C.Reasons for the Offer and Use of Proceeds Not applicable. D.Risk Factors An investment in our ADSs involves significant risks. You should carefully consider all of the information in this annual report, including the risksand uncertainties described below, before making an investment in our ADSs. Any of the following risks could have a material adverse effect on our business,financial condition and results of operations. In any such case, the market price of our ADSs could decline, and you may lose all or part of your investment. 5 Risks related to our business Our business model is currently undergoing significant innovation and transition, and our historical growth rate may not be indicative of our futureperformance and our new business may not be successful. We launched our then core product, Xunlei Accelerator, in 2004 and cloud acceleration subscription services in 2009 to enable users to quicklyaccess and consume digital media content. These cloud acceleration products have maintained nationwide popularity in the past few years. Coupled with ourcore products and services, we also provide a range of internet value-added services. Our business model currently is undergoing significant innovation andcontinued transition to mobile internet. We have also been putting efforts in the launch and expansion of new services and product offerings, such as cloudcomputing products and products based on blockchain technology. The evolving business model and expansion into the new services involve new risks andchallenges. The profitability of our new initiatives has yet to be proven. For example, although our mobile acceleration plug-in, has been officially adoptedby Xiaomi’s operating systems and installed on Xiaomi phones, we cannot assure you that we will be able to form significant business partnerships withmajor smartphone makers other than Xiaomi so as to achieve broader acceptance of the Xunlei mobile products. We may also not be able to maintain therapid growth of revenues from our mobile advertising, from which we generated revenues for the first time in the fourth quarter of 2015. As a result, ourmobile strategy may not be successful. We are also devoting significant energy and resources to continue to develop our ongoing innovation in crowdsourcing for idle uplink capacity andpotentially storage from our users, which we refer to as Project Crystal or our cloud computing project. Our cloud computing project targets to utilize ourusers’ computing power for capacity and storage in the same way our traditional acceleration products utilize users’ idle uplink establishing and indexingfiles. After years of financial and managerial investments in this project, we have seen a preliminary success on our efforts. Revenue generated from our cloudcomputing business accounted for 32.6% of our total revenue in 2017. However, substantial uncertainties on the future development of our cloud computingbusiness still exist and we cannot assure you as to its future prospects. For example, the technologies supporting our cloud computing business are relativelynew and are rapidly evolving. Any failure in our exploration and application of these new technologies could lead to unsatisfactory project outcomes andcould significantly and adversely impact our operating results. To further develop our cloud computing business and at the same time explore emergingblockchain technology, we launched OneThing Cloud, a hardware device of our cloud computing business, which can be used as remote downloader,personal cloud storage and file management device, and LinkToken, which is renamed from OneCoin, a type of digital tickets based on blockchaintechnology, in 2017. See “Item 4. Information on the Company—B. Business Overview—Our Platform—Cloud Computing” for more information. Thelaunch of these new products involves certain risks and uncertainties. For example, in connection with our OneThing Cloud and LinkToken, which isrenamed from OneCoin, two putative class action lawsuits have been filed in the United States District Courts for the Southern District of New York againstthe Company and certain of our current and former officers and directors, alleging that the defendants made material misstatements omissions on the premisethat they failed to disclose that OneCoin was a disguised “initial coin offering” and “initial miner offering” and constituted “unlawful financial activity.” OnApril 12, 2018, the court consolidated the actions under the caption In re Xunlei Limited Securities Litigation, No. 18-cv-467 (RJS). See “—We may besubject to claims or lawsuits outside of China, which could increase our risk of direct or indirect liabilities for our existing or future service offerings” formore details. In addition, there are also certain regulatory risks associated with our LinkToken. For more details, please see “—Our LinkToken may be subjectto various regulatory risks in China which may result in penalties that could have a material adverse effect on our business and results of operations.” If anyof the foregoing were to happen, other than administrative penalties we may be imposed, our business operations, financial results and the price of our ADSsmay be adversely affected. In addition to uncertainties of our new initiatives, our traditional PC-based download acceleration subscriptions also experienced declines, partlydue to the ongoing and intensified government scrutiny of internet content in China. Although we continue to enhance and update our products in order tomake them attractive to our subscribers, our efforts may not be successful. Our subscriber base decreased from 4.4 million as of December 31, 2014 to 4.3million as of December 31, 2017. See “—We may not be able to retain our large user base, convert our users into subscribers of our premium services ormaintain our existing subscribers.” and “—Risks Related to Doing Business in China— Regulation and censorship of information disseminated over theinternet in China have adversely affected our business and may continue to adversely affect our business, and we may be liable for the digital media contenton our platform.” Due to the abovementioned factors, our historical growth rate may not be indicative of our future performance and our new business initiative maynot be successful, and we cannot assure you that we will grow at the same rate as we did in the past, if at all. 6 Our business currently focuses on the PRC market. We may face additional risks and uncertainties if we expand our business into overseas markets inthe future. As we have very limited in operating our business in overseas markets, we may be unable to attract a sufficient number of users, fail to anticipatecompetitive conditions or face difficulties in operating effectively in overseas markets. In addition, trade barriers, such as import and export restrictions,customs duties and other taxes, competition law regimes and other trade restrictions, as well as other risks such as increased compliance costs or politicalinstability may also expose us to additional risks and uncertainties if we expand our business to overseas markets. Our LinkToken may be subject to various regulatory risks in China which may result in penalties that could have a material adverse effect on our businessand results of operations. In connection with our new efforts in the development of cloud computing and exploration of emerging blockchain technology, we also createdLinkToken in 2017 based on blockchain technology. See “Item 4. Information on the Company—B. Business Overview—Our Platform—Cloud Computing”for more information. The LinkToken is related to our cloud computing services. By voluntarily participating in our OneThing reward program while usingour OneThing Cloud device, users can be rewarded with LinkToken, which can be used to redeem for our product and services. LinkToken cannot betransferred among users in China. On September 4, 2017, six PRC regulatory agencies, namely People’s Bank of China, the Office of the Central LeadingGroup for Cyberspace Affairs, MIIT, State Administration for Industry and Commerce, China Banking Regulatory Commission, China Securities RegulatoryCommission, China Insurance Regulatory Commission, jointly promulgated the Announcement on Preventing Token Fundraising Risks, to strengthen theadministration of the initial coin offerings (“ICOs”) activities. Pursuant to the announcement, “token fundraising” is referred to as a process where fundraisers,issue or distribute so-called “cryptocurrencies” to investors who make financial contributions in the form of “virtual currencies” such as Bitcoin or Ether. Allfundraising activities through token issuance are prohibited. In addition, token trading platform should not engage in (i) the exchange between any statutorycurrency with tokens and “virtual currencies”, (ii) trade or trade as central counterparties the tokens or “virtual currencies”, and (iii) provide pricing,information agency or other services for tokens or “virtual currencies.” While being rewarded with LinkToken by using our OneThing Cloud, users do notmake financial contributions in any form of cryptocurrencies. LinkToken cannot be transferred among users in China. As a result, we do not believe ourLinkToken involves fundraising activities through token issuance, nor do we believe that we will be deemed as a token trading platform, which is operatedunder a completely different business model. However, we cannot assure you that relevant PRC authorities will have the same view with us and substantialuncertainties exist regarding the interpretation and implementation of relevant PRC laws and regulations. If relevant PRC authorities decide that ouroperation of LinkToken is not in compliance with current laws and regulations, regulatory restrictions may be imposed on us or we may even be required todiscontinue relevant business. In addition, the blockchain technology and other related technologies are evolving rapidly, new laws and regulations may beadopted from time to time by relevant PRC authorities to impose additional restrictions or require licenses or permits for the operation of businesses that aresimilar to our LinkToken. Were that to happen, we may be subject to additional regulatory risks and business and results of operations, as well as the price ofour ADSs may be adversely affected. We may not be able to retain our large user base, convert our users into subscribers of our premium services or maintain our existing subscribers. Our platform had approximately 145 million monthly unique visitors in December 2017 according to our internal record. If we are unable toconsistently provide our users with quality services and experience, if users do not perceive our service offerings to be of value, or if we introduce new oradjust existing features or change the mix of digital media content in a manner that is not favorably received by our users, we may not be able to retain ourexisting user base. Our number of subscribers experienced a decline in the past partly due to the intensified scrutiny over internet content from the Chinesegovernment, and may experience further downward pressure in the future. With a government campaign against inappropriate internet content launched inApril 2014, we have had to increase the monitoring of content on our platform. All the measures we adopt in response to increasing regulatory scrutiny maymaterially and adversely affect user experience on our platform and make our services less attractive to our subscribers, leading to a decline in the number ofsubscribers. We saw a reduction in the number of total subscribers of 4.4 million as of December 31, 2014, and permitted temporary suspension of services byabout 350,000 existing subscribers as of December 31, 2014. Although the permitted temporary suspension of services gradually reduced to 207,000 existingsubscribers as of December 31, 2017, such favorable trends may not sustain, and any increase in the number of subscribers may not necessarily lead to acorresponding increase in revenue. Similar government action or other forces may make it challenging for us to retain our user base, or may contribute to afurther decline in our user base, in the future. See “—Risks Related to Doing Business in China—Regulation and censorship of information disseminatedover the internet in China have adversely affected our business and may continue to adversely affect our business, and we may be liable for the digital mediacontent on our platform.” 7 In the long term, even without taking into account the abovementioned government restrictions, we cannot assure you that we would be able toretain our large user or subscriber base. For example, our efforts to provide greater incentives for our users to subscribe, including marketing activities tohighlight the value of differentiated subscriber-only services, such as Green Channel and Offline Accelerator, may not continue to succeed. Our subscribersmay stop their subscriptions or other spending on our products or services because we no longer serve their needs or if we are unable to offer a satisfying userexperience or successfully compete with current and new competitors in both retaining our existing subscribers and attracting new subscribers, which wouldadversely impact our business, results of operations and prospects. We face and expect to continue to face copyright infringement claims and other related claims, including claims based on content available through ourservices, which could be time-consuming and costly to defend and may result in damage awards, injunctive relief and/or court orders, divert ourmanagement’s attention and financial resources and adversely impact our business. Our success depends, in large part, on our ability to operate our business without infringing, misappropriating or otherwise violating third-partyrights, including third-party intellectual property rights. Internet, technology and media companies are frequently involved in litigations based onallegations of infringement of intellectual property rights, unfair competition, invasion of privacy, defamation and other violations of other parties’ rights. In May 2014, we 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, we agreed to implement a comprehensive system of measures designed toprevent unauthorized downloading of and access to such content providers’ works. After beginning the roll-out for several months, we suspendedimplementation of the filter but have identified and are in the process of implementing a new filter. Even with the implementation of a new filter, however,our copyright protection measures would not be able to fully protect us against copyright infringement suits. In January 2015, a number of MPAA memberstudios filed 28 copyright infringement lawsuits against us on 28 video products in the Shenzhen Nanshan District Court in China. The court combined thesecases into two cases for trial and entered a judgment on both cases on August 21, 2017. The court held, among others, that we infringed the plaintiffs’copyright on 13 of 28 video products and were required by the court to compensate the plaintiff for a total of RMB1.4 million. As of the date of this annualreport, those cases are awaiting decisions of appellate court. Although we expect that the outcome of these lawsuits would not have a material adverse effecton our financials, we cannot provide you with any estimate as to such outcome or assure you that it would not have material adverse impact upon ourbusiness. Even if we won the court ruling for these current proceedings or ultimately reached settlement with MPAA and the relevant members, we cannotassure you that any of these parties would not initiate other proceedings against us. Also see “Item 8. Financial Information—A. Consolidated Statements andOther Financial Information—Legal Proceedings.” In the ordinary course of our business, we receive, from time to time, written notices from third parties claiming that certain content and games in ournetwork or on one or more of our websites infringe their copyrights or the copyrights of third parties. These notices may threaten to take legal actions againstus or request us to cease distribution, marketing or displaying such content or games on our network or websites. Claims alleging copyright infringement orother claims arising from the content accessible through our distributed computing network, or on our websites or through our other services, such as thelegal proceeding initiated by MPAA members or any potential legal proceedings that may be initiated by, for example, the Motion Picture Association ofAmerica Inc., with or without merit, may lead to damage awards and/or court orders, diversion of our management’s attention and financial resources andnegative publicity affecting our brand and reputation, and therefore may adversely affect our results of operations and business prospects. In addition, asignificant number of these claims relate to content on Xunlei Kankan. We have completed our sale of Xunlei Kankan to a third party buyer in July 2015. Asa result, our exposure to claims in relation to intellectual property have significantly decreased, although we still expect to face a number of copyrightinfringement claims and other related claims in the future in relation to our other products and services. 8 We were subject to a number of lawsuits in China for alleged copyright infringements over the years, a number of which are still outstanding as ofthe date of this annual report. We can provide no assurance that we will be granted the judgements or awards in favor of us. In addition, these existing andfuture claims may divert our management’s attention and financial resources and adversely impact our business. The premium acceleration services and other value-added services we provide to our subscribers may expose us to additional copyright infringementclaims, which could materially and adversely affect our existing business model. We provide subscribers with limited space to temporarily store content downloaded on our servers for optimal acceleration performance. Subscribersmay also request our cloud servers to transmit a file on their behalf and upload it to their properties. See “Item 4. Information on the Company—B. BusinessOverview—Our Platform—Subscription services.” In addition, certain of our services allow users to upload files after they create accounts with us, convertingthe files into links and sharing such links with designated persons. We may be liable for transmitting or temporarily storing content or creating linksrepresenting content on behalf of our subscribers if such content infringes third-party intellectual property rights, and any such potential legal liabilitiescould materially and adversely affect our business. If we are unable to successfully capture and retain the growing number of mobile internet users or if we are unable to successfully monetize our mobileproducts, our business, financial condition and results of operations may be materially and adversely affected. An increasing number of users access our products and services through mobile devices, and the transition to mobile internet is a key part of ourcurrent business strategies. Products such as Xunlei Accelerator are now available to users from PCs as well as mobile devices, and we intend to continueexpanding the number of mobile products we offer. An important element of our strategy to transition to mobile internet is to continue to further developfeatures for our mobile products and to develop new mobile products to capture a greater share of the growing number of users that access internet servicessuch as ours through mobile devices. For example, we developed Mobile Xunlei, which allows users to search, download and consume digital media contenton their mobile devices in a user friendly way. As new laptops, mobile devices and operating systems are continually being released, it is difficult to predictthe problems we may encounter in developing our products for use on these devices and operating systems, and we may need to devote significant resourcesto create, support and maintain these services. Devices providing access to our products and services are not manufactured and sold by us, and we cannotassure you that companies manufacturing or selling these devices would always ensure that their devices perform reliably and are maximally compatible withour systems. Any faulty connection between these devices and our products may result in user dissatisfaction with our products, which could damage ourbrand and have a material and adverse effect on our financial results. In addition, the lower resolution, functionality and memory associated with somemobile devices may make the use of our products and services through such devices more difficult and the versions of our products and services we developfor these devices may fail to attract users. Manufacturers or distributors may establish unique technical standards for their devices and, as a result, ourproducts may not work or work properly or be viewable on all devices on which they are installed. Furthermore, new, comparable products which arespecifically created to function on mobile operating systems, as compared to some of our products that were originally designed to be accessed from PCs, andsuch new entrants may operate more effectively on mobile devices than our mobile products do. In addition, if we are unable to attract and retain the increasing number of users who access our products through mobile devices, or if we are slowerthan our competitors in developing attractive services adaptable for mobile devices, we may fail to capture a significant share of an increasingly importantportion of the market or may lose existing users. In addition, even if we are able to retain the increasing number of users who access our services throughmobile devices, we may not be able to successfully monetize them in the future. For example, because of the inherent limitations of mobile devices, we maynot be able to provide as many kinds of products on mobile devices as we do on PC, which may limit the monetization potential of our mobile products andservices. 9 If we fail to keep up with the technological development in the internet industry and users’ changing demand, our business, financial condition and resultsof operations may be materially and adversely affected. The internet industry is rapidly evolving and subject to continual technological changes. As the internet infrastructure continues to develop, theinternet may become more easily accessible through alternative technological innovations in the future, which may make our existing products and servicesless attractive to our users, and we may lose our existing users and fail to attract new users, which may further adversely impact our business, financialcondition and results of operations. In addition, user demand for internet content may also shift over time. Currently, internet users appear to have significant demand for multimediaacceleration, online games and online streaming services, and we expect such demand to continue. However, we cannot assure you that the behavior ofinternet users will not change in the future. If we fail to upgrade our services in response to changes in user demand in an effective and timely manner, thenumber of our users and advertisers may decrease. Furthermore, changes in technologies and user demand may require substantial capital expenditures inproduct development and infrastructure. To further expand our user base and offer our users a wider range of access points, we are expanding our business tomobile devices in part through potentially pre-installed acceleration products in mobile phones. In addition, we are continually developing and upgradingproducts and services, including our cloud computing services, which is expected to utilize the idle capacity of our users, and seeking strategic cooperationwith hardware manufacturers such as smartphone makers, which may require significant resources from us. However, if we are not able to perfect our newtechnologies or to achieve the intended results or if our innovations cannot respond to the needs of our users or if our users are not attracted to our upgradedor new products and services, we may not be able to maintain or expand our user base, and our business, results of operations and prospects may be materiallyand adversely affected. Our technologies, business methods and services, including those relating to our resource discovery network, may be subject to third-party patent claims orrights, such as issued patents or pending patent applications, that limit or prevent their use. We cannot assure you that our technologies, business methods and services, including those relating to our resource discovery network, will be freefrom claims of patent infringements, and that holders of patents would not seek to enforce such patents against us in China, the United States or any otherjurisdictions. We are currently involved in a patent infringement case in China. We believe that we did not infringe the plaintiff’s patent and we are verylikely to win the case. As of the date of this annual report, we are still waiting for the court’s decision. Other than the case mentioned above, based on our ownanalysis, we do not believe that we are currently infringing any third-party patents of which we are aware. However, our analysis may have failed to identifyall relevant patents and patent applications. For example, there may be currently pending applications, unknown to us, that may later result in issued patentsthat are infringed by our products, services or other aspects of our business. There could also be existing patents of which we are not aware that our productsmay inadvertently infringe. Third parties may attempt to enforce such patents against us. Further, the application and interpretation of China’s patent lawsand the procedures and standards for granting patents in China are still evolving and are uncertain, and we cannot assure you that PRC courts or regulatoryauthorities would agree with our analysis. Any patent infringement claims, regardless of their merits, could be time-consuming and costly to us. If we werefound to infringe third-party patents and were not able to adopt non-infringing technologies, we may be severely limited in our ability to operate ourbusiness, and our results of operations could be materially and adversely affected. The intellectual property protection mechanism we have implemented may not be effective or sufficient and may subject us to future litigation or result inour inability to continue providing certain of our existing services in China. We may not have obtained licenses for all digital media content available via our services and the scope of the licenses we obtained for certaincontent may not be broad enough to cover all the methods we currently employ to distribute, market or display such content. For digital media content wehave lawfully obtained from an authorized licensor, we may not be able to timely detect the expiration of the licensing period of certain of the contentavailable via our services and disable access to such content via our services in a timely manner. We have been involved in litigations based on allegationsfrom rights owners that we have infringed their copyright interests in such content. Assisted by our intellectual property team dedicated to copyrightprotection, for example, we have implemented internal procedures to meet the requirements under relevant PRC laws and regulations to monitor and reviewthe content we license before it is released and remove any infringing content promptly after we receive notice of infringement from the legitimate rightsholder. See also “Item 4. Information on the Company—B. Business Overview—Intellectual Property—Digital media data monitoring and copyrightprotection” for more details. However, due to the significant amount of digital media content accessible through our resource discovery network and otherservices, we generally do not seek to identify infringing content absent receiving any notice of infringement. We have successfully completed our sale ofXunlei Kankan to a third party buyer in July 2015. As a result, our exposure to claims in relation to intellectual property has significantly decreased, and wehave been adjusting our monitoring procedures in relation to intellectual property and we expect to devote more resources to the monitoring of contentaccessible via our core services. For details of our sale of Xunlei Kankan, see “Item 4. Information on the Company — A. History and Development of theCompany.” 10 In addition, we organize and recommend to our users digital media content accessible through our services and provided on certain reputable audio-visual websites that have cooperation relationships with us. As such, we may be exposed to the risk of copyright infringement liability in the event that suchcontent has not been duly licensed to us or to the operators of those websites. Moreover, some rights owners may not send us a notice before bringinglawsuits against us. Thus, our inability to identify unauthorized content hosted on our website or servers or accessible through our network subjects us toclaims of infringement of third-party intellectual property rights or other rights. In addition, we may be subject to administrative actions brought by theNational Copyright Administration of the PRC or its local branches for alleged copyright infringement. The validity, enforceability and scope of protection of intellectual property in internet-related industries, particularly in China, are uncertain andstill evolving. As we face increasing competition and as litigation becomes more common in China in resolving commercial disputes, we face a higher risk ofintellectual property infringement claims. The Supreme People’s Court of China promulgated a judicial interpretation on infringement of the right of internetdissemination in December 2012. This judicial interpretation provides that the courts will require service providers to remove not only links or content thathave been specifically mentioned in the notices of infringement from rights holders, but also links or content they “should have known” to containinfringing content. The interpretation further provides that where an internet service provider has directly obtained economic benefits from any content madeavailable by an internet user, it has a higher duty of care with respect to internet users’ infringement of third-party copyrights. This interpretation may subjectus and other internet service providers to significant administrative burdens and litigation risks. See “Item 4. Key Information on the Company—B. BusinessOverview—Regulation—Regulation on Intellectual Property Rights.” Interested parties may lobby for more robust intellectual property protection injurisdictions in which we conduct business or may conduct business, and intellectual property laws in China and other such jurisdictions may become lessfavorable to our business. Intellectual property litigation may be expensive and time-consuming and could divert management attention and resources. Ifthere is a successful claim of infringement, we may be required to discontinue the infringing activities, pay substantial fines and damages and/or seek royaltyor license agreements that may not be available on commercially acceptable terms, if at all. Our failure to obtain the required licenses on a timely basis couldharm our business. Any intellectual property litigation and/or any negative publicity by third parties alleging our intellectual property infringement couldhave a material adverse effect on our business, reputation, financial condition or results of operations. To address the risks relating to intellectual propertyinfringement, we may have to substantially modify, limit or, in extreme cases, terminate some of our services. Any of such changes could materially affect ourusers’ experience and in turn have a material adverse impact on our business. We may be subject to claims or lawsuits outside of China, which could increase our risk of direct or indirect liabilities for our existing or future serviceofferings. We may be subject to claims or lawsuits outside China, such as the United States, by virtue of our listing in the United States, the ownership of ourADSs by investors, the extraterritorial application of foreign law by foreign courts or for other reasons. We have attracted and expect to continue to attractattention from intellectual property owners outside of China, despite our efforts to control access to our products and services by users outside China. Forexample, the Recording Industry Association of America filed a letter with the Office of the United States Trade Representative in November 2010 accusingcertain of our divested or discontinued products of facilitating intellectual property infringement. Although we take steps to block users logging in from IPaddresses that are located in certain jurisdictions, including the United States, from accessing certain of our services, due to technological limitations, suchefforts may not be 100% successful, and any unintended access to our services may increase our risk of becoming subject to copyright laws in suchjurisdictions. Even if our efforts to block IP addresses located in the United States or other jurisdictions are successful, the uncertainties surrounding theapproach to intellectual property and online service providers that the new U.S. administration will take may increase our risk of becoming impacted bycopyright laws in such jurisdictions. If we are ever held to be subject to United States copyright law, that could increase our risk of direct or indirectcopyright liability for our resource discovery, acceleration or other services. If a claim of infringement brought against us in the United States or otherjurisdictions is successful, we may be required to (i) pay substantial statutory or other damages and fines, (ii) remove relevant content from our website, (iii)discontinue products or services, (iv) disable access through our service to certain sites or content; (v) terminate users; and/or (vi) seek royalty or licenseagreements that may not be available on commercially reasonable terms or at all. 11 In addition, as a publicly listed company, we may be exposed to increased risk of litigation. For example, two putative shareholder class actionlawsuits have been filed in the United States District Courts for the Southern District of New York against our Company and certain current and formerofficers and directors of our Company: Dookeran v. Xunlei Limited, et al. (filed on January 18, 2018, Case No. 18-cv-467 (S.D.N.Y.)), and Peng Li v. XunleiLimited, et al. (filed on January 24, 2018, Case No. 18-cv-646 (S.D.N.Y.)). Purporting to sue on behalf of all investors who purchased or acquired Xunlei stockfrom October 10, 2017, to January 11, 2018, plaintiffs allege that certain statements regarding OneCoin, in our press releases and on a quarterly investor callwere false and misleading because, among other things, they failed to disclose that OneCoin was a disguised “initial coin offering” and “initial mineroffering” and constituted “unlawful financial activity.” Plaintiffs seek to recover under Sections 10(b) and 20(a) of the U.S. Securities Exchange Act of 1934and 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 and lead plaintiffs’ counsel. The proceedings are still at an early stage, and the consolidated amended complaint has notyet been filed. As a publicly listed company, we may be involved in more class action lawsuits in the future. While we believe the claims in this lawsuit arewithout merit, such kind of lawsuit could divert a significant amount of our management’s attention and other resources from our business and operations,which could harm our results of operations and require us to incur significant expenses to defend the lawsuits. Any such class action suit, whether or notsuccessful, could harm our reputation and restrict our ability to raise capital in the future. In addition, if a claim is successfully made against us, we may berequired to pay significant damages, which could have a material adverse effect on our financial condition and results of operations. We may not be able to prevent unauthorized use of our intellectual property or disclosure of our trade secrets and other proprietary information, whichcould reduce demand for our services and have material and adverse impact on our business, financial condition and results of operations. Our patents, trademarks, trade secrets, copyrights and other intellectual property rights are important assets for us. Events that are outside of ourcontrol may pose a threat to our intellectual property rights. For example, effective intellectual property protection may not be available in China and someother jurisdictions in which our services are distributed or made available through the internet. Also, the efforts we have made to protect our proprietary rightsmay not be sufficient or effective. Any significant impairment of our intellectual property rights could harm our business or our competitiveness. Also,protecting our intellectual property rights is costly and time consuming. Any increase in the unauthorized use of our intellectual property could make it moreexpensive to conduct our business and harm our results of operations. We seek to obtain patent protection for our innovations. However, it is possible that patent protection may not be available for some of theseinnovations. In addition, given the costs of obtaining patent protection, we may choose not to protect certain innovations that later turn out to be important.Furthermore, there is always the possibility, despite our efforts, that the scope of the protection gained will be insufficient or that an issued patent may bedeemed invalid or unenforceable. We also seek to maintain certain intellectual property as trade secrets. We require our employees, consultants, advisors and collaborators to enterinto confidentiality agreements in order to protect our trade secrets and other proprietary information. These agreements might not effectively preventdisclosure of our trade secrets, know-how or other proprietary information and might not provide an adequate remedy in the event of unauthorized disclosureof such confidential information. In addition, others may independently discover our trade secrets and proprietary information, in which case we could notassert such trade secret rights against such parties. Any unauthorized disclosure or independent discovery of our trade secrets would deprive us of theassociated competitive advantages. Costly and time-consuming litigation could be necessary to enforce and determine the scope of our proprietary rights,and failure to obtain or maintain trade secret protection could adversely affect our competitive position. 12 The revenue model for our live video may not remain effective and we cannot guarantee that our future monetization strategies will be successfullyimplemented or generate sustainable revenues and profit. We launched our live video services in February 2016. In 2017, we adjusted our live video business and adopted a revenue model whereby usershave free access to live video of various types of content presented by broadcasters but have the options to purchase virtual items. In 2017, revenues fromlive video services was US$18.0 million, which accounted for 8.9% of our total net revenues in 2017. Almost all of our live video revenue was generatedusing this revenue model and we expect to continue to generate our live video revenue using this revenue model. Our live video business has experiencedrapid growth after its launch, but we cannot assure you that we will be able to continue to achieve a similar or higher growth rate in the future, as the userdemand for this service may change, decrease substantially or dissipate, or we may fail to anticipate and serve user demands effectively. Although we factor in industry standards and expected user demand in determining how to optimize virtual item merchandizing effectively, if wefail to properly manage the supply and timing of our virtual items and their appropriate prices, our users may be less likely to purchase these virtual itemsfrom us. In addition, if users’ spending habits change and they choose to only access our content for free without additional purchases, we may not be able tocontinue to successfully implement the virtual items-based revenue model for live video, in which case we may have to provide other value-added services orproducts to monetize our user base. We cannot guarantee that our attempts to monetize our user base and products and services will continue to be successful,profitable or widely accepted, and therefore the future revenue and income potential of our business are difficult to evaluate. We may fail to offer attractive content for our live video services, or attract and retain talented and popular broadcasters, which may materially adverselyaffect the operation of our live video services and its results of operations. We offer comprehensive live video content. Our content library is constantly evolving and growing to meet users’ evolving interests. We activelytrack viewership growth and community feedback to identify trending content and encourage our broadcasters to create content that caters to users’constantly changing taste. However, if we fail to continue to expand and diversify our content offerings, identify trending and popular genres, or maintain thequality of our content, we may experience decreased viewership and user engagement, which may materially and adversely affect our results of operationsand financial conditions. In addition, we largely rely on our broadcasters to create high-quality and fun live video content. Popular broadcasters are key to the success of ourliving streaming services. We have in place a comprehensive and effective incentive mechanism to encourage broadcasters to supply content that areattractive to our users. We have also entered into multi-year cooperation agreements that contain exclusivity clauses with popular broadcasters and the talentagencies they cooperate with. However, if any of those broadcasters and/or the talent agencies decides to breach the agreement or chooses not to continue thecooperation with us once the term of the agreement expires, or if we fail to attract new talented and productive broadcasters, the popularity of our platformmay decline and the number of our users may decrease, which could materially and adversely affect our results of operations and financial condition. We may be held liable for information or content displayed on, retrieved from or linked to our platforms, or distributed to our users, and PRC authoritiesmay impose legal sanctions on us, including, in serious cases, suspending or revoking the licenses necessary to operate our platforms. Our live video services enable users to exchange information and engage in various other online activities. Although we require our broadcasters toregister their real name, we do not require real-name registration for our users, and hence we are unable to verify the sources of all the information posted byour users. In addition, a majority of the communications on our platforms is conducted real-time, we are unable to timely verify the sources of all informationposted thereon or examine the content generated by users before they are posted. Therefore, it is possible that broadcasters and/or users may engage in illegal,obscene or incendiary conversations or activities, including the publishing of inappropriate or illegal content that may be deemed unlawful under PRC lawsand regulations on our platforms. If any content on our platforms is deemed illegal, obscene or incendiary, or if appropriate licenses and third party consentshave not been obtained, claims may be brought against us for defamation, libel, negligence, copyright, patent or trademark infringement, other unlawfulactivities or other theories and claims based on the nature and content of the information delivered on or otherwise accessed through our platforms. We alsomay face liability for copyright or trademark infringement, fraud, and other claims based on the nature and content of the materials that are delivered, sharedor otherwise accessed through or published on our platforms. Defending any such actions could be costly and involve significant time and attention of ourmanagement and other resources. In addition, PRC authorities may impose legal sanctions on us, including, in serious cases, suspending or revoking thelicenses necessary to operate our platforms if they find that we have not adequately managed the content on our platforms. The success of our businessdepends on our ability to maintain and enhance a strong brand. If we fail to sustain or improve the strength of our brand, we may subsequently experiencedifficulty in maintaining market share. 13 We believe that maintaining and enhancing our Xunlei brand is of significant importance to the success of our business. A well-recognized brand iscritical to increasing our user base and, in turn, enhancing our attractiveness to advertisers, subscribers and paying users. Since the Chinese internet market ishighly competitive, maintaining and enhancing our brand depends largely on our ability to retain a significant market share in China, which may be difficultand expensive. We have developed our reputation and established a leading position by providing our users with a superior acceleration and video viewingexperience. We will continue to conduct various marketing and brand promotion activities. We cannot assure you, however, that these activities will besuccessful and achieve the brand promotion effects we expect. In addition, any negative publicity in relation to our services or our marketing or promotionpractices, regardless of its veracity, could harm our brand image and, in turn, result in a reduced number of users and advertisers. Historically, there has beennegative publicity about our company, our products and services and certain key members of our management team, which has adversely affected our brand,public image and reputation. If we fail to maintain and enhance our brand, or if we incur excessive expenses in this effort, our business, financial conditionand results of operations may be materially and adversely affected. System failure, interruptions and downtime, including those caused by cyber-attacks or network issues, can result in user dissatisfaction and adversepublicity, and our business, financial condition and results of operations may be materially and adversely affected. Our operations rely on our networks and servers, which can suffer system failures, interruptions and downtime. Our network systems are vulnerable todamage from computer viruses, fires, floods, earthquakes, power losses, telecommunication failures, computer hacking and similar events despite ourimplementation of security measures, which may cause interruptions to the services we provide, degrade the user experience, or cause users to lose confidencein our products. Our efforts to protect our company data or the information we receive may also be unsuccessful due to software bugs or other technicalmalfunctions, employee error or malfeasance, government surveillance, or other factors. The satisfactory performance, stability, security and availability of our websites and our network infrastructure are critical to our reputation and ourability to attract and retain users and advertisers. Our network contains information regarding file index, advertising records, premium licensed digital mediacontent and various other facets of the business to assist management and help ensure effective communication among various departments and offices of ourcompany. Any failure to maintain the satisfactory performance, stability, security and availability of our network, website or technology platform, whethersuch failure results from intentional cyber-attacks by hackers, from issues with our own technology and team or from other factors beyond our control, maycause significant harm to our reputation and impact our ability to attract and maintain users and business partners. We have put in place various measures toprevent such incidents from happening and internal reporting procedures with respect to such incidents. However, such prevention measures may notfunction in a way as we expect. From time to time, our users in certain locations may not be able to gain access to our network or our websites for a period of time lasting fromseveral minutes to several hours, due to server interruptions, power shutdowns, internet connection problems or other reasons. Although we have notexperienced extended periods of such server interruptions, power shutdowns or internet connection problems across our entire network, we cannot assure youthat such instances will not occur in the future. Any server interruptions, break-downs or system failures, including failures which may be attributable toevents within or outside our control that could result in a sustained shutdown of all or a material portion of our network or website, could reduce theattractiveness of our service offerings. In addition, any substantial increase in the volume of traffic on our network or website will require us to increase ourinvestment in bandwidth, expand and further upgrade our technology platform. We do not maintain insurance policies covering losses relating to ournetwork systems. As a result, any system failure, interruptions or network downtime for an extended period may have a material adverse impact on ourrevenues and results of operations. 14 If we fail to retain existing advertisers or attract new advertisers, our revenues may be materially and adversely affected. Historically, we generate a substantial portion of our revenues from online advertising. Such revenue experienced a decline from US$38.4 million in2014 to US$4.8 million in 2015 due to our disposal of Xunlei Kankan in July 2015, which historically contributed a significant portion of our advertisingrevenues and a majority of our advertisers. The revenue from online advertising, however, increased to US$16.9 million in 2016 due to the rapid growth ofour mobile advertising since the fourth quarter of 2015. In 2017, the revenue from our online advertising further increased to US$22.5 million due to a higherfee we charged to advertisers for each advertisement placed on our products and platforms. We cannot assure you that we can continue to retain ouradvertising agencies and advertisers or attract new advertising agencies and advertisers. The number of advertisers (including third party advertisingplatforms that we cooperate with) that use our online advertising services decreased from 252 in 2014 to 120 in 2015 due to the disposal of Xunlei Kankan inJuly 2015, and such number further decreased to 112 in 2017. If we cannot retain our existing advertisers or develop new advertisers in the future, ourrevenues generated from online advertising will be materially and negatively affected. Since our arrangements with third-party advertising agencies aretypically one-year framework agreements, such advertising arrangements may be easily amended or terminated without incurring liabilities. A number of our advertisers are online game operators. The online game and e-commerce industries in China are rapidly evolving, and the growth ofthese industries and their demand for online advertising services is uncertain and may be affected by factors out of our control. We also have significantbrand advertising and are seeking to further expand this portion of advertising. However, we cannot assure you that we will be able to retain existingadvertising agencies and advertisers or attract more advertising agencies and advertisers for brand advertising, and if we fail to do so, our business, results ofoperations and prospects may be materially and adversely affected. We rely on third-party platforms to distribute our mobile applications. If we are unable to maintain a good relationship with such platform providers, iftheir terms and conditions or pricing were changed to our detriment, if we violate, or if a platform provider believes that we have violated, the terms andconditions of its platform, or if any of these platforms loses market share or falls out of favor or is unavailable for a prolonged period of time, our mobilestrategy may suffer. We are subject to the standard policies and terms of service of third party platforms, which govern the distribution of our mobile application on theplatform. Each platform provider has broad discretion to change and interpret its terms of service and other policies with respect to us and other users, andthose changes may be unfavorable to us. A platform provider may also change its fee structure, add fees associated with access to and use of its platform, alterhow we are able to advertise or distribute on the platform, or change how the personal information of its users is made available to application developers onthe platform. Such changes may decrease the visibility or availability of our applications, limit our distribution capabilities, prevent access to ourapplications, reduce the amount of downloads and revenue we may recognize from the applications, increase our costs to operate on these platforms or resultin the exclusion or limitation of our application on such platforms. Any such changes could adversely affect our business, financial condition or results ofoperations. If we violate, or a platform provider believes we have violated its terms of service (or if there is any change or deterioration in our relationship withthese platform providers), that platform provider could limit or discontinue our access to the platform. A platform provider could also limit or discontinueour access to the platform if it establishes more favorable relationships with one or more of our competitors or it determines that we are a competitor. Anylimit of, or discontinuation to, our access to any platform could adversely affect our business, financial condition or results of operations. In September 2016,Mobile Xunlei was removed from Apple’s iOS App Store as a result of alleged possible violations of the developer license agreement between Apple and us.We are still in the process of negotiating with Apple. We cannot assure you that future efforts to re-launch Mobile Xunlei on the iOS App Store will besuccessful. This will most likely prevent prospective users and existing users from accessing or renewing our services through Apple devices. It is impossiblefor us to predict the impact in the longer run if Apple continues to deny our mobile applications. Furthermore, other app stores also have the right to updatetheir store policies and if we are deemed to violate its policy and our mobile application are removed from other app stores at the same time, this maysignificantly harm our mobile strategy. 15 We are strictly regulated in China. Any lack of requisite licenses or permits applicable to our businesses and any changes in government policies orregulations may have a material and adverse impact on our businesses, financial conditions and results of operations. Our business is subject to governmental supervision and regulations by the relevant PRC governmental authorities including the State Council, theMinistry of Industry and Information Technology (formerly the Ministry of Information Industry), or MIIT, the State Administration of Radio and Television,or SAPPRFT, (formerly the General Administration of Press and Publication, Radio, Film and Television (established in March 2013 as a result ofinstitutional reform integrating the State Administration of Radio, Film and Television, and the General Administration of Press and Publication), orGAPPRFT), Ministry of Culture and Tourism (established in March 2018 as a result of institutional reform integrating the Ministry of Culture, and theMinistry of Tourism), or MOCT and other relevant government authorities. Together these government authorities promulgate and enforce regulations thatcover many aspects of operation of telecommunications and internet information services, including entry into the telecommunications industry, the scope ofpermissible business activities, licenses and permits for various business activities and foreign investment. We are advised by our PRC legal adviser that a license for online transmission of audio-visual programs is required for the display of video content,including live video content, on our platform. See “Item 4. Information on the Company—B. Business Overview—Regulation—Regulation on onlinetransmission of audio-visual programs.” We used to be a registered owner of such license when we were operating Xunlei Kankan business. However, whenwe disposed of Xunlei Kankan business to the purchaser in July 2015, the registered owner of such license was also changed to the purchaser. Our platformand software gather internet audio-video programs and contains user generated live video content, video clips and other media files. Our platform also offersonline shows, online games and online drama performances. The broadcasters may also upload their recorded video clips to our platform. The live videoindustry is relatively new in China. Laws and regulations governing the operation of live video services are also developing and evolving. Substantialuncertainties exist with respect to the interpretation and implementation of the applicable laws and regulations. Relevant PRC government authorities mayfind that the license for online transmission of audio-visual programs is also required for our gathering and transmission of live video content, video clips andmedia files. If the relevant PRC authorities consider that we are operating relevant businesses without proper license, they may issue warnings, order us torectify our violating operations and impose fines on us. In case of severe contravention as determined by relevant authorities in its discretion, they may banthe violating operations, seize our equipment in connection with such operations and impose a penalty of one to two times of the amount of the totalinvestment in such operations. We are now in the process of obtaining a new license for online transmission of audio-visual programs and expect to obtainsuch license in late 2018. In addition, our cloud computing services provided to the internet users may be deemed to have included the content distribution network (CDN)services. With MIIT’s recent promulgation of the Circular on Clearing up and Regulating the Internet Access Service Market in January 2017, our existingvalue-added telecommunication services license, or VATS License, must be updated to specifically cover the CDN services, which otherwise was not requiredin the past. Shenzhen Onething Technologies Co., Ltd., or Shenzhen Onething, a subsidiary of Shenzhen Xunlei has obtained from the relevant PRCauthority an updated VATS License covering the CDN services. “Item 4. Information on the Company—B. Business Overview—Regulation—Regulation ontelecommunications and internet information services.” If the relevant PRC authority decides that we were operating without the proper licenses or approvals, we may be given a warning, ordered to rectifyour violations and/or fined, or required to impose restrictions or even discontinue our relevant business. In addition to the above, if the PRC governmentpromulgates new laws and regulations that require additional licenses or imposes additional restrictions on the operation of any part of our business, it hasthe power to, among other things, levy fines, confiscate our income, revoke our business licenses, and require us to discontinue our business or imposerestrictions on the affected portion of our business. Any of these actions by the PRC government may have a material and adverse effect on our results ofoperations. In addition, the PRC government may promulgate regulations restricting the types and content of advertisements that may be transmitted online,which could have a direct adverse impact on our business. 16 Concerns about collection and use of personal data could damage our reputation, deter current and potential users from using our services andsubstantially harm our business and results of operations. Pursuant to the applicable PRC laws and regulations concerning the collection, use and sharing of personal data, our PRC subsidiaries, VIE and itssubsidiaries are required to keep our users’ personal information confidential and are prohibited from disclosing such information to any third parties withoutsuch users’ consent. In December 2012 and July 2013, laws and regulations were issued by the Standing Committee of the PRC National People’s Congressand MIIT to enhance the legal protection of information security and privacy on the internet. The laws and regulations also require internet operators to takemeasures to ensure confidentiality of information of users. Concerns about our practices with regard to the collection, use or disclosure of personalinformation or other privacy-related matters, even if unfounded, could damage our reputation and operating results. In addition, in June 2016 and January2017, the Cyberspace Administration of China, or CAC, and the Standing Committee of the PRC National People’s Congress issued new laws and regulationsto further safeguard cyberspace security. We apply strict management and protection to any information provided by users, and under our privacy policy, without our users’ prior consent, wewill not provide any of our users’ personal information to any unrelated third party. While we strive to comply with our privacy guidelines as well as allapplicable data protection laws and regulations, any failure or perceived failure to comply may result in proceedings or actions against us by governmententities or others, and could damage our reputation. User and regulatory attitudes towards privacy are evolving and concerns about the security of personaldata could also lead to a decline in general usage of our products and services, which could lead to lower user numbers. For example, if the PRC governmentauthorities require real-name registration by our users, our user numbers may decrease and our business, financial condition and results of operations may beadversely affected. See “—Risks Related to Doing Business in China—We may be adversely affected by the complexity, uncertainties and changes in PRCregulations of internet-related business and companies.” In addition, we may become subject to the data protection or personal privacy laws of jurisdictionsoutside of China, where more stringent requirements may be imposed on us and we may have to allocate more resources to comply with the legalrequirements, and our user numbers may further decrease. A significant reduction in user numbers could have a material adverse effect on our business,financial condition and results of operations. We may not be able to generate sufficient cash from operations or to obtain sufficient capital to meet the additional capital requirements of our changingbusiness. In order to implement our development strategies, including our strategies to transition to mobile internet and continuing efforts on our cloudcomputing business, we will make continual capital investments in terms of devoting more research and development efforts into investigating user needsand develop new mobile products and update existing ones, continue enhancing the technologies involved in our cloud computing business and providemore frequent updates to our existing products. Thus, we will continue to incur substantial capital expenditures on an ongoing basis, and it may becomedifficult for us to meet such capital requirements. To date, we have financed our operations primarily through cash flow from operations and, to a lesser degree, proceeds from private placements ofpreferred shares and our initial public offering. If we fail to retain a sufficient number of users and continue to convert such users into paying users orsubscribers, we may not be able to generate sufficient revenues to cover our business development strategies, including our continued transition to mobileinternet and the continued expansion of our cloud computing business, and our business may be materially and adversely affected. We may obtain additional financing, including from equity offerings and debt financings in capital markets, to fund the operation and plannedexpansion of our business. Our ability to obtain additional financing in the future, however, is subject to a number of uncertainties, including: ·our future business development, financial condition and results of operations; ·general market conditions for financing activities by companies in our industry; and ·macroeconomic, political and other conditions in China and elsewhere. If we cannot obtain sufficient capital to meet our capital expenditure needs, we may not be able to execute our growth strategies and our business,results of operations and prospects may be materially and adversely affected. 17 Our costs and expenses, such as research and development expenses, may increase and our results of operations may be adversely affected. The operation of our extensive resource discovery network and cloud computing business require significant upfront capital expenditures as well ascontinual, substantial investment in content, technology and infrastructure. Since inception, we have invested substantially in research and development tomaintain our technology leadership, and in equipment to increase our network capacity. We expect our research and development expenses to increase in thenear term as we continue to expand our research and development team to develop new products and update existing products, particularly as we continuedevoting resources in the development of our cloud computing business and the development and updating of our mobile products. Most of our capitalexpenditures, such as expenditures on servers and other equipment, are based upon our estimation of potential future demand and we are generally requiredto pay the entire purchase price and license fees upfront. As a result, our cash flow may be negatively affected in the periods in which such payments aremade. We may not be able to quickly generate sufficient revenue from such expenditures, which may negatively affect our results of operations within certainperiods thereafter; and if we over-estimate future demand for our services, we may not be able to achieve expected rates of return on our capital expenditures,or at all. In addition, bandwidth and other costs are subject to change and are determined by market supply and demand. For example, the market prices forprofessionally produced digital media content have increased significantly in China during the past few years, and there have been increases in the relevantlicense fees. In addition, if bandwidth and other providers cease their business with us or raise the prices of their products and services, we will incuradditional costs to find alternative service providers or to accept the increased costs in order to provide our services, although we expect that crowdsourcedcapacity obtained through our cloud computing services may offset some of our bandwidth costs. If we cannot pass on our costs and expenses to our users, orif our costs to deliver our services do not decline commensurate with any future declines in the prices we charge our users, our results of operations may beadversely affected and we may fail to achieve profitability. If we are unable to collect accounts receivable in a timely manner or at all, our financial condition, results of operations and prospects may be materiallyand adversely affected. Certain portion of our advertising revenues is generated from a limited number of advertising agencies. We typically enter into advertisingagreements with third-party advertising agencies that represent the advertisers, and under these agreements, the advertising fees are paid to us by theadvertising agencies after we deliver our services. In consideration for the third-party advertising agencies’ services, we pay them rebates based on the valueof business they bring to us. In addition to our online advertising services, we also generated a large portion of our revenue from the sales of CDN to ourcustomers in 2017. As of December 31, 2017, we have a considerable portion of accounts receivable arising from the sales of CDN. Thus, the financialsoundness of our advertisers and advertising agencies, as well as our customers purchasing CDN from us may affect our collection of accounts receivable. Wemake a credit assessment of our advertisers, advertising agencies and our CDN purchasers to evaluate the collectability of these service fees before enteringinto any business contracts. However, we cannot assure you that we are or will be able to accurately assess the creditworthiness of each advertising agency,advertiser or CDN purchaser, as applicable, and any inability of advertisers, advertising agencies or CDN purchasers, especially those that accounted for asignificant percentage of our amounts receivables in the past, to pay us in a timely manner may adversely affect our liquidity and cash flows. In addition, theonline advertising market in China is dominated by a small number of large advertising agencies. If the large advertising agencies that we have businessrelationships with demand higher rebates for their agency services, our results of operations will be materially and adversely affected. We may not be able to successfully address the challenges and risks we face in the online games market, such as a failure to acquire and operate popular,high-quality games or to obtain all the licenses required to operate online games, which may subject us to penalties from relevant authorities, includingthe discontinuance of our online game business. Our online game business used to consist of web game business, mobile game business, and MMOGs. In order to further develop our cloudcomputing business, we streamlined our overall business and disposed our web game business in January 2018. After the disposal, our online game businesscurrently only operates mobile games and MMOGs. We have exclusive operating agreements with online game developers, under which we gain exclusiverights to certain online games. In addition to offering these games on our own websites, we also have the option of sub-licensing these games to otherwebsites to diversify our game revenue stream. Exclusive arrangements of this type require more initial capital investment in acquiring operating rights forthe games, and involve more business risks, such as risks associated with the potential failure to find appropriate sub-licensees for the games or failure toengage a sufficient number of game players to make these games profitable for us. If we are unable to generate sufficient revenues in these markets to obtainsufficient return for our investments, our future results of operations and financial condition could be materially and adversely affected. 18 In addition, to operate online games in China, a variety of permits and approvals are required. For example, publication of online games, musicworks and other internet publishing activities are subject to the regulation of the SAPPRFT, which requires operators of online games and other internetpublishing services to obtain an internet publication license prior to providing any such services. See “Item 4. Information on the Company—B. BusinessOverview—Regulation—Regulation on internet publication.” Shenzhen Xunlei has obtained an internet publication license for the publication of internetgames. However, Shenzhen Xunlei’s internet publication license does not include the publication of music works and other internet publishing activities.Applicable regulations also specify that each online game must be screened and approved in advance by SAPPRFT before it is allowed to be launchedonline. Also, an imported online game should be approved in advance by MOCT before its initial operation while a domestically developed online gameshould be filed with MOCT within 30 days of commencing operations. See “Item 4. Information on the Company—B. Business Overview—Regulation—Regulation on online games.” We license from online game developers and operate massive multiplayer online games, or the MMOGs, and we share profitswith these developers. We require developers of certain online games to obtain the requisite approvals from SAPPRFT, and make the filings with MOCT, forrelevant online games. As of the date of this annual report, most of our online games currently in operation exclusively by us have obtained SAPPRFT’sapproval and completed filing with MOCT. However, we cannot assure you that we or such online game developers can obtain SAPPRFT’s approvals orcomplete the filings with MOCT for all the games in a timely manner or at all. If we or such online game developers fail to obtain these licenses, approvals orfilings in a timely manner or at all, the relevant authority may challenge the commercial operation of our online games and determine that we are in violationof the relevant laws and regulations regarding online games, it would have the power to, among other things, levy fines against us, confiscate our incomegenerated from operation of our online games and require us to discontinue our online game business. We operate in a competitive market and may not be able to compete effectively. We face significant competition in different areas of our business. For example, although we currently have a leading presence in the China marketfor cloud acceleration products and services, we cannot guarantee that we will be able to maintain our leading position in the future. We may facecompetition from leading Chinese internet companies, such as Tencent and Baidu, if they start to allocate resources and focus on the development in thisbusiness sector. With more entrants into the cloud acceleration business, aggressive price cutting by competitors may result in the loss of our existingsubscribers. We may have to take actions to retain our user base and attract more subscribers at significant cost, including upgrading and developing existingand new products and services in order to meet users’ changing demand, but we cannot assure you that such efforts will succeed, especially given thetightening control over internet content by the Chinese government. See “—If we fail to keep up with the technological development in the internet industryand users’ changing demand, our business, financial condition and results of operations may be materially and adversely affected.” and “—Regulation andcensorship of information disseminated over the internet in China have adversely affected our business and may continue to adversely affect our business,and we may be liable for the digital media content on our platform.” Some of our existing or potential competitors have a longer operating history and significantly greater financial resources than we do, and in turnmay be able to attract and retain more users and advertisers. Our competitors may compete with us in a variety of ways, including by conducting brandpromotions and other marketing activities and making acquisitions. If we are not able to effectively compete in any aspect of our business, which would havea material and adverse effect on our business, financial condition and results of operations. 19 Undetected programming errors or flaws or failure to maintain effective customer service could harm our reputation or decrease market acceptance of ourservices, particularly our resource discovery network, which would materially and adversely affect our results of operations. Our programs may contain programming errors that may only become apparent after their release, especially in terms of upgrades to, for example,Xunlei Accelerator or cloud acceleration subscription services. We receive user feedback in connection with programming errors affecting their userexperience from time to time, and such errors may also come to our attention during our monitoring process. However, we cannot assure you that we will beable to detect and resolve all these programming errors effectively or in a timely manner. Undetected programming errors or defects may adversely affect userexperience and cause our users to stop using our services and our advertisers to reduce their use of our services, any of which could materially and adverselyaffect our business and results of operations. Advertisements we display may subject us to penalties and other administrative actions. Under PRC advertising laws and regulations, advertisement channels such as us are obligated to monitor the advertising content they display toensure that such content is true, accurate and in full compliance with applicable laws and regulations. PRC advertising laws and regulations set forth certaincontent requirements for advertisements in the PRC including, among other things, prohibitions on false or misleading content, superlative wording, sociallydestabilizing content or content involving obscenities, superstition, violence, discrimination or infringement of the public interest. In April 2015, theStanding Committee of the National People’s Congress issued the amended Advertisement Law, which took effect on September 1, 2015, to furtherstrengthen the supervision and management of advertisement services. Pursuant to the Advertisement Law, any advertisement that contains false ormisleading information to deceive or mislead consumers shall be deemed false advertising. Furthermore, the Advertisement Law explicitly stipulates detailedrequirements for the content of several different kinds of advertisement, including advertisements for medical treatment, pharmaceuticals, medicalinstruments, health food, alcoholic drinks, education or training, products or services having an expected return on investment, real estate, pesticides, feedand feed additives, and some other agriculture-related advertisement. On July 4, 2016, SAIC issued the Interim Measures for the Administration of InternetAdvertising to specifically regulate internet advertising activities. See “Item 4. Information on the Company—B. Business Overview—Regulation—Regulation on advertising business” for details. In providing advertising services, we are required to review the supporting documents provided to us byadvertising agencies or advertisers for the relevant advertisements and verify that the content of the advertisements complies with applicable PRC laws andregulations. Prior to distributing advertisements that are subject to government censorship and approval, we are obligated to verify that such censorship hasbeen performed and approval has been obtained. Violation of these regulations may result in penalties, including fines, confiscation of advertising income,orders to eliminate the effect of illegal advertisement. In circumstances involving serious violations, the State Administration for Industry and Commerce, orthe SAIC, or its local branches may revoke violators’ licenses or permits for their advertising business operations. To fulfill these monitoring functions specified by the PRC laws and regulations set forth above, we employ several measures. Almost all of ouradvertising contracts require that advertising agencies or advertisers that contract with us: (i) ensure the advertising content provided to us is true, accurateand in full compliance with PRC laws and regulations; (ii) ensure such content does not infringe any third-party’s rights and interests; and (iii) indemnify usfor any liabilities arising from such advertising content. In addition, a team of our employees reviews all advertising materials to ensure the content does notviolate relevant laws and regulations before displaying such advertisements. However, we cannot assure you that all the content contained in suchadvertisements is true and accurate as required by the advertising laws and regulations, especially given the uncertainty in the application of these laws andregulations. If we are found to be in violation of applicable PRC advertising laws and regulations in the future, we may be subject to penalties and ourreputation may be harmed, which may have a material and adverse effect on our business, financial condition and results of operations. We face risks relating to third parties’ billing and payment systems. The billing and payment systems of third parties such as online third-party payment processors help us maintain accurate records of payments ofsales proceeds by certain subscribers and other paying users and collect such payments. Our business and results of operations could be adversely affected ifthese third parties fail to accurately account for or calculate the revenues generated from the sales of our products and services. Moreover, if there are securitybreaches or failure or errors in the payment process of these third parties, user experience may be affected and our business results may be negativelyimpacted. 20 The channels for the payment of our services and products typically comprise third-party online system, fixed phone line and mobile phonepayment. A significant portion of the payments have been made through our online payment system since 2014. Although we have been able to control ourpayment handling charges by encouraging our subscribers to use the third-party online system which charges relatively lower levels of handling feescompared with other payment channels, the subscribers may change their habits to make payments through mobile phones or other distribution channels withhigher costs. If more and more subscribers use the mobile phone as their payment channels and the cost remains unchanged or even increases in the future, orif we fail to minimize the associated payment handling charges, our results of operations may be adversely affected. We also do not have control over the security measures of our third-party payment service providers, and security breaches of the online paymentsystems that we use could expose us to litigation and possible liability for failing to secure confidential customer information and could, among other things,damage our reputation and the perceived security of all of the online payment systems we use. In addition, there may be billing software errors that woulddamage customer confidence in these payment systems. If any of the above were to occur, we may lose paying users and users may be discouraged frompurchasing our products, which may have an adverse effect on our business and results of operations. Third-party e-commerce platform is a major way for us to sell our OneThing Cloud and collect payments. If we fail to maintain our relationship withthird-party e-commerce platform, the sales of our OneThing Cloud and our cloud computing business may be adversely affected. In addition to our proprietary distribution channels, we also sell our OneThing Cloud through a major third-party e-commerce platform in China andcollect payments from such platform. We are subject to its standard terms and conditions for selling product through its platform, which govern placing ofpurchase order, transportation and delivery of products, sales returns and payment settlement. If we violate, or if the platform provider believes that we haveviolated, its terms and conditions, it may discontinue or limit our access to that platform, which could harm the sales of our OneThing Cloud and our cloudcomputing business. Disputes with the third-party platform, such as disputes relating to fee arrangements and billing issues, may also arise from time to time and wecannot assure you that we will be able to resolve such disputes in a timely manner or at all. If our collaboration with the third-party platform terminates forany reason, we may not be able to find a replacement in a timely manner at terms acceptable to us or at all and the sales of our OneThing Cloud may beadversely affected. Any failure on our part to maintain good relationships with the third-party e-commerce platform, the sales of our OneThing Cloud coulddecline, which will have an adverse effect on our business, financial condition and results of operations. If the e-commerce platform, through which we sell our OneThing Cloud, loses its market position or is no longer popular with users, our ability toreach more users will be limited. In addition, we would need to identify alternative channels for marketing and selling our OneThing Cloud, which wouldconsume additional resources and may not be effective. We do not have internal manufacturing capabilities and rely on several contract manufacturers to produce our products. If we encounter issues with thesecontract manufacturers, our business, brand and results of operations could be harmed. We do not maintain our own manufacturing capabilities and rely on contract manufactures to produce our products. We assign the production ofOneThing Cloud to a number of manufacturers. We may experience operational difficulties with our manufacturers, including reductions in the availabilityof production capacity, failures to comply with product specifications, insufficient quality control, failures to meet production deadlines, increases inmanufacturing costs. Our manufacturers may experience disruptions in their manufacturing operations due to equipment breakdowns, labor strikes orshortages, natural disasters, component or material shortages, cost increases or other similar problems. In addition, we may not be able to renew contracts withour contract manufacturers or identify alternative manufacturers in a timely manner at terms acceptable to us. If any of the above were to happen, ourmanufacturing of OneThing Cloud and our cloud computing business may be adversely affected. 21 We are susceptible to supply shortages, long lead time for raw materials and components, and supply changes, any of which could disrupt our supply chainand have a material adverse impact on our results of operation because some of the key components of our products come from a limited number or asingle source of supply. All of the components and raw materials used to produce OneThing Cloud are sourced from third-party suppliers, and some of these components aresourced from a limited number of or a single supplier. Therefore, we are subject to risks of shortages or discontinuation in supply, cost increases and qualitycontrol issues with the limited sources of suppliers. We may in the future experience component shortages. In the event of a component shortage or supplyinterruption from suppliers of key components, we will need to identify alternate sources of supply, which can be time-consuming, difficult and costly. Wemay not be able to source these components on terms that are acceptable to us, or at all, which may undermine our ability to meet our productionrequirements or to fill our orders in a timely manner. This could cause delays in delivery of our products, harm our relationships with our customers,distributors and users, and adversely affect our results of operations. We have granted, and may continue to grant, share awards under our share incentive plans, which may result in increased share-based compensationexpenses. We have granted share-based compensation awards, including share options and restricted shares, to various employees, key personnel and othernon-employees to incentivize performance and align their interests with ours. We adopted a share incentive plan on December 30, 2010, or the 2010 Plan, asecond share incentive plan on November 18, 2013, as supplemented, or the 2013 Plan, and a third share incentive plan on April 24, 2014, as supplemented,or the 2014 plan. Under the 2010 Plan, we are authorized to issue a maximum number of 26,822,828 common shares of our company upon exercise of theoptions or other types of awards (excluding an aggregate of 8,410,200 shares already issued to the directors who are our founders upon exercise of founderoptions, which were not granted pursuant to the 2010 Plan). As of March 31, 2018, options to purchase a total of 349,815 common shares of our companywere outstanding under the 2010 Plan. As of March 31, 2018, 4,830,315 restricted shares (excluding those forfeited) have been granted to certain executiveofficers and other employees under the 2010 Plan. Under the 2013 Plan, we are authorized to issue a maximum number of 9,073,732 restricted shares tomembers of our senior management, counsel or consultant to our company. As of March 31, 2018, 7,089,155 restricted shares (excluding those forfeited) havebeen granted to certain executive officers and other employees under the 2013 Plan. Under the 2014 Plan, we are authorized to issue a maximum number of14,195,412 restricted shares to our directors, officers, employees and advisors or consultants to our company. As of March 31, 2018, 10,305,350 restrictedshares (excluding those forfeited) have been granted to certain executive officers and other employees under the 2014 Plan. As of March 31, 2018, ourunrecognized share-based compensation expenses relating to the restricted shares granted under each of the 2010 Plan, the 2013 Plan and the 2014 Planamounted to US$8.0 million, US$0.9 million and US$6.4 million, respectively. See “Item 6. Directors, Senior Management and Employees—B.Compensation—Share incentive plans” for details. We will issue the equivalent number of common shares upon the vesting and exercise of these options. The amount of these expenses is based on thefair value of the share-based compensation award we granted. The expenses associated with share-based compensation have affected our net income and mayreduce our net income in the future, and any additional securities issued under share-based compensation schemes will dilute the ownership interests of ourshareholders, including holders of our ADSs. We believe the granting of incentive awards is of significant importance to our ability to attract and retain keypersonnel and employees, and we will continue to grant stock options, restricted shares and other share awards to employees in the future. As a result, ourexpenses associated with share-based compensation may increase, which may have an adverse effect on our results of operations. The continuing and collaborative efforts of our senior management and key employees are crucial to our success, and our business may be harmed if wewere to lose their services. Our success depends on the continual efforts and services of our senior management team. If one or more of our executives or other key personnel areunable or unwilling to continue to provide services to us, we may not be able to find suitable replacements easily or at all. Competition for management andkey personnel in our industry is intense and the pool of qualified candidates is limited. We may not be able to retain the services of our executives or keypersonnel, or attract and retain experienced executives or key personnel in the future. If any of our executive officers or key employees joins a competitor orforms a competing company, we may lose advertisers, know-how and key professionals and staff members. Each of our executive officers has entered into anemployment agreement (including a non-compete provision) with us. However, if any dispute arises between us and our executives or key employees, theseagreements may not be enforceable in China, where these executives and key employees reside, in light of uncertainties with China’s legal system. 22 In addition, while we often grant additional incentive shares to management personnel and other key employees after their hire dates, the initialgrants are usually much larger than subsequent grants. Employees may be more likely to leave us after their initial incentive share grant fully vests, especiallyif the value of the incentive shares has significantly appreciated in value relative to the exercise price. If any member of our senior management team or otherkey personnel leaves our company, our ability to successfully operate our business and execute our business strategy could be impaired. We may not be able to effectively identify or pursue targets for acquisitions or investment, even if we complete such transactions, we may be unable tosuccessfully integrate the acquired businesses into, or realize anticipated benefits to, our business, and our equity investments may suffer impairment lossas a result of unsatisfactory target company performance, each of which may adversely affect our growth and results of operations. We have in the past and may in the future selectively acquire or invest in other businesses, including those that complement our existing business.We may not, however, be able to identify suitable targets for acquisitions or investments in the future. Even if we are able to identify suitable candidates, wemay be unable to complete a transaction on terms commercially acceptable to us. If we fail to identify appropriate candidates or complete the desiredtransactions, our growth may be impeded. If the target companies we invest in produce unsatisfactory results, we may suffer impairment loss in our equityinvestment. Even if we complete the desired acquisitions or investment, such acquisitions and investment may expose us to new operational, regulatory, marketand geographic risks and challenges, including: ·diversion of our management’s attention and other resources from our existing business; ·our inability to maintain the key business relationships and the reputation of the businesses we acquire or invest in; ·our inability to retain key personnel of the acquired or invested company; ·uncertainty of entry into markets in which we have limited or no prior experience and in which competitors have stronger market positions; ·failure to comply with laws and regulations as well as industry or technical standards of the markets into which we expand; ·our dependence on unfamiliar affiliates and partners of the companies we acquire or invest in; ·unsatisfactory performance of the businesses we acquire or invest in; ·our responsibility for the liabilities associated with the businesses we acquire, including those that we may not anticipate; ·goodwill impairment risks associated with the businesses that we acquire; ·our inability to integrate acquired technology into our business and operations; ·our inability to develop and maintain a successful business model and to monetize and generate revenues from the businesses we acquire; and ·our inability to maintain internal standards, controls, procedures and policies. 23 Any of these events could disrupt our ability to manage our business. These risks could also result in our failure to derive the intended benefits ofthe acquisitions or investments, and we may be unable to recover our investment in such initiatives or may have to recognize impairment charges as a result. Furthermore, the financing and payment arrangements we use in any acquisition could have a negative impact on you as an investor, because if weissue shares in connection with an acquisition, your holdings could be diluted. Moreover, if we take on significant debt to finance such acquisitions, wewould incur additional interest expenses, which would divert resources from our working capital and potentially have a material adverse impact on ourresults of operations. Strategic alliances, investments or acquisitions may have a material and adverse effect on our business, reputation, results of operations and financialcondition. We may enter into strategic alliances with various third parties to further our business purposes from time to time. Strategic alliances with thirdparties could subject us to a number of risks, including risks associated with sharing proprietary information, non-performance by the counterparty, and anincrease in expenses incurred in establishing new strategic alliances, any of which may materially and adversely affect our business. We may have littleability to control or monitor their actions. To the extent the third parties suffer negative publicity or harm to their reputations from events relating to theirbusiness, we may also suffer negative publicity or harm to our reputation by virtue of our association with such third parties. We have in the past invested in or acquired additional assets, technologies or businesses that are complementary to our existing business. If we arepresented with appropriate opportunities, we may continue to do so in the future. Investments or acquisitions and the subsequent integration of new assetsand businesses into our own would require significant attention from our management and could result in a diversion of resources from our existing business,which in turn could have an adverse effect on our business operations. The costs of identifying and consummating investments and acquisitions may besignificant. We may also incur significant expenses in obtaining necessary approvals from relevant government authorities in China and elsewhere in theworld. In addition, investments and acquisitions could result in the use of substantial amounts of cash, potentially dilutive issuances of equity securities andexposure to potential unknown liabilities or legal risks of the acquired business. The cost and duration of integrating newly acquired businesses could alsomaterially exceed our expectations. Any such negative developments could have a material adverse effect on our business, financial condition and results ofoperations. Our business, financial condition and results of operations, as well as our ability to obtain financing, may be adversely affected by the downturn in theglobal or Chinese economy. The industries in which we operate, including the mobile internet industry, may be affected by economic downturns. For example, a prolongedslowdown in the world economy, including in the Chinese economy, may lead to a reduced amount of mobile internet advertising, which could materiallyand adversely affect our business, financial condition and results of operations. In addition, certain of our products and services may be viewed asdiscretionary by our users, who may choose to discontinue or reduce spending on such products and services during an economic downturn. In such an event,our ability to retain existing users and increase new users will be adversely affected, which would in turn negatively impact our business and results ofoperations. Moreover, a slowdown or disruption in the global or Chinese economy may have a material and adverse impact on financings available to us. Theweakness in the economy could erode investor confidence, which constitutes the basis of the credit market. The unstable economy affecting the financialmarkets and banking system may significantly restrict our ability to obtain financing in the capital markets or from financial institutions on commerciallyreasonable terms, or at all. Although we are uncertain about the extent to which the global financial and economic fluctuations and slowdown of Chineseeconomy may impact our business in the short-term and long-term, there is a risk that our business, results of operations and prospects would be materiallyand adversely affected by any global economic downturn or disruption or slowdown of Chinese economy. 24 Our operations depend on the performance of the internet infrastructure in China. The successful operation of our business depends on the performance of the internet infrastructure and telecommunications networks in China. InChina, almost all access to the internet is maintained through state-owned telecommunications operators under the administrative control and regulatorysupervision of the MIIT. Moreover, we have entered into contracts with various subsidiaries of a limited number of telecommunications service providers ineach province for network-related services. On the one hand, if the internet industry in China does not grow as quickly as expected, our business andoperations will be negatively affected. We have limited access to alternative networks or services in the event of disruptions, failures or other problems withChina’s internet infrastructure or the telecommunications networks provided by telecommunications service providers. In addition, our network and websiteregularly serve a large number of users and advertisers. With the expansion of our business, we may be required to upgrade our technology and infrastructureto keep up with the increasing traffic on our website. However, we have no control over the costs of the services provided by telecommunications serviceproviders. If the prices we pay for telecommunications and internet services rise significantly, our results of operations may be materially and adverselyaffected. If internet access fees or other charges to internet users increase, our user traffic may decline and our business may be harmed. On the other hand, ifthe internet industry grows faster than expected and we cannot react to the market demand in a timely manner in terms of our research and development effort,the user experience and the attractiveness of our services may be harmed, which will negatively impact our business and results of operations. If we fail to implement and maintain an effective system of internal control over financial reporting, we may be unable to accurately report our financialresults or prevent fraud or fail to meet our reporting obligations, and investor confidence in our company and the market price of our ADSs may beadversely affected. We are subject to reporting obligations under the U.S. securities laws. The SEC, as required under Section 404 of the Sarbanes-Oxley Act of 2002,adopted rules requiring every public company to include a management report on such company’s internal control over financial reporting in its annualreport, which contains management’s assessment of the effectiveness of our internal control over financial reporting. However, we were not subject to therequirement to provide attestation by our independent registered public accounting firm on effectiveness of internal control over financial reporting for theyear ended December 31, 2017 as we qualified as an “emerging growth company,” as defined in the JOBS Act, as of December 31, 2017. Once we cease to bean “emerging growth company,” our independent registered public accounting firm must attest to and report on the effectiveness of our internal control overfinancial reporting, unless we qualify for other exemptions. Our management has concluded that our internal control over financial reporting was ineffective as of December 31, 2017 due to one materialweakness, one significant deficiency and other control deficiencies in internal control over financial reporting that were identified as of December 31, 2014,which were not remediated as of December 31, 2017. A material weakness is a deficiency, or a combination of deficiencies, in internal control over financialreporting, such that there is a reasonable possibility that a material misstatement of the company’s annual or interim financial statements will not beprevented or detected on a timely basis. The material weakness is related to a lack of accounting resources in U.S. GAAP and SEC reporting requirements, andthe significant deficiency identified related to a lack of documented comprehensive U.S. GAAP accounting manuals and financial reporting procedures andthe lack of related implementation controls. See “Item 15. Controls and Procedures” for more details. Any failure to achieve and maintain effective internalcontrol over financial reporting could result in the loss of investor confidence in the reliability of our consolidated financial statements, which in turn couldharm our business and negatively impact the market price of our ADSs. Furthermore, we have incurred and anticipate that we will continue to incurconsiderable costs, management time and other resources in an effort to comply with Section 404 and other requirements of the Sarbanes-Oxley Act. We have limited business insurance coverage and any uninsured business disruption may have an adverse effect on our results of operations and financialcondition. Insurance companies in China currently do not offer as extensive an array of insurance products as insurance companies do in more developedeconomies. We have limited business liability or disruption insurance to cover our operations. Any uninsured occurrence of business disruption may result inour incurring substantial costs and the diversion of resources, which could have an adverse effect on our results of operations and financial condition. 25 We face risks related to natural disasters such as earthquakes and health epidemics and other outbreaks, which could significantly disrupt our operations. Our operations may be vulnerable to interruption and damage from natural and other types of catastrophes, including earthquakes, fire, floods, hail,windstorms, severe winter weather (including snow, freezing water, ice storms and blizzards), environmental accidents, power loss, communications failures,explosions, man-made events such as terrorist attacks and similar events. Due to their nature, we cannot predict the incidence, timing and severity ofcatastrophes. If any such catastrophe or extraordinary event occurs in the future, our ability to operate our business could be seriously impaired. Such eventscould make it difficult or impossible for us to deliver our services and products to our users and could decrease demand for our products. As we do not carryproperty insurance and significant time could be required to resume our operations, our financial position and results of operations could be materially andadversely affected in the event of any major catastrophic event. In addition, our business could be adversely affected by the outbreak of pandemics such as influenza A (H1N1), avian influenza, H7N9 or severeacute respiratory syndrome (SARS). Any occurrence of these pandemic diseases or other adverse public health developments in China or elsewhere couldseverely disrupt our staffing or the staffing of our business partners, including our advertisers, and otherwise reduce the activity levels of our work force andthe work force of our business partners, causing a material and adverse effect on our business operations. Risks related to our corporate structure If the PRC government finds that the agreements that establish the structure for operating our businesses in China do not comply with PRC governmentalrestrictions on foreign investment in internet-related business and foreign investors’ mergers and acquisition activities in China, or if these regulations orthe interpretation of existing regulations change in the future, we could be subject to severe penalties or be forced to relinquish our interests in thoseoperations. Current PRC laws and regulations place certain restrictions on foreign ownership of companies that engage in internet businesses, including theprovision of online game and online advertising services. For example, foreign investors’ equity interests in value-added telecommunication serviceproviders may not exceed 50%. In addition, foreign investors are prohibited from investing in or operating entities engaged in, among others, internetcultural operating service (including online game operation services), internet news service, and online transmission of audio-visual programs service. We area Cayman Islands company and Giganology (Shenzhen) Ltd., or Giganology Shenzhen and Xunlei Computer (Shenzhen) Co., Ltd., or Xunlei Computer, ourPRC subsidiaries, are considered foreign-invested enterprises. Accordingly, neither of these two PRC subsidiaries is eligible to provide value-addedtelecommunication services and the aforementioned internet related services in China. As a result, we conduct our operations in China principally throughcontractual arrangements among Giganology Shenzhen and Shenzhen Xunlei and its shareholders. Shenzhen Xunlei or its subsidiaries hold the licenses andpermits necessary to conduct our resource discovery network, online advertising, online games, cloud computing and related businesses in China, andShenzhen Xunlei hold various operating subsidiaries that conduct a majority of our operations in China. Our contractual arrangements with Shenzhen Xunleiand its shareholders enable us to exercise effective control over Shenzhen Xunlei and Shenzhen Xunlei’s operating subsidiaries and hence treat them as ourconsolidated entities and consolidate their results. For a detailed discussion of these contractual arrangements, see “Item 4. Information on the Company—C.Organizational Structure.” We cannot assure you, however, that we will be able to enforce these contracts. Although we have been advised by Zhong Lun Law Firm, our PRClegal counsel, that each contract under these contractual arrangements with Shenzhen Xunlei and its shareholders is valid, binding and enforceable undercurrent PRC laws and regulations, we cannot assure you that the PRC government would agree that these contractual arrangements comply with PRClicensing, registration or other regulatory requirements, with existing policies or with requirements or policies that may be adopted in the future. PRC lawsand regulations governing the validity of these contractual arrangements are uncertain and the relevant government authorities have broad discretion ininterpreting these laws and regulations. If the PRC government determines that we do not comply with applicable laws and regulations, it could revoke ourbusiness and operating licenses, require us to discontinue or restrict our operations, restrict our right to collect revenues, block our website, require us torestructure our operations, impose additional conditions or requirements with which we may not be able to comply, or take other regulatory or enforcementactions against us that could be harmful to our business. The imposition of any of these penalties would result in a material and adverse effect on our abilityto conduct our business. 26 We rely on contractual arrangements with our variable interest entity in China and its shareholders for our operations, which may not be as effective asdirect ownership in providing operational control the variable interest entity and its subsidiaries. Since PRC laws restrict foreign equity ownership in companies engaged in internet business in China, we rely on contractual arrangements withShenzhen Xunlei, our VIE, and the shareholders of Shenzhen Xunlei to operate our business in China. If we had direct ownership of Shenzhen Xunlei, wewould be able to exercise our rights as a shareholder to effect changes in the board of directors of Shenzhen Xunlei, which in turn could effect changes at themanagement level, subject to any applicable fiduciary obligations. However, under the current contractual arrangements, we rely on Shenzhen Xunlei and itsshareholders’ performance of their contractual obligations to exercise effective control. In addition, our operating contract with Shenzhen Xunlei has a termof ten years, which is subject to Giganology Shenzhen’s unilateral termination right and may be extended as requested by Giganology Shenzhen. In general,none of Shenzhen Xunlei or its shareholders may terminate the contracts prior to the expiration date. However, the shareholders of Shenzhen Xunlei may notact in the best interests of our company or may not perform their obligations under these contracts, including the obligation to renew these contracts whentheir initial contract term expires. Such risks exist throughout the period in which we intend to operate our business through the contractual arrangementswith Shenzhen Xunlei. We may replace the shareholders of Shenzhen Xunlei at any time pursuant to our contractual arrangements with Shenzhen Xunlei andits shareholders. However, if any dispute relating to these contracts remains unresolved, we will have to enforce our rights under these contracts through theoperations of PRC law and courts and therefore will be subject to uncertainties in the PRC legal system. See “—Any failure by Shenzhen Xunlei or itsshareholders to perform their obligations under our contractual arrangements with them may have a material adverse effect on our business” and “Item 4.Information on the Company—C. Organizational Structure.” Therefore, these contractual arrangements may not be as effective as direct ownership inproviding us with control over Shenzhen Xunlei. Any failure by Shenzhen Xunlei or its shareholders to perform their obligations under our contractual arrangements with them may have a materialadverse effect on our business. Shenzhen Xunlei or its shareholders may fail to take certain actions required for our business or follow our instructions despite their contractualobligations to do so. If they fail to perform their obligations under their respective agreements with us, we may have to rely on legal remedies under PRC law,including seeking specific performance or injunctive relief, which may not be effective. As of the date of this annual report, Mr. Sean Shenglong Zou, our co-founder and director, owned 76% of the equity interest in Shenzhen Xunlei, our variable interest entity. Under the equity pledge agreement amongGiganology Shenzhen and the shareholders of Shenzhen Xunlei, as amended, the shareholders of Shenzhen Xunlei have pledged all of their equity interestsin Shenzhen Xunlei to Giganology Shenzhen to guarantee Shenzhen Xunlei and its shareholders’ performance of their respective obligations under therelated contractual arrangements. In addition, the shareholders of Shenzhen Xunlei have completed the registration of equity pledge under the equity pledgeagreement with the competent governmental authority. If any of the shareholders of Shenzhen Xunlei, especially Mr. Sean Shenglong Zou due to hissignificant equity interest in Shenzhen Xunlei, fails to perform his or her obligations under the contractual arrangements, we may have to enforce theseagreements to transfer his or her equity interests to another appointee of Giganology Shenzhen. Moreover, the exercise of call options under the equity interests disposal agreement, the intellectual properties purchase option agreement andcertain other contractual arrangements will be subject to the review and approval of competent governmental authorities and incur additional expenses. All of these contractual arrangements are governed by PRC law and provide for the resolution of disputes through arbitration in the PRC.Accordingly, these contracts would be interpreted in accordance with PRC law and any disputes would be resolved in accordance with PRC legal procedures.The legal environment in the PRC is not as developed as in certain other jurisdictions, such as the United States. As a result, uncertainties in the PRC legalsystem could limit our ability to enforce these contractual arrangements, which may make it difficult to exert effective control over our variable interestentity and its subsidiaries, and our ability to conduct our business may be adversely affected. 27 Contractual arrangements with our variable interest entity may result in adverse tax consequences to us. Under applicable PRC tax laws and regulations, arrangements and transactions among related parties may be subject to audit or scrutiny by the PRCtax authorities within ten years after the taxable year when the arrangements or transactions are conducted. See “Item 4. Information on the Company—B.Business Overview—Regulation—Regulation on tax—PRC enterprise income tax.” We could face material and adverse tax consequences if the PRC taxauthorities were to determine that the contractual arrangements among Giganology Shenzhen, our wholly-owned subsidiary in China, and Shenzhen Xunlei,our variable interest entity in China and its shareholders, as well as the intellectual property framework agreement between Xunlei Computer and ShenzhenXunlei were not entered into on an arm’s-length basis and therefore constituted unfavorable transfer pricing arrangements. Unfavorable transfer pricingarrangements could, among other things, result in an upward adjustment on taxation, and the PRC tax authorities may impose interest on late payments onShenzhen Xunlei, for the adjusted but unpaid taxes. Our results of operations may be materially and adversely affected if Shenzhen Xunlei’s tax liabilitiesincrease significantly or if it is required to pay interest on late payments. The shareholders of Shenzhen Xunlei may have potential conflicts of interest with us, which may materially and adversely affect our business. Sean Shenglong Zou, Hao Cheng, Fang Wang, Jianming Shi and Guangzhou Shulian Information Investment Co., Ltd. are shareholders of ShenzhenXunlei. We provide no incentives to the shareholders of Shenzhen Xunlei for the purpose of encouraging them to act in our best interests in their capacity asthe shareholders of Shenzhen Xunlei. We may replace the shareholders of Shenzhen Xunlei at any time pursuant to the currently effective equity optionagreements between us and these shareholders. As a director and/or executive officer of our company, Mr. Zou and Mr. Cheng each has a duty of loyalty and care to us under Cayman Islands law.We are not aware that other publicly listed companies in China with a similar corporate and ownership structure as ours have brought conflicts of interestclaims against the shareholders of their respective variable interest entities. However, we cannot assure you that when conflicts arise, the shareholders ofShenzhen Xunlei will act in the best interests of our company or that conflicts will be resolved in our favor. If we cannot resolve any conflicts of interest ordisputes between us and the shareholders of Shenzhen Xunlei, we would have to rely on legal proceedings, which may be expensive, time-consuming anddisruptive to our operations. There is also substantial uncertainty as to the outcome of any such legal proceedings. We may rely principally on dividends and other distributions on equity paid by our PRC subsidiaries to fund any cash and financing requirements we mayhave. Any limitation on the ability of Giganology Shenzhen and Xunlei Computer to pay dividends to us could have a material adverse effect on our abilityto conduct our business. We are a holding company and we may rely principally on dividends and other distributions on equity paid by our wholly-owned PRC subsidiariesincluding Giganology Shenzhen and Xunlei Computer, for our cash and financing requirements, including the funds necessary to pay dividends and othercash distributions to our shareholders and service any debt we may incur. If Giganology Shenzhen incurs debt on its own behalf in the future, the instrumentsgoverning the debt may restrict its ability to pay dividends or make other distributions to us. In addition, the PRC tax authorities may require us to adjust ourtaxable income under the contractual arrangements Giganology Shenzhen currently has in place with Shenzhen Xunlei, our variable interest entity, as well asthe intellectual property framework agreement between Xunlei Computer and Shenzhen Xunlei, in a manner that would materially and adversely affect itsability to pay dividends and other distributions to us. As of December 31, 2017, we had cash or cash equivalents of approximately RMB436.8 million(US$66.9 million) and US$2.8 million located within the PRC, of which RMB313.9 million (US$48.0 million) is held by Shenzhen Xunlei and itssubsidiaries. The transfer of all the cash or cash equivalents is subject to PRC government’s restrictions on currency conversion. Under PRC laws and regulations, Giganology Shenzhen and Xunlei Computer, as wholly foreign-owned enterprises in the PRC, may pay dividendsonly out of its accumulated after-tax profits as determined in accordance with PRC accounting standards and regulations. In addition, wholly foreign-ownedenterprises such as Giganology Shenzhen and Xunlei Computer are required to set aside at least 10% of their accumulated after-tax profits each year, if any,to fund certain statutory reserve funds, until the aggregate amount of such a fund reaches 50% of their respective registered capital. At their discretion, whollyforeign-owned enterprises may allocate a portion of their after-tax profits based on PRC accounting standards to staff welfare and bonus funds. These reservefunds and staff welfare and bonus funds are not distributable as cash dividends. Any limitation on the ability of Giganology Shenzhen and Xunlei Computerto pay dividends or make other distributions to us could materially and adversely limit our ability to grow, make investments or acquisitions that could bebeneficial to our business, pay dividends, or otherwise fund and conduct our business. See also “—Risks related to doing business in China—Our globalincome may be subject to PRC taxes under the PRC EIT Law, which may have a material adverse effect on our results of operations.” 28 PRC regulation of loans to, and direct investment in, PRC entities by offshore holding companies and governmental control of currency conversion mayrestrict or prevent us from making loans to our PRC subsidiaries and variable interest entity and its subsidiaries or making additional capitalcontributions to our PRC subsidiaries, which may materially and adversely affect our liquidity and our ability to fund and expand our business. We may (i) make additional capital contributions to our PRC subsidiaries, (ii) establish new PRC subsidiaries and make capital contributions tothese new PRC subsidiaries, (iii) make loans to our PRC subsidiaries or variable interest entity and its subsidiaries, or (iv) acquire offshore entities withbusiness operations in China in an offshore transaction. However, most of these uses are subject to PRC regulations and approvals. For example: ·capital contributions to our PRC subsidiaries, whether existing ones or newly established ones, must complete the record-filing procedures bythe Ministry of Commerce or its local counterparts; ·loans by us to our PRC subsidiaries, which are foreign-invested enterprises, to finance their respective activities cannot exceed statutory limitsand must be registered with the PRC State Administration of Foreign Exchange, or SAFE, or its local branches; and ·loans by us to our variable interest entity, which is a domestic PRC entity, may not exceed the statutory limit, and any medium or long-termloan we extend to our variable interest entity must be recorded and registered by the National Development and Reform Commission and SAFEor its local branches. On August 29, 2008, SAFE promulgated the Circular on the Relevant Operating Issues Concerning the Improvement of the Administration of thePayment and Settlement of Foreign Currency Capital of Foreign Invested Enterprises, or SAFE Circular No. 142, regulating the conversion by a foreign-invested enterprise of foreign currency registered capital into Renminbi by restricting how the converted Renminbi may be used. SAFE Circular No. 142provides that the Renminbi capital converted from foreign currency registered capital of a foreign-invested enterprise may only be used for purposes withinthe business scope approved by the applicable governmental authority and unless otherwise provided by law, such Renminbi capital may not be used forequity investments within the PRC. SAFE also strengthened its oversight of the flow and use of the Renminbi capital converted from foreign currencyregistered capital of a foreign-invested company. The use of such Renminbi capital may not be altered without SAFE approval, and such Renminbi capitalmay not in any case be used to repay Renminbi loans if the proceeds of such loans have not been used. Violations of SAFE Circular No. 142 could result insevere monetary or other penalties. On March 30, 2015, SAFE issued SAFE Circular No. 19, which took effect and replaced SAFE Circular No. 142 as of June1, 2015 and the Notice of the State Administration of Foreign Exchange on Reforming and Standardizing the Policy on the Management of ForeignExchange Settlement under Capital Account, or SAFE Circular No. 16, which became effective on June 9, 2016. Although SAFE Circular No. 19 and SAFECircular No. 16 allow for the use of RMB converted from the foreign currency denominated capital for equity investments in the PRC, the restrictions willcontinue to apply as to foreign-invested enterprises’ use of the converted RMB for purposes beyond the business scope, for the loans to non-associatedcompanies or issuing inter-company RMB loans. We expect that if we convert the net proceeds we received from our initial public offering into Renminbipursuant to SAFE Circular No. 16 and SAFE Circular No. 19, our use of Renminbi funds will be for purposes within the approved business scope of our PRCsubsidiaries. The business scopes of Giganology Shenzhen and Xunlei Computer include “technical services,” which we believe permits GiganologyShenzhen to purchase or lease servers and other equipment for its own technical data and research and to provide operational support to our variable interestentity and its subsidiaries. However, we may not be able to use such Renminbi funds to make equity investments in certain entities in the PRC through our PRC subsidiaries. 29 We may lose the ability to use and enjoy assets held by our variable interest entity and its subsidiaries that are important to the operation of our business ifany of such entities goes bankrupt or becomes subject to a dissolution or liquidation proceeding. As part of our contractual arrangements with our variable interest entity, our variable interest entity and its subsidiaries hold certain assets that areimportant to the operation of our business, including patents for the proprietary technology and related domain names and trademarks. If any of our variableinterest entity or its subsidiaries goes bankrupt and all or part of its assets become subject to liens or rights of third-party creditors, we may be unable tocontinue some or all of our business activities, which could materially and adversely affect our business, financial condition and results of operations. Underthe contractual arrangements, our variable interest entity and its subsidiaries may not, in any manner, sell, transfer, mortgage or dispose of their assets or legalor beneficial interests in the business without our prior consent. If our variable interest entity undergoes a voluntary or involuntary liquidation proceeding,the unrelated third-party creditors may claim rights to some or all of these assets, thereby hindering our ability to operate our business, which couldmaterially and adversely affect our business, financial condition and results of operations. Substantial uncertainties exist with respect to the enactment timetable, interpretation and implementation of draft PRC Foreign Investment Law and howit may impact the viability of our current corporate structure, corporate governance and business operations. The MOFCOM published a discussion draft of the proposed Foreign Investment Law in January 2015 aiming to, upon its enactment, replace the trioof existing laws regulating foreign investment in China, namely, the Sino-foreign Equity Joint Venture Enterprise Law, the Sino-foreign Cooperative JointVenture Enterprise Law and the Wholly Foreign-invested Enterprise Law, together with their implementation rules and ancillary regulations. The draftForeign Investment Law embodies an expected PRC regulatory trend to rationalize its foreign investment regulatory regime in line with prevailinginternational practice and the legislative efforts to unify the corporate legal requirements for both foreign and domestic investments. Substantial uncertaintiesexist with respect to its enactment timetable, interpretation and implementation. The draft Foreign Investment Law, if enacted as proposed, may materiallyimpact the viability of our current corporate structure, corporate governance and business operations in many aspects. Among other things, the draft Foreign Investment Law expands the definition of foreign investment and introduces the principle of “actual control”in determining whether the investment in China is made by a foreign investor or a PRC domestic investor. The draft Foreign Investment Law specificallyprovides that an entity established in China but “controlled” by foreign investors will be treated as a foreign investor, whereas an entity set up in a foreignjurisdiction would nonetheless be, upon market entry clearance by the MOFCOM or its local branches, treated as a PRC domestic investor provided that theentity is “controlled” by PRC entities and/or citizens. In this connection, “control” is broadly defined in the draft law to cover, among others, having thepower to exert decisive influence, via contractual or trust arrangements, over the subject entity’s operations, financial matters or other key aspects of businessoperations. If the foreign investment falls within a “negative list”, to be separately issued by the State Council in the future, market entry clearance by theMOFCOM or its local branches would be required. Otherwise, all foreign investors may make investments on the same terms as Chinese investors withoutbeing subject to additional approval from the government authorities as mandated by the existing foreign investment legal regime. The “variable interest entity” structure, or VIE structure, has been adopted by many PRC-based companies, including us, to obtain necessarylicenses and permits in the industries that are currently subject to foreign investment restrictions in China. See “—Risks Related to Our Corporate Structure—If the PRC government finds that the agreements that establish the structure for operating our businesses in China do not comply with PRC governmentalrestrictions on foreign investment in internet-related business and foreign investors’ mergers and acquisition activities in China, or if these regulations or theinterpretation of existing regulations change in the future, we could be subject to severe penalties or be forced to relinquish our interests in those operations,”and “Item 4. Information on the Company—C. Organizational Structure.” Under the draft Foreign Investment Law, if a variable interest entity is ultimatecontrolled by a foreign investor via contractual arrangement, it would be deemed as a foreign investment. Accordingly, for the companies with a VIEstructure in an industry category that is on the “negative list”, the VIE structure may be deemed legitimate only if the ultimate controlling person(s) is/ are ofPRC nationality (either PRC individual, or PRC government and its branches or agencies) Conversely, if the actual controlling person(s) is/are of foreignnationalities, then the variable interest entities will be treated as foreign invested enterprises and any operation in the industry category on the “negative list”without market entry clearance may be considered as illegal. 30 As of the date of this annual report, over 50% of the voting power of our issued and outstanding share capital is controlled by PRC nationals.However, the draft Foreign Investment Law has not taken a position on what actions will be taken with respect to the existing companies with a VIE structure,whether or not these companies are controlled by Chinese parties, although a few possible options were proffered to solicit comments from the public on thispoint. Under these options, a company with VIE structure that is engaged in a business set forth in a “negative list” to be published at the time of theenactment of the new Foreign Investment Law has either the option or obligation to disclose its corporate structure to the authorities, while the authorities,after reviewing the ultimate control structure of the company, may either permit the company to continue its business by maintaining the VIE structure (whenthe company is deemed ultimately controlled by PRC citizens), or require the company to dispose of its businesses and/or VIE structure based onconsideration of the particular circumstances involved. Moreover, it is uncertain whether the value-added telecommunication services and other internetrelated services, which our VIE provides, will be subject to the foreign investment restrictions or prohibitions set forth in the “negative list” to be issued. Ifthe enacted version of the Foreign Investment Law and the final “negative list” mandate further actions, such as MOFCOM market entry clearance or certainrestructuring of our corporate structure and operations, to be completed by companies with existing VIE structure like us, we will face substantialuncertainties as to whether these actions can be timely completed, or at all, and our business and financial condition may be materially and adverselyaffected. The draft Foreign Investment Law, if enacted as proposed, may also materially impact our corporate governance practice and increase ourcompliance costs. For instance, the draft Foreign Investment Law imposes stringent ad hoc and periodic information reporting requirements on foreigninvestors and the applicable foreign invested entities. Aside from investment implementation report and investment amendment report that are required ateach investment and alteration of investment specifics, an annual report is mandatory, and large foreign investors meeting certain criteria are required toreport on a quarterly basis. Any company found to be non-compliant with the information reporting obligations may potentially be subject to fines and/oradministrative or criminal liabilities, and the persons directly responsible may be subject to criminal liabilities. Risks related to doing business in China Changes in China’s economic, political or social conditions or government policies could have a material adverse effect on our business and operations. Substantially all of our assets and operations are located in China. Accordingly, our business, financial condition, results of operations and prospectsmay be influenced to a significant degree by political, economic and social conditions in China generally and by continued economic growth in China as awhole. The Chinese economy differs from the economies of most developed countries in many respects, including the level of government involvement,level of development, growth rate, control of foreign exchange and allocation of resources. Although the Chinese government has implemented measuresemphasizing the utilization of market forces for economic reform, the reduction of state ownership of productive assets, and the establishment of improvedcorporate governance in business enterprises, a substantial portion of productive assets in China is still owned by the government. In addition, the Chinesegovernment continues to play a significant role in regulating industry development by imposing industrial policies. The Chinese government also exercisessignificant control over China’s economic growth through allocating resources, controlling payment of foreign currency-denominated obligations, settingmonetary policy, and providing preferential treatment to particular industries or companies, such as those qualified to operate in free trade zones designatedin certain major cities in China. While the Chinese economy has experienced significant growth over the past decades, growth has been uneven, both geographically and amongvarious sectors of the economy and the rate of growth has been slowing. The Chinese government has implemented various measures to encourage economicgrowth and guide the allocation of resources. Some of these measures may benefit the overall Chinese economy, but may have a negative effect on us. Forexample, our financial condition and results of operations may be adversely affected by government control over capital investments or changes in taxregulations. In addition, in the past the Chinese government has implemented certain measures, including interest rate increases, to control the pace ofeconomic growth. 31 These measures may cause decreased economic activity in China, which may adversely affect our business and operating results. Regulation and censorship of information disseminated over the internet in China have adversely affected our business and may continue to adverselyaffect our business, and we may be liable for the digital media content on our platform. China has strict regulations governing telecommunication service providers, internet and wireless access and the distribution of news and otherinformation. Under these regulations, internet content providers, or ICPs, like us are prohibited from posting or displaying over the internet or wirelessnetworks content that, among other things, violates PRC laws and regulations. If an ICP finds that prohibited content is transmitted on its website or stored inits system, it must terminate the transmission of such information or delete such information immediately and keep records and report to relevant authorities.Failure to comply with these requirements could lead to the revocation of the VATS License, which is required for our ICP services and other requiredlicenses and the closure of the offending websites, and cloud network operators or website operators may also be held liable for prohibited content displayedon, retrieved from or linked to such network or website. However, efforts to constantly self-monitor in order to comply with these requirements couldnegatively impact user experience and lead to a decline in user numbers. The Chinese government intensified its efforts to remove inappropriate content disseminated over the internet and wireless networks, and our effortsto monitor content on our platform and website led to a decline in subscriber numbers in the past few years. In April 2014, the Chinese government initiated acampaign to enhance and enforce its scrutiny on internet content in China, particularly for pornographic content, and various websites were subject topenalties and in some cases outright suspension of website operations. We regularly conducted internal compliance investigation to ensure that the contenttransmitted by our products is in compliance with the standards set out by the authorities. To date, we have deleted millions of cached files, blocked over onemillion digital files and added thousands of key words to our automatic keyword filtration system. In addition, we permitted temporary suspension of servicesby about 207,000 existing subscribers as of the end of 2017. We may experience still further decline in user and subscriber numbers as we continue in ourefforts to comply with the rules and regulations of the Chinese government. Uncertainties with respect to the PRC legal system could adversely affect us. We conduct our business primarily through our PRC subsidiaries and variable interest entity and its subsidiaries in China. Our operations in Chinaare governed by PRC laws and regulations. Giganology Shenzhen is a foreign-invested enterprise and is subject to laws and regulations applicable to foreigninvestment in China and, in particular, laws applicable to foreign-invested enterprises. The PRC legal system is a civil law system based on written statutes.Unlike the common law system, prior court decisions under the civil law system may be cited for reference but have limited precedential value. Over the past three decades, the PRC government has enacted legislation that has significantly enhanced the protections afforded to various forms offoreign investments in China. However, China has not developed a fully integrated legal system, and recently enacted laws and regulations may notsufficiently cover all aspects of economic activities in China. In particular, the interpretation and enforcement of these laws and regulations involveuncertainties. Since PRC administrative and court authorities have significant discretion in interpreting and implementing statutory and contractual terms, itmay be difficult to evaluate the outcome of administrative and court proceedings and the level of legal protection we enjoy. These uncertainties may affectour judgment on the relevance of legal requirements and our ability to enforce our contractual or tort rights. In addition, the regulatory uncertainties may beexploited through unmerited or frivolous legal actions or threats in attempts to extract payments or benefits from us. Furthermore, the PRC legal system is based in part on government policies and internal rules, some of which are not published on a timely basis or atall and may have retroactive effect. As a result, we may not be aware of our violation of any of these policies and rules until sometime after the violation. Inaddition, any administrative and court proceedings in China may be protracted, resulting in substantial costs and diversion of resources and managementattention. 32 We believe that our patents, trademarks, trade secrets, copyrights, and other intellectual property are important to our business. We rely on acombination of patent, trademark, copyright and trade secret protection laws in China and other jurisdictions, as well as confidentiality procedures andcontractual provisions to protect our intellectual property and our brand. Protection of intellectual property rights in China may not be as effective as in theUnited States or other jurisdictions, and as a result, we may not be able to adequately protect our intellectual property rights, which could adversely affect ourrevenues and competitive position. We may be adversely affected by the complexity, uncertainties and changes in PRC regulations of internet-related business and companies. The PRC government extensively regulates the internet industry, including foreign ownership of, and the licensing and permit requirementspertaining to, companies in the internet industry. These internet-related laws and regulations are relatively new and evolving, and their interpretation andenforcement involve significant uncertainty. As a result, in certain circumstances it may be difficult to determine what actions or omissions may be deemed tobe in violations of applicable laws and regulations. Issues, risks and uncertainties relating to PRC regulation of the internet business include, but are notlimited to, the following: ·We only have contractual control over our resource discovery network and cloud computing. We do not own the resource discovery networkand cloud computing due to the restriction of foreign investment in businesses providing value-added telecommunication services in China,including internet content provision or CDN services. This may significantly disrupt our business, subject us to sanctions, compromiseenforceability of related contractual arrangements, or have other harmful effects on us. ·There are uncertainties relating to the regulation of the internet business in China, including evolving licensing practices and the requirementfor real-name registrations. This means that permits, licenses or operations at some of our companies may be subject to challenge, or we may failto obtain permits or licenses that may be deemed necessary for our operations or we may not be able to obtain or renew certain permits orlicenses. If we fail to maintain any of these required licenses or approvals, we may be subject to various penalties, including fines anddiscontinuation of or restriction on our operations. Any such disruption in our business operations may have a material and adverse effect onour results of operations. For example, we are providing mobile applications to mobile device users free of charge and we do not believe we, asan internet content provider, need to obtain a separate operating license in addition to the VATS License, which we have already obtained.Although we believe this is in line with the current market practice, there can be no assurance that we will not be required to apply for anoperating license for our mobile applications in the future and if so, we may not qualify or succeed in obtaining such license. ·Intensified government regulation of the internet industry in China could restrict our ability to maintain or increase our user base. For example,in January 2011, MIIT and seven other PRC central government authorities jointly issued a circular entitled Implementation Scheme regardingParental Guardianship Project for Minors Playing Online Games, under which online game operators are required to adopt various measures tomaintain a system to communicate with the parents or other guardians of minors playing their online games and are required to monitor theonline game activities of minors and suspend the accounts of minors if so required by their parents or guardians. These restrictions could limitour ability to increase our online game business among minors. ·New laws and regulations may be promulgated that will regulate internet activities, including online video, online games and onlineadvertising businesses. If these new laws and regulations are promulgated, additional licenses may be required for our operations. If ouroperations do not comply with these new regulations after they become effective, or if we fail to obtain any licenses required under these newlaws and regulations, we could be subject to penalties. ·In June 2010, MOC promulgated the Provisional Measures on the Administration of Online Games, or the Online Game Measures, whichbecame effective on August 1, 2010. The Online Game Measures provide that any entity engaging in online game operation activities shouldobtain an Online Culture Operating Permit and must meet certain requirements such as a minimum amount of the registered capital. Onlinegame developers are generally involved in the purchase of servers and bandwidth, the control and management of game data, the maintenanceof game systems and certain other maintenance tasks in our operation of online games. There exist uncertainties on MOCT’s interpretation andimplementation of these measures. If MOCT determines in the future that such Online Culture Operating Permit or relevant requirement apply tothe online game developers for their involvement in the online game operations, we may have to terminate our revenue sharing arrangementswith certain unqualified online game developers and may even be subject to various penalties, which may negatively impact our results ofoperations and financial condition. 33 The interpretation and application of existing PRC laws, regulations and policies and possible new laws, regulations or policies relating to theinternet industry have created substantial uncertainties regarding the legality of existing and future foreign investments in, and the businesses and activitiesof, internet businesses in China, including our business. For example, in September 2009, GAPPRFT and the National Office of Combating Pornography andIllegal Publications jointly published a notice, or Circular 13, which expressly prohibits foreign investors from participating in online game operatingbusiness via wholly owned, equity joint venture or cooperative joint venture investments in China, and from controlling and participating in such businessesdirectly or indirectly through contractual or technical support arrangements. Other government agencies with substantial regulatory authority over onlinegame operations and foreign investment entities in China, such as MIIT and MOCT, did not join GAPPRFT in issuing Circular 13. While Circular 13 isapplicable to us and our online game business on an overall basis, to date, GAPPRFT or SAPPRFT has not issued any interpretation of Circular 13 and, to ourknowledge, has not taken any enforcement action under Circular 13 against any company that relies on contractual arrangements with affiliated entities tooperate online games in China. We cannot assure you that we have obtained all the permits or licenses required for conducting our business in China or willbe able to maintain our existing licenses or obtain any new licenses required under any new laws or regulations. There are also risks that we may be found toviolate the existing or future laws and regulations given the uncertainty and complexity of China’s regulation of internet business. Subject to interpretation by the relevant authorities, it may not be possible for us to determine in all cases the type of content that could result inliability for us, especially if the Chinese government continues to maintain or strengthen its heightened scrutiny on internet content in China. We may not beable to control or restrict all of the digital media content generated or placed on our network by our users, despite our attempt to monitor and filter suchcontent. To the extent that regulatory authorities find any portion of our content on our network or website objectionable or requiring any license or permitthat we have not obtained, they may require us to limit or eliminate the dissemination of such information or otherwise curtail the nature of such content, andkeep records and report to relevant authorities, which may reduce our user traffic. In addition, we may be subject to significant penalties for violations ofthose regulations arising from prohibited content displayed on, retrieved from or uploaded to our network or website, including a suspension or shutdown ofour operations. The enforcement activities may be intensified in connection with any ongoing government campaigns. In addition, while we maintain aregular internal monitoring and compliance protocol, we cannot ascertain that we would not fall foul of any changing or new government regulations orstandards in the future. If we receive a public warning from the relevant government authorities or our licenses for acceleration services are revoked, ourreputation would be harmed and if the operation of our acceleration services or other products is suspended or shut down entirely or in part, our revenues andresults of operation may be materially and adversely affected. Furthermore, the internal compliance investigation and the removal of content may have amaterial impact on our cloud acceleration services, which in turn may lead to a decrease in users and have an adverse effect on our revenues and results ofoperations. To date, we have not been able to quantify the magnitude and extent of such impact. We may be sued by our game players and held liable for losses of virtual assets by such players, which may negatively affect our reputation and business,financial condition and results of operations. While playing online games or participating in other online activities, players acquire and accumulate some virtual assets, such as specialequipment and other accessories. Such virtual assets may be important to online game players and have monetary value and, in some cases, are sold for actualmoney. In practice, virtual assets can be lost for various reasons, often through unauthorized use of the game account of one user by other users andoccasionally through data loss caused by a delay of network service, a network crash or hacking activities. 34 Currently, there is no PRC law or regulation specifically governing virtual asset property rights. As a result, there is uncertainty as to who the legalowner of virtual assets is, whether and how the ownership of virtual assets is protected by law, and whether an operator of online games such as us would haveany liability to game players or other interested parties (whether in contract, tort or otherwise) for loss of such virtual assets. Based on recent PRC courtjudgments, the courts have typically held online game operators liable for losses of virtual assets by game players, and ordered online game operators toreturn the lost virtual items to game players or pay damages and losses. In case of a loss of virtual assets, we may be sued by our game players or users andheld liable for damages, which may negatively affect our reputation and business, financial condition and results of operations. Non-compliance with the laws or regulations governing virtual currency may result in penalties that could have a material adverse effect on our onlinegames business and results of operations. The issuance and use of “virtual currency” in the PRC has been regulated since 2007 in response to the growth of the online games industry inChina. In January 2007, the Ministry of Public Security, MOC, MIIT and GAPPRFT jointly issued a circular regarding online gambling which hasimplications for the use of virtual currency. To curtail online games that involve online gambling, as well as address concerns that virtual currency could beused for money laundering or illicit trade, the circular (a) prohibits online game operators from charging commissions in the form of virtual currency inrelation to winning or losing of games; (b) requires online game operators to impose limits on use of virtual currency in guessing and betting games; (c) bansthe conversion of virtual currency into real currency or property; and (d) prohibits services that enable game players to transfer virtual currency to otherplayers. On June 4, 2009, MOC and the Ministry of Commerce jointly issued a notice regarding strengthening the administration of online game virtualcurrency, or the Virtual Currency Notice. Furthermore, MOC issued the Online Game Measures in June 2010, which provides, among other things, that virtualcurrency issued by online game operators may only be used to exchange its own online game products and services and may not be used to pay for theproducts and services of other entities. We issue virtual currency to our clients for them to purchase various items to be used in online games and premium services. Although we believewe do not offer online game virtual currency transaction services, we cannot assure you that the PRC regulatory authorities will not take a view contrary toours. For example, certain virtual items we issue to users based on in-game milestones they achieve or time spent playing games are transferable andexchangeable for our virtual currency or the other virtual items we issue to users. If the PRC regulatory authorities deem such transfer or exchange a virtualcurrency transaction, then we may be deemed to be engaging in the issuance of virtual currency and we may also be deemed to be providing transactionplatform services that enable the trading of such virtual currency. Simultaneously engaging in both of these activities is prohibited under the VirtualCurrency Notice. In that event, we may be required to cease either our virtual currency issuance activities or such deemed “transaction service” activities andmay be subject to certain penalties, including mandatory corrective measures and fines. The occurrence of any of the foregoing could have a material adverseeffect on our online games business and results of operations. In addition, the Virtual Currency Notice prohibits online game operators from setting game features that involve the direct payment of cash orvirtual currency by players for the chance to win virtual items or virtual currency based on random selection through a lucky draw, wager or lottery. Thenotice also prohibits game operators from issuing currency to game players through means other than purchases with legal currency. Although we believethat we are generally in compliance with such requirements and have taken adequate measures to prevent any of the above-mentioned prohibited activities,we cannot assure you that the PRC regulatory authorities will not take a view contrary to ours and deem such feature as prohibited by the Virtual CurrencyNotice, thereby subjecting us to penalties, including mandatory corrective measures and fines. The occurrence of any of the foregoing could materially andadversely affect our online games business and results of operations. Intensified government regulation of the internet industry in China could restrict our ability to maintain or increase our user base. The PRC government has, in recent years, intensified regulation on various aspects of the internet industry in China. For example, in January 2011,MIIT and seven other PRC central government authorities jointly issued a circular entitled Implementation Scheme regarding Parental Guardianship Projectfor Minors Playing Online Games, under which online game operators are required to adopt various measures to maintain a system to communicate with theparents or other guardians of minors playing their online games and are required to monitor the online game activities of minors and suspend the accounts ofminors if so required by their parents or guardians. These restrictions could limit our ability to increase our online game business among minors. See “Item 4.Information on the Company—B. Business Overview—Regulation—Regulation on anti-fatigue system, real-name registration system and parentalguardianship project.” Failure to implement these restrictions, if detected by the relevant government agencies, may result in fines and other penalties for us,including the shutting down of our online games operations and license revocation. Furthermore, if these restrictions were expanded to apply to adult gameplayers in the future, our online games business could be materially and adversely affected. 35 Further, the PRC government has tightened its regulation of internet cafes in recent years. In particular, a large number of unlicensed internet cafeshave been closed. The PRC government has imposed higher capital and facility requirements for the establishment of internet cafes. Furthermore, the PRCgovernment’s policy, which encourages the development of a limited number of national and regional internet cafe chains and discourages the establishmentof independent internet cafes, may slow down the growth of internet cafes in China. In June 2002, the Ministry of Culture, together with other governmentauthorities, issued a joint notice, and in February 2004, the State Administration for Industry and Commerce issued another notice, suspending the issuanceof new internet cafe licenses. In May 2007, the State Administration for Industry and Commerce reiterated its position not to register any new internet cafes in2007. In 2008, 2009 and 2010, the Ministry of Culture, the State Administration for Industry and Commerce and other relevant government authorities,individually or jointly, issued several notices that provide various ways to strengthen the regulation of internet cafes, including investigating and punishinginternet cafes that accept minors, cracking down on internet cafes without sufficient and valid licenses, limiting the total number of internet cafes andapproving internet cafes within the planning made by relevant authorities, screening unlawful and adverse games and websites, and improving thecoordination of regulation over internet cafes and online games. Although currently most of our users access and consume our products and services fromtheir own devices, if internet cafes become one of the main venues for our users to access our website or online games, any reduction in the number, or anyslowdown in the growth, of internet cafes in China could limit our ability to maintain or increase our user base. In addition, the Chinese government has in recent years intensified its efforts to remove inappropriate content disseminated over the internet andwireless networks. In April 2014, the Chinese government initiated a campaign to enhance and enforce its scrutiny over internet content in China,particularly for pornographic content, and various websites were subject to penalties and in some cases outright suspension of website operations. In August2017, the CAC promulgated the Provisions on the Administration of Internet Comments Posting Services, and the Provisions on the Administration ofInternet Forum and Community Services, both of which require providers of relevant services to establish information review and inspection mechanism. Aswe implemented programs to comply with these regulations, we saw our subscriber numbers decline and may see more subscriber or user decline in the future.See “—Regulation and censorship of information disseminated over the internet in China, recently strengthened, have adversely affected our business andmay continue to adversely affect our business, and we may be liable for the digital media content on our platform.” Fluctuations in exchange rates may have a material adverse effect on your investment. Fluctuation in the value of the Renminbi may have a material adverse effect on the value of your investment. The value of the Renminbi against theU.S. dollar and other currencies may fluctuate and is affected by, among other things, changes in political and economic conditions. In July 2005, the PRCgovernment changed its decade-old policy of pegging the value of the Renminbi to the U.S. dollar, and the RMB appreciated more than 20% against the U.S.dollar over the following three years. Between July 2008 and June 2010, this appreciation halted and the exchange rate between the RMB and the U.S. dollarremained within a narrow band. Since June 2010, the RMB has fluctuated against the U.S. dollar, at times significantly and unpredictably. It is difficult topredict how market forces or PRC or U.S. government policy may impact the exchange rate between the RMB and the U.S. dollar in the future. Our financial statements are expressed in U.S. dollars, and most of our assets, costs and expenses are denominated in Renminbi. Substantially all ofour revenues were denominated in Renminbi. Significant revaluation of the RMB may have a material and adverse effect on your investment. For example, tothe extent that we need to convert U.S. dollars into RMB for our operations, appreciation of the RMB against the U.S. dollar would have an adverse effect onthe RMB amount we would receive from the conversion. Conversely, if we decide to convert our RMB into U.S. dollars for the purpose of making paymentsfor dividends on our ordinary shares or ADSs or for other business purposes, appreciation of the U.S. dollar against the RMB would have a negative effect onthe U.S. dollar amount available to us. In addition, appreciation or depreciation in the value of the RMB relative to U.S. dollars would affect our financialresults reported in U.S. dollar terms regardless of any underlying change in our business or results of operations. 36 Very limited hedging options are available in China to reduce our exposure to exchange rate fluctuations. To date, we have not entered into anyhedging transactions in an effort to reduce our exposure to foreign currency exchange risk. While we may decide to enter into hedging transactions in thefuture, the availability and effectiveness of these hedges may be limited and we may not be able to adequately hedge our exposure or at all. In addition, ourcurrency exchange losses may be magnified by PRC exchange control regulations that restrict our ability to convert RMB into foreign currency. Governmental control of currency conversion may limit our ability to utilize our revenues effectively and affect the value of your investment. The PRC government imposes controls on the convertibility of the Renminbi into foreign currencies and, in certain cases, the remittance of currencyout of China. We receive substantially all of our revenues in Renminbi. Under our current corporate structure, our Cayman Islands holding companyprimarily relies on dividend payments from our wholly-owned PRC subsidiaries, to fund any cash and financing requirements we may have. Under existingPRC foreign exchange regulations, payments of current account items, including profit distributions, interest payments and trade and service-related foreignexchange transactions, can be made in foreign currencies without prior SAFE approval by complying with certain procedural requirements. However,approval from or registration with appropriate government authorities is required where the Renminbi is to be converted into foreign currency and remittedout of China to pay capital expenses such as the repayment of loans denominated in foreign currencies. Specifically, under the existing exchange restrictions,without prior approval of SAFE, cash generated from the operations of our PRC subsidiaries in China may be used to pay dividends by our PRC subsidiariesto our company and pay employees of our PRC subsidiaries who are located outside China in a currency other than the Renminbi. With prior approval fromor registration with SAFE, cash generated from the operations of our PRC subsidiaries and affiliated entity may be used to pay off debt in a currency otherthan the Renminbi owed by our PRC subsidiaries and variable interest entity and its subsidiaries to entities outside China, and make other capitalexpenditures outside China in a currency other than the Renminbi. If any of our variable interest entity or its subsidiaries liquidates, the proceeds from theliquidation of its assets may be used outside of the PRC or be given to investors who are not PRC nationals. The PRC government may at its discretionrestrict access to foreign currencies for current account transactions in the future. If the foreign exchange control system prevents us from obtaining sufficientforeign currencies to satisfy our foreign currency demand, we may not be able to pay dividends in foreign currencies to our shareholders, including holders ofour ADSs. Certain regulations in the PRC may make it more difficult for us to pursue growth through acquisitions. Among other things, the M&A Rules and certain regulations and rules concerning mergers and acquisitions established additional procedures andrequirements that could make merger and acquisition activities by foreign investors more time-consuming and complex. For example, the M&A Rules requirethat the Ministry of Commerce be notified in advance of any change-of-control transaction in which a foreign investor takes control of a PRC domesticenterprise or a foreign company with substantial PRC operations, if certain thresholds under the Provisions on Thresholds for Prior Notification ofConcentrations of Undertakings, issued by the State Council on August 3, 2008, are triggered. Moreover, the Anti-Monopoly Law promulgated by theStanding Committee of the National People’s Congress on August 30, 2007 and took effect on August 1, 2008 requires that transactions which are deemedconcentrations and involve parties with specified turnover thresholds (i.e., during the previous fiscal year, (i) the total global turnover of all operatorsparticipating in the transaction exceeds RMB10 billion and at least two of these operators each had a turnover of more than RMB400 million within China,or (ii) the total turnover within China of all the operators participating in the concentration exceeded RMB2 billion, and at least two of these operators eachhad a turnover of more than RMB400 million within China) must be cleared by the Ministry of Commerce before they can be completed. In addition,according to the Implementing Rules Concerning Security Review on the Mergers and Acquisitions by Foreign Investors of Domestic Enterprises issued bythe Ministry of Commerce in August 2011, mergers and acquisitions by foreign investors involved in an industry related to national security are subject tostrict review by the Ministry of Commerce. These rules also prohibit any transactions attempting to bypass such security review, including by controllingentities through contractual arrangements. We believe that our business is not in an industry related to national security. However, we cannot preclude thepossibility that the Ministry of Commerce or other government agencies may publish interpretations contrary to our understanding or broaden the scope ofsuch security review in the future. Although we have no current definitive plans to make any acquisitions, we may elect to grow our business in the future inpart by directly acquiring complementary businesses in China. Complying with the requirements of these regulations to complete such transactions could betime-consuming, and any required approval processes, including obtaining approval from the Ministry of Commerce, may delay or inhibit our ability tocomplete such transactions. 37 PRC regulations relating to the establishment of offshore SPVs by PRC residents may subject our PRC resident beneficial owners or our PRC subsidiariesto liability or penalties, limit our ability to inject capital into our PRC subsidiaries, limit our PRC subsidiaries’ ability to increase their registered capitalor distribute profits to us, or may otherwise adversely affect us. SAFE has promulgated several regulations that require PRC residents and PRC corporate entities to register with local branches of SAFE inconnection with their direct or indirect offshore investment activities. These regulations apply to our shareholders who are PRC residents and may apply toany offshore acquisitions that we make in the future. SAFE promulgated the Circular on Relevant Issues Concerning Foreign Exchange Control on DomesticResidents’ Offshore Investment and Financing and Roundtrip Investment through Special Purpose Vehicles, or SAFE No. Circular No. 37, on July 4, 2014.SAFE Circular No. 37 requires PRC residents to register with local branches of SAFE in connection with their direct establishment or indirect control of anoffshore entity, for the purpose of overseas investment and financing, with such PRC residents’ legally owned assets or equity interests in domesticenterprises or offshore assets or interests, referred to in SAFE Circular No. 37 as a “special purpose vehicle.” The term “control” under SAFE Circular No. 37 isbroadly defined as the operation rights, beneficiary rights or decision-making rights acquired by the PRC residents in the offshore special purpose vehicles orPRC companies by such means as acquisition, trust, proxy, voting rights, repurchase, convertible bonds or other arrangements. SAFE Circular No. 37 furtherrequires amendment to the registration in the event of any changes with respect to the basic information of the special purpose vehicle, such as changes in aPRC resident individual shareholder, name or operation period; or any significant changes with respect to the special purpose vehicle, such as increase ordecrease of capital contributed by PRC individuals, share transfer or exchange, merger, division or other material event. If the shareholders of an offshoreholding company who are PRC residents do not complete their registration with the local SAFE branches, the PRC subsidiaries of the offshore holdingcompany may be prohibited from distributing their profits and proceeds from any reduction in capital, share transfer or liquidation to the offshore company,and the offshore company may be restricted in its ability to contribute additional capital to its PRC subsidiaries. Moreover, failure to comply with SAFEregistration and amendment requirements described above could result in liability under PRC law for evasion of applicable foreign exchange restrictions. Inaddition, on February 13, 2015, SAFE issued SAFE Circular No. 13, which took effect on June 1, 2015. SAFE Circular No. 13 delegates to the qualified banksthe authority to register all PRC residents’ investment in “special purpose vehicle” pursuant to SAFE Circular No. 37, except that those PRC residents whohave failed to comply with SAFE Circular No. 37 will continue to fall within the jurisdiction of the relevant local SAFE branches and must continue to maketheir supplementary registration applications with the such local SAFE branches. We have requested PRC residents holding direct or indirect interest in our company to our knowledge to make the necessary applications, filingsand amendments as required under SAFE regulations. Mr. Sean Shenglong Zou, Mr. Hao Cheng and Ms. Fang Wang have completed the registration andamendment registration with the local SAFE branch in relation to all our previous private financings and their subsequent ownership changes as requiredunder the SAFE regulations and Ms. Fang Wang is in the process of applying for the relevant amendment registrations with the local SAFE branch in relationto the ownership changes in her holding vehicle of our company. However, we may not be informed of the identities of all the PRC residents holding direct orindirect interest in our company, and we cannot provide any assurances that these PRC residents will comply with our request to make or obtain anyapplicable registrations or comply with other requirements required by SAFE regulations. The failure or inability of our PRC resident shareholders to makeany required registrations or comply with other requirements under SAFE regulations may subject such PRC residents or our PRC subsidiaries to fines andlegal sanctions and may also limit our ability to raise additional financing and contribute additional capital into or provide loans to (including using theproceeds from our initial public offering) our PRC subsidiaries, limit our PRC subsidiaries’ ability to pay dividends or otherwise distribute profits to us, orotherwise adversely affect us. Furthermore, because of the uncertainty over how the SAFE regulations will be interpreted and implemented, and how SAFE will apply them to us,we cannot predict how these regulations will affect our business operations or future strategies. For example, we may be subject to a more stringent reviewand approval process with respect to our foreign exchange activities, such as remittance of dividends and foreign-currency-denominated borrowings, whichmay adversely affect our financial condition and results of operations. In addition, if we decide to acquire a PRC domestic company, we cannot assure youthat we or the owners of such company, as the case may be, will be able to obtain the necessary approvals or complete the necessary filings and registrationsrequired by the foreign exchange regulations. This may restrict our ability to implement our acquisition strategy and could adversely affect our business andprospects. 38 Failure to comply with PRC regulations regarding the registration requirements for employee stock ownership plans or share option plans may subject thePRC plan participants or us to fines and other legal or administrative sanctions. In December 2006, the People’s Bank of China promulgated the Administrative Measures of Foreign Exchange Matters for Individuals, which setforth the respective requirements for foreign exchange transactions by individuals (both PRC or non-PRC citizens) under either the current account or thecapital account. On February 15, 2012, SAFE promulgated the Notices on Issues Concerning the Foreign Exchange Administration for Domestic IndividualsParticipating in Stock Incentive Plans of Overseas Publicly-Listed Companies, or the Stock Option Rules, which replaced the Application Procedures ofForeign Exchange Administration for Domestic Individuals Participating in Employee Stock Ownership Plans or Stock Option Plans of Overseas Publicly-Listed Companies issued by SAFE on March 28, 2007. Under the Stock Option Rules and other relevant rules and regulations, PRC residents who participatein stock incentive plan in an overseas publicly-listed company are required to register with SAFE or its local branches and complete certain other procedures.Participants of a stock incentive plan who are PRC residents must retain a qualified PRC agent, which could be a PRC subsidiary of such overseas publiclylisted company or another qualified institution selected by such PRC subsidiary, to conduct the SAFE registration and other procedures with respect to thestock incentive plan on behalf of its participants. Such participants must also retain an overseas entrusted institution to handle matters in connection withtheir exercise of stock options, the purchase and sale of corresponding stocks or interests and fund transfers. In addition, the PRC agent is required to amendthe SAFE registration with respect to the stock incentive plan if there is any material change to the stock incentive plan, the PRC agent or the overseasentrusted institution or other material changes. We and our PRC employees who have been granted stock options are subject to these regulations. Failure ofour PRC stock option holders to complete their SAFE registrations may subject these PRC residents to fines and legal sanctions and may also limit our abilityto contribute additional capital into our PRC subsidiaries, limit our PRC subsidiaries’ ability to distribute dividends to us, or otherwise materially adverselyaffect our business. We face uncertainties with respect to indirect transfers of equity interests in PRC resident enterprises by their non-PRC holding companies. The State Administration of Taxation, or the SAT, has issued several rules and notices to tighten its scrutiny over acquisition transactions in recentyears, including the Notice on Strengthening Administration of Enterprise Income Tax for Share Transfers by Non-PRC Resident Enterprises issued inDecember 2009, or SAT Circular 698, the Notice on Several Issues Regarding the Income Tax of Non-PRC Resident Enterprises issued in March 2011, orSAT Circular 24, and the Notice on Certain Corporate Income Tax Matters on Indirect Transfer of Properties by Non-PRC Resident Enterprises issued inFebruary 2015, or SAT Circular 7. Pursuant to these rules and notices, if a non-PRC resident enterprise indirectly transfers PRC taxable properties, which referto properties of an establishment or a place in the PRC, real estate properties in the PRC or equity investments in a PRC tax resident enterprise, by disposingof equity interest in an overseas non-public holding company without a reasonable commercial purpose and resulting in the avoidance of PRC enterpriseincome tax, such indirect transfer should be deemed a direct transfer of PRC taxable properties, and gains derived from such indirect transfer may be subjectto the PRC withholding tax at a rate of up to 10%. SAT Circular 7 sets out several factors to be taken into consideration by tax authorities in determiningwhether an indirect transfer has a reasonable commercial purpose. An indirect transfer satisfying all the following criteria will be deemed to lack reasonablecommercial purpose and be taxable under PRC law: (i) 75% or more of the equity value of the intermediary enterprise being transferred is derived directly orindirectly from the PRC taxable properties; (ii) at any time during the one-year period before the indirect transfer, 90% or more of the asset value of theintermediary enterprise (excluding cash) is comprised directly or indirectly of investments in the PRC, or 90% or more of its income is derived directly orindirectly from the PRC; (iii) the functions performed and risks assumed by the intermediary enterprise and any of its subsidiaries that directly or indirectlyhold the PRC taxable properties are limited and are insufficient to prove their economic substance; and (iv) the foreign tax payable on the gain derived fromthe indirect transfer of the PRC taxable properties is lower than the potential PRC enterprise income tax on the direct transfer of such assets. Nevertheless, theindirect transfer falling into the safe harbor available under SAT Circular 7 may not be subject to PRC tax and the scope of the safe harbor includes qualifiedgroup restructuring, public market trading and tax treaty exemptions. On October 17, 2017, the SAT issued the Public Notice on Issues Concerning theWithholding of Non-resident Enterprise Income Tax at Source, or SAT Public Notice 37, which took effect on December 1, 2017. SAT Public Notice 37replaced a series of important circulars, including but not limited to SAT Circular 698 and amended the rules governing the administration of withholdingtax on China-source income derived by the non-resident enterprise. SAT Public Notice 37 also introduced certain key changes to the current withholdingregime, such as (i) non-resident enterprise’s withholding obligation for dividend was changed to arise on the date the payment is actually made as opposed todividend declaration date; and (ii) non-resident enterprise’s obligation to self-report tax within seven days upon withholding agent’s failure to withhold wasremoved. 39 Under SAT Circular 7 and SAT Public Notice 37, the entities or individuals obligated to pay the transfer price to the transferor are the withholdingagents and must withhold the PRC enterprise income tax from the transfer price. If the withholding agent fails to do so, the transferor should report to and paythe PRC enterprise income tax to the PRC tax authorities. In the event that neither the withholding agent nor the transferor fulfills their obligations underSAT Circular 7 and SAT Public Notice 37, apart from imposing penalties such as late payment interest on the transferor, the tax authority may also hold thewithholding agent liable and impose a penalty of 50% to 300% of the unpaid tax on the withholding agent. The penalty imposed on the withholding agentmay be reduced or waived if the withholding agent has submitted the relevant materials in connection with the indirect transfer to the PRC tax authorities inaccordance with SAT Circular 7. However, there is a lack of clear statutory interpretation of these rules and notices, we face uncertainties on the reporting and consequences on futureprivate equity financing transactions, share exchange or other transactions involving the transfer of shares in our company by investors that are non-PRCresident enterprises, or sale or purchase of shares in other non-PRC resident companies or other taxable assets by us. Our Cayman Islands holding companyand other non-resident enterprises in our company may be subject to filing obligations or may be taxed if our Cayman Islands holding company and othernon-resident enterprises in our company are transferors in such transactions, and may be subject to withholding obligations if our Cayman Islands holdingcompany and other non-resident enterprises in our company are transferees in such transactions. For the transfer of shares in our Cayman Islands holdingcompany by investors that are non-PRC resident enterprises, our PRC subsidiaries may be requested to assist in the filing under the rules and notices. As aresult, we may be required to expend valuable resources to comply with these rules and notices or to request the relevant transferors from whom we purchasetaxable assets to comply, or to establish that our Cayman Islands holding company and other non-resident enterprises in our company should not be taxedunder these rules and notices, which may have a material adverse effect on our financial condition and results of operations. There is no assurance that the taxauthorities will not apply the rules and notices to our offshore restructuring transactions where non-PRC resident investors were involved if any of suchtransactions were determined by the tax authorities to lack reasonable commercial purpose. As a result, we and our non-PRC resident investors may be at riskof being taxed under these rules and notices and may be required to comply with or to establish that we should not be taxed under such rules and notices,which may have a material adverse effect on our financial condition and results of operations or such non-PRC resident investors’ investments in us. We haveconducted acquisition transactions in the past and may conduct additional acquisition transactions in the future. We cannot assure you that the PRC taxauthorities will not, at their discretion, adjust any capital gains and impose tax return filing obligations on us or require us to provide assistance for theinvestigation of PRC tax authorities with respect thereto. Heightened scrutiny over acquisition transactions by the PRC tax authorities may have a negativeimpact on potential acquisitions we may pursue in the future. Discontinuation or reduction of any of the preferential tax treatments or other government incentives available to us in the PRC, or imposition of anyadditional PRC taxes could adversely affect our financial condition and results of operations. The Chinese government has provided various tax incentives to our subsidiaries in China. These incentives include reduced enterprise income taxrates. For example, under the PRC Enterprise Income Tax Law which became effective in January 2008 and was amended in February 2017, or the EIT Law,the statutory enterprise income tax rate is 25%. The EIT Law permits companies established before March 16, 2007 to continue to enjoy their existing taxincentives, adjusted by certain transitional phase-out rules set forth in the Circular to Implementation of the Transitional Preferential Policies for theEnterprise Income Tax promulgated by the State Council on December 26, 2007, and provides tax incentives, subject to various qualification criteria.Pursuant to the circular, the income tax rates for us and our wholly-owned subsidiary established in the Shenzhen Special Economic Zone before March 16,2007 were 24% for 2011 and are 25% starting from 2012. The EIT Law and its implementation rules also permit qualified “high and new technologyenterprises,” or HNTEs, to enjoy a preferential enterprise income tax rate of 15% upon filing with relevant tax authorities. The qualification as a HNTEgenerally has a valid term of three years and the renewal of such qualification is subject to review by the relevant authorities in China. Shenzhen Xunlei, ourvariable interest entity, Shenzhen Wangwenhua, a subsidiary of Shenzhen Xunlei, and Shenzhen Onething currently hold a HNTE certificate and are entitledto enjoy a preferential enterprise income tax rate of 15% for the next three years ended August 2020 (for Shenzhen Xunlei and Shenzhen Wangwenhua) andOctober 2020 (for Shenzhen Onething). In addition, the PRC government has provided various incentives to accredited “software enterprise” incorporated inthe PRC in order to encourage development of the software industry. In December 2013, Shenzhen Xunlei obtained the certificate of the Key SoftwareEnterprise for the years ended December 31, 2013 and 2014, which enabled Shenzhen Xunlei to enjoy the preferential tax rate of 10% for the years of 2013and 2014. In September 2014, Shenzhen Xunlei renewed the certificate of the Hi-Tech Enterprise for the years ended December 31, 2015, 2016 and 2017,which enables Shenzhen Xunlei to enjoy the preferential tax rate of 15% for the years of 2015, 2016 and 2017. Xunlei Computer has been accredited as a“software enterprise” and become profitable since 2013 and thus enjoys a two-year income tax exemption for 2013 and 2014 and a 50% income taxreduction for 2015, 2016 and 2017. Moreover, local governments have adopted incentives to encourage the development of technology companies.Shenzhen Xunlei, Shenzhen Onething, Shenzhen Wangwenhua and Xunlei Computer currently benefit from the tax incentives. See “Item 5. Operating andFinancial Overview and Prospects—A. Operating Results—Taxation.” 40 Preferential tax treatment and other government incentives granted to Xunlei Computer and Shenzhen Xunlei by the local governmental authoritiesare subject to review and may be adjusted or revoked at any time. The discontinuation or reduction of any preferential tax treatment currently available to usand our wholly-owned PRC subsidiaries will cause our effective tax rate to increase, which could have a material adverse effect on our financial conditionand results of operations. We cannot assure you that we will be able to maintain our current effective tax rate in the future. Our global income may be subject to PRC taxes under the PRC EIT Law, which may have a material adverse effect on our results of operations. Under the EIT Law and its implementation rules, an enterprise established outside of the PRC with a “de facto management body” within the PRC isconsidered a resident enterprise and will be subject to the enterprise income tax at the rate of 25% on its global income. The implementation rules define theterm “de facto management bodies” as “establishments that carry out substantial and overall management and control over the manufacturing and businessoperations, personnel, accounting, properties, etc. of an enterprise.” On April 22, 2009, the SAT issued a circular, or SAT Circular 82, which provides certainspecific criteria for determining whether the “de facto management body” of a PRC-controlled enterprise that is incorporated offshore is located in China. See“Item 4. Information on the Company—B. Business Overview—Regulation—Regulations on Tax—PRC enterprise income tax.” Although SAT Circular 82applies only to offshore enterprises controlled by PRC enterprises or PRC enterprise groups and not to those controlled by PRC individuals or foreigners, thedetermining criteria set forth in the SAT Circular 82 may reflect the SAT’s general position on how the “de facto management body” test should be applied indetermining the tax resident status of all offshore enterprises. According to SAT Circular 82, an offshore incorporated enterprise controlled by a PRC enterprise or a PRC enterprise group will be regarded as aPRC tax resident by virtue of having its “de facto management body” in China and will be subject to PRC enterprise income tax on its worldwide incomeonly if all of the following conditions set forth in the SAT Circular 82 are met: (i) the primary location of the day-to-day operational management is in thePRC; (ii) decisions relating to the enterprise’s financial and human resource matters are made or are subject to approval by organizations or personnel in thePRC; (iii) the enterprise’s primary assets, accounting books and records, company seals, and board and shareholder resolutions are located or maintained inthe PRC; and (iv) at least 50% of voting board members or senior executives habitually reside in the PRC. Xunlei Limited is not controlled by a PRC enterprise or PRC enterprise group and we do not believe that Xunlei Limited meets all of the conditionsabove. Xunlei Limited is a company incorporated outside the PRC. As a holding company, certain of Xunlei Limited’s key assets are located, and records(including the resolutions of its board of directors and the resolutions of its shareholders) are maintained, outside the PRC. Therefore, we do not believeXunlei Limited should be treated as a “resident enterprise” for PRC tax purposes if the criteria for “de facto management body” as set forth in the relevantSAT Circular 82 were deemed applicable to us. However, as the tax resident status of an enterprise is subject to determination by the PRC tax authorities anduncertainties remain with respect to the interpretation of the term “de facto management body” as applicable to Xunlei Limited, we may be considered aresident enterprise and may therefore be subject to the enterprise income tax at 25% on our global income. If we are considered a resident enterprise and earnincome other than dividends from our PRC subsidiaries, a 25% enterprise income tax on our global income could increase our tax burden and adverselyaffect our cash flow and profitability. In addition to the uncertainty regarding how the new “resident enterprise” classification may apply, it is also possiblethat the rules may change in the future, possibly with retroactive effect. 41 Dividends paid by us to our foreign investors and gains on the sale of our ADSs or common shares by our foreign investors may be subject to taxes underPRC tax laws. Under the EIT Law and its implementation regulations issued by the State Council, a 10% PRC withholding tax is applicable to dividends paid toinvestors that are “non-resident enterprises,” which do not have an establishment or place of business in the PRC or which have such establishment or placeof business but the dividends are not effectively connected with such establishment or place of business, to the extent such dividends are derived fromsources within the PRC. Any gain realized on the transfer of ADSs or common shares by such investors is subject to PRC tax, at a rate of 10% unless otherwisereduced or exempted by relevant tax treaties, if such gain is regarded as income derived from sources within the PRC. If we are deemed a “PRC residententerprise,” dividends paid on our common shares or ADSs, and any gain realized from the transfer of our common shares or ADSs, may be treated as incomederived from sources within the PRC and may as a result be subject to PRC taxation (which in the case of dividends would be withheld at source). It is unclearwhether our non-PRC individual investors would be subject to any PRC tax in the event we are deemed a “PRC resident enterprise.” If any PRC tax were toapply to such dividends or gains of non-PRC individual investors, it would generally apply at a rate of 20% (unless a reduced rate is available under anapplicable tax treaty). It is also unclear whether, if we are considered a PRC “resident enterprise,” holders of our ADSs or common shares would be able toclaim the benefit of income tax treaties or agreements entered into between China and other countries or areas (and we do not expect to withhold at treatyrates if any withholding is required). If dividends payable to our non-PRC investors, or gains from the transfer of our common shares or ADSs by suchinvestors are subject to PRC tax, the value of your investment in our common shares or ADSs may be adversely affected. Increases in labor costs and enforcement of stricter labor laws and regulations in the PRC may adversely affect our business and our profitability. China’s overall economy and the average wage in China have increased in recent years and are expected to continue to grow. The average wagelevel for our employees has also increased in recent years. We expect that our labor costs, including wages and employee benefits, will continue to increase.Unless we are able to pass on these increased labor costs to our users by increasing prices for our products or services, our profitability and results ofoperations may be materially and adversely affected. In addition, we have been subject to stricter regulatory requirements in terms of entering labor contracts with our employees and paying variousstatutory employee benefits, including pensions, housing fund, medical insurance, work-related injury insurance, unemployment insurance and childbearinginsurance to designated government agencies for the benefit of our employees. Pursuant to the PRC Labor Contract Law, or the Labor Contract law, thatbecame effective in January 2008, as amended on December 28, 2012 and effective as of July 1, 2013, and its implementation rules that became effective inSeptember 2008, employers are subject to stricter requirements in terms of signing labor contracts, minimum wages, paying remuneration, determining theterm of employees’ probation and unilaterally terminating labor contracts. In the event that we decide to terminate some of our employees or otherwisechange our employment or labor practices, the Labor Contract Law and its implementation rules may limit our ability to effect those changes in a desirable orcost-effective manner, which could adversely affect our business and results of operations. On October 28, 2010, the Standing Committee of the NationalPeople’s Congress promulgated the PRC Social Insurance Law, or the Social Insurance Law, which became effective on July 1, 2011. According to the SocialInsurance Law, employees must participate in pension insurance, work-related injury insurance, medical insurance, unemployment insurance and maternityinsurance and the employers must, together with their employees or separately, pay the social insurance premiums for such employees. As the interpretation and implementation of labor-related laws and regulations are still evolving, we cannot assure you that our employment practicedo not and will not violate labor-related laws and regulations in China, which may subject us to labor disputes or government investigations. If we aredeemed to have violated relevant labor laws and regulations, we could be required to provide additional compensation to our employees and our business,financial condition and results of operations could be materially and adversely affected. 42 The audit report included in this annual report is prepared by an auditor who is not inspected by the Public Company Accounting Oversight Board and, assuch, you are deprived of the benefits of such inspection. Auditors of companies that are registered with the Securities and Exchange Commission, or the SEC, and traded publicly in the United States,including our independent registered public accounting firm, must be registered with the Public Company Accounting Oversight Board, or the PCAOB, andare required by the laws of the United States to undergo regular inspections by PCAOB to assess their compliance with the laws of the United States andprofessional standards. Because we have substantiated operations within the Peoples’ Republic of China and the PCAOB is currently unable to conductinspections of the work of our auditors as it relates to those operations without the approval of the Chinese authorities, our auditor’s work related to ouroperations in China is not currently inspected by the PCAOB. This lack of PCAOB inspections of audit work performed in China prevents the PCAOB from regularly evaluating audit work of any auditors thatwas performed in China including that performed by our independent registered public accounting firm. As a result, investors may be deprived of the fullbenefits of PCAOB inspections. The inability of the PCAOB to conduct inspections of audit work performed in China makes it more difficult to evaluate the effectiveness of ourauditor’s audit procedures as compared to auditors in other jurisdictions that are subject to PCAOB inspections on all of their work. Investors may loseconfidence in our reported financial information and procedures and the quality of our financial statements. If additional remedial measures are imposed on certain PRC-based accounting firms in administrative proceedings brought by the SEC, we could beunable to file future financial statements on a timely basis in compliance with the requirements of the Exchange Act. In December 2012, the SEC instituted administrative proceedings against certain PRC-based accounting firms, including our independent registeredpublic accounting firm, alleging that these firms had violated U.S. securities laws and the SEC’s rules and regulations thereunder by failing to provide to theSEC the firms’ work papers related to their audits of certain PRC-based companies that are publicly traded in the United States. On January 22, 2014, aninitial administrative law decision was issued, sanctioning these accounting firms and suspending them from practicing before the SEC for a period of sixmonths. On February 12, 2014, four of these PRC-based accounting firms appealed to the SEC against this sanction. In February 2015, each of the four PRC-based accounting firms agreed to a censure and to pay a fine to the SEC to settle the dispute and avoid suspension of their ability to practice before the SEC.The settlement requires the firms to follow detailed procedures to seek to provide the SEC with access to Chinese firms’ audit documents via the CSRC. If thefirms do not follow these procedures or if there is a failure in the process between the SEC and the CSRC, the SEC could impose penalties such assuspensions, or it could restart the administrative proceedings. In the event that the SEC restarts the administrative proceedings, depending upon the final outcome, listed companies in the United States withmajor PRC operations may find it difficult or impossible to retain auditors in respect of their operations in the PRC, which could result in financial statementsbeing determined to not be in compliance with the requirements of the Exchange Act, including possible delisting. Moreover, any negative news about theproceedings against these audit firms may cause investor uncertainty regarding China-based, United States-listed companies and the market price of ourADSs may be adversely affected. If our independent registered public accounting firm were denied, even temporarily, the ability to practice before the SEC and we were unable totimely find another registered public accounting firm to audit and issue an opinion on our financial statements, our financial statements could be determinedto not be in compliance with the requirements for financial statements of public companies registered under the Exchange Act, as amended, or the ExchangeAct. Such a determination could ultimately lead to the delisting of our common stock from the NASDAQ Global Select Market or deregistration from theSEC, which would substantially reduce or effectively terminate the trading of our common stock in the United States. 43 Risks related to our ADSs The market price for our ADSs may be volatile. The trading prices of our ADSs are likely to be volatile and could fluctuate widely due to factors beyond our control. This may happen because ofbroad market and industry factors, like the performance and fluctuation in the market prices or the underperformance or deteriorating financial results of othersimilarly situated companies in China that have listed their securities in the United States in recent years. The securities of some of these companies haveexperienced significant volatility since their initial public offerings, including, in some cases, substantial price declines in the trading prices of theirsecurities. The trading performances of these Chinese companies’ securities after their offerings, including companies in the internet businesses, may affectthe attitudes of investors toward Chinese companies listed in the United States, which consequently may impact the trading performance of our ADSs,regardless of our actual operating performance. In addition, any negative news or perceptions about inadequate corporate governance practices or fraudulentaccounting or other practices at other Chinese companies may also negatively affect the attitudes of investors towards Chinese companies in general,including us, regardless of whether we have engaged in such practices. In addition, securities markets may from time to time experience significant price andvolume fluctuations that are not related to our operating performance, which may have a material adverse effect on the market price of our ADSs. The market price for our ADSs is likely to be highly volatile and subject to wide fluctuations in response to factors including the following: ·regulatory developments affecting us, our advertisers or our industry; ·announcements of studies and reports relating to our services or those of our competitors; ·changes in the economic performance or market valuations of other internet companies in China; ·actual or anticipated fluctuations in our quarterly results of operations and changes of our expected results; ·changes in financial estimates by securities research analysts; ·conditions in the internet or online advertising industry in China; ·announcements by us or our competitors of new services, acquisitions, strategic relationships, joint ventures or capital commitments; ·additions to or departures of our senior management; ·fluctuations of exchange rates between the Renminbi and the U.S. dollar; ·release or expiry of lock-up or other transfer restrictions on our outstanding shares or ADSs; and ·sales or perceived potential sales of additional shares or ADSs. In addition, the securities market has from time to time experienced significant price and volume fluctuations that are not related to the operatingperformance of any particular companies. These market fluctuations may also have a material adverse effect on the market price of our ADSs. If securities or industry analysts cease to publish research or reports about our business, or if they adversely change their recommendations regarding ourADSs, the market price for our ADSs and trading volume could decline. The trading market for our ADSs will be influenced by research or reports that industry or securities analysts publish about our business. If one ormore analysts who cover us downgrade our ADSs, the market price for our ADSs would likely decline. If one or more of these analysts cease to cover us or failto regularly publish reports on us, we could lose visibility in the financial markets, which, in turn, could cause the market price or trading volume for ourADSs to decline. 44 As we do not expect to pay dividends in the foreseeable future, you must rely on price appreciation of our ADSs for return on your investment. We currently intend to retain most, if not all, of our available funds and any future earnings to fund the development and growth of our business.Subject to our ongoing financial performance, cash position, budget and business plan and market conditions, we may consider paying special dividends.However, we do not plan to pay dividends in the foreseeable future and you should not rely on an investment in our ADSs as a source for any future dividendincome. Our board of directors has discretion as to whether to distribute dividends, subject to applicable laws. Our shareholders may by ordinary resolutiondeclare dividends, but no dividend may exceed the amount recommended by our board of directors. Under Cayman Islands law, a Cayman Islands companymay pay a dividend out of either profit or share premium account, provided that in no circumstances may a dividend be paid if this would result in thecompany being unable to pay its debts as they fall due in the ordinary course of business. Even if our board of directors decides to declare and pay dividends,the timing, amount and form of future dividends, if any, will depend on, among other things, our future results of operations and cash flow, our capitalrequirements and surplus, the amount of distributions, if any, received by us from our subsidiaries, our financial condition, contractual restrictions and otherfactors deemed relevant by our board of directors. Accordingly, the return on your investment in our ADSs will likely depend entirely upon any future priceappreciation of our ADSs. There is no guarantee that our ADSs will appreciate in value or even maintain the price at which you purchased the ADSs. You maynot realize a return on your investment in our ADSs and you may even lose your entire investment in our ADSs. Substantial future sales or perceived potential sales of our ADSs in the public market could cause the price of our ADSs to decline. Sales of our ADSs in the public market, or the perception that these sales could occur, could cause the market price of our ADSs to decline. As ofMarch 31, 2018, we had 334,430,280 common shares outstanding, which excludes (i) 9,519,144 common shares issued to Leading Advice Holdings Limitedfor grants under our 2013 Plan and 2014 Plan that remained then unexercised or unvested, and (ii) 24,927,785 common shares, consisting of shares issued toour depositary bank for bulk issuance of ADSs reserved for future issuances upon the exercise or vesting of awards granted under our share incentive plansand shares repurchased by the company from 2015 to 2017 but not yet cancelled. All our outstanding common shares represented by ADSs were freelytransferable by persons other than our “affiliates” without restriction or additional registration under the Securities Act of 1933, as amended, or Securities Act.The remaining common shares will be available for sale subject to volume and other restrictions as applicable under Rules 144 and 701 under the SecuritiesAct. Certain holders of our common shares have the right to cause us to register under the Securities Act the sale of their shares. Registration of these sharesunder the Securities Act would result in ADSs representing these shares becoming freely tradable without restriction under the Securities Act immediatelyupon the effectiveness of the registration. Sales of these registered shares in the form of ADSs, in the public market could cause the price of our ADSs todecline. Your right to participate in any future rights offerings may be limited, which may cause dilution to your holdings, and you may not receive cash dividendsif it is impractical to make them available to you. We may from time to time distribute rights to our shareholders, including rights to acquire our securities. However, we cannot make rights availableto you in the United States unless we register both the rights and the securities to which the rights relate under the Securities Act or an exemption from theregistration requirements is available. Under the deposit agreement, the depositary will not make rights available to you unless both the rights and theunderlying securities to be distributed to ADS holders are either registered under the Securities Act or exempt from registration under the Securities Act. Weare under no obligation to file a registration statement with respect to any such rights or securities or to endeavor to cause such a registration statement to bedeclared effective and we may not be able to establish a necessary exemption from registration under the Securities Act. Accordingly, you may be unable toparticipate in our rights offerings and may experience dilution in your holdings. The depositary of our ADSs has agreed to pay to you the cash dividends or other distributions it or the custodian receives on our common shares orother deposited securities after deducting its fees and expenses. You will receive these distributions in proportion to the number of common shares your ADSsrepresent. However, the depositary may, at its discretion, decide that it is inequitable or impractical to make a distribution available to any holders of ADSs.For example, the depositary may determine that it is not practicable to distribute certain property through the mail, or that the value of certain distributionsmay be less than the cost of mailing them. In these cases, the depositary may decide not to distribute such property to you. 45 You may be subject to limitations on transfer of your ADSs. Your ADSs are transferable on the books of the depositary. However, the depositary may close its transfer books at any time or from time to timewhen it deems expedient in connection with the performance of its duties. In addition, the depositary may refuse to deliver, transfer or register transfers ofADSs generally when our books or the books of the depositary are closed, or at any time if we or the depositary deems it advisable to do so because of anyrequirement of law or of any government or governmental body, or under any provision of the deposit agreement, or for any other reason. You may face difficulties in protecting your interests, and your ability to protect your rights through the U.S. federal courts may be limited because we areincorporated under Cayman Islands law, we conduct substantially all of our operations in China and substantially all of our directors and officers resideoutside the United States. We are incorporated in the Cayman Islands and conduct substantially all of our operations in China through our PRC subsidiaries and variableinterest entity and its subsidiaries. Substantially all of our directors and officers reside outside the United States. As a result, it may be difficult or impossiblefor you to bring an action against us or against these individuals in the Cayman Islands or in the United States in the event that you believe that your rightshave been infringed under the U.S. securities laws or otherwise. Even if you are successful in bringing an action of this kind, the laws of the Cayman Islandsand of China may render you unable to enforce a judgment against our assets or the assets of our directors and officers. There are uncertainties as to whether Cayman Islands courts would: ·recognize or enforce against us judgments of courts of the United States based on certain civil liability provisions of U.S. securities laws; and ·impose liabilities against us, in original actions brought in the Cayman Islands, based on certain civil liability provisions of U.S. securities lawsthat are penal in nature. There is no statutory recognition in the Cayman Islands of judgments obtained in the United States, although the courts of the Cayman Islands willin certain circumstances recognize and enforce a non-penal judgment of a foreign court of competent jurisdiction without retrial on the merits. Our corporate affairs are governed by our memorandum and articles of association, as amended and restated from time to time, and by the CompaniesLaw (2016 Revision) and common law of the Cayman Islands. The rights of shareholders to take legal action against us and our directors, actions by minorityshareholders and the fiduciary duties of our directors to us under Cayman Islands law are to a large extent governed by the common law of the CaymanIslands. The common law of the Cayman Islands is derived in part from comparatively limited judicial precedent in the Cayman Islands as well as fromEnglish common law, which provides persuasive, but not binding, authority in a court in the Cayman Islands. The rights of our shareholders and the fiduciaryduties of our directors under Cayman Islands law are not as clearly established as they would be under statutes or judicial precedents in the United States. Inparticular, the Cayman Islands has a less developed body of securities laws than the United States and provides significantly less protection to investors. Inaddition, shareholders in Cayman Islands companies may not have standing to initiate a shareholder derivative action in U.S. federal courts. As a result, our public shareholders may have more difficulty in protecting their interests through actions against us, our management, our directorsor our controlling shareholders than would shareholders of a corporation incorporated in a jurisdiction in the United States. We are an emerging growth company within the meaning of the Securities Act and may take advantage of certain reduced reporting requirements. We are an “emerging growth company,” as defined in the JOBS Act, and we may take advantage of certain exemptions from various requirementsapplicable to other public companies that are not emerging growth companies including, most significantly, not being required to comply with the auditorattestation requirements of Section 404 for so long as we are an emerging growth company. We have elected not to voluntarily comply with such auditorattestation requirements. Therefore, our investors may not have access to certain information they may deem important. 46 The JOBS Act also provides that an emerging growth company does not need to comply with any new or revised financial accounting standardsuntil such date that a private company is otherwise required to comply with such new or revised accounting standards. However, we have elected to “opt out”of this provision and, as a result, we will comply with new or revised accounting standards as required when they are adopted for public companies. Thisdecision to opt out of the extended transition period under the JOBS Act is irrevocable. Our memorandum and articles of association contains anti-takeover provisions that could adversely affect the rights of holders of our common shares andADSs. Our currently effective memorandum and articles of association contains certain provisions that could limit the ability of others to acquire control ofour company, including a provision that grants authority to our board directors to establish from time to time one or more series of preferred shares withoutaction by our shareholders and to determine, with respect to any series of preferred shares, the terms and rights of that series. The provisions could have theeffect of depriving our shareholders of the opportunity to sell their shares at a premium over the prevailing market price by discouraging third parties fromseeking to obtain control of our company in a tender offer or similar transactions. Our corporate actions are substantially controlled by our directors, executive officers and other principal shareholders, who can exert significantinfluence over important corporate matters, which may reduce the price of our ADSs and deprive you of an opportunity to receive a premium for yourshares. As of March 31, 2018, our directors, executive officers and existing principal shareholders beneficially owned approximately 54.49% of ouroutstanding common shares. These shareholders, if acting together, could exert substantial influence over matters such as electing directors and approvingmaterial mergers, acquisitions or other business combination transactions. This concentration of ownership may also discourage, delay or prevent a change incontrol of our company, which could have the dual effect of depriving our shareholders of an opportunity to receive a premium for their shares as part of asale of our company and reducing the price of our ADSs. These actions may be taken even if they are opposed by our other shareholders. In addition, thesepersons could divert business opportunities away from us to themselves or others. We incur increased costs as a result of being a public company, particularly after we cease to qualify as an “emerging growth company.” As a public company in the United States, we incur significant accounting, legal and other expenses that we did not incur as a private company. TheSarbanes-Oxley Act, as well as rules subsequently implemented by the Securities and Exchange Commission and the NASDAQ Global Select Market, requiresignificantly heightened corporate governance practices of public companies, including Section 404 relating to internal control over financial reporting. Wequalify as an “emerging growth company” pursuant to the JOBS Act. An emerging growth company may take advantage of specified reduced reporting andother requirements that are otherwise applicable generally to public companies. These provisions include exemption from the auditor attestation requirementunder Section 404 of the Sarbanes-Oxley Act of 2002 in the assessment of the emerging growth company’s internal control over financial reporting andpermission to delay adopting new or revised accounting standards until such time as those standards apply to private companies. However, we have electedto “opt out” of this provision and, as a result, we will comply with new or revised accounting standards as required when they are adopted for publiccompanies. This decision to opt out of the extended transition period under the JOBS Act is irrevocable. We expect these and other rules and regulations applicable to public companies will increase our accounting, legal and financial compliance costsand will make certain corporate activities more time-consuming and costly. After we are no longer an “emerging growth company,” we expect to incursignificant expenses and devote substantial management effort toward ensuring compliance with the requirements of Section 404 of the Sarbanes-Oxley Actof 2002 and the other rules and regulations of the SEC. Compliance with these rules and requirements may be especially difficult and costly for us becausewe may have difficulty locating sufficient personnel in China with experience and expertise relating to U.S. GAAP and U.S. public company reportingrequirements, and such personnel may command high salaries relative to similarly experienced personnel in the United States. If we cannot employ sufficientpersonnel to ensure compliance with these rules and regulations, we may need to rely more on outside legal, accounting and financial experts, which may becostly. If we fail to comply with these rules and requirements, or are perceived to have weaknesses with respect to our compliance, we could become thesubject of a governmental enforcement action and investor confidence could be negatively impacted and the market price of our ADSs could decline. Inaddition, we will incur additional costs associated with our public company reporting requirements. We are currently evaluating and monitoringdevelopments with respect to these rules and regulations, and we cannot predict or estimate with reasonable certainty the amount of additional costs we mayincur or the timing of such costs. 47 We believe we were a passive foreign investment company for our taxable year ended December 31, 2017, which could subject United States investors inthe ADSs or common shares to significant adverse United States income tax consequences. Based on the market price of our ADSs and the composition of our assets (in particular the retention of a substantial amount of cash), we believe thatwe were a “passive foreign investment company,” (or a “PFIC”), for United States federal income tax purposes for our taxable year ended December 31, 2017,and we will very likely be a PFIC for our current taxable year ending December 31, 2018 unless the market price of our ADSs increases and/or we invest asubstantial amount of the cash and other passive assets we hold in assets that produce or are held for the production of active income. In addition, it ispossible that one or more of our subsidiaries may be or become classified as a PFIC for United States federal income tax purposes. A non-U.S. corporation willbe classified as a PFIC for any taxable year if either (1) 75% or more of its gross income consists of certain types of passive income or (2) 50% or more of theaverage quarterly value of its assets (as generally determined on that basis of fair market value) during such year produce or are held for the production ofpassive income. If we are classified as a PFIC for any taxable year during which a U.S. Holder (as defined in Item 10. Additional Information—E. Taxation—UnitedStates Federal Income Tax Considerations) holds our ADSs or common shares, such U.S. Holder may incur significantly increased United States income taxon gain recognized on the sale or other disposition of the ADSs or common shares and on the receipt of distributions on the ADSs or common shares to theextent such gain or distribution is treated as an “excess distribution” under the United States federal income tax rules. Further, if we are classified as a PFICfor any year during which a U.S. Holder holds our ADSs or common shares, we generally will continue to be treated as a PFIC for all succeeding years duringwhich such U.S. Holder holds our ADSs or common shares (“PFIC Tainted Shares”) even if, we, in fact, cease to be a PFIC in subsequent taxable years.Accordingly, a U.S. Holder of our ADSs or common shares is urged to consult its tax advisor concerning the United States federal income tax considerationsrelated to holding and disposing of ADSs or common shares (including, to the extent an election is available, making a “mark-to-market” election to avoidowning PFIC-Tainted Shares and the unavailability of an election to treat us as a qualified electing fund). For more information see the section titled “Item10. Additional Information—E. Taxation—United States Federal Income Tax Considerations—Passive Foreign Investment Company Considerations.” Item 4.Information on the Company A.History and Development of the Company We commenced operations in January 2003 through the establishment of Shenzhen Xunlei, which currently, together with its various subsidiaries inthe PRC, operates our Xunlei internet platform.

We operate a powerful internet platform in China based on cloudtechnology to enable our users to quickly access, manage, and consume digital media content on the internet. In recent years, we have expanded our productsand services from PC-based devices to mobile devices in part through pre-installed acceleration products in mobile phones to further enlarge our user baseand offer our users a wider range of access points. We target to deliver superior user experience in terms of ease of access, management and consumption ofdigital media content anywhere, anytime, and on any device. To address deficiencies of digital media transmission over the internet in China, such as low speed and high delivery failure rates, we provide userswith quick and easy access to online digital media content through core products and services below: ·Xunlei Accelerator, our most popular and free product, which enables users to accelerate digital transmission over the internet and hasapproximately 145 million monthly unique visitors in December 2017, according to our internal record; and ·Cloud acceleration subscription services, which are delivered through products such as Green Channel and Offline Accelerator and offer userspremium services for speed and reliability. Benefitting from the large user base of our core product, Xunlei Accelerator, we have further developed various value-added services or products tomeet a fuller spectrum of our users’ digital media content access and consumption needs. These value-added services and products primarily include (i) cloudcomputing services, (ii) live video services, and (iii) online game services. We are increasingly extending our services to mobile devices, as part of our cloud-based mobile strategies. Mobile Xunlei is becoming a popularmobile application, while bigger screen phones with enhanced storage capacity have influenced user behavior in how they access and consume digital mediacontent on their mobile phones. This mobile application allows users to search, download and consume digital media content on their mobile devices in auser friendly way. Based on our own record, daily active user of this application was about 6.9 million as of the date of this annual report. Mobile Xunlei isalso one of the most downloaded applications in its category. In the fourth quarter of 2015, we started to monetize our mobile traffic through advertising salesand generated our first mobile advertising revenues. Moreover, this mobile application supplements our existing subscriptions business, enabling us to reacha wider set of user base and to expand our services additional devices of a user who has multiple devices. Our mobile initiatives also benefits from our relationship with Xiaomi, one of our strategic shareholders. Since 2014, we have entered into a pre-installing services agreement with a Xiaomi group company which manufactures Xiaomi phones, a well-recognized brand of smart phones in China. Pursuantto the agreement, we agree to provide our Mobile Xunlei acceleration plug-in, and the mobile phone manufacturer agrees to install such plug-in on itsphones, free of charge. Such pre-installment arrangement provides mobile phone users with access to our acceleration services, which we believe enhancesour ability to generate more user traffic. Our mobile acceleration software has been officially adopted by Xiaomi’s operating systems, MIUI6, MIUI7, MIUI8and MIUI9 and the software has been installed on Xiaomi phones, including both new phones shipments and system upgrades from existing Xiaomi phones. An important part of our strategies is to continue our innovation in crowdsourcing for idle capacity and potentially storage from users of our cloudcomputing services, which targets to utilize our users’ idle uplink capacity and storage by using our hardware devices. We plan for crowdsourced capacity tosupply an increasing percentage of the bandwidth that we use for our own acceleration services. From the third quarter of 2015, we started to sellcrowdsourced uplink capacity we collected from users under our cloud computing services to third parties. We intend to sell crowdsourced uplink capacity tomore third party internet content providers with bandwidth demand. To further develop our cloud computing business and at the same time explore emergingblockchain technology, we launched our decentralized cloud computing product, OneThing Cloud, and its related LinkToken, which is renamed fromOneCoin, a type of digital tickets based on blockchain technology, in 2017. OneThing Cloud is essentially a cloud-based storage and sharing device. Itallows users to share their idle internet bandwidth and storage resources with our content delivery networks. By voluntarily participating in our OneThingReward Program, users can be rewarded with LinkToken, which can be used to redeem for our products and services. The technological backbone of ourproducts and services is our cloud acceleration technology, comprised of a proprietary file locating system and massive file index database. Our technologyenables us to support greater user expansion with incremental increases in server and bandwidth costs. This technology, based on distributed computingarchitecture, along with our indexing technology, enables users to access content in an efficient manner. 50 We generated revenues by monetizing our large user base, primarily through the following services: ·Cloud acceleration subscription services. We provide premium acceleration services to subscribers to enable faster and more reliable access todigital media content; ·Online advertising services (including mobile advertising). We offer advertising services by providing marketing opportunities on our websites,mobile Xunlei application and platform to our advertisers; ·Sales of our cloud computing devices. OneThing Cloud is a hardware device that provides our users with easy access to our cloud computingservices. We generate a portion of our revenue from selling OneThing Cloud device to our users; and ·Other internet value-added services. We offer multiple other value-added services to our users including our cloud computing services, livevideo services and online game services. Our revenues increased from US$104.8 million in 2015 to US$141.0 million in 2016 and further to US$201.9 million in 2017. We had a net lossattributable to Xunlei Limited of US$13.2 million in 2015, US$24.1 million in 2016 and US$37.8 million in 2017. Our platform On our platform, users can accelerate digital media transmission and play a broad range of the latest online games, among other things. Cloud based acceleration We provide data transmission acceleration services based on cloud computing technology to internet users. Our cloud computing technologyutilizes a network of computers hosted on the internet to store, manage, and process data, thus providing our users with acceleration in internet datatransmission and improves their download success rates. We provide our acceleration services to internet users with the following products and services. Accelerator We launched our core product, Xunlei Accelerator, in 2004 to address deficiencies of digital media content transmission over internet in China, suchas low speed and high delivery failure rates. Xunlei Accelerator allows users to accelerate digital transmission over the internet for free. Xunlei Acceleratoralso bridges users with diverse needs to other services we offer, such as: Xunlei Media Player, which supports both online and offline video watching, and ourvarious online games, by recommending and providing links to these services on its user interface. Xunlei Accelerator is designed to provide an effective digital media content transmission solution to our users. In addition to our featuredtransmission acceleration function, we have integrated certain features into the interface of Xunlei Accelerator to enhance the overall user experience whilehelping users transmit their desired content efficiently. For example, Xunlei Accelerator provides a platform to integrate other third-party plug-inapplications. Users can add application tabs to create shortcuts to various services that are provided by us, third-party application developers and applicationvenders who have business relationships with us. Xunlei Accelerator also has a task management console to allow users to track and manage theirtransmissions in progress, to manage and prioritize cloud-based data transmission tasks, or manage and synchronize transmitted content across multipleinternet-enabled devices. 51 Mobile acceleration plug-in We offer a mobile acceleration plug-in, which provides mobile device users with benefits of download speed acceleration and download success rateimprovements similar to those offered by the PC-based Xunlei Accelerator. Our mobile acceleration plug-in has been adopted by Xiaomi, a Chinesesmartphone maker, on its operating systems, MIUI6, MIUI7, MIUI8 and MIUI9. Xiaomi installs our mobile acceleration plug-in on all of its new phones freeof charge and adds such plug-in to the existing ones via system upgrade. Xiaomi phone users thus have access to our acceleration services. Subscription services We charge monthly or annual fees for our premium cloud acceleration subscription services. The benefits and services within the subscriptionpackage, which typically include incrementally larger bandwidth and faster acceleration speed, are upgraded according to the VIP levels. The subscriptionfees generally remain unchanged for subscribers at higher VIP levels. Our cloud acceleration subscription services are delivered through the following majorpremium acceleration products: Type of Services Description of Services Green Channel This product allows our subscribers to transmit digital media files from the internet, which significantlyimproves speed and reliability of such transmission. This is particularly helpful when subscribers need totransmit files that are only available from slow or unreliable data transmission sources, or to transmit a groupof files while having only limited internet connectivity time. Offline Accelerator This product allows our subscribers to engage us to transmit digital media files from the internet on theirbehalf. In addition to our major premium acceleration products, our product, Fast Bird, also accelerates our subscribers’ internet access by increasing thebandwidth of the network system provided by telecommunications service providers. We adopted different strategies and various promotion programs for each VIP level. For example, when we discovered that some of our users werenot aware of our subscription services, we provided users with greater exposure to our subscription services in different parts of our platform and promotedproducts with significant potential interests to specific users. We use our powerful digital data analysis capabilities to explore different areas of user needspreviously unmet by existing functions and research and develop relevant functions based on such analysis. We offer users promotional measures, such asproviding some free trials of premium acceleration services, to show the differences in the data transmission speeds to demonstrate how our premium servicestremendously enhance data delivery speed and overall subscriber experience. In order to promote customer loyalty, we may elevate the VIP levels of our subscribers if they actively engage in our services, for example,frequently participating in reviewing and rating of our products. Once upgraded to certain higher VIP levels, our subscribers may be offered additionalindependent accounts, internally termed as sub-accounts, at no additional charges. Such sub-accounts also allow users to access our premium accelerationservices, at no additional charge. We had a subscriber base of 4.3 million, 4.2 million and 4.3 million as of December 31, 2015, 2016 and 2017, respectively. In this annual report, thenumber of subscribers as of a given day excludes any sub-accounts. Mobile Xunlei Mobile Xunlei is a mobile application that allows users to search, download and consume digital media content on their mobile devices. Themonthly average daily active user of this product was about 7.5 million in 2017. We started to monetize our mobile traffic through advertising sales andgenerated our first mobile advertising revenues in late 2015. Since then, our mobile advertising business has grown rapidly. In 2017, our revenue generatedfrom our mobile advertising business increased by 46.7% from US$14.5 million in 2016 to US$21.2 million in 2017. 52 Moreover, this mobile application also supplements our existing subscriptions business. Many of our mobile application users also became users ofour PC-based Xunlei Accelerator. Cloud computing We launched our cloud computing project in 2014, which crowd-sources idle uplink capacity from internet users who have bought and connectedour proprietary hardware, Zhuanqianbao, or ZQB, to their network router. Our ZQB devices can allocate those users’ idle uplink capacity to us for our furtherallocation to internet content providers. We pay users of our ZQB devices for the use of their idle uplink capacity. To further develop our cloud computing business and at the same time explore emerging blockchain technology, we launched our decentralizedcloud computing product, OneThing Cloud, in 2017. OneThing Cloud is a cloud-based storage and sharing device, which crowd-sources idle uplink capacityfrom our users who have bought and connected their OneThing Cloud devices to their network router. Similar to ZQB, OneThing Cloud can allocate thoseusers’ idle computing resources to us for our further allocation to internet content providers. However, an important difference between OneThing Cloud andZQB is that users of OneThing Cloud can voluntarily participate in OneThing Reward Program and be rewarded with LinkToken, which can be used toredeem for our products and services. The crowd-sourced uplink capacities are valuable resources that we target to commercialize with potential customers such as streaming websites andapp stores. Depending on our own needs, we also utilize those crowd-sourced uplink capacities for our business from time to time, reducing our purchase ofbandwidth from traditional third party carriers. Live video services We launched our live video services in 2016 and adjusted our business model in 2017. Under the new business model, while viewing live onlineperformance given by broadcasters, users may interact on real-time basis with broadcasters, purchase virtual items from us to reward broadcasters they like.Users can access our live video services through Xunlei Live website and mobile app. Xunlei Media Player Xunlei Media Player, which we launched in 2008, is a supplementary tool that helps to deliver a more comprehensive viewing experience of digitalmedia content to the users of Xunlei Accelerator. Xunlei Media Player is our proprietary product that supports both online and offline play of digital mediacontent as well as simultaneous play of digital media content while it is being transmitted by Xunlei Accelerator. Online game services To better serve our users, we offer online games through our online game website and purchase licenses from, or enter into revenue sharingarrangements with, game developers. Such game play platform helps raise the average spending of our subscribers. Online game players can play the gamesfree of charge, but are offered the opportunity to purchase in-game virtual items for a fee to enhance their game-playing experience. In light of the overall decline in the web game market and our intention to allocate more resources on the development of our cloud computingbusiness, we streamlined our online game business by disposing of our web game business in January 2018. After the disposal, we only operate MMOGs andmobile games for our online game services. We may also from time to time offer other ancillary services to cater to users’ needs and to supplement the major services we provide. Technology We provide accelerated data transmission services, available on PC and mobile devices, based on our distributed file locating system, designed toutilize our proprietary file indexing technology. 53 Indexing technology Key elements of our file indexing technology include: File indexing. We have created, and continue to maintain, a proprietary file index database that stores a massive index of unique file signaturesrepresenting all digital media content file that Xunlei Accelerator has found across the internet. Each file signature uniquely identifies the index of a givenfile. We store a list of each unique file’s available data transmission locations from across the internet, which may include both peer and server computers,along with the estimated speed and reliability of each location. Data mining. We also employ data mining algorithms, studying user habits in order to maximize the speed of our data delivery by ranking thekeyword indexes that users search for and placing digital media content more likely to be searched by users in the more easily accessible locations in ournetwork for optimal delivery speed. Distributed internet crawling techniques. Our Xunlei Accelerator network acts as a system of distributed spiders to crawl the internet to search fordigital media content files. Whenever the user initiates data transmission by using our Xunlei Accelerator, the URL of the data transmission location isuploaded to our server. We then use that URL to traverse and locate any other digital media content files that may also be available from the URL’s internetpage repositories. We then update our file index according to each traversal result. Distributed file locating system Our distributed file locating system is based on distributed computing architecture, which consists of all Xunlei Accelerator clients that are runningand connected to the internet at a given time, along with the server addresses stored in our file index database. When users launch Xunlei Accelerator on anetwork-connected device, they are automatically connected to our distributed file locating system and contribute their bandwidth and computing power toour distributed file locating system, which enables users to locate and connect efficiently. Key technologies include: Multi-protocol file transfer technology. Our multi-protocol file transfer technology allows our product client to transmit, in parallel, from multiplesources that may use different file transfer protocols. Our multi-protocol file transfer technology significantly increases the number of data transmissionsources available to further enhance data transmission performance. Distributed file locating system. Our distributed file locating system helps users discover the best data transmission locations from across theinternet, where a particular file may be transmitted or streamed for optimal performance. When a user requests data transmission using our Xunlei Accelerator,distributed file locating system will algorithmically prioritize and select from among the file’s available data transmission locations an optimized subset ofURLs based on their respective transmit speed and reliability, which is estimated through real-time collaborative interactions between our file index serverand our massive network of active Xunlei Accelerator clients across the internet. 54 Network transport and traversal optimization. Our proprietary software algorithms perform dynamic internet bandwidth and throughput assessmentsacross the Xunlei network and optimization of traffic routing to identify the most efficient path for data transport. These algorithms are designed to maximizedelivery speed, reliability and efficiency, and support significant growth in network usage. Cloud-based implementation We provide cloud acceleration subscription services powered by our indexing technology and distributed file locating system. Our platform iscompatible with different operating systems and hardware devices. As part of the infrastructure for the subscription services, except for proprietary loadbalancing and resource optimization algorithms, we maintain a virtual private network consisting of 184 co-location centers and over one million third partyservers and over 10,000 servers that we own located throughout China. We maintain proprietary load balancing and resource optimization algorithms, both of which help enhance our mass data mining on user habits tocompile and maintain information on users’ data transmission acceleration needs and requirements. As a cloud service provider, we use data mining for userhabit prediction and co-location purposes. In user habit prediction, we analyze, sample and index user behavior data to help predict user acceleration needsand requirements. For co-location purposes, our program finds the most efficient and stable connection in our network for each transmission task. We alsocooperate with telecom operators, maintaining logics and algorithms for our co-location centers in each telecom operator’s network to enable real-timedynamic allocation of our servers and bandwidth to support user acceleration requirements. Our system automatically optimizes user connections based onkey factors such as provincial network, firewall penetration and interconnection among various telecom operators. Advertising services We provide advertising services primarily through various forms of advertisements placed on our PC websites and mobile platform. We had 120, 115and 112 advertisers in 2015, 2016 and 2017, respectively, and generated mobile advertising revenue for the first time in the fourth quarter of 2015, and it hasgrown rapidly since then. The above number of advertisers include the number of third party platforms, such as Guangdiantong, we cooperate with in eachcorresponding year. Our brand advertisers include international and domestic companies that operate in a variety of industries. A significant majority of ouradvertisers purchase our advertising services through third-party advertising agencies. We focus on providing advertisers with creative and cost-effectiveadvertising solutions. We strive to creatively utilize our integrated service interface in designing a particular advertising campaign for advertisers. Marketing We built up our reputation and maintain our popularity primarily through word-of-mouth. We believe satisfied users and customers are more likelyto recommend our services to others. Thus, we continue to focus on improving our services and enhancing our user experience. In the meanwhile, we alsoinvest in a variety of marketing activities to further promote our brand awareness among existing and potential users as well as other customers. For example,we host or attend various public relations events, such as seminars, conferences and trade shows, in the advertising, online video and online game industriesto attract users and advertisers. To retain and drive the growth of our subscribers, we market our premium paid services and place subscription advertisementsat prominent locations throughout our integrated service offerings. Intellectual property Protection of our intellectual property Our patents, copyrights, trademarks, trade secrets and other intellectual property rights are critical to our business. We rely on a combination ofpatent, copyright, trademark, trade secret and other intellectual property-related laws in the PRC and contractual restrictions to establish and protect ourintellectual property rights. In addition, we require all of our employees to enter into agreements requiring them to keep confidential all information theyobtain during the course of their employment relating to our technology, methods, business practices, customers and trade secrets. As of December 31, 2017,we had 49 patents granted in the PRC and four granted in the United States, while another 32 patent applications are being examined by the State IntellectualProperty Office of the PRC. We also seek to vigorously protect our Xunlei brand and the brands of our other services. As of December 31, 2017, we haveapplied to register 561 trademarks, of which we have received 193 registered trademarks in different applicable trademark categories including one trademarkregistered with World Intellectual Property Organization. 55 Digital media data monitoring and copyright protection We take initiatives to protect third-party copyrights. The internet industry in China suffers from copyright infringement issues and online digitalmedia content providers are frequently involved in litigation based on allegations of infringement or other violations of copyrights. Assisted by anintellectual property team dedicated to copyright protection, we have implemented internal procedures pursuant to the legal requirements under relevantPRC laws and regulations to promptly disenable the download URL of contents for which we receive notice of infringement from the legitimate rights holder,and we work closely with the relevant regulatory authorities in China to ensure compliance with all relevant rules and regulations. We seek assurances in ourcontracts with digital media content providers that (i) they have the legal right to license the digital media data for the uses we require; (ii) the digital mediacontent itself as well as the authorization or rights granted to us neither breach any applicable law, regulations or public morals, nor impair any third-partyrights; and (iii) they will indemnify us for losses resulting from both the non-compliance of such digital media content with the laws and claims from thirdparties. As of the date of this annual report, we have implemented several initiatives to further commit to copyright protection. In May 2014, we entered intoa content protection agreement with the MPAA and its members, which are six major U.S. entertainment content providers. In that agreement, we agreed toimplement a comprehensive system of measures designed to prevent unauthorized downloading of and access to such content providers’ works. Afterbeginning the roll-out for several months, we suspended implementation of the filter but have identified and are in the process of implementing a new filter.Even with the implementation of a new filter, however, our copyright protection measures would not be able to fully protect us against copyrightinfringement suits. For example, in January 2015, a number of MPAA member studios filed 28 copyright infringement lawsuits against us on 28 videoproducts 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 onAugust 21, 2017. The court held, among others, that we infringed the plaintiffs’ copyright on 13 of 28 video products and were required by the court tocompensate the plaintiff for a total of RMB1.4 million. As of the date of this annual report, those cases are awaiting decisions of appellate court. For details,see “Item 3. Key Information—D. Risk Factors—Risks related to our business—We face and expect to continue to face copyright infringement claims andother related claims, including claims based on content available through our services, which could be time-consuming and costly to defend and may resultin damage awards, injunctive relief and/or court orders, divert our management’s attention and financial resources and adversely impact our business” and“Item 8. Financial Information—A. Consolidated Statements and Other Financial Information—Legal Proceedings.” User data safety User data safety is a significant advantage we offer to our users. We try to improve user experience by usually maintaining two to four copies of onespecific user file for data recovery in extreme circumstances such as system shutdown, private transmission backbone network problems and othercontingencies beyond our control. The read and write characteristics of our distributed file locating system is identical to those of hard disks, and our uniqueuser file decomposition and encryption algorithm enables us to maintain high standards for user data safety. Competition Due to our multiple service offerings, we face competition in several aspects of the internet services market in China. We believe that the keycompetitive factors in the overall internet services market in China include brand recognition, user traffic, technology platform and monetization abilities.We also face competition for the advertisement budgets of our advertisers from other internet companies and other forms of media. 56 Regulation This section sets forth a summary of the most significant rules and regulations that affect our business activities in China. Regulation on catalogue relating to foreign investment Investment activities in the PRC by foreign investors are subject to the Catalogue for the Guidance of Foreign Investment Industry, or the Catalogue,which was promulgated and is amended from time to time by the Ministry of Commerce and the National Development and Reform Commission, or theNDRC. The Catalogue divides industries into three categories: encouraged, restricted and prohibited. Industries not listed in the Catalogue are generallyopen to foreign investment unless specifically restricted by other PRC regulations. Pursuant to the latest Catalogue amended in June 2017, which took effect on July 28, 2017, industries listed therein are divided into two categories:encouraged industries and the industries within the catalogue of special management measures, or the Negative List. The Negative List is further divided intotwo sub-categories: restricted industries and prohibited industries. Establishment of wholly foreign-owned enterprises is generally allowed in industries notincluded in the Negative List. For the restricted industries within the Negative List, some of them are limited to equity or contractual joint ventures, while insome cases Chinese partners are required to hold the majority interests in such joint ventures. In addition, restricted category projects are subject togovernment approvals and certain special requirements. Foreign investors are not allowed to invest in industries in the prohibited category. The provision ofvalue-added telecommunications services falls in the restricted category and the percentage of foreign ownership cannot exceed 50% (excluding e-commerce). The provision of internet cultural operating service (including online game operation services), internet publication service and onlinetransmission of audio-visual programs service fall in the prohibited category and the foreign investors are prohibited to engage in such services.

Regulation on telecommunications and internet information services The telecommunications industry, including the internet sector, is highly regulated in the PRC. Regulations issued or implemented by the StateCouncil, MIIT, and other relevant government authorities cover many aspects of operation of telecommunications and internet information services,including entry into the telecommunications industry, the scope of permissible business activities, licenses and permits for various business activities andforeign investment. 57 The principal regulations governing the telecommunications and internet information services we provide in the PRC include: ·Telecommunications regulations (2016, revised), or the Telecom Regulations. The Telecom Regulations categorize all telecommunicationsbusinesses in the PRC as either basic or value-added. Value-added telecommunications services are defined as telecommunications andinformation services provided through public network infrastructures. The “Catalogue of Telecommunications Business,” an attachment to theTelecom Regulations and updated by MIIT’s Notice on Adjusting the Catalogue of Telecommunications Business effective from April 1, 2003and amended on March 1, 2016, categorizes various types of telecommunications and telecommunications-related activities into basic or value-added telecommunications services, according to which, internet information services, or ICP services, are classified under the second categoryof value-added telecommunications businesses and the CDN services, the internet access services and the internet data center services areclassified under the first category of value-added telecommunications business. Under the Telecom Regulations, commercial operators of value-added telecommunications services must obtain the VATS License covering the business classified under the relevant category from MIIT or itsprovincial level counterparts. ·Administrative measures on internet information services (2017, revised), or the Internet Measures. According to the Internet Measures, acommercial ICP service operator must obtain a VATS License from the relevant government authorities before engaging in any commercial ICPservice within the PRC. When the ICP service involves areas of news, publication, education, medical treatment, health, pharmaceuticals,medical equipment and other industry and if required by law or relevant regulations, prior approval from the respective regulating authoritiesmust be obtained prior to applying for the VATS License covering the ICP services from MIIT or its local branch at the provincial level.Moreover, an ICP service operator must display its ICP License number in a conspicuous location on its website and must monitor its website toremove categories of harmful content that are broadly defined. ·Administrative measures for telecommunications business operating license (2009, revised), or the Telecom License Measures. The TelecomLicense Measures set forth more specific provisions regarding the types of licenses required to operate value-added telecommunicationsservices, the qualifications and procedures for obtaining such licenses and the administration and supervision of such licenses. For example, anICP service operator conducting business within a single province must apply for the VATS License from MIIT’s applicable provincial levelcounterpart, while an ICP service operator providing ICP services across provinces must apply for a Trans-regional VATS License directly fromMIIT. The appendix to the VATS License must detail the permitted activities to be conducted by the ICP service operator. An approved ICPservice operator must conduct its business in accordance with the specifications recorded on its VATS License. The VATS License is subject toannual report requirement. An ICP service operator shall report certain information to the issuing authorities through the administrative platformin the first quarter every year. Such information includes the business performance of the telecommunications business in the previous year,service quality, the actual implementation of the network and information security guarantee systems and measures, among others. ICP serviceoperator shall be responsible for the truthfulness of the information in the annual report. ·Detailed rules on the administration of internet websites (2005), which set forth that the website operator is required to apply for the ICP filingfrom MIIT or its local branches at the provincial level on its own or through the access service provider. ·Regulations for administration of foreign-invested telecommunications enterprises (2016, revised), or the FITE Regulations. The FITERegulations set forth detailed requirements with respect to, among others, capitalization, investor qualifications and application procedures inconnection with the establishment of a foreign-invested telecommunications enterprise. Under the FITE Regulations, a foreign entity isprohibited from owning more than 50% of the total equity interest in any value-added telecommunications service business in the PRC and themajor foreign investor in any value-added telecommunications service business in the PRC shall have good and profitable records andoperating experiences in such industry. 58 ·Circular on strengthening the administration of foreign investment in and operation of value-added telecommunications business (2006).Under this circular, a domestic PRC company that holds a VATS License is prohibited from leasing, transferring or selling the VATS License toforeign investors in any form, and from providing any assistance, including providing resources, sites or facilities, to foreign investors thatconduct value-added telecommunications business illegally in the PRC. Further, the domain names and registered trademarks used by anoperating company providing value-added telecommunications service shall be legally owned by such company and/or its shareholders. Inaddition, such company’s operation premises and equipment should comply with the approved covering region on its VATS License, and suchcompany should establish and improve its internal internet and information security policies and standards and emergency managementprocedures. ·Circular of the Ministry of Industry and Information Technology on Clearing up and Regulating the Internet Access Service Market (2017),which, among others, further strengthens the supervision and management of the applications of cloud computing, big data and otherapplications. For an enterprise that conducts the CDN business without a VATS License specifically covering such business, it must submit awritten commitment to the original license issuing authority before March 31, 2017, undertaking that an eligible VATS License will beobtained by the end of 2017. If such enterprise fails to make the commitment on time, it must carry out business activities strictly in compliancewith their existing licenses. Furthermore, if the enterprise fails to obtain the eligible VATS License as committed it should terminate the relevantbusiness starting from January 1, 2018. To comply with these PRC laws and regulations, we operate our websites through Shenzhen Xunlei, our PRC variable interest entity. We, throughShenzhen Xunlei or its subsidiaries, currently hold a VATS License covering its ICP services expiring on April 30, 2020 and another VATS License for itsprovision of could computing services including internet data center services and internet access services expiring on January 19, 2021, and own theessential trademarks and domain names in relation to our value-added telecommunications business. Shenzhen Onething has obtained an updated VATSLicense to cover the CDN service for our cloud computing business. Under various laws and regulations governing ICP services, ICP services operators are required to monitor their websites. They may not produce,duplicate, post or disseminate any content that falls within the prohibited categories and must remove any such content from their websites, including anycontent that: ·opposes the fundamental principles determined in the PRC’s Constitution; ·compromises state security, divulges state secrets, subverts state power or damages national unity; ·harms the dignity or interests of the State; ·incites ethnic hatred or racial discrimination or damages inter-ethnic unity; ·sabotages the PRC’s religious policy or propagates heretical teachings or feudal superstitions; ·disseminates rumors, disturbs social order or disrupts social stability; ·propagates obscenity, pornography, gambling, violence, murder or fear or incites the commission of crimes; ·insults or slanders a third party or infringes upon the lawful rights and interests of a third party; or ·includes other content prohibited by laws or administrative regulations.

On April 13, 2005, the State Council promulgated the Certain Decisions on the Entry of the Non-State-owned Capital into the CulturalIndustry. On July 6, 2005, MOC, GAPPRFT, the NDRC and the Ministry of Commerce, jointly adopted the Several Opinions on Canvassing ForeignInvestment into the Cultural Sector. According to these regulations, non-State-owned capital and foreign investors are not allowed to conduct the business oftransmitting audio-visual programs via information network. On December 20, 2007, GAPPRFT and MIIT jointly promulgated the Administrative Provisions on Internet Audio-visual Program Service, or theAudio-visual Program Provisions, which came into effect on January 31, 2008 and was revised on August 28, 2015. The Audio-visual Program Provisionsapply to the provision of audio-visual program services to the public via internet (including mobile network) within the territory of the PRC. Providers ofinternet audio-visual program services are required to obtain a License for Online Transmission of Audio-visual Programs issued by GAPPRFT or completecertain registration procedures with GAPPRFT. Providers of internet audio-visual program services are generally required to be either State-owned or State-controlled by the PRC government, and the business to be carried out by such providers must satisfy the overall planning and guidance catalog for internetaudio-visual program services determined by GAPPRFT. In a press conference jointly held by GAPPRFT and MIIT to answer questions with respect to theAudio-visual Program Provisions in February 2008, GAPPRFT and MIIT clarified that providers of internet audio-visual program services who engaged insuch services prior to the promulgation of the Audio-visual Program Provisions shall be eligible to register their business and continue their operation ofinternet audio-visual program services so long as those providers had not been in violation of the laws and regulations.

However, when we disposed of Xunlei Kankanbusiness, the registered owner of such license was also changed to the purchaser of Xunlei Kankan. We are now in the process of obtaining a new License forOnline Transmission of Audio-Visual Programs and we expect to obtain a new license in late 2018. See “Risk factors—Risks related to our business—We arestrictly regulated in China. Any lack of requisite licenses or permits applicable to our business and any changes in government policies or regulations mayhave a material and adverse impact on our business, financial condition and results of operations.” Regulation on online cultural activities On February 17, 2011, MOC promulgated the new Provisional Measures on Administration of Internet Culture, or the Internet Culture Measures,which became effective as of April 1, 2011, and the Notice on Issues Relating to Implementing the Newly Amended Provisional Measures on Administrationof Internet Culture on March 18, 2011.

On June 3, 2010, MOCpromulgated the Provisional Measures on the Administration of Online Games, pursuant to which the content of the online games are subject to the review ofMOC. These measures set forth a series of prohibitions regarding the content of the online games, including but without limitation the prohibition on contentthat oppose the fundamental principles stated in the PRC Constitution, compromise state security, divulge state secrets, subvert state power or damagenational unity, and content that is otherwise prohibited by laws or administrative regulations. Moreover, in accordance with these measures, ICP serviceoperators engaging in any activities involving the operation of online games, issuance or trading of virtual currency must obtain the Online CultureOperating Permit and handle the censorship procedures for imported online games and the filing procedures for domestically developed online games withMOC and its provincial counterparts. The procedures for the censorship of imported online games must be conducted with MOC prior to the commencementdate of the online operation and the filing procedures for domestic online games must be conducted with MOC within 30 days after the commencement dateof the online operation or the occurrence date of any material alteration of such online games. Regarding virtual currency trading, ICP service operators canonly issue virtual currency in exchange of the service provided by itself rather than trading for service or products provided by third parties. ICP serviceoperators cannot appropriate the advance payment by the players and are not allowed to provide trading service of virtual currency to minors. All thetransactions in the accounts shall be kept in records for a minimum of 180 days. To comply with these laws and regulations, Shenzhen Xunlei and XunleiGames have obtained the Online Culture Operating Permit respectively for operating online games. Further, the online publication of online games is subject to the regulation of SAPPRFT under the Administrative Provisions on Online PublishingServices and ICP service operators must obtain the Network Publication Service License prior to provision of any online game services. On September 28,2009, GAPPRFT, the National Copyright Administration and the National Office of Combating Pornography and Illegal Publications jointly published theNotice Regarding the Consistent Implementation of the “Stipulations on ‘Three Provisions’ of the State Council and the Relevant Interpretations of theState Commission Office for Public Sector Reform and the Further Strengthening of the Administration of Pre-examination and Approval of Internet Gamesand the Examination and Approval of Imported Internet Games”, or the Notice of Three Provisions and Internet Games, which expressly requires that allonline games need to be screened by GAPPRFT through the advanced approvals before they are operated online, and any updated online game versions orany change to the online games shall be subject to further advanced approvals before they can be operated online. In addition, foreign investors areprohibited from operating online games by the forms of Sino-foreign joint ventures, Sino-foreign cooperatives and wholly foreign-owned enterprises. Theindirect functions such as contractual control and technology supply are also prohibited. Moreover, on December 1, 2016, MOC issued the Circular of the Ministry of Culture on Regulating the Operations of Online Games andStrengthening Interim and Ex-Post Regulation, which will become effective on May 1, 2017. MOC further clarified the scope of online game operation in thecircular. If an enterprise conducts technical testing of online games by means of, among others, making the online games available for user registration,opening the fee-charging system of the online games or providing client-end software with direct server registration and log-in functions, such enterprise isdeemed to be an online game operator. If an enterprise provides user systems, fee-charging systems, program downloading, publicity and promotion and otherservices for the online game products of another game operator and participates in sharing the revenue from the operations of online games, such enterprise isdeemed as a joint operator, and must bear corresponding liabilities. In addition, enterprises engaging in online game operations must require users to registertheir real names by using valid identity documents and must limit the amount that a user may top up each time in a single game. In addition, the enterprisesare required to send information that requires confirmation by users when they top up or make the payments, and the contact details for protecting users’rights and interests must be indicated conspicuously in an online game. Our online game services are currently operated by Shenzhen Xunlei, which holds an Internet Publication License for its publication of onlinegames. Such license will expire on September 17, 2022. We also require the developers of certain online games to obtain the requisite approvals of relevantonline games from SAPPRFT, and make the filings with MOCT, for relevant online games. See “Risk factors—Risks related to our business—We may not beable to successfully address the challenges and risks we face in the online games market, such as a failure to acquire and operate popular, high-quality gamesor to obtain all the licenses required to operate online games, which may subject us to penalties from relevant authorities, including the discontinuance of ouronline game business.” 62 Regulation on anti-fatigue system, real-name registration system and parental guardianship project In April 2007, GAPPRFT and several other government agencies issued a circular requiring the implementation of an anti-fatigue system and a real-name registration system by all PRC online game operators to curb addictive online game playing by minors. Under the anti-fatigue system, three hours orless of continuous playing by minors, defined as game players under 18 years of age, is considered to be “healthy,” three to five hours to be “fatiguing,” andfive hours or more to be “unhealthy.” Game operators are required to reduce the value of in-game benefits to a minor player by half if the minor has reachedthe “fatiguing” level, and to zero once reaching the “unhealthy” level. To identify whether a game player is a minor and thus subject to the anti-fatigue system, a real-name registration system must be adopted to requireonline game players to register their real identity information before playing online games. The online game operators are also required to submit the identityinformation of game players to the public security authority for verification. In July 2011, GAPPRFT, together with several other government agencies,jointly issued the Notice on Initializing the Verification of Real-name Registration for the Anti-Fatigue System on Online Games, or the Real-nameRegistration Notice, to strengthen the implementation of the anti-fatigue and real-name registration system. The main purpose of the Real-name RegistrationNotice is to curb addictive online game playing by minors and protect their physical and mental health. This notice indicates that the National CitizenIdentity Information Center of the Ministry of Public Security will verify identity information of game players submitted by online game operators. The Real-name Registration Notice also imposes stringent penalties on online game operators that do not implement the required anti-fatigue and real-nameregistration systems properly and effectively, including terminating their online game operations. In January 2011, MOC, together with several other government agencies, jointly issued a Circular on Printing and Distributing ImplementationScheme regarding Parental Guardianship Project for Minors Playing Online Games to strengthen the administration of online games and protect thelegitimate rights and interests of minors. This circular indicates that online game operators must have person in charge, set up specific service webpages andpublicize specific hotlines to provide parents with necessary assistance to prevent or restrict minors’ improper game playing behavior. Online game operatorsmust also submit a report regarding its performance under the Parental Guardianship Project to the local MOC office each quarter. We have developed and implemented an anti-fatigue and compulsory real-name registration system in our online games, and will cooperate with theNational Citizen Identity Information Center to launch the identity verification system upon the issuance of relevant implementing rules. For game playerswho do not provide verified identity information, we assume that they are minors under 18 years of age. In order to comply with the anti-fatigue rules, we setup our system so that after three hours of playing our online games, minors only receive half of the virtual items or other in-game benefits they wouldotherwise earn, and after playing for more than five hours, minors would receive no in-game benefits. Regulation on online game virtual currency On February 15, 2007, MOC, the People’s Bank of China and other relevant government authorities jointly issued the Notice on FurtherStrengthening Administrative Work on the Internet Cafes and Online Games, or the Internet Cafes Notice, pursuant to which the People’s Bank of China isdirected to strengthen the administration of virtual currency in online games to avoid any adverse impact on the economy and financial system. This noticeprovides that the total amount of virtual currency issued by online game operators and the amount purchased by individual game players should be strictlylimited, with a strict and clear division between virtual transactions and real transactions carried out by way of electronic commerce. It also provides thatvirtual currency shall only be used to purchase virtual items. On June 4, 2009, MOC and Ministry of Commerce jointly issued the Notice on Strengtheningthe Administrative Work on Virtual Currency of Online Games, pursuant to which no enterprise may concurrently provide both virtual currency issuanceservice and virtual currency transaction service. In addition, the Provisional Measures on the Administration of Online Games require companies that (i) issueonline game virtual currency (including prepaid cards and/or pre-payment or prepaid card points) or (ii) offer online game virtual currency transactionservices to apply for the Online Culture Operating Permit from provincial branches of MOC. The regulations prohibit companies that issue online gamevirtual currency from providing services that would enable the trading of such virtual currency. Any company that fails to submit the requisite applicationwill be subject to sanctions, including but not limited to termination of operation, confiscation of incomes and fines. The regulations also prohibit onlinegame operators from allocating virtual items or virtual currency to players based on random selection through lucky draw, wager or lottery that involves cashor virtual currency directly paid by the players. In addition, companies that issue online game virtual currency must comply with certain specificrequirements, for example, online game virtual currency can only be used for products and services related to the issuance company’s own online games. 63 To comply with these regulations, Shenzhen Xunlei and Xunlei Games have obtained the Online Culture Operating Permit for issuing online gamevirtual currency, and have filed their issuance of virtual currency with the local branch of MOC in Guangdong. Regulation on internet publication SAPPRFT (formerly the GAPPRFT) is the government agency responsible for regulating publication activities in the PRC. On June 27, 2002, MIITand GAPPRFT jointly promulgated the Tentative Administration Measures on Internet Publication, or the Internet Publication Measures, which took effecton August 1, 2002.

Pursuant to the Electronic Publication Rules, if a PRC company iscontractually authorized to publish foreign electronic publications, it must obtain the approval of, and register the copyright license contract with, theGAPPRFT. Shenzhen Xunlei holds an Internet Publication License for the publication of internet games with an expiry date of September 17, 2022. See “Riskfactors—We may not be able to successfully address the challenges and risks we face in the online games market, such as a failure to acquire and operatepopular, high-quality games or to obtain all the licenses required to operate online games, which may subject us to penalties from relevant authorities,including the discontinuance of our online game business.” Regulation on internet privacy The PRC Constitution states that PRC law protects the freedom and privacy of communications of citizens and prohibits infringement of such rights.In recent years, PRC government authorities have enacted legislation on internet use to protect personal information from any unauthorized disclosure. TheInternet Measures prohibit ICP service operators from insulting or slandering a third party or infringing upon the lawful rights and interests of a third party.Pursuant to the BBS Measures, ICP service operators that provide electronic messaging services must keep users’ personal information confidential and mustnot disclose such personal information to any third party without the users’ consent, unless such disclosure is required by law. The regulations furtherauthorize the relevant telecommunications authorities to order ICP service operators to rectify unauthorized disclosure. ICP service operators are subject tolegal liability if the unauthorized disclosure results in damages or losses to users. The PRC government, however, has the power and authority to order ICPservice operators to turn over personal information if an internet user posts any prohibited content or engages in illegal activities on the internet. Under theSeveral Provisions on Regulating the Market Order of Internet Information Services issued by MIIT on December 29, 2011, without the consent of a user, anICP operator may not collect any user personal information or provide any such information to third parties. An ICP service operator shall expressly informthe users of the method, content and purpose of the collection and processing of such user personal information and may only collect such informationnecessary for the provision of its services. An ICP service operator is also required to properly keep the user personal information, and in case of any leak orlikely leak of the user personal information, the ICP service operator shall take immediate remedial measures and in severe consequences, to make animmediate report to the telecommunications regulatory authority.

Under the circumstance that the internet service provider is aware that an internet user is infringingupon the civil rights or interests of another person and fails to take necessary measures, the internet service provider shall be jointly liable for suchinfringement with such internet user. Regulation on intellectual property rights The PRC has adopted comprehensive legislation governing intellectual property rights, including copyrights, patents, trademarks and domainnames. Copyright law Under the Copyright Law (1990), as revised in 2001 and 2010, and its related Implementing Regulations (2002), as revised in 2013, creators ofprotected works enjoy personal and property rights, including, among others, the right of dissemination via information network of the works. The term of acopyright, other than the rights of authorship, alteration and integrity of an author which shall be unlimited in time, is life plus 50 years for individualauthors and 50 years for corporations. To address the problem of copyright infringement related to content posted or transmitted on the internet, the PRC National CopyrightAdministration and MIIT jointly promulgated the Measures for Administrative Protection of Copyright Related to Internet on April 29, 2005. Thesemeasures, which became effective on May 30, 2005, apply to acts of automatically providing services such as uploading, storing, linking or searching works,audio or video products, or other contents through the internet based on the instructions of internet users who publish contents on the internet, withoutediting, amending or selecting any transmitted content. When imposing administrative penalties upon the act which infringes upon any users’ right ofcommunication through information networks, the Measures for Imposing Copyright Administrative Penalties, promulgated in 2009, shall be applied. Pursuant to the Regulation on Protection of the Right of Communication through Information Network (2006), as amended in 2013, an ICP serviceprovider may be exempted from indemnification liabilities under certain circumstances: ·any ICP service provider, who provides automatic internet access service upon instructions of its users or provides automatic transmissionservice of works, performance and audio-visual products provided by its users, will not be required to assume the indemnification liabilities if (i)it has not chosen or altered the transmitted works, performance and audio-visual products; and (ii) it provides such works, performance andaudio-visual products to the designated user and prevents any person other than such designated user from obtaining the access. ·any ICP service provider who, for the sake of improving network transmission efficiency, automatically provides to its own users, based on thetechnical arrangement, the relevant works, performances and audio-visual products obtained from any other ICP service providers will not berequired to assume the indemnification liabilities if (i) it has not altered any of the works, performance or audio-visual products that areautomatically stored; (ii) it has not affected such original ICP service provider in grasping the circumstances where the users obtain the relevantworks, performance and audio-visual products; and (iii) when the original ICP service provider revises, deletes or shields the works, performanceand audio-visual products, it will automatically revise, delete or shield the same based on the technical arrangement. 68 ·any ICP service provider, who provides its users with information memory space for such users to provide the works, performance and audio-visual products to the general public via the information network, will not be required to assume the indemnification liabilities if (i) it clearlyindicates that the information memory space is provided to the users and publicizes its own name, contact person and web address; (ii) it has notaltered the works, performance and audio-visual products that are provided by the users; (iii) it is not aware of or has no reason to know theinfringement of the works, performance and audio-visual products provided by the users; (iv) it has not directly derived any economic benefitfrom the provision of the works, performance and audio-visual products by its users; and (v) after receiving a notice from the right holder, it hasdeleted such works, performance and audio-visual products as alleged for infringement pursuant to such regulation. ·any ICP service provider, who provides its users with search services or links, will not be required to assume the indemnification liabilities if,after receiving a notice from the rights holder, it has deleted the works, performance and audio-visual products as alleged for copyrightinfringement pursuant to this regulation. However, the ICP service provider shall be subject to joint liabilities for copyright infringement if it isaware of or has reason to know the infringement of the works, performance and audio-visual products to which it provides links. In December 2012, the Supreme People’s Court of China promulgated the Provisions on Certain Issues Related to the Application of Law in theTrial of Civil Cases Involving Disputes over Infringement of the Right of Dissemination through Information Networks, which provides that the courts willrequire ICP service providers to remove not only links or content that have been specifically mentioned in the notices of infringement from rights holders,but also links or content they “should have known” to contain infringing content. The provisions further provide that where an ICP service provider hasdirectly obtained economic benefits from any content made available by an internet user, it has a higher duty of care with respect to internet users’infringement of third-party copyrights. To comply with these laws and regulations, we have implemented internal procedures to monitor and review the content we have licensed fromcontent providers before they are released on our websites and platforms and remove any infringing content promptly after we receive notice of infringementfrom the legitimate rights holder. Patent law The National People’s Congress adopted the Patent Law in 1984, and amended it in 1992, 2000 and 2008, respectively. A patentable invention,utility model or design must meet three conditions: novelty, inventiveness and practical applicability. Patents cannot be granted for scientific discoveries,rules and methods for intellectual activities, methods used to diagnose or treat diseases, animal and plant breeds or substances obtained by means of nucleartransformation or designs that are mainly used for marking the pattern, color or combination of these two of prints. The State Intellectual Property Officeunder the State Council is responsible for receiving, examining and approving patent applications. A patent is valid for a twenty-year term in the case of aninvention and a ten-year term in the case of a utility model or design, starting from the application date. A third-party user must obtain consent or a properlicense from the patent owner to use the patent except for certain specific circumstances provided by law. Otherwise, the use will constitute an infringementof the patent rights. Among the patent applications we have filed as of December 31, 2017, 39 were granted in the PRC, while another 13 applications arebeing examined by the State Intellectual Property Office of the PRC. Trademark law Registered trademarks are protected under the Trademark Law adopted in 1982 and amended in 1993, 2001 and 2013 and its implementation rules.The PRC Trademark Office of SAIC is responsible for the registration and administration of trademarks throughout the PRC. The Trademark Law has adopteda “first-to-file” principle with respect to trademark registration. Where a trademark for which a registration has been made is identical or similar to anothertrademark that has already been registered or been subject to a preliminary examination and approval for use on the same kind of or similar commodities orservices, the application for registration of such trademark may be rejected. Any person applying for the registration of a trademark shall not prejudice theexisting right of others obtained by priority, nor shall any person register in advance a trademark that has already been used by another person and hasalready gained “sufficient degree of reputation” through that person’s use. After receiving an application, the PRC Trademark Office will make a publicannouncement if the relevant trademark passes the preliminary examination. Within three months after such public announcement, any person may file anopposition against a trademark that has passed a preliminary examination. The PRC Trademark Office’s decisions on rejection, opposition or cancellation ofan application may be appealed to the PRC Trademark Review and Adjudication Board, whose decision may be further appealed through judicialproceedings. If no opposition is filed within three months after the public announcement period or if the opposition has been overruled, the PRC TrademarkOffice will approve the registration and issue a registration certificate, upon which the trademark is registered and will be effective for a renewable ten-yearperiod, unless otherwise revoked. As of December 31, 2017, we had applied for registration of 561 trademarks, of which 193 had been successfully registeredin different applicable trademark categories, including one trademark registered with World Intellectual Property Organization. 69 Domain name The domain names are protected under the Administrative Measures on the Internet Domain Names promulgated by MIIT on August 24, 2017 andeffective on November 11, 2017. MIIT is the major regulatory body responsible for the administration of the PRC internet domain names, under supervisionof which China Internet Network Information Center, or CNNIC, is responsible for the daily administration of CN domain names and Chinese domain names.On September 25, 2002, CNNIC promulgated the Implementation Rules of Registration of Domain Name, or the CNNIC Rules, which was renewed on June 5,2009 and May 29, 2012, respectively. Pursuant to the Administrative Measures on the Internet Domain Names and the CNNIC Rules, the registration ofdomain names adopts the “first to file” principle and the registrant shall complete the registration via the domain name registration service institutions. In theevent of a domain name dispute, the disputed parties may lodge a complaint to the designated domain name dispute resolution institution to trigger thedomain name dispute resolution procedure in accordance with the CNNIC Measures on Resolution of the Top Level Domains Disputes, file a suit to thePeople’s Court or initiate an arbitration procedure. We have registered www.xunlei.com and other domain names. Regulation on tax PRC enterprise income tax The PRC enterprise income tax is calculated based on the taxable income determined under the PRC laws and accounting standards. On March 16,2007, the National People’s Congress of China enacted a new PRC Enterprise Income Tax Law, or the EIT Law, which became effective on January 1, 2008and revised on January, 2017. On December 6, 2007, the State Council promulgated the Implementation Rules to the PRC Enterprise Income Tax Law, or theImplementation Rules, which also became effective on January 1, 2008. On December 26, 2007, the State Council issued the Notice on Implementation ofEnterprise Income Tax Transition Preferential Policy under the PRC Enterprise Income Tax Law, or the Transition Preferential Policy Circular, which becameeffective simultaneously with the EIT Law. The EIT Law imposes a uniform enterprise income tax rate of 25% on all domestic enterprises, including foreign-invested enterprises unless they qualify for certain exceptions, and terminates most of the tax exemptions, reductions and preferential treatments availableunder previous tax laws and regulations. Under the EIT Law and the Transition Preferential Policy Circular, enterprises that were established before March 16,2007 and already enjoyed preferential tax treatments will continue to enjoy them (i) in the case of preferential tax rates, for a period of five years from January1, 2008; during the five-year period, the tax rate will gradually increase from 15% to 25%, or (ii) in the case of preferential tax exemption or reduction for aspecified term, until the expiration of such term. In addition, the EIT Law and its implementation rules permit qualified high and new technology enterprises,or HNTEs, to enjoy a reduced enterprise income tax rate of 15%. Moreover, under the EIT Law, enterprises organized under the laws of jurisdictions outside China with their “de facto management bodies” locatedwithin China may be considered PRC resident enterprises and therefore subject to PRC enterprise income tax at the rate of 25% on their worldwide income.The Implementation Rules define the term “de facto management body” as the management body that exercises full and substantial control and overallmanagement over the business, productions, personnel, accounts and properties of an enterprise. In addition, the Circular Related to Relevant Issues on theIdentification of a Chinese holding Company Incorporated Overseas as a Residential Enterprise under the Criterion of De Facto Management Bodiesissued by the SAT on April 22, 2009 provides that a foreign enterprise controlled by a PRC enterprise or a PRC enterprise group will be classified as a“resident enterprise” with its “de facto management bodies” located within China if the following requirements are satisfied: (i) the senior management andcore management departments in charge of its daily operations function mainly in the PRC; (ii) its financial and human resources decisions are subject todetermination or approval by persons or bodies in the PRC; (iii) its major assets, accounting books, company seals, and minutes and files of its board andshareholders’ meetings are located or kept in the PRC; and (iv) at least half of the enterprise’s directors or senior management with voting rights reside in thePRC. Although the circular only applies to offshore enterprises controlled by PRC enterprises or PRC enterprise groups and not those controlled by PRCindividuals or foreigners, the determining criteria set forth in the circular may reflect the SAT’s general position on how the “de facto management body” textshould be applied in determining the tax resident status of offshore enterprises, regardless of whether they are controlled by PRC enterprises, individuals orforeigners. 70 Although we are not controlled by a PRC enterprise or PRC enterprise group and we do not believe that we meet all of the above-mentionedconditions, substantial uncertainty exists as to whether we will be deemed a PRC resident enterprise for enterprise income tax purpose. In the event that weare considered a PRC resident enterprise, we would be subject to the PRC enterprise income tax at the rate of 25% on our worldwide income, but thedividends that we receive from our PRC subsidiaries would be exempt from the PRC withholding tax since such income is exempted under the PRCEnterprise Income Tax Law for a PRC resident enterprise recipient. See “Item 3. Key Information—D. Risk factors—Risks related to doing business in China—Our global income may be subject to PRC taxes under the PRC EIT Law, which may have a material adverse effect on our results of operations.” Under applicable PRC tax laws and regulations, arrangements and transactions among related parties may be subject to audit or scrutiny by the PRCtax authorities within ten years after the taxable year when the arrangements or transactions are conducted. We could face material and adverse taxconsequences if the PRC tax authorities were to determine that the contractual arrangements among Giganology Shenzhen, our wholly-owned subsidiary inChina and Shenzhen Xunlei, our variable interest entity in China and its shareholders were not entered into on an arm’s-length basis and therefore constitutedunfavorable transfer pricing arrangements. Unfavorable transfer pricing arrangements could, among other things, result in an upward adjustment to the taxliability of Shenzhen Xunlei, and the PRC tax authorities may impose interest on late payments on Shenzhen Xunlei for the adjusted but unpaid taxes. Ourresults of operations may be materially and adversely affected if Shenzhen Xunlei’s tax liabilities increase significantly or if it is required to pay interest onlate payments. PRC value added tax On May 24, 2013, the Ministry of Finance, or the MOF, and the SAT issued the Circular on Tax Policies in the Nationwide Pilot Collection ofValue Added Tax in Lieu of Business Tax in the Transportation Industry and Certain Modern Services Industries, or the Pilot Collection Circular. The scopeof certain modern services industries under the Pilot Collection Circular extends to the inclusion of radio and television services. On March 23, 2016, theMOF and the SAT jointly issued the Circular on the Pilot Program for Overall Implementation of the Collection of Value Added Tax Instead of Business Tax,or Circular 36, which took effect on May 1, 2016. Pursuant to the Circular 36, all of the companies operating in construction, real estate, finance, modernservice or other sectors which were required to pay business tax are required to pay VAT, in lieu of business tax. The VAT rate is 6%, except for rate of 11%for real estate sale, land use right transferring and providing service of transportation, postal sector, basic telecommunications, construction, real estate lease;rate of 17% for providing lease service of tangible property; and rate of zero for specific cross-bond activities. PRC dividend withholding tax Under the PRC tax laws effective prior to January 1, 2008, dividends paid to foreign investors by foreign-invested enterprises were exempt from PRCwithholding tax. Pursuant to the EIT Law and the Implementation Rules, dividends generated after January 1, 2008 and payable by a foreign-investedenterprise in China to its foreign enterprise investors are subject to a 10% withholding tax, unless any such foreign investor’s jurisdiction of incorporationhas a tax treaty with China that provides for a different withholding arrangement. Under the China-HK Taxation Arrangement, income tax on dividendspayable to a company resident in Hong Kong that holds more than a 25% equity interest in a PRC resident enterprise may be reduced to a rate of 5%. InFebruary 2018, the SAT issued a new circular on issues relating to “beneficial owner” in tax treaties, or Circular No. 9, which will become effective on April1, 2018 and replace Circular No. 601. Circular No. 9 provides a more flexible guidance to determine whether the applicant engages in substantive businessactivities. Furthermore, under the Administrative Measures for Non-Resident Enterprises to Enjoy Treatments under Tax Treaties, non-resident taxpayerswhich satisfy the criteria for entitlement to tax treaty benefits may, at the time of tax declaration or withholding declaration through a withholding agent,enjoy the tax treaty benefits and are subject to further regulation by the tax authorities. If non-resident taxpayers fail to claim the tax treaty benefits with thewithholding agent, or the materials and the information contained in the relevant reports and statements provided to the withholding agent do not satisfy thecriteria for entitlement to tax treaty benefits, the withholding agent shall withhold tax pursuant to the provisions of PRC tax laws. In addition, according to atax circular issued by SAT in February 2009, if the main purpose of an offshore arrangement is to obtain a preferential tax treatment, the PRC tax authoritieshave the discretion to adjust the preferential tax rate enjoyed by the relevant offshore entity. Although Xunlei Computer is currently wholly owned by XunleiNetwork HK, we cannot assure you that we will be able to enjoy the preferential withholding tax rate of 5% under the China-HK Taxation Arrangement. 71 Regulation on labor laws and social insurance Pursuant to the PRC Labor Law and the PRC Labor Contract Law, employers must execute written labor contracts with full-time employees. Allemployers must compensate their employees with wages equal to at least the local minimum wage standards. All employers are required to establish a systemfor labor safety and sanitation, strictly abide by state rules and standards and provide employees with workplace safety training. Violations of the PRC LaborContract Law and the PRC Labor Law may result in the imposition of fines and other administrative liabilities. Criminal liability may arise for seriousviolations. In addition, employers in China are obliged to provide employees with welfare schemes covering pension insurance, unemployment insurance,maternity insurance, work-related injury insurance, medical insurance and housing funds. To comply with these laws and regulations, we have caused all of our full-time employees to enter into labor contracts and provide our employeeswith the proper welfare and employment benefits. Regulation on foreign exchange control and administration Foreign exchange regulation in the PRC is primarily governed by the following regulations: ·Foreign Exchange Administration Rules, or the Exchange Rules, promulgated by the State Council on January 29, 1996, which was amendedon January 14, 1997 and on August 5, 2008 respectively; and ·Administration Rules of the Settlement, Sale and Payment of Foreign Exchange, or the Administration Rules promulgated by the People’s Bankof The PRC on June 20, 1996. Under the Exchange Rules, Renminbi is convertible for current account items, including the distribution of dividends, interest payments, trade andservice-related foreign exchange transactions. As for capital account items, such as direct investments, loans, security investments and the repatriation ofinvestment returns, however, the conversion of foreign currency is still subject to the approval of, or registration with, SAFE or its competent local branches;while for the foreign currency payments for current account items, the SAFE approval is not necessary for the conversion of Renminbi except as otherwiseexplicitly provided by laws and regulations. Under the Administration Rules, enterprises may only buy, sell or remit foreign currencies at banks that areauthorized to conduct foreign exchange business after the enterprise provides valid commercial documents and relevant supporting documents and, in thecase of certain capital account transactions, after obtaining approval from SAFE or its competent local branches. Capital investments by enterprises outside ofthe PRC are also subject to limitations, which include approvals by or registration with the Ministry of Commerce, SAFE and the National Development andReform Commission, or their respective competent local branches. On July 21, 2005, the PRC government changed its policy of pegging the value of theRenminbi to the U.S. dollar. Under the new policy, the Renminbi is permitted to fluctuate within a band against a basket of certain foreign currencies. On August 29, 2008, SAFE issued the Circular on the Relevant Operating Issues Concerning the Improvement of the Administration of the Paymentand Settlement of Foreign Currency Capital of Foreign-Invested Enterprises, or Circular No. 142. Pursuant to Circular No. 142, the Renminbi capital fromthe settlement of foreign currency capital of a foreign-invested enterprise must be used within the business scope as approved by the applicable governmentauthority and unless it is otherwise provided by law, such Renminbi capital cannot be used for domestic equity investment. Documents certifying thepurposes of the settlement of foreign currency capital into Renminbi, including a business contract, must also be submitted for the settlement of the foreigncurrency. In addition, SAFE strengthened its oversight of the flow and use of the Renminbi capital converted from foreign currency registered capital of aforeign-invested company. The use of such Renminbi capital may not be altered without the SAFE’s approval, and such Renminbi capital may not be used torepay Renminbi loans if such loans have not been used. Violations of the Circular No. 142 could result in severe monetary fines or penalties. In March 2015,SAFE issued SAFE Circular No. 19, which took effect on June 1, 2015 and replaced SAFE Circular No. 142 and subsequently issued the Notice of the StateAdministration of Foreign Exchange on Reforming and Standardizing the Policy on the Management of Foreign Exchange Settlement under CapitalAccount, or SAFE Circular No. 16 on June 9, 2016. Although SAFE Circular No. 19 and SAFE Circular No. 16 allow the use of RMB converted from theforeign currency-denominated capital for equity investments in the PRC, the restrictions continue to apply as to foreign-invested enterprises’ use of theconverted RMB for purposes beyond the business scope, issuing loans to non-associated companies (except the cases expressly allowed in the businessscope), or issuing inter-company RMB loans. 72 On November 19, 2012, SAFE promulgated the Circular of Further Improving and Adjusting Foreign Exchange Administration Policies onForeign Direct Investment, or Circular 59, which became effective on December 17, 2012. Circular 59 substantially amends and simplifies the current foreignexchange procedure. The major developments under Circular 59 are that the opening of various special purpose foreign exchange accounts (e.g. pre-establishment expenses account, foreign exchange capital account, guarantee account) no longer requires the approval of SAFE. Furthermore, multiplecapital accounts for the same entity may be opened in different provinces, which was not possible before the issuance of Circular 59. Reinvestment of RMBproceeds by foreign investors in the PRC no longer requires SAFE approval or verification, and remittance of foreign exchange profits and dividends by aforeign-invested enterprise to its foreign shareholders no longer requires SAFE approval. On May 10, 2013, SAFE promulgated the Circular on Printing and Distributing the Provisions on Foreign Exchange Administration over DomesticDirect Investment by Foreign Investors and the Supporting Documents, which specifies that the administration by SAFE or its local branches over directinvestment by foreign investors in the PRC shall be conducted by way of registration. Institutions and individuals shall register with SAFE and/or itsbranches for their direct investment in the PRC. Banks shall process foreign exchange business relating to the direct investment in the PRC based on theregistration information provided by SAFE and its branches. In February 2015, SAFE promulgated the Circular of the State Administration of Foreign Exchange on Further Simplifying and Improving thePolicies Concerning Foreign Exchange Control on Direct Investment, or SAFE Circular No. 13, which took effect on June 1, 2015. SAFE Circular No. 13delegates the authority to enforce the foreign exchange registration in connection with the inbound and outbound direct investment under relevant SAFErules to certain banks and therefore further simplifies the foreign exchange registration procedures for inbound and outbound direct investment. On April 26,2016, SAFE issued the Circular of the State Administration of Foreign Exchange on Further Promoting Trade and Investment Facilitation and ImprovingAuthenticity Review, which provides that for outward remittances of the profit equivalent of more than US$ 50,000 (exclusive) by domestic institutions,banks shall review the relevant board resolution (or the partnership resolution) on profit distribution, the original copies of tax return forms and the financialstatements evidencing the profits, in accordance with the principle of authentic transactions. Regulation on foreign exchange registration of offshore investment by PRC residents On October 21, 2005, SAFE issued the Circular on Several Issues concerning Foreign Exchange Administration for Domestic Residents to Engagein Financing and in Return Investments via Overseas Special Purpose Companies, or Circular No. 75, which went into effect on November 1, 2005. CircularNo. 75 and related rules provide that if PRC residents establish or acquire direct or indirect interests of offshore special purpose companies, or offshore SPVs,for the purpose of financing these offshore SPVs with assets of, or equity interests in, an enterprise in the PRC, or inject assets or equity interests of PRCentities into offshore SPVs, they must register with local SAFE branches with respect to their investments in offshore SPVs. Circular No. 75 also requires PRCresidents to file changes to their registration if their offshore SPVs undergo material events such as capital increase or decrease, share transfer or exchange,merger or division, long-term equity or debt investments, and provision of guaranty to a foreign party. SAFE promulgated the Circular on Relevant IssuesConcerning Foreign Exchange Control on Domestic Residents’ Offshore Investment and Financing and Roundtrip Investment through Special PurposeVehicles, or SAFE Circular No. 37, on July 4, 2014, which replaced the SAFE Circular No. 75. SAFE Circular No. 37 requires PRC residents to register withlocal branches of SAFE in connection with their direct establishment or indirect control of an offshore entity, for the purpose of overseas investment andfinancing, with such PRC residents’ legally owned assets or equity interests in domestic enterprises or offshore assets or interests, referred to in SAFE CircularNo. 37 as a “special purpose vehicle.” The term “control” under SAFE Circular No. 37 is broadly defined as the operation rights, beneficiary rights ordecision-making rights acquired by the PRC residents in the offshore special purpose vehicles or PRC companies by such means as acquisition, trust, proxy,voting rights, repurchase, convertible bonds or other arrangements. SAFE Circular No. 37 further requires amendment to the registration in the event of anychanges with respect to the basic information of the special purpose vehicle, such as changes in a PRC resident individual shareholder, name or operationperiod, or any significant changes with respect to the special purpose vehicle, such as increase or decrease of capital contributed by PRC individuals, sharetransfer or exchange, merger, division or other material event. If the shareholders of the offshore holding company who are PRC residents do not completetheir registration with the local SAFE branches, the PRC subsidiaries may be prohibited from distributing their profits and proceeds from any reduction incapital, share transfer or liquidation to the offshore company, and the offshore company may be restricted in its ability to contribute additional capital to itsPRC subsidiaries. Moreover, failure to comply with SAFE registration and the amendment requirements described above could result in liability under PRClaw for the evasion of applicable foreign exchange restrictions. On February 13, 2015, SAFE issued SAFE Circular No. 13, which took effect on June 1, 2015.SAFE Circular No. 13 has delegated to the qualified banks the authority to register all PRC residents’ investment in “special purpose vehicle” pursuant to theSAFE Circular No. 37, except that those PRC residents who have failed to comply with the SAFE Circular No. 37 will continue to fall within the jurisdictionof the relevant local SAFE branches and must make their supplementary registration application with such local SAFE branches. 73 We have requested PRC residents holding direct or indirect interest in our company to our knowledge to make the necessary applications, filingsand amendments as required under Circular No. 37 and other related rules. However, we may not be informed of the identities of all the PRC residents holdingdirect or indirect interest in our company, and we cannot provide any assurances that these PRC residents will comply with our request to make or obtain anyapplicable registrations or comply with other requirements required by Circular No. 37 or other related rules. The failure or inability of our PRC residentshareholders to make any required registrations or comply with other requirements under Circular No. 37 and other related rules may subject such PRCresidents or our PRC subsidiaries to fines and legal sanctions and may also limit our ability to raise additional financing and contribute additional capitalinto or provide loans to (including using the proceeds from our initial public offering) our PRC subsidiaries, limit our PRC subsidiaries’ ability to paydividends or otherwise distribute profits to us, or otherwise adversely affect us. Regulation on employee share options On December 25, 2006, the People’s Bank of China promulgated the Administrative Measures for Individual Foreign Exchange. On February 15,2012, SAFE issued the Notices on Issues concerning the Foreign Exchange Administration for Domestic Individuals Participating in Stock Incentive Plansof Overseas Publicly-Listed Companies, or the Stock Option Rules, which replaced the Application Procedures of Foreign Exchange Administration forDomestic Individuals Participating in Employee Stock Ownership Plans or Stock Option Plans of Overseas Publicly-Listed Companies issued by SAFE onMarch 28, 2007. Pursuant to the Stock Option Rules, PRC residents who are granted shares or stock options by companies listed on overseas stock exchangesaccording to the stock incentive plans are required to register with SAFE or its local branches, and PRC residents participating in the stock incentive plans ofoverseas listed companies shall retain a qualified PRC agent, which could be a PRC subsidiary of such overseas publicly-listed company or another qualifiedinstitution selected by such PRC subsidiary, to conduct the SAFE registration and other procedures with respect to the stock incentive plans on behalf ofthese participants. Such participants must also retain an overseas entrusted institution to handle matters in connection with their exercise of stock options,purchase and sale of corresponding stocks or interests, and fund transfer. In addition, the PRC agents are required to amend the SAFE registration with respectto the stock incentive plan if there is any material change to the stock incentive plan, the PRC agents or the overseas entrusted institution or other materialchanges. The PRC agents shall, on behalf of the PRC residents who have the right to exercise the employee share options, apply to SAFE or its local branchesfor an annual quota for the payment of foreign currencies in connection with the PRC residents’ exercise of the employee share options. The foreignexchange proceeds received by the PRC residents from the sale of shares under the stock incentive plans granted and dividends distributed by the overseaslisted companies must be remitted into the bank accounts in the PRC opened by the PRC agents before distribution to such PRC residents. In addition, thePRC agents shall file each quarter the form for record-filing of information of the Domestic Individuals Participating in the Stock Incentive Plans of OverseasListed Companies with SAFE or its local branches. Our PRC citizen employees who have been granted share options or restricted shares, or PRC grantees, are subject to the Stock Option Rules. If we orour PRC grantees fail to comply with the Individual Foreign Exchange Rule and the Stock Option Rules, we and/or our PRC grantees may be subject to finesand other legal sanctions. We may also face regulatory uncertainties that could restrict our ability to adopt additional share incentive plans for our directorsand employees under PRC law. In addition, the State Administration for Taxation has issued certain circulars concerning employee share awards. Under thesecirculars, our employees working in the PRC who exercise share options or hold the vested restricted shares will be subject to PRC individual income tax.Our PRC subsidiaries have obligations to file documents related to employee share awards with relevant tax authorities and to withhold individual incometaxes of those employees who exercise their share options or hold the vested restricted shares. If our employees fail to pay or we fail to withhold their incometaxes according to relevant laws and regulations, we may face sanctions imposed by the tax authorities or other PRC government authorities. 74 Regulation on dividend distributions The principal regulations governing the distribution of dividends paid by wholly foreign-owned enterprises include: ·Company Law (2005); ·Wholly Foreign-Owned Enterprise Law (1986), as amended in 2000 and 2016; and ·Wholly Foreign-Owned Enterprise Law Implementation Regulations (1990), as amended in 2001. Under these regulations, wholly foreign-owned enterprises in the PRC may pay dividends only out of their accumulated profits, if any, as determinedin accordance with PRC accounting standards and regulations. In addition, a wholly foreign-owned enterprise in the PRC is required to set aside at least 10%of its after-tax profit based on PRC accounting standards each year to its general reserves until its cumulative total reserve funds reaches 50% of its registeredcapital. The board of directors of a wholly foreign-owned enterprise has the discretion to allocate a portion of its after tax profits to its employee welfare andbonus funds. These reserve funds, however, may not be distributed as cash dividends. Regulation on overseas listings On August 8, 2006, six PRC regulatory agencies, namely, the Ministry of Commerce, the State Assets Supervision and Administration Commission,the State Administration for Taxation, SAIC, CSRC and SAFE, jointly adopted the Regulations on Mergers and Acquisitions of Domestic Enterprises byForeign Investors, or the M&A Rules, which became effective on September 8, 2006 and were amended on June 22, 2009. The M&A Rules purport, amongother things, to require that offshore special purpose vehicles, or SPVs, that are controlled by PRC companies or individuals and that have been formed foroverseas listing purposes through acquisitions of PRC domestic interest held by such PRC companies or individuals, to obtain the approval of the CSRCprior to publicly listing their securities on an overseas stock exchange. On September 21, 2006, the CSRC published a notice on its official websitespecifying documents and materials required to be submitted to it by SPVs seeking CSRC approval of their overseas listings. While the application of theM&A Rules remains unclear, our PRC legal counsel has advised us that based on its understanding of the current PRC laws, rules and regulations and theM&A Rules, prior approval from the CSRC is not required under the M&A Rules for the listing and trading of our ADSs on the NASDAQ Global SelectMarket given that (i) our PRC subsidiaries were directly established by us as wholly foreign-owned enterprises, and we have not acquired any equity interestor assets of a PRC domestic company owned by PRC companies or individuals as defined under the M&A Rules that are our beneficial owners after theeffective date of the M&A Rules, and (ii) no provision in the M&A Rules clearly classifies the contractual arrangements as a type of transaction subject to theM&A Rules. However, our PRC legal counsel has further advised us uncertainties still exist as to how the M&A Rules will be interpreted and implemented and itsopinions summarized above are subject to any new laws, rules and regulations or detailed implementations and interpretations in any form relating to theM&A Rules. If CSRC or another PRC regulatory agency subsequently determines that prior CSRC approval was required for our initial public offering, wemay face regulatory actions or other sanctions from CSRC or other PRC regulatory agencies. These regulatory agencies may impose fines and penalties onour operations, limit our operating privileges, delay or restrict the repatriation of the proceeds from our initial public offering into the PRC or payment ordistribution of dividends by our PRC subsidiaries, or take other actions that could materially adversely affect our business, financial condition, results ofoperations, reputation and prospects, as well as the trading price of our ADSs. In addition, if CSRC later requires that we obtain its approval for our initialpublic offering, we may be unable to obtain a waiver of CSRC approval requirements, if and when procedures are established to obtain such a waiver. Anyuncertainties or negative publicity regarding CSRC approval requirements could have a material adverse effect on the trading price of our ADSs. 75 Regulation on initial coin offerings On September 4, 2017, People’s Bank of China, the Office of the Central Leading Group for Cyberspace Affairs, the MIIT, the State Administrationfor Industry and Commerce, the China Banking Regulatory Commission, the China Securities Regulatory Commission, and the China Insurance RegulatoryCommission jointly promulgated the Announcement on Prevention of Token Fundraising Risks to strengthen the administration of the initial coin offerings(ICOs) activities. Pursuant to the announcement, “token fundraising” refers to a process where fundraisers issue or distribute so-called “cryptocurrencies” toinvestors in exchange for their financial contributions in the form of “virtual currencies”, such as Bitcoin and Ether. All fundraising activities through tokenissuance are prohibited. In addition, token trading platforms are not allowed to engage in the exchange between any statutory currency with tokens and“virtual currencies” and the trading of the tokens or “virtual currencies.” Nor are they allowed to provide quoting services, information intermediary servicesor other services for tokens or “virtual currencies.” We launched LinkToken in 2017. See “Item 4. Information on the Company—B. Business Overview—Our Platform—Cloud Computing” for moreinformation on our LinkToken. While being rewarded with LinkToken by using our OneThing Cloud, users do not make financial contributions in any formof cryptocurrencies. LinkToken cannot be transferred among users in China. We do not believe our LinkToken involves fundraising activities through tokenissuance, nor do we believe that we will be deemed as a token trading platform, which is operated under a completely different business model. However,relevant PRC government authorities may not be of the same view with us and substantial uncertainties exist regarding the interpretation and implementationof relevant PRC laws and regulations. If relevant PRC authority decides that our LinkToken are not in compliance with current laws and regulations,regulatory restrictions may be imposed on us or we may even be required to discontinue relevant business. See “Item 3. Key Information—D. Risk Factors—Our LinkToken may be subject to various regulatory risks in China which may result in penalties that could have a material adverse effect on our businessand results of operations.” C.Organizational Structure The following diagram illustrates our corporate structure, including our subsidiaries and variable interest entity and the subsidiaries of our variableinterest entity, as of the date of this annual report on Form 20-F: 76 Notes:(1)Shenzhen Xunlei is our variable interest entity.

In recent years, we have expanded our products and services from PC-based devices to mobile devices in part through pre-installed acceleration plug-ins on mobile phones to further enlarge our user base and offer our users a wider range of access points. We provide users with quick and easy access to digital media content on the internet through two core products and services, available to users forfree and for a subscription fee, respectively. Our acceleration products and services include Xunlei Accelerator and our cloud acceleration subscriptionservices (delivered through products such as Green Channel and Offline Accelerator). Benefitting from the large user base accumulated by our core product,Xunlei Accelerator, we have further developed various value-added services to meet a fuller spectrum of our users’ digital media content access andconsumption needs. These value-added products and services include our cloud computing services and online game services. In July 2015, we completedthe divesture of our entire stake in our online video streaming platform, Xunlei Kankan, to Beijing Nesound International Media Corp., Ltd., an independentthird party. We generate revenues primarily through the following services: ·Subscription services. We provide cloud acceleration subscription services for subscribers to enable faster and more reliable access to digitalmedia content. Revenues from subscription services contributed to 42.1% of our revenue in 2017. Subscription fees are time-based and areprimarily collected up-front from subscribers on a monthly or yearly basis. ·Online advertising services (including mobile advertising). We provide marketing opportunities on our PC websites and mobile platform toadvertisers. Online advertising revenues contributed to 11.1% of our revenue in 2017. The revenues are derived principally from various formsof advertisements that we place on our mobile platform after we started to generate mobile advertising revenue in the fourth quarter of 2015. ·Product revenue. We sell hardware devices mainly related to cloud computing. Product revenue contributed 16.3% of our revenue in 2017. ·Other internet value-added services. We offer multiple other value-added services, such as our live video and cloud computing services, to ourusers. Revenues from other internet value-added services contributed to 30.5% of our revenue in 2017. Our revenues increased from US$104.8 million in 2015 to US$141.0 million in 2016 and further to US$201.9 million in 2017. We had a net lossattributable to Xunlei Limited of US$13.2 million, US$24.1 million and US$37.8 million in 2015, 2016 and 2017, respectively. Xunlei Kankan and webgame business are accounted for as discontinued operations due to the sale of those two businesses and our consolidated statements of comprehensiveincome/(loss) in this annual report separately classifies the discontinued operations from our remaining business operations for all years presented. Major factors affecting our results of operations Our business and operating results are subject to general factors affecting the internet industry in China, including overall economic growth, whichhas resulted in increases in disposable income and consumer spending, government and industry initiatives accelerating the technological advancement andgrowth of internet industry, the growth of internet usage and penetration rate in China, strong preference of Chinese consumers for accessing digital mediacontent through the internet, the greater availability of digital media content on the internet, and the increasing acceptance of online advertising as part ofadvertisers’ overall marketing strategy and spending. Our results of operations will continue to be affected by such general factors. 80 Our results of operations are also directly affected by a number of company-specific factors, including: Our ability to continue to enhance and innovate our service offerings, including our mobile products and our cloud computing services. As our industry evolves rapidly and user preference for our services may change quickly, our revenues and results of operations significantly dependon our ability to continue enhancing and expanding our service offerings to meet evolving user preference and market demand, and to broaden our user base.We have a proven track record of developing our service offerings to successfully address the preferences of China’s internet users. To address deficiencies ofdigital media content transmission over the internet in China, we provide users with quick and easy access to digital media content on the internet throughtwo core products and services, Xunlei Accelerator and our cloud acceleration subscription services, available to users for free and for a subscription fee,respectively. To meet our users’ digital media content access and consumption needs, we have further developed various value-added services, includingonline game and live video services. Furthermore, we focus more on user behaviors and study users’ life cycles on our platform, so that we can offer relevantservices at the right time and encourage users to continue using our services. An important part of our business plan is to continue transitioning to mobile internet. As an increasing number of users are accessing online servicesthrough mobile devices, we are increasingly expanding our services to mobile devices, particularly through cooperation with smartphone makers, includingXiaomi, which currently offers our mobile acceleration plug-in pre-installed on its new phones and as updates on its existing phones. We intend to furtherwork with more smartphone makers in China so that a larger number of mobile users can benefit from our mobile products, including acceleration and higherdownloading success rates. We have also launched our cloud computing project to allocate idle uplink capacity to internet content providers and other internet users in need.We gather idle uplink capacity from internet users who have bought and connected our proprietary ZQB and OneThing Cloud devices to their networkrouter. Our ZQB devices and OneThing Cloud can allocate those users’ idle computing resources to us for our further allocation to internet content providersand other internet users. We pay users of our ZQB device for the use of their idle computing resources. For the users of our OneThing Cloud, they canvoluntarily participate in our OneThing Reward Program and be rewarded with LinkToken, which can be used to redeem for our products and services. Thecomputing resources gathered from ZQB and OneThing Cloud devices are valuable resources that we target to commercialize with potential customers suchas streaming websites and app stores. Depending on our own needs, we also utilize those crowd-sourced capacities for our own business from time to time,reducing our purchase of bandwidth from traditional third party carriers. Our ability to further monetize our user base. Our revenues and results of operations depend on our ability to further monetize our user base, to convert more users to subscribers and to increasethe spending of our subscribers. With enhanced knowledge of user behavior and preferences, we offer a diverse range of premium services tailored to theirindividual needs. For example, our cloud acceleration subscription services offer users value-added services for speed. We intend to further monetize our userbase and aim to convert users to subscribers by expanding our offering of value-added services, such as cloud-based storage and mobile access. We plan toprovide one-stop services for our users, in terms of accessing content and storage and synchronization of content across devices, including mobile devicesand PC. 81 Our ability to maintain our technology leadership and cost-efficient infrastructure. Our results of operations depend on our ability to maintain our technology leadership, with innovations such as our mobile technology, our uplinkcapacity crowdsourcing technology and our cloud acceleration technology. Our mobile technology allows users to access content from anywhere, our uplinkcapacity crowdsourcing technology enables us to utilize the idle capacity available from our large user base, and our cloud acceleration technology enablesusers to access content in an efficient manner. Our proprietary technology and highly scalable massive distributed computing network form our corecompetitive advantage, enabling us to deliver superior transmission acceleration services and enhanced user experience anywhere and with an efficient sortof acceleration. Our resource discovery network leverages our distributed computing power, computing and storage capacity and significantly reduces ourreliance on servers operated by us. As part of our expansion strategy, we plan to devote substantial resources to research and development in order to betterserve our users, particularly to our cloud computing services and mobile products and services. Therefore, the expenses associated with our research anddevelopment are expected to increase in the near future. However, we plan to continue to increase the uplink capacity we crowdsource through our cloudcomputing services, which is expected to reduce our bandwidth cost, contribute to the cost efficiency of our overall infrastructure and generate additionalrevenue when we sell those capacity to third parties. Our ability to control our costs and operating expenses. Our results of operations depend on our ability to control our costs and operating expenses. We expect our bandwidth costs to continue to increaseas we grow our business and raise the number of subscribers, although we expect such costs would be partly offset by the fact that we expect to source anincreasing amount of bandwidth from our cloud computing services. In addition, our operating expenses are expected to increase in the future, since weexpect increased headcount to reflect the growth of our business. We plan to continue to invest in research and development to maintain our technologyleadership, especially to increase our research and development expenses and sales and marketing expenses in relation to our cloud computing services.

Our subscription revenues, as apercentage of our revenues, decreased from 78.6% in 2015 to 64.0% in 2016, and further to 42.1% in 2017. The most significant factor that directly affects our subscription revenues is the number of subscribers. We may maintain our subscriber base in thefuture by expanding our offering of fee-based services, but important factors outside of our control, such as the PRC government’s regulation and censorshipof information disseminated over the internet, may have a material adverse impact on our cloud acceleration services, which in turn may have an adverseeffect on the number of our subscribers and on our revenues and results of operations. For example, in April 2014, the Chinese government initiated acampaign to enhance and enforce its scrutiny on internet content in China, particularly for pornographic content, and various websites were subject topenalties and in some cases outright suspension of website operations. We regularly conducted internal compliance investigation to ensure that the contenttransmitted by our products is in compliance with the strict standards set out by the authorities. We deleted millions of cached files, added thousands ofkeywords to our automatic keyword filtration system and permitted temporary suspension of services by approximately 207,000 existing subscribers as of theend of 2017. See “Item 3. Key Information—D. Risk Factors—Risks related to doing business in China—Regulation and censorship of informationdisseminated over the internet in China have adversely affected our business and may continue to adversely affect our business, and we may be liable for thedigital media content on our platform.” In the future, there may be other laws and regulations that lead to further voluntary or forced removal of content orother measures to ensure compliance with standards set out by relevant regulatory authorities, which may further reduce our subscriber base. To date, we havenot been able to quantify the magnitude and extent of such impact. 82 Online advertising. Our online advertising revenues are derived from various forms of advertisements that we place on our PC websites and mobileplatform. A significant majority of our advertisers purchase our online advertising services through third-party advertising agencies. As is customary in theadvertising industry in China, we pay rebates to third-party advertising agencies and recognize revenues net of these rebates. The revenues from our mobile advertising have grown rapidly since we generated such revenues for the first time in the fourth quarter of 2015 andincreased to US$21.2 million in 2017, accounting for 94.4% of the online advertising revenues. We expect the revenues from mobile advertising tocontinuously increase with our on-going transition to mobile internet. Other advertising revenues decreased from US$3.1 million in 2015 to US$2.4 millionin 2016 and further to US$1.3 million in 2017, primarily due to our sale of Xunlei Kankan in July 2015 and we do not expect to generate significant revenuesin the foreseeable future. For details of our sale of Xunlei Kankan, see “Item 4. Information on the Company — A. History and Development of theCompany.” Product revenue. Product revenue represents the revenue we generate primarily from the sales of hardware devices, ZQB and OneThing Cloud, inrelation to our cloud computing services. The product revenue increased from US$2.5 million in 2015 to US$4.5 million in 2016 and further to US$32.9million in 2017. The significant increase in our product revenue in 2017 was primarily due to the increase in the sales of OneThing Cloud. Other internet value-added services. We actively seek new business opportunities that complement our existing core acceleration business to furtherimprove our users’ overall experience. Revenues from other internet value-added services increased from US$15.1 million in 2015 to US$29.4 million in2016 and further to US$61.6 million in 2017. Revenues of other internet value-added services were generated primarily from our live video services, online game services and our cloudcomputing services. For live video services, users purchase virtual gifts from us and send the gifts they purchase to broadcasters to show their support. Werecognized revenue from the sales of virtual gifts in an amount of US$18.0 million in 2017. Our online games business used to consist of web games, mobilegames and MMOGs. In light of the overall decline in web game market and a shift of our strategy, we streamlined our business and disposed of our web gamebusiness in January 2018. After the disposal, our online game business only operates MMOGs and mobile games. We calculate the number of paying usersduring a given period as the cumulative number of users that have purchased virtual items or other products and services for online games at least onceduring the relevant period. For the years ended December 31, 2015, 2016 and 2017, we had approximately 96,365, 95,464 and 69,017 paying users of ouronline games, respectively. For cloud computing services, we recognize revenue when we provide bandwidth to our customers. We started to generaterevenue from cloud computing services in 2015 and the revenue for the year ended December 31, 2017 increased by 90.9% on a year-over-year basis. Weexpect the revenue will continue to increase with the growth of our cloud computing services. Cost of revenues Our cost of revenues consists primarily of (i) bandwidth costs, (ii) cost of inventories sold, (iii) cost of live video, (iv) depreciation of servers andother equipment (v) payment handling charges, and (vi) other costs. The following table sets forth the components of our cost of revenues by amounts andpercentages of our revenues for the periods presented: For the Year Ended December 31, Continuing operations 2015 2016 2017 (in thousands of US$, except for percentages) Amount % ofRevenues Amount % ofRevenues Amount % ofRevenues Bandwidth costs 37,218 35.5 55,135 39.1 68,441 33.9 Cost of inventories sold 2,621 2.5 4,357 3.1 21,485 10.6 Cost of live video services 204 0.2 2,505 1.8 12,724 6.3 Depreciation of servers and other equipment 4,873 4.6 5,848 4.1 7,647 3.8 Payment handling charges 8,909 8.5 6,919 4.9 4,855 2.4 Other costs 5,425 5.2 5,164 3.7 2,724 1.4 Total 59,250 56. 5 79, 928 56. 7 117,876 58.4 83 Bandwidth costs. Bandwidth costs consist of the fees we pay to telecommunications carriers and other service providers for telecommunicationsservices and for hosting our servers at their internet data centers and to a less extent, the fees we compensate users of our ZQB and OneThing Cloud devicesfor the use of their idle uplink capacity. Bandwidth is a significant component of our cost of revenues. We expect our bandwidth costs to decrease on anabsolute basis because the crowdsourced bandwidth capacity obtained through our cloud computing services may offset some of our bandwidth costs. Fordetails on our cloud computing services, see “Item 4. Information on the Company — B. Business Overview.” Cost of inventories sold. Cost of inventories sold mainly consists of the cost associated with the sale of hardware devices including ZQB andOneThing Cloud, in relation to our cloud computing services. Cost of inventories sold increased from US$2.6 million in 2015 to US$4.4 million in 2016 andfurther to US$21.5 million in 2017. We expect our cost of inventories sold continue to grow due to the growth of our cloud computing services. Cost of live video services. Cost of live video services mainly represents the fees we pay to broadcasters and the talent agencies. We expect such costto continue to grow along with the growth of our live video services. Depreciation of servers and other equipment. Depreciation expenses for servers and other equipment that are directly related to our businessoperations and technical support are included in our cost of revenues. We expect our depreciation expenses to increase on an absolute basis as we continue toinvest in additional servers and other equipment to accommodate the growth of our user and subscriber base, but to decrease as a percentage of our revenuesover time. Payment handling charges. Payment handling charges are the fees we pay to payment channels for cloud acceleration subscription services, onlinegames and other paid services. Users can make payments for such services through third-party online, fixed phone line and mobile phone payment channels.These third-party payment channels typically charge a handling fee for their services. Our subscribers used to make subscription payments through mobilephones. However, as mobile carriers generally charge higher handling fees than other channels, we have modified our subscription fee structure to encourageour subscribers to use other available payment channels. We expect such payment handling charges to decrease as we continue to modify our subscription feestructure. Other costs. Other costs mainly include fast bird service cost, which we pay to telecommunication service providers for accelerating service weprovide for our subscribers’ internet access, and game sharing costs which represent the share of online game revenue remitted to developers of exclusivelicensed games. Operating expenses Our operating expenses consist of (i) research and development expenses, (ii) sales and marketing expenses, (iii) general and administrativeexpenses, and (iv) assets impairment loss. The following table sets forth the components of our operating expenses by amounts and percentages of ourrevenues for the periods presented: For the Year Ended December 31, 2015 2016 2017 (in thousands of US$, except for percentages) Amount % ofRevenues Amount % ofRevenues Amount % ofRevenues Research and development expenses 35,762 34.1 61,169 43.4 66,947 33.2 Sales and marketing expenses 12,411 11.8 14,601 10.4 19,888 9.8 General and administrative expenses 28,619 27.3 26,010 18.4 36,517 18.1 Assets impairment loss — — — — 13,556 6.7 Total 76,792 73.2 101,780 72.2 136,908 67.8 84 Research and development expenses. Research and development expenses consist primarily of salaries and benefits for our research anddevelopment personnel. Expenditures incurred during the research phase are expensed as incurred. Expenditures incurred for the development of theacceleration products prior to the establishment of technological feasibility are expensed when incurred. We expect our research and development expensesto increase in the near term as we continue to expand our research and development team to develop new products and update existing products, particularlyas we plan to continue devoting resources in the development of our cloud computing services and the development and updating of our mobile products. Sales and marketing expenses. Sales and marketing expenses consist primarily of salaries, sales commissions and benefits for our sales andmarketing personnel and marketing and promotional expenses. We expect our sales and marketing expenses to increase in the near term as we expect to hireadditional sales personnel and invest in brand enhancement efforts and the promotion of our products, particularly as we plan to increase our efforts inpromoting our cloud computing services, and Mobile Xunlei. General and administrative expenses. General and administrative expenses consist primarily of salaries and benefits, professional service fees andother administrative expenses. We expect our general and administrative expenses to increase in the near term as our business continues to grow. Assets impairment loss. Assets impairment loss consists of assets written-offs after impairment and recoverability assessment. The assets impairmentwas related to (i) the impairment loss on the purchaser’s payment of the last installment (20%) of the purchase price of Xunlei Kankan, which we disposed ofin July 2015, (ii) the impairment loss of other receivables and prepayments we paid on behalf of Xunlei Kankan, and (iii) a one-off impairment loss onintangible assets from a prior acquisition of Kuaipan Personal. Taxation Cayman Islands We are incorporated in the Cayman Islands. Under the current laws of the Cayman Islands, we are not subject to tax on income or capital gains.Additionally, there is no withholding tax on dividends paid by us to our shareholders. China On March 16, 2007, the PRC National People’s Congress promulgated the EIT Law, adopting a unified EIT rate of 25%. In addition, the EIT Lawalso provides a five-year transitional period starting from its effective date for those enterprises that were established before the date of promulgation of theEIT Law and that were entitled to preferential income tax rates under the then effective tax laws or regulations. On December 26, 2007, the State Councilissued the “Circular for Implementation of the Transitional Preferential Policies for the Enterprise Income Tax.” Pursuant to this Circular, the transitionalincome tax rates for enterprises established in the Shenzhen Special Economic Zone before March 16, 2007 were 18%, 20%, 22%, 24% and 25% for 2008,2009, 2010, 2011 and 2012, respectively. Thus, the applicable EIT rate for Giganology Shenzhen, the VIE and its subsidiaries, which were established in theShenzhen Special Economic Zone before March 16, 2007, was 25% for each of the years 2014, 2015 and 2016. On January 29, 2016, relevant PRC governmental regulatory authorities released further qualification criteria, application procedures andassessment processes for meeting the High and New Technology Enterprise, or HNTE status under the EIT Law which would entitle qualified and approvedentities to a favorable statutory tax rate of 15%. In April 2009, the State Administration for Taxation, or SAT, issued Circular Guoshuihan [2009] No. 203stipulating that entities qualified for the HNTE status should apply with the relevant tax authorities to enjoy the reduced EIT rate of 15% provided under theEIT Law starting from the year when the HNTE certificate becomes effective. In addition, an entity qualified for the HNTE status can continue to enjoy itsremaining tax holiday from January 1, 2008 provided that it has obtained the HNTE certificate according to the new recognition criteria set by the EIT Lawand the relevant regulations. Shenzhen Xunlei possesses such HNTE certificate and is qualified to enjoy a preferential tax rate of 15% for the years endedDecember 31, 2017, 2018 and 2019. We are currently renewing such HNTE certificate for Shenzhen Xunlei. In addition to Shenzhen Xunlei, ShenzhenOnething and Shenzhen Wangwenhua also obtained the HNTE certificate in October 2017 and August 2017, respectively, and therefore enjoy a preferentialtax rate of 15% for the years ended December 31, 2017, 2018 and 2019. 85 According to a policy of the PRC State tax bureau, enterprises that engage in research and development activities are entitled to claim 150% of theresearch and development expenses incurred in a year as tax deductible expenses in determining their tax assessable profits for that year, or Super Deduction.Shenzhen Xunlei has been claiming this Super Deduction in ascertaining its tax assessable profits. In addition, following the approval by the relevant tax authority in July 2010, Shenzhen Xunlei was recognized as an enterprise engaged in softwaredevelopment activities. Accordingly, it is entitled to an enterprise income tax exemption for the first two years after it has profit for tax purpose (the “2-yearExemption”) and a 50% reduction from the third to the fifth year after it has profit for tax purpose (“3-year 50% Reduction”). In December 2013, ShenzhenXunlei obtained the certificate of the Key Software Enterprise for the years ended December 31, 2013 and 2014, which enables Shenzhen Xunlei to enjoy thepreferential tax rate of 10% for the year of 2013 and 2014. As a result, the applicable tax rate of Shenzhen Xunlei for the years ended December 31, 2014,2015 and 2016 were 10%, 15% and 15%, respectively. Pursuant to the relevant PRC regulations, Xunlei Computer is entitled to the 2-year Exemption and 3-year 50% Reduction treatment. The first yearof profitable operation of Xunlei Computer is 2013. Accordingly, the applicable EIT rates for Xunlei Computer were 12.5%, 12.5% and 12.5% for the yearsended December 31, 2015,2016 and 2017, respectively. The term of 50% reduction treatment expired in 2017. Our other subsidiaries and VIE’s subsidiaries,which were established after January 1, 2008, are subject to EIT at a rate of 25%. 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 furtherreduced WHT rate may be available according to the applicable double tax treaty or arrangement). The 10% WHT is generally applicable to any dividends tobe distributed from Giganology Shenzhen and Xunlei Computer to us out of any profits of Giganology Shenzhen and Xunlei Computer derived after January1, 2008. Although Xunlei Computer and Giganology Shenzhen had retained earnings as of December 31, 2016 and December 31, 2017, the directors of thecompany decided to reinvest the retained earnings permanently in China and therefore no such WHT is required. In addition, the current EIT Law treats enterprises established outside the PRC with “effective management and control” located in the PRC as PRCresident enterprises for tax purposes. The term “effective management and control” is generally defined as exercising overall management and control overthe business, personnel, accounting, properties, etc. of an enterprise. If a company is considered as a PRC resident enterprise for tax purposes, it would besubject to the PRC Enterprise Income Tax at the rate of 25% on its worldwide income after January 1, 2008. As of December 31, 2017, the Company has notaccrued for PRC tax on such basis. The Company will continue to monitor its tax status. Results of operations The following table sets forth a summary of our consolidated results of continuing operations by amounts and percentages of our revenues for theyears indicated.

Revenues. Our revenues increased by 43.2% from US$141.0 million in 2016 to US$201.9 million in 2017. The increase was primarily due toincreases in cloud computing revenue and online advertising revenue. Our revenues from subscription services decreased by 5.8% from US$90.2 million in 2016 to US$85.0 million in 2017, primarily due to the decreasein the number of subscribers from 2016 to 2017. Our online advertising revenues increased by 33.2% from US$16.9 million in 2016 to US$22.5 million in 2017, primarily due to an increase inmobile advertising revenue. Our product revenues increased by 624.1% from US$4.5 million in 2016 to US$32.9 million in 2017, primarily due to an increase in sales ofOneThing Cloud devices in 2017. Revenues derived from other internet value-added services increased by 109.4% from US$29.4 million in 2016 to US$61.6 million in 2017,primarily due to increases in revenues from our live video services and cloud computing services. Cost of revenues. Our cost of revenues increased by 47.5% from US$79.9 million in 2016 to US$117.9 million in 2017. The increase in our cost ofrevenues was primarily due to increases in hardware costs and bandwidth costs. 87 Bandwidth costs. Our bandwidth costs increased by 24.1% from US$55.1 million in 2016 to US$$68.4 million in 2017, primarily due to theincreased bandwidth costs associated with our cloud computing business. Cost of inventories sold. Our cost of inventories sold increased by 393.1% from US$4.4 million in 2016 to US$21.5 million in 2017, primarily dueto the increased cost of inventories sold associated with the sale of hardware device, OneThing Cloud. Cost of live video. Our cost of live video services increased by 407.9% from US$2.5 million in 2016 to US$12.7 million in 2017, primarily due tothe increased live video costs associated with the growth of live video service in 2017. Depreciation of servers and other equipment. Depreciation of servers and other equipment increased by 30.8% from US$5.8 million in 2016 toUS$7.6 million in 2017, primarily due to a one-off acceleration in depreciation of servers in an aggregate amount of US$1.3 million. Payment handling charges. Our payment handling charges decreased by 29.8% from US$6.9 million in 2016 to US$4.9 million in 2017, drivenprimarily by a change in the combination of payment channels used by our subscribers. Other costs. These costs decreased by 47.3% from US$5.2 million in 2016 to US$2.7 million in 2017, primarily related to the decreased costsassociated with the fast bird cost and game sharing cost. Gross profit. As a result of the above, our gross profit increased by 37.2% from US$60.3 million in 2016 to US$82.7 million in 2017. Gross profitmargin decreased from 42.8% in 2016 to 41.0 % in 2017, primarily due to our continued investment in cloud computing business. Operating expenses. Our operating expenses increased by 34.5% from US$101.8 million in 2016 to US$136.9 million in 2017, primarily due to (i)our continued development and promotion of cloud computing services, (ii) an increase in staff compensation expenses, and (iii) assets impairment loss. Research and development expenses. Our research and development expenses increased by 9.4% from US$61.2 million in 2016 to US$66.9 millionin 2017. The increase in our research and development expenses was primarily due to an increase in salaries and benefits of our research staff, includinghiring additional engineers for our cloud computing business. Sales and marketing expenses. Our sales and marketing expenses increased by 36.2% from US$14.6 million in 2016 to US$19.9 million in 2017.The increase in our sales and marketing expenses was primarily due to an increase in marketing expenses we incurred in promoting our cloud computingproducts. General and administrative expenses. Our general and administrative expenses increased by 40.4% from US$26.0 million in 2016 to US$36.5million in 2017. The increase in our general and administrative expenses was primarily because (i) we incurred more legal and litigation related expenses dueto settlement we reached for certain cases and (ii) an increase in employee compensation we paid. Assets impairment loss. We recorded assets impairment loss of US$13.6 million in 2017 primarily due to the write-offs in relation to Xunlei Kankan,which we disposed of in July 2015 and Kuaipan Personal, with respect to which we performed an impairment assessment due to a change of our productfocus. Interest income. Our interest income decreased by 8.8% from US$2.2 million in 2016 to US$2.0 million in 2017, primarily due to a decrease of timedeposits in our bank account. Interest expense. Our interest expense remained stable at US$0.2 million in 2016 and 2017, which represented interest expenses accrued for long-term payables to certain shareholders resulting from repurchase of shares in 2014. Other income, net. Our other income increased by 21.2% from US$6.5 million in 2016 to US$7.9 million in 2017, primarily due to an increase ofgovernment grant we received. 88 Income tax benefit. We had an income tax credit of US$2.5 million in 2016 and an income tax benefit of US$2.3 million in 2017. Our income taxbenefit for 2017 was primarily due to the decrease of deferred tax liabilities and increase of deferred tax assets. Net loss from continuing operations. As a result of the above, our net loss increased from US$30.8 million in 2016 to US$44.2 million in 2017. Net income from discontinued operations. Net income from discontinued operations was US$6.6 million in 2016 and US$6.4 million in 2017. Net loss attributable to Xunlei Limited. As a result of the above, we generated a net loss attributable to Xunlei Limited of US$24.1 million andUS$37.8 million in 2016 and 2017, respectively. Year ended December 31, 2016 compared with year ended December 31, 2015. Revenues. Our revenues increased by 34.5% from US$104.8 million in 2015 to US$141.0 million in 2016. The increase was primarily due to theincrease of revenues from cloud computing, mobile advertising and subscription services. Our revenues from subscription services increased by 9.4% from US$82.4 million in 2015 to US$90.2 million in 2016. The increase was mainlyattributable to the growth in average revenue per subscriber. Our number of subscribers as of December 31, 2016 was 4.2 million, compared with 4.3 millionas of December 31, 2015. Our online advertising revenues increased by 251.4% from US$4.8 million in 2015 to US$16.9 million in 2016, primarily due to the growth inmobile advertising which started monetization during the last quarter of 2015. Our product revenues increased by 80.9% from US$2.5 million in 2016 to US$4.5 million in 2017, primarily due to an increase in sales of ZQBdevices. Revenues derived from other internet value-added services increased by 94.9% from US$15.1 million in 2015 to US$29.4 million in 2016, primarilybecause of the growth in cloud computing revenue. Cost of revenues. Our cost of revenues increased by 34.9% from US$59.3 million in 2015 to US$79.9 million in 2016. The increase in our cost ofrevenues was primarily due to an increase in bandwidth cost for cloud computing. Bandwidth costs. Our bandwidth costs increased by 48.1% from US$37.2 million in 2015 to US$55.1 million in 2016, primarily due to an increasein bandwidth costs for our cloud computing business. Cost of inventories sold. Our cost of inventories sold increased by 66.2% from US$2.6 million in 2015 to US$4.4 million in 2016, primarily due tothe increased cost of inventories sold associated with the sale of hardware, such as ZQB. Cost of live video. Our cost of live video increased by 1127.9% from US$0.2 million in 2015 to US$2.5 million in 2016, primarily due to theincreased live video costs associated with our live video growth rapidly after its launch. Payment handling charges. Our payment handling charges decreased by 22.3% from US$8.9 million in 2015 to US$6.9 million in 2016, drivenprimarily by a change in the combination of payment channels used by our subscribers. Depreciation of servers and other equipment. Depreciation of servers and other equipment increased by 20.0% from US$4.9 million in 2015 toUS$5.8 million in 2016, as we invested in additional servers and other equipment in line with the growth of cloud computing business. Other costs. These costs decreased by 4.8% from US$5.4 million in 2015 to US$5.2 million in 2016, primarily related to the decreased costsassociated with the game sharing cost. 89 Gross profit. As a result of the above, our gross profit increased by 33.2% from US$45.3 million in 2015 to US$60.3 million in 2016. Gross profitmargin decreased from 43.2% in 2015 to 42.8% in 2016, primarily due to the continued investments in cloud computing which is still incurring losses. Operating expenses. Our operating expenses increased by 32.5% from US$76.8 million in 2015 to US$101.8 million in 2016, primarily due toexpenses associated with the continued development and promotion of cloud computing and an increase of staff compensation expenses. Research and development expenses. Our research and development expenses increased by 71.0% from US$35.8 million in 2015 to US$61.2 millionin 2016. The increase in our research and development expenses was primarily due to the increase in staff salaries and benefits as a result of increasedheadcount and average compensation, and growth in our cloud computing business. Sales and marketing expenses. Our sales and marketing expenses increased by 17.6% from US$12.4 million in 2015 to US$14.6 million in 2016.The increase in our sales and marketing expenses was primarily due to increased staff compensation expenses and higher marketing spending to newproducts. General and administrative expenses. Our general and administrative expenses decreased by 9.1% from US$28.6 million in 2015 to US$26.0million in 2016. The decrease in our general and administrative expenses was primarily due to the decrease in staff compensation expenses as a result ofdecreased headcount of our general and administrative personnel. Interest income. Our interest income decreased by 63% from US$5.8 million in 2015 to US$2.2 million in 2016 as we converted our offshore bankdeposit from RMB to U.S. dollars since last quarter of 2015 and U.S. dollars-denominated deposits offered lower interest yield. Interest expense. We had an interest expense of US$0.2 million in 2015 and US$0.2 million in 2016, which represented interest expenses accruedfor long-term payables to certain shareholders resulting from repurchase of shares in 2014. Other income, net. Our other income increased by 79% from US$3.6 million in 2015 to US$6.5 million in 2016, primarily due to the decline ofexchange loss in 2016 as a result of an appreciation of U.S. dollars against RMB. Income tax benefit. We had an income tax benefit of US$3.7 million in 2015 and an income tax benefit of US$2.5 million in 2016. Our income taxcredit for the year ended December 31, 2016 was primarily the result of decrease of deferred tax liabilities relating to outside basis difference. Net loss from continuing operations. As a result of the above, we incurred a net loss of US$18.6 million in 2015 and a net loss of US$30.8 million in2016. Net income from discontinued operations. Net income from discontinued operations was US$4.1 million in 2015 and US$6.6 million in 2016. Net loss attributable to Xunlei Limited. As a result of the above, we generated a net loss attributable to Xunlei Limited of US$13.2 million in 2015and a net loss attributable to Xunlei Limited of US$24.1 million in 2016. Inflation Inflation in China has not affected our results of operations in recent years. According to the National Bureau of Statistics of China, the year-over-year percent changes in the consumer price index for December 2015, 2016 and 2017 were increases of 1.6%, 2.1% and 1.6%, respectively. Although we havenot been affected by inflation in the past, we may be affected if China experiences higher rates of inflation in the future. Critical accounting policies We prepare our financial statements in conformity with U.S. GAAP, which requires us to make estimates and assumptions that affect our reporting of,among other things, assets and liabilities, contingent assets and liabilities and revenues and expenses. We regularly evaluate these estimates and assumptionsbased on the most recently available information, our own historical experiences and other factors that we believe to be relevant under the circumstances.Since our financial reporting process inherently relies on the use of estimates and assumptions, our actual results could differ from what we expect. This isespecially true with some accounting policies that require higher degrees of judgment than others in their application. We consider the policies discussedbelow to be critical to an understanding of our audited consolidated financial statements because they involve the greatest reliance on our management’sjudgment. 90 Revenue recognition Subscription revenues We operate a VIP subscription program where VIP subscribers can have access to high speed online acceleration services, online streaming and otheraccess privileges. The subscription fee is time-based and is collected up-front from subscribers except in the cases when they elect to pay via their mobileoperators. The subscription fee is collected when the subscribers pay for their monthly phone bills. The terms of time-based subscriptions range from one totwelve months, with the subscribers having the option to renew the contracts. The receipt of subscription fees is initially recorded as deferred revenue andrevenues are recognized ratably over the period of subscription as services are rendered. Unrecognized portion of the subscription fee beyond 12 monthsfrom balance sheet date is classified as non-current liability. We evaluated the principal versus agent criteria and determined that we are the principal in thetransaction and accordingly record revenues on a gross basis. In determining whether to report revenues gross for the amount of subscription revenues, weassess whether it maintains the principal relationship with the VIP subscribers, whether it bears the credit risk and whether it establishes prices for the endusers. Service fees levied by online system, fixed phone line and mobile payment channels are recorded as the cost of revenues in the same period as therevenues for the subscription fee are recognized. Advertising revenues Advertising revenues are derived principally from advertising arrangements where the advertisers pay to place their advertisements on our platformin different formats over a particular period of time. Such formats include but are not limited to videos, banners, links, logos and buttons. Advertisements on our platform are generally charged on the basis of duration, and advertising contracts are signed to establish the fixed price andthe advertising services to be provided. We enter into advertising contracts with third-party advertising agencies that represent advertisers, as well as directlywith advertisers. A typical contract term would range from a few days to three months. Both third party advertising agencies and direct advertisers are billedat the end of the display period and payments are due usually within three months. Where our customers purchase multiple advertising spaces with different display periods in the same contract, we allocate the total consideration tothe various advertising elements based on their relative fair values and recognize revenues for the different elements over their respective display periods. Wedetermine the fair values of different advertising elements based on the prices charged when these elements were sold on a standalone basis. We recognizerevenues on the elements delivered and defer the recognition of revenues for the fair value of the undelivered elements until the remaining obligations havebeen satisfied. Where all of the elements within an arrangement are delivered uniformly over the contract period, revenues are recognized on a straight linebasis over the contract period. a)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 toadvertisers. Revenues are recognized ratably over the contract period of display based on the following criteria: ·There is a persuasive evidence that an arrangement exists: we will enter into framework and execution contracts with the advertising agencies,specifying price, advertising content, format and timing; ·Price is fixed and determinable: price charged to the advertising agencies is specified in the contracts, including relevant discount and rebaterates; 91 ·Services are rendered: we recognize revenues ratably over the contract period of display; and ·Collectability is reasonably assured: we assess credit history of each advertising agency before entering into any framework and executioncontracts. If the collectability from the agencies is assessed as not reasonably assured, we recognize revenues only when the cash is received andall the other revenues criteria are met. We provide sales incentives in the forms of discounts and rebates to third party advertising agencies based on purchase amount. As the advertisingagencies are viewed as the customers in these transactions, revenues are recognized based on the price charged to the agencies, net of sales rebates providedto the agencies. Sales incentives are estimated and recorded at the time of revenue recognition based on the contracted rebate rates and estimated salesamount based on historical experience. b)Transactions with third party advertising platforms We began to cooperate with third party advertising platforms such as Guangdiantong and Baidu since the fourth quarter of 2015. Under this businessmodel, advertisers put their content on third party advertising platforms, which in turn will dispatch the advertising content to Xunlei’s platforms by certainanalysis systematically. As the third party advertising platforms are viewed as the customers in these transactions, revenue is recognized monthly based onthe data publicized on third party platforms and the price charged to these advertising platforms. c)Transactions with advertisers We also enter into advertisement contracts directly with advertisers. Under these contracts, similar to transactions with third-party advertisingagencies, we recognize revenues ratably over the contract period of display. The terms and conditions, including price, are fixed according the contractsbetween us and the advertisers. We also perform credit assessment of all advertisers prior to entering into contracts. Revenues are recognized based on theamount charged to the advertisers, net of discounts. We recorded sales rebates provided to the agencies and advertisers of US$1,179,000, US$15,000 and US$440,000 for the years ended December 31,2015, 2016 and 2017, respectively. Product revenue We sell hardware devices mainly through online e-commerce platforms and our website. The product revenue is recognized when the device isdelivered to the end customers. Other internet value-added services a)Online game revenues Online games used to consist of web games, mobile games and MMOGs. Users play games through our platform free of charge and are charged forpurchases of virtual items including consumable and perpetual items, which can be utilized in the online games to enhance their game-playing experience.Consumable items represent virtual items that can be consumed by a specific user within a specified period of time. Perpetual items represent virtual itemsthat are accessible to the users’ account over the life of the online game. Pursuant to contracts signed between us and game developers, revenue from the sale of virtual items are shared based on a pre-agreed ratio for eachgame. We enter 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. We mainly provide access to theplatform 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 onan assessment of various factors. The primary factors are whether we act as the principal in offering services to the game players or as agent in the transaction,and the specific requirements of each contract. We determined that for non-exclusive game licensed arrangements, the third party game developers are theprincipal given that the game developers design and develop the game services offered, have reasonable latitude to establish prices of game virtual items, andare responsible for maintaining and upgrading the game content and virtual items. Accordingly, we record online game revenue, net of the portion remitted tothe game developers. 92 Given that online games are managed and administered by the game developers for non-exclusive licensed games, we do not have access to the dataon the consumption details and the types of virtual items purchased by the game players. We have adopted a policy to recognize revenues relating to bothconsumable and perpetual items over the shorter of (i) estimated lives of the games and (ii) the estimated lives of the user relationship with us, which wereapproximately 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 informationindicating a change in the game player behavioral patterns. Exclusive game licensed contracts For exclusive licensing contracts with game developers, the games are maintained and hosted by us. Accordingly, we are determined to be theprincipal. We record online game revenue on a gross basis, with the amount remitted to the game developers reported as cost of revenue. Payment handlingcharges are recognized as cost of revenues when the related revenues are recognized. For exclusive licensed games which are maintained on our server, we have access to the data on the consumption details and types of virtual itemspurchased by the game players. We do not maintain information on consumption details of virtual items, and only have limited information related to thefrequency 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 (i) estimated lives of the games and (ii) the estimated livesof the user relationship with us, which were approximately one to six months for the periods presented. Revenues related to consumable items are recognizedimmediately upon consumption. Game players can purchase prepaid virtual items which can be used to purchase virtual items via online channels. We incur service fees levied bythose 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, we estimate the life of virtual items to be the shorter of the estimated lives of the games andthe estimated lives of the user relationship. The estimated user relationship period is based on data collected from those users who have purchased virtualitems. To estimate the life of the user relationship, we maintain 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. We estimate the life of the user relationship to be the weighted average period from thefirst 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, we consider both games that they operate as well as games in the market that are of a similar nature. We categorizethese games by their nature, such as simulation games, role playing games and others, which appeal to players belonging to different demographics. Weestimate 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 beremoved from the website or terminated altogether. When we launch a new game, they estimate the life of the game and user relationship based on lives ofother similar games in the market until the new game establishes its own history. We also consider the game’s profile, attributes, target audience, and itsappeal to players of different demographic groups in estimating the user relationship period. The consideration of user relationship with each online game is based on our best estimate that takes into account all known and relevantinformation at the time of assessment. Adjustments arising from the changes of estimated lives of virtual items are applied prospectively as such changes areresulted from new information indicating a change in the game player behavioral patterns. Any changes in the estimates of lives of virtual items may result inour revenues being recognized on a basis different from prior periods and may cause our operating result to fluctuate. We periodically assess the estimatedlives of the virtual items and any changes from prior estimates are accounted for prospectively. Any adjustments arising from changes in user relationship as aresult of new information will be accounted as a change in accounting estimate in accordance with ASC 250 Accounting Changes and Error Corrections. 93 We entered into a legally binding agreement to sell our web game business in December 2017. Web game revenue recognized from discontinuedoperations was US$25,160,000, US$15,981,000 and US$11,428,000 for the years ended December 31, 2015, 2016 and 2017, respectively. b)Live video revenue We operate live video platform and users can purchase virtual items which they can then send to broadcasters in the live video platform. Therevenue from live video is recognized at fair value of the virtual items, as we are the principal in this arrangement, based on actual consumption of virtualitems by the paying users. c)Revenues from traffic referral programs We enter into contracts with certain third party portals/websites to earn revenue by redirecting online traffic to these third party portals/websites. Ona monthly basis, we receive data on the user traffic and the related monthly revenue from these third party portals/ websites. Under these programs, werecognize its share of revenues based on contractual rates applied to user traffic redirected to the advertisements of the third parties. d)Revenues from cloud computing As part of our cloud computing service, Project Crystal, we engage in sale of Zhuanqianbao (“ZQB”) and OneThing Cloud. ZQB and OneThingCloud are hardware which could be used as a micro-computer based on Linux system, it also contains CPU, RAM, ROM and input/output devices. ZQB andOneThing Cloud also allow users to share their idle bandwidth with us, in exchange for crystal points and LinkTokens, respectively. Crystal points, which can be converted into cash based on a pre-set exchange rate, will only be given to the users when they successfully sharedunused bandwidth with us, whereas LinkTokens are not convertible into cash but they can be redeemed for the services offered in our platforms under theterms to be determined by us. Although we have not publicly announced the full details of the redemption process, the LinkTokens represent our obligationto deliver future services. Therefore, we receive an identifiable benefit, being the bandwidth, from the users in exchange for the crystal points andLinkTokens. We determine that ZQB and OneThing Cloud sold to users represent identifiable benefit to the users that is separable from the ability to sellbandwidth back to us and the bandwidth purchased from the users represent identifiable benefit to us, which we can reasonably estimate the fair value of thisbenefit, that is separable from ZQB and OneThing Cloud. The sales of ZQB and OneThing Cloud and purchase of excess bandwidth by us are considered separate transactions. Therefore, sales of ZQB andOneThing Cloud are reported as revenue, while crystal points and LinkTokens given for purchase of bandwidth are reported as bandwidth cost. We sell ZQB and OneThing Cloud through online e-commerce platforms. The revenue from ZQB and OneThing Cloud is recognized when the itemis dispatched to the end customers. The LinkTokens issued represent our obligation to deliver future services. Therefore, deferred revenue was recognized for all LinkTokens issued.Revenue will be recognized upon redemption of the LinkTokens, the fair value of which is calculated by bandwidth costs divided by total number ofLinkTokens 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 videostreaming platforms. On a monthly basis, we record the bandwidth we deliver and recognizes revenue from these online video streamers under contractualrates applied (price per GB of bandwidth multiplies total GBs of bandwidth per month). The cost of collecting idle bandwidth is recorded as bandwidth costswithin cost of revenue upon our receiving of idle bandwidth. Revenue is recognized net of return allowances when the products are delivered and title passes to customers. Return allowances, which reduce netrevenues, are estimated based on historical experiences. Product warranties are estimated and recognized at the time we recognizes revenue. The warrantyperiod is one year. We accrue warranty liabilities at the time of sale, based on historical and projected incident rates and expected future warranty costs. 94 Share-based Compensation We awarded a number of share-based compensation options to our employees, officers and directors. The details of these share-based awards and therespective terms and conditions are described in “Share-based compensation” in note 18 to our audited consolidated financial statements for the years endedDecember 31, 2015, 2016 and 2017. Options are accounted for as equity-classified awards because there are no explicit repurchase rights specified in the award documents and thenumber of shares of our common shares issued under these awards are fixed and determined at the time of grants. All options are measured based on the fairvalue of the award on the grant date and recognized as compensation expenses based on the straight-line vesting method, net of estimated forfeitures, overthe requisite service period, which is generally the vesting period. The following table sets forth the options granted that were outstanding as of December 31, 2017: Date of Option Grant Optionsoutstanding Exercise price(US$) Fair value ofoptions (US$) Fair value ofcommon shares(US$) Prior to 2012 130,315 0.016-3.8 — — March 1, 2012 9,500 0.01-3.97 1.01-2.82 2.83 August 1, 2013 200,000 3.97 1.13 3.23 March 1, 2014 10,000 3.97 0.89 3.06 Total 349,815 We estimate the fair value of share options granted using the Black-Scholes option pricing model. The key assumptions used to determine the fairvalue of the options at the relevant grant dates were as follows: (1)Risk-free interest rate. The risk-free interest rates of periods within the contractual life of the share options is based on the U.S. dollar Chinesegovernment bond yield data from Bloomberg as of the valuation dates; (2)Expected dividend yield. We have no history or expectation of paying dividends on our common stock; (3)Expected volatility. We estimate expected volatility based on the average historical volatilities of shares of the comparable publicly listedcompanies from Bloomberg as of the valuation dates; and (4)Expected term. The expected term is estimated by assuming the share options will be exercised in the middle point between the vesting datesand maturity dates. We also awarded a number of restricted shares to our executive officers and employees. The details of these share-based restricted shares and therespective terms and conditions are described in “Share-based compensation” in note 20 to our audited consolidated financial statements for the years endedDecember 31, 2015, 2016 and 2017. The restricted shares are accounted for as equity-classified awards because there are no explicit repurchase rights specified in the relevant documentsand the number of shares of our common shares issued under these awards is fixed and determined at the time of grants. All restricted shares are measuredbased on the fair value of the awards on the grant date and recognized as compensation expenses based on the straight-line vesting method net of estimatedforfeitures over the requisite service period. In 2017, we granted 2,050,000 restricted shares to our executive officers and employees. The compensation costs that we expect to record for thesegrants will be approximately US$0.12 million. Total compensation costs recognized for the years ended December 31, 2015, 2016 and 2017, respectively, are as follows: 95 For the Year Ended December 31, 2015 2016 2017 (In thousands of US$) Sales and marketing expenses 131 98 88 General and administrative expenses 6,701 6,267 5,800 Research and development expenses 2,896 2,983 2,442 Total 9,728 9,348 8,330 Determining the value of our share-based compensation expenses requires the input of highly subjective assumptions, including the expected life ofthe share-based awards, estimated forfeitures and the price volatility of the underlying shares. The assumptions used in calculating the fair value of share-based awards represent our best estimates, but these estimates involve inherent uncertainties and the application of our judgment. As a result, if factorschange and we use different assumptions, our share-based compensation expenses could be materially different in the future. Exchange of Xiaomi Options for Transfer Restrictions As part of the issuance of the series E preferred shares, Xiaomi Ventures and our founders and two other employees, or the Grantees, agreed that (i)Grantees will have the right to purchase certain number of restricted shares of Xiaomi Corporation with a total subscription consideration of not more thanUS$20 million at a subscription price per share that reflects the valuation of Xiaomi Corporation being US$10 billion, or Xiaomi Option; and (ii) theGrantees agreed to impose a transfer restriction on 39,934,162 common shares, 3,394,564 unvested restricted shares, and 360,000 vested and unvested shareoptions owned by the Grantees, or the Transfer Restriction. The Transfer Restriction prohibits the Grantees from transferring their shares to anotherperson/party until April 24, 2019 for one of founders or April 24, 2018 for the rest of the Grantees. The Xiaomi Option and the Transfer Restriction are nottied to the Grantees’ future employment with us. The value of the Transfer Restriction was determined to be significantly greater than the value of Xiaomi Option. In determining the value of theTransfer Restriction, we were assisted by an independent valuation firm, based on data provided by us. The valuation of the Transfer Restriction is estimatedto be US$43.3 million (refer to the valuation methodology below). For the valuation of the Xiaomi Option, we were only able to obtain limited financialinformation from Xiaomi, a private company, to perform a valuation analysis. This information includes high level 2013 revenue data and information of athird party investment transaction that valued the Xiaomi Corporation at US$10 billion in August 2013. Given the lack of financial information, we areunable to determine a more precise estimate of the fair value of the Xiaomi Option on the exchange date. If the fair value of the Xiaomi Option were worthUSD43.3 million, the estimated value of the Transfer Restriction, Xiaomi Corporation itself would need to be estimated at a valuation in excess of US$30billion on March 5, 2014. We do not expect the valuation of the Xiaomi Corporation to increase by 200% from US$10 billion in August 2013 to US$30billion in March 2014. Hence, no incremental benefit was given to the Grantees and no compensation expense was recognized. To determine the fair value of the Transfer Restriction, we valued the common shares with the Transfer Restriction and compared this value to thevalue of the common shares without the restriction. The difference was determined to be the value of the Transfer Restriction. A put option pricing model wasused to determine the discount to be applied to the common shares to arrive at the value of common shares with the Transfer Restriction. Pursuant to thatmodel, we used the cost of a put option, which can be used to hedge the price change before a share subject to transfer restriction can be sold, as the basis todetermine the discount for transfer restrictions. A put option was used because it incorporates certain company-specific factors, including timing of the initialpublic offering or duration of the Transfer Restriction and the volatility of the share price companies engaged in the same industry. Repurchase of Common and Preferred Shares On April 15, 2014, we repurchased from Skyline 469,225 common shares, 27,180 series A preferred shares, 591,451 series A-1 preferred shares,725,237 series B preferred shares and 3,808,943 series D convertible redeemable preferred shares at a consideration of approximately US$24.3 million. Forthe common shares repurchased, we charged the excess of the purchased price over the par value to additional paid in capital. For the preferred shares, wecharged the excess of the purchase price over the carrying value to retain earnings or to additional paid in capital if retain earnings is zero. 96 On April 24, 2014, we repurchased from a number of our existing shareholders the following common and preferred shares for a total considerationof US$49.8 million. We repurchased the following common and preferred shares at a per share price of US$2.82, equal to the issuance price of the series Epreferred shares: ·10,334,679 common shares from Vantage Point Global Limited for US$29.1 million; ·3,860,733 common shares from Aiden & Jasmine Limited for US$10.9 million; ·450,000 Series A preferred shares from Bright Access International Limited for US$1.3 million; ·2,921,868 series B preferred shares from Fidelity Asia Ventures Fund L.P. for US$8.2 million; ·108,960 series B preferred shares from Fidelity Asia Principals Fund L.P. for US$0.3 million. For the common shares repurchased, we charged the excess of the purchased price over the par value to additional paid in capital. For the preferredshares, we charged the excess of the purchase price over the carrying value to retain earnings or to additional paid in capital if retain earnings is zero. Wedetermined the per share fair value of the common shares, series A preferred shares, and series B preferred shares to be US$3.13, US$3.13, and US$3.19,respectively, on the date of repurchase. The repurchase price of US$2.82 was mutually negotiated at the time of the repurchase transactions. There were noother arrangements with the selling shareholders other than the exchange of Xiaomi Option for the Transfer Restrictions. The selling shareholders werewilling to sell its common and preferred shares at the US$2.82 per share price as it would provide them with as a form of liquidity. Impairment of Long-lived Assets We evaluate the program usefulness of licensed copyrights pursuant to the guidance in ASC 920-350 Intangibles—Goodwill and Other:Recognition, which provides that such rights be reported at the lower of unamortized cost or estimated net realizable value. For non-exclusive Content Copyrights which only generate indirect cash flows, we evaluate the net realizable value of our licensed copyrights bythree content categories (i.e. movies, TV series, variety shows and others), which are assessed to be the lowest level of precision for the purpose of performingsuch assessment. If our expectations of programming usefulness, which represents the expected revenues and related net cash flows derived from the content,are revised downward, we then assess whether it is necessary to write down the unamortized cost to the estimated net realizable value. We evaluateprogramming usefulness by category on an annual basis by comparing the unamortized cost to our estimated net realizable value. On a quarterly basis, wealso monitors whether there are indicators of changes in our expected usage of program materials. We estimate net realizable value using expected net cash flows based on expected future levels of advertising revenues. Such estimates considerhistorical amounts and anticipated levels of demand. Expected future revenues are reduced by estimated direct costs to provide access to the website andgenerate the related revenues, including bandwidth costs and server costs. For purposes of estimating revenues for each category of the content, we considerboth expected future advertising revenues sold based on number of impressions delivered as well as advertising sold based on the period of time that it isdisplayed. For exclusive Content Copyrights that generate both direct and indirect cash flows, we evaluate the net realizable value of our licensed copyright ona content by content basis. Impairment is assessed on an annual basis by comparing the unamortized cost to our estimated net realizable value. We estimatethe net realizable value using expected net cash flows based on expected future levels of advertising and content sub-licensing revenues. We estimatedcontent sub-licensing revenue based on management’s expectation of the popularity of the content and we use pricing reference from other similar sub-licensing arrangements. For expected future levels of advertising revenue, we use the same estimation methodology used for the impairment assessment ofnon-exclusive Content Copyrights. For both exclusive and non-exclusive Content Copyrights, there were no impairments for the years ended December 31, 2014 and 2015 because asignificant portion of the content was related to movies and TV series, of which approximately 70% to 90% of the purchase costs of the Content Copyrightshad been amortized during the first year of the licensed period. As such, the unamortized carrying amounts were lower than the respective net realizablevalues when the impairment assessment was performed. 97 For other long-lived assets, we evaluate our long-lived assets for impairment whenever events or changes in circumstances indicate that the carryingamount of an asset may no longer be recoverable. We assess the recoverability of the long-lived assets by comparing the carrying value of the long-livedassets to the estimated undiscounted future cash flows we expect to receive from the use of the assets and their eventual disposition at the lowest level ofidentifiable 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 theassets. If we identify 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. Impairment of Goodwill Impairment of goodwill assessment is performed on at least an annual basis on December 31 or whenever events or changes in circumstancesindicate that the carrying value of the asset may not be recoverable. According to ASC 350-20-35, an entity may assess qualitative factors to determinewhether it is more likely than not (that is, a likelihood of more than 50 percent) that the fair value of a reporting unit is less than its carrying amount,including goodwill. Alternatively, an entity may proceed directly to perform a two-step goodwill impairment test. The first step compares the fair values of areporting unit to its carrying amount, including goodwill. If the fair value of a reporting unit exceeds its carrying amount, goodwill is not consideredimpaired 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 fairvalue of the affected reporting unit’s goodwill to the carrying value of that goodwill. The implied fair value of goodwill is determined in a manner similar toaccounting for a business combination with the allocation of the assessed fair value determined in the first step to the assets and liabilities of the reportingunit. 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. Thisallocation process is only performed for purposes of evaluating goodwill impairment and does not result in an entry to adjust the value of any assets orliabilities. An impairment loss is recognized for any excess in the carrying value of goodwill over the implied fair value of goodwill. The judgment inestimating the fair value of a reporting unit includes estimating future cash flows, determining appropriate discount rates and making other assumptions.Changes in these estimates and assumptions could materially affect the determination of the fair value of a reporting unit. We chose directly to perform a two-step goodwill impairment test. For the first step, the impairment test was performed using a discounted cash flowanalysis to assess the fair value of the company, as a single reporting unit. The discounted cash flow analysis, which requires certain assumptions andestimates regarding economics and future profitability, use cash flow projections for the purposes of impairment reviews covering a five-year period. Cashflows beyond the five-year period are extrapolated using an estimated annual growth of not more than 2%. The growth rates used do not exceed the historicalgrowth of the company. The discount rates used of 18.2% reflect market assessments of the time value and the specific risks. According to the assessment ofthe first step, the fair value of the reporting unit exceeded its carrying amount and the goodwill was not considered impaired. Accordingly, the second stepwas not required. No goodwill impairment losses were recognized for the year ended December 31, 2017 based on the impairment test performed by us. Consolidation The consolidated financial statements include the financial statements of Xunlei Limited, our subsidiaries and our VIE for which Xunlei Limited isthe primary beneficiary. All significant transactions and balances among our subsidiaries, our VIE and us have been eliminated upon consolidation. A subsidiary is an entity in which we, directly or indirectly, control more than one-half of the voting power, has the power to appoint or remove themajority of the members of the board of directors to cast a majority of the votes at meetings of the board of directors or to govern the financial and operatingpolicies of the investee under a statute or agreement among the shareholders or equity holders. 98 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 havesufficient equity at risk for the entity to finance its activities without additional subordinated financial support from other parties. We consolidate entities for which we are the primary beneficiary if the entity’s equity holders do not have the characteristics of a controllingfinancial interest or do not have sufficient equity at risk for the entity to finance its activities without additional subordinated financial support from otherparties. In determining whether Xunlei Limited or its subsidiary is the primary beneficiary of a VIE, we considered whether we have the power to directactivities that are significant to the VIE’s economic performance, including the power to appoint senior management, right to direct company strategy, powerto 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 thatGiganology Shenzhen receives all of the economic benefits and absorbs all of the expected losses from Shenzhen Xunlei and has the power to direct theaforementioned 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 our consolidated financial statements. We monitor theregulatory risk associated with these contractual arrangements. The details of how we manage the regulatory risk are described in “Certain risk andconcentration” in note 25 to our audited consolidated financial statements for the years ended December 31, 2015, 2016 and 2017. Business Combinations We account for acquisitions of entities that include inputs and processes and have the ability to generate economic benefit as businesscombinations. We allocate the purchase price of the acquisition to the tangible assets and identifiable intangible assets acquired based on their estimated fairvalues. The excess of the purchase price over those fair values is recorded as goodwill. Acquisition-related costs are expensed as incurred. Accounts Receivable, Net Accounts receivable are presented net of allowance for doubtful accounts. We evaluate the creditworthiness of each customer at the time whenservices are rendered and continuously monitor the recoverability of the accounts receivable. We use specific identification method in providing for baddebts when facts and circumstances indicate that collection is doubtful and a loss is probable and estimable. If the financial conditions of our customers wereto deteriorate, resulting in an impairment of their ability to make payments, additional allowances may be required. The allowance for doubtful accounts isbased 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 we consider in determining whether we record a bad debt allowance on an individual customer are: ·the customer’s past payment history and whether it fails to comply with its payment schedule; ·whether the customer is in financial difficulty due to economic or legal factors; ·a significant dispute with the customer has occurred; ·other objective evidence which indicates non-collectability of the accounts receivable. If we determine that an allowance is needed for a customer, we will discontinue business with them unless they start to resume payment. Theaccounts receivable is written-off when we cease pursuing collection. Any changes in our estimates may cause our operating results to fluctuate. The accountsreceivable that was fully reserved as of December 31, 2017 was US$0.03 million. The allowances provided for accounts receivable as of December 31, 2017 was US$0.03 million. 99 As of December 31, 2017, we had accounts receivable net of allowances aged beyond one year from the date of invoice in the amount of US$0.6million. Based on our assessment of the customer’s ability to pay, a bad debt allowance was not considered necessary for those amounts. As of the date of thisannual report, a part of those balances have been collected and we continue to actively pursue collection of the remaining balance. Although our general credit term for our customers is 90 days, we do not consider our receivables aged less than one year from the invoice date to bepast due given the general practices we have with our customers in the advertising industry. Typically, we are willing to accept delayed repayment up to oneyear from invoice date if we have assurance that payment will be made as soon as practicable. Accordingly, we did not make significant provisions forbalances aged less than one year as of December 31, 2017. 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 consequencesattributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and tax loss carryforwards. 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 orsettled. 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 thatincludes the enactment date. A valuation allowance is provided to reduce the carrying amount of deferred tax assets if it is considered more likely than notthat some portion, or all, of the deferred tax assets will not be realized. We record a valuation allowance against certain of our deferred income tax assets if itis more likely than not that those assets will not be realized. In evaluating our ability to realize our deferred income tax assets, we consider all availablepositive and negative evidence, including our historical operating results, ongoing tax planning, and forecasts of future taxable income on a jurisdiction byjurisdiction basis. The estimation of future taxable income involves significant judgement and estimates. Based on management’s estimated future taxableincome and all other available evidence, for entities where management concluded that it is more likely than not that the net operating losses carried forwardcan be utilized prior to their respective expiration dates, no valuation allowance is recorded. On January 1, 2008, we adopted the guidance regarding uncertain tax positions. Management evaluates our open tax positions that exist in eachjurisdiction 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 positionis recognized in our consolidated financial statements if it is more likely than not that the position is sustainable upon examination by the relevant taxingauthority. We did not have any significant uncertain tax position and there was no effect on our financial position or results of operations as a result ofimplementing the new guidance. We recognize interest and penalties accrued on any unrecognized tax benefits as a component of income tax expense, ifany. No material interest and penalties were recorded in the year ended December 31, 2017. Commitments and Contingencies In the normal course of business, we are subject to contingencies, such as legal proceedings and claims arising out of our business, that cover a widerange 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 bereasonably estimated. In regards to legal cost, we recorded such costs as incurred. Certain conditions may exist as of the date of this annual report, which may result in a loss to us and such loss will only be resolved when one ormore future events occur or fail to occur. Our management and legal counsel assess such contingent liabilities, and such assessment inherently involve anexercise of judgment. In assessing loss contingencies related to legal proceedings that are pending against us or unasserted claims that may result in suchproceedings, we will consult with our legal counsel and evaluate the perceived merits of any legal proceedings or unasserted claims as well as the perceivedmerits 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 our financial statements. If the assessment indicates that a potentially material loss contingency is notprobable, but is reasonably possible, or is probable but cannot be estimated, then the nature of the contingent liability, together with an estimate of the rangeof possible loss, if determinable and material, would be disclosed. 100 We are involved in a number of cases pending in various courts. These cases are substantially related to alleged copyright infringement andsecurities class actions, as well as routine and incidental matters to its business, among others. Adverse results in these lawsuits may include awards ofdamages and may also result in, or even compel, a change in the Group’s business practices, which could impact our future financial results. We have incurredUS$3.3 million, US$1.7 million and US$9.5 million legal and litigation related expenses for the years ended December 31, 2015, 2016 and 2017,respectively. As of the date of this annual report, we have 42 lawsuits pending against us with an aggregate amount of claimed damages of approximatelyRMB112 million (US$16.8 million) which occurred before December 31, 2017. Among these 42 pending lawsuits, 39 of them were relating to the allegedcopyright infringement in the PRC. We have accrued for US$1.8 million litigation related expenses in “Accrued expenses and other liabilities” in theconsolidated balance sheet as of December 31, 2017, which is the most probable and reasonably estimable outcome. We estimated the litigation compensation based on judgments handed down by the court, out-of-court settlements of similar cases as well as advicesfrom our legal counsel. We are in the process of appealing certain judgments for which the losses had been accrued. Although the results of unsettledlitigation and claims cannot be predicted with certainty, we do not expect that the outcome of the 42 lawsuits will result in the amounts accrued materiallydifferent from the range of reasonably possible losses. In the opinion of management, there was not at least a reasonable possibility we may have incurred amaterial 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 oflitigation is inherently uncertain. Therefore, although management considers the likelihood of such an outcome to be remote, if one or more of these legalmatters were resolved against us in a reporting period for amounts in excess of management’s expectations, our consolidated financial statements for thatreporting period could be materially adversely affected. Recent Accounting Pronouncements See Item 18 of Part III, “Financial Statements—Note 2—Summary of significant accounting policies—Recent accounting pronouncements.” B.Liquidity and Capital Resources We have financed our operations primarily through cash generated from operations and, to a lesser extent, proceeds from private placements ofpreferred shares to investors, and net proceeds received from our initial public offering during the year ended December 31, 2014 while we have financed ouroperations primarily through cash generated from operations during the years ended December 31, 2015, 2016 and 2017. As of December 31, 2017, we hadUS$372.4 million in cash and cash equivalents and short-term investments. As of the same date, we did not have any outstanding bank loans. In respect of our revenues from customers in the advertising industry, although the general credit term for these customers is 90 days, we typicallyare willing to accept delayed repayment up to one year from the invoice date given the general practices we have with our customers in the advertisingindustry. Our practice and collection history may continue to have an impact on our liquidity. In the future, we may rely on dividends and other distributions on equity paid by our wholly-owned PRC subsidiaries for our cash and financingrequirements. There may be potential restrictions on the dividends and other distributions by our PRC subsidiaries. For instance, if Giganology Shenzhen,our PRC subsidiary, incurs debt on its own behalf in the future, the instruments governing the debt may restrict its ability to pay dividends or make otherdistributions to us. The PRC tax authorities may require us to adjust our taxable income under the contractual arrangements Giganology Shenzhen currentlyhas in place with Shenzhen Xunlei in a way that would materially and adversely affect the latter’s ability to pay dividends and other distributions to us. Inaddition, under PRC laws and regulations, Giganology Shenzhen, as a wholly foreign-owned enterprise in the PRC, may pay dividends only out of itsaccumulated profits as determined in accordance with PRC accounting standards and regulations. Wholly foreign-owned enterprises such as GiganologyShenzhen are required to set aside at least 10% of their accumulated after-tax profits each year, if any, to fund a statutory reserve fund, until the aggregateamount of such fund reaches 50% of their respective registered capital. At their discretion, wholly foreign-owned enterprises may allocate a portion of theirafter-tax profits based on PRC accounting standards to staff welfare and bonus funds. These reserve funds and staff welfare and bonus funds are notdistributable as cash dividends. See “Item 3. Key Information—D. Risk factors—Risk related to our corporate structure—We may rely principally ondividends and other distributions on equity paid by our PRC subsidiaries to fund any cash and financing requirements we may have. Any limitation on theability of Giganology Shenzhen and Xunlei Computer to pay dividends to us could have a material adverse effect on our ability to conduct our business.” Inaddition, our investment made as registered capital and additional paid in capital of our subsidiaries, VIE and VIE’s subsidiaries are also subject torestrictions in their distribution and transfer according to the laws and regulations in China. Owing to the above, our subsidiaries, VIE and VIE’s subsidiariesin China are restricted in their ability to transfer their net assets to us in terms of cash dividends, loans or advances. As of December 31, 2017, the amount ofthe restricted net assets, which represents registered capital and additional paid-in capital cumulative appropriations made to statutory reserves, wasUS$142.5 million. 101 As an offshore holding company, we are permitted, under PRC laws and regulations, to provide funding from the proceeds of our offshore fundraising activities to our PRC subsidiaries only through loans or capital contributions, and to our variable interest entity only through loans, subject to thesatisfaction of the applicable government registration and approval requirements. See “Item 3. Key Information—D. Risk factors—Risks related to ourcorporate structure—PRC regulation of loans to, and direct investment in, PRC entities by offshore holding companies and governmental control of currencyconversion may restrict or prevent us from making loans to our PRC subsidiaries and variable interest entity and its subsidiaries or making additional capitalcontributions to our PRC subsidiaries, which may materially and adversely affect our liquidity and our ability to fund and expand our business.” As a result,uncertainties exist as to our ability to provide prompt financial support to our PRC subsidiaries or variable interest entity when needed. Notwithstanding theforgoing, Giganology Shenzhen may use its own retained earnings (as opposed to RMB converted from foreign currency denominated capital) to providefinancial support to Shenzhen Xunlei either through extended payment terms on amounts due to Giganology Shenzhen from Shenzhen Xunlei, or viaentrusted loans from Giganology Shenzhen to Shenzhen Xunlei, or direct loans to its nominee shareholders, which would be contributed to the variableinterest entity as capital injection. Such direct loans to the nominee shareholders would be eliminated in the consolidated financial statements against theVIE’s share capital. We believe that our current cash and cash equivalents and anticipated cash flow from operations will be sufficient to meet our anticipated cash needsfor the next 12 months. We may, however, need additional cash resources in the future if we experience changes in business conditions or otherdevelopments. We may also need additional cash resources in the future if we find and wish to pursue opportunities for investment, acquisition, capitalexpenditure or similar actions. If we determine that our cash requirements exceed the amount of cash and cash equivalents we have on hand, we may seek toissue debt or equity securities or obtain additional credit facilities. The following table sets forth a summary of our cash flows for the periods indicated: For the Year Ended December 31, 2015 2016 2017 (in thousands of US$) Net cash generated from/(used in) operating activities 13,764 16,970 (14,216)Net cash generated from/(used in) investing activities (54,982) (158,335) 35,208 Net cash generated from/(used in) from financing activities 5,030 (11,041) 2,561 Net increase/(decrease) in cash and cash equivalents (36,188) (152,406) 23,553 Cash and cash equivalents at the beginning of year 404,275 361,777 199,504 Effect of exchange rates on cash and cash equivalents (6,310) (9,867) 10,422 Cash and cash equivalents at end of year 361,777 199,504 233,479 As of December 31, 2017, we had cash or cash equivalents of US$233.5 million in total, including RMB436.8 million (US$66.9 million) andUS$2.8 million located within the PRC, of which RMB313.9 million (US$48.0 million) was held by our VIE Shenzhen Xunlei and its subsidiaries.

Investing activities Net cash used in investing activities largely reflects purchases of property and equipment in connection with the expansion and upgrade of ourtechnology infrastructure, purchases of intangibles assets, acquisition of long-term investments and payments to purchase short-term investments such asequity interest in limited partnerships that make venture capital investments on companies with enterprise technologies, next generation hardware andrelated technologies. Net cash generated from investing activities amounted to US$35.2 million in 2017, primarily attributable to proceeds from disposal of short-terminvestments of US$291.6 million, partially offset by purchase of short-term investment of US$244.8 million.

In the past, our capital expenditures were primarily used to purchase servers or other equipment for our business and pay for constructionin progress. Our capital expenditures may increase in the near term as our business continues to grow. C.Research and Development We believe that our commitment to research and development is an important contributing factor in our success. As of December 31, 2017, we had ateam of 620 engineers.

Except for the registration rights, all preferred shareholders’ rights automatically terminated upon thecompletion of our initial public offering. Additionally, the co-founders have agreed to the transfer restrictions imposed on an aggregate number of39,934,162 common shares beneficially owned by the co-founders. Accordingly, the co-founders are unable to transfer the relevant shares to any third partyuntil April 24, 2019 or April 24, 2018, as the case may be. Pursuant to our seventh amended and restated shareholders agreement, we have granted certain registration rights to our shareholders. Theregistration rights remain effective as of the date of this annual report. Set forth below is a description of the registration rights granted under the agreement. Demand registration rights. At any time following the completion of initial public offering, upon a written request from the holders of at least 30%of the registrable securities then outstanding, we shall file a registration statement covering the offer and sale of the registrable securities. Registrablesecurities include our common shares issued or issuable upon conversion of the preferred shares provided that, with respect to demand registration right,registrable securities exclude common shares issued or issuable upon conversion of the series C preferred shares. However, we are not obligated to proceedwith a demand registration if (i) such registration is in any particular jurisdiction in which we would be required to execute a general consent to service ofprocess in effecting such registration, qualification or compliance, unless we already are subject to service in such jurisdiction and except as may be requiredby the Securities Act; (ii) we have already effected three demand registrations; (iii) such registration is during the period starting with the date 60 days priorto our good faith estimate of the date of filing of, and ending on a date 180 days after the effective date of a registration initiated by us, provided that we areactively employing in good faith all reasonable efforts to cause such registration statements to become effective; (iv) the initiating holders (defined in theshareholders agreement) propose to dispose of registrable securities which may be immediately registered on Form F-3 pursuant to a request from otherholders of registrable shares; (v) initiating holders do not request that such offering be firmly underwritten by underwriters selected by the initiating holdersor (vi) if we and the initiating holders are unable to obtain the commitment of the underwriter described in clause (v) above to firmly underwrite the offer.

Piggyback registration rights. If we propose to file a registration statement for a public offering of our securities other than pursuant to registrationstatement relating to any employee benefit plan or a corporate reorganization, then we must offer holders of registrable securities an opportunity to include inthat registration all or any part of their registrable securities. The underwriters of any underwritten offering have the right to limit the number of shares withregistration rights to be included in the registration statement, subject to certain limitations; for example, the number of shares that may be included in theregistration and the underwriting shall be allocated first to us and then to the series E, series D, series C, series B and series A-1 preferred shareholders in turn. Form F-3 registration rights. When we are eligible for registration on Form F-3, holders of at least 30% of the registrable securities then outstandingwill have the right to request that we file registration statements on Form F-3 covering the offer and sale of their securities. A Form F-3 registration shall notbe deemed to be a demand registration. We are not obligated to effect a Form F-3 registration, among other things, if (1) we have already effected a registration under the Securities Actwithin the six months period preceding the date of such request, other than a registration from which the registrable securities of the holders have beenexcluded, or (2) the dollar amount of securities to be sold is of an aggregate price to the public of less than US$1.0 million. We have the right to defer filingof a registration statement for up to 90 days if our board of directors determines in good faith that the filing of a registration statement would be materiallydetrimental to us, but we cannot exercise the deferral right more than once in any 12-month period. Expenses of registration. We will pay all expenses relating to any demand, piggyback, or Form F-3 registration, other than underwritingcommissions and discounts. 116 Termination of obligations.

As of the December 31, 2017, the advances to Mr. Shenglong Zou and Mr. Chuan Wang remainoutstanding. Game sharing arrangement with Zhuhai Qianyou Technology, Co., Ltd. In November 2011, we obtained an exclusive game operation right from Zhuhai Qianyou Technology, Co., Ltd., or Zhuhai Qianyou, our equityinvestee, which is specialized in developing online games. According to the agreement in relation to such game operation right that we entered into withZhuhai Qianyou, we need to share revenues derived by the licensed games with Zhuhai Qianyou. For the years ended December 31, 2015, 2016 and 2017,game sharing cost paid and payable to Zhuhai Qianyou was US$0.1 million, US$0.2 million and US$0.1 million, respectively. As of December 31, 2015,2016 and 2017, less than US$0.1 million, less than US$0.1 million and less than US$0.01 million, respectively, of the game sharing cost we owe to ZhuhaiQianyou remained unpaid and outstanding.

Item 8.Financial Information A.Consolidated Statements and Other Financial Information We have appended consolidated financial statements filed as part of this annual report. 118 Legal Proceedings We have been involved in legal proceedings related to our business from time to time and expect to continue to be involved in such proceedings inthe future. Internet services and content providers such as ours are frequently involved in litigation based on intellectual property-related claims. See “Item 3.Key Information—D. Risk factors—Risks related to our business—We face and expect to continue to face copyright infringement claims and other relatedclaims, including claims based on content available through our services, which could be time-consuming and costly to defend and may result in damageawards, injunctive relief and/or court orders, divert our management’s attention and financial resources and adversely impact our business.” We were subject to a number of lawsuits in China for alleged copyright infringements over the years, a number of which are still outstanding as ofthe date of this annual report. In addition, two putative shareholder class action lawsuits have been filed in the United States District Courts for the SouthernDistrict of New York against our Company and certain current and former officers and directors of our Company: Dookeran v. Xunlei Limited, et al. (filed onJanuary 18, 2018, Case No. 18-cv-467 (S.D.N.Y.)), and Peng Li v. Xunlei Limited, et al. (filed on January 24, 2018, Case No. 18-cv-646 (S.D.N.Y.)). Purportingto sue on behalf of all investors who purchased or acquired Xunlei stock from October 10, 2017 to January 11, 2018, plaintiffs allege that certain statementsregarding OneCoin in the Company’s press releases and on a quarterly investor call were false and misleading because, among other things, they failed todisclose that OneCoin was a disguised “initial coin offering” and “initial miner offering” and constituted “unlawful financial activity.” Plaintiffs seek torecover 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 theactions under the caption In re Xunlei Limited Securities Litigation, No. 18-cv-467 (RJS), and appointed lead plaintiffs and lead plaintiffs’ counsel. Theproceedings are still at an early stage, and the consolidated amended complaint has not yet been filed. Although legal proceedings are inherently uncertain and their results cannot be predicted, we have not been, nor are we currently a party to or awareof, any legal proceeding, investigation or claim that, in the view of our management, is likely to materially and adversely affect our business, financialposition or results of operations. Dividend Policy We have not previously declared or paid cash dividends. Subject to our ongoing financial performance, cash position, budget and business plan andmarket conditions, we may consider paying special dividends. However, we do not plan to pay dividends in the foreseeable future We currently intend toretain most, if not all, of our available funds and any future earnings to operate and expand our business. We are a holding company incorporated in the Cayman Islands. We rely principally on dividends from our subsidiaries in China for our cashrequirements, including any payment of dividends to our shareholders. PRC regulations may restrict the ability of our PRC subsidiaries to pay dividends tous. See “Item 4. Information on the Company—B. Business Overview—Regulation—Regulation on dividend distributions.” Our board of directors has discretion as to whether to distribute dividends, subject to applicable laws. Our shareholders may by ordinary resolutiondeclare dividends, but no dividend may exceed the amount recommended by our board of directors. Even if our board of directors decides to pay dividends,the form, frequency and amount will depend upon our future operations and earnings, capital requirements and surplus, general financial condition,contractual restrictions and other factors that the board of directors may deem relevant. Under Cayman Islands law, we may declare and pay dividends on ourshares only out of our profit or our share premium account, provided always that even if our company has sufficient profit or share premium, we may not pay adividend if this would result in our company being unable to pay our debts as they fall due in the ordinary course of business. If we pay any dividends on ourcommon shares, we will pay those dividends which are payable in respect of the common shares underlying our ADSs to the depositary, as the registeredholder of such common shares, and the depositary then will pay such amounts to our ADS holders in proportion to the common shares underlying the ADSsheld by such ADS holders, subject to the terms of the deposit agreement, including the fees and expenses payable thereunder. See “Item 12. Description ofSecurities Other than Equity Securities—D. American Depositary Shares.” Cash dividends on our common shares, if any, will be paid in U.S. dollars. 119 B.Significant Changes Except as disclosed elsewhere in this annual report, we have not experienced any significant changes since the date of our audited consolidatedfinancial statements included in this annual report.

Information on the Company—Business Overview—Regulation— Regulation on foreign exchange control and administration.” E.Taxation Cayman Islands Taxation According to Maples and Calder (Hong Kong) LLP, our Cayman Islands legal counsel, the Cayman Islands currently levies no taxes on individualsor corporations based upon profits, income, gains or appreciation and there is no taxation in the nature of inheritance tax or estate duty. There are no othertaxes likely to be material to us levied by the Government of the Cayman Islands except for stamp duties which may be applicable on instruments executedin, or after execution brought within, the jurisdiction of the Cayman Islands. The Cayman Islands is not party to any double tax treaties that are applicable toany payments made to or by our company. There are no exchange control regulations or currency restrictions in the Cayman Islands. People’s Republic of China Taxation Under the PRC EIT Law, an enterprise established outside the PRC with “de facto management bodies” within the PRC is considered a “residententerprise” of the PRC. A circular issued by the SAT on April 22, 2009 clarified that dividends and other income paid by such resident enterprises will beconsidered PRC-source income and subject to PRC withholding tax, currently at a rate of 10%, when paid to non-PRC enterprise shareholders. Under theimplementation regulations to the EIT Law, a “de facto management body” is defined as a body that has material and overall management and control overthe manufacturing and business operations, personnel and human resources, finances and properties of an enterprise. In addition, the circular mentionedabove specifies that certain offshore enterprises controlled by PRC resident enterprises will be classified as PRC resident enterprises if the following arelocated or resident in the PRC: senior management personnel and departments that are responsible for daily production, operation and management; financialand personnel decision making bodies; key properties, accounting books, the company seal, and minutes of board meetings and shareholders’ meetings; andhalf or more of the senior management or directors having voting rights. We do not believe we would be treated as a “resident enterprise” for PRC taxpurposes even if the criteria for “de facto management body” as set forth in the circular mentioned above were deemed applicable to us. See “Item 3. KeyInformation—D. Risk factors—Risks related to doing business in China—Our global income may be subject to PRC taxes under the PRC EIT Law, whichmay have a material adverse effect on our results of operations.” However, if the PRC tax authorities determine that we are a PRC resident enterprise forenterprise income tax purposes, we may be required to withhold a 10% withholding tax from dividends we pay to our non-resident enterprise shareholders,including the holders of our ADSs and non-resident enterprise holders may be subject to PRC tax on gains realized on the sale or other disposition of ADSs orcommon shares. It is unclear whether our non-PRC individual shareholders (including our ADS holders) would be subject to any PRC tax on dividends orgains in the event we are determined to be a PRC resident enterprise. If any PRC tax were to apply to such dividends or gains, it would generally apply at arate of 20% (unless a reduced rate is available under an applicable tax treaty). 121 If we are deemed to be a PRC resident enterprise and our non-resident enterprise shareholders (including our ADS holders) are subject to PRC tax asdescribed above, the withholding agent will be required to withhold enterprise income tax on payments of dividends to such investors. The withholdingagent must obtain a tax withholding registration and withhold the enterprise income tax from each payment made to non-resident enterprise shareholders andfile a report to the competent tax authorities. Where the withholding agent fails or is unable to perform its withholding obligation, the non-resident enterpriseshareholders must pay the tax due to the applicable tax authorities within seven days after the payment is made or due. We, as the withholding agent, will berequired to obtain a tax withholding registration and withhold the applicable enterprise income tax in order to comply with the above requirements. It is notclear who the withholding agent would be if tax is due on capital gains. In the event that we or our non-resident enterprise shareholders (including our ADSholders) fail to comply with the above procedures, we or our non-resident enterprise shareholders (including our ADS holders) may be ordered to rectify thenon-compliance or be subject to a fine of no more than RMB10,000. Failure by us to withhold the income tax fully and timely may result in a fine of 50% tothree times of the unpaid tax and failure by our ADS holders to pay the tax fully and timely may result in late payment penalties, or a fine of 50% to threetimes of the unpaid tax. In addition, if we are treated as a PRC resident enterprise for enterprise income tax purposes, we may be eligible for the benefits of the income taxtreaty between the PRC and other jurisdictions in which we may derive income, such as the United States. However, if we are treated as a PRC residententerprise, we do not expect to withhold at treaty rates if any withholding is required on dividends we pay to our non-resident shareholders (including ourADS holders) notwithstanding such holders may be eligible for the income tax treaty between their resident jurisdictions and the PRC. The United States—PRC tax treaty generally limits PRC withholding on dividends to a rate of 10%. Investors should consult their tax advisors regarding the availability of treatybenefits and the procedure for claiming a refund, if any. If we are not deemed a PRC resident enterprise, no PRC income tax will be withheld from dividends distributed by us and no PRC income tax will bepayable on gains realized from the sale or other disposition of our shares or ADSs by the non-resident holders of our shares or ADSs. SAT Circular 7 furtherclarifies that, where a non-resident enterprise derives income by acquiring and selling shares in an offshore listed enterprise in the public market, such incomeshall not be subject to PRC tax. However, given the uncertainty concerning the application of SAT Public Notice 37 and SAT Circular 7, we and our non-PRC resident investors may be at risk of being required to file a return and being taxed under SAT Public Notice 37 and SAT Circular 7, and we may berequired to expend valuable resources to comply with SAT Public Notice 37 and SAT Circular 7 or to establish that we should not be taxed under SAT PublicNotice 37 and SAT Circular 7 in the future. United States Federal Income Tax Considerations The following discussion is a summary of the United States federal income tax considerations relating to the ownership and disposition of our ADSsor common shares by a U.S. Holder (as defined below) that holds our ADSs as “capital assets” (generally, property held for investment) under the UnitedStates Internal Revenue Code of 1986, as amended, or the Code. This discussion is based upon existing United States federal income tax law, which is subjectto differing interpretations or change, possibly with retroactive effect. No ruling has been sought from the Internal Revenue Service (the “IRS”) with respectto any United States federal income tax consequences described below, and there can be no assurance that the IRS or a court will not take a contrary position.This discussion does not address all aspects of United States federal income taxation that may be important to particular investors in light of their individualinvestment circumstances, including investors subject to special tax rules (for example, certain financial institutions, banks, insurance companies, regulatedinvestment companies, real estate investment trusts, broker-dealers, traders in securities that elect mark-to-market treatment, partnerships and their partners,and tax-exempt organizations (including private foundations), holders who are not U.S. Holders, cooperatives, pension plans, U.S. expatriates, persons whoacquired ADSs or common shares pursuant to the exercise of any employee share option or otherwise as compensation, holders who own (directly, indirectlyor constructively) 10% or more of our stock, holders that hold their ADSs or common shares as part of a straddle, hedge, conversion, constructive sale or otherintegrated transaction, or holders that have a functional currency other than the United States dollar, all of whom may be subject to tax rules that differsignificantly from those summarized below). In addition, except to the extent described below, this discussion does not discuss any state, local, alternativeminimum tax, non-United States tax, non-income tax (such as gift or estate tax), or the Medicare tax considerations. U.S. Holders are urged to consult their taxadvisors regarding the United States federal, state, local, and non-United States income and other tax considerations relating to the ownership and dispositionof our ADSs or common shares. 122 General For purposes of this discussion, a “U.S. Holder” is a beneficial owner of our ADSs or common shares that is, for United States federal income taxpurposes, (i) an individual who is a citizen or resident of the United States, (ii) a corporation (or other entity treated as a corporation for United States federalincome tax purposes) created in, or organized under the laws of, the United States or any state thereof or the District of Columbia, (iii) an estate the income ofwhich is includible in gross income for United States federal income tax purposes regardless of its source, or (iv) a trust (A) the administration of which issubject to the primary supervision of a United States court and which has one or more United States persons who have the authority to control all substantialdecisions of the trust or (B) that has otherwise elected to be treated as a United States person under the Code. If a partnership (or other entity treated as a partnership for United States federal income tax purposes) is a beneficial owner of our ADSs or commonshares, the tax treatment of a partner in the partnership will generally depend upon the status of the partner and the activities of the partnership. Partnershipsholding our ADSs or common shares and partners in such partnerships are urged to consult their tax advisors regarding the ownership and disposition of ourADSs or common shares. It is generally expected that a holder of ADSs should be treated, for United States federal income tax purposes, as the beneficial owner of theunderlying shares represented by the ADSs. The remainder of this discussion assumes that a holder of ADSs will be treated in this manner. Accordingly,deposits or withdrawals of common shares for ADSs will generally not be subject to United States federal income tax. Passive Foreign Investment Company Considerations Based on the market price of our ADSs and the composition of assets (in particular, the retention of a large amount of cash), we believe that we werea passive foreign investment company (“PFIC”) for United States federal income tax purposes for the taxable year ended December 31, 2017, and we will verylikely be classified as a PFIC for our current taxable year ending December 31, 2018 unless the market price of our ADSs increases and/or we invest asubstantial amount of the cash and other passive assets we hold in assets that produce or are held for the production of non-passive income. A non-UnitedStates corporation, such as our company, will be classified as a “passive foreign investment company”, or “PFIC”, for United States federal income taxpurposes, if, in the case of any particular taxable year, either (i) 75% or more of its gross income for such year consists of certain types of “passive” income or(ii) 50% or more of the average quarterly value of its assets (as determined on the basis of fair market value) during such year produce or are held for theproduction of passive income. For this purpose, cash is categorized as a passive asset and the company’s unbooked intangibles associated with activebusiness activities may generally be classified as non-passive assets. Passive income generally includes, among other things, dividends, interest, rents,royalties, and gains from the disposition of passive assets. We will be treated as owning a proportionate share of the assets and earning a proportionate shareof the income of any other corporation in which we own, directly or indirectly, more than 25% (by value) of the stock. If we are classified as a PFIC for any year during which a U.S. Holder holds our ADSs or common shares, we generally will continue to be treated as aPFIC for all succeeding years during which such U.S. Holder holds our ADSs or common shares even if we cease to meet the threshold requirements for PFICstatus, unless a U.S. Holder makes a taxable “deemed sale” election that may allow the U.S. Holder to eliminate the continuing PFIC status under certaincircumstances. The United States federal income tax rules that apply if we are classified as a PFIC for our current or future taxable years are generally discussedbelow under “Passive foreign investment company rules.” 123 Dividends Subject to the discussion below under “Passive foreign investment company rules,” any cash distributions (including the amount of any PRC taxwithheld) paid on our ADSs or common shares out of our current or accumulated earnings and profits, as determined under United States federal income taxprinciples, will generally be includible in the gross income of a U.S. Holder as dividend income on the day actually or constructively received by the U.S.Holder, in the case of common shares, or by the depositary, in the case of ADSs. Because we do not intend to determine our earnings and profits on the basisof United States federal income tax principles, any distribution paid will generally be treated as a “dividend” for United States federal income tax purposes. Anon-corporate recipient of dividend income will generally be subject to tax on dividend income from a “qualified foreign corporation” at a lower applicablecapital gains rate rather than the marginal tax rates generally applicable to ordinary income provided that certain holding period requirements are met. A non-United States corporation (other than a corporation that is classified as a PFIC for the taxable year in which the dividend is paid or the preceding taxable year)generally will be considered to be a qualified foreign corporation (i) if it is eligible for the benefits of a comprehensive tax treaty with the United States whichthe Secretary of Treasury of the United States determines is satisfactory for purposes of this provision and which includes an exchange of informationprogram, or (ii) with respect to any dividend it pays on stock (or ADSs in respect of such stock) which is readily tradable on an established securities marketin the United States. Our ADSs are currently listed on the NASDAQ Global Select Market. We believe that the ADSs will be readily tradable on an establishedsecurities market in the United States for so long as our ADSs continue to be listed on the NASDAQ Global Select Market. Since we do not expect that ourcommon shares will be listed on established securities markets, it is unclear whether dividends that we pay on our common shares that are not backed byADSs currently meet the conditions required for the reduced tax rate. There can be no assurance that our ADSs will continue to be considered readily tradableon an established securities market in later years. Furthermore, as mentioned above, we believe that we were a PFIC for the taxable year ended December 31,2017, and we will very likely be classified as a PFIC for our current taxable year ending December 31, 2018. Each non-corporate U.S. Holder is advised toconsult their tax advisors regarding the availability of the lower capital gains rate applicable to qualified dividend income for any dividends we pay withrespect to the common shares and ADSs. Dividends received on our ADSs or common shares will not be eligible for the dividends received deduction allowedto corporations. Dividends will generally be treated as passive income from foreign sources for United States foreign tax credit purposes. A U.S. Holder may beeligible, subject to a number of complex limitations, to claim a foreign tax credit in respect of any foreign withholding taxes imposed on dividends receivedon our ADSs or common shares. The rules governing the foreign tax credit are complex. U.S. Holders are urged to consult their tax advisors regarding theavailability of the foreign tax credit under their particular circumstances. A U.S. Holder who does not elect to claim a foreign tax credit for foreign taxwithheld, may instead claim a deduction, for United States federal income tax purposes, in respect of such withholding, but only for a year in which suchholder elects to do so for all creditable foreign income taxes. Sale or Other Disposition of ADSs or Common Shares Subject to the discussion below under “Passive foreign investment company rules,” a U.S. Holder will generally recognize capital gain or loss uponthe sale or other disposition of ADSs or common shares in an amount equal to the difference between the amount realized upon the disposition and theholder’s adjusted tax basis in such ADSs or common shares. Any capital gain or loss will be long-term if the ADSs or common shares have been held for morethan one year and will generally be United States source gain or loss for United States foreign tax credit purposes. Long-term capital gain of non-corporateU.S. Holders is generally eligible for a reduced rate of taxation. The deductibility of a capital loss is subject to limitations. In the event that gain from thedisposition of the ADSs or common shares is subject to tax in the PRC, a U.S. Holder that is eligible for the benefits of the income tax treaty between theUnited States and the PRC may elect to treat the gain as PRC source income. U.S. Holders are advised to consult its tax advisors regarding the taxconsequences if a PRC tax is imposed on a disposition of our ADSs or common shares, including the availability of the foreign tax credit under theirparticular circumstances. Passive Foreign Investment Company Rules As mentioned above, we believe that we were a PFIC for the taxable year ended December 31, 2017, and we will very likely be classified as a PFICfor our current taxable year ending December 31, 2018. If we are classified as a PFIC for any taxable year during which a U.S. Holder holds our ADSs orcommon shares, and unless the U.S. Holder makes a mark-to-market election (as described below), the U.S. Holder will generally be subject to special UnitedStates federal income tax rules that have a penalizing effect, regardless of whether we remain a PFIC, on (i) any excess distribution that we make to the U.S.Holder (which generally means any distribution paid during a taxable year to a U.S. Holder that is greater than 125 percent of the average annualdistributions paid in the three preceding taxable years or, if shorter, the U.S. Holder’s holding period for the ADSs or common shares), and (ii) any gainrealized on the sale or other disposition, including, under certain circumstance, a pledge, of ADSs or common shares. Under the PFIC rules: 124 ·the excess distribution and/or gain will be allocated ratably over the U.S. Holder’s holding period for the ADSs or common shares; ·the amount allocated to the current taxable year and any taxable years in the U.S. Holder’s holding period prior to the first taxable year in whichwe are classified as a PFIC, or a pre-PFIC year, will be taxable as ordinary income; ·the amount allocated to each prior taxable year, other than a pre-PFIC year, will be subject to tax at the highest tax rate in effect applicable tothe U.S. Holder for that year; and ·an interest charge generally applicable to underpayments of tax will be imposed on the tax attributable to each prior taxable year, other than apre-PFIC year. If we are a PFIC for any taxable year during which a U.S. Holder holds our ADSs or common shares and any of our non-United States subsidiaries orVIE entities is also a PFIC, such U.S. Holder would be treated as owning a proportionate amount (by value) of the shares of the lower-tier PFIC for purposes ofthe application of these rules. U.S. Holders are advised to consult their tax advisors regarding the application of the PFIC rules to any of our subsidiaries orVIE entities. As an alternative to the foregoing rules, a U.S. Holder of “marketable stock” in a PFIC may make a mark-to-market election with respect to our ADSs,provided that the ADSs are regularly traded on the NASDAQ Global Select Market. In addition, we do not expect that holders of common shares that are notrepresented by ADSs will be eligible to make a mark-to-market election. Our ADSs may be regularly traded, but no assurances may be given in this regard. If amark-to-market election is made, the U.S. Holder will generally (i) include as ordinary income for each taxable year that we are a PFIC the excess, if any, ofthe fair market value of ADSs held at the end of the taxable year over the adjusted tax basis of such ADSs and (ii) deduct as an ordinary loss the excess, if any,of the adjusted tax basis of the ADSs over the fair market value of such ADSs held at the end of the taxable year, but only to the extent of the net amountpreviously included in income as a result of the mark-to-market election. The U.S. Holder’s adjusted tax basis in the ADSs would be adjusted to reflect anyincome or loss resulting from the mark-to-market election. If a U.S. Holder makes an effective mark-to-market election, in each year that we are a PFIC anygain recognized upon the sale or other disposition of the ADSs will be treated as ordinary income and loss will be treated as ordinary loss, but only to theextent of the net amount previously included in income as a result of the mark-to-market election. Because a mark-to-market election cannot be made for any lower-tier PFICs that we may own, a U.S. Holder that makes a mark-to-market electionwith respect to our ADSs may continue to be subject to the general PFIC rules with respect to such U.S. Holder’s indirect interest in any investments held byus that are treated as an equity interest in a PFIC for United States federal income tax purposes. We do not intend to provide information necessary for U.S. Holders to make qualified electing fund elections, which, if available, would result in taxtreatment different from (and generally less adverse than) the general tax treatment for PFICs described above. If a U.S. Holder owns our ADSs or common shares during any taxable year that we are a PFIC, the holder generally will be required to file annualreports with the IRS. U.S. Holders are advised to consult their tax advisors concerning the United States federal income tax consequences of purchasing,holding and disposing ADSs or common shares if we are or become classified as a PFIC, including the possibility of making a mark-to-market election. 125 Information Reporting U.S. Holders may be subject to information reporting to the IRS with respect to dividends on and proceeds from the sale or other disposition of ourADSs or common shares. Each U.S. Holder is advised to consult its tax advisors regarding the application of the United States information reporting rules toits particular circumstances. Certain U.S. Holders who hold “specified foreign financial assets”, including stock of a non-U.S. corporation that is not held in an accountmaintained by a U.S. “financial institution,” whose aggregate value exceeds US$50,000 during the tax year, may be required to attach to their tax returns forthe year certain specified information. An individual who fails to timely furnish the required information may be subject to a penalty. U.S. Holders who areindividuals should consult their own tax advisors regarding their reporting obligations under this legislation. F.Dividends and Paying Agents Not applicable. G.Statement by Experts Not applicable. H.Documents on Display We are subject to the periodic reporting and other informational requirements of the Exchange Act. Under the Exchange Act, we are required to filereports and other information with the SEC. Specifically, we are required to file annually a Form 20-F within four months after the end of each fiscal year,which is December 31. Copies of reports and other information, when so filed, may be inspected without charge and may be obtained at prescribed rates at thepublic reference facilities maintained by the SEC at 100 F Street, N.E., Room 1580, Washington, D.C. 20549. The public may obtain information regardingthe Washington, D.C. Public Reference Room by calling the Commission at 1-800-SEC-0330. The SEC also maintains a website at www.sec.gov thatcontains reports, proxy and information statements, and other information regarding registrants that make electronic filings with the SEC using its EDGARsystem. As a foreign private issuer, we are exempt from the rules under the Exchange Act prescribing the furnishing and content of quarterly reports and proxystatements, and officers, directors and principal shareholders are exempt from the reporting and short-swing profit recovery provisions contained in Section16 of the Exchange Act. We will furnish The Bank of New York Mellon, the depositary of our ADSs, with our annual reports, which will include a review of operations andannual audited consolidated financial statements prepared in conformity with U.S. GAAP, and all notices of shareholders’ meetings and other reports andcommunications that are made generally available to our shareholders. The depositary will make such notices, reports and communications available toholders of ADSs and, upon our request, will mail to all record holders of ADSs the information contained in any notice of a shareholders’ meeting received bythe depositary from us. In accordance with NASDAQ Stock Market Rule 5250(d), we will post this annual report on Form 20-F on our website at http://ir.xunlei.com. Inaddition, we will provide hardcopies of our annual report free of charge to shareholders and ADS holders upon request. I.Subsidiary Information Not applicable. Item 11.Quantitative and Qualitative Disclosures about Market Risk Foreign exchange risk Our financing activities are denominated mainly in U.S. dollars. The Renminbi, or RMB, is not freely convertible into foreign currencies.Remittances of foreign currencies into the PRC and conversion of foreign currencies into RMB require approval by foreign exchange administrativeauthorities 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 our subsidiaries, and the consolidated VIE and its subsidiaries aregenerally denominated in RMB and their assets and liabilities are denominated in RMB. We do not believe that we currently have any significant directforeign exchange risk and have not used any derivative financial instruments to hedge our exposure to such risk. Although in general, our exposure toforeign exchange risks should be limited, the value of your investment in our ADSs will be affected by the exchange rate between the U.S. dollar and theRMB because the value of our business is effectively denominated in RMB, while the ADSs will be traded in U.S. dollars. 126 The conversion of RMB into foreign currencies, including U.S. dollars, is based on rates set by the People’s Bank of China. The PRC governmentallowed the RMB to appreciate by more than 20% against the U.S. dollar between July 2005 and July 2008. Between July 2008 and June 2010, thisappreciation halted and the exchange rate between the RMB and the U.S. dollar remained within a narrow band. Since June 2010, the RMB has fluctuatedagainst the U.S. dollar, at times significantly and unpredictably. It is difficult to predict how market forces or PRC or U.S. government policy may impact theexchange rate between the RMB and the U.S. dollar in the future. To the extent that we need to convert U.S. dollars into RMB for our operations, appreciation of the RMB against the U.S. dollar would have anadverse effect on the RMB amount we receive from the conversion. Conversely, if we decide to convert RMB into U.S. dollars for the purpose of makingpayments for dividends on our ordinary shares or ADSs or for other business purposes, appreciation of the U.S. dollar against the RMB would have a negativeeffect on the U.S. dollar amounts available to us. As of December 31, 2017, we had RMB-denominated cash and cash equivalents, restricted cash and short-term investments of RMB0.57 billion,HKD-denominated cash and cash equivalents, restricted cash and short-term investments of HKD0.79 million, and U.S. dollar-denominated cash, cashequivalents and short-term investments of US$0.29 billion. Assuming we had converted RMB0.57 billion into U.S. dollars at the exchange rate ofRMB6.5342 for US$1.00 as of December 29, 2017, our U.S. dollar cash balance would have been US$0.37 billion. If the RMB had depreciated by 10%against the U.S. dollar, our U.S. dollar cash balance would have been US$0.36 billion instead. Assuming we had converted US$0.29 billion into RMB at theexchange rate of RMB6.5342 for US$1.00 as of December 29, 2017, our RMB cash balance would have been RMB2.43 billion. If the RMB had depreciatedby 10% against the U.S. dollar, our RMB cash balance would have been RMB2.62 billion instead. Interest rate risk Our exposure to interest rate risk primarily relates to the interest income generated by excess cash, which is mostly held in interest-bearing bankdeposits. We have not used derivative financial instruments in our investment portfolio. Interest earning instruments carry a degree of interest rate risk. Wehave not been exposed to, nor do we anticipate being exposed to, material risks due to changes in market interest rates. However, our future interest incomemay fall short of expectations due to changes in market interest rates. Item 12.Description of Securities Other than Equity Securities A.Debt Securities Not applicable. B.Warrants and Rights Not applicable. C.Other Securities Not applicable. D.American Depositary Shares 127 Fees and Charges Our ADS holders May Have to Pay The Bank of New York Mellon, the depositary of our ADS program, collects its fees for delivery and surrender of ADSs directly from investorsdepositing shares or surrendering ADSs for the purpose of withdrawal or from intermediaries acting for them. The depositary collects fees for makingdistributions to investors by deducting those fees from the amounts distributed or by selling a portion of distributable property to pay the fees. Thedepositary may collect its annual fee for depositary services by deduction from cash distributions or by directly billing investors or by charging the book-entry system accounts of participants acting for them. The depositary may collect any of its fees by deduction from any cash distribution payable to ADSholders that are obligated to pay those fees. The depositary may generally refuse to provide fee-attracting services until its fees for those services are paid.The depositary’s corporate trust office at which the ADSs will be administered is located at 101 Barclay Street, New York, New York 10286. The depositary’sprincipal executive office is located at One Wall Street, New York, New York 10286. Persons depositing or withdrawing shares must pay: For:$5.00 (or less) per 100 ADSs (or portion of 100 ADSs) · Issuance of ADSs, including issuances resulting from a distribution ofshares or rights or other property · Cancellation of ADSs for the purpose of withdrawal, including if thedeposit agreement terminates$0.05 (or less) per ADS · Any cash distribution to ADS holdersA fee equivalent to the fee that would be payable if securities distributed toyou had been shares and the shares had been deposited for issuance of ADSs · Distribution of securities distributed to holders of deposited securitieswhich are distributed by the depositary to ADS holders$0.05 (or less) per ADSs per calendar year · Depositary servicesRegistration or transfer fees · Transfer and registration of shares on our share register to or from thename of the depositary or its agent when you deposit or withdraw sharesExpenses of the depositary · Cable, telex and facsimile transmissions (when expressly provided in thedeposit agreement) · converting foreign currency to U.S. dollarsTaxes and other governmental charges the depositary or the custodian hasto pay on any ADSs or shares underlying ADSs, such as stock transfer taxes,stamp duty or withholding taxes · As necessaryAny charges incurred by the depositary or its agents for servicing thedeposited securities · As necessary Fees and Other Payments Made by the Depositary to Us The depositary has agreed to reimburse us for our expenses incurred in connection with the establishment of our ADS facility including, investorrelations expenses, roadshow expenses, legal fees, stock exchange listing fees or any direct or indirect expenses incurred in connection with theestablishment of the facility. The depositary has also agreed to provide additional reimbursements to us based on the applicable performance indicatorsrelating to our ADS facility, including ADS issuance and cancellation fees, cash dividend fees and depositary servicing fees. In 2017, we receivedapproximately US$0.13 million (after withholding tax) from the depositary. PART II Item 13.Defaults, Dividend Arrearages and Delinquencies None. Item 14.Material Modifications to the Rights of Security Holders and Use of Proceeds Material Modifications to the Rights of Security Holders None. 128 Use of Proceeds The following “Use of Proceeds” information relates to our initial public offering of 7,315,000 ADSs representing 36,575,000 of our common shares,and the underwriters’ full exercise of their option to purchase from us an additional 1,097,250 ADSs representing 5,486,250 common shares, at an initialoffering price of US$12.00 per ADS. Our initial public offering closed in June 2014. The total expenses incurred for our company’s account in connection with our initial public offering, including the over-allotment option, wereapproximately US$11.3 million, including underwriting discounts and commissions of approximately US$7.1 million, and other related costs of US$4.2million. None of the fees and expenses were directly or indirectly paid to the directors, officers, general partners of our company or their associates, personsowning 10% or more of our common shares, or our affiliates. After deducting the total expenses, we received net proceeds of approximately US$90.4 million from our initial public offering. As of December 31,2017, the net proceeds received from our initial public offering had been used for the following purposes: ·Approximately US$57.2 million to invest in technology, infrastructure and product development efforts; ·Approximately US$25.3 million to acquire digital media content and exclusive online game licenses; and ·Approximately US$7.9 million for other general corporate purposes, including working capital needs and potential acquisitions. None of the net proceeds from our initial public offering were directly or indirectly paid to the directors, officers, general partners of our company ortheir associates, persons owning 10% or more of our common shares, or our affiliates. Item 15.Controls and Procedures Evaluation of Disclosure Controls and Procedures Our management, with the participation of our chief executive officer and chief financial officer, has performed an evaluation of the effectiveness ofour disclosure controls and procedures (as defined in Rule 13a-15(e) under the Exchange Act) as of the end of the period covered by this report, as requiredby Rule 13a-15(b) under the Exchange Act. Based upon that evaluation, our management, with the participation of our chief executive officer and chief financial officer, has concluded that,due to the outstanding material weakness described below, as of December 31, 2017, our disclosure controls and procedures were not effective in ensuringthat the information required to be disclosed by us in the reports that we file and furnish under the Exchange Act was recorded, processed, summarized andreported, within the time periods specified in the SEC’s rules and forms, and that the information required to be disclosed by us in the reports that we file orsubmit under the Exchange Act is accumulated and communicated to our management, including our chief executive officer and chief financial officer, asappropriate, to allow timely decisions regarding required disclosure. Management’s Annual Report on Internal Control over Financial Reporting Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Rule13a-15(f) under the Exchange Act, for our Company. Internal control over financial reporting is a process designed to provide reasonable assurance regardingthe reliability of financial reporting and the preparation of consolidated financial statements in accordance with generally accepted accounting principles,including those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactionsand dispositions of a company’s assets, (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of consolidatedfinancial statements in accordance with generally accepted accounting principles, and that a company’s receipts and expenditures are being made only inaccordance with authorizations of a company’s management and directors, and (iii) provide reasonable assurance regarding prevention or timely detection ofunauthorized acquisition, use, or disposition of a company’s assets that could have a material effect on the consolidated financial statements. 129 Because of its inherent limitations, a system of internal control over financial reporting can provide only reasonable assurance with respect toconsolidated financial statement preparation and presentation and may not prevent or detect misstatements. Also, projections of any evaluation ofeffectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliancewith the policies or procedures may deteriorate. As required by Section 404 of the Sarbanes-Oxley Act of 2002 and related rules promulgated by the Securities and Exchange Commission, ourmanagement, including our chief executive officer and chief financial officer, assessed the effectiveness of internal control over financial reporting as ofDecember 31, 2017 using the criteria set forth in the report “Internal Control — Integrated Framework (2013)” published by the Committee of SponsoringOrganizations of the Treadway Commission (known as COSO). One material weakness in internal control over financial reporting has been identified as ofDecember 31, 2014 and 2015 and had not been remediated as of December 31, 2017. A material weakness is a deficiency, or a combination of deficiencies, ininternal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the company’s annual or interim financialstatements will not be prevented or detected on a timely basis. The material weakness identified is related to a lack of accounting resources in U.S. GAAP and SEC reporting requirements. Because of the materialweakness described above, our management has concluded that we did not maintain effective internal control over financial reporting as of December 31,2017, based on criteria established in Internal Control — Integrated Framework (2013) issued by COSO. Attestation Report of the Registered Public Accounting Firm This annual report on Form 20-F does not include an attestation report of the company’s independent registered public accounting firm because thecompany qualified as an “emerging growth company” as defined under the JOBS Act as of December 31, 2017. Changes in Internal Control over Financial Reporting In preparing our consolidated financial statements, we and our independent registered public accounting firm identified one material weakness, onesignificant deficiency and other control deficiencies in our internal control over financial reporting as of December 31, 2014 and December 31, 2015, whichhad not yet been remediated as of December 31, 2017. As defined in standards established by the PCAOB, a “material weakness” is a deficiency, orcombination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the annualor interim financial statements will not be prevented or detected on a timely basis. The material weakness identified was related to a lack of accounting resources in U.S. GAAP and SEC reporting requirements, and the significantdeficiency identified was related to a lack of documented comprehensive U.S. GAAP accounting manuals and financial reporting procedures and lack ofrelated implementation controls. To remediate our identified material weakness, significant deficiency and other control deficiencies in connection with preparation of ourconsolidated financial statements, we have adopted a number of measures to improve our internal control over financial reporting. For example, we hired achief financial officer and a senior financial officer, each of whom has a solid understanding of and extensive work experience involving U.S. GAAP and SECfinancial reporting. We engaged an external consulting firm to assist us to assess Sarbanes-Oxley compliance readiness and improve overall internal controls.In 2017, we provided our accounting and finance staff with U.S. GAAP training and knowledge sharing, and enhanced our accounting and manual withrespect to U.S. GAAP and SEC financial reporting requirements. We will continue to provide our accounting and finance staff with U.S. GAAP trainingregularly, enhance our accounting manual to provide our accounting team with more comprehensive guidelines on the accounting policies under U.S. GAAP,SEC rules and requirements, and we will continue to review and improve key controls over financial reporting. As such remedial measures had not been fullyimplemented in the limited time that elapsed since our initial public offering, our management concluded that the material weakness had not beenremediated as of December 31, 2017. We still lacked sufficient financial reporting and accounting personnel to formalize key controls over financialreporting and to timely and properly prepare and review financial statements and related footnote disclosures based on U.S. GAAP and SEC reportingrequirements. We are fully committed to continue to implement measures to remediate our material weakness, significant deficiency and other controldeficiencies in our internal control over financial reporting. However, the implementation of these measures may not fully address the deficiencies in ourinternal control over financial reporting. We are not able to estimate with reasonable certainty the costs that we will need to incur to implement these andother measures designed to improve our internal control over financial reporting. See “Item 3. Key Information—D. Risk factors—Risks related to ourbusiness and industry—If we fail to implement and maintain an effective system of internal control over financial reporting, we may be unable to accuratelyreport our financial results or prevent fraud or fail to meet our reporting obligations, and investor confidence in our company and the market price of ourADSs may be adversely affected.” 130 Other than as described above, no changes in our internal controls over financial reporting occurred during the period covered by this annual reportthat have materially affected, or are reasonably likely to materially affect, our internal controls over financial reporting. Item 16A.Audit Committee Financial Expert Our board of directors has determined that each of Ms. Jenny Wenjie Wu and Mr. Ya Li, our independent directors (under the standards set forth inRule 5605(a)(2) of the NASDAQ Listing Rules and Rule 10A-3 under the Securities Exchange Act of 1934) and chairman of our audit committee, is an auditcommittee financial expert.

Item 16E.Purchases of Equity Securities by the Issuer and Affiliated Purchasers In December 2014, our board of directors authorized a share repurchase program, or the Repurchase Program, whereby our company may repurchaseup to US$20 million of our common shares or ADSs from December 22, 2014 to December 31, 2015. The share repurchases may be made in accordance withapplicable laws and regulations through open market transactions, privately negotiated transactions or other legally permissible means as determined by ourmanagement, including through Rule 10b5-1 share repurchase plans. We publicly announced the Repurchase Program on December 22, 2014. The following table is a summary of the shares repurchased by us during 2015 under the Repurchase Program. No shares were repurchased during2015 except during the month indicated and all shares were purchased from our employees pursuant to the Repurchase Program.

Item 16G.Corporate Governance As a Cayman Islands company listed on the NASDAQ Global Select Market, we are subject to the corporate governance standards under theNASDAQ Stock Market Rules. Under Nasdaq Stock Market Rule 5615(a)(3), a foreign private issuer such as us may follow its home-country corporategovernance practices in lieu of certain of the Nasdaq Stock Market Rules corporate governance requirements. We strive to comply with most of the Nasdaqcorporate governance practices to ensure a high standard of corporate governance. However, our current corporate governance practices differ from Nasdaqcorporate governance requirements for U.S. companies in certain respects, as summarized below: Nasdaq Marketplace Rule 5620(a) requires each issuer to hold an annual meeting of shareholders no later than one year after the end of the issuer’sfiscal year-end. The practices of our home country, the Cayman Islands, do not require us to hold annual shareholders meetings every year. We have electedto adopt this practice and did not hold an annual meeting of shareholders for fiscal year 2017. We may, however, hold annual shareholders meeting in thefuture. Nasdaq Stock Market Rule 5605(b)(1) requires a Nasdaq-listed company to have a board of directors composed of at least a majority of independentdirectors. The practices of our home country, the Cayman Islands, do not require us to have a majority of the board of directors composed of independentdirectors at this time. We have elected to adopt this practice and do not have a board of directors composed of at least a majority of independent directors. Nasdaq Stock Market Rule 5605(c)(2) requires a Nasdaq-listed company to have an audit committee composed of at least three independentmembers. The practices of our home country, the Cayman Islands, do not require us to have a three member audit committee at this time. We have elected toadopt this practice and have an audit committee composed of two independent members. Nasdaq Stock Market Rule 5605(e)(1) requires a Nasdaq-listed company to have a nominations committee composed solely of independent directorsto select or recommend for selection director nominees. The practices of our home country, the Cayman Islands, do not require that any of the members of acompany’s nominations committee be independent directors. We have elected to adopt this practice and our corporate governance and nominatingcommittee is not composed solely of independent directors. Nasdaq Stock Market Rule 5605(d)(2) requires a Nasdaq-listed company to have a compensation committee composed solely of independentdirectors. The practices of our home country, the Cayman Islands, do not require that any of the members of a company’s compensation committee beindependent directors. We have elected to adopt this practice in order to utilize the experience of Mr. Chuan Wang and our compensation committee is notcomposed solely of independent directors. Maples and Calder (Hong Kong) LLP, our Cayman Islands counsel, has provided a letter to the NASDAQ Stock Market certifying that underCayman Islands law, we are not required to follow the above corporate governance standards. 133 Other than the above, there are no significant differences between our corporate governance practices and those followed by U.S. domesticcompanies under NASDAQ Stock Market Rules.

In our opinion, the consolidatedfinancial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2017 and 2016, and the results of theiroperations and their cash flows for each of the three years in the period ended December 31, 2017 in conformity with accounting principles generallyaccepted in the United States of America. Basis for Opinion These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’sconsolidated financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board(United States) (“PCAOB”) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and theapplicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audits of these consolidated financial statements in accordance with the standards of the PCAOB. Those standards require that we plan andperform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error orfraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits weare required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness ofthe Company's internal control over financial reporting. Accordingly, we express no such opinion. Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud,and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosuresin the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management,as well as evaluating the overall presentation of the consolidated financial statements.

While the Group’smanagement 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”) thatappears to include VIEs within the scope of entities that could be considered to be foreign invested enterprises (or “FIEs”) that would be subject torestrictions under existing PRC law on foreign investment in certain categories of industry. Specifically, the Draft FIE Law introduces the concept of “actualcontrol” 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 Lawincludes control through contractual arrangements within the definition of “actual control.” If the Draft FIE Law is passed by the People’s Congress of thePRC and goes into effect in its current form, these provisions regarding control through contractual arrangements could be construed to reach the Group’sVIE arrangements, and as a result the Group’s VIEs could become explicitly subject to the current restrictions on foreign investment in certain categories ofindustry. The Draft FIE Law includes provisions that would exempt from the definition of foreign invested enterprises entities where the ultimate controllingshareholders are either entities organized under PRC law or individuals who are PRC citizens. The Draft FIE Law does not make clear how “control” would bedetermined for such purpose, and is silent as to what type of enforcement action might be taken against existing VIEs that operate in restricted industries andare not controlled by entities organized under PRC law or individuals who are PRC citizens. If a finding were made by PRC authorities, under existing lawsand 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 sucha violation, including levying fines, confiscating the Group’s income, revoking the business or operating licenses of the affected businesses, requiring theGroup to restructure its ownership structure or operations, or requiring the Group to discontinue all or any portion of its operations. Any of these actionscould cause significant disruption to the Group’s business operations, and have a severe adverse impact on the Group’s cash flows, financial position andoperating 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 PRCgovernment authorities or courts were to find that such contracts contravene PRC law and regulations or are otherwise not enforceable for public policyreasons. In the event that the Group was unable to enforce these contractual arrangements, the Group would not be able to exert effective control over theaffected VIEs. Consequently, such VIE’s results of operations, assets and liabilities would not be included in the Group’s consolidated financial statements. Ifsuch were the case, the Group’s cash flows, financial position and operating performance would be severely adversely affected. The Group’s contractualarrangements with respect to its consolidated VIEs are approved and in place. The Group’s management believes that such contracts are enforceable, andconsiders the possibility remote that PRC regulatory authorities with jurisdiction over the Group’s operations and contractual relationships would find thecontracts to be unenforceable. F-14  Xunlei LimitedNotes to consolidated financial statements(Amounts in US dollars unless otherwise stated) 2.Summary of significant accounting policies (a)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 ofAmerica (‘‘U.S. GAAP’’). Significant accounting policies followed by the Group in the preparation of the accompanying consolidated financial statementsare summarized below. The Restructuring was accounted for at historical costs. The assets and liabilities of Shenzhen Xunlei are consolidated in the Company’s financial statementsat carryover basis. The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amountsreported 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, valuationallowance of deferred tax assets, sales rebate to advertising agencies, amortization period of online game revenue, amortization of content copyrights, fairvalue of content copyrights exchange, impairment assessment of goodwill and impairment assessment of long-lived assets. In addition, the Group usesassumptions 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 thebasis for making judgments about the carrying values of assets and liabilities. Actual results could differ from these estimates. (b)Consolidation The consolidated financial statements include the financial statements of the Company, its subsidiaries, VIE for which the Company is the primarybeneficiary and its subsidiaries. All significant transactions and balances among the Company, its subsidiaries, VIE and its subsidiaries have been eliminatedupon 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 removethe 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 operatingpolicies 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 sufficientequity 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 acontrolling financial interest or do not have sufficient equity at risk for the entity to finance its activities without additional subordinated financial supportfrom 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 directactivities that are significant to the VIE’s economic performance, including the power to appoint senior management, right to direct company strategy, powerto approve capital expenditure budgets, and power to establish and manage ordinary business operation procedures and internal regulations and systems. F-15  Xunlei LimitedNotes to consolidated financial statements(Amounts in US dollars unless otherwise stated) 2.Summary of significant accounting policies (Continued) (b)Consolidation (Continued) Management has evaluated the contractual arrangements among Giganology Shenzhen, Shenzhen Xunlei and its shareholders and concluded thatGiganology Shenzhen receives all of the economic benefits and absorbs all of the expected losses from Shenzhen Xunlei and has the power to direct theaforementioned 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 25 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 totalincome or loss for the year/period between non-controlling shareholders and the shareholders of the Company. (c)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 discontinuedoperations. 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 geographicallocation, line of business, or other significant part of the entity, or disposal of a major equity method investment. In the consolidated statement ofcomprehensive income, result from discontinued operations is reported separately from the income and expenses from continuing operations and priorperiods are presented on a comparative basis. Cash flows for discontinuing operations are presented separately in note 3. In order to present the financialeffects of the continuing operations and discontinued operations, revenues and expenses arising from intra-group transactions are eliminated except for thoserevenues and expenses that are considered to continue after the disposal of the discontinued operations. Non-current assets or disposal groups are classified as assets held for sale when the carrying amount is to be recovered principally through a sale transactionrather 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 subjectonly 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 heldfor sale and disposal groups are measured at the lower of their carrying or fair value less costs to sell. (d)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. Thefunctional 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 prevailingat the balance sheet date. The resulting exchange gains and losses from foreign currency transactions are included in other income (loss) within theconsolidated 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 andfinancial position, respectively, of its subsidiaries whose functional currency is other than the USD. The resulting translation differences are recorded incumulated translation adjustments, a component of shareholders’ equity. F-16  Xunlei LimitedNotes to consolidated financial statements(Amounts in US dollars unless otherwise stated) 2.Summary of significant accounting policies (Continued) (d)Foreign currency translation (Continued) The exchange rate used is released by Chinese State Administration of Foreign Exchange. (e)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 originalmaturities of three months or less and are readily convertible to known amounts of cash. (f)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 infinancial instruments with a variable interest rate indexed to the performance of underlying assets. In accordance with ASC 825 Financial Instruments, forinvestments in financial instruments with a variable interest rate indexed to performance of underlying assets, the Group elected the fair value method at thedate of initial recognition and carried these investments subsequently at fair value. Changes in the fair value are reflected in the consolidated statements ofcomprehensive 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. (g)Fair value of financial instruments The Group’s financial instruments consist principally of cash and cash equivalents, short-term investments, accounts receivable, other receivables, amountsdue from/(to) related parties, accounts payable, and other payables. The carrying value of these balances, with the exception of short-term investments (seenote 2 (f)), approximates their fair value due to the current and short term nature of these balances. (h)Accounts receivable, net Accounts receivable are presented net of allowance for doubtful accounts. The Group evaluates the creditworthiness of each customer at the time whenservices 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 isprobable 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 aregular 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, 2016 and 2017 were USD 119,000 and USD 31,000,respectively. F-17  Xunlei LimitedNotes to consolidated financial statements(Amounts in US dollars unless otherwise stated) 2.Summary of significant accounting policies (Continued) (h)Accounts receivable, net (Continued) If the Group determines that an allowance is needed for a customer, the Group will discontinue business with them unless they start to resume payment. Theaccounts receivable is written-off when the Group ceases pursuing collection. Any changes in the estimates may cause the Group's operating results tofluctuate. (i)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 theamount that can be realized from the sale of the inventory in the normal course of business after allowing for the costs of realization. An allowance is recorded for excess inventory and obsolescence based on the lower of cost or net realizable value. (j)Long-term investments The Group holds investments in privately held companies. The Group accounts for these investments over which it has significant influence but does notown a majority equity interest or otherwise control using the equity method of accounting. For investments in an investee over which the Group does nothave significant influence and of which the investee has no readily determinable fair value, the Group carries the investment using the cost method. Underthe cost method, the investment is measured initially at cost. The investment carried at cost should recognize income when dividends are received from thedistribution of the investee’s earnings. The Group assesses its long-term investments for other-than-temporary impairment by considering factors including,but not limited to, current economic and market conditions, operating performance of the companies, including current earnings trends and undiscountedcash flows, and other company-specific information. The fair value determination, particularly for investments in privately-held companies, requiressignificant judgment to determine appropriate estimates and assumptions. Changes in these estimates and assumptions could affect the calculation of the fairvalue of the investments and determination of whether any identified impairment is other-than-temporary. During the years ended December 31, 2015, 2016and 2017 the Group recognised an impairment of USD 0.8 million, USD 1.66 million and USD 0.6 million, respectively. During the year ended December 312017, the Group recognised share of loss of associate of USD 1.3 million for Big Data. (k)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 apercentage of the original cost. If the company 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. Estimated useful lives Residual rate Servers and network equipment 5 years 5%Computer equipment 5 years 5%Furniture, fittings and office equipment 5 years 5%Motor vehicles 5 years 5%Leasehold improvements shorter of lease term or 3 years — Repair and maintenance costs are expensed as incurred. Expenditures that substantially increase an asset’s useful life are capitalized. Upon sale ordisposition, gain or loss on the disposal of property and equipment is the difference between the net sales proceeds and the carrying amount of the relevantassets and is recognized in the consolidated statements of operations. The cost and related accumulated depreciation are removed from the financialstatements. F-18  Xunlei LimitedNotes to consolidated financial statements(Amounts in US dollars unless otherwise stated) 2.Summary of significant accounting policies (Continued) (l)Goodwill Goodwill represents the excess of the purchase consideration over the fair value of the identifiable tangible and intangible assets acquired and liabilitiesassumed from the acquired entity as a result of the Company’s acquisitions of interests in its subsidiaries and consolidated VIEs. Goodwill is not amortizedbut is tested for impairment on an annual basis, or more frequently if events or changes in circumstances indicate that it might be impaired. The Companyfirst assesses qualitative factors to determine whether it is necessary to perform the two-step quantitative goodwill impairment test. In the qualitativeassessment, the Company considers primary factors such as industry and market considerations, overall financial performance of the reporting unit, and otherspecific 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 lessthan 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, includinggoodwill. 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 berequired. 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 ofa reporting unit’s goodwill. The implied fair value of goodwill is determined in a manner similar to accounting for a business combination with the allocationof 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 theamounts assigned to the assets and liabilities is the implied fair value of goodwill. This allocation process is only performed for the purposes of evaluatinggoodwill impairment and does not result in an entry to adjust the value of any assets or liabilities. Application of a goodwill impairment test requiressignificant management judgment, including the identification of reporting units, allocation of assets, liabilities and goodwill to reporting units, anddetermination of the fair value of each reporting unit. No goodwill impairment losses were recognized for the years ended December 31, 2016 and 2017 based on the impairment test performed by the Group. (m)Intangible assets Intangible assets, which include computer software, internal use software development costs, online game licenses, domain names, land use right, trademarks,technology (including right-to-use) and non-compete agreement, are carried at cost less accumulated amortization and impairment loss, if any. Exclusivegame licenses are amortized using the straight-line method over their licensing period of three years. Computer software, internal use software and domainname are amortized using the straight-line method over their estimated useful life of five years. Land use right is amortized using the straight-line methodover their estimated useful life of thirty years. (n)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 carryingamount 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 ofidentifiable 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 theassets. 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 flowapproach or, when available and appropriate, to comparable market values. The impairment of online game licenses were USD 770,000, USD 721,000 andUSD 765,000 as of December 31, 2015, 2016 and 2017, respectively. The intangible assets arising from acquisition of Kingsoft Cloud Holdings, comprisedof trademarks, non-compete agreement, and related technology (including right-to-use), were impaired by USD 3,232,000, USD 322,000 and USD 1,381,000,respectively as of December 31, 2017. F-19  Xunlei LimitedNotes to consolidated financial statements(Amounts in US dollars unless otherwise stated) 2.Summary of significant accounting policies (Continued) (o)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 widerange 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 bereasonably 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 whenone or more future events occur or fail to occur. The Group’s management and its legal counsel assess such contingent liabilities, and such assessmentinherently involves an exercise of judgment. In assessing loss contingencies related to legal proceedings that are pending against the Group or unassertedclaims that may result in such proceedings, the Group, in consultation with its legal counsel, evaluates the perceived merits of any legal proceedings orunasserted 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 theestimated liability would be accrued in the Group’s financial statements. If the assessment indicates that a potentially material loss contingency is notprobable, but is reasonably possible, or is probable but cannot be estimated, then the nature of the contingent liability, together with an estimate of the rangeof possible loss, if determinable and material, would be disclosed. (p)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 underoperating lease are charged to the statements of comprehensive income on a straight-line basis over the period of the lease. (q)Revenue recognition The Group generates revenues from various streams. Net revenues presented in the consolidated statements of operations and comprehensive incomerepresent revenues from service and product sales net off sales discount, value-added tax and related surcharges. The Group operates a prepaid virtual itemssystem, under which, prepaid virtual items at fixed face value are sold to third parties. Virtual items purchased can be used to subscribe for membership orpurchase of virtual items in online games, as discussed below. Virtual items sold but not yet consumed by the users are recorded as “Receipts in advance fromcustomers” and upon consumption, they are recognized as membership subscription and online game revenue according to the respective prescribed revenuerecognition policies addressed below. I)Subscription revenues The Group operates a VIP membership program where VIP members can have access to high speed online acceleration services, online streaming and otheraccess 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 mobileoperators. The membership fee is collected when the subscribers pay for the monthly phone bills. The terms of time-based subscriptions range from onemonth to twelve months, with the subscribers having the option to renew the contract. The receipt of subscription fee is initially recorded as deferred revenueand revenue is recognized rateably over the period of subscription as services are rendered. Unrecognized portion beyond 12 months from balance sheet dateis classified as a long-term liability. The Group evaluated the principal versus agent criteria and determined that the Group is the principal in the transactionand accordingly record revenue on a gross basis. In determining whether to report revenues gross for the amount of subscription revenue, the Group assesseswhether 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 inthe same period as the revenue for the membership fee is recognized. F-20  Xunlei LimitedNotes to consolidated financial statements(Amounts in US dollars unless otherwise stated) 2.Summary of significant accounting policies (Continued) (q)Revenue recognition (Continued) II)Advertising revenues Advertising revenues are derived principally from arrangements where the customers pay to place their advertisements on the Group’s platform in differentformats over a particular period of time. Such formats generally includes but are not limited to videos, banners, links, logos and buttons. Advertisements onthe Group’s platform are generally charged on the basis of duration, and advertising contracts are signed to establish the fixed price and the advertisingservices to be provided. The Group enters into advertising contracts with third party advertising agencies that represents advertisers, as well as directly withadvertisers. A typical contract term would range from a few days to 3 months. Both third party advertising agencies and direct advertisers are generally billedat 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 totalconsideration to the various advertising elements based on their relative fair values and recognizes revenue for the different elements over their respectivedisplay periods. The Group determines the fair values of different advertising elements based on the prices charged when these elements were sold on astandalone basis. The Group recognizes revenue on the elements delivered and defers the recognition of revenue for the fair value of the undeliveredelements until the remaining obligations have been satisfied. Where all of the elements within an arrangement are delivered uniformly over the agreementperiod, 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 based on the following criteria: —There is persuasive evidence that an arrangement exists—the Group will enter into framework and execution agreements with the advertising agencies,specifying price, advertising content, format and timing—Price is fixed and determinable—prices charged to the advertising agencies are specified in the agreements, including relevant discount and rebate rates—Services are rendered—the Group recognizes revenue ratably over the contract period of display—Collectability is reasonably assured—the Group assesses credit history of each advertising agency before entering into any framework and executionagreements. If the collectability from the agencies is assessed as not reasonably assured, the Group recognizes revenue only when the cash is received andall the other revenue criteria are met. The Group provides sales incentives in the forms of discounts and rebates to third party advertising agencies based on purchase volume. As the advertisingagencies are viewed as the customers in these transactions, revenue is recognized based on the price charged to the agencies, net of sales incentives providedto the agencies. Sales incentives are estimated and recorded at the time of revenue recognition based on the contracted rebate rates and estimated salesvolume 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 analysissystematically. As the third party advertising platforms are viewed as the customers in these transactions, revenue is recognized monthly based on the datapublicized on third party platforms and the price charged to these advertising platforms. F-21  Xunlei LimitedNotes to consolidated financial statements(Amounts in US dollars unless otherwise stated) 2.Summary of significant accounting policies (Continued) (q)Revenue recognition (Continued) II)Advertising revenues (Continued) Transactions with advertisers The Group also enters into advertisement contracts directly with advertisers. Under these contracts, similar to transactions with third party advertisingagencies, the Group recognizes revenue ratably over the contract period of display. The terms and conditions, including price, are fixed according to thecontract between the Group and the advertisers. The Group also performs credit assessment of all advertisers prior to entering into contracts. Revenue isrecognized 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 1,179,000, USD 15,000 and USD 440,000 for the yearsended December 31, 2015, 2016 and 2017, respectively. III)Other internet value-added services i)Online game revenues 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 purchasesof virtual items including consumable and perpetual items, which can be utilized in the online games to enhance their game-playing experience. Consumableitems represent virtual items that can be consumed by a specific user within a specified period of time. Perpetual items represent virtual items that areaccessible 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 eachgame. 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 theplatform 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 onan 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 thetransaction, and the specific requirements of each contract. The Group determined that for non-exclusive game licensed arrangements, the third party gamedevelopers are the principal given that the game developers design and develop the game services offered, have reasonable latitude to establish prices ofgame virtual items, and are responsible for maintaining and upgrading the game content and virtual items. Accordingly, the Group records online gamerevenue, 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 dataon the consumption details and the types of virtual items purchased by the game players. The Group has adopted a policy to recognize revenues relating toboth 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 informationindicating a change in the game player behavioral patterns. F-22  Xunlei LimitedNotes to consolidated financial statements(Amounts in US dollars unless otherwise stated) 2.Summary of significant accounting policies (Continued) (q)Revenue recognition (Continued) III)Other internet value-added services (Continued) i)Online game revenues (Continued) 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 theprincipal, the Group records online game revenue on a gross basis, with the amount remitted to the game developers reported as cost of revenue. Paymenthandling 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 virtualitems purchased by the game players. The Group does not maintain information on consumption details of virtual items, and only have limited informationrelated to the frequency of log-ons. Given that a substantial portion of the virtual items purchased by the game players in exclusive licensed games areperpetual items, management determined that it would be most appropriate to recognize revenue over the shorter of 1) estimated lives of the games and 2) theestimated lives of the user relationship with the Group, which were approximately one to six months for the periods presented. Revenues related toconsumable 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 bythose 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 theestimated 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 periodfrom 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 Groupcategorizes these games by their nature, such as simulation games, role playing games and others, which appeal to players belonging to differentdemographics. 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 thegames 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 anduser 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’sprofile, 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 relevantinformation at the time of assessment. Adjustments arising from the changes of estimated lives of virtual items are applied prospectively as such changes areresulted from new information indicating a change in the game player behavioral patterns. Any changes in the estimates of lives of virtual items may result inthe Group’s revenues being recognized on a basis different from prior periods and may cause the Group’s operating result to fluctuate. The Group periodicallyassesses the estimated lives of the virtual items and any changes from prior estimates are accounted for prospectively. Any adjustments arising from changesin user relationship as a result of new information will be accounted as a change in accounting estimate in accordance with ASC 250 Accounting Changesand Error Corrections.

Web game revenue recognized from discontinuedoperations was USD 25,160,000, USD 15,981,000 and USD 11,428,000 for the years ended December 31, 2015, 2016 and 2017, respectively. ii)Live video revenue The Group operates live video platform and users can purchase virtual items which they can then send to performers in the live video platform. The revenuefrom live video is recognized at fair value of the virtual items, as Xunlei is the principal in this arrangement, based on actual consumption of virtual items bythe paying users. iii)Revenues from traffic referral programs The Group enters into contracts with certain third party portals/websites to earn revenue by redirecting online traffic to these third party portals/websites. Ona 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. iv)Revenues from cloud computing As part of the Group’s cloud computing business, Project Crystal, the Group engages in sale of Zhuanqianbao (“ZQB”) and OneThing Cloud. ZQB andOneThing Cloud are personal cloud hardware devices. ZQB and OneThing Cloud also allow users to share their idle bandwidth with the Group, in exchange for crystal points and LinkTokens, respectively. Crystalpoints, which can be converted into cash based on a pre-set exchange rate, will only be given to the users when they successfully shared unused bandwidthwith the Group, whereas LinkTokens are not convertible into cash but they can be redeemed for the services offered in the platforms of the Group under theterms determined by the Group. Although the Group has not publicly announced the full details of the redemption process, the LinkTokens represent theGroup’s obligation to deliver future services. Therefore, the Group receives an identifiable benefit, being the bandwidth, from the users in exchange for thecrystal points and LinkTokens. The Group determined that ZQB and OneThing Cloud sold to users represent identifiable benefit to the users that is separablefrom the ability to sell bandwidth back to the Group and the bandwidth purchased from the users represent identifiable benefit to the Group, which the Groupcan reasonably estimate the fair value of this benefit, that is separable from ZQB and OneThing Cloud. F-24  Xunlei LimitedNotes to consolidated financial statements(Amounts in US dollars unless otherwise stated) 2.Summary of significant accounting policies (Continued) (q)Revenue recognition (Continued) iv)Revenues from cloud computing (Continued) The sales of ZQB and OneThing Cloud and purchase of excess bandwidth by the Group are considered separate transactions. Therefore, sales of ZQB andOneThing Cloud are reported as revenue, while crystal points and LinkTokens given for purchase of bandwidth are reported as bandwidth cost. The Group sells ZQB and OneThing Cloud through online e-commerce platforms. The revenue from ZQB and OneThing Cloud is recognized when the itemis dispatched to the end customers. The LinkTokens issued represent the Group’s obligation to deliver future services. Therefore, deferred revenue was 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 ofLinkTokens 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 streamingplatforms. On a monthly basis, the Group records the bandwidth it delivers and recognizes revenue from these online video streamers under contractual ratesapplied (price per GB of bandwidth multiplies total GBs of bandwidth per month). The cost of collecting idle bandwidth is recorded as bandwidth costswithin 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 warrantyperiods is 1 year. The Company accrues warranty liabilities at the time of sale, based on historical and projected incident rates and expected future warrantycosts. (r)Barter transactions The Group also enters into agreements with third parties (mainly video streaming internet platform) to exchange content. The exchanged content providesrights for each respective party only to broadcast the content received on its own website; though, each party retains the right to continue broadcasting and orsub-license the rights to the content it surrendered in the exchange. These transactions are non-monetary transactions similar to barter transactions, and theGroup follows ASC 845, Non-Monetary Transactions and ASC 360-10, Property, Plant, and Equipment. Such barter transactions should be recorded at fairvalue of the surrendered assets in the transaction unless such fair value are not determinable within reasonable limits. The Group estimated the fair value ofthe content by gathering ‘‘price reference’’ of cash sub-licensing transactions of each exclusive content right and categorizing it into two buckets (1) cashtransaction prices with established counterparties and (2) cash transaction prices with less established counterparties. With this information, the Groupcalculates an ‘‘average cash transaction price’’ for each category to be used as a reference for the non-monetary transaction. The attributable cost of therelated exclusive Content Copyright surrendered is released and recorded as the cost of the barter transaction using the individual-film-forecast computationmethod. This method calculates such cost based on the ratio of the estimated fair value of the exchanged content over the aggregated estimated fair value tobe generated by the exclusive Content Copyrights for their whole license period or estimate useful lives. The Group revisits the forecast at each quarter oryear end and make adjustment, when appropriate. The Group generated net gains amounting to USD 137,000 from barter transactions, which is the net amount of proceeds of USD 409,000 after deductingrelated allocation of cost of USD 247,000 and business tax and surcharge of USD 25,000 for the year ended December 31, 2015. No similar transactionsoccurred for the years ended December 31, 2016 and 2017. F-25  Xunlei LimitedNotes to consolidated financial statements(Amounts in US dollars unless otherwise stated) 2.Summary of significant accounting policies (Continued) (s)Sales and marketing expenses Sales and marketing expenses comprise primarily of salary, commission and benefits of sales and marketing personnel and external advertising and marketpromotion expenses. The external advertising and market promotion expenses from continuing operations amounted to approximately USD 6,019,000, USD6,666,000 and USD 10,345,000 for the years ended December 31, 2015, 2016 and 2017, respectively. Shipping and handling fee is recorded in sales and marketing expenses. (t)General and administrative expenses General and administrative expenses consist primarily of salary and benefits, professional service fees, legal expenses and other administrative expenses. (u)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 isavailable, 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. Whileinternal and external costs incurred during the preliminary project stage are expensed as incurred, costs relating to activities during the applicationdevelopment stages have been capitalized. During each of the three years ended December 31, 2017, no software development costs were capitalized asintangible assets. In addition, the Group incurred other research and development costs in relation to software used to support its operations. Any development costs qualifiedfor capitalization were immaterial for the periods presented. (v)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 consequencesattributable to differences between the financial statements’ carrying amounts of existing assets and liabilities and their respective tax bases and tax loss carryforwards. 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 orsettled. 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 thatincludes the enactment date. A valuation allowance is provided to reduce the carrying amount of deferred tax assets if it is considered more likely than notthat 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 forwardcan be utilized prior to their respective expiration dates. The Group adopted the guidance regarding uncertain tax positions and evaluated its open taxpositions 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 benefitfrom that uncertain position is recognized in the Group’s consolidated financial statements if it is more likely than not that the position is sustainable uponexamination by the relevant taxing authority. The Group did not have any significant uncertain tax position and there was no effect on its financial conditionor results of operations as a result of implementing the new guidance. The Group recognizes interest and penalties accrued on any unrecognized tax benefitsas a component of income tax expense, if any. No significant interest and penalties were recorded in the years ended December 31, 2015, 2016 and 2017. F-26  Xunlei LimitedNotes to consolidated financial statements(Amounts in US dollars unless otherwise stated) 2.Summary of significant accounting policies (Continued) (v)Taxation and uncertain tax positions (Continued) 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 theperiod after crediting the input VAT for the period. In addition to the product revenues currently subject to VAT at a rate of 17%, the Group’s advertisingrevenues, subscription revenue, online game revenue, revenue from cloud computing and live video revenue are now subject to VAT at a rate of 6%. (w)Retirement benefits Full-time employees of the Company’s subsidiaries, consolidated VIE and its subsidiaries in the PRC participate in a government mandated multi-employerdefined contribution plan pursuant to which certain pension benefits, medical care, unemployment insurance, employee housing fund and other welfarebenefits are provided to employees. Chinese labor regulations require that the subsidiaries and VIEs of the Company make contributions to the governmentfor 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 5,176,000, USD 8,645,000 and USD10,123,000 for the years ended December 31, 2015, 2016 and 2017, respectively. (x)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 pricingmodel. As the Group has granted share options and restricted shares with service-only condition, the Group elected to recognize compensation costs net ofestimated forfeitures on a straight line basis over the requisite service period, which is generally the same as the vesting period. The amount of compensationcost 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. (y)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 anyconditions or specific use requirements are recorded as subsidy income in the consolidated statements of operations. Subsidies for purchase of equipment arerecorded as deferred government grant when received, and are recorded as other income over the expected useful life of the assets after the related equipmenthas been purchased. (z)Segment reporting The Group’s Chief Executive Officer has been identified as the chief operating decision maker (“CODM”), who reviews consolidated operating results of theGroup 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 betweenmarkets or segments for the purpose of internal reporting. Management has determined that the Group operates and manages its business as a single segmentwhich is the operation of its online media platform. All revenues of the Group are derived from mainland China. F-27  Xunlei LimitedNotes to consolidated financial statements(Amounts in US dollars unless otherwise stated) 2.Summary of significant accounting policies (Continued) (z)Segment reporting (Continued) An analysis of the different types of revenues for the years ended December 31, 2015, 2016 and 2017 are summarized as follows: Revenue from continuing operations Years ended December 31, (In thousands) 2015 2016 2017 Subscription revenue 82,435 90,163 84,956 Advertising revenue 4,802 16,874 22,484 Product revenue (note a) 2,512 4,543 32,894 Other internet value-added services (note b) 15,088 29,405 61,577 Total 104,837 140,985 201,911 note a:Product revenue mainly comprise of sales of ZQB and OneThing Cloud devices. note b:Other internet value-added services mainly comprise of CDN revenue, live video services, provision of technical services, traffic referral programs,and online game revenue. The Group is entitled to receive a mutually agreed revenue sharing of the net advertising income, with reference to market price, generated byBeijing Xiaomi Mobile Software on a products pre-installed with the technology solution provided by the Group for the period from January 2016to mid-June 2017 totaling USD 5.8 million, which was recognized as revenue in 2017 (note 20). (aa)Net income / (loss) per share Net basic income / (loss) per share is computed by dividing net income / (loss) attributable to holders of common shares by the weighted-average number ofcommon shares outstanding during the year using the two class method. Using the two class method, net income / (loss) is allocated between common sharesand other participating securities based on their participating rights. Net diluted income / (loss) per share is calculated by dividing net income / (loss) attributable to common shareholders as adjusted for the effect of dilutivecommon 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 income / (loss) per share if their effects would be anti-dilutive. Common shareequivalents consist of the common shares issuable upon the conversion of the stock options, using the treasury stock method. (bb)Comprehensive income Comprehensive income is defined as the change in equity of a Group during the period from transactions and other events and circumstances excludingtransactions resulting from investments from shareholders and distributions to shareholders. Accumulated other comprehensive income, as presented on theaccompanying consolidated balance sheets, consists of cumulative translation adjustment. F-28  Xunlei LimitedNotes to consolidated financial statements(Amounts in US dollars unless otherwise stated) 2.Summary of significant accounting policies (Continued) (cc)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 retainedearnings set at certain percentage of after-tax profit determined in accordance with PRC accounting standards and regulations (“PRC GAAP”). Appropriationto 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 thereserve 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 haveany 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 registeredcapital. 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 inChina as of December 31, 2016 and 2017 for the Group’s reporting purpose in China as determined under generally accepted accounting principles in China: (In thousands) December 31,2016 December 31,2017 Paid-in capital 118,733 137,194 Additional paid-in capital 161 161 Statutory reserves 5,132 5,132 Total 124,026 142,487 Relevant laws and regulations permit payments of dividends by the PRC subsidiaries and affiliated companies only out of their retained earnings, if any, asdetermined in accordance with respective accounting standards and regulations. Accordingly, the above balances are not allowed to be transferred to theCompany in terms of cash dividends, loans or advances (See also Note 27). (dd)Dividends Dividends are recognized when declared. No dividends were declared for the years ended December 31, 2015, 2016 and 2017, respectively. The Group doesnot have any present plan to pay any dividends on common shares in the foreseeable future. The Group currently intends to retain the available funds andany future earnings to operate and expand its business. (ee)Recent accounting pronouncements In November 2015, the FASB issued ASU 2015-17, Income Taxes: Balance Sheet Classification of Deferred Taxes. ASU 2015-17 simplifies the presentationof deferred income taxes, which require the deferred tax liabilities and assets be classified as noncurrent in a classified statement of financial position. ASU2015-17 is effective for fiscal years and interim periods within those years beginning after December 15, 2016. The Group has adopted this ASU for the yearended December 31 2017 and present the deferred tax assets and liabilities as non-current. Prior periods were not retrospectively adjusted. F-29  Xunlei LimitedNotes to consolidated financial statements(Amounts in US dollars unless otherwise stated) 2.Summary of significant accounting policies (Continued) (ee)Recent accounting pronouncements (Continued) In January 2016, the FASB issued ASU 2016-01, Financial Instruments–Overall: Recognition and Measurement of Financial Assets and Financial Liabilities.The new guidance will impact the accounting for equity investments, financial liabilities under the fair value option, and the presentation and disclosurerequirements for financial instruments. In addition, the FASB clarified the need for a valuation allowance on deferred tax assets resulting from unrealizedlosses on available-for-sale debt securities. The accounting for other financial instruments, such as loans, investments in debt securities, and financialliabilities not under the fair value option is largely unchanged. The standard is effective for public business entities for annual periods (and interim periodswithin those annual periods) beginning after December 15, 2017. For equity investments (except those accounted for under the equity method) with noreadily determinable fair value, the Group has elected to continuously apply cost method less impairment. However, the Group will closely monitor if anychanges resulting from observable price changes in orderly transactions for the identical or similar investment of the same issuer. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). The core principle of Topic 842 is that a lessee should recognize the assets andliabilities that arise from leases. A lessee should recognize in the balance sheet a liability to make lease payments (the lease liability) and a right-of-use assetrepresenting its right to use the underlying asset for the lease term. For leases with a term of 12 months or less, a lessee is permitted to make an accountingpolicy election by class of underlying asset not to recognize lease assets and lease liabilities. If a lessee makes this election, it should recognize lease expensefor such leases generally on a straight-line basis over the lease term. ASU 2016-02 is effective for fiscal years and interim periods within those yearsbeginning after December 15, 2018. Early adoption is permitted. The Group is currently evaluating the impact ASU2016-02 will have on the Groupconsolidated balance sheet, results of operations, cash flows and related disclosures. The FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230), Classification of Certain Cash Receipts and Cash Payments (a consensus of theEmerging Issues Task Force), on August 26, 2016, and ASU 2016-18, Statement of Cash Flows (Topic 230), Restricted Cash (a consensus of the EmergingIssues Task Force), on November 17, 2016. The new guidance is intended to reduce diversity in practice in how certain transactions are classified in thestatement of cash flows. For public business entities, both ASUs are effective for financial statements issued for fiscal years beginning after December 15,2017, and interim periods within those fiscal years. For all other entities, the guidance is effective for financial statements issued for fiscal years beginningafter December 15, 2018, and interim periods within fiscal years beginning after December 15, 2019. Early adoption is permitted for ASU 2016-18. Earlyadoption is also permitted for ASU 2016-15 provided that all of the amendments are adopted in the same period. Both ASUs require application using aretrospective transition method. The Group believes the adoption will not have material impact on the Group cash flows and related disclosures. In 2016, the FASB and IASB issued several amendments and clarifications to the new revenue standards, primarily as a result of issues raised by stakeholdersand discussed by the Transition Resource Group. Amendments were made to the guidance related to the principal versus agent assessment, identifyingperformance obligations, accounting for licenses of intellectual property, and other matters (such as the definition of completed contracts at transition, theaddition of new practical expedients, and various technical corrections). As amended, the FASB's standard is effective for public entities for the first interimperiod within annual reporting periods beginning after December 15, 2017 (nonpublic companies have an additional year). The FASB’s standard will allowearly adoption, but no earlier than the original effective date for public entities (reporting periods beginning after December 15, 2016). The IASB’s standard,as amended, is effective for the first interim period within annual reporting periods beginning on or after January 1, 2017, with early adoption permitted. F-30  Xunlei LimitedNotes to consolidated financial statements(Amounts in US dollars unless otherwise stated) 2.Summary of significant accounting policies (Continued) (ee)Recent accounting pronouncements (Continued) The core principle of the guidance is that an entity should recognize revenues to depict the transfer of promised goods or services to customers in an amountthat reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. To achieve this core principle, an entityshould apply the following steps: 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. The Group has performed a thorough assessment of the impact of new revenue standard and identified differences which may impact on the Group’sconsolidated financial statements, including but not limited to, the revenue recognition for membership subscription and live video revenue. ·Rights from membership upgrade shall be considered as a separately identifiable benefit and accounted for separately. A small portion of revenuereceived for membership subscription will be allocated to the rights of membership upgrade and impact on the timing of recognizing the revenue.However, based on the assessment, the impact is considered to be immaterial.·Free virtual items on the live video platforms shall be considered as a separate performance obligation per and accounted for separately. A smallportion of revenue received in respect of live video platforms will be allocated to the free virtual items and impact on the timing of recognizing therevenue. However, based on the assessment, the impact is considered to be immaterial. The Group will be adopting the new standard effective January 1, 2018, using the modified retrospective method. Based on the results of management’sassessment described above, the impact upon adoption is immaterial. Accordingly, management does not expect to recognize any adjustment upon initialapplication. In January 2017, the FASB issued Accounting Standards Update (“ASU”) No. 2017-01, Business Combinations (Topic 805): Clarifying the Definition of aBusiness, which clarifies the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should beaccounted for as acquisitions or disposals of assets or businesses. The standard is effective for fiscal years beginning after December 15, 2017, includinginterim periods within those fiscal years. Early adoption is permitted. The standard should be applied prospectively on or after the effective date. The Groupis currently evaluating the impact ASU2017-01 will have on the Groups consolidated balance sheet, results of operations, cash flows and related disclosures. In January 2017, the FASB issued Accounting Standards Update (“ASU”) 2017-04, Simplifying the Test for Goodwill Impairment. The guidance removesStep 2 of the goodwill impairment test, which requires a hypothetical purchase price allocation. A goodwill impairment will now be the amount by which areporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. The guidance should be adopted on a prospective basisfor the annual or any interim goodwill impairment tests beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwillimpairment tests performed on testing dates after January 1, 2017. The Group has early adopted the standard for the year ended December 31, 2017. In May 2017, the FASB issued ASU 2017-09, Compensation — Stock Compensation (Topic 718): Scope of Modification Accounting, which providesguidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting in ASC 718.Under the new guidance, modification accounting is required only if the fair value, the vesting conditions, or the classification of the award (as equity orliability) changes as a result of the change in terms or conditions. The new guidance is effective for annual periods, and interim periods within those annualperiods, beginning after December 15, 2017. Early adoption is permitted. The Group is evaluating the effects, if any, of the adoption of this guidance on theGroups consolidated balance sheet, results of operations, cash flows and related disclosures.

(“Nesound”), an independent third party. The total sales price was RMB 130,000,000 (equivalent to approximately USD19,896,000) (note 7). The disposal is due to a shift of strategy focusing on the Group’s most competitive operations. Assets and liabilities related to Xunlei Kankan were reclassified as assets/liabilities held for sale as of December 31, 2014, while results of operations relatedto Xunlei Kankan, including comparatives, were reported as loss from discontinued operations.

(“Buyer”), a company operated by a few former core members of Xunlei’s web game business. The totalsales price was RMB 4,180,000 (equivalent to approximately USD 640,000). The disposal is due to a shift of strategy to allow the Group better manage itsinternal resources, including internal traffic referral and corporate allocation. As part of the disposal and according to the Disposal Agreement, Xunlei agreed to assist the Buyer to collect and pay certain receivables and payables of theweb game business for a period of no longer than one year after the completion of disposal. In addition, the Buyer agreed to enter into business cooperationservices with Xunlei, including purchase of advertising services for not less than RMB 8,000,000 (equivalent to approximately USD 1,225,000) in the next24 months, after signing the Disposal Agreement, under a separate negotiated term. Relevant business cooperation agreements have been signed in January2018 at market term. Assets and liabilities related to web game business were reclassified as assets/liabilities held for sale as of December 31, 2017, while results of operationsrelated to web game, including comparatives, were reported as income from discontinued operations.

Stock options granted to employees and officers vest over a four-year schedule as stated below: (1)One-fourth of the options shall be vested upon the first anniversary of the grant date;(2)The remaining three quarters of the options shall be vested on monthly basis over the next thirty-six months. (1/48 of options shall be vested permonth subsequently) 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 overthe requisite service period. 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 isto attract and retain the best available personnel by linking the personal interests of the members of the board, employees, and consultants to the success ofthe 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 26,822,828shares (excluding the share options previously granted to the directors who are the founders of the Company). The amount of shares available for such grantsas of December 31, 2017 is 2,627,465. On June 11, 2014, the board of directors of the company decided to extend the contractual life for certain vested share options to June 11, 2015, because thematurity date of these options was from June to December in 2014, whereas, the lock-up period for the shares was 6 months from the IPO closing date, i.e.June 24, 2014, which would result in the expiration of these options before the exercise. The incremental share-based compensation of USD 768,000 isrecognized at the time of modification. In the business combination of personal cloud storage business completed on September 5, 2014, the Group granted share options under the 2010 Plan toreplace the unvested awards owned by the employees who are transferred to the Group, the portion of the fair-value-based measure of the replacement awardattribute to pre-combination service of USD 303,000 was allocated to the consideration, while the portion attribute to post-combination service of USD44,000 was recorded as share based compensation expense over the remaining vesting period. On December 1, 2014, the board of directors of the company approved the conversion of certain vested and unvested share options with relatively highexercise price into restricted shares. In this conversion, 3,776,711 share options were cancelled and 1,505,787 restricted shares were granted. The incrementalshare-based compensation of USD 2,214,000 is recorded over the remaining vesting period of 2 to 4.5 years. In November 2014, the Company issued to a depositary bank for American Depositary Shares, 10,000,000 common shares, which were reserved for the futureexercise of share options or vesting of restricted shares.

If necessary, forfeitures are revised in subsequent periods if actual forfeitures differ from those estimates. Basedupon the Company’s historical and expected forfeitures for stock options granted, the directors of the Company estimated that its future forfeiture rate wouldbe 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 ofDecember 31, 2016 and 2017 and the exercise price. Total fair values of share options vested as of December 31, 2016 and 2017 were USD 6,831,000 and USD 6,963,000, respectively. As of December 31, 2016 and 2017, there were USD 1,358,000 and 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 3.20 and 4.64 years, respectively. To the extent the actual forfeiture rate isdifferent from the Company’s estimate, the actual share-based compensation related to these awards may be different from the expectation. The Black-Scholes option pricing model is used to determine the fair value of the stock options granted to employees. The fair values of stock optionsgranted during the years ended December 31, 2016 and 2017 were estimated using the following assumptions: Options granted to employees Years ended December 31, 2016 2017 Risk-free interest rate(1) 0.77% to 1.76% 0.77% to 1.76%Dividend yield(2) — — Volatility rate(3) 40.07% to 43.3% 40.07% to 43.3%Expected term (in years)(4) 4.06 to 5.56 4.06 to 5.56 (1)The risk-free interest rate of periods within the contractual life of the share option is based on the USD denominated China Government Bond yieldas at the valuation dates. (2)The Company has no history or expectation of paying dividends on its common shares. (3)Expected volatility is estimated based on the average of historical volatilities of the comparable companies in the same industry as at the valuationdates. (4)The expected term is developed by assuming the share options will be exercised in the middle point between the vesting dates and maturity dates. 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”). The purpose of the planis to motivate, attract and retain the best available personnel by linking the personal interests of senior management to the success of the Group’s business. F-46  Xunlei LimitedNotes to consolidated financial statements(Amounts in US dollars unless otherwise stated) 18.Share-based compensation (Continued) 2013 share incentive plan (Continued) In November 2013, the Company issued 9,073,732 common shares to Leading Advice. Although the shares were legally issued to Leading Advice, LeadingAdvice does not have any of the rights of a typical common share holder. Leading Advice 1) is not entitled to dividends 2) does not have the right to voteprior to vesting and 3) does not have the right to sell the unvested portion of the awards or awards that have not been granted. In addition, upon 1) theliquidation of Leading Advice 2) the dissolution of Leading Advice and 3) the expiration of the 2013 Plan, common shares not granted as awards shall betransferred back to the Group at no consideration. Given the structure of this arrangement, while the common shares have been legally issued, the commonshares issued to Leading Advice do not have the attributes of unrestricted, issued and outstanding shares. Therefore, the 9,073,732 common shares issued toLeading Advice are accounted as treasury shares until these common shares are earned by the senior management or employees for service provided to theGroup. For the awards that have been granted and become vested, Leading Advice held shares for the grantees’ benefit and exercise the voting rights on their behalf.The grantees will be entitled to dividends and have the right to request Leading Advice to transfer vested award to a transferee designated by the grantees.Shares that have been granted and vested continued to be held by and voting rights exercised by Leading Advice on behalf of the grantee at the closing of aQIPO. Before the closing of a QIPO, the Company would have a “right of first refusal” with respect to any proposed transfer of vested restricted shares. After theclosing of a QIPO, vested restricted shares may not be sold or transferred for a period of six months or a period of time determined by the underwriter (the‘‘lock up period’’). If the grantee terminates its employment prior to the closing date of a QIPO and a trade sale, the Group would have the right to acquire thevested restricted shares from the senior officer at a market price as determined by third-party valuation experts. Upon the closing of IPO, the administrator of the 2013 Plan was changed from Leading Advice to the Company’s compensation committee. Under the 2013 Plan, the maximum number of restricted shares that may be granted is 9,073,732 shares. As of December 31, 2017, 8,664,980 (2016: 8,664,980) restricted shares were granted to few senior officers.

Moreover, the current EIT Law treats enterprises established outside of China with “effective management and control” located in the PRC as PRC residententerprises for tax purposes. The term “effective management and control” is generally defined as exercising overall management and control over thebusiness, personnel, accounting, properties, etc. of an enterprise. The Company, if considered a PRC resident enterprise for tax purposes, would be subject tothe PRC Enterprise Income Tax at the rate of 25% on its worldwide income for the period after January 1, 2008. As of December 31, 2017, the Company hasnot accrued for PRC tax on such basis. The Company will continue to monitor its tax status.

Shenzhen Xunlei was entitled to capitalize the amounts as intangible assets for tax purposes and the respective amortizationcharges could be entitled to claim tax deduction. As a result, this transaction had created a temporary difference between the accounting base (on agroup basis) and the tax base (on Shenzhen Xunlei standalone basis) and led to origination of a deferred tax asset.

In 2017, valuation allowance was provided for net operating loss carryforwards ofBeijing Xunlei, Xunlei Games, Onething, Beijing Xunjing and Crystal Interactive because it was more likely than not that such deferred tax assets will not berealized 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. As of December 31, 2017, the tax returns of the Group’s subsidiaries, VIE and its subsidiaries since their respective dates of incorporation are still opento examination. 22.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 formeasuring fair value and expands financial statement disclosures about fair value measurements. Although adoption did not impact the Group’s consolidatedfinancial 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 marketsLevel 2—Include other inputs that are directly or indirectly observable in the marketplace or based on quoted price in markets that are not activeLevel 3—Unobservable inputs which are supported by little or no market activity and are significant to the overall fair value measurement F-57  Xunlei LimitedNotes to consolidated financial statements(Amounts in US dollars unless otherwise stated) 22.Fair value measurements (Continued) ASC 820-10 describes three main approaches to measuring the fair value of assets and liabilities: (1) market approach; (2) income approach and (3) costapproach. The market approach uses prices and other relevant information generated from market transactions involving identical or comparable assets orliabilities. The income approach uses valuation techniques to convert future amounts to a single present value amount. The measurement is based on thevalue indicated by current market expectations about those future amounts. The cost approach is based on the amount that would currently be required toreplace 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, 2016 and 2017.

Payments under operating leases are expensed on astraight-line basis over the periods of the respective leases, including any free rental periods. Total office rental expenses under all operating leases were USD 2,751,000, USD 2,382,000 and USD 2,976,000 for the years ended December 31, 2015, 2016and 2017, respectively.

Payments under bandwidth leases are expensedon a straight-line basis over the duration of the respective lease periods, including any lease free periods. Total bandwidth leasing costs for continuing operations under all operating leases were USD 37,218,000, USD 55,135,000 and USD 68,441,000 for the yearsended December 31, 2015, 2016 and 2017. Total bandwidth leasing costs for discontinued operations under all operating leases were USD 2,983,000, nil andnil for the years ended December 31, 2015, 2016 and 2017.

These cases are substantially related to alleged copyright infringement as well asroutine and incidental matters to its business, among others. Adverse results in these lawsuits may include awards of damages and may also result in, or evencompel, a change in the Group’s business practices, which could impact the Group’s future financial results. The Group had incurred USD 3,307,000, USD1,669,000 and USD 9,453,000 legal and litigation related expenses for the years ended December 31, 2015, 2016 and 2017, respectively. For the year endedDecember 31, 2017, legal and litigation related expenses include a settlement of USD3.9 million reached during the year. Up to April 25, 2018, which is the date when the consolidated financial statements were issued, the Group had 42 lawsuits pending against the Group with anaggregate amount of claimed damages of approximately RMB 112 million (USD 16.76 million) which occurred before December 31, 2017 (2016: RMB89.27 million (USD 12.87 million)). Of the 42 pending lawsuits, 39 lawsuits were relating to the alleged copyright infringement in the PRC. The Group hadaccrued for USD 1,755,000 litigation related expenses in ‘‘Accrued expenses and other liabilities’’ in the consolidated balance sheet as of December 31, 2017(2016: USD 2,062,000), 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 advicesfrom 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 ofunsettled litigation and claims cannot be predicted with certainty, the Group does not expect that the outcome of the 42 lawsuits will result in the amountsaccrued materially different from the range of reasonably possible losses. In the opinion of management, there was not at least a reasonable possibility theCompany 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 otherclaims. However, the outcome of litigation is inherently uncertain. If one or more of these legal matters were resolved against the Company in a reportingperiod for amounts in excess of management’s expectations, the Company’s consolidated financial statements for that reporting period could be materiallyadversely 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, whichare six major U.S. entertainment content providers. In that agreement, the Group agreed to implement a comprehensive system of measures designed toprevent unauthorized downloading of and access to such content providers’ works. After beginning the roll-out for several months, the Group suspendedimplementation of the filter but have identified and are in the process of implementing a new filter. Even with the implementation of a new filter, however,the Group’s copyright protection measures would not be able to fully protect the Group against copyright infringement suits. In January 2015, a number ofMPAA 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 theGroup infringed the plaintiffs’ copyright on 13 of 28 video products and were required by the court to compensate the plaintiff for a total of RMB1.4 million.As of the date of this annual report, those cases are awaiting decisions of appellate court. F-60  Xunlei LimitedNotes to consolidated financial statements(Amounts in US dollars unless otherwise stated) 25.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 ofonline video and online advertising services. Specifically, foreign ownership in an internet content provider or other value-added telecommunication serviceproviders may not exceed 50%. The Group conducts its operations in China principally through contractual arrangements among Giganology Shenzhen, itswholly-owned PRC subsidiary, and Shenzhen Xunlei and its shareholders. Shenzhen Xunlei holds the licenses and permits necessary to conduct its resourcediscovery network, online advertising, online games and related businesses in China and hold various operating subsidiaries that conduct a majority of itsoperations in China. The Company conducts all of its operations in China through, Shenzhen Xunlei, a variable interest entity, which it consolidates as aresult of a series contractual arrangements enacted. If the Company had direct ownership of Shenzhen Xunlei, it would be able to exercise its rights as ashareholder to effect changes in the board of directors of Shenzhen Xunlei, which in turn could effect changes at the management level, subject to anyapplicable fiduciary obligations. However, under the current contractual arrangements, it relies on Shenzhen Xunlei and its shareholders’ performance of theircontractual obligations to exercise effective control. In addition, its operating contract with Shenzhen Xunlei has a term of ten years, which is subject toGiganology 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 withPRC law and are legally enforceable. However, the Chinese government may issue from time to time new laws or new interpretations on existing laws toregulate this industry. Regulatory risk also encompasses the interpretation by the tax authorities of current tax laws, and the Group’s legal structure and scopeof 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. ThePRC government may also require the Company to restructure the Group’s operations entirely if it finds that its contractual arrangements do not comply withapplicable 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 theGroup 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 ofany 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 anyof 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, theGroup would no longer be able to consolidate the VIE. The Group does not believe that any penalties imposed or actions taken by the PRC Governmentwould result in the liquidation of the Company, Giganology Shenzhen or Shenzhen Xunlei. As of December 31, 2017, the aggregate loss and distributable reserves of VIE and VIE’s subsidiaries amounted to approximately USD 32,222,000 and theaggregate retained earnings and distributable reserves amounted to USD 2,541,000 as of December 31, 2016, which has been included in the consolidatedfinancial 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 rightsof 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 futurefinancial position, results of operations or cash flows. However, the Group believes this is a normal business risk many companies face. The Group willcontinue to closely monitor the financial conditions of Shenzhen Xunlei and its subsidiaries. F-61  Xunlei LimitedNotes to consolidated financial statements(Amounts in US dollars unless otherwise stated) 25.Certain risks and concentration (Continued) PRC regulations (Continued) Shenzhen Xunlei and its subsidiaries’ assets comprise both recognized and unrecognized revenue-producing assets. The recognized revenue-producing assetsinclude intangible assets, purchased property and equipment. The balances of these assets held by the VIE and its subsidiaries are included in “property andequipment, net” and “intangible assets, net” in the consolidated balance sheet and specifically in the VIE table on the following page. The unrecognizedrevenue-producing assets mainly consist of license, patents, trademarks, and domain names which are not recorded in the financial statement as they didn’tmeet 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 toproduce and broadcast internet, radio, and television programs. One of them is the ICP licenses as described in note 1. As of December 31, 2017, Shenzhen Xunlei and its subsidiaries held patents granted in the PRC and in the United States. Presently, patent applications arebeing examined by the State Intellectual Property Office of the PRC and also patent application is being reviewed by the United States Patent and TrademarkOffice. As of December 31, 2017, Shenzhen Xunlei and its subsidiaries have applied to register trademarks, of which the Company has received registered trademarksin different applicable trademark categories including registered with World Intellectual Property Organization.

The RMB is not freely convertible into foreign currencies. Remittances of foreigncurrencies into the PRC and exchange of foreign currencies into the RMB require approval by foreign exchange administrative authorities and certainsupporting documentation. The State Administration for Foreign Exchange, under the authority of the People’s Bank of China, controls the conversion of theRMB into other currencies. The revenues and expenses of the Company’s subsidiaries, consolidated VIE and its subsidiaries are generally denominated in theRMB and their assets and liabilities are denominated in the RMB. Concentration of customer risk The top 10 customers accounted for 26%, 18% and 27% of the net revenues for the years ended December 31, 2015, 2016 and 2017, respectively. Prior toentering into sales agreements, the Group performs credit assessments of its customers to assess the credit history of its customers. Further, the Group has notexperienced any significant bad debts with respect to its accounts receivable. Credit risk As of December 31, 2016 and 2017, substantially all of the Group’s cash and cash equivalents were held at reputable financial institutions in the jurisdictionswhere the Group and its subsidiaries are located. The Group believes that it is not exposed to unusual risks as these financial institutions have high creditquality. 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 the credit history of its customers. Further, the Grouphas not experienced any significant bad debts with respect to its accounts receivable. 26.Subsequent events Restricted shares grant In March 2018, 2,815,520 restricted shares had been granted to certain executive officers or employees of the Group under the 2010 share incentive plan. Investments In November 2017, the Group has prepaid USD 1.5 million (RMB 9.6 million) to Henan Zhaoteng Investment Co., Ltd. for acquisition 80% of its equityinterests in Henan Tourism Information Co., Ltd. This acquisition was not closed as of April 25, 2018. F-64  Xunlei LimitedNotes to consolidated financial statements(Amounts in US dollars unless otherwise stated) 26.Subsequent events (continued) Class action lawsuits against the Company In January 2018, two putative shareholder class action lawsuits were filed in the United States District Courts for the Southern District of New York againstXunlei and certain of its current and former officers and directors: Dookeran v. Xunlei Limited, et al. (filed on January 18, 2018, Case No: 18-cv-467(S.D.N.Y.)), and Peng Li v. Xunlei Limited, et al. (filed on January 24, 2018, Case No. 18-cv-646 (S.D.N.Y.)). Purporting to sue on behalf of all investors whopurchased or acquired Xunlei stock from October 10, 2017, to January 11, 2018, Plaintiffs allege that certain statements regarding OneCoin (now called“LinkToken”) in the Company’s press releases and on a quarterly investor call were false and misleading because, among other things, they failed to disclosethat OneCoin was a disguised “initial coin offering” and “initial miner offering” and constituted “unlawful financial activity.” Plaintiffs seek to recoverunder 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 actionsunder the caption In re Xunlei Limited Securities Litigation, No. 18-cv-467 (RJS), and appointed lead plaintiffs and lead plaintiffs’ counsel. The proceedingsare still at an early stage, and the consolidated amended complaint has not yet been filed. Given the early stage of the proceedings, no provision in respect of these putative class action lawsuits is considered necessary apart from the legal fee to beaccrued in 2018 according to ASC450-20-25, which requires an estimated loss from a loss contingency be accrued by a charge to income if both probableand reasonably estimable. Sale of web game business On December 28, 2017, Xunlei entered into a legally binding agreement to sell its web game business with Xunyi. The disposal was completed in January2018 with a disposal gain recorded approximate USD 1,400,000 in 2018 (note 3). 27.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 theirretained earnings, if any, as determined in accordance with PRC accounting standards and regulations. In addition, the Company’s subsidiaries, VIE andVIE’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(cc)) 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 124,026,000 and USD 142,487,000 as of December 31, 2016 and 2017, respectively. Even though the Companycurrently does not require any such dividends, loans or advances from the PRC subsidiaries, VIE and VIE’s subsidiaries for working capital and other fundingpurposes, the Company may in the future require additional cash resources from the Company’s subsidiaries, VIE and a VIE’s subsidiaries in China due tochanges in business conditions, to fund future acquisitions and development, or merely to declare and pay dividends to make distributions to shareholders. F-65  Xunlei LimitedNotes to consolidated financial statements(Amounts in US dollars unless otherwise stated) 28.Additional information: condensed financial statements of the Company Regulation S-X require condensed financial information as to financial position, statement of cash flows and results of operations of a parent company as ofthe same dates and for the same periods for which audited consolidated financial statements have been presented when the restricted net assets ofconsolidated and unconsolidated subsidiaries together exceed 25 percent of consolidated net assets as of the end of the most recently completed fiscal year.
