| Organization and nature of operations |
Xunlei Limited, previously known as Giganology Limited, (the “Company”) was incorporated under the law of the Cayman Islands (“Cayman”) as a limited liability company on February 3, 2005. The Company completed its initial public offering (“IPO”) on June 24, 2014 on the NASDAQ Global Market. Each American Depositary Shares (“ADSs”) of the Company represents five common shares. These consolidated financial statements include the financial statements of the Company, its subsidiaries, its variable interest entity (“VIE”) and the VIE’s subsidiaries (collectively referred to as the “Group”) as follows:
The Group engages primarily in the provision of premium downloading services to its members, online advertising services on its websites and mobile phone applications, sales of bandwidth, sales of cloud computing hardwares, platform for live streaming services, online game platforms for game developers and users, and other internet value added services. To comply with the PRC laws and regulations that prohibit or restrict foreign ownership of companies that provide online advertising services, operate online games, and hold Internet Content Provider (‘‘ICP’’) license, the Company conducts its business through Shenzhen Xunlei, its consolidated VIE. Through the various agreements enacted among the Company, Giganology Shenzhen, a wholly owned subsidiary of the Company, Shenzhen Xunlei and legal shareholders of Shenzhen Xunlei (the “Restructuring”), the Company received all of the economic benefits and residual interest and absorbed all of the risks and expected losses from Shenzhen Xunlei. Details of certain key agreements with the VIE are as follows: — Loan Agreements between Giganology Shenzhen and the shareholders of Shenzhen Xunlei— Giganology Shenzhen provided interest-free loans of RMB 9 million to the legal shareholders of Shenzhen Xunlei for them to make contributions as registered capital into Shenzhen Xunlei. The term of these agreements last for two years from the date it was signed, and will be automatically extended afterwards on a yearly basis until each legal shareholder of Shenzhen Xunlei has repaid the loans in its entirety in accordance with the loan agreement. The legal shareholders would not be allowed to transfer their interests in Shenzhen Xunlei without prior consent of Giganology Shenzhen. According to the loan agreements, the loans can only be repaid in the form of common shares of Shenzhen Xunlei. At any time during the term of the loan agreements, Giganology Shenzhen may, at their sole discretion, requires any of the legal shareholders of Shenzhen Xunlei to repay all or any portion of their outstanding loan under the agreement. Under a separate loan agreement between Giganology Shenzhen and Mr. Sean Shenglong Zou as a legal shareholder of Shenzhen Xunlei, Giganology Shenzhen made an additional interest-free loan of RMB20 million to Mr. Sean Shenglong Zou, the entire amount of which was contributed to the registered capital of Shenzhen Xunlei, increasing the registered capital of Shenzhen Xunlei to RMB 30 million. The term of this agreement last for two years from the date it was signed, and will be automatically extended afterwards on a yearly basis until Mr. Zou has repaid the loan in its entirety in accordance with the loan agreement. This loan will be deemed to be repaid when all equity interest held by the shareholders in Shenzhen Xunlei has been transferred to Giganology Shenzhen or its designated parties. At any time during the term of this loan agreement, the Company may, at their sole discretion, require all or any portion of the outstanding loan under the agreement to be repaid. — Business Operation Agreements between Giganology Shenzhen and Shenzhen Xunlei—Under these agreements, Giganology Shenzhen has the rights to direct the operating activities of Shenzhen Xunlei, including the appointment of senior management. The legal shareholders of Shenzhen Xunlei also transferred all their shareholders’ rights to Giganology Shenzhen. The term of this agreement will expire in 2016 and may be extended with Giganology Shenzhen’s confirmation prior to the expiration date. For instance, in May 2011, Shenzhen Xunlei sought and obtained consent from Giganology Shenzhen and the Company to increase its registered capital by RMB20 million and to revise its articles of association accordingly. This agreement expired on November 15, 2016 and has been extended to 2026. — Equity Pledge Agreement between Giganology Shenzhen and the legal shareholders of Shenzhen Xunlei—Under this agreement, the legal shareholders of Shenzhen Xunlei pledged all of their equity interests in Shenzhen Xunlei to Giganology Shenzhen. If Shenzhen Xunlei and/or its legal shareholders breach their contractual obligations under this agreement, Giganology Shenzhen, as pledgee, will be entitled to certain rights, including the right to sell the pledged equity interests. — Power of Attorney —Each legal shareholder of Shenzhen Xunlei appointed Giganology Shenzhen as its attorney-in-fact to exercise their shareholders’ rights in Shenzhen Xunlei, including shareholders’ voting rights. Each power of attorney will remain in force for 10 years unless the business operation agreement among Giganology Shenzhen, Shenzhen Xunlei and the legal shareholders of Shenzhen Xunlei is terminated in advance. This period may be extended at Giganology Shenzhen’s discretion. — Service Agreements between Giganology Shenzhen and Shenzhen Xunlei—Under various service agreements, Giganology Shenzhen will provide services including technical support, training, as well as consulting services to Shenzhen Xunlei in exchange for a service fee. These service agreements include the Exclusive Technology Support and Services Agreement, the Exclusive Technology Consulting and Training Agreement and the Software and Proprietary Technology License Contract. Giganology Shenzhen is entitled to service fees equal to 20%, 20% and 40% of the pre-tax operating profit of Shenzhen Xunlei according to the terms and provisions of these agreements, respectively (in aggregate 80% of pre-tax operating profit of Shenzhen Xunlei). In addition, these agreements also allow both parties to review and adjust the above mentioned percentage every six months according to the business operation and income of Shenzhen Xunlei so as to enable Giganology Shenzhen to extract substantially all the after tax operating profit of Shenzhen Xunlei. The amount of service fees payable from Shenzhen Xunlei to Giganology Shenzhen for the years ended December 31, 2016, 2017 and 2018 was USD 1,088,000, USD 1,155,000 and USD 825,000, respectively. For the Exclusive Technology Support and Services Agreement and the Exclusive Technology Consulting and Training Agreement, the term of these agreements will expire in 2025 and may be extended with Giganology Shenzhen’s written confirmation prior to the expiration date. Giganology Shenzhen is entitled to terminate the agreement at any time by providing 30 days’ prior written notice to Shenzhen Xunlei. For the Proprietary Technology License Contract, the term of this contract will expire in 2022 and may be extended with Giganology Shenzhen’s written confirmation prior to the expiration date. Giganology Shenzhen grants Shenzhen Xunlei a non-exclusive and non-transferable right to use Giganology Shenzhen’s proprietary technology. Shenzhen Xunlei can only use the proprietary technology to conduct business according to its authorized business scope. Giganology Shenzhen or its designated representative(s) owns the rights to any new technology developed due to implementation of this contract. —Intellectual Properties Purchase Option Agreement between Giganology Shenzhen and Shenzhen Xunlei. Giganology Shenzhen has an option to acquire Shenzhen Xunlei’s intellectual properties at the lowest price permissible by the then-applicable PRC laws and regulation. The term of this contract will expire in 2022 and may be automatically extended for an additional 10 years at Giganology Shenzhen’s discretion. — Call Option Agreement —Giganology Shenzhen has an option to acquire all of the outstanding shares of Shenzhen Xunlei at a purchase price equal to RMB 1 or the lowest price permissible by the then-applicable PRC laws and regulation. The term of the agreement will expire in 2022 and may be extended at Giganology Shenzhen’s discretion. As a result of these agreements (collectively defined as “Structured Service Contracts”), Giganology Shenzhen can exercise effective control over Shenzhen Xunlei, receives all of the economic benefits and residual interest and absorbs all of the risks and expected losses from Shenzhen Xunlei as if it were the sole shareholder, and has an exclusive option to purchase all of the equity interest in Shenzhen Xunlei at a minimal price. Therefore, Giganology Shenzhen is considered the primary beneficiary of Shenzhen Xunlei and accordingly Shenzhen Xunlei’s results of operations, assets and liabilities have been consolidated in the Company’s financial statements. VIE-Related Risks It is possible that the Group’s operation of certain of its operations and businesses through VIEs could be found by PRC authorities to be in violation of PRC laws and regulations prohibiting or restricting foreign ownership of companies that engage in such operations and businesses. While the Group’s management considers the possibility of such a finding by PRC regulatory authorities under current laws and regulations to be remote, on January 19, 2015, the Ministry of Commerce of the PRC, or (the “MOFCOM”) released on its Website for public comment a proposed PRC law (the “Draft FIE Law”) that appears to include VIEs within the scope of entities that could be considered to be foreign invested enterprises (or “FIEs”) that would be subject to restrictions under existing PRC law on foreign investment in certain categories of industry. Specifically, the Draft FIE Law introduces the concept of “actual control” for determining whether an entity is considered to be an FIE. In addition to control through direct or indirect ownership or equity, the Draft FIE Law includes control through contractual arrangements within the definition of “actual control.” If the Draft FIE Law is passed by the People’s Congress of the PRC and goes into effect in its current form, these provisions regarding control through contractual arrangements could be construed to reach the Group’s VIE arrangements, and as a result the Group’s VIEs could become explicitly subject to the current restrictions on foreign investment in certain categories of industry. The Draft FIE Law includes provisions that would exempt from the definition of foreign invested enterprises entities where the ultimate controlling shareholders are either entities organized under PRC law or individuals who are PRC citizens. On December 26, 2018, the Standing Committee of National People’s Congress published the Draft FIE Law on its official website for public consultation The 2018 Draft Foreign Investment Law does not explicitly recognize the variable interest entity structure as a form of foreign investment. Since the 2018 Draft Foreign Investment Law remains silent with respect to the variable interest entity structure as a form of foreign investment, the validity of the Group’s VIE structure as a whole and each of the agreements comprising VIEs will not be affected by the 2018 Draft Foreign Investment Law. It leaves leeway for government’s future regulation of the variable interest entity structure. However, the 2018 Draft Foreign Investment Law was planned to be submitted to the 2nd Session of the 13th National People’s Congress for deliberation and voting. Substantial uncertainties exist with respect to its enactment timetable, interpretation and implementation, and whether it will be enacted in the current form. In addition to three major forms of foreign investment, foreign investment also includes any other form of foreign investments set forth in laws, administrative regulations, or provisions of the State Council. It is possible that future laws, administrative regulations, or provisions of the State Council may recognize the variable interest entity structure as a form of foreign investment but at the same time impose additional requirements/restrictions on the contractual arrangements. It is also possible that further laws, administrative regulations, or provisions of the State Council may explicitly exclude the variable interest entity structure as a form of foreign investment. If a finding were made by PRC authorities, under existing laws and regulations or under the Draft FIE Law if it becomes effective, that the Group’s operation of certain of its operations and businesses through VIEs, regulatory authorities with jurisdiction over the licensing and operation of such operations and businesses would have broad discretion in dealing with such a violation, including levying fines, confiscating the Group’s income, revoking the business or operating licenses of the affected businesses, requiring the Group to restructure its ownership structure or operations, or requiring the Group to discontinue all or any portion of its operations. Any of these actions could cause significant disruption to the Group’s business operations, and have a severe adverse impact on the Group’s cash flows, financial position and operating performance. In addition, it is possible that the contracts among the Group, the Group’s VIEs and shareholders of its VIEs would not be enforceable in China if PRC government authorities or courts were to find that such contracts contravene PRC law and regulations or are otherwise not enforceable for public policy reasons. In the event that the Group was unable to enforce these contractual arrangements, the Group would not be able to exert effective control over the affected VIEs. Consequently, such VIE’s results of operations, assets and liabilities would not be included in the Group’s consolidated financial statements. If such were the case, the Group’s cash flows, financial position and operating performance would be severely adversely affected. The Group’s contractual arrangements with respect to its consolidated VIEs are approved and in place. The Group’s management believes that such contracts are enforceable, and considers the possibility remote that PRC regulatory authorities with jurisdiction over the Group’s operations and contractual relationships would find the contracts to be unenforceable. |

| Summary of significant accounting policies |
The consolidated financial statements of the Group have been prepared in accordance with accounting principles generally accepted in the United States of America (‘‘U.S. GAAP’’). Significant accounting policies followed by the Group in the preparation of the accompanying consolidated financial statements are summarized below. The Restructuring was accounted for at historical costs. The assets and liabilities of Shenzhen Xunlei are consolidated in the Company’s financial statements at carryover basis. The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the accompanying consolidated financial statements and related disclosures. Actual results could differ materially from these estimates. Significant accounting estimates reflected in the Group’s consolidated financial statements mainly include allowance for doubtful accounts, valuation allowance of deferred tax assets, sales rebate to advertising agencies, amortization period of online game revenue, amortization of content copyrights, fair value of content copyrights exchange, impairment assessment of goodwill and impairment assessment of long-lived assets. In addition, the Group uses assumptions in a valuation model to estimate the fair value of share options granted, warrants issued and underlying common shares. Management bases the estimates on historical experience and on various other assumptions that are believed to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities. Actual results could differ from these estimates.
The consolidated financial statements include the financial statements of the Company, its subsidiaries, VIE for which the Company is the primary beneficiary and its subsidiaries. All significant transactions and balances among the Company, its subsidiaries, VIE and its subsidiaries have been eliminated upon consolidation. A subsidiary is an entity in which the Company, directly or indirectly, controls more than one-half of the voting power, or has the power to appoint or remove the majority of the members of the board of directors to cast majority of votes at meetings of the board of directors or to govern the financial and operating policies of the investee under a statute or agreement among the shareholders or equity holders. An entity is considered to be a VIE if the entity’s equity holders do not have the characteristics of a controlling financial interest or do not have sufficient equity at risk for the entity to finance its activities without additional subordinated financial support from other parties. The Group consolidates entities for which the Company is the primary beneficiary if the entity’s other equity holders do not have the characteristics of a controlling financial interest or do not have sufficient equity at risk for the entity to finance its activities without additional subordinated financial support from other parties. In determining whether the Company or its subsidiary is the primary beneficiary of a VIE, the Company considered whether it has the power to direct activities that are significant to the VIE’s economic performance, including the power to appoint senior management, right to direct company strategy, power to approve capital expenditure budgets, and power to establish and manage ordinary business operation procedures and internal regulations and systems. Management has evaluated the contractual arrangements among Giganology Shenzhen, Shenzhen Xunlei and its shareholders and concluded that Giganology Shenzhen receives all of the economic benefits and absorbs all of the expected losses from Shenzhen Xunlei and has the power to direct the aforementioned activities that are significant to Shenzhen Xunlei’s economic performance, and is the primary beneficiary of Shenzhen Xunlei. Therefore, Shenzhen Xunlei and its subsidiaries’ results of operation, assets and liabilities have been included in the Group’s consolidated financial statements. Management monitors the regulatory risk associated with these contractual arrangements. See Note 26 for further discussion. Non-controlling interests represent the portion of the net assets of a subsidiary attributable to interests that are not owned by the Company. The non-controlling interests are presented in the consolidated balance sheets, separately from equity attributable to the shareholders of the Company. Non-controlling interests in the results of the Group is presented on the face of the consolidated statements of comprehensive income as an allocation of the total income or loss for the year between non-controlling shareholders and the shareholders of the Company.
When disposals that represent a strategic shift that has (or will have) a major effect on the entity’s results and operations would qualify as discontinued operations. Discontinued operations are reported when a component of an entity comprising operations and cash flows that can be clearly distinguished, operationally and for financial reporting purposes, from the rest of the entity is classified as held for disposal or has been disposed of, if the component either (1) represents a strategic shift or (2) have a major impact on an entity’s financial results and operations. Examples include a disposal of a major geographical location, line of business, or other significant part of the entity, or disposal of a major equity method investment. In the consolidated statement of comprehensive income, result from discontinued operations is reported separately from the income and expenses from continuing operations and prior periods are presented on a comparative basis. Cash flows for discontinuing operations are presented separately in note 3. In order to present the financial effects of the continuing operations and discontinued operations, revenues and expenses arising from intra-group transactions are eliminated except for those revenues and expenses that are considered to continue after the disposal of the discontinued operations. Non-current assets or disposal groups are classified as held for sale assets when the carrying amount is to be recovered principally through a sale transaction rather than through continuing use. For this to be the case, the asset or disposal group must be available for immediate sale in its present condition subject only to terms that are usual and customary for sale of such assets or disposal groups and the sale must be highly probable. Non-current assets classified as held for sale and disposal groups are measured at the lower of their carrying or fair value less costs to sell.
The Company’s reporting and functional currency is the United States Dollar (‘‘USD’’). Xunlei BVI and Xunlei HK’s functional currency is the USD. The functional currency of other subsidiaries, VIE and its subsidiaries located in the PRC is the Renminbi (‘‘RMB’’), which is their respective local currency. Transactions denominated in foreign currencies are remeasured into the functional currency at the exchange rates prevailing on the transaction dates. Financial assets and liabilities denominated in foreign currencies are remeasured into the functional currency using the applicable exchange rates prevailing at the balance sheet date. The resulting exchange gains and losses from foreign currency transactions are included in other income (loss) within the consolidated statements of comprehensive income. The Company uses the monthly average exchange rate for the year and the exchange rates at the balance sheet date to translate the operating results and financial position, respectively, of its subsidiaries whose functional currency is other than the USD. The resulting translation differences are recorded in cumulated translation adjustments, a component of shareholders’ equity. The exchange rate used is released by Chinese State Administration of Foreign Exchange.
Cash and cash equivalents include cash on hand, cash in bank and time deposits placed with banks or other financial institutions, which have original maturities of three months or less and are readily convertible to known amounts of cash.
Short-term investments include deposits placed with banks with original maturities of more than three months but less than one year and investments in financial instruments with a variable interest rate indexed to the performance of underlying assets. In accordance with ASC 825 Financial Instruments , for investments in financial instruments with a variable interest rate indexed to performance of underlying assets, the Group 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. Interest generated from short term investments are recorded when interest payments are received at the maturity date. It is recorded as “other income” on the statement of comprehensive income and measured based on the actual amount of interest the Group received.
The Group’s financial instruments consist principally of cash and cash equivalents, short-term investments, accounts receivable, other receivables, amounts due from/(to) related parties, accounts payable, and other payables. The carrying value of these balances, with the exception of short-term investments (see note 2 (f)), approximates their fair value due to the current and short term nature of these balances.
Accounts receivable are presented net of allowance for doubtful accounts. The Group evaluates the creditworthiness of each customer at the time when services are rendered and continuously monitor the recoverability of the accounts receivable. The Group uses specific identification method in providing for bad debts when facts and circumstances indicate that collection is doubtful and a loss is probable and estimable. If the financial conditions of its customers were to deteriorate, resulting in an impairment of their ability to make payments, additional allowances might be required. The allowance for doubtful accounts is based on the best facts available and is re-evaluated and adjusted on a regular basis as additional information is received. Some of the factors that the Group considers in determining whether a bad debt allowance is recorded on an individual customer are: 1) the customer's past payment history and whether it fails to comply with its payment schedule; 2) whether the customer is in financial difficulty due to economic or legal factors; 3) a significant dispute with the customer has occurred; 4) the objective evidence which indicates non-collectability of the accounts receivable. The allowances provided for Accounts Receivable from continuing operations as of December 31, 2017 and 2018 were USD 31,000 and USD 7,709,000, respectively. If the Group determines that an allowance is needed for a customer, the Group will discontinue business with it unless they start to resume payment. The accounts receivable is written-off when the Group ceases to pursue collection. Any changes in the estimates may cause the Group's operating results to fluctuate.
Inventories are stated at the lower of cost or net realizable value. Cost is determined using actual cost on a weighted average basis. Net realizable value is the amount that can be realized from the sale of the inventory in the normal course of business after allowing for the costs of realization.
The Group holds investments in privately held companies. Prior to adopting ASU 2016-01, Financial Instruments on January 1, 2018, for those investments over which the Group does not have significant influence and without readily determined fair value, the Group carried the investment at cost and only adjusted for other-than-temporary declined in fair value and distribution of earnings that exceed the Group’s share of earnings. On January 1, 2018, the Group adopted ASU 2016-01, Financial Instruments , and started to measure long-term equity investments, other than equity method investments, at fair value through earnings. For those investments over which the Group does not have significant influence and without readily determinable fair value, the Group elected to record these investments at cost, less impairment, and plus or minus subsequent adjustments for observable price changes. Under this measurement alternative, changes in the carrying value of equity investments will be required to be made whenever there are observable price changes in orderly transactions for the identical or similar investment of the same issuer. Management regularly evaluates the impairment of long-term equity investments based on performance and financial position of the investee as well as other evidence of market value. Such evaluation includes, but it 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 recognised equal to the excess of the investment costs over its fair value at the end of each reporting period for which the assessment is made. The fair value would then become the new cost basis of investment. During the years ended December 31, 2016, 2017 and 2018 the Group recognized an impairment of USD 1.66 million, USD 0.6 million and USD 7.8 million, respectively. During the years ended December 31, 2016, 2017 and 2018, the Group recognized share of loss of equity investees of USD nil, USD 1.3 million and USD 0.3 million from Shenzhen Mojinggou Information Services Co., Ltd. (previously known as Xunlei Big Data Information Service Co., Ltd.) (“Big Data”) and Zhuhai Qianyou Technology, Co., Ltd. (“Zhuhai Qianyou”) respectively.
Property and equipment are stated at historical cost less accumulated depreciation and impairment loss, if any. Depreciation is calculated using the straight-line method over their estimated useful lives. Residual rate is determined based on the economic value of the asset at the end of the estimated useful life as a percentage of the original cost. If the Group commits to a plan to abandon a long-lived asset before the end of its previous estimated useful life, depreciation shall be revised to reflect a shortened useful life.
Repair and maintenance costs are expensed as incurred. Expenditures that substantially increase an asset’s useful life are capitalized. Upon sale or disposal, gain or loss on the 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 loss. The cost and related accumulated depreciation are removed from the balance sheets.
Goodwill represents the excess of the purchase consideration over the fair value of the identifiable tangible and intangible assets acquired and liabilities assumed from the acquired entity as a result of the Company’s acquisitions of interests in its subsidiaries and consolidated VIEs. Goodwill is not amortized but is tested for impairment on an annual basis, or more frequently if events or changes in circumstances indicate that it might be impaired. The Company first assesses qualitative factors to determine whether it is necessary to perform the two-step quantitative goodwill impairment test. In the qualitative assessment, the Company considers primary factors such as industry and market considerations, overall financial performance of the reporting unit, and other specific information related to the operations. Based on the qualitative assessment, if it is more likely than not that the fair value of each reporting unit is less than the carrying amount, the quantitative impairment test is performed. In performing the two-step quantitative impairment test, the first step compares the fair values of each reporting unit to its carrying amount, including goodwill. 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 the purposes of evaluating goodwill impairment and does not result in an entry to adjust the value of any assets or liabilities. Application of a goodwill impairment test requires significant management judgment, including the identification of reporting units, allocation of assets, liabilities and goodwill to reporting units, and determination of the fair value of each reporting unit. No goodwill impairment losses were recognized for the years ended December 31, 2016, 2017 and 2018 based on the impairment test performed by the Group.
Intangible assets, which include computer software, internal use software development costs, online game licenses, domain names, land use rights, trademarks, technology (including right-to-use), non-compete agreement and audio-visual license, are carried at cost less accumulated amortization and impairment loss, if any. Exclusive game licenses are amortized using the straight-line method over their licensing period of three years. Computer software, internal use software and domain name are amortized using the straight-line method over their estimated useful life of five years. Land use right is amortized using the straight-line method over their estimated useful life of thirty years. Audio-visual license acquired is amortized using the straight-line method over its estimated useful life of nine years.
For other long-lived assets, the Group evaluates its long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may no longer be recoverable. The Group assesses the recoverability of the long-lived assets by comparing the carrying value of the long-lived assets to the estimated undiscounted future cash flows expected to be received from use of the assets and their eventual disposition at the lowest level of identifiable cash flows. Such assets are considered to be impaired if the sum of the expected undiscounted cash flows is less than the carrying amount of the assets. If the Group identifies an impairment, the carrying value of the asset will be reduced to its estimated fair value based on a discounted cash flow approach or, when available and appropriate, to comparable market values.
In the normal course of business, the Group is subject to contingencies, such as legal proceedings and claims arising out of its business, that cover a wide range of matters. Liabilities for such contingencies are recorded when it is probable that a liability has been incurred and the amount of the assessment can be reasonably estimated. In regards to legal cost, the Group recorded such costs as incurred. Certain conditions may exist as of the date the financial statements are issued, which may result in a loss to the Group, but which will only be resolved when one or more future events occur or fail to occur. The Group’s management and its legal counsel assess such contingent liabilities, and such assessment inherently involves an exercise of judgment. In assessing loss contingencies related to legal proceedings that are pending against the Group or unasserted claims that may result in such proceedings, the Group, in consultation with its legal counsel, evaluates the perceived merits of any legal proceedings or unasserted claims as well as the perceived merits of the amount of relief sought or expected to be sought therein. If the assessment of a contingency indicates that it is probable that a material loss has been incurred and the amount of the liability can be estimated, then the estimated liability would be accrued in the Group’s financial statements. If the assessment indicates that a potentially material loss contingency is not probable, but is reasonably possible, or is probable but cannot be estimated, then the nature of the contingent liability, together with an estimate of the range of possible loss, if determinable and material, would be disclosed.
Leases in which a significant portion of the risks and rewards of ownership are retained by the lessor are classified as operating leases. Payments made under operating lease are charged to the statements of comprehensive income on a straight-line basis over the period of the lease.
The Group adopted ASC Topic 606 Revenue from Contracts with Customer (“ASC 606”), from January 1, 2018, using the modified retrospective method. Revenues for the year ended December 31, 2018 were presented under ASC 606, and revenues for the years ended December 31, 2017 and 2016 were not adjusted and continue to be presented under ASC Topic 605, Revenue Recognition. The core principle of the ASC 606 is an entity should recognize revenues 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. Adoption had no significant impact on the consolidated financial statements. Significant accounting policy and relevant disclosure have been updated hereinafter. Effective January 1, 2018, the Group evaluates and recognizes revenue based on the criteria set forth in ASC 606 by: Step 1: Identify the contract(s) with a customer Step 2: Identify the performance obligations in the contract Step 3: Determine the transaction price Step 4: Allocate the transaction price to the performance obligations in the contract Step 5: Recognize revenues when (or as) the entity satisfies a performance obligation Revenue is recognized when or as the control of the services or goods is transferred to the customer. Depending on the terms of the contract and the laws that apply to the contract, control of the services and goods may be transferred over time or at a point in time. A contract liability is the Group’s obligation to transfer goods or services to a customer for which the Group has received consideration (or an amount of consideration is due) from the customer. Contract costs includes incremental costs of obtaining a contract and costs to fulfil a contract. The Group generates revenues from various streams. Net revenues presented in the consolidated statements of loss represent revenues from service and product sales net off sales discount, value-added tax and related surcharges. The Group operates a prepaid virtual items system, under which, prepaid virtual items at fixed face value are sold to third parties. Virtual items purchased can be used to subscribe for membership or purchase of virtual items in online games and live streaming, as discussed below. Virtual items sold but not yet consumed by the users are recorded as “Receipts in advance from customers” and upon consumption, they are recognized as membership subscription, online game revenue and live streaming revenue according to the respective prescribed revenue recognition policies addressed below. The Group’s revenue recognition policies effective on the adoption date of ASC 606 are as follows:
The Group operates a VIP membership program where VIP members can have access to high speed online acceleration services, online streaming and other access privileges. The membership fee is time-based and is collected up-front from subscribers except in the cases when they elect to pay via their mobile operators. The membership fee is collected when the subscribers pay for the monthly phone bills. The terms of time-based subscriptions range from one month to twelve months, with the subscribers having the option to renew the contract. The receipt of subscription fee is initially recorded as contract liabilities. The Group satisfies its various performance obligations by providing services throughout the subscription period and revenue is recognized rateably over the period of subscription as services are rendered. Unrecognized portion beyond 12 months from balance sheet date is classified as a long-term liability. The Group evaluated the principal versus agent criteria and determined that the Group is the principal in the transaction and accordingly record revenue on a gross basis. In determining whether to report revenues gross for the amount of subscription revenue, the Group assesses whether it maintains the principal relationship with the VIP members, whether it bears the credit risk and whether it establishes prices for the end users. Service fees levied by online system, fixed phone line and mobile payment channels (‘‘Payment handling charges’’) are recorded as the cost of revenues in the same period as the revenue for the membership fee is recognized.
Advertising revenues are derived principally from arrangements where the a dvertisers pay to place their advertisements on the Group’s platform over a particular period of time. It includes multiple performance obligations, primarily for advertisements to be displayed in different spots at different times, placed under different formats including but are not limited to videos, banners, links, logos and buttons. Advertisements on the Group’s platform are generally charged on the basis of duration, and advertising contracts are signed to establish the fixed price and the advertising services to be provided. The Group enters into advertising contracts with third party advertising agencies that represents advertisers, as well as directly with advertisers. A typical contract term would range from a few days to 3 months. Both third party advertising agencies and direct advertisers are generally billed at the end of the display period and payments are due usually within 3 months. Where the Group’s customers purchase multiple advertising spaces with different display periods in the same contract, the Group allocates the total consideration to the various advertising elements based on their relative fair values and recognizes revenue for the different elements over their respective display periods. The Group determines the fair values of different advertising elements based on the prices charged when these elements were sold on a standalone basis. The Group recognizes revenue on the elements delivered and defers the recognition of revenue for the fair value of the undelivered elements until the remaining obligations have been satisfied. Where all of the elements within an arrangement are delivered uniformly over the agreement period, the revenue is recognized on a straight line basis over the contract period. Transactions with third party advertising agencies For contracts entered into with third party advertising agencies, the third party advertising agencies will in turn sell the advertising services to advertisers. Revenue is recognized ratably over the contract period of display. The Group provides sales incentives in the forms of discounts and rebates to third party advertising agencies based on purchase volume. As the advertising agencies are viewed as the customers in these transactions, revenue is recognized based on the price charged to the agencies, net of sales incentives provided to the agencies. Sales incentives are estimated and recorded at the time of revenue recognition based on the contracted rebate rates and estimated sales volume based on historical experience. Transactions with third party advertising platforms Xunlei began to cooperate with third party advertising platforms such as Guangdiantong and Baidu since the fourth quarter in 2015. In this business model, advertisers put their content on third party advertising platforms and platforms will dispatch the advertising content to Xunlei’s platforms by certain analysis systematically. As the third party advertising platforms are viewed as the customers in these transactions, revenue is recognized monthly based on the data publicized on third party platforms and the price charged to these advertising platforms. Transactions with advertisers The Group also enters into advertisement contracts directly with advertisers. Under these contracts, similar to transactions with third party advertising agencies, the Group recognizes revenue ratably over the contract period of display. The terms and conditions, including price, are fixed according to the contract between the Group and the advertisers. The Group also performs credit assessment of all advertisers prior to entering into contracts. Revenue is recognized based on the amount charged to the advertisers, net of discounts. The Group has estimated and recorded sales rebates provided to the agencies and advertisers of USD 15,000, USD 440,000 and USD 394,000 for the years ended December 31, 2016, 2017 and 2018, respectively.
The Group operates live streaming platform and users can purchase virtual gifts which they can then send to performers in the live streaming platform. The consumption of each virtual gift sold to users is considered as the performance obligation. The Group does not have further obligations to the user after the virtual gifts are consumed immediately or after the stated period for time-based items. The revenue from consumable item is recognized at fair value of the virtual items, as Xunlei is the principal in this arrangement, based on actual consumption of virtual items by the paying users. The revenue from time-based item is recognized over the duration of stated period of the item.
Online games comprise web games, mobile games and PC games. Users play games through the Group’s platform free of charge and are charged for purchases of virtual items including consumable and perpetual items, which can be utilized in the online games to enhance their game-playing experience. The utilization of the virtual item is considered performance obligation by the Group and revenue is allocated to each performance obligation on a relative stand-alone selling price basis, which are determined based on the prices charged to customers. Consumable items represent virtual items that can be consumed by a specific user within a specified period of time. Perpetual items represent virtual items that are accessible to the users’ account over the life of the online game. Pursuant to contracts signed between the Group and game developers, revenue from the sale of virtual items are shared based on a pre-agreed ratio for each game. The Group enters into both non-exclusive and exclusive licensing contracts with game developers. Non-exclusive game licensed contracts The games under non-exclusive licensed contracts are maintained, hosted and updated by the game developers. The Group mainly provides access to the platform and limited after-sale services to the game players. The determination of whether to record these revenues using the gross or net method is based on an assessment of various factors; the primary factors are whether the Group acts as the principal in offering services to the game players or as agent in the transaction, and the specific requirements of each contract. The Group determined that for non-exclusive game licensed arrangements, the third party game developers are the principal given that the game developers design and develop the game services offered, have reasonable latitude to establish prices of game virtual items, and are responsible for maintaining and upgrading the game content and virtual items. Accordingly, the Group records online game revenue, net of the portion remitted to the game developers. Given that online games are managed and administered by the game developers for non-exclusive licensed games, the Group does not have access to the data on the consumption details and the types of virtual items purchased by the game players. The Group has adopted a policy to recognize revenues relating to both consumable and perpetual items over the shorter of 1) estimated lives of the games and 2) the estimated lives of the user relationship with the Group, which were approximately one to ten months for the periods presented. Adjustments arising from the changes of estimated lives of virtual items are applied prospectively as such changes are resulted from new information indicating a change in the game player behavioral patterns. Exclusive licensing game contracts For exclusive licensing contracts with game developers, the games are maintained and hosted by the Group. Accordingly, the Group is determined to be the principal, the Group records online game revenue on a gross basis, with the amount remitted to the game developers reported as cost of revenue. Payment handling charges are recognized as cost of revenues when the related revenues are recognized. For exclusive licensed games which are maintained on the Group’s server, the Group has access to the data on the consumption details and types of virtual items purchased by the game players. The Group does not maintain information on consumption details of virtual items, and only have limited information related to the frequency of log-ons. Given that a substantial portion of the virtual items purchased by the game players in exclusive licensed games are perpetual items, management determined that it would be most appropriate to recognize revenue over the shorter of 1) estimated lives of the games and 2) the estimated lives of the user relationship with the Group, which were approximately one to six months for the periods presented. Revenues related to consumable items are recognized immediately upon consumption. Game players can purchase prepaid virtual items which can be used to purchase virtual items via online channels. The Group incurs service fees levied by those payment channels, and such payment expenses are recorded as the cost of revenues when the related revenues are recognized. For both non-exclusive and exclusive licensed games, the Group estimates the life of virtual items to be the shorter of the estimated lives of the games and the estimated lives of the user relationship. The estimated user relationship period is based on data collected from those users who have purchased virtual items. To estimate the life of the user relationship, the Group maintains a software system that captures the following information for each user: the date of first log-on, the date the user ceases to play the game and frequency of log-ons. The Group estimates the life of the user relationship to be the weighted average period from the first purchase of a virtual item to the date the user ceases to play the game based on the frequency of log-ons. To estimate the life of the games, the Group considers both games that they operate as well as games in the market that are of a similar nature. The Group categorizes these games by their nature, such as simulation games, role playing games and others, which appeal to players belonging to different demographics. The Group estimates that the life of each group of the games to be the average period from the date of launch for such games to the date the games are expected to be removed from the website or terminated altogether. When the Group launches a new game, they estimate the life of the game and user relationship based on lives of other similar games in the market until the new game establishes its own history. The Group also considers the game’s profile, attributes, target audience, and its appeal to players of different demographic groups in estimating the user relationship period. The consideration of user relationship with each online game is based on the Group’s best estimate that takes into account all known and relevant information at the time of assessment. Adjustments arising from the changes of estimated lives of virtual items are applied prospectively as such changes are resulted from new information indicating a change in the game player behavioral patterns. Any changes in the estimates of lives of virtual items may result in the Group’s revenues being recognized on a basis different from prior periods and may cause the Group’s operating result to fluctuate. The Group periodically assesses the estimated lives of the virtual items and any changes from prior estimates are accounted for prospectively. Any adjustments arising from changes in user relationship as a result of new information will be accounted as a change in accounting estimate in accordance with ASC 250 Accounting Changes and Error Corrections . The Group entered into a legally binding agreement to sell its web game business in December 2017. Web game revenue recognized from discontinued operations was USD 15,981,000, USD 11,428,000 and USD 656,000 for the years ended December 31, 2016, 2017 and 2018, respectively.
The Group enters into contracts with certain third party portals/websites in which the Group is obliged to redirect online traffic to these third party portals/websites. On a monthly basis, the Group receives data on the user traffic and the related monthly revenue from these third party portals/ websites. Under these programs, the Group recognizes its share of revenues based on contractual rates applied to user traffic redirected to the advertisements of the third parties.
As part of the Group’s cloud computing business, the Group engages in sale of OneThing Cloud. OneThing Cloud is a personal cloud hardware device. OneThing Cloud allows users to share their idle bandwidth with the Group, in exchange for LinkTokens. LinkTokens are not convertible into cash but can be redeemed for products and services offered in the LinkToken Mall and exchange for a limited number of other products and services under the terms determined by the corresponding operators. LinkTokens represent an obligation to deliver future services by the operators of LinkToken Mall and other platforms. The bandwidth shared by the users in exchange for LinkTokens is an identifiable benefit, of which the Group can reasonably estimate fair value. The benefit that the Group receives from user’s contribution of bandwidth is independent from OneThing Cloud that the Group sells to users. The sales of OneThing Cloud and receipt of excess bandwidth by the Group are considered separate transactions. Therefore, sales of OneThing Cloud are reported as revenue, while LinkTokens given in exchange for bandwidth are reported as bandwidth cost. The Group sells OneThing Cloud primarily through online e-commerce platforms, the performance obligation is satisfied when the item is dispatched to the end customers. The LinkTokens issued represent an obligation to deliver future services. Therefore, contract liabilities were recognized for all LinkTokens issued. Revenue will be recognized upon redemption of the LinkTokens, the fair value of which is measured by bandwidth costs divided by total number of LinkTokens issued. Breakage is taken into account based on historical experience. The core business principle of cloud computing is to collect idle uplink capacity from individuals with compensation, and sells to online video streaming platforms. On a monthly basis, the Group records the bandwidth it delivers and recognizes revenue from these online video streamers under contractual rates applied (price per GB of bandwidth multiplies total GBs of bandwidth per month). The cost of collecting idle bandwidth is recorded as bandwidth costs within cost of revenues upon the Group receives the idle bandwidth. Revenue is recognized net of return allowances when the products are delivered and title passes to customers. Return allowances, which reduce net revenues, are estimated based on historical experiences. Product warranties are estimated and recognized at the time the Company recognizes revenue. The warranty period is 1 year. The Company accrues warranty liabilities at the time of sale, based on historical and projected incident rates and expected future warranty costs.
Sales and marketing expenses comprise primarily of salary, benefits of sales and marketing personnel and external advertising and market promotion expenses. The external advertising and market promotion expenses from continuing operations amounted to approximately USD 6,666,000, USD 10,345,000 and USD 22,935,000 for the years ended December 31, 2016, 2017 and 2018, respectively. Shipping and handling fee is recorded in sales and marketing expenses.
General and administrative expenses consist primarily of salary and benefits, professional service fees, legal expenses and other administrative expenses.
The Group incurred research and development costs to develop its downloading software. Costs incurred during the research phase are expensed as incurred. Costs incurred for the development of the downloading software prior to the establishment of technological feasibility, which is when a working model is available, are expensed when incurred. The development costs qualified for capitalization have been immaterial for the periods presented. The Group also incurred development costs in connection with an internal-use ERP software to further enhance management to monitor the business. While internal and external costs incurred during the preliminary project stage are expensed as incurred, costs relating to activities during the application development stages have been capitalized. During each of the three years ended December 31, 2018, no software development costs were capitalized as intangible assets. In addition, the Group incurred other research and development costs in relation to software used to support its operations. Any development costs qualified for capitalization were immaterial for the periods presented.
Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statements’ carrying amounts of existing assets and liabilities and their respective tax bases and tax loss carry forwards. Deferred tax assets and liabilities are measured using enacted tax rates in effect for the year in which the difference is expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in the consolidated statement of operations in the period that includes the enactment date. A valuation allowance is provided to reduce the carrying amount of deferred tax assets if it is considered more likely than not that some portion, or all, of the deferred tax assets will not be realized. The estimation of future taxable income involves significant judgement and estimates. Based on management's estimated future taxable income, management concluded that it is more likely than not that the net operating losses carried forward can be utilized prior to their respective expiration dates. The Group adopted the guidance regarding uncertain tax positions and evaluated its open tax positions that exist in each jurisdiction for each reporting period. If an uncertain tax position is taken or expected to be taken in a tax return, the tax benefit from that uncertain position is recognized in the Group’s consolidated financial statements if it is more likely than not that the position is sustainable upon examination by the relevant taxing authority. The Group did not have any significant uncertain tax position and there was no effect on its financial condition or results of operations as a result of implementing the new guidance. The Group recognizes interest and penalties accrued on any unrecognized tax benefits as a component of income tax expense, if any. No significant interest and penalties were recorded in the years ended December 31, 2016, 2017 and 2018. Transition from PRC Business Tax to PRC Value Added Tax VAT payable on goods sold or taxable labor services provided by a general VAT taxpayer for a taxable period is the net balance of the output VAT for the period after crediting the input VAT for the period. In addition to the product revenues currently subject to VAT at a rate of 16 % (17 % before May 1, 2018), the Group’s advertising revenues, subscription revenue, online game revenue, revenue from cloud computing and live streaming revenue are now subject to VAT at a rate of 6%.
Full-time employees of the Company’s subsidiaries, consolidated VIE and its subsidiaries in the PRC participate in a government mandated multi-employer defined contribution plan pursuant to which certain pension benefits, medical care, unemployment insurance, employee housing fund and other welfare benefits are provided to employees. Chinese labor regulations require that the subsidiaries and VIEs of the Company make contributions to the government for these benefits based on certain percentages of the employees’ salaries. The Group has no legal obligation for the benefits beyond the contributions made. The total amounts from continuing operations for such employee benefits, which are expensed as incurred, were USD 8,645,000, USD 10,123,000 and USD 12,501,000 for the years ended December 31, 2016, 2017 and 2018, respectively.
The Group measures share-based compensation at the grant date based on the fair value of the award determined using the Black-Scholes option pricing model. As the Group has granted share options and restricted shares with service-only condition, the Group elected to recognize compensation costs net of estimated forfeitures on a straight line basis over the requisite service period, which is generally the same as the vesting period. The amount of compensation cost recognized at any date is at least equal to the portion of the grant-date value of the award that is vested at that date.
The Group receives subsidies from the local PRC government for general use or purchase of equipment. General-use subsidies which are not subject to any conditions or specific use requirements are recorded as subsidy income in the consolidated statements of operations. Subsidies for purchase of equipment are recorded as deferred government grant when received, and are recorded as other income over the expected useful life of the assets after the related equipment has been purchased.
The Group’s Chief Executive Officer has been identified as the chief operating decision maker (“CODM”), who reviews consolidated operating results of the Group when making decisions about allocating resources and assessing performance of the Group as a whole. The Group has internal reporting of revenue, cost and expenses that does not distinguish between segments, and reports costs and expense by nature as a whole. The Group does not distinguish between markets or segments for the purpose of internal reporting. Management has determined that the Group operates and manages its business as a single segment which is the operation of its online media platform, over 99% of revenues of the Group were derived from mainland China. An analysis of the different types of revenues for the years ended December 31, 2016, 2017 and 2018 are summarized as follows:
Net basic loss per share is computed by dividing net loss attributable to holders of common shares by the weighted-average number of common shares outstanding during the year using the two class method. Using the two class method, net loss is allocated between common shares and other participating securities based on their participating rights. Net diluted loss per share is calculated by dividing net loss attributable to common shareholders as adjusted for the effect of dilutive common equivalent shares, if any, by the weighted-average number of common and dilutive common equivalents shares outstanding during the year. Dilutive equivalent shares are excluded from the computation of diluted loss per share if their effects would be anti-dilutive. Common share equivalents consist of the common shares issuable upon the conversion of the stock options, using the treasury stock method.
Comprehensive income is defined as the change in equity of a Group during the period from transactions and other events and circumstances excluding transactions resulting from investments from shareholders and distributions to shareholders. Accumulated other comprehensive income, as presented on the accompanying consolidated balance sheets, consists of cumulative translation adjustment.
The Group’s subsidiaries, consolidated VIE and its subsidiaries incorporated in the PRC are required on an annual basis to make appropriations of retained earnings set at certain percentage of after-tax profit determined in accordance with PRC accounting standards and regulations (“PRC GAAP”). Appropriation to the statutory general reserve should be at least 10% of the after-tax net income determined in accordance with the legal requirements in the PRC until the reserve is equal to 50% of the entities’ registered capital. The Group is not required to make appropriation to other reserve funds and the Group does not have any intentions to make appropriations to any other reserve funds. The general reserve fund can only be used for specific purposes, such as setting off the accumulated losses, enterprise expansion or increasing the registered capital. Appropriations to the general reserve funds are classified in the consolidated balance sheets as statutory reserves. There are no legal requirements in the PRC to fund these reserves by transfer of cash to restricted accounts, and the Group does not do so. The following table presents the balances of registered capital, additional paid-in-capital and statutory reserves of entities within the Group incorporated in China as of December 31, 2017 and 2018 for the Group’s reporting purpose in China as determined under generally accepted accounting principles in China:
Relevant laws and regulations permit payments of dividends by the PRC subsidiaries and affiliated companies only out of their retained earnings, if any, as determined in accordance with respective accounting standards and regulations. Accordingly, the above balances are not allowed to be transferred to the Company in terms of cash dividends, loans or advances (See also Note 26).
Dividends are recognized when declared. No dividends were declared for the years ended December 31, 2016, 2017 and 2018. The Group does not have any present plan to pay any dividends on common shares in the foreseeable future. The Group currently intends to retain the available funds and any future earnings to operate and expand its business.
Leases. In February 2016, the Financial Accounting Standards Board (“FASB”) issued ASU 2016-02, Leases , which specifies the accounting for leases. For operating leases, ASU 2016-02 requires a lessee to recognize a right-of-use asset and a lease liability, initially measured at the present value of the lease payments, in its balance sheet. The standard also requires a lessee to recognize a single lease cost, calculated so that the cost of the lease is allocated over the lease term, on a generally straight-line basis. In addition, this standard requires both lessees and lessors to disclose certain key information about lease transactions. ASU 2016-02 is effective for publicly traded companies for annual reporting periods, and interim periods within those years, beginning after December 15, 2018. The Group adopted the new standard effective January 1, 2019 on a modified retrospective basis and will not restate comparative periods. The Group estimates approximately USD11.8 million and USD11.4 million would be recognized as total right-of use assets and total lease liabilities, respectively on the consolidated balance sheets as of January 1, 2019. The Group expects that net profit after tax will not be materially changed as a result of adopting the new rules. The adoption of new standard will also result in certain reclassification of operating cash flows and financing cash flows. Financial Instruments-Credit Losses. In June 2016, the FASB issued ASU 2016-13 , Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which requires the measurement and recognition of expected credit losses for financial assets held at amortized cost. ASU 2016-13 replaces the existing incurred loss impairment model with an expected loss methodology, which will result in more timely recognition of credit losses. ASU 2016-13 is effective for annual reporting periods, and interim periods within those years, beginning after December 15, 2019. The Group is currently in the process of evaluating the impact of the adoption of ASU 2016-13 on its consolidated financial statements. Simplifying the Test for Goodwill Impairment . In January 2017, the FASB issued ASU 2017-04 Simplifying the Test for Goodwill Impairment. The guidance removes Step 2 of goodwill impairment tests, which requires a hypothetical purchase price allocation. A goodwill impairment will now be the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. The guidance is to be adopted on a prospective basis for the annual or any interim goodwill impairment tests beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The Group does not expect the adoption to have a material impact on its consolidated financial statements. Compensation—Stock Compensation . In June 2018, the FASB issued ASU 2018-07, Compensation—Stock Compensation (Topic 718): Improvement to Nonemployee Share-based Payment Accounting to amend the accounting for share-based payment awards issued to nonemployees. Under the revised guidance, the accounting for awards issued to nonemployees will be similar to the model for employee awards. The update is effective for public business entities for fiscal years beginning after December 15, 2018, including interim periods within that fiscal year. The Group adopted this new standard effective on January 1, 2019. The adoption of ASU 2018-07 did not have a material impact on the Group’s consolidated financial statements. Fair Value Measurement. In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement , which eliminates, adds and modifies certain disclosure requirements for fair value measurements. Under the guidance, public companies will be required to disclose the range and weighted average used to develop significant unobservable inputs for Level 3 fair value measurements. The guidance is effective for all entities for fiscal years beginning after December 15, 2019 and for interim periods within those fiscal years, but entities are permitted to early adopt either the entire standard or only the provisions that eliminate or modify the requirements. The Group is currently in the process of evaluating the impact of the adoption of this guidance on its consolidated financial statements. Improvements to Accounting for Costs of Films and License Agreements for Program Materials. In March 2019, the FASB issued ASU 2019-02, Improvements to Accounting for Costs of Films and License Agreements for Program Materials, which improves U.S. GAAP by aligning the accounting for production costs of an episodic television series with the accounting for production costs of films by removing the content distinction for capitalization. In addition, ASU 2019-02 requires that an entity test a film or license agreement for program material within the scope of ASC 920-350 for impairment at a film group level when the film or license agreement is predominantly monetized with other films and/or license agreements. The presentation and disclosure requirements in ASU 2019-02 also increase the transparency of information provided to users of financial statements about produced and licensed content. This update will be effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. Early adoption is permitted. The Group does not expect the adoption to have a material impact on its consolidated financial statements. |

2010 share incentive plan In December 2010, the Group adopted a share incentive plan, which is referred to as the 2010 Share Option Plan (“the 2010 Plan”). The purpose of the plan is to attract and retain the best available personnel by linking the personal interests of the members of the board, employees, and consultants to the success of the Group’s business and by providing such individuals with an incentive for outstanding performance to generate superior returns for our shareholders. Under the 2010 Plan, the maximum number of shares in respect of which options, restricted shares, or restricted share units may be granted is 26,822,828 shares (excluding the share options previously granted to the directors who are the founders of the Company). The amount of shares available for such grants as of December 31, 2018 is 8,137,963. Options under the 2010 Plan were granted with exercise prices denominated in the USD, which is the functional currency of the Company. The maximum term of any issued stock option is seven or ten years from the grant date. Stock options granted to employees and officers vest over a four-year schedule as stated below:
Stock options granted to directors were subject to a vesting schedule of approximately 32 months. All share-based payments to employees are measured based on their grant-date fair values. Compensation expense is recognized on a straight-line basis over the requisite service period. In November 2014, the Company issued to a depositary bank for American Depositary Shares, 10,000,000 common shares, which were reserved for the future exercise of share options or vesting of restricted shares. 20,000 and 60,000 restricted shares were issued to non-employees and vested as of December 31, 2017 and 2018. The following table summarizes the share option activities for the years ended December 31, 2016, 2017 and 2018:
A summary of the restricted shares activities under the 2010 Plan for the years ended December 31, 2016, 2017 and 2018 is presented below:
Forfeitures are estimated at the time of grant. If necessary, forfeitures are revised in subsequent periods if actual forfeitures differ from those estimates. Based upon the Company’s historical and expected forfeitures for stock options granted, the directors of the Company estimated that its future forfeiture rate would be 20% for employees and nil for directors and advisors. The aggregate intrinsic value in the table above represents the difference between the estimated fair value of the Company’s common shares as of December 31, 2017 and 2018 and the exercise price. Total fair values of share options vested as of December 31, 2017 and 2018 were USD 6,963,000. As of December 31, 2017, there were USD 167,000 of unrecognized share-based compensation costs related to share options, which were expected to be recognized over a weighted-average vesting period of 4.64. As at December 31, 2018, there was no unrecognised share-based compensation costs related to share options. To the extent the actual forfeiture rate is different from the Company’s estimate, the actual share-based compensation related to these awards may be different from the expectation. All restricted shares granted to senior officers are measured based on their grant-date fair values. Compensation expense is recognized on a straight-line basis over the requisite service period. As of December 31, 2018, total unrecognized compensation expense relating to the restricted shares was USD 12,347,000. 2013 share incentive plan In November 2013, the Group adopted a share incentive plan, which is referred to as the 2013 Share Incentive Plan (“the 2013 Plan”).

Under the current laws of the Cayman Islands, the Company is not subject to tax on income or capital gains. Additionally, upon payment of dividends by the Company to its shareholders, no Cayman Islands withholding tax will be imposed.
The PRC enterprise income tax is calculated based on the taxable income determined under the PRC laws and accounting standards. Under the Corporate Income Tax (“CIT”) Law, which became effective on January 1, 2008, foreign invested enterprises and domestic enterprises are subject to a unified CIT rate of 25%. In accordance with the implementation rules of the CIT Law, a qualified “High and New Technology Enterprise” (“HNTE”) is eligible for a preferential tax rate of 15% and a “Software Enterprise” (“SE”) is entitled exemption from income taxation for the first two years, counting from the year the enterprise makes profit, and reduction half for the next three years. Shenzhen Xunlei has been recognized as HNTE and entitled to preferential tax rate of 15% for the years ended December 31, 2016, 2017 and 2018. Onething and Wangwenhua have been recognized as HNTE and entitled to preferential tax rate of 15% for the year ended December 31, 2018. Xunlei Computer was exempted from EIT for two years commencing from 2013, its first year of profitable operation after offsetting prior years’ tax losses, followed by a 50% reduction for the next three years. During the years ended December 2016 and 2017, Xunlei Computer was eligible for a 50% deduction from a preferential tax rate of 15%. Xunlei Computer has been recognized as HNTE and entitled to preferential tax rate of 15% for the year ended December 31, 2018. According to a policy of the PRC State tax bureau, enterprises that engage in research and development activities are entitled to claim 175% of the research and development expenses incurred in a year as tax deductible expenses in determining their tax assessable profits for that year (“R&D Super Deduction”) during the period from January 1, 2018 to December 31, 2020. Shenzhen Xunlei has been claiming R&D Super Deduction in ascertaining its tax assessable profits. The other PRC subsidiaries and Consolidated VIEs are subject to a 25% EIT rate. In addition, according to the EIT Law and its implementation rules, foreign enterprises, which have no establishment or place in the PRC but derive dividends, interest, rents, royalties and other income (including capital gains) from sources in the PRC are subject to PRC withholding tax, or WHT, at 10% (a further reduced WHT rate may be available according to the applicable double tax treaty or arrangement). The 10% WHT is generally applicable to any dividends to be distributed from Giganology Shenzhen and Xunlei Computer to the Company out of any profits of Giganology Shenzhen and Xunlei Computer derived after January 1, 2008. Up to December 31, 2018, both Giganology Shenzhen and Xunlei Computer did not declare any dividend to the parent company and have determined that they have no present plan to declare and pay any dividends. The Group currently plans to continue to reinvest its subsidiaries’ undistributed earnings, if any, in its operations in China indefinitely. Accordingly, no withholding income tax was accrued or required to be accrued for the years ended December 31, 2016, 2017 and 2018. Moreover, the current EIT Law treats enterprises established outside of China with “effective management and control” located in the PRC as PRC resident enterprises for tax purposes. The term “effective management and control” is generally defined as exercising overall management and control over the business, personnel, accounting, properties, etc. of an enterprise. The Company, if considered a PRC resident enterprise for tax purposes, would be subject to the PRC EIT at the rate of 25% on its worldwide income for the period after January 1, 2008. As of December 31, 2018, the Company has not accrued for PRC tax on such basis. The Company will continue to monitor its tax status. The current and deferred portions of income tax expense included in the consolidated statements of operations are as follows:
The aggregate amount and per share effect of the tax holidays are as follows:
The reconciliation of total tax benefit computed by applying the respective statutory income tax rates to pre-tax loss is as follows:
The tax effects of temporary differences that give rise to the deferred tax assets and liabilities balances at December 31, 2017 and 2018 are as follows:
Note a: As of December 31, 2018, the Group had tax loss carryforwards of USD 10,151,000, which can be carried forward to offset future taxable income. The net operating tax loss carryforwards will begin to expire as follows:
Note b: As at December 31, 2017 and 2018, the deferred tax assets and liabilities balances are expected to be recoverable as follows: Deferred tax assets
Deferred tax liabilities
Movement of valuation allowance is as follows:
In 2017, valuation allowance was provided for net operating loss carryforwards of Xunlei Networking Technologies (Beijing) Co., Ltd., Xunlei Games, Onething, Beijing Xunjing and Crystal Interactive because it was more likely than not that such deferred tax assets will not be realized based on the Group's estimate of their future taxable income, and the fact that the five entities were not included in the tax strategy plan. In 2018, valuation allowance was provided for net operating loss carryforwards of Onething, Xunlei Games, Beijing Xunjing and Crystal Interactive because it was more likely than not that such deferred tax assets will not be realized based on the Group's estimate of Onething’s future taxable income. As of December 31, 2018, the tax returns of the Group’s subsidiaries, VIE and its subsidiaries since their respective dates of incorporation are still open to examination. |

| Fair value measurements | 23. Fair value measurements Effective January 1, 2008, the Group adopted ASC 820-10, Fair Value Measurements and Disclosures, which defines fair value, establishes a framework for measuring fair value and expands financial statement disclosures about fair value measurements. Although adoption did not impact the Group’s consolidated financial statements, ASC 820-10 requires additional disclosures to be provided on fair value measurements. ASC 820-10 establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows: Level 1—Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets Level 2—Include other inputs that are directly or indirectly observable in the marketplace or based on quoted price in markets that are not active Level 3—Unobservable inputs which are supported by little or no market activity and are significant to the overall fair value measurement ASC 820-10 describes three main approaches to measuring the fair value of assets and liabilities: (1) market approach; (2) income approach and (3) cost approach. The market approach uses prices and other relevant information generated from market transactions involving identical or comparable assets or liabilities. The income approach uses valuation techniques to convert future amounts to a single present value amount. The measurement is based on the value indicated by current market expectations about those future amounts. The cost approach is based on the amount that would currently be required to replace an asset. The following table sets forth the financial instruments, measured at fair value, by level within the fair value hierarchy as of December 31, 2017 and 2018.

Capital commitments As at December 31, 2018, the Group has unconditional purchase obligations for switchboards, servers, office software and construction in progress that had not been recognized in the amount of USD 23,169,000.
Litigation The Group is involved in a number of cases pending in various courts. These cases are substantially related to alleged copyright infringement as well as routine and incidental matters to its business, among others. Adverse results in these lawsuits may include awards of damages and may also result in, or even compel, a change in the Group’s business practices, which could impact the Group’s future financial results. The Group had incurred USD 1,669,000, USD 9,453,000 and USD 4,667,000 legal and litigation related expenses for the years ended December 31, 2016, 2017 and 2018, respectively. Up to April 29, 2019, which is the date when the consolidated financial statements were issued, the Group had 46 lawsuits pending against the Group with an aggregate amount of claimed damages of approximately RMB 81.2 million (USD 12.3 million) which occurred before December 31, 2018 (2017: RMB 112 million (USD 16.76 million)). Of the 46 pending lawsuits, 42 lawsuits were relating to the alleged copyright infringement in the PRC. The Group had accrued for USD 3,846,000 litigation related expenses in ‘‘Accrued liabilities and other payables’’ in the consolidated balance sheet as of December 31, 2018 (2017: USD 1,755,000), which is the most probable and reasonably estimable outcome. The Group estimated the litigation compensation based on judgments handed down by the court, out-of-court settlements of similar cases as well as advices from the Group’s legal counsel. The Group is in the process of appealing certain judgments for which the losses had been accrued. Although the results of unsettled litigation and claims cannot be predicted with certainty, the Group does not expect that the outcome of the 46 lawsuits will result in the amounts accrued materially different from the range of reasonably possible losses. In the opinion of management, there was not at least a reasonable possibility the Company may have incurred a material loss, or a material loss in excess of a recorded accrual, with respect to loss contingencies for asserted legal and other claims. However, the outcome of litigation is inherently uncertain. If one or more of these legal matters were resolved against the Company in a reporting period for amounts in excess of management’s expectations, the Company’s consolidated financial statements for that reporting period could be materially adversely affected. In May 2014, the Group entered into a content protection agreement with the Motion Picture Association of America, Inc., or MPAA, and its members, which are six major U.S. entertainment content providers. In that agreement, the Group agreed to implement a comprehensive system of measures designed to prevent unauthorized downloading of and access to such content providers’ works. Despite the fact that the Group put in place preventive measures, the Group may still be subject to copyright infringement suits. In January 2015, a number of MPAA member studios filed 28 copyright infringement lawsuits against the Group on 28 video products in the Shenzhen Nanshan District Court in China. The court combined these cases into two cases for trial and entered a judgment on both cases on August 21, 2017. The court held, among others, that the Group infringed the plaintiffs’ copyright on 28 video products and were required by the court to compensate the plaintiff for a total of RMB 1.4 million (USD 0.2 million). The Group and MPAA had withdrawn the lawsuit filed with the appellate court and the Group has paid a total of RMB 1.4 million (USD 0.2 million) to MPAA in accordance with the judgement entered by Shenzhen Nanshan District Court in 2018.In addition, two putative shareholder class action lawsuits have been filed in the United States District Courts for the Southern District of New York against the Company and certain current and former officers and directors of the Company. Purporting to sue on behalf of all investors who purchased or acquired Xunlei stock from October 10, 2017 to January 11, 2018, plaintiffs allege that certain statements regarding OneCoin in the Company’s press releases and on a quarterly investor call were false and misleading because, among other things, they failed to disclose that OneCoin was a disguised “initial coin offering” and “initial miner offering” and constituted “unlawful financial activity.” Plaintiffs seek to recover under Sections 10(b) and 20(a) of the U.S. Securities Exchange Act of 1934 and Rule 10b-5 thereunder. On April 12, 2018, the court consolidated the actions under the caption In re Xunlei Limited Securities Litigation , No. 18-cv-467 (RJS) and appointed lead plaintiffs who filed a consolidated amended compliant on June 4, 2018. The Company filed a motion to dismiss the amended compliant on August 3, 2018. Although legal proceedings are inherently uncertain and their results cannot be predicted, the Group has not been, nor are the Group currently a party to or aware of, any legal proceeding, investigation or claim that, in the view of management, is likely to materially and adversely affect the business, financial position or results of operations. |

| Certain risks and concentration |
PRC regulations Current PRC laws and regulations place certain restrictions on foreign ownership of companies that engage in internet businesses, including the provision of online video and online advertising services. Specifically, foreign ownership in an internet content provider or other value-added telecommunication service providers may not exceed 50%. The Group conducts its operations in China principally through contractual arrangements among Giganology Shenzhen, its wholly-owned PRC subsidiary, and Shenzhen Xunlei and its shareholders. Shenzhen Xunlei holds the licenses and permits necessary to conduct its resource discovery network, online advertising, online games and related businesses in China and hold various operating subsidiaries that conduct a majority of its operations in China. The Company conducts all of its operations in China through, Shenzhen Xunlei, a variable interest entity, which it consolidates as a result of a series contractual arrangements enacted. If the Company had direct ownership of Shenzhen Xunlei, it would be able to exercise its rights as a shareholder to effect changes in the board of directors of Shenzhen Xunlei, which in turn could effect changes at the management level, subject to any applicable fiduciary obligations. However, under the current contractual arrangements, it relies on Shenzhen Xunlei and its shareholders’ performance of their contractual obligations to exercise effective control. In addition, its operating contract with Shenzhen Xunlei has a term of ten years, which is subject to Giganology Shenzhen’s unilateral termination right. None of Shenzhen Xunlei or its shareholders may terminate the contracts prior to the expiration date. Further, the Group believes that the contractual arrangements among Giganology Shenzhen, Shenzhen Xunlei and its shareholders are in compliance with PRC law and are legally enforceable. However, the Chinese government may issue from time to time new laws or new interpretations on existing laws to regulate this industry. Regulatory risk also encompasses the interpretation by the tax authorities of current tax laws, and the Group’s legal structure and scope of operations in the PRC, which could be subject to further restrictions resulting in limitations on the Company’s ability to conduct business in the PRC. The PRC government may also require the Company to restructure the Group’s operations entirely if it finds that its contractual arrangements do not comply with applicable laws and regulations. Furthermore, it could revoke the Group’s business and operating licenses, require it to discontinue or restrict its operations, restrict its right to collect revenues, block its website, require it to restructure its operations, impose additional conditions or requirements with which the Group may not be able to comply, or take other regulatory or enforcement actions against the Group that could be harmful to its business. The imposition of any of these penalties may result in a material and adverse effect on the Group’s ability to conduct the Group’s business. In addition, if the imposition of any of these penalties causes the Group to lose the rights to direct the activities of the VIE and its subsidiaries or the right to receive their economic benefits, the Group would no longer be able to consolidate the VIE. The Group does not believe that any penalties imposed or actions taken by the PRC Government would result in the liquidation of the Company, Giganology Shenzhen or Shenzhen Xunlei. The aggregate loss and distributable reserve of VIE and VIE’s subsidiaries amounted to approximately USD 32,222,000 and USD 67,747,000 respectively as of December 31, 2017 and 2018, which has been included in the consolidated financial statements. As stated above, Shenzhen Xunlei holds assets that are important to the operation of the Group’s business, including patents for proprietary technology, related domain names and trademarks. If Shenzhen Xunlei or its subsidiaries falls into bankruptcy and all or part of its assets become subject to liens or rights of third-party creditors, the Group may be unable to conduct its business activities in China, which could have a material adverse effect on the Group’s future financial position, results of operations or cash flows. However, the Group believes this is a normal business risk many companies face. The Group will continue to closely monitor the financial conditions of Shenzhen Xunlei and its subsidiaries. Shenzhen Xunlei and its subsidiaries’ assets comprise both recognized and unrecognized revenue-producing assets. The recognized revenue-producing assets include intangible assets, purchased property and equipment. The balances of these assets held by the VIE and its subsidiaries are included in “property and equipment, net” and “intangible assets, net” in the consolidated balance sheet and specifically in the VIE table on the following page. The unrecognized revenue-producing assets mainly consist of license, patents, trademarks, and domain names which are not recorded in the financial statement as they didn’t meet the recognition criteria set in ASC 350-30-25. The licenses stated above primarily consist of licenses that grant the VIE and its subsidiaries the right to produce and broadcast internet, radio, and television programs. One of them is the ICP licenses as described in note 1. As of December 31, 2018, Shenzhen Xunlei and its subsidiaries held patents granted in the PRC and in the United States. Presently, patent applications are being examined by the State Intellectual Property Office of the PRC and also patent application is being reviewed by the United States Patent and Trademark Office. As of December 31, 2018, Shenzhen Xunlei and its subsidiaries have applied to register trademarks, of which the Company has received registered trademarks in different applicable trademark categories including registered with World Intellectual Property Organization. The following consolidated financial information of the Group’s VIE and its subsidiaries from continuing operations was included in the accompanying consolidated financial statements, before elimination of balances with the Company and its subsidiaries, as of and for the years ended:
Foreign exchange risk The Group’s financing activities are denominated mainly in USD. The RMB is not freely convertible into foreign currencies. Remittances of foreign currencies into the PRC and exchange of foreign currencies into the RMB require approval by foreign exchange administrative authorities and certain supporting documentation. The State Administration for Foreign Exchange, under the authority of the People’s Bank of China, controls the conversion of RMB into other currencies. The revenues and expenses of the Company’s subsidiaries, consolidated VIE and its subsidiaries are generally denominated in RMB and their assets and liabilities are denominated in RMB. Concentration of customer risk The top 10 customers accounted for 18%, 27% and 23% of the net revenues for the years ended December 31, 2016, 2017 and 2018, respectively. Credit risk As of December 31, 2017 and 2018, substantially all of the Group’s cash and cash equivalents were held at reputable financial institutions in the jurisdictions where the Group and its subsidiaries are located. The Group believes that it is not exposed to unusual risks as these financial institutions have high credit quality. The Group has not experienced any losses on its deposits of cash and cash equivalents. Prior to entering into sales agreements, the Group performs credit assessments of its customers to assess their credit history. Further, the Group has not experienced any significant bad debts with respect to its accounts receivable for the years ended December 31, 2016 and 2017, the addition of allowance for doubtful accounts for the year ended December 31, 2018 was mainly arisen from the CDN service to a customer. Restricted net assets Relevant PRC laws and regulations permit payments of dividends by the Company’s subsidiaries, VIE and VIE’s subsidiaries in China only out of their retained earnings, if any, as determined in accordance with PRC accounting standards and regulations. In addition, the Company’s subsidiaries, VIE and VIE’s subsidiaries in China are required to make certain appropriation of net after-tax profits or increase in net assets to the statutory surplus fund (see Note 2(bb)) prior to payment of any dividends. As a result of these and other restrictions under PRC laws and regulations, the Company’s subsidiaries, VIE and VIE’s subsidiaries in China are restricted in their ability to transfer their net assets to the Company in terms of cash dividends, loans or advances, which restricted portion amounted to USD 142,487,000 and USD 144,433,000 as of December 31, 2017 and 2018, respectively. 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 the Company’s subsidiaries, VIE and a VIE’s subsidiaries in China due to changes in business conditions, to fund future acquisitions and development, or merely to declare and pay dividends to make distributions to shareholders. |

| Summary of significant accounting policies [Abstract] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Basis of presentation and use of estimates |
The consolidated financial statements of the Group have been prepared in accordance with accounting principles generally accepted in the United States of America (‘‘U.S. GAAP’’). Significant accounting policies followed by the Group in the preparation of the accompanying consolidated financial statements are summarized below. The Restructuring was accounted for at historical costs. The assets and liabilities of Shenzhen Xunlei are consolidated in the Company’s financial statements at carryover basis. The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the accompanying consolidated financial statements and related disclosures. Actual results could differ materially from these estimates. Significant accounting estimates reflected in the Group’s consolidated financial statements mainly include allowance for doubtful accounts, valuation allowance of deferred tax assets, sales rebate to advertising agencies, amortization period of online game revenue, amortization of content copyrights, fair value of content copyrights exchange, impairment assessment of goodwill and impairment assessment of long-lived assets. In addition, the Group uses assumptions in a valuation model to estimate the fair value of share options granted, warrants issued and underlying common shares. Management bases the estimates on historical experience and on various other assumptions that are believed to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities. Actual results could differ from these estimates. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Consolidation |
The consolidated financial statements include the financial statements of the Company, its subsidiaries, VIE for which the Company is the primary beneficiary and its subsidiaries. All significant transactions and balances among the Company, its subsidiaries, VIE and its subsidiaries have been eliminated upon consolidation. A subsidiary is an entity in which the Company, directly or indirectly, controls more than one-half of the voting power, or has the power to appoint or remove the majority of the members of the board of directors to cast majority of votes at meetings of the board of directors or to govern the financial and operating policies of the investee under a statute or agreement among the shareholders or equity holders. An entity is considered to be a VIE if the entity’s equity holders do not have the characteristics of a controlling financial interest or do not have sufficient equity at risk for the entity to finance its activities without additional subordinated financial support from other parties. The Group consolidates entities for which the Company is the primary beneficiary if the entity’s other equity holders do not have the characteristics of a controlling financial interest or do not have sufficient equity at risk for the entity to finance its activities without additional subordinated financial support from other parties. In determining whether the Company or its subsidiary is the primary beneficiary of a VIE, the Company considered whether it has the power to direct activities that are significant to the VIE’s economic performance, including the power to appoint senior management, right to direct company strategy, power to approve capital expenditure budgets, and power to establish and manage ordinary business operation procedures and internal regulations and systems. Management has evaluated the contractual arrangements among Giganology Shenzhen, Shenzhen Xunlei and its shareholders and concluded that Giganology Shenzhen receives all of the economic benefits and absorbs all of the expected losses from Shenzhen Xunlei and has the power to direct the aforementioned activities that are significant to Shenzhen Xunlei’s economic performance, and is the primary beneficiary of Shenzhen Xunlei. Therefore, Shenzhen Xunlei and its subsidiaries’ results of operation, assets and liabilities have been included in the Group’s consolidated financial statements. Management monitors the regulatory risk associated with these contractual arrangements. See Note 26 for further discussion. Non-controlling interests represent the portion of the net assets of a subsidiary attributable to interests that are not owned by the Company. The non-controlling interests are presented in the consolidated balance sheets, separately from equity attributable to the shareholders of the Company. Non-controlling interests in the results of the Group is presented on the face of the consolidated statements of comprehensive income as an allocation of the total income or loss for the year between non-controlling shareholders and the shareholders of the Company. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Discontinued operations |
When disposals that represent a strategic shift that has (or will have) a major effect on the entity’s results and operations would qualify as discontinued operations. Discontinued operations are reported when a component of an entity comprising operations and cash flows that can be clearly distinguished, operationally and for financial reporting purposes, from the rest of the entity is classified as held for disposal or has been disposed of, if the component either (1) represents a strategic shift or (2) have a major impact on an entity’s financial results and operations. Examples include a disposal of a major geographical location, line of business, or other significant part of the entity, or disposal of a major equity method investment. In the consolidated statement of comprehensive income, result from discontinued operations is reported separately from the income and expenses from continuing operations and prior periods are presented on a comparative basis. Cash flows for discontinuing operations are presented separately in note 3. In order to present the financial effects of the continuing operations and discontinued operations, revenues and expenses arising from intra-group transactions are eliminated except for those revenues and expenses that are considered to continue after the disposal of the discontinued operations. Non-current assets or disposal groups are classified as held for sale assets when the carrying amount is to be recovered principally through a sale transaction rather than through continuing use. For this to be the case, the asset or disposal group must be available for immediate sale in its present condition subject only to terms that are usual and customary for sale of such assets or disposal groups and the sale must be highly probable. Non-current assets classified as held for sale and disposal groups are measured at the lower of their carrying or fair value less costs to sell. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Foreign currency translation |
The Company’s reporting and functional currency is the United States Dollar (‘‘USD’’). Xunlei BVI and Xunlei HK’s functional currency is the USD. The functional currency of other subsidiaries, VIE and its subsidiaries located in the PRC is the Renminbi (‘‘RMB’’), which is their respective local currency. Transactions denominated in foreign currencies are remeasured into the functional currency at the exchange rates prevailing on the transaction dates. Financial assets and liabilities denominated in foreign currencies are remeasured into the functional currency using the applicable exchange rates prevailing at the balance sheet date. The resulting exchange gains and losses from foreign currency transactions are included in other income (loss) within the consolidated statements of comprehensive income. The Company uses the monthly average exchange rate for the year and the exchange rates at the balance sheet date to translate the operating results and financial position, respectively, of its subsidiaries whose functional currency is other than the USD. The resulting translation differences are recorded in cumulated translation adjustments, a component of shareholders’ equity. The exchange rate used is released by Chinese State Administration of Foreign Exchange. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Cash and cash equivalents |
Cash and cash equivalents include cash on hand, cash in bank and time deposits placed with banks or other financial institutions, which have original maturities of three months or less and are readily convertible to known amounts of cash. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Short-term investments |
Short-term investments include deposits placed with banks with original maturities of more than three months but less than one year and investments in financial instruments with a variable interest rate indexed to the performance of underlying assets. In accordance with ASC 825 Financial Instruments , for investments in financial instruments with a variable interest rate indexed to performance of underlying assets, the Group 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. Interest generated from short term investments are recorded when interest payments are received at the maturity date. It is recorded as “other income” on the statement of comprehensive income and measured based on the actual amount of interest the Group received. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Fair value of financial instruments |
The Group’s financial instruments consist principally of cash and cash equivalents, short-term investments, accounts receivable, other receivables, amounts due from/(to) related parties, accounts payable, and other payables. The carrying value of these balances, with the exception of short-term investments (see note 2 (f)), approximates their fair value due to the current and short term nature of these balances. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Accounts receivable, net |
Accounts receivable are presented net of allowance for doubtful accounts. The Group evaluates the creditworthiness of each customer at the time when services are rendered and continuously monitor the recoverability of the accounts receivable. The Group uses specific identification method in providing for bad debts when facts and circumstances indicate that collection is doubtful and a loss is probable and estimable. If the financial conditions of its customers were to deteriorate, resulting in an impairment of their ability to make payments, additional allowances might be required. The allowance for doubtful accounts is based on the best facts available and is re-evaluated and adjusted on a regular basis as additional information is received. Some of the factors that the Group considers in determining whether a bad debt allowance is recorded on an individual customer are: 1) the customer's past payment history and whether it fails to comply with its payment schedule; 2) whether the customer is in financial difficulty due to economic or legal factors; 3) a significant dispute with the customer has occurred; 4) the objective evidence which indicates non-collectability of the accounts receivable. The allowances provided for Accounts Receivable from continuing operations as of December 31, 2017 and 2018 were USD 31,000 and USD 7,709,000, respectively. If the Group determines that an allowance is needed for a customer, the Group will discontinue business with it unless they start to resume payment. The accounts receivable is written-off when the Group ceases to pursue collection. Any changes in the estimates may cause the Group's operating results to fluctuate. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Inventories |
Inventories are stated at the lower of cost or net realizable value. Cost is determined using actual cost on a weighted average basis. Net realizable value is the amount that can be realized from the sale of the inventory in the normal course of business after allowing for the costs of realization. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Long-term investments |
The Group holds investments in privately held companies. Prior to adopting ASU 2016-01, Financial Instruments on January 1, 2018, for those investments over which the Group does not have significant influence and without readily determined fair value, the Group carried the investment at cost and only adjusted for other-than-temporary declined in fair value and distribution of earnings that exceed the Group’s share of earnings. On January 1, 2018, the Group adopted ASU 2016-01, Financial Instruments , and started to measure long-term equity investments, other than equity method investments, at fair value through earnings. For those investments over which the Group does not have significant influence and without readily determinable fair value, the Group elected to record these investments at cost, less impairment, and plus or minus subsequent adjustments for observable price changes. Under this measurement alternative, changes in the carrying value of equity investments will be required to be made whenever there are observable price changes in orderly transactions for the identical or similar investment of the same issuer. Management regularly evaluates the impairment of long-term equity investments based on performance and financial position of the investee as well as other evidence of market value. Such evaluation includes, but it 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 recognised equal to the excess of the investment costs over its fair value at the end of each reporting period for which the assessment is made. The fair value would then become the new cost basis of investment. During the years ended December 31, 2016, 2017 and 2018 the Group recognized an impairment of USD 1.66 million, USD 0.6 million and USD 7.8 million, respectively. During the years ended December 31, 2016, 2017 and 2018, the Group recognized share of loss of equity investees of USD nil, USD 1.3 million and USD 0.3 million from Shenzhen Mojinggou Information Services Co., Ltd. (previously known as Xunlei Big Data Information Service Co., Ltd.) (“Big Data”) and Zhuhai Qianyou Technology, Co., Ltd. (“Zhuhai Qianyou”) respectively. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Property and equipment |
Property and equipment are stated at historical cost less accumulated depreciation and impairment loss, if any. Depreciation is calculated using the straight-line method over their estimated useful lives. Residual rate is determined based on the economic value of the asset at the end of the estimated useful life as a percentage of the original cost. If the Group commits to a plan to abandon a long-lived asset before the end of its previous estimated useful life, depreciation shall be revised to reflect a shortened useful life.
Repair and maintenance costs are expensed as incurred. Expenditures that substantially increase an asset’s useful life are capitalized. Upon sale or disposal, gain or loss on the 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 loss. The cost and related accumulated depreciation are removed from the balance sheets. |

| Goodwill |
Goodwill represents the excess of the purchase consideration over the fair value of the identifiable tangible and intangible assets acquired and liabilities assumed from the acquired entity as a result of the Company’s acquisitions of interests in its subsidiaries and consolidated VIEs. Goodwill is not amortized but is tested for impairment on an annual basis, or more frequently if events or changes in circumstances indicate that it might be impaired. The Company first assesses qualitative factors to determine whether it is necessary to perform the two-step quantitative goodwill impairment test. In the qualitative assessment, the Company considers primary factors such as industry and market considerations, overall financial performance of the reporting unit, and other specific information related to the operations. Based on the qualitative assessment, if it is more likely than not that the fair value of each reporting unit is less than the carrying amount, the quantitative impairment test is performed. In performing the two-step quantitative impairment test, the first step compares the fair values of each reporting unit to its carrying amount, including goodwill. 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 the purposes of evaluating goodwill impairment and does not result in an entry to adjust the value of any assets or liabilities. Application of a goodwill impairment test requires significant management judgment, including the identification of reporting units, allocation of assets, liabilities and goodwill to reporting units, and determination of the fair value of each reporting unit. No goodwill impairment losses were recognized for the years ended December 31, 2016, 2017 and 2018 based on the impairment test performed by the Group. |

| Intangible assets |
Intangible assets, which include computer software, internal use software development costs, online game licenses, domain names, land use rights, trademarks, technology (including right-to-use), non-compete agreement and audio-visual license, are carried at cost less accumulated amortization and impairment loss, if any. Exclusive game licenses are amortized using the straight-line method over their licensing period of three years. Computer software, internal use software and domain name are amortized using the straight-line method over their estimated useful life of five years. Land use right is amortized using the straight-line method over their estimated useful life of thirty years. Audio-visual license acquired is amortized using the straight-line method over its estimated useful life of nine years. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Impairment of long-lived assets |
For other long-lived assets, the Group evaluates its long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may no longer be recoverable. The Group assesses the recoverability of the long-lived assets by comparing the carrying value of the long-lived assets to the estimated undiscounted future cash flows expected to be received from use of the assets and their eventual disposition at the lowest level of identifiable cash flows. Such assets are considered to be impaired if the sum of the expected undiscounted cash flows is less than the carrying amount of the assets. If the Group identifies an impairment, the carrying value of the asset will be reduced to its estimated fair value based on a discounted cash flow approach or, when available and appropriate, to comparable market values. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Commitments and contingencies |
In the normal course of business, the Group is subject to contingencies, such as legal proceedings and claims arising out of its business, that cover a wide range of matters. Liabilities for such contingencies are recorded when it is probable that a liability has been incurred and the amount of the assessment can be reasonably estimated. In regards to legal cost, the Group recorded such costs as incurred. Certain conditions may exist as of the date the financial statements are issued, which may result in a loss to the Group, but which will only be resolved when one or more future events occur or fail to occur. The Group’s management and its legal counsel assess such contingent liabilities, and such assessment inherently involves an exercise of judgment. In assessing loss contingencies related to legal proceedings that are pending against the Group or unasserted claims that may result in such proceedings, the Group, in consultation with its legal counsel, evaluates the perceived merits of any legal proceedings or unasserted claims as well as the perceived merits of the amount of relief sought or expected to be sought therein. If the assessment of a contingency indicates that it is probable that a material loss has been incurred and the amount of the liability can be estimated, then the estimated liability would be accrued in the Group’s financial statements. If the assessment indicates that a potentially material loss contingency is not probable, but is reasonably possible, or is probable but cannot be estimated, then the nature of the contingent liability, together with an estimate of the range of possible loss, if determinable and material, would be disclosed. |

| Operating leases |
Leases in which a significant portion of the risks and rewards of ownership are retained by the lessor are classified as operating leases. Payments made under operating lease are charged to the statements of comprehensive income on a straight-line basis over the period of the lease. |

| Revenue recognition |
The Group adopted ASC Topic 606 Revenue from Contracts with Customer (“ASC 606”), from January 1, 2018, using the modified retrospective method. Revenues for the year ended December 31, 2018 were presented under ASC 606, and revenues for the years ended December 31, 2017 and 2016 were not adjusted and continue to be presented under ASC Topic 605, Revenue Recognition. The core principle of the ASC 606 is an entity should recognize revenues 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. Adoption had no significant impact on the consolidated financial statements. Significant accounting policy and relevant disclosure have been updated hereinafter. Effective January 1, 2018, the Group evaluates and recognizes revenue based on the criteria set forth in ASC 606 by: Step 1: Identify the contract(s) with a customer Step 2: Identify the performance obligations in the contract Step 3: Determine the transaction price Step 4: Allocate the transaction price to the performance obligations in the contract Step 5: Recognize revenues when (or as) the entity satisfies a performance obligation Revenue is recognized when or as the control of the services or goods is transferred to the customer. Depending on the terms of the contract and the laws that apply to the contract, control of the services and goods may be transferred over time or at a point in time. A contract liability is the Group’s obligation to transfer goods or services to a customer for which the Group has received consideration (or an amount of consideration is due) from the customer. Contract costs includes incremental costs of obtaining a contract and costs to fulfil a contract. The Group generates revenues from various streams. Net revenues presented in the consolidated statements of loss represent revenues from service and product sales net off sales discount, value-added tax and related surcharges. The Group operates a prepaid virtual items system, under which, prepaid virtual items at fixed face value are sold to third parties. Virtual items purchased can be used to subscribe for membership or purchase of virtual items in online games and live streaming, as discussed below. Virtual items sold but not yet consumed by the users are recorded as “Receipts in advance from customers” and upon consumption, they are recognized as membership subscription, online game revenue and live streaming revenue according to the respective prescribed revenue recognition policies addressed below. The Group’s revenue recognition policies effective on the adoption date of ASC 606 are as follows:
The Group operates a VIP membership program where VIP members can have access to high speed online acceleration services, online streaming and other access privileges. The membership fee is time-based and is collected up-front from subscribers except in the cases when they elect to pay via their mobile operators. The membership fee is collected when the subscribers pay for the monthly phone bills. The terms of time-based subscriptions range from one month to twelve months, with the subscribers having the option to renew the contract. The receipt of subscription fee is initially recorded as contract liabilities. The Group satisfies its various performance obligations by providing services throughout the subscription period and revenue is recognized rateably over the period of subscription as services are rendered. Unrecognized portion beyond 12 months from balance sheet date is classified as a long-term liability. The Group evaluated the principal versus agent criteria and determined that the Group is the principal in the transaction and accordingly record revenue on a gross basis. In determining whether to report revenues gross for the amount of subscription revenue, the Group assesses whether it maintains the principal relationship with the VIP members, whether it bears the credit risk and whether it establishes prices for the end users. Service fees levied by online system, fixed phone line and mobile payment channels (‘‘Payment handling charges’’) are recorded as the cost of revenues in the same period as the revenue for the membership fee is recognized.
Advertising revenues are derived principally from arrangements where the a dvertisers pay to place their advertisements on the Group’s platform over a particular period of time. It includes multiple performance obligations, primarily for advertisements to be displayed in different spots at different times, placed under different formats including but are not limited to videos, banners, links, logos and buttons. Advertisements on the Group’s platform are generally charged on the basis of duration, and advertising contracts are signed to establish the fixed price and the advertising services to be provided. The Group enters into advertising contracts with third party advertising agencies that represents advertisers, as well as directly with advertisers. A typical contract term would range from a few days to 3 months. Both third party advertising agencies and direct advertisers are generally billed at the end of the display period and payments are due usually within 3 months. Where the Group’s customers purchase multiple advertising spaces with different display periods in the same contract, the Group allocates the total consideration to the various advertising elements based on their relative fair values and recognizes revenue for the different elements over their respective display periods. The Group determines the fair values of different advertising elements based on the prices charged when these elements were sold on a standalone basis. The Group recognizes revenue on the elements delivered and defers the recognition of revenue for the fair value of the undelivered elements until the remaining obligations have been satisfied. Where all of the elements within an arrangement are delivered uniformly over the agreement period, the revenue is recognized on a straight line basis over the contract period. Transactions with third party advertising agencies For contracts entered into with third party advertising agencies, the third party advertising agencies will in turn sell the advertising services to advertisers. Revenue is recognized ratably over the contract period of display. The Group provides sales incentives in the forms of discounts and rebates to third party advertising agencies based on purchase volume. As the advertising agencies are viewed as the customers in these transactions, revenue is recognized based on the price charged to the agencies, net of sales incentives provided to the agencies. Sales incentives are estimated and recorded at the time of revenue recognition based on the contracted rebate rates and estimated sales volume based on historical experience. Transactions with third party advertising platforms Xunlei began to cooperate with third party advertising platforms such as Guangdiantong and Baidu since the fourth quarter in 2015. In this business model, advertisers put their content on third party advertising platforms and platforms will dispatch the advertising content to Xunlei’s platforms by certain analysis systematically. As the third party advertising platforms are viewed as the customers in these transactions, revenue is recognized monthly based on the data publicized on third party platforms and the price charged to these advertising platforms. Transactions with advertisers The Group also enters into advertisement contracts directly with advertisers. Under these contracts, similar to transactions with third party advertising agencies, the Group recognizes revenue ratably over the contract period of display. The terms and conditions, including price, are fixed according to the contract between the Group and the advertisers. The Group also performs credit assessment of all advertisers prior to entering into contracts. Revenue is recognized based on the amount charged to the advertisers, net of discounts. The Group has estimated and recorded sales rebates provided to the agencies and advertisers of USD 15,000, USD 440,000 and USD 394,000 for the years ended December 31, 2016, 2017 and 2018, respectively.
The Group operates live streaming platform and users can purchase virtual gifts which they can then send to performers in the live streaming platform. The consumption of each virtual gift sold to users is considered as the performance obligation. The Group does not have further obligations to the user after the virtual gifts are consumed immediately or after the stated period for time-based items. The revenue from consumable item is recognized at fair value of the virtual items, as Xunlei is the principal in this arrangement, based on actual consumption of virtual items by the paying users. The revenue from time-based item is recognized over the duration of stated period of the item.
Online games comprise web games, mobile games and PC games. Users play games through the Group’s platform free of charge and are charged for purchases of virtual items including consumable and perpetual items, which can be utilized in the online games to enhance their game-playing experience. The utilization of the virtual item is considered performance obligation by the Group and revenue is allocated to each performance obligation on a relative stand-alone selling price basis, which are determined based on the prices charged to customers. Consumable items represent virtual items that can be consumed by a specific user within a specified period of time. Perpetual items represent virtual items that are accessible to the users’ account over the life of the online game. Pursuant to contracts signed between the Group and game developers, revenue from the sale of virtual items are shared based on a pre-agreed ratio for each game. The Group enters into both non-exclusive and exclusive licensing contracts with game developers. Non-exclusive game licensed contracts The games under non-exclusive licensed contracts are maintained, hosted and updated by the game developers. The Group mainly provides access to the platform and limited after-sale services to the game players. The determination of whether to record these revenues using the gross or net method is based on an assessment of various factors; the primary factors are whether the Group acts as the principal in offering services to the game players or as agent in the transaction, and the specific requirements of each contract. The Group determined that for non-exclusive game licensed arrangements, the third party game developers are the principal given that the game developers design and develop the game services offered, have reasonable latitude to establish prices of game virtual items, and are responsible for maintaining and upgrading the game content and virtual items. Accordingly, the Group records online game revenue, net of the portion remitted to the game developers. Given that online games are managed and administered by the game developers for non-exclusive licensed games, the Group does not have access to the data on the consumption details and the types of virtual items purchased by the game players. The Group has adopted a policy to recognize revenues relating to both consumable and perpetual items over the shorter of 1) estimated lives of the games and 2) the estimated lives of the user relationship with the Group, which were approximately one to ten months for the periods presented. Adjustments arising from the changes of estimated lives of virtual items are applied prospectively as such changes are resulted from new information indicating a change in the game player behavioral patterns. Exclusive licensing game contracts For exclusive licensing contracts with game developers, the games are maintained and hosted by the Group. Accordingly, the Group is determined to be the principal, the Group records online game revenue on a gross basis, with the amount remitted to the game developers reported as cost of revenue. Payment handling charges are recognized as cost of revenues when the related revenues are recognized. For exclusive licensed games which are maintained on the Group’s server, the Group has access to the data on the consumption details and types of virtual items purchased by the game players. The Group does not maintain information on consumption details of virtual items, and only have limited information related to the frequency of log-ons. Given that a substantial portion of the virtual items purchased by the game players in exclusive licensed games are perpetual items, management determined that it would be most appropriate to recognize revenue over the shorter of 1) estimated lives of the games and 2) the estimated lives of the user relationship with the Group, which were approximately one to six months for the periods presented. Revenues related to consumable items are recognized immediately upon consumption. Game players can purchase prepaid virtual items which can be used to purchase virtual items via online channels. The Group incurs service fees levied by those payment channels, and such payment expenses are recorded as the cost of revenues when the related revenues are recognized. For both non-exclusive and exclusive licensed games, the Group estimates the life of virtual items to be the shorter of the estimated lives of the games and the estimated lives of the user relationship. The estimated user relationship period is based on data collected from those users who have purchased virtual items. To estimate the life of the user relationship, the Group maintains a software system that captures the following information for each user: the date of first log-on, the date the user ceases to play the game and frequency of log-ons. The Group estimates the life of the user relationship to be the weighted average period from the first purchase of a virtual item to the date the user ceases to play the game based on the frequency of log-ons. To estimate the life of the games, the Group considers both games that they operate as well as games in the market that are of a similar nature. The Group categorizes these games by their nature, such as simulation games, role playing games and others, which appeal to players belonging to different demographics. The Group estimates that the life of each group of the games to be the average period from the date of launch for such games to the date the games are expected to be removed from the website or terminated altogether. When the Group launches a new game, they estimate the life of the game and user relationship based on lives of other similar games in the market until the new game establishes its own history. The Group also considers the game’s profile, attributes, target audience, and its appeal to players of different demographic groups in estimating the user relationship period. The consideration of user relationship with each online game is based on the Group’s best estimate that takes into account all known and relevant information at the time of assessment. Adjustments arising from the changes of estimated lives of virtual items are applied prospectively as such changes are resulted from new information indicating a change in the game player behavioral patterns. Any changes in the estimates of lives of virtual items may result in the Group’s revenues being recognized on a basis different from prior periods and may cause the Group’s operating result to fluctuate. The Group periodically assesses the estimated lives of the virtual items and any changes from prior estimates are accounted for prospectively. Any adjustments arising from changes in user relationship as a result of new information will be accounted as a change in accounting estimate in accordance with ASC 250 Accounting Changes and Error Corrections . The Group entered into a legally binding agreement to sell its web game business in December 2017. Web game revenue recognized from discontinued operations was USD 15,981,000, USD 11,428,000 and USD 656,000 for the years ended December 31, 2016, 2017 and 2018, respectively.
The Group enters into contracts with certain third party portals/websites in which the Group is obliged to redirect online traffic to these third party portals/websites. On a monthly basis, the Group receives data on the user traffic and the related monthly revenue from these third party portals/ websites. Under these programs, the Group recognizes its share of revenues based on contractual rates applied to user traffic redirected to the advertisements of the third parties.
As part of the Group’s cloud computing business, the Group engages in sale of OneThing Cloud. OneThing Cloud is a personal cloud hardware device. OneThing Cloud allows users to share their idle bandwidth with the Group, in exchange for LinkTokens. LinkTokens are not convertible into cash but can be redeemed for products and services offered in the LinkToken Mall and exchange for a limited number of other products and services under the terms determined by the corresponding operators. LinkTokens represent an obligation to deliver future services by the operators of LinkToken Mall and other platforms. The bandwidth shared by the users in exchange for LinkTokens is an identifiable benefit, of which the Group can reasonably estimate fair value. The benefit that the Group receives from user’s contribution of bandwidth is independent from OneThing Cloud that the Group sells to users. The sales of OneThing Cloud and receipt of excess bandwidth by the Group are considered separate transactions. Therefore, sales of OneThing Cloud are reported as revenue, while LinkTokens given in exchange for bandwidth are reported as bandwidth cost. The Group sells OneThing Cloud primarily through online e-commerce platforms, the performance obligation is satisfied when the item is dispatched to the end customers. The LinkTokens issued represent an obligation to deliver future services. Therefore, contract liabilities were recognized for all LinkTokens issued. Revenue will be recognized upon redemption of the LinkTokens, the fair value of which is measured by bandwidth costs divided by total number of LinkTokens issued. Breakage is taken into account based on historical experience. The core business principle of cloud computing is to collect idle uplink capacity from individuals with compensation, and sells to online video streaming platforms. On a monthly basis, the Group records the bandwidth it delivers and recognizes revenue from these online video streamers under contractual rates applied (price per GB of bandwidth multiplies total GBs of bandwidth per month). The cost of collecting idle bandwidth is recorded as bandwidth costs within cost of revenues upon the Group receives the idle bandwidth. Revenue is recognized net of return allowances when the products are delivered and title passes to customers. Return allowances, which reduce net revenues, are estimated based on historical experiences. Product warranties are estimated and recognized at the time the Company recognizes revenue. The warranty period is 1 year. The Company accrues warranty liabilities at the time of sale, based on historical and projected incident rates and expected future warranty costs. |

| Sales and marketing expenses |
Sales and marketing expenses comprise primarily of salary, benefits of sales and marketing personnel and external advertising and market promotion expenses. The external advertising and market promotion expenses from continuing operations amounted to approximately USD 6,666,000, USD 10,345,000 and USD 22,935,000 for the years ended December 31, 2016, 2017 and 2018, respectively. Shipping and handling fee is recorded in sales and marketing expenses. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| General and administrative expenses |
General and administrative expenses consist primarily of salary and benefits, professional service fees, legal expenses and other administrative expenses. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Research and development costs |
The Group incurred research and development costs to develop its downloading software. Costs incurred during the research phase are expensed as incurred. Costs incurred for the development of the downloading software prior to the establishment of technological feasibility, which is when a working model is available, are expensed when incurred. The development costs qualified for capitalization have been immaterial for the periods presented. The Group also incurred development costs in connection with an internal-use ERP software to further enhance management to monitor the business. While internal and external costs incurred during the preliminary project stage are expensed as incurred, costs relating to activities during the application development stages have been capitalized. During each of the three years ended December 31, 2018, no software development costs were capitalized as intangible assets. In addition, the Group incurred other research and development costs in relation to software used to support its operations. Any development costs qualified for capitalization were immaterial for the periods presented. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Taxation and uncertain tax positions |
Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statements’ carrying amounts of existing assets and liabilities and their respective tax bases and tax loss carry forwards. Deferred tax assets and liabilities are measured using enacted tax rates in effect for the year in which the difference is expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in the consolidated statement of operations in the period that includes the enactment date. A valuation allowance is provided to reduce the carrying amount of deferred tax assets if it is considered more likely than not that some portion, or all, of the deferred tax assets will not be realized. The estimation of future taxable income involves significant judgement and estimates. Based on management's estimated future taxable income, management concluded that it is more likely than not that the net operating losses carried forward can be utilized prior to their respective expiration dates. The Group adopted the guidance regarding uncertain tax positions and evaluated its open tax positions that exist in each jurisdiction for each reporting period. If an uncertain tax position is taken or expected to be taken in a tax return, the tax benefit from that uncertain position is recognized in the Group’s consolidated financial statements if it is more likely than not that the position is sustainable upon examination by the relevant taxing authority. The Group did not have any significant uncertain tax position and there was no effect on its financial condition or results of operations as a result of implementing the new guidance. The Group recognizes interest and penalties accrued on any unrecognized tax benefits as a component of income tax expense, if any. No significant interest and penalties were recorded in the years ended December 31, 2016, 2017 and 2018. Transition from PRC Business Tax to PRC Value Added Tax VAT payable on goods sold or taxable labor services provided by a general VAT taxpayer for a taxable period is the net balance of the output VAT for the period after crediting the input VAT for the period. In addition to the product revenues currently subject to VAT at a rate of 16 % (17 % before May 1, 2018), the Group’s advertising revenues, subscription revenue, online game revenue, revenue from cloud computing and live streaming revenue are now subject to VAT at a rate of 6%. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Retirement benefits |
Full-time employees of the Company’s subsidiaries, consolidated VIE and its subsidiaries in the PRC participate in a government mandated multi-employer defined contribution plan pursuant to which certain pension benefits, medical care, unemployment insurance, employee housing fund and other welfare benefits are provided to employees. Chinese labor regulations require that the subsidiaries and VIEs of the Company make contributions to the government for these benefits based on certain percentages of the employees’ salaries. The Group has no legal obligation for the benefits beyond the contributions made. The total amounts from continuing operations for such employee benefits, which are expensed as incurred, were USD 8,645,000, USD 10,123,000 and USD 12,501,000 for the years ended December 31, 2016, 2017 and 2018, respectively. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Share-based compensation |
The Group measures share-based compensation at the grant date based on the fair value of the award determined using the Black-Scholes option pricing model. As the Group has granted share options and restricted shares with service-only condition, the Group elected to recognize compensation costs net of estimated forfeitures on a straight line basis over the requisite service period, which is generally the same as the vesting period. The amount of compensation cost recognized at any date is at least equal to the portion of the grant-date value of the award that is vested at that date. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Government subsidies |
The Group receives subsidies from the local PRC government for general use or purchase of equipment. General-use subsidies which are not subject to any conditions or specific use requirements are recorded as subsidy income in the consolidated statements of operations. Subsidies for purchase of equipment are recorded as deferred government grant when received, and are recorded as other income over the expected useful life of the assets after the related equipment has been purchased. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Segment reporting |
The Group’s Chief Executive Officer has been identified as the chief operating decision maker (“CODM”), who reviews consolidated operating results of the Group when making decisions about allocating resources and assessing performance of the Group as a whole. The Group has internal reporting of revenue, cost and expenses that does not distinguish between segments, and reports costs and expense by nature as a whole. The Group does not distinguish between markets or segments for the purpose of internal reporting. Management has determined that the Group operates and manages its business as a single segment which is the operation of its online media platform, over 99% of revenues of the Group were derived from mainland China. An analysis of the different types of revenues for the years ended December 31, 2016, 2017 and 2018 are summarized as follows:
|
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Net loss per share |
Net basic loss per share is computed by dividing net loss attributable to holders of common shares by the weighted-average number of common shares outstanding during the year using the two class method. Using the two class method, net loss is allocated between common shares and other participating securities based on their participating rights. Net diluted loss per share is calculated by dividing net loss attributable to common shareholders as adjusted for the effect of dilutive common equivalent shares, if any, by the weighted-average number of common and dilutive common equivalents shares outstanding during the year. Dilutive equivalent shares are excluded from the computation of diluted loss per share if their effects would be anti-dilutive. Common share equivalents consist of the common shares issuable upon the conversion of the stock options, using the treasury stock method. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Comprehensive income |
Comprehensive income is defined as the change in equity of a Group during the period from transactions and other events and circumstances excluding transactions resulting from investments from shareholders and distributions to shareholders. Accumulated other comprehensive income, as presented on the accompanying consolidated balance sheets, consists of cumulative translation adjustment. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Profit appropriation and statutory reserves |
The Group’s subsidiaries, consolidated VIE and its subsidiaries incorporated in the PRC are required on an annual basis to make appropriations of retained earnings set at certain percentage of after-tax profit determined in accordance with PRC accounting standards and regulations (“PRC GAAP”). Appropriation to the statutory general reserve should be at least 10% of the after-tax net income determined in accordance with the legal requirements in the PRC until the reserve is equal to 50% of the entities’ registered capital. The Group is not required to make appropriation to other reserve funds and the Group does not have any intentions to make appropriations to any other reserve funds. The general reserve fund can only be used for specific purposes, such as setting off the accumulated losses, enterprise expansion or increasing the registered capital. Appropriations to the general reserve funds are classified in the consolidated balance sheets as statutory reserves. There are no legal requirements in the PRC to fund these reserves by transfer of cash to restricted accounts, and the Group does not do so. The following table presents the balances of registered capital, additional paid-in-capital and statutory reserves of entities within the Group incorporated in China as of December 31, 2017 and 2018 for the Group’s reporting purpose in China as determined under generally accepted accounting principles in China:
Relevant laws and regulations permit payments of dividends by the PRC subsidiaries and affiliated companies only out of their retained earnings, if any, as determined in accordance with respective accounting standards and regulations. Accordingly, the above balances are not allowed to be transferred to the Company in terms of cash dividends, loans or advances (See also Note 26). |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Dividends |
Dividends are recognized when declared. No dividends were declared for the years ended December 31, 2016, 2017 and 2018. The Group does not have any present plan to pay any dividends on common shares in the foreseeable future. The Group currently intends to retain the available funds and any future earnings to operate and expand its business. |

| Recent accounting pronouncements |
Leases. In February 2016, the Financial Accounting Standards Board (“FASB”) issued ASU 2016-02, Leases , which specifies the accounting for leases. For operating leases, ASU 2016-02 requires a lessee to recognize a right-of-use asset and a lease liability, initially measured at the present value of the lease payments, in its balance sheet. The standard also requires a lessee to recognize a single lease cost, calculated so that the cost of the lease is allocated over the lease term, on a generally straight-line basis. In addition, this standard requires both lessees and lessors to disclose certain key information about lease transactions. ASU 2016-02 is effective for publicly traded companies for annual reporting periods, and interim periods within those years, beginning after December 15, 2018. The Group adopted the new standard effective January 1, 2019 on a modified retrospective basis and will not restate comparative periods. The Group estimates approximately USD11.8 million and USD11.4 million would be recognized as total right-of use assets and total lease liabilities, respectively on the consolidated balance sheets as of January 1, 2019. The Group expects that net profit after tax will not be materially changed as a result of adopting the new rules. The adoption of new standard will also result in certain reclassification of operating cash flows and financing cash flows. Financial Instruments-Credit Losses. In June 2016, the FASB issued ASU 2016-13 , Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which requires the measurement and recognition of expected credit losses for financial assets held at amortized cost. ASU 2016-13 replaces the existing incurred loss impairment model with an expected loss methodology, which will result in more timely recognition of credit losses. ASU 2016-13 is effective for annual reporting periods, and interim periods within those years, beginning after December 15, 2019. The Group is currently in the process of evaluating the impact of the adoption of ASU 2016-13 on its consolidated financial statements. Simplifying the Test for Goodwill Impairment . In January 2017, the FASB issued ASU 2017-04 Simplifying the Test for Goodwill Impairment. The guidance removes Step 2 of goodwill impairment tests, which requires a hypothetical purchase price allocation. A goodwill impairment will now be the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. The guidance is to be adopted on a prospective basis for the annual or any interim goodwill impairment tests beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The Group does not expect the adoption to have a material impact on its consolidated financial statements. Compensation—Stock Compensation . In June 2018, the FASB issued ASU 2018-07, Compensation—Stock Compensation (Topic 718): Improvement to Nonemployee Share-based Payment Accounting to amend the accounting for share-based payment awards issued to nonemployees. Under the revised guidance, the accounting for awards issued to nonemployees will be similar to the model for employee awards. The update is effective for public business entities for fiscal years beginning after December 15, 2018, including interim periods within that fiscal year. The Group adopted this new standard effective on January 1, 2019. The adoption of ASU 2018-07 did not have a material impact on the Group’s consolidated financial statements. Fair Value Measurement. In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement , which eliminates, adds and modifies certain disclosure requirements for fair value measurements. Under the guidance, public companies will be required to disclose the range and weighted average used to develop significant unobservable inputs for Level 3 fair value measurements. The guidance is effective for all entities for fiscal years beginning after December 15, 2019 and for interim periods within those fiscal years, but entities are permitted to early adopt either the entire standard or only the provisions that eliminate or modify the requirements. The Group is currently in the process of evaluating the impact of the adoption of this guidance on its consolidated financial statements. Improvements to Accounting for Costs of Films and License Agreements for Program Materials. In March 2019, the FASB issued ASU 2019-02, Improvements to Accounting for Costs of Films and License Agreements for Program Materials, which improves U.S. GAAP by aligning the accounting for production costs of an episodic television series with the accounting for production costs of films by removing the content distinction for capitalization. In addition, ASU 2019-02 requires that an entity test a film or license agreement for program material within the scope of ASC 920-350 for impairment at a film group level when the film or license agreement is predominantly monetized with other films and/or license agreements. The presentation and disclosure requirements in ASU 2019-02 also increase the transparency of information provided to users of financial statements about produced and licensed content. This update will be effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. Early adoption is permitted. The Group does not expect the adoption to have a material impact on its consolidated financial statements. |

- Definition Any certificate of deposit or savings account held by a bank or other financial institution for a short-term specified period of time. Because of their short-term, time deposits are considered highly liquid investments that are both readily convertible to known amounts of cash and so near their maturity that they present insignificant risk of changes in value because of changes in interest rates. Generally, only investments with original maturities of three months or less qualify under that definition. Original maturity means original maturity to the entity holding the investment. For example, both a three-month US Treasury bill and a three-year Treasury note purchased three months from maturity qualify as cash equivalents. However, a Treasury note purchased three-years ago does not become a cash equivalent when its remaining maturity is three months. Reference 1: http://fasb.org/us-gaap/role/ref/legacyRef

- Definition This item represents an other than temporary decline in value that has been recognized against an investment accounted for under the equity method of accounting. The excess of the carrying amount over the fair value of the investment represents the amount of the write down which is or was reflected in earnings. The written down value is a new cost basis with the adjusted value of the investment becoming its new carrying value subject to the equity accounting method. Evidence of a loss in value might include, but would not necessarily be limited to, absence of an ability to recover the carrying amount of the investment or inability of the investee to sustain an earnings capacity which would justify the carrying amount of the investment.
