The Company and Basis of Presentation	'
	1. The Company and Basis of Presentation
	Nature of Operations
	Sohu.com Inc. (“Sohu” or the “Company”), a Delaware corporation organized in 1996, is a leading online media, search, gaming, community and mobile service group providing comprehensive online products and services in the People’s Republic of China (the “PRC” or “China”). The Company, together with its wholly-owned and majority-owned subsidiaries and variable interest entities (collectively the “Sohu Group” or the “Group”), mainly offers online advertising services, online game services and mobile services.
	Online advertising and online games are the core businesses of the Sohu Group.
	Online Advertising
	The online advertising business consists of the brand advertising business as well as the search and others business.
	Brand Advertising Business
	The brand advertising business offers advertisements on the Sohu Group’s Web properties to companies seeking to increase their brand awareness online.
	Search and Others Business
	The search and others business, provided by Sohu’s search subsidiary Sogou Inc. (“Sogou”), primarily offers customers pay-for-click services, as well as online marketing services on the Sogou Web Directory.
	On September 16, 2013, pursuant to a Subscription Agreement entered into on that date by and among Sogou, THL A21 Limited, a British Virgin Islands company which is a wholly-owned subsidiary of Tencent Holdings Limited, a Cayman Islands company (Tencent Holdings Limited together with its subsidiaries, Tencent”); Sohu’s wholly-owned subsidiary Sohu.com (Search) Limited, a Cayman Islands company (“Sohu Search”); and Photon Group Limited (“Photon”), the investment vehicle of the Sohu Group’ s Chairman and Chief Executive Officer Dr. Charles Zhang, and a series of other contracts also entered into on that date between Sogou and Tencent, Tencent invested a net amount of $448 million in cash in Sogou and transferred its Soso search-related businesses and certain other assets to Sogou (collectively, the “Sogou-Tencent Transactions,” or the “Transactions”).
	On September 16, 2013, Sogou entered into (i) a Repurchase Option Agreement with Sohu Search, exercisable commencing March 16, 2014, granting to Sogou the right to purchase 24 million Series A Preferred Shares of Sogou held by Sohu Search for an aggregate purchase price of $78.8 million; (ii) a Repurchase Option Agreement with Photon, also exercisable commencing March 16, 2014, granting to Sogou the right to purchase 6.4 million Series A Preferred Shares of Sogou held by Photon for an aggregate purchase price of $21 million; and (iii) a Repurchase/put Option Agreement with China Web Search (HK) Limited (“China Web”), an investment vehicle of Yunfeng Capital, granting to Sogou the right to purchase at any time from March 16, 2014 to July 31, 2014, and granting to China Web the right to put to Sogou at any time prior to July 31, 2014, 14.4 million Series A Preferred Shares of Sogou held by China Web for an aggregate purchase price of $47.3 million. Sogou expects to exercise its rights under each of these agreements when they first become exercisable.
	On September 16, 2013, Sogou, Sohu Search, Photon, Mr. Xiaochuan Wang, four other members of Sogou’s management (collectively, the “Sohu Parties”) and Tencent entered into a Shareholders Agreement (the “Shareholders Agreement”). Under the Shareholders Agreement, the parties have agreed to vote their Sogou voting shares in all elections of directors to elect three designees of Sohu Search and two designees of Tencent.
	On September 17, 2013, Sogou paid a special dividend to the three holders of Series A Preferred Shares of Sogou in an aggregate amount of $301 million, of which Sohu received $161 million, Photon received $43 million, and China Web received $97 million.
	Pursuant to the Shareholders Agreement, Sohu will hold approximately 53.6% of the total voting power for the election of the Board of Directors of Sogou, assuming that the repurchase options and the repurchase/put option are exercised, Tencent’s non-voting Class B Ordinary Shares are converted to voting shares, and all share options under the Sogou 2010 Share Incentive Plan and all share options under an arrangement providing for Sogou share-based awards to Sohu management and key employees (the “Management Share Option Arrangement”) are granted and exercised. As Sohu is the controlling shareholder of Sogou, Sohu consolidates Sogou in the Sohu Group’s consolidated financial statements, and recognizes noncontrolling interest reflecting economic interests in Sogou held by shareholders other than Sohu.

	Online Games
	The online game business is conducted by Sohu’s majority-owned subsidiary Changyou.com Limited (“Changyou”). Changyou completed its initial public offering (“IPO”) on the NASDAQ Global Select Market under the symbol “CYOU” in 2009. As of September 30, 2013, Sohu held approximately 68% of the combined total of Changyou’s outstanding ordinary shares and controlled approximately 83% of the total voting power in Changyou. As Changyou’s controlling shareholder, Sohu consolidates Changyou in the Sohu Group’s consolidated financial statements but recognizes noncontrolling interest reflecting the economic interest in Changyou held by shareholders other than Sohu.
	The online game business consists of the development, operation and licensing of massively multiplayer online games (“MMOGs”), which are interactive online games that may be played simultaneously by hundreds of thousands of game players, Web games, which are played over the Internet using a Web browser, and mobile games. Changyou currently operates several MMOGs in China, including the in-house developed Tian Long Ba Bu (“TLBB”), and developed, and primarily jointly operates with third-party joint operators, DDTank and Wartune (also known as “Shen Qu”), which are two popular Web games in China.
	Basis of Consolidation
	The consolidated financial statements include the accounts of Sohu and its wholly-owned and majority-owned subsidiaries and consolidated VIEs. All intercompany transactions are eliminated.
	VIE Consolidation
	The Sohu Group adopted the guidance of accounting for VIEs, which requires VIEs to be consolidated by the primary beneficiary of the entity. 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. The Sohu Group has one VIE that is not consolidated since the Group is not the primary beneficiary.
	Noncontrolling Interest Recognition
	Noncontrolling interests are recognized to reflect the portion of the equity of majority-owned subsidiaries and VIEs which is not attributable, directly or indirectly, to the controlling shareholders.
	Basis of Presentation
	These financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. These financial statements should be read in conjunction with the consolidated financial statements and related footnotes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2012.
	The accompanying unaudited condensed consolidated interim financial statements reflect all normal recurring adjustments which, in the opinion of management, are necessary for a fair statement of the results for the interim periods presented. Results for the nine months ended September 30, 2013 are not necessarily indicative of the results expected for the full fiscal year or for any future period. Certain comparative figures have been reclassified to conform to the current presentation.
	Historical accounting error regarding net income attributable to Sohu.com Inc. and basic and diluted net income per share attributable to Sohu.com Inc.
	In the third quarter of 2013, as previously reported in an Amendment No. 1 to Current Report on Form 8-K/a that the Company filed with the SEC on September 20, 2013, management noted an accounting error in the Company’s Quarterly Report on Form 10-Q for the three months ended June 30, 2012 regarding net income attributable to Sohu.com Inc. and the calculation of basic and diluted net income per share attributable to Sohu.com Inc. In June 2012, Sohu had purchased from Alibaba Investments Limited (“Alibaba”), a private investment subsidiary of Alibaba Group Holding Limited, 24.0 million Series A Preferred Shares of Sogou for cash consideration of $25.8 million. Under ASC 260-10-S99-2, this transaction gave rise to a deemed dividend in the amount of $14.2 million, which was the difference between the consideration Sohu paid to Alibaba and the carrying amount of these 24.0 million Series A Preferred Shares in the Group’s consolidated financial statements. Accordingly, this amount of $14.2 million should have been subtracted from net income to arrive at net income available to common shareholders in the Group’s calculation of net income per share. This deemed dividend was inappropriately accounted for when calculating the net income attributable to the Group, resulting in an error in the calculation of basic and diluted net income per share attributable to Sohu.com Inc. There was a carry-forward effect of this accounting error to the net income attributable to Sohu.com Inc. and the net income per share calculation as reported for the nine months ended September 30, 2012 in the Company’s Quarterly Report on Form 10-Q for the three months then ended (the “3rd Quarter 2012 10-Q”), and as reported for the year ended December 31, 2012 in the Company’s Annual Report on Form 10-K for the year then ended. In addition, there was a carry-forward effect of the error to the classification of retained earnings and additional paid-in capital in the Company’s Quarterly Report on Form 10-Q for the three months ended June 30, 2012, September 30, 2012, March 31, 2013 and June 30, 2013, and the Company’s Annual Report on Form 10-K for the year ended December 31, 2012.
	Management performed an assessment of the impact of this accounting error from both a quantitative and a qualitative perspective in accordance with the guidance contained in SAB 99, and concluded that the error was not material to the Group’s relevant historical financial statements taken as a whole. Therefore, management concluded that the relevant affected historical financial statements could continue to be relied upon but would be revised to correct the error.
	Correction of the error in the Group’s consolidated statements of comprehensive income for the nine months ended September 30, 2012 included in this report resulted in a reduction of $14.2 million in the amount reported for net income attributable to Sohu.com Inc. (from $61.8 million to $47.6 million) and a reduction of $0.38 in the amounts reported for both basic net income per share and diluted net income per share attributable to Sohu.com Inc. (from $1.63 to $1.25 for basic net income per share, and from $1.44 to $1.06 for diluted net income per share), as compared to the corresponding amounts reported in the 3rd Quarter 2012 10-Q. Correction of the error in the Group’s consolidated balance sheets as of December 31, 2012 included in this report resulted in an increase of $14.2 million in additional paid-in capital (from $364.1 million to $378.3 million) and a reduction of $14.2 million in retained earnings (from $784.4 million to $770.2 million), as compared to the corresponding amounts reported in the Company’s Annual Report on Form 10-K for the year ended December 31, 2012.
	Reclassification of revenues and costs related to Changyou Internet value-added services (“IVAS”)
	Commencing January 1, 2013, in order to provide a better foundation for understanding Changyou’s performance, both revenues and costs generated from the operation of third-party Web games by the 17173 business were reclassified from the online game business to IVAS in the others business. To conform to current period presentations, the relevant amounts for prior periods have been reclassified accordingly. Such reclassifications amounted to $0.8 million and $3.5 million, respectively, for revenues and $0.3 million and $1.3 million for costs, respectively, for the three and nine months ended September 30, 2012.

ShareBased_Compensation_Expens

Share-Based Compensation Expense	9 Months Ended
Share-Based Compensation Expense	Sep. 30, 2013
Share-Based Compensation Expense [Abstract]	'
Share-Based Compensation Expense	'
	3. Share-Based Compensation Expense
	Sohu, Changyou, Sogou, Fox Video Limited (“Sohu Video”), and 7Road.com Limited (“7Road”) all have incentive plans for the granting of share-based awards, including common stock /ordinary shares, share options, restricted shares and restricted share units, to their executive officers, management and employees.
	Sohu, Changyou, and Sogou share-based awards
	For Sohu, Changyou and Sogou, share-based compensation expense is recognized as costs and /or expenses in the consolidated statements of comprehensive income based on the fair value of the related share-based awards on their grant dates. Share-based compensation expense is charged to the shareholders’ equity or noncontrolling interest section in the consolidated balance sheets.
	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 (amounting to 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 September 30, 2013, grants of options for the purchase of 15,352,200 of ordinary shares of Sohu Video had been made and were effective under the Video 2011 Share Incentive Plan.
	For purposes of ASC 718, no grant date may be established until mutual understanding of the option awards’ key terms and conditions between Sohu Video and the recipients can be reached, and such mutual understanding cannot be reached until the enterprise value of Sohu Video and hence the fair value of the options is determinable and can be accounted for.
	Management concluded that as of September 30, 2013 certain significant factors necessary to determine the fair value of Sohu’s video division remained uncertain. On the basis that the broader terms and conditions of the option awards had neither been finalized nor mutually agreed with the recipients, no grant of options occurred for purposes of ASC 718 and hence no share-based compensation expense was recognized for the three months ended September 30, 2013.
	7Road share-based awards
	On July 10, 2012, 7Road adopted a 2012 Share Incentive Plan (the “7Road 2012 Share Incentive Plan”), which initially provided for the issuance to selected directors, officers, employees, consultants and advisors of 7Road of up to 5,100,000 ordinary shares of 7Road (amounting to 5.1% of the then outstanding 7Road shares on a fully-diluted basis). On November 2, 2012, 7Road’s Board of Directors and its shareholders approved an increase from 5,100,000 to 15,100,000 ordinary shares (amounting to 13.7% of the then outstanding 7Road shares on a fully-diluted basis) under the 7Road 2012 Share Incentive Plan.
	On May 1, 2013, Changyou entered into an agreement to acquire all of the outstanding ordinary shares of 7Road held by noncontrolling shareholders. The acquisition closed on June 5, 2013.
	On June 28, 2013, 7Road’s Board of Directors approved the cancellation of the 7Road 2012 Share Incentive Plan. 7Road concurrently offered to a total of 42 7Road employees holding an aggregate of 2,223,750 restricted share units which had been granted under the 7Road 2012 Share Incentive Plan the right to exchange their restricted share units for, at each employee’s election, in each case subject to the employee’s continued employment by 7Road, either (i) Scheme I: the right to a cash payment of up to an aggregate of $2.90 per restricted share unit exchanged, vesting and payable at the rate of 40%, 30% and 30%, respectively, on the first, second and third anniversaries of July 18, 2012, which is the date when the surrendered restricted share units were granted under the 7Road 2012 Share Incentive Plan, or (ii) Scheme II: the right to receive an annual cash bonus, over a seven-year period commencing July 1, 2013, based on adjusted annual cumulative net income of 7Road. All restricted share units held by these 42 holders under the 7Road 2012 Share Incentive Plan as of June 28, 2013 were included in this exchange program.

	As the original awards of restricted share units made under the 7Road 2012 Share Incentive Plan included as a vesting condition the completion of an IPO, which is not considered probable under it occurs, no share-based compensation expense was recognized for the fair value of the original awards. As of the date of the modification resulting from the exchange program, incremental compensation expense, which is not classified as share-based compensation expense, will be the fair values of the two new compensation schemes included in the exchange program.
	For Scheme I, the modification resulted in total incremental compensation expense of $5.7 million, which will be recognized in the consolidated statements of comprehensive income ratably over the remaining vesting period of the awards for each tranche. For the three and nine months ended September 30, 2013, compensation expense of $0.4 million and $2.9 million, respectively, was recognized in the consolidated statements of comprehensive income. In the third quarter of 2013, 7Road paid $1.6 million in cash bonuses under Scheme I.
	For Scheme II, the incremental compensation expense varies depending on 7Road’s financial performance. In the third quarter of 2013, 7Road granted to an additional 48 7Road employees the right to receive an annual cash bonus under Scheme II with the same terms as described above. For both the three and the nine months ended September 30, 2013, compensation expense of $0.3 million was recognized in the consolidated statements of comprehensive income.

	4. Fair Value Measurements
	Fair Value of Financial Instruments
	The Sohu Group’s financial instruments include cash equivalents, restricted time deposits, short-term investments, investments in debt securities, accounts receivable, prepaid and other current assets, prepaid non-current assets, 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, as well as the repurchase options and the repurchase/put option with respect to Sogou Series A Preferred Shares.

	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 following table sets forth the financial instruments, measured at fair value, by level within the fair value hierarchy as of September 30, 2013 (in thousands):

	Cash equivalents
	The Sohu Group’s cash equivalents mainly consist of time deposits placed with banks with an original maturity of three months or less. The fair value of time deposits is determined based on the pervasive interest rates in the market, which are also the interest rates as stated in the contracts with the banks. 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 time deposits at the reporting date. In order to determine the fair value, the Group must use 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.
	Restricted time deposits
	Restricted time deposits are valued based on the prevailing interest rates in the market. 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 2012 and 2013, Changyou drew down loans from offshore branches of certain banks for the purposes of expediting the payment of a special one-time cash dividend to its shareholders, providing working capital to support its overseas operations, funding the acquisition of outstanding noncontrolling interests in 7Road and providing capital to support its share repurchase program. These bank loans were secured by an equivalent or greater amount of RMB deposits by Changyou in the onshore branches of such banks. The loans from the offshore branches of the lending banks are classified as short-term bank loans or long-term bank loans based on their payment terms.
As of September 30, 2013, the total amount of the bank loans was $354 million, of which $252 million carried a floating rate of interest based on the London Inter-Bank Offered Rate (“LIBOR”) and $102 million carried a fixed rate of interest. For the three and nine months ended September 30, 2013, interest income from the restricted time deposits securing the loans was $2.9 million and $8.8 million, respectively, and interest expense on the bank loans was $2.3 million and $6.4 million, respectively. All of outstanding balances of the bank loans are repayable in 2014.
Collateral related to Sogou incentive shares trust arrangements
In February 2013, Sohu deposited $9 million in cash into restricted time deposit accounts at a bank as collateral for credit facilities provided by the bank to certain Sogou employees. The facilities were intended to fund the employees’ early exercise of Sogou share options and related PRC individual income tax. Sohu is not subject to any additional potential payments other than the restricted time deposit amounts, and believes that the fair value of its guarantee liability is immaterial.
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 September 30, 2013, the Sohu Group’s investments in financial instruments were mainly held by 7Road and totaled approximately $24.4 million. The investments are issued by commercial banks in China with 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 three and nine months ended September 30, 2013, the Group recorded in the consolidated statements of comprehensive income change in the fair value of short-term investments in the amount of $0.8 million and $2.3 million, respectively. For the three and nine months ended September 30, 2012, the Group recorded in the consolidated statements of comprehensive income change in the fair value of short-term investments in the amount of $0.4 million and $1.0 million, respectively.
Investments in debt securities
In September 2010, Sohu purchased from a PRC-based company (the “Debtor”) a convertible debt security in the principal amount of $74.6 million (or RMB0.5 billion) with interest, payable quarterly in cash, of 3.8% per annum and an initial maturity of twelve months, subject to extension in Sohu’s sole discretion for additional sequential six-month periods. The Debtor’s obligations on the debt are secured by a pledge from the Debtor’s parent company of its entire equity interest in the Debtor. In September 2011, March 2012, September 2012, March 2013 and September 2013, Sohu extended the maturity of the security for sequential six-month periods, to March 2012, September 2012, March 2013, September 2013 and March 2014, respectively, with an interest rate of 6.8% per annum. Under the terms of the security, if Sohu continues to extend the maturity of the security to March 31, 2014, it will have the option, exercisable on March 31, 2014, to convert the outstanding principal into fixed percentages of equity interests in two companies which are affiliates of the Debtor.

For the three and nine months ended September 30, 2013, interest income generated from this debt security amounted to $1.40 million and $4.14 million, respectively. For the three and nine months ended September 30, 2012, interest income generated from this debt security amounted to $1.37 million and $4.10 million, respectively.
The Sohu Group elected the fair value option to account for its investments in debt securities at their initial recognition. Changes in fair value were recognized in other income /(expense). For the three and nine months ended September 30, 2013 and 2012, there was no change in fair value. To estimate fair value, the Group used the income approach, which considers the estimated future return from the investment and the probabilities of getting these returns. The Group classifies the valuation techniques that use these inputs as Level 3 of fair value measurements.
Repurchase Options and Repurchase/Put Option for Sogou Series A Preferred Shares
As discussed in Note 1 - The Company and Basis of Presentation, in September 2013 Sogou entered into Repurchase Option Agreements with Sohu Search and Photon, and a Repurchase/put Option Agreement with China Web with respect to Series A Preferred Shares of Sogou held by them. Sogou expects to exercise its rights to purchase Series A Preferred Shares under each of these agreements when they first become exercisable by Sogou on March 16, 2014.
The repurchase options and the repurchase/put option for Sogou Series A Preferred Shares were initially recognized in the Sohu Group’s consolidated balance sheets at fair value when the agreements were signed. The fair value of the put option will be revaluated quarterly until the option is exercised or expires unexercised. Subsequent changes in the fair values of the equity classified repurchase options will not be recognized until the options are exercised. Management determined the fair values of these options determined using the binominal model, with a discount for lack of marketability, given that the repurchase options and the repurchase/put option were not publicly traded at the time of grant, and made the determination with the assistance of a qualified professional appraiser using management’s estimates and assumptions. We classify the valuation techniques that use these inputs as Level 3 of fair value measurements.
As of September 30, 2013, the Sohu Group recognized $6.2 million for the put option in other short-term liabilities. Any changes in the fair value of the put option were recognized in other income /(expense). For the three months ended September 30, 2013, fair value change of $144,000 for the put option was recognized in other expense in the consolidated statement of comprehensive income. As of September 30, 2013, the Sohu Group also recognized $3.7 million for the repurchase options in additional paid-in capital in equity, based on the fair value of the repurchase options on September 16, 2013.
Other financial instruments
The following are other financial instruments not measured at fair value in the consolidated balance sheets, but for which the fair value was estimated for disclosure purposes.
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 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 classifies the valuation techniques that use these inputs as Level 2 of fair value measurements. For other short-term receivables and payables, the Group estimated fair values using the discounted cash flow method, which is unobservable in the market. The Group classifies the valuation technique as Level 3 of fair value measurements.
Prepaid non-current assets and long-term payables
Prepaid non-current assets are financial assets with carrying values that approximate fair value because the impact of applying a discount rate to the carrying values would be immaterial. Long-term accounts payable and long-term bank loans are financial liabilities with carrying values that approximate fair value due to the change in fair value, after considering the discount rate, being immaterial.
For long-term bank loans, the rates of interest under Changyou’s agreements with lending banks were determined based on the prevailing interest rates in the market. The Sohu Group classifies the valuation techniques that use these inputs as Level 2 of fair value measurements. For prepaid non-current assets and 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 3 of fair value measurements.

	In May 2013, the office building Sohu purchased in 2009 was placed in service. Accordingly, in the same month, the Sohu Group recognized the office building’s original cost of $162 million as fixed assets. The original cost consists primarily of the purchase price and the costs of technological infrastructure and fitting-out work. Also in May 2013, the Group began recognizing depreciation expense based on the building’s useful life, which is approximately 41 years, on a straight-line basis.
	For Changyou’s office building purchased in 2010, as of September 30, 2013, all of the $164 million purchase price had been paid and recognized as construction-in-process under fixed assets in the Sohu Group’s consolidated balance sheets, as the construction of the building had been completed and the technological infrastructure and fitting-out work was still in progress.

	Sohu.com Inc. and Changyou.com (US) Inc. are subject to income taxes in the United States (“U.S.”). 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.
	The Sohu Group did not have any penalties or significant interest associated with tax positions for the three and nine months ended September 30, 2013, nor did the Group have any significant unrecognized uncertain tax positions for the three and nine months ended September 30, 2013.
	PRC Corporate Income Tax
	Related to High and New Technology Enterprises
	The PRC Corporate Income Tax Law (the “CIT Law”) applies an income tax rate of 25% to all enterprises but grants preferential tax treatment to High and New Technology Enterprises (“NHTEs”). Under this preferential tax treatment, NHTEs can enjoy a preferential income tax rate of 15% for three years, but need to re-apply after the end of the three-year period. The CIT Law went into effect on January 1, 2008.

	Within the Sohu Group, five enterprises, consisting of Beijing Sohu New Era Information Technology Co., Ltd. (“Sohu Era”), Beijing Sohu New Media Information Technology Co., Ltd. (“Sohu Media”), Beijing Sogou Technology Development Co., Ltd. (“Sogou Technology”), Changyou’s China-based subsidiary Beijing AmazGame Age Internet Technology Co., Ltd. (“AmazGame”) and Changyou’s China-based VIE Beijing Gamease Age Digital Technology Co., Ltd. (“Gamease”), qualified as NHTEs in 2008 and qualified upon re-application in 2011. Therefore, for these enterprises the income tax rate is 15% for 2013. These enterprises will need to re-apply for NHTE status in 2014.
	Two additional enterprises, Beijing Sohu Internet Information Service Co., Ltd. (“Sohu Internet”) and Beijing Sogou Information Service Co., Ltd. (“Sogou Information”), qualified as NHTEs in 2009 and qualified upon re-application in 2012. Therefore, for these enterprises the income tax rate is 15% for 2013 and 2014. These enterprises will need to re-apply for NHTE status in 2015.
	Related to Software Enterprises
	Under the CIT Law, a Software Enterprise can enjoy an income tax exemption for two years beginning with its first profitable year and a 50% tax reduction to a rate of 12.5% for the subsequent three years.
	As of September 30, 2013, Shenzhen 7Road Technology Co., Ltd (“Shenzhen 7Road”), Beijing Changyou Gamespace Software Technology Co., Ltd. (“Gamespace”), ICE Information Technology (Shanghai) Co., Ltd. (“ICE Information”), Shanghai ICE Information Technology Co., Ltd. (“Shanghai ICE”) and Shenzhen 7Road Network Technologies Co., Ltd. (“7Road Technology”) were “Software Enterprises” entitled to the beneficial tax treatment described above.
	PRC Withholding Tax on Dividends
	The CIT Law imposes a 10% withholding income tax for dividends distributed by foreign invested enterprises to their immediate holding companies outside mainland China. A lower withholding tax rate will be applied if there is a tax treaty arrangement 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 the 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 and Capital (the “China-HK Tax Arrangement”) 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 may remain subject to a withholding tax rate of 10%.
	As of September 30, 2013, Changyou accrued deferred tax liabilities in the amount of $16.8 million for PRC withholding tax.
	Transition from PRC Business Tax to PRC Value Added Tax
	Effective September 1, 2012, a Pilot Program for transition from the imposition of PRC business tax (“Business Tax”) to the imposition of value added tax (“VAT”) for revenues from certain industries was expanded from Shanghai to eight other cities and provinces in China, including Beijing and Tianjin. Commencing August 1, 2013 the Pilot Program was expanded to all regions in the PRC. The Sohu Group’s brand advertising and search revenues are subject to this program.
	Business Tax had been imposed primarily on revenues from the provision of taxable services, assignments of intangible assets and transfers of real estate. Prior to the implementation of the Pilot Program, the Sohu Group’s Business Tax rate, which varies depending on the nature of the revenues being taxed, generally ranged from 3% to 5%.
	VAT payable on goods sold or taxable labor services provided by a general VAT taxpayer for a taxable period is the net balance of the output VAT for the period after crediting the balance of VAT input. Before the implementation of the Pilot Program, the Sohu Group was mainly subject to a small amount of VAT for revenues of Changyou’s subsidiary 7Road that are deemed for PRC tax purposes to be derived from the sale of software. VAT has been imposed on those 7Road revenues at a rate of 17%, with a 14% immediate tax refund, resulting in a net rate of 3%. With the implementation of the Pilot Program, in addition to the revenues currently subject to VAT, the Group’s brand advertising and search revenues are in the scope of the Pilot Program and are now subject to VAT at a rate of 6%.

	Under ASC 605-45, the presentation of taxes on either a gross basis (included in revenues and costs) or a net basis (excluded from revenues) is an accounting policy decision determined by management. As VAT imposed on brand adverting and search revenues and VAT imposed on 7Road’s revenues from the sale of software are considered as substantially different in nature, the Sohu Group determined that it is reasonable to apply the guidance separately for these two types of VAT. The basis for this determination is that VAT payable on brand advertising and search revenues is the difference between the output VAT (at a rate of 6%) and available input VAT amount (at the rate applicable to the supplier), which is a component of the Group’s costs for providing the brand advertising and search services. On the other hand, the VAT payable by 7Road is in effect at 3% of the applicable revenues from the sale of software, irrespective of the availability of any input VAT, under preferential VAT treatment provided to 7Road by the local tax bureau. In this regard, the Group believes the VAT payable by 7Road is more akin to a sales tax than typical VAT. As a result, the Group adopted the net presentation method for its brand advertising and search businesses both before and after the implementation of the Pilot Program, and for the revenues of 7Road deemed to be derived from the sale of software, the Group adopted the gross presentation method before and after the implementation of the Pilot Program.
	U.S. Corporate Income Tax
	Sohu.com Inc. is a Delaware corporation that is subject to U.S. corporate income tax on its taxable income at a rate of 34% or 35%. Subject to certain limitations, the net operating losses (“NOLs”) of a corporation taxable in the U.S. that are carried forward from prior years may be used to offset the corporation’s taxable income. At the end of the 2012 taxable year, Sohu.com Inc. had no further NOLs available for offsetting any U.S. taxable income. Accordingly, to the extent that it has U.S. taxable income in 2013, the Sohu Group will accrue U.S. corporate income tax in its consolidated statements of comprehensive income and make estimated tax payments as and when required by U.S. law.
	Other Provisions for Taxes
	As described above, the Group is subject to various taxes in different jurisdictions, primarily the US and the PRC. Management reviews regularly the adequacy of the provisions for taxes as they relate to the income and transactions of the Group. In reviewing various equity transactions among companies in the Group, management determined that the transactions may result in additional tax obligations under relevant tax rules. As a result of certain equity transactions that took place during the quarter ended September 30, 2013, the Group has recognized directly to equity a provision for tax in the amount of $21.4 million as of September 30, 2013.

	Unconditional Obligations
	As of September 30, 2013, the Sohu Group had commitments for bandwidth purchases in the amount of $44 million, commitments for operating leases in the amount of $28 million, commitments for video content purchases in the amount of $22 million and commitments for other content and service purchases in the amount of $16 million.
	Litigation
	The Sohu Group is a party to various litigation matters which it considers routine and incidental to its business. Management does not expect the results of any of these actions to have a material adverse effect on the Group’s business, results of operations, financial condition and cash flows.
	In the first quarter of 2013, the Sohu Group settled lawsuits with four major record companies (Sony BMG, Warner, Universal and Gold Label) without any payment of damages. In these lawsuits, which were initiated against the Sohu Group in March 2008, these record companies had alleged that the Sohu Group provided music search links and download services that violated copyrights they owned.
	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 others, online game, mobile and others 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. Certain risks related to PRC law that could affect the Sohu Group’s VIE structure are discussed in Note 9 - 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 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.
	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.

	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. The Sohu Group has one VIE that is not consolidated in the Group’s consolidated financial statements because the Group is not 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 are directly or indirectly owned by Dr. Charles Zhang, Sohu’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 those 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 September 30, 2013, the aggregate amount of these loans was $18.6 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 September 30, 2013, the registered capital and PRC statutory reserves of the consolidated VIEs totaled $34.8 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 following is a summary of the consolidated VIEs within the Sohu Group:

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 laws and regulations prohibiting or restricting foreign ownership of companies that engage in such operations and businesses. If such a finding were made, regulatory authorities with jurisdiction over the licensing and operation of such operations businesses would have broad discretion in dealing with such a violation, including levying fines, confiscating the Group’s income, revoking the business or operating licenses of the affected businesses, requiring the Group to restructure its ownership structure or operations, or requiring the Group to discontinue all or any portion of its operations. Any of these actions could cause significant disruption to the Group’s business operations, and have a materially adverse impact on the Group’s cash flows, financial position and operating performance. The management considers the possibility of such a finding by PRC regulatory authorities to be remote.
In addition, it is possible that the contracts with 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 laws 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 Group would not be able to exert effective control over the affected VIEs. Consequently, such VIE’s results of operations, assets and liabilities would not be included in the Sohu Group’s consolidated financial statements. If such were the case, the Group’s cash flows, financial position and operating performance would be materially adversely affected. The Sohu Group’s contractual arrangements with respect to its consolidated VIEs are approved and in place. The 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.
VIE Not Consolidated within the Sohu Group
In December 2012, the Sohu Group acquired, for a price of $1.6 million, a 25% equity interest in a VIE to support the Group’s brand advertising business. Since the Sohu Group neither controls nor has significant influence over this VIE, the Group is not the primary beneficiary and, accordingly, the Group recognizes the investment under the equity method. In assessing its maximum exposure to a loss on the investment compared to the cost of its investment, the Sohu Group determined that it did not have further obligations exceeding the cost of the investment and that there were no terms of the investment arrangement that could require the Sohu Group to provide further financial support to the VIE.

Takeover Defense

Sohu intends to adopt appropriate defensive measures in the future on a case by case basis as and to the extent that Sohu’s Board of Directors determines that such measures are necessary or advisable to protect Sohu stockholder value in the face of any coercive takeover threats or to prevent an acquirer from gaining control of Sohu without offering fair and adequate price and terms.

On July 27, 2013, Changyou’s Board of Directors authorized a share repurchase program of up to $100 million of the outstanding ADSs of Changyou over a two-year period from July 27, 2013 to July 26, 2015.

2) Changyou.com Limited Share-based Awards

Changyou’s 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 ordinary shares, including those issued pursuant to the exercise of share options and upon vesting and settlement of restricted share units. In March 2009, the 2,000,000 reserved ordinary shares were subject to a ten-for-one share split effected by Changyou and became 20,000,000 ordinary shares. Most of these awards vest over a period of four years. The maximum term of any issued share right under the Changyou 2008 Share Incentive Plan is ten years from the grant date. The Changyou 2008 Share Incentive Plan will expire in August 2018.

3) Sogou Inc. Share-based Awards

Sogou 2010 Share Incentive Plan

On October 20, 2010, Sogou adopted the Sogou 2010 Share Incentive Plan (the “Sogou 2010 Share Incentive Plan”). On June 18, 2013, the Sogou 2010 Share Incentive Plan was amended to provide for the issuance of up to 36,000,000 ordinary shares of Sogou to management and key employees of Sogou and of any present or future parents or subsidiaries or variable interest entities of Sogou. The maximum term of any issued share right under the amended Sogou 2010 Share Incentive Plan is ten years from the grant date. The amended Sogou 2010 Share Incentive Plan will expire on October 19, 2020. As of September 30, 2013, Sogou had issued options for the purchase of 35,436,375 ordinary shares.

Of the 35,436,375 issued share options, 23,206,375 share options will become vested and exercisable in four equal installments, with each installment vesting upon a service period requirement for management and key employees being met, as well as Sogou’s achievement of performance targets for the corresponding period. The performance target for each installment will be set at the beginning of each vesting period; therefore, for purposes of recognition of share-based compensation expense, each installment is considered to be granted at that date. As of September 30, 2013, performance targets had been set for 15,790,400 share options and, accordingly, those options subject to vesting upon service period requirements for management and key employees being met and Sogou’s achievement of performance targets were considered granted for purposes of recognition of share-based compensation expense. As of September 30, 2013, 10,040,650 share options had become vested and exercisable because both the service period and the performance requirements had been met, and a portion of the vested shares had been exercised.

8,270,000 share options will become vested and exercisable in four or five equal installments, with (i) the first installment vesting upon Sogou’s completion of an initial public offering of its ordinary shares (“Sogou’s IPO”) and the expiration of all underwriters’ lockup periods applicable to the IPO, and (ii) each of the three or four subsequent installments vesting on the first, second, third and, if applicable, fourth anniversary dates, respectively, of the closing of Sogou’s IPO.

The remaining 3,960,000 share options will become vested and exercisable in four equal installments, with (i) the first installment vesting upon the first anniversary of the occurrence of either of the following events (“Event”): (a) completion of Sogou’s IPO; (b) the consolidation of Sogou with or the acquisition of Sogou by another person or entity in a sale of all or substantially all of its assets or shares, and (ii) each of the three subsequent installments vesting on the second, third and fourth anniversary dates, respectively, of the occurrence of an Event. If there has not been an Event within 24 months from June 15, 2013 (the “Vesting Cessation Date”), all installments of the remaining 3,960,000 share options will cease to vest.

All installments of the 8,270,000 and 3,960,000 share options that are subject to vesting upon the completion of Sogou’s IPO or an Event were considered granted upon the issuance of the options. The completion of a firm commitment IPO or such an Event is considered to be a performance condition of the awards. An IPO event or such an Event is not considered to be probable until it is completed. Under ASC 718, compensation cost should be accrued if it is probable that the performance condition will be achieved and should not be accrued if it is not probable that the performance condition will be achieved. As a result, no compensation expense will be recognized related to these options until the completion of an IPO or the occurrence of an Event, and hence no share-based compensation expense was recognized for the three and nine months ended September 30, 2013 for the 8,270,000 and 3,960,000 share options that are subject to vesting upon the completion of Sogou’s IPO or an Event.

For the three and nine months ended September 30, 2013, total share-based compensation expense recognized for share options under the amended Sogou 2010 Share Incentive Plan was $1.7 million and $1.8 million, respectively. For the three and nine months ended September 30, 2012, total share-based compensation expense recognized for share options under the Sogou 2010 Share Incentive Plan was $1.4 million and $2.4 million, respectively.

As of September 30, 2013, there was $2.0 million of unrecognized compensation expense related to the unvested share options. The expense is expected to be recognized over a weighted average period of 0.27 years.

The fair value of the ordinary shares of Sogou was assessed using the income approach /discounted cash flow method, with a discount for lack of marketability, given that the shares underlying the award were not publicly traded at the time of grant, and was determined with the assistance of a qualified professional appraiser using management’s estimates and assumptions. This 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.

The fair value of the options granted to Sogou management and key employees was estimated on the date of grant using the Binomial option - pricing model (the “BP Model”) with the following assumptions used:

1.3%~6.0%

Weighted average expected option life

Volatility rate

Sogou estimated the risk free rate based on the yield to maturity of China Sovereign bonds denominated in United States dollars as of the valuation date. An exercise multiple was estimated as the ratio of fair value of the shares over the exercise price as of the time the option is exercised, based on consideration of research studies regarding exercise patterns based on historical statistical data. In Sogou’s valuation analysis, a multiple of two was applied for employees and a multiple of three was applied for management. Sogou estimated the forfeiture rate to be 1.3% for Sogou management’s share options granted as of September 30, 2013 and 6.0% for Sogou employees’ share options granted as of September 30, 2013. The life of the share options is the contract life of the option. Based on the option agreement, the contract life of the option is 10 years. The expected volatility at the valuation date was estimated based on the historical volatility of comparable companies for the period before the grant date with length commensurate with the expected term of the options. Sogou has no history or expectation of paying dividends on its ordinary shares. Accordingly, the dividend yield is estimated to be 0%.

Share-based Awards to Sohu management

Under the Management Share Option Arrangement approved by the Board of Directors of Sohu and Sogou in March 2011, Sohu has the right to provide to Sohu management and key employees the opportunity to purchase from Sohu up to 12,000,000 ordinary shares of Sogou at a fixed exercise price of $0.625 per share. Of these 12,000,000 ordinary shares, 8,800,000 are Sogou ordinary shares previously held by Sohu and 3,200,000 are Sogou 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 million. As of September 30, 2013, Sohu had issued options for the purchase of 11,378,500 Sogou ordinary shares to Sohu management and key employees under this arrangement.

Of the 11,378,500 issued share options, 8,978,500 share options will become vested and exercisable in four equal installments, with each installment vesting upon a service period requirement for management and key employees being met, as well as Sogou’s achievement of performance targets for the corresponding period. The performance target for each installment will be set at the beginning of each vesting period; therefore, for purposes of recognition of share-based compensation expense, each installment is considered to be granted at that date. As of September 30, 2013, performance targets had been set for 6,585,750 share options and, accordingly, those options vesting upon service period requirements for management and key employees being met and Sogou’s achievement of performance targets were considered granted. As of September 30, 2013, 5,105,500 share options had become vested and exercisable because both the service period and the performance requirements had been met, and all of the vested shares had been exercised.

The remaining 2,400,000 share options will become vested and exercisable in five equal installments, with (i) the first installment vesting upon Sogou’s IPO and the expiration of all underwriters’ lockup periods applicable to the IPO, and (ii) each of the four subsequent installments vesting on the first, second, third and fourth anniversary dates, respectively, of the closing of Sogou’s IPO. All installments of the 2,400,000 share options that are subject to vesting upon the completion of Sogou’s IPO were considered granted upon the issuance of the options. The completion of a firm commitment IPO is considered to be a performance condition of the awards. An IPO event is not considered to be probable until it is completed. Under ASC 718, compensation cost should be accrued if it is probable that the performance condition will be achieved and should not be accrued if it is not probable that the performance condition will be achieved. As a result, no compensation expense will be recognized related to these options until the completion of an IPO, and hence no share-based compensation expense was recognized for the three and nine months ended September 30, 2013, for the 2,400,000 share options that are subject to vesting upon the completion of Sogou’s IPO.

For the three months and the nine months ended September 30, 2012, total share-based compensation expense recognized for share options under the Management Share Option Arrangement was $200,000 and $382,000, respectively.

Option Modification

In the first and second quarter of 2013, a portion of the share options granted under the amended Sogou 2010 Share Incentive Plan and the Management Share Option Arrangement were exercised early, and the resulting Sogou ordinary shares were transferred to a trust with the original option grantees as beneficiaries. The trust will distribute the shares to those beneficiaries in installments based on the vesting requirements under the original option agreements. Although this trust arrangement caused a modification of the terms of these share options, the modification was not considered substantive; therefore no incremental fair value related to these shares resulted from the modification, and the remaining share-based compensation expense for these shares will continue to be recognized over the original remaining vesting period.

As of September 30, 2013, 19,245,000 share options granted under the amended Sogou 2010 Share Incentive Plan and 1,225,000 share options granted under the Management Share Option Arrangement, or a total of 20,470,000 share options, were exercised early.

	Sogou Transactions
	On October 22, 2010, Sogou issued and sold 24.0 million, 14.4 million and 38.4 million, respectively, of its newly-issued Series A Preferred Shares to Alibaba, China Web and Photon for $15 million, $9 million, and $24 million, respectively. On June 29, 2012, Sohu purchased Alibaba’s 24.0 million Sogou Series A Preferred Shares for a purchase price of $25.8 million.
	On September 16, 2013, Sogou entered into a series of agreements with Tencent, Sohu Search and Photon pursuant to which Sogou issued Series B Preferred Shares and Class B Ordinary Shares to Tencent for a net amount of $448 million in cash and Tencent transferred its Soso search-related businesses and certain other assets to Sogou. Also on that date, Sogou entered into Repurchase Option Agreements with Sohu Search and Photon, and a Repurchase/put Option Agreement with China Web, with respect to all of the Series A Preferred Shares of Sogou held by Sohu Search and China Web, and a portion of the Series A Preferred Shares of Sogou held by Photon. On September 17, 2013, Sogou paid a special dividend to the three holders of Series A Preferred Shares of Sogou in an aggregate amount of $301 million, of which Sohu received $161 million, Photon received $43 million, and China Web received $97 million. See Note 1 - The Company and Basis of Presentation.
	As of September 30, 2013, Sogou had outstanding a combined total of 370,771,658 ordinary shares and preferred shares, consisting of shares held as follows:

	(i)	Sohu: 134,107,750 Class A Ordinary Shares and 24,000,000 Series A Preferred Shares. Of the Class A Ordinary Shares, 6,907,750 shares are subject to purchase under options held by Sohu management and key employees. All of the 24,000,000 Series A Preferred Shares are subject to repurchase by Sogou commencing March 16, 2014;

	(ii)	Photon: 38,400,000 Series A Preferred Shares, of which 6,400,000 are subject to repurchase by Sogou commencing March 16, 2014;

	(iii)	China Web: 14,400,000 Series A Preferred Shares, all of which are subject to China Web’s right to put the shares to Sogou at any time prior to July 31, 2014 and all of which are subject to repurchase by Sogou at any time from March 16, 2014 to July 31, 2014;

	(iv)	Tencent: 79,368,421 non-voting Class B Ordinary Shares and 65,431,579 Series B Preferred Shares; and

	(v)	Certain employees of Sogou and Sohu: 15,063,908 Class A Ordinary Shares.
	As Sohu is Sogou’s controlling shareholder, Sohu consolidates Sogou in the Sohu Group’s consolidated financial statements, and recognizes noncontrolling interest reflecting economic interests in Sogou held by shareholders other than Sohu.
	As of September 30, 2013, a portion of Sogou options granted to Sogou and Sohu top management and key employees were still unvested and were settable upon the achievement of different vesting conditions. Because no ordinary shares will be issued with respect to share options granted by Sogou until they are vested and exercised, the share options granted by Sogou that have not vested and vested share options that have not yet been exercised are not included as outstanding shares of Sogou and have no impact on the Sohu Group’s basic net income per share. Unvested share options with the performance targets achieved and vested share options that have not yet been exercised do, however, have a dilutive impact on the Sohu Group’s dilutive net income per share. See Note 15 - Net Income per Share.
	Terms of Preferred Shares of Sogou
	In connection with the Sogou-Tencent Transactions, Sogou’s shareholders adopted a Fifth Amended and Restated Memorandum of Association and Second Amended and Restated Articles of Association (together, the “Revised Sogou Memorandum and Articles”), which became effective on September 16, 2013. The following is a summary of some of the key terms of the Sogou Series A Preferred Shares and Series B Preferred Shares (collectively, the “Preferred Shares”) under the Revised Sogou Memorandum and Articles.
	Dividend Rights
	Sogou may not declare or pay dividends on its Class A Ordinary Shares or Class B Ordinary Shares (collectively, “Ordinary Shares”) unless the holders of the Preferred Shares then outstanding first receive a dividend on each outstanding Preferred Share in an amount at least equal to the sum of (i) the dividends that would have been payable to the holder of such Preferred Share if such share had been converted into Ordinary Shares, at the then-applicable conversion rate, immediately prior to the record date for such dividend, and (ii) all accrued and unpaid Accruing Dividends. “Accruing Dividends” are calculated from the date of issuance of the Series A Preferred Shares at the rate per annum of $0.0375 per Series A Preferred Share and from the date of issuance of the Series B Preferred Shares at the rate per annum of $0.411 per Series B Preferred Share.

	Liquidation Rights
	In the event of any “Liquidation Event,” such as the liquidation, dissolution or winding up of Sogou, a merger or consolidation of Sogou resulting in a change of control, the sale of substantially all of Sogou’s assets or similar events, the holders of Series B Preferred Shares are entitled to receive an amount per share equal to the greater of (i) $6.847 plus any unpaid Accruing Dividends or (ii) such amount per share as would have been payable if the Series B Preferred Shares had been converted into Ordinary Shares prior the Liquidation Event, and holders of Series A Preferred Shares are entitled to receive, after payment to the holders of the Series B Preferred Shares but before any payment to holders of Ordinary Shares, an amount equal to the greater of (i) 1.3 times their original investment in the Series A Preferred Shares plus all accrued but unpaid Accruing Dividends or (ii) such amount per share as would be payable if the Series A Preferred Shares had been converted into Ordinary Shares immediately prior to the Liquidation Event.
	Redemption Rights
	The Preferred Shares are not redeemable at the option of the holders.
	Conversion Rights
	Each Preferred Share is convertible, at the option of the holder, at any time, and without the payment of additional consideration by the holder. Each Preferred Share is convertible into such number of Class A Ordinary Shares as is determined, in the case of Series A Preferred Shares, by dividing $0.625 by the then-effective conversion price for Series A Preferred Shares, which is initially $0.625, and, in the case of Series B Preferred Shares, by dividing $7.267 by the then-effective conversion price for Series B Preferred Shares, which is initially $7.267. The conversion prices of the Preferred Shares are subject to adjustment on a weighted average basis upon the issuance of additional equity shares, or securities convertible into equity shares, at a price per share less than $0.625, in the case of Series A Preferred Shares, or less than $7.267, in the case of Series B Preferred Shares, subject to certain customary exceptions, such as shares issued pursuant to the amended Sogou 2010 Share Incentive Plan. Each Preferred Share will be automatically converted into Class A Ordinary Shares of Sogou upon the closing of a qualified initial public offering of Sogou based on the then-effective conversion ratio of such Preferred Share, which is currently one-for-one for both Series A Preferred Shares and Series B Preferred Shares.
	Voting Rights
	Each holder of Preferred Shares is entitled to cast the number of votes equal to the number of Class A Ordinary Shares into which the Preferred Shares held by such holder are then convertible.
	Other Rights
	The holders of Preferred Shares have various other rights typical of preferred share investments.
	Terms of Class B Ordinary Shares of Sogou
	The Class B Ordinary Shares have rights identical to those of the Class A Ordinary Shares, except that Class B Ordinary Shares do not have voting rights unless the holders of at least a majority of the then outstanding Class B Ordinary Shares elect, by written notice to Sogou, to convert them into shares with voting rights.
	7Road Transactions
	On May 1, 2013, Changyou entered into an agreement to acquire all of the ordinary shares of 7Road held by the noncontrolling shareholders, representing 28.074% of the outstanding share capital of 7Road, for aggregate cash consideration of approximately $78 million. The acquisition closed on June 5, 2013. Effective with the closing, 7Road became an indirect wholly-owned subsidiary of Changyou, and Changyou’s VIE Gamease became the sole shareholder of 7Road’s VIE Shenzhen 7Road. As of September 30, 2013, Changyou had paid $76 million of the total cash consideration. The remaining $2 million will be settled in June 2014.

	12. Business Combination
	On September 16, 2013, as part of the Sogou-Tencent Transactions, Sogou acquired from certain subsidiaries of Tencent, Shi Ji Guang Su, which conducts Soso search-related businesses, and other related assets, for cash consideration of approximately $27.6 million (the “Shi Ji Guang Su Acquisition”). As of September 30, 2013, Sogou had paid $3.3 million of the consideration. The remaining amount will be settled prior to March 16, 2014. The Sohu Group began to consolidate Shi Ji Guang Su’s financial statements commencing September 16, 2013.

	On the acquisition date, the allocation of the consideration of the assets acquired and liabilities assumed based on their fair value was as follows (in thousands):


		As of September 16, 2013
	Cash	$	3,249
	Receivables		7,967
	Fixed assets acquired		21,964
	Goodwill		2,405
	Identifiable intangible assets acquired		5,686
	Liabilities		(13,653	)

	Total	$	27,618

	The fixed assets acquired in the Shi Ji Guang Su Acquisition consist primarily of computer equipment and hardware. The identifiable intangible assets acquired in the Shi Ji Guang Su Acquisition consist primarily of developed technologies, trademarks and domain names. These identifiable intangible assets were valued using the income approach. The excess of the purchase price over identifiable tangible and intangible assets acquired and identifiable liabilities assumed was recorded as goodwill, which is not amortized but is tested for impairment.
	Based on an assessment of the acquired company’s financial performance, the acquired company is not considered material to the Sohu Group. Thus the Sohu Group’s management concluded that the presentation of pro forma financial information with respect to the results of operations of the Sohu Group including the acquired company is not necessary.

Mezzanine Equity [Abstract]	'
Mezzanine Equity	'
	13. Mezzanine Equity
	Mezzanine Equity consists of noncontrolling interest in 7Road and a put option pursuant to which the former noncontrolling shareholders would have had the right to put their ordinary shares in 7Road to Changyou at a pre-determined price if 7Road had achieved specified performance milestones before the expiration of the put option and 7Road did not complete an IPO on NASDAQ, the NYSE or the HKEX. The put option was due to expire in 2014. Since the occurrence of the sale was not solely within the control of Changyou, the noncontrolling interest was classified as mezzanine equity instead of permanent equity in the Sohu Group’s and Changyou’s consolidated financial statements.
	Under ASC 480-10, the Sohu Group calculates, on an accumulative basis from the acquisition date, (i) the amount of accretion that would increase the balance of noncontrolling interest to its estimated redemption value over the period from the date of the Shenzhen 7Road acquisition to the earliest redemption date of the noncontrolling interest in 7Road and (ii) the amount of net profit attributable to noncontrolling shareholders of 7Road based on their ownership percentage. The carrying value of the noncontrolling interest as mezzanine equity is adjusted by an accumulative amount equal to the higher of (i) and (ii).
	On May 1, 2013, Changyou entered into an agreement to acquire all of the ordinary shares of 7Road held by the noncontrolling shareholders. The acquisition closed on June 5, 2013. Under ASC 810-10, changes in a parent’s ownership interest while the parent retains control of its subsidiary are accounted for as equity transactions, and do not impact net income or comprehensive income in the consolidated financial statements. Following the closing of the acquisition, $2.4 million, representing the excess of the amount of the mezzanine-classified noncontrolling interest in 7Road over the purchase price as of the closing date, was recorded in the Sohu Group’s equity accounts.
	For the three and nine months ended September 30, 2013, accretion charges of nil and $17.8 million, respectively, compared to $4.5 million and $6.7 million, respectively, for the three and nine months ended September 30, 2012, were recorded in the Sohu Group’s statements of comprehensive income as net income attributable to the mezzanine-classified noncontrolling interest shareholders of 7Road.

Noncontrolling Interest	'
	14. Noncontrolling Interest
	The primary majority-owned subsidiaries and VIEs of the Sohu Group which are consolidated in its consolidated financial statements but with noncontrolling interest recognized are Changyou and Sogou.

	Noncontrolling Interest for Changyou
	As Sohu is Changyou’s controlling shareholder, Changyou’s financial results have been consolidated with those of Sohu for all periods presented. To reflect the economic interest in Changyou held by shareholders other than Sohu (the “Changyou noncontrolling shareholders”), Changyou’s net income attributable to the Changyou noncontrolling shareholders is recorded as noncontrolling interest in the Sohu Group’s consolidated statements of comprehensive income, based on their 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 Sohu’s ownership in Changyou, are recorded as noncontrolling interest in the Sohu Group’s consolidated balance sheets.
	Noncontrolling Interest for Sogou
	As Sohu is Sogou’s controlling shareholder, Sogou’s financial results have been consolidated with those of Sohu for all periods presented. To reflect the economic interest in Sogou held by shareholders other than Sohu (the “Sogou noncontrolling shareholders”), Sogou’s net income /(loss) attributable to the Sogou noncontrolling shareholders is recorded as noncontrolling interest in the Sohu Group’s consolidated statements of comprehensive income. Sogou’s cumulative results of operations attributable to the Sogou noncontrolling shareholders, along with changes in shareholders’ equity /(deficit) and adjustment for share-based compensation expense in relation to those share-based awards which are unvested and vested but not yet settled and the Sogou noncontrolling shareholders’ original investments in Series A Preferred Shares, Series B Preferred Shares and Class B Ordinary Shares are accounted for as a noncontrolling interest classified as permanent equity in the Sohu Group’s consolidated balance sheets, as redemption of the noncontrolling interest is solely within the control of Sohu. These treatments are based on the terms governing investment by the Sogou noncontrolling shareholders in the Preferred Shares of Sogou (the “Terms of Preferred Shares of Sogou”), the terms of Sogou’s restructuring in 2010, Sohu’s purchase of Sogou Series A Preferred Shares from Alibaba, and the terms of Class B Ordinary Shares of Sogou.
	By virtue of these terms, as Sogou has been losing money since its restructuring in 2010, the net losses have been and will be allocated in the following order:

	(i)	net losses were allocated to holders of Sogou Class A Ordinary Shares and the holder of Sogou Class B Ordinary Shares until their basis in Sogou decreased to zero;

	(ii)	additional net losses were allocated to holders of Sogou Series A Preferred Shares until their basis in Sogou decreased to zero;

	(iii)	additional net losses will be allocated to the holder of Sogou Series B Preferred Shares until its basis in Sogou decreases to zero; and

	(iv)	further net losses will be allocated between Sohu and noncontrolling shareholders based on their shareholding percentage in Sogou.
	Any subsequent net income from Sogou will be allocated in the following order:

	(i)	net income will be allocated between Sohu and noncontrolling shareholders based on their shareholding percentage in Sogou until their basis in Sogou increases to zero;

	(ii)	additional net income will be allocated to the holder of Sogou Series B Preferred Shares to bring its basis back;

	(iii)	additional net income will be allocated to holders of Sogou Series A Preferred Shares to bring their basis back;

	(iv)	further net income will be allocated to holders of Sogou Class A Ordinary Shares and the holder of Sogou Class B Ordinary Shares to bring their basis back; and

	(v)	further net income will be allocated between Sohu and noncontrolling shareholders based on their shareholding percentage in Sogou.
	Noncontrolling Interest in the Consolidated Balance Sheets
	As of September 30, 2013 and December 31, 2012, noncontrolling interest in the consolidated balance sheets was $481.8 million and $231.0 million, respectively.


			As of
			September 30, 2013			December 31, 2012

	Total		$	481,825		$	230,994


	Noncontrolling Interest of Changyou
	As of September 30, 2013 and December 31, 2012, noncontrolling interest of Changyou of $279.1 million and $204.0 million, respectively, was recognized in the Sohu Group’s consolidated balance sheets, representing a 32% economic interest in Changyou’s net assets held by shareholders other than Sohu and reflecting the reclassification of Changyou’s share-based compensation expense from shareholders’ additional paid-in capital to noncontrolling interest.
	Noncontrolling Interest of Sogou
	As of September 30, 2013 and December 31, 2012, noncontrolling interest of Sogou of $200.3 million and $24.6 million, respectively, was recognized in the Sohu Group’s consolidated balance sheets, representing Sogou’s cumulative results of operations attributable to shareholders other than Sohu, Sogou’s share-based compensation expense, and the investments of shareholders other than Sohu in Series A Preferred Shares, Series B Preferred Shares and Class B Ordinary Shares of Sogou, and the adjustment of the investment basis of shareholders other than Sohu due to the special dividend paid to holders of Series A Preferred Shares of Sogou on September 17, 2013. The increase from December 31, 2012 to September 30, 2013 was mainly due to the net impact of Tencent’s investment in Sogou on September 16, 2013, and the adjustment of the investment basis of shareholders other than Sohu due to the special dividend paid to holders of Series A Preferred Shares of Sogou on September 17, 2013.
	Noncontrolling Interest in the Consolidated Statements of Comprehensive Income
	For the three and nine months ended September 30, 2013, net income attributable to noncontrolling interests in the consolidated statements of comprehensive income was $22.9 million and $70.4 million, respectively, compared with $21.1 million and $57.6 million, respectively, for the three months and nine months ended September 30, 2012.

	Noncontrolling Interest of Sogou
	For the three months ended September 30, 2013 and 2012, $1.1 million and $2.2 million, respectively, in net loss attributable to the noncontrolling interest of Sogou was recognized in the Sohu Group’s consolidated statements of comprehensive income, representing Sogou’s net loss attributable to shareholders other than Sohu.

Net Income per Share [Abstract]	'
Net Income per Share	'
	15. Net Income per Share
	Basic net income per share is computed using the weighted average number of common shares outstanding during the period. Diluted net income per share is computed using the weighted average number of common shares and, if dilutive, potential common shares outstanding during the period. Potential common 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 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 per share. Additionally, for purposes of calculating the numerator of diluted net income per share, the net income attributable to the Sohu Group is adjusted as follows:

	-1	Changyou’s net income attributable to the Sohu Group 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, instead of by the percentage held by Sohu of the total economic interest in Changyou, which is used for the calculation of basic net income per share.

	For the third quarter of 2013, the percentage used for the calculation of basic and dilutive net income per share was 67.6% and 67.2%, respectively. In the calculation of the Sohu Group’s diluted net income per share, all of Changyou’s existing unvested restricted share units, and vested restricted share units 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 from 67.6% to 67.2%. As a result, Changyou’s net income attributable to the Sohu Group on a diluted basis decreased accordingly. This impact is presented as “incremental dilution from Changyou” in the table below.

	-2	Sogou’s net income /(loss) attributable to the Sohu Group 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, Series A Preferred Shares, Series B Preferred 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, instead of by Sogou’s net income /(loss) allocated to the Sohu Group by virtue of the Terms of Preferred Shares of Sogou, the terms of Sogou’s restructuring in 2010, Sohu’s purchase of Sogou Series A Preferred Shares from Alibaba, and the terms of Class B Ordinary Shares of Sogou, which is used for the calculation of basic net income per share.
	In the calculation of the Sohu Group’s basic net income per share, Sogou’s net income /(loss) attributable to the Group is determined according to the Terms of Preferred Shares of Sogou, the terms of Sogou’s restructuring in 2010, Sohu’s purchase of Sogou Series A Preferred Shares from Alibaba, and the terms of Class B Ordinary Shares of Sogou. For the third quarter of 2013, in the calculation of the Sohu Group’s diluted net income per share, assuming a dilutive effect, the percentage of 63% was calculated by treating convertible preferred shares issued by Sogou as having been converted at the beginning of the period and unvested share options with the performance targets achieved as well as vested but unexercised 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 above difference is presented as “incremental dilution from Sogou” in the table below.
	As discussed in Note 1 - The Company and Basis of Presentation, on June 29, 2012, Sohu purchased 24 million Sogou Series A Preferred Shares from Alibaba, and this transaction gave rise to a deemed dividend amounting to $14.2 million, which was the difference between the price Sohu paid to Alibaba for the Series A Preferred Shares and the carrying amount of these 24.0 million Series A Preferred Shares in the Group’s consolidated financial statements. This deemed dividend has been subtracted from the Net income attributable to Sohu.com Inc. for the nine months ended September 30, 2012 in the table below, to revise the historical inappropriate treatment when calculating the basic and diluted net income per share attributable to Sohu.com Inc.
	The portion of the special dividend paid by Sogou on September 17, 2013 to holders of Series A Preferred Shares of Sogou other than Sohu, in the amount of $139.7 million, is a payment to noncontrolling preferred shareholders, of which Sohu, as a holder of ordinary shares of Sogou, is deemed to have contributed $82.4 million. This $82.4 million has also been subtracted from the Net income attributable to Sohu.com Inc. for the three months and nine months ended September 30, 2013 to arrive at net income available to ordinary shareholders in the calculation of net income per share attributable to Sohu.com Inc.
	The following table presents the calculation of the Sohu Group’s basic and diluted net income per share (in thousands, except per share data).
