The Company and Basis of Presentation [Abstract]	'
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 Chinese online media, search and game service group providing comprehensive online products and services on PCs and mobile devices 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 and online game 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 Sohu Group’s brand advertising business offers to its users, over its matrices of Chinese language Web content and services, various products and services (such as free of charge content, including news, video, interactive community and other competitive Internet services) across multiple Internet-enabled devices, such as PCs, mobile phones and tablets. It also offers advertisements on Sohu Group Web properties to companies mainly 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 wholly-owned subsidiary of Tencent Holdings Limited (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”).
	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.
	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 which the parties 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 the aggregate amount of $301 million, of which Sohu Search received $161 million, Photon received $43 million, and China Web received $97 million.
	On December 2, 2013, Tencent invested $1.5 million in cash in Beijing Sogou Information Service Co., Ltd. (“Sogou Information”), a VIE of Sogou, as additional consideration in connection with the Sogou-Tencent Transactions.
	On March 24, 2014, Sogou purchased from China Web, pursuant to the Repurchase/Put Option Agreement between Sogou and China Web, 14.4 million Series A Preferred Shares of Sogou, for an aggregate purchase price of $47.3 million.
	Pursuant to the Shareholders Agreement, Sohu will hold approximately 53% of the total voting power for the election of the Board of Directors of Sogou, assuming that the remaining repurchase options 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 be available for grants to Sohu management and key employees (the “Sohu Management Sogou 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 is a leading online game developer and operator in China as measured by the popularity of its massively multiplayer online game (“MMOG”) Tian Long Ba Bu (“TLBB”) and its Web games DDTank and Wartune (also known as “Shen Qu”), which Changyou developed in-house. Changyou engages in the development, operation and licensing of online games for PCs and mobile devices. Changyou’s online games include 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, which are played on mobile devices with an Internet connection.
	Basis of Consolidation and Recognition of Noncontrolling Interest
	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, 2013.
	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 three months ended March 31, 2014 are not necessarily indicative of the results expected for the full fiscal year or for any future period.
	Reclassification of Mobile Business to Others Business
	Commencing in the first quarter of 2014, the Group reclassified the mobile business to the others business, because the Group did not consider the mobile business to be significant enough to constitute a separately-disclosed revenue stream. The mobile business offers mobile related services through mobile products to mobile phone users through cooperation with China mobile network operators. The mobile products consist primarily of short messaging services (“SMS”), interactive voice response (“IVR”), ring-back tones (“RBT”), and mobile video. A majority of the content is purchased from third-party content providers. To conform to current period presentations, certain comparative figures for prior periods have been reclassified accordingly. Such reclassifications amounted to $13.8 million for revenues and $9.3 million for costs for the three months ended March 31, 2013.

Segment Information	'
	2	Segment Information
	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 Sohu.com Inc.’s Chief Executive Officer. Some items, such as share-based compensation expense, operating expenses, other income and expense, and income tax expense, are not reviewed by the CODM. These items are disclosed in the segment information for reconciliation purposes only.
	In connection with the reclassification of the mobile business to the others business, as the CODM does not consider mobile to be a significant business that should be separately reviewed, the Group reclassified the mobile segment to the others segment. There are four reportable segments in the Group, consisting of brand advertising, Sogou (which mainly consists of the search and others business), Changyou (which mainly consists of the online game business) and Others. The Group has restated the presentation of its reportable segments for prior periods to conform to the current presentation.

Share-Based Compensation Expense	3 Months Ended

Share-Based Compensation Expense [Abstract]	'
Share-Based Compensation Expense	'
	3	Share-Based Compensation Expense
	Sohu, Changyou, Sogou, and Fox Video Limited (“Sohu Video”) have incentive plans, and prior to June 28, 2013 7Road.com Limited (“7Road”) had an incentive plan, for the granting of share-based awards, including common stock or 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. For Tencent restricted share units that Tencent had granted to employees who transferred to Sogou with the Soso search-related businesses, share-based compensation expense is recognized by Sogou in the consolidated statements of comprehensive income based on the then-current fair value at each reporting date.
	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 March 31, 2014, grants of options for the purchase of 16,368,200 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 March 31, 2014 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 had occurred for purposes of ASC 718 and hence no share-based compensation expense was recognized for the three months ended March 31, 2014.
	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 the 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 initial public offering, which is not considered probable until it occurs, no share-based compensation expense was recognized for the fair value of the original awards. Incremental compensation expense, which is not classified as share-based compensation expense, is equal to the fair values of the two new compensation schemes included in the exchange program as of the date of the modification resulting from 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 months ended March 31, 2014, compensation expense of $0.3 million was recognized in the consolidated statements of comprehensive income. As of March 31, 2014, 7Road paid $2.6 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 the three months ended March 31, 2014, compensation expense of $32,000 was recognized in the consolidated statements of comprehensive income.
	Share-based Compensation Expense Recognition
	Share-based compensation expense was recognized in costs and /or expenses for the three months ended March 31, 2014 and 2013, respectively, as follows (in thousands):

Changyou Employee Incentive Plans	3 Months Ended

Changyou Employee Incentive Plans [Abstract]	'
Changyou Employee Incentive Plans	'
	4	Changyou Employee Incentive Plans
	On February 8, 2014, Changyou’s Board of Directors approved three new employee incentive plans with terms of 10 years, effective January 1, 2014, under which Changyou may pay compensation to employees based on Changyou’s profits, or the profits of specified projects. Eligible employees will receive a cash award from the plans as a bonus based on the number of employee incentive instruments they hold in the plans.
	Under two of these three plans, Changyou may pay compensation to employees based on Changyou’s profits. Changyou will distribute to eligible employees who participate in the plans up to 5% of Changyou’s annual adjusted net profits. Combined, these two plans will distribute up to 10% of Changyou’s annual adjusted net profits. Eligible employees will participate in these plans by paying an amount to purchase instruments that will entitle them, while they are employed by Changyou, to receive annual compensation under the plans. After four years of service to Changyou, employees who participate in either of these two plans will be entitled to sell their instruments to other employees at any time during their employment with Changyou at a price negotiated between the two employees, and by doing so would be compensated with the present value of their expected future cash bonuses for the remaining period of the incentive plans. Management concluded that compensation expense associated with these two plans should be accounted for by analogy to deferred compensation arrangements, and that the present value of the amounts forecasted to be distributed under the plans should be amortized over the first four years after the effective date of the plans, before the instruments are first allowed to be transferred to other employees; that the present value of future cash bonuses in the remaining period should be re-measured at each reporting date; that the gain or loss resulting from the re-measurement in the first four years should be amortized over the remaining portion of the four-year period; and that the gain or loss after the four-year period should be booked immediately. For the three months ended March 31, 2014, compensation expense recognized for these two plans was $1.3 million.
	The third employee incentive plan is structured to allow eligible employees to receive up to 20% of the annual adjusted net profits of projects that they work on. Unlike under the first two plans, certain of the incentive instruments to be issued under this plan will permit participating employees to sell the instruments to other employees at any time during their employment, and certain of the incentive instruments will not permit participating employees to sell their instruments to other employees. Management concluded that compensation expense in the former case should be accounted for by analogy to deferred compensation arrangements, and accordingly should be accrued as of the effective date of the plan at the then present value of the amounts forecasted to be distributed under the plan; that the gain or loss resulting from the re-measurement of the cash bonus in the remaining period of the plan should be booked immediately; and that compensation expense in the latter case should be recognized when the amount of relevant distributions under these plans is determined and Changyou’s obligations are established each year. For the three months ended March 31, 2014, compensation expense recognized for this plan was $25.2 million.

Fair Value Measurements	'
	5	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 March 31, 2014 (in thousands):
						Fair value measurements at reporting date using

	Financial instruments matured /exercised			(81,273	)		(1,584	)
	Ending balance at March 31, 2014		$	0		$	0
	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 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.
	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 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, and funding its acquisitions and its share repurchase program. These bank loans are 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 according to their payment terms.
	As of March 31, 2014, the total amount of the bank loans was $257 million, all of which carried a floating rate of interest based on the London Inter-Bank Offered Rate (“LIBOR”). For the three months ended March 31, 2014 and March 31, 2013, interest income from the restricted time deposits securing the loans was $4.2 million and $2.8 million, respectively, and interest expense on the bank loans was $1.7 million and $1.9 million, respectively.
	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 March 31, 2014, the Sohu Group’s investment in financial instruments was nil. For the three months ended March 31, 2014 and 2013, the Sohu Group recorded in the consolidated statements of comprehensive income change in the fair value of short-term investments in the amount of $16,000 and $0.7 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 six-month periods. The Debtor’s obligations on the debt were secured by a pledge from the Debtor’s parent company of its entire equity interest in the Debtor. The Company extended the maturity of the security, at an interest rate of 6.8% per annum, for successive six-month periods through March 2014. Under the terms of the security, the Company had 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. On March 31, 2014, the Company neither extended the debt security nor exercised the option, and accordingly the $81.3 million (or RMB0.5 billion) principal amount of the security was repaid to the Company on that date.
	For the three months ended March 31, 2014 and 2013, interest income from this debt security amounted to $1.37 million and $1.35 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 months ended March 31, 2014 and 2013, 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 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. On March 24, 2014, Sogou purchased from China Web, pursuant to the Repurchase/Put Option Agreement between Sogou and China Web, 14.4 million Series A Preferred Shares of Sogou, for an aggregate purchase price of $47.3 million.
	Sogou’s repurchase options with Photon and China Web were initially recognized in additional paid-in capital in the Sohu Group’s consolidated balance sheets at fair value when the agreements were signed. Any subsequent changes in the fair values of the repurchase options were not and will not be recognized. On March 24, 2014, the repurchase option with China Web was exercised by Sogou. As of March 31, 2014, the remaining balance for the repurchase option with Photon in additional paid-in capital was $1.2 million, based on the fair value of the repurchase option on September 16, 2013.
	China Web’s put option with Sogou was initially recognized in other short-term liabilities in the Sohu Group’s consolidated balance sheets at fair value when the agreement was signed. Subsequent changes in the fair values of the put option were recognized quarterly in other income /(expense) in the Sohu Group’s consolidated statements of comprehensive income. In the first quarter of 2014, while the put option remained outstanding, the changes in the fair value of the put option of $2.3 million were recognized in other income in the Sohu Group’s consolidated statements of comprehensive income. After Sogou’s repurchase of the Series A Preferred Shares from China Web, the other short-term liabilities recognized with respect to China Web were reversed to zero.
	Management determined the fair values of the repurchase options with Photon and China Web when the agreements were signed, and of the put option with China Web before Sogou exercised the repurchase option, using the binominal model, with a discount for lack of marketability, given that the repurchase options and the put option were not publicly traded at the time of grant. Management made the determination with the assistance of a qualified professional appraiser using management’s estimates and assumptions. The Sohu Group classifies the valuation techniques that use these inputs as Level 3 of fair value measurements.
	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 any changes 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.

Taxation	'
	7	Taxation
	Sohu.com Inc. is subject to United States (“U.S.”) income tax, and Changyou’s income that is from a U.S. source is generally subject to U.S. 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 Group did not have any penalties or significant interest associated with tax positions for the three months ended March 31, 2014, nor did the Group have any significant unrecognized uncertain tax positions for the three months ended March 31, 2014.
	PRC Corporate Income Tax
	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 (“HNTEs”). Under this preferential tax treatment, HNTEs can enjoy an income tax rate of 15% for three years, but need to re-apply after the end of the three-year period. In addition, the CIT Law and its implementing regulations provide that a “Software Enterprise” can enjoy 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 “Key National Software Enterprise” can enjoy a further reduced preferential income tax rate of 10% for two years, but need to re-apply after the end of the two-year period.
	Entities Qualified as HNTEs
	As of March 31, 2014, the following entities were qualified as HNTEs: Beijing Sohu New Era Information Technology Co., Ltd. (“Sohu Era”), Beijing Sohu New Media Information Technology Co., Ltd. (“Sohu Media”), Beijing Sohu Internet Information Service Co., Ltd. (“Sohu Internet”), Beijing Sogou Technology Development Co., Ltd. (“Sogou Technology”), Sogou Information, Changyou’s China-based subsidiary Beijing AmazGame Age Internet Technology Co., Ltd. (“AmazGame”), Changyou’s China-based VIE Beijing Gamease Age Digital Technology Co., Ltd. (“Gamease”), and Shenzhen 7Road Technology Co., Ltd. (“Shenzhen 7Road”).
	Entities Qualified as Software Enterprises
	As of March 31, 2014, the following entities were qualified as Software Enterprises: AmazGame, 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”). AmazGame also qualified as a “Key National Software Enterprise.”
	Applicable Income Tax Rate
	For the three months ended March 31, 2014, Sohu Era, Sohu Media, Sohu Internet, Sogou Technology, Sogou Information, Gamease and Shenzhen7Road were entitled to an income tax rate of 15% as HNTEs. Gamespace and Shanghai ICE were entitled to an income tax rate of 12.5% as Software Enterprises. 7Road Technology was in its second income tax exemption year as a Software Enterprise. AmazGame was entitled to an income tax rate of 10% as a Key National Software Enterprise. ICE Information was not subject to income tax as it has been incurring losses.
	Sohu Era, Sohu Media, Sogou Technology, AmazGame, Gamease and Shenzhen 7Road will need to re-apply for HNTE status at least three months prior to September 2014, Sohu Internet and Sogou Information will need to re-apply for HNTE status in 2015, and AmazGame will need to re-apply for Key National Software Enterprise in 2014.
	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 will remain subject to a withholding tax rate of 10%.
	In order to fund the distribution of a dividend to shareholders of Sohu’s majority-owned subsidiary Changyou, Changyou’s board of directors determined to cause one of its PRC subsidiaries to declare and distribute a cash dividend of all of its 2012 stand alone earnings and half of its 2013 and 2014 stand alone earnings to its direct overseas parent company, Changyou HK. With the exception of that dividend, the Sohu Group does not intend to have any of its PRC subsidiaries distribute any undistributed profits of such subsidiaries to their direct overseas parent companies, but rather intends that such profits will be permanently reinvested by such subsidiaries for their PRC operations.
	PRC Value-Added Tax and Business Tax
	Effective September 1, 2012, a pilot program (the “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. All the Sohu Group’s brand advertising and search revenues as well as certain online game revenues were subject to the Pilot Program.
	VAT payable on advertising and search revenues as well as online game revenues from Changyou’s Web game operations that were not developed in house is the difference between the output VAT (at a rate of 6%) and available input VAT amount (at the rate applicable to the supplier). Other online game revenues were not affected by the Pilot Program. Before and after the Pilot Program, revenues from MMOG operations are subject to a 5% Business Tax, and revenues of 7Road that deemed to be derived from the sale of software are subject to VAT. VAT payable by 7Road is at a rate of 17%, with a 14% immediate tax refund irrespective of the availability of any input VAT, resulting in a net rate of 3%.
	The Group adopted the net presentation method for its brand advertising and search businesses both before and after the implementation of the Pilot Program. The Group adopted the gross presentation method for revenues of 7Road deemed to be derived from the sale of software both 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%.To the extent that it has U.S. taxable income, the Sohu Group accrues U.S. corporate income tax in its consolidated statements of comprehensive income and makes estimated tax payments as and when required by U.S. law.

	Unconditional Obligations
	As of March 31, 2014, the Sohu Group had commitments for bandwidth purchases in the amount of $79.2 million, commitments for operating leases in the amount of $68.3 million, commitments for purchases of games developed by third-parties in the amount of $49.5 million, commitments for video content purchases in the amount of $39.3 million, commitments for purchases of cinema advertisement slot rights in the amount of $29.2 million and commitments for other content and service purchases in the amount of $25.0 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.
	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, 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 10 - VIE.
	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.

	9	Contingent Consideration
	The agreement for Changyou’s acquisition of Beijing Doyo Internet Technology Co., Ltd. (“Doyo”) includes a contingent consideration arrangement that requires additional consideration to be paid by Changyou based on the achievement of specified performance milestones by Doyo for the fiscal years 2013 through 2015. The range of the undiscounted amounts Changyou could pay under the contingent consideration agreement is between nil and $7.3 million. The fair value of the contingent consideration, in the amount of $4.8 million, was recognized on the acquisition date using the income approach /discounted cash flow method with a scenario analysis applied. There were no indemnification assets involved. For the three months ended March 31, 2014, change in the fair value of the contingent consideration was nil.
	The agreement for Changyou’s acquisition of the RaidCall Business includes a contingent consideration arrangement that gives Changyou the right to acquire additional shares of TalkTalk Limited (“TalkTalk”) at no cost if specified conditions occur through the 2014 fiscal year. The range of the additional shares of TalkTalk that Changyou could acquire under the contingent consideration arrangement is between nil and 7.5% of the outstanding shares of TalkTalk on a post-issuance fully-diluted basis. The fair value of the contingent consideration recognized on the acquisition date was nil, as management determined that it is unlikely that the specified conditions will occur and that as a result the fair value and the financial impact on recognition of the noncontrolling interest was zero. For the three months ended March 31, 2014, change in the fair value of the contingent consideration was nil.

VIEs	'
	10	VIE
	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 March 31, 2014, the aggregate amount of these loans was $14.9 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 March 31, 2014, the registered capital and PRC statutory reserves of the consolidated VIEs totaled $56.4 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 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 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.
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 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 Sohu mainly consists of patents, copyrights, trademarks, and domain names. The Group’s operations and businesses may be adversely impacted if the Group loses the ability to use and enjoy assets held by these VIEs.
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 has the power to direct this VIE’s activities that will significantly impact its economic performance nor has the obligation to absorb losses of, or the right to receive benefits from, this VIE that could potentially be significant to 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.

	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 ordinary shares issued pursuant to the exercise of share options and upon vesting and settlement of restricted share units. The 2,000,000 reserved shares became 20,000,000 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 will expire in August 2018.
	Through March 31, 2014, Changyou had granted under the Changyou 2008 Share Incentive Plan 15,000,000 ordinary shares to its chief executive officer Tao Wang, through Prominence Investments Ltd., which is an entity that may deemed under applicable rules of the Securities and Exchange Commission to be beneficially owned by Tao Wang. As of March 31, 2014, Changyou had also granted under the Changyou 2008 Share Incentive Plan restricted share units, settleable upon vesting by the issuance of an aggregate of 4,863,552 ordinary shares, to its executive officers other than Tao Wang, and certain other Changyou employees.
	For the three months ended March 31, 2014 and 2013, total share-based compensation expense recognized for awards under the Changyou 2008 Share Incentive Plan was $0.3 million and $0.2 million, respectively.
	Share-based Awards Granted before Changyou’s Initial Public Offering
	In January and April 2008, before Changyou had completed its initial public offering (“IPO”), Changyou granted Changyou ordinary shares to Tao Wang and restricted share units to its executive officers other than Tao Wang and certain key Changyou employees. All of these ordinary shares and restricted share units had become vested as of the end of 2012; hence there has been no share-based compensation expense recognized with respect to such ordinary shares and restricted share units for periods commencing after December 31, 2012.
	In February 2009, Changyou granted restricted share units to certain other Changyou employees. The fair value of these restricted share units as of the grant date was determined based on Changyou’s offering price for its IPO, which was $8.00 per ordinary share. All of these restricted share units had become vested in the first quarter of 2013; hence there has been no share-based compensation expense recognized for periods after March 31, 2013. For the three months ended March 31, 2014 and 2013, share-based compensation expense recognized for these restricted share units was nil and negative $0.3 million, respectively. The negative $0.3 million resulted from Changyou’s true-up of the shared-based compensation expense for forfeited restricted share units in the first quarter of 2013. The total fair value on their respective vesting dates of these restricted share units that vested during the three months ended March 31, 2014 and 2013 was nil for both periods.
Share-based Awards Granted after Changyou’s Initial Public Offering
Through March 31, 2014, in addition to the share-based awards granted before Changyou’s IPO, Changyou had granted restricted share units, settleable upon vesting with the issuance of an aggregate of 1,667,552 ordinary shares, to certain of its executive officers other than Tao Wang and to certain of its other employees. These restricted share units are subject to vesting over a four-year period commencing on their grant dates. Share-based compensation expense for such restricted share units is recognized on an accelerated basis over the requisite service period. The fair value of restricted share units was determined based on the market price of Changyou’s American depositary shares (“ADSs”) on the grant date.
A summary of activity for these restricted share units as of and for the three months ended March 31, 2014 is presented below:
Restricted Share Units		Number of			Weighted-Average
		Units			Grant-Date
		(in thousands)			Fair Value
Unvested at January 1, 2014			218		$	14.46

Awards of share rights may be granted under the Sogou 2010 Share Incentive Plan to management and employees of Sogou and of any present or future parents or subsidiaries or variable interest entities of Sogou. The maximum term of any share right 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. As of March 31, 2014, Sogou had issued options for the purchase of 35,255,125 ordinary shares under the 2010 Sogou Share Incentive Plan.
Of the 35,255,125 issued share options, 23,025,125 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. Accordingly, for purposes of recognition of share-based compensation expense, each installment is considered to be granted as of that date. As of March 31, 2014, performance targets had been set for 15,748,900 share options, subject to vesting upon service period requirements for management and key employees being met and Sogou’s achievement of performance targets and, accordingly, such options were considered granted for purposes of recognition of share-based compensation expense.

Of the issued share options, 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 IPO of its ordinary shares (“Sogou’s IPO”) and the expiration of all underwriters’ lockup periods applicable to Sogou’s 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 issued share options, for the purchase of 3,960,000 Sogou ordinary shares, 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 after June 15, 2013, all installments of these remaining 3,960,000 share options will cease to vest.
All installments of 8,270,000 share options that are subject to vesting upon completion of Sogou’s IPO and 3,960,000 share options that are subject to vesting upon the completion of an Event were considered granted upon the issuance of the options. The completion of an Event is considered to be a performance condition of the awards. An IPO or other 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 Event, and hence no share-based compensation expense was recognized for the three months ended March 31, 2014 for the 8,270,000 share options that are subject to vesting upon completion of Sogou’s IPO or for 3,960,000 share options that are subject to vesting upon the completion of an Event.
A summary of share option activity under the Sogou 2010 Stock Incentive Plan as of and for the three months ended March 31, 2014 is presented below:
Options		Number			Weighted		Weighted
		Of			Average		Average
		Shares			Exercise		Remaining
		(in thousands)			Price		Contractual
							Life (Years)
Outstanding at January 1, 2014			17,953		$	0.251
Granted			0
Exercised			0
Forfeited or expired			(9	)		0.001
Outstanding at March 31, 2014			17,944			0.251		8.4
Vested at March 31, 2014 and expected to vest thereafter			5,658
Exercisable at March 31, 2014			2,813
For the three months ended March 31, 2014 and 2013, total share-based compensation expense recognized for share options under the Sogou 2010 Share Incentive Plan was $383,000 and $16,000, respectively.
As of March 31, 2014, there was $388,000 of unrecognized compensation expense related to the unvested share options. The expense is expected to be recognized over a weighted average period of 0.25 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:
Granted to Employees		2014
Average risk-free interest rate		2.10%~2.87%
Exercise multiple		2~3
Expected forfeiture rate (Post-vesting)		1.3%~6.0%
Weighted average expected option life		10
Volatility rate		47.00%~49.00%
Dividend yield		0%
Fair value		0.67
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 March 31, 2014 and 6.0% for Sogou employees’ share options granted as of March 31, 2014. 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 Sohu Management Sogou Share Option Arrangement, which was approved by the boards 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 March 31, 2014, Sohu had issued options for the purchase of 10,776,000 Sogou ordinary shares to Sohu management and key employees under the Sohu Management Sogou Share Option Arrangement.
Of the 10,776,000 issued share options, 8,376,000 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. Accordingly, for purposes of recognition of share-based compensation expense, each installment is considered to be granted as of that date. As of March 31, 2014, performance targets had been set for 6,585,750 share options vesting upon service period requirements for management and key employees being met and Sogou’s achievement of performance targets and, accordingly, such share options were considered granted. As of March 31, 2014, 5,845,625 share options had become vested and exercisable because both the service period and the performance requirements had been met, and 5,105,500 of the vested share options 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 months ended March 31, 2014 for these 2,400,000 share options.
A summary of share option activity as of and for the three months ended March 31, 2014 is presented below:
Options		Number			Weighted		Weighted
		Of			Average		Average
		Shares			Exercise		Remaining
		(in thousands)			Price		Contractual
							Life (Years)
Outstanding at January 1, 2014			3,880		$	0.625
Granted			0
Exercised			0
Forfeited or expired			0
Outstanding at March 31, 2014			3,880			0.625		8.24
Vested at March 31, 2014			1,477
Exercisable at March 31, 2014			740
For the three months ended March 31, 2014 and 2013, total share-based compensation expense recognized for share options under the Sohu Management Sogou Share Option Arrangement was $50,000 and nil, respectively.
As of March 31, 2014, there was $50,000 of unrecognized compensation expense related to the unvested share options. The expense is expected to be recognized over a weighted average period of 0.25 years.
The method used to determine the fair value of share options granted to Sohu management and key employees was the same as the method used for the share options granted to Sogou’s management and key employees as described above, except for the assumptions used in the BP Model as presented below:
Granted to Employees		2014
Average risk-free interest rate		2.10%~2.87%
Exercise multiple		2~3
Expected forfeiture rate (Post-vesting)		0%-8%
Weighted average expected option life		10
Volatility rate		47.00%-48.00%
Dividend yield		0%
Fair value		0.27-0.38
Option Modification
In the first and second quarter of 2013, a portion of the 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 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 share options, the modification was not considered substantive. Accordingly, 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 March 31, 2014, 19,245,000 share options granted under the Sogou 2010 Share Incentive Plan and 1,225,000 share options granted under the Sohu Management Sogou Share Option Arrangement, or a total of 20,470,000 share options, had been exercised early.
Tencent Share-based Awards Issued to Employees Who Transferred to Sogou with Soso Search-related Businesses
Certain persons who became Sogou employees when Tencent’s Soso 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 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, which 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.
As of March 31, 2014, unvested Tencent restricted share unit awards held by these employees provided for the issuance of up to 145,644 ordinary shares of Tencent. Share-based compensation expense of $1.8 million related to these Tencent restricted share units was recognized in the Group’s consolidated statements of comprehensive income for the three months ended March 31, 2014. As of March 31, 2014, there was $5.9 million of unrecognized compensation expense related to these unvested restricted share units. This amount is expected to be recognized over a weighted average period of 3.01 years.

	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 Investments Limited (“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 the aggregate amount of $301 million, of which Sohu Search received $161 million, Photon received $43 million, and China Web received $97 million. On December 2, 2013, Tencent invested $1.5 million in cash in Sogou’s VIE Sogou Information, as additional consideration for the Sogou-Tencent Transactions, in return for a 45% equity interest in Sogou Information. Through a share pledge agreement and an exclusive equity interest purchase right agreement between Tencent and Sogou Technology, and similar agreements between the other two shareholders of Sogou Information, Sogou Technology controls all shareholder voting rights in Sogou Information, has the power to direct the activities of Sogou Information, and is the primary beneficiary of Sogou Information, and Tencent and the other two shareholders of Sogou Information act as Sohu Technology’s nominees.
	On March 24, 2014, Sogou purchased from China Web, pursuant to the Repurchase/Put Option Agreement between Sogou and China Web, 14.4 million Series A Preferred Shares of Sogou, for an aggregate purchase price of $47.3 million.
	As of March 31, 2014, Sogou had outstanding a combined total of 356,371,908 ordinary shares and preferred 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 from Sohu 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)	Tencent:
	6,757,875 Class A Ordinary Shares, 65,431,579 Series B Preferred Shares and 79,368,421 non-voting Class B Ordinary Shares; and
	(iv)	Various employees of Sogou and Sohu: 8,306,283 Class A Ordinary Shares.
	Since Sohu controls the election of the Board of Directors of Sogou, Sohu is Sogou’s controlling shareholder. Therefore, 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.
	Because no ordinary shares will be issued with respect to share options granted by Sogou until they are vested and exercised, 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 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 /(Loss) per Share.
	Terms of Sogou Preferred Shares
	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 “Sogou 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 Sogou 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 Sogou Preferred Shares are not redeemable at the option of the holders.
	Conversion Rights
	Each Sogou Preferred Share is convertible, at the option of the holder, at any time, and without the payment of additional consideration by the holder. Each Sogou 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 Sogou 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 Sogou 2010 Share Incentive Plan. Each Sogou 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 Sogou Preferred Share, which is currently one-for-one for both Series A Preferred Shares and Series B Preferred Shares.
	Voting Rights
	Each holder of Sogou Preferred Shares is entitled to cast the number of votes equal to the number of Class A Ordinary Shares into which the Sogou Preferred Shares held by such holder are then convertible.
	Other Rights
	The holders of Sogou Preferred Shares have various other rights typical of preferred share investments.
	Terms of Sogou Class A Ordinary Shares and Class B Ordinary Shares
	The Class A Ordinary Shares and Class B Ordinary Shares have identical rights, 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.
	Changyou Share Repurchase Transactions
	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. During the three months ended March 31, 2014, Changyou did not repurchase any of its ADSs under the share repurchase program.

Mezzanine Equity [Abstract]	'
Mezzanine Equity	'
	13	Mezzanine Equity
	Mezzanine Equity consisted of noncontrolling interest in 7Road and a put option pursuant to which the noncontrolling shareholders would have had the right to put their ordinary shares in 7Road to Changyou at a pre-determined price if 7Road achieved specified performance milestones before the expiration of the put option and 7Road did not complete an IPO on NASDAQ, the New York Stock Exchange (the “NYSE”) or the Stock Exchange of Hong Kong (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 calculated, 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 was 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.
	For the three months ended March 31, 2014 and 2013, accretion charges of nil and $10.7 million, respectively, 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/(loss) 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
	Since Sohu controls the election of the Board of Directors of Sogou, Sohu is Sogou’s controlling shareholder. Therefore, 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’ investments in Sogou Preferred Shares and 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, and on the terms of the classes of Sogou shares held, by the noncontrolling shareholders in Sogou.
	By virtue of these terms, Sogou’s 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.
	Net income from Sogou has been, and future 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 March 31, 2014 and December 31, 2013, noncontrolling interest in the consolidated balance sheets was $455.1 million and $510.0 million, respectively.

	Noncontrolling Interest of Changyou
	As of March 31, 2014 and December 31, 2013, noncontrolling interest of Changyou of $297.8 million and $307.9 million, respectively, was recognized in the Sohu Group’s consolidated balance sheets, representing a 32% economic interest as of both March 31, 2014 and December 31, 2013 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 March 31, 2014 and December 31, 2013, noncontrolling interest of Sogou of $154.6 million and $199.1 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 Preferred Shares and Ordinary Shares of Sogou, 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, and the repurchase of Sogou Series A Preferred Shares from China Web on March 24, 2014.
	Noncontrolling Interest in the Consolidated Statements of Comprehensive Income
	For the three months ended March 31, 2014 and 2013, $4.9 million net loss and $23.1 million net income, respectively, attributable to the noncontrolling interest was recognized in the Sohu Group’s consolidated statements of comprehensive income.

	Noncontrolling Interest of Sogou
	For the three months ended March 31, 2014 and 2013, $1.1 million net income and $1.9 million net loss, respectively, attributable to the noncontrolling interest of Sogou was recognized in the Sohu Group’s consolidated statements of comprehensive income, representing Sogou’s net income /(loss) attributable to shareholders other than Sohu.

Net Income /(loss) per Share	'
	15	Net Income /(Loss) per Share
	Basic net income /(loss) per share is computed using the weighted average number of common shares outstanding during the period. Diluted net income /(loss) 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 /(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 three months ended March 31, 2014, 148,000 potential common shares 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 the Sohu Group is adjusted as follows. The adjustment will not be made if there is an anti-dilutive effect.
	-1	Changyou’s net income /(loss) 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, 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 the Sohu Group’s diluted net income /(loss) per share, assuming a dilutive effect, 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. As a result, Changyou’s net income /(loss) attributable to the Sohu Group on a diluted basis decreased accordingly. The effect of this calculation is presented as “incremental dilution from Changyou” in the table below.
	In the first quarter of 2014, all of these Changyou restricted share units would have had an anti-dilutive effect, and were excluded from the calculation of the Sohu Group’s diluted net loss per share. As a result, Changyou’s net operating loss attributable to the Sohu Group on a diluted basis equals the net operating loss used for the calculation of the Sohu Group’s basic net loss per share, and the “incremental dilution from Changyou” in the table below was nil.
	-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 Preferred Shares and 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 is not determined by allocating Sogou’s net income /(loss) to the Sohu Group using the methodology for the calculation of net income /(loss) attributable to the Sogou noncontrolling shareholders discussed in Note 14 - Noncontrolling Interest.
	In the calculation of the Sohu Group’s diluted net income /(loss) per share, assuming a dilutive effect, the percentage of the Sohu Group’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 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 effect of this calculation is presented as “incremental dilution from Sogou” in the table below.
	In the first quarter of 2014, all of these Sogou shares and share options would have had an anti-dilutive effect, and were excluded from the calculation of the Sohu Group’s diluted net loss per share. As a result, Sogou’s net income attributable to the Sohu Group on a diluted basis equals the net income used for the calculation of the Sohu Group’s basic net loss per share, and the “incremental dilution from Sogou” in the table below was nil.
	As discussed in Note 1 - Organization and Nature of Operations, on March 24, 2014 Sogou purchased from China Web 14.4 million Series A Preferred Shares of Sogou for an aggregate purchase price of $47.3 million. The transaction gave rise to a deemed dividend amounting to $27.7 million, which was deemed to have been contributed by Sohu, as a holder of ordinary shares of Sogou, for the difference between the price Sogou paid to China Web for the Series A Preferred Shares and the carrying amount of these 14.4 million Series A Preferred Shares in the Group’s consolidated financial statements. This deemed dividend has been subtracted from net income attributable to Sohu.com Inc. for the three months ended March 31, 2014 in the table below when calculating the basic and diluted net loss per share attributable to Sohu.com Inc.
	The following table presents the calculation of the Sohu Group’s basic and diluted net income /(loss) per share (in thousands, except per share data).

	The FASB issued Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity, which changes the threshold for reporting discontinued operations and adds new disclosures. The new guidance defines a discontinued operation as a disposal that “represents a strategic shift that has (or will have) a major effect on an entity’s operations and financial results.” The standard is required to be adopted by public business entities in annual periods beginning on or after December 15, 2014, and interim periods within those annual periods. Entities may “early adopt” the guidance for new disposals. The Group is currently evaluating the impact on its consolidated financial statements of adopting this guidance.
