[1]	Deferred income tax assets are evaluated on the basis of each operating entity. For any entities in loss in the year of 2013, the Group took full allowance against the net deferred tax assets. For entities in profit in the year of 2013, the Group assesses the likelihood that the Group will recover the deferred tax assets from future taxable income. The total current deferred income tax assets were resulted from deductible advertising expenses, bad debt provision, government subsidy, accruals, accrued but unpaid payrolls and fixed asset depreciation from entities in profit in 2013.
[2]	Balances are presented using period-end exchange rate of RMB against USD of year 2013.
[3]	All of the VIEs' assets can be used to settle obligations of their primary beneficiary. Liabilities recognized as a result of consolidating these VIEs do not represent additional claims on the Company's general assets (Note 1(d)).

[1]	Since Class A common shares and Class B common shares share identical characteristics (Note 19), only one EPS is presented for both classes. 6,735,642 common shares resulting from the assumed conversions of 4% Convertible Senior Notes (Note 17) were excluded from the calculation of diluted net (loss)/earnings per share for the year ended December 31, 2013, as their effect is anti-dilutive.
[2]	Each ADS represents five Class A common shares. The net (loss) / earnings per ADS for the year ended December 31, 2011, 2012 and 2013 were calculated using the same conversion ratio assuming the ADSs existed during these periods.

Principal Activities and Organization	12 Months Ended

PRINCIPAL ACTIVITIES AND ORGANIZATION [Abstract]	'
Principal Activities and Organization	'
	1. PRINCIPAL ACTIVITIES AND ORGANIZATION
	(a) Principal activities
	NQ Mobile Inc. (“NQ Mobile”, or the “Company”), through its subsidiaries, its variable interest entities (“VIEs”), and the VIEs’ subsidiaries, is principally engaged in the provision of mobile Internet services in the People’s Republic of China (the “PRC” or “China”) and overseas markets. NQ Mobile’s service portfolio includes mobile security, productivity and privacy protection, mobile games as well as interest-based mobile community applications (e.g. gadget, healthcare and etc.) and advertising for the consumer market and an entire mobility solution set for the enterprise market. The Company, its subsidiaries, its VIEs and the VIEs’ subsidiaries are hereinafter collectively referred to as the “Group”.
	(b) Reorganization
	The Company was incorporated as a limited liability company under the laws of the Cayman Islands (“Cayman”) on March 14, 2007. The Company was 100% owned by RPL Holdings Limited (“RPL”). RPL is a limited liability company organized under the laws of British Virgin Islands (“BVI”), which is owned and controlled by Dr. Henry Yu Lin, Dr. Vincent Wenyong Shi, and Mr. Xu Zhou (collectively, the “Founders”).
	In May 2007, the Company established NQ Mobile (Beijing) Co., Ltd. (“NQ Beijing” or “WFOE”) as a wholly foreign-owned enterprise in the PRC. In June 2007, the Company undertook a reorganization (the “Reorganization”) to become the ultimate holding company of the Group. Prior to the Reorganization, the Group’s business was operated by Beijing NQ Technology Co. Ltd. (“Beijing Technology”), a company wholly owned and controlled by the Founders, which commenced operations on October 21, 2005. By entering into a series of agreements (collectively, “VIE Agreements”) with the Founders and NQ Beijing, Beijing Technology became a variable interest entity whose primary beneficiary is NQ Beijing. Consequently, the Company as the parent of NQ Beijing became the ultimate primary beneficiary of Beijing Technology and has consolidated financial statements of Beijing Technology and its subsidiaries. Beijing Technology was the predecessor of the Group and operated all of the business of the Group prior to the Reorganization.
	Immediately before the Reorganization, Beijing Technology was 100% owned by the Founders and the ultimate owners’ shareholdings of the Beijing Technology were identical to those of the Company. There was no change in ownership of Beijing Technology immediately before and after the Reorganization. Accordingly, the Reorganization is accounted for as a legal reorganization of entities under common control in a manner similar to a pooling-of-interest.
	(c) Subsidiaries, VIEs and VIEs’ subsidiaries

	(d) Variable Interest Entity
	Basic Information
	PRC laws and regulations prohibit or restrict foreign ownership of companies from providing mobile value added services in the PRC where certain licenses are required for the provision of such services. To comply with these PRC laws and regulations, the Company provides services subject to such restrictions through Beijing Technology and its subsidiaries in China. To provide the Company the expected residual returns of the VIE and its subsidiaries, NQ Beijing entered into a series of contractual arrangements with Beijing Technology and its registered shareholders to enable the Company, through NQ Beijing to:
		•		exercise effective control over the VIE;
		•		receive substantially all of the economic benefits and residual returns, and absorb substantially all the risks of expected losses from the VIE as if they were their sole shareholders; and
		•		have an exclusive option to purchase all of the equity interests in the VIE.
	In September 2013, the Company completed the acquisition of Best Partner and its subsidiaries, which primarily engage in advertising activities based on mobile-advertising platform in the PRC and are also subjected to restrictions from PRC laws and regulations for providing internet content services. Effective upon acquisition of Best Partner by NQ Mobile, Wanpu Century becomes the VIE of Wanpu Beijing, of which 100% equity interest was owned by the Company through Best Partner. See Note 4 – “Business Combination”. Through a series of contractual agreements among Wanpu Beijing, Wanpu Century, and the shareholders of Wanpu Century, the Group has effective control over its VIE, receive substantially all of the economic benefits and absorb substantially all of the risks of the VIE, and have an exclusive option to purchase all of the equity interests in the VIE through Wanpu Beijing.
	The Group has adopted the guidance of accounting for variable interest entities, which requires certain variable interest entities to be consolidated by the primary beneficiary of the entities. The Company’s management evaluated the relationships among the Company, NQ Beijing and Beijing Technology, as well as the relationships among the Company, Wanpu Beijing, and Wanpu Century, and the economic benefits flow of the applicable contractual arrangements. The Group concluded that NQ Beijing is the primary beneficiary of Beijing Technology, and Wanpu Beijing is the primary beneficiary of Wanpu Century. As a result, the results of operations, assets and liabilities of these VIEs and their subsidiaries have been included in the Company’s consolidated financial statements.
	Summary of significant agreements current in effect
	Exclusive Technical Consulting Services Agreement between NQ Beijing and Beijing Technology. Under the exclusive technical consulting services agreement, NQ Beijing has the exclusive right to provide to Beijing Technology the technical consulting services related to Beijing Technology’s business operation.

All the other terms remain the same as the original agreements.
	Risks in Relation to the VIE Structure
	It is possible that the Company’s conduct 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 businesses would have broad discretion in dealing with such a violation, including levying fines, confiscating the Company’s income, revoking the business or operating licenses of the affected businesses, requiring the Company to restructure its ownership structure or operations, or requiring the Company to discontinue all or any portion of its operations. Any of these actions could cause significant disruption to the Company’s business operations, and have a material adverse impact on the Company’s cash flows, financial position and operating performance. The Company’s management considers the possibility of such a finding by PRC regulatory authorities to be remote.
	In addition, it is possible that the agreements among WFOEs, VIEs and shareholders of the VIEs would not be enforceable in China if PRC government authorities or courts were to find that such agreements contravene PRC laws and regulations or are otherwise not enforceable for public policy reasons. In the event that the Company was unable to enforce these agreements, the Company would not be able to exert effective control over the affected VIEs. Consequently, the results of operations, assets and liabilities of the VIEs and its subsidiaries would not be included in the Company’s consolidated financial statements. If such were the case, the Company’s cash flows, financial position and operating performance would be materially adversely affected. The Company’s agreements with respect to its consolidated VIE are approved and in place. The Company’s management believes that such agreements are enforceable, and considers the possibility remote that PRC regulatory authorities with jurisdiction over the Company’s operations and contractual relationships would find the agreements to be unenforceable.

The VIEs contributed an aggregate of 57%, 59% and 71% of the consolidated revenues for the year ended December 31, 2011, 2012 and 2013, respectively. As of December 31, 2012 and 2013, the VIEs accounted for an aggregate of 75% and 50%, respectively, of the consolidated total assets, and 75% and 26%, respectively, of the consolidated total liabilities. The consolidated assets of VIEs mainly comprised of recognized and unrecognized revenue-producing assets. The recognized revenue-producing assets include goodwill and intangible assets acquired through business acquisitions, purchased servers and office facilities. The balances of these assets as of December 31, 2013 were included in the line of “Total non-current assets” in the table above. The unrecognized revenue-producing assets mainly consist of intellectual property, which had no recorded value.
Goodwill primarily represents the expected synergies from combining the acquired business with the business of the Company. Intangible assets acquired through business acquisition are comprised of customer relationships, non-compete agreements, revenue sharing agreements, user base, technologies and games. Please refer to Note 4 – “Business Combination” for goodwill and intangible assets acquired through business combination.
For intellectual property, as of December 31, 2013, the VIEs and their subsidiaries have developed 174 patent registrations and applications, including but not limited to patents covering anti-virus, anti-spam firewall, anti-phishing, contact management, agenda management and parental controls, with respect to consumer mobile security services. Some of these patents have been granted and are currently held by the VIEs, while others are still in the process of being registered. In addition, the VIEs hold 107 copyrights. Moreover, the VIEs have made 10 trademark registrations and approximately 88 registered domain names.
The VIEs’ business operations rely in part on the techniques covered by the following patents to generate revenues: (1) a patent on a method and system to subscribe, configure and move mobile telephone software service conveniently, which was filed in China in September 2007 and has a corresponding U.S. patent application file in May 2010, both of which were granted; and (2) a patent on a method and system for a self-learning intellectualized short message firewall for mobile terminals, which was filed in China in December 2009 and has a corresponding PCT application file in December 2010. (3) a patent on a method and system for anti-theft for mobile terminals, which was filed in China in December 2012 and has a corresponding PCT application in March 2013. (4) a patent on a method and system to show contents on mobile terminals, which was filed in China in October 2013. The last patent application is still pending and undergoing examination by the State Intellectual Property Office of the PRC, or SIPO and USPTO. According to Article 42 of China’s Patent Law, each of the Company’s granted patent rights for invention would have a term of twenty years, starting from its application date.
All intercompany transactions and balances were eliminated upon consolidation.
In accordance with the VIE agreements, the Company has power to direct activities of the VIEs and their subsidiaries, and can have assets transferred out of the VIEs and their subsidiaries without any restrictions. Therefore, the Company considers that there is no asset in the consolidated VIEs and their subsidiaries that can be used only to settle obligations of the consolidated VIEs except for registered capitals of US$7,744 and PRC statutory reserves of US$ 2,082, of their VIEs and VIEs’ subsidiaries, as of December 31, 2013. As the VIEs and their subsidiaries are incorporated as limited liability companies under the PRC Company Law, and as such the creditors of liabilities of these PRC incorporated VIEs have recourse only to the assets of these entities. Accordingly, the creditors of all the liabilities of the Company’s consolidated VIEs do not have recourse to the Company’s general credit.
Currently, there is no contractual arrangement that could require the Company to provide additional financial support to the VIEs. As the Company is conducting mobile value added services, enterprise mobility, advertising business and other services through the VIEs and their subsidiaries in the PRC, the Company may provide such support on a discretional basis in the future, which could expose the Company to a loss.
There is no VIEs where the Company has variable interests but is not the primary beneficiary.

SIGNIFICANT ACCOUNTING POLICIES [Abstract]	'
Significant Accounting Policies	'
	2. SIGNIFICANT ACCOUNTING POLICIES
	(a) Basis of presentation and consolidation
	The accompanying consolidated financial statements include the financial statements of the Company, its subsidiaries, its VIE for which the Company is the ultimate primary beneficiary, and the VIE’s subsidiaries.
	These consolidated financial statements have been prepared on a historical cost basis to reflect the financial position and results of operations of the Company, its subsidiaries, VIEs and VIEs’ subsidiaries in accordance with the accounting principles generally accepted in the United States of America (“US GAAP”).
	Commencing January 1, 2013, due to the expansion of the Company’s business and diversification of revenue streams in 2013, revenue presentation was reclassified into categories of (i) mobile value added services, which includes original revenue stream of consumer mobile security and mobile games; (ii) enterprise mobility; (iii) advertising services; and (iv) other services. The comparative figures, for the years ended December 31, 2011 and 2012, have been reclassified to conform to the current presentation.
	Subsidiaries are those entities in which the Company, directly or indirectly, controls more than one half of the voting power; or has the power to govern the financial and operating policies, to appoint or remove the majority of the members of the board of directors, or to cast a majority of votes at the meeting of directors.
	A VIE is an entity in which the Company, or its subsidiary, through contractual arrangements, bears the risks of, and enjoys the rewards normally associated with, ownership of the entity, and therefore, the Company or its subsidiary is the primary beneficiary of the entity.
	All significant inter-company transactions and balances have been eliminated upon consolidation.
	(b) Business Combinations
	The Company accounts for its business combinations using the purchase method of accounting in accordance with ASC 805: Business Combinations. The purchase method accounting requires that the consideration transferred to be allocated to the assets, including separately identifiable assets and liabilities the Company acquired based on their estimated fair values. The consideration transferred of an acquisition is measured as the aggregate of the fair values at the date of exchange of the assets given, liabilities incurred, and equity instruments issued as well as the contingent considerations and all contractual contingencies as of the acquisition date. The costs directly attributable to the acquisition are expensed as incurred. Identifiable assets, liabilities and contingent liabilities acquired or assumed are measured separately at their fair value as of the acquisition date, irrespective of the extent of any non-controlling interests. The excess of (i) the total of cost of acquisition, fair value of the non-controlling interests and acquisition date fair value of any previously held equity interest in the acquiree over (ii) the fair value of the identifiable net assets of the acquiree, is recorded as goodwill. If the cost of acquisition is less than the fair value of the net assets of the subsidiary acquired, the difference is recognized directly in the consolidated statements of comprehensive income.
	The determination and allocation of fair values to the identifiable assets acquired, liabilities assumed and non-controlling interests is based on various assumptions and valuation methodologies requiring considerable management judgment. The most significant variables in these valuations are discount rates, terminal values, the number of years on which to base the cash flow projections, as well as the assumptions and estimates used to determine the cash inflows and outflows. The Company determines discount rates to be used based on the risks inherent in the related activity’s current business model and industry comparisons. Terminal values are based on the expected life of assets, forecasted life cycle and forecasted cash flows over that period.
	In a business combination achieved in stages, the Company re-measures its previously held equity interest in the acquiree at its acquisition-date fair value and recognizes the resulting gain or loss in earnings.
	(c) Use of estimates
	The preparation of these consolidated financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses and the related disclosures of contingent assets and liabilities. Management makes its estimates based on historical experience and on various other assumptions it believes to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities. Actual results could differ from those estimates. Significant accounting estimates reflected in the Company’s consolidated financial statements mainly include the allowance for doubtful accounts, the valuation allowance of deferred tax assets, the estimated useful lives of long-lived assets, the impairment assessment of long-lived assets and equity investments, the valuation and recognition of share-based compensation, and goodwill and fair value of identifiable assets and liabilities acquired through business combination.
	(d) Cash and cash equivalents
	Cash and cash equivalents represent cash on hand, demand deposits, and other short-term highly liquid investments placed with banks, which have original maturities of three months or less and are readily convertible to known amounts of cash.
	(e) Term deposits
	Term deposits represent time deposits placed with banks with original maturities of more than three months and equal or less than one year. Interest earned is recorded as interest income in the consolidated statements of comprehensive income during the period.
	(f) Short-term investments
	Short term investments refer to the available-for-sale investments made in financial instruments with guaranteed return of principal upon maturity with a variable interest rate indexed to the performance of underlying assets.
	In accordance with ASC 825, for investments in financial instruments with a variable interest rate indexed to the performance of underlying assets, the Company elected the fair value method at the date of initial recognition and carried these investments subsequently at fair value. Changes in the fair value are reflected in the consolidated statements of comprehensive income. The carrying amount of investments approximates their fair value. To estimate fair value, the Company refers to the quoted rate of return provided by banks at the end of each period using discounted cash flow method. The Company classifies the valuation techniques that use these inputs as Level 2 of fair value measurements. Since the Group did not intend to hold the financial instruments over one year, they were classified as short-term investments.
	(g) Allowance for doubtful accounts
	An allowance for doubtful accounts is recorded in the period in which a loss is determined to be probable based on an assessment of specific evidence indicating doubtful collection, historical experience, account balance aging and prevailing economic conditions. Accounts receivable balances are written off after all collection efforts have been exhausted and the potential for recovery is considered remote. The following table presents movement of the allowance for doubtful accounts:
		Balance at		Charged to		Write-Offs			Balance
		Beginning		Expenses		Net of			at End
		of Year				Recoveries			of Year
		US$		US$		US$			US$
	Allowance for doubtful accounts
	2011		315		321		—			636
	2012		636		459		—			1,095
	2013		1,095		3,027		(204	)		3,918
	(h) Inventory
	Inventories, consisting of products and devices available for sale, are accounted for using first in first out method, and are valued at the lower of cost or market. This valuation requires the Company to make judgments, based on currently available information, about the likely method of disposition, such as through sales to individual customers, returns to product vendors, or liquidations, and expected recoverable values of each disposition category.
	(i) Equity investments
	The Company’s equity investments are comprised of privately-held companies and limited partnerships. The Company uses the cost method to account for investments in shares that are not common stock or in-substance common stock, or investments in shares that are common stock or in-substance common stock, but over which the Company does not have significant influence. The Company uses the equity method to account for common stock equivalent equity investments in private-held companies over which the Company has significant influence but does not own a majority equity interest or otherwise control. The Company also uses the equity method to account for investments in limited partnerships unless the Company’s equity interest is so minor that the Company may have virtually no influence over the partnerships operating and financial policies.
	Cost method investments
	In accordance with ASC subtopic 325-20 (“ASC 325-20”), Investments-Other: Cost Method Investments, the Company carries the cost method investments at cost and only adjusts for other-than-temporary declines in fair value and distributions of earnings. Management regularly evaluates the impairment of the cost method investments based on performance and financial position of the investee as well as other evidence of market value. Such evaluation includes, but is not limited to, reviewing the investee’s cash position, recent financing, projected and historical financial performance, cash flow forecasts and financing needs. An impairment loss is recognized in the consolidated statements of comprehensive income equal to the excess of the investment’s cost over its fair value at the balance sheet date of the reporting period for which the assessment is made. The fair value would then become the new cost basis of investment.
	Equity method investments
	In accordance with ASC subtopic 323-10 (“ASC 323-10”), Investments-Equity Method and Joint Ventures: Overall, the Company initially records its equity method investments at cost and any excess of the cost of the investment over the proportional fair value of the underlying tangible and intangible assets and liabilities of the investee is recognized as equity method goodwill, which is included in the equity method investment on the consolidated balance sheets. The Company subsequently adjusts the carrying amount of the investment to recognize the Company’s proportionate share of each equity investee’s net income or loss into consolidated statements of comprehensive income after the date of acquisition. The Company will discontinue applying equity method if an investment (and additional financial supports to the investee, if any) has been reduced to zero.
	Sales of equity interests of an investee by the company is accounted for as gains or losses equal to the difference at the time of sale between selling price and carrying amount of the equity interests sold.
	Impairment for equity investments
	The Group assesses its equity investments for other-than-temporary impairment by considering factors including, but not limited to, current economic and market conditions, operating performance of the companies, including current earnings trends and undiscounted cash flows, and other company-specific information. The fair value determination, particularly for investments in privately-held companies, requires significant judgment to determine appropriate estimates and assumptions. Changes in these estimates and assumptions could affect the calculation of the fair value of the investments and determination of whether any identified impairment is other-than-temporary.
	(j) Property and equipment, net
	Property and equipment are stated at cost less accumulated depreciation and impairment. Depreciation is provided on a straight-line basis over the following estimated useful lives:
		Estimated useful lives of the assets
	Computer equipment		3 years
	Leasehold improvements		Shorter of lease terms and estimated useful lives
	Electronic equipment		3 years
	Office equipment		5 years
	Motor vehicles		5 years
	Expenditure for repairs and maintenance is expensed as incurred. The gain or loss on disposal of property and equipment is the difference between the net sales proceeds and the carrying amount of the relevant assets and is recognized in the consolidated statements of comprehensive income.
	(k) Goodwill
	Goodwill is the excess of the consideration transferred over the fair value of the acquired assets and assumed liabilities in a business combination.
	The Company tests goodwill for impairment at the reporting unit level on an annual basis as of December 31, and between annual tests when an event occurs or circumstances change that could indicate that the asset might be impaired. Commencing in September 2011, in accordance with the FASB revised guidance on “Testing of Goodwill for Impairment,” a company first has the option to assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If the company decides, as a result of its qualitative assessment, that it is more-likely-than- not that the fair value of a reporting unit is less than its carrying amount, the quantitative impairment test is mandatory. Otherwise, no further testing is required. The quantitative impairment test consists of a two-step goodwill impairment test. The first step compares the fair value of each reporting unit to its carrying amount. If the fair value of each reporting unit exceeds its carrying amount, goodwill is not considered to be impaired and the second step will not be required. If the carrying amount of a reporting unit exceeds its fair value, the second step compares the implied fair value of goodwill to the carrying value of a reporting unit’s goodwill. The implied fair value of goodwill is determined in a manner similar to accounting for a business combination with the allocation of the assessed fair value determined in the first step to the assets and liabilities of the reporting unit. The excess of the fair value of the reporting unit over the amounts assigned to the assets and liabilities is the implied fair value of goodwill. This allocation process is only performed for purposes of evaluating goodwill impairment and does not result in an entry to adjust the value of any assets or liabilities. An impairment loss is recognized for any excess in the carrying value of goodwill over the implied fair value of goodwill.
	Application of a goodwill impairment test requires significant management judgment, including the identification of reporting units, assigning assets and liabilities to reporting units, assigning goodwill to reporting units, and determining the fair value of each reporting unit. The judgment in estimating the fair value of reporting units includes estimating future cash flows, determining appropriate discount rates and making other assumptions. Changes in these estimates and assumptions could materially affect the determination of fair value for each reporting unit.
	(l) Intangible Assets
	Intangible assets, comprising computer software, domain name use right, revenue sharing agreements, customer relationship, non-compete agreements, user base, technology, game and other finite-lived intangible assets, which are separable from the fixed assets, are stated at cost less accumulated amortization. Amortization is computed using the straight-line method over the estimated useful lives of the assets.
	(m) Impairment of long-lived assets
	The carrying amounts of long-lived assets other than goodwill are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is evaluated by a comparison of the carrying amount of assets to future undiscounted net cash flows expected to be generated by the assets. Such assets are considered to be impaired if the sum of the expected undiscounted cash flow is less than carrying amount of the assets. The impairment to be recognized is measured by the amount by which the carrying amounts of the assets exceed the fair value of the assets. No impairment of long-lived assets was recognized for any of the periods presented.
	(n) Convertible Debts
	In accordance with ASC subtopic 470-20, the convertible debts are initially carried at the principal amount of the convertible debts, adjusted by the fair value of any embedded put or call option. Debt premium or discounts, which are the differences between the carrying value and the principal amount of convertible debts at the issuance date, together with related debts issuance cost, are subsequently amortized using effective interest method as adjustments to interest expense from the debt issuance date to its first redemption date. Convertible debts are classified as a current liability if they are or will be callable by the Company or puttable by the debt holders within one year from the balance sheet date, even though liquidation may not be expected within that period.
	(o) Functional currency and foreign currency translation
	The Group’s reporting currency is the U.S. dollar (“US$”). The functional currency of the Company, NQ HK and NQ US is US$, while the functional currency of the Company’s PRC subsidiaries, VIE and VIE’s subsidiaries is RMB. In the consolidated financial statements, the financial information of the Company’s subsidiaries, VIE and VIE’s subsidiaries has been translated into US$. Assets and liabilities are translated at the exchange rates on the balance sheet date, equity amounts are translated at historical exchange rates, and revenues, expenses, gains and losses are translated using the average rate for the year. Translation adjustments are reported as foreign currency translation adjustments and are shown as a separate component of other comprehensive income or loss in the statements of shareholders’ equity and comprehensive income.
Transactions denominated in currencies other than the functional currency are translated into prevailing functional currency at the exchange rates prevailing at the dates of the transactions. Monetary assets and liabilities denominated in foreign currencies are translated into the functional currency using the applicable exchange rates at the balance sheet dates. The resulting exchange differences are included in the consolidated statements of comprehensive income.
(p) Revenue recognition
The Group recognizes revenue when persuasive evidence of an arrangement exists, delivery has occurred and/or service has been performed, the price is fixed or determinable and collection is reasonably assured.
In accordance with ASC 605-45, the Company adopts net presentation method for its revenue, under which revenues are net of business tax, related surcharges and value added tax.
Revenues presented in the consolidated statements of comprehensive income include revenues from mobile value added services that are comprised of consumer mobile security and mobile games, advertising services, enterprise mobility and other services.
Mobile Value Added Services Revenues
Consumer mobile security revenues
Consumer mobile security revenues are derived principally from providing premium mobile security and productivity services to end users. The basic functions of security and productivity services, including anti-virus, anti-malware, anti-spam, privacy protection, data backup and recovery are free of charge. The customers are charged for updating the anti-virus database on a pay-per-use basis or paying a fee to subscribe to the premium security and productivity services including continuous update of anti-virus database, continuous update of the semantics of anti-spam, and advanced privacy protection on a monthly, quarterly, semi-annually or annually basis. The Group recognizes revenue for premium services considered to be software-related (e.g., mobile security services) in accordance with industry specific accounting guidance for software and software-related transactions. For premium services where the customer does not take possession of fully-functioning software (e.g., mobile productivity services), the Group recognizes revenue pursuant to ASC 605, Revenue Recognition. Provided collectability is probable, revenue is recognized over the usage period which is the same for software-related services and services where software is incidental to the provision of the services. Basic functions and customer support are provided to end users free of charge, whether they subscribe to services or not. Customer arrangements may include premium mobile security and productivity services which are multiple elements. Revenue on arrangements that include multiple elements is allocated to each element based on the relative fair value of each element. Fair value is generally determined by vendor-specific- objective-evidence (“VSOE”). For all the periods presented, the usage period for the elements in arrangements that include multiple elements is the same. No allocation was performed as there is no impact from the allocation on revenue recognized.
Revenue for pay-per-use services is recognized on a per-use basis when the update is made. Proceeds from sale of subscription services are deferred when received and revenue for the subscription services is recognized on a straight-line basis over the estimated service period provided all revenue recognition criteria have been met.
The payment channels include wireless carriers and service providers, independent distributors of prepaid cards, and third-party payment processors.
Wireless carriers and service providers. The Group, via service providers, cooperates with wireless carriers to provide consumer mobile security services to the customers. In China, service providers have the exclusive licenses to contract with wireless carriers in offering consumer mobile security services to the end users and they are mainly responsible for assisting in the billing of consumer mobile security services. Wireless carriers are mainly responsible for billing, collection and customer support relating to the end users. Under certain circumstances, the Group itself is a service provider and contract directly with wireless carriers.
Fees paid for premium service are charged to the customers’ telephone bills and shared between us and wireless carriers. The sharing percentage is fixed and determined by wireless carriers. The Group does not enter into arrangements directly with the wireless carriers except when the Group acts as a service provider and the wireless carriers are not acting as an agent for us in the transactions. Therefore, the revenue recognized is net of the amounts retained by the wireless carriers.
The Group recognizes and report consumer mobile security services revenues on a gross basis based on service providers’ portion of the billings as the Group has the primary responsibility for fulfillment and acceptability of the consumer mobile security services and are considered a principal in the transactions. The amounts attributed to services providers’ share are determined pursuant to the arrangements between services providers and us and are recognized as costs of revenues.
To recognize consumer mobile security services revenues, the Group relies on wireless carriers and service providers to provide us with the billing confirmations for the amount of services they have billed to their mobile customers. At the end of each reporting period, when the wireless carriers or service providers are yet to provide us the monthly billing confirmations, the Group uses information generated from internal system as well as the historical data to estimate the amounts of collectable consumer mobile security services fees and to recognize revenue. Historically, there have been no significant adjustments to the revenue estimates.
Prepaid cards. The Group sells prepaid cards to customers through independent distributors. The customers can use the prepaid cards to subscribe to the premium services. Once the customers activate the premium services using the prepaid cards, the Group starts to recognize revenues on a straight-line basis over the service period. The unused cash balances remaining in users’ accounts are recorded as a liability in deferred revenue. While the Group has primary responsibility for fulfillment and acceptability, the Group does not have control of, and generally do not know, the ultimate selling price of the prepaid cards sold by the distributors, and therefore, net proceeds from the distributors form the basis of revenue recognition.
Third-party payment processors. The customers can also subscribe to premium services directly through the Company’s website and the billings are handled by third-party payment processors. Under these circumstances, the Group has the primary responsibility for fulfillment and acceptability and recognizes the revenue on a gross basis. The amounts attributed to third-party payment processors are recognized as costs of revenue.
Mobile games revenues
Mobile game revenues are derived principally from game operations for both third-party developed mobile games and self-developed mobile games and game licensing of self-developed mobile games to other third-party game operators.
Mobile game operations. The Group generates mobile games revenues from operating and publishing mobile games developed by third parties and itself. The Group enters into exclusive or joint operation agreements with developers for licensed mobile game applications. The Group distributes the games on Apple’s App Store, Android platforms, FL Mobile’s platforms and other channels (collectively, “Platforms”). Game players can download the free-to-play games and pay to acquire virtual currency which can be redeemed in the game for in-game virtual items.
The Group sells both consumable and durable virtual goods in games. Consumable goods are items that are used up one-time, while durable goods are items accessible to the user over an extended period of time. For games under joint operation, the Group recognizes revenue from the sales of both consumable goods and durable goods at once when the virtual items are delivered. For games under exclusive operations, the Group recognizes revenue from the sales of consumable goods when the goods are used up. The Group recognizes revenue from the sales of durable goods ratably over the estimated average playing period of paying users.
The Groups estimates the playing periods of paying users based on available data obtained since September 2012. On a quarterly basis, the Groups determines the estimated average playing period for paying players on a game by game basis, beginning at the time of a payer’s first purchase in that game and ending on a date when that paying player is no longer playing the game. The Group then calculates the average of the time periods from the first purchase date to the date the last player is expected to cease playing the game for each game player to determine the total average playing period for that game.
The Group determines that a paying player will cease playing a game once the Inactive Period has occurred. The Group defines the Inactive Period as the time period after which if a paying player has not logged onto a game, the possibility that he/she will continue to play the game in the future is very low. To determine the Inactive Period, the Group regularly analyzes the paying players’ activities on games to determine when the paying players stop playing the games. For the players who have not logged onto a game for 50 days as of the period end, the Group deems them inactive players. For the players who have not logged onto a game for less than 50 days as of the period end, the Group deems that they will cease to play the game after 90 days from the last date when they logged onto the game before the period end.
Currently estimated average playing periods of the mobile games are three months, based on current available game player information. The Group regularly reassesses these estimates and may revise such estimates in the future as additional game data becomes available and if and when future data indicates a change in playing patterns or behaviors.
Pursuant to agreements signed between the Group and game developers and between the Group and Platforms, revenues from the sale of game currency to be used for the purchase of virtual items are shared among the Group, game developers and Platforms for third-party developed games and between the Group and Platforms for self-developed games, based on a pre-agreed ratio for each game.
The determination of whether to record these revenues using gross or net method is based on an assessment of various factors. The primary factors are whether the Group is acting as the principal in offering services to the game players or as an agent in the transaction, and the specific requirements of each agreement.
For third-party developed games under exclusive operation agreements and self-developed games, the Group recognizes revenue based on the gross amount billed to customers (i.e., inclusive of the amount retained by Platforms and the amounts paid to game developers under revenue-sharing arrangements if any), because the Group is able to determine pricing for the virtual items sold and is the primary obligor to the customers. The amount paid to Platforms and game developers are recorded as cost of services.
For third-party developed games under joint operation agreements, the game developer is considered the primary obligor to the customers and has latitude in establishing price. The Group accounts for such sales on a net basis by recognizing the commission it retains from each sale (i.e., revenue net of the amount retained by Platforms and the amounts paid to game developers under revenue-sharing arrangements).
To determine whether the Platform plays a role of primary obligor or an agent, the Group has considered ASC 605-45-45 and concluded that the Platform is an agent in the sale of in-game virtual items to the customers because it 1) is not responsible for the fulfillment of in-game virtual items and does not take overall responsibility of the services provided to the customers, 2) does not have pricing latitude and only receives a fixed commission, 3) does not have inventory risk, 4) does not change the virtual items sold or determine specifications of the game or the virtual items sold, and 5) does not have credit risk. In the case of self-developed games and third-party developed games under exclusive operation by the Group, Platforms are the agents of the Group. In the case of third-party developed games under joint operation, Platforms are the agents of the game developers.
Mobile game licensing. The Group licenses its self-developed games to other third-party game operators and generally receives revenue in forms of initial license fees, non-refundable minimum guarantee, monthly revenue-based fees under revenue-sharing arrangement or a combination. The initial license fee is generally a fixed amount and recognized ratably over the term of the license. The non-refundable minimum guarantee is generally a fixed amount and recognized once the fees are collected. The revenue-based fees under revenue-sharing arrangement are generally equal to a fixed percentage of the revenues generated by the game operators from the sale of virtual items and are recognized when the game operators provide the Group the monthly billing confirmation.
Advertising Revenues
Advertising revenues are derived principally from promotion of third-parties’ applications, games or services over a particular period of time, through a variety of patterns, which are classified into online advertising services and offline advertising services.
Online advertising revenues. The Group promotes third-parties’ games and applications through NQ security applications and interest-based online community applications in a variety of forms including but not limited to offer-walls, push-notification, and content integrations. Advertising fees are generally charged to advertisers on the cost per action (“CPA”) basis. The desired actions to be performed include but are not limited to activation, download, click, registration or opt-ins, which are determined by the advertisers. The revenues are generally recognized when the end users activate the applications, register accounts or deliver their opt-ins.
The Group also provides advertising services by embedding the advertisement in applications developed by third-party content providers. The Group signs agreements with advertisers and content providers separately. The determination of whether to record these revenues using gross or net method is based on an assessment of various factors. The primary factors are whether the Group is acting as the principal in offering services to advertisers or as an agent in the transaction, and the specific requirements of each agreement. After considering the Company’s obligations and risks, latitude in establishing price, determination of service specifications and etc., the Group concludes that the Group is the primary obligor in the contracts with advertisers. The fees are charged to advertisers on the CPA basis. The revenues are recognized by us on a gross basis pursuant to ASC 605-45, including payments to content providers. The advertising fees paid to the third-party content providers are recognized as costs of services.
Moreover, the Group provides advertisement placements on the Company’s websites and interest-based communities. The Group enters into pay-for-time (“CPT”) contracts with advertisers, under which the fixed price and advertising services are established upfront and charged ratably over the contractual period of display.
Offline pre-installation revenues. The Group provides with the pre-installation services to promote various applications in mobile phones. The revenues are recognized when the end users activate the applications or become active users within certain periods, pursuant to the contracts.
Enterprise Mobility Revenues
Enterprise mobility revenues are derived principally from hardware sales to enterprise users, technology and software development, and commission income shared from mobile network operators, all of which are provided on a stand-alone basis in the year of 2013.
The revenue from sale of hardware is recognized upon the time of delivery. Hardware is considered delivered to customers once customers acknowledge the receipt of the hardware delivered and the title and risk of loss have been transferred. For most of the hardware sales, these criteria are met at the time customers sign off the delivery notes.
The Group recognizes the revenue from technology and software development upon the delivery and acceptance by customers of the standard proprietary software or tailored enterprise software, which involves significant production, modification, or customization. These software arrangements generally include the right to postcontract customer support (“PCS”). The Group recognizes the technology and software development revenues immediately after the Group delivers the software since PCS is assessed insignificant after considering the facts of (i) no additional charges are incurred for PCS; (ii) all PCS are normally for a period of 6 months to 1 year; (iii) the estimated cost for such services is insignificant based on historical records; and (iv) the Group does not offer upgrades or enhancements to the software during PCS period and these services are expected to continue to be infrequent. The Group adopts completed-contract method to account for revenues from technology and software development, given the substantive acceptance terms in arrangements and short duration of development.
Commission income is derived from bringing enterprise users to the mobile network operators and is determined based on fixed percentages of actual charges to the enterprise users as agreed with the mobile operators. Commission incomes are recognized in the month in which the service is provided to the enterprise users. For the amount of revenues to be recognized, the Group firstly estimates the amount of service fee and recognizes revenue based on the fixed commission rates as stipulated on the contract that multiply the estimated customer charges. When the Group later receives the statements of actual charge issued by the mobile network operators, the Group records a true-up adjustment. Based on the historical experience, there had not been any material adjustments incurred.
Other Services Revenues
Other services revenues are derived principally from providing technology development and training services. The Group recognizes these revenues when performance is completed.
(q) Cost of revenues
Cost of revenues primarily consists of customer acquisition cost paid to third party business partners based on number of end users referred by them, which are expensed when earned by third party business partners, fees paid to the handset makers and promotion agents for them to preload the Group’s software and fees paid to or retained by SPs and third party payment processors for their services relating to the billing of the Group’s consumer mobile security revenues. Cost of revenues also includes the hardware procurement cost for enterprise mobility business, as well as fees paid to third-party content providers for advertising services and mobile game operations. Staff costs of those departments directly involved in providing mobile value added services, enterprise mobility and advertising services, as well as other services are also included in cost of revenues.
(r) Marketing and Advertising costs
Marketing and Advertising costs consist primarily of costs for the promotion of corporate image and product marketing. The Group expensed all marketing and advertising costs as incurred. Marketing and advertising costs for the years ended December 31, 2011, 2012 and 2013 are US$2,929, US$8,546 and US$13,318, respectively.
(s) Research and development
Research and development related expenses consist primarily of payroll-related expenses incurred for new product development and product enhancements. The Group expenses all costs incurred for the development of mobile security and productivity software, technology and software for enterprise customers, and technology of mobile platforms when incurred prior to the establishment of technological feasibility. Once the software has reached technological feasibility with a proven ability to operate in the market, all subsequent software development costs shall be capitalized until that software is marketed. The amount of costs qualifying for capitalization has been immaterial and, as a result, the Group did not capitalize any research and development costs for the years ended December 31, 2011, 2012 and 2013.
(t) Operating lease
Leases where substantially all the risks and rewards of ownership of the assets remain with the leasing company are accounted for as operating leases. Payments made under operating leases are charged to the consolidated statements of comprehensive income on a straight line basis over the lease periods.
(u) Gain on change of interest in an associate
The gain on change of interest in an associate represents the difference at the time of change of interest in an associate between the transfer price and carrying amount of the interest transferred. The Group recognized a gain of US$943 from the change of equity interest in FL Mobile in the year ended December 31, 2012. See Note 4 – “Business Combination”. No sale of interest in an associate occurred in the year ended December 31, 2013.
(v) Government Grant
Government grant is recorded as a liability in deferred revenue when receive upfront, and recognize as other income or reduction of related expense in the period when (i) all of the conditions attached to the subsidy are satisfied or it is not subject to future return or reimbursement, and (ii) the subsidies have been received or become receivable with reasonable assurance. The Group recorded subsidies from the PRC government of US$155, US$40 and US$761 in other income for the years ended December 31, 2011, 2012 and 2013, respectively.
(w) Employee benefits
Full-time employees of the Group in mainland China are entitled to staff welfare benefits including medical care, welfare subsidies, unemployment insurance and pension benefits through a PRC government-mandated multi-employer defined contribution plan. The Group is required to accrue for these benefits based on certain percentages of the employees’ salaries. The Group is required to make contributions to the plans out of the amounts accrued. The PRC government is responsible for the medical benefits and the pension liability to be paid to these employees and the Group’s obligations are limited to the amounts contributed.
The Group recorded employee benefit expenses of US$1,250, US$1,845 and US$4,393 for the years ended December 31, 2011, 2012 and 2013, respectively.
(x) Share-based compensation
The Group grants share options and restricted shares to its selected employees, directors and non-employee consultants. Awards granted to employees with service conditions attached are measured at the grant date fair value and are recognized as an expense using graded vesting method, net of estimated forfeitures, over the requisite service period, which is generally the vesting period. The estimate of forfeitures will be adjusted over the requisite service period to the extent that actual forfeitures differ, or are expected to differ, from such estimates. Changes in estimated forfeitures will be recognized through a cumulative catch-up adjustment in the period of change and will also impact the amount of share-based compensation expense to be recognized in future periods.
Awards granted to employees with performance conditions attached are measured at fair value on the grant date and are recognized as the compensation expenses in the period and thereafter when the performance goal becomes probable to achieve.
Awards granted to employees with market conditions attached are measured at fair value on the grant date and are recognized as the compensation expenses over the estimated requisite service period, regardless of whether the market condition has been satisfied if the requisite service period is fulfilled.
Awards granted to non-employees are measured at fair value at the earlier of the commitment date or the date the services are completed, and are recognized using graded vesting method over the period the service is provided.
Binomial option-pricing models are adopted to measure the value of awards at each grant date or measurement date. The determination of fair value is affected by the share price as well as assumptions relating to a number of complex and subjective variables, including but not limited to the expected share price volatility, actual and projected employee and non-employee share option exercise behavior, risk-free interest rates and expected dividends. The use of the option-pricing model requires extensive actual employee and non-employee exercise behavior data for the relative probability estimation purpose, and a number of complex assumptions.
(y) Non-controlling interest
Non-controlling interest represents the equity interest in subsidiaries that is not attributable, either directly or indirectly, to the Company’s shares in such subsidiaries. The non-controlling interest is presented in the consolidated balance sheets, separately from equity attributable to the shareholders of the Company. Non-controlling interest in the results of the Company is presented on the face of the consolidated statements of comprehensive income as an allocation of the total profit or loss for the periods between non-controlling shareholders and the shareholders of the Company.
(z) Treasury Shares
The Company accounted for those shares repurchased as treasury shares at cost in accordance with ASC 505-30, and the treasury shares acquired are shown separately in the shareholders’ equity as the Company has not yet decided on the ultimate disposition of those shares. If and when the Company cancels the treasure shares, the difference between the original issuance price and the repurchase price will be debited into additional paid-in-capital.
(aa) Income tax
Current income tax is provided on the basis of income for financial reporting purpose, adjusted for income and expense items which are not assessable or deductible for income tax purpose, in accordance with the regulations of the relevant tax jurisdictions. Deferred income tax is accounted for using the liability approach which requires the recognition of income tax payable or refundable for the current year and deferred income tax liabilities and assets for the future tax consequences of events that have been recognized in the Group’s financial statements or tax returns. Deferred income tax is determined based on the differences between the financial reporting and tax basis of assets and liabilities and is measured using the currently enacted income tax rates and laws. The effect on deferred income tax assets and liabilities of a change in income tax rates is recognized in the consolidated statements of comprehensive income in the period when such changes are enacted. A valuation allowance is provided to reduce the carrying amounts of deferred income tax assets if it is considered more likely than not that a portion or all of the deferred income tax assets will not be realized.
(ab) Uncertain tax position
The Group adopts a more likely than not threshold and a two-step approach for the tax position measurement and financial statement recognition. Under the two-step approach, the first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained, including resolution of related appeals or litigation process, if any. The second step is to measure the tax benefit as the largest amount that is more than 50% likely of being realized upon settlement.
(ac) Statutory reserve
The Company’s PRC subsidiaries, VIEs and the VIEs’ subsidiaries in China are required to make appropriations to certain non-distributable reserve funds.
In accordance with the laws applicable to China’s Foreign Investment Enterprises, the Company’s subsidiaries that are foreign investment enterprises in China have to make appropriations from their after-tax profit (determined under the Accounting Standards for Business Enterprises promulgated by the Ministry of Finance of the People’s Republic of China (“PRC GAAP”)) to reserve funds including (i) general reserve fund; (ii) enterprise expansion fund; and (iii) staff bonus and welfare fund. The appropriation to the general reserve fund must be at least 10% of the after-tax profits calculated in accordance with PRC GAAP. Appropriation is not required if the reserve fund has reached 50% of the registered capital of the respective companies. Appropriations to the other two reserve funds are subject to discretion of respective companies.
In accordance with China Company Laws, the Company’s PRC subsidiary, VIE and the VIE’s subsidiaries that are domestic companies, must make appropriations from their after-tax profit (determined under PRC GAAP) to non-distributable reserve funds including (i) statutory surplus funds; and (ii) discretionary surplus fund. The appropriation to the statutory surplus fund must be at least 10% of the after-tax profits calculated in accordance with PRC GAAP. Appropriation is not required if the surplus fund has reached 50% of the registered capital of the respective companies. Appropriation to the discretionary surplus fund is made at the discretion of respective companies.
The use of the general reserve fund, statutory surplus fund and discretionary surplus fund are restricted to the offsetting of losses or increase of registered capital of the respective companies. These reserves are not allowed to be transferred to the Company in any forms of cash dividends, loans or advances, nor can they be distributed except under liquidation.
For the years ended December 31, 2011, 2012 and 2013, profit appropriation to the general reserve fund and the statutory surplus fund (“statutory reserve”) totaled US$nil, US$2,938 and US$6,698, respectively, and there was no profit appropriation to other reserve funds for any of those years.
(ad) Earnings (loss) per share
Basic earnings (loss) per share is computed using the weighted average number of common shares outstanding during the year. Diluted earnings (loss) per share is computed using the weighted average number of common shares and potential common shares outstanding during the period for options and restricted shares under treasury stock method and for convertible debts under if-convertible method, if dilutive. Potential common shares are not included in the denominator of the diluted earnings per share calculation when inclusion of such shares would be anti-dilutive, such as in a period in which a net loss is recorded. Earnings per share is computed on Class A common shares and Class B commons shares together, because both classes have the same dividend rights and the same participation rights in the Company’s undistributed earnings.
(ae) Related parties
Parties are considered to be related if one party has the ability, directly or indirectly, to control the other party or exercise significant influence over the other party in making financial and operating decisions. Parties are also considered to be related if they are subject to common control or significant influence, such as a family member or relative, stockholder, or a related corporation.
(af) Comprehensive income
Comprehensive income is defined as the change in equity of the Group during a period from transactions and other events and circumstances excluding those resulting from investments by and distributions to shareholders. Accumulated other comprehensive income/(loss), as presented on the accompanying consolidated balance sheets, consists of cumulative foreign currency translation adjustment and unrealized gain or loss from available-for-sale investments.
(ag) Segment reporting
Operating segments are defined as components of an enterprise engaging in business activities about which separate financial information is available that is evaluated regularly by the Group’s chief operating decision-maker (“CODM”), the Chief Executive Officer, in deciding how to allocate resources and assess performance.
The Company’s organizational structure is based on a number of factors that the CODM uses to evaluate, view and run the Company’s business operations, which include, but are not limited to, customer base, homogeneity of products and technology. The Company’s operating segments are based on its organizational structure and information reviewed by the Company’s CODM to evaluate the operating segment results.
The Company has determined that the business segments that constitute its primary reportable segments are consumer and enterprise. The consumer segment primarily consists of mobile value added services, which includes mobile security services and mobile games, advertising services and other services. The enterprise segment mainly consists of technology and software development services and hardware sales aggregated under enterprise mobility revenues.
Before 2012, the Group principally engaged in consumer mobile security and other services and operated and managed this business as a single segment. In 2012, the Group expanded its business by the acquisition of NationSky in enterprise mobility services and the acquisition of FL Mobile and its subsidiary, Red, in mobile games and advertising services. In 2013, the Group enhanced its business in enterprise mobility services and advertising services by a series of acquisitions, and generates revenue from the operations of such businesses. See Note 4 – “Business Combination” for more details.
The Company’s CODM separately reviewed key information of each of two operating segments consisting of consumer and enterprise, in order to optimize the management of operations. The Group’s reportable segments are strategic business units that offer different products and services. They are managed separately because each business requires different technology and marketing strategies as they are facing different group of customers.
(ah) Fair value measurement
The Company’s financial instruments include cash equivalents, term deposits, short-term investments, accounts receivable, certain other current and non-current assets, accounts payable, accrued expenses and other current liabilities and other non-current liabilities. For fair value measurement, U.S. GAAP establishes a three-tier hierarchy which prioritizes the inputs used in the valuation methodologies in measuring fair value:
Level 1—observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets.
Level 2—other inputs that are directly or indirectly observable in the marketplace.
Level 3—unobservable inputs which are supported by little or no market activity.
The fair value hierarchy also requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. See Note 12 – Fair value measurements.
(ai) Effect of Recent Accounting Pronouncements
In March of 2013, the FASB issued guidance on “Foreign Currency Matters, Parent’s accounting for the Cumulative Translation Adjustment upon Derecognition of Certain Subsidiaries or Groups of Assets within a Foreign Entity or of an Investment in a Foreign Entity.” The main provisions of these amendments are to require the parent to apply the guidance in Subtopic 830-30 to release any related cumulative translation adjustment into net income, when a reporting entity (parent) ceases to have a controlling financial interest in a subsidiary or group of assets that is a nonprofit activity or a business (other than a sale of in substance real estate or conveyance of oil and gas mineral rights) within a foreign entity. For an equity method investment that is a foreign entity, a pro rata portion of the cumulative translation adjustment should be released to net income upon a partial sale of such an equity method investment. Additionally, the amendments are also applied to business combination that result in an acquirer obtaining of control of an acquiree in which it held an equity interest immediately before the acquisition date (sometimes also referred to as a step-acquisition). The amendments are effective prospectively for fiscal year (and interim reporting periods within those years) beginning after December 15, 2013. The Group is currently evaluating the impact on its consolidated financial statement of adopting this guidance.
In June 2013, the FASB issued guidance on “Financial Services-Investment Companies, Amendments to Scope, Measurement, and Disclosure Requirements.” The amendments change the approach to the investment company assessment in Topic 946, clarify the characteristics of an investment company, and provide comprehensive guidance for assessing whether an entity is an investment company. In addition, the amendments require an investment company to measure the non-controlling ownership interests in other investment companies at fair value rather than using the equity method of accounting. Moreover, the amendments require the additional disclosure about (a) the fact that the entity is an investment company and is applying the guidance in Topic 946, (b) information about changes, if any, in an entity’s status as an investment company, and (c) information about financial support provided or contractually required to be provided by an investment company to any of its investees. This amendment is effective for an entity’s interim and annual reporting periods in fiscal years that begin after December 15, 2013. The Group re-evaluated the characteristics of NQ Guotai, an equity investment company of the Group, in accordance with the updated guidance. Based on the assessment, NQ Guotai is still within the scope of investment companies and shall be accounted for using fair value approach.
In July of 2013, the FASB issued guidance on “Income Taxes – Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists.” The amendments clarify that an unrecognized tax benefit, or a portion of an unrecognized tax benefit, should be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss, similar tax loss, or tax credit carryforward, except as noted in the following sentence. To the extent a net operating loss, similar tax loss, or tax credit carryforward is not available at the reporting date under the tax law of the applicable jurisdiction to settle an additional income taxes that would result from the disallowance of a tax position or the tax law of the applicable jurisdiction does not require the entity to use, and the entity does not intend to use, the deferred tax asset for such a purpose, then under this exception the unrecognized tax benefit is to be presented in the financial statements as a liability and should not be combined with (netted with) the deferred tax asset(s). The assessment of whether a deferred tax asset is “available” is based on the unrecognized tax benefit and deferred tax asset amounts that exist at the reporting date and should be made presuming disallowance of the tax position at the reporting date. The amendments are effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. The Group had evaluated that there was no impact on its consolidated financial statements of adopting this guidance.
In May of 2014, the FASB issued Topic 606, “Revenue from Contracts with Customers”. This topic clarifies the principles for recognizing revenue and develops a common revenue standard for U.S. GAAP and IFRS. Simultaneously, this topic supersedes the revenue recognition requirements in Topic 605, Revenue Recognition, and most industry-specific guidance throughout the Industry Topics of the Codification. The core principle of the guidance requires an entity to recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. To achieve that core principle, an entity should apply the five steps: 1) identify the contract(s) with a customer; 2) identify the performance obligations in the contract; 3) determine the transaction price; 4) allocate the transaction price to the performance obligations in the contract; 5) recognize revenue when (or as) the entity satisfies a performance obligation. The amendments are effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. Early application is not permitted. This amendments shall be applied retrospectively either to each prior reporting periods or with the cumulative effect of initially applying this amendments recognized at the date of initial application. There is no impact on the consolidated financial statements for current reporting periods since early adoption is not permitted. The Group is in process of evaluating the cumulative effect on the consolidated financial statements of adopting this guidance so as to transit to the new revenue recognition guidance in the year of 2016.
In June of 2014, the FASB issued guidance on “Stock Compensation –Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period”. The amendments clarify that a performance target that affects vesting and that could be achieved after the requisite service period should be treated as a performance condition. As such, the performance target should not be reflected in estimating the grant-date fair value of the award. No matter when the performance target becomes probable of being achieved, the compensation cost should be recognized in the period in which it becomes probable that the performance target will be achieved and should represent the compensation cost attributable to the period(s) for which the requisite service has already been rendered. The amendments are effective for annual periods and interim periods within those annual periods beginning after December 15, 2015. Earlier adoption is permitted. The Group had evaluated that there is no impact on the consolidated financial statements of adopting this guidance.
As of October 15, 2014, the Financial Accounting Standards Board (“FASB”) has issued ASU No. 2013-01 through ASU 2014-15, which are not expected to have a material impact on the consolidated financial statements upon adoption.

	For Enterprise Business
	Acquisition of NationSky
	On May 11, 2012, the Group acquired 55% of the equity interests in NationSky, which is engaged in enterprise mobility services, for cash consideration of US$3,157 and 2,300,000 common shares of the Company, the fair value of which was US$4,196. The Group began to consolidate NationSky’s financial statements on June 1, 2012. The purpose of the acquisition was to expand into the enterprise mobility market.
	On the acquisition date, the fair value of share consideration is measured based on the market price of the Company’s share on the acquisition date. The valuations used in the purchase price allocation were determined by the Company with the assistance of an independent third party valuation firm with the income approach applied. The allocation of the consideration for assets acquired, liability assumed and non-controlling interest based on their fair value was as follows (in thousands):
		As of May 11, 2012
		US$
	Cash consideration		3,157
	Shares consideration		4,196
	Total consideration transferred		7,353
	Cash		3,892
	Other tangible assets		4,482
	Identifiable intangible assets acquired		5,058
	Liability assumed		(3,367	)
	Goodwill		2,083
	Fair value of non-controlling interest		(4,795	)
	Total		7,353
	Total identifiable intangible assets acquired upon acquisition mainly include customer relationships of US$1,310 with an estimated useful life of 6.6 years, revenue sharing agreements of US$2,462 with estimated useful life of 7.6 years, non-compete agreement of US$347 with estimated useful life of 6.6 years, and platform technology to develop the customized mobile applications of US$939 with estimated useful life of 5 years.
	The excess of the purchase price over the tangible assets, identifiable intangible assets acquired and liabilities assumed was recorded as goodwill relating to enterprise segment. Goodwill primarily represents the expected synergies from combining operations of NationSky with those of the Group, which are complementary to each other, and intangible assets that do not qualify for separate recognition. In accordance with ASC350, goodwill is not amortized but is tested for impairment and is not deductible for tax purposes.
	The fair value of non-controlling interest in NationSky has been determined in the valuation mainly based on the number of shares held by non-controlling shareholders and the equity value close to the acquisition date, taking into consideration a 20% discount for lack of control. The equity value close to the acquisition date was implied by the fair value of cash and shares transferred on the acquisition date as consideration for the acquisition.
	The amount of net revenue and net income of NationSky included in the Group’s consolidated statements of comprehensive income from the acquisition date to December 31, 2012 are US$12,552 and US$1,184, respectively, for the year ended December 31, 2012.
	Prior to the acquisition, NationSky did not prepare its financial statements in accordance with U.S. GAAP. The Company determined that the cost of reconstructing the financial statements of NationSky for the periods prior to the acquisition outweighed the benefits. Thus the Company’s management believes the presentation of pro forma financial information with respect to the results of operations of the Group for the business combination is impracticable.
	On July 15, 2013, Beijing Technology acquired all of the remaining equity interest of NationSky held by the non-controlling shareholder, representing 45% of the outstanding share capital of NationSky, for an aggregate cash consideration of approximately US$11,024 and 8,352,940 common shares of the Company, the fair value of which is US$16,355.

The Group began to consolidate NQ Shenzhen’s financial statements on June 30, 2013. The purpose of the acquisition was to add a new category of software services to the Group’s growing product portfolio and expand the business into youth education industry.

The valuations used in the purchase price allocation were determined by the Company with the assistance of an independent third party valuation firm with the income approach applied.

	Total		2,934
	Total identifiable intangible assets acquired include customer relationships of US$243 with an estimated useful life of 3 years and platform technology of US$356 with an estimated useful life of 5 years.
	The excess of the purchase price over the tangible assets, identifiable intangible assets acquired and liabilities assumed was recorded as goodwill relating to enterprise segment. Goodwill primarily represents the expected synergies from combining operations of NQ Shenzhen with those of the Group, which are complementary to each other and intangible assets that do not qualify for separate recognition. In accordance with ASC350, goodwill is not amortized but is tested for impairment and is not deductible for tax purposes.
	The amount of net revenue and net losses of NQ Shenzhen included in the Group’s consolidated statements of comprehensive income from the acquisition date to December 31, 2013 are US$297 and US$19, respectively, for the year ended December 31, 2013.
	Prior to the acquisition, NQ Shenzhen did not prepare its financial statements in accordance with US GAAP. The Company determined that the cost of reconstructing the financial statement of NQ Shenzhen for the periods prior to the acquisition outweighed the benefits. Based on an assessment of the financial performance of all companies acquired by the Group and a comparison of NQ Shenzhen’s and the Group’s financial performance for the fiscal year prior to the acquisition, the Group did not consider NQ Shenzhen on its own to be material to the Group. Thus the Group’s management believes that the presentation of pro forma financial information with respect to the results of operations of the Group for the business combination is impractical.

	For Consumer Business
	Acquisition of FL Mobile and Red
On September 1, 2010, Beijing Technology signed an agreement under which Beijing Technology paid US$2,462 to FL Mobile, which was engaged in the promotion services of mobile applications in China, in exchange for 1) 33% of the equity interests in FL Mobile, and 2) the prepaid customer acquisition cost. The Group estimated separately the fair value of its equity investment and the fair value of the prepaid customer acquisition cost. Based on their relative fair value, the Group allocated US$1,007 as equity investment and US$1,455 as prepaid customer acquisition cost. The prepaid customer acquisition cost is being amortized until November 30, 2012 based on the number of estimated users developed for each reporting period under this program. The investment was accounted for under the equity method of accounting due to the Group’s inability to control FL Mobile prior to November 30, 2012.
In July 2012, the Company, through Beijing Technology, and all other shareholders of FL Mobile transferred 20% of the equity interest in FL Mobile to a new shareholder, in exchange for the transfer of certain intangible assets. Accordingly the equity interest of the Company on FL Mobile was decreased from 33% to 26.4%. The fair value of the intangible assets being valued were higher than the carrying amount of the equity interest which the Company transferred, which resulted in a gain of US$943 recorded by the Company as changes of interest in an associate for the year ended December 31, 2012.
On November 30, 2012, the Group acquired Red and the remaining equity interests in FL Mobile for the consideration of 12,346,647 common shares of the Company with certain sales restrictions, the fair value of which was US$16,421. As a result of this acquisition, the Group also made Red a wholly owned subsidiary of FL Mobile. The Company began to consolidate the consolidated financial statements of FL Mobile commencing on December 1, 2012. The purpose of the acquisition was to offer mobile games and interest-based community applications to the customers through FL Mobile’s platform.
On the acquisition date, the fair value of share consideration is measured based on the market price of the Company’s share on the acquisition date. The valuations used in the purchase price allocation were determined by the Company with the assistance of an independent third party valuation firm with the income approach applied. The allocation of the consideration for assets acquired, liability assumed and previously held equity interests based on their fair value was as follows (in thousands):
	As of November 30, 2012
	US$
Fair value of previously held 26.4% equity interests		5,568
Consideration transferred		16,421
Total		21,989
Cash		490
Other tangible assets		4,167
Identifiable intangible assets acquired		4,977
Liability assumed		(3,493	)
Goodwill		15,848
Total		21,989
In accordance with ASC 805 in a business combination achieved in stages the Group re-measured its previously held equity interest in FL Mobile on its acquisition-date fair value using the discounted cash flow method and recognized a gain of US$2,882 in other income for the year ended December 31, 2012. The significant inputs used in the valuation of the Group’s previously held equity interests in FL Mobile include (i) an assumed discount rate of 25%; (ii) an assumed terminal value based on a long-term sustainable growth rate of 3%; (iii) an assumed discount for lack of marketability of 25%; and (iv) the operating projections which are estimated based on historical pattern, future business plan and expected market growth rate.
Total identifiable intangible assets acquired upon acquisition mainly include customer relationships of US$80 with an estimated useful life of 4 years, user base of US$2,433 with an estimated useful life of 1.5 years, technology of various mobile platforms for mobile games downloading and knowledge sharing of US$2,273 with an estimated useful life of 4 years, and the self developed game acquired from Red of US$191 with an estimated useful life of 0.6 years.
The excess of the purchase price over the tangible assets, identifiable intangible assets acquired and liabilities assumed was recorded as goodwill relating to consumer segment. Goodwill primarily represents the expected synergies from combining operations of FL Mobile and Red with those of the Group, which are complementary to each other, and intangible assets that do not qualify for separate recognition. In accordance with ASC350, goodwill is not amortized but is tested for impairment and is not deductible for tax purposes.
The amount of net revenue and net income of FL Mobile and Red included in the Group’s consolidated statements of comprehensive income from the acquisition date to December 31, 2012 are US$707 and US$184, respectively, for the year ended December 31, 2012.
Prior to the acquisition, FL Mobile and Red did not prepare its financial statements in accordance with US GAAP. The Company determined that the cost of reconstructing the financial statement of FL Mobile and Red for the periods prior to the acquisition outweighed the benefits. Based on an assessment of the financial performance of all companies acquired by the Group and a comparison of consolidated financial performance of FL Mobile and Red and the Group’s financial performance for the fiscal year prior to the acquisition, the Group did not consider FL Mobile and Red as an aggregate on its own to be material to the Group. Thus the Group’s management believes that the presentation of pro forma financial information with respect to the results of operations of the Group for the business combination is impractical.
Acquisition of Fanyue
On March 21, 2013, the Group acquired 51% of the equity interest in Fanyue, which is primarily engaged in off-line user acquisition services, for cash consideration of US$88 and 808,146 common shares of the Company, the fair value of which was US$1,490.

Total		1,578
Identifiable intangible assets acquired upon acquisition represent customer relationships of US$335 with an estimated useful life of 2.8 years.
The excess of the purchase price over the tangible assets, identifiable intangible assets acquired and liabilities assumed was recorded as goodwill relating to consumer segment. Goodwill primarily represents the expected synergies from combining operations of Fanyue with those of the Group, which are complementary to each other, and intangible assets that do not qualify for separate recognition. In accordance with ASC350, goodwill is not amortized but is tested for impairment and is not deductible for tax purposes.
The fair value of non-controlling interest in Fanyue has been determined in the valuation mainly based on the number of shares held by non-controlling shareholders and the equity value under non-controlling basis close to the acquisition date. The equity value under non-controlling basis was determined using discounted cash flow method considering the 6% premium to the discount rate of 25% used in controlling basis to reflect lack of control associated with non-controlling interest shareholders.
Prior to the acquisition, Fanyue did not prepare its financial statements in accordance with U.S. GAAP. The Company determined that the cost of reconstructing the financial statements of Fanyue for the periods prior to the acquisition outweighed the benefits. Based on an assessment of the financial performance of all companies acquired by the Group and a comparison of Fanyue’s and the Group’s financial performance for the fiscal year prior to the acquisition, the Group did not consider Fanyue on its own to be material to the Group. Thus the Group’s management believes that the presentation of pro forma financial information with respect to the results of operations of the Group for the business combination is impractical.
On September 13, 2013, FL Mobile entered into an agreement to acquire all of the remaining equity interest of Fanyue held by the non-controlling shareholders, representing 49% of the outstanding share capital of Fanyue, for aggregate cash consideration of approximately US$86 and 5,359,490 common shares of the Company, the fair value of which is US$23,410.

Goodwill primarily represents the expected synergies from combining operations of Tianya with those of the Group, which are complementary to each other, and intangible assets that do not qualify for separate recognition. In accordance with ASC350, goodwill is not amortized but is tested for impairment and is not deductible for tax purposes.
The amount of net revenue and net income of Tianya included in the Company’s consolidated statements of comprehensive income from the acquisition date to December 31, 2013 are US$1,017 and US$276, respectively, for the year ended December 31, 2013.
Prior to the acquisition, Tianya did not prepare its financial statements in accordance with US GAAP. The Company determined that the cost of reconstructing the financial statement of Tianya for the periods prior to the acquisition outweighed the benefits. Based on an assessment of the financial performance of all companies acquired by the Group and a comparison of Tianya’s and the Group’s financial performance for the fiscal year prior to the acquisition, the Group did not consider Tianya on its own to be material to the Group. Thus the Group’s management believes that the presentation of pro forma financial information with respect to the results of operations of the Group for the business combination is impractical.
Acquisition of Yinlong
In September of 2012, the Group acquired 18.9% of equity interest in Yinlong, which was mainly engaged in mobile music search and voiceprint recognition software services for a cash consideration of US$1,712. The equity investment was accounted for under the cost method, as the Group has no control or significant influence over Yinlong prior to November 11, 2013.
On November 11, 2013, the Group acquired additional 36.1% of the equity interests of Yinlong, accumulated to 55% of equity interest in Yinlong in aggregate, for a fixed cash consideration of US$2,664 and 1,409,666 common shares of the Company, the fair value of which was approximately US$3,803. The purpose of the acquisition was to acquire the core technology and mobile audio-based products of Yinlong. The Group began to consolidate Yinlong’s financial statements on December 1, 2013.
On the acquisition date, the fair value of share consideration is measured based on the market price of the Company’s share on the acquisition date. The valuations used in the purchase price allocation were determined by the Company with the assistance of an independent third party valuation firm with the income approach applied. The allocation of the consideration for assets acquired, liability assumed, previously held equity interests and non-controlling interests based on their fair value was as follows (in thousands):
	As of
	December 1, 2013
	US$
Fair value of previously held 18.9% equity interest		2,694
Cash consideration		2,664
Shares consideration		3,803
Total		9,161
Cash		386
Other current assets		1,218
Fixed assets		52
Identifiable intangible assets acquired		2,118
Goodwill		12,382
Liability assumed		(533	)
Fair value of non-controlling interest		(6,462	)
Total		9,161
Total identifiable intangible asset acquired consists of core technology of voiceprint identification of US$2,118 with an estimated useful life of 5 years.
In accordance with ASC 805 in a business combination achieved in stages the Group re-measured its previously held equity interests in Yinlong on its acquisition-date fair value using the discounted cash flow method and recognized a gain of US$942 in other income for the year ended December 31, 2013. Significant inputs used in the income approach calculation include (i) an assumed discount rate of 24.5%; (ii) an assumed terminal value based on a long term sustainable growth rate of 3%; and (iii) the operating projections which are estimated based on historical pattern, future business plan and expected market growth rate.
The fair value of non-controlling interest in Yinlong has been determined in the valuation mainly based on the number of shares held by non-controlling shareholders and the equity value under non-controlling basis close to the acquisition date. The equity value under non-controlling basis was determined using discounted cash flow method considering the 3.6% premium to the discount rate of 24.5% used in controlling basis to reflect lack of control associated with non-controlling interest shareholders.
The excess of the purchase price over the tangible assets, identifiable intangible assets acquired and liabilities assumed was recorded as goodwill relating to consumer segment. Goodwill primarily represents the expected synergies from combining operations of Yinlong with those of the Group, which are complementary to each other, and intangible assets that do not qualify for separate recognition. In accordance with ASC350, goodwill is not amortized but is tested for impairment and is not deductible for tax purposes.
The amount of net revenue and net losses of Yinlong included in the Company’s consolidated statements of comprehensive income from the acquisition date to December 31, 2013 are US$nil and US$314, respectively, for the year ended December 31, 2013.
Prior to the acquisition, Yinlong did not prepare its financial statements in accordance with US GAAP. The Company determined that the cost of reconstructing the financial statement of Yinlong for the periods prior to the acquisition outweighed the benefits. Based on an assessment of the financial performance of all companies acquired by the Group and a comparison of Yinlong’s and the Group’s financial performance for the fiscal year prior to the acquisition, the Group did not consider Yinlong on its own to be material to the Group. Thus the Group’s management believes that the presentation of pro forma financial information with respect to the results of operations of the Group for the business combination is impractical.

	Equity method investment
	In December of 2012, NQ Guotai was set up. The Group would invest RMB99,000 (US$16,238) through Tianjin QingYun, a subsidiary of Beijing Technology, in NQ Guotai in exchange for 49.5% of the equity interest. Tianjin Qingyun is a limited partner of NQ Guotai. On April 9, 2013, Beijing Wuyue Tianxia Investment Consulting Ltd, the general partner of NQ Guotai, withdrew its investment and transferred its 0.5% of the equity interest of NQ Guotai to Tianjin Qingyun for cash consideration of RMB1,000 (US$164). Meanwhile, Wangqin Guotai (Beijing) Capital Fund Management Ltd. was appointed as the new general partner and injected capital of RMB2,000 (US$328) to NQ Guotai. As of June 30, 2013, the Group fully injected the capital of RMB100,000 (US$16,402) and obtained 49.505% of equity interest in NQ Guotai. The Group accounted for the investment by equity method as the Group does not have control over NQ Guotai after considering various factors such as the board seats the Group has in the general partner of NQ Guotai. According to ASC 946, NQ Guotai meets all characteristic of an investment company and adopts fair value approach to account for its investments due to the sole purpose for returns from capital appreciation and investment income. The Group evaluated the fair value of each investment conducted by NQ Guotai by considering the development stage of each investment, work force, customer and vendor relationships, financial conditions including historical financial statements and future financial forecasts, risk factors, comparable companies in the same industry, time of investments to balance sheets date and price of recent investment by new investors, with various approaches applied, such as income approach, market approach or replacement cost approach, as appropriate. The management concluded that the fair value of all investments performed by NQ Guotai approximates to the initial costs, as no factors that may cause the significant change in fair value of investments were observed since the date of investments.

Therefore, the equity method is adopted to account for its investment in GEMA. An independent third-party valuation firm was hired to evaluate the fair value of assets and liabilities of this equity investment.

	On November 1, 2013, the Company tested impairment of goodwill at the level of reporting units, which comprise of mobile value added services excluding mobile games, mobile games, advertising and enterprise mobility. The reporting units of mobile value added services excluding mobile games, mobile games and advertising units are aggregated and presented as one reportable segment of consumer. The reporting unit of enterprise mobility is presented separately as the reportable segment of enterprise.
	The Company firstly performed qualitative analysis by taking into consideration of macroeconomics, overall financial performance and industry and market conditions, to assess whether it is more likely than not that the fair value of these reporting units were less than their carrying value. Based on the qualitative assessment, the Company determines that it is not more likely than not that the fair value of the reporting units of mobile value added services excluding mobile games, mobile games, advertising and enterprise mobility is less than their carrying value. The first and second steps of the goodwill impairment test are unnecessary.
	The management was not aware of the occurrence of any significant events or circumstance changes from the assessment date to December 31, 2013, that would be more likely than not to reduce the fair value of reporting units below their carrying values. Hence, the Group concluded that goodwill was not impaired for the year ended December 31, 2013.

	7-day depositary notice
	The Company has 7-day depositary notice of US$12,728 as of December 31, 2012. The deposits are classified within Level 2, because there generally were no quoted prices as of the reporting dates in active markets for identical term deposits. Given the short terms of these deposits, the fair value of cash equivalents approximates to cost. The balance of the deposits was included in cash and cash equivalents in consolidated Balance Sheet as of December 31, 2012. The Company has no short-term deposits as of December 31, 2013.
	Term deposits
	The Company’s term deposits include deposits with original maturities of more than three months but equal or less than one year. These term deposits are classified within Level 2, because there generally were no quoted prices as of the reporting dates in active markets for identical time deposits and therefore, in order to determine their fair value, the Company had to use observable inputs other than quoted prices in active markets for identical term deposits. The carrying amounts of term deposits approximate to their fair values due to their short-term maturities.
	Short-term investments
	To estimate the fair value of investments in financial instruments with a variable interest rate indexed to the performance of underlying assets, the Group refers to the quoted rate of return provided by banks at the end of each period using discounted cash flow method. The Group classifies the valuation techniques that use these inputs as Level 2 of fair value measurement. The financial instruments are issued by commercial banks in China with a variable interest rate indexed to performance of underlying assets. Since the Group did not intend to hold the investment over one year, they are classified as short-term investments in the year of 2012. The investment has been fully settled in the early of year 2013.
	Equity Investment in NQ Guotai
	The Group uses equity method to account for equity investment in NQ Guotai and fair value method to account for investments conducted by NQ Guotai. The fair value of investments made by NQ Guotai is determined by various approaches, including the income approach, market approach and the replacement cost approach, as appropriate. The major qualitative and quantitative inputs in valuation of fair value are development stage, work force, customer and vendor relationships, risk factors, financial conditions including historical financial statements and future financial forecasts, comparable companies in the same industry, time of investments to balance sheet date and price of recent investment by new investors. The fair value of the equity investments conducted by NQ Guotai represents level 3 valuations as the assumptions used in valuing the investments were not directly or indirectly observable in the market and involved a lot of management judgment. See Note 8 – “Equity Investments”.
	Non-recurring
	The Group measured certain financial assets, including equity method investments excluding investment in the investment company and cost method investments, at fair value on a nonrecurring basis and recorded these assets at fair value only when impairment is recognized. The Group’s non-financial assets, such as intangible assets, goodwill and property and equipment, would be measured at fair value on a nonrecurring basis and recorded these assets at fair value only when other-than-temporary impairment is recognized. These assets are considered Level 3 assets because the Group used unobservable inputs to determine their fair values
	The following are other financial instruments not measured at fair value in the balance sheets but for which the fair value is estimated for disclosure purposes.
	Short-term receivables and payables
	Accounts receivable and certain other current assets are financial assets with carrying values that approximate to fair value due to their short term nature. Short-term accounts payable and accrued liabilities are financial liabilities with carrying values that approximate fair value due to their short term nature. The Group estimated fair values of other short-term receivables and payables using the discounted cash flow method. The Company classifies the valuation technique as Level 3 of fair value measurement, as it uses estimated cash flow input which is unobservable in the market.
	Long-term payables and Other non-current assets
	Long-term payables and other non-current assets are financial liabilities and assets with carrying values that approximate fair value due to the change in fair value after considering the discount rate, being immaterial.

	2007 Share Plan and 2011 Share Plan
	On June 7, 2007, the Board of Directors of the Company passed a resolution to adopt the 2007 Global Share Plan (the “2007 Share Plan”) that provides for the granting of options to selected employees, directors and non-employee consultants to acquire common shares of the Company at exercise prices determined by the Board or the administrator appointed by the Board at the time of grant. Upon this resolution, the Board of Directors and shareholders authorized and reserved 10,000,000 common shares for the issuance under the 2007 Share Plan. On December 15, 2007, the Board of Directors passed a resolution to increase the number of shares reserved for issuance under the Plan to 21,176,471 common shares. On April 26, 2010, December 15, 2010 and February 28, 2011, the Board of Director of the Company passed resolutions to increase the number of shares reserved for issuance under the 2007 Share Plan to 26,415,442, 36,415,442 and 44,415,442 common shares, respectively. As of December 31, 2013, no awards are available for future grants.
	On March 15, 2011, the Board of Directors of the Company passed a resolution to adopt the 2011 Share Incentive Plan (the “2011 Share Plan”) that provides for the granting of options, restricted shares or restricted share units (collectively the “Awards”) to selected employees, directors, and non-employee consultants to acquire common shares of the Company. The exercise prices of the options are determined by the Board or the administrator appointed by the Board at the time of grant. Upon this resolution, the Board of Directors and shareholders authorized and reserved 13,000,000 common shares for the issuance under the 2011 Share Plan. The Company may grant Awards that entitle holders to up to 13 million shares (the “Authorized Grant Pool”). For every year thereafter, starting in 2012, the Company may add up to a certain number of shares to the Authorized Grant Pool (the “Annual Increase Amount”). The Annual Increase Amount is defined as the number of shares underlying all awards granted in the previous year that are still outstanding. As of December 31, 2011, 2012 and 2013, Awards available for future grants amounted to 2,970,500 and 5,944,731 and 2,954,350 commons shares respectively.
	Vesting of Awards
	All Company’s Awards will be exercisable only if Award holder continues employment or non-employee consultant provides service through each vesting date. Granted Awards follow any of the following vesting schedules below:
	Schedule I:
	1. 25% of the Awards will become vested on the first-year anniversary of the vesting commencement date;
	2. 1/48 of the Awards will become vested each month on the same day of the month as the vesting commencement date over a three-year period thereafter, until fully vested (4 years) or vesting terminates pursuant to terms of the 2007 Share Plan or 2011 Share Plan
	Schedule II:
	1. 100% of the Awards will become vested on the first-year anniversary of the vesting commencement date.
	Schedule III:
	1. 100% of the Awards will become vested when granted and not subject to any vesting terms.
	Schedule IV:
	1. 1/16 of the Awards will become vested each calendar quarter on the same day of the quarter as the vesting commencement date over a four-year period thereafter, until fully vested (4 years) or vesting terminates pursuant to terms of 2007 Share Plan.
	Schedule V:
	1. 1/24 of the Awards will become vested each calendar quarter on the same day of the quarter as the vesting commencement date over a six-year period thereafter, until fully vested (6 years) or vesting terminates pursuant to terms of 2007 Share Plan.
	Schedule VI:
	1. 25% of the Awards will become vested when granted and not subject to any vesting terms;
	2. 3/48 of the Awards will become vested each quarter on the same day of the quarter as the vesting commencement date over a three-year period thereafter, until fully vested (3 years) or vesting terminates pursuant to terms of 2011 Share Plan.
	Schedule VII:

	Schedule VIII:
	1. 25% of the Awards will become vested on the first-year anniversary of the vesting commencement date;
	2. 3/48 of the Awards will become vested each quarter on the same day of the quarter as the vesting commencement date over a three-year period thereafter, until fully vested (4 years) or vesting terminates pursuant to terms of 2011 Share Plan.
	Significant modification
	On November 8, 2010, the Board of Directors approved a modification to the terms of all options issued to 69 non-employee consultants to accelerate their vesting on that date. The modification was at the sole discretion of the Company and was carried out based on the fulfillment of service commitment made by these non-employee consultants. As a result of this modification, the Company recognized all remaining unrecognized compensation expense of US$2,452 related to the modified options for the year ended December 31, 2010.
	On February 28, 2011, the Board of Directors approved another modification to the terms of all options issued to 51 employees and 70 non-employee consultants to accelerate their vesting on that date. The modification was at the sole discretion of the Company and was carried out to incentivize the employees and based on the fulfillment of service commitment made by non-employee consultants, respectively. As a result of this modification, the Company recognized all remaining unrecognized compensation expense of US$285 related to modified options for the year ended December 31, 2011.
	On October 28, 2013, the Group entered into Amendment of Service Agreement with each external consultant to clarify their duties and penalties of default of Service Agreement. Upon the execution of such amendment, a performance commitment was established. As such, 1,451,680 unvested options and 4,850,635 unvested restricted shares in total to non-employee consultants were remeasured based on the fair value of respective awards on modification date. There are no incremental expenses related to this amendment.
	Other Share Awards
	a.	Share Awards to Co-Chief Executive Officer
	On January 8, 2012, the Group granted 10, 000,000 restricted shares of the Company to the Co-Chief Executive Officer (“Co-CEO”) of the Company. Of the 10,000,000 restricted shares, 6,000,000 restricted shares will vest over four years provided that he continues his employment with the Company. 25% of the 6,000,000 restricted shares will vest on the first-year anniversary of the employment commencement date and 1/48 of 6,000,000 restricted shares will vest each month over a three-year period thereafter. The remaining 4,000,000 restricted shares are subject to the achievement of either specific performance or market conditions for each of the next four years. The value of the restricted shares under the market or performance conditions was calculated based on their grant date fair values without considering the possibility that the service conditions or performance conditions will be achieved. As all the criteria for establishing grant date were met, the fair value of share-based compensation being recognized for these restricted shares was measured on January 8, 2012.
	For the 6,000,000 restricted shares that are subject only to the service condition, the related compensation expenses are being recognized using graded vesting method over the next four years. For the 4,000,000 restricted shares subject to either performance or market condition, the Company has first determined whether or not it was probable that the performance condition would be achieved. The fair value of the restricted shares calculated reflecting the market condition represents the minimum amount that is recognized as compensation cost assuming the requisite service is completed, even if the performance or market condition is not met.
	Pursuant to the employment agreement among NQ US, the Company and Co-CEO, the Company shall establish a new entity, NQ Global and shall issue 15% equity interest in NQ Global (“NQ Global Shares”) to the Co-CEO for a nominal value. The NQ Global Shares have an embedded put option where the Co-CEO has the right in his sole discretion, to require the Company to purchase a portion or all of NQ Global Shares owned by the Co-CEO (“Put Option”) at their fair market value on the exercise date. While the NQ Global Shares are fully vested upon their issuance, the Put Option will vest and become exercisable at the rate of 25% of the underlying shares upon each of the first four annual anniversaries of the employment commencement date. All the key terms and conditions were substantially agreed among the counterparties in February 2012 and therefore the grant date was established at that time. Since these NQ Global Shares were fully vested upon grant, the entire compensation expenses of US$451 were recognized on the grant date. The fair value of 15% equity interest in NQ Global is determined based on the income approach.
	On May 8, 2012, the Company modified the employment agreement among NQ US, the Company and the Co-CEO so that Co-CEO gave up his 15% equity interest in NQ Global and the related Put Option. Concurrently, the Company granted 9,000,000 restricted shares of the Company to the Co-CEO. Of the 9,000,000 restricted shares, 3,500,000 restricted shares are subject to a four-year service condition and the remaining 5,500,000 restricted shares are subject to the achievement of either specific performance or market conditions for each of the next four years. This was determined to be a modification to the original award granted to the Co-CEO. As a result, the incremental compensation expense of US$14,019, calculated as the excess of the fair value of the 9,000,000 restricted shares over the fair value of 15% equity interest in NQ Global on the modification date, was recognized from May 8, 2012 over the vesting period.
	As a result, the Company totally granted 19,000,000 restricted shares, considering the 10,000,000 restricted shares that the Company granted to the Co-CEO on January 8, 2012. Of the 19,000,000 restricted shares, 9,500,000 restricted shares are subject to a four-year service condition and the remaining 9,500,000 are subject to the either specific performance or market conditions for the next four years.
	The restricted shares of 9,500,000 subject to either specific performance or market conditions that become vested and non-forfeitable are up to 11,875,000 since they shall be determined on the last day of each fiscal year based on the percentage achievement of fiscal year performance goal. As of December 31, 2012, the Company determines that it is not probable that the performance conditions will be achieved for all the 9,500,000 restricted shares. As a result, the related compensation expense calculated based on the fair value on the grant date that reflects the market condition is recognized over the requisite service period using graded vesting method.
	Of the 9,500,000 restricted shares that are subject to the achievement of either specific performance or market conditions, 2,521,755 restricted shares were granted and vested on December 31, 2012, since the market condition for the year ended December 31, 2012 was achieved.
	On April 3, 2013, an amendment was signed among the Company, the NQ US and the Co-CEO, under which the market conditions were removed and the performance conditions was revised for the restricted shares that will vest in 2013 through 2015. This was determined to be a modification to the awards granted to the Co-CEO. There was no incremental compensation related to this modification, based on the difference between the fair value of the modified awards and the fair value of the original award immediately before the modification.
	Compensation expense of US$12,330 and US$6,428 were recognized relating to the 19,000,000 restricted shares for the year ended December 31, 2012 and 2013. Total unrecognized compensation expenses relating to these restricted shares amounted to US$4,706 as of December 31, 2013 and are expected to be recognized over a weighted-average period of 2.0 years as of December 31, 2013.

	For restricted shares granted in connection with the above acquisition activities, the value of the restricted shares is determined on the fair value of the acquisition date, on which all criteria for establishing the grant dates were satisfied. The value of restricted shares subject to service condition attached is recognized as the compensation expense using the graded-vesting method. The value of restricted shares with performance conditions attached is recognized as compensation expense using the graded-vesting method only when the achievement of performance conditions becomes probable. The Company performs assessment of probability on a quarterly basis and recognizes the compensation expenses on a prospective basis.

The aggregate intrinsic value in the table above represents the difference between the Company’s closing stock price on the last trading day of each year end and the exercise price. The total intrinsic values of options exercised during the years ended December 31, 2011, 2012 and 2013 were US$15,108, US$2,707 and US$7,136, respectively.
Management is responsible for determining the fair value of options granted to employees and non-employees and considered a number of factors including valuations. As disclosed in Notes 2(x), the Group’s share-based compensation cost is measured at the fair value of the award as calculated under the Binomial option-pricing models.
Assumptions used in the option-pricing model are presented below:
Granted to Employees		2011		2012	2013
Average risk-free interest rate		2.70%-4.20%		1.04%-3.00%	2.26%-3.16%
Exercise Multiple		2.0-3.0		2.2-2.8	2.0-2.8
Expected Forfeiture Rate		0%-2%		0%-5%	0%-7%
Expected option life		10 years		10 years	10 years

Dividend yield		0%		0%	0%
Share price		$0.80-2.19		$1.25-2.14	$1.21-4.53
Granted to Non-Employees		2011		2012	2013
Average risk-free interest rate		2.70%		2.24%-2.60%	2.26%-3.06%
Exercise Multiple		N/a		N/a	N/a
Expected Forfeiture Rate		—		—	—
Expected option life		10 years		9-10 years	8-10 years

Dividend yield		0%		0%	0%
Share price		$0.95-1.07		$1.21-2.13	$1.21-4.36
The Company estimated the risk free rates based on the yield to maturity of China government bonds denominated in US$ as at the option respective valuation dates. Exercise multiple is estimated as the ratio of fair value of stock over the exercise price as at the time the option is exercised, based on a consideration of research study regarding exercise pattern based on historical statistical data. Multiples of 2 to 3 were used for the options granted in valuation analysis. Life of the stock options is the contract life of the option. Based on the option agreements, the contract life of the option is 10 years from respective grant date. The expected volatility at the date of grant date and each option valuation date was estimated based on historical volatility of comparable companies for the period before the grant date with length commensurate with the expected term of the options. The Group has no history or expectation of paying dividends on its common shares. The Group estimated the fair value of the common shares using the income approach or market approach when valuing options granted before IPO while closing prices of the Company’s publicly traded shares were adopted when valuing options granted in post-IPO period.
The Company recognizes share-based compensation expense net of an estimated forfeiture rate and therefore only recognizes compensation cost for those shares expected to vest over the service period of the award. The estimation of the forfeiture rate is based primarily upon historical experience of employee turnover. The Group estimated the forfeiture rate to be 12.5% and 0% for share options granted to employees and senior management, respectively, as of December 31, 2013.
The Company recorded options related share-based compensation expenses of US$9,874, US$8,266 and US$8,536 for the years ended December 31, 2011, 2012 and 2013, respectively, attributed using graded-vesting method over the requisite service period. Total fair values of options vested are US$2,736, US$7,438 and US$5,961, for employees and US$833, US$546 and US$851, for non-employee consultants during the years ended December 31, 2011, 2012 and 2013, respectively. Weighted average grant date fair values per option during the years are US$1.1021, US$0.9066 and US$0.9051 for the years ended December 31, 2011, 2012 and 2013, respectively. The Group did not capitalize any of the share-based compensation expenses as part of the cost of any asset for the years ended December 31, 2011, 2012 and 2013.
As of December 31, 2013, there was US$9,168 unrecognized compensation expenses related to non-vested options. The expenses are expected to be recognized over a weighted-average period of 2.4 years.

TAXATION [Abstract]	'
Taxation	'
	15. TAXATION
	(a) Transition from PRC Business Tax to PRC Value Added Tax
	A Pilot Program for transition from the imposition of Business Tax to the imposition of VAT for revenues from certain industries was launched in Shanghai on January 1, 2012. Effective from September 1, 2012, the Pilot Program was expanded from Shanghai to eight other cities and provinces in China, including Beijing. Advertising revenue and other revenue from technology development and services became subject to the VAT on and after September 1, 2012 at a rate of 6%.
	(b) Business Tax and related Surcharges
	Prior to the Pilot Program, the Group’s operations in the PRC are subject to 3% or 5% Business Tax. Related surcharges are 12% of Business Tax. Both Business Tax and the related surcharges are recognized when the revenue is earned.
	After the Pilot Program, the Group’s mobile value added services operated by domestic subsidiaries remain subject to 3% Business Tax and the related surcharges.
	(c) Value Added Tax
	Prior to the Pilot Program, in addition to Business Tax and related surcharges, the Group was subject to VAT at a rate of 17% for enterprise mobility revenue derived from hardware sales.
	After the Pilot Program, the Group’s advertising revenue and revenues from technology development and services are subject to 6% VAT. The Group’s enterprise mobility revenues derived from hardware sales remain subject to VAT at a rate of 17%.
	(d) Withholding income tax
	The Enterprise Income Tax Law also imposes a withholding income tax of 10% on dividends distributed by a FIE to its immediate holding company outside of China. A lower withholding income tax rate of 5% is applied if the FIE’s immediate holding company is registered in Hong Kong or other jurisdictions that have a tax treaty arrangement with China. Such withholding income tax was exempted under the previous income tax law. On February 22, 2008, the Ministry of Finance and State Administration of Taxation jointly issued a circular which stated that for FIEs, all profits accumulated up to December 31, 2007 are exempted from withholding tax when they are distributed to foreign investors. Based on the interpretation of the current tax laws, management believes that the Company and all its non-PRC subsidiaries are not considered as a “resident enterprise” in China for corporate income tax purposes, but it cannot be certain that the relevant PRC tax authorities will agree with this determination.
	As of December 31, 2012 and 2013, the Company did not record any withholding tax on the retained earnings of its FIEs in the PRC as the Company intends to reinvest all earnings in China since 2008 to further expand its business in China, and its FIEs do not intend to declare dividends on the retained earnings made since 2008 to their immediate foreign holding companies.
	(e) Income taxes
	Cayman Islands
	Under the common tax laws of the Cayman Islands, the Company is not subject to tax on its income, or capital gains, in addition, upon payment of dividends by the Company to its shareholders, no Cayman Islands withholding tax will be imposed.
	Hong Kong
	Entities incorporated in Hong Kong are subject to Hong Kong profit tax at a rate at 16.5% since the beginning of 2008.
	United States
	In the year of 2013, NQ US applies cost-plus method to compute the taxable income and is subject to a graduated federal corporate income tax rate. The mark-up rate applied to total cost under cost-plus method and federal corporate income tax rate for the year ended December 31, 2013 were 6% and 34%, respectively. NQ US paid income taxes of approximately US$199 for the year ended December 31, 2013.
	Mainland China
	On March 16, 2007, the National People’s Congress adopted the new Corporate Income Tax Law (the “New CIT Law”), which became effective from January 1, 2008 and replaced the previous separate income tax laws for domestic enterprises and foreign-invested enterprises by adopting a uniform income tax rate of 25%. Preferential tax treatments continue to be granted to entities that are qualified as “high and new technology enterprises strongly supported by the State”, or conducted business in encouraged sectors. An enterprise qualified as a “high and new technology enterprise” is entitled to a preferential income tax rate of 15%.
	On August 3, 2005, the State Bureau of Taxation adopted the preferential tax treatments for the entities obtained the software enterprise qualification, after the New CIT Law became effective, entities qualifying software enterprise continued to be entitled to 2 years tax exemption from the first profitable year followed by 3 years preferential tax rate of 12.5%.
	In addition, under the New CIT Law, dividends, interests, rent, royalties and gains on transfers of property payable by a foreign-invested enterprise in the PRC to its foreign investor who is a non-resident enterprise will be subject to withholding tax, unless such non-resident enterprise’s jurisdiction of incorporation has a tax treaty with the PRC that provides for a reduced rate of withholding tax. The withholding tax rate is 5% for the parent company in Hong Kong if the parent company is the beneficial owner of the dividend and approved by the PRC tax authority to enjoy the preferential tax benefit. The withholding tax rate is 10% for the parent company incorporated in other countries which do not have any tax treaty with the PRC. Such a withholding tax imposed on the dividend income received from the Company’s PRC entities will reduce the Company’s net income. On February 22, 2008, the Ministry of Finance and State Tax Bureau jointly issued a circular which stated that for foreign invested enterprises, all profits accumulated up to December 31, 2007 are exempted from withholding tax when they are distributed to foreign investors.
	The Company’s PRC entities CIT rate was as follows:
	Beijing Technology was qualified as a high and new technology enterprise under the New CIT Law and it has successfully renewed this status in late 2011 which enabled it enjoying preferential income tax treatment for another 3 years up to 2013. Accordingly, it was subject to a rate of 7.5% from 2008 to 2010, and a rate of 15% thereafter so long as it continues to qualify as a high and new technology enterprise. The CIT rate was approved by Beijing Haidian District State Tax Bureau as a transitional treatment to allow the Beijing Technology to continue to enjoy its unexpired tax holiday provided by the previous income tax laws and rules. Beijing Technology paid CIT of US$16, US$75 and US$201 for the years ended December 31, 2011, 2012 and 2013, respectively.
	NQ Beijing, FL Mobile and NQ Tongzhou were qualified as a software enterprise under the New CIT Law, which were entitled to enjoy preferential income tax treatment of income tax exemption for the first two years when it became profitable, followed by three years preferential income tax rate of 12.5%. In 2013, NQ Beijing was approved to enjoy preferential income tax treatment of income tax exemption for one more year. Accordingly, NQ Beijing was subject to zero income tax rate from 2012 to 2013, and a rate of 12.5% from 2014 to 2016; FL Mobile was subject to zero income tax rate from 2012 to 2013, and a rate of 12.5% from 2014 to 2016. NQ Tongzhou was subject to zero income tax rate from 2013 to 2014, and a rate of 12.5% from 2015 to 2017. The CIT rates were approved by Beijing Haidian District State Tax Bureau, Beijing Dongcheng District State Tax Bureau and Beijing Tongzhou District State Tax Bureau respectively as a software enterprise to allow NQ Beijing, FL Mobile and NQ Tongzhou to enjoy its tax holiday provided by previous income tax laws and rules.
	NationSky was subject to the prevailing income tax rate of 25% on taxable income for the years ended 2011. NationSky and Wanpu century were qualified as high and new technology enterprises under the New CIT Law, which were entitled to enjoy income tax rate of 15% for the years from 2012 to 2014 and 2013 to 2015 respectively. Fanyue was qualified as high and new technology enterprises, which enable it to enjoy the preferential income tax rate of 15% in 2013.
	NQ Shenzhen and Yinlong were qualified as software enterprises under the New CIT Law, which were entitled to enjoy preferential income tax treatment of income tax exemption for the first two years when it became profitable, followed by three years preferential income tax rate of 12.5% from the first profitable year. They did not become profitable as of December 31, 2013.
	Red, Tianya, and Ruifeng were subject to a prevailing income tax rate of 25%. The New CIT Law also provides that an enterprise established under the laws of foreign countries or regions but whose “de facto management body” is located in the PRC be treated as a resident enterprise for PRC tax purposes and consequently be subject to the PRC income tax at the rate of 25% for its global income. The Implementation Rules of the New CIT Law merely define the location of the “de facto management body” as “the place where the exercising, in substance, of the overall management and control of the production and business operation, personnel, accounting, properties, etc., of a non-PRC company is located.” Based on a review of surrounding facts and circumstances, the Company does not believe that it is likely that its operations outside the PRC should be considered a resident enterprise for PRC income tax purposes. However, due to limited guidance and implementation history of the New CIT Law, should the Company be treated as a resident enterprise for PRC income tax purposes, the Company will be subject to PRC income tax on worldwide income at a uniform income tax rate of 25% retroactive to January 1, 2008.
	For the years ended December 31, 2011, 2012 and 2013, the Company did not have any material interest or penalties associated with tax positions nor did the Company have any significant unrecognized uncertain tax positions.

CONVERTIBLE DEBTS [Abstract]	'
Convertible Debts	'
	17. CONVERTIBLE DEBTS
	In October 2013, the Company issued US $172.5 million in aggregate principle amount of 4.00% Convertible Senior Notes due October 15, 2018 (the “Notes”) at par. The Notes may be converted, under certain circumstances, based on an initial conversion rate of 39.0472 American depository shares (“ADSs”) per US$1,000 principal amount of the Notes (which represents an initial conversion price of US$25.61 per ADS).
	The Notes are the Company’s general unsecured obligations that rank (1) senior in right of payment to all of the Company’s indebtedness that is expressly subordinated in right of payment to the Notes, (2) equal in right of payment with all of the Company’s liabilities that are not so subordinated, (3) effectively junior to any of the Company’s secured indebtedness to the extent of the value of the assets securing such indebtedness, and (4) structurally junior to all indebtedness and other liabilities of the Company’s subsidiaries and consolidated affiliated entities.
	The main terms of the Notes and corresponding assessment of the accounting treatments are summarized as follows:
	Redemption at the option of the holders. The holders may require the Company to repurchase all or a portion of the Notes for cash on October 15, 2016, or upon a Fundamental Change (As defined in Exhibit 2.6), at a repurchase price equal to 100% of the principal amount, plus accrued and unpaid interest, if any, to but excluding the repurchase date or fundamental change purchase date.
	In accordance with ASC 815-10-15-83, the redemption option exercisable on October 15, 2016 or upon a Fundamental Change meets the definition of a derivative instrument. However, it does not meet the requirement of bifurcation because it is considered clearly and closely related to its debt host in accordance with ASC 815-15-25-1, since the Notes were issued at par and will be settled at par plus accrued and unpaid interest if the debt holders elect to exercise the redemption option. Additionally, the Notes holder would recover all of their initial investment and there are no interest rate scenarios under which the redemption option would double the Notes holder’s initial rate of return.
	Redemption at the option of the Company. On or after October 20, 2016, the Company may redeem all or portion of the Debts for cash, at its option, if the last reported sale price of its ADSs has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period ending on, and including, the trading day immediately prior to the date the Company provided the notices of redemption (the “embedded redemption feature”). The Company must provide notice of redemption not less than 30 nor more than 60 calendar days before the redemption date to the trustee, the paying agent and each holder of the debts. The redemption price will equal 100% of the principal amount, plus accrued and unpaid interest, to, but excluding the redemption date.
	In accordance with ASC 815-10-15-83, the embedded redemption feature (“Call option”) meets the definition of a derivative instrument. Since the exercisability of the call option is contingent upon the stock price other than interest risk and credit risk, the call option meets the requirement of bifurcation in accordance with ASC 815-15-25-41,
	The Company continues to believe bifurcation of the contingent call option is acceptable under ASC 815-15. However, considering the SEC comment letters dated January 15, 2014 and March 3, 2014 as well as subsequent discussion with the SEC Staff on this matter, the Company agreed that an acceptable alternative treatment is not to bifurcate the contingent call option and understood this treatment is a prevailing practice. The Company believes bifurcation of the call option adds additional complexities to its financial reporting without adding significant value to the readers of its financial statements. To enhance comparability, the Company has decided to change the method of its accounting for the embedded call option and will not separately account for the embedded call option in its 2013 financial statements.
	Conversion. The conversion rate is initially 39.0472 ADSs per $1,000 principal amount, which represents a conversion price of approximately $25.61 per ADS, subject to adjustment under certain circumstances for issuance of share dividends, issuance of rights or warrants, subdivisions or combination of capital stock, indebtedness, or assets, cash dividends and issue tender or exchange offers. The Notes are convertible at any time prior to maturity. In addition, upon a Make-Whole Fundamental Change (As defined in Exhibit 2.6), the Company will, under certain circumstances, increase the applicable conversion rate for a holder that elects to convert its Notes in connection with such a Make-Whole Fundamental Change.
	In accordance with ASC 815-10-15-83, the conversion option meets the definition of a derivative instrument. However, bifurcation of conversion option from the debt host is not required because the conversion option meets ASC 815 scope exception, as the conversion option is considered indexed to the Company’s own stock and classified in stockholders’ equity.
	There was no beneficial conversion feature attributable to the Notes as the set conversion price of the Notes was greater than the fair value of the common share price at the date of issuance.
	The debt holders have the option to convert the Notes to shares upon the Make-Whole Fundamental Change. The number of shares issuable upon conversion in connection with the Make-Whole Fundamental Change will be increased. The Company will assess the contingent beneficial conversion feature at the time when the Make-Whole Fundamental Change occurs.
	Accounting for Convertible Senior Notes and issuance cost are summarized as follows:
	The Company has accounted for the Notes in accordance with ASC 470-20, as a single instrument as a non-current liability. The Notes are initially carried at the gross cash received at the issuance date.
	The net proceeds the Company received from the issuance of the Notes were US$166,395. The Company will pay cash interest at an annual rate of 4.00% on the Notes, payable semi-annually in arrears on April 15 and October 15 of each year, beginning on April 15, 2014.
	Debt issuance costs were US$ 6,834, which comprises of underwriter fees, professional fees paid to accounting and legal consultants and other miscellaneous expenses occurred specifically for the debts. Debt issuance costs are initially capitalized as deferred charges in other non-current assets and are amortized as interest expenses over the period of three years from the inception date of the Notes to the first redemption date, using the effective interest method.
	The interest expense included in the consolidated statements of operations is as follows:
		For the year ended December 31, 2013
		US$
	Interest expense at an annual rate of 4.00%		1,418
	Amortization of debt issuance costs		441
	Total interest expense		1,859
	As of October 15, 2014, the Company had accrued the additional interest of US$357 at the rate of 0.5% per annum, due to the Company’s failure to file on time.

Due to the foreign currency exchange remittance administrative procedures, a receivable of US$2,200 was recorded as other current assets as of December 31, 2010 and this receivable was subsequently paid off in January 2011.
	All Preferred Shares have a par value of US$0.0001 per share. The rights, preferences and privileges of the Preferred Shares are as follows:
	Conversion
	Each preferred share is convertible, at the option of the majority shareholders for each class with regarding to the conversion of each class, at any time after the date of issuance of such preferred shares into such number of common shares according to a conversion ratio determined by dividing the original issuance price by the applicable conversion price. Each share of Series A, Series B, Series C and Series C-1 Preferred Share is convertible into one common share and is subject to adjustments for certain events, including but not limited to share splits and combinations, common share dividends and distributions, reorganizations, mergers, consolidations, reclassifications, exchanges, and substitutions. The conversion price is also subject to adjustment in the event the Company issues additional common shares at a price per share that is less than such conversion price. In such case, the conversion price shall be reduced to adjust for dilution.
	Each preferred share is automatically be converted into common shares at the then effective applicable conversion price, upon (i) the closing of a Qualified IPO, or (ii) the written consent of holders of more than fifty percent (50%) of the outstanding Preferred Shares of each class with respect to conversion of each class. The Qualified IPO is defined as a firm commitment underwritten registered public offering by acceptable to the holders of a majority of the then outstanding holders of a majority of the then outstanding Preferred Shares holders, for each class voting as a separate class, and to the Company with aggregate offering proceeds (before deduction of fees, commissions or expenses) to the Company and selling shareholders, if any, of not less than US$40,000 (or any cash proceeds of other currency of equivalent value) that reflects a market valuation of the Company of not less than US$200,000 and the price per share of no less than US$1.00.
	As of December 31, 2010, the Company had reserved 114,637,272 shares of common shares for the conversion of the preferred shares based on the respective conversion ratio of each class.
	Liquidation Preference
	In the event of any liquidation, dissolution or winding up of the Company, either voluntarily or involuntarily, the holders of preferred shares shall be entitled to receive an amount per share equal to 100% of the original purchase price plus all dividends accrued, or declared and unpaid. If the assets and funds distributed among the holders are insufficient to permit the payment of the full preferential amounts, then the holders of Series C Preferred Shares and Series C-1 Preferred Shares shall be entitled to be paid first out of the assets of the Company available for distribution among the shareholders, prior and in preference to any payment on all other series of preferred shares and Common Shares, followed in sequence by Series B Preferred Shares, Series A Preferred Shares, and Common Shares. After payment of the full amounts from above, the remaining assets of the Company available for distribution shall be distributed ratably among the holders of Preferred Shares and Common Shares in proportion to the number of outstanding shares held by each such holder on an as converted basis, provided that the amount of distribution or payment to each holder of Series A Preferred Shares shall not exceed 500% of the original purchase price of Series A Preferred Shares.
	In the event of any consolidation, amalgamation, merger, any other reorganization including a sale or acquisition of the Common Shares, or other transaction involving the Company in which its shareholders do not retain a majority of the voting power in the surviving entity, a sale of all or substantially all the Company’s assets, termination of or making any unilateral amendments to any of the VIE agreements, and the exclusive licensing of all or substantially all of the Company’s intellectual property to a third party (“Liquidation Event”), any proceeds shall be distributed to the Preferred Share holders unless waived by majority of the Preferred Shareholders.
	Redemption
	Beginning on or after fourth anniversary following the issuance of the Series B Preferred Shares, at the option of a holder of the Series B Preferred Shares, the Company shall redeem all of the outstanding Series B Preferred Shares held by the requesting holder at a redemption price equal to the original purchase price of Series B Preferred Shares x (1.10) N plus all declared but unpaid dividends. “N” means a fraction the numerator of which is the number of calendar days between the original Series B issue date and the date when the Series B Preferred Shares are redeemed and the denominator of which is 365. In association of the issuance of Series C Preferred Share, the redemption commencement date for Series B Preferred Shares has been changed to be the fourth anniversary following the issuance of the Series C Preferred Shares. This is deemed to be a wealth transfer between different classes of Preferred Shares and there is no accounting treatment.
	Beginning on or after fourth anniversary following the issuance of the Series C Preferred Shares, at the option of a holder of the Series C or Series C-1 Preferred Shares, the Company shall redeem all of the outstanding Series C or Series C-1 Preferred Shares held by the requesting holder at a redemption price equal to the original purchase price of Series C or Series C-1 Preferred Shares plus all declared but unpaid dividends.
	Dividends
	The Series C Preferred Shares shall rank pari passu with Series C-1 Preferred Shares in terms of rights to receive dividends and distributions from the Company, followed in sequence by Series B Preferred Shares, Series A Preferred Shares, and Common Shares. Each Preferred Shares holder is entitled to receive, on an annual basis, preferential, non-cumulative dividends at the rate equal to the greater of (i) 8% of the original issue price and (ii) the dividend that would be paid with respect to the Common Shares into which the Preferred Shares could be converted. Dividends shall not accumulate or accrue unless declared. No dividends on preferred and Common Shares have been declared since the inception through December 31, 2010 and up to the date of completion of IPO on May 5, 2011.
	Voting Rights
	The holders of Preferred Shares have voting rights equal to the number of Common Shares then issuable upon their conversion into Common Shares. Such holders of the Preferred Shares are entitled to vote on such matters at any meeting of the Company.
	The Company classified the Preferred Shares in the mezzanine section of the consolidated balance sheets. The Company also recorded accretion on the Series B Preferred Shares and Series C Preferred Shares to the redemption value from respective issuance dates to respective earliest redemption dates. For the years ended December 31, 2010, 2011 and 2012, such accretion amounted to US$1,529, US$533 and US$0 for Series B Preferred Shares, respectively, and US$4,US$2 and US$0, respectively, for Series C Preferred Shares against additional paid-in capital.
	The Company has determined that conversion and redemption features embedded in the redeemable convertible preferred shares are not required to be bifurcated and accounted for as a derivative.
	No beneficial conversion feature charge was recognized for the issuance of Series A Preferred Shares, Series B Preferred Shares and Series C Preferred Shares as the estimated fair value of the Common Shares is less than the conversion price on the dates of issuance and at the time of the aforementioned conversion adjustment assessment.
	For Series C-1 Preferred Shares, as the estimated fair value of the Common Shares is higher than the conversion price on the dates of issuance and at the time of the abovementioned conversion adjustment assessment, the excess of estimated fair value of the Common Shares and the conversion price is deemed to be the beneficial conversion feature and was allocated to additional paid-in capital from the total proceeds. Subsequently, it was immediately recognized as a deemed dividend against additional paid-in capital with the corresponding increase to the carrying value of the Series C-1 Preferred Shares because the Series C-1 Preferred Shares are convertible upon issuance for the year ended December 31, 2010.
	Conversion to Common Shares upon Completion of IPO
	Upon the completion of the IPO on May 5, 2011, each Preferred Share was automatically converted into one Class B common share. As a result, 114,637,272 Class B common shares were issued, and the balance of Preferred Shares was transferred to common shares and additional paid-in capital as of May 5, 2011. There were no preferred shares outstanding as of December 31, 2011, 2012 and 2013.

(filed on November 5, 2013); Martin v. NQ Mobile, Inc., et al., Civil Action No. 13 CIV 8125 (S.D.N.Y.) (filed on November 14, 2013). On December 2, 2013, another putative shareholder class action suit against the Company and certain current and former directors and officers of the Company, Hsieh v. NQ Mobile, Inc., et al., Civil Action No. 13 CIV 1048 (E.D. Tex.), was filed in the United States District Court for the Eastern District of Texas. On January 6, 2014, Kostuk v. NQ Mobile, Inc., et al., Civil Action No. 13 CIV 12712 (D. Mass.), was voluntarily dismissed by the plaintiff. On April 9, 2014, the United States District Court for the Southern District of New York consolidated the six putative shareholder class action suits filed in that court under the caption, In re NQ Mobile, Inc. Securities Litigation, Civil Action No. 13 CIV 7608 (S.D.N.Y.), and appointed a lead plaintiff. On May 13, 2014, Hsieh v. NQ Mobile, Inc., et al., Civil Action No. 13 CIV 1048 (E.D. Tex.), was transferred from the U.S. District Court for the Eastern District of Texas to the U.S. District Court for the Southern District of New York and was accepted by the Southern District of New York as related to the consolidated putative shareholder class action, In re NQ Mobile, Inc. Securities Litigation.
	On July 21, 2014, the lead plaintiff in In re NQ Mobile, Inc. Securities Litigation filed a Consolidated Class Action Complaint (the “Consolidated Complaint”) against the Company, the co-chief executive officers Henry Yu Lin and Omar Sharif Khan, chief operating officer Vincent Wenyong Shi, former chief financial officer Suhai Ji, former chief financial officer Kian Bin Teo, and the former auditors PricewaterhouseCoopers Zhong Tian LLP and its affiliate, PricewaterhouseCoopers International Limited.
	The putative class actions contain similar factual allegations, allege virtually the same class period, are brought against the same or similar defendants, and advance the same or similar theories of liability. These actions seek to represent a class of persons who allegedly suffered damages as a result of their trading activities related to the Company’s ADSs from May 4 or 5, 2011 to October 23 or 24, 2013. The complaints allege that various press releases, financial statements and other related disclosures made by the Company during the alleged class period contained material misstatements and omissions, in violation of the federal securities laws, and that such press releases, financial statements and other related disclosures artificially inflated the value of the Company’s ADSs. The complaints generally seek monetary damages on behalf of the class of persons who allegedly suffered losses during the class period.
	The management cannot yet estimate the range of reasonably possible loss because these litigations remain at their preliminary stages. The Group believes that it does not have sufficient evidence to anticipate the outcome of the litigations and also the possible contingent losses. Therefore, no accruals for contingent loss were recorded in the consolidated financial statements as of December 31, 2013.

Restricted Net Assets	'
	26. RESTRICTED NET ASSETS
	Relevant PRC statutory laws and regulations permit payments of dividends by the Company’s PRC subsidiaries, VIE and VIE’s subsidiaries only from their retained earnings, if any, determined in accordance with PRC GAAP. In addition, the Company’s subsidiary, VIE and VIE’s subsidiaries in China are required to make annual appropriations of 10% of after-tax profit to general reserve fund or statutory surplus fund. As a result of these PRC laws and regulations, the Company’s PRC subsidiary, VIE and VIE’s subsidiaries are restricted in their abilities to transfer net assets to the Company in the form of dividends, loans or advances. Total restricted net assets of the Company’s PRC subsidiary, VIE and VIE’s subsidiaries were US$79,033 or 23.7% of the Company’s total consolidated net assets as of December 31, 2013. Even though the Company currently does not require any such dividends, loans or advances from the PRC subsidiaries, VIE and VIE’s subsidiaries for working capital and other funding purposes, the Company may in the future require additional cash resources from its PRC subsidiaries and VIEs due to changes in business conditions, to fund future acquisitions and developments, or merely declare and pay dividends to or distributions to the Company’s shareholders. There were no undistributed retained earnings in associated companies in the consolidated retained earnings due to losses incurred by them.

Significant_Accounting_Policie1

Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2013
SIGNIFICANT ACCOUNTING POLICIES [Abstract]	'
Basis of presentation and consolidation	'
	(a) Basis of presentation and consolidation
	The accompanying consolidated financial statements include the financial statements of the Company, its subsidiaries, its VIE for which the Company is the ultimate primary beneficiary, and the VIE’s subsidiaries.
	These consolidated financial statements have been prepared on a historical cost basis to reflect the financial position and results of operations of the Company, its subsidiaries, VIEs and VIEs’ subsidiaries in accordance with the accounting principles generally accepted in the United States of America (“US GAAP”).
	Commencing January 1, 2013, due to the expansion of the Company’s business and diversification of revenue streams in 2013, revenue presentation was reclassified into categories of (i) mobile value added services, which includes original revenue stream of consumer mobile security and mobile games; (ii) enterprise mobility; (iii) advertising services; and (iv) other services. The comparative figures, for the years ended December 31, 2011 and 2012, have been reclassified to conform to the current presentation.
	Subsidiaries are those entities in which the Company, directly or indirectly, controls more than one half of the voting power; or has the power to govern the financial and operating policies, to appoint or remove the majority of the members of the board of directors, or to cast a majority of votes at the meeting of directors.
	A VIE is an entity in which the Company, or its subsidiary, through contractual arrangements, bears the risks of, and enjoys the rewards normally associated with, ownership of the entity, and therefore, the Company or its subsidiary is the primary beneficiary of the entity.
	All significant inter-company transactions and balances have been eliminated upon consolidation.
Business Combinations	'
	(b) Business Combinations
	The Company accounts for its business combinations using the purchase method of accounting in accordance with ASC 805: Business Combinations. The purchase method accounting requires that the consideration transferred to be allocated to the assets, including separately identifiable assets and liabilities the Company acquired based on their estimated fair values. The consideration transferred of an acquisition is measured as the aggregate of the fair values at the date of exchange of the assets given, liabilities incurred, and equity instruments issued as well as the contingent considerations and all contractual contingencies as of the acquisition date. The costs directly attributable to the acquisition are expensed as incurred. Identifiable assets, liabilities and contingent liabilities acquired or assumed are measured separately at their fair value as of the acquisition date, irrespective of the extent of any non-controlling interests. The excess of (i) the total of cost of acquisition, fair value of the non-controlling interests and acquisition date fair value of any previously held equity interest in the acquiree over (ii) the fair value of the identifiable net assets of the acquiree, is recorded as goodwill. If the cost of acquisition is less than the fair value of the net assets of the subsidiary acquired, the difference is recognized directly in the consolidated statements of comprehensive income.
	The determination and allocation of fair values to the identifiable assets acquired, liabilities assumed and non-controlling interests is based on various assumptions and valuation methodologies requiring considerable management judgment. The most significant variables in these valuations are discount rates, terminal values, the number of years on which to base the cash flow projections, as well as the assumptions and estimates used to determine the cash inflows and outflows. The Company determines discount rates to be used based on the risks inherent in the related activity’s current business model and industry comparisons. Terminal values are based on the expected life of assets, forecasted life cycle and forecasted cash flows over that period.
	In a business combination achieved in stages, the Company re-measures its previously held equity interest in the acquiree at its acquisition-date fair value and recognizes the resulting gain or loss in earnings.
Use of estimates	'
	(c) Use of estimates
	The preparation of these consolidated financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses and the related disclosures of contingent assets and liabilities. Management makes its estimates based on historical experience and on various other assumptions it believes to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities. Actual results could differ from those estimates. Significant accounting estimates reflected in the Company’s consolidated financial statements mainly include the allowance for doubtful accounts, the valuation allowance of deferred tax assets, the estimated useful lives of long-lived assets, the impairment assessment of long-lived assets and equity investments, the valuation and recognition of share-based compensation, and goodwill and fair value of identifiable assets and liabilities acquired through business combination.
Cash and cash equivalents	'
	(d) Cash and cash equivalents
	Cash and cash equivalents represent cash on hand, demand deposits, and other short-term highly liquid investments placed with banks, which have original maturities of three months or less and are readily convertible to known amounts of cash.
Term deposits	'
	(e) Term deposits
	Term deposits represent time deposits placed with banks with original maturities of more than three months and equal or less than one year. Interest earned is recorded as interest income in the consolidated statements of comprehensive income during the period.
Short-term investments	'
	(f) Short-term investments
	Short term investments refer to the available-for-sale investments made in financial instruments with guaranteed return of principal upon maturity with a variable interest rate indexed to the performance of underlying assets.
	In accordance with ASC 825, for investments in financial instruments with a variable interest rate indexed to the performance of underlying assets, the Company elected the fair value method at the date of initial recognition and carried these investments subsequently at fair value. Changes in the fair value are reflected in the consolidated statements of comprehensive income. The carrying amount of investments approximates their fair value. To estimate fair value, the Company refers to the quoted rate of return provided by banks at the end of each period using discounted cash flow method. The Company classifies the valuation techniques that use these inputs as Level 2 of fair value measurements. Since the Group did not intend to hold the financial instruments over one year, they were classified as short-term investments.
Allowance for doubtful accounts	'
	(g) Allowance for doubtful accounts
	An allowance for doubtful accounts is recorded in the period in which a loss is determined to be probable based on an assessment of specific evidence indicating doubtful collection, historical experience, account balance aging and prevailing economic conditions. Accounts receivable balances are written off after all collection efforts have been exhausted and the potential for recovery is considered remote. The following table presents movement of the allowance for doubtful accounts:
		Balance at		Charged to		Write-Offs			Balance
		Beginning		Expenses		Net of			at End
		of Year				Recoveries			of Year
		US$		US$		US$			US$
	Allowance for doubtful accounts
	2011		315		321		—			636
	2012		636		459		—			1,095
	2013		1,095		3,027		(204	)		3,918
Inventory	'
	(h) Inventory
	Inventories, consisting of products and devices available for sale, are accounted for using first in first out method, and are valued at the lower of cost or market. This valuation requires the Company to make judgments, based on currently available information, about the likely method of disposition, such as through sales to individual customers, returns to product vendors, or liquidations, and expected recoverable values of each disposition category.
Equity investments	'
	(i) Equity investments
	The Company’s equity investments are comprised of privately-held companies and limited partnerships. The Company uses the cost method to account for investments in shares that are not common stock or in-substance common stock, or investments in shares that are common stock or in-substance common stock, but over which the Company does not have significant influence. The Company uses the equity method to account for common stock equivalent equity investments in private-held companies over which the Company has significant influence but does not own a majority equity interest or otherwise control. The Company also uses the equity method to account for investments in limited partnerships unless the Company’s equity interest is so minor that the Company may have virtually no influence over the partnerships operating and financial policies.
	Cost method investments
	In accordance with ASC subtopic 325-20 (“ASC 325-20”), Investments-Other: Cost Method Investments, the Company carries the cost method investments at cost and only adjusts for other-than-temporary declines in fair value and distributions of earnings. Management regularly evaluates the impairment of the cost method investments based on performance and financial position of the investee as well as other evidence of market value. Such evaluation includes, but is not limited to, reviewing the investee’s cash position, recent financing, projected and historical financial performance, cash flow forecasts and financing needs. An impairment loss is recognized in the consolidated statements of comprehensive income equal to the excess of the investment’s cost over its fair value at the balance sheet date of the reporting period for which the assessment is made. The fair value would then become the new cost basis of investment.
	Equity method investments
	In accordance with ASC subtopic 323-10 (“ASC 323-10”), Investments-Equity Method and Joint Ventures: Overall, the Company initially records its equity method investments at cost and any excess of the cost of the investment over the proportional fair value of the underlying tangible and intangible assets and liabilities of the investee is recognized as equity method goodwill, which is included in the equity method investment on the consolidated balance sheets. The Company subsequently adjusts the carrying amount of the investment to recognize the Company’s proportionate share of each equity investee’s net income or loss into consolidated statements of comprehensive income after the date of acquisition. The Company will discontinue applying equity method if an investment (and additional financial supports to the investee, if any) has been reduced to zero.
	Sales of equity interests of an investee by the company is accounted for as gains or losses equal to the difference at the time of sale between selling price and carrying amount of the equity interests sold.
	Impairment for equity investments
	The Group assesses its equity investments for other-than-temporary impairment by considering factors including, but not limited to, current economic and market conditions, operating performance of the companies, including current earnings trends and undiscounted cash flows, and other company-specific information. The fair value determination, particularly for investments in privately-held companies, requires significant judgment to determine appropriate estimates and assumptions. Changes in these estimates and assumptions could affect the calculation of the fair value of the investments and determination of whether any identified impairment is other-than-temporary.
Property and equipment, net	'
	(j) Property and equipment, net
	Property and equipment are stated at cost less accumulated depreciation and impairment. Depreciation is provided on a straight-line basis over the following estimated useful lives:
		Estimated useful lives of the assets
	Computer equipment		3 years
	Leasehold improvements		Shorter of lease terms and estimated useful lives
	Electronic equipment		3 years
	Office equipment		5 years
	Motor vehicles		5 years
	Expenditure for repairs and maintenance is expensed as incurred. The gain or loss on disposal of property and equipment is the difference between the net sales proceeds and the carrying amount of the relevant assets and is recognized in the consolidated statements of comprehensive income.
Goodwill	'
	(k) Goodwill
	Goodwill is the excess of the consideration transferred over the fair value of the acquired assets and assumed liabilities in a business combination.
	The Company tests goodwill for impairment at the reporting unit level on an annual basis as of December 31, and between annual tests when an event occurs or circumstances change that could indicate that the asset might be impaired. Commencing in September 2011, in accordance with the FASB revised guidance on “Testing of Goodwill for Impairment,” a company first has the option to assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If the company decides, as a result of its qualitative assessment, that it is more-likely-than- not that the fair value of a reporting unit is less than its carrying amount, the quantitative impairment test is mandatory. Otherwise, no further testing is required. The quantitative impairment test consists of a two-step goodwill impairment test. The first step compares the fair value of each reporting unit to its carrying amount. If the fair value of each reporting unit exceeds its carrying amount, goodwill is not considered to be impaired and the second step will not be required. If the carrying amount of a reporting unit exceeds its fair value, the second step compares the implied fair value of goodwill to the carrying value of a reporting unit’s goodwill. The implied fair value of goodwill is determined in a manner similar to accounting for a business combination with the allocation of the assessed fair value determined in the first step to the assets and liabilities of the reporting unit. The excess of the fair value of the reporting unit over the amounts assigned to the assets and liabilities is the implied fair value of goodwill. This allocation process is only performed for purposes of evaluating goodwill impairment and does not result in an entry to adjust the value of any assets or liabilities. An impairment loss is recognized for any excess in the carrying value of goodwill over the implied fair value of goodwill.
	Application of a goodwill impairment test requires significant management judgment, including the identification of reporting units, assigning assets and liabilities to reporting units, assigning goodwill to reporting units, and determining the fair value of each reporting unit. The judgment in estimating the fair value of reporting units includes estimating future cash flows, determining appropriate discount rates and making other assumptions. Changes in these estimates and assumptions could materially affect the determination of fair value for each reporting unit.
Intangible Assets	'
	(l) Intangible Assets
	Intangible assets, comprising computer software, domain name use right, revenue sharing agreements, customer relationship, non-compete agreements, user base, technology, game and other finite-lived intangible assets, which are separable from the fixed assets, are stated at cost less accumulated amortization. Amortization is computed using the straight-line method over the estimated useful lives of the assets.
Impairment of long-lived assets	'
	(m) Impairment of long-lived assets
	The carrying amounts of long-lived assets other than goodwill are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is evaluated by a comparison of the carrying amount of assets to future undiscounted net cash flows expected to be generated by the assets. Such assets are considered to be impaired if the sum of the expected undiscounted cash flow is less than carrying amount of the assets. The impairment to be recognized is measured by the amount by which the carrying amounts of the assets exceed the fair value of the assets. No impairment of long-lived assets was recognized for any of the periods presented.
Convertible Debts	'
	(n) Convertible Debts
	In accordance with ASC subtopic 470-20, the convertible debts are initially carried at the principal amount of the convertible debts, adjusted by the fair value of any embedded put or call option. Debt premium or discounts, which are the differences between the carrying value and the principal amount of convertible debts at the issuance date, together with related debts issuance cost, are subsequently amortized using effective interest method as adjustments to interest expense from the debt issuance date to its first redemption date. Convertible debts are classified as a current liability if they are or will be callable by the Company or puttable by the debt holders within one year from the balance sheet date, even though liquidation may not be expected within that period.
Functional currency and foreign currency translation	'
	(o) Functional currency and foreign currency translation
	The Group’s reporting currency is the U.S. dollar (“US$”). The functional currency of the Company, NQ HK and NQ US is US$, while the functional currency of the Company’s PRC subsidiaries, VIE and VIE’s subsidiaries is RMB. In the consolidated financial statements, the financial information of the Company’s subsidiaries, VIE and VIE’s subsidiaries has been translated into US$. Assets and liabilities are translated at the exchange rates on the balance sheet date, equity amounts are translated at historical exchange rates, and revenues, expenses, gains and losses are translated using the average rate for the year. Translation adjustments are reported as foreign currency translation adjustments and are shown as a separate component of other comprehensive income or loss in the statements of shareholders’ equity and comprehensive income.
	Transactions denominated in currencies other than the functional currency are translated into prevailing functional currency at the exchange rates prevailing at the dates of the transactions. Monetary assets and liabilities denominated in foreign currencies are translated into the functional currency using the applicable exchange rates at the balance sheet dates. The resulting exchange differences are included in the consolidated statements of comprehensive income.
Revenue recognition	'
	(p) Revenue recognition
	The Group recognizes revenue when persuasive evidence of an arrangement exists, delivery has occurred and/or service has been performed, the price is fixed or determinable and collection is reasonably assured.
	In accordance with ASC 605-45, the Company adopts net presentation method for its revenue, under which revenues are net of business tax, related surcharges and value added tax.
	Revenues presented in the consolidated statements of comprehensive income include revenues from mobile value added services that are comprised of consumer mobile security and mobile games, advertising services, enterprise mobility and other services.
	Mobile Value Added Services Revenues
	Consumer mobile security revenues
	Consumer mobile security revenues are derived principally from providing premium mobile security and productivity services to end users. The basic functions of security and productivity services, including anti-virus, anti-malware, anti-spam, privacy protection, data backup and recovery are free of charge. The customers are charged for updating the anti-virus database on a pay-per-use basis or paying a fee to subscribe to the premium security and productivity services including continuous update of anti-virus database, continuous update of the semantics of anti-spam, and advanced privacy protection on a monthly, quarterly, semi-annually or annually basis. The Group recognizes revenue for premium services considered to be software-related (e.g., mobile security services) in accordance with industry specific accounting guidance for software and software-related transactions. For premium services where the customer does not take possession of fully-functioning software (e.g., mobile productivity services), the Group recognizes revenue pursuant to ASC 605, Revenue Recognition. Provided collectability is probable, revenue is recognized over the usage period which is the same for software-related services and services where software is incidental to the provision of the services. Basic functions and customer support are provided to end users free of charge, whether they subscribe to services or not. Customer arrangements may include premium mobile security and productivity services which are multiple elements. Revenue on arrangements that include multiple elements is allocated to each element based on the relative fair value of each element. Fair value is generally determined by vendor-specific- objective-evidence (“VSOE”). For all the periods presented, the usage period for the elements in arrangements that include multiple elements is the same. No allocation was performed as there is no impact from the allocation on revenue recognized.
	Revenue for pay-per-use services is recognized on a per-use basis when the update is made. Proceeds from sale of subscription services are deferred when received and revenue for the subscription services is recognized on a straight-line basis over the estimated service period provided all revenue recognition criteria have been met.
	The payment channels include wireless carriers and service providers, independent distributors of prepaid cards, and third-party payment processors.
	Wireless carriers and service providers. The Group, via service providers, cooperates with wireless carriers to provide consumer mobile security services to the customers. In China, service providers have the exclusive licenses to contract with wireless carriers in offering consumer mobile security services to the end users and they are mainly responsible for assisting in the billing of consumer mobile security services. Wireless carriers are mainly responsible for billing, collection and customer support relating to the end users. Under certain circumstances, the Group itself is a service provider and contract directly with wireless carriers.
	Fees paid for premium service are charged to the customers’ telephone bills and shared between us and wireless carriers. The sharing percentage is fixed and determined by wireless carriers. The Group does not enter into arrangements directly with the wireless carriers except when the Group acts as a service provider and the wireless carriers are not acting as an agent for us in the transactions. Therefore, the revenue recognized is net of the amounts retained by the wireless carriers.
	The Group recognizes and report consumer mobile security services revenues on a gross basis based on service providers’ portion of the billings as the Group has the primary responsibility for fulfillment and acceptability of the consumer mobile security services and are considered a principal in the transactions. The amounts attributed to services providers’ share are determined pursuant to the arrangements between services providers and us and are recognized as costs of revenues.
	To recognize consumer mobile security services revenues, the Group relies on wireless carriers and service providers to provide us with the billing confirmations for the amount of services they have billed to their mobile customers. At the end of each reporting period, when the wireless carriers or service providers are yet to provide us the monthly billing confirmations, the Group uses information generated from internal system as well as the historical data to estimate the amounts of collectable consumer mobile security services fees and to recognize revenue. Historically, there have been no significant adjustments to the revenue estimates.
	Prepaid cards. The Group sells prepaid cards to customers through independent distributors. The customers can use the prepaid cards to subscribe to the premium services. Once the customers activate the premium services using the prepaid cards, the Group starts to recognize revenues on a straight-line basis over the service period. The unused cash balances remaining in users’ accounts are recorded as a liability in deferred revenue. While the Group has primary responsibility for fulfillment and acceptability, the Group does not have control of, and generally do not know, the ultimate selling price of the prepaid cards sold by the distributors, and therefore, net proceeds from the distributors form the basis of revenue recognition.
	Third-party payment processors. The customers can also subscribe to premium services directly through the Company’s website and the billings are handled by third-party payment processors. Under these circumstances, the Group has the primary responsibility for fulfillment and acceptability and recognizes the revenue on a gross basis. The amounts attributed to third-party payment processors are recognized as costs of revenue.
	Mobile games revenues
	Mobile game revenues are derived principally from game operations for both third-party developed mobile games and self-developed mobile games and game licensing of self-developed mobile games to other third-party game operators.
	Mobile game operations. The Group generates mobile games revenues from operating and publishing mobile games developed by third parties and itself. The Group enters into exclusive or joint operation agreements with developers for licensed mobile game applications. The Group distributes the games on Apple’s App Store, Android platforms, FL Mobile’s platforms and other channels (collectively, “Platforms”). Game players can download the free-to-play games and pay to acquire virtual currency which can be redeemed in the game for in-game virtual items.
	The Group sells both consumable and durable virtual goods in games. Consumable goods are items that are used up one-time, while durable goods are items accessible to the user over an extended period of time. For games under joint operation, the Group recognizes revenue from the sales of both consumable goods and durable goods at once when the virtual items are delivered. For games under exclusive operations, the Group recognizes revenue from the sales of consumable goods when the goods are used up. The Group recognizes revenue from the sales of durable goods ratably over the estimated average playing period of paying users.
	The Groups estimates the playing periods of paying users based on available data obtained since September 2012. On a quarterly basis, the Groups determines the estimated average playing period for paying players on a game by game basis, beginning at the time of a payer’s first purchase in that game and ending on a date when that paying player is no longer playing the game. The Group then calculates the average of the time periods from the first purchase date to the date the last player is expected to cease playing the game for each game player to determine the total average playing period for that game.
	The Group determines that a paying player will cease playing a game once the Inactive Period has occurred. The Group defines the Inactive Period as the time period after which if a paying player has not logged onto a game, the possibility that he/she will continue to play the game in the future is very low. To determine the Inactive Period, the Group regularly analyzes the paying players’ activities on games to determine when the paying players stop playing the games. For the players who have not logged onto a game for 50 days as of the period end, the Group deems them inactive players. For the players who have not logged onto a game for less than 50 days as of the period end, the Group deems that they will cease to play the game after 90 days from the last date when they logged onto the game before the period end.
	Currently estimated average playing periods of the mobile games are three months, based on current available game player information. The Group regularly reassesses these estimates and may revise such estimates in the future as additional game data becomes available and if and when future data indicates a change in playing patterns or behaviors.
	Pursuant to agreements signed between the Group and game developers and between the Group and Platforms, revenues from the sale of game currency to be used for the purchase of virtual items are shared among the Group, game developers and Platforms for third-party developed games and between the Group and Platforms for self-developed games, based on a pre-agreed ratio for each game.
	The determination of whether to record these revenues using gross or net method is based on an assessment of various factors. The primary factors are whether the Group is acting as the principal in offering services to the game players or as an agent in the transaction, and the specific requirements of each agreement.
	For third-party developed games under exclusive operation agreements and self-developed games, the Group recognizes revenue based on the gross amount billed to customers (i.e., inclusive of the amount retained by Platforms and the amounts paid to game developers under revenue-sharing arrangements if any), because the Group is able to determine pricing for the virtual items sold and is the primary obligor to the customers. The amount paid to Platforms and game developers are recorded as cost of services.
	For third-party developed games under joint operation agreements, the game developer is considered the primary obligor to the customers and has latitude in establishing price. The Group accounts for such sales on a net basis by recognizing the commission it retains from each sale (i.e., revenue net of the amount retained by Platforms and the amounts paid to game developers under revenue-sharing arrangements).
	To determine whether the Platform plays a role of primary obligor or an agent, the Group has considered ASC 605-45-45 and concluded that the Platform is an agent in the sale of in-game virtual items to the customers because it 1) is not responsible for the fulfillment of in-game virtual items and does not take overall responsibility of the services provided to the customers, 2) does not have pricing latitude and only receives a fixed commission, 3) does not have inventory risk, 4) does not change the virtual items sold or determine specifications of the game or the virtual items sold, and 5) does not have credit risk. In the case of self-developed games and third-party developed games under exclusive operation by the Group, Platforms are the agents of the Group. In the case of third-party developed games under joint operation, Platforms are the agents of the game developers.
	Mobile game licensing. The Group licenses its self-developed games to other third-party game operators and generally receives revenue in forms of initial license fees, non-refundable minimum guarantee, monthly revenue-based fees under revenue-sharing arrangement or a combination. The initial license fee is generally a fixed amount and recognized ratably over the term of the license. The non-refundable minimum guarantee is generally a fixed amount and recognized once the fees are collected. The revenue-based fees under revenue-sharing arrangement are generally equal to a fixed percentage of the revenues generated by the game operators from the sale of virtual items and are recognized when the game operators provide the Group the monthly billing confirmation.
	Advertising Revenues
	Advertising revenues are derived principally from promotion of third-parties’ applications, games or services over a particular period of time, through a variety of patterns, which are classified into online advertising services and offline advertising services.
	Online advertising revenues. The Group promotes third-parties’ games and applications through NQ security applications and interest-based online community applications in a variety of forms including but not limited to offer-walls, push-notification, and content integrations. Advertising fees are generally charged to advertisers on the cost per action (“CPA”) basis. The desired actions to be performed include but are not limited to activation, download, click, registration or opt-ins, which are determined by the advertisers. The revenues are generally recognized when the end users activate the applications, register accounts or deliver their opt-ins.
	The Group also provides advertising services by embedding the advertisement in applications developed by third-party content providers. The Group signs agreements with advertisers and content providers separately. The determination of whether to record these revenues using gross or net method is based on an assessment of various factors. The primary factors are whether the Group is acting as the principal in offering services to advertisers or as an agent in the transaction, and the specific requirements of each agreement. After considering the Company’s obligations and risks, latitude in establishing price, determination of service specifications and etc., the Group concludes that the Group is the primary obligor in the contracts with advertisers. The fees are charged to advertisers on the CPA basis. The revenues are recognized by us on a gross basis pursuant to ASC 605-45, including payments to content providers. The advertising fees paid to the third-party content providers are recognized as costs of services.
	Moreover, the Group provides advertisement placements on the Company’s websites and interest-based communities. The Group enters into pay-for-time (“CPT”) contracts with advertisers, under which the fixed price and advertising services are established upfront and charged ratably over the contractual period of display.
	Offline pre-installation revenues. The Group provides with the pre-installation services to promote various applications in mobile phones. The revenues are recognized when the end users activate the applications or become active users within certain periods, pursuant to the contracts.
	Enterprise Mobility Revenues
	Enterprise mobility revenues are derived principally from hardware sales to enterprise users, technology and software development, and commission income shared from mobile network operators, all of which are provided on a stand-alone basis in the year of 2013.
	The revenue from sale of hardware is recognized upon the time of delivery. Hardware is considered delivered to customers once customers acknowledge the receipt of the hardware delivered and the title and risk of loss have been transferred. For most of the hardware sales, these criteria are met at the time customers sign off the delivery notes.
	The Group recognizes the revenue from technology and software development upon the delivery and acceptance by customers of the standard proprietary software or tailored enterprise software, which involves significant production, modification, or customization. These software arrangements generally include the right to postcontract customer support (“PCS”). The Group recognizes the technology and software development revenues immediately after the Group delivers the software since PCS is assessed insignificant after considering the facts of (i) no additional charges are incurred for PCS; (ii) all PCS are normally for a period of 6 months to 1 year; (iii) the estimated cost for such services is insignificant based on historical records; and (iv) the Group does not offer upgrades or enhancements to the software during PCS period and these services are expected to continue to be infrequent. The Group adopts completed-contract method to account for revenues from technology and software development, given the substantive acceptance terms in arrangements and short duration of development.
	Commission income is derived from bringing enterprise users to the mobile network operators and is determined based on fixed percentages of actual charges to the enterprise users as agreed with the mobile operators. Commission incomes are recognized in the month in which the service is provided to the enterprise users. For the amount of revenues to be recognized, the Group firstly estimates the amount of service fee and recognizes revenue based on the fixed commission rates as stipulated on the contract that multiply the estimated customer charges. When the Group later receives the statements of actual charge issued by the mobile network operators, the Group records a true-up adjustment. Based on the historical experience, there had not been any material adjustments incurred.
	Other Services Revenues
	Other services revenues are derived principally from providing technology development and training services. The Group recognizes these revenues when performance is completed.
Cost of revenues	'
	(q) Cost of revenues
	Cost of revenues primarily consists of customer acquisition cost paid to third party business partners based on number of end users referred by them, which are expensed when earned by third party business partners, fees paid to the handset makers and promotion agents for them to preload the Group’s software and fees paid to or retained by SPs and third party payment processors for their services relating to the billing of the Group’s consumer mobile security revenues. Cost of revenues also includes the hardware procurement cost for enterprise mobility business, as well as fees paid to third-party content providers for advertising services and mobile game operations. Staff costs of those departments directly involved in providing mobile value added services, enterprise mobility and advertising services, as well as other services are also included in cost of revenues.
Marketing and Advertising costs	'
	(r) Marketing and Advertising costs
	Marketing and Advertising costs consist primarily of costs for the promotion of corporate image and product marketing. The Group expensed all marketing and advertising costs as incurred. Marketing and advertising costs for the years ended December 31, 2011, 2012 and 2013 are US$2,929, US$8,546 and US$13,318, respectively.
Research and development	'
	(s) Research and development
	Research and development related expenses consist primarily of payroll-related expenses incurred for new product development and product enhancements. The Group expenses all costs incurred for the development of mobile security and productivity software, technology and software for enterprise customers, and technology of mobile platforms when incurred prior to the establishment of technological feasibility. Once the software has reached technological feasibility with a proven ability to operate in the market, all subsequent software development costs shall be capitalized until that software is marketed. The amount of costs qualifying for capitalization has been immaterial and, as a result, the Group did not capitalize any research and development costs for the years ended December 31, 2011, 2012 and 2013.
Operating lease	'
	(t) Operating lease
	Leases where substantially all the risks and rewards of ownership of the assets remain with the leasing company are accounted for as operating leases. Payments made under operating leases are charged to the consolidated statements of comprehensive income on a straight line basis over the lease periods.
Gain on change of interest in an associate	'
	(u) Gain on change of interest in an associate
	The gain on change of interest in an associate represents the difference at the time of change of interest in an associate between the transfer price and carrying amount of the interest transferred. The Group recognized a gain of US$943 from the change of equity interest in FL Mobile in the year ended December 31, 2012. See Note 4 – “Business Combination”. No sale of interest in an associate occurred in the year ended December 31, 2013.
Government Grant	'
	(v) Government Grant
	Government grant is recorded as a liability in deferred revenue when receive upfront, and recognize as other income or reduction of related expense in the period when (i) all of the conditions attached to the subsidy are satisfied or it is not subject to future return or reimbursement, and (ii) the subsidies have been received or become receivable with reasonable assurance. The Group recorded subsidies from the PRC government of US$155, US$40 and US$761 in other income for the years ended December 31, 2011, 2012 and 2013, respectively.
Employee benefits	'
	(w) Employee benefits
	Full-time employees of the Group in mainland China are entitled to staff welfare benefits including medical care, welfare subsidies, unemployment insurance and pension benefits through a PRC government-mandated multi-employer defined contribution plan. The Group is required to accrue for these benefits based on certain percentages of the employees’ salaries. The Group is required to make contributions to the plans out of the amounts accrued. The PRC government is responsible for the medical benefits and the pension liability to be paid to these employees and the Group’s obligations are limited to the amounts contributed.
	The Group recorded employee benefit expenses of US$1,250, US$1,845 and US$4,393 for the years ended December 31, 2011, 2012 and 2013, respectively.
Share-based compensation	'
	(x) Share-based compensation
	The Group grants share options and restricted shares to its selected employees, directors and non-employee consultants. Awards granted to employees with service conditions attached are measured at the grant date fair value and are recognized as an expense using graded vesting method, net of estimated forfeitures, over the requisite service period, which is generally the vesting period. The estimate of forfeitures will be adjusted over the requisite service period to the extent that actual forfeitures differ, or are expected to differ, from such estimates. Changes in estimated forfeitures will be recognized through a cumulative catch-up adjustment in the period of change and will also impact the amount of share-based compensation expense to be recognized in future periods.
	Awards granted to employees with performance conditions attached are measured at fair value on the grant date and are recognized as the compensation expenses in the period and thereafter when the performance goal becomes probable to achieve.
	Awards granted to employees with market conditions attached are measured at fair value on the grant date and are recognized as the compensation expenses over the estimated requisite service period, regardless of whether the market condition has been satisfied if the requisite service period is fulfilled.
	Awards granted to non-employees are measured at fair value at the earlier of the commitment date or the date the services are completed, and are recognized using graded vesting method over the period the service is provided.
	Binomial option-pricing models are adopted to measure the value of awards at each grant date or measurement date. The determination of fair value is affected by the share price as well as assumptions relating to a number of complex and subjective variables, including but not limited to the expected share price volatility, actual and projected employee and non-employee share option exercise behavior, risk-free interest rates and expected dividends. The use of the option-pricing model requires extensive actual employee and non-employee exercise behavior data for the relative probability estimation purpose, and a number of complex assumptions.
Non-controlling interest	'
	(y) Non-controlling interest
	Non-controlling interest represents the equity interest in subsidiaries that is not attributable, either directly or indirectly, to the Company’s shares in such subsidiaries. The non-controlling interest is presented in the consolidated balance sheets, separately from equity attributable to the shareholders of the Company. Non-controlling interest in the results of the Company is presented on the face of the consolidated statements of comprehensive income as an allocation of the total profit or loss for the periods between non-controlling shareholders and the shareholders of the Company.
Treasury Shares	'
	(z) Treasury Shares
	The Company accounted for those shares repurchased as treasury shares at cost in accordance with ASC 505-30, and the treasury shares acquired are shown separately in the shareholders’ equity as the Company has not yet decided on the ultimate disposition of those shares. If and when the Company cancels the treasure shares, the difference between the original issuance price and the repurchase price will be debited into additional paid-in-capital.
Income tax	'
	(aa) Income tax
	Current income tax is provided on the basis of income for financial reporting purpose, adjusted for income and expense items which are not assessable or deductible for income tax purpose, in accordance with the regulations of the relevant tax jurisdictions. Deferred income tax is accounted for using the liability approach which requires the recognition of income tax payable or refundable for the current year and deferred income tax liabilities and assets for the future tax consequences of events that have been recognized in the Group’s financial statements or tax returns. Deferred income tax is determined based on the differences between the financial reporting and tax basis of assets and liabilities and is measured using the currently enacted income tax rates and laws. The effect on deferred income tax assets and liabilities of a change in income tax rates is recognized in the consolidated statements of comprehensive income in the period when such changes are enacted. A valuation allowance is provided to reduce the carrying amounts of deferred income tax assets if it is considered more likely than not that a portion or all of the deferred income tax assets will not be realized.
Uncertain tax position	'
	(ab) Uncertain tax position
	The Group adopts a more likely than not threshold and a two-step approach for the tax position measurement and financial statement recognition. Under the two-step approach, the first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained, including resolution of related appeals or litigation process, if any. The second step is to measure the tax benefit as the largest amount that is more than 50% likely of being realized upon settlement.
Statutory reserve	'
	(ac) Statutory reserve
	The Company’s PRC subsidiaries, VIEs and the VIEs’ subsidiaries in China are required to make appropriations to certain non-distributable reserve funds.
	In accordance with the laws applicable to China’s Foreign Investment Enterprises, the Company’s subsidiaries that are foreign investment enterprises in China have to make appropriations from their after-tax profit (determined under the Accounting Standards for Business Enterprises promulgated by the Ministry of Finance of the People’s Republic of China (“PRC GAAP”)) to reserve funds including (i) general reserve fund; (ii) enterprise expansion fund; and (iii) staff bonus and welfare fund. The appropriation to the general reserve fund must be at least 10% of the after-tax profits calculated in accordance with PRC GAAP. Appropriation is not required if the reserve fund has reached 50% of the registered capital of the respective companies. Appropriations to the other two reserve funds are subject to discretion of respective companies.
	In accordance with China Company Laws, the Company’s PRC subsidiary, VIE and the VIE’s subsidiaries that are domestic companies, must make appropriations from their after-tax profit (determined under PRC GAAP) to non-distributable reserve funds including (i) statutory surplus funds; and (ii) discretionary surplus fund. The appropriation to the statutory surplus fund must be at least 10% of the after-tax profits calculated in accordance with PRC GAAP. Appropriation is not required if the surplus fund has reached 50% of the registered capital of the respective companies. Appropriation to the discretionary surplus fund is made at the discretion of respective companies.
	The use of the general reserve fund, statutory surplus fund and discretionary surplus fund are restricted to the offsetting of losses or increase of registered capital of the respective companies. These reserves are not allowed to be transferred to the Company in any forms of cash dividends, loans or advances, nor can they be distributed except under liquidation.
	For the years ended December 31, 2011, 2012 and 2013, profit appropriation to the general reserve fund and the statutory surplus fund (“statutory reserve”) totaled US$nil, US$2,938 and US$6,698, respectively, and there was no profit appropriation to other reserve funds for any of those years.
Earnings (loss) per share	'
	(ad) Earnings (loss) per share
	Basic earnings (loss) per share is computed using the weighted average number of common shares outstanding during the year. Diluted earnings (loss) per share is computed using the weighted average number of common shares and potential common shares outstanding during the period for options and restricted shares under treasury stock method and for convertible debts under if-convertible method, if dilutive. Potential common shares are not included in the denominator of the diluted earnings per share calculation when inclusion of such shares would be anti-dilutive, such as in a period in which a net loss is recorded. Earnings per share is computed on Class A common shares and Class B commons shares together, because both classes have the same dividend rights and the same participation rights in the Company’s undistributed earnings.
Related parties	'
	(ae) Related parties
	Parties are considered to be related if one party has the ability, directly or indirectly, to control the other party or exercise significant influence over the other party in making financial and operating decisions. Parties are also considered to be related if they are subject to common control or significant influence, such as a family member or relative, stockholder, or a related corporation.
Comprehensive income	'
	(af) Comprehensive income
	Comprehensive income is defined as the change in equity of the Group during a period from transactions and other events and circumstances excluding those resulting from investments by and distributions to shareholders. Accumulated other comprehensive income/(loss), as presented on the accompanying consolidated balance sheets, consists of cumulative foreign currency translation adjustment and unrealized gain or loss from available-for-sale investments.
Segment reporting	'
	(ag) Segment reporting
	Operating segments are defined as components of an enterprise engaging in business activities about which separate financial information is available that is evaluated regularly by the Group’s chief operating decision-maker (“CODM”), the Chief Executive Officer, in deciding how to allocate resources and assess performance.
	The Company’s organizational structure is based on a number of factors that the CODM uses to evaluate, view and run the Company’s business operations, which include, but are not limited to, customer base, homogeneity of products and technology. The Company’s operating segments are based on its organizational structure and information reviewed by the Company’s CODM to evaluate the operating segment results.
	The Company has determined that the business segments that constitute its primary reportable segments are consumer and enterprise. The consumer segment primarily consists of mobile value added services, which includes mobile security services and mobile games, advertising services and other services. The enterprise segment mainly consists of technology and software development services and hardware sales aggregated under enterprise mobility revenues.
	Before 2012, the Group principally engaged in consumer mobile security and other services and operated and managed this business as a single segment. In 2012, the Group expanded its business by the acquisition of NationSky in enterprise mobility services and the acquisition of FL Mobile and its subsidiary, Red, in mobile games and advertising services. In 2013, the Group enhanced its business in enterprise mobility services and advertising services by a series of acquisitions, and generates revenue from the operations of such businesses. See Note 4 – “Business Combination” for more details.
	The Company’s CODM separately reviewed key information of each of two operating segments consisting of consumer and enterprise, in order to optimize the management of operations. The Group’s reportable segments are strategic business units that offer different products and services. They are managed separately because each business requires different technology and marketing strategies as they are facing different group of customers.
Fair value measurement	'
	(ah) Fair value measurement
	The Company’s financial instruments include cash equivalents, term deposits, short-term investments, accounts receivable, certain other current and non-current assets, accounts payable, accrued expenses and other current liabilities and other non-current liabilities. For fair value measurement, U.S. GAAP establishes a three-tier hierarchy which prioritizes the inputs used in the valuation methodologies in measuring fair value:
	Level 1—observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets.
	Level 2—other inputs that are directly or indirectly observable in the marketplace.
	Level 3—unobservable inputs which are supported by little or no market activity.
	The fair value hierarchy also requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. See Note 12 – Fair value measurements.
Effect of Recent Accounting Pronouncements	'
	(ai) Effect of Recent Accounting Pronouncements
	In March of 2013, the FASB issued guidance on “Foreign Currency Matters, Parent’s accounting for the Cumulative Translation Adjustment upon Derecognition of Certain Subsidiaries or Groups of Assets within a Foreign Entity or of an Investment in a Foreign Entity.” The main provisions of these amendments are to require the parent to apply the guidance in Subtopic 830-30 to release any related cumulative translation adjustment into net income, when a reporting entity (parent) ceases to have a controlling financial interest in a subsidiary or group of assets that is a nonprofit activity or a business (other than a sale of in substance real estate or conveyance of oil and gas mineral rights) within a foreign entity. For an equity method investment that is a foreign entity, a pro rata portion of the cumulative translation adjustment should be released to net income upon a partial sale of such an equity method investment. Additionally, the amendments are also applied to business combination that result in an acquirer obtaining of control of an acquiree in which it held an equity interest immediately before the acquisition date (sometimes also referred to as a step-acquisition). The amendments are effective prospectively for fiscal year (and interim reporting periods within those years) beginning after December 15, 2013. The Group is currently evaluating the impact on its consolidated financial statement of adopting this guidance.
	In June 2013, the FASB issued guidance on “Financial Services-Investment Companies, Amendments to Scope, Measurement, and Disclosure Requirements.” The amendments change the approach to the investment company assessment in Topic 946, clarify the characteristics of an investment company, and provide comprehensive guidance for assessing whether an entity is an investment company. In addition, the amendments require an investment company to measure the non-controlling ownership interests in other investment companies at fair value rather than using the equity method of accounting. Moreover, the amendments require the additional disclosure about (a) the fact that the entity is an investment company and is applying the guidance in Topic 946, (b) information about changes, if any, in an entity’s status as an investment company, and (c) information about financial support provided or contractually required to be provided by an investment company to any of its investees. This amendment is effective for an entity’s interim and annual reporting periods in fiscal years that begin after December 15, 2013. The Group re-evaluated the characteristics of NQ Guotai, an equity investment company of the Group, in accordance with the updated guidance. Based on the assessment, NQ Guotai is still within the scope of investment companies and shall be accounted for using fair value approach.
	In July of 2013, the FASB issued guidance on “Income Taxes – Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists.” The amendments clarify that an unrecognized tax benefit, or a portion of an unrecognized tax benefit, should be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss, similar tax loss, or tax credit carryforward, except as noted in the following sentence. To the extent a net operating loss, similar tax loss, or tax credit carryforward is not available at the reporting date under the tax law of the applicable jurisdiction to settle an additional income taxes that would result from the disallowance of a tax position or the tax law of the applicable jurisdiction does not require the entity to use, and the entity does not intend to use, the deferred tax asset for such a purpose, then under this exception the unrecognized tax benefit is to be presented in the financial statements as a liability and should not be combined with (netted with) the deferred tax asset(s). The assessment of whether a deferred tax asset is “available” is based on the unrecognized tax benefit and deferred tax asset amounts that exist at the reporting date and should be made presuming disallowance of the tax position at the reporting date. The amendments are effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. The Group had evaluated that there was no impact on its consolidated financial statements of adopting this guidance.
	In May of 2014, the FASB issued Topic 606, “Revenue from Contracts with Customers”. This topic clarifies the principles for recognizing revenue and develops a common revenue standard for U.S. GAAP and IFRS. Simultaneously, this topic supersedes the revenue recognition requirements in Topic 605, Revenue Recognition, and most industry-specific guidance throughout the Industry Topics of the Codification. The core principle of the guidance requires an entity to recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. To achieve that core principle, an entity should apply the five steps: 1) identify the contract(s) with a customer; 2) identify the performance obligations in the contract; 3) determine the transaction price; 4) allocate the transaction price to the performance obligations in the contract; 5) recognize revenue when (or as) the entity satisfies a performance obligation. The amendments are effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. Early application is not permitted. This amendments shall be applied retrospectively either to each prior reporting periods or with the cumulative effect of initially applying this amendments recognized at the date of initial application. There is no impact on the consolidated financial statements for current reporting periods since early adoption is not permitted. The Group is in process of evaluating the cumulative effect on the consolidated financial statements of adopting this guidance so as to transit to the new revenue recognition guidance in the year of 2016.
	In June of 2014, the FASB issued guidance on “Stock Compensation –Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period”. The amendments clarify that a performance target that affects vesting and that could be achieved after the requisite service period should be treated as a performance condition. As such, the performance target should not be reflected in estimating the grant-date fair value of the award. No matter when the performance target becomes probable of being achieved, the compensation cost should be recognized in the period in which it becomes probable that the performance target will be achieved and should represent the compensation cost attributable to the period(s) for which the requisite service has already been rendered. The amendments are effective for annual periods and interim periods within those annual periods beginning after December 15, 2015. Earlier adoption is permitted. The Group had evaluated that there is no impact on the consolidated financial statements of adopting this guidance.
	As of October 15, 2014, the Financial Accounting Standards Board (“FASB”) has issued ASU No. 2013-01 through ASU 2014-15, which are not expected to have a material impact on the consolidated financial statements upon adoption.

For entities in profit in the year of 2013, the Group assesses the likelihood that the Group will recover the deferred tax assets from future taxable income. The total current deferred income tax assets were resulted from deductible advertising expenses, bad debt provision, government subsidy, accruals, accrued but unpaid payrolls and fixed asset depreciation from entities in profit in 2013.
