Zhihu. Long-term Investment in Hainan Yun Jiang Technology Co., Ltd. (“Hainan Yun Jiang”) In March 2018, Sogou invested $12.7 million (or RMB80 million) in Hainan Yun Jiang, a high-tech enterprise that engages primarily in the business of operating on-line and off-line education with artificial intelligence as its core. Sogou elected to account for the investment in Hainan Yun Jiang at cost less impairments, adjusted by observable price changes, since Sogou does not have significant influence over Hainan Yun Jiang and its investment in Hainan Yun Jiang is without readily determinable fair value. There was no observable price change for the year ended December 31, 2018. Short-term Receivables and Payables Accounts receivable and prepaid and other current assets are financial assets with carrying values that approximate fair value due to their short-term nature. Short-term accounts payable, accrued liabilities, receipts in advance and deferred revenue, short-term bank loans and other short-term liabilities are financial liabilities with carrying values that approximate fair value due to their short-term nature. For short-term receivables and payables, the Group estimated fair values using the discounted cash flow method. The Group classifies the valuation technique as Level 2 of fair value measurements. Short-term Bank Loans For short-term bank loans, the rates of interest under the agreements with the lending banks were determined based on the prevailing interest rates in the market. The Sohu Group estimated fair values using the discounted cash flow method and classifies the valuation techniques that use these inputs as Level 2 of fair value measurements.
In May 2017, Sohu entered into a factoring contract with recourse with HSBC, pursuant to which Sohu may borrow from HSBC from time to time up to a combined aggregate of RMB180.0 million (or $26.2 million), which is the upper limit reviewed by HSBC at least annually. The loan is secured by up to RMB198.0 million (or $28.8 million) of Sohu’s accounts receivable and guaranteed by Sohu Media. Interest accrues on the principal amounts of the loans outstanding at an annual rate agreed to by HSBC and Sohu upon drawdown. As of both December 31, 2018 and December 31, 2017, the total outstanding balance of the loan was nil.
In May 2017, Sohu entered into credit agreements with Ping An Bank pursuant to which Sohu was entitled to borrow from Ping An Bank from time to time until May 18, 2020 up to a combined aggregate of RMB2.50 billion (or $364.3 million). The loan was initially secured by pledges of Sohu’s two buildings and guaranteed by Sohu.com (Game) Limited (“Sohu Game”). The initial interest rate for the loans was an annual rate equal to 115% of the rate published by the PBOC. In July 2017, Sohu entered into an amendment of its loan arrangements with Ping An Bank pursuant to which interest on outstanding principal amounts accrued at a rate designated separately upon each drawdown based on the benchmark loan rate published by the PBOC with reference to then prevailing market interest rates. In July 2017, Sohu drew down from Ping An Bank pursuant to the loan arrangements a loan with a term of 12 months in the amount of RMB400.0 million (or approximately $58.3 million) and an interest rate of 6.525% per annum, which was 150% of the rate published by the PBOC as of the date of the drawdown. In September 2017, Sohu entered into another amendment of its loan arrangements with Ping An Bank pursuant to which the maximum amount that Sohu was entitled to borrow was reduced from RMB2.50 billion (or $364.3 million) to RMB600 million (or $87.4 million), and one of Sohu’s buildings, which serves as Sohu’s corporate headquarters, was released from the pledge. In April 2018, Sohu repaid all of the outstanding balance under the loan arrangements with Ping An Bank and the other building of Sohu was released from the pledge. As of December 31, 2018 and December 31, 2017, the total outstanding balance of the loan was nil and RMB400 million (or $58.3 million), respectively.
In September 2017, Sohu entered into credit agreements with ICBC pursuant to which Sohu was entitled to borrow from ICBC from time to time until March 31, 2018 up to a combined aggregate of RMB800 million (or $116.6 million). The loan is secured by the pledge of Sohu’s building which serves as Sohu’s corporate headquarters in Beijing. Interest accrues on the principal amounts of the loans outstanding at an annual rate equal to the Loan Prime Rate (“LPR”) published by the National Interbank Funding Center, plus 1.2%. The outstanding principal amount of the loan will be payable in four equal installments, with the first installment payable 18 months after the drawdown and the other three installments payable semi-annually at the end of each of the three successive six-month periods after the first installment payment. As of December 31, 2018 and December 31, 2017, the total outstanding balance of the loan was RMB800 million (or $116.6 million) and RMB800 million (or $116.6 million), respectively. As of December 31, 2018, RMB400 million (or $58.3 million) was classified as a short-term bank loan and RMB400 million (or $58.3 million) was classified as a long-term bank loan based on the loan’s repayment terms.
In April 2018, Sohu entered into credit agreements with CMB pursuant to which Sohu was entitled to borrow from CMB from time to time until March 22, 2021 up to an aggregate of RMB700 million (or approximately $102.0 million)(the “CMB Loan”). In April, 2018, Sohu made an initial drawdown under the CMB Loan with a term of 12 months in the amount of RMB400 million (or $58.3 million) (the “First Drawdown”). The proceeds of the First Drawdown were used to repay in full the outstanding balance and all accrued and unpaid interest under credit agreements between Sohu and Ping An Bank. The CMB Loan was secured by a pledge of Sohu’s building, which was released from the pleage after Ping An Bank received such repayment. Interest accrued on the outstanding principal balance at a rate of 6% per year. The outstanding principal amount of the First Drawdown is due in April, 2019. In June, 2018, Sohu made a drawdown under the CMB Loan with a term of 24 months in the amount of RMB300 million (or approximately $43.7 million) (the “Subsequent Drawdown”). Interest accrued on the outstanding principal balance at a rate of 6% per year. The outstanding principal amount of the Subsequent Drawdown is payable in four installments, with the first installment of RMB45 million (or $6.7 million) having been paid in December 2018, and the other three installments payable semi-annually at the end of each of the three successive six-month periods after the first installment payment. As of December 31, 2018, the total outstanding balance of the CMB loan was RMB655 million (or $95.4 million). As of December 31, 2018, RMB490 million (or $71.4 million) was classified as short-term bank loans and RMB165 million (or $24.1 million) was classified as long-term bank loans based on the loans’ repayment terms. Long-term Payables Long-term payables mainly consists of long-term accounts payable, long-term bank loans, long-term tax liabilities and deferred tax liabilities (see Note 14). Long-term accounts payable are financial liabilities with carrying values that approximate fair value due to any changes in fair value, after considering the discount rate, being immaterial. For long-term accounts payable, the Group estimated fair values using the discounted cash flow method, which is unobservable in the market. The Sohu Group classifies the valuation technique as Level 2 of fair value measurements.
Assets Measured at Fair Value on a Nonrecurring Basis The following table sets forth assets measured at fair value on a nonrecurring basis by level within the fair value hierarchy as of December 31, 2017 and 2018 (in thousands)
Purchased Video Content Recorded in Prepaid and Other Assets The impairment losses recognized in prepaid and other assets were mainly due to impairment losses for Sohu Video’s purchased video content. See Note 13 - Intangible Assets, Net. Intangible Assets Intangible assets mainly comprise purchased video content, operating rights for licensed games, domain names and trademarks, computer software, and developed technologies. The impairment losses recognized for intangible assets were mainly due to impairment losses for Sohu Video’s purchased video content. See Note 13 - Intangible Assets, Net. Goodwill Goodwill represents the excess of the purchase price over the fair value of the identifiable assets and liabilities acquired as a result of the Group’s acquisitions of interests in its subsidiaries and consolidated VIEs. The impairment losses recognized for goodwill were mainly due to the 17173.com Website. See Note 12 - Goodwill.

12. GOODWILL Changes in the carrying value of goodwill by segment are as follows (in thousands):
There was one reporting unit under the Sohu segment and one reporting unit under the Sogou segment. The reporting units under the Changyou segment consisted of the Changyou online game business, the 17173.com Website, RaidCall, and the cinema advertising business. In the fourth quarter of 2018, the Sohu Group tested goodwill for impairment at the reporting unit level. The Group performed impairment tests using the qualitative and quantitative methods. For the Sohu and Sogou segments, impairment tests were conducted by quantitatively comparing the fair values of the reporting units to their carrying amounts. The Sohu and Sogou segments estimated the fair values by weighting the results from the income approach and market approach. The valuation approach considers a number of factors that include expected future cash flows, growth rates, discount rates, and market price, and requires Sohu and Sogou to make certain assumptions and estimates regarding industry economic factors and future profitability of the business. For the Changyou segment, Changyou first qualitatively assessed whether it was more likely than not that the fair values of the reporting segments were less than their carrying amounts. For those reporting units where it was more likely than not that their fair values were less than their carrying amounts, Changyou performed the first step of a two-step quantitative goodwill impairment test. Changyou estimated the fair values using the income approach considering factors that included expected future cash flows, growth rates and discount rates.
In the fourth quarter of 2018, Changyou recognized a $16.4 million impairment loss for goodwill relating to the 17173.com Website, primarily due to (i) the launch of new initiatives for the 17173.com Website having fallen behind schedule in the fourth quarter of 2018 and the profit outlook for the 17173.com Website being uncertain, and (ii) the relevant Chinese authority’s temporary suspension between April and December of 2018 of its review of, and issuance of publishing and authorization codes for, online games, which resulted in declines in the number of new games launched and the related demand from game developers and operators for online advertising services on the 17173.com Website, both of which Changyou’s management determined had a material adverse impact on Changyou’s ability to generate revenues and net income from the 17173.com Website. As of December 31, 2018, for the Sohu and Sogou segments, and the businesses in the Changyou segment other than the 17173.com Website, management concluded that the fair values of the reporting units exceeded their carrying values, indicating that the goodwill of the reporting units was not impaired. In the third quarter of 2017, due to reinforced restrictions Chinese regulatory authorities imposed on online card and board games, some of Changyou’s key distribution partners informed Changyou that they had decided to stop the distribution and promotion of card and board games in the third quarter of 2017, which had an adverse impact on MoboTap’s performance, and also increased the uncertainty for its future operations and cash flow. As a result, Changyou determined that it was unlikely that MoboTap would gain users and grow its online card and board games revenues in China, Changyou management performed an impairment test in the third quarter of 2017 using the discounted cash flow method, and an impairment loss of $83.5 million was recognized for goodwill to reflect the fair value of the MoboTap business. Changyou sold MoboTap in March 2018. |

| Intangible Assets, Net | 13. INTANGIBLE ASSETS, NET The following table summarizes the Sohu Group’s intangible assets, net, as of December 31, 2017 and 2018 (in thousands):
Impairment Losses In 2018, Sohu recognized $10.4 million in losses related to Sohu Video’s purchased video content, of which $9.8 million was recognized as impairment of intangible assets and $0.6 million was recognized as impairment of prepaid and other current assets, as Sohu Video’s revenues for 2018 did not meet management’s expectations.
In 2017, Sohu recognized $70.6 million in losses related to Sohu Video’s purchased video content, of which $43.1 million was recognized as impairment of intangible assets and $27.5 million was recognized as impairment of prepaid and other current assets. The impairment losses incurred were mainly due to Sohu Video’s restructuring of its sales team and a strategy shift from purchasing expensive head content to self-producing content, as a result, revenues for 2017 did not meet management’s expectations. Also in 2017, Changyou recognized a $3.4 million impairment loss related to intangible assets for its MoboTap business, mainly due to reinforced restrictions that Chinese regulatory authorities imposed on online card and board games, which had an adverse impact on MoboTap’s current performance, and also increased the uncertainty for its future operations and cash flow. In 2016, the Group recognized $22.9 million in losses for impairment related to Sohu Video’s purchased video content and Changyou purchased content and license rights to games. Impairment losses recognized consisted primarily of impairment losses incurred by Sohu of $18.6 million, including $2.9 million for intangible assets and $15.7 million for prepaid and other current assets, mainly due to the restructuring of the sales team of Sohu Video, which had an adverse impact on Sohu Video’s performance for 2016 and resulted in a lowering of management’s expectations of the programming usefulness of certain Sohu Video’s purchased video content. Amortization In 2018, 2017 and 2016, amortization of intangible assets was $59.4 million, $140.7 million and $131.2 million, respectively. As of December 31, 2018, amortization expenses for future periods are estimated to be as follows:

Income Tax PRC Corporate Income Tax The majority of the subsidiaries and VIEs of the Sohu Group are based in mainland China and are subject to income taxes in the PRC. These China-based subsidiaries and VIEs conduct substantially all of the Sohu Group’s operations, and generate most of the Sohu Group’s income or losses. The CIT Law applies an income tax rate of 25% to all enterprises but grants preferential tax treatment to HNTEs, “Software Enterprises,” and KNSEs. Principal Entities Qualified as HNTEs Under preferential tax treatment, HNTEs can enjoy an income tax rate of 15%, but need to re-apply every three years. During this three-year period, an HNTE must conduct a qualification self-review each year to ensure it meets the HNTE criteria and is eligible for the 15% preferential tax rate for that year. If an HNTE fails to meet the criteria for qualification as an HNTE in any year, the enterprise cannot enjoy the 15% preferential tax rate in that year, and must instead use the regular 25% CIT rate. As of December 31, 2018, the following principal entities of the Sohu Group were qualified as HNTEs and were entitled to an income tax rate of 15%. For Sohu’s Business
For Sogou’s Business
For Changyou’s Business
Principal Entities Qualified as Software Enterprises and KNSEs The CIT Law and its implementing regulations provide that a Software Enterprise is entitled to an income tax exemption for two years beginning with its first profitable year and a 50% reduction to a rate of 12.5% for the subsequent three years. An entity that qualifies as a KNSE is entitled to a further reduced preferential income tax rate of 10%. Enterprises wishing to enjoy the status of a Software Enterprise or a KNSE must perform a self-assessment each year to ensure they meet the criteria for qualification and file required supporting documents with the tax authorities before using the preferential CIT rates. These enterprises will be subject to the tax authorities’ assessment each year as to whether they are entitled to use the relevant preferential CIT treatments. If at any time during the preferential tax treatment years an enterprise uses the preferential CIT rates but the relevant authorities determine that it fails to meet applicable criteria for qualification, the relevant authorities may revoke the enterprise’s Software Enterprise/KNSE status.

U.S. Corporate Income Tax Sohu.com Inc., which was formerly the top-tier publicly-traded parent company of the Sohu Group, was dissolved and liquidated on May 31, 2018. Sohu.com Inc. was a Delaware corporation that was subject to U.S. corporate income tax on its taxable income at a rate of 21% for taxable years beginning after December 31, 2017 and of up to 35% for prior tax years. U.S. federal tax legislation signed into law on December 22, 2017, commonly referred to as the Tax Cuts and Jobs Act (the “U.S. TCJA”), significantly modified the U.S. Internal Revenue Code by, among other things, reducing the maximum statutory U.S. federal corporate income tax rate from 35% to 21% for taxable years beginning after December 31, 2017; limiting and/or eliminating many business deductions; migrating the U.S. to a partial territorial tax system with a one-time Toll Charge on a mandatory deemed repatriation of previously deferred foreign earnings of certain foreign subsidiaries; subject to certain limitations, generally eliminating U.S. corporate income tax on dividends from foreign subsidiaries; and providing for new taxes on certain foreign earnings. Certain activities conducted in the PRC resulted in U.S. corporate income taxes being imposed on Sohu.com Inc. when its subsidiaries that were controlled foreign corporations (“CFCs”) generated income that was subject to Subpart F of the U.S. Internal Revenue Code (“Subpart F”). Generally, passive income, such as rents, royalties, interest, dividends, and gains from disposal of the company’s investments, is among the types of income subject to taxation under Subpart F. Any income taxable under Subpart F was taxable in the U.S. at a federal corporate income tax rate of 21%. Subpart F income also included certain income from intra-Group transactions between Sohu.com Inc.’s non-U.S. subsidiaries and VIEs and Changyou’s non-U.S. subsidiaries and VIEs or Sogou’s non-U.S. subsidiaries and VIEs, or where Sohu.com Inc.’s non-U.S. subsidiaries or VIEs made an “investment in U.S. property,” such as holding the stock in, or making a loan to, a U.S. corporation. To the extent that portions of Sohu.com Inc.’s U.S. taxable income, such as Subpart F income or GILTI, had been determined to be from sources outside of the U.S., subject to certain limitations, Sohu.com Inc. could claim foreign tax credits to offset its U.S. income tax liabilities. Following the enactment of the U.S. TCJA, if dividends that Sohu.com Inc. received from its subsidiaries after January 1, 2018 were determined to be from sources outside of the U.S., subject to certain limitations, Sohu.com Inc. would generally not have been required to pay U.S. corporate income tax on those dividends. Liabilities for U.S. corporate income tax were accrued in the Company’s consolidated statements of comprehensive income and estimated tax payments were made when required by U.S. law. Treatment of Toll Charge Related to the U.S. TCJA Beginning in the fourth quarter of 2017, the Sohu Group had recognized a provisional amount of income tax expense for the Toll Charge of $219 million, which represented management’s estimate of the amount of the Toll Charge that would have been payable by Sohu.com Inc. based on the deemed repatriation to the United States of its share of previously deferred earnings of certain of its non-U.S. subsidiaries, offset by a reduction of $4 million in liability for deferred U.S. income tax, as a result of the U.S. TCJA. The Sohu Group included the provisional amount of the Toll Charge of $219 million in its interim financial statements through the quarter ended September 30, 2018, in reliance on SAB 118. For the fourth quarter of 2018, the Sohu Group’s management re-evaluated the impact on the Sohu Group of the Toll Charge under the U.S. TCJA. Management determined that it was more likely than not, based on the technical merits, that the tax position that the Sohu Group had no Toll Charge liability would be sustained. The Group recognized a tax benefit in the amount of $77 million, which was the largest amount that management determined to be greater than 50% likely to be realized upon settlement with the U.S. IRS. As a result, as of December 31, 2018 the Sohu Group had an unrecognized tax benefit in the amount of $142 million, which represented the difference between the tax benefit recognized in the fourth quarter of 2018 and management’s previous estimate of the Toll Charge. In addition, the Sohu Group accrued $2 million in interest on the unrecognized tax benefit. The tax benefit recognized and the unrecognized tax benefit in relation to the Toll Charge may be subject to further adjustment in subsequent periods based on facts and circumstances that arose after December 31, 2018, such as final IRS Toll Charge regulations published in February 2019, and any future circumstances such as any guidance issued by the U.S. Department of the Treasury, any U.S. IRS challenge of the Group’s position on the Toll Charge, if any, and management’s further judgment and estimates.
Cayman Island Tax Under the current tax laws of the Cayman Islands, the Group is not subject to tax on its income or capital gains. In addition, no Cayman Islands withholding tax will be imposed upon the payment of dividends by the Group to its shareholders. Hong Kong Tax The Group’s subsidiaries incorporated in Hong Kong are subject to profits tax in Hong Kong at the rate of 16.5% for each of the years ended December 31, 2016, 2017 and 2018. Composition of Income Tax Expense Sohu.com Inc., which was the former top-tier entity of the Sohu Group, was a Delaware corporation that was subject to United States income tax. On May 31, 2018, Sohu.com Inc. was dissolved and liquidated and Sohu.com Limited became the top-tier entity of the Sohu Group. Sohu.com Limited is not subject to income or capital gains tax under the current laws of the Cayman Islands. There are no other taxes likely to be material to Sohu.com Limited levied by the government of the Cayman Islands. The components of income before income taxes are as follows (in thousands):
For the fourth quarter of 2018, the Sohu Group’s management re-evaluated the impact on the Sohu Group of the Toll Charge under the U.S. TCJA. Management determined that it was more likely than not, based on the technical merits, that the tax position that the Sohu Group had no Toll Charge liability would be sustained. The Group recognized a tax benefit in the amount of $77 million, which was the largest amount that management determined to be greater than 50% likely to be realized upon settlement with the U.S. IRS. As a result, as of December 31, 2018 the Sohu Group had an unrecognized tax benefit in the amount of $142 million, which represented the difference between the tax benefit recognized in the fourth quarter of 2018 and management’s previous estimate of the Toll Charge. In addition, the Sohu Group accrued $2 million in interest on the unrecognized tax benefit. In 2017, of the $273.1 million income tax expense, $57.8 million was for PRC tax, mainly attributable to the Sohu Group’s business operations, and $214.7 million was for U.S. corporate income tax, resulting primarily from the Company’s recognition in the fourth quarter of 2017 of $219 million for the Toll Charge, which represented management’s estimate of the amount of the Toll Charge that would have been payable by Sohu.com Inc. based on the deemed repatriation to the United States of Sohu.com Inc.’s share of previously deferred earnings of certain non-U.S. subsidiaries of Sohu.com Inc., offset by a reduction of $4 million in liability for deferred U.S. income tax as a result of the U.S. TCJA. See “Treatment of Toll Charge Related to the U.S. TCJA” above. The combined effects of the income tax exemption and reduction available to the Group are as follows (in thousands, except per share data):
Effective Tax Rate The CIT Law applies an income tax rate of 25% to all enterprises, but grants preferential tax treatment to HNTEs, Software Enterprises, and KNSEs. The U.S. TCJA significantly modified the U.S. Internal Revenue Code by, among other things, reducing the statutory U.S. federal corporate income tax rate from 35% to 21% for taxable years beginning after December 31, 2017; limiting and/or eliminating many business deductions; migrating the U.S. to a territorial tax system with a one-time Toll Charge on a mandatory deemed repatriation of previously deferred foreign earnings of certain foreign subsidiaries; subject to certain limitations, generally eliminating U.S. corporate income tax on dividends from foreign subsidiaries; and providing for new taxes on certain foreign earnings. The following is reconciliation between the statutory rate and the Group’s effective tax rate. For 2016 and 2017, the statutory rate represented the U.S. statutory rate of 35%, and for 2018, the statutory rate represented the PRC statutory rate of 25%. The table does not reflect any accruals related to the Toll Charge. See “U.S. Corporate Income Tax” and “Treatment of Toll Charge Related to the U.S. TCJA.”
Note (1): The reversal of income tax for preferential income tax rates that Changyou’s and Sogou’s subsidiaries and VIEs were entitled to as KNSEs or Software Enterprises for 2016, 2017 and 2018 was included in the “Effect of tax holidays applicable to subsidiaries and consolidated VIEs” in the above table. Note (2): The change was mainly due to additional income withholding tax of $47 million that was recognized in the first quarter of 2018 due to a revised policy for Changyou’s PRC subsidiaries with respect to their distribution of cash dividends. The revised policy was adopted to facilitate the distribution of a special cash dividend in the aggregate amount of approximately $500.0 million that was declared by Changyou’s Board of Directors on April 5, 2018. PRC Withholding Tax on Dividends The CIT Law imposes a 10% withholding income tax on dividends distributed by foreign invested enterprises in the PRC to their immediate holding companies outside Mainland China. A lower withholding tax rate may be applied if there is a tax treaty between Mainland China and the jurisdiction of the foreign holding company. A holding company in Hong Kong, for example, will be subject to a 5% withholding tax rate under an arrangement between the PRC and the Hong Kong Special Administrative Region on the “Avoidance of Double Taxation and Prevention of Fiscal Evasion with Respect to Taxes on Income,” if such holding company is considered a non-PRC resident enterprise and holds at least 25% of the equity interests in the PRC foreign invested enterprise distributing the dividends, subject to approval of the PRC local tax authority. However, if the Hong Kong holding company is not considered to be the beneficial owner of such dividends under applicable PRC tax regulations, such dividend will remain subject to a withholding tax rate of 10%. Before 2018, in order to fund the distribution of a dividend to shareholders of the Sohu Group’s majority-owned subsidiary Changyou, Changyou’s management determined to cause one of its PRC subsidiaries to declare and distribute a cash dividend of all of its stand-alone 2012 earnings and half of its stand-alone subsequent years’ earnings to its direct overseas parent company, Changyou HK, and adopted as a policy for such subsequent years for its PRC subsidiaries a limit on payment of dividends to their direct overseas parent companies of one-half of such PRC subsidiaries’ earnings. In 2018, in order to facilitate the distribution of a special cash dividend of $500.0 million declared by Changyou’s board of directors on April 5, 2018, Changyou revised its policy for its PRC subsidiaries with respect to their distribution of cash dividends. Under the revised policy, all of Changyou’s PRC subsidiaries (not including Changyou’s VIEs and their subsidiaries) will be able to distribute their cumulative available and undistributed earnings to their direct overseas parent companies in future periods. The change resulted in Changyou’s accrual of additional withholding income taxes of approximately $47 million for the period before December 31, 2017, which was recognized in the Sohu Group’s consolidated financial statements for the quarter ended March 31, 2018. As of December 31, 2018, the Sohu Group had accrued deferred tax liabilities related to Changyou in the amount of $79.8 million for PRC withholding tax.
With the exception of that dividend, the Sohu Group does not intend to have any of its PRC subsidiaries or VIEs distribute any undistributed profits of such subsidiaries or VIEs to their direct overseas parent companies, but rather intends that such profits will be permanently reinvested by such subsidiaries and VIEs for their PRC operations. As of December 31, 2018, the total amount of undistributed profits from the PRC subsidiaries and VIEs for which no withholding tax had been accrued was $2.45 billion, and the unrecognized tax liabilities were $245.1 million. PRC Value-Added Tax On May 1, 2016, the transition from the imposition of PRC business tax to the imposition of VAT was expanded to all industries in China, and as a result all of the Sohu Group’s revenues have been subject to VAT since that date. To record VAT payable, the Group adopted the net presentation method, which presents the difference between the output VAT (at rates of 6% or 17% for the years ended December 31, 2016 and 2017 and for the period from January 1, 2018 to April 30, 2018, and at rates of 6% or 16% after May 1, 2018) and the available input VAT amount (at the rate applicable to the supplier). Deferred Tax Assets and Liabilities Significant components of the Group’s deferred tax assets and liabilities consist of the following (in thousands):
Net deferred tax assets are recorded under other assets in the consolidated balance sheets. As of December 31, 2018, the Group had net operating losses from PRC entities of approximately $1.24 billion available to offset against future net profit for income tax purposes. The Group anticipates that it is more likely than not that these net operating losses may not be utilized based on its estimate of the operation performance of these PRC entities; therefore, $264.5 million in deferred tax assets generated from net operating losses were offset by a valuation allowance. The following table sets forth the movement of the valuation allowances for deferred tax assets for the years presented (in thousands):
In 2018, $14.8 million of PRC net operating losses generated from previous years expired. Pursuant to a public announcement issued by the PRC State Administration of Taxation in August 2018, net operating losses of entities not qualified as HNTEs will expire between 2019 and 2023 if not utilized and those of entities qualified as HNTEs will expire in 2028. Uncertain Tax Positions The following table summarizes the Group’s unrecognized tax benefit from January 1, 2016 to December 31, 2018 (in thousands):
The increase in 2018 was mainly due to an unrecognized tax benefit in the amount of $142 million, which represented the difference between the tax benefit recognized in the fourth quarter of 2018 in relation to the Toll Charge and management’s previous estimate of the Toll Charge that would have been due by Sohu.com Inc. if it had not been dissolved and liquidated on May 31, 2018. The Group recognized interest in the amount of $2 million in connection with the unrecognized tax benefit for the year ended December 31, 2018. The Group did not have any significant penalties associated with tax positions for the year ended December 31, 2018. In 2017, the decreases related to prior year tax positions mainly represented write-offs of $2.4 million related to uncertain tax positions generated in 2009 and 2013. The material jurisdictions in which the Group is subject to potential examination include China and the United States. In general, the PRC tax authorities have up to five years, and the U.S. IRS has up to three years and in certain cases up to six years, to conduct examinations of the tax filings of the Group. |

| Commitments and Contingencies | 15. COMMITMENTS AND CONTINGENCIES Commitments The following table sets forth the Group’s commitments as of December 31, 2018 (in thousands):
Note (1): For the years ended December 31, 2018, 2017 and 2016, rental expense included in the operating lease was approximately $24.7 million, $23.9 million, and $23.9 million, respectively.
Litigation The Sohu Group is a party to various litigation matters which it considers routine and incidental to its business. The Sohu Group records a liability when the likelihood of an unfavorable outcome is probable and the amount of loss can be reasonably estimated. The Sohu Group evaluates, on a regular basis, developments in litigation matters that could affect the amount of liability that has been previously accrued and makes adjustments as appropriate. Management believes that the total liabilities to the Sohu Group that may arise as a result of currently pending legal proceedings will not have a material adverse effect on the Group’s business, results of operations, financial condition and cash flows. Sogou is currently involved in several lawsuits in PRC courts where its competitors instituted proceedings or asserted counterclaims against the Sogou or the Sogou instituted proceedings or asserted counterclaims against its competitors. There are also four putative class action lawsuits that have been filed against Sogou in the United States, three in a State court in the State of California and one in the United States District Court for the Southern District of New York, that allege violations of U.S. securities laws in connection with Sogou’s IPO in 2017. As of December 31, 2018, Sohu and Changyou had no significant litigation contingencies, and Sogou had recorded estimated liabilities of $3.4 million for litigation contingencies as a component of accrued liabilities related to its currently pending proceedings. PRC Law and Regulations The Chinese market in which the Sohu Group operates poses certain macro-economic and regulatory risks and uncertainties. These uncertainties extend to the ability to operate an Internet business and to conduct brand advertising, search and search-related advertising, online game, and other services in the PRC. Though the PRC has, since 1978, implemented a wide range of market-oriented economic reforms, continued reforms and progress towards a full market-oriented economy are uncertain. In addition, the telecommunication, information, and media industries remain highly regulated. Restrictions are currently in place and are unclear with respect to which segments of these industries foreign-owned entities, like the Sohu Group, may operate. The Chinese government may issue from time to time new laws or new interpretations of existing laws to regulate areas such as telecommunication, information and media. The Sohu Group’s legal structure and scope of operations in China could be subject to restrictions, which could result in limits on its ability to conduct business in the PRC. Certain risks related to PRC law that could affect the Sohu Group’s VIE structure are discussed in Note 16 - VIEs. Regulatory risks also encompass interpretation by PRC tax authorities of current tax law, including the applicability of certain preferential tax treatments. The Sohu Group’s sales, purchase and expense transactions are generally denominated in RMB and a significant portion of its assets and liabilities are denominated in RMB. The RMB is not freely convertible into foreign currencies. In China, foreign exchange transactions are required by law to be transacted only by authorized financial institutions. Remittances in currencies other than RMB by its subsidiaries in China may require certain supporting documentation in order to effect the remittance. |

| VIEs |
Background PRC laws and regulations prohibit or restrict foreign ownership of companies that operate Internet information and content, Internet access, online games, mobile, value added telecommunications and certain other businesses in which the Sohu Group is engaged or could be deemed to be engaged. Consequently, the Sohu Group conducts certain of its operations and businesses in the PRC through its VIEs. The Sohu Group consolidates in its consolidated financial statements all of the VIEs of which the Group is the primary beneficiary. VIEs Consolidated within the Sohu Group The Sohu Group adopted the guidance of accounting for VIEs, which requires VIEs to be consolidated by the primary beneficiary of the entity. Management made evaluations of the relationships between the Sohu Group and its VIEs and the economic benefit flow of contractual arrangements with the VIEs. In connection with such evaluation, management also took into account the fact that, as a result of contractual arrangements with its consolidated VIEs, the Sohu Group controls the shareholders’ voting interests in those VIEs. As a result of such evaluation, the management concluded that the Sohu Group is the primary beneficiary of the VIEs which the Group consolidates. All of the consolidated VIEs are incorporated and operated in the PRC, and the Group’s principal VIEs are directly or indirectly owned by Dr. Charles Zhang, the Sohu Group’s Chairman and Chief Executive Officer, or other executive officers and employees of the Sohu Group identified below. Capital for the consolidated VIEs was funded by the Sohu Group through loans provided to Dr. Charles Zhang and other executive officers and employees, and was initially recorded as loans to related parties. These loans are eliminated for accounting purposes against the capital of the VIEs upon consolidation. Under contractual agreements with the Sohu Group, Dr. Charles Zhang and those other executive officers and employees of the Sohu Group who are shareholders of the consolidated VIEs are required to transfer their ownership in these entities to the Group, if permitted by PRC laws and regulations, or, if not so permitted, to designees of the Group at any time as requested by the Group to repay the loans outstanding. All voting rights of the consolidated VIEs are assigned to the Sohu Group, and the Group has the right to designate all directors and senior management personnel of the consolidated VIEs, and also has the obligation to absorb losses of the consolidated VIEs. Dr. Charles Zhang and those other executive officers and employees of the Sohu Group who are shareholders of the consolidated VIEs have pledged their shares in the consolidated VIEs as collateral for the loans. As of December 31, 2018, the aggregate amount of these loans was $7.7 million.
Under its contractual arrangements with the consolidated VIEs, the Sohu Group has the power to direct activities of the VIEs, and can have assets transferred freely out of the VIEs without any restrictions. Therefore, the Group considers that there is no asset of a consolidated VIE that can be used only to settle obligations of the VIEs, except for registered capital and PRC statutory reserves of the VIEs. As of December 31, 2018, the registered capital and PRC statutory reserves of the consolidated VIEs totaled $65.2 million. As all of the consolidated VIEs are incorporated as limited liability companies under the PRC Company Law, creditors of the consolidated VIEs do not have recourse to the general credit of the Sohu Group for any of the liabilities of the consolidated VIEs. Currently there is no contractual arrangement that could require the Sohu Group to provide additional financial support to the consolidated VIEs. As the Sohu Group is conducting certain business in the PRC mainly through the consolidated VIEs, the Group may provide such support on a discretionary basis in the future, which could expose the Group to a loss. The Sohu Group classified the consolidated VIEs within the Sohu Group as principal VIEs or immaterial VIEs based on certain criteria, such as the VIEs’ total assets or revenues. The following is a summary of the principal VIEs within the Sohu Group: Basic Information for Principal VIEs and Subsidiaries of Principal VIEs For Sohu’s Business - High Century High Century was incorporated in 2001.

Each agreement terminates only when AmazGame or Gamespace, as the case may be, is dissolved. Certain of the contractual arrangements described above between the VIEs and the related wholly-owned subsidiaries of the Sohu Group are silent regarding renewals. However, because the VIEs are controlled by the Sohu Group through powers of attorney granted to the Sohu Group by the shareholders of the VIEs, the contractual arrangements can be, and are expected to be, renewed at the subsidiaries’ election. VIE-Related Risks It is possible that the Sohu Group’s operation of certain of its operations and businesses through VIEs could be found by PRC authorities to be in violation of PRC law and regulations prohibiting or restricting foreign ownership of companies that engage in such operations and businesses. If a finding were made by PRC authorities that the Sohu Group’s operation of certain of its operations and businesses through VIEs is prohibited, regulatory authorities with jurisdiction over the licensing and operation of such operations and businesses would have broad discretion in dealing with such a violation, including levying fines, confiscating the Sohu Group’s income, revoking the business or operating licenses of the affected businesses, requiring the Sohu Group to restructure its ownership structure or operations, or requiring the Sohu Group to discontinue all or any portion of its operations. Any of these actions could cause significant disruption to the Sohu Group’s business operations, and have a severe adverse impact on the Sohu Group’s cash flows, financial position, and operating performance. The Sohu Group’s management considers the possibility of such a finding by PRC regulatory authorities to be remote. In addition, it is possible that the contracts among the Sohu Group, the Sohu Group’s VIEs and shareholders of its VIEs would not be enforceable in China if PRC government authorities or courts were to find that such contracts contravene PRC law and regulations or are otherwise not enforceable for public policy reasons. In the event that the Sohu Group was unable to enforce these contractual arrangements, the Sohu Group would not be able to exert effective control over the affected VIEs. Consequently, such VIEs’ results of operations, assets and liabilities would not be included in the Sohu Group’s consolidated financial statements. If such were the case, the Sohu Group’s cash flows, financial position and operating performance would be severely adversely affected. The Sohu Group’s contractual arrangements with respect to its consolidated VIEs are in place. The Sohu Group’s management believes that such contracts are enforceable, and considers the possibility remote that PRC regulatory authorities with jurisdiction over the Sohu Group’s operations and contractual relationships would find the contracts to be unenforceable. The Sohu Group’s operations and businesses rely on the operations and businesses of its VIEs, which hold certain recognized and unrecognized revenue-producing assets. The recognized revenue-producing assets include goodwill and intangible assets acquired through business acquisitions. Goodwill primarily represents the expected synergies from combining an acquired business with the Sohu Group. Intangible assets acquired through business acquisitions mainly consist of customer relationships, non-compete agreements, user bases, copyrights, trademarks and developed technologies. Unrecognized revenue-producing assets mainly consist of licenses and intellectual property. Licenses include operations licenses, such as Internet information service licenses and licenses for providing content. Intellectual property developed by the Sohu Group mainly consists of patents, copyrights, trademarks, and domain names. The Sohu Group’s operations and businesses may be adversely impacted if the Sohu Group loses the ability to use and enjoy assets held by these VIEs. |

Summary of the Company’s outstanding shares (in thousands):
Share Incentive Plans Sohu (excluding Sohu Video), Sogou, Changyou, and Sohu Video have incentive plans for the granting of share-based awards, including options and restricted share units, to their directors, management and other key employees. 1) Sohu.com Limited Share-based Awards Sohu’s 2018 Share Incentive Plan On July 2, 2010, Sohu.com Inc.’s shareholders adopted the 2010 Stock Incentive Plan, which provides for the issuance of up to 1,500,000 shares of Sohu.com Inc.’s common stock, including stock issued pursuant to the vesting and settlement of restricted stock units and pursuant to the exercise of stock options. The maximum term of any share-based award granted under the Sohu 2010 Stock Incentive Plan is ten years from the grant date. On April 2, 2018, Sohu.com Limited adopted the Sohu 2018 Share Incentive Plan, which provides for the issuance of up 1,148,565 ordinary shares of Sohu.com Limited. The Sohu 2018 Share Incentive Plan will expire in April 2028. Upon the dissolution of Sohu.com Inc. on May 31, 2018, Sohu.com Limited assumed all then existing obligations of Sohu.com Inc. with respect to equity incentive awards that had been granted under the Sohu 2010 Stock Incentive Plan and then remained outstanding, and such awards were converted into the right to receive upon exercise or settlement Sohu.com Limited’s ordinary shares under the Sohu 2018 Share Incentive Plan rather than shares of the common stock of Sohu.com Inc., subject to the other terms of such outstanding awards. As of December 31, 2018, 649,405 shares were available for grant under the Sohu 2018 Share Incentive Plan. i) Summary of Share Option Activity In February 2015, May 2016, September 2017 and November 2017, Sohu.com Inc.’s Board of Directors approved contractual grants to members of the Company’s management and key employees of options for the purchase of an aggregate of 1,068,000, 13,000, 32,000 and 6,000 shares of common stock of Sohu.com Inc., respectively, under the Sohu 2010 Stock Incentive Plan, with nominal exercise prices of $0.001, all of which were converted, on May 31, 2018, into the right to receive upon exercise Sohu.com Limited’s ordinary shares under the Sohu 2018 Share Incentive Plan. These share options vest and become exercisable in four equal installments over a period of four years, with each installment vesting upon the satisfaction of a service period requirement and certain subjective performance targets. These share options are substantially similar to restricted share units except for the nominal exercise price, which would be zero for restricted share units. Under ASC 718-10-25 and ASC 718-10-55, no grant date can be established for these options until a mutual understanding is reached between the Company and the recipients clarifying the subjective performance requirements. If the service inception date preceded the grant date, compensation expense should be accrued beginning on the service inception date, and re-measured on each subsequent reporting date before the grant date is established, based on the then-current fair value of the awards. To determine the fair value of these options, the public market price of the underlying shares at each reporting date is used and a binomial valuation model is applied. As of December 31, 2018, 578,500 of these options had been granted and had become vested on their respective vesting dates, as a mutual understanding of the subjective performance targets was reached between the Company and the recipients, the targets had been satisfied, and the service period requirements had been fulfilled. The cumulative share-based compensation expense for these granted options has been adjusted and fixed based on their aggregate fair values, at their respective grant dates, of $22.8 million.
A summary of option activity under the Sohu 2010 Stock Incentive Plan and the Sohu 2018 Share Incentive Plan, as applicable, as of and for the year ended December 31, 2018 is presented below:
Note (1): The aggregated intrinsic value in the preceding table represents the difference between Sohu’s closing ADS price of $17.42 on December 31, 2018 and the nominal exercise price of the options. For the years ended December 31, 2018, 2017 and 2016, total share-based compensation expense recognized for these options was negative $5.1 million, $2.4 million and $1.4 million, respectively. The negative amounts in the tables above resulted from re-measured compensation expense based on the then-current fair value of the awards on the reporting date. For the years ended December 31, 2018, 2017 and 2016, the total fair values of these Sohu options vested on their respective vesting dates were $5.0 million, $7.1 million and $10.8 million, respectively. For the years ended December 31, 2018, 2017 and 2016, the total intrinsic value of options exercised was $6.2 million, $6.1 million and $2.5 million, respectively. ii) Summary of restricted stock unit activity A summary of restricted stock/share unit activity under the Sohu 2010 Stock Incentive Plan and the Sohu 2018 Share Incentive Plan, as applicable, as of and for the year ended December 31, 2018 is presented below:
For the years ended December 31, 2018, 2017 and 2016, total share-based compensation expense recognized for restricted stock/share units was nil, negative $1.7 million and $1.3 million, respectively. As of December 31, 2018, there was nil of unrecognized compensation expense related to unvested restricted stock/share units. The total fair value on their respective vesting dates of restricted stock/share units vested during the years ended December 31, 2018, 2017 and 2016 was nil, $0.3 million and $0.9 million, respectively. 2) Sogou Inc. Share-based Awards Sogou 2010 Share Incentive Plan Sogou adopted a share incentive plan on October 20, 2010 amended the plan effective August 22, 2014 to increase the aggregate number of Sogou Class A Ordinary Shares issuable under the plan to 41,500,000 (as amended to date, the “Sogou 2010 Share Incentive Plan”). Awards of share rights may be granted under the Sogou 2010 Share Incentive Plan to management and other key employees of Sogou and of any present or future parents or subsidiaries or VIEs of Sogou. The maximum term of any share incentive award granted under the Sogou 2010 Share Incentive Plan is ten years from the grant date. The Sogou 2010 Share Incentive Plan will expire on October 19, 2020. The options contractually granted under the Sogou 2010 Share Incentive Plan may be placed in one of the following three categories:
A summary of each of the above three categories of Sogou’s share options as of December 31, 2018 is presented below:
A summary of Sogou share option activity under the Sogou 2010 Share Incentive Plan as of and for the year ended December 31, 2018 is presented below:
Note (1): The aggregate intrinsic values in the preceding table represent the difference between Sogou’s closing price of $5.25 per Class A Ordinary Share on December 31, 2018 and the exercise prices of the share options. For the years ended December 31, 2018, 2017 and 2016, total share-based compensation expense recognized for Sogou share options under the Sogou 2010 Share Incentive Plan was $12.5 million, $23.0 million and $7.6 million, respectively. As of December 31, 2018, there was $6.4 million of unrecognized compensation expense related to unvested Sogou share options. The expense is expected to be recognized over a weighted average period of 1.46 years. For the years ended December 31, 2018, 2017 and 2016, the total intrinsic value of options exercised was $33.2 million, $11.1 million, and $15.2 million, respectively. Prior to the completion of Sogou’s IPO, the fair values of Sogou Class A Ordinary Shares were assessed using the income approach /discounted cash flow method or based on the mid-point of the estimated Sogou IPO price range, in each case with a discount for lack of marketability, because the Sogou Class A Ordinary Shares underlying the award were not publicly traded at the time of grant. The assessment required complex and subjective judgments regarding Sogou’s projected financial and operating results, its unique business risks, the liquidity of its ordinary shares and its operating history and prospects at the time the grants were made. After the completion of Sogou’s IPO, the fair values of the ordinary shares of Sogou were determined based on the market price of Sogou’s ADSs.
The fair value of the Sogou share options granted under the Sogou 2010 Incentive Plan was estimated on the date of grant with the assistance of a qualified professional appraiser, using the binomial valuation model with the following assumptions used:
Sogou estimated the risk-free rate based on the market yields of U.S. Treasury securities with an estimated country-risk differential as of the valuation date. An exercise multiple was estimated as the ratio of the fair value of the Sogou Class A Ordinary Shares over the exercise prices as of the time the options would be expected to be exercised, based on consideration of research studies regarding exercise patterns based on historical statistical data. In Sogou’s valuation analysis, a multiple of three was applied for management and a multiple of two was applied for other key employees. Sogou estimated the forfeiture rate to be 0% or 1% for the Sogou share options granted to Sogou management and 12% for the Sogou share options granted to Sogou’s other key employees. As Sogou’s ordinary shares had been publicly traded for only one year as of December 31, 2018, the expected volatility at the valuation date was estimated based on the historical volatility of specified comparable companies for the periods before the grant dates with length commensurate with the expected term of the Sogou share options. Sogou has no history or expectation of paying dividends on its ordinary shares. Accordingly, the dividend yield was estimated to be 0%. Sogou 2017 Share Incentive Plan In October 2017, Sogou adopted a share incentive plan (the “Sogou 2017 Share Incentive Plan”) which provides that the aggregate number of Sogou Class A Ordinary Shares issuable under the plan is 28,000,000. Share incentive awards may be granted under the Sogou 2017 Share Incentive Plan to Sogou’s management and employees and of any of its present or future parents or subsidiaries. The maximum term of any share incentive award granted under the Sogou 2017 Share Incentive Plan is ten years from the grant date. The options contractually granted under the Sogou 2017 Share Incentive Plan may be placed in one of the following two categories:
A summary of each of the above two categories of Sogou’s share options as of December 31, 2018 is presented below:
A summary of Sogou share option activity under the Sogou 2017 Share Incentive Plan as of and for the year ended December 31, 2018 is presented below:
Note (1): The aggregate intrinsic value in the preceding table represents the difference between the Sogou’s closing price of $5.25 per Class A Ordinary Shares on December 31, 2018 and the exercise prices of the share options. For the years ended December 31, 2018, total share-based compensation expense recognized for Sogou share options under the Sogou 2017 Share Incentive Plan was $1.6 million. As of December 31, 2018 there was $4.0 million of unrecognized compensation expense related to unvested Sogou share options. The expense is expected to be recognized over a weighted average period of 2.12 years. The method used to determine the fair value of the Sogou share options granted under the Sogou 2017 Share Incentive Plan was the same as the method used for the share options granted under the Sogou 2010 Incentive Plan as described above, except for the assumptions used in the binomial valuation model as presented below:
Sohu Management Sogou Share Option Arrangement Under an arrangement (the “Sohu Management Sogou Share Option Arrangement”) that was approved by the boards of directors of Sohu and Sogou in March 2011, Sohu has the right to provide to members of Sohu’s Board of Directors, management and other key employees of the Sohu, and certain members of management and other key employees of Sogou the opportunity to purchase from Sohu up to 12,000,000 Sogou Class A Ordinary Shares at a fixed exercise price of $0.625 or $0.001 per share. Of these 12,000,000 Sogou Class A Ordinary Shares, 8,800,000 are Sogou Class A Ordinary Shares previously held by Sohu and 3,200,000 are Sogou Class A Ordinary Shares that were newly-issued on April 14, 2011 by Sogou to Sohu at a price of $0.625 per share, or a total of $2.0 million. As of December 31, 2018, Sohu had contractually granted options for the purchase of 8,305,000 Sogou Class A Ordinary Shares under the Sohu Management Sogou Share Option Arrangement. The options contractually granted under the Sohu Management Sogou Share Option Arrangement may be placed in one of the following two categories:
A summary of the above two categories of Sogou’s share options as of December 31, 2018 is presented below:
A summary of Sogou share option activity under the Sohu Management Sogou Share Option Arrangement as of and for the year ended December 31, 2018 is presented below:
Note (1): The aggregate intrinsic values in the preceding table represent the difference between Sogou’s closing price of $5.25 per Class A ordinary share on December 31, 2018 and the exercise prices of the options. For the years ended December 31, 2018, 2017 and 2016, total share-based compensation expense recognized for Sogou share options under the Sohu Management Sogou Share Option Arrangement was nil, nil and $0.4 million, respectively. As of December 31, 2018, there was no unrecognized compensation expense related to unvested Sogou share options. For the years ended December 31, 2018, 2017 and 2016, the total fair values of the Sogou share options under the Sohu Management Sogou Share Option Arrangement vested on their respective vesting dates were nil, nil, and $0.5 million, respectively. For the years ended December 31, 2018, 2017 and 2016, total intrinsic value of options exercised was nil, $0.2 million, and $4.5 million, respectively. The method used to determine the fair value of Sogou share options granted under the Sohu Management Sogou Share Option Arrangement was the same as the method used for the Sogou share options granted under the Sogou 2010 Incentive Plan as described above, except for the assumptions used in the binomial valuation model as presented below. There was no share-based compensation expense recognized under the Sohu Management Sogou Share Option Arrangement for the year ended December 31, 2017 and 2018.
Option Modification In the first and second quarter of 2013, a portion of the Sogou share options granted under the Sogou 2010 Share Incentive Plan and the Sohu Management Sogou Share Option Arrangement were exercised early, and the resulting Sogou ordinary shares were transferred to trusts with the original option grantees as beneficiaries. The trusts will distribute the Sogou ordinary shares to those beneficiaries in installments based on the vesting requirements under the original option agreements. Although these trust arrangements caused a modification of the terms of these Sogou share options, the modification was not considered substantive. Accordingly, no incremental fair value related to these Sogou ordinary shares resulted from the modification, and the remaining share-based compensation expense for these Sogou ordinary shares continued to be recognized over the original remaining vesting period.
As of December 31, 2018, 6,405,000 Sogou Class A Ordinary Shares that were purchased upon the early exercise of options granted under the Sogou 2010 Share Incentive Plan remained unvested in accordance with the vesting requirements under the original option agreements. All Sogou Class A Ordinary Shares issued upon such early exercise that have become vested have been included in the disclosures under the headings “Sogou 2010 Share Incentive Plan” and “Sohu Management Sogou Share Option Arrangement” above. In the first quarter of 2018, Sogou changed the vesting conditions of options for the purchase of 2,181,192 Sogou Class A Ordinary Shares contractually granted under the Sogou 2010 Share Incentive Plan by removing as a condition of vesting Sogou’s achievement of performance targets for the period corresponding to the vesting schedule. Of these options, options for the purchase of 1,601,427 Sogou Class A Ordinary Shares had not been deemed granted, because their performance targets for the current period had not been set, so the removal of the performance targets resulted in these options becoming subject to vesting only upon service-period requirements being met and being deemed granted immediately upon the effectiveness of the changes. For the remaining options for the purchase of 579,765 Sogou Class A Ordinary Shares, which had been deemed granted, the removal of the performance targets constituted a modification. The modification was not considered substantive, because their performance targets had been achieved before the modification. Based on valuation results, no incremental fair value related to these Sogou ordinary shares was recognized in connection with the modification, and the remaining share-based compensation expense for these Sogou ordinary shares continued to be recognized over the remaining vesting period. Sogou Share Repurchase Transaction In January 2017, Sogou repurchased 720,000 of its Pre-IPO Class A Ordinary Shares from the former President and Chief Financial Officer of the Sohu Group for an aggregate price of $7.2 million. Approximately $4.0 million incremental share-based compensation expense associated with the repurchase, which was made pursuant to letter agreements entered into in 2016 between the Sohu Group and the former President and Chief Financial Officer of the Sohu Group in connection with her resignation, which amount is equal to the excess of the repurchase price over the fair value of Sogou Pre-IPO Class A Ordinary Shares as of the repurchase date, related to events occurring in 2016 and was recorded in the Sohu Group’s statements of comprehensive income for the first quarter of 2017. The Group assessed the impact and determined that it was not material to the quarter ended December 31, 2016, the year ended December 31, 2016, or the year ended December 31, 2017. Tencent Share-based Awards Granted to Employees Who Transferred to Sogou with the Soso Search and Search-related Businesses Certain persons who became Sogou employees when Tencent’s Soso search and search-related businesses were transferred to Sogou on September 16, 2013 had been granted restricted share units under Tencent’s share award arrangements prior to the transfer of the businesses. Following the transfer of the businesses, these Tencent restricted share units will continue to vest under the original Tencent share award arrangements provided the transferred employees continue to be employed by Sogou during the requisite service period. After the transfer of the Soso search and search-related businesses to Sogou, Sogou applied the guidance in ASC 505-50 to measure the related compensation expense, which is deemed to have been incurred by Tencent as an investor on Sogou’s behalf, based on the fair value at each reporting date. To determine the then-current fair value of the Tencent restricted share units granted to these employees, the public market price of the underlying shares at each reporting date was applied. For the years ended December 31, 2018, 2017 and 2016, share-based compensation expense of $0.1 million, $0.7 million and $0.8 million, respectively, related to these Tencent restricted share units was recognized in the Group’s consolidated statements of comprehensive income. As of December 31, 2018, there were no unvested Tencent restricted share units held by employees of Sogou and there was no unrecognized compensation expense related to these unvested restricted share units. 3) Changyou.com Limited Share-based Awards Changyou 2008 Share Incentive Plan Changyou’s 2008 Share Incentive Plan (the “Changyou 2008 Share Incentive Plan”) originally provided for the issuance of up to 2,000,000 Changyou ordinary shares, including Changyou ordinary shares issued pursuant to the exercise of share options and upon vesting and settlement of restricted share units. The 2,000,000 reserved Changyou ordinary shares became 20,000,000 Changyou ordinary shares in March 2009 when Changyou effected a ten-for-one share split of its ordinary shares. Most of the awards granted under the Changyou 2008 Share Incentive Plan vest over a period of four years. The maximum term of any share right granted under the Changyou 2008 Share Incentive Plan is ten years from the grant date. The Changyou 2008 Share Incentive Plan expired in August 2018 and is no longer available for granting new share-based awards. All of the restricted Changyou ordinary shares and restricted share units granted under the Changyou 2008 Share Incentive Plan were vested as of December 31, 2017, as the requisite service period for all these awards had been completed. There has been no share-based compensation expense recognized under the Changyou 2008 Share Incentive Plan since then.
Changyou 2014 Share Incentive Plan On June 27, 2014, Changyou reserved 2,000,000 of its Class A ordinary shares under the Changyou.com Limited 2014 Share Incentive Plan (the “Changyou 2014 Share Incentive Plan”) for the purpose of making share incentive awards to certain members of its management and key employees. On November 2, 2014, Changyou’s Board approved an increase in the number of Class A ordinary shares reserved under the Changyou 2014 Share Incentive Plan from 2,000,000 to 6,000,000. The maximum term of any share right granted under the Changyou 2014 Share Incentive Plan is ten years from the grant date. The Changyou 2014 Share Incentive Plan will expire in June 2024. As of December 31, 2018, 3,023,000 shares were available for grant under the Changyou 2014 Share Incentive Plan. i) Summary of Share Option Activity On November 2, 2014, Changyou approved the contractual grant of an aggregate of 2,416,000 Class A restricted share units to certain members of its management and certain other employees. On February 16, 2015, Changyou’s Board of Directors approved the conversion of 2,400,000 of these Class A restricted share units into options for the purchase of Class A ordinary shares at an exercise price of $0.01. On June 1, 2015, Changyou’s Board of Directors approved the contractual grant of options for the purchase of an aggregate of 1,998,000 Class A ordinary shares to certain members of its management and certain other employees at an exercise price of $0.01. On July 28, 2016, Changyou’s Board of Directors approved the contractual grant of options for the purchase of an aggregate of 100,000 Class A ordinary shares to certain member of its management at an exercise price of $0.01. These Changyou share options vest in four equal installments over a period of four years, with each installment vesting upon satisfaction of a service period requirement and the achievement of certain subjective performance targets. These Changyou share options are substantially similar to restricted share units except for the nominal exercise price, which would be zero for restricted share units. Under ASC 718-10-25 and ASC 718-10-55, no grant date can be established until a mutual understanding is reached between the Company and the recipients clarifying the subjective performance requirements. If the service inception date preceded the grant date, compensation expense should be accrued beginning on the service inception date, and re-measured on each subsequent reporting date before the grant date is established, based on the then-current fair value of the awards. To determine the fair value of these Changyou share options, the public market price of the underlying Changyou Class A ordinary shares at each reporting date is used and a binomial valuation model is applied. As of December 31, 2018, 2,718,000 of these Changyou share options had been granted and had become vested on their respective vesting dates, as a mutual understanding of the subjective performance targets had been reached between Changyou and the recipients, the targets had been satisfied, and the service period requirements had been fulfilled. The cumulative share-based compensation expense of $35.4 million for these granted share options was adjusted and fixed based on the aggregate amounts of the fair values of these granted share options at their respective grant dates. A summary of share option activity under the Changyou 2014 Share Incentive Plan as of and for the year ended December 31, 2018 is presented below:
Note (1): The aggregate intrinsic value in the preceding table represents the difference between Changyou’s closing price of $18.28 per ADS, or $9.14 per Class A ordinary share, on December 31, 2018 and the nominal exercise price of the share option.
For the years ended December 31, 2018, 2017 and 2016, total share-based compensation expense recognized for these share options under the Changyou 2014 Share Incentive Plan was negative $6.5 million, $17.4 million and $8.3 million, respectively. For the years ended December 31, 2018, 2017 and 2016, the total fair values of these Changyou share options vested on their respective vesting dates were $5.7 million, $14.8 million and $9.1 million, respectively. For the years ended December 31, 2018, 2017 and 2016, the total intrinsic value of share options exercised was $14.9 million, $10.3 million and $4.3 million, respectively. 4) Sohu Video Share-based Awards On January 4, 2012, Sohu Video adopted the Video 2011 Share Incentive Plan, under which 25,000,000 ordinary shares of Sohu Video are reserved for the purpose of making share incentive awards to management and key employees of Sohu Video and to Sohu management. The maximum term of any share incentive award granted under the Video 2011 Share Incentive Plan is ten years from the grant date. The Video 2011 Share Incentive Plan will expire on January 3, 2022. As of December 31, 2018, grants of options for the purchase of 16,368,200 ordinary shares of Sohu Video had been contractually made and were subject to vesting in four equal installments, with each installment vesting upon a service period requirement being met, as well as Sohu Video’s achievement of performance targets for the corresponding period. For purposes of ASC 718-10-25, as of December 31, 2018, no grant date had occurred, because the broader terms and conditions of the option awards had neither been finalized nor mutually agreed upon with the recipients. As of December 31, 2018, options for the purchase of 4,972,800 Sohu Video ordinary shares were vested. For the years ended December 31, 2018, 2017 and 2016, total share-based compensation expense recognized for vested Sohu Video options under the Video 2011 Share Incentive Plan was negative $0.5 million, negative $0.3 million and $0.8 million, respectively. The fair value as of December 31, 2018 and the Sohu Video options contractually granted to management and key employees of Sohu Video and to Sohu management was estimated on the reporting date using the binomial valuation model, with the following assumptions used:

| NET INCOME /(LOSS) PER SHARE [Abstract] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Net Income /(Loss) per Share | 19. NET INCOME /(LOSS) PER SHARE Basic net income /(loss) per share is computed using the weighted average number of ordinary shares outstanding during the period. Diluted net income /(loss) per share is computed using the weighted average number of ordinary shares and, if dilutive, potential ordinary shares outstanding during the period. Potential ordinary shares comprise shares issuable upon the exercise or settlement of share-based awards using the treasury stock method. The dilutive effect of share-based awards with performance requirements is not considered before the performance targets are actually met. The computation of diluted net income /(loss) per share does not assume conversion, exercise, or contingent issuance of securities that would have an anti-dilutive effect (i.e. an increase in earnings per share amounts or a decrease in loss per share amounts) on net income /(loss) per share. For the years ended December 31, 2016, 2017 and 2018, 232,488, 263,497 and 292,622 ordinary shares, respectively, potentially issuable upon the exercise or settlement of share-based awards using the treasury stock method were anti-dilutive and excluded from the denominator for calculation of diluted net loss per share. Additionally, for purposes of calculating the numerator of diluted net income /(loss) per share, the net income /(loss) attributable to Sohu is adjusted as follows. The adjustment will not be made if there is an anti-dilutive effect. Sogou’s Net Income/(Loss) Attributable to Sohu Before Sogou’s IPO Before Sogou’s IPO, Sogou’s net income /(loss) attributable to Sohu was determined using the percentage that the weighted average number of Sogou shares held by Sohu. represented of the weighted average number of Sogou Pre-IPO Preferred Shares and Sogou Pre-IPO Ordinary Shares outstanding, shares issuable upon the conversion of convertible preferred shares under the if-converted method, and shares issuable upon the exercise or settlement of share-based awards under the treasury stock method, and was not determined by allocating Sogou’s net income /(loss) to Sohu using the methodology for the calculation of net income /(loss) attributable to the Sogou noncontrolling shareholders.
After Sogou’s IPO After Sogou’s IPO, Sogou’s net income /(loss) attributable to Sohu is determined using the percentage that the weighted average number of Sogou shares held by Sohu represents of the weighted average number of Sogou ordinary shares and shares issuable upon the exercise or settlement of share-based awards under the treasury stock method, and not by using the percentage held by Sohu of the total economic interest in Sogou, which is used for the calculation of basic net income per share. In the calculation of Sohu’s diluted net income /(loss) per share, assuming a dilutive effect, the percentage of Sohu’s shareholding in Sogou was calculated by treating convertible preferred shares issued by Sogou as having been converted at the beginning of the period and unvested Sogou share options with the performance targets achieved as well as vested but unexercised Sogou share options as having been exercised during the period. The dilutive effect of share-based awards with a performance requirement was not considered before the performance targets were actually met. The effect of this calculation is presented as “incremental dilution from Sogou” in the table below. Assuming an anti-dilutive effect, all of these Sogou shares and share options are excluded from the calculation of Sohu’s diluted income /(loss) per share. As a result, Sogou’s net income /(loss) attributable to Sohu on a diluted basis equals the number used for the calculation of Sohu’s basic net income /(loss) per share. For the year ended December 31, 2018, all of the Sogou share options had a dilutive effect, and therefore were included in the calculation of Sohu.com Limited’s diluted net income /(loss) per share. This impact is presented as “incremental dilution from Sogou” in the table below. Changyou’s Net Income/(Loss) Attributable to Sohu Changyou’s net income /(loss) attributable to Sohu is determined using the percentage that the weighted average number of Changyou shares held by Sohu represents of the weighted average number of Changyou ordinary shares and shares issuable upon the exercise or settlement of share-based awards under the treasury stock method, and not by using the percentage held by Sohu of the total economic interest in Changyou, which is used for the calculation of basic net income per share. In the calculation of Sohu’s diluted net income /(loss) per share, assuming a dilutive effect, all of Changyou’s existing unvested restricted share units and share options, and vested restricted share units and share options that have not yet been settled, are treated as vested and settled by Changyou under the treasury stock method, causing the percentage of the weighted average number of shares held by Sohu in Changyou to decrease. As a result, Changyou’s net income /(loss) attributable to Sohu on a diluted basis decreased accordingly. The effect of this calculation is presented as “incremental dilution from Changyou” in the table below. Assuming an anti-dilutive effect, all of these Changyou restricted share units and share options are excluded from the calculation of Sohu’s diluted net income /(loss) per share. As a result, Changyou’s net income /(loss) attributable to Sohu on a diluted basis equals the number used for the calculation of Sohu’s basic net income /(loss) per share. For the year ended December 31, 2018, all of these Changyou restricted share units and share options had an dilutive effect, and therefore were included in the calculation of Sohu.com Limited’s diluted net income /(loss) per share. This impact is presented as “incremental dilution from Changyou” in the table below. The following table presents the calculation of the Sohu Group’s basic and diluted net loss per share (in thousands, except per share data).

| PROFIT APPROPRIATION [Abstract] | |
| Profit Appropriation | 21. PROFIT APPROPRIATION The Sohu Group’s China-based subsidiaries and VIEs are required to make appropriations to certain non-distributable reserve funds. In accordance with the China Foreign Investment Enterprises laws, those of the Group’s China-based subsidiaries that are considered under PRC law to be WFOEs are required to make appropriations from their after-tax profit as determined under generally accepted accounting principles in the PRC (the “after-tax-profit under PRC GAAP”) to non-distributable reserve funds, including (i) a general reserve fund, (ii) an enterprise expansion fund, and (iii) a staff bonus and welfare fund. Each year, at least 10% of the after-tax-profit under PRC GAAP is required to be set aside as general reserve fund until such appropriations for the fund equal 50% of the registered capital of the applicable entity. The appropriation for the other two reserve funds is at the Group’s discretion as determined by the Board of Directors of each entity. Pursuant to the China Company Laws, those of the Group’s China-based subsidiaries that are considered under PRC law to be domestically funded enterprises, as well as the Group’s VIEs, are required to make appropriations from their after-tax-profit under PRC GAAP to non-distributable reserve funds, including a statutory surplus fund and a discretionary surplus fund. Each year, at least 10% of the after-tax-profit under PRC GAAP is required to be set aside as statutory surplus fund until such appropriations for the fund equal 50% of the registered capital of the applicable entity. The appropriation for the discretionary surplus fund is at the Company’s discretion as determined by the Board of Directors of each entity. Upon certain regulatory approvals and subject to certain limitations, the general reserve fund and the statutory surplus fund can be used to offset prior year losses, if any, and can be converted into paid-in capital of the applicable entity. For the years ended December 31, 2018, 2017 and 2016, the total amount of profits contributed to these funds by the Group was $7.3 million, $12.0 million and $4.3 million, respectively. As of December 31, 2018 and 2017, the total amount of profits contributed to these funds by the Group was $70.3 million and $63.0 million, respectively. As a result of these and other restrictions under PRC laws and regulations, the Group’s China-based subsidiaries and VIEs are restricted in their ability to transfer a portion of their net assets in the form of non-distributable reserve funds to the Company in the form of dividends, loans or advances. Even though the Company currently does not require any such dividends, loans or advances from its China-based subsidiaries and VIEs for working capital and other funding purposes, the Company may in the future require additional cash resources from its China-based subsidiaries and VIEs due to changes in business conditions, to fund future acquisitions and development, or to declare and pay dividends to or make distributions to its shareholders. |

| CONCENTRATION RISKS [Abstract] | |
| Concentration Risks | 22. CONCENTRATION RISKS Because its operations are substantially conducted in the PRC, the Sohu Group is subject to PRC-related political, economic and legal risks. Besides these risks, the Sohu Group may also have the following concentration risks. Operation Risk For the years ended December 31, 2018, 2017 and 2016, there were no revenues from customers that individually represent greater than 10% of the total online advertising revenues.
For the year ended December 31, 2018, revenues from TLBB were $200.9 million, accounting for approximately 52% of Changyou’s online game revenues, approximately 41% of Changyou’s total revenues and approximately 11% of the Sohu Group’s total revenues. For the year ended December 31, 2018, revenues from Legacy TLBB Mobile were $101.6 million, accounting for approximately 26% of Changyou’s online game revenues, approximately 21% of Changyou’s total revenues, and approximately 5% of the Sohu Group’s total revenues. Financial instruments that potentially subject the Sohu Group to concentration risks consist primarily of cash and cash equivalents and short-term investments. Cash and cash equivalents in Sohu Group are mainly denominated in RMB and in U.S. dollars. Short-term investments are denominated in RMB. The Group may experience economic losses and negative impacts on earnings and equity as a result of fluctuations in the exchange rate between the U.S. dollar and the RMB. Moreover, the Chinese government imposes controls on the convertibility of RMB into foreign currencies and, in certain cases, the remittance of currency out of the PRC. The Group may experience difficulties in completing the administrative procedures necessary to obtain and remit foreign currency. Credit Risk As of December 31, 2018, approximately 60% of the Sohu Group’s cash and cash equivalents and short-term investments were held in 17 financial institutions in Mainland China. The remaining cash and cash equivalents and short-term investments were held primarily in financial institutions in Hong Kong and Macao. As of December 31, 2017, approximately 58% of the Sohu Group’s cash and cash equivalents and short-term investments were held in 19 financial institutions in Mainland China. The remaining cash and cash equivalents and short-term investments were held primarily in financial institutions in Hong Kong and Macao. The Sohu Group holds its cash and bank deposits at Chinese financial institutions that are among the largest and most respected in the PRC and at international financial institutions with high ratings from internationally-recognized rating agencies. The management chooses these institutions because of their reputations and track records for stability, and their known large cash reserves, and management periodically reviews these institutions’ reputations, track records, and reported reserves. Management expects that any additional institutions that the Sohu Group uses for its cash and bank deposits will be chosen with similar criteria for soundness. As a further means of managing its credit risk, the Sohu Group holds its cash and bank deposits in a number of different financial institutions. As of December 31, 2018 and 2017, the Sohu Group held its cash and bank deposits in different financial institutions and held no more than approximately 35% and 30%, respectively, of its total cash at any single institution. Under PRC law, it is generally required that a commercial bank in the PRC that holds third party cash deposits protect the depositors’ rights over and interests in their deposited money; PRC banks are subject to a series of risk control regulatory standards; and PRC bank regulatory authorities are empowered to take over the operation and management of any PRC bank that faces a material credit crisis. For the credit risk related to accounts receivable, the Sohu Group performs ongoing credit evaluations of its customers and, if necessary, maintains reserves for potential credit losses. Historically, such losses have been within management’s expectations. |

| RESTRICTED NET ASSETS [Abstract] | |
| Restricted Net Assets | 23. RESTRICTED NET ASSETS Relevant PRC law and regulations permit payment of dividends by PRC-based operating entities only out of their retained earnings, if any, as determined in accordance with PRC accounting standards and regulations. In addition, a PRC-based operating entity is required to annually appropriate 10% of net after-tax income to the statutory surplus reserve fund (see Note 21) prior to payment of any dividends, unless such reserve funds have reached 50% of the entity’s registered capital. As a result of these and other restrictions under PRC law and regulations, PRC-based operating entities are restricted in their ability to transfer a portion of their net assets to the Company either in the form of dividends, loans or advances. The Company may in the future require additional cash resources from PRC-based operating entities due to changes in business conditions, to fund future acquisitions and development, or to declare and pay dividends to or distribution to its shareholders. As of December 31, 2018, the Group had restricted net assets in the amount of $588.4 million. |

| Use of Estimates | Use of Estimates The preparation of these financial statements requires the Sohu Group to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues, costs and expenses, and related disclosures. On an on-going basis, the Group evaluates its estimates based on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. Identified below are the accounting policies that reflect the Group’s most significant estimates and judgments, and those that the Group believes are the most critical to fully understanding and evaluating its consolidated financial statements. |

| Basis of Consolidation and Recognition of Noncontrolling Interest | Basis of Consolidation and Recognition of Noncontrolling Interest The Sohu Group’s consolidated financial statements include the accounts of the Company and its subsidiaries and consolidated VIEs. All intra-Group transactions are eliminated. VIE Consolidation The Sohu Group’s VIEs are wholly or partially owned by certain employees of the Group as nominee shareholders. For consolidated VIEs, management made evaluations of the relationships between the Sohu Group and the VIEs and the economic benefit flow of contractual arrangements with the VIEs. In connection with such evaluation, management also took into account the fact that, as a result of such contractual arrangements, the Group controls the shareholders’ voting interests in these VIEs. As a result of such evaluation, management concluded that the Sohu Group is the primary beneficiary of its consolidated VIEs. Noncontrolling Interest Recognition Noncontrolling interests are recognized to reflect the portion of the equity of subsidiaries and VIEs which is not attributable, directly or indirectly, to the controlling shareholders. Currently, the noncontrolling interests in the Sohu Group’s consolidated financial statements primarily consist of noncontrolling interests for Sogou and Changyou. Noncontrolling Interest for Sogou Prior to the completion of Sogou’s IPO in November 2017, the Company controlled the election of a majority of the Board of Directors of Sogou pursuant to a shareholders’ agreement that expired upon completion of the IPO. Following the completion of Sogou’s IPO, pursuant to the Voting Agreement and Sogou’s Third Amended and Restated Articles of Association, the Company still has the right to appoint a majority of Sogou’s Board of Directors. As Sogou’s controlling shareholder, the Company consolidates Sogou in its consolidated financial statements, and recognizes noncontrolling interest reflecting economic interests in Sogou held by shareholders other than it (the “Sogou noncontrolling shareholders”). Sogou’s net income /(loss) attributable to the Sogou noncontrolling shareholders is recorded as noncontrolling interest in its consolidated statements of comprehensive income. Noncontrolling Interest Recognition before Sogou’s IPO Based on the principles of allocation of Sogou’s profit and loss set forth below, Sogou’s cumulative results of operations attributable to the Sogou noncontrolling shareholders, along with changes in shareholders’ equity/(deficit) and adjustments for share-based compensation expense in relation to those share-based awards that were unvested and vested but not yet settled and the Sogou noncontrolling shareholders’ investments in Sogou Series A Preferred Shares outstanding before Sogou’s IPO (“Sogou Pre-IPO Series A Preferred Shares”) and Sogou Series B Preferred Shares outstanding before Sogou’s IPO (“Sogou Pre-IPO Series B Preferred Shares”) (together, the “Sogou Pre-IPO Preferred Shares”) and Sogou ordinary shares outstanding before Sogou’s IPO (“Sogou Pre-IPO Class A Ordinary Shares” and “Sogou Pre-IPO Class B Ordinary Shares, as applicable) were accounted for as a noncontrolling interest classified as permanent equity in the Sohu Group’s consolidated balance sheets, as Sohu Group had the power to reject a redemption requested by the noncontrolling shareholders. These treatments were based on the terms governing investment, and on the terms of the classes of Sogou shares held, by the noncontrolling shareholders in Sogou before Sogou’s IPO. Principles of Allocation of Sogou’s Profit and Loss - By virtue of the terms of the Sogou Pre-IPO Preferred Shares, Pre-IPO Class A Ordinary Shares, and Pre-IPO Class B Ordinary Shares, Sogou’s losses were allocated in the following order before Sogou’s IPO: (i) net losses were allocated to holders of the Sogou Pre-IPO Class A Ordinary Shares and the holder of the Sogou Pre-IPO Class B Ordinary Shares until their basis in Sogou decreased to zero; (ii) additional net losses were allocated to holders of the Sogou Pre-IPO Series A Preferred Shares until their basis in Sogou decreased to zero; (iii) additional net losses were allocated to the holder of the Sogou Pre-IPO Series B Preferred Shares until its basis in Sogou decreased to zero; and (iv) further net losses were allocated between Sohu and noncontrolling shareholders based on their shareholding percentage in Sogou. Net income from Sogou was allocated in the following order before Sogou’s IPO: (i) net income was allocated between Sohu and noncontrolling shareholders based on their shareholding percentage in Sogou until their basis in Sogou increased to zero; (ii) additional net income was allocated to the holder of the Sogou Pre-IPO Series B Preferred Shares to bring its basis back; (iii) additional net income was allocated to holders of the Sogou Pre-IPO Series A Preferred Shares to bring their basis back; (iv) further net income was allocated to holders of the Sogou Pre-IPO Class A Ordinary Shares and the holder of the Sogou Pre-IPO Class B Ordinary Shares to bring their basis back; and (v) further net income was allocated between Sohu and noncontrolling shareholders based on their shareholding percentage in Sogou. Noncontrolling Interest Recognition after Sogou’s IPO Sogou’s cumulative results of operations attributable to the Sogou noncontrolling shareholders, based on their share of the economic interest in Sogou, along with changes in shareholders’ equity and adjustment for share-based compensation expense in relation to share-based awards that are unvested and vested but not yet settled and adjustment for changes in the Sohu Group’s ownership percentage in Sogou, are recorded as noncontrolling interest in the Sohu Group’s consolidated balance sheets. Noncontrolling Interest for Changyou As of the date of this report, Sohu holds approximately 67% of the combined total of Changyou’s outstanding ordinary shares, and controls approximately 95% of the total voting power in Changyou.
As Changyou’s controlling shareholder, Sohu consolidates Changyou in its consolidated financial statements, and recognizes noncontrolling interest reflecting the economic interest in Changyou held by shareholders other than the Company (the “Changyou noncontrolling shareholders”). Changyou’s net income /(loss) attributable to the Changyou noncontrolling shareholders is recorded as noncontrolling interest in the Sohu Group’s consolidated statements of comprehensive income, based on the noncontrolling shareholders’ share of the economic interest in Changyou. Changyou’s cumulative results of operations attributable to the Changyou noncontrolling shareholders, along with changes in shareholders’ equity, adjustment for share-based compensation expense in relation to those share-based awards which are unvested and vested but not yet settled and adjustment for changes in the Company’s ownership in Changyou, are recorded as noncontrolling interest in the Sohu Group’s consolidated balance sheets. Segment Reporting The Sohu Group’s segments are business units that offer different services and are reviewed separately by the chief operating decision maker (the “CODM”), or the decision making group, in deciding how to allocate resources and in assessing performance. The Group’s CODM is the Company’s Chief Executive Officer. |

| Revenue Recognition | Revenue Recognition Impact of Adoption of ASC 606 On January 1, 2018, the Sohu Group adopted ASC 606, applying the modified retrospective method to contracts that were not completed as of January 1, 2018. The adoption of ASC 606 did not have a material impact on the Company’s accumulated deficit as of January 1, 2018. Results for reporting periods beginning on or after January 1, 2018 are presented under ASC 606, while prior-period amounts are not adjusted and continue to be reported in accordance with the Group’s historic accounting under ASC 605. Under ASC 605, advertising-for-advertising barter transactions for which the fair value of the advertising services was not determinable were recorded at the carrying amount of the advertising surrendered, since the Group did not settle such barter transactions with the counterparties in cash. As ASC 605 has been superseded by ASC 606 on this subject, advertising-for-advertising barter transactions are to be recorded at the fair value of the advertising received by reference to the fair value of advertising services provided to other customers. The impact for the year of 2018 was an increase of approximately $25.6 million in revenues, with corresponding increases in cost of revenues and sales and marketing expenses, most of which were generated from Sogou for services provided to and received from Tencent. To a lesser extent, there is a potential impact on the Group’s accounting for exchanges of brand advertising placements with other platforms by Sohu. Revenues are recognized in the same amount as the corresponding costs and expenses. Therefore, there was no net profit and loss impact to the Group for the year of 2018. The following table illustrates the effect of the adoption of ASC 606 by presenting a comparison of selected line items from the Group’s consolidated statement of comprehensive income for the year ended December 31, 2018, as actually reported and as they would have been reported under ASC 605 without the adoption of ASC 606 (in thousands, except per share data):
The adoption of ASC 606 did not change the Group’s consolidated balance sheet, consolidated statement of cash flows, or consolidated statement of changes in equity as of, or for the year ended, December 31, 2018. Revenues are recognized when control of the promised goods or services is transferred to the Group’s customers, in an amount that reflects the consideration the Group expects to be entitled to in exchange for those goods or services. The recognition of revenues involves certain management judgments, including estimated lives of virtual items purchased by game players, the estimation of the fair value of an advertising-for-advertising barter transaction, allocation of upfront license fees for licensed-out games between license and post-sale services, and volume sales rebates. The Group does not believe that significant management judgements are involved in revenue recognition, but the amount and timing of the Group’s revenues could be different for any period if management made different judgments or utilized different estimates. The following table presents the Group’s revenues disaggregated by products and services:
As noted above, in accordance with the modified retrospective method upon adoption of ASC 606, prior-period amounts were not adjusted. Online Advertising Revenues Online advertising revenues include revenues from brand advertising services as well as search and search-related advertising services. Certain customers may receive sales rebates, which are accounted for as variable consideration. The Group estimates annual the expected revenue volume from each agent with reference to its historical results. Sales rebates will reduce revenues recognized. The Group recognizes revenue for the amount of fees it receives from its advertisers, after deducting sales rebates and net of value-added tax (“VAT”). The Group believes that there will not be significant changes to its estimates of variable consideration. Brand Advertising Revenues Revenue Recognition of Multiple Performance Obligations The Group’s contracts with customers may include multiple performance obligations. For such arrangements, the Group allocates revenues to each performance obligation based on its relative standalone selling price. The Group generally determines the standalone selling price of each distinct performance obligation based on the prices charged to customers when sold on a standalone basis. Where a standalone selling price is not directly observable, the Group generally estimates the selling price based on the prices at which performance obligations of a similar nature and geography are charged to customers. Most of such contracts have all performance obligations completed within the same quarter.
Pricing Model Through PCs and mobile devices, the Group provides advertisement placements to its advertisers on different Internet platforms and in different formats, which include banners, links, logos, buttons, full screen, pre-roll, mid-roll, post-roll video screens, pause video screens, loading page ads, news feed ads and in-feed video infomercial ads. Currently the Group has three main types of pricing models, consisting of the Fixed Price model, the Cost Per Impression (“CPM”) model and the Cost Per click (“CPC”) model.
Under the Fixed Price model, a contract is signed to establish a fixed price for the advertising services to be provided. Given that the advertisers benefit from displayed advertisements evenly over the period the advertisements are displayed, the Group recognizes revenue on a straight-line basis over the period of display, provided all revenue recognition criteria have been met.
Under the CPM model, the unit price for each qualifying display is fixed and stated in the contract with the advertiser. A qualifying display is defined as the appearance of an advertisement, where the advertisement meets criteria specified in the contract. Given that the fees are priced consistently throughout the contract and the unit prices are fixed in accordance with the Group’s pricing practices for similar advertisers, the Group recognizes revenue based on the fixed unit prices and the number of qualifying displays upon their occurrence, provided all revenue recognition criteria have been met.
Under the CPC model, there is no fixed price for advertising services stated in the contract with the advertiser and the unit price for each click is auction-based. The Group charges advertisers on a per-click basis, when the users click on the advertisements. Given that the fees are priced consistently throughout the contract and the unit prices are fixed in accordance with the Group’s pricing practices for similar advertisers, the Group recognizes revenue based on qualifying clicks and unit price upon the occurrence of the clicks, provided all revenue recognition criteria have been met. Search and Search-related Advertising Revenues Search and search-related services consist primarily of search and search-related advertising services offered by Sogou. Pay-for-click Services Pay for click services enable advertisers’ promotional links to be displayed on Sogou search result pages and other Internet properties and third parties’ Internet properties where the links are relevant to the subject and content of searches and such properties. For pay for click services, Sogou introduces Internet users to its advertisers through auction-based systems and charges advertisers on a per-click basis when the users click on the displayed links. The performance obligation of pay-for-click services is satisfied at the point in time when the user clicks on the displayed links, and revenue for pay-for-click services is recognized on a per-click basis. Other Online Advertising Services Other online advertising services mainly consist of displaying advertisers’ promotional links on Sogou’s Internet properties. For time-based advertising services, the Sogou’s performance obligation is satisfied over time when the advertising links are displayed over the contract periods, and revenue is normally recognized on a straight-line basis over the contracted display period. For performance-based advertising services, for example, advertisers are charged based on the times that users download from the displayed links, Sogou’s performance obligation is satisfied at the point in time when the promised performance is completed, and the revenue is recognized upon the completion of the promised performance. Sogou’s online advertising services expand distribution of advertisers’ promotional links and advertisements by leveraging traffic on third parties’ Internet properties, including Web content, software, and mobile applications. Sogou is the principal in such arrangement because its promise to advertisers is to provide the advertising services itself rather than to arrange for the advertising services to be provided by third parties on their Internet properties. Payments made to operators of third-party Internet properties are included in traffic acquisition costs.
Online Game Revenues Changyou’s online game revenues are generated primarily from its self-operated and licensed-out PC games and mobile games. All of Changyou’s games are operated under the item-based revenue model, where the basic game play functions are free of charge and players are charged for purchases of in-game virtual items, including those with a predetermined expiration time and perpetual virtual items. Changyou is the principal of its self-operated games. Changyou hosts the games on its own servers and is responsible for the sale and marketing of the games as well as customer service. Accordingly, revenues are recorded gross of revenue sharing-payments to third-party developers and/or mobile APP stores, but net of VAT and discounts to game card distributors where applicable. Changyou obtains revenues from the sale of in-game virtual items. Revenues are recognized as the virtual items are consumed or over the estimated lives of the virtual items, which are estimated by considering the average period that paying players typically play Changyou’s games and other player behavior patterns derived from operating data. If different assumptions were used in deriving the estimated lives of the virtual items, the timing of the recording of the revenues could be impacted. PC Games Proceeds from Changyou’s self-operated PC games are collected from players and third-party game card distributors through sales of Changyou’s game points on its online payment platform and prepaid game cards. Changyou’s self-operated PC games are either developed in house or licensed from third-party developers. For licensed PC games, Changyou remits a pre-agreed percentage of the proceeds to the third-party developers pursuant to revenue-sharing agreements, and keeps the balance. Such revenue-sharing amounts paid to third-party developers are recorded in Changyou’s cost of revenues. Mobile Games Self-operated Mobile Games For self-operated mobile games, Changyou sells game points to its game players via third-party mobile APP stores. The mobile APP stores in turn pay Changyou proceeds after deducting their share of pre-agreed revenue-sharing amounts. Changyou’s self-operated mobile games are either developed in house or licensed from or jointly developed with third-party developers. For licensed and jointly-developed mobile games, Changyou remits a pre-agreed percentage of the proceeds to the third-party developers pursuant to revenue-sharing agreements, and keeps the balance. Such revenue-sharing amounts paid to mobile application stores and third-party developers are recorded in Changyou’s cost of revenues. Licensed Out Mobile Games Changyou also authorizes third parties to operate its mobile games. Licensed out games mainly include mobile games developed in house, such as Changyou’s mobile game Legacy TLBB Mobile, and mobile games jointly developed with third-party developers. Changyou receives monthly revenue-based royalty payments from the third-party licensee operators. Changyou receives additional up-front license fees from certain third-party licensee operators who are entitled to an exclusive right to operate Changyou’s games in specified geographic areas. Since Changyou is obligated to provide post-sale services (“PCS”), the initial license fees are allocated between the license and PCS based on relative standalone selling prices. The amount allocated to the license is recognized as revenue upon the commencement of the license period, given that Changyou’s intellectual property rights subject to the license are considered to be functional and the licensee has the right to use such intellectual property rights as they exist at the point when the license is granted, and the amount allocated to PCS is recognized as revenue ratably over the license period. Monthly revenue-based royalty payments are recognized when the relevant services are delivered, provided that collectability is reasonably assured. Changyou views the third-party licensee operators as Changyou’s customers and recognizes revenues on a net basis, as Changyou does not have the primary responsibility for fulfillment and acceptability of the game services. Changyou remits to the third-party developers a pre-agreed percentage of revenues and keeps the balance pursuant to revenue-sharing agreements. Such revenue-sharing amounts paid to third-party developers are included in Changyou’s cost of revenues or product development expenses. Other Revenues Sohu Other revenues attributable to Sohu consist primarily of revenues from paid subscription services, interactive broadcasting services, and content provided through the platforms of the three main telecommunications operators in China.
Sogou Other revenues attributable to Sogou are IVAS revenues, which are mainly from the operation of Web games and mobile games developed by third parties and the provision of online reading services, and revenues from other products and services, including smart hardware. Changyou Other revenues attributable to Changyou are primarily from its cinema advertising business and from IVAS. In its cinema advertising business, Changyou provides clients advertising placements in slots that are shown in theaters before the screening of movies. The rights to place advertisements in such advertising slots are granted to Changyou, which takes inventory risk under the contracts Changyou signs with different theaters. Changyou charges its advertising clients fees either on a per advertising-slot basis or a fixed amount for an agreed-upon number of slots during a specified contract period. When delivery of the advertising service is confirmed by the customers by their signing a form, revenues from cinema advertising are recognized based on a percentage of the advertising slots actually delivered or on a straight-line basis over the contract period. As Changyou is considered to be the principal in the arrangements with the theaters, the fees paid to the theaters are recognized as cost of revenues. Changyou provides IVAS primarily through software applications for PCs and mobile devices offered by RaidCall. Prior to March 2018, IVAS revenues also included revenues generated from the Dolphin Browser operated by MoboTap. Revenues from IVAS are recognized during the period the services are rendered or items are consumed under the gross method, as Changyou is the principal obligor for provision of the services. Contract Balances Timing of revenue recognition may differ from the timing of invoicing to customers. Accounts receivable represent amounts invoiced and revenue recognized prior to invoicing, when the Group has satisfied its performance obligations and has the unconditional right to payment. The allowance for doubtful accounts and authorized credits is estimated based upon the Group’s assessment of various factors, including historical experience, the age of the accounts receivable balances, current economic conditions and other factors that may affect the Group’s customers’ ability to pay. Contract assets as of December 31, 2018 were not material. The allowance for doubtful accounts and authorized credits was $16.9 million and $5.7 million, respectively, as of December 31, 2018 and December 31, 2017. Receipts in advance and deferred revenue relate to unsatisfied performance obligations at the end of the period and primarily consist of fees received from game players in the online game business and from advertisers in the search and search-related advertising business. Due to the generally short-term duration of the contracts, the majority of the performance obligations are satisfied in the following reporting period. The amount of revenue recognized that was included in the receipts in advance and deferred revenue balance at the beginning of the period was $111.7 million for the year ended December 31, 2018. There was no significant change in the contract assets and contract liability balances during 2018. Revenue recognized in 2018 from performance obligations related to prior years was not material. Practical Expedients The Group has used the following practical expedients as allowed under ASC 606: (i) The transaction price allocated to performance obligations that are unsatisfied or partially unsatisfied has not been disclosed, as substantially all of the Group’s contracts have a duration of one year or less. (ii) Payment terms and conditions vary by contract type, although terms generally include a requirement of prepayment or payment within one year or less. In instances where the timing of revenue recognition differs from the timing of invoicing, the Group has determined that its contracts generally do not include a significant financing component. (iii) The Group applied the portfolio approach in determining the commencement date of consumption and the estimated lives of virtual items for the recognition of games revenue, given that the effect of applying a portfolio approach to a group game players’ behaviors would not differ materially from considering each one of them individually. (iv) The Group generally expenses sales commissions when incurred because the amortization period would be one year or less. These costs are recorded within sales and marketing expenses. |

| Cost of Revenues |
Cost of Revenues Cost of Online Advertising Revenues Cost of online advertising revenues includes cost of revenues from brand advertising services as well as cost of revenues from search and search-related services. Cost of Brand Advertising Revenues Cost of brand advertising revenues mainly consists of content and license costs, salary and benefits expenses, and bandwidth leasing costs. For self-developed video content, production costs incurred in excess of the amount of revenue contracted for are expensed as incurred. Cost of Search and Search-related Advertising Revenues Cost of search and search-related advertising revenues mainly consists of traffic acquisition costs, bandwidth leasing costs, depreciation expenses, salary and benefits expenses, and share-based compensation expense. Traffic acquisition costs consist primarily of payments to third parties that direct search queries of the users to Internet properties of Sogou or distribute Sogou advertisers’ promotional links through such third parties’ Internet properties. The traffic acquisitions costs for such arrangements consist primarily of fees that Sogou pays to the third parties based on an agreed-upon unit price and revenue-sharing payments that Sogou makes to such third parties based on an agreed-upon percentage of revenues generated from users’ clicks. Cost of Online Game Revenues Cost of online game revenues mainly consists of revenue-sharing payments, salary and benefits expenses, bandwidth leasing costs, content and license costs, tax surcharges, depreciation and amortization expenses, and other direct costs.

| Share-based Compensation Expense | Share-based Compensation Expense Sohu (excluding Sohu Video), Sogou, Changyou, and Sohu Video have incentive plans for the granting of share-based awards, including share options and restricted share units, to members of the boards of directors, management and other key employees. For share-based awards for which a grant date has occurred, share-based compensation expense is recognized as costs and expenses in the consolidated statements of comprehensive income based on the fair value of the related share-based awards on their grant dates. For share-based awards for which the service inception date precedes the grant date, share-based compensation expense is recognized as costs and expenses in the consolidated statements of comprehensive income beginning on the service inception date and is re-measured on each subsequent reporting date before the grant date, based on the estimated fair value of the related share-based awards. Share-based compensation expense is charged to the shareholders’ equity or noncontrolling interest section in the consolidated balance sheets. The assumptions used in share-based compensation expense recognition represent management’s best estimates, but these estimates involve inherent uncertainties and the application of management judgment. If factors change or different assumptions are used, the Group’s share-based compensation expense could be materially different for any period. Moreover, the estimates of fair value are not intended to predict actual future events or the value that ultimately will be realized by employees who receive equity awards. Sohu (excluding Sohu Video), Sogou, and Changyou Share-based Awards Sohu (excluding Sohu Video) Share-based Awards In determining the fair values of share options granted by Sohu (excluding Sohu Video) as share-based awards, the public market price of the underlying shares at each reporting date was used, and a binomial valuation model was applied. In determining the fair value of restricted share units granted, the public market price of the underlying shares on the grant dates was applied. Upon the dissolution of Sohu.com Inc. on May 31, 2018, Sohu.com Limited assumed all then existing obligations of Sohu.com Inc. with respect to equity incentive awards that had been granted under Sohu.com Inc.’s Amended and Restated 2010 Stock Incentive Plan (the “Sohu 2010 Stock Incentive Plan”) and remained outstanding, and such awards were converted into the right to receive upon exercise or settlement Sohu.com Limited’s ordinary shares under the Sohu.com Limited 2018 Share Incentive Plan (the “Sohu 2018 Share Incentive Plan”) rather than shares of the common stock of Sohu.com Inc., subject to the other terms of such outstanding awards. Options for the purchase of Sohu.com Limited’s ordinary shares, including options converted from those contractually granted under the Sohu 2010 Stock Incentive Plan, are subject to vesting in four equal installments over a period of four years, with each installment vesting upon satisfaction of a service period requirement and certain subjective performance targets. Under ASC 718-10-25, no grant date can be established until a mutual understanding is reached between Sohu and the recipients clarifying the subjective performance requirements. In accordance with ASC 718-10-55, as the service inception date preceded the grant date, compensation expense was accrued beginning on the service inception date and will be re-measured on each subsequent reporting date before the grant date is established, based on the then-current fair value of the awards. The estimate of the awards’ fair values will be fixed in the period in which the grant date occurs, and cumulative compensation expense will be adjusted based on the fair value at the grant date. Sogou Share-based Awards In determining the fair value of share options granted by Sogou as share-based awards, a binomial valuation model was applied. The determination of the fair value is affected by the fair value of the ordinary shares as well as assumptions regarding a number of complex and subjective variables, including risk-free interest rates, exercise multiples, expected forfeiture rates, expected share price volatility rates, and expected dividends. Before the completion of Sogou’s IPO, the fair values of the ordinary shares were assessed using the income approach/discounted cash flow method or based on the mid-point of the estimated IPO price range, in each case with a discount for lack of marketability, given that the shares underlying the awards were not publicly traded at the time of grant. After the completion of Sogou’s IPO, the fair values of the ordinary shares were determined based on the trading price of Sogou’ ADSs in the public market. Certain persons who became Sogou employees when Tencent’s Soso search-related businesses were transferred to Sogou in 2013 had been granted restricted share units under Tencent’s share award arrangements prior to the transfer of the businesses to Sogou. These Tencent restricted share units will continue to vest under the original Tencent share award arrangements provided the transferred employees continue to be employed by Sogou during the requisite service period. After the transfer of the Soso search-related businesses to Sogou, Sogou applied the guidance in ASC 505-50 to measure the related compensation expense based on the then-current fair value at each reporting date, as the expense is deemed to have been incurred by Tencent as an investor on Sogou’s behalf. To determine the then-current fair value of the Tencent restricted share units granted to these employees, the public market price of the underlying shares at each reporting date was applied. Because Sogou is not required to reimburse Tencent for such share-based compensation expense, the related amount was recorded by Sogou as a capital contribution from Tencent. Changyou Share-based Awards In determining the fair value of ordinary shares and restricted share units granted by Changyou as share-based awards in 2008, the income approach /discounted cash flow method with a discount for lack of marketability was applied, given that the shares underlying the awards were not publicly traded at the time of grant. Changyou’s 2008 Share Incentive Plan expired in August 2018 and is no longer available for granting new share-based awards. In determining the fair value of restricted share units granted after Changyou’s IPO, the public market price of the underlying shares on the grant dates was applied. Options for the purchase of Changyou Class A ordinary shares contractually granted under the Changyou 2014 Share Incentive Plan are subject to vesting in four equal installments over a period of four years, with each installment vesting upon satisfaction of a service period requirement and certain subjective performance targets. Under ASC 718-10-25, no grant date can be established until a mutual understanding is reached between Changyou and the recipients clarifying the subjective performance requirements. In accordance with ASC 718-10-55, as the service inception date preceded the grant date, compensation expense was accrued beginning on the service inception date and will be re-measured on each subsequent reporting date before the grant date is established, based on the then-current fair value of the awards. The estimates of the awards’ fair values will be fixed in the period in which the grant date occurs, and cumulative compensation expense will be adjusted based on the fair values at the grant date. In determining the fair values of Changyou share options granted, the public market price of the underlying shares at each reporting date was used, and a binomial valuation model was applied. Compensation Expense Recognition For options and restricted share units granted with respect to Sohu (excluding Sohu Video) shares and Changyou shares, compensation expense is recognized on an accelerated basis upon the requisite service period and certain subjective performance targets being met. For share options granted with respect to Sogou shares, compensation expense is recognized over the estimated period during which the service period requirement and performance target will be met, which is usually within one year, or, after the performance target of Sogou’s completion of an IPO was met upon the completion of Sogou’s IPO on November 13, 2017, on an accelerated basis over the requisite service period, or, for options with only service period requirement, on an accelerated basis over the requisite service period. For Tencent restricted share units that Tencent had granted to employees who transferred to Sogou with the Soso search and search-related businesses, compensation expense is recognized by Sogou on an accelerated basis over the requisite service period, and the fair value of the share-based compensation is re-measured at each reporting date until the service has been provided. The number of share-based awards for which the service is not expected to be rendered over the requisite period is estimated, and no compensation expense is recorded for the number of awards so estimated. Sohu Video Share-based Awards On January 4, 2012, Sohu Video, the holding entity of Sohu’s video division, adopted a 2011 Share Incentive Plan (the “Video 2011 Share Incentive Plan”) which provides for the issuance of up to 25,000,000 ordinary shares of Sohu Video (representing approximately 10% of the outstanding Sohu Video shares on a fully-diluted basis) to management and key employees of the video division and to Sohu management. As of December 31, 2018, grants of options for the purchase of 16,368,200 ordinary shares of Sohu Video had been contractually made, of which options for the purchase of 4,972,800 ordinary shares were vested. For purposes of ASC 718-10-25, as of December 31, 2018, no grant date had occurred, because the broader terms and conditions of the option awards had neither been finalized nor mutually agreed upon with the recipients. Therefore the fair value of the awards was not determinable and could not be accounted for. In accordance with ASC 718-10-55, the Group’s management determined that the service inception date with respect to vested option awards for the purchase of 4,972,800 shares had preceded the grant date. Therefore, the Group recognized compensation expense for these vested Sohu Video share-based awards and re-measured, and will re-measure, the compensation expense on each subsequent reporting date based on the then-current fair values of these vested awards until the grant date is established. |

| Taxation | Taxation PRC Corporate Income Taxes Income taxes are accounted for using an asset and liability approach which requires the recognition of income taxes payable or refundable for the current year and deferred tax liabilities and assets for the future tax consequences of events that have been recognized in the Group’s financial statements or tax returns. Deferred income taxes are determined based on the differences between the accounting basis and the tax basis of assets and liabilities and are measured using the currently enacted tax rates and laws. Deferred tax assets are reduced by a valuation allowance, if based on available evidence, it is considered that it is more likely than not that some portion of or all of the deferred tax assets will not be realized. In making such determination, the Group considers factors including future reversals of existing taxable temporary differences, future profitability, and tax planning strategies. If events were to occur in the future that would allow the Group to realize more of its deferred tax assets than the presently recorded net amount, an adjustment would be made to the deferred tax assets that would increase income for the period when those events occurred. If events were to occur in the future that would require the Group to realize less of its deferred tax assets than the presently recorded net amount, an adjustment would be made to the valuation allowance against deferred tax assets that would decrease income for the period when those events occurred. Significant management judgment is required in determining income tax expense and deferred tax assets and liabilities.
The Group’s deferred tax assets are related to net operating losses and temporary differences between accounting basis and tax basis for its China-Based Subsidiaries and VIEs, which are subject to corporate income tax in the PRC under the PRC Corporate Income Tax Law (the “CIT Law”). PRC Withholding Tax on Dividends The CIT Law imposes a 10% withholding income tax on dividends distributed by foreign invested enterprises in the PRC to their immediate holding companies outside Mainland China. A lower withholding tax rate may be applied if there is a tax treaty between Mainland China and the jurisdiction of the foreign holding company. A holding company in Hong Kong, for example, will be subject to a 5% withholding tax rate under an arrangement between the PRC and the Hong Kong Special Administrative Region on the “Avoidance of Double Taxation and Prevention of Fiscal Evasion with Respect to Taxes on Income,” if such holding company is considered a non-PRC resident enterprise and holds at least 25% of the equity interests in the PRC foreign invested enterprise distributing the dividends, subject to approval of the PRC local tax authority. However, if the Hong Kong holding company is not considered to be the beneficial owner of such dividends under applicable PRC tax regulations, such dividend will remain subject to a withholding tax rate of 10%. PRC Value Added Tax On May 1, 2016, the transition from the imposition of PRC business tax to the imposition of VAT was expanded to all industries in China, and all of the Sohu Group’s revenues have been subject to VAT since that date. To record VAT payable, the Group adopted the net presentation method, which presents the difference between the output VAT (at rates of 6% or 17% for the years ended December 31, 2016 and 2017 and for the period from January 1, 2018 to April 30, 2018, and at rates of 6% or 16% after May 1, 2018) and the available input VAT amount (at the rate applicable to the supplier). U.S. Corporate Income Tax Sohu.com Inc., which was formerly the top-tier publicly-traded parent company of the Sohu Group, was dissolved and liquidated on May 31, 2018. Sohu.com Inc. was a Delaware corporation that was subject to U.S. corporate income tax on its taxable income at a rate of 21% for taxable years beginning after December 31, 2017 and of up to 35% for prior tax years. U.S. federal tax legislation signed into law on December 22, 2017, commonly referred to as the Tax Cuts and Jobs Act (the “U.S. TCJA”), significantly modified the U.S. Internal Revenue Code by, among other things, reducing the maximum statutory U.S. federal corporate income tax rate from 35% to 21% for taxable years beginning after December 31, 2017; limiting and/or eliminating many business deductions; migrating the U.S. to a partial territorial tax system with a one-time transition tax (the “Toll Charge”) on a mandatory deemed repatriation of previously deferred foreign earnings of certain foreign subsidiaries; subject to certain limitations, generally eliminating U.S. corporate income tax on dividends from foreign subsidiaries; and providing for new taxes on certain foreign earnings. Certain activities conducted in the PRC resulted in U.S. corporate income taxes being imposed on Sohu.com Inc. when its subsidiaries that were controlled foreign corporations (“CFCs”) generated income that was subject to Subpart F of the U.S. Internal Revenue Code (“Subpart F”). Generally, passive income, such as rents, royalties, interest, dividends, and gains from disposal of the company’s investments, is among the types of income subject to taxation under Subpart F. Any income taxable under Subpart F was taxable in the U.S. at a federal corporate income tax rate of 21%. Subpart F income also included certain income from intra-Group transactions between Sohu.com Inc.’s non-U.S. subsidiaries and VIEs and Changyou’s non-U.S. subsidiaries and VIEs or Sogou’s non-U.S. subsidiaries and VIEs, or where Sohu.com Inc.’s non-U.S. subsidiaries or VIEs made an “investment in U.S. property,” such as holding the stock in, or making a loan to, a U.S. corporation. Under a provision of the U.S. tax code commonly referred to as the CFC look-through rule, Sohu.com Inc. did not have to treat dividends received by its CFC subsidiaries as Subpart F income includible in Sohu.com Inc.’s taxable income in the U.S. To the extent that portions of Sohu.com Inc.’s U.S. taxable income, such as Subpart F income or global intangible low-taxed income (“GILTI”), had been determined to be from sources outside of the U.S., subject to certain limitations, Sohu.com Inc. could claim foreign tax credits to offset its U.S. income tax liabilities. Following the enactment of the U.S. TCJA, if dividends that Sohu.com Inc. received from its subsidiaries after January 1, 2018 were determined to be from sources outside of the U.S., subject to certain limitations, Sohu.com Inc. would generally not have been required to pay U.S. corporate income tax on those dividends. Liabilities for U.S. corporate income tax were accrued in the Company’s consolidated statements of comprehensive income and estimated tax payments were made when required by U.S. law.
Treatment of Toll Charge Related to the U.S. TCJA Beginning in the fourth quarter of 2017, the Sohu Group had recognized a provisional amount of income tax expense for the Toll Charge of $219 million, which represented management’s estimate of the amount of the Toll Charge that would have been payable by Sohu.com Inc. based on the deemed repatriation to the United States of its share of previously deferred earnings of certain of its non-U.S. subsidiaries, offset by a reduction of $4 million in liability for deferred U.S. income tax, as a result of the U.S. TCJA. The Sohu Group included the provisional amount of the Toll Charge of $219 million in its interim financial statements through the quarter ended September 30, 2018, in reliance on Staff Accounting Bulletin No. 118 (“SAB 118”). For the fourth quarter of 2018, the Sohu Group’s management re-evaluated the impact on the Sohu Group of the Toll Charge under the U.S. TCJA. Management determined that it was more likely than not, based on the technical merits, that the tax position that the Sohu Group had no Toll Charge liability would be sustained. The Group recognized a tax benefit in the amount of $77 million, which was the largest amount that management determined to be greater than 50% likely to be realized upon settlement with the U.S. IRS. As a result, as of December 31, 2018 the Sohu Group had an unrecognized tax benefit in the amount of $142 million, which represented the difference between the tax benefit recognized in the fourth quarter of 2018 and management’s previous estimate of the Toll Charge. In addition, the Sohu Group accrued $2 million in interest on the unrecognized tax benefit. The tax benefit recognized and the unrecognized tax benefit in relation to the Toll Charge may be subject to further adjustment in subsequent periods based on facts and circumstances that arose after December 31, 2018, such as final IRS Toll Charge regulations published in February 2019, and any future circumstances such as any guidance issued by the U.S. Department of the Treasury, any U.S. IRS challenge of the Group’s position on the Toll Charge, and management’s further judgment and estimates. Uncertain Tax Positions The Sohu Group is subject to various taxes in different jurisdictions, primarily the U.S. and the PRC. Management reviews regularly the adequacy of the provisions for taxes as they relate to the Group’s income and transactions. In order to assess uncertain tax positions, the Group applies a more likely than not threshold and a two-step approach for tax position measurement and financial statement recognition. For the two-step approach, the first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount that is more than 50% likely to be realized upon settlement. |

| Net Income /(Loss) per Share | Net Income /(Loss) per Share Basic net income /(loss) per share is computed using the weighted average number of ordinary shares outstanding during the period. Diluted net income /(loss) per share is computed using the weighted average number of ordinary shares and, if dilutive, potential ordinary shares outstanding during the period. Potential ordinary shares comprise shares issuable upon the exercise or settlement of share-based awards using the treasury stock method. The dilutive effect of share-based awards with performance requirements is not considered before the performance targets are actually met. The computation of diluted net income /(loss) per share does not assume conversion, exercise, or contingent issuance of securities that would have an anti-dilutive effect (i.e. an increase in earnings per share amounts or a decrease in loss per share amounts) on net income /(loss) per share. Additionally, for purposes of calculating the numerator of diluted net income /(loss) per share, the net income /(loss) attributable to the Sohu Group is calculated as follows: Sogou’s net income /(loss) attributable to Sohu Before Sogou’s IPO Before Sogou’s IPO, Sogou’s net income /(loss) attributable to Sohu was determined using the percentage that the weighted average number of Sogou shares held by Sohu represented of the weighted average number of the Sogou Pre-IPO Preferred Shares and Pre-IPO Ordinary Shares, shares issuable upon the conversion of convertible preferred shares under the if-converted method, and shares issuable upon the exercise or settlement of share-based awards under the treasury stock method, and was not determined by allocating Sogou’s net income /(loss) to Sohu using the methodology for the calculation of net income /(loss) attributable to the Sogou noncontrolling shareholders. After Sogou’s IPO After Sogou’s IPO, Sogou’s net income /(loss) attributable to Sohu is determined using the percentage that the weighted average number of Sogou shares held by Sohu represents of the weighted average number of Sogou ordinary shares and shares issuable upon the exercise or settlement of share-based awards under the treasury stock method, and not by using the percentage held by Sohu of the total economic interest in Sogou, which is used for the calculation of basic net income per share. In the calculation of Sohu’s diluted net income /(loss) per share, assuming a dilutive effect, the percentage of Sohu’s shareholding in Sogou was calculated by treating convertible preferred shares issued by Sogou as having been converted at the beginning of the period and unvested Sogou share options with the performance targets achieved as well as vested but unexercised Sogou share options as having been exercised during the period. The dilutive effect of share-based awards with a performance requirement was not considered before the performance targets were actually met. Assuming an anti-dilutive effect, all of these Sogou shares and share options are excluded from the calculation of Sohu’s diluted income /(loss) per share. As a result, Sogou’s net income /(loss) attributable to Sohu on a diluted basis equals the number used for the calculation of Sohu’s basic net income /(loss) per share. Changyou’s net income /(loss) attributable to Sohu Changyou’s net income /(loss) attributable to Sohu is determined using the percentage that the weighted average number of Changyou shares held by Sohu represents of the weighted average number of Changyou ordinary shares and shares issuable upon the exercise or settlement of share-based awards under the treasury stock method, and not by using the percentage held by Sohu of the total economic interest in Changyou, which is used for the calculation of basic net income per share. In the calculation of Sohu’s diluted net income /(loss) per share, assuming a dilutive effect, all of Changyou’s existing unvested restricted share units and share options, and vested restricted share units and share options that have not yet been settled, are treated as vested and settled by Changyou under the treasury stock method, causing the percentage of the weighted average number of shares held by Sohu in Changyou to decrease. As a result, Changyou’s net income /(loss) attributable to Sohu on a diluted basis decreased accordingly. Assuming an anti-dilutive effect, all of these Changyou restricted share units and share options are excluded from the calculation of Sohu’s diluted net income /(loss) per share. As a result, Changyou’s net income /(loss) attributable to Sohu on a diluted basis equals the number used for the calculation of Sohu’s basic net income /(loss) per share. |

| Fair Value of Financial Instruments | Fair Value of Financial Instruments U.S. GAAP establishes a three-tier hierarchy to prioritize the inputs used in the valuation methodologies in measuring the fair value of financial instruments. This hierarchy also requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The three-tier fair value hierarchy is: Level 1 - observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets. Level 2 - include other inputs that are directly or indirectly observable in the market place. Level 3 - unobservable inputs which are supported by little or no market activity. The Sohu Group’s financial instruments consist primarily of cash equivalents, short-term investments, accounts receivable, financing receivables, prepaid and other current assets, long-term investments, restricted time deposits, accounts payable, accrued liabilities, receipts in advance and deferred revenue, short-term bank loans, other short-term liabilities, long-term bank loans and long-term accounts payable. |

| Accounts Receivable, Net | Accounts Receivable, Net The carrying value of accounts receivable is reduced by an allowance that reflects the Sohu Group’s best estimate of the amounts that will not be collected. The Group makes estimations of the collectability of accounts receivable. Many factors are considered in estimating the general allowance, including reviewing delinquent accounts receivable, performing an aging analysis and a customer credit analysis, and analyzing historical bad debt records and current economic trends. |

| Financing Receivables, Net |
Financing Receivables, Net Financing receivables consist primarily of small consumer loans to individual borrowers. Such amounts are recorded at the principal amount and interest accrued, net of allowance for credit losses that reflects Sogou’s best estimate of the amounts that will not be collected. Interest on loans is accrued based on the contractual interest rates of the loans when earned. The loan periods granted by Sogou to the borrowers related to the small consumer loans are generally within one year. The allowance for credit losses is determined at a level believed to be reasonable to absorb probable losses inherent in the loan portfolio as of each balance sheet date. The allowance is provided based on an assessment performed on a portfolio basis and is estimated on a quarterly basis or more often as necessary based on the delinquency rate, the aging of the amount due and other relevant factors. |

| Equity Investments | Equity Investments Investments in entities are recorded as equity investments under long-term investments. For entities over which the Group can exercise significant influence but does not own a majority equity interest or control, the equity method is applied, and the Group adjusts the carrying amount of an investment and recognizes investment income or loss for the Group’s share of the earnings or loss of the investee after the date of investment. For those equity investments accounted for other than under the equity method or those that result in consolidation, the fair value method is applied. However, for equity investments that do not have readily determinable fair values, the Group chooses to account for them at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer. If this measurement alternative is elected, changes in the carrying value of the equity investments will be required to be made whenever there are observable price changes in transactions for identical or similar investments of the same issuer. The implementation guidance notes that an entity should make a “reasonable effort” to identify price changes that are known or that can reasonably be known. |

| Long-Lived Assets | Long-Lived Assets Long-lived assets include fixed assets and intangible assets. Fixed Assets Fixed assets mainly comprise office buildings, leasehold improvements, building improvements, vehicles, office furniture and computer equipment, and hardware. Fixed assets are recorded at cost less accumulated depreciation with no residual value. Depreciation is computed using the straight-line method over the estimated useful lives of the assets.
Expenditure for maintenance and repairs is expensed as incurred. The gain or loss on the disposal of fixed assets is the difference between the net sale proceeds and the carrying amounts of the relevant assets and is recognized in operating expenses in the consolidated statements of comprehensive income.
Intangible Assets Intangible assets mainly comprise purchased video content, operating rights for licensed games, domain names and trademarks, computer software, and developed technologies. Intangible assets are recorded at cost less accumulated amortization with no residual value. Amortization of intangible assets other than purchased video content is computed using the straight-line method over their estimated useful lives. Amortization of purchased video content is computed based on the trend in viewership accumulation over the shorter of the applicable license period or two years. The estimated useful lives of the Group’s intangible assets are listed below:
Sohu Video enters into nonmonetary transactions to exchange online broadcasting rights for purchased video content with other online video broadcasting companies. Under ASC 845, the cost of a nonmonetary asset acquired in exchange for another nonmonetary asset is the fair value of the asset surrendered to obtain the acquired nonmonetary asset, and a gain or loss should be recognized on the exchange. The fair value of the asset received should be used to measure the cost if the fair value of the asset received is more reliable than the fair value of the asset surrendered. The Sohu Group records these nonmonetary exchanges at the fair values of the online broadcasting rights for purchased video content and recognize any net gain or loss from such exchange transactions. Impairment of Long-lived Assets other than Purchased Video Content In accordance with ASC 360-10-35, the Sohu Group reviews the carrying values of long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying value of an asset may not be recoverable. The evaluation is performed at the lowest level of identifiable cash flows independent of other assets. Recoverability of these assets is measured by a comparison of the carrying amounts to the future undiscounted cash flows the assets are expected to generate. If such review indicates that the carrying amount of the long-lived assets is not recoverable, the carrying amount of such assets is reduced to fair value. The estimation of future cash flows requires significant management judgment based on the Group’s historical results and anticipated results and is subject to many factors. The discount rate that is commensurate with the risk inherent in the Group’s business model is determined by its management. Impairment of Purchased Video Content Purchased video content is stated at the lower of cost less accumulated amortization, or net realizable value (“NRV”). In accordance with ASC 920-350-35, if management’s expectations of the programming usefulness of a program, series, package, or program segment are revised downward, it may be necessary to write down unamortized cost to estimated NRV. A write-down from unamortized cost to a lower estimated NRV establishes a new cost basis. Accordingly, the Group measures the video content’s impairment loss by comparing the content’s carrying value to its NRV. An impairment loss will be recorded if the carrying value of video content is higher than its NRV. The impairment to be recognized is measured by the amount by which the carrying value of video content exceeds its NRV. |

| Goodwill | Goodwill Goodwill represents the excess of the purchase price over the fair value of the identifiable assets and liabilities acquired as a result of the Sohu Group’s acquisitions of interests in its subsidiaries and consolidated VIEs. If the initial accounting for a business combination is incomplete by the end of the reporting period in which the combination occurs, the Group reports in its financial statements provisional amounts for the items for which the accounting is incomplete. If a measurement period adjustment is identified, the Group recognizes the adjustment as part of the acquisition accounting. The Sohu Group increases or decreases the provisional amounts of identifiable assets or liabilities by means of increases or decreases in goodwill for measurement period adjustments. In accordance with ASC 350, the Group does not amortize goodwill, but tests it for impairment. The Group tests goodwill for impairment at the reporting unit level on an annual basis as of October 1, and between annual tests when an event occurs or circumstances change that could indicate that the asset might be impaired. Under ASC 350-20-35, the Group has the option to choose whether it will apply a qualitative assessment first and then a quantitative assessment, if necessary, or to apply a quantitative assessment directly. For reporting units applying a qualitative assessment first, the Group starts the goodwill impairment test by assessing qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If it is more likely than not that the fair value of a reporting unit is less than its carrying amount, the quantitative impairment test is mandatory. Otherwise, no further testing is required. The quantitative impairment test consists of a comparison of the fair value of the reporting unit with its carrying value. For reporting units directly applying the quantitative assessment, the Group performs the two-step goodwill impairment test by first quantitatively comparing the fair values of those reporting units to their carrying amounts, including goodwill. After performing the assessment, if the carrying amounts of the reporting units are higher than their fair value, the Group performs the second step of the quantitative goodwill impairment test by comparing the implied fair value of the reporting unit’s goodwill with the carrying amount of that goodwill, and if the carrying amount of the reporting unit’s goodwill exceeds the implied fair value of that goodwill, an impairment loss is recognized in an amount equal to that excess. Application of a goodwill impairment test requires significant management judgment, including the identification of reporting units, assigning assets and liabilities to reporting units, assigning goodwill to reporting units, and determining the fair value of each reporting unit. The Group estimates fair value using the income approach and the market approach. The judgment in estimating the fair value of reporting units includes estimating future cash flows, determining appropriate discount rates, control premium, comparable companies’ multipliers, and making other assumptions. Changes in these estimates and assumptions could materially affect the determination of fair value for each reporting unit. |

| Functional Currency and Foreign Currency Translation | Functional Currency and Foreign Currency Translation An entity’s functional currency is the currency of the primary economic environment in which it operates, normally that is the currency of the environment in which the entity primarily generates and expends cash. Management’s judgment is essential to determine the functional currency by assessing various indicators, such as cash flows, sales price and market, expenses, financing and intra-Group transactions and arrangements. The functional currency of Sohu.com Limited, and its predecessor Sohu.com Inc., is the U.S. dollar. The functional currency of the Sohu Group’s subsidiaries in the U.S., the Cayman Islands, the British Virgin Islands and Hong Kong is the U.S. dollar. The functional currencies of the Sohu Group’s subsidiaries and VIEs in other countries are the national currencies of those counties, rather than the U.S. dollar. Foreign currency transactions denominated in currencies other than the functional currency are translated into the functional currency using the exchange rates prevailing at the dates of the transactions. Monetary assets and liabilities denominated in foreign currencies at the balance sheet date are re-measured at the applicable rates of exchange in effect at that date. Gains and losses resulting from foreign currency re-measurement are included in the consolidated statements of comprehensive income. Financial statements of entities with a functional currency other than the U.S. dollar are translated into U.S. dollars, which is the reporting currency. Assets and liabilities are translated at the current exchange rate in effect at the balance sheet date, and revenues and expenses are translated at the average of the exchange rates in effect during the reporting period. Shareholders’ equity accounts are translated using the historical exchange rates at the date the entry to shareholders’ equity was recorded, except for the change in retained earnings during the year, which is translated using the historical exchange rates used to translate each period’s income statement. Differences resulting from translating a foreign currency to the reporting currency are recorded in accumulated other comprehensive income in the consolidated balance sheets. |

| Impact of Recently Issued Accounting Pronouncements | Impact of Recently Issued Accounting Pronouncements Revenue from Contracts with Customers. In May 2014, the FASB issued Accounting Standards Update (“ASU”) No. 2014-09, ‘‘Revenue from Contracts with Customers (Topic 606).’’ This guidance supersedes current guidance on revenue recognition in Topic 605, ‘‘Revenue Recognition.’’ In addition, there are disclosure requirements related to the nature, amount, timing, and uncertainty of revenue recognition. On January 1, 2018, the Sohu Group adopted ASC 606, applying the modified retrospective method to contracts that were not completed as of January 1, 2018. The adoption did not have a material impact on retained earnings as of January 1, 2018. Results for reporting periods beginning on or after January 1, 2018 are presented under ASC 606, while prior period amounts are not adjusted and continue to be reported in accordance with the Group’s historic accounting under ASC 605. Additional disclosures have been made. Please see the Notes to Consolidated Financial Statements for details. Financial Instruments (Subtopic 825-10). In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments- Recognition and Measurement of Financial Assets and Financial Liabilities. This new guidance amends certain aspects of recognition, measurement, presentation and disclosure of financial instruments. The main provisions require equity investments (except those accounted for under the equity method of accounting or those that result in consolidation of the investee) to be measured at fair value through earnings, unless they qualify for a measurement alternative. The new guidance will require a modified retrospective application to all outstanding instruments beginning January 1, 2018, with a cumulative effect adjustment recorded to opening retained earnings as of the beginning of the first period in which the guidance becomes effective. However, changes to the accounting for equity securities without a readily determinable fair value will be applied prospectively. Additional disclosures have been made. Please see the Notes to Consolidated Financial Statements for details. Statements of Cash Flows (Topic 230): Restricted Cash. In November 2016, the FASB issued ASU No. 2016-18, Statements of Cash Flows (Topic 230): Restricted Cash. This guidance requires that a statement of cash flows explain the changes during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statements of cash flows. The standard is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. The standard should be applied to each period presented using a retrospective transition method. The adoption of this standard resulted in restricted cash and restricted time deposits being included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statements of cash flows. Please See Note 10. Other accounting standards adopted beginning January 1, 2018 do not have a significant impact on the Sohu Group’s consolidated financial statements. |

| Impact of Recently Issued Accounting Pronouncements not Yet Adopted | Impact of Recently Issued Accounting Pronouncements not Yet Adopted Leases. On February 25, 2016, the FASB issued ASU No. 2016-02, Leases, which requires an entity to recognize both assets and liabilities arising from finance and operating leases, along with additional qualitative and quantitative disclosures. ASU No. 2016-02 requires a lessee to recognize a liability in its balance sheet to make lease payments (a “lease liability”) and a right-of-use asset representing its right to use the underlying asset for the lease term. In transition, lessees and lessors are required to recognize and measure leases at the beginning of the earliest comparative period presented, or at the beginning of the period of adoption. ASU 2016-02 is required to be adopted at the beginning of the first quarter of fiscal year 2019. The Sohu Group expects to record a right-of-use asset of approximately $26.7 million and a lease liability of approximately $24.2 million on ASU 2016-02’s adoption date of January 1, 2019, primarily related to the Sohu Group’s leased office space. The Sohu Group will use a modified retrospective approach and will not restate prior periods. The Sohu Group expects to implement new accounting policies as well as to elect certain practical expedients available to it under ASU 2016-02, including those related to capitalization thresholds and leases with terms of less than 12 months. The Sohu Group’s implementation of the amended lease guidance is subject to the same internal controls over financial reporting that it applies to its consolidated financial statements. Financial Instruments-Credit Losses. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments-Credit Losses (Topic 326), which requires entities to measure all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. This replaces the existing incurred loss model and is applicable to the measurement of credit losses on financial assets measured at amortized cost. This guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Early application will be permitted for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. The Sohu Group does not expect to adopt ASU 2016-13 early and is currently evaluating the impact that the standard will have on its consolidated financial statements and related disclosures. Simplifying the Test for Goodwill Impairment. In January 2017, the FASB issued ASU No. 2017-04, “Simplifying the Test for Goodwill Impairment.” The guidance removes Step 2 of the goodwill impairment test, which requires a hypothetical purchase price allocation. A goodwill impairment will now be the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. The guidance should be adopted on a prospective basis for the annual or any interim goodwill impairment tests beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The Sohu Group does not expect to adopt ASU 2017-04 early and is currently evaluating the impact of adopting this standard on its consolidated financial statements. |

Note (1): The increase for 2018 compared to 2017 mainly consisted of $33.4 million in income earned from investments in financial instruments. Note (2): The increase for 2018 compared to 2017 mainly consisted of $17.8 million in investment income recognized in the third quarter of 2018 by Sogou due to the observable change in the price of Zhihu Technology Limited (“Zhihu”) after the adoption of ASU 2016-01, offset by a $3.6 million investment loss representing a change in the fair value of Hylink Digital Solution Co., Ltd (“Hylink”). Note (3): In the second quarter of 2016, the Sohu Group recognized a one-time expense of $27.8 million that was related to a donation by Sogou to Tsinghua University related to setting up a joint research institute focusing on artificial intelligence technology. Note (4): Before the adoption of ASU 2016-01, the Group recognized an other than temporary impairment loss of $5.8 million in the third quarter of 2017 that was related to Keyeast Co., Ltd. (“Keyeast”), an investment measured as available-for-sale equity securities. The Sohu Group reported the investment at fair value using a market approach based on Keyeast’s stock price on the South Korean stock market. The fair value was continually below its original cost for a twelve-month period ended July 31, 2017. Management considered the decline in the fair value to be other-than-temporary. |

Note (2): The change was mainly due to additional income withholding tax of $47 million that was recognized in the first quarter of 2018 due to a revised policy for Changyou’s PRC subsidiaries with respect to their distribution of cash dividends. The revised policy was adopted to facilitate the distribution of a special cash dividend in the aggregate amount of approximately $500.0 million that was declared by Changyou’s Board of Directors on April 5, 2018. |
